Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an adaptive medical traction sleeve for shoulder arthroscopy and its weaving method. Background Technology

[0002] Shoulder arthroscopy, an important branch of minimally invasive orthopedic surgery, requires the stable suspension and traction of the patient's upper limb during the procedure to create ample surgical visibility and operating space. The performance of the limb fixation and traction components directly affects the success of the surgery and the patient's safety.

[0003] Currently, the mainstream limb fixation and traction methods in shoulder joint surgery in clinical practice generally involve wrapping the limb with a traction strap made of woven or woven fabric, and then supplementing it with multiple layers of bandages for fixation. For example, in existing technologies, conventional square traction straps are designed with irregular trapezoidal shapes to improve the wrapping shape. These methods, in essence, still do not depart from the traditional paradigm of "fabric wrapping + bandage fixation".

[0004] However, this traditional fixation method has a series of inherent technical defects, which have become a bottleneck restricting the efficiency and safety of the surgery: The procedure is cumbersome, time-consuming, and labor-intensive: It relies on medical staff to manually wrap the bandage for fixation, which is a lengthy process. This not only prolongs the preoperative preparation time, but also makes it difficult to precisely control and maintain the tightness of the wrapping, relying too much on the operator's experience.

[0005] The dense woven fabric completely covers the limb, obscuring the skin surface and hindering intraoperative monitoring, posing a safety hazard. This prevents medical staff from directly and immediately observing the skin color, swelling, and capillary refill of the distal limb during surgery, thus hindering effective monitoring of limb blood supply. Furthermore, any vascular or nerve compression caused by traction or positioning is difficult to detect and address promptly, constituting a clear safety risk.

[0006] Poor breathability and low patient comfort: Traditional traction belt materials have poor breathability. During surgery that lasts for several hours, the skin of the wrapped limb cannot effectively dissipate heat and moisture, which can easily cause discomfort such as stuffiness and dampness, and may even lead to skin maceration or pressure injury, seriously affecting the patient's experience.

[0007] Insufficient fit and adaptability: Woven fabrics generally lack good elasticity, making it difficult to adapt to the circumference and shape changes of different patients' upper limbs from the upper arm to the forearm. The simple trapezoidal design does not fundamentally solve the fit problem and can still easily lead to local pressure concentration or insecure fixation, affecting the stability and effectiveness of traction.

[0008] Therefore, there is an urgent need in this field for a novel traction and fixation device for shoulder joint surgery that can overcome the aforementioned shortcomings. An ideal technical solution should enable rapid and convenient donning and fixation, provide excellent breathability to ensure patient comfort, allow unobstructed observation of limb blood circulation during surgery, and intelligently adapt to changes in limb shape to achieve stable and uniform fixation and traction. Summary of the Invention

[0009] This invention proposes an adaptive medical traction sleeve for shoulder arthroscopy and its weaving method to solve the problems of insufficient fixation and fit; low operation efficiency; safety hazards in intraoperative monitoring; and poor patient comfort.

[0010] The core technical solution of this invention is as follows: through the partitioned mesh structure, adaptive fit to the shape of the upper limb is achieved; through the mechanical gradient, while ensuring overall fixation, local pressure or loosening caused by traditional homogeneous fabric is avoided; the integrated functional back support structure creates a stable, comfortable and ergonomic traction force bearing and transmission base point, so that the traction force is evenly distributed through the entire back support part, improving traction stability and patient comfort.

[0011] The specific solution of the present invention is as follows: A method for knitting an adaptive medical traction cuff for shoulder arthroscopy, using a double-needle bed computerized flat knitting machine and employing full-form knitting technology to knit in one piece, including a connected mesh tube and a back support patch; the method includes the following steps: S1 braided mesh tube: Using at least one set of first yarns, cylindrical knitting is performed on the front and rear needle beds of the double-needle bed computerized flat knitting machine; Along the axial direction of the mesh section, at least a first mesh area and a second mesh area are woven in sections, wherein the mesh size of the first mesh area is larger than the mesh size of the second mesh area, the first mesh area corresponds to the upper arm area when worn, and the second mesh area corresponds to the forearm area when worn; S2 braided back hand support plate: Using at least two sets of yarns, including a second yarn and a third yarn, the weaving continues at the end of the mesh tube to form a multi-layered composite thick fabric; The multi-layer composite thick fabric includes an upper surface layer and a lower surface layer woven from upper and lower needle beds, respectively, and an intermediate layer formed between the upper surface layer and the lower surface layer; S3 performs post-processing on the woven one-piece fabric to form the final sleeve product.

