Description

Technical Field

[0001] This utility model relates to the field of orthopedic nursing technology, specifically to an orthopedic traction C-type weight protection device. Background Technology

[0002] In conservative orthopedic treatment, skeletal traction is one method. Skeletal traction involves inserting Kirschner wires, Steinmann wires, or towel clamps into the bone to apply traction to a specific part of the body. This traction force acts directly on the bone, achieving repositioning and fixation. It is commonly used for traction of the skull, olecranon of the ulna, supracondylar femur, tibial tuberosity, and calcaneus. After skeletal traction surgery, a weight is often used for counterweight application.

[0003] Chinese utility model patent document CN210991002U discloses a weight storage device, including a base with a cushioning pad and inserts. The base has four protective rods on its top, each with a threaded head (first and second) at one end. The inserts, each with a weight, have male threads on one side. In use, the inserts are first screwed into the appropriate positions in the threaded grooves of the base. Then, the four protective rods are screwed onto the base using the first threaded head. Next, the top cover is aligned with the four second threaded heads and inserted, and nuts are used to secure the top cover to the protective rods. Finally, the weights are threaded through the gaps between the protective rods onto the inserts. In other words, the weights are stacked sequentially from bottom to top during use. In practical use, to make the counterweight closer to the required counterweight, weights of different weights are often combined. When the counterweight needs to be adjusted, if one of the weights on the pin needs to be replaced, all the weights above that weight must be removed one by one before the weight can be removed. This makes it relatively inconvenient to replace the weights near the base.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] Example 1 like Figures 1-2As shown, this embodiment provides an orthopedic traction C-type weight protection device, including a main body. The main body includes a vertically arranged central rod 10, a hook 11 fixed to the upper end of the central rod 10, an upper cover 12 fixed to the upper part of the central rod 10, a lower tray 14 disposed at the lower part of the central rod 10, and a plurality of guide trays 13 disposed between the upper cover 12 and the lower tray 14. The guide trays 13 are arranged at intervals along the length direction of the central rod 10. The horizontal plane where the plate body 15 of each guide tray 13 is located serves as the dividing interface, dividing the weight placement space into several zones.

[0020] The lower tray 14 and each guide tray 13 include corresponding tray bodies 15 and guide plates 16. Each tray body 15 is horizontally arranged, and the middle portion of each tray body 15 is fixedly connected to a central rod 10. In this embodiment, each tray body 15 has a central through hole in its middle portion, and the central rod 10 passes through the central through hole of each tray body 15. The central through hole of each tray body 15 is fixedly connected to the central rod 10. Each guide plate 16 is vertically arranged and installed on the upper end of the corresponding tray body 15.

[0021] A space for placing a weight is formed between the upper cover 12 and the lower tray 14 for installing a C-type weight.

[0022] In this embodiment, each guide plate 16 is detachably connected to the corresponding disc 15 by screws. Taking the connection structure between one guide plate 16 and the corresponding disc 15 as an example, the screw includes a screw rod and a screw cap fixed to one end of the screw rod. The disc 15 has a through hole. The end of the screw rod away from the screw cap passes through the through hole of the disc 15 from below and upwards and is screwed to the lower end of the guide plate 16. The screw cap abuts against the lower end of the disc 15, thereby detachably connecting the guide plate 16 to the corresponding disc 15.

[0023] A limiting baffle 20 is provided on one side of the main body of the device; each guide plate 16 is located on the side of the central rod 10 away from the limiting baffle 20, and each guide plate 16 is located on the same axial plane of the central rod 10.

[0024] To improve the stability of each guide plate 16, in this embodiment, each guide plate 16 is detachably connected to the center rod 16. Specifically, each guide plate 16 has a slot on the side near the center rod 10, and each slot is arranged horizontally. The center rod 10 has a rod at the position corresponding to each slot, and each rod is arranged horizontally and inserted into the corresponding slot.

[0025] The lower end of the limiting baffle 20 is hinged to the disc body 15 of the lower tray 14, and the upper end of the limiting baffle 20 is detachably connected to the upper cover 12. The limiting baffle 20 is provided with several abutting components, and each abutting component is arranged in a corresponding manner to each partition.

