Abstract
The utility model provides a technical scheme of a femur lesser trochanter fixing device used in the clinical orthopedic surgery. The femur lesser trochanter fixing device adopting the technical scheme comprises a first handle and a second handle which are connected through a hinge, wherein the part of the first handle, which is on one side of the hinge, is arc-shaped, and the other part of the first handle, which is on the other side of the hinge, is linear; the second handle is linear; two arc-shaped hoods are respectively arranged at the arc-shaped end parts of the first handle and another arc-shaped hood is arranged at one end of the second handle, and the three arc-shaped hoods are arranged on the same side, and the openings of the two arc-shaped hoods face another arc-shaped hood; a through hole is formed in each arc-shaped hood; a sleeve is arranged in the through hole of the arc-shaped hood of the second handle; and limit bars are arranged at the ends of the handles, which are far from the arc-shaped hoods. The femur lesser trochanter fixing device adopting the technical scheme can efficiently fix a femur lesser trochanter, improves the drilling precision of an electric drill, and is beneficial for an operation.
Description
Technical field
The utility model relates to a kind of clinical medicine Orthopeadic Surgery apparatus, especially a kind of clinical Orthopeadic Surgery lesser trochanter of femur fixture.
Background technology
Intertrochanteric fracture is intertrochanteric fracture of the femur again, means the fracture at position between the large and small rotor of femur, merges trochantinian fracture or extensive fracture more.Fracture of the lesser trochanter or extensively fracture cause femur to resist external applied load and antitorque mechanical property significantly descends, the nearly section of its fracture is flexing, abduction, outward turning deformity because the tractive that is subjected to iliopsoas, the medium and small flesh of buttocks and other outward turning muscle groups makes limbs, 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, fix with hands, punch with electric drill then, the weak point of this method be keep reset insecure, the punching direction is inaccurate, and very easily injures doctor's hands.
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 clinical Orthopeadic Surgery lesser trochanter of femur fixture, comprise two handles that are connected through the hinge, first handle is camber in a side of hinge, another is surveyed and is linear type, second handle is the linear type handle, the end of the arc of described first handle is provided with the arc cover, one end of second handle is provided with the arc cover, the arc cover of second handle and the arc cover of first handle are arranged on the same side, the opening of described two arc covers is all towards another arc cover, described arc cover is provided with through hole, at the through hole of second handle arc cover the sleeve of hollow is installed, described first handle and second handle are provided with positive stop strip 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.End away from the arc cover of described first handle and second handle is provided with rotating shaft, and described first handle and second handle all can rotate along rotating shaft separately.The plane that described first handle rotates around the axis is vertical around the plane of hinge through with two handles, and the plane that second handle rotates around the axis is vertical around the plane of hinge through with two handles.Described first handle and second handle are provided with handle away from the end of arc cover one end.
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; One side of first handle is arc, in the time of clamping lesser trochanter of femur, does not need the muscle of whole thigh is opened, and an end of arc is inserted thigh turn to the lesser trochanter of femur place then, merges two handles clampings and gets final product; In the through hole of second handle arc cover, be provided with sleeve, can play the guiding role, train off when avoiding the electric drill punching, avoid causing wound to patient; Described first handle and second handle are provided with positive stop strip away from an end of arc cover, and when clamping lesser trochanter of femur, positive stop strip can effectively be fixed two handles, prevent that handle is loosening; End away from the arc cover of first handle and second handle is provided with rotating shaft, and handle just can rotate around the axis like this, after clamping lesser trochanter of femur, two handles are rotated around the axis, so just can reduce the entire length of handle, avoid in the operation process, handle is run into by medical personnel.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.
