Description

Technical Field

[0001] The invention relates to an operating position support frame, in particular to a foldable multifunctional operating position frame suitable for supporting and fixing limb fractures in orthopedic surgery, belonging to the technical field of medical device design. Background Art

[0002] Limb fractures are common in traumatic orthopedic diseases, and are mostly caused by violence, such as falls, blunt injuries, and car accidents. There are many treatment methods for limb fractures in clinical practice, and the more commonly used ones are internal fixation treatment and external fixation treatment. However, no matter what treatment method is used, the patient's limbs need to be reliably supported and fixed to obtain a suitable surgical position. In lower limb surgery, in order to cooperate with the surgical position, the patient's knee joint sometimes needs to be kept in a flexed state, and the flexion angle can be between 30 and 120°. In addition, the length of the calf of different patients will also be different, which also requires the surgical support frame to be able to adapt. However, since the commonly used surgical support frame is a fixed form, its applicability is poor. Sometimes, in order to reliably fix the patient's calf, it is necessary to specially equip a dedicated person to fix the calf, which not only wastes medical resources, but also squeezes the surgical operation space. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a foldable multifunctional surgical position frame, which has an ingenious structure, reasonable design, and is easy to use. It can be folded at multiple angles and can be telescopically fixed, thereby providing auxiliary support for patients with calves of different lengths, and can allow the patient's knee flexion angle to be flexibly adjusted within the range of 30 to 120 degrees, which can free up a surgical staff member who specializes in fixing the calf, and provide the surgeon with the necessary surgical position.
