Abstract
The utility model discloses a bone scraping device for cervical vertebra and lumbar vertebra in a bone surgery appliance. The bone scraping device comprises a tool bar, a bone scraping tool bit, a hollow jacket, an eccentric sleeve, a locking nut and a rapid assembly handle, wherein the bone scraping tool bit is fixed at the top end of the tool bar; the eccentric sleeve is integrally fixed inside the jacket; the tool bar and the bone scraping tool bit are arranged inside the jacket, and move along the eccentric sleeve; the tail end of the jacket is provided with a locking screw hole which passes through the jacket and an eccentric sleeve wall; the locking nut is matched with the locking screw hole; and the rapid assembly handle is fixed together with the tail end of the tool bar, and is used for driving the tool bar to rotate. The bone scraping range of the tool bit of the bone scraping device is expanded by using the principle of eccentric shaft rotation under the condition of small hole insertion, the entire bone scraping device is easy and convenient to manufacture and use, the cost of a surgery appliance is reduced, and waste is avoided; and meanwhile, the surgery time is saved.
Description
Technical field
This utility model relates to the technical field of bone surgery set, is specifically to be used for the bone object of scraping of cervical vertebra and lumbar vertebra in a kind of bone surgery set that can remove up hill and dale disc tissue, hypertrophy calcified tissue and apophysis.
Background technology
Transformation along with the raising of people's living standard and people's working environment, working method, between cervical spondylosis, lumbar vertebra, the disease such as other outstanding becomes disease common in Orthopedic Clinical, operation can be removed Lumbar intervertebral disc protrusion tissue, the hypertrophy calcified tissue of pressuring nerve, and the large hyperosteogeny that has of front road or way of escape length, thereby to guarantee that fusion device and terminal plate of vertebral body have best engaging to guarantee that fusion device implants stable.
The utility model content
The technical problems to be solved in the utility model is to provide the bone object of scraping that is used for cervical vertebra and lumbar vertebra in a kind of bone surgery set that can remove up hill and dale disc tissue, hypertrophy calcified tissue and apophysis.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Be used for the bone object of scraping of cervical vertebra and lumbar vertebra in bone surgery set of the present utility model, comprise: knife bar and be fixed on the xyster head on knife bar top; Hollow overcoat and one are fixed on the eccentric bushing of overcoat inside, and knife bar and xyster head are arranged on the inside of overcoat and move along the eccentric bushing direction, and the locking screw holes of perforation overcoat and eccentric jacket wall is set at the end of overcoat; The locking nut that matches with above-mentioned locking screw holes; Fix and drive with the knife bar end quick-mounting handle that knife bar rotates.
This utility model can also adopt following technical measures:
The rotation external diameter of described xyster head is greater than the external diameter of knife bar overcoat.
Described locking nut is with knife bar and eccentric bushing locking, and the knife bar after locking rotates around eccentric shaft.
Advantage and the good effect that the utlity model has are:
the bone object of scraping that is used for cervical vertebra and lumbar vertebra in bone surgery set of the present utility model, cutter head is to screw in overcoat in the intervertebral space process, swivel knife carrier before scraping the bone object intervertebral to scrape bone, until cutter head stretches into overcoat when outer, the locking nut of tightening overcoat one end is fixed together knife bar and eccentric bushing, at this moment the quick-mounting handle that rotation coordinates with knife bar is scraped bone, the bone scope of scraping that this utility model utilizes the rotation eccentric axis principle to enlarge in aperture insertion situation to scrape the bone object cutter head, the whole structure fabrication of scraping bone object and easy to use, reduced the cost of operating theater instruments, avoided waste, saved simultaneously operating time.