[0012] Furthermore, the S1 braided mesh tube includes: First, the inner layer of the mesh tube is woven, and the weaving sequence along the axial direction is as follows: second mesh area, first mesh area, and first transition area; The outer layer of the mesh tube is then woven together, and the weaving sequence along the axial direction is as follows: first mesh area, second mesh area, second transition area; After weaving, the inner layer is folded inward to overlap with the outer layer, and then sewn together to form the mesh tube with a double-layer structure.

[0013] Furthermore, the S2 woven back-of-hand support sheet includes: The intermediate layer is formed by weft insertion; During the weaving of the upper and lower layers, the third yarn is introduced as a weft yarn and sandwiched between the upper and lower layers.

[0014] Furthermore, the process includes using yarn changing and loop exchange techniques during the weaving of the upper and lower layers to fix the weft yarn; The upper and lower layers are woven to form a pattern, and the loops of the front and back needle beds are exchanged at the edge of the pattern, while the second yarn is fed in to lock the weft yarn.

[0015] Furthermore, the S2 woven back-of-hand support sheet includes: The intermediate layer is formed by connecting loops; The third yarn serves as a spacer yarn, and is formed alternately in a loop structure on the corresponding loops of the upper and lower surfaces, thereby connecting the upper and lower surfaces.

[0016] Furthermore, the S2 woven back-of-hand support sheet includes: The back of the hand support plate is formed into an arched surface by using a row-differentiated weaving process. In the same weaving cycle, the number of rows woven in the upper surface layer is greater than the number of rows woven in the lower surface layer.

[0017] Furthermore, the S2 woven back-of-hand support sheet includes: The shaping knitting process employs a decrease-increase stitch technique. On both sides of the width direction, increase stitches first, then perform flat slewing, and finally decrease stitches to form a fabric shape that matches the contour of the back of the hand.

[0018] An adaptive medical traction cuff for shoulder arthroscopy, which is a one-piece knitted product, includes: A mesh tube, having an elastic tubular knitted structure, is used to wrap and fix the upper limb; it includes a first mesh area and a second mesh area, wherein the mesh size of the first mesh area is larger than the mesh size of the second mesh area; the mesh tube includes an inner layer and an outer layer formed integrally by knitting, the inner layer being folded inward and overlapped and fixed with the outer layer, thereby forming a sleeve with a double-layer structure; The back support plate, connected to one end of the forearm coverage area, is made of multi-layered composite thick fabric and is used to support and fix the hand.

[0019] Furthermore, the back-of-hand support shield includes: upper and lower surfaces, and An intermediate layer connecting the upper surface layer and the lower surface layer; The intermediate layer is composed of weft yarn or tuck yarn, which makes the back-of-hand support piece form a spacer fabric or quilted interlayer fabric structure.

[0020] Furthermore, the upper surface layer is formed into an arched surface that bulges towards the back of the hand through a row-differentiated knitting process; within a unit knitting cycle, the number of rows constituting the upper surface layer is greater than the number of rows constituting the lower surface layer.

[0021] The present invention has the following technical effects: 1. Adaptive fixed effect Traditional homogeneous fabrics cannot adapt to changes in limb shape. This invention, through a gradient mesh design, allows the sleeve to adapt to the differences in circumference and shape of the upper limb from the upper arm to the forearm among different patients. This "adaptive" fit ensures stable and uniform fixation without localized pressure concentration.

[0022] 2. Stable, controllable, and biomechanically compliant traction This invention constructs a stable and reliable traction force bearing and transmission system through an integrated, thick, woven back-of-hand support (using a quilted interlayer or spaced fabric structure) and a pre-set transverse traction strap. Combined with the snap-fit ​​adjustment to create a functional hand position, the traction force direction is controllable and evenly transmitted, conforming to upper limb biomechanics.

