Abstract
The utility model provides a fixing device of a thighbone lesser trochanter. According to the technical scheme of the fixing device of the thighbone lesser trochanter, the fixing device comprises two linear handles which are connected through a hinge, arc-shaped covers are arranged on the two linear handles, all openings of one arc-shaped cover face to the other arc-shaped cover, through holes are arranged on the arc-shaped covers, a sleeve is installed on the through hole of one arc-shaped cover, and limit strips are arranged at one ends of the linear handles away from the arc-shaped covers. The fixing device can be used for fixing the thighbone lesser trochanter effectively, improve punching accuracy of an electric drill, and facilitate operation.
Description
Technical field
The utility model relates to a kind of clinical medicine Orthopeadic Surgery apparatus, especially a kind of lesser trochanter of femur holder.
Background technology
In the prior art, technique known is along with the progress of society and development, clinical medicine has also had the progress of advancing by leaps and bounds, orthopaedics particularly, wherein intertrochanteric fracture is intertrochanteric fracture of the femur again, mean the fracture at position between the large and small rotor of femur, all merge trochantinian fracture or extensive fracture.Fracture of the lesser trochanter or extensively fracture cause femur to resist external applied load and antitorque mechanical property significantly descends, its nearly folding section is subjected to the tractive of iliopsoas, the medium and small flesh of buttocks and other outward turning muscle groups and is flexing, abduction, outward turning deformity, therefore in the intertrochanteric fracture treatment, lesser trochanter fixedly is the factor that can not be ignored.But because lesser trochanter is positioned at the rear and important structure such as a burst arteriovenous, femoral nerve is arranged again on every side, to its anatomical reduction with fixedly be very difficult effectively, normally the doctor is rule of thumb now, pin with hands, punch with electric drill then, so very easily injure doctor's hands, and punching is not necessarily accurate, this is the existing in prior technology weak point.
Summary of the invention
The purpose of this utility model is exactly at the existing in prior technology deficiency, and provide a kind of technical scheme of lesser trochanter of femur holder, the holder of this scheme is the resected femur lesser trochanter effectively, and can improve the precision of electric drill punching, is conducive to the carrying out of performing the operation.
This programme is realized by following technical measures: a kind of lesser trochanter of femur holder, comprise two linear type handles that are connected through the hinge, be provided with the arc cover on described two linear type handles, the opening of described arc cover is all towards another arc cover, described arc cover is provided with through hole, at the through hole of an arc cover sleeve of hollow is installed, is provided with positive stop strip at described linear type handle away from an end of arc cover.Described positive stop strip is arc, and positive stop strip is provided with a plurality of limiting tooths.Described sleeve and through hole are fixed by screw thread.End away from the arc cover of described linear type handle is provided with rotating shaft, and the linear type handle can rotate along rotating shaft.The plane that described linear type handle rotates around the axis is vertical around the plane of hinge through with the linear type handle.Also be provided with on the described sleeve be used to the hole that screws that screws sleeve.Described linear type handle is provided with handle away from an end of arc cover.
The beneficial effect of this programme can learn according to the narration to such scheme, because the arc cover is arranged in this scheme, and can the resected femur lesser trochanter; At the arc cover through hole is arranged, be conducive to the electric drill punching like this, do not need the doctor to pin lesser trochanter of femur with hands, during punching, just can not injure doctor's hands; Be provided with sleeve in the through hole of an arc cover, during use, the arc cover that has sleeve is the entrance of electric drill, can guarantee the direction of electric drill punching like this, avoids beating tiltedly, brings wound to patient; Described sleeve and through hole are fixed by screw thread, are convenient to installing sleeve like this, when not using holder, sleeve can be unloaded, and are convenient to deposit; The linear type handle is provided with positive stop strip away from an end of arc cover, and after merging two linear type handle handles and clamping lesser trochanter of femur, positive stop strip will play fixation, has guaranteed the clamping degree of two linear type handle handles; End away from the arc cover of described linear type handle handle is provided with rotating shaft, linear type handle handle can rotate along rotating shaft, like this after clamping lesser trochanter of femur, linear type handle handle can be rotated, reduced the entire length of linear type handle handle like this, when having avoided operation, medical personnel have guaranteed normally carrying out of operation owing to handle is touched in carelessness; Screw the hole on the sleeve, when installing sleeve, can screw in the hole with a bar insertion, according to the hand of spiral rotational sleeve, just sleeve can be fixed on the arc cover.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is apparent.
