BUYER GUIDE | GRASPER SELECTION

Types of Laparoscopic Graspers and Their Uses

Laparoscopic graspers are long-shaft instruments used to hold, retract, manipulate or present tissue during minimally invasive surgery. Common types include atraumatic fenestrated, bowel, Babcock, Johan, Maryland, dolphin-nose, toothed and claw graspers.

The right grasper must be selected according to the tissue, required holding force, procedure, jaw pattern, shaft diameter, working length, handle, rotation and energy compatibility. A grasper's commercial name alone is not enough for safe selection.

Core Distinction

Atraumatic vs Traumatic Graspers

One of the first buying decisions is whether the instrument needs a broad, less aggressive hold or a concentrated, firm grip.

Atraumatic Laparoscopic Graspers

Atraumatic graspers are designed to distribute pressure over a broader contact area and reduce concentrated tissue engagement compared with toothed or claw-type designs. They may be considered for manipulating:

  • Bowel • Stomach • Fallopian tubes
  • Ovarian tissue • Bladder • Peritoneum
  • Other delicate or tubular structures

“Atraumatic” does not mean that tissue injury is impossible. Excessive force, prolonged clamping, inappropriate jaw selection or repeated manipulation can still damage tissue.

Traumatic Laparoscopic Graspers

Traumatic graspers use teeth, sharper serrations or claw-like features to produce a firmer localized hold. They may be considered for:

  • Fascia • Tough connective tissue
  • Specimen handling • Tissue intended for removal
  • Structures where a stronger grip is clinically appropriate

They should not be selected for delicate tissue unless their use is specifically appropriate for the procedure.

Detailed Breakdown

Individual Grasper Types — Selection Details

Confirm the exact product specification and instructions for use before ordering any instrument.

01

Atraumatic Fenestrated Grasper

A fenestrated grasper contains openings in its jaws. Its broader profile can distribute force across a larger area than a narrow or sharply toothed jaw.

Typical Uses

  • Holding and retracting delicate tissue
  • Presenting tissue for dissection
  • Manipulating bowel or tubular structures
  • Gynecology and general surgery

Confirm Before Buying

  • Fenestration size and shape • Jaw length/width
  • Serration pattern • Single or double-action jaws
  • Ratchet availability • Shaft rotation
  • Diameter and working length

Fenestrated does not automatically mean atraumatic. Check the actual edge profile, teeth and intended use.

02

Laparoscopic Bowel Grasper

A bowel grasper generally has long, broad jaws intended to hold or manipulate delicate bowel tissue while distributing pressure.

Typical Uses

  • Bowel manipulation and retraction
  • Presenting intestinal tissue
  • Supporting exposure of operative area
  • Selected delicate structures

Evaluate

  • Jaw width • Jaw length • Fenestration
  • Edge profile • Closing pressure
  • Ratchet or non-ratchet • Ease of release
  • Handle feedback

A bowel grasper should not be assumed safe for unrestricted clamping. Apply only the force and duration appropriate for the tissue.

03

Babcock Grasper

A laparoscopic Babcock grasper typically has rounded, fenestrated jaws intended to surround or hold tissue over a relatively broad area.

May Be Considered For

  • Tubular structures • Bowel
  • Fallopian tubes • Appendix
  • Ureter or similar structures (when appropriate)
  • General atraumatic manipulation

Confirm

  • Jaw opening • Fenestration shape • Tip profile
  • Ratchet design • Shaft diameter
  • Working length • Jaw mobility
  • Intended tissue applications

Do not treat every rounded fenestrated jaw as an identical Babcock design.

04

Johan Grasper

The Johan grasper is commonly offered with a fenestrated, atraumatic-style jaw for general tissue holding and retraction.

Typical Uses

  • General laparoscopic grasping and retraction
  • Bowel manipulation
  • Gynecology and general surgery
  • Holding tissue during dissection

Check

  • Jaw width, length, serration pattern
  • Fenestrated profile • Ratchet setting
  • Single- or double-action jaw • Rotation
  • Reusable or single-use status

“Johan” may describe different jaw patterns across suppliers. Request a technical drawing or sample before bulk ordering.

