Description

Technical Field

[0001] This utility model relates to the packaging of medical sutures, and more specifically, to a medical suture winding reel. Background Technology

[0002] Medical sutures are common bio-textiles used in human surgery for suturing wounds, connecting tissues, and ligating blood vessels. They consist of rigid needles and flexible threads. Currently, medical sutures are typically packaged in simple cardboard boxes. For example, the "Intermediate Distribution Suture Box" disclosed in Chinese Patent Publication No. CN1134270A (publication date October 30, 1996) is an example. However, this type of cardboard packaging is fragile and easily damaged, making it difficult to effectively secure and protect the sutures and needles. Furthermore, the number of needles and sutures included in the packaging is limited, resulting in significant material consumption when packaging a single type of suture.

[0003] To increase the number of sutures that can be packaged, Chinese Patent Publication No. CN101711698A discloses a "suture pouch" (publication date: May 26, 2010), which includes a suture storage component. The suture storage component includes an outer wall and an inner wall, the inner wall being radially spaced from the outer wall and defining a suture storage area between them. The inner wall defines a needle storage area and includes at least one opening to allow at least one suture to be received through the at least one opening. The outer wall includes a plurality of inwardly extending protrusions configured to engage with a lid. The suture pouch further includes a lid configured to be received within the outer wall of the suture storage component and selectively engages with the inwardly extending protrusions formed on the outer wall. The suture storage component is typically made of plastic, while the lid is made of paper. Paper lids are soft and easily deformed, providing poor fixation and protection for the sutures, and are prone to detaching from the winding groove, causing multiple sutures to become tangled and hindering suture retrieval. In addition, the aforementioned suture pack has a circular structure, which makes it inconvenient to hold and easy to slip out of your hand.

[0004] Given the aforementioned problems with the existing packaging structure of sutures, it is necessary to improve it to reduce damage to the sutures caused by packaging, facilitate on-site use, and reduce the consumption of packaging materials for single-specification suture needles and threads.

[0022] 3. Beneficial effects

[0023] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0024] (1) A medical suture winding reel of the present invention includes a base, a pressure cap and a cover plate. The base has an outer baffle and an inner baffle arranged in a circumferential direction. A suture storage area is formed between the outer baffle and the inner baffle. The base also has a needle mounting part located inside the inner baffle. The inner baffle also has an opening communicating with the suture storage area and the inner space of the inner baffle. The pressure cap is detachably installed on the base to cover the suture storage area and to place the needle mounting part inside the cavity. The cover plate is detachably installed on the pressure cap to cover the needle mounting part. With the above design, a ring-shaped pressure cap is added to the base. The pressure cap protects and restricts the sutures in the suture storage area to reduce suture damage and prevent the sutures from detaching from the constraint of the suture storage area and causing multiple sutures to become entangled. This facilitates the packaging and quick access of multiple sutures.

[0025] (2) A medical suture winding reel of the present invention has two or more needle mounting slots in its needle mounting part, which increases the number of sutures packaged and can stabilize and fix the needles and arrange them in an orderly manner.

[0026] (3) A medical suture winding reel of the present invention has an outer cover edge and an inner cover edge arranged in a circumferential direction on its cover. The outer cover edge is fastened to the outer side of the outer baffle, and the inner cover edge is fastened to the inner side of the inner baffle.

[0045] 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 and embodiments.

[0046] [Example]

[0047] Combination Figure 1 and Figure 2 As shown, a medical suture winding reel of this embodiment includes a base 1, a pressure cap 2, and a cover plate 3, wherein:

[0048] The base 1 has an outer baffle 1-1 and an inner baffle 1-2 arranged circumferentially, forming a suture storage area 1-3 between the outer baffle 1-1 and the inner baffle 1-2. The thread portion of the suture is wound around the suture storage area 1-3. The base 1 also has a needle mounting part 1-4 located inside the inner baffle 1-2, and the needle of the suture is fixed on the needle mounting part 1-4. The inner baffle 1-2 also has an opening 1-5 connecting the suture storage area 1-3 and the inner space of the inner baffle 1-2, so that the thread portion connected to the needle in the suture storage area 1-3 can be introduced into the middle area of ​​the base 1 through the opening 1-5. When winding the suture, the needle can be fixed to the needle mounting part 1-4 first, and then the thread portion can be introduced through the opening 1-5 and wound around the suture storage area 1-3.

