Description
Technical field
The utility model relates to the field of medical instrument technology, in particular, being related to a kind of infant hip joint operation retractor.
Background technique
Developmental hip joint depauperation (DDH) is also known as developmental dislocation of hip joint, is that the common hip of children's orthopaedics mouth closes
Disease is saved, for disease incidence 1% or so, the disease incidence of girl is 6 times of boy, and left side is about 2 times of right side, and bilateral accounts for about
35%.DDH includes the dislocation of hip joint, subluxation and acetabular dysplasia.Purpose to DDH treatment is the concentric of acquisition hip joint
Circle resets, the condition that could only in this way provide for femoral head and acetabular development, while to prevent femoral head ischemic necrosis.More
Early treatment, effect are better.
In existing DDH treatment operation, to use and femoral head is pulled to drag hook, femoral head is pulled out from acetabular bone
It is cleaned, but current hook for surgery operation, when in use and inconvenient, the contact surface of drag hook and femoral head is small, is pressurized
Greatly, femoral head is caused to be easy to be damaged.The coupler body of its drag hook for pulling femoral head is not adapted to femoral head.Therefore, having must
Design a kind of infant hip joint operation special drag hook.
Utility model content
A kind of infant hip joint operation provided the purpose of the utility model is to overcome the deficiency of the above-mentioned prior art
Use drag hook.
The utility model solves technical solution used by prior art problem: including coupler body, connecting rod and knob；
The coupler body is hemispherical shell structure, and the connecting rod front end is fixedly connected with the coupler body side edge；It is described
Connection rod rear end is rotatedly connected with the knob front end by a fastening bolt；The outer surface of the knob is equipped with one and the drawing
The vertical round finger ring of palmistry, the finger ring hole direction of the circle finger ring and the knob front-rear direction are perpendicular.
Above technical scheme is further elaborated below:
Preferably, the outer surface of the knob offers a through-hole for running through its inner surface.
Preferably, the knob outer surface is additionally provided with a plurality of antiskid groove.
Preferably, the connecting rod and the knob are flat structure.
Preferably, the coupler body, connecting rod and the knob are stainless steel material.
The utility model has the beneficial effects that
One, a kind of infant hip joint operation retractor provided by the utility model are carrying out art to patient's hip joint
When preceding cleaning, the femoral head of hip joint is caught on by the coupler body of half shell structure, and femoral head is pulled open from acetabular bone.It is right again
Acetabular bone position is cleared up；The coupler body and femoral head contact area of half shell structure are big, it is small to be pressurized, are hardly damaged femoral head table
Face；The connecting rod is rotatably connected with the knob, by adjusting the angle of knob with connecting rod, avoids when drawing
Hamper cleaning work.
Secondly, a kind of infant hip joint operation retractor provided by the utility model, drawing when, can also will
Index finger protrudes into the round finger ring, and drawing can be made more stable.
Thirdly, in the utility model embodiment, infant hip joint operation retractor, when drawing, the knob table
The antiskid groove in face can increase the frictional force of knob and palm, so that medical staff is not likely to produce skidding when drawing,
Further increase the stability of drawing.

Specific embodiment
The technical solution of the utility model is described in detail below with reference to drawings and the specific embodiments, to become apparent from, directly
See the invention essence that ground understands the utility model.
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3；
In one embodiment, a kind of infant hip joint operation retractor provided by the utility model, including coupler body
10, connecting rod 20 and knob 30；
The coupler body 10 is that hemispherical shell structure, 20 front end of connecting rod and 10 side of coupler body connect along fixed
It connects；20 rear end of connecting rod is rotatedly connected with 30 front ends of the knob by a fastening bolt 201；The appearance of the knob 30
Face is equipped with one and 30 perpendicular round finger rings 301 of the knob, the finger ring hole direction of the round finger ring 301 with it is described
30 front-rear directions of shaking hands are perpendicular.
It is understood that passing through the coupler body 10 of half shell structure when carrying out preoperative cleaning to patient's hip joint
The femoral head for catching on hip joint pulls open femoral head from acetabular bone.Acetabular bone position is cleared up again；The coupler body of half shell structure
10 with femoral head contact area it is big, be pressurized it is small, be hardly damaged femoral head surfaces；The connecting rod 20 can be rotated with the knob 30
Connection avoids hampering cleaning work when drawing by adjusting the angle of knob 30 with connecting rod 20.Drawing when
It waits, index finger can also be protruded into the round finger ring 301, drawing can be made more stable.
In another embodiment, a kind of infant hip joint operation retractor provided by the utility model, the knob 30
