Stripping guiding device for orthopedic surgery

Abstract

The invention discloses a stripping guiding device for an orthopedic surgery. The device comprises a handle, a guiding rod and a guiding wire; the handle comprises a wide handle part, a guiding part and a bending part, and the guiding part is provided with a penetrating hole and / or a penetrating groove used for the guiding wire to penetrate from the wide handle part out of a free end; a blunt endis arranged at the front end of the guiding rod and is in threaded connection with the free end of the guiding part; the handle is provided with a guiding groove used for the guiding rod to penetratethrough and cooperative with a fixed groove. The device is applicable to the stripping of muscle tissue, nerve and blood vessels and the penetrating and guiding of the guiding wire and a lead line tobundle or fix bone blocks and ligaments. The bending part of the device can effectively prevent that in the stripping process, the muscle tissue is injured, the thickness of the handle is reduced as far as possible on the basis of ensuring the guiding wire to normally penetrate, and especially the guiding groove formed in the inner surface of the handle has the reinforcing rib effect to improve the strength of a stress point of the handle.

Description

technical field [0001] The invention relates to a surgical auxiliary device in the field of medical devices, in particular to a stripping guide device for orthopedic surgery. Background technique [0002] In orthopedic surgery, it is often applied to the situation where it is necessary to bind the bone with a needle guide cable or to fix the insertion point of the ligament and tendon, which plays an important role in maintaining the mechanical stability of the bone and the motor function of the tendon. Some of the current guiding and winding methods are simple and rude, which cause great damage to the periosteum tissue and lack protection measures for important blood vessel and nerve tissues. Existing auxiliary devices lack separation and protection for surgically separated muscles, nerves, and vascular tissues, which can easily cause damage; some threading and threading devices are three-dimensional stent structures, which are too complicated and heavy, which is not conduci...