05

Maryland Grasper / Dissector

A Maryland-pattern instrument generally has fine, curved and tapered jaws. Frequently described as a dissector; some suppliers also classify it as a grasping and dissecting forceps.

Typical Uses

  • Fine tissue dissection • Blunt dissection
  • Tissue separation • Controlled grasping
  • Passing around selected structures
  • Presenting tissue during dissection

Confirm

  • Jaw curvature • Tip fineness • Serration
  • Single- or double-action movement
  • Insulation • Monopolar or bipolar capability
  • Compatible cable or generator, where applicable

Fine Maryland jaws are not a substitute for broad atraumatic bowel graspers. The narrower contact area can create a more concentrated grip.

06

Dolphin-Nose Grasper

A dolphin-nose grasper normally has a rounded or tapered distal profile designed for general tissue handling and dissection.

Typical Uses

  • General grasping and tissue manipulation
  • Blunt dissection • Presenting tissue
  • Working in narrower anatomical spaces

Verify

  • Exact tip shape • Serration pattern
  • Jaw curvature • Fenestrated or solid
  • Degree of tissue grip • Intended application

The term “dolphin nose” is not always standardized between suppliers. Product-code confirmation is important.

07

Alligator Grasper

An alligator-style grasper generally has elongated jaws with serrations designed to provide firmer engagement than a broad atraumatic jaw.

Typical Uses

  • Firm tissue holding
  • Manipulation of suitable tissue
  • Retrieval of selected material

Check

  • Serration depth • Jaw length • Tip shape
  • Closing force • Ratchet
  • Suitability for intended tissue

Should not automatically be used on delicate bowel or vascular structures.

08

Toothed Grasper

A toothed grasper has one or more teeth designed to engage tissue more positively. Common configurations: 1×2 teeth, 2×3 teeth, rat-tooth pattern, fine or heavy toothed jaws.

Typical Uses

  • Holding fascia • Grasping tougher tissue
  • Specimen handling • Tissue for removal
  • Situations requiring localized grip

Confirm

  • Number and arrangement of teeth • Tooth size
  • Tip alignment • Jaw closure
  • Intended tissue • Required holding force

Teeth must meet correctly when the jaw closes. Bent or misaligned teeth can affect performance and may damage tissue.

09

Rat-Tooth Grasper

A rat-tooth grasper uses a prominent tooth or interlocking tooth arrangement to provide a concentrated hold.

Typical Uses

  • Firmly holding suitable tissue
  • Grasping tissue intended for excision
  • Specimen manipulation • Selected traction

Evaluate

  • Tooth alignment • Tooth projection • Jaw strength
  • Lock mechanism • Intended use
  • Risk to surrounding tissue

This is generally not an atraumatic design.

10

Claw Grasper

A claw grasper has multiple prongs or a claw-like jaw that closes around the intended object or tissue.

Typical Uses

  • Specimen retrieval • Holding firm material
  • Stone or foreign-body retrieval
  • Tissue intended for removal

Confirm

  • Number of prongs • Prong sharpness
  • Maximum opening • Retrieval capacity
  • Shaft diameter • Compatible access system

Claw graspers should not be confused with atraumatic tissue-holding forceps.

11

Biopsy Grasper

A biopsy grasper generally has cup-shaped jaws intended to obtain a tissue sample.

Typical Uses

  • Taking selected tissue samples
  • Procedure-specific diagnostic/operative work

Confirm

  • Cup diameter • Cutting-edge design
  • Spike or non-spike • Sample capacity
  • Shaft length • Reusable/single-use status

A biopsy forceps should be used only for its documented purpose and by appropriately qualified clinicians.

12

Monopolar Laparoscopic Grasper

Some insulated grasping or dissecting forceps include a monopolar connection, combining grasping with electrosurgical capability.

