Abstract
The invention provides a pressurizing metal bone spicule, comprising a blade portion (1) on the front end, a tail portion (3) on the rear end, and a body (2) between the blade portion (1) and the tail portion (3). The metal bone spicule is characterized in that a first pressurization segment (21) and a second pressurization segment (22) are between the body (2) and the blade portion (1), and the first pressurization segment (21) is between the blade portion (1) and the second pressurization segment (22). The blade portion has effects of drilling, cutting, and chipping on bones, the first pressurization segment and the second pressurization segment generate pressure in a precession process through the bone spicule, and a problem of loosening after the bone spicule is implanted in a human body is preferably solved.
Description
Technical field
The present invention relates to a kind of spicule, belong to medical mechanical domain, more particularly it is a kind of trailed model metal bone needle.
Background technology
Existing bone surgery with the construction features of metal bone needle be: on metal bone needle, the front portion of the cylindrical body of rod connects the threaded portion with the conical periphery strengthened gradually from front to back, to screw in the bone of patient; The rearward end periphery of the body of rod has the Access Division of a plane formula, to use box spanner spire, carries out the screw-in of spicule or exits.A hang-up of puzzlement bone surgery is that seal wire must be brought into by spicule after implant into body, fixing, as binding, threading etc. for alternate manner.In addition, existing metal bone needle does not also have can to produce in precession process draw.
Summary of the invention
The object of the invention is to the weak point overcoming above-mentioned existing background technology, and a kind of trailed model metal bone needle is provided, it can produce draw by spicule in precession process, can solve spicule preferably after implant into body, guide seal wire to enter, and carries out the fixing of the mode such as bundle.
The object of the invention is to be reached by following measure: trailed model metal bone needle, it comprises the blade being positioned at front end, the afterbody being positioned at rear end, and the body between blade and afterbody, it is characterized in that there is thread segment between described body and blade, the diameter of described thread segment is greater than the diameter of body.
In technique scheme, described blade, thread segment, body and afterbody are integral type structure.
Tool of the present invention has the following advantages: blade has brill to bone, cut, the effect such as to cut, and thread segment produces draw by spicule in precession process, can solve spicule loosening and the problem of traction after implant into body preferably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Blade 1 in figure, thread segment 2, body 3, afterbody 4.
Detailed description of the invention
Describe performance of the present invention in detail below in conjunction with accompanying drawing, but they do not form limitation of the invention, only for example.Simultaneously by illustrating that advantage of the present invention will become clearly and easy understand.
Accompanying drawings is known: trailed model metal bone needle of the present invention, it comprises the blade 1 being positioned at front end, the afterbody 4 being positioned at rear end, and the body 3 between blade 1 and afterbody 4, it is characterized in that there is thread segment 2 between described body 3 and blade 1, the diameter of described thread segment 2 is greater than the diameter of body 3.Described blade 1, thread segment 2, body 3 and afterbody 4 is integral type structure.Afterbody pattern of the present invention can be designed to circle, square, can coordinate manually and power tool operation.
Other unspecified part all belongs to prior art.
Claims (2)
1. trailed model metal bone needle, it comprises the blade (1) being positioned at front end, the afterbody (4) being positioned at rear end, and the body (3) be positioned between blade (1) and afterbody (4), it is characterized in that there is thread segment (2) between described body (3) and blade (1), the diameter of described thread segment (2) is greater than the diameter of body (3).
2. trailed model metal bone needle according to claim 1, is characterized in that described blade (1), thread segment (2), body (3) and afterbody (4) are integral type structure.
