Description

Acetabulum outer lower edge drag hook

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to an acetabulum outer lower edge drag hook.

Background

At present, the development of hip joint surgery is rapid, particularly total hip joint replacement, but the prior process of polishing the acetabulum in the hip joint replacement only depends on a draw hook to expose a surgery field and an assistant to fix the proximal end of the femur, the visual field is not well exposed in the process and the proximal end of the femur is easily damaged, and because the femur is directly exposed in the surgery field after reaming the marrow, the broken slag of polishing the acetabulum is easy to fall into the medullary cavity, thereby increasing the risk of the surgery, and further providing a device for assisting the acetabulum polishing in the total hip joint replacement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an outer lower edge drag hook of acetabular bone to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an outer lower edge drag hook of acetabular bone, includes the device body, the one end of device body is the handle, the one end that the device body kept away from the handle is equipped with fixed pointed end, be equipped with in the middle of the up end of device body and be used for blocking the recess that the piece that the acetabular bone was polished falls into femoral medullary cavity, be equipped with the fixed arch of thighbone in the middle of the lower terminal surface of device body.

As a further aspect of the present invention: the handle grip is downwardly curved.

As a further aspect of the present invention: the fixed tip is a triangle with an angle of 60 degrees.

As a further aspect of the present invention: the handle is provided with a through hole at one end far away from the fixed tip, so that the device body can be conveniently hung and placed.

As a further aspect of the present invention: the periphery that the up end of device body is located the recess is equipped with ring shape inclined plane, makes things convenient for the piece that the acetabulum was polished to fall into the recess and collects.

As a further aspect of the present invention: the edges and corners of the device body are chamfered, so that the phenomenon that human tissues are injured by collision in the operation is avoided.

Compared with the prior art, the utility model has the advantages of following several aspects:

the utility model discloses the during operation is fixed with fixed pointed end on the device body on the acetabular bone, and the fixed protruding of thighbone in the middle of the terminal surface blocks femoral medullary canal mouth under the device body, and downward fixation thighbone exposes the acetabular bone, increases the field of vision of operation, can also collect the piece that the acetabular bone was polished through the recess in the middle of the device body up end, prevents that the piece that the acetabular bone was polished from falling into femoral medullary canal, reduces the operation risk, has easy operation moreover, advantages such as economical and practical.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-4, an acetabulum outer and lower edge retractor comprises a device body 2, one end of the device body 2 is a handle 1, one end of the device body 2, which is far away from the handle 1, is provided with a fixed tip 4, a groove 3 for blocking fragments polished by acetabulum from falling into a femoral medullary cavity is arranged in the middle of the upper end surface of the device body 2, and a femoral fixing protrusion 6 is arranged in the middle of the lower end surface of the device body 2.

The handle 1 is bent downwards, the bending angle is 45 degrees, and a user can conveniently hold the handle 1 to perform operation.

The fixed tip 4 is a triangle with an angle of 60 degrees.

The handle 1 is provided with a through hole 5 at one end far away from the fixed tip 4, so that the device body 2 can be conveniently hung.

The periphery that the up end of device body 2 is located recess 3 is equipped with ring shape inclined plane, makes things convenient for the piece that the acetabulum was polished to fall into recess 3 and collects.

The edges and corners of the device body 2 are chamfered, so that the phenomenon that human tissues are injured by collision in the operation is avoided.

The utility model discloses a theory of operation is: the utility model discloses the during operation is fixed with fixed pointed end 4 on the device body 2 on the acetabulum, and the fixed protruding femur that blocks in the middle of the terminal surface under the device body 2 increases the field of vision of operation, and downward fixation thighbone exposes the acetabulum, can also collect the piece that the acetabulum was polished through recess 3 in the middle of the 2 up ends of device body, prevents that the piece that the acetabulum was polished from falling into the thighbone marrow cavity, reduces the operation risk, has easy operation moreover, advantages such as economical and practical.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
