Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a height adjusting device for an affected limb. Background Art

[0002] During lower limb surgeries, due to the delicacy and complexity of the surgical procedures, precise position control of the affected limb is of particular importance. To optimize the surgical field of view and ensure the smooth progress of the surgical operation, it is often necessary to adjust the height and angle of the affected limb according to the specific requirements of the surgery. Currently, the methods widely used in clinical practice include folding sterile drapes to elevate the affected limb or using wooden blocks for this purpose. However, both of these methods have certain limitations and deficiencies.

[0003] Using the method of folding sterile drapes, although simple and easy to implement, can meet the need for elevating the affected limb to a certain extent, its limitations are also obvious. When the number of sterile drapes on the operating table is limited, it is difficult to achieve the ideal elevation height and angle through simple folding, which may affect the accuracy and efficiency of the surgery. More troublesome is that in the case of insufficient sterile drapes, it is necessary to open a new sterile pack for supplementation, which undoubtedly increases the disinfection and sterilization costs during the surgery and also prolongs the surgical preparation time.

[0004] On the other hand, using a wooden block to elevate the affected limb, although stable and reliable, also has problems that cannot be ignored. Although the wooden block can be used in surgery after strict cleaning, disinfection, and sterilization processes, its wooden material is often easily damaged after multiple such treatments, resulting in a greatly shortened service life. In addition, in order to stabilize the wooden block, metal wires are usually tied to both sides of it, and these metal components will produce imaging during intraoperative fluoroscopy, causing unnecessary interference to the surgeon's observation of intraoperative images and affecting the accuracy of surgical judgment.
