[0002] In minimally invasive treatment of diseases such as pelvic floor dysfunction and stress urinary incontinence, the use of implants in conjunction with tissue anchors for mesh suspension or support has become a common clinical approach.

[0003] In existing technologies, the implant and tissue anchor usually require a number of independent connecting structural components for assembly, which leads to a high risk of inconsistency in the fit of each component. Furthermore, during the implantation of the tissue anchor, existing instruments cannot simultaneously provide effective internal support and puncture protection for the mesh cannula, making the mesh prone to collapse or displacement. The support and protection of the surgical operation are insufficient, and the operation is also more cumbersome for doctors when puncturing and delivering the mesh and adjusting the position of the implant.

[0004] Therefore, it is necessary to provide a new implant and delivery system to solve the aforementioned problems in the prior art. Summary of the Invention

[0005] The technical problem to be solved by this application is how to provide a structurally stable implant and delivery system that is easy to implant.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0028] The following is in conjunction with the appendix Figures 1-9The specific embodiments of the present invention will be further described in detail below.

[0029] The present invention provides an implant and a delivery system, wherein the implant is used to be implanted into a patient to assist in the treatment of incontinence, pelvic tissue prolapse and pelvic diseases, and the delivery system is used to implant the implant into the patient. Specifically, the implant includes a support body 100, a first extension 110 disposed opposite to the support body 100, a second extension 120 disposed opposite to the support body 100, an adjustment ring 300, a mesh sleeve 400 and a plurality of anchor structures 500.

[0030] In some embodiments, the support body 100, the first extension 110, and the second extension 120 each include multiple support units. Each support unit includes multiple connected support rods 200, and adjacent support units share one or more support rods 200. The multiple support units cooperate to form a mesh structure, so that the support body 100, the first extension 110, and the second extension 120 all have a mesh structure and a certain degree of extensibility to adapt to the internal environment of different implantation locations. Adjacent support units share one or more support rods 200 to connect adjacent support units to each other, thereby improving the stability of the support body 100 and the first extension 110.

[0031] In some specific embodiments, the support body 100, the first extension 110 and the second extension 120 can be formed into the structure of the above-mentioned multiple support rod components 200 by means of molding, die casting, laser etching, laser cutting, extrusion, etc., so as to form multiple support units, that is, the implant is an integral structure.

[0032] In some specific embodiments, the support body 100 is rectangular, with the first extension 110 disposed at two corners on one side of the support body 100, and the second extension 120 disposed on both sides of the support body 100.

[0033] In some specific embodiments, the support body 100, the first extension 110 and the second extension 120 are made of polyethylene material with a thickness of 0.1-0.2mm and are integrally formed by laser cutting and heat treatment, that is, the support rod component 200 is made of polyethylene material.

[0034] In some more specific embodiments, multiple support units within the support body 100 extend along a first direction and a second direction, respectively. The first direction and the second direction are perpendicular to each other. For example, the first direction is the direction extending along the X-axis, and the second direction is the direction extending along the Y-axis, making the support body 100 rectangular. Multiple support units within the first extension 110 extend along a third direction. The third direction has a first angle with the first direction and a second angle with the second direction. Specifically, the first extension 110 is located at the edge of the support body 100 and extends along the third direction. More specifically, two first extensions 110 are respectively located at two corners of the support body 100, and the support units within the first extension 110 are connected to the support units within the support body 100 by integral molding. Meanwhile, the angles between the first angle and the second angle can be the same or different. In this embodiment, it is preferable that the first angle and the second angle are the same, both being 45°.

[0035] In some more specific embodiments, the support unit can be triangular, rectangular, or rhomboid. In this embodiment, the support unit is rhomboid in shape. Specifically, the support unit includes two centrally symmetrical rhomboid structures. Each rhomboid structure includes four support rods 200 connected end-to-end. Two connected support rods 200 are first support rods 210, and the remaining two connected support rods 200 are second support rods 220. The first support rods 210 and the second support rods 220 are connected. More specifically, the two first support rods 210... The first support rod 210 is defined as support rod 1 and support rod 220 respectively. The two second support rods 220 are defined as support rod 3 and support rod 4 respectively. One end of support rod 1 is connected to support rod 2 and the other end is connected to support rod 4. One end of support rod 2 is connected to support rod 1 and the other end is connected to support rod 3. One end of support rod 3 is connected to support rod 2 and the other end is connected to support rod 4. In addition, the length of the first support rod 210 is greater than the length of the second support rod 220, and the two rhomboid structures share one first support rod 210. At the same time, the two rhomboid structures are arranged in a centrally symmetrical manner.

