Description

Technical Field

[0001] The present invention relates to the technical field of trocars, in particular to a disposable rotator cuff trocar and a method for using the same. Background Art

[0002] In today's medical field, minimally invasive surgery has become the preferred method for treating many diseases due to its many advantages such as less trauma, faster recovery, and fewer complications. It occupies an increasingly important position in orthopedic surgery. As an indispensable key instrument in minimally invasive surgery, the core function of the trocar is to build a safe and stable body cavity channel, creating the necessary conditions for subsequent surgical operations.

[0003] With the continuous development of minimally invasive technology, the application of traditional linear puncture devices in shoulder joint surgery has gradually exposed many limitations. Due to the unique structure of the shoulder joint, the humeral head is round and the surrounding tissues are intricately distributed, which greatly limits the surgical field of view. Under such anatomical structure and field of view conditions, the suturing instruments guided by traditional linear puncture devices are often difficult to approach the suture site from the appropriate angle during operation. Especially when suturing the connection between the rotator cuff tissue and the humeral head, the linear puncture device is often unable to accurately penetrate the target tissue due to angle problems. This will not only lead to inaccurate suturing and affect the repair effect, but may also cause damage to important structures such as peripheral nerves and blood vessels, bringing additional pain and risks to patients. Summary of the Invention

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] The embodiment of the present invention discloses a disposable rotator cuff puncture device, according to the attached Figure 1-4 Shown, including:

[0045] The handle assembly serves as the operator's grip, providing a fulcrum for the operator to easily control the trocar.

[0046] The outer tube 4 of the suture gun is movably connected to the handle assembly. The outer tube 4 of the suture gun provides an installation basis for the inner rod 5 of the suture gun, the outer long tube 42, etc., and participates in the operation movement of the entire puncture device. The outer tube 4 of the suture gun is fixedly connected to the outer long tube 42, and the outer long tube 42 is provided with a curved thorn head 43. The curved thorn head 43 is used to perform puncture and other actions during the operation to assist in completing related medical operations:

[0047] The inner rod 5 of the suture gun is arranged in the outer tube 4 of the suture gun and can move relative to the outer tube 4 of the suture gun to drive the end assembly 53 to move, thereby realizing operations such as hooking the suture. The inner rod 5 of the suture gun is movably connected to the handle assembly. The inner rod 5 of the suture gun is fixedly connected to the inner long tube 52. The function of the inner long tube 52 is to transmit the movement of the inner rod 5 of the suture gun to the end assembly 53:

[0048] The end assembly 53 is provided on the inner long tube 52 and is used to hook the suture. The end assembly 53 is a key action component for realizing the suturing function. Through the design of different shapes, it can meet the suture hooking requirements in various complex situations and ensure the smooth progress of the suturing operation.

[0049] According to the attached Figure 9-11As shown, further, the handle assembly includes:

[0050] Handle 1 is the main part for the operator to hold. The surface of the handle has been specially anti-slip treated to increase friction, ensuring that the operator can hold it firmly even if there is blood on the hand during the operation, avoiding operational errors caused by slipping hands;

[0051] The push rod 2 is movably connected to the handle 1. The push rod 2 is used to transmit the pushing force of the operator. By its own movement, it drives other related parts to move, thus realizing the operation function of the trocar.

[0052] The inner sleeve 3 is movably connected to the push rod 2, and the inner sleeve 3 plays the role of transmitting movement and connecting and fixing.

[0053] According to the attached Figure 1-3 As shown, further, a second clamping block 41 is fixedly connected to the outer tube 4 of the suture gun, and a second bayonet 31 is provided on the inner sleeve 3, and the outer tube 4 of the suture gun is clamped with the inner sleeve 3. This design makes the connection between the outer tube 4 of the suture gun and the inner sleeve 3 stable and reliable, and can move synchronously during operation, ensuring the overall coordination of the puncture device.

[0054] According to the attached Figure 4 As shown, it is particularly disclosed that a baffle 51 is fixedly connected to the inner rod 5 of the suture gun, which can effectively limit the movement distance of the inner rod 5 of the suture gun, prevent it from excessive movement and damage to other components, and at the same time accurately transmit the force applied by the operator to the end assembly 53, ensuring the smooth progress of the suture hooking operation.

[0055] According to the attached Figure 10 As shown, it is particularly disclosed that a boss 21 is provided in the push rod 2, which plays a role of limiting. It can effectively limit the movement range of the inner rod 5 of the suture gun to prevent damage caused by excessive movement of the components, and can ensure that the inner rod 5 of the suture gun can move flexibly within the normal working range, thereby realizing the precise operation function of the puncture device.

[0056] According to the attached Figure 9-11 As shown, it should be emphasized that a first bayonet 11 is provided on the handle 1, and a first clamping block 32 is fixedly connected to the inner sleeve 3. The handle 1 and the inner sleeve 3 are clamped together to make the connection stable and easy to disassemble.

[0057] According to the attached Figure 5-8 As shown, it should be particularly emphasized that the end assembly 53 is a first hook head 531. The shape of the first hook head 531 is an oblique groove, which can better grasp and guide the suture during the suturing process, making the suture smoother when entering the hook head, reducing the possibility of suture slippage, thereby improving the efficiency and accuracy of suturing;

[0058] The end assembly 53 is a second hook head 532. The second hook head 532 has a double-bevel groove shape. The second hook head 532 increases the contact area and angle for hooking the suture. When facing complex suturing scenarios, the double-bevel groove design can grab the suture from different directions, making it easier to hook the suture, improving operational flexibility and adapting to a wider range of surgical needs.

