Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for clinical orthopedic surgery. Background Technology

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. When performing surgery on orthopedic patients, it is necessary to support the affected limb. Usually, medical staff lift the affected limb and put a pad under the affected limb for support, which is very troublesome. Therefore, a fixation device is needed to support the affected limb.

[0003] A search revealed an orthopedic clinical surgical assistance device (publication number CN211131950U) comprising a straight groove rod. The device is characterized in that: both ends of the straight groove rod are hinged to the ends of a screw rod; two sliders are embedded in the groove of the straight groove rod; the screw rod is connected to the sliders via two reverse threads; one side of each slider is fixedly connected to a vertical plate; and the upper sides of each vertical plate are fixedly connected to a slide rail. This utility model relates to the field of orthopedic surgical assistance equipment, specifically to an orthopedic clinical surgical assistance device. This device can support the patient's arm or leg during orthopedic surgery. Based on the aforementioned patent, a small screw 14 is connected to a sliding block 13 via two reverse threads. The two sliding blocks 13 move in opposite directions, causing the connecting rod 4 to swing. The connecting rod 4 causes the H-shaped connecting block 3 to move upward, and the H-shaped connecting block 3 causes the arc-shaped support block 2 to move upward. The heights of the two arc-shaped support blocks 2 are adjusted sequentially. However, since the bottom of the arc-shaped support block is directly fixed to the top of the H-shaped connecting block 3, when the two arc-shaped support blocks are not aligned after adjustment, the patient's limb will be squeezed by the edge of the arc-shaped support block with the higher height, forming an indentation, which makes the patient's limb very uncomfortable. In response to this technical problem, this application proposes a fixation device for clinical orthopedic surgery. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixation device for clinical orthopedic surgery. When the height of one side of the patient's limb is changed by the rotation of the second handwheel, causing the one-way screw to move inside the support seat, the rotating block at the bottom of the fixation seat will automatically rotate on the rotating seat, so that the top of the fixation seat can always be in contact with the patient's limb, avoiding the situation where the edge of the fixation seat presses on the patient's limb for a long time after the height changes, causing injury.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fixation device for clinical orthopedic surgery includes a base, a bidirectional screw rotatably connected to the inner wall of the base, sliders threadedly connected to the left and right sides of the outer wall of the bidirectional screw, a support seat fixedly connected to the top of each slider, a connecting plate connected to the inner wall of each support seat via an adjustment component, a rotating seat fixedly connected to the top of each connecting plate, a rotating block rotatably connected to the outer wall of each rotating seat, a fixed seat fixedly connected to the top of each rotating block, and a limit component provided at the top of each fixed seat.

[0006] Furthermore, the outer wall of the slider is slidably connected to the inner wall of the base, and the right end of the bidirectional screw is fixedly connected to the first handwheel.

[0007] Furthermore, the adjustment assembly includes one-way screws threadedly connected to the inner wall of the support base, and a second handwheel is fixedly connected to the top of each one-way screw. The top of each second handwheel is rotatably connected to the middle of the bottom end of the connecting plate.

[0008] Furthermore, telescopic rods are fixedly connected to both the front and rear sides of the top of the support base, and the top ends of the telescopic rods are fixedly connected to the bottom of the connecting plate.

[0009] Furthermore, the limiting component includes multiple grooves on both the left and right sides of the top of the fixed base. A crossbar is fixedly connected to the inner wall of each groove. A fixing ring is provided on the outer wall of each crossbar on the left side. An elastic band is fixedly connected to the right end of each fixing ring.

[0010] Furthermore, each elastic band has a retaining ring fixedly connected to its right end, and the inner wall of each retaining ring is engaged with the outer wall of the right crossbar.

[0011] Furthermore, each of the top inner walls of the fixation base is fixedly connected with a pad, which is used to provide protection for the patient's limbs.

[0012] This utility model has the following beneficial effects: 1. In this utility model, when the height of one side of the patient's limb is changed by the rotation of the second handwheel causing the one-way screw to move inside the support seat, the rotating block at the bottom of the fixed seat will automatically rotate on the rotating seat, so that the top of the fixed seat can always be in contact with the patient's limb, avoiding the situation where the edge of the fixed seat presses on the patient's limb for a long time after the height changes, causing injury.