[0023] 3. Improved ease of operation Traditional methods rely on medical staff to manually wrap multiple layers of bandages, a tedious, time-consuming process with difficulty in precisely controlling tightness. This invention, through a one-piece molded sleeve structure and a snap-on quick-adjustment system, achieves "instant fixation," eliminating the wrapping step, greatly shortening preoperative preparation time, and reducing the problem of inconsistent tightness caused by differences in operator experience.

[0024] 4. Intraoperative safety monitoring capabilities Traditional dense fabrics completely obscure the limbs, hindering intraoperative observation. This invention's innovative all-knitted mesh structure, especially the zoned, visible mesh, provides medical staff with a direct, unobstructed window to observe the skin color, swelling, and blood circulation (vascularity) of the distal limb. This feature allows for the immediate detection and management of risks of vascular and nerve compression due to traction or positioning, improving the safety of the surgical procedure.

[0025] 5. Improve user experience and comfort Traditional wrapping methods are stuffy and poorly breathable. This invention utilizes the inherent high elasticity and breathability of the knitted coil structure, combined with a zoned mesh design, to create highly efficient airflow channels. This not only significantly improves breathability and heat dissipation, avoiding the discomfort of dampness and heat during prolonged surgery, but also, due to the soft, elastic, and conforming material, avoids rigid compression, providing patients with superior intraoperative comfort.

[0026] In summary, this invention overcomes the inherent defects of traditional technologies and, through systematic innovation, provides a safer, more efficient, more comfortable, and more economical traction fixation solution for shoulder arthroscopic surgery, which has significant clinical practical value and market prospects.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In this specification, identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions towards or away from a specific component, respectively. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "multiple" means two or more.

[0031] This invention provides an adaptive medical traction cuff for shoulder arthroscopy and its preparation method. The traction cuff, which adapts to the shape of the human arm, is fabricated using a fully formed molding technique. The cuff comprises two parts: a mesh tube 1 and a back-of-hand support plate 2. The former primarily serves to fix the upper limb, while the latter supports the hand and forms the gripping traction point. The attachments are then fixed to the support plate through a simple sewing process. During use, the patient puts on the cuff and fixes their fingers to the back-of-hand support plate 2. Then, the longitudinal adjustment component 4 is fixed forward, causing the metacarpophalangeal joint to flex, forming a stable gripping posture. The lateral adjustment component 3 is then lifted and fixed, completing the traction. This method reduces the need for bandage fixation and wrapping, making preoperative fixation and traction of the upper limb more convenient and faster. It also minimizes limb obstruction and maintains wearing comfort, facilitating observation of limb blood circulation during surgery and ensuring a smooth surgical procedure.

[0032] Example 1 This invention provides a method for preparing an adaptive medical traction sleeve for shoulder arthroscopy. The mesh tube 1 is designed with different mesh structures in different areas to achieve different deformation capabilities and elasticity. It can be woven into a round tube using a single yarn feeder. The back support sleeve 2 is prepared using a needle feeding process. It requires three yarn feeders to feed yarn to achieve thick fabric weaving, providing better support and serving as the starting point for traction.

[0033] Specifically, the weaving stage includes: Braided mesh tube 1 Equipment selection: The sleeves can be knitted by a 14-18 double needle bed computer flat knitting machine with 1-1-2 needles. The double needle bed computer flat knitting machine includes a front needle bed and a back needle bed, and the front and back needle beds are knitted synchronously (flat knitting).

[0034] Material selection: The yarn is woven with wear-resistant, high-strength, and antibacterial yarns, using non-elastic or low-elastic synthetic fibers such as nylon and polyester. The fiber thickness ranges from 300D to 600D.

[0035] Specifically, such as Figures 1 to 3 As shown, three sets of yarns (A, B, and C) are used. First, the mesh tube 1 fabric is knitted, followed by the quilted interlayer fabric. Specifically, either yarn A or B is selected to knit the mesh structure. The first mesh area h1 has a large mesh pattern (rows × columns) of 3×3-5×5, providing greater deformation space to accommodate a larger diameter upper arm. The second mesh area h2 has small mesh patterns of 1×1-2×2, conforming to the forearm. h3 is the transition layer. The total number of stitches cast on for the mesh is x. Flat knitting (same needle bed for front and back) is used. First, the inner layer H1 is knitted in the order h2-h1-h3, then the outer layer H2 is knitted in the order h1-h2-h3, completing the mesh tube 1.

