Abstract
The invention provides a thighbone lesser trochanter fixator which comprises two linear type handles which are connected through a hinge, wherein the two linear handles are respectively provided with an arc-shaped cover, an opening of one arc-shaped cover faces the other arc-shaped cover, a through hole is formed in each arc-shaped cover, a sleeve is installed on the through hole of one arc-shaped cover, and one end of each linear handle, away from each arc-shaped cover, is provided with a limiting strip. The fixator can effectively fix the thighbone lesser trochanter, meanwhile can improve precision of punching of an electrical drill, and is beneficial for proceeding of an operation.
Description
Technical field
What the present invention relates to is a kind of clinical medicine Orthopeadic Surgery apparatus, especially a kind of thighbone lesser trochanter fixator.
Background technology
In the prior art, known technology is progress along with society and development, clinical medicine there has also been the progress of advancing by leaps and bounds, particularly orthopaedics, 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 extensively fracture.Fracture of the lesser trochanter or extensively fracture cause femur to resist external applied load and antitorque mechanical property significantly declines, its nearly trisection is flexing, abduction, outward turning deformity by the tractive of iliopsoas, the medium and small flesh of buttocks and other outward turning muscle groups, therefore, in treatment of intertrochanteric fracture of femur, lesser trochanter is fixedly the factor that can not be ignored.But be positioned at rear due to lesser trochanter and have again burst important feature such as arteriovenous, femoral nerve around, to its anatomical reduction be effectively fixedly very difficult, present normally doctor rule of thumb, pin with hands, then punch with electric drill, so very easily injure the hands of doctor, and punching is not necessarily accurate, this is the weak point existing for prior art.
Summary of the invention
Object of the present invention is exactly for the deficiency existing for prior art, and a kind of technical scheme of thighbone lesser trochanter fixator is provided, the holder of the program can effective resected femur lesser trochanter, and can improve the precision of electric drill punching, is conducive to the carrying out of performing the operation.
This programme is achieved by the following technical measures: a kind of thighbone lesser trochanter fixator, comprise two the linear type handles be connected through the hinge, described two linear type handles are provided with arc-shaped cover, the opening of described arc-shaped cover is all towards another arc-shaped cover, described arc-shaped cover is provided with through hole, the through hole of an arc-shaped cover is provided with the sleeve of hollow, at described linear type handle, one end of arc-shaped cover is provided with positive stop strip.Described positive stop strip is arc, and positive stop strip is provided with multiple limiting tooth.Described sleeve and through hole are fixed by screw thread.One end away from arc-shaped cover of described linear type handle is provided with rotating shaft, and linear type handle can along axis of rotation.The plane that described linear type handle rotates around the axis and the plane orthogonal that linear type handle rotates around hinge.Described sleeve is also provided with and screws hole for what screw sleeve.Described linear type handle is provided with handle away from one end of arc-shaped cover.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to having arc-shaped cover in this scenario, and can resected femur lesser trochanter; Arc-shaped cover there is through hole, is conducive to electric drill punching like this, does not need doctor to pin lesser trochanter of femur with hands, during punching, the hands of doctor would not be injured; In the through hole of an arc-shaped cover, be provided with sleeve, during use, be the entrance of electric drill with sleeved arc-shaped cover, the direction that electric drill punches can be ensured like this, avoid beating tiltedly, bring 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, being convenient to deposit; Linear type handle is provided with positive stop strip away from one end of arc-shaped cover, and after merging two linear type handle clamping lesser trochanter of femur, positive stop strip will play fixation, ensure that the clamping degree of two linear type handle; One end away from arc-shaped cover of described linear type handle is provided with rotating shaft, linear type handle can along axis of rotation, like this when after clamping lesser trochanter of femur, linear type handle can be rotated, which reduce the entire length of linear type handle, when avoiding operation, medical personnel touch handle due to carelessness, ensure that normally carrying out of operation; Sleeve screws hole, when installing sleeve, can insert with a bar and screw in hole, according to hand of spiral rotational sleeve, just sleeve can be fixed on arc-shaped cover.As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.

Fig. 2 is the structural representation without holder during sleeve.
Fig. 3 is the right view of Fig. 2.
In figure, 1 is linear type handle, and 2 is hinge, and 3 is arc-shaped cover, and 4 is sleeve, and 5 is positive stop strip, and 6 is limiting tooth, and 7 is rotating shaft, and 8 is handle, and 9 for screwing hole, and 10 is through hole.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, the thighbone lesser trochanter fixator of this programme, comprise two the linear type handles 1 connected by hinge 2, described two linear type handles 1 are provided with arc-shaped cover 3, the opening of described arc-shaped cover 3 is all towards another arc-shaped cover, described arc-shaped cover 3 is provided with through hole 10, the through hole of an arc-shaped cover 3 is provided with the sleeve 4 of hollow, at described linear type handle 1, one end of arc-shaped cover 3 is provided with positive stop strip 5.Described positive stop strip 5 is arc, and positive stop strip 5 is provided with multiple limiting tooth 6.Described sleeve 4 is fixed by screw thread with through hole.One end away from arc-shaped cover 3 of described linear type handle 1 is provided with rotating shaft 7, and linear type handle 1 can rotate along rotating shaft 7.The plane orthogonal that the planes of described linear type handle 17 rotations around the shaft and linear type handle 1 rotate around hinge 2.Described sleeve 4 is also provided with and screws hole 9 for what screw sleeve 4.Described linear type handle 1 is provided with handle 8 away from one end of arc-shaped cover 3.
The present invention is not limited in above-mentioned detailed description of the invention, the change that those of ordinary skill in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
