Description

Technical Field

[0001] This utility model relates to the field of medical device packaging technology, and in particular to a sterilization packaging structure suitable for joint surgical instruments. Through an improved design combining a shaping plate and a shielding bag, it achieves multiple functions such as instrument fixation, sterilization protection, and model visualization. Background Technology

[0002] In the prior art, such as the prior art document CN203555975U (joint instrument protection device), it includes a receiving bag and a placement plate. The placement plate is used to place the instrument to be protected. The placement plate includes a locking loop, a body, and a tip protector. One end of the body is connected to the tip protector. The body and the locking loop are integrally formed with the tip protector. One end of the locking loop is fixedly connected to the body. The body is provided with a locking groove that matches the locking loop. The locking groove is located near the tip protector. The combination structure of the receiving bag and the placement plate with locking loop has the following drawbacks: 1. The locking loop method for fixing joint instruments causes the instrument tip to rub directly against the locking loop, thus contaminating or damaging the jaws of the delicate instruments; 2. The tip protector is an opaque, rigid structure that obscures the instrument's working end model markings; 3. It is inconvenient to use. In addition, the applicant has found in practice that traditional plastic sealing packaging is prone to contamination during sterilization and transportation when the instrument tip punctures the bag. Although attempts have been made to add a protective shell to the head, the existing solutions present a contradiction between protection and visibility. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sterilization packaging structure suitable for joint surgical instruments, which can: 1) ensure that the forceps handle is kept open during sterilization; 2) protect the instrument tip while keeping the model visible; and 3) meet the specifications for individual packaging sterilization.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a sterilization packaging structure suitable for axial surgical instruments is provided, including a shielding bag and a shaping plate. One side of the shielding bag is dialysis paper and the other side is a transparent plastic sealing film. The dialysis paper and the transparent plastic sealing film are heat-sealed on three sides to form a bag shape. The rear end of the shaping plate is connected to the dialysis paper on one side of the bag opening, and the two sides of its front end gradually unfold and serve as forceps handles to open and rest against the edge.

[0005] Furthermore, a clamp handle hook is formed on one or both sides of the front end of the shaping plate.

[0006] Furthermore, a crease is provided between the pliers handle hook and the shaping plate.

[0007] Furthermore, the shaping board is a rigid cardboard with a waterproof coating on its surface.

[0008] Furthermore, the shaping plate is a medical-grade polypropylene plate or a medical-grade polyethylene plate.

[0009] Furthermore, the shaping plate has an upper crease or through groove on the side near the shielding bag along the opening direction of the shielding bag.

[0010] Furthermore, a horizontal crease is provided between the clamp handles on both sides of the front end of the shaping plate and the edge.

[0011] Furthermore, the sealing width B on both sides of the shielding bag is greater than or equal to 6mm.

[0012] Furthermore, the sealing width C at the bottom of the shielding bag is greater than or equal to 8 mm.

[0013] Compared with existing technologies, this utility model is applicable to the sterilization packaging structure of joint-type surgical instruments. The joint-type surgical instrument is in an open state, with the jaws extending into a shielding bag. The front end of the shaping plate is positioned between the jaw handles on both sides of the joint-type surgical instrument, and the jaw handles on both sides rest against the open edge of the jaw handles for support. Thus, the shaping plate keeps the jaw handles open, ensuring sterilization effectiveness. The dialysis paper and transparent plastic sealing film are heat-sealed on three sides to form a bag shape, which serves as a protective tip for the joint-type surgical instrument while maintaining the joint's position. The head model of the segmented surgical instruments is visible; the cost is low and meets the requirements of medical device packaging specifications; the sterilization effect is ensured by standardized opening angles; the design of hooks, creases, upper creases or through-hole grooves and horizontal creases on the forceps handles aims to make the shaping plate present a standardized application, making it convenient and quick to operate in practice; the transparent plastic sealing film resolves the contradiction between protection and visibility; the shaping plate adopts waterproof coated cardboard, medical-grade polypropylene board or medical-grade polyethylene board, which is easy to manufacture, and the cost of using waterproof coated cardboard is only 1 / 3 of that of medical plastic board.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Example 1: Please refer to Figure 1-6 As shown, a preferred embodiment of the sterilization packaging structure of this utility model for axial surgical instruments includes:

