Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bone scraper, this device can according to the degree of depth of diseased region, the cooperation degree of depth of adjustable blade flexibly, the length being leant out positive stop strip outside by blade can complete the adjustment scraping the bone degree of depth, meet different demand, this device can be equipped with multiple blade simultaneously, increase and scrape bone efficiency, make to scrape osseous surgery more thorough, avoid the residual of pathogenic agent, this device is easier to hold, and avoids skidding, and can be avoided the muscle and the vascular tissue that destroy diseased region place by knife rest frame.
For solving the problem, the utility model adopts following technical scheme:
A kind of bone scraper, comprise knife rest frame, the internal symmetry of described knife rest frame is provided with the card seat of two or more, described card seat has card groove, it is combined with blade between two symmetrically arranged described card seats, described blade is engaged in described card groove, transition fit between described blade and described card groove, the left side of described knife rest frame is provided with threaded hole, described threaded hole is through to described card groove, locking screw it is combined with in described threaded hole, the side of described locking screw and described blade offsets, the bottom of described blade has blade, the inside of described knife rest frame is provided with positive stop strip, the right-hand member of described knife rest frame has coupling end, it is combined with operating stick in described coupling end, it is combined with screw between described operating stick and described coupling end, described operating stick has handle portion away from that one end of described coupling end, described handle portion and described operating stick are integral type structure.
Preferably, four corner position place arc transition of described knife rest frame outside.
Preferably, described threaded hole is ladder hole, and when described locking screw and described blade offset, the cap portion of described locking screw is positioned at described ladder hole, and described locking screw is interior hexagonal screw.
Preferably, described handle portion is away from the spherical transition in that one end of described operating stick, the outer ring of described handle portion is provided with anti-skidding cover, described anti-skidding cover has interior hole, described anti-skidding tackling is flexible, shrink-fit between described interior hole and described handle portion, and the outside surface of described anti-skidding cover is evenly equipped with anti-skidding particle, described particle and described anti-skidding cover are integral type structure, and the wall thickness of described anti-skidding cover is 1mm-1.5mm.
Preferably, the lower surface arc transition of described positive stop strip.
The beneficial effects of the utility model are: this device can according to the degree of depth of diseased region, the cooperation degree of depth of adjustable blade flexibly, the length being leant out positive stop strip outside by blade can complete the adjustment scraping the bone degree of depth, meet different demand, this device can be equipped with multiple blade simultaneously, increase and scrape bone efficiency, make to scrape osseous surgery more thorough, avoid the residual of pathogenic agent, this device is easier to hold, avoid skidding, the muscle and the vascular tissue that destroy diseased region place can be avoided by knife rest frame, the structure of this device is comparatively simple, cost is comparatively cheap, it is applicable to promoting the use of.
