Splicable multi-angle needle inserting external fixator

Abstract

The invention provides a splicable multi-angle needle inserting external fixator comprising a first sliding rod, an adjusting block, a second sliding rod, a sliding block, a needle fixing block and a half needle; one end of the first sliding rod is connected with the side wall of the adjusting block, a hemispherical groove is formed in the adjusting block, the side, away from the first sliding rod, of the hemispherical groove is provided with an opening, one end of the second sliding rod is connected with a ball, and the ball is movably clamped into the hemispherical groove; the end, away from the adjusting block, of the first sliding rod penetrates through the sliding block, and one end of the sliding block is of an arc-shaped structure; the needle fixing block is connected with the end, of the arc-shaped structure, of the sliding block, a long circular through hole is formed in the needle fixing block in a penetrating mode from top to bottom, and a half needle penetrates through the long circular through hole and is sleeved with a fixing ring sleeve; and the side, close to the sliding block, of the fixing ring sleeve is rotationally connected with the inner wall of the long circular through hole. According to the splicable multi-angle needle inserting external fixator, the direction of the half needle can be doubly adjusted, the position of the half needle can be adjusted, the adjusting range is widened, and the device can be detached and is convenient to use.

Description

technical field [0001] The invention mainly relates to the technical field of medical devices, in particular to an external fixator capable of splicing multi-angle needle insertion. Background technique [0002] Needle insertion (inner needle), one of the acupuncture techniques, is the method of inserting the filiform needle into the body. In terms of operation, preparatory techniques such as following the meridians and pressing the acupoints are generally used, and then the needle is inserted into the predetermined depth from shallow to deep, usually using half a needle. The half-needle is widely used in the fixation of bones in surgical operations. The half-needle for orthopedic medical external fixation in the present technology is generally fixed by a common clamping pin connecting column and a fixing nut connected at its bottom. [0003] For example, the patent application whose application number is CN201520013708.0 includes a clamping block body, the top of the clamp...

AI Technical Summary

Problems solved by technology

Although the angle and direction of the half-needle can be adjusted, the adjustment is still limited, and the device is fixed, which is not easy to disassemble, and the practicability is low
