Abstract
The special guider of a kind of pelvis, comprise a bow, hinged in the middle part of bow, bow both ends, be fixed with and be positioned at conplane sleeve, sleeve and bow two ends form an angle, bow hinge point both sides are connected with spring, and described sleeve is the arc to bow link projection, and barrel bore becomes little tubaeform of outer imperial palace.The special guider of this pelvis is in use convenient to fastening, prevent from, during inserting needle, displacement deflection occurs, adopt arc sleeve can inserting needle vertical with pelvis simultaneously, increase the firmness of Kirschner wire, sleeve adopts inner small and outside big is tubaeformly convenient to medical personnel's operation, increase success rate of operation, reduce patient painful.
Description
Technical field
This utility model relates to medical instruments field, particularly the special guider of a kind of pelvis.
Background technology
Pelvic structures is complicated, after the reduction of the fracture, many employing 2.5mm Kirschner Wire Drillings during row Interal fixation, because steel plate placement location is dark, abdominal viscera in pelvic cavity, important neural blood vessel gathers, and conventional sleeve mostly is straight sleeve, cannot be applied to fracture of pelvis boring, and Kirschner wire very easily damages abdominal viscera and important neural blood vessel in boring overshoot.
Utility model content
For solving above-mentioned prior art Problems existing; the purpose of this utility model is to provide a kind of pelvis special guider; the special guider of this pelvis is in use convenient to fastening, prevents from, during inserting needle, displacement deflection occurs, and adopts arc sleeve that pelvic cavity vital tissue not only can be protected to escape injury simultaneously; and can increase and appear; guarantee that boring direction is vertical with steel plate, increase fixing strength and stability, greatly can facilitate operation technique; save operating time, have a good application prospect.Sleeve adopts inner small and outside big is tubaeformly convenient to medical personnel's operation, increases success rate of operation, reduces patient painful.
For achieving the above object, the technical solution of the utility model is:
The special guider of a kind of pelvis, comprise a bow, hinged in the middle part of bow, bow both ends, be fixed with and be positioned at conplane sleeve, sleeve and bow two ends form an angle, bow hinge point both sides are connected with spring, and described sleeve is the arc to bow link projection, and barrel bore becomes little tubaeform of outer imperial palace.
Further, inside described sleeve and bow, angle is 100 °.
Further, hinge point both sides are provided with detent mechanism, detent mechanism comprises the connecting rod being arranged on bow hinge point both sides, the locating rod between two connecting rods being arranged on bow.
Further, described locating rod one end and rod hinge connection, the other end is fixed by bayonet socket.
Relative to prior art, the beneficial effects of the utility model are:
The special guider of this pelvis is in use convenient to fastening; prevent from, during inserting needle, displacement deflection occurs; adopt arc sleeve that pelvic cavity vital tissue not only can be protected to escape injury simultaneously; and can increase and appear; guarantee that boring direction is vertical with steel plate, increase fixing strength and stability, greatly can facilitate operation technique; save operating time, have a good application prospect.Sleeve adopts inner small and outside big is tubaeformly convenient to medical personnel's operation, increases success rate of operation, reduces patient painful.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-bow, 2-sleeve, 3-hinge point, 4-spring, 5-connecting rod, 6-locating rod, 7-is hinged, 8-bayonet socket.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are described in further detail:
As shown in Figure 1: the special guider of a kind of pelvis, comprise a bow 1, hinged in the middle part of bow 1, bow 1 both ends, be fixed with and be positioned at conplane sleeve 2, sleeve 2 and bow 1 two ends form an angle, bow 1 hinge point 3 both sides are connected with spring 4, and described sleeve 2 is the arc to bow 1 link projection, and sleeve 2 inner chamber becomes little tubaeform of outer imperial palace.
Further, inside described sleeve 2 and bow 1, angle is 100 °.
Further, hinge point 3 both sides are provided with detent mechanism, detent mechanism comprises the connecting rod 5 being arranged on bow 1 hinge point 3 both sides, the locating rod 6 between two connecting rods 5 being arranged on bow 1.
Further, described locating rod 6 one end and connecting rod 5 hinged 7, the other end is fixed by bayonet socket 8.
Operation principle of the present utility model is:
In actual use, locating rod 6 is put down by bayonet socket 8, bow 1 is bent laterally along hinge point 3, spring 4 is strained, after determining position, bow 1 is resetted, locating rod 6 is clamped by bayonet socket 8, at this moment, sleeve 2 keeps vertical with pelvis inserting needle skeleton, being convenient to inserting needle is convenient to fastening, prevent from, during inserting needle, displacement deflection occurs, adopt arc sleeve that pelvic cavity vital tissue not only can be protected to escape injury simultaneously, and can increase and appear, guarantee that boring direction is vertical with steel plate, increase fixing strength and stability, greatly can facilitate operation technique, save operating time, have a good application prospect.Sleeve adopts inner small and outside big is tubaeformly convenient to medical personnel's operation, increases success rate of operation, reduces patient painful.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
