Description

Technical Field

[0001] This utility model relates to the field of medical surgical technology, and in particular to a novel laparoscopic surgical forceps handle. Background Technology

[0002] Laparoscopic surgery is increasingly widely used in the field of surgery due to its advantages such as minimal trauma, less bleeding, and less postoperative pain. As a key instrument in laparoscopic surgery, the design and performance of the handles of surgical forceps are crucial.

[0003] Existing surgical forceps handles lack comfort for prolonged gripping. Most handles are not designed with ergonomic principles in mind, resulting in poor fit between the handle shape and the human hand structure, making it difficult to conform to the palm's curve during gripping. Furthermore, the choice of materials does not balance softness and durability, easily causing fatigue and soreness in the surgeon's hand during prolonged gripping, severely affecting the stability and precision of surgical procedures. Additionally, surgical forceps handles are often a one-piece structure. With repeated friction between the handle and the surgeon's hand during long-term, frequent use, coupled with the corrosive effects of multiple sterilization processes, they are prone to wear, damage, or performance degradation. Due to their one-piece design, once wear or damage occurs at the grip area, it cannot be replaced individually. Repair often requires replacing the entire handle, which not only increases medical costs but also temporarily disables surgical instruments, disrupting the normal scheduling and conduct of surgeries. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing surgical forceps handles are one-piece structures, making it impossible to replace the handle separately once it becomes worn or damaged. Repairing them often requires replacing the entire handle, which not only increases medical costs but also causes temporary discontinuation of surgical instruments, affecting the normal scheduling and conduct of surgeries. Therefore, this invention proposes a novel laparoscopic surgical forceps handle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel laparoscopic surgical forceps handle, comprising a fixed handle, one end of which is embedded and fitted with a handle insert, the outer arc wall of the fixed handle having a groove, a movable handle being embedded and connected to a torsion spring inside the groove, the bottom of the fixed handle and the movable handle having a trapezoidal groove and a square groove respectively, the inside of the trapezoidal groove and the square groove having a trapezoidal plate and a square plate respectively, the bottom of the trapezoidal plate and the square plate being fixedly connected to a second hand ring and a first hand ring respectively, the surface of the trapezoidal plate and the square plate having round holes, the inner sidewall of the fixed handle and the movable handle having two hexagonal convex holes, and the outer sidewall of the fixed handle and the movable handle having two convex holes.

[0006] Preferably, a pivot screw is installed between the fixed handle and the movable handle.

[0007] Preferably, the hexagonal convex holes, round holes, and convex holes are aligned with each other.

[0008] Preferably, the hexagonal protrusion and the convex hole are both connected to the square groove and the trapezoidal groove.

[0009] Preferably, the bottom of the first bracelet is fixedly connected to an arc-shaped handle.

[0010] Preferably, the inner arc walls of both the first and second wristbands are fixedly connected with protective pads.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the surgical forceps handle is designed in full accordance with the principles of ergonomics. The shapes of the fixed handle and the movable handle are more in line with the structure of the human hand. The curvature of the first and second hand rings and the position of the arc-shaped handle allow the doctor's hand to be naturally comfortable when gripping, reducing unnecessary stress on the hand muscles. Even if gripping for a long time, it is not easy to cause fatigue and soreness, effectively ensuring the stability and accuracy of surgical operation. At the same time, the surface of the handle is equipped with a protective soft pad. The material is soft and has good elasticity and breathability, which further improves the comfort when holding it, while reducing the friction between the hand and the handle and avoiding abrasion of the hand skin.

[0012] 2. In this utility model, the surgical forceps handle adopts a modular design concept, with the gripping parts (first hand ring, second hand ring, arc-shaped handle, etc.) designed as individually detachable and replaceable components. When these parts become worn or damaged after long-term use and repeated sterilization, it is not necessary to replace the entire handle; only the worn parts need to be replaced, which greatly reduces the cost of using surgical instruments and reduces the waste of medical resources.
