Abstract
Description
Technical Field
[0001] This utility model relates to a medical device, and more specifically, to a surgical device for urinary incontinence suspension surgery. Background Technology
[0002] Currently, the most common surgical treatment for urinary incontinence is mid-urethral suspension correction, which is one of the standard surgical treatments for female stress urinary incontinence. It uses a guide handle to implant a thin mesh sling under the urethra, in the tissue gap between the lower urethra and the anterior vaginal wall. This can correct and reduce urethral swaying. The implanted mesh sling can also play an elastic suspension and support role through a certain degree of adhesion and tissue reaction with the tissue.
[0003] The surgical instruments used in urinary incontinence sling surgery mainly consist of a mesh sling and a guide handle. Currently, the most common mesh sling is fixed with sutures. The guide handle has a hook groove at the puncture head, which is used to hook the sutures at both ends of the mesh sling for fixation. This traditional suture method has certain drawbacks. For example, the hook groove on the puncture head can easily become entangled with the tissue during puncture, increasing puncture trauma, and there is also a risk of suture dislodgement during the hooking operation. To address the problems associated with using sutures to fix the mesh sling, a cannulated mesh sling has emerged on the market. This type has pointed cannulas at both ends of the mesh sling. During use, the guide rod of the guide handle is inserted into the cannulas for operation, solving the problem of the hook groove on the puncture head becoming entangled with the tissue. However, because there is no fixed connection between the guide rod and the cannulas, and the inside of the cannulas is smooth, the instrument can easily detach from the cannulas during the procedure, leading to surgical failure. Currently, there are also improved cannula structures, which add a ring-shaped anti-reverse protrusion inside the cannula and a ring-shaped groove at the corresponding position of the guide rod end of the guide handle, reducing the risk of the instrument detaching from the cannula. However, due to the long length of the cannula, the anti-reverse protrusion is generally located at the pointed end of the cannula, requiring the guide rod of the guide handle to be inserted into the cannula deeply for engagement. On the one hand, there is a possibility that the operation may not be able to reach the correct position, resulting in incomplete engagement and the risk of detachment. On the other hand, because the fit between a single protrusion and groove is not very firm, there is still a significant risk of detachment under stress. Summary of the Invention
[0004] 1. Technical problem to be solved by the utility model
[0005] The purpose of this invention is to overcome the aforementioned shortcomings of existing cannulated mesh slings and provide a surgical instrument for urinary incontinence suspension surgery. Using the technical solution of this invention, the first anti-retraction structure on the puncture cannula and the second anti-retraction structure on the guide handle are designed as a spiral locking structure with mutual concave and convex fits, or at least two turns of annular locking structure with mutual concave and convex fits. The spiral locking structure or multi-turn annular locking structure increases the firmness of the connection between the guide handle and the puncture cannula, effectively preventing accidental detachment due to force during operation. Furthermore, the increased number of connection points reduces the probability of detachment due to improper installation during assembly, greatly improving the success rate and safety of the surgery.

[0037] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.
