Since their invention by Dr. Howard Kelly in the 1890s, Kelly forceps have become the most trusted hemostatic clamp in global operating rooms. Used in over 87% of surgical procedures worldwide, these instruments are critical for controlling bleeding, dissecting tissue, and ensuring precision in high-stakes environments. This definitive guide covers every facet of Kelly forceps – from technical specifications and material science to supplier selection and advanced techniques – empowering surgeons, procurement teams, and biomedical engineers with data-driven insights.
| Component | Function | Technical Specification |
|---|---|---|
| Jaws | Vessel occlusion | 1.5-2.5mm serrated gripping surface |
| Ratchet | Locking mechanism | 3-5 tooth configurations |
| Shank | Force distribution | 14-18cm length; 3-5mm thickness |
| Finger Rings | Ergonomic control | 25-30mm diameter |
1895: Dr. Kelly prototypes first "Kelly clamp" at Johns Hopkins
1940s: Tungsten carbide jaw inserts introduced for enhanced grip
2010: ISO 13485 standardization for surgical clamp manufacturing
2023: AI-assisted robotic Kelly forceps enter clinical trials
