Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a leg supporting and fixing device. Background Art

[0002] When patients undergo leg surgery, it is difficult for them to adjust and maintain the appropriate surgical angle and posture on their own. If medical staff are required to support and fix the patient's leg position, more medical staff will be needed. Therefore, some support structures are currently used to maintain the patient's basic posture.

[0003] For example, Chinese patent CN110974595B discloses a leg support device for orthopedic surgery, which is provided with a lying plate, which is connected to the left support plate and the right support plate respectively through cylindrical pins; the left support plate is formed by nesting a movable plate and a fixed plate, and a card slot is provided on the movable plate; by setting the movable plate, the horizontal length of the device can be changed.

[0004] However, in some actual surgeries, the posture that the patient needs to maintain for a long time only requires support for the feet and thighs, and there are situations during the operation where the patient's legs need to be moved appropriately; and when moving the legs, excessive pulling on the patient needs to be avoided.

[0005] Based on this, the present invention designs a leg support fixing device to solve the above problems. Utility Model Content

The support roller 5 is a retractable rod structure, and the overall length of the support roller 5 can be manually adjusted to facilitate foot support.

[0035] The mounting locking assembly 21 is configured as a clamping structure consisting of a screw and a handle. The bottom ends of the two screws are threaded through the tops of the first mounting block 2 and the second mounting block 3 and can abut against the mounting plate 1. The top ends of the two screws are fixed with handles for easy rotation.

[0036] Preferably, the support plate 9 is configured as an arc-shaped plate, and the lower edge of the support plate 9 is flush with the operating table.

[0037] In this embodiment, when the leg support fixing device is working normally, after the first mounting block 2 and the second mounting block 3 are installed on the mounting plate 1, the first mounting block 2 and the second mounting block 3 are respectively fixed by two mounting locking components 21, so that the device is easy to install; one end of the connecting rod 51 is inserted into the first adjustment component 4, and the position and angle of the support roller 5 are adjusted to adapt to patients of different heights so that the patient's feet are stepped on the support roller 5; the height of the rotation adjustment component 62 is adjusted by the vertical adjustment component 61, and the distance of the bending adjustment component 8 from the edge of the operating table is adjusted by the rotation adjustment component 62, and the support plate 9 is rotated and adjusted by the bending adjustment component 8, so that the support plate 9 can be suitable for patients of different body shapes through the vertical adjustment component 61, the rotation adjustment component 62 and the bending adjustment component 8, and can be adjusted according to surgical requirements.

[0038] In actual use, the patient's feet are supported by the support rollers 5, and the outside of the patient's thigh root is supported by the support plate 9, so that the patient's legs can be supported during surgery, and at the same time, serious displacement of the patient when the medical staff pulls the patient's legs during the operation can be avoided; and by setting the support plate 9 as an arc plate, the support plate 9 can provide more comprehensive support to the outside of the patient's thigh root, avoiding the patient's legs from detaching from the support plate 9 when moving.

[0039] Example 2

[0040] like Figure 1-5As shown, as a preferred embodiment of the present invention, the first adjusting assembly 4 includes a fixed block 41, a through slot 42, a threaded rod 43 and a rotating rod 44.
