Abstract
The utility model discloses a hip joint function protector, which is used for the use of hip joint diseases. The utility model mainly comprises six main components of a transverse clamp of a thread nail, a height adjusting rod, a hinging joint, a main connecting body, a universal joint, a longitudinal clamp of a thread nail and a screw nail or screw bolt system fixed by the six main components. The utility model is respectively fixed on the upper part of a femoral bone and an acetabulum upper edge in a body by four thread nails outside the body and axle centers of a hinge and a hip joint in flexible movement are consistent. The utility model can obtain the purposes of supporting the hip joint and reducing the load in clinical use and can keep the flexible movement of the hip joint. The utility model can be used for the fusion fixation spanning the hip joint and can also be used for knee joint diseases.
Description
1. the present invention relates to a kind of external fixation medical apparatus and instruments of joint, i.e. the hip joint function protector.
2. the major function of hip joint is load-bearing and activity, and any coxarthropathy is decreased all influences its function of joint to some extent, even causes hip joint invalid.Coxarthropathy decreases that to cause bone as femur head necrosis, fracture of the femoral head and dislocation, acetabular bone fracture compound comminuted, neck of femur tumor damaged etc., need hip joint not bear a heavy burden after the operation and can carry out the early stage activity of bending and stretching: late period the hip joint infectious disease, should not fix at intralesional again after the operation.The traditional processing method in hip joint disease operation back is to carry out plaster fixation or traction, both be difficult to reach effective hip joint fixation, even can not resist the hip joint pressurized of all muscle contraction of hip or contracture generation, but also need long-term bed, finally cause arthrodesis syndromes such as ankylosis, amyotrophy, osteoporosis, be unfavorable for the recovery of disease.What at present the external fixed support for bone that uses only was used to fracture resets with fixing, when trans-articular uses then the joint lose active action (see " Chinese journal of orthopedics " 1996 the 4th phase 211 pages).The support hip joint be can reach and femoral head and acetabular bone heavy burden alleviated; can protect the hip joint activity to avoid joint accretion and stiff, osteoporosis, the local blood circulation of improvement etc. again; simultaneously can be used for hip joint again fixes; avoid IA operation to fix or large-scale plaster fixation; reach the early stage joint multifunctional protection device of ground activity purpose down; except that the designer had made relevant report (" Jiangxi medicine " 1997 the 3rd phase 141 pages), not seeing had report in addition.
3. the purpose of this hip joint function protector design is exactly to solve the problems referred to above that exist behind the hip joint disease operative treatment, reaches the functional exercise of bending and stretching that can carry out hip joint when supporting hip joint again, and also can be used for crossing over the joint and carries out the hip joint fusion.
4. the purpose of this utility model can take following measure to reach:
The hip joint function protector is that a kind of to be used for hip joint external by four drive screws 10,13 and hip week bone stationary device, and comprising: crosswise fixed nail folder 1, height regulating rod 2 connects main body 3, vertically staple folder 4, four major parts.Crosswise fixed nail folder is fixing by two screws 5 with height regulating rod, height regulating rod be connected main body and form Hinge joint 6 by an axle center, and the active bolt 11 of a may command Hinge joint arranged, connecting main body fixes by universal joint 7 and fixing lock 12 with vertical staple folder, crosswise fixed folder 1 is fixing by two screws 8 and two drive screws 10, and vertically fixation clamp 4 is fixing by two screws 9 and two drive screws 13.
5. the design of this multi-function protector has the movable and anchoring device of a height regulating rod and fixture and hinge; when placing the function and protecting device Hinge joint axle center in the hip joint outside consistent with femoral head center (hip joint bends and stretches movable axle center), both can reach and bend and stretch activity synchronously.Acetabular bone upper limb sclerotin is thicker, provides anatomic basis for putting drive screw support hip joint.The clinical treatment hip joint disease uses this function and protecting device, can reach the support hip joint, keeps hip joint to bend and stretch activity, can be used for crossing over the joint again and carries out the hip joint fusion, does not also increase operation wound, and the removal device nail pulling is convenient.
6. the drawing explanation of accompanying drawing
Accompanying drawing is the structure of this utility model hip joint function protector and uses sketch map.
The utility model is described in further detail below with reference to embodiment:
Medical stainless drive screw 10 levels that two screw threads are long 4 centimetres are inserted on the human body acetabular bone 0.5～1.0 centimetre; Fixing with drive screw 10 at external use alloy horizontal thread nail staple folder 1 by 2 pieces of soket head cap screws 8; The height regulating rod 2 of band garden cylindricality borrows a hinge axle center 6 to form Hinge joint with being connected main body 3, and Hinge joint lock 11 can be selected according to actual needs; Connecting main body 3 is connected by universal joint 7 with longitudinal screw nail fixation clamp 4,12 are the universal joint lock: height regulating rod 2 inserts horizontal thread nail folder central passage, regulate the height and the direction in hinge axle center 6, reach with hip joint and bend and stretch movable axle center when consistent, by two screws, 5 secured adjusted bar height; Adjust longitudinal screw nail fixation clamp direction, parallel with femur, fixedly the universal joint lock 12, insert the femur drive screw, and longitudinal screw is followed closely to be clipped in and externally fixed it by two screws 9.
Claims (3)
1, a kind of up and down each by 2 pieces of stock bone screw at the fixed hip joint function protector of external trans-articular; laterally nail folder, height regulating rod, connection main body, vertical nail folder four parts constitute; successively by height adjustment bolt lock, Hinge joint, three connections of universal joint; it is characterized in that: the acetabular bone bone two stock screws of hip joint one side are connected and fixed with horizontal nail folder; the femur two stock screws of opposite side are with after vertically the nail folder is connected and fixed, by universal joint be connected the main body connection.
2, hip joint function protector according to claim 1 is characterized in that: height regulating rod is cylindrical, and by horizontal nail folder central circular hole, crosswise fixed is folded with the fastening bolt of secured adjusted bar.
