Ultrasonic scalpel with function of preventing aerosol diffusion

Abstract

The invention discloses an ultrasonic scalpel with the function of preventing gas mist diffusion, which belongs to the technical field of medical devices, and its technical solution includes a handle, an ultrasonic transducer, an outer tube and an ultrasonic conduction rod, and the outer tube is detachably arranged on the handle On one side of the handle, the ultrasonic transducer is detachably arranged on the other side of the handle, the ultrasonic conduction rod is arranged inside the outer tube, and one end of the ultrasonic conduction rod is connected to the output end of the ultrasonic transducer connected, the end of the outer tube away from the handle is also provided with a cutter head connected to the ultrasonic conduction rod, the inside of the handle is provided with a smoke detection module, and the surface of the outer tube is close to the side of the cutter head There is a suction port, and the inside of the outer tube is also provided with a suction pipe connected to the suction port. The present invention is convenient for cleaning the probe, so that the sensor can detect smoke with higher accuracy, and avoid the error of the ultrasonic knife in the non-working state. Inhale.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more particularly, to an ultrasonic knife with the function of preventing the diffusion of aerosols. Background technique [0002] With the rapid development of modern medicine, the ultrasonic knife has been widely used in clinical surgical treatment. The ultrasonic knife is an ultrasonic wave that can cut the internal tissue of the human body like a real knife by using the principle of ultrasonic. The ultrasonic knife is mainly composed of the main engine, the driving handle and the connecting line, the cutter head and the foot switch. The electric energy is converted into mechanical energy by the driving handle and output to the cutter head. The cutter head further amplifies this vibration and performs mechanical vibration, which causes water vaporization in tissue cells, protein hydrogen bond breakage, cell disintegration, tissue incision or coagulation, thereby To achieve...

Problems solved by technology

[0003] During the cutting process of the ultrasonic knife, smoke will be generated, which will hinder the user's vision and affect the accuracy of the operation. Therefore, there are ultrasonic scalpels that absorb smoke on the market. For pumping, because the outer tube of the ultrasonic knife is generally thin, the sensor is mostly installed inside the handle. However, in the actual detection process, once the smoke is too large, it is easy to cause the sensor to be blocked, or too much impurities are accumulated inside the sensor. After repeated use, it is easy to affect the accuracy of the sensor in detecting smoke, causing the ultrasonic knife to misjudge and inhale in the non-working state
