Which type of biopsy forceps is most commonly used for standard mucosal biopsies?
Alligator forceps
Standard cup forceps
Jumbo cup forceps
Rat tooth forceps
Standard cup forceps are designed for routine mucosal sampling and are widely used in endoscopic biopsies for their versatility and ease of use.
What is the primary function of biopsy forceps in endoscopic procedures?
Dilating strictures
Suctioning fluids from the lumen
Retrieving foreign bodies
Obtaining tissue samples for histological analysis
Biopsy forceps are instruments for cutting and retrieving small tissue pieces, which are then sent for microscopic examination and histological diagnosis.
Which part of the biopsy forceps directly grasps the tissue sample?
Shaft lumen
Rotational knob
Cup jaws
Handle rings
The cup jaws at the distal tip are designed to open and close around tissue, making them the primary component for capturing samples.
Which sterilization method is recommended for reusable biopsy forceps?
Autoclaving with steam under pressure
Exposure to UV light only
Wiping with isopropyl alcohol
Rinsing with cold saline
Steam autoclaving is a validated high-temperature method that ensures eradication of microbial contaminants on reusable surgical instruments.
What feature of smooth cup biopsy forceps minimizes tissue crushing?
Serrated edges on the cups
Thicker cup walls
Larger cup capacity
Smooth cup surfaces
Smooth cups distribute pressure evenly across tissue, reducing localized compressive forces and minimizing crush artifacts in the specimen.
Which forceps type is ideal for collecting larger tissue specimens?
Disposable punch forceps
Alligator forceps
Jumbo cup forceps
Rat tooth forceps
Jumbo forceps have a larger cup diameter that enables the collection of greater tissue mass, making them suitable when larger specimens are required.
When targeting fibrotic or tough tissue, which forceps are most appropriate?
Smooth cup forceps
Rat tooth forceps
Jumbo forceps
Polypectomy snare
Rat tooth forceps feature serrated tips that provide strong grip on dense or fibrotic tissue, reducing slippage during sampling.
Which tissue characteristic is crucial when selecting biopsy forceps?
Tissue color
Tissue vascularity
Tissue consistency (firmness)
Tissue motility
Firmness and consistency influence the gripping force and cup design required to obtain an adequate tissue specimen without excessive crushing.
What handling technique can reduce crush artifact during tissue sampling?
Closing cups rapidly
Advancing forceps without opening
Applying maximum closure pressure
Closing cups gently and steadily
Gentle and controlled closure minimizes mechanical stress on cells, reducing artifact and preserving tissue architecture for accurate diagnosis.
What is the recommended finger placement on biopsy forceps handles?
Thumb only on lever, other fingers on shaft
Index finger on lever, thumb on shaft
Thumb and index finger in rings, middle finger supporting the lever
All fingers in rings
Proper finger placement provides stability and precise control of opening and closing actions during tissue sampling.
How often should biopsy forceps be tested for mechanical function when preparing for a procedure?
Before each clinical use
Only after sterilization
Once a month
Annually during maintenance
Pre-use testing before each procedure ensures smooth opening and closing to prevent instrument failure during critical sampling tasks.
What visual inspection should be performed on biopsy forceps before use?
Measure shaft length
Confirm handle color
Examine for discoloration only
Check jaws for distortion, burrs, or misalignment
Inspecting the jaws for damage prevents inadequate tissue capture, reduces tissue trauma, and lowers the risk of instrument breakage.
Which high-level disinfection agent is commonly used for endoscopic biopsy forceps?
2% glutaraldehyde
Enzymatic detergent only
3% hydrogen peroxide
70% isopropyl alcohol
2% glutaraldehyde is a widely accepted high-level disinfectant for heat-sensitive endoscopic accessories, effectively eliminating pathogens.
What safety consideration should be observed when passing forceps through the endoscope channel?
Ensure visualization before advancing
Angle the forceps sharply
Leave forceps partially inserted
Use excessive force if resistance is felt
Visual guidance during insertion helps avoid channel damage and reduces the risk of patient injury or instrument malfunction.
If resistance is encountered when inserting biopsy forceps, what is the recommended action?
Ignore and proceed
Withdraw and inspect for obstruction or damage
Twist the forceps repeatedly
Push harder until it advances
Withdrawing and inspecting the forceps prevents equipment damage and potential patient harm from forcing an obstructed instrument.
Which material offers the best resistance to corrosion for reusable biopsy forceps?
Titanium alloy
Carbon fiber
Stainless steel
Brass composite
Titanium alloys resist corrosion, are biocompatible, and maintain structural integrity through repeated sterilization cycles, extending instrument lifespan.
For biopsies requiring precise orientation in the stomach, which feature of forceps is most beneficial?
Rotatable handle mechanism
Single-use plastic construction
Fixed 90-degree angle
Alligator-shaped jaws
A rotatable handle allows adjustment of jaw orientation within the lumen, enabling targeted sampling from specific gastric sites.
What advantage do spike-equipped biopsy forceps provide when sampling subepithelial lesions?
Smaller sample size
Lower risk of bleeding
Reduced tissue penetration
Enhanced grip on dense tissue
Spikes penetrate fibrous or subepithelial tissue to secure and stabilize firm specimens, improving sample adequacy from deeper lesions.
After reprocessing, which maintenance step helps preserve the smooth action of biopsy forceps?
Exposing to direct sunlight
Applying instrument-grade lubricant to joints
Soaking in saline overnight
Storing in sealed plastic without drying
Applying a surgical-grade lubricant to the hinge and joints prevents corrosion, reduces friction, and maintains instrument maneuverability.
What is the recommended frequency for preventive maintenance by the manufacturer for biopsy forceps?
Only when instrument fails
Every 6 - 12 months
Every 5 years
Every month
Regular preventive maintenance every six to twelve months ensures functional integrity, detects wear early, and prolongs instrument life.