Typical Functions

  • Grasping • Dissection
  • Monopolar coagulation
  • Monopolar cutting or tissue division

Confirm

  • Whether monopolar activation is permitted
  • Insulation condition • Connector type
  • Cable and generator compatibility
  • Inspection and testing requirements

Do not connect a mechanical-only grasper to electrosurgical equipment without proper documentation.

13

Bipolar Laparoscopic Grasper

A bipolar grasper uses two conductive poles within the jaw system and must be connected to compatible bipolar electrosurgical equipment.

Typical Functions

  • Tissue grasping • Controlled bipolar coagulation
  • Vessel or tissue sealing (specialized devices)
  • Dissection

Confirm

  • Intended function • Supported tissue range
  • Compatible generator • Operating instructions
  • Not every bipolar grasper is a vessel sealer

Not every bipolar grasper is a vessel sealer. Confirm the exact intended use and supported generator.

Specification Guide

Jaw Features, Diameter, Length & Handle

Common Jaw Features Explained

  • Fenestrated jaws: Openings within the jaw reduce solid contact area and may support broader tissue engagement.
  • Serrated jaws: Serrations improve mechanical grip. Depth and pattern influence engagement aggressiveness.
  • Smooth jaws: Less aggressive contact; less grip on some structures.
  • Toothed jaws: Concentrated engagement. Selected when a firm grip is required.
  • Single-action jaws: One jaw moves while the other remains relatively fixed.
  • Double-action jaws: Both jaws move during opening and closing. May support centered engagement.

Neither jaw-action design is universally superior. Access space, tissue, visibility and surgeon preference should guide selection.

Diameter, Length & Handle Selection

Common Shaft Diameters:

Approx 3 mm / 3.5 mm (mini-laparoscopy) • 5 mm (conventional) • 10 mm • Procedure-specific sizes. Confirm against trocar internal diameter, cannula seal, reducer requirements and maximum closed-jaw profile.

Common Working Lengths:

30 cm • 33 cm • 36 cm • 43 cm • 45 cm or extended. Depends on port placement, anatomy, patient build, specialty and bariatric access requirement.

Handle Types:

  • Pistol-grip • Ring/scissor-style • Axial handles
  • Ratcheted • Non-ratcheted • Switchable ratchets
  • Rotating controls • Monopolar connectors

For delicate tissue, the lock must not encourage excessive or prolonged compression. Test with expected gloves, hand position and procedure duration.

CSSD Guidelines

Reprocessing & Pre-Use Inspection

Reprocessing Reusable Graspers

Reusable graspers may contain hinges, internal rods, narrow channels, rotating mechanisms, jaw joints and closely fitted surfaces where debris can collect. Follow the product-specific process for:

  • Point-of-use handling • Safe transport
  • Disassembly (where required) • Cleaning
  • Brushing and flushing • Rinsing • Drying
  • Inspection • Reassembly • Packaging
  • Sterilization • Storage

For monopolar or bipolar instruments, visual inspection alone may not be sufficient. Follow the manufacturer’s prescribed electrical and insulation-testing process.

Pre-Use Inspection Checklist

Check a reusable laparoscopic grasper for:

  • Visible cleanliness • Jaw alignment • Tooth alignment
  • Smooth opening and closing • Ratchet engagement and release
  • Rotation control • Shaft straightness
  • Loose jaw components • Worn serrations
  • Cracks or deformation • Corrosion or pitting
  • Blocked flushing ports • Damaged insulation
  • Loose electrical connectors • Correct assembly • Missing parts

Remove any questionable instrument from use and send it for authorized assessment.

