Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a leg fixing clamp for surgery. Background Art

[0002] The design of the surgical leg fixation clamp is based on the principles of mechanics and biomechanics. The clamp can firmly fix the patient's legs while keeping them at the appropriate angle and position, which helps to reduce movement and vibration during surgery and improve the accuracy and safety of the surgery.

[0003] In the Chinese patent with publication number CN113855460A, a leg fixing clamp for orthopedic surgery is mentioned, which includes a long strip through slot opened in the bed board, a long strip bracket rotatably arranged in the through slot, a first support device arranged in the bracket, and a second support device arranged in the bracket; the rotation axis of the bracket is parallel to the length direction of the bracket; the first support device includes a first support rod and a first support plate arranged at the upper end of the first support rod; the first support rod is rotatably connected to the bracket, and the first support rod is slidably connected to the bracket; the second support device includes a vertically arranged second support rod, and a second support plate arranged at the upper end of the second support rod; the second support rod is slidably connected to the bracket. The leg fixing clamp for orthopedic surgery of the present invention can not only stably fix the patient's legs, but also adjust the patient's legs in various heights and angles.
