Description

Smoke suction type ultrasonic knife with adjustable handle with suction function Technical Field The invention relates to the technology of medical instruments, in particular to a smoke suction type ultrasonic knife with a suction-adjustable handle. Background The ultrasonic knife is a minimally invasive medical instrument commonly used in clinical surgery, and can accurately cut and coagulate human tissues by converting high-frequency electric signals into high-frequency mechanical vibrations and utilizing vibration energy, so that the ultrasonic knife is widely applied to various endoscope and open surgery due to the characteristics of small surgical wounds, good hemostatic effect and accurate operation, and surgical smoke can be inevitably generated when a knife head and tissues are contacted in the operation. At present, the existing ultrasonic knife has no matched integral smoke suction structure, the smoke generated by the operation is processed by depending on the passive exhaust of a cavity mirror channel or an external aspirator, the external aspirator needs to be matched with an assistant for operation, the problems of delayed response and low suction efficiency exist, the operation is affected by the smoke shielding operation field easily, the cavity mirror environment is polluted, and the scattered operation smoke can cause potential hazard to the health of medical staff. Disclosure of Invention The invention aims to provide a smoke suction type ultrasonic knife with an adjustable suction handle so as to solve the problem that smoke generated in the prior art is easy to influence operation. The smoke suction type ultrasonic knife comprises an ultrasonic knife body, a regulating valve and a control handle, wherein a threaded pipe is arranged in the ultrasonic knife body, a mist suction head is arranged on one side of the threaded pipe, a spring pipe is arranged on the other side of the threaded pipe, the regulating valve is arranged on one side of the spring pipe, the control handle is arranged at the bottom of the ultrasonic knife body, a closing key is arranged on one side of the control handle, a low-grade key is arranged on one side of the control handle at the bottom of the closing key, a middle-high-grade key is arranged on one side of the control handle at the bottom of the low-grade key, a shifting wheel is arranged in the control handle, a transmission gear is arranged on one side of the shifting wheel, a connecting gear is arranged in the control handle at the top of the transmission gear, a limiting gear is arranged in the control handle at the top of the connecting gear, and a movable gear is arranged on one side of the limiting gear. Further, a joint is arranged on one side of the ultrasonic knife body. Further, threads are arranged on the inner side of the joint, and the joint is made of silicone rubber materials. Further, a connecting pipe is arranged on one side of the ultrasonic knife body, and a connector lug is arranged on one side of the ultrasonic knife body at the bottom of the connecting pipe.
