Description

Technical Field

[0001] This utility model relates to the field of medical device packaging, and more specifically, to a suture needle holder structure and a medical suture winding reel. Background Technology

[0002] Medical sutures are common bio-textiles used in human surgery to suture wounds, connect tissues, and ligate blood vessels. They consist of rigid needles and flexible threads. Medical sutures are typically stored in sterile packs, which are opened and used on-site during surgery. However, prolonged storage in sterile packs can cause sutures to bend and knot, making them difficult to remove and potentially damaging the barbs on the suture.

[0003] Currently, medical suture packaging mainly uses two types of packaging: paper wrapping boards and plastic wrapping trays. Paper wrapping boards mostly use the figure-eight wrapping method, where the suture is wrapped in a figure-eight shape and fixed to the cardboard. The needle and suture are packaged in layers of cardboard. When retrieving the suture, it is pulled out, which makes it easy to straighten the suture before surgery. However, because the cardboard is relatively soft, it can easily damage the suture when subjected to external pressure. Plastic wrapping trays mostly use the O-shaped wrapping method, where the suture is wrapped in a plastic tray and the needle is fixed to the tray. Because the plastic tray is stronger, it can also protect the suture when subjected to external pressure.

[0004] Chinese Patent Publication No. CN201389047Y discloses a "medical suture packaging box," which has a rigid tray-type box body composed of an upper shell and a lower shell. The upper shell has intermittent arc-shaped inner and outer edge pressure strips. The upper and lower shells are fastened together, and an 8-shaped groove is formed between the inner and outer edge pressure strips. Several suture mounting and positioning holes are respectively provided along the 8-shaped groove on the upper and lower shells. This medical suture packaging box combines the advantages of paper winding board and plastic winding tray, allowing the suture to be pulled out smoothly and without tangling.

[0005] Chinese Patent Publication No. CN205094527U discloses "An inner packaging for holding multiple medical suture needles with sutures." The packaging material is medical-grade polypropylene. Each suture is orderly wrapped and fixed around the inner frame, with multiple pressure caps on the top of each frame to prevent the suture from slipping out. Each suture needle has a specific locking point to ensure the orderly arrangement of sutures and needles. This inner packaging for suture needles with sutures uses a multi-piece design, allowing for multiple extractions of needles and sutures during surgery, thus mitigating surgical delays to some extent.

[0006] Similar existing technologies include: "Packaging for Sutures and Needles" disclosed in Chinese Patent Publication No. CN 109928086 A, and "A Medical Suture Needle Winding Reel" disclosed in Chinese Patent Publication No. CN215534693U. Both employ a rigid winding tray structure to achieve suture winding and needle fixation. However, in existing technologies, needle fixation generally employs two methods: sponge body and clamping posts. The former involves inserting the needle into the sponge body for fixation, but the needle removal operation is relatively cumbersome. The latter uses three or four clamping posts to hold and fix the needle, offering the advantage of convenient needle removal, but the needle is prone to popping out and falling out within the clamping posts, leading to problems such as suture tangling and knotting. Summary of the Invention

[0007] 1. Technical problem to be solved by the utility model

[0008] The purpose of this utility model is to overcome the above-mentioned shortcomings of the existing technology and provide a suture needle clamping structure and a medical suture winding reel. The suture needle clamping structure of this utility model adopts a three-column design to achieve orderly clamping and fixing of the arc-shaped suture needle. A hollow cavity is provided at the lower part of the corresponding clamping column, allowing the lower part of the clamping column to have space for elastic deformation towards the opposite side of the clamping groove. This allows the suture needle to be elastically clamped, and the clamping column is deformed by the pressure of the suture needle to form a clamping groove that is smaller at the top and larger at the bottom. This not only improves the firmness of the suture needle clamping but also prevents the suture needle from popping out and falling off. In addition, the medical suture winding reel adopts a racetrack-style winding groove design, which is simple in structure and convenient in manufacturing process. It can greatly reduce damage to medical sutures and the bending or knotting of sutures during storage, while also facilitating on-site retrieval of medical sutures.

[0050] 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.

