Introduction
In surgical procedures, optimal healing versus visible scarring often comes down to forceps selection during tissue manipulation and closure. The wrong forceps can cause tissue crushing, trauma, and compromised wound edge integrity that technique alone cannot overcome.
Selecting the right toothed suture forceps directly impacts surgical precision, tissue trauma, procedure time, and patient outcomes including scarring and healing time.
Studies indicate that properly selected toothed forceps allow surgeons to maintain secure tissue grip with significantly lower applied pressure than smooth forceps. This reduces crush injuries and ischemia that lead to wound complications.
TL;DR
- Toothed forceps use interlocking teeth for secure grip with less tissue crush than smooth forceps
- Common patterns: 1x2 rat tooth (dense tissue), 2x3 (fibrous), Adson (skin), DeBakey (vascular)
- Choose based on tissue density, procedure complexity, grip control, and sterilization needs
- Minimize tissue grasps—repeated manipulation causes injury with any forceps type
What are Toothed Suture Forceps?
Tissue handling during suturing demands precision—too much force crushes delicate tissue, too little allows slippage during needle placement. Toothed suture forceps address this challenge through interlocking teeth at the tip that provide secure grip without excessive compression.
Unlike smooth forceps that rely on friction alone, toothed variants use a mechanical "bite" to stabilize tissue with less crushing force.
Primary functions include:
- Tissue manipulation during dissection and wound preparation
- Suture needle handling for safe, controlled placement
- Wound edge stabilization during closure procedures
- Controlled retraction to improve surgical field exposure
The key difference lies in the gripping mechanism. Toothed forceps use mechanical interlock to stabilize tissue, allowing surgeons to maintain secure holds with less crushing force compared to smooth forceps, which require higher compression to prevent slippage.
This makes toothed variants preferred for traditional suture-based closures when firm grip is essential. While forceps remain standard in many surgical settings, modern closure technologies—including bioabsorbable stapling systems—offer alternatives that reduce closure time while maintaining tissue integrity.
Anatomy of Toothed Suture Forceps: Core Components
Understanding forceps anatomy helps surgeons select instruments that offer optimal control and reduce hand fatigue during lengthy procedures. Each component directly impacts surgical precision and surgeon comfort.
Tip Configuration and Tooth Pattern
The tip houses the interlocking teeth, with configurations designed for different tissue densities and grip requirements:
- 1x2 (single tooth): Concentrates grip at specific points for precise tissue handling
- 2x3 (multiple teeth): Distributes force more broadly across tissue surfaces
- 3x4 (multiple teeth): Provides maximum grip distribution for secure tissue control
The tooth pattern determines how gripping force is applied, with single-tooth designs offering precision and multi-tooth patterns providing broader force distribution.
Handle Design and Grip Surface
Handle ergonomics—including straight vs. curved profiles, textured vs. smooth surfaces, and overall length—affect grip control, precision, and surgeon fatigue during extended procedures.
Professional-grade forceps feature specific handle designs, such as the broad, flat handles of Adson forceps, to improve grip stability and control.
Studies show that novice surgeons typically exert 22.7% more force than experts, making ergonomic design critical for reducing unnecessary tissue trauma. These considerations extend to the forceps' overall dimensions.
Overall Length and Weight Distribution
Forceps length typically ranges from 4-7 inches for general surgery, with weight balance influencing control, especially in deep cavities or minimally invasive operations.
Common lengths range from 120 mm (approximately 4.75 inches) for delicate Adson models to 160 mm (6.25 inches) for standard anatomical forceps. Proper length selection impacts surgical precision and reduces hand strain during lengthy procedures.

Tooth pattern selection is the most critical factor in forceps performance. Different configurations distribute gripping force differently across tissue surfaces, directly affecting tissue trauma and grip security.
1x2 Tooth Pattern (Rat Tooth)
This single-tooth design—one tooth opposing two teeth—provides concentrated grip with minimal tissue compression.