[0022] Shielding bag 1: It is formed by heat-sealing three sides of dialysis paper 11 and transparent plastic sealing film 12. The air permeability of the dialysis paper side 11 meets the sterilization requirements, while the transparent plastic sealing film 12 provides a visualization window.

[0023] Shape plate 2: The rear end is fixed to the dialysis paper side of the bag opening, and the two sides of its front end gradually extend to form a clamp handle 20, which is opened by a preset angle to ensure the instrument is in the open state.

[0024] The shaping board is a rigid cardboard with a waterproof coating on its surface; the shaping board 2 is a medical-grade polypropylene board or a medical-grade polyethylene board.

[0025] The sealing edge width on both sides of the shielding bag 1 is greater than or equal to 6mm, and the sealing edge width at the bottom of the shielding bag 1 is greater than or equal to 8mm, thereby enhancing the sealing reliability.

[0026] The shaping plate 2 has a clamp handle hook 21 formed on one or both sides of its front end. The purpose of the clamp handle hook 21 is to hang the shaping plate 2 on the clamp handle 30 on one or both sides of the joint-type surgical instrument 3, thereby maintaining the position of the shaping plate 2 and preventing the shaping plate 2 from falling off between the clamp handles 30 on both sides, thus preventing the support from failing.

[0027] When the extension distance of the forceps handle hook 21 is relatively long, a crease 22 is provided between it and the shaping plate 2. The purpose of the crease 22 is that when the shaping plate 2 passes between the forceps handles 30 on both sides of the joint-type surgical instrument 3, the forceps handle hook 21 can be folded along the crease 22, so that the shaping plate 2 can pass smoothly between the forceps handles 30 on both sides, and then the forceps handle hook 21 can be unfolded and hung on the forceps handle 30.

[0028] The shaping plate 2 has an upper fold 23 or a through groove 24 on the side near the shielding bag 1 along the opening direction of the shielding bag 1. The purpose of the upper fold 23 or through groove 24 is that, since the shaping plate 2 is attached to the dialysis paper 11 of the shielding bag 1, after being folded along the upper fold 23 or through groove 24 on the shaping plate 2, the shielding bag 1 is in an open state, so as to facilitate the insertion of the head 31 of the joint surgical instrument 3 into the cavity 10 of the shielding bag;

[0029] A horizontal crease 25 is provided between the front ends of the shaping plate 2 and the clamp handles 30. Protective wings may also be provided on both sides of the shaping plate 2. The purpose of the horizontal crease 25 is to allow the front end of the shaping plate 2 to be bent along the crease 25 and placed between the clamp handles 30 on both sides; the purpose of the protective wings is that when the front end of the shaping plate 2 is placed between the clamp handles 30 on both sides, the protective wings on both sides serve as bottom positioning supports for the clamp handles 30, that is, as bottom protective plates for the clamp handles 30.

[0030] Example 2: Figure 1-6 As shown, based on Example 1, the shaping plate 2 is made of 0.8mm thick medical polypropylene plate, and the shielding bag 1 is made of Tyvek® dialysis paper and PET transparent film heat-sealed together, with a sealing edge width of 8mm. In use, the surgical forceps handle 30 is inserted into the forceps handle hook 21, and the working end is naturally placed in the visible area of ​​the transparent film.

[0031] This structure has passed the YY / T 0698-2017 standard test for terminally sterilized medical device packaging materials, achieving zero breakage rate in dental extraction forceps packaging and 100% accuracy in device model identification.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
