Description

Technical Field

[0001] This utility model relates to the field of orthopedic surgeons, specifically to a tibial tuberosity traction device for patients with osteoporosis. Background Technology

[0002] Orthopedic surgeons often place a tibial tuberosity traction device at the tibial tuberosity when treating osteoporosis patients. However, existing traction devices are prone to slippage of the connector, affecting tibial traction treatment. Therefore, designing a new tibial tuberosity traction device for osteoporosis patients is crucial. For example: A tibial tuberosity traction device for osteoporosis patients, disclosed in Chinese Patent Publication No. CN112137704B, includes a traction bow, a first traction needle, and a second traction needle. The second traction needle is located below the first traction needle and is arranged horizontally, intersecting the first traction needle to form a preset horizontal angle α. The traction bow is connected to the first traction needle, and two adjustable rods of adjustable length are provided between the first and second traction needles. Each adjusting rod is equipped with a universal ball, and the adjusting rod is rotatably connected to the first and / or second traction needles through the universal ball.

[0003] However, the existing technical solutions have the following drawbacks: they are not convenient to prevent the slippage of the tibial tuberosity traction device connector in osteoporosis patients, and at the same time, they are not convenient to adjust the horizontal spacing of the tibial tuberosity traction device in osteoporosis patients. Therefore, this utility model provides a tibial tuberosity traction device for osteoporosis patients to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a tibial tuberosity traction device for osteoporosis patients, in order to solve the problems mentioned in the background art, such as the difficulty in avoiding slippage of the tibial tuberosity traction device connector head and the difficulty in adjusting the horizontal spacing of the tibial tuberosity traction device for osteoporosis patients.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tibial tuberosity traction device for osteoporosis patients, comprising a traction frame, a connecting rod at the bottom end of the traction frame, a connecting head body on the outside of the connecting rod, a traction needle disposed inside the connecting head body, a needle sleeve installed on the outside of the traction needle, a limiting assembly disposed on the outside of the traction needle, and a limiting block disposed on the outside of the traction needle. A limiting rod is installed inside the limiting block, and a limiting wheel is installed on the outer side of the limiting rod. An adjusting rod is provided on the inner side of the traction frame, and a positioning plate is provided on the outer side of the adjusting rod. A traction block is installed on the outer side of the adjusting rod, and a positioning groove is opened inside the traction block. A connecting block is installed on the upper side of the traction block, and a connecting block is installed on the outer side of the traction block. A connecting bolt is connected inside the connecting block.

[0006] Preferably, the connecting rod is threadedly connected to the connector body, and the traction pin passes through the interior of the connector body.

[0007] Preferably, the connector body is symmetrically arranged about the center line of the traction needle, and the traction needle and the needle sleeve are engaged and connected.

[0008] Preferably, the limiting blocks are arranged symmetrically about the center line of the connector body, and the limiting rod passes through the interior of the limiting blocks.

[0009] Preferably, the limiting rod and the limiting wheel are threadedly connected, and the limiting wheel is symmetrically arranged about the center line of the limiting rod.

[0010] Preferably, the positioning plate is slidably connected to the traction block via a positioning groove, and the diameter of the adjusting rod is smaller than the diameter of the traction block.

[0011] Preferably, the connecting bolt and the connecting block are threadedly connected, and the connecting blocks are symmetrically arranged about the center line of the traction block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This tibial tuberosity traction device for osteoporosis patients, by adding a limiting assembly, allows the limiting rod to pass through the traction needle and the limiting block, and the limiting block to limit the position of the connecting head body. Compared with the traditional technology, it can prevent the connecting head of the tibial tuberosity traction device for osteoporosis patients from sliding. At the same time, the addition of a connecting bolt and a positioning plate makes it easy to adjust the horizontal spacing of the tibial tuberosity traction device for osteoporosis patients. The specific operation is as follows; 1. It is equipped with a limiting assembly and a connector body. By superimposing a limiting block on the outside of the connector body, a limiting rod is passed through the inside of the limiting block, and the upper and lower ends of the limiting rod are threadedly connected to the limiting wheel, so that the position of the connector body on the traction needle is limited, which helps to prevent the tibial tuberosity traction device connector from slipping in patients with osteoporosis. 2. It is equipped with a traction needle and a needle sleeve. The connector body is symmetrically arranged on the left and right sides about the center line of the traction needle, and the traction needle and the needle sleeve are locked together. After the traction needle is installed on the tibia, the needle sleeve can protect the left and right ends of the traction needle. Furthermore, by tightening the connecting bolts inside the connecting block, the connecting block and the positioning plate are connected through the connecting bolts, and the horizontal spacing of the traction frames at both ends is fixed, which makes it easy to adjust the horizontal spacing of the tibial tuberosity traction device for osteoporosis patients.

