Length-adjustable endoscopic electric scalpel

Abstract

The invention relates to a length-adjustable endoscopic electric scalpel. The scalpel comprises a first mounting shell, a connecting plate, a second mounting shell, a first connecting table, a third mounting shell, a second connecting table, an electric knife, a moving plate, a cold light lamp, a camera, a start-stop switch and a connecting wire; the outer profiles of the cross section of the first mounting shell, the connecting plate, the second mounting shell, the first connecting table, the third mounting shell and the second connecting table are all flat oval; two stepped holes are arranged on the second connecting table; the cold light lamp and the camera are respectively arranged in the two stepped holes; the electric knife is connected to the moving plate; a driving mechanism for driving the moving plate to move is arranged in the first mounting shell and the second mounting shell; and the connecting wire is electrically connected to the cold light lamp and the camera respectively. The scalpel has wide application range, a doctor can flexibly adjust the corresponding extension length of the electric knife according to the type of the operation, the section of an area held bythe doctor is flat oval, the doctor holds the scalpel more conveniently, the operation comfort is good, and the operation accuracy of the doctor is further improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscopic electric scalpel with adjustable length. Background technique [0002] Laparoscopic surgery is a type of surgery that uses high-tech methods. Compared with traditional surgical methods, it can perform surgery through smaller incisions, and causes less damage to tissues than traditional surgical operations. Through the keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. The surgeon guides the operation of the surgical instrument to perform the operation through the images transmitted to the monitor. This type of surgery is called laparoscopic surgery when performed in the abdomen, arthroscopic surgery when performed in the joints, and thoracoscopic surgery when performed in the chest cavity. [0003] For different types of endoscopic surgery, the length of the electric knife required by the doctor to perfor...

AI Technical Summary

Problems solved by technology

[0003] For different types of endoscopic surgery, the length of the electric knife required by the doctor to perform the operation is different. The length of the existing electric knife is fixed. One kind of electric knife can only be used for one kind of operation, and the scope of use is small and has certain limitations. Moreover, The handle of the existing electrosurgical knife is generally cylindrical, and the doctor's grip is not comfortable, which affects the accuracy of the operation
