Problems solved by technology

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide an orthopedic instrument to solve the problem of uneven hand force of the medical staff during the process of clamping the bone nail, which makes the fixture structure unstable, resulting in slow and unstable extraction of the bone screw. It will cause the patient to expand the wound, or the wound will continue to deteriorate, which is a kind of harm to the patient, so it is necessary to urgently need an orthopedic device that can safely and effectively remove the internal fixation

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] see Figure 1-Figure 4 , the present invention provides an orthopedic instrument, the structure of which includes a bone extraction device 1, an auxiliary bracket 2, and a base 3. The auxiliary bracket 2 is a rectangular structure and one end is provided with a base 3. One end of the auxiliary bracket 2 and the base 3-phase welding, the other end of the auxiliary bracket 2 is provided with a bone extraction device 1, and the other end of the auxiliary bracket 2 and the bone extraction device 1 adopt an interference fit;

[0025] The bone extraction device 1 is composed of a chute 101, a slide bar 102, an adjustable clamp 103, a limit ring 104, an insertion shaft 105, a threaded rod 106, a driving gear 107, a driven gear 108, a nut 109, and ...

Abstract

The invention discloses an orthopedic instrument. The orthopedic instrument structurally comprises a bone nail pull device, an auxiliary support and a base. In order to achieve the purpose that the orthopedic instrument can clamp bone nails stably and increase the bone nail removal speed, the base is arranged on the auxiliary support, and the bone nail pull device can be assisted through the base;an adjustable clamp is arranged on the bone nail pull device, the bone nail pull device can clamp bone nails with suitable tightness through the adjustable clamp, and it is avoided that bone nails fall off and cause secondary injury to a patient when clamped; the bone nail pull device controls a threaded rod to ascend or descend rapidly through a nut, ascending or descending of the threaded rod can drive a pull rod to move, and the pull rod can pull out bone nails through a fixed clamp. The bone nail pull device can pull out bone nails stably and rapidly, and it is avoided that the patient'swound is expanded or continues to deteriorate.

Description

technical field [0001] The invention is an orthopedic instrument, which belongs to the technical field of medical instruments. Background technique [0002] With the rapid development of orthopedic technology, new internal fixation methods are constantly emerging. New materials and technologies not only effectively restore the stability of bones, but also reduce the damage to bone blood supply and improve the healing rate of fractures. However, there have been more and more difficulties in removing the internal fixation, and the cases of broken nails and plates caused by various reasons are difficult problems for orthopedic surgeons to avoid. For these cases, whether the internal fixation is removed or the internal fixation is reset, the difficult problem of taking out the broken nails is involved. [0003] In the prior art, during the process of clamping the bone nails, the hands of the medical staff are uneven, which makes the structure of the clamp unstable, resulting in...
