Description

Technical Field

[0001] This utility model relates to the field of materials technology, and in particular to a PET patch for shoulder joint support. Background Technology

[0002] The function of the rotator cuff is to pull the humeral head towards the glenoid fossa during upper arm abduction, maintaining the normal fulcrum joint between the humeral head and the glenoid fossa. Rotator cuff injuries will weaken or even eliminate this function, severely affecting upper limb abduction. Rotator cuff tears can cause pain during arm movement, reduced range of motion, limited function, or even immobility. Rotator cuff patches are surgically connected to the humeral head and glenoid fossa, providing support for rotator cuff repair.

[0003] Publication number CN 105125318 B discloses a segmented woven biomimetic artificial rotator cuff patch, wherein the rotator cuff patch is configured with growth-promoting materials to enhance the intrinsic healing potential of the tendon. Also, publication number CN118542975A discloses a rotator cuff patch and its preparation method.

[0004] However, some existing rotator cuff patches are made of dissolvable materials, and their dissolution time varies from person to person. Some rotator cuff patches dissolve before the patient has fully recovered, leading to the technical problem of needing a second rotator cuff surgery. Furthermore, the size of the rotator cuff varies from person to person, and rotator cuff patches with fixed holes may cause size mismatch issues during surgery, thus requiring improvement.

[0027] like Figures 1 to 3 As shown, this utility model provides a PET patch for shoulder joint intra-articular support, which is woven from PET material. PET (polyethylene terephthalate) material is processed into a yarn structure, the yarn is twisted, and further, the twisted yarn is woven to form the main structure of the patch. The patch is made of PET material, which reduces the risk of dissolution and provides high overall structural strength, allowing it to replace some tendon functions.

[0028] The shoulder joint PET patch includes a fixed section 14 and a traction section 13 arranged opposite to each other. The fixed section 14 and the traction section 13 are located at the two ends of the patch body 10, respectively. The fixed section 14 is used to connect to the glenoid cavity, and the traction section 13 is used to connect to the humeral head.

[0029] The traction section 13 includes two spaced-apart traction holes 11, each with a reinforcing wire 12 woven into its edge. The two traction holes 11 allow the traction wire to pass through, pulling the humeral head towards the glenoid fossa. The periphery of the traction holes 11 is locally reinforced with the reinforcing wire 12, thus preventing damage or tearing of the patch body 10 during traction, and improving the structural stability and traction position stability of the patch.

[0030] Preferably, the reinforcing wire 12 is arranged in a loop around the edge of the traction hole 11 to enhance local reinforcement in the edge area of ​​the traction hole 11, thereby increasing tensile strength without increasing material cost or thickness variation in other areas of the patch body 10. Preferably, the reinforcing wire 12 is made of PET material. The reinforcing wire 12 is made of the same material as the patch body 10 and can form local reinforcement at the edge of the traction hole 11 without generating additional interference factors during use.

[0031] In one embodiment, the length of the patch body 10 is 25mm-35mm. The length of the patch body 10 can serve as an auxiliary connection length between the humeral head and the glenoid cavity, and can replace part of the tendon function. Preferably, the length of the patch body 10 can be set to 25mm, 26mm, 28mm, 30mm, 32mm, or 35mm.

[0032] The main body of the patch 10 can be selected in appropriate length according to different bone sizes.

[0033] The width of the patch body 10 is 20mm-35mm, and the width of the patch body 10 can cover the lateral dimension of the connecting part to achieve adjustment of the coverage area of ​​the patch body 10. Optionally, the width of the patch body 10 can be set to 20mm, 22mm, 25mm, 28mm, 30mm, 32mm, or 35mm.

[0034] The thickness of the PET patch for the shoulder joint is 2mm-3.5mm. The patch body 10 is located in the top space between the humeral head and the glenoid cavity, and the thickness of the patch body 10 can be set to 2mm, 2.5mm, 3mm, 3.2mm, or 3.5mm.

[0035] Specifically, the patch body 10 can have length*width*thickness dimensions of: 25mm*25mm*2mm; 25mm*25mm*3mm; 25mm*20mm*2mm; 25mm*20mm*2mm, etc.

[0036] The traction hole 11 penetrates the patch body 10. The diameter of the traction hole 11 is 2mm-4mm. Optionally, the diameter of the traction hole 11 is 2mm, 2.5mm, 2.8mm, 3mm, 3.2mm, 3.5mm, 4mm and others.

[0037] Two traction holes 11 are spaced apart, with a hole spacing of 12 mm to 20 mm. Optionally, the spacing between the two traction holes 11 can be 12 mm, 12.5 mm, 15 mm, 16 mm, 18 mm, 20 mm, or other values.