[0051] This utility model relates to a suture needle holder structure and a medical suture winding reel, designed to prevent sutures from bending or knotting during storage, reducing suture damage and facilitating on-site retrieval. Specifically, it combines... Figure 3 and Figure 4 As shown, the sewing needle clamping structure of this utility model includes two first clamping posts 1-2-1a located on the same side and a second clamping post 1-2-2a disposed between the two first clamping posts 1-2-1a and opposite to the two first clamping posts 1-2-1a. A clamping groove 1-2-3 is provided between the second clamping post 1-2-2a and the two first clamping posts 1-2-1a. The two first clamping posts 1-2-1a and the second clamping post 1-2-2a constitute a three-post clamping needle structure. Since the second clamping post 1-2-2a is located in the middle of the two first clamping posts 1-2-1a, the two first clamping posts 1-2-1a can clamp the outer arc of the needle 3-2, and the second clamping post 1-2-2a can clamp the inner arc of the needle 3-2. This limits the direction in which the inner arc of the needle 3-2 always faces the second clamping post 1-2-2a during installation (that is, the inner arc of the needle 3-2 faces the direction of the single post), thus achieving orderly clamping and fixing of the arc-shaped needle. The lower part of the first clamping post 1-2-1a and / or the lower part of the second clamping post 1-2-2a is provided with a hollow cavity 1-2-2b, so that the lower part of the first clamping post 1-2-1a and / or the lower part of the second clamping post 1-2-2a has space for elastic deformation to the opposite side of the clamping groove 1-2-3. In other words, the lower part of either the first clamping post 1-2-1a or the second clamping post 1-2-2a can be designed as an elastic deformation structure, or both the lower parts of the first clamping post 1-2-1a and the second clamping post 1-2-2a can be designed as elastic deformation structures. Since the clamping post is elastic, it can elastically clamp the suture needle 3-2. Moreover, after the suture needle 3-2 is installed, the clamping post is deformed by the compression of the suture needle 3-2 to form a clamping groove 1-2-3 in a "smaller at the top and larger at the bottom" state, which not only improves the clamping firmness of the suture needle 3-2, but also avoids the problem of the suture needle 3-2 popping out and falling off. It can be used to fix the suture needle in various medical suture winding trays.

[0052] Furthermore, such as Figure 3 and Figure 4As shown, the upper part of the first clamping post 1-2-1a and / or the upper part of the second clamping post 1-2-2a are further provided with a limiting boss 1-2-1b extending into the clamping groove 1-2-3. That is, one or both of the first clamping post 1-2-1a and the second clamping post 1-2-2a have a limiting boss 1-2-1b. This limiting boss 1-2-1b can further restrict the needle 3-2 and further prevent the needle from popping out. In addition, the upper part of the first clamping post 1-2-1a and / or the upper part of the second clamping post 1-2-2a are also provided with a chamfer, which can facilitate the guidance of the needle 3-2 during installation, making the installation operation of the needle 3-2 simpler and more convenient.

[0053] In a specific implementation, preferably, the limiting boss 1-2-1b is located on the upper part of the first clamping post 1-2-1a, and a first chamfer 1-2-1c is provided at the upper end of the limiting boss 1-2-1b; the hollow cavity 1-2-2b is located on the lower part of the second clamping post 1-2-2a, and the second clamping post 1-2-2a is inverted "L" shape, with a second chamfer 1-2-2c at the upper end; the first chamfer 1-2-1c and the second chamfer 1-2-2c form a trumpet-shaped insertion entrance located on the upper part of the clamping groove 1-2-3. Using the above specific structure, the structure is simple and easy to manufacture, and the trumpet-shaped insertion entrance further facilitates the installation of the sewing needle. In addition, baffles 1-2-4 are provided on both sides of the bottom of the clamping groove 1-2-3. The baffles 1-2-4 serve to strengthen the needle clamping structure and support the needle, preventing the needle from contacting the bottom of the clamping groove and affecting the ease of use.