[0049] The pressure cap 2 is an annular structure with a cavity 2a in the middle, and the pressure cap 2 is detachably installed on the base 1 to cover the above-mentioned suture storage area 1-3, and to place the needle mounting part 1-4 inside the cavity 2a; that is, the pressure cap 2 is a cover for the suture storage area 1-3, which is used to protect and restrict the sutures in the suture storage area 1-3, so that the suture can be stably kept inside; at the same time, the needle mounting part 1-4 is exposed through the cavity 2a, which facilitates the grasping of the needle, and the pressure cap does not need to be removed when the suture is taken out;

[0050] The cover plate 3 is detachably installed on the pressure cap 2 to cover the needle mounting parts 1-4. The function of the cover plate 3 is to cover the needles on the needle mounting parts 1-4 to prevent the needles from being exposed and causing punctures to the outer packaging.

[0051] Compared with existing suture reels, the medical suture reel in the suture storage area 1-3 of this embodiment has an added ring-shaped pressure cap 2 on the base 1. The pressure cap 2 protects and restricts the sutures in the suture storage area 1-3, thereby reducing suture damage and preventing the sutures from detaching from the constraint of the suture storage area 1-3 and causing multiple sutures to become entangled. This facilitates the packaging and quick access of multiple sutures.

[0052] like Figure 2 and Figure 3 As shown, correspondingly, the needle mounting part 1-4 has two or more needle slots 1-4a, which can fix the arc-shaped needle and play a role in stabilizing and orderly arranging the needle. Figure 3 The needle mounting part 1-4 shown has 10 needle slots 1-4a, each of which can be numbered to increase the number of threads that can be packaged. The height of the needle mounting part 1-4 is preferably the same as or close to the height of the outer baffle 1-1 and inner baffle 1-2 of the base 1, which can avoid large deformation of the winding reel under pressure due to height differences. Preferably, the top of the needle mounting part 1-4 is flush with the upper surface of the pressure cap 2 mounted on the base 1, so that the needle mounting part 1-4 can provide some support to the middle of the cover plate 3, preventing the cover plate 3 from being deformed inwards after being squeezed.

[0053] Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the pressure cap 2 has an outer cover edge 2-1 and an inner cover edge 2-2 arranged circumferentially. The outer cover edge 2-1 is fastened to the outside of the outer baffle 1-1, and the inner cover edge 2-2 is fastened to the inside of the inner baffle 1-2. That is, the outer cover edge 2-1 and the inner cover edge 2-2 of the pressure cap 2 will not intrude into the inside of the suture storage area 1-3 during installation, which can prevent the sutures in the suture storage area 1-3 from being squeezed and damaged during the closing process of the pressure cap 2, thus providing further protection for the sutures and preventing the sutures from being clamped and causing difficulty in thread retrieval. Furthermore, the outer cover edge 2-1 and the outer baffle 1-1, and the inner cover edge 2-2 and the inner baffle 1-2 are all connected by a snap-fit ​​structure. The snap-fit ​​structure on the inner and outer sides can make the pressure cap 2 firmly and reliably closed and not easy to loosen. Specifically, refer to Figures 2 to 4 As shown, the outer baffle 1-1 has several outer snap-fit ​​protrusions 1-1a distributed around its outer periphery, and the inner side of the outer cover edge 2-1 has several outer snap-fit ​​grooves 2-1a that can engage with the outer snap-fit ​​protrusions 1-1a. The inner side of the inner baffle 1-2 has several inner snap-fit ​​protrusions 1-2a distributed around its inner periphery, and the outer side of the inner cover edge 2-2 has several inner snap-fit ​​grooves 2-2a that can engage with the inner snap-fit ​​protrusions 1-2a. The outer snap-fit ​​protrusions 1-1a and the outer snap-fit ​​grooves 2-1a form the outer snap-fit ​​structure, and the inner snap-fit ​​protrusions 1-2a and the inner snap-fit ​​grooves 2-2a form the inner snap-fit ​​structure.