[0036] The weave of the back support plate 2 Weaving Design: The back-of-hand support panel 2 has a three-layer structure, including an upper layer, a lower layer, and a middle layer. The upper layer is woven with yarns from groups A and B, while yarn C, a bulky yarn, is inserted into the middle layer as a weft insert. The upper layer should be woven with comfortable, breathable, abrasion-resistant, and antibacterial yarns, such as cotton, viscose, or elastic yarns, with a yarn fineness of 36-43 tex. The middle layer yarns are bulky yarns, polyester monofilaments, nylon monofilaments, etc., with a monofilament diameter of 0.16-0.20 mm. Yarn A is in the front, and yarn B is in the back. The upper layer yarns are interchanged at the edge of the diamond pattern, and the yarn B on the back replaces the yarn A on the front. The loops of the front and back needle beds are interchanged to fix the yarn C and improve the stability of the fabric structure. The diamond pattern of the upper layer has a 7*7 repeat. After the upper layer is woven, the weft insert yarn is inserted.

[0037] Forming process: Configure y as the total number of rows, x as the total number of stitches, and x1~x4 as the number of stitches increased or decreased on one side. The specific forming and knitting process is as follows: The same pattern of increasing stitches → flat rolling → decreasing stitches is used on both the left and right sides. Taking the left side as an example, the increasing stitch process is carried out first, using an uneven increasing stitch method, that is, increasing stitches quickly first and then slowly, i.e., y1-x1 (representing the number of stitches increased x1 in row y1), then y2-x2, followed by flat rolling in row y3. During the flat rolling stage, no increase or decrease is made in row y3. Then the decreasing stitch process is carried out, using a slow decreasing followed by a fast decreasing method, first y4-x3 and then y5-x4. The same pattern is used on the right side to achieve symmetrical shaping and complete the knitting.

[0038] Post-processing and assembly of the sleeve: Fold the inner H1 part of the mesh tube 1 inward and sew it to the last end of the h2 part of the outer H2; sew the transverse bandage of the back support plate 2 across the proximal interphalangeal joints and metacarpophalangeal joints on both sides, serving as a traction and lifting point while also fixing the palm; sew the longitudinal bandage in the middle of the reverse side of the back support plate 2, and sew the buckle to the wrist, ensuring that the buckle and the longitudinal bandage are in a straight line after wearing. Insert the male buckle of the longitudinal bandage into the female buckle at the wrist to complete the bending and fixing of the palm. The palm is passively bent to form a grasping posture, which can be pulled and lifted. The elastic band can adapt to the palm length of different people. Sew Velcro to the wrist for adjusting the tightness; finally, the edges of the back support plate 2 can be bound. The finished product design is shown in the figure. Figure 4 Furthermore, the width of the transverse bandage is 2.5-3.5cm. The transverse bandage on the inner side of the palm can place and fix the thumb and palm, while the length on the outer side is about 80-120cm. Furthermore, the length of the longitudinal bandage is 45-65cm, including the bandage and the elastic band. The bandage part needs to be sewn into the middle of the back support plate 2 of the hand, from the bottom to the top, to provide support.

[0039] Example 2: In this embodiment, the weaving of the mesh tube 1 is the same as in Example 1, the difference being that the back-of-hand support piece 2 is woven with a different structure. The "quilted interlayer fabric" of Example 1 is changed to "spaced fabric", and a weaving process with differentiated row counts is introduced to achieve better structural support and fit to the hand shape.

[0040] Specifically, C, acting as a spacer yarn, is suspended from the reverse side of the upper and lower surface layer loops using a tucked loop method, serving as an intermediate layer to provide support and stabilize the structure. The tucked loop spacing between the same needle bed is 8 stitches, resulting in a fabric of moderate thickness. Furthermore, to make the hand back support piece 2 fit the hand shape better, the number of rows in the upper and lower surface layers is differentiated within a single knitting cycle. Specifically, the upper surface layer has more knitted rows than the lower surface layer within one knitting cycle; for example, the former could have 3 rows and the latter 1. This difference in row count causes the fabric to bulge forward, forming a subtle arch that better conforms to the limb. The forming process and post-processing are the same as in Example 1: a lead-in / lead-out needle model is established, followed by weaving and final processing.

