Description

Technical Field

[0001] The utility model relates to the technical field of medical care, in particular to a patient limb fixing frame. Background Technique

[0002] A patient limb fixing frame is a medical device used to fix a patient's limb. During the treatment of certain diseases, the limb fixing frame can play an auxiliary role. According to the patient's condition and limb condition, a fixing frame of a suitable type and size is selected. If the fixing frame is too large or too small, it may affect the fixing effect and the patient's comfort.

[0003] During the operation, a fixing frame is used to fix the patient's limb. Usually, the fixing distance between the fixing frames is adjusted. When adjusting the length of the fixing frame itself, the staff needs to continuously adjust the fixing frame itself so that the fixing frame can adapt to the length of the patient's limb for fixing work. This adjustment method is relatively cumbersome and time-consuming and laborious. Therefore, we propose a patient limb fixing frame. Content of the Utility Model
