Description

Technical Field

[0001] This utility model belongs to the field of medical surgical forceps design and manufacturing technology, and specifically relates to a medical surgical forceps with antibacterial and friction-reducing effects. Background Technology

[0002] Surgical forceps are commonly used surgical instruments, widely applied in skin incision and surgical suturing, and are typically made of stainless steel or other metal materials. Minimally invasive surgery offers significant advantages in reducing patient pain and bleeding; however, current surgical forceps are prone to tearing when cutting or separating tissue. Sharp cutting edges and minimal friction are crucial for rapid cutting and separation of skin tissue, reducing bleeding and alleviating patient pain. Furthermore, surgical forceps, due to their prolonged contact with skin tissue after repeated use, must possess excellent antibacterial properties. Therefore, improving the sharpness, friction-reducing properties, and antibacterial performance of surgical forceps is of paramount importance.

[0003] To address the aforementioned issues, Chinese patent application number 201320221551.1 reports a nano-ta-C coated surgical scalpel. This scalpel has a ta-C coating deposited on its surface, increasing its sharpness, improving its wear resistance, and reducing patient discomfort. Chinese patent application number 202421057305.1 reports a surgical forceps that increases surgical stability, reduces unnecessary surgical damage, and extends the forceps' lifespan. However, these technologies do not simultaneously address friction reduction and antibacterial effects. Therefore, designing and developing medical surgical forceps with both antibacterial and friction-reducing properties is of significant importance. Utility Model Content

[0004] Objective: The purpose of this invention is to overcome the shortcomings of the prior art and provide a medical surgical forceps with antibacterial and friction-reducing effects. This surgical forceps can achieve sharp tissue cutting, has good friction-reducing effect on the cutting edge, and also has antibacterial properties.

[0005] Technical solution: The present invention provides a medical surgical forceps with antibacterial and friction-reducing effects. The cutting edge of the surgical forceps has a multi-tooth structure (1), the surface of the multi-tooth (1) has a dovetail-shaped microgroove texture (2), and the surface of the multi-tooth (1) has a single crystal diamond coating (3) and an AgVTeC coating (4).

[0006] The medical surgical forceps described herein have antibacterial and friction-reducing effects, wherein the cone angle θ1 (11) of the multi-toothed tooth (1) is 10-45°, and the cone angle θ2 (21) of the dovetail-groove microgroove texture (2) is 2-20°.

[0007] The medical surgical forceps described herein have antibacterial and friction-reducing effects, wherein the height of the multi-toothed tooth (1) is 50-500 μm.

[0008] The medical surgical forceps described herein have antibacterial and friction-reducing effects, wherein the thickness of the single-crystal diamond coating (3) is 0.01μm-10μm, and the thickness of the AgVTeC coating (4) is 0.01μm-10μm.

[0009] The beneficial effects of this utility model are as follows: 1. The surgical forceps blade designed in this utility model has a micron-level multi-tooth structure, which can achieve sharp cutting of tissues; 2. The dovetail-shaped microgroove texture on the surface of the multi-tooth has the function of self-transporting tissue fluid. During the tissue cutting process, the tissue fluid is transported along the microgroove texture, forming a lubricating film at the interface between the tissue and the blade, thereby enhancing lubrication and reducing friction; 3. The surface of the multi-tooth has a single-crystal diamond coating and an AgVTeC coating, which can enhance antibacterial properties, reduce friction, and improve the wear resistance and corrosion resistance of the surgical forceps blade.