[0059] The end assembly 53 is a third hook head 533. The third hook head 533 is shaped like a convex character, which can better fit into the suture. The convex character structure design makes the third hook head 533 more closely contact with the suture, enhances the firmness of the hook, and effectively prevents the suture from falling off during the suturing process. It is particularly suitable for operations that require high suture firmness, such as rotator cuff tissue repair.

[0060] The end assembly 53 is a fourth hook head 534, and the shape of the fourth hook head 534 is a claw shape, which can clamp the suture from multiple directions. The claw-shaped design provides a stronger gripping force, which can more firmly grasp the suture during the suturing process to ensure the smooth progress of the suturing. For some sutures with a smoother or thinner texture, the claw-shaped hook head can play a better role and improve the quality and safety of the operation.

[0061] According to the attached Figure 2-4 As shown, further, a spring 6 is provided between the outer tube 4 of the suture gun and the inner rod 5 of the suture gun, and the spring 6 can play a reset role. When the operator completes a suture hooking operation, the elastic force of the spring 6 can automatically return the inner rod 5 of the suture gun to the initial position, and prepare for the next operation, thereby improving the efficiency and consistency of the operation. The bending angle of the curved thorn head 43 is set between 30° and 60°. This bending angle design helps the curved thorn head 43 to achieve precise puncture within a specific rotator cuff operating space, and will not cause puncture difficulties or inability to reach the target site due to a small angle, nor will it damage the surrounding tissue due to an excessively large angle. Tiny raised textures are provided on the inner side of the end assembly 53. These raised textures increase the friction between the end assembly 53 and the suture, further improving the stability and firmness of the suture hooking. During the suturing process, even if the suture is pulled by a certain external force, it is not easy for the suture to slip off the end assembly 53, thereby ensuring the smooth progress of the suturing operation.

[0062] The method of using the disposable rotator cuff puncture device includes the following steps:

[0063] Step S1: The operator selects a suitable type from the end assembly 53, pushes the push rod 2, extends the end assembly 53, and clamps the required type of suture into the outer tube 42;

[0064] Step S2: Hold the puncture handle 1, aim the curved puncture head 43 at the target puncture site, and use the outer long tube 42 to puncture so that the curved puncture head 43 penetrates the tissue to the predetermined position;

[0065] Step S3: pushing the push rod 2 to extend the end assembly 53 and release the suture into the tissue;

[0066] Step S4: At the corresponding position on the opposite side, the puncture suture needle is removed, and the outer tube 42 is passed through the tissue again to clamp the previously released suture thread, and the puncture suture needle is removed and the suture thread is pulled out at the same time:

[0067] Step S5: Tie the sutures with appropriate knotting techniques to complete tissue closure or anastomosis.

[0068] When using the disposable rotator cuff trocar, the operator first selects a suitable model from a variety of end assembly 53 shapes according to actual needs. The end assembly 53 includes a first beveled groove-shaped hook head 531, a second double-beveled groove-shaped hook head 532, a third convex-shaped hook head 533, and a fourth claw-shaped hook head 534. The different shapes of the end assembly 53 can adapt to different operating scenarios and better hook the suture.

[0069] After selecting the end assembly 53, the operator pushes the push rod 2 in the handle assembly. The push rod 2 is movably connected to the handle 1. Its movement drives the inner sleeve 3 and its associated components to move. Since the suture gun inner rod 5 is movably connected to the handle assembly and is connected to the inner sleeve 3, the push of the push rod 2 causes the suture gun inner rod 5 to move relative to the suture gun outer tube 4. The suture gun inner rod 5 is fixedly connected to the inner long tube 52. The inner long tube 52 transmits the movement to the end assembly 53, so that the end assembly 53 is extended to clamp the required type of suture thread into the outer long tube 42.

[0070] Next, the operator holds the handle 1 of the puncture instrument and aligns the curved puncture head 43 on the outer tube 4 of the suture gun with the target puncture site. The bending angle of the curved puncture head 43 is set between 30° and 60°. This specific angle facilitates precise operation within the rotator cuff operation space. Through the puncture action of the outer tube 42, the curved puncture head 43 penetrates the tissue to reach the predetermined position.

[0071] After reaching the predetermined position, the push rod 2 is pushed again to extend the end assembly 53 and release the previously clamped suture into the tissue;

[0072] At the corresponding position on the opposite side, similar operations are repeated, the outer tube 42 is passed through the tissue again, the end assembly 53 is used to clamp the previously released suture, and the puncture suture needle is removed while the suture is pulled out;

[0073] Finally, use appropriate knotting techniques to tie and suture the pulled suture to complete the closure or anastomosis of the tissue. During this process, the spring 6 set between the suture gun outer tube 4 and the suture gun inner rod 5 can play a reset role, ensuring that the components can return to their initial state after operation, which is convenient for subsequent operations or removal of the instrument. The tiny raised texture set on the inner side of the end assembly 53 helps to enhance the hooking and fixing effect of the suture, ensuring the smooth progress of the suturing process.
