Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and more specifically, relates to an orthopedic threading sleeve. Background Art

[0002] In orthopedic knee posterior cruciate ligament reconstruction surgery, it is often necessary to drill a bone tunnel on the tibia to insert the surgical thread for fixation or other treatment operations. After drilling, the doctor needs to insert a thread grabber from the knee joint cavity to grab the surgical thread for subsequent operations. However, in actual operation, there are many technical difficulties and potential risks. First, there are many nerves and tissues distributed around the exit of the hole, which are crucial for the patient's functional recovery. Therefore, special care should be taken during the operation to avoid damaging them. Secondly, the angle of the hole may be offset, making it difficult to observe the surgical thread coming out of the hole in the direction of the thread grabber. This increases the difficulty of the operation and the risk of accidental injury to the nerve. To solve this problem, doctors usually need to drill another hole from the side of the knee joint to insert an endoscope to observe the position of the surgical thread and the position of the thread grabber. Although this solution can improve the accuracy and safety of the operation to a certain extent, it also brings new problems: an extra wound means that the patient's recovery period may be prolonged, and it also increases the risk of surgery and the incidence of complications.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] In orthopedic surgery, it is sometimes necessary to drill a hole in the tibia to insert surgical wires for fixation or other treatment operations. After drilling the hole, the doctor usually needs to insert a wire grabber from the knee joint cavity to grab the surgical wires for subsequent operations. However, in actual operations, doctors often face many technical difficulties and potential risks.

[0040] First, the hole exit is surrounded by many nerves and tissues, which are vital to the patient's body functions. Therefore, special care must be taken during the operation to avoid damaging these nerves and tissues. Secondly, the problem of deviation of the hole angle also occurs from time to time, which makes it difficult to clearly observe the surgical thread extending from the hole exit in the direction of the thread grabber. This not only increases the difficulty of the operation, but also greatly increases the risk of accidental injury to the nerves.

[0041] In order to solve the above problems, doctors usually need to take additional measures, such as making another hole from the side of the knee joint to insert an endoscope to observe the position of the surgical thread and the position of the thread grabber. However, although this method can improve the accuracy of the operation to a certain extent, it brings additional trauma to the patient. An extra wound means that the patient's recovery period may be prolonged, and it may also increase the risk of surgery and the incidence of complications.

[0042] In order to reduce the trauma of patients and lower the risk of surgery, the present application proposes an orthopedic threading sleeve. Figures 1 to 3 As shown, the present application provides an orthopedic threading sleeve including a fixed tube 1, a movable tube 2 and a control member 3.

[0043] One end of the fixed tube 1 has a threading inlet 11 for inserting the surgical thread; the other end of the fixed tube 1 has a movable joint, so that the entire threading sleeve can be flexibly adjusted in angle when in use. The doctor can hold the fixed tube 1 stably during operation.

[0044] One end of the movable tube 2 has a threading outlet 21 through which the surgical thread is passed; the other end of the movable tube 2 is connected to the movable joint, and the movable tube 2 can be flexibly bent around the movable joint to adjust the position of the threading outlet 21 .

[0045] The control member 3 is sequentially passed through the inner sides of the fixed tube 1 and the movable tube 2, one end of the control member 3 is connected to the movable tube 2, and the other end of the control member 3 extends out of the fixed tube 1 from the threading inlet 11. The control member 3 can be movably connected to the inner sides of the fixed tube 1 and the movable tube 2; by pulling or tugging the control member 3, the movable tube 2 can be conveniently controlled to bend to one side, thereby realizing precise positioning of the surgical line.

[0046] During the operation, the doctor can first insert the orthopedic threading sleeve along the pre-opened hole on the tibia in the order of the movable tube 2 in front and the fixed tube 1 in the back. When the movable tube 2 passes through the tibial hole, the doctor only needs to pull the control member 3 with a certain force to bend the movable tube 2 to one side, so that the threading outlet 21 is facing the direction of the thread grabber. In this way, the doctor can not only clearly observe the position of the surgical thread, but also conveniently use the thread grabber to clamp the surgical thread for subsequent operations.

[0047] Through the orthopedic threading sleeve of the present application, doctors can complete the threading operation in orthopedic surgery more accurately and efficiently, while reducing the patient's trauma and surgical risks and promoting the patient's rapid recovery.

[0048] Figures 1 to 3 As shown, in one embodiment of the present application, the movable joint is a spherical hinge joint 12, which has good flexibility and stability, and can ensure that the movable tube 2 can be smoothly bent or rotated thereon. The movable tube 2 can be tightly hinged on the spherical hinge joint 12, so as to achieve multi-angle and multi-directional adjustment to meet different surgical needs. During the operation, the doctor can flexibly adjust the angle and position of the movable tube 2 through the control member 3 according to actual needs to ensure that the surgical line can be accurately passed through for easy clamping by the thread grabber.