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a tibial tuberosity traction device for osteoporosis patients, including a traction frame 1, a connecting rod 2 at the bottom end of the traction frame 1, a connecting head body 3 on the outside of the connecting rod 2, a traction needle 4 inside the connecting head body 3, a needle sleeve 5 installed on the outside of the traction needle 4, a limiting assembly 6 on the outside of the traction needle 4, and the limiting assembly 6 including a limiting block 601 on the outside of the traction needle 4. A limiting rod 602 is located inside the limiting block 601, and a limiting wheel 603 is installed on the outer side of the limiting rod 602. An adjusting rod 7 is provided on the inner side of the traction frame 1, and a positioning plate 8 is provided on the outer side of the adjusting rod 7. A traction block 9 is installed on the outer side of the adjusting rod 7, and a positioning groove 10 is opened inside the traction block 9. A connecting block 11 is installed on the upper side of the traction block 9, and a connecting block 12 is installed on the outer side of the traction block 9. A connecting bolt 13 is connected inside the connecting block 12. The combination constitutes a tibial tuberosity traction device for patients with osteoporosis.

[0017] like Figure 1 , Figure 3 and Figure 4 As shown, the connecting rod 2 is threadedly connected to the connector body 3, and the traction pin 4 passes through the interior of the connector body 3. The connector body 3 is symmetrically arranged about the center line of the traction pin 4, and the traction pin 4 is engaged with the pin sleeve 5. The limiting block 601 is symmetrically arranged about the center line of the connector body 3, and the limiting rod 602 passes through the interior of the limiting block 601. The limiting rod 602 is threadedly connected to the limiting wheel 603, and the limiting wheel 603 is symmetrically arranged about the center line of the limiting rod 602. After the traction needle 4 passes through the tibia and is perpendicular to the longitudinal axis of the tibia, a limiting block 601 is nested at both ends of the traction needle 4, so that after the traction needle 4 passes through the connector body 3, another limiting block 601 is superimposed on the outside of the connector body 3. The limiting rod 602 passes through the inside of the limiting block 601, and the upper and lower ends of the limiting rod 602 are threadedly connected to the limiting wheel 603, so that the position of the connector body 3 on the traction needle 4 is limited, which helps to prevent the tibial tuberosity traction device connector from slipping in patients with osteoporosis.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning plate 8 is slidably connected to the traction block 9 through the positioning groove 10, and the diameter of the adjusting rod 7 is smaller than the diameter of the traction block 9. The connecting bolt 13 is threadedly connected to the connecting block 12, and the connecting block 12 is symmetrically arranged about the center line of the traction block 9. Before the connecting head body 3 is penetrated by the traction needle 4, the connecting head body 3 is threadedly connected to the connecting rod 2 at the lower end of the traction frame 1, so that the traction frame 1 is connected to the connecting head body 3 through the connecting rod 2. The positioning plate 8 on the outside of the adjusting rod 7 slides in the positioning groove 10 opened inside the traction block 9. When the distance between the left and right ends of the traction frame 1 is appropriate, the connecting bolt 13 inside the connecting block 12 is tightened, so that the connecting block 12 and the positioning plate 8 are connected through the connecting bolt 13. The horizontal distance between the left and right ends of the traction frame 1 is fixed, which makes it easy to adjust the horizontal distance of the tibial tuberosity traction device for osteoporosis patients. This is the method of using the tibial tuberosity traction device for osteoporosis patients.
