An ultrasonic scalpel with the function of preventing aerosol diffusion

Abstract

The invention relates to the field of medical technology, and discloses an ultrasonic knife with the function of preventing gas mist diffusion, including a transducer handle, an ultrasonic knife head, a cushioning mechanism, a processing mechanism and an adjustment mechanism, and the cushioning mechanism is arranged on the ultrasonic knife head Above, the processing mechanism is set on the transducer handle, the adjustment mechanism is set on the processing mechanism, and the cushioning mechanism includes a clamping plate, collar A, collar B and connecting rod A. Through the settings of the cushioning mechanism and the processing mechanism, the During the operation, the blood mist from the incision is extracted, so as to avoid the risk of environmental pollution and virus or bacterial infection caused by the spread of blood mist into the air. Through the setting of the soft tube, the soft tube will maintain its resilience after being deformed by pumping out the air. In this way, the kinetic energy is stored to provide the kinetic energy to generate the negative pressure pumping blood mist in time during the operation, so as to ensure the cleaning effect of the blood mist and avoid the problem that the blood mist cannot be cleared due to the loosening of the switch during the operation.

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