[0036] In some embodiments, the adjusting rings 300 are all disposed on the second extension 120, and the inner circumference of the adjusting ring 300 forms an adjusting hole 310. The outer circumference of the adjusting ring 300 is connected to multiple support rod members 200. Specifically, after the support body 100 and the second extension 120 are processed, the position on the second extension 120 where the adjusting ring 300 needs to be installed is cut by laser cutting. The cut shape is adapted to the shape of the outer wall of the adjusting ring 300, so as to facilitate the installation of the adjusting ring 300 to the support body 100. Specifically, installing the adjusting ring 300 to the second extension 120 means connecting the outer wall of the adjusting ring 300 to the support rod member 200. The connection method can be adhesive or snap-fit, etc., which is not limited here. The positions of the two extensions 120 remain unchanged. More specifically, the support body 100 has a first side, a second side, a third side, and a fourth side. The first and second sides are parallel to each other, and the third and fourth sides are parallel to each other. Both first extensions 110 are located on the first side, and both second extensions 120 are located on the third and fourth sides, respectively. The second extension 120 on the third side has an angle with the third side, which is 15-45°, preferably 30°. The second extension 120 on the fourth side also has an angle with the fourth side, which is 15-45°, preferably 30°. The inclined second extensions 120 decompose the traction force of the mesh sleeve 400 on the support body 100 into lateral and rearward components. This oblique traction and the first extensions 110 (anchored in the front) form a multi-point mechanical balance in three-dimensional space, preventing the support body from slipping or warping in a single plane. In addition, the inner circumference of the adjusting ring 300 forms an adjusting hole 310 to facilitate the installation of the mesh sleeve 400.

[0037] In some embodiments, the mesh sleeve 400 is movably disposed in the adjustment hole 310; specifically, the diameter of the mesh sleeve 400 is less than or equal to the diameter of the adjustment hole 310, so that the mesh sleeve 400 can be inserted into the adjustment hole 310 and move along the axial direction of the adjustment hole 310 within the adjustment hole 310 to cooperate with the support body 100 for implantation.

[0038] In some specific embodiments, the mesh sleeve 400 includes multiple circumferentially connected connecting units. Each connecting unit includes multiple connected connecting rods, and adjacent connecting units share one or more connecting rods. Specifically, the multiple connecting units cooperate to form a mesh structure, so that the mesh sleeve 400 has a mesh structure and a certain degree of extensibility to adapt to the internal environment of different implantation locations. Adjacent connecting units share one or more connecting rods to connect adjacent connecting units to each other, thereby improving the stability of the support body 100 and the first extension 110.

[0039] In some specific embodiments, since the mesh sleeve 400 is cylindrical, the connecting support rod is arranged in an arc shape so that multiple connecting units can be connected end to end in the circumference to form a circular structure, so as to form the mesh sleeve 400.

[0040] In some specific embodiments, since the mesh sleeve 400 is cylindrical, an angle is provided between two adjacent connecting rods in the circumferential direction, so that there is an angle between two adjacent connecting units in the circumferential direction, so that multiple connecting units can be connected end to end in the circumferential direction to form a circular structure, so as to form the mesh sleeve 400.

[0041] In some specific embodiments, the mesh sleeve 400 can be formed into the above-mentioned multiple connecting rods structure by means of molding, die casting, laser etching, laser cutting, extrusion, etc., so as to form multiple connecting units, that is, the implant is an integral structure.

[0042] In some specific embodiments, the mesh sleeve 400 is made entirely of 0.1-0.2mm thick polyethylene material and is integrally formed using laser cutting and heat treatment; that is, the connecting support rod is made of polyethylene.

