Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a limb fixing device for an orthopedic operating room comprises an annular support 1 and an arc-shaped fixing plate 4, wherein the annular support 1 is positioned right above a bed body 7, a mattress 8 is arranged on the bed body 7, second through grooves 6 are coaxially arranged on two sides of the annular support 1 and the bed body 7, screw rods 2 are sleeved in the second through grooves 6, the screw rods 2 are in threaded connection with the second through grooves 6, a plurality of sliding blocks 3 are sleeved on the annular support 1, the sliding blocks 3 can slide on the annular support 1 at will and change positions so as to be matched with the placement positions of limbs of a patient to be adjusted, the arc-shaped fixing plate 4 is arranged at the bottom of the plurality of sliding blocks 3, the sliding blocks 3 enable the arc-shaped fixing plate 4 to be positioned right above the positions of the limbs of the patient to be fixed, the screw rods 2 are rotated to drive the annular support 1 to move downwards integrally according to a thread transmission principle until, the friction force between the limb fixing device and the patient is large, so that the limb of the patient is fixed, the limb fixing device is simple in structure, the limb fixing device is not influenced by the position where the limb of the patient is placed, the operation is convenient, and the manufacturing cost is low.

Specifically, as shown in fig. 2, the bottom of the sliding block 3 is rotatably connected with the top of the arc-shaped fixing plate 4 through a spherical hinge 401, so that the arc-shaped fixing plate 4 can freely rotate around the central line thereof, and can be matched with the limb placement position of a patient to be subjected to micro-adjustment, so that the limb of the patient is fixed more stably and more reliably, and meanwhile, the fixing position of the.

Specifically, as shown in fig. 2, a first through groove 402 has been seted up on one side of arc fixed

plate

4, 4 inner wall one side elastic connection of arc fixed plate has elastic cord 5, the other end of elastic cord 5 runs through first through groove 402, the patient limb is fixed in arc fixed plate 4, outwards stimulate elastic cord 5, further fixed patient limb, improve fixed effect, treat after fixed, make an end of rope with elastic cord 5 extension end, the internal diameter of first through groove 402 slightly is greater than elastic cord 5 external diameter, guarantee that the end of rope can not slide into first through groove 402, influence fixed effect.

The working principle is as follows: when the device is used, a patient lies on the mattress 8, the sliding block 3 on the annular support 1 is slid to be positioned right above the position where the limb of the patient needs to be fixed, the screw rod 2 is rotated, the annular support 1 moves downwards according to the thread transmission principle to further drive the arc-shaped fixing plate 4 to move downwards until the arc-shaped fixing plate 4 is tightly pressed on the mattress 8, the preliminary fixing of the limb of the patient is completed, due to the effect of the spherical hinge 401, the arc-shaped fixing plate 4 can freely rotate around the central line of the arc-shaped fixing plate, the micro-adjustment is carried out by matching with the position where the limb of the patient is placed, so that the limb of the patient is fixed more stably and firmly, due to different thicknesses of the limbs of the patient, the preliminary fixing is sometimes not firm, if the fixing is not firm, the elastic band 5 is pulled outwards to further fix the limb of the patient, the fixing effect is, no further fixation is necessary.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
