Abstract
The utility model discloses a guiding device for orthopaedics drill hole, and comprises a guiding body, a needle insertion seat arranged on one end of the guiding body and a guiding positioning device which is arranged on the other end of the guiding body and is parallel to the needle insertion seat, wherein the guiding positioning device comprises a plurality of positioning needle guiding holes arranged on the end portion of the guiding body, a needle guiding device is arranged in the positioning needle guiding hole, a positioning hole is arranged on the needle guiding device, a screw hole which is communicated with and is perpendicular to the positioning needle guiding hole is arranged on the guiding body, a fastening screw is arranged in the screw hole, a plurality Kirschner pin holes for allowing to pass through Kirschner pins are arranged on the needle insertion seat, and the Kirschner pins correspond to the positioning hole. The guiding device has simple structure, convenient operation and accurate positioning and guiding.
Description
Technical field
This utility model relates to medical apparatus and instruments ancillary technique field, relates in particular to the boring guider that uses in a kind of bone surgery process.
Background technology
Clinically at present, internal fixation for nearly joint part fracture adopts screw more or has just followed closely fixing, and often use Kirschner wire in the operation as guide needle, traditional boring method mostly adopts the range estimation aiming, direction and length all are difficult to grasp, and the accuracy that is difficult to guarantee inserting needle and goes out pin, cause easily repeatedly repeat squeeze into, cause the damage of joint surrounding tissue, existing boring guider generally all needs some holes for the insertion of different-diameter Kirschner wire, but it is suitable to need some inserting needle bases like this, operation inconvenience, and the bar point of existing vertical orientation bar is not easy with the needle point of Kirschner wire perpendicularly, and horizontal orientation bar and vertical orientation bar are fixed with trip bolt, because of there being certain clearance between the three, if deviation or fastening loosening is arranged, make bar point and inserting needle base not in same horizontal vertical position easily, lose the meaning of guiding, and the positioning and guiding bar can not free adjustment, has certain limitation.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, easy to operate, the boring guider of the accurate and adjustable orthopaedics of positioning and guiding.
For solving the problems of the technologies described above, the technical solution of the utility model is: the boring guider of orthopaedics, comprise the guiding body, be arranged on the inserting needle seat of described guiding body one end and be arranged on the parallel with described inserting needle seat guide locating device provided of the described guiding body other end, the described guide locating device provided some location guide pinhole that is arranged on described guiding body end that comprises, be provided with the guide pin device in the guide pinhole of described location, described guide pin device is provided with locating hole, what described guiding body was provided with is connected and vertical screw with described location guide pinhole, is provided with trip bolt in the described screw; Described inserting needle seat is provided with can be by some Kirschner wires hole of Kirschner wire, and described Kirschner wire hole is corresponding with described locating hole.
Owing to adopted technique scheme, reduce handle by directly holding the guiding body, reduce cost, and it is corresponding with locating hole by the Kirschner wire hole, make accurate positioning, make inserting needle seat and Kirschner wire remain at same horizontal vertical position, make guiding accurately, conveniently by the guide pin device, relatively simple for structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing is the structure cutaway view of this utility model embodiment.
The specific embodiment
As shown in the figure, the boring guider of orthopaedics, comprise guiding body 1, what be arranged on the inserting needle seat 2 of described guiding body 1 one ends and be arranged on described guiding body 1 other end is parallel with described inserting needle seat 2 guide locating device provided, the described guide locating device provided some location guide pinhole 3 that is arranged on described guiding body 1 end that comprises, be provided with guide pin device 8 in the described location guide pinhole 3, described guide pin device 8 is provided with locating hole 9, described guiding body 1 location that be provided with and described guide pinhole 3 is connected and vertical screw 4, is provided with trip bolt 5 in the described screw 4; Described inserting needle seat 2 be provided with can be by Kirschner wire 7 some Kirschner wires hole 6, described Kirschner wire hole 6 is corresponding with described locating hole 9.
Described guide pin device 8 is the guide board that described Kirschner wire 7 of scalable and described guide pin device 8 surround cavity size, can guarantee the fixing of the required boring of patient position by regulating cavity.
Described inserting needle seat 2 is provided with the different Kirschner wire hole 6 of some diameter, to adapt to the inserting needle demand of different patient's different parts.
Before the boring, select suitable Kirschner wire 7 and pass Kirschner wire hole 6 according to clinical needs, select location guide pinhole 3 according to suffering from the limb thickness, then guide pin device 8 is inserted, make Kirschner wire 7 pass locating hole 9 in the lump, with screw 5 that guide pin device 8 is fixing then, during boring, doctor's one hand-held guider, put into the cavity that location guide pin device 8 and inserting needle seat 2 surround suffering from limb, make locating hole 9 and Kirschner wire 7 on the guide pin device 8 to go out pin mark consistent, another hand-held electric drill that has Kirschner wire 7 pierces Kirschner wire 7 and to suffer from limb and can finish directional drilling from the Kirschner wire hole 6 on the inserting needle seat 2.By regulating the size that the required cavity of trouble limb can be regulated in guide pin device 8 and corresponding Kirschner wire hole 6, simple and convenient.
