Description

Technical Field

[0001] This utility model relates to the field of strap buckle technology, specifically a fracture strap assembly. Background Technology

[0002] In modern orthopedic medicine, circumferential ligation bands are frequently used for internal fixation of oblique split fractures in order to achieve good medical results.

[0003] However, currently used locking buckles are all one-piece molded, and the space for inserting the binding straps is fixed. This makes operation difficult when wrapping the binding straps, reducing surgical efficiency. Furthermore, after the straps are tightened, the shape of the bone can cause a cone-like structure on the straps, leading to axial displacement and affecting the fixation effect. Therefore, this fracture binding strap component was designed to improve surgical efficiency while enhancing the positioning effect of the binding straps. Utility Model Content

[0004] The purpose of this invention is to provide a fracture bandage assembly. By attaching a movable buckle to the locking body, the movement of the movable buckle increases the threading space of the bandage, making it easier to wrap. At the same time, the movement of the movable buckle can reduce the space on one side of the bandage, clamping the bandage and fixing one end of the bandage, making it easier to contract the bandage and improving the efficiency of internal fixation surgery for fractures. Meanwhile, the contraction of the other end of the bandage will further move the movable buckle, pressing the bandage between the movable buckle and the locking body, improving the positioning effect on the bone.

[0005] This utility model provides the following technical solution: a fracture bandage assembly, including a locking body and a movable buckle. The movable buckle is sleeved on the locking body. A bandage is wrapped around one end of the locking body, and the other end of the bandage is wrapped around the movable buckle. A slip knot is formed on the movable buckle and the locking body. The movable buckle is close to the other end of the locking body, pressing the bandage between the movable buckle and the locking body. The bandage at the other end of the locking body contracts, wrapping the bandage around the fracture site and contracting and pressing it tightly.

[0006] In order to limit the movement of the movable buckle and prevent it from slipping off the buckle body, blocks are formed on both sides of one end of the buckle body. The blocks are located on one side of the movable buckle and block it.

[0007] The latch body has a rectangular frame, and the movable buckle has a rectangular hole inside. The movable buckle is fitted onto the side of the latch body through the rectangular hole.

[0008] To enhance the positioning of the strap, a buckle body is inserted into the rectangular hole, which can also be used to insert the strap.

[0009] To prevent the strap from slipping on the buckle and the stop, a second toothed surface is formed on one side of the buckle, and a first toothed surface is formed on the other side of the stop. The first and second toothed surfaces are located on opposite sides of the strap insertion point. The movable buckle and the buckle body are made of PEEK, PEKK, PE, PET, PTFE, titanium alloy or stainless steel.

[0010] An antibacterial coating is uniformly applied to the surface of the strap.

[0011] The strap is woven from multiple warp and weft threads. Both the warp and weft threads are single strands. Each single strand is formed by twisting multiple fibers. The diameter of a single fiber is 6-30 μm, and the single strand is 10-2000 tex.

[0012] One end of the strap is connected to a traction element, which is a curved needle, hook, or plate. The traction element pulls the strap, making it easier to wrap the strap around the bone fracture.

[0013] The straps are blue, black, yellow, or green.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by attaching a movable buckle to the locking body, the size of the space on both sides of the movable buckle can be adjusted by the movement of the movable buckle, which facilitates the wrapping of the strap and improves the wrapping efficiency of the strap. At the same time, the movement of the movable buckle can also clamp the strap between the movable buckle and the locking body. Furthermore, when tightening the strap, the movable buckle can be moved further to press the strap, thereby improving the strap's ability to position the bone. Attached Figure Description

