Abstract
The utility model discloses a clinic bone grinding device. The clinic bone grinding device comprises a bone grinding device main body and a rod part, wherein the bone grinding device main body is cylindrical, the bottom surface of the bone grinding device main body is provided with a groove, and the top surface of the bone grinding device main body is connected with the rod part; the outer surface of the bone grinding device main body is of an emery structure; the outer diameter of the bone grinding device main body is the same as the diameter of an artificial cochlea implant body, the bottom surface of the bone grinding device main body is provided with the groove for conveniently discharging bone chips, and the rod part is connected with an operation driving device for realizing electric bone grinding and preventing human error situations such as cumbersome and uncontrollable manual bone grinding from happening; the top part of the bone grinding device main body is provided with the groove, the weight of a product can be reduced, and the production cost is reduced. According to the clinic bone grinding device disclosed by the utility model, the accurate grinding of a bone groove can be quickly realized, the size of the bone groove can be matched with the size of the artificial cochlea implant, and the situations that an implant is shifted and a cochlea is damaged or forms a dead space are prevented from happening.
Description
Technical field
This utility model relates to a kind of mill bone object, specifically a kind of for clinical operation, especially the mill bone object of Cochlear Implantation.
Background technology
At present when carrying out Cochlear Implantation, artificial cochlear implant need to embed in the bone groove of patient's skull temples milled, skull temples bone groove first marks after the circle suitable with implant diameter with 1mm corundum conventionally, use respectively the more worn sclerotin of cutting burr and diamond bur, form the bone groove suitable with implant diameter.More than operation is relatively wasted time and energy, due to higher to bone groove dimension precision requirement, very easily occur that bone groove is difficult for the situation tight with implant (titanium body) embedding of cochlea, finally cause implant (titanium body) to be shifted and cochlea damaged or form dead space, the all hematoceles of implant, corresponding hydroderma, necrosis.
In order to address the above problem, those skilled in the art propose to utilize the trepan in osseous surgery to replace cutting burr and the worn sclerotin of diamond bur, it is simpler than above-mentioned operating procedure, but because orthopaedics trepan size function of the prior art is not mated with artificial cochlear implant, the problem of bone groove accuracy to size is not well solved yet.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of clinical mill bone object of using that can disposablely grind the precision bone groove mating with artificial cochlear implant.
To achieve these goals, this utility model adopts following technical scheme:
Clinically with a mill bone object, comprise mill bone object main body and bar portion, described mill bone object main body is cylindrical, and bottom surface is provided with groove, and end face is connected with described bar portion, and the outer surface of described mill bone object main body is corundum structure.
Wherein more preferably, the groove structure of described mill bone object main body bottom surface is circular.
Wherein more preferably, described mill bone object main body upper surface is provided with groove.
Wherein more preferably, described bar portion one end is connected with mill bone object main body, and the other end is the structure that can be connected with operation driving device.
Main body external diameter of the present utility model is identical with artificial cochlea's plant diameter, its bottom surface is provided with groove, can facilitate bone scraps to discharge, and bar portion can be connected with operation driving device, can realize electronic mill bone, avoid the generation of the human error situation such as loaded down with trivial details and uncontrollable of manual mill bone.Surface of the present utility model can adopt corundum structure, can realize fast grinding of precision bone groove, and bone groove size is mated with artificial cochlea implant's size, has avoided implant to be shifted and has made cochlea damage or the situation generation of formation dead space.This utility model is convenient to patient's operation, saves operating time, is conducive to improve success rate of operation, and low production cost of the present utility model, and technique is simple.

The specific embodiment
Embodiment 1
As depicted in figs. 1 and 2, the utility model discloses a kind of clinical mill bone object of using.This is clinical comprises mill bone object main body 1 and bar portion 2 with mill bone object, and mill bone object main body 1 is cylindrical, and bottom surface is provided with groove 11, and recommendation groove is circular configuration.The end face of mill bone object main body 1 is connected with bar portion 2.The outer surface of mill bone object main body 1 is corundum structure.The external diameter of mill bone object main body 1 is 16mm; The internal diameter of groove 11 is 12mm.The degree of depth of groove 11 is 3.5mm.The upper surface of mill bone object main body 1 is provided with end face groove 12, and end face groove 12 degree of depth are 3.5mm.Bar portion 2 one end are connected with mill bone object main body, and the other end is the structure that can be connected with operation driving device.Bar portion 2 external diameters are 2.5mm.The length that bar portion 2 stretches out beyond mill bone object main body 1 is 60mm.
This utility model in use, only need be aimed at the position that need to grind bone groove by mill bone object main body 1, starts operation driving device (being generally drillstock motor), can realize accurate mill bone, and the bone groove size grinding is mated with implant size.
Embodiment 2
In the present embodiment, the external diameter of mill bone object main body 1 is 14mm, and groove internal diameter is 10mm, and depth of groove is 3mm, and bar portion external diameter is 2.45mm, and bar minister degree is 59.5mm.Other structures are with embodiment 1.
Embodiment 3
In the present embodiment, the external diameter of mill bone object main body 1 is 18mm, and groove internal diameter is 14mm, and depth of groove is 4mm, and bar portion external diameter is 2.55mm, and bar minister degree is 60.5mm.Other structures are with embodiment 1.