[0043] In some embodiments, multiple anchor structures 500 are respectively disposed at the ends of each first extension 110 and each mesh sleeve 400, for driving the first extension 110 to connect with a first preset position, and driving the mesh sleeve 400 to connect with a second preset position after passing through the adjustment hole 310, so as to be inserted into the support body 100; specifically, the number of anchor structures 500 corresponds to the number of first extensions 110 and the number of mesh sleeves 400. In this embodiment, there are two first extensions 110 and two mesh sleeves 400, so there are four anchor structures 500; wherein, the anchor structure 500 corresponding to the first extension 110 is connected to the end of the first extension 110 away from the support body 100, thereby driving the first extension 110 to connect with a first preset position, and driving the mesh sleeve 400 to connect with a second preset position after passing through the adjustment hole 310, so as to be inserted into the support body 100. The first preset position is connected to the first preset position, i.e., implanted into the first preset position; the anchor structure 500 corresponding to the mesh sleeve 400 is connected to the end of the mesh sleeve 400, and the width of the anchor structure 500 corresponding to the mesh sleeve 400 is smaller than the diameter of the adjustment hole 310, so that the anchor structure 500 corresponding to the mesh sleeve 400 can pass through the adjustment hole 310. The anchor structure 500 corresponding to the mesh sleeve 400 is used to drive the mesh sleeve 400 through the adjustment hole 310 and connect to the second preset position, i.e., implant the mesh sleeve 400 into the second preset position. By inserting the first extension 110 directly into the first preset position, the mesh sleeve 400 is implanted into the second preset position, thereby completing the implantation of the support body 100, i.e., completing the implantation of the implant. It is worth noting that the first preset position and the second preset position are not limited here. In the actual implantation process, the first preset position and the second preset position are determined according to the implantation requirements.

[0044] In some embodiments, to facilitate the connection between the anchor structure 500 and the first extension 110 or the mesh sleeve 400, and to facilitate the implantation of the anchor structure 500, the anchor structure 500 includes a puncture portion 510, a connecting portion 520, and a cover plate 530. The puncture portion 510 has an end and an end, and the end of the puncture portion 510 is connected to the connecting portion 520. The connection method can be adhesive, snap-fit, or integral molding, etc. In this embodiment, integral molding is preferred. The end of the puncture portion 510 is pointed, forming a first tip 511 for puncture. That is, during implantation, the first tip 511 drives the connecting portion 520 to be implanted, facilitating the implantation process. The sidewall of the connecting portion 520 has a connecting groove 521. Specifically, the connecting portion 520 has a first wall, a second wall, a third wall, and a fourth wall connected sequentially. The four walls, and the first end face and the second end face at both ends, wherein the first end face is connected to the puncture part 510; the connecting groove 521 is opened in the first wall and the connecting groove 521 passes through the second wall, the fourth wall and the second end face; the cover plate 530 is detachably provided in the connecting groove 521. Specifically, the end face of the cover plate 530 is provided with multiple snap-fit ​​rods, and the bottom wall of the connecting groove 521 is provided with multiple snap-fit ​​holes. The multiple snap-fit ​​holes correspond one-to-one with the multiple snap-fit ​​rods, and the snap-fit ​​rods and snap-fit ​​holes are snapped together so that the cover plate 530 is detachably provided in the connecting groove 521. During the process of fixing the first extension 110, the end of the first extension 110 is placed between the cover plate 530 and the connecting groove 521, and the cover plate 530 and the connecting groove 521 are snapped together, so that the end of the first extension 110 is snapped between the cover plate 530 and the connecting groove 521 so that the anchor structure 500 can drive the first extension 110 to move. More specifically, to facilitate the connection between the anchor structure 500 and the mesh sleeve 400, arc-shaped grooves 540 are provided at the ends of the connecting part 520 and the cover plate 530. That is, an arc-shaped groove 540 is provided on the second end face of the cover plate 530, and the end face of the arc-shaped groove 540 is connected to the connecting groove 521. At the same time, an arc-shaped groove 540 is also provided on the end face of the cover plate 530 facing the connecting groove 521. The cross-section of the two arc-shaped grooves 540 is semi-circular. When the cover plate 530 is connected to the connecting groove 521, the two arc-shaped grooves 540 connect to form a circle to accommodate the mesh sleeve 400. In addition, the diameter of the circle formed by the two arc-shaped grooves 540 is less than or equal to the diameter of the mesh sleeve 400, so as to secure the mesh sleeve 400 and prevent the mesh sleeve 400 from falling out of the circular structure formed by the two arc-shaped grooves 540, thereby facilitating the movement of the mesh sleeve 400 by the anchor structure 500.

