Problems solved by technology

The stretching instrument for laparoscopic surgery disclosed in the invention can effectively stretch the abdominal cavity through the four struts at the front end, but when stretching, the tops of the four struts abut against the abdomen, causing discomfort to the human body; in addition, when the instrument is in use, It is necessary for the medical staff to hold the hand grip tightly all the time. Once the four struts are loosened, they will shrink, which is inconvenient to use in laparoscopic surgery.

Abstract

The invention relates to the technical field of medical instruments, and specifically discloses a distraction instrument for laparoscopic surgery. A hand lever is connected to the upper rotation, and a first spring is connected between the hand lever and the inner wall of the rotating groove. The upper end of the hand lever is provided with a pawl, and the upper end of the pawl is provided with an arc-shaped slot. , the upper end of the handle part is connected with an end sleeve; the right end of the end sleeve is connected with a sleeve rod; the distraction instrument for laparoscopic surgery disclosed by the present invention is due to the first arc stay and the second arc The stays are arranged vertically in space, so when they are stretched at the same time, the tissues inside the abdominal cavity can be effectively stretched, which solves the problem of poor stretching effect of existing instruments.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and specifically discloses a distraction instrument for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method. It is currently a relatively advanced surgical treatment method and can treat many types of diseases. As an advanced minimally invasive technique, laparoscopic surgery has been widely used in clinical practice due to its small trauma, less bleeding, and rapid postoperative recovery. When performing laparoscopic surgery, a micro-incision is made on the patient's abdomen first, and the laparoscope is inserted into the patient's abdominal cavity through the micro-incision. The lens of the laparoscope can provide the doctor with a wider and clearer view. However, the tissues in the patient's abdomen It is easy to block the lens of the laparoscope and limit the operation space. Generally, support structures such as...