[0054] Combination Figure 1 , Figure 2 as well as Figure 5 and Figure 6 As shown, this utility model discloses a medical suture winding reel, comprising a base 1 and a top cover 2. The base 1 has a disc-shaped structure, and the top cover 2 is detachably mounted on the base 1. A winding groove 1-1 is provided near the edge of the base 1. Several pin-locking assemblies 1-2 for fixing suture needles 3-2 and studs 1-3 for connecting the tail ring 3-3 of the suture 3-1 are respectively located inside the winding groove 1-1. The pin-locking assemblies 1-2 adopt the aforementioned suture needle locking structure. This medical suture winding reel adopts a racetrack-style winding groove design, which is simple in structure and convenient in manufacturing process. It can greatly reduce damage to medical sutures and the bending or knotting of sutures during storage, while also facilitating on-site retrieval of medical sutures. Figure 6The diagram illustrates a method of winding the medical suture 3 onto the substrate 1. The medical suture 3 mainly consists of a suture 3-1 and a needle 3-2 connected to one end of the suture 3-1. The end of the suture 3-1 away from the needle 3-2 has a tail loop 3-3. When installing the medical suture 3, the needle 3-2 is placed in the corresponding clamping groove 1-2-3 of the needle clamping assembly 1-2. The suture 3-1 is then wound around the winding groove 1-1. When the suture 3-1 is almost finished, it extends into the inner side through the gap in the winding groove 1-1. A suitable loop 1-3 is selected to hold the tail loop 3-3 of the suture 3-1. Finally, the top cover 2 is installed on the substrate 1.

[0055] The medical suture winding reel of this utility model will be further described below with reference to the embodiments.

[0056] [Example 1]

[0057] like Figures 1 to 6 As shown, a medical suture winding reel of this embodiment includes a base 1 and a top cover 2. The base 1 has a disc-shaped structure, such as a racetrack-shaped structure with semi-circular ends as shown in the figure. The top cover 2 is detachably mounted on the base 1. A winding groove 1-1 is provided on the base 1 near its edge. The winding trajectory of the winding groove 1-1 is similar to the outer contour shape of the base 1. Several pin-holding assemblies 1-2 for fixing suture needles 3-2 and studs 1-3 for connecting the tail ring 3-3 of the suture 3-1 are respectively provided on the inner side of the winding groove 1-1. The aforementioned pin-holding assemblies 1-2 are specifically as follows: Figure 3 and Figure 4The needle clamping structure shown includes two first clamping posts 1-2-1a located on the same side and a second clamping post 1-2-2a located between the two first clamping posts 1-2-1a and opposite to them. A clamping groove 1-2-3 is provided between the second clamping post 1-2-2a and the two first clamping posts 1-2-1a. The lower part of the second clamping post 1-2-2a has a hollow cavity 1-2-2b, allowing the lower part of the second clamping post 1-2-2a to elastically deform towards the opposite side of the clamping groove 1-2-3. Furthermore, the upper part of the first clamping post 1-2-1a also has a limiting boss 1-2-1b extending inward towards the clamping groove 1-2-3, which further restricts the needle 3-2 and prevents it from popping out. Both the upper parts of the first clamping post 1-2-1a and the upper parts of the second clamping post 1-2-2a are chamfered. Specifically, the upper end of the limiting boss 1-2-1b is provided with a first chamfer 1-2-1c, and the upper end of the second clamping post 1-2-2a is provided with a second chamfer 1-2-2c. The first chamfer 1-2-1c and the second chamfer 1-2-2c form a funnel-shaped insertion entrance located at the upper part of the clamping groove 1-2-3, which can further facilitate the installation of suture needles. The above-mentioned racetrack-type winding groove and three-post needle holder structure design is simple in structure and convenient in manufacturing process. It can greatly reduce damage to medical sutures and the bending or knotting of sutures during storage, while facilitating the on-site retrieval of medical sutures. In addition, baffles 1-2-4 are provided on both sides of the bottom of the clamping groove 1-2-3. The baffles 1-2-4 extend upward from the upper end of the base 1 to a certain height, which can strengthen the structural strength of the location of the needle assembly 1-2. The baffles 1-2-4 can also provide some support for the sewing needle 3-2, preventing the sewing needle 3-2 from sticking to the end face of the base 1 and affecting the ease of use.