[0026] In this embodiment, the limiting baffle 20 includes a strip plate 21 and a connecting block 22. One end of the strip plate 21 is hinged to the outer periphery of the disc body 15 of the lower tray 14, and the other end of the strip plate 21 is hinged to the connecting block 22. The upper cover 12 has an internal threaded hole at its upper end. The connecting block 22 has a through hole directly above the internal threaded hole, and a locking bolt 23 is provided on the through hole. The locking bolt 23 includes a first screw and a first nut. One end of the first screw is fixedly connected to the first nut, and the other end of the first screw passes through the through hole from above and downwards and is screwed to the internal threaded hole. The first nut abuts against the connecting block 22.

[0027] When it is necessary to remove the connecting block 22 of the limit baffle 20 from the upper cover 12, simply rotate the locking bolt 23 to separate the locking bolt 23 from the internal threaded hole of the upper cover 12, and then remove the locking bolt 23 to remove the connecting block 22 of the limit baffle 20 from the upper cover 12.

[0028] When it is necessary to fix the connecting block 22 of the limiting baffle 20 to the upper cover 12, simply move the through hole of the connecting block 22 directly above the internal threaded hole of the upper cover 12, then pass the end of the first screw away from the first nut through the through hole from above the connecting block 22 and screw it into the internal threaded hole, and make the first nut abut against the connecting block 22, thereby fixing the connecting block 22 of the limiting baffle 20 to the upper cover 12.

[0029] For ease of explanation, the direction from which the center rod 10 is away from the guide plate 16 to the opposite side is defined as the insertion direction, and the direction opposite to the insertion direction is defined as the removal direction.

[0030] Both the lower tray 14 and each guide tray 13 can be equipped with C-shaped weights. For ease of explanation, the lower tray 14 and each guide tray 13 are referred to as weight trays. The method of installing C-shaped weights on each weight tray is the same. Taking the installation of a C-shaped weight on one of the weight trays as an example, during installation, hold the C-shaped weight and move it to the side of the center rod 10 away from the guide plate 16 of the weight tray. Then, turn the opening of the C-shaped weight towards the center rod 10, and then move the C-shaped weight in the insertion direction so that the guide plate 16 of the weight tray passes through the opening of the C-shaped weight. Finally, place the C-shaped weight on the body 15 of the weight tray. When it is necessary to remove the C-shaped weight from the weight tray, simply move the C-shaped weight in the removal direction.

[0031] When it is necessary to install the C-shaped weights onto the orthopedic traction C-shaped weight protection device, first remove the limiting baffle 20 from the upper cover 12, then rotate the limiting baffle 20 downwards so that the end of the limiting baffle 20 away from the lower tray 14 hangs down naturally or rests on the floor; then, install the C-shaped weights required for traction onto the weight tray; after all the C-shaped weights are installed, rotate the limiting baffle 20 upwards and fix the limiting baffle 20 onto the upper cover 12. In this way, the limiting baffle 20 can prevent the C-shaped weights from sliding out of the orthopedic traction C-shaped weight protection device in the removal direction.

[0032] It should be noted that if more than one C-type weight needs to be installed, the C-type weights can be installed on different weight trays.

[0033] In this embodiment, each abutment component is respectively disposed on the strip plate 21 of the limiting baffle 20. Each abutment component includes an abutment bolt 24, and each abutment bolt 24 includes a threaded rod and a nut. In the same abutment bolt 24, the threaded rod is helically connected to the strip plate 21. One end of the threaded rod is the first end, and the other end of the threaded rod is the second end. The first end is located on the side of the strip plate 21 closer to the central rod 10, and the second end is located on the side of the strip plate 21 away from the central rod 10. The nut is fixed to the second end.

[0034] In use, first remove the limiting baffle 20 from the upper cover 12, then rotate the limiting baffle 20 downward so that the end of the limiting baffle 20 away from the lower tray 14 hangs down naturally or rests on the floor; then, install the C-shaped weights required for traction on the weight tray; after all the C-shaped weights are installed, rotate the limiting baffle 20 upward and fix the limiting baffle 20 on the upper cover 12, and then fix each C-shaped weight using the fixing method mentioned below.

[0035] The C-shaped weight is fixed as follows: Taking one of the C-shaped weights as an example, by rotating the abutment bolt 24 corresponding to the section where the C-shaped weight is located, the C-shaped weight is simultaneously abutted against the abutment bolt 24 and the center rod 10, thereby preventing the C-shaped weight from moving in the insertion or removal direction during traction.