[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. Example 1

[0017] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a fracture bandage assembly, including a locking body 1 and a movable buckle 2. The movable buckle 2 is sleeved on the locking body 1. A bandage 3 is wrapped around one end of the locking body 1, and the other end of the bandage 3 is wrapped around the movable buckle 2. The bandage 3 has a slip knot formed on the movable buckle 2 and the locking body 1. When the bandage 3 is wrapped, the movement of the movable buckle 2 increases the distance between the two ends of the movable buckle 2 and the locking body 1, making it easier for the bandage 3 to be inserted into the locking body 1 and the movable buckle 2, improving the insertion efficiency of the bandage 3 and further improving the surgical efficiency. When tightening, the movable buckle 2 moves closer to the other end of the locking body 1, reducing the distance between the movable buckle 2 and the locking body 1, pressing the bandage 3 between the movable buckle 2 and the locking body 1. The contraction of the bandage 3 at the other end of the locking body 1 will drive the movable buckle 2 to move, further tightening the bandage 3. The bandage 3 is pressed between the movable buckle 2 and the locking body 1, wrapped around the fracture site and tightened to fix the fracture. In summary, by moving the movable buckle 2 on the locking body 1, the distance between the movable buckle 2 and the locking body 1 can be adjusted. When the distance is larger, it is easier to insert the bandage 3 onto the movable buckle 2, improving the wrapping efficiency of the bandage 3. When the distance is smaller, one end of the bandage 3 can be clamped between the movable buckle 2 and the locking body 1, and the other end of the bandage 3 can be contracted to adjust the size of the slip knot of the bandage 3, binding the bandage 3 to the fracture site to fix the bone. At the same time, pulling on the end of the bandage 3 wrapped around the movable buckle 2 can contract the bandage 3 at that end, further reducing the size of the slip knot of the bandage 3, fixing the bandage 3 to the bone, improving the positioning effect of the bone, and reducing the possibility of the bandage 3 shifting.

[0018] The locking body 1 has two blocks 11 formed on both sides of one end. The blocks 11 are located on one side of the movable buckle 2 and block the movable buckle 2 to prevent the movable buckle 2 from slipping off the locking body 1.

[0019] The buckle body 1 has a rectangular frame, and the movable buckle 2 has a rectangular hole 21 inside. The size of the rectangular hole 21 is larger than the side size of the buckle body 1. The movable buckle 2 is sleeved on the side of the buckle body 1 through the rectangular hole 21. By moving the movable buckle 2, the insertion space of the strap 3 inside the buckle body 1 is adjusted, thereby improving the wrapping efficiency of the strap 3.

[0020] The locking body 1 is inserted into the rectangular hole 21, and the strap 3 can also be inserted into the rectangular hole 21, which increases the locking force of the strap 3 on the movable buckle 2, further enhances the positioning ability of the bone, and reduces the deviation of the strap 3.

[0021] The movable buckle 2 and the locking body 1 are made of PEEK, PEKK, PE, PET, PTFE, titanium alloy or stainless steel.

[0022] An antibacterial coating is evenly applied to the surface of the strap 3 to ensure its cleanliness and reduce the risk of the instrument being infected by bacteria.

[0023] The binding strap 3 is woven from multiple warp and weft threads. Both the warp and weft threads are single strands. Each single strand is formed by twisting multiple fibers. The diameter of a single fiber is 6-30μm, and the single strand is 10-2000tex.

[0024] like Figure 5 and 6 As shown, a traction element 4 is connected to one end of the strap 3. The traction element 4 is a hook, a bent plate, or a bent needle. A lifting ring is formed on the end face of the bent needle, hook, or bent plate. The end of the strap 3 passes through the lifting ring of the bent needle or hook and is pressed against the side of the strap 3. A pressure tube is formed on one end of the bent needle or hook. The end of the strap extends into the pressure tube. The strap is fixed to the end of the bent needle or hook by the deformation of the pressure tube.

[0025] The strap 3 is available in blue, black, yellow, or green. Example 2

[0026] like Figure 3 and 4 As shown, a second toothed surface 22 is formed on one side of the movable buckle 2, and a first toothed surface 111 is formed on the other side of the stop block 11. The first toothed surface 111 and the second toothed surface 22 are located on both sides of the strap insertion position, which increases the friction on the strap 3 and prevents the strap 3 from sliding and affecting the locking of the strap 3.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
