Ultrasonic scalpel with aerosol diffusion prevention function

Abstract

The invention relates to the technical field of medical treatment, and discloses an ultrasonic scalpel with an aerosol diffusion prevention function, wherein the ultrasonic scalpel comprises a transducer handle, an ultrasonic scalpel head, a cushion protection mechanism, a processing mechanism and an adjusting mechanism; the cushion protection mechanism is arranged on the ultrasonic scalpel head,the processing mechanism is arranged on the transducer handle, and the adjusting mechanism is arranged on the processing mechanism; the cushion protection mechanism comprises a clamping plate, a lantern ring A, a lantern ring B and a connecting rod A. By arranging the cushion protection mechanism and the processing mechanism, blood mist bursting out of an incision is extracted in the operation process, and thus the risks of environmental pollution and virus or bacterium infection caused by the fact that the blood mist diffuses into air are avoided. Through the arrangement of a soft cylinder, the soft cylinder can keep resilience force after air is pumped out and deformation is caused, so that kinetic energy is accumulated, negative-pressure air and blood mist pumping is generated in time through kinetic energy when an operation is conducted, the blood mist cleaning effect is guaranteed, and the problem that in the operation process, a switch is loosened, and consequently blood mist cannot be cleaned is solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an ultrasonic knife with the function of preventing gas mist from spreading. Background technique [0002] 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. , has a wide range of applications in the operating room, known as the bloodless scalpel. [0003] During the operation using an ultrasonic scalpel, blood mist or other impurity gas will burst out at the incision when the incision is made. These blood mist not only pollute the environment, but also carry the virus or bacteria that may ex...

Problems solved by technology

[0003] During the operation using an ultrasonic scalpel, blood mist or other impurity gas will burst out at the incision when the incision is made. These blood mist not only pollute the environment, but also carry the virus or bacteria that may exist in the patient's body, leading to viral or bacterial infection Therefore, there is an urgent need for an ultrasonic scalpel with the function of preventing aerosol diffusion to solve the above problems
