Description

A kind of see-through posture combination cushion

technical field

The invention relates to the technical field of orthopedic surgery, in particular to a see-through posture combination pad.

Background technique

Lower extremity fractures occur frequently in clinical practice, and internal fixation surgery is often required. Intraoperative fluoroscopy has a great impact on the final surgical effect of internal fixation. It can immediately confirm the fracture reduction, alignment, position, and appropriateness of internal fixation specifications. And make timely adjustments for possible secondary injuries caused by internal fixation (such as screw penetration into the joint, screw breakage, etc.). However, in the current clinical fluoroscopy of lower extremity fractures, the fluoroscopy position is not good (external rotation of the lower limbs, the height of the affected limb is not high enough to be blocked by the healthy limb during fluoroscopy, and the foot is drooping), and the C-arm machine is easily contaminated during the adjustment process. The movement of the lower limbs affects the temporary fixation of fractures and other issues. In addition, for some special operations (distal femoral fracture internal fixation, patella fracture internal fixation, tibial intramedullary nailing, etc.), it is often necessary to raise the lower limbs and adjust the knee joint to different angles (about 30- 100°), at present clinically commonly used sterilized cloth towels are bundled and padded, and the accuracy is not high, and the pad needs to be adjusted repeatedly during the operation, which affects the operation. Finally, swelling of affected limbs after lower extremity fractures is very common. Rapid swelling reduction is not only beneficial to postoperative pain relief, but also conducive to wound healing, avoiding deep vein thrombosis of lower extremities, and at the same time, it can help patients recover early and shorten hospitalization time and hospitalization costs. There are many ways to reduce swelling, the simplest and most effective of which is that the affected limb is too high. Currently, pillows are often used in clinical practice. The comfort and stability are not good, and the height is not easy to control. Based on the above three points, we design such a fluoroscopy body position combination pad. When fluoroscopy is required during the operation, when the affected limb is fixed on the fluoroscopy pad, it can avoid the left and right rotation of the lower limbs and the blocking of the healthy side, and provide accurate stability when certain operations need to maintain special positions. The body position does not affect the fluoroscopy, and the rapid detumescence and rehabilitation after lower limb surgery can also be achieved through this combination pad. Therefore, we believe that the design of this fluoroscopy body position combination pad is simple and easy to operate, with extensive functions and great clinical application value.
