Connecting mechanism of ultrasonic scalpel and energy converter and ultrasonic scalpel assembly adopting connecting mechanism

Abstract

The invention discloses a connecting mechanism of an ultrasonic scalpel and an energy converter and an ultrasonic scalpel assembly adopting the connecting mechanism. The connecting mechanism comprisesa tightening rotary disc, a rotary cap and a sleeve structure; and the sleeve structure is hollow and can contain the energy converter and a cable, the surface of the sleeve structure can be detachably connected with a sleeve bag and / or a protective film in a sealed mode, and therefore the sleeve structure can be isolated from the outside through the sleeve bag and / or the protective film, and theenergy converter is prevented from being polluted. According to the mechanism, through the design of the sleeve structure, the repeated sterilization frequency of the energy converter can be reducedwhile the sterile operation requirement is met, the damage of repeated instrument sterilization to an instrument is reduced, and the operation of an operator is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a connection mechanism between an ultrasonic knife and a transducer and an ultrasonic knife assembly using the same. Background technique [0002] In the application technology of the ultrasonic knife, because the ultrasonic knife head and the transducer are of a separate structure, the two are connected by a threaded joint, and the tightening force needs to be controlled within a certain range during the connection, otherwise the ultrasonic knife cannot work normally, and serious can damage the cutter head or transducer. The commonly used fastening method is to add a set of plastic torque wrench. The torque wrench consists of two parts: the knob body and the rotating shaft. During use, the elastic deformation of the plastic on the rotating shaft is pressed by the knob body to control the tightening force. During the operation, the doctor needs to obliquely observe the s...

AI Technical Summary

Problems solved by technology

[0004] (1) Each ultrasonic scalpel is provided with a torque wrench, which increases the cost of the device;

[0005] (2) The torque wrench is installed and removed through the front end of the instrument, which is inconvenient to operate;

[0006] (3) The torque wrench needs to be kept properly during use, otherwise it is easy to lose, which is very inconvenient in use;

[0007] (4) The torque wrench is provided by plastic elastic deformation, the torque value is unstable, and the torque value will become smaller and smaller after repeated use, and the plastic shrapnel is easy to break;

[0008] (5) Since the torque wrench is a separate accessory, it may be forgotten to sterilize the wrench during the disinfection process of the ultrasonic knife, so that the ultrasonic knife cannot be connected according to the set requirements and cause inconvenience

[0010] (7) The position of the button is in the two gears of cutting and coagulation. In the actual doctor's operation, most of the time is selected as cutting, and the symmetrical position is designed, and the feeling of fatigue is strong after long-term use;

Repeated high-temperature sterilization will seriously damage the transducer cables, components, and performance