[0054] catch Figure 2 , Figures 4 to 6 As shown, in this embodiment, the pressure cap 2 is also provided with a notch 2b communicating with the cavity 2a. When the pressure cap 2 is installed on the base 1, the notch 2b is positioned opposite to the openings 1-5 on the base 1. This creates a thread extraction notch in the thread storage area 1-3. When retrieving the thread, after removing the needle, the thread can be pulled out from the notch, reducing thread bending during extraction and making the thread extraction operation more flexible and convenient. To prevent misalignment during the assembly of the pressure cap 2 and the base 1, a foolproof positioning structure is provided between the pressure cap 2 and the base 1. This foolproof positioning structure can position the assembly of the pressure cap 2 and the base 1, preventing misalignment between the notch 2b on the pressure cap 2 and the openings 1-5 on the base 1, thus improving the convenience and accuracy of the winding reel assembly. Specifically, the foolproof positioning structure includes a positioning hole 1-6 on the base 1 and a positioning pin 2-3 on the cover 2. When the cover 2 is installed with the base 1, the positioning pin 2-3 is inserted into the positioning hole 1-6 to prevent incorrect assembly position.

[0055] return Figures 2 to 6In this embodiment, the base 1 has several lower vent holes 1-7 communicating with the suture storage area 1-3, and the pressure cap 2 has several upper vent holes 2-4 communicating with the suture storage area 1-3. The lower vent holes 1-7 and the upper vent holes 2-4 enable gas convection within the cavity of the suture storage area 1-3, facilitating the flow of ethylene oxide gas within the winding reel during EO sterilization, ensuring sufficient contact with the suture for sterilization and guaranteeing sterilization reliability. The upper end face of the pressure cap 2 also has at least two lugs 2-5 for engaging and fixing the cover plate 3, facilitating the fixing and disassembly of the cover plate 3 on the pressure cap 2. The cover plate 3 is also provided with an observation window 3-1 opposite to the label affixing part 1-8 on the inner side of the base 1, allowing product identification information to be affixed to the label affixing part 1-8, and enabling direct observation of product specifications and other information through the observation window 3-1. In this embodiment, both the base 1 and the cover 2 can be injection molded from plastic material. The base 1 also has several process holes 1-9, and the cover plate 3 can be made of paper material.

[0056] As a preferred embodiment, the medical suture winding reel of this embodiment has a polygonal outer contour, that is, at least the base 1 and the pressure cap 2 adopt a polygonal design. Compared with the common circular winding reel, the polygonal winding reel is easier to grip and less likely to slip from the hand during use. For example Figures 1 to 6 The diagram illustrates a preferred outer contour shape for a regular hexagon. Besides a regular hexagonal outer contour, other shapes include, but are not limited to, pentagons, heptagons, and octagons, for example... Figure 7 The image shows a regular pentagonal medical suture winding reel. Figure 8 and Figure 9 The image shows a regular octagonal medical suture winding tray. When using a polygonal outer contour design, the lugs 2-5 on the cap 2 can be designed at the angle between two adjacent sides, and the outer side of the angle is preferably designed with rounded corners to avoid the angle being too sharp and causing injury.

[0057] In this embodiment, a medical suture winding reel allows for the following process: First, the needle portion of the suture is fixed to the needle mounting portion 1-4 of the base 1. Then, the suture portion is wound through the opening 1-5 into the suture storage area 1-3. After all the sutures are wound, the pressure cap 2 is placed on the base 1 to protect and confine the suture within the storage area 1-3. Next, a cover plate 3 is installed on the pressure cap 2. For retrieval, the cover plate 3 is first removed, then the corresponding needle is taken out from the needle mounting portion 1-4, and the corresponding suture portion is pulled out from the suture storage area 1-3.

[0058] This embodiment of a medical suture winding reel adds a ring-shaped pressure cap to the base. The pressure cap protects and restricts the sutures in the suture storage area, thereby reducing suture damage and preventing the sutures from detaching from the constraint of the suture storage area and causing multiple sutures to become entangled. This facilitates the packaging and quick access of multiple sutures and also has the advantages of simple overall structural design, good air flow, and easy EO sterilization.

[0059] 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.
