Combined laparoscope gripper

Abstract

The invention, which mainly relates to the field of medical instruments, discloses a combined laparoscope gripper comprising a detachable gripping head, a rod body and a detachable handle. The rod body and the detachable gripping head and the handle with different functions can be quickly assembled and disassembled, and only the gripping head and the handle with different functions need to be replaced when the gripper is replaced. During an operation, the detachable gripping head can be mounted after the rod body punctures into the abdominal cavity, so that the size, which can reaching3mm or below, of the operating hole is reduced as much as possible; and thus the size of the operating hole diameter only depends on the outer diameter of the rod body and does not depend on the outer diameter of the gripping head. When the combined laparoscope gripper is used for an operation, a rod body puncture hole does not need to be sewn, so that the postoperative pain is slight, and an operation scar can be ignored; and the operation habit of the laparoscopic surgery is the same as that of the traditional laparoscopic instrument, so that medical institutions and doctors who carry out the traditional laparoscopic surgery can use the laparoscopic surgery instrument to carry out surgery without special training, so that the surgical trauma of patients is further reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a combined laparoscope grasper. Background technique [0002] Laparoscopic graspers mainly include laparoscopic separating forceps, intestinal forceps, grasping forceps, titanium clamps, and Hem-o-loc clamp applicators, etc. The above instruments are mainly used for grasping, clamping, separating and Clamping of vascular tissue, etc. When using existing laparoscopic instruments, it is necessary to use trocas of appropriate caliber on tissues such as the abdominal wall or chest wall as a channel for the operation and replacement of corresponding laparoscopic instruments. Troca commonly used calibers are 5mm, 10mm and 12mm. Therefore, when using the above-mentioned conventional laparoscopic instruments for surgery, the abdominal wall or chest wall incision must be able to place the corresponding caliber Troca, so the diameter of the above-mentioned incision should not be less th...

Problems solved by technology

However, because the observation port and the operation port of the single-port laparoscope are located in the same port, the operation triangle cannot be constructed during the operation. Therefore, the original laparoscopic instrument needs to be designed with an angle, which poses a considerable challenge to the design of the single-port laparoscopic instrument. difficulty

These current situations have led to the following situation: 1. Single-port laparoscopic equipment is expensive, and most grassroots medical institutions cannot carry out; 2. Because the traditional operation triangle cannot be constructed during single-port laparoscopic surgery, the special operation triangle constructed by angling instruments can be used for surgery. Those who put forward higher technical requirements, which caused the learning curve of single-port laparoscopic surgery to be significantly longer than traditional laparoscopic surgery, which hindered the promotion of this technology; A larger incision is used to place the Port, and the length of the incision is generally significantly longer than the length of the observation port of a common laparoscope