[0045] In some specific embodiments, to enhance the stability of the anchor structure 500 after implantation, an installation groove 512 is formed at the end of the puncture portion 510. The installation groove 512 has a first sidewall 513, a second sidewall 514, and a third sidewall 515. Specifically, the installation groove 512 penetrates the puncture portion 510 along its thickness direction, so that the installation groove 512 only has the first sidewall 513, the second sidewall 514, and the third sidewall 515. The second sidewall 514 is parallel to the end of the connecting portion 520 to connect with it, that is, the second sidewall 514 is parallel to the first end face, thereby facilitating the connection between the connecting portion 520 and the puncture portion 510. The first sidewall 513 and the third sidewall 515 are both inclined and parallel to the puncture portion 510. The outer wall of the puncture portion 510 forms a second tip 516. Specifically, both the first sidewall 513 and the second sidewall 514 extend in a direction away from the first tip 511. Taking the first sidewall 513 as an example, the first sidewall 513 has an angle with the second wall on the connecting portion 520 and extends in a direction away from the first tip 511. At the same time, the first sidewall 513 also tends to move away from the second wall so that the first sidewall 513 will contact the outer wall of the puncture portion 510 during the extension process, thereby forming the second tip 516. Since the first sidewall 513 tends to move away from the second wall, the second tip 516 is spaced from the connecting portion 520. During the puncture process, the second tip 516 can prevent the anchor structure 500 from leaving the puncture position, thereby ensuring the stability of the implantation.

[0046] In some embodiments, to facilitate the insertion of the anchor structure 500, a guide hole 522 is provided on the sidewall of the connecting groove 521. The guide hole 522 extends to the first tip 511, and the diameter of the guide hole 522 increases along the direction from the first tip 511 toward the connecting portion 520. Specifically, the connecting groove 521 has only one sidewall and one bottom wall, so the guide hole 522 is located on the sidewall of the connecting groove 521, that is, the sidewall of the connecting groove 521 is parallel to the first end face. At the same time, the guide hole 522 extends from the sidewall of the connecting groove 521 toward the first tip 511. Since the first tip 511 is pointed, the diameter of the guide hole 522 increases along the direction from the first tip 511 toward the connecting portion 520, that is, the diameter of the guide hole 522 decreases from the sidewall of the connecting groove 521 toward the first tip 511, so that the guide hole 522 will not penetrate the sidewall of the first tip 511. More specifically, in order to To facilitate the implantation of the anchor structure 500, a guide groove 523 is provided on the side wall of the connecting part 520. The guide groove 523 communicates with the guide hole 522. The guide groove 523 includes a first groove structure and a second groove structure. The first groove structure is rectangular, and the second groove structure communicates with the first groove structure and is arc-shaped. More specifically, the second groove structure is located on the side of the first groove structure facing the first tip 511 and communicates with the first groove structure. During the implantation of the anchor structure 500, a delivery handle 600 is used to move the anchor structure 500. The delivery handle 600 has a bent delivery pin 610. The delivery pin 610 passes through the first groove structure and enters the guide hole 522, thereby facilitating the movement of the anchor structure 500. The second groove structure is used to limit the position of the delivery pin 610 to reduce the possibility of the delivery pin 610 swaying within the second groove structure.

[0047] An embodiment of this application discloses a delivery system including a delivery handle 600, a delivery structure, a support structure 700, and the aforementioned implant.

[0048] In some embodiments, the delivery handle 600 has a curved delivery pin 610, which is movably connected to the guide hole 522 of the anchor structure 500 to insert the anchor structure 500 into a first preset position or a second preset position. Specifically, one end of the delivery pin 610 is located at the end of the delivery handle 600. The pin can be snap-fitted, glued, or integrally molded, etc., and there are no specific limitations here. The main point is that there will be no relative movement between the delivery pin 610 and the delivery handle 600. The delivery pin 610 is curved to facilitate the control of the delivery pin 610 from the guide groove 523 into the guide hole 522 and extending along the guide hole 522, thereby facilitating the movement of the anchor structure 500 for insertion.

[0049] In some embodiments, the support structure 700 is movably disposed inside the mesh sleeve 400 to support the mesh sleeve 400 and prevent it from collapsing. Specifically, the support structure 700 includes a support handle 710, a support rod 720, and a support fixing head 730. The support rod 720 is disposed at the end of the support handle 710, and its arrangement can be snap-fit, glued, or integrally formed, etc., without limitation, as long as there is no relative movement between the support rod 720 and the support handle 710. The support rod 720 is moved by holding the support handle 710. The support fixing head 730 is spaced apart from the support rod 720 and is used to abut against the inner wall of the mesh sleeve 400 after the support rod 720 extends into the mesh sleeve 400 to support the mesh sleeve 400. In this example, two support fixing heads 730 are selected and are spaced apart on the support rod 720. The setting method can be snap-fit, adhesive, or integral molding, etc., which is not limited here. The main point is that the two will not move relative to each other. The ends of the support fixing heads 730 are arc-shaped to facilitate the insertion of the support fixing heads 730 into the mesh sleeve 400. During the implantation process, the two support fixing heads 730 are first inserted into the mesh sleeve 400 by controlling the support handle 710. The diameter of the support fixing heads 730 is less than or equal to the diameter of the mesh sleeve 400 to support the mesh sleeve 400 and prevent the mesh sleeve 400 from collapsing. After the implantation is completed, the support fixing heads 730 are removed by controlling the support handle 710.

