An ultrasonic scalpel capable of quickly replacing the cutter bar

Abstract

The invention discloses an ultrasonic scalpel capable of quickly replacing a cutter bar, comprising an ultrasonic scalpel body, a control button is installed on one side of the ultrasonic scalpel body, and an external wire is electrically connected to the bottom of the ultrasonic scalpel body, the ultrasonic scalpel body One end is connected with a knife handle bar, and the other end of the knife handle bar is fixedly connected with an ultrasonic transmitter, and a replacement structure is installed between the ultrasonic knife body and the knife handle bar. In the present invention, under the action of the replacement structure, the sleeve can be quickly socketed with the handle rod, and the preset first return spring can drive the T-shaped latch to move downward, and the T-shaped latch can pass through the handle rod The preset jack fixes the handle rod in the sleeve, which is easy to operate. The sleeve can be rotated through the bearing, so that it can drive the handle rod and the ultrasonic transmitter to rotate, and adjust the emission angle of the ultrasonic transmitter. The position is cut, and the connection is stable to prevent the tool handle from falling off.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knife equipment, and particularly relates to an ultrasonic knife that can quickly replace a knife bar. Background technique [0002] Ultrasonic scalpel uses the extremely strong penetrating power of ultrasonic waves to transmit hundreds of high-energy ultrasonic waves through ultrasonic transducers, focusing on the tissue like concentrating solar energy. Ultrasound releases huge energy and quickly converts it into heat energy, instantly making the temperature of the human tissue at the focus reach 70-100°C, and cutting through the ultrasonic transmitter. [0003] In the existing ultrasonic knife, in the process of its use, the two watch shells of the ultrasonic knife are connected and installed by bolts between the knife shank and the ultrasonic knife, which is a cumbersome and time-consuming process, and does not have the function of convenient disassembly and replacement, and The ultrasonic ...
