Description
Technical Field
The utility model relates to an orthopedic surgery apparatus field especially relates to an acetabular bone drag hook.
Background
The hip joint replacement is an effective means for treating the final stage disease of the hip joint, however, the acetabulum is deep, the exposure in the replacement is relatively difficult, particularly, the posterior lower part of the acetabulum is exposed by commonly used S draw hooks or common acetabulum draw hooks, but the S draw hooks are easy to displace and labor-consuming, and the front ends of the common acetabulum draw hooks are too sharp, so that bony tissues are easy to damage and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the main technical problem that the not enough to prior art provides an acetabular bone drag hook, and this drag hook is indestructible osseous tissue and soft tissue, and has stronger gripping power, and the drag hook of a body structure makes overall stability high, atress non-deformable.
In order to solve the technical problem, the utility model discloses a following technical scheme:
an acetabulum drag hook comprises a handle portion, a connecting portion and a drag hook portion, wherein the connecting portion has a certain radian, and the drag hook portion is sheet-shaped.
According to the scheme, the two sides of the hook portion are bent towards the bone tissue contact portion behind and below the acetabulum. So that the contact part of the hook part and the bone tissue has stronger gripping force, and the bone tissue and the soft tissue can not be easily injured, thereby avoiding the secondary injury of the patient.
In the scheme, the radian of the connecting part is 100-140 degrees.
Further, the radian of the connecting part is 120 degrees.
Above-mentioned scheme is further, the tail end of handle portion is provided with first through-hole. The handle part is grasped by hands, and the forefinger is put into the first through hole, so that force application is facilitated.
Above-mentioned scheme is further, handle portion is connected with application of force portion, be provided with the second through-hole on the application of force portion. Of course, the index finger can be put into the second through hole and directly pulled by force.
In addition, the handle part, the connecting part, the pulling hook part and the force application part are integrally formed. The drag hook of an integrated structure has high overall stability and is not easy to deform under stress.
Compared with the prior art, the utility model discloses an acetabular bone drag hook beneficial effect:
1. the hook pulling part is sheet-shaped, and two sides of the hook pulling part are bent towards the bone contact part behind and below the acetabulum, so that bony tissues and soft tissues are not easily injured, and the patient is prevented from being injured again;
2. the radian of the connecting part is favorable for extending the hook part into the rear lower part of the acetabulum to expose an incision area, so that the operation of a main surgeon cannot be blocked;
3. handle portion tail end is provided with first through-hole and application of force portion is provided with the second through-hole for there are two kinds of application of force modes, and handle portion is held in the first kind of hand, and the forefinger is put into first through-hole, carries out the application of force. The second method is that the forefinger is directly put into the second through hole to apply force;
4. the drag hook overall stability of a body structure is high, atress non-deformable, and when the finger stretched into the interior application of force of first through-hole or second through-hole in addition, the transmissibility was better, guaranteed that the drag hook can have the firm acetabulum rear lower place of firmly holding of sufficient power, showed the operation position completely.
Drawings
Fig. 1 is a schematic view of an acetabular bone retractor.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the acetabular bone retractor comprises a handle portion 1, a first through hole 12 is formed in the tail end of the handle portion 1, a doctor holds the handle portion with his hand, puts an index finger into the first through hole, and applies force to expose an operation portion. Of course, to prevent slipping, a screw thread or slip-resistant sleeve may be provided on the handle portion. In order to make the doctor more be favorable to the application of force, it is preferred, handle portion 1 is connected with application of force portion 4, be provided with second through-hole 41 on the application of force portion 4, put into the second through-hole with the forefinger, directly exert oneself, of course, can be provided with two through-holes on the application of force portion, the doctor can put into two fingers and drag and draw, and is convenient laborsaving more.
The handle portion 1 is connected with the connecting portion 2, the radian of the connecting portion 2 is 120 degrees, of course, other radians can also be used in the utility model, for example, the radian is 100 degrees ~ 140 degrees all can. The connecting part can be beneficial to extending the hook part into the rear lower part of the acetabulum and is beneficial to force application.
The connecting part 2 is connected with a hook part 3, the hook part 3 is sheet-shaped, and two sides of the hook part are bent towards the bone tissue contact part at the back lower part of the acetabulum. Mainly be difficult for injury osseous tissue and soft tissue, secondly, can draw hook portion flexion can with the soft tissue laminating, can expose the incision region easily, can not block the operation of main sword doctor.
Handle portion 1, connecting portion 2, draw hook portion 3 and application of force portion 4 are integrated into one piece, and the drag hook overall stability of a body structure is high, atress non-deformable, and when the finger stretched into the interior application of force of first through-hole or second through-hole in addition, the transmissibility was better, and it can have the below of sufficient power promptly acetabulum rear to guarantee the drag hook, shows the operation position completely. The whole draw hook is made of medical high-strength stainless steel, and the draw hook is not easy to deform even under larger force in the using process.
Compared with the prior art, the utility model discloses an acetabular bone drag hook beneficial effect:
1. the hook pulling part is sheet-shaped, and two sides of the hook pulling part are bent towards the direction of a bone tissue contact part behind and below the acetabulum, so that bony tissues and soft tissues are not easily injured, and the patient is prevented from being injured again;
2. the radian of the connecting part is favorable for extending the hook part into the rear lower part of the acetabulum to expose an incision area, so that the operation of a main surgeon cannot be blocked;
3. handle portion tail end is provided with first through-hole and application of force portion is provided with the second through-hole for there are two kinds of application of force modes, and handle portion is held in the first kind of hand, and the forefinger is put into first through-hole, carries out the application of force. The second method is that the forefinger is directly put into the second through hole to apply force;
4. the drag hook overall stability of a body structure is high, atress non-deformable, and when the finger stretched into the interior application of force of first through-hole or second through-hole in addition, the transmissibility was better, guaranteed that the drag hook can have the firm acetabulum rear lower place of firmly holding of sufficient power, showed the operation position completely.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