[0041] Example 3 This invention provides an adaptive medical traction cuff for shoulder arthroscopy, which is a one-piece knitted product comprising an adaptive mesh tube 1 and a back-of-hand support patch 2, wherein the back-of-hand support patch 2 is formed by a take-up and release needle process, wherein: The adaptive mesh tube 1 has an elastic tubular knitted structure for wrapping and fixing the upper limb; the mesh tube 1 includes at least a first mesh area for the upper arm covering area and a second mesh area for the forearm covering area along its axial direction; the knitted structure of the upper arm covering area is the first mesh structure, and the knitted structure of the forearm covering area is the second mesh structure, and the mesh size of the first mesh structure is larger than the mesh size of the second mesh structure; the back of the hand support plate 2 is connected to one end of the forearm covering area of ​​the mesh tube 1, and is a thick knitted area with a three-dimensional structure for supporting and fixing the hand.

[0042] Specifically, the mesh tube 1 includes an inner layer and an outer layer formed integrally by weaving. The inner layer is folded inward and overlapped and fixed with the outer layer, thereby forming a sleeve with a double-layer structure. In order to accommodate the different arm circumferences and required elastic deformation of the upper arm and forearm, the mesh loop size of the first mesh structure in the upper arm covering area is 3×3 to 5×5, and the mesh loop size of the second mesh structure in the forearm covering area is 1×1 to 2×2.

[0043] The back-of-the-hand support piece 2 is a multi-layer composite knitted structure, including an upper surface layer and a lower surface layer, and an intermediate layer connecting the upper surface layer and the lower surface layer; wherein, the intermediate layer is composed of weft yarn or tuck yarn, so that the back-of-the-hand support part forms an interlayered fabric or quilted interlayered fabric structure. When the intermediate layer is composed of tuck yarn, the spacing between adjacent tuck connection points on the same needle bed is 6 to 10 stitch lengths. An arched curved surface convex towards the back of the hand is formed by a row-differentiated knitting process; specifically, in a unit knitting cycle, the number of rows constituting the upper surface layer is greater than the number of rows constituting the lower surface layer, and further, the ratio of the number of rows of the upper surface layer to the lower surface layer is (2-4):1. The back of the hand support plate 2 also includes a lateral adjustment component 3 and a longitudinal adjustment component 4. The lateral adjustment component 3 is fixedly installed on the back of the hand support plate 2 and spans across the corresponding positions of the proximal interphalangeal joint and metacarpophalangeal joint. The longitudinal adjustment component 4 includes a lateral bandage sewn to the palm side of the back of the hand support plate 2 and a fastener installed at the corresponding position on the wrist.

[0044] In terms of material selection, the mesh tube 1 is woven with abrasion-resistant, high-strength yarn with a fineness of 300D to 600D, such as non-elastic or low-elasticity chemical fibers, such as nylon and polyester; the upper and lower layers of the back support plate 2 are woven with yarn with a fineness of 36tex to 43tex, such as comfortable, breathable, abrasion-resistant, and antibacterial cotton, viscose, and elastic yarn; the middle layer is made of bulky yarn with a fineness of 400D to 800D or monofilament with a diameter of 0.16mm to 0.20mm, such as polyester monofilament and nylon monofilament.

[0045] In summary, the weaving of the sleeve of this invention mainly consists of a mesh tube 1 and a back-of-hand support plate 2. The mesh tube 1 adopts a zoned design, with mesh openings of different deformation capabilities in different parts to achieve adaptive wrapping and fixation of the limb. The back-of-hand support plate 2 uses a knitted quilted interlayer or spaced structure of a certain thickness, and is woven into the shape of the hand using a forming process to fix and support the hand. Finally, the sleeve is sewn with accessories to complete the preparation of the traction glove. This sleeve is not only convenient to wear, saving preoperative time, but also does not compress the limb, facilitates observation of limb blood circulation, and is comfortable and breathable.