[0049] Figures 1 to 3 As shown, in one embodiment of the present application, the spherical articulated joint 12 includes a ball head 121, and one end of the movable tube 2 is a ball head seat 22. The shape of the ball head seat 22 matches the ball head 121, and can be stably and flexibly sleeved on the ball head 121. The ball head seat 22 can be movably sleeved on the ball head 121, and the ball head seat 22 can be arbitrarily bent or rotated around the spherical surface of the ball head 121, so as to meet the needs of different surgical scenarios.

[0050] Figure 4 and Figure 5As shown, in one embodiment of the present application, the movable joint is an elastic bellows 13, and the movable tube 2 is connected to the elastic bellows 13. In actual operation, when the doctor pulls the control member 3 during the operation, the movable tube 2 moves closer to the fixed tube 1, and the elastic bellows 13 is subjected to axial compression. Since the force on the control member 3 only acts on one side of the movable tube 2, one side of the elastic bellows 13 is subjected to compression force, and the other side of the elastic bellows 13 is subjected to extension force, and the elastic bellows 13 bends toward the compression side, thereby adjusting the position and orientation of the threading outlet 21 to make it closer to the insertion direction of the thread grabber. In this way, the doctor can more conveniently observe and locate the position of the surgical thread, and then use the thread grabber to accurately clamp the surgical thread for subsequent surgical operations. When the traction of the control member 3 is removed, the elastic bellows 13 returns to its original state by virtue of its own elasticity. Compared with the spherical articulated joint 12, the outer surface of the elastic bellows 13 has no seams, and will not clamp the patient's tissue when bending to cause secondary damage, which is less harmful to the patient.

[0051] Figure 4 and Figure 5 As shown, in one embodiment of the present application, the elastic bellows 13 includes a plurality of elastic bends arranged in sequence, and the elastic bends are compressed and deformed when subjected to external force, and can return to their original state after the external force is removed. When one side of the elastic bend is compressed in the axial direction, the other side of the elastic bend is expanded in the axial direction. The compression amount and expansion amount of each elastic bend are gradually added to form the overall compression amount and expansion amount of the elastic bellows 13.

[0052] Figure 4 and Figure 5 As shown, in one embodiment of the present application, the movable tube 2 and the elastic bellows 13 are an integrated structure. The integrated structure not only significantly enhances the connection strength and stability between the movable tube 2 and the elastic bellows 13, but also greatly improves the durability of the overall structure. Since the two are integrally formed, no seams or gaps are generated on the surface, thereby effectively avoiding performance degradation or failure caused by loose or worn seams.

[0053] Figure 2 and Figure 4As shown, in one embodiment of the present application, a fixing bolt 23 is provided on the inner wall of the movable tube 2, and the control member 3 is connected to the fixing bolt 23 and is close to the inner wall of the movable tube 2. When the control member 3 is pulled, the force on the fixing bolt 23 generates a torque on the spherical hinge joint 12, so that the movable tube 2 is bent around one side of the spherical hinge joint 12; or, the force on the fixing bolt 23 is on the elastic bellows 13, one side of the elastic bellows 13 is subjected to compressive stress, and the other side of the elastic bellows 13 is subjected to tensile stress, and the elastic bellows 13 is bent toward the side subjected to compressive stress. Therefore, when the control member 3 is pulled, the movable tube 2 can bend around one side of the movable joint, rather than being equivalent to the fixed tube 1 being brought together as a whole.

[0054] In one embodiment of the present application, there are multiple control members 3, and each control member 3 is arranged at intervals from each other along the circumference of the movable tube 2. This layout not only makes the force more uniform, but also achieves more precise control.

[0055] Specifically, by evenly distributing multiple control components 3 along the circumference of the movable tube 2, when the doctor operates during the operation, each control component 3 can share part of the force, thereby avoiding deformation or damage caused by excessive force on a single point. This design makes the entire threading sleeve more stable when subjected to force, and is not prone to deviation or shaking. At the same time, the precise arrangement of multiple control components 3 also enables the doctor to more accurately control the bending angle and direction of the movable tube 2. By adjusting the force conditions of different control components 3, the doctor can flexibly change the bending state of the movable tube 2 to adapt to different surgical needs. This flexibility not only improves the efficiency of the operation, but also reduces the risks caused by improper operation.

[0056] In one embodiment of the present application, the control member 3 is a traction rope, one end of which is connected to the fixing bolt 23 to ensure the stability and reliability of the connection. The other end of the control member 3 extends out of the fixing tube 1 from the threading inlet 11, providing a convenient means of control for the doctor. The traction rope can easily adapt to the bending of the movable tube 2 in various situations, ensuring that the movable tube 2 can be smoothly pulled during the operation to achieve precise threading operation.

[0057] In one embodiment of the present application, the length of the movable tube 2 is in the range of 0.8 cm to 1.0 cm. Within this length range, the movable tube 2 can be flexibly moved and bent in the knee joint during surgery to meet the needs of different surgical scenarios, while avoiding the inconvenience of operation or difficulty in threading caused by too long or too short a length.

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
