Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a medical sliding locking ring structure. Background Technology

[0002] Medical anchors are screws implanted inside the bones of patients during orthopedic surgery. They are basically the same as common screws in structure, mainly consisting of a cutting edge at the front end, a central column, and a tail. Usually, there is an opening at the tail or front end of the anchor to allow surgical sutures to pass through. They are used in conjunction with sutures during surgery to fix, reduce tension, pull, and suture avulsion fractures, joint capsules, tendons, ligaments, and muscles.

[0003] In actual surgery, multiple anchors are inserted into the surgical site. During the procedure, the sutures on one anchor need to be passed through the perforation on another anchor to ensure the smooth progress of the subsequent surgery. However, in practice, because the perforations on the surface of the anchors are small, the sutures cannot be passed through another anchor after one anchor is inserted into the surgical area. The only way to fix it is to tie the sutures on the anchors together, which is extremely inconvenient and carries the risk of too many suture knots in the surgical area and suture slippage, leading to fixation failure. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A medical sliding locking ring structure, characterized in that it comprises:

[0006] The locking loop allows surgical sutures to pass through its interior, and the entire locking loop can pass through the suture hole at the tail of the anchor.

[0007] The traction mechanism includes a traction member that can pass through a hole at the tail of the anchor and drive the locking ring to move, and a movable connector that connects the traction member and the locking ring.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the number of the moving parts is at least two.

[0010] Furthermore, the locking ring has an overall ring structure, and all the moving parts are evenly distributed at two points opposite each other on the surface of the locking ring.

[0011] Furthermore, the pulling member is generally linear in shape, and the movable connecting member is generally annular in shape, with the movable connecting member sleeved on the surface of the locking ring.

[0012] Furthermore, one end of the movable connector is connected to one end of one of the pulling members among all the movable members, and the interior of this movable connector is passed through by another pulling member.

[0013] Furthermore, the locking ring is composed of all movable connecting parts and pulling parts. The end of the pulling part away from the locking ring extends to the outside of the locking ring. When all the pulling parts are pulled away from the end of the locking ring, the inner diameter of the locking ring can be reduced.

[0014] Furthermore, the traction member has an overall ring-shaped structure.

[0015] Furthermore, each of the aforementioned tension members has a movable connector at both ends.

[0016] Beneficial effects

[0017] Compared with existing technologies, this invention, through the cooperation of a locking ring and a traction mechanism, allows the locking ring and traction mechanism to be passed through the holes in the anchors during surgery. When it is necessary to pass the sutures on other anchors through this anchor for surgery, the sutures connected to the other anchors are then passed through the locking ring. The traction mechanism quickly moves the sutures through the holes in the anchors, allowing for rapid adjustment of the suture positions on the anchors according to the surgical procedure. This effectively saves surgical time, reduces the risk of suture knots and loosening in the surgical area, and improves surgical efficiency. At the same time, the locking ring, in cooperation with the traction member and the movable connector, forms a ring structure that gradually contracts under the action of the traction member, ensuring that the surgical sutures in the locking ring are stably connected to the locking ring and preventing them from falling off during operation.

[0029] Please see Figure 1-4 The present invention provides a medical sliding locking ring structure, comprising a locking ring 1 that allows surgical sutures to pass through, a traction movable part 2 that can move the locking ring 1, and a medical anchor with a threading hole on its surface.

[0030] The locking loop 1 is made of common medical suture material and can pass through the suture hole at the tail of the bone nail. The traction movable part 2 includes a traction member 21 that can pass through the hole on the bone nail and drive the locking loop 1, and a movable connector 22 that connects the traction member 21 and the locking loop. Both the movable connector 22 and the traction member 21 can be common medical suture materials. The number of the traction movable parts 2 is at least two, preferably two. The locking loop 1 has a ring structure and all the traction movable parts 2 are evenly distributed at two points opposite each other on the surface of the locking loop 1.

[0031] As shown in the figure, when it is necessary to pass the suture on one anchor to another, the pulling member 21 and the locking loop 1 can be passed through the hole on the other anchor first, and then the suture can be passed into the locking loop 1. At this time, the suture is located inside the locking loop 1. The operator only needs to pull the pulling member 21 to realize the rapid insertion and exit of the suture on the anchor. The suture can be quickly passed through the hole according to the needs of the operation, avoiding the time wasted by manually threading the suture during the operation.

[0032] To provide a detailed explanation of the above technical solutions, the following embodiments are disclosed.

[0033] Example 1:

[0034] Please see Figure 1 The traction member 21 has a linear structure, and the movable connector 22 has a ring structure. The movable connector 22 is sleeved on the surface of the locking ring 1. At this time, the traction member 21 also has a single-line structure. During use, since the traction member 21 has a single-line structure, it is easier to distinguish the positions of the two traction lines during operation. In the case of urgent surgery, it can effectively reduce the operation time.

[0035] Example 2:

[0036] Unlike Example 1, in Example 1, the locking loop 1 is an integral, non-retractable ring structure, which makes it easy for the suture to fall out of the locking loop 1 during operation. Please refer to [link / reference needed]. Figure 1 One end of the movable connector 22 is connected to one end of a tension member 21 among all the movable members, and the interior of the movable connector 22 is passed through by another tension member 21.

[0037] At this time, the locking ring 1 is composed of all the movable connectors 22 and the traction member 21. The end of the traction member 21 away from the locking ring 1 extends to the outside of the locking ring. When the end of all the traction members 21 away from the locking ring 1 is pulled, the inner diameter of the locking ring 1 can be reduced. The movable connectors 22 can also be a ring-shaped linear structure. Through the locking ring 1 that can be contracted after being pulled, the surgical suture can be controlled.

[0038] Example 3:

[0039] Unlike Embodiment 2, the traction member 21 has an overall ring-shaped structure. The ring-shaped traction member 21 can be pulled more easily during the operation, avoiding slippage. The movable connector 22 can be a rigid strip structure or a soft medical wire. Each traction member 21 has a movable connector 22 at both ends. With the small movable connector 22, the user can quickly pass the movable connector 22 through the hole on the anchor, saving operation time.

[0040] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