[0050] In some embodiments, the conveying structure is used to fix the mesh sleeve 400 after it is implanted. Specifically, the conveying structure includes a conveying clamp 810 and a fixing buckle 820 disposed opposite to each other. The conveying clamp 810 includes a first clamping rod and a second clamping rod. One end of the first clamping rod and the second clamping rod are connected, and the connection method can be bonding, welding, or integral molding, etc., which will not be elaborated here. The other ends of the first clamping rod and the second clamping rod are spaced apart to form a clamping end for easy clamping. The end of the conveying clamp 810 is provided with a clamping block 811. Specifically, both the clamping ends of the first clamping rod and the second clamping rod are provided with clamping blocks 811, and the arrangement method can be bonding, snapping, or integral molding, etc. In this embodiment, it is preferred to... An integral molding method is adopted; a clamping groove 821 is formed through the fixed buckle 820 to accommodate the clamping block 811. Specifically, the clamping groove 821 passes through the fixed buckle 820 along the thickness direction. During the clamping process, the clamping block 811 is controlled to pass through the clamping groove 821, thereby facilitating the operation of the conveying caliper 810 to drive the fixed buckle 820 to move. More specifically, in order to facilitate the conveying caliper 810 to drive the fixed buckle 820 to move, the clamping block 811 is set to have the same cross-sectional size as the clamping groove 821 or the cross-sectional area of ​​the clamping block 811 is slightly larger than the cross-sectional area of ​​the clamping groove 821, so as to reduce the possibility of the fixed buckle 820 disengaging from the clamping block 811 during the movement of the fixed buckle 820.

[0051] In some specific embodiments, in order for the fixing buckle 820 to restrict the position of the mesh sleeve 400, a locking rod 822 and a locking groove 823 are provided on the side wall of the fixing buckle 820. The locking rod 822 can be provided by bonding, snap-fitting, or integral molding, etc. In this embodiment, integral molding is preferred. The cross-sectional shape of the locking groove 823 is the same as the cross-sectional shape of the locking rod 822, so that the locking rod 822 and the locking groove 823 of the oppositely positioned fixing buckle 820 can cooperate, thereby connecting the oppositely positioned fixing buckles 820. Specifically, when the first clamping rod and the second clamping rod are operated to approach each other, since the first clamping rod is located near the second clamping rod, the locking rod 822 and the locking groove 823 of the oppositely positioned fixing buckle 820 can cooperate, thereby connecting the oppositely positioned fixing buckles 820. The fixing buckle 820 of the clamping rod and the fixing buckle 820 of the second clamping rod are centrally symmetrical. Therefore, the position of the locking rod 822 on the fixing buckle 820 of the first clamping rod corresponds to the position of the locking groove 823 on the fixing buckle 820 of the second clamping rod, and the position of the locking groove 823 on the fixing buckle 820 of the first clamping rod corresponds to the position of the locking rod 822 on the fixing buckle 820 of the second clamping rod. When the first clamping rod and the second clamping rod are brought closer to each other, the locking rod 822 on the fixing buckle 820 of the first clamping rod extends into the locking groove 823 on the fixing buckle 820 of the second clamping rod, thereby engaging the two fixing buckles 820. In addition, a semi-circular groove 824 is provided on the side wall of the fixing buckle 820, and the semi-circular groove 824 is placed between the locking rod 822 and the locking groove 823, so that after the fixing buckles 820 are engaged, they form a circle to accommodate the mesh sleeve 400. Specifically, the diameter of the circular structure formed by the two semi-circular grooves 824 is less than or equal to the diameter of the mesh sleeve 400, so as to clamp the mesh sleeve 400. At the same time, the width of the structure formed by the two fixing buckles 820 after engagement is greater than the diameter of the adjustment hole 310, so that the support body 100 will not detach from the mesh sleeve 400. In addition, it is worth noting that after the fixing buckles 820 are engaged, the excess mesh sleeve 400 needs to be removed. This is known to those skilled in the art and will not be described in detail here.

[0052] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims. Furthermore, the invention described herein may have other embodiments and can be implemented or carried out in various ways.
