Ultrasonic knife with anti-falling structure

Abstract

The invention relates to an ultrasonic knife with an anti-falling structure, which comprises an ultrasonic knife handle main body and a limiting mechanism, a radio frequency input tube is arranged on one side of the outer wall of the ultrasonic knife handle main body, and a control trigger block is arranged on one side of the lower end of the ultrasonic knife handle main body. Compared with the prior art, the ultrasonic knife has the following beneficial effects that through the arrangement of an anti-falling mechanism, a ball block, a ball groove and a circular ring, when the ultrasonic knife is used, a human hand penetrates through the inner wall of the circular ring, so that the circular ring is located at the wrist of an operator and is movably connected with the wrist, and the spherical ball groove is formed in the upper end of the outer wall of the circular ring; the ball block can rotate at any angle on the inner wall of the ball groove, normal use of equipment is not affected at all, when an operator has an error, the circular ring can limit the ball block at the wrist, loss caused by falling is avoided, the circular ring can also play a certain role in supporting the arm, and energy consumed by the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of medical surgery, in particular to an ultrasonic scalpel with a fall-off prevention structure. Background technique [0002] The ultrasonic scalpel is a high-frequency electrosurgical device, mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and quick postoperative recovery. It acts on human tissue to cut and coagulate, and will not cause side effects such as tissue dryness and burns. There is no current passing through the human body when the cutter head is working. , through the transducer using the electrostrictive effect or magnetostrictive effect, the ultrasonic electric energy is converted into mechanical energy to generate high-frequency vibrations, and through the amplification and coupling of the horn, the cutter head is pushed to work and transmit energy to the local tissues of the human body, the...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of ultrasonic scalpel with anti-falling structure, to solve the existing ultrasonic scalpel proposed in the above-mentioned background technology, when performing medical and surgical operations, all adopt the mode of holding in hand to carry out, and then pass It controls the trigger to activate the ultrasonic scalpel to perform medical operations. Most medical operations last for a long time and have high requirements for the operator's wrist strength, especially for relatively hard operations. Vibration will cause the operator to be more prone to fatigue. Once the operator makes a mistake and the ultrasonic scalpel falls, it will cause irreparable damage to the ultrasonic scalpel, causing a lot of economic damage to the operator and seriously affecting other operators. The problem of the operation efficiency of the ultrasonic scalpel
