Abstract
This utility model provides a kind of acetabular bone sander, comprise main body, described main body left end is provided with polishing bulb, described main body right-hand member is provided with jointing, described polishing bulb is connected in main body by expansion link, described body interior is provided with miniature rotary electric machine, described miniature rotary electric machine is arranged on expansion link, drive expansion link by miniature rotary electric machine and then drive polishing bulb to finely tune, described jointing is connected on hand drill, and described expansion link is moved forward and backward by the telescopic cylinder being arranged on its rear end.The rotating speed of the miniature rotary electric machine air exercise abrading-ball head when polishing by expansion link rear end is finely tuned, and drives polishing bulb to move forward and backward by expansion link, prevents operator's hand shaking in moving forward and backward from causing polishing excessive.
Description
Technical field
This utility model relates to medical field, particularly relates to a kind of acetabular bone sander for acetabular bone position of polishing.
Background technology
Hipbone (acetabulum) is synthesized by the body of ilium, seat, shame three bone group.In nest, semi-moon shaped articular surface claims lunate surface (lunate surface).The central authorities of nest do not form the part of articular surface, claim acetabular fossa.The breach of acetabular bone edge lower part claims acetabular notch.Cause acetabular bone to be out of shape due to living habit and cause specific or the problem of hyperosteogeny appears on the body of the mankind, and use the acetabular bone position of acetabular bone sander to hyperosteogeny plasticity of carrying out polishing to be a kind of method solving acetabular bone position hyperosteogeny.Current acetabular bone sander normally installs grinding head additional on hand drill polishes to acetabular bone, but owing to being that manual operation hand drill is polished, controlling hand drill is all by virtue of experience, easily slipping up when polishing, causing malpractice.Therefore, be not easy to control and easily produce polishing excessive problem when solving acetabular bone sander polishing acetabular bone and just seem particularly important.
Utility model content
For above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of acetabular bone sander for acetabular bone position of polishing, the rotating speed of the miniature rotary electric machine air exercise abrading-ball head when polishing by expansion link rear end is finely tuned, and drive polishing bulb to move forward and backward by expansion link, be not easy when solving acetabular bone sander polishing acetabular bone to control and easily produce the excessive problem of polishing.
This utility model provides a kind of acetabular bone sander, comprise main body, described main body left end is provided with polishing bulb, described main body right-hand member is provided with jointing, described polishing bulb is connected in main body by expansion link, described body interior is provided with miniature rotary electric machine, described miniature rotary electric machine is arranged on expansion link, drive expansion link by miniature rotary electric machine and then drive polishing bulb to finely tune, described jointing is connected on hand drill, and described expansion link is moved forward and backward by the telescopic cylinder being arranged on its rear end.
Further improvement is: the junction of described polishing bulb and expansion link is provided with damping spring, and described polishing bulb is arranged in the middle of damping spring by pin.
Further improvement is: be provided with pressure detector in the middle part of described expansion link, is detected the pressure transmitted from polishing bulb by pressure detector.
Further improvement is: described polishing bulb is provided with auxiliary lug, and described auxiliary lug is arranged on the both sides, inside of polishing bulb, and described auxiliary lug is driven by the cylinder being arranged on its rear end and stretches out polishing bulb inside.
The beneficial effects of the utility model are: the rotating speed of the miniature rotary electric machine air exercise abrading-ball head when polishing by expansion link rear end is finely tuned, and drive polishing bulb to move forward and backward by expansion link, prevent operator from causing polishing excessive in movable middle hand shaking, and the pressure be subject to by arranging damping spring and pressure detector air exercise abrading-ball head carries out regulating and reporting to the police, prevent polishing bulb from contacting with acetabular bone portion and excessively cause polishing excess, assist polishing bulb to polish when needed by auxiliary lug, increase work efficiency.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is polishing bulb enlarged diagram of the present utility model.
Wherein: 1-main body, 2-polishes bulb, 3-jointing, 4-expansion link, the miniature rotary electric machine of 5-, 6-telescopic cylinder, 7-damping spring, 8-pin, 9-pressure detector, 10-auxiliary lug, 11-cylinder.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment, only for explaining this utility model, does not form the restriction to this utility model protection domain.
As Fig. 1, shown in 2, present embodiments provide a kind of acetabular bone sander, comprise main body 1, described main body 1 left end is provided with polishing bulb 2, described main body 1 right-hand member is provided with jointing 3, described polishing bulb 2 connects on the body 1 by expansion link 4, described main body 1 inside is provided with miniature rotary electric machine 5, described miniature rotary electric machine 5 is arranged on expansion link 4, drive expansion link 4 by miniature rotary electric machine 5 and then drive polishing bulb 2 to finely tune, described jointing 3 is connected on hand drill, described expansion link 4 is moved forward and backward by the telescopic cylinder 6 being arranged on its rear end.
Further improvement is: described polishing bulb 2 is provided with damping spring 7 with the junction of expansion link 4, and described polishing bulb 2 is arranged in the middle of damping spring 7 by pin 8.
Further improvement is: be provided with pressure detector 9 in the middle part of described expansion link 4, is detected the pressure transmitted from polishing bulb 2 by pressure detector 9.
Further improvement is: described polishing bulb 2 is provided with auxiliary lug 10, and described auxiliary lug 10 is arranged on the both sides, inside of polishing bulb 2, and described auxiliary lug 10 is driven by the cylinder 11 being arranged on its rear end and stretches out polishing bulb 2 inside.
The beneficial effects of the utility model are: finely tuned by the fight each other rotating speed of abrading-ball head 2 of the miniature rotary electric machine 5 of expansion link 4 rear end when polishing, and drive polishing bulb 2 to move forward and backward by expansion link 4, prevent operator from causing polishing excessive in movable middle hand shaking, and undertaken regulating and reporting to the police by arranging damping spring 7 and pressure detector 9 pressure that abrading-ball head 2 is subject to of fighting each other, prevent polishing bulb 2 from contacting with acetabular bone portion and excessively cause polishing excess, assist polishing bulb 2 to polish when needed by auxiliary lug 10, increase work efficiency.