Key characteristics:
- Ideal for delicate tissues like skin edges, fascia, and peritoneum
- Standard for dense tissue like fascia, providing secure hold on structures requiring firm stabilization
- Prevents slippage during suturing through concentrated grip
- Creates focal puncture points, requiring precise placement
2x3 Tooth Pattern
This multiple-tooth configuration—two teeth opposing three teeth—distributes grip force across a broader surface area. It suits tougher tissues like muscle, tendon, and dense connective tissue.
The 2x3 pattern reduces slippage on fibrous tissues while maintaining controlled pressure. The broader tooth distribution prevents tearing in tissues that might fail under single-point loads, offering versatility for intermediate-density structures.
Adson Forceps (Fine Toothed)
Adson forceps feature very fine, closely-spaced teeth designed for delicate tissue manipulation in plastic surgery, facial procedures, and microsurgery where minimal trauma is essential.
Fine-toothed Adson forceps are the "workhorse" for cutaneous closure, with small interlocking teeth allowing eversion of skin edges with minimal crush injury. The 1x2 fine configuration provides secure grip without the aggressive penetration of larger rat-tooth patterns.
DeBakey Forceps (Atraumatic Teeth)
DeBakey forceps feature unique longitudinal serrations rather than traditional teeth, providing secure grip on vascular and visceral tissues without puncturing or crushing.
DeBakey forceps are considered atraumatic and designed specifically for soft tissue and vessels. The fine serrated pattern avoids the penetrating trauma associated with rat-tooth configurations, which proves essential for cardiovascular and thoracic procedures where tissue integrity is critical.
What to Consider When Choosing Toothed Suture Forceps
Selecting optimal toothed forceps requires matching instrument characteristics to tissue type, procedure complexity, and surgical technique preferences. The following factors help surgical teams connect technical specifications to measurable outcomes like reduced tissue trauma, faster procedure times, and improved healing.
Tissue Type and Density
Tissue characteristics—delicate skin vs. dense fascia vs. vascular structures—dictate tooth pattern selection.
Selection guidelines by tissue type:
- Dense fascia/linea alba: 1x2 rat-tooth for secure hold without slippage
- Skin edges: Adson fine-toothed (1x2) for eversion with minimal trauma
- Superficial delicate tissue: Brown-Adson (7x7) for distributed grip
- Vascular/visceral structures: DeBakey serrations for atraumatic handling
Crushing skin edges with improper forceps leads to ischemia, which is directly linked to increased infection rates and wound dehiscence. Proper tooth pattern selection reduces tissue trauma scores, shortens healing time, and lowers complication rates.
Procedure Type and Surgical Access
Procedure complexity—open vs. laparoscopic, superficial vs. deep cavity—determines optimal forceps length, tip angulation, and handle design.
Length selection by procedure:
- Minimally invasive/superficial: 120mm forceps for better control in confined spaces
- Deep cavity access: 160mm instruments for adequate reach
- Laparoscopic procedures: Specialized lengths matching port requirements
Proper length selection improves surgical precision and reduces hand fatigue during lengthy procedures.
Grip Control and Tactile Feedback
The standard accepted technique is the "pencil grip" between thumb and index finger, allowing fine motor control and precise manipulation. Forceps must provide sufficient grip security without requiring excessive closing force.
Key grip considerations:
- Adequate grip security without excessive closing force
- Reduced hand fatigue during extended procedures
- Enhanced fine motor control for precise tissue manipulation
- Lower risk of needle stick injuries from tissue slippage
Sterilization Compatibility and Durability
Material considerations—stainless steel grades, titanium alloys, carbide-tipped teeth—affect instrument longevity, sterilization cycle tolerance, and maintenance requirements.
Common material standards:
- Stainless steel: Governed by ISO 7153-1 and ASTM F899 for corrosion resistance and hardness
- Titanium Grade 5: Ti-6Al-4V compliant with ASTM F136 and ISO 5832-3 for superior strength-to-weight ratios
- Tungsten carbide inserts: Enhanced grip durability and extended lifespan
Most forceps are compatible with steam sterilization at 134°C for 3+ minutes. Durability impacts long-term cost-effectiveness and consistent performance across multiple procedures.
