Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a needle-knife device. The needle knife device comprises a knife body, a handle and a detection assembly; a developing structure is arranged on the outer side face of the knife body, a first channel is formed in the knife body, a second channel is formed in the handle, the knife body is partially installed in the second channel, the detection assembly comprises a probe, a positioning cap and an electrode wire, and at least part of the probe penetrates through the second channel and the first channel. The end, away from the scalpel body, of the handle is detachably connected with the positioning cap, one end of the probe is connected to the positioning cap and connected with the electrode wire, and the other end of the probe extends out of the first channel. By using the needle-knife device in the technical scheme, the functions of nerve stimulation and recognition, ultrasonic development, cutting, liquid medicine supply and the like are integrated, a basis is provided for safety, high efficiency and convenience of surgical operation, and meanwhile the operability and convenience of the needle-knife device are improved through cooperation of the components.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a needle-knife device. Background technique [0002] The needle-knife instrument for nerves is a medical device used for subcutaneous or deep muscle cutting of the human body. [0003] Generally, the cutting operation during surgery is performed through the knife body of the needle-knife instrument, during which it is also necessary to add medicinal liquid through the medicine supply element for auxiliary treatment. In some specific cases, it is also necessary to connect a developing device for ultrasonic imaging. At the same time, in order to ensure the safety of surgical treatment, stimulating electrodes will be added to determine the location of the nerve, which is convenient for avoiding during the surgical operation. [0004] The prior art can only realize a single function or a small number of needle-knife instrument functions combined, and cannot re...
