Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a conservative treatment device for pelvic fractures. Background Art
[0002] When the displacement of pelvic fractures is not obvious or there are surgical contraindications, conservative treatment is often used clinically. At present, a pelvic sling is used for continuous pelvic traction clinically. Since the buttocks are completely suspended and lifted during pelvic traction and continuous traction is required, the patient cannot turn over and move at will, which not only greatly reduces the comfort of the patient; because the pelvic sling does not fix both sides of the patient's pelvis, the suspended patient sometimes sways, and sometimes the swaying will cause the binding force of the pelvic sling to decrease, resulting in poor traction effect and affecting the patient's recovery.
[0003] Therefore, it is necessary to invent a fixing device that can fix the fractured pelvis and is convenient for conservative treatment clinically when the displacement of pelvic fractures is not obvious or there are surgical contraindications. Summary of the Invention
[0004] The purpose of the utility model is to provide a conservative treatment device for pelvic fractures to solve the technical problems that the patient cannot turn over and move, has low comfort and poor traction effect during the treatment of the traditional conservative treatment device for pelvic fractures.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A conservative treatment device for pelvic fractures includes two vertical plates, a distance adjustment structure and two clamping structures. The two vertical plates are arranged in parallel at intervals. The upper parts of the two vertical plates are connected by the distance adjustment structure, and the distance adjustment structure can adjust the distance between the two vertical plates; a clamping structure with an opening facing one side is arranged at the lower part of each vertical plate, and the openings of the clamping structures face each other.
[0007] Further, the clamping structure includes an upper clamping pad, an upper ejector rod, a lower clamping pad and a lower ejector rod. The upper clamping pad is located above the lower clamping pad. The lower end of the upper clamping pad is hinged to the vertical plate. The upper ejector rod is screwed on the vertical plate, and one end of the upper ejector rod can abut against the upper clamping pad; the upper end of the upper clamping pad is hinged to the vertical plate. The lower ejector rod is screwed on the vertical plate, and one end of the lower ejector rod can abut against the lower clamping pad.
[0008] Further, the other ends of the upper ejector rod and the lower ejector rod are both arranged outside the two vertical plates, and first rotating disks are arranged at the outer ends of the upper ejector rod and the lower ejector rod.
[0009] Further, the clamping surfaces of the upper clamping pad and the lower clamping pad are both concave downward.
[0010] Furthermore, the clamping pad further includes an intermediate pad which is located between the upper clamping pad and the lower clamping pad and is fixedly connected to the vertical plate.
[0011] Furthermore, air-permeable soft cushion layers are provided on the clamping surfaces of the upper clamping pad, the lower clamping pad, and the intermediate pad.
[0012] Furthermore, the distance adjustment structure includes a screw rod and a guide rod. One end of the screw rod is rotatably connected to the upper part of one vertical plate, and the other end is screwed to the upper part of the other vertical plate; one end of the guide rod is fixedly connected to the upper part of the vertical plate, and the other end is slidably connected to the upper part of the other vertical plate.

[0016] 1. When the present utility model is in use, by placing the hip of a patient with a pelvic fracture between two clamping structures, and moving the vertical plates towards each other through the distance adjustment structure, the two clamping structures squeeze the hip of the patient, so that the fractured pelvis of the patient is squeezed and constrained to achieve the traction effect on the fractured pelvis of the patient; at this time, the distance adjustment structure is located on the lower abdomen of the patient, and the patient can perform small-amplitude turning activities, improving the comfort of the patient. Moreover, since the entire device is relatively fixed after the distance adjustment structure is adjusted, it is not easy to cause the squeezing of the patient's hip to become smaller, and the traction of the fractured pelvis is stable and reliable. Based on the above, the present utility model can solve the technical problems that in the traditional conservative treatment device for pelvic fractures, the patient cannot turn over and move, the comfort is low, and the traction effect is poor.
[0017] 2. The present utility model is provided with movable upper and lower clamping pads, and the extrusion angle during clamping can be finely adjusted according to the body type or fracture condition of the patient through the upper push rod and the lower push rod, improving the scope of application and the use effect; by providing an intermediate pad, it is prevented that the middle part of the V-shaped structure formed by the upper and lower clamping pads is too concave and causes discomfort to the patient; by providing an air-permeable soft cushion layer and the downward depression of the clamping surface, the comfort of the patient can be further improved.
[0018] 3. The screw rod of the distance adjustment structure of the present utility model can achieve the effect of rotational distance adjustment, and the relative rotation of the two vertical plates can be prevented through the guide rod, improving the reliability; by providing a hollowed-out part in the middle of the vertical plate, the weight of the device can be reduced.
