Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and more particularly, to a mesh sleeve implant with multiple suture holes. BACKGROUND

[0002] The rotator cuff, also known as the Rotator Cuff or Musculotendinous Cuff, is a structure composed of four muscles and their tendons in the shoulder. These muscles include the Supraspinatus, Infraspinatus, Teres Minor, and Subscapularis. Together, they form a structure similar to a "cuff" that covers the humeral head and the scapula. The primary function of the rotator cuff is to stabilize the shoulder joint by compressing the humeral head within the glenoid fossa of the scapula. Additionally, the rotator cuff muscles play a crucial role in various shoulder movements and help prevent impingement of the humeral head on the acromion.

[0003] Insertion refers to the point where a muscle or tendon attaches to a bone. For example, Tendon Insertion is the point where a tendon connects to a bone, which is a critical area for transmitting muscle force to the bone. For the rotator cuff tendons, their insertions are primarily on the anatomical neck and greater and lesser tuberosities of the proximal humerus. ACL Insertion refers to the points where the Anterior Cruciate Ligament (ACL) attaches to the bone, which plays a crucial role in the stability of the knee joint. PCL Insertion refers to the points where the Posterior Cruciate Ligament (PCL) attaches to the bone, which also plays a crucial role in the stability of the knee joint.

[0004] Rotator cuff tears and insertion avulsion fractures can be caused by acute trauma, chronic overuse, and other factors. Rotator cuff repair surgery and insertion avulsion fracture reduction and internal fixation surgery are common surgical treatment options. In the above procedures, the suturing of the edges of a rotator cuff tear and the suturing of tendon stumps to the insertion area are performed. Currently, the primary consideration in performing these suturing procedures is to improve the prognosis and reduce the rate of future rotator cuff tears and insertion avulsion fractures. However, the impact of the quality of the suture line on the aesthetic appearance of the patient is often overlooked. As a result, uneven tension caused by the suture line in the suture area often leads to a "cat ear" appearance.

[0005] Chinese patent application CN119279855A discloses an artificial shoulder sleeve patch and weaving method, which includes an upper layer weaving structure (1), a middle layer weaving structure (2) for carrying drugs, and a lower layer weaving structure (3) arranged in a stack from top to bottom. The patch edge forms a circle of lock edge fixing structure (4), and multiple lock holes (5) are arranged on the inner side of the lock edge fixing structure (4), which form a ring. However, the shoulder sleeve patch of this patent application depends on a circle of lock edge fixing structure (4) on the edge for fixation. When the shoulder sleeve patch is fixed at the fracture site of the shoulder sleeve tear and the insertion point, a wrinkle deformation area will inevitably be generated. Due to the frequent movement of the shoulder sleeve, it is difficult for the shoulder sleeve patch, especially the wrinkle part, to completely press the tendon of the suture area, thereby failing to improve the "cat ear" concave-convex condition of the suture area.

[0006] Therefore, it is urgent to provide a mesh sleeve implant with multiple suture holes to solve the technical problem of uneven suture area "cat ear" concave-convex caused by uneven wiring tension in the suture operation of the shoulder sleeve tear edge and the suture of the tendon stump and the insertion point area. SUMMARY

[0039] In addition, the second hole is arranged adjacent to the partition wall region with the largest number of first holes, and the force of the second hole fixed with the soft tissue through the suture wire can be evenly distributed to the first holes adjacent to the partition wall region, which is beneficial to make the mesh cage in a relatively stable state, and can effectively avoid the "cat ear" concave-convex caused by uneven wire tension in the prior art.

[0040] (2) The present invention provides a mesh-type implant with multiple suturing holes. By arranging a plurality of the first holes in an array and setting the range of their inner diameter values, the mesh-type implant can provide relatively uniform pressing force and permeability in all directions, ensuring overall fit with the soft tissue and enabling the exchange of substances between the interior of the mesh-type implant and the external environment, thereby facilitating the circulation of tissue fluids, etc., promoting the growth and repair of surrounding tissues, and avoiding the accumulation of local metabolic products.

[0053] The various aspects of the present application are further described in detail below.