Ergonomics and Surgeon Preference
Handle design, weight balance, and grip texture significantly affect surgeon comfort during extended procedures, with ergonomic forceps reducing hand strain and improving precision.
Surgeon preferences—pencil grip vs. palmar grip—influence optimal forceps selection. Surgeons should generally avoid palmar grips for suturing, as they limit dexterity and often result in excessive force application.
Integration with Closure Technique
Forceps selection should match the chosen closure method—traditional sutures, subcuticular closure, metal staples, or bioabsorbable closure systems—to optimize tissue handling and final cosmetic outcomes.
Guidelines emphasize minimizing the number of times skin is grasped, as multiple unnecessary grasps with either toothed or non-toothed forceps result in traumatic injury. Modern closure innovations, including bioabsorbable stapler systems that eliminate the need for traditional suture manipulation, require forceps techniques that minimize tissue handling and preserve wound edge integrity.
How SubQ It! Complements Precision Forceps Technique
Toothed forceps remain essential for tissue manipulation, but the closure method you choose directly impacts how much forceps handling is required. SubQ It!'s bioabsorbable closure system works with proper forceps technique to reduce overall tissue manipulation time.
The system eliminates percutaneous staples, reducing tissue trauma that even skilled forceps technique cannot avoid with traditional closures. Because the external skin is never pierced, train-track scarring from metal staples is eliminated entirely.
Key advantages for forceps-dependent procedures:
- Closures complete 7X faster than manual sutures (7 seconds vs. 42 seconds per fastener)
- More time available for precise tissue positioning with Adson forceps during setup
- Reduced repetitive forceps manipulation during closure phase
- Superior cosmetic outcomes without extensive tissue handling
This efficiency shifts focus to optimal tissue positioning at the start, then enables rapid closure without the extended manipulation manual suturing requires.
Conclusion
Selecting the right toothed suture forceps is not about choosing the most expensive or popular instrument, but rather matching tooth pattern, grip characteristics, and ergonomics to specific tissue types and surgical techniques.
The 1x2 rat-tooth pattern excels for dense fascia, Adson fine-toothed forceps remain the standard for skin closure, and DeBakey serrations provide atraumatic handling for vascular structures.
Forceps performance should be evaluated periodically for tooth wear, alignment issues, and grip degradation.
While traditional forceps remain essential for tissue handling, closure innovations like SubQ It!'s bioabsorbable stapling systems complement precise forceps technique—delivering faster procedures, reduced tissue trauma, and superior healing with minimal scarring.
Frequently Asked Questions
What are suture forceps called?
Suture forceps are also called tissue forceps, thumb forceps, or pickup forceps. Specific types are named after their designers (Adson, DeBakey) or tooth configurations (rat tooth forceps for 1x2 pattern).
What are forceps 4 uses?
The four primary uses are grasping tissue during dissection, stabilizing wound edges during suturing, handling suture needles safely to prevent needle stick injuries, and retracting tissue to improve surgical field exposure.
What are the two types of forceps?
The two main categories are toothed forceps with interlocking teeth for secure tissue grip, and non-toothed forceps with smooth or serrated tips for handling delicate structures. Toothed forceps use mechanical bite, while smooth forceps rely on friction.
What is the difference between toothed and non-toothed forceps?
Toothed forceps have interlocking teeth that penetrate tissue slightly for secure grip without crushing, while non-toothed forceps use smooth surfaces for delicate tissues that would be damaged by teeth. Toothed forceps require less closing force, reducing compression trauma.
How do you hold suture forceps properly?
Use the pencil grip where forceps are held between thumb and first two fingers like a pencil. This allows precise control and reduces hand fatigue during extended procedures.
What tooth pattern is best for delicate tissue?
The 1x2 (rat tooth) or Adson fine-toothed patterns are optimal for delicate tissues like skin edges and fascia. They provide secure grip with minimal trauma, making them ideal for cosmetically sensitive areas.
