Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, the detachable automatic centering formula ring-type of the present invention takes bone drill, including circular hollow drill bit 1, connecting portion 3, the heart is bored 4 and the ring-type brill handle 2 being connected with rotating driving device, band saw dentation blade it is provided with in the front end of circular hollow drill bit 1, the rear end of circular hollow drill bit 1 is connected with one end of connecting portion 3, the other end of connecting portion 3 bores handle 2 with ring-type and is connected, the heart bores 4 include boring handle 42 to heart drill bit with to the heart, the rear end that the heart bores 4 drill bits is connected with to heart brill handle 42, the heart is bored handle 42 and is detachably arranged on connecting portion 3, the heart is bored the axis of axis and circular hollow drill bit 1 of 4 on same straight line, the heart is bored 4 chisel edges and in outside, circular hollow drill bit 1 front end or the heart is bored 4 front ends with circular hollow drill bit 1 front end at grade。
The heart is bored 4 design with circular hollow drill bit 1 concentric bore, it is ensured that the thickness of ring-type bone and center；Design for disassembly, can dismantle internal to heart brill 4 after ensureing concentric locating, and the endoporus being drilled can play centralized positioning effect。
As shown in Figure 4, Figure 5, it can be some drill bit 41, fluted drill drill bit 43 or cortical bone drill bit that the heart bores 4 drill bits。
The heart boring handle 43 and rotates the footstalk bar portion of apparatus for standard dental, corresponding connecting portion 3 is bore, with to the heart, the standard cell phone connection handle that handle matches。The heart is bored the standard dental that handle 43 is standard GB/T 5046.1-85 defined and rotates the footstalk bar portion of apparatus。The standardized design of connecting portion 3 can install multiple brill, fluted drill or cortex bone drill, improves the range of application of the present invention。Multiple drill bit can be changed in the process used。
As it is shown on figure 3, the external diameter of connecting portion 3 bores the diameter of handle 2 more than ring-type, the external diameter of connecting portion 3 is less than the external diameter of circular hollow drill bit 1。
Further, for the convenient location observed and the heart is bored 4, the sidewall of circular hollow drill bit 1 is provided with multiple rectangle peephole。Multiple peepholes can uniform be arranged on the sidewall of circular hollow drill bit 1。Preferably, the sidewall of circular hollow drill bit 1 is laid with 3 rectangle peepholes。The length of peephole is the 0.5-0.8 of circular hollow drill bit 1 length, and the width of peephole is the 0.5-0.8 of circular hollow drill bit 1 diameter。The sight line that so can not either affect surgical staff ensure that again the intensity that circular hollow drill bit 1 is enough。
Distance between front end and place, the circular hollow drill bit 1 front end plane of some drill bit 41 is 1-5mm。When the heart namely bores 4 sites brill, the position of some drill bit 41 is positioned at the outside of place, circular hollow drill bit 1 front end plane, in use, first bores with point and positions, and emplacement depth is 1-5mm, and then circular hollow drill bit 1 just starts to bore。So it can be avoided that circular hollow drill bit 1 is in use subjected to displacement, it may appear that take ring-type bone inner and outer wall not with one heart, bone wall thickness is uneven and takes the phenomenons such as bone is imperfect。
Distance between front end and the circular hollow chisel edge place plane of fluted drill drill bit is 0-5mm。
Circular hollow drill bit 1 rear end is provided with annular joint face, and the internal diameter of annular joint face is more than the internal diameter of connecting portion 3, and the edge of annular joint face is connected with circular hollow drill bit 1 rear end, and the end, one end of connecting portion 3 is connected with annular joint face。
The other end of connecting portion 3 is provided with end face, and the end face that the end face of connecting portion 3 other end bores handle 2 with ring-type is connected。
Circular hollow drill bit 1, connecting portion 3 and ring-type are bored handle 2 and can be welded together after processing respectively, it is also possible to be integrated and process。
The work process of this example: by bore or fluted drill to the heart bore handle 42 be installed to connecting portion 3, ring-type is bored handle 2 and is installed on rotating driving device, point drill bit 41 or fluted drill drill bit 43 rotate with circular hollow drill bit 1 simultaneously, center is pinpointed, about 1mm under bone is pierced in circular hollow drill bit 1 front end, pull down and the heart is bored 4, after then continuing to be drilled into desired depth with circular hollow drill bit 1, then the endoporus boring bar tool of other implantation body's operation tools is got out internal ring required form。
Above one embodiment of the present of invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention。All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention。
