Radio knife

Abstract

The invention relates to a radio knife which comprises a knife handle; the front end of the knife handle is provided with a knife head, and the knife handle is internally provided with a catheter the rear end of which is communicated with a flushing pipe and a suction pipe; and the inner walls of the catheter, the flushing pipe and the suction pipe are provided with spiral grooves. The radio knife can realize the functions of the suction pipe and the flushing pipe by the single pipe, has simple structure, and is conveniently switched for use; the radio knife has strong suction force, rapid suction speed and good effect, avoids residual suction matter returning back to the wound when in flushing so as to have good flushing effect, and also can make the actions such as blunt cutting, scraping, poking and the like so as to have rich functions; and furthermore, the radio knife can adjust the suction and flushing range and strength, thus being capable of adapting to the requirements of different operations.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a high-frequency scalpel. Background technique [0002] In the prior art, the scalpel using high-frequency electricity has the functions of electric cutting and electrocoagulation, and cuts, damages and stops bleeding on human tissue through high-frequency electric energy. However, when this kind of scalpel is performing electric cutting, it will generate a lot of smoke, which hinders the sight of medical staff; at the same time, it will generate waste such as tissue debris and blood stains, which need to be washed with water. Patent No. 92219725.3 discloses a multifunctional high-frequency electric scalpel. The handle of the scalpel is integrated with a flushing tube and a suction tube, which are respectively connected to the flushing liquid container and the suction device through flexible hoses. Based on the functions of electrocution and electrocoagulation, it can absorb w...

Patent No. 92219725.3 discloses a multifunctional high-frequency electric scalpel. The handle of the scalpel is integrated with a flushing tube and a suction tube, which are respectively connected with the flushing liquid container and the suction device through flexible hoses. Based on the functions of electrocution and electrocoagulation, it can absorb waste such as smoke, tissue debris, blood stains, etc., and can also wash the wound surface, but the structure of the scalpel is complicated, it is inconvenient to use, and the absorption and washing effect is poor