[0058] The medical suture winding reel of this embodiment can be a single piece or a multi-piece design. A single medical suture winding reel can hold one or more medical sutures 3. In the multi-piece design, the needle clamping assembly 1-2 consists of several sequentially arranged positioning blocks. Adjacent positioning blocks form the aforementioned needle clamping structure. Two first clamping posts 1-2-1a are separated by a dividing groove 1-2-1d on the corresponding positioning block. Each positioning block can include two end blocks and several intermediate blocks. One end block has two first clamping posts 1-2-1a, and the other end block has one second clamping post 1-2-2a. One end of each intermediate block has one second clamping post 1-2-2a, and the other end has two first clamping posts 1-2-1a. Several intermediate blocks are arranged sequentially. The two end blocks are located at opposite ends of the needle clamping assembly 1-2 and cooperate with adjacent intermediate blocks. For ease of understanding, Figure 3 and Figure 4The diagram only shows the mating structure of one set of positioning blocks. Here, one positioning block is defined as the first positioning block 1-2-1, and the other positioning block is defined as the second positioning block 1-2-2. The first positioning block 1-2-1 and the second positioning block 1-2-2 have a partition groove 1-2-1d on the side adjacent to each other. Two first clamping posts 1-2-1a are formed on the first positioning block 1-2-1. The second positioning block 1-2-2 extends to form a second clamping post 1-2-2a on the side adjacent to the first positioning block 1-2-1. The lower end of the second clamping post 1-2-2a is in an elastic cantilever state. When installing the suture needle 3-2, it is introduced through the funnel-shaped inlet and deformed by the pressure of the second clamping post 1-2-2a, thus smoothly entering the clamping groove 1-2-3. Within the clamping groove 1-2-3, the suture needle 3-2 is prevented from popping out and falling off due to the combined effects of the deformation of the second clamping post 1-2-2a and the blocking effect of the limiting boss 1-2-1b. Additionally, as... Figure 2 , Figure 5 and Figure 6 As shown, a pin plate 1-4 formed by a U-shaped groove on the base 1 is also provided on one side of the pin assembly 1-2. The free end of the pin plate 1-4 is located on the side close to the pin assembly 1-2. By tilting the free end of the pin plate 1-4 upward, the connection between the thread 3-1 and the needle 3-2 can be lifted. When in use, you can insert your index finger under the pin plate 1-4 of the base 1, press the outer edge of the base 1 with your thumb, and push the index finger upward to make the base 1 bend slightly. At this time, the free end of the pin plate 1-4 will lift the needle 3-2, which makes it easier to clamp the needle 3-2.

[0059] like Figure 2 and Figure 5 As shown, in the aforementioned medical suture winding reel, the winding groove 1-1 is formed by a winding baffle 1-1a, a suture-holding protrusion 1-1b disposed on the upper side of the winding baffle 1-1a, and the edge of the base 1. The winding baffle 1-1a has two opposing straight baffles and two opposing arc baffles. The winding trajectory formed by the two straight baffles is connected and transitioned through the winding trajectory formed by the two arc baffles, allowing the suture to wind smoothly and reducing damage to the suture. A gap is left between the straight baffles and the arc baffles to facilitate the suture 3-1 to wind from the outside of the winding groove 1-1 through the gap to the inside, facilitating the fixation of the needle 3-2 and the tail ring 3-3. In this embodiment, two sets of needle-holding assemblies 1-2 can be provided, respectively disposed on the inner side of the two arc baffles, and the sleeve 1-3 is a cylinder distributed along the inner side of the two straight baffles.

