Abstract

The invention provides a harmonic knife with a fixing function. The harmonic knife comprises a chuck part, a chuck trigger and a fixing trigger. When a chuck operating part of the chuck trigger is pressed, the chuck part performs clamping actuation, and a tenon of the chuck trigger positioned at a first initial position moves towards a first preset position along a first path. When the fixed operation piece of the fixed trigger is pressed, the push rod of the fixed trigger positioned at the second initial position can move towards the second preset position along the second path, and if the clamping tenon is positioned at the first initial position, the push rod can be interfered to move towards the second preset position. The push rod is provided with a clamping groove, and when the push rod is located at the second preset position, the clamping groove is formed in the first path, and the opening of the clamping groove faces the first preset position, so that when the chuck operating piece is not pressed, the clamping tenon enters the clamping groove from the opening.

Description

technical field [0001] The present invention relates to a harmonic knife. Specifically, the present invention relates to a harmonic knife with a fixed function. Background technique [0002] Harmonic knives are often used in surgical operations to perform actions such as cutting and hemostasis. However, when using a harmonic knife for hemostasis, it is generally through harmonic vibration (eg, ultrasonic oscillation) to directly cut or coagulate tissue or a body part such as a blood vessel or other objects. This method will damage or change biological parts or other objects such as tissues or blood vessels, such as directly cutting and closing blood vessels, etc. Therefore, the implementation still needs to consider the possible effects or consequences after changing or destroying biological parts or other objects. However, in actual surgical operations, temporary hemostasis or fixed actions are often required, and thus the above-mentioned harmonic knife, which can only pe...
