Abstract

The invention provides a minimally-invasive four-limb fracture three-dimensional traction restoring and fixing device which comprises a first fixing assembly. The first fixing assembly comprises a first fixing ring, a first supporting block, a first spherical hinge support and a first thread needle. The first supporting block is detachably connected to the first fixing ring. The first spherical hinge support is located on one side of the first fixing ring. One end of the first spherical hinge support is fixedly connected with the first supporting block, and the other end of the first sphericalhinge support is detachably connected with the first thread needle. The first fixing assembly further comprises a second supporting block, a second spherical hinge support and a second thread needle.The second supporting block is detachably connected to the first fixing ring. The second spherical hinge support is located on the other side of the first fixing ring. One end of the second sphericalhinge support is fixedly connected with the second supporting block. The other end of the second spherical hinge support is detachably connected with the second thread needle. The adjustment efficiency of the position and posture of the thread needles can be improved, and the fracture restoring process can be conducted through a minimal incision.

Description

technical field [0001] The invention belongs to the technical field of fracture reduction, in particular to a minimally invasive three-dimensional traction reduction and fixation device for extremity fractures. Background technique [0002] External fixation is a method of treating bone and joint injuries and correcting skeletal deformities by attaching bones to devices outside the body to immobilize the injured limb. In the early stage of the operation, the doctor first performs an open reduction on the fracture and then performs the operation. Due to a series of operations, the reduction of the fracture block is often lost, which increases the difficulty of the operation or even fails. A structure is needed to improve it, that is, minimally invasive limb fractures. Three-dimensional traction reduction and immobilization device. [0003] Chinese invention patent CN204971527U discloses an external fixator, which includes two parts of the fixed assembly, the two parts of the...
