Background
In the trauma orthopaedics of hospitals, fracture patients are the most common, and fracture sites of fracture patients are also various. One of the fracture is pelvic fracture, because of the complex pelvic structure of a human body, the peripheral important vascular nerves are rich, the external iliac veins and obturator nerves run, and the fracture is difficult to appear after the pelvic fracture, and the pubic symphysis separation symptom is a soft tissue injury disease caused by the tiny displacement of the fibrocartilage of pubic bones at two sides due to the external force and other factors, so that pain and difficulty in lifting lower limbs occur locally. The disease can be caused by traumas such as car accidents, falling injuries and the like, and is also common for women in gestational periods. The traditional treatment method for pubic symphysis separation is that the operation is reset and is fixed by pelvic pocket suspension or annular adhesive tape and bellyband, the defects are as follows: patients with severe pubic separation have poor resetting effect; the pressing force is insufficient, the fixation is not firm enough, and the healing is not facilitated; bedsores are easy to generate, and great difficulty is caused to nursing; the patient is in bed for a long time in passive posture, has venous embolism, is uncomfortable and difficult to excrete, and is painful and not easy to accept psychologically. Therefore, in view of the shortcomings of the traditional treatment, the pubic separation is treated by adopting the operation in recent decades in China, and a good treatment effect is achieved, namely in clinic, when the pubic separation is more than 1 cm, the operation is needed to be adopted for treatment, and early incision and reduction are required, and the purpose of healing is achieved by using strong internal fixation traction. Whether the fixing is performed by adopting the adjusting screw or the steel plate, the fixing and treatment effects cannot be optimized, the adjusting screw is easy to break and needs secondary operation, physiological and psychological double pains are brought to a patient, and the adjusting screw is too hard in material and has poor matching to the toughness and bending of bones.
The following problems exist in the prior art:
1. the existing pubic separation fixer for relieving pubic separation is not stable enough in fixation, and can easily cause movement, looseness and even fracture between the bone fracture plate and the pubic combination fixing hook;