[0054] Unless otherwise defined or specified, all professional and scientific terms used herein have the same meaning as those familiar to one of ordinary skill in the art. In addition, any method and material similar or equivalent to those described herein can be used in the present application.

[0055] In order to more clearly illustrate the technical solutions of the embodiments of the present disclosure or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application, and for those of ordinary skill in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0056] It should also be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present disclosure in a schematic manner, and only show the components related to the present application in the diagrams, not the number, shape and size of the components when actually implemented. The actual implementation of each component may be a random change in shape, number and proportion, and the layout pattern of the components may also be more complex. For example, the thickness of the elements in the drawings can be exaggerated for clarity.

[0057] Embodiment 1

[0058] Existing suture surgeries for rotator cuff tears or avulsions usually align the tear edges (Margin Convergence) before suturing, for example: producing crescent-shaped, U-shaped, or L-shaped tears (non-massive tears) as defined by Davidson and Burkhart, or producing massive tears (Massive Tear). However, current suturing rarely considers the impact of the wiring quality of the suture area on the patient's later appearance, which generally leads to uneven wiring tension and "cat ear"-like bumps in soft tissues such as tendons. After the patient recovers, the "cat ear"-like bumps will cause the skin surface to be uneven.

[0059] like Figures 1-2 As shown, in the crescent-shaped rotator cuff tear suture surgery, the suture 1 carried by the inner row of anchors 2 is fixed to the humeral bone 4 by the outer row of anchors 9 after cross-wiring. Under the pulling and pressing action of the cross-wiring, the tendon 3 that contacts the suture 1 is subjected to greater tension, while the tendon 3 that does not contact the suture 1 is subjected to less tension. The portion of the tendon 3 that is subjected to less tension forms an upward bulge, which leads to the generation of a "cat ear"-shaped bump 5.

[0060] In order to solve the above technical problems in the prior art, the present invention proposes a mesh-type implant with multiple suture holes, comprising:

[0061] An internal implant body 6, the internal implant body 6 being a flexible sheet and having a first surface and a second surface opposite to each other;

[0062] First holes 7, a plurality of first holes 7 arranged in an array pass through the first surface and the second surface, and adjacent first holes 7 are separated by partition walls on the implant body 6;

[0063] Second holes 8, a plurality of second holes 8 are provided in the partition wall region, the second holes 8 pass through the first surface and the second surface, and the second holes 8 are not connected to the first holes 7; wherein,

[0064] The second hole 8 is a hole for threading the suture thread 1 , and the second hole 8 is different from the first hole 7 .

[0065] It should be noted that the mesh-type implant with multiple suture holes of the present invention can be tightly pressed onto the tear edge alignment of the aforementioned rotator cuff tear or end point avulsion, so that the soft tissue at the tear edge (for example, tendon, etc.) is completely wrapped and attached to one side of the mesh-type implant with multiple suture holes in the reset position, thereby effectively avoiding the existing "cat ear"-like bumps caused by uneven wiring tension.

[0066] It is to be noted that the partition wall region refers to the part of the implant body 6 for partitioning the plurality of first holes 7, which includes the part of the implant body 6 between two adjacent first holes 7 and the part of the implant body 6 at the intersection of the plurality of partition walls.

[0067] In some embodiments, the first holes 7 are arranged in a uniform array on the implant body 6. The inner diameter of the first holes 7 ranges from 2.6 mm to 5 mm. Preferably, the inner diameter of the first holes 7 ranges from 2.7 mm to 4.9 mm; more preferably, from 2.8 mm to 4.8 mm; more preferably, from 2.9 mm to 4.7 mm; more preferably, from 3.0 mm to 4.6 mm; more preferably, from 3.1 mm to 4.5 mm; more preferably, from 3.2 mm to 4.4 mm; more preferably, from 3.3 mm to 4.3 mm; more preferably, from 3.4 mm to 4.2 mm; more preferably, from 3.5 mm to 4.1 mm; more preferably, from 3.6 mm to 4 mm; more preferably, from 3.7 mm to 3.9 mm; more preferably, from 3.8 mm.