[0038] The minimum distance between the edge of the traction hole 11 and the end edge of the traction section 13 is 2mm-3mm. The end of the traction section 13 is the edge position opposite to the fixed section 14. The edge of the traction hole 11 is reinforced with reinforcing wire 12, forming a reinforced edge. The minimum distance between the edge of the traction hole 11 and the end edge of the traction section 13 is 2mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, 3mm, or others.

[0039] like Figures 1 to 4 As shown, in one embodiment, the shoulder joint intra-articular PET patch includes an auxiliary line 20 that passes through the traction hole 11. The auxiliary line 20 is made of a water-soluble material. The auxiliary line 20 penetrates the patch body 10 and can pass through the traction hole 11 to guide the traction rope connected to the traction hole 11. The auxiliary line 20 is made of a water-soluble material, which dissolves after traction is completed, eliminating the need for secondary removal and improving ease of use. Furthermore, the auxiliary line 20 passes through the traction hole 11, and one end of the auxiliary line 20 can be pre-tied to the traction rope externally, providing ample operating space. Subsequently, the auxiliary line 20 is pulled to drive the traction rope through the hole, improving threading efficiency. Optionally, the auxiliary line 20 is made of polyvinyl alcohol (PVA) fiber.

[0040] In a preferred embodiment, a marking portion 16 is provided on the front side of the patch body 10. The marking portion 16 can identify the front or back of the patch body 10, facilitating consistent contact during use. Optionally, the marking portion 16 includes a texture and / or color provided on the surface of the patch body 10, the texture including, but not limited to, graphic symbols, text symbols, and texture colors. For example, a cross-shaped graphic mark is provided on the surface of the patch body 10; or, different colored threads are used to mark one side of the surface of the patch body 10.

[0041] Preferably, the marking part 16 may be disposed in one of the following areas: the traction section 13, the fixing section 14, or the patch body 10.

[0042] In an optional embodiment, the fixation segment 14 is used to connect to one end of the glenoid cavity. Optionally, the woven portion of the fixation segment 14 has perforated slots. The fixation segment 14 has a flat structure that can conform to the bone surface. The fixation segment 14 can be directly perforated or threaded with instruments to adapt to different user groups, improving ease of use and reliability of traction dimensions.

[0043] The wire diameter used in the fixed section 14 is smaller than that of the traction hole 11, which facilitates wire threading and fixing.

[0044] In another alternative embodiment, the fixing section 14 is provided with two or more fixing holes 15, the diameter of the fixing holes 15 being smaller than the diameter of the traction holes 11, so as to reduce the pulling force of a single fixing hole 15.

[0045] The number of fixing holes 15 is set to multiple, and they are spaced apart along the width direction of the patch body 10. Optionally, two or more fixing holes 15 are in the same straight line, and the spacing between the edges of the multiple fixing holes 15 and the edge of the fixed segment is consistent. For example, the number of fixing holes 15 can be set to four, six, eight, or ten.

[0046] In another embodiment, at least some of the fixing holes 15 are located on different straight lines and are staggered to accommodate the requirements of threading wires of different sizes. For example, two or more fixing holes 15 are distributed in two rows, and the two rows of fixing holes 15 are staggered. Each row is provided with two or more fixing holes 15, and the fixing holes 15 in adjacent rows are staggered to form intersecting or staggered lines or lines at different positions, so as to improve the convenience of connection and the reliability of force bearing of the fixing segment 14.

[0047] Preferably, the minimum distance between the fixing hole 15 and the edge of the fixing section 14 is greater than 2.5 mm. The end of the fixing section 14 is the edge position opposite to the traction section 13. The minimum distance between the edge of the fixing hole 15 and the end edge of the fixing section 14 is 2.5 mm, 2.6 mm, 2.8 mm, 3 mm, or others. The edge of the fixing hole 15 is reinforced with reinforcing wire 12, forming a reinforced edge.

[0048] In a preferred embodiment, the patch body 10 is processed using a weaving process with warp and weft twisted yarns to form a flat, elongated PET patch structure. Preferably, the patch body 10 has a consistent overall weaving structure, with uniform structural strength at all locations.

[0049] In one alternative embodiment, the weaving density at the periphery of the shoulder joint PET patch is lower than that in the central region. The lower weaving density at the periphery results in a higher porosity of the patch body 10, facilitating threading. Furthermore, a growth-promoting material is added to the patch body 10 to enhance the adsorption effect.

[0050] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