[0038] [Example 1]
[0039] Combination Figure 1 As shown, a surgical instrument for urinary incontinence suspension surgery according to this embodiment includes a mesh sling 1 and a guide handle 2. The mesh sling 1 includes a mesh 1-1 and a puncture cannula 1-2 connected to both ends of the mesh 1-1. The puncture cannula 1-2 is a flexible tube with a pointed tip 1-2-1. The pointed tip 1-2-1 is a solid structure to prevent deformation during production, transportation or puncture. The sharp end of the pointed tip 1-2-1 is rounded to make the pointed tip 1-2-1 sharp but not sharp, which can prevent it from puncturing gloves or fingers during surgery. A side perforation hole 1-2-2 is provided on the side wall of the end of the puncture cannula 1-2 away from the pointed tip 1-2-1, and a first anti-retraction structure 1-2-3 is provided on the inner side wall of the end of the puncture cannula 1-2 near the pointed tip 1-2-1. The guide handle 2 includes an operating handle 2-1 and a guide rod 2-2 fixed on the operating handle 2-1. The free end of the guide rod 2-2 has a second anti-retraction structure 2-2-1. The free end of the guide rod 2-2 can be inserted into the puncture cannula 1-2 through the side perforation hole 1-2-2, and cause the first anti-retraction structure 1-2-3 to combine with the second anti-retraction structure 2-2-1, thereby using the guide handle 2 to perform a puncture operation on the puncture cannula 1-2. In this embodiment, the first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 are mutually interlocking spiral locking structures. The design of the first anti-retraction structure 1-2-3 on the puncture cannula 1-2 and the second anti-retraction structure 2-2-1 on the guide handle 2 as mutually interlocking spiral locking structures increases the firmness of the connection between the guide handle 2 and the puncture cannula 1-2, effectively preventing accidental disengagement due to force during operation. Furthermore, the increased number of connection points reduces the probability of disengagement due to improper installation during assembly, greatly improving the success rate and safety of the surgery.
[0040] like Figures 2 to 5As shown, in this embodiment, the first anti-retraction structure 1-2-3 is a spiral boss on the inner wall of the puncture cannula 1-2, and the second anti-retraction structure 2-2-1 is a spiral groove on the outer wall of the guide rod 2-2. The spiral boss and spiral groove can be designed with multiple turns to increase the connection length. In this embodiment, the first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 can be forcibly squeezed together or screwed together in the spiral direction. They can be connected by forced squeezing or screwing together according to the shape of the guide rod 2-2, making the connection operation convenient and highly applicable. In this embodiment, the spiral boss is a continuous spiral boss. The height of the spiral boss can be designed to be within 0.1 to 1 mm, and the depth of the spiral groove matches it. The mating gap between the spiral boss and the spiral groove is controlled within 0.05 to 0.2 mm to increase the gripping force of the cannula on the guide rod 2-2. Additionally, as... Figure 5 As shown, after the first anti-reverse structure 1-2-3 and the second anti-reverse structure 2-2-1 are installed in place, the end face of the guide rod 2-2 should ideally abut against the rear side of the pointed head 1-2-1 to avoid forming a cavity between them and reducing the strength of the head end. Figure 4 As shown, the end of the guide rod 2-2 also has a chamfer 2-2-2 to prevent the guide rod 2-2 from scratching the inner surface of the cannula and generating debris during the process of inserting the puncture cannula 1-2.
[0041] Reference Figure 9As shown, the surgical instrument for urinary incontinence suspension in this embodiment has a plug 1-2-4 at the end of the puncture cannula 1-2 away from the tip 1-2-1. The plug 1-2-4 has a plug hole. The two ends of the mesh 1-1 are inserted into the plug holes of the corresponding puncture cannula 1-2 and exit through the side perforation 1-2-2. The mesh 1-1 is connected to the puncture cannula 1-2 by setting a buckle 1-1-1 at the end of the mesh 1-1 that is larger than the plug hole. Specifically, the plug 1-2-4 can be inserted into the tail end of the puncture cannula 1-2, and then the two can be welded together using an ultrasonic welding machine. When connecting the mesh 1-1, the mesh 1-1 is passed through the plug hole of the plug 1-2-4 and then exits through the side perforation 1-2-2 on the side of the cannula. A buckle 1-1-1 is set at the end of the mesh 1-1, and the mesh 1-1 is pulled back to ensure that the mesh 1-1 will not come off. Compared to the original connection method, the plug design makes the connection between the mesh and the puncture cannula more convenient and secure. Furthermore, both ends of the mesh 1-1 are connected to extension sections made of silk or film. The buckle 1-1-1 is formed by knotting or melting the extension section to enlarge it. When using a knotted structure, multiple knots can be tied in the same position to ensure the knot size; when using a melt-enlargement structure, the extension section can be melted to shrink and enlarge it, thus forming a mushroom-shaped buckle 1-1-1. The extension section facilitates the subsequent fixation of the mesh and allows for connection to the puncture cannula through knotting or melting, making it convenient for clinical use.