[0068] It is to be noted that the arrangement of the plurality of first holes 7 in an array and the range of the inner diameter of the first holes 7 can provide relatively uniform compression and permeability in all directions, which can ensure overall adhesion to soft tissue and allow material exchange between the inside and outside of the mesh implant, facilitating the flow of tissue fluid and promoting the growth and repair of surrounding tissue, thereby avoiding the accumulation of local metabolic products. Specifically, if the pore size is too small (e.g., less than 2.6 mm), the flow of tissue fluid is limited and the discharge of metabolic products is not smooth; if the pore size is too large (e.g., greater than 5 mm), the compression strength of the implant is weakened.

[0069] In addition, the arrangement of the first holes 7 can provide a sufficient observation field of view for the surgical operator, which facilitates the adjustment of the compression state of the mesh implant during the suturing process.

[0070] In some embodiments, the second holes 8 are arranged at the partition wall region where the number of first holes 7 is the largest.

[0071] It should be noted that when the plurality of second holes 8 are arranged in an array, the second holes 8 are distributed in the central and peripheral regions of the mesh implant, so that the surgeon can select the second holes 8 to which the suture 1 is attached according to the shape of the tear. Through this operation, the suture 1 attached to the second hole 8 can be fixed to the soft tissue (e.g., tendon) to be sutured, thereby ensuring that the mesh implant completely presses and fits the tear. In addition, the second hole 8 is arranged in the region of the partition wall adjacent to the first hole 7 with the largest number, and compared with the second hole 8 arranged in the partition wall between two adjacent first holes 7, the force of the suture fixed to the soft tissue by the second hole 8 can be more evenly distributed to all the first holes 7 adjacent to the partition wall region, rather than only pulling the two adjacent first holes 7, which is beneficial to make the mesh implant in a more stable state.

[0072] In a more preferred case, one second hole 8 is arranged in each region of the partition wall adjacent to the first hole 7 with the largest number, because the higher the arrangement density of the second hole 8 is, the more advantageous it is for this embodiment. In addition, the region of the partition wall adjacent to the first hole 7 with the largest number is also the intersection of the plurality of partition walls.

[0073] In some embodiments, the shape of the second hole 8 as a suture hole is circular, and the inner diameter of the second hole 8 is in the range of 1.5mm-2.5mm, so that the suture 1 has enough space to pass through.

[0074] Preferably, the mesh implant is made by a weaving process or a non-weaving process. Preferably, the inner diameter of the second hole is in the range of 1.6mm-2.4mm; more preferably, in the range of 1.7mm-2.3mm; more preferably, in the range of 1.8mm-2.2mm; more preferably, in the range of 1.9mm-2.1mm; more preferably, 2.0mm.

[0075] It should be noted that in the selection of the suture 1, the commonly used suture 1 can be a suture suitable for suturing thicker fascia, muscle and other tissues (such as fixing the rotator cuff tendon in the rotator cuff tear surgery), and the diameter and strength of the suture 1 are advantageous for cooperating with the mesh implant to form the final structure. suture, suture and the like, and the diameter and strength of the suture 1 are advantageous for cooperating with the mesh implant to form the final structure.

[0076] In some embodiments, the material of the flexible sheet is selected from one or more combinations of polyethylene terephthalate, polypropylene, polyethylene, polylactic acid, polyglycolic acid, polycaprolactone, chitosan, silk fibroin, polytetrafluoroethylene, polyether ether ketone, natural fiber, high-density polyethylene, and ultra-high molecular weight polyethylene. In this way, not only does the mesh implant have excellent biocompatibility, but also has ideal mechanical strength.

[0077] In some embodiments, the mesh implant is in the form of a flat ribbon. This configuration is advantageous for compressing and fitting complex rotator cuff tears. Preferably, the flat ribbon-shaped mesh implant is provided with graduated markings, thereby facilitating the surgeon's tailoring of the implant to the optimal shape.

