Pelvic repositor and use method thereof

Abstract

The invention relates to a pelvis repositor and a use method thereof. The pelvis repositor comprises a left fixing frame and a right fixing frame, wherein the left fixing frame and the right fixing frame are connected together through an opening and closing angle adjusting mechanism; the end of the left fixing frame and the end of the right fixing frame are respectively connected with a ball head universal rod; the end of the right fixing frame is connected with the ball head universal rod through a pushing adjusting mechanism; an outer sleeve is fixedly mounted at the end of each ball head universal rod; each outer sleeve is used for installing a bone nail inner sleeve or a pressing plate assembly; the pushing adjusting mechanism is used for enabling the ball head universal rod on one side to be close to the ball head universal rod on the other side so as to drive the bone nails or the pressing plate assemblies on two sides to conduct fine adjustment and pressurization on the pelvis; or the ball head universal rod on one side is far away from the ball head universal rod on the other side so as to drive the bone nails or the pressing plate assemblies on the two sides to relieve the fine adjustment and pressurization on the pelvis. The pelvic repositor is not single in function, the pelvic repositor provided with the bone nail inner sleeves meets the use scene of an operating room, and the pelvic repositor provided with the pressing plate assemblies meets the use scene of first aid.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pelvic reset device and its usage method. Background technique [0002] The pelvic structure is composed of the left and right hip bones, sacrum and coccyx bone. When the human pelvis is accidentally collided, the pelvis will be fractured, and there will be damage such as gaps between the left and right hip bones and the sacrum. Bleeding will occur and be life-threatening, which requires timely hemostasis treatment. [0003] At present, in clinical emergency treatment, the patient's hip is usually bound and fixed with bandages, so as to stabilize the pelvis and avoid massive blood loss, and then the patient will be treated after arriving at the hospital. There is a bone nail on each side of the nail, and then a C-shaped pelvic external fixator is used to clamp the bone nails on both sides to reset and fix the pelvis, and then it is convenient for the doctor to carry out the next...

Problems solved by technology

For example, the patent with the authorized announcement number of CN205493973U: a pelvic annular forceps for temporary fixation, and the patent with the authorized announcement number of CN204379421U: a special guide device for the pelvis. For reset and fixation, this kind of pelvic positioning device has the following disadvantages: 1. The application scene is single, and it cannot be applied to emergency hemostasis; 2. After the pelvis is positioned, it cannot be fine-tuned, resulting in inaccurate pelvic reset and pressurization; 3. C-type pelvis The two ends of the fixation frame are not 360-degree movable and adjustable, so that when it clamps the bone nail, it will cause the bone nail to shift, thus affecting the accuracy of the pelvic reduction