[0013] 2. In this utility model, when the patient places his / her limb inside the fixation seat, the pad inside the fixation seat will support the patient and deform to fit the patient's limb, improving the patient's comfort. When the retaining ring is engaged with the right crossbar, the elastic band is used to limit the patient's limb and prevent the patient's limb from moving inside the fixation seat and affecting the medical staff's operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-3 An embodiment of this utility model provides a fixation device for clinical orthopedic surgery, comprising a base 1, a bidirectional screw 2 rotatably connected to the inner wall of the base 1, sliders 3 threadedly connected to the left and right sides of the outer wall of the bidirectional screw 2, sliders 3 slidably connected to the inner wall of the base 1, a first handwheel 11 fixedly connected to the right end of the bidirectional screw 2, a support seat 4 fixedly connected to the top of each slider 3, a connecting plate 6 connected to the inner wall of each support seat 4 via an adjustment assembly, the adjustment assembly including a unidirectional screw 12 threadedly connected to the inner wall of the support seat 4, a second handwheel 13 fixedly connected to the top of each unidirectional screw 12, the top of each second handwheel 13 rotatably connected to the middle of the bottom end of the connecting plate 6, telescopic rods 5 fixedly connected to the front and rear sides of the top end of the support seat 4, the top of each telescopic rod 5 fixedly connected to the bottom end of the connecting plate 6, a rotating seat 7 fixedly connected to the top end of each connecting plate 6, a rotating block 8 rotatably connected to the outer wall of each rotating seat 7, and a fixed seat 9 fixedly connected to the top of each rotating block 8. Specifically, the first handwheel 11 drives the bidirectional screw 2 to rotate. Under the action of the thread on the surface of the bidirectional screw 2, the two sliders 3 can move relative to each other or in opposite directions along the surface of the bidirectional screw 2, thereby adjusting the distance between the two fixed seats 9 to suit the limbs of different patients. The second handwheel 13 drives the unidirectional screw 12 to rotate inside the support seat 4, allowing the unidirectional screw 12 to move inside the support seat 4 and adjust the height of the connecting plate 6. The telescopic rods 5 on both sides of the bottom end of the connecting plate 6 are connected to the support seat 4. When the connecting plate 6 moves, the telescopic rods 5 will be stretched and the telescopic rods 5 will limit the connecting plate 6, so that the connecting plate 6 will not rotate with the second handwheel 13. When the connecting plate 6 moves, the rotating block 8 will rotate on the rotating seat 7, so that the fixed seat 9 is always in contact with the patient's limb, avoiding the edge of the two fixed seats 9 being compressed on the patient's limb and causing discomfort when the heights of the two fixed seats 9 are different.

[0018] Each top of the fixation base 9 is provided with a limiting component, which includes multiple grooves 14 on the left and right sides of the top of the fixation base 9. A crossbar 15 is fixedly connected to the inner wall of each groove 14. A fixing ring 16 is provided on the outer wall of each left crossbar 15. An elastic band 17 is fixedly connected to the right end of each fixing ring 16. A retaining ring 18 is fixedly connected to the right end of each elastic band 17. The inner wall of the retaining ring 18 is engaged with the outer wall of the right crossbar 15. A pad 10 is fixedly connected to the inner wall of the top of the fixation base 9. The pad 10 is used to provide protection for the patient's limb. Specifically, when the patient places their limb inside the fixation seat 9, the pad 10 inside the fixation seat 9 will support the patient and deform to fit the patient's limb, improving the patient's comfort. When the retaining ring 18 is engaged with the right crossbar 15, the elastic band 17 is used to limit the patient's limb, preventing the patient's limb from moving inside the fixation seat 9 and affecting the medical staff's operation.

[0019] Working principle: First, rotate the first handwheel 11 according to the length of the patient's limb, so that the bidirectional screw 2 rotates and drives the slider 3 to move inside the base 1, adjusting the distance between the two fixed seats 9 to ensure that the bottom of the patient's limb can be completely placed on the fixed seats 9 on both sides. Then, place the patient's limb on the pad 10 inside the fixed seat 9 and pull the multiple retaining rings 18 on the fixed seat 9 to lock them onto the outer wall of the right crossbar 15. The elastic band 17 limits the movement of the patient's limb to prevent movement during the operation. During the operation, medical staff can rotate the second handwheel 13 at the bottom of the connecting plate 6 according to the position requirements of the operation, so that the unidirectional screw 12 moves inside the support seat 4 to adjust the height of the fixed seat 9, so that the height of the patient's limb as a whole or on one side can be changed to facilitate the operation. When the height of the patient's limb on one side changes, the rotating block 8 at the bottom of the fixed seat 9 will automatically rotate on the rotating seat 7, so that the top of the fixed seat 9 can always be in contact with the patient's limb, avoiding damage caused by the edge of the fixed seat 9 pressing on the patient's limb for a long time after the height is changed.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
