[0020] Embodiment one

[0021] Figures 1-2 An orthopedic surgical positioning device is schematically shown.

[0022] As Figure 1 shown, the embodiment provides an orthopedic surgical positioning device, which comprises an arc-shaped rod 1, further comprises two leg fixing claws 2 oppositely arranged in the arc-shaped rod 1;

[0023] The leg fixing claw 2 can clamp and fix the leg, and when the two oppositely arranged leg fixing claws 2 are close to each other, the leg is clamped, so that the operation can be better performed during the orthopedic surgery of the leg, the sliding of the leg affecting the operation is avoided, and the operation confidence of the doctor is also increased, and the situation that the patient's leg moves randomly does not need to be considered;

[0024] Two push rods 3 are arranged in the arc-shaped rod 1 and connected with the corresponding leg fixing claws 2 and move to drive the corresponding fixing claws to move to fix the legs;

[0025] When the legs are clamped, the corresponding push rod 3 can be controlled to drive the leg fixing claws to move, thereby realizing clamping of the legs of different patients, avoiding that the same device cannot adapt to different situations when legs of different thicknesses appear, and increasing the practicality of product use;

[0026] The handle 4 is slidably connected with the arc-shaped rod 1;

[0027] By arranging the handle 4 on the side of the arc-shaped rod 1, the doctor can hold the handle 4 with one hand to apply a fixed force to the patient during orthopedic surgery after clamping the legs, and the doctor can fix the product with one hand during the surgery to fix the patient's legs, so that the patient's legs can be operated more reliably, and the stability of the patient's legs is improved, so that the doctor can adjust the placement position of the patient's legs slightly according to the needs of the surgery.

[0028] As shown in Figure 1 The arc-shaped rod 1 is symmetrically provided with a threaded hole 11, the push rod 3 is threadedly connected with the threaded hole 11, the push rod 3 is connected with the leg fixing claw through a connecting block 31, the connecting block 31 is rotationally connected with the push rod 3, and the connecting block 31 is provided with at least one set of connecting limit rods 32, and the limit rods 32 are arranged to penetrate through the arc-shaped rod 1 and are slidably connected with the arc-shaped rod 1.

[0029] In this embodiment, when the push rod 1 is rotated, the threaded connection between the push rod 1 and the threaded hole 11 can drive the leg fixing claw 2 to move. In order to ensure that the leg fixing claw 2 does not deviate in angle when moving, the limit rods 32 are additionally arranged on the connecting block 31, which can ensure that the connecting block can only move left and right and cannot rotate, so that the legs can be clamped by placing the legs on the moving path of the two leg fixing claws 2 before use.

[0030] As shown in Figure 1 The leg fixing claw 2 includes a leg fixing claw one 21 and a leg fixing claw two 22, the leg fixing claw one 21 and the leg fixing claw two 22 are rotationally connected, the connecting block 31 is provided with a rotating groove 35, and the leg fixing claw one 21 and the leg fixing claw two 22 are rotationally connected with the rotating groove 35, respectively.

[0031] In this embodiment, the leg fixing claw one 21 is rotatably connected with the leg fixing claw two 22, and a torsion spring is arranged between the two. Under the pushing of the push rod 3, the two groups of leg fixing claws are close to each other until the leg clamping. When a patient with a larger leg size is encountered, the leg fixing claw one 21 and the leg fixing claw two 22 rotate when they touch the leg, so that the leg fixing claw one 21 and the leg fixing claw two 22 are opened, thereby realizing the adaptation to different sizes of legs and increasing the practicability of the product.

[0032] In combination Figure 2 As shown, the connecting block 31 is internally provided with a rotating groove 33, and the rotating groove 33 is internally provided with a rotating block 34 which is fixedly connected with the push rod 3.

[0033] In this embodiment, in order to ensure that the push rod 3 and the connecting block 31 are not disconnected when they rotate relative to each other, the rotating block 34 is designed as a T-shaped embedded in the connecting block 31.

[0034] In combination Figure 1 As shown, the limiting rod 1 is provided with two groups, and the two groups of limiting rods are symmetrically arranged.

[0035] In this embodiment, the arrangement of the two groups of limiting rods 13 can further increase the lateral stability performance when the leg fixing claw 2 moves.

[0036] In combination Figure 1 As shown, the arc-shaped rod 1 is provided with an arc-shaped groove 11, the arc-shaped groove 11 is internally provided with an arc-shaped sliding block 12, the arc-shaped sliding block 12 has the same curvature as the arc-shaped groove 11, the handle 4 is arranged on the arc-shaped sliding block 12, the arc-shaped sliding block 12 is internally provided with a threaded hole 41, a jacking rod 42 is threadedly connected in the threaded hole 41, and the jacking rod 42 abuts against the groove bottom of the arc-shaped sliding block 12 and the arc-shaped groove 11.

[0037] In this embodiment, the arc-shaped sliding block 12 can smoothly slide in the arc-shaped groove 11 because the arc-shaped groove 11 has the same curvature as the arc-shaped sliding block 12, so that the phenomenon of being stuck is avoided. In order to ensure that the handle 4 can be smoothly fixed on the arc-shaped rod 1, the threaded hole 41 is arranged in the interior of the handle 4. Through the arrangement of the threaded hole 41, the jacking rod 42 can be screwed up and down, so that the handle 4 can be fixed at any position of the arc-shaped rod 1. The handle 4 can be adjusted to the appropriate position according to the different surgical positions, so that the doctor can comfortably hold the handle 4, and the practicability of the product is improved.

[0038] In combination Figure 1 As shown, the push rod 3 is fixedly connected with a screw head 5 at the end away from the leg fixing claw 2.

[0039] In the embodiment, the rotating screw head 5 can drive the push rod 3 to rotate, in order to further increase the convenience of the screw head 5, anti-skid convex points are arranged on the circumferential side of the screw head 5, and the anti-skid convex points can increase the rotation efficiency of the screw head 5.

[0040] Working steps

[0041] In use, the legs are placed between the two groups of leg fixing claws 2, then the rotating screw head 5 drives the push rod 3 to rotate, the push rod 3 drives the connecting block 31 and the leg fixing claws 2 to move through thread cooperation, so as to clamp the legs, when encountering a larger size leg, the leg fixing claw one 21 and the leg fixing claw two 22 abut against the leg, so that the leg fixing claw one 21 and the leg fixing claw two 22 rotate and separate, the opening is enlarged, and then the larger patient with legs is adapted, after the two groups of leg fixing claws 2 fix the legs, the handle 4 is slid to the desired position, then the top rod 42 is screwed to make the top rod 42 abut against one side of the arc-shaped rod 1, so as to fix the position of the handle.

[0042] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