[0042] [Example 2]
[0043] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as in Embodiment 1, except that:
[0044] like Figure 6 and Figure 7 As shown, in this embodiment, the first anti-retraction structure 1-2-3 is a single-turn spiral groove on the inner wall of the puncture cannula 1-2, and the second anti-retraction structure 2-2-1 is a single-turn spiral boss on the outer wall of the guide rod 2-2. The first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 can be forcibly squeezed and fastened together. Compared with the existing single-turn annular boss and groove design, the use of a spiral boss and spiral groove results in a longer axial engagement length, making the connection between the guide handle and the puncture cannula stronger and easier to assemble.
[0045] [Example 3]
[0046] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as those of Embodiments 1 and 2, except that:
[0047] In this embodiment, as an alternative method, the first anti-retraction structure 1-2-3 is a spiral groove provided on the inner wall of the puncture cannula 1-2, and the second anti-retraction structure 2-2-1 is a spiral boss provided on the outer wall of the guide rod 2-2. The combination of the first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 can achieve the same effect, that is, increase the firmness of the connection between the guide handle 2 and the puncture cannula 1-2, and prevent the problem of accidental disengagement due to force during operation.
[0048] [Example 4]
[0049] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as those in Embodiments 1 to 3, except that:
[0050] In this embodiment, the spiral bosses can be line segment bosses or protrusions spaced apart along the spiral direction, and the spiral grooves are continuous spiral grooves. For example... Figure 8 The diagram shows several protrusions spaced apart along the spiral direction. These protrusions cooperate with the continuous spiral grooves, increasing the firmness of the connection between the guide handle 2 and the puncture cannula 1-2. Furthermore, the production of the line segment bosses and protrusions is simple and convenient, ensuring the structural strength of the puncture cannula 1-2.
[0051] [Example 5]
[0052] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as in Embodiment 1, except that:
[0053] In this embodiment, the first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 are at least two interlocking annular locking structures with mutual concave and convex fits. The multi-ring annular locking structure increases the firmness of the connection between the guide handle and the puncture cannula, effectively preventing accidental detachment during operation due to force. Furthermore, the increased number of engagement points reduces the probability of detachment due to improper installation during assembly, significantly improving the success rate and safety of the surgery. Specifically, the first anti-retraction structure 1-2-3 is at least two annular protrusions axially spaced on the inner wall of the puncture cannula 1-2, and the second anti-retraction structure 2-2-1 is at least two annular grooves axially spaced on the outer wall of the guide rod 2-2. The first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 can be forcibly squeezed together, making the connection operation convenient and the connection firm and reliable. Both the annular grooves and annular protrusions are full-ring structures; that is, the annular grooves are full-ring grooves, and the annular protrusions are full-ring protrusions.
[0054] [Example 6]
[0055] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as those in Embodiment 5, except that:

The combination of the first anti-retraction structure 1-2-3 and the second anti-retraction structure 2-2-1 achieves the same effect: the multiple annular grooves and annular protrusions work together to increase the firmness of the connection between the guide handle 2 and the puncture cannula 1-2, preventing accidental detachment during operation.
[0057] [Example 7]
[0058] This embodiment provides a surgical instrument for urinary incontinence suspension surgery. Its basic structure and working principle are the same as those of Embodiments 5 and 6, except that:
[0059] In this embodiment, the annular boss can be a line segment boss or protrusion distributed at intervals along the circumference, and the annular groove is a continuous annular groove. The line segment boss or protrusion cooperates with the continuous annular groove, which increases the firmness of the connection between the guide handle 2 and the puncture cannula 1-2. Moreover, the line segment boss and protrusion are simple and convenient to manufacture, which can ensure the structural strength of the puncture cannula 1-2.
