Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically, relate to a trinity drag hook of thighbone for hip joint replacement.
Background
Artificial hip arthroplasty is a procedure in which the articular surface damaged by disease or injury is replaced with a femoral head prosthesis and an acetabular prosthesis. The joint of the hip joint and the femoral head is an acetabulum, and the joint capsule at the acetabulum is required to be removed before replacement. At present, basic surgical instruments in the artificial hip joint replacement are traumatic orthopedic instruments, and the lack of special hip joint replacement instruments is the main reason for difficult exposure and relatively long operation time of artificial hip joint replacement. Currently, when a femur is treated in the artificial total hip arthroplasty, 2-3 acetabulum draw hooks are generally used, wherein one acetabulum draw hook is used for prying up the proximal end of the femur (the osteotomy stump of the femoral neck) to enable the proximal end of the femur to be separated from the acetabulum (namely the deep tissue), and the other acetabulum draw hook is used for retracting the lateral tissues of the lesser tuberosity (including local fascia, muscles and the like). Sometimes, the acetabulum retractor is needed to pull back the gluteus medius, so that the proximal end of the femur after osteotomy can be fully exposed. Thus, three draw hooks and three hands are needed for exposing the proximal end of the femur, and more manpower is consumed.
Disclosure of Invention
An object of the utility model is to provide a trinity drag hook of thighbone for hip joint replacement to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
The utility model provides a trinity drag hook of thighbone for hip joint replacement, includes handle, drag hook body, drag hook, the drag hook body is located the handle front end, the drag hook is including locating the main hook of drag hook body front end, locate the vice hook in the outside in the drag hook body outside, locate the inboard vice hook of drag hook body, inboard vice hook, the relative setting of the vice hook in the outside are from this internal, outside both sides of drag hook respectively to the hook body upside upward hook. Here, the main hook may pry up the proximal femur (femoral neck osteotomy stump), the medial sub-hook may block the medial (small tuberosity side) soft tissue (gluteus maximus and its fascia), and the lateral sub-hook may block the lateral (large tuberosity side) soft tissue (gluteus maximus, gluteus medius, and fascia).
preferably, the front end of the handle, the drag hook body and the main hook form an inverse arch structure facing the lower side of the drag hook body, so that the main hook can pry up the proximal end of the femur (the femoral neck osteotomy stump).
Preferably, the front end of the main hook is in a rounded trapezoid shape, so that unnecessary muscle and bone injury caused by too sharp edges of the main hook is prevented, and the main hook is not easy to slip in traction and improves the using effect.
Preferably, the tail end of the handle is provided with a through hole. Through the through hole, a heavy object can be hung in the operation process, so that not only can manpower be saved and fatigue be prevented, but also the input of personnel in the operation is reduced and the human error is prevented; in addition, the through hole is convenient for hanging and keeping when the draw hook is not used, and the body of the draw hook is prevented from contacting with an infection source. Here, the shape of the through hole is generally circular, and may be other shapes such as square, triangle, and the like.
compared with the prior art, the beneficial effects of the utility model are that: three-in-one draw hook of thighbone for hip joint replacement, through the innovative structural design, make one draw hook have the function of three draw hooks in the past concurrently, realize that the elastic part of inside and outside soft tissue offsets each other, and the draw hook can not the roll-off, accomplish fully exposing the thighbone near-end, reach the effect that only needs one hand to grasp the handle of three-in-one draw hook in the art can, have the time of using manpower sparingly, need not to insert the draw hook repeatedly, improve the characteristics of operation efficiency.
Drawings
FIG. 1 is a side view block diagram of an embodiment of the present invention;
FIG. 2 is a front view of the embodiment of the present invention;
Wherein: 1. the handle, 2 the drag hook body, 3 the main hook, 4 the outside auxiliary hook, 5 the inside auxiliary hook, 6 the circular through hole.
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.
Referring to fig. 1, fig. 2, a trinity drag hook of thighbone for hip joint replacement, including handle 1, drag hook body 2, drag hook body 2 locates 1 front end of handle, the drag hook is including locating the main hook 3 of 2 front ends of drag hook body, locate the vice hook 4 in the outside in the drag hook body 2 outside, locate the inboard vice hook 5 of drag hook body 2 inboard, inboard vice hook 5, the relative setting of the vice hook 4 in the outside follow drag hook body 2 respectively inside and outside both sides to the hook body 2 upside upper hook. Here, the main hook 3 may pry up the proximal femur (femoral neck osteotomy stump), the inner auxiliary hook 5 may block the inner (small tuberosity side) soft tissue (gluteus maximus and fascia thereof), and the outer auxiliary hook 4 may block the outer (large tuberosity side) soft tissue (gluteus maximus, gluteus medius and fascia).
the front end of the handle 1 and the drag hook body 2 and the main hook 3 form an inverse arch structure facing the lower side of the drag hook body 2, so that the main hook 3 can pry up the proximal femur (the femoral neck osteotomy stump).
The front end of the main hook 3 is in a rounded trapezoid shape, on one hand, unnecessary muscle and bone injury caused by too sharp edges of the main hook 3 is prevented, on the other hand, slipping is not easy to occur in traction, and the using effect is improved.
The tail end of the handle 1 is provided with a through hole. Through the through hole, a heavy object can be hung in the operation process, so that not only can manpower be saved and fatigue be prevented, but also the input of personnel in the operation is reduced and the human error is prevented; in addition, the through hole is convenient for hanging and keeping when the draw hook is not used, and the draw hook body 2 is prevented from contacting with an infection source. Here, the through-hole is a circular through-hole 6.
Like this, the drag hook of this embodiment has just had the function that three drag hooks just can realize in the past concurrently, and through the inboard auxiliary hook 5, the auxiliary hook 4 in outside that set up relatively, can make the elastic part of inside and outside soft tissue offset each other, and the drag hook can not the roll-off to accomplish the abundant exposure to the thighbone near-end, reach only need one hand in the art to grasp the effect that handle 1 of trinity drag hook can.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