[0060] catch Figure 1 and Figure 2As shown, in this embodiment, the upper cover 2 is also provided with a viewing window 2-1, which facilitates observation of the needle type and specification without opening the suture reel. The upper cover 2 is separately mounted on the base 1. At this time, the base 1 is provided with several mounting posts 1-8, and the upper cover 2 is provided with several mounting holes 2-2. The upper cover 2 is fixed to the base 1 by the mounting holes 2-2 and the mounting posts 1-8. Specifically, four mounting posts 1-8 and four mounting holes 2-2 can be provided. The limiting height of the mounting posts 1-8 is consistent with the height of the winding baffle 1-1a, the height of the needle clamping assembly 1-2, and the height of the sleeve 1-3. This allows the upper cover 2 to fit tightly against the upper end of the winding baffle 1-1a and the sleeve 1-3 after it is closed, ensuring that the medical suture 3 will not slip out during storage and providing support for the base 1 to prevent deformation of the medical suture winding reel when it is pressed. In addition, the substrate 1 also has a first process hole 1-5, a second process hole 1-7, and a first positioning hole 1-6. The first process hole 1-5 can be a circular hole located at the ejector plate 1-4, making the ejector plate 1-4 easier to deform under stress. The second process hole 1-7 can be an oblong hole located inside the winding groove 1-1, which can reduce material usage and achieve weight reduction. Furthermore, the first process hole 1-5 and the second process hole 1-7 can play a process positioning role during the winding process. The first positioning hole 1-6 can be a circular hole located in the middle of the substrate 1, and the upper cover 2 has a second positioning hole 2-3 located opposite to the first positioning hole 1-6. The above-mentioned hole design on the substrate 1 and the upper cover 2 can improve air flow and facilitate EO (ethylene oxide) sterilization treatment.

[0062] The medical suture winding reel of this embodiment has the same basic structure and working principle as that of Embodiment 1, except that:

[0063] This embodiment is a medical suture reel with an automatic winding function. For example... Figure 7 and Figure 8 As shown, the base 1 is also provided with positioning blocks 1-9 for automatic winding, which can be conveniently used with automatic winding equipment for automatic winding, facilitating automated production and improving production efficiency.

[0064] Compared to Embodiment 1, this embodiment omits one set of pin assembly 1-2 and adds four circumferentially distributed positioning blocks 1-9 at the location of the pin assembly 1-2. In practical use, the base 1 can be installed on the automatic winding equipment using the positioning blocks 1-9 to facilitate automatic winding.

[0065] [Example 3]

[0066] The medical suture winding reel of this embodiment has the same basic structure and working principle as that of Embodiment 1, except that:

[0067] like Figures 9 to 11 As shown, in this embodiment, the upper cover 2 is integrally connected to the base 1 via a flexible hinge 2-4. A first buckle 1-10 is provided on the side of the base 1 away from the flexible hinge 2-4, and a second buckle 2-5, cooperating with the first buckle 1-10, is provided on the side of the upper cover 2 away from the flexible hinge 2-4. The upper cover 2 can be flipped open or closed on the base 1, resulting in a simple structure and convenient use.

[0068] Furthermore, in this embodiment, the base 1 has a base retaining edge 1-11 at its edge, and the top cover 2 has a cover retaining edge 2-6 at its edge. After the top cover 2 is fastened to the base 1, the base retaining edge 1-11 and the cover retaining edge 2-6 can abut against each other, providing support on both sides, so that the first buckle 1-10 and the second buckle 2-5 can be fastened together more stably. A ring of ventilation holes 2-7 is also provided on the outer side of the base 1 and the top cover 2 to facilitate sterilization.

[0069] This utility model discloses a suture needle clamping structure and a medical suture winding reel. The suture needle clamping structure adopts a three-column design to achieve orderly clamping and fixing of arc-shaped suture needles. A hollow cavity is provided at the lower part of the corresponding clamping column, so that the lower part of the clamping column has space for elastic deformation to the opposite side of the clamping groove. This allows the suture needle to be elastically clamped. The clamping column is deformed by the pressure of the suture needle to form a clamping groove that is smaller at the top and larger at the bottom. This not only improves the clamping firmness of the suture needle, but also avoids the problem of the suture needle popping out and falling off. The medical suture winding reel adopts a racetrack-shaped winding groove design, which is simple in structure and convenient in manufacturing process. It can greatly reduce the damage to medical sutures and the bending or knotting of sutures during storage, while facilitating the on-site retrieval of medical sutures.

[0070] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
