Abstract
The invention provides an acetabulum grinder which comprises a body. A grinding bulb is arranged at the left end of the body, a connecting joint is arranged at the right end of the body, and the grinding bulb is connected to the body through a telescopic rod. A miniature rotary motor is arranged inside the body and is arranged on the telescopic rod, and the miniature rotary motor drives the telescopic rod and further drives the grinding bulb to perform fine tuning. The connecting joint is connected to a hand drill, and the telescopic rod can move forwards and backwards through a telescopic air cylinder arranged at the back end of the telescopic rod. In the process of grinding, fine tuning on the rotational speed of the grinding bulb can be achieved through the miniature rotary motor at the back end of the telescopic rod; in addition, the telescopic rod can drive the grinding bulb to move forwards and backwards, so the phenomenon of excessive grinding caused by hand shake of an operator in the process of moving forwards and backwards can be prevented.
Description
Technical field
The present invention relates to medical field, particularly relate 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.
Summary of the invention
For above-mentioned prior art Problems existing, the object of this invention 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.
The invention 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 invention has the beneficial effects as follows: 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.

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 the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
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 invention has the beneficial effects as follows: 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.