[0036] By adopting the above technical solution, a limiting baffle 20 is set on one side of the main body of the device, and each guide plate 16 is set on the side of the central rod 10 away from the limiting baffle 20. The guide plates 16 are located on the same axial plane of the central rod 10, so that the orientation of the C-shaped weights installed on the orthopedic traction C-shaped weight protection device is uniform. The limiting baffle 20 is set in the removal direction of the C-shaped weights. The limiting baffle 20 is provided with a stop component, which can fix the C-shaped weights and prevent them from moving, which is relatively safe. At the same time, when it is necessary to replace the C-shaped weights, the limiting baffle 20 can be removed from the upper cover 12, and the C-shaped weight to be replaced can be taken out in the removal direction. It is not necessary to wait for all the C-shaped weights above the C-shaped weight to be replaced to be removed before taking out the C-shaped weight to be replaced. The replacement of the weights is more convenient.

[0037] It should be noted that the compatibility range of the C-type weight of the orthopedic traction C-type weight protection device provided in this embodiment is as follows: the radius of the C-type weight is smaller than the distance between the center rod 10 and the limiting baffle 20.

[0038] Example 2 like Figure 2 As shown, this embodiment is a further improvement on the basis of embodiment one, as follows: In this embodiment, each abutting component also includes an abutting arc plate 25 and a sleeve 26.

[0039] One side of each abutting arc plate 25 is a concave side, and the other side of each abutting arc plate 25 is a convex side.

[0040] In the same abutment assembly, sleeve 26 is fixed to the convex side of the abutment arc plate 25, and the first end is rotatably connected to sleeve 26. Specifically, the threaded rod of the abutment bolt 24 is coaxially arranged with sleeve 26, and the first end is inserted into sleeve 26. A bearing is provided between the first end and sleeve 26, and the rotatable connection between the first end and sleeve 26 is achieved by providing a bearing between the first end and sleeve 26.

[0041] In use, first remove the limiting baffle 20 from the upper cover 12, then rotate the limiting baffle 20 downward so that the end of the limiting baffle 20 away from the lower tray 14 hangs down naturally or rests on the floor; then, install the C-shaped weight required for traction on the weight tray; then rotate the limiting baffle 20 upward and fix the limiting baffle 20 on the upper cover 12, and then fix each C-shaped weight using the fixing method mentioned below.

[0042] The C-shaped weight is fixed as follows: Taking one of the C-shaped weights as an example, by rotating the abutment bolt 24 corresponding to the section where the C-shaped weight is located, the C-shaped weight is simultaneously abutted against the concave side of the abutment arc plate 25 and the center rod 10. This prevents the C-shaped weight from moving along the insertion or removal direction during traction, and also prevents the abutment bolt 24 from directly contacting the C-shaped weight and causing wear on the C-shaped weight.

[0043] It should be noted that the compatibility range of the C-type weight of the orthopedic traction C-type weight protection device provided in this embodiment is as follows: the reference state of the abutment plate 25 is when the abutment bolt 24 is rotated to the maximum distance between the abutment plate 25 and the center rod 10, and the reference radius is the minimum distance between the abutment plate 25 and the center rod 10 in the reference state. The radius of the C-type weight is smaller than the reference radius.

[0044] Example 3 like Figure 3 As shown, the difference between this embodiment and Embodiment 1 or Embodiment 2 is that the structure of each disk 15 is different.

[0045] In this embodiment, each pan body 15 is provided with a hollow hole 15a, and each hollow hole 15a is located between the central rod 10 and the limiting baffle 20. By providing the hollow hole 15a, it is easy to remove the C-shaped weight from the pan body 15.

[0046] Each pan 15 has an anti-slip assembly at its upper end. In this embodiment, each pan 15 has an anti-slip mounting groove at its upper end; each anti-slip assembly is installed in a corresponding anti-slip mounting groove. Specifically, each anti-slip assembly includes a rubber surface layer and several rubber protruding rings 15b. In the same anti-slip assembly, the rubber surface layer is arranged horizontally, with its lower end fitting against the bottom of the corresponding anti-slip mounting groove. Each rubber protruding ring is integrally connected to the upper end of the rubber surface layer, and the diameters of each rubber protruding ring 15b are different. Each rubber protruding ring 15b is coaxially arranged with the central rod. By setting the anti-slip assembly, the roughness of the upper end of the pan 15 is improved, thereby increasing the friction between the pan 15 and the C-shaped weight, which helps prevent the C-shaped weight from slipping off the pan 15 during the removal or installation of the C-shaped weight.

[0047] The terms "first," "second," "third," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0048] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
