Embodiment 1

[0035] see Figure 1-8 According to an embodiment of the present invention, a bone plate fixation device conforming to the bone healing process includes a bone plate 1, a femur 2 and a supporter 10, the bone plate 1 includes an upper bone plate 3 and a lower bone plate 4, the The upper part 3 of the bone plate is arranged on the upper end of the lower part 4 of the bone plate inclined outward, the upper part 3 of the bone plate and the lower part 4 of the bone plate are detachably connected, and the femur 2 includes a femoral shaft 5 and a femoral head 6 , the femoral neck 7 and the greater trochanter 8, the lower part of the bone plate 4 is inserted with a fixing screw 9, the fixing screw 9 is inserted into the femoral shaft 5, and the upper part of the bone plate 3 is provided with the The fitting plate 39 on the outer surface of the femur 2, the fitting plate 39 is inserted with a secondary fixing screw 40, the secondary fixing screw 40 is inserted into the greater trochanter...

Embodiment 2

[0037] see figure 1 and Figure 8 , for the upper part 3 of the bone plate, the bottom end of the upper part 3 of the bone plate is fixed with an inserting plate 35, and the top end of the lower part 4 of the bone set is provided with a slot 36 matching the inserting plate 35, the bone set Screws 37 are fixedly inserted on the outer wall of the lower part 4 of the board, and the ends of the screws 37 are inserted into the inserting board 35 .

[0038] Through the above scheme of the present invention, the beneficial effect is that the bottom end of the upper part 3 of the bone plate is fixed with a plugging plate 35, the top of the lower part 4 of the bone plate is provided with a slot 36 matching the plugging plate 35, and the plugging plate 35 is inserted into the slot 36 , fixed by screws 37, so the upper part 3 of the bone plate and the lower part 4 of the bone plate can be disassembled, and when a single part is damaged, it is convenient for a single replacement, avoidin...

Embodiment 3

[0040] see image 3 For the lower part 4 of the bone plate, several locking screw holes 38 matching the fixing screws 9 are provided on the lower part 4 of the bone plate, and a plurality of locking screw holes 38 matching the fixing screws 9 are provided on the fitting plate 39 . Matching secondary slot.

[0041] Through the above scheme of the present invention, the beneficial effect is that the locking screw hole 38 on the bone plate 1 is threaded and locked with the fixing screw 9, and the angle stability is good after locking. It can also be set in this way to adjust the relationship between the bone plate 1 and the femur 2 The distance between bone plates 1 does not directly contact the femur 2, reducing the impact of bone plate 1 on the periosteum blood supply. It should be noted that there are threads in the auxiliary socket.

Abstract

The bone fracture plate fixing device comprises a bone fracture plate, a thighbone and a supporting device, the bone fracture plate comprises a bone fracture plate upper portion and a bone fracture plate lower portion, the bone fracture plate upper portion is obliquely arranged at the upper end of the bone fracture plate lower portion outwards, and the bone fracture plate lower portion is obliquely arranged at the lower end of the bone fracture plate lower portion outwards. The bone fracture plate upper part and the bone fracture plate lower part are detachably connected, the femur comprises a femoral shaft, a femur head, a femoral neck and greater trochanter, a fixing screw is inserted into the bone fracture plate lower part, and the fixing screw is inserted into the femoral shaft. The knee joint self-healing device has the advantages that the containing bag makes contact with the body, then the heating wire works for heating, blood circulation can be promoted through heating, extravasated blood is prevented from being generated at the injured position, self-healing of the knee joint of a patient and recovery of the self-healing function are accelerated, the medicine bag is placed in the containing bag, generated heat is most used for the medicine bag, traditional Chinese medicine in the medicine bag is rapidly volatilized, and the effect is achieved. The cold at the painful part can be removed, so that the effect of relieving the pains is more obvious.

Description

technical field [0001] The invention relates to the medical field, in particular to a bone plate fixing device conforming to the bone healing process. Background technique [0002] In the existing clinical cases, the common ones involving femoral head necrosis are mainly avascular necrosis of the femoral head, which is a pathological process caused by the destruction of the blood supply of the femoral head due to various etiologies, resulting in osteonecrosis of the femoral head. , the body naturally repairs the necrotic area, the necrotic bone trabeculae are gradually absorbed, the mechanical strength of the femoral head decreases, causing collapse and deformation, resulting in serious damage to the hip joint, and the decline in supporting performance. Under load, it can lead to abnormal bearing of the subchondral bone Stress causes the articular surface to collapse, and hip osteoarthritis occurs, which seriously affects the function of the hip joint and affects the quality...
