Abstract

The invention discloses a smog-free ultrasound knife. The smog-free ultrasound knife comprises a control device, a suction device, a housing and an ultrasonic knife body. The control device comprises a switch, a power unit and a transmission unit, the power unit is connected with the transmission unit, the switch is electrically connected with the power unit and a negative pressure generator, the suction device comprises the negative pressure generator and a suction part, the negative pressure generator is electrically connected with the control device, the suction device coincides with the axis of the knife bar of the ultrasonic knife body, the inner diameter of the pipe of the suction device is larger than the largest diameter of the outer pipe of the ultrasonic knife body, the suction device is communicated with the negative pressure generator in a sealing manner, one end of the suction device is in transmission connection with the transmission unit to form the seal, the other end of the suction device is in transmission connection with the housing to form the seal, and the suction device is arranged in the housing. During the cutting process of the ultrasonic knife body, the suction device can play a role in cleaning the operation visual field, and the safety and fluency of operations can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a smoke-free ultrasonic scalpel. Background technique [0002] The application of ultrasound usually converts or introduces ultrasound energy into biological tissues through terminal effects or surgical equipment to produce some physiological effects, especially the use of generated heat to cauterize, stop bleeding and cut tissues. In the ultrasonic knife of surgical instruments, the generator generates high-frequency electric energy, and the transducer uses piezoelectric materials or electromagnetically compressed materials to convert high-frequency electric energy into mechanical vibrations, and amplifies the vibrations and transmits them to the end effector. [0003] The shortcomings of the ultrasonic scalpels currently on the market are as follows: 1. When the cutter head performs mechanical vibration to cut tissue at ultrasonic frequencies, high heat will be gene...
