Abstract

The invention provides a pelvic fracture front ring fixing detachable screw and an internal fixing device.The pelvic fracture front ring fixing detachable screw comprises a main screw, a connecting screw and a screw barrel; the tail end of the connecting nail is fixedly connected with the head end of the nail barrel, and the head end of the connecting nail extends out of the nail barrel to be detachably connected with the tail end of the main nail. The internal fixing device comprises a connecting cross rod and at least two detachable screws for fixing the pelvic fracture front ring. The pelvic fracture front ring fixing detachable screws are connected through a connecting cross rod. The problem that in the prior art, for a patient provided with an inner fixing frame, the rest part outside a main screw of a screw is difficult to take out is solved. When the main screw does not need to be taken out, the rest part of the pelvic fracture front ring fixing detachable screw can be taken out, and then the postoperative discomfort of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a detachable screw and an internal fixation device for fixing an anterior ring of a pelvic fracture. Background technique [0002] For the fragile anterior pelvic ring injury in the elderly, minimally invasive anterior pelvic ring internal fixation (Minimally Invasive Anterior Pelvic Ring Internal Fixator) is generally used clinically. The most widely used and most effective device in this operation is called internal fixation frame (INFIX). The original design of the internal fixator is to stabilize the anterior pelvic ring, so injuries to the anterior pelvic ring, including separation of the pubic symphysis and fractures of the pubic ramus, are its best indications. Because the internal fixator is located in the front of the lower abdomen and pelvis, thin patients will experience subjective discomfort, especially for the upright posture. After surgery, subje...