Common Procurement Mistakes

  • Ordering only by grasper name: “Babcock,” “Johan” and “dolphin nose” can describe different jaw profiles across suppliers.
  • Treating every fenestrated grasper as atraumatic: Some fenestrated jaws may still contain aggressive serrations or teeth.
  • Selecting a traumatic jaw for delicate tissue: A concentrated grip can be unsuitable for bowel or other delicate structures.
  • Ignoring jaw dimensions: Jaw length, width, opening and contact area affect tissue handling.
  • Failing to specify energy capability: A mechanical, monopolar and bipolar instrument may look similar but cannot be used interchangeably.
  • Ignoring trocar compatibility: Nominal diameter alone may not confirm compatibility with the intended cannula or seal.
  • Accepting unapproved substitutions: State the product code, jaw pattern, dimensions and approved equivalent criteria.

Hospital Sets & Medical College Training

A general laparoscopic instrument set may include:

  • Atraumatic fenestrated grasper • Bowel grasper
  • Babcock grasper • Johan grasper • Maryland dissector
  • Toothed grasper • Monopolar grasping forceps
  • Bipolar forceps • Laparoscopic scissors
  • Needle holder • Suction and irrigation instrument

Medical college training set may contain:

  • Broad atraumatic • Fenestrated bowel • Babcock-type
  • Maryland dissector • Toothed grasper
  • Ratcheted and non-ratcheted handles • Rotating instruments
  • Matching trocars • Endo trainer • Training models

Training instruments should be inspected regularly because repeated drops, excessive force and incorrect assembly can damage jaws, shafts and ratchets.

Frequently Asked Questions

Quick answers to the most common questions about laparoscopic grasper selection and procurement.

It is used to grasp, hold, retract, manipulate or present tissue during minimally invasive surgery. Its exact use depends on the jaw design and product instructions.

Common types include atraumatic fenestrated, bowel, Babcock, Johan, Maryland, dolphin-nose, alligator, toothed, rat-tooth, claw and bipolar graspers.

It is a grasper designed to distribute pressure and provide less aggressive tissue engagement than a toothed or claw-type instrument. It can still cause injury if used incorrectly.

A traumatic grasper uses teeth, strong serrations or claw-like features to provide a firmer, more localized grip on suitable tissue or material.

A broad, atraumatic bowel grasper is commonly considered for bowel manipulation. The exact jaw design and intended use must be verified before selection.

It is commonly used to hold tubular or delicate structures with a broad, fenestrated jaw. Applications depend on the product and procedure.

A Johan grasper is generally a fenestrated, atraumatic-style instrument used for tissue holding and retraction. Jaw designs may vary by manufacturer.

It can be described as a Maryland grasper, dissector or grasping-and-dissecting forceps. It normally has fine curved jaws suited to controlled manipulation and dissection.

It means the jaw contains one or more openings. Fenestration may support broader tissue engagement, but it does not automatically make the instrument atraumatic.

A single-action instrument moves one jaw, while a double-action instrument moves both jaws. Suitability depends on access, tissue and surgeon preference.

A ratchet can maintain jaw closure without constant hand pressure. Non-ratcheted handles may provide more direct control and quicker release.

Choose the diameter according to the intended trocar and procedure. Approximately 5 mm is commonly available, while smaller or larger instruments may suit specific requirements.

The length depends on port placement, anatomy and procedure. Standard models may be around 30–36 cm, while longer instruments may be used for selected deep-access or bariatric procedures.

No. Only use monopolar or bipolar energy when the exact instrument is designed for it and connected to compatible equipment according to its instructions.

No. Some bipolar instruments provide coagulation without having an approved vessel-sealing function. Confirm the exact intended use and supported generator.

Not automatically. Follow the current reprocessing instructions for each exact product, including cleaning, disassembly and permitted sterilization parameters.

Inspect cleanliness, jaw alignment, serrations, teeth, movement, ratchet, rotation, shaft, insulation, connectors and assembly according to the product instructions and hospital policy.

Not necessarily. The rotating mechanism adds surfaces that may require additional cleaning steps. Follow the specific instructions for use for each model.

Bharat Surgical supplies reusable laparoscopic grasping and dissecting instruments. Exact jaw patterns, sizes, configurations and availability should be confirmed during enquiry.