[0078] In some embodiments, the mesh implant is produced by a weaving process or a non-woven process. In the weaving process, yarns or filamentary materials may be interwoven according to the arrangement of the first holes 7 and the second holes 8 to form a woven mesh implant, for example, using a plain or twill weave. This process can be performed using a weaving machine. In the non-woven process, the mesh implant can be produced by laser cutting, hot pressing, compression molding, 3D printing, or the like.

[0079] In some embodiments, as shown in the attached Figures 3-7 As shown, the shape of the first hole 7 is not particularly limited, and it can be selected from any one of a circle, a rectangle, a parallelogram, a trapezoid, and a regular polygon.

[0080] In some embodiments, as shown in the attached Figures 8-9 As shown, the shape of the first holes 7 is selected from an equilateral triangle, and adjacent first holes 7 are spliced ​​together to form a parallelogram. Specifically, the stability of the triangle is beneficial for the use of the mesh-type implant with multiple suture holes of the present invention; and the splicing of adjacent first holes 7 to form a parallelogram shape further optimizes the array arrangement of the first holes 7, amplifying the effect of evenly distributing the force of the second holes 8 fixed to the soft tissue via the sutures to the first holes 7 adjacent to the septal wall area.

[0081] In some embodiments, the inner angles of the equilateral triangle-shaped first holes 7 are rounded, which allows the partition walls at the rounded inner angles of adjacent first holes 7 to have better mechanical strength and deformation resistance than when no rounded inner angles are provided.

[0082] In some embodiments, biomaterials such as blood, blood components, BMA, BMSC, PRP, ACP and / or growth factors can be injected into the implant body to improve and accelerate tear and tissue healing.

[0084] like Figure 10 As shown, the present invention also provides a method for implanting a mesh-type implant with multiple suture holes, comprising:

[0085] Step 1. Provide a plurality of inner row anchors 2 with sutures and a plurality of outer row anchors 9;

[0086] Step 2. Implanting an inner row anchor 2 into the interior of the bone, and the free end of the suture of the inner row anchor 2 is sequentially threaded through the soft tissue to be reduced and the second hole 8;

[0087] Step 3. Repeating Step 2 for all inner row anchors 2;

[0088] Step 4. Using the sutures 1 of several inner row anchors 2 to pull the soft tissue to the position to be reduced;

[0089] Step 5. Threading the free end of the suture 1 of the inner row anchor 2 through the second hole 8 again;

[0090] Step 6. The free end of the suture threaded through the second hole 8 is fixed into the interior of the bone 4 by an outer row anchor 9 to press the soft tissue flat onto the reduced position, completing the implantation of the mesh-like endoprosthesis; wherein,

[0091] The second hole 8 in Step 2 and the second hole 8 in Step 5 are at different positions.

[0092] It should be noted that the inner row anchor with a suture 1 can be made of a biocompatible material such as polyester fiber (PET) or polyether ether ketone (PEEK) to form a full-suture anchor (e.g., SutureTak anchor), or made of a bioabsorbable material such as polylactic acid to form a bioabsorbable anchor, or made of a composite absorbable material to form a composite absorbable anchor, or made of polyethylene material to form a Q-Fix anchor, or made of stainless steel or titanium alloy to form a metal anchor, etc.

[0093] In some embodiments, the second hole 8 in Step 2 and the second hole 8 in Step 5 are distributed on both sides of the reduced position of the soft tissue, and the implantation positions of the inner row anchor and the outer row anchor 9 are distributed on both sides of the reduced position of the soft tissue.

[0094] In some embodiments, the soft tissue is a tendon 3.

[0095] In some embodiments, the flat and band-shaped mesh-like endoprosthesis is provided with a cutting scale mark. The mesh-like endoprosthesis with multiple suture holes can be cut by the surgical operator to match the shape of the irregular tear to reduce the amount of the mesh-like endoprosthesis with multiple suture holes used in the case of completely pressurized and fitted irregular tear such as a large rotator cuff tear. As shown in the accompanying drawings, in the case of an irregular large rotator cuff tear (the tear shown is a reverse "T" shape), the mesh-like endoprosthesis can be cut according to the shape of the complex tear, and then implanted and fixed according to the implantation method of the present embodiment.
