Electric screw tap

Abstract

The invention relates to the technical field of medical equipment, and discloses an electric screw tap. The electric screw tap comprises a handle, a screw tap body, a detection assembly and an auxiliary part. The screw tap body rotationally penetrates through the handle, spiral teeth are arranged on the side wall of the far end of the screw tap body, a plurality of scale marks are arranged on the side wall of the near end side of the spiral teeth, the screw tap body comprises a first contact part and a second contact part which are in insulated connection, and the first contact part and the second contact part both extend to the far end of the screw tap body; the detection assembly comprises a current acquisition piece, a first acquisition end of the current acquisition piece is electrically connected with the first contact part, and a second acquisition end of the current acquisition piece is electrically connected with the second contact part; the screw tap body is connected to the auxiliary part in an insulating mode and covers at least part of the side wall of the screw tap body, and the auxiliary part can move in the axial direction of the screw tap body. According to the invention, the operation time is shortened, the working intensity of doctors is reduced, the contact between the screw tap and the tissue during the operation is monitored at any time, and the operation safety and the operation effect are ensured.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electric wire tap. Background technique [0002] In orthopedic surgery, the fixation of the bone is achieved by means of screws. Generally, a blind hole is drilled first, then the drilled blind hole is tapped to form a threaded hole, and finally the screw is screwed into the threaded hole for fixing. Usually the depth of the blind hole is less than the depth of the final threaded hole, that is, the tap needs to further tap forward along the axis of the blind hole at the blind hole to increase the hole depth. [0003] Since the tapping during the operation is not a visual operation, the doctor determines the depth of the threaded hole through experience and X-ray irradiation. Soft tissue or nerve damage, ranging from bleeding to paralysis or movement disorders. At the same time, after tapping a certain depth, it is necessary to measure the depth of the threaded hol...

AI Technical Summary

Problems solved by technology

[0004] Using the wire tap of the prior art, the operation time is longer, the efficiency is low, the work intensity of the doctor is high, and the exposure times of the doctor and the patient under the X-ray are relatively small many

In addition, judging when to stop the feeding of the wire tap only by the doctor's hand feeling experience has a great influence on subjective factors, which cannot guarantee the effect of the operation, and may easily cause secondary injury to the patient.
