Description

Technical Field

[0001] This utility model relates to a cleaning, disinfection, and placement structure for the threaded cap of a laparoscopic suction device. Background Technology

[0002] Laparoscopic aspirators play a crucial role in laparoscopic surgery, primarily used to aspirate fluid and blood from the surgical field, maintain a clear surgical view, and also to irrigate the surgical field, cool it, and prevent heat from spreading to surrounding tissues. Due to their specific function, a laparoscopic aspirator is included in every pack of laparoscopic instruments.

[0003] The Central Sterile Supply Department (CSSD) places postoperative laparoscopic instruments in a negative pressure washer for cleaning. This washer utilizes the property of water—lower pressure and lower boiling point—to create negative pressure by drawing air from the cleaning chamber. Combined with gas and liquid phase pulsation, this cleans the internal and external surfaces of instruments and items. The water in the cleaning chamber is heated for moist heat sterilization of the cleaned instruments and items. Finally, depressurization and heating are used to dry the instruments. To ensure that the laparoscopic aspirator is thoroughly cleaned of dirt and microorganisms after use, improving cleaning effectiveness and sterilization success rate, cleaning personnel disassemble it to its minimum size during the cleaning process. This involves breaking it down into its smallest unit. The disassembled aspirator components are placed in a parts loading basket, which is then placed in the cleaning and sterilization basket along with the laparoscopic instruments into the negative pressure washer. This ensures that every part is thoroughly cleaned, avoiding blind spots and residue.

[0004] One of the components after disassembly of the endoscopic suction device is the threaded cap, which is characterized by a heavier bottom and a lighter opening. During the cleaning process in the negative pressure cleaning machine, due to the decrease in pressure and pulsation inside the chamber, the water inside the chamber continuously boils and churns, and the instruments continuously vibrate. This causes the heavier bottom end of the threaded cap to face downwards, while the lighter opening end faces upwards, forming a "water-filled cap." Because the entire threaded cap is filled with water, the water cannot be completely dried during the subsequent vacuuming and heating drying stages. Often, after unloading the instruments, the entire threaded cap is filled with water. In fact, during the unloading process, the water in the threaded cap is easily poured into other instruments in the basket, requiring further drying by the packing personnel and affecting the instrument processing progress. At the same time, the water accumulation in the threaded cap poses a risk of substandard cleaning quality and inadequate cleaning effect. If instruments that are not properly dried are packed and sterilized, it is easy to create a wet package of instruments inside the bag, which also poses infection control problems such as substandard sterilization quality and inadequate sterilization effectiveness.

[0005] Therefore, how to avoid water accumulation in threaded caps after cleaning and disinfection, and how to prevent infection caused by inadequate disinfection, has become an urgent problem to be solved. Utility Model Content

[0006] This utility model addresses the problems existing in the prior art by providing a cleaning and disinfection placement structure for the threaded cap of a laparoscopic suction device. The structure is reasonably designed and effectively avoids water accumulation in the threaded cap after cleaning and disinfection.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a cleaning, disinfection, and placement structure for the threaded cap of a laparoscopic suction device, including an accessory loading basket, wherein a vertically arranged U-shaped fixing bracket is fixed to the inner bottom surface of the accessory loading basket, and the two vertical sections of the U-shaped fixing bracket are used to extend into the openings of the two threaded caps respectively.

[0008] Furthermore, the U-shaped fixing bracket includes a horizontal section and a vertical section that extends vertically after being folded at both ends of the horizontal section, and the horizontal section is fixedly connected to the bottom of the accessory loading basket.

[0009] Furthermore, each vertical segment is covered with an adhesive layer on its outer side.

[0010] Furthermore, the overlay layer is made of rubber.

[0011] Furthermore, the two threaded caps on the vertical sections at both ends of the U-shaped fixing bracket abut against each other.

[0012] Furthermore, the width of the vertical section is adapted to the inner diameter of the threaded cap, so that the vertical section of the U-shaped fixing bracket abuts against the inner wall of the threaded cap.

[0013] Furthermore, the horizontal section is connected and fixed to the bottom of the accessory loading basket via a connector.

[0014] Furthermore, a vertically penetrating mounting hole is provided in the middle of the horizontal section; the connector includes a shim nut, a connecting support pad, a connecting sleeve, and a connecting bolt. The connecting support pad is positioned below the accessory loading basket and its top surface contacts the outer bottom surface of the accessory loading basket. A connecting sleeve with a mesh hole penetrating the bottom of the accessory loading basket and extending into the mounting hole is fixed in the middle of the connecting support pad; the shim nut is positioned above the middle of the horizontal section; the connecting bolt is threaded through the shim nut and screwed into the connecting sleeve from the upper end to lock the U-shaped fixing bracket, the bottom of the accessory loading basket, and the connecting support pad together.

[0015] Furthermore, the connecting bolts are hexagon socket head cap screws.

[0016] Furthermore, the length of the horizontal section is greater than the mesh size at the bottom of the accessory loading basket; the connecting support pad is circular in shape, and the diameter of the connecting support pad is greater than the mesh size at the bottom of the accessory loading basket.

[0017] Compared with the prior art, the present invention has the following advantages: The present invention has a simple and reasonable structural design. By fixing a U-shaped fixing bracket at the bottom of the cleaning and disinfection basket, the two threaded caps of the endoscopic suction device are vertically inserted into the vertical sections at both ends of the U-shaped fixing bracket, which effectively avoids water accumulation in the threaded caps after cleaning and disinfection, and eliminates the infection caused by inadequate disinfection.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-7 As shown, this utility model discloses a cleaning and disinfection placement structure for the threaded caps of a laparoscopic aspirator. It includes a rectangular accessory loading basket 1, with each surface being mesh-like. A vertically mounted U-shaped fixing bracket 2 is fixed to the inner bottom surface of the accessory loading basket 1. The vertical sections at both ends of the U-shaped fixing bracket 2 are used to insert into the openings of two threaded caps 3, with the lighter end of the threaded cap 3 facing downwards and the heavier end facing upwards. During operation, the disassembled components of the laparoscopic aspirator are placed into the accessory loading basket 1. The two threaded caps 3 are inserted from top to bottom into the vertical sections at both ends of the U-shaped fixing bracket 2. The entire cleaning and disinfection basket is then sent into a negative pressure cleaning machine for cleaning. Because the threaded caps are stably supported by the vertical sections of the U-shaped fixing bracket, keeping the openings facing downwards, water will not accumulate at the lighter end during the negative pressure cleaning process, effectively preventing water accumulation after cleaning and disinfection and eliminating infection caused by inadequate disinfection.

[0030] In this embodiment, as Figure 3 As shown, the U-shaped fixed bracket 2 includes a horizontal section 21 and a vertical section 22 that extends vertically after being folded at both ends of the horizontal section 21. The horizontal section 21 is fixedly connected to the bottom of the accessory loading basket 1.

[0031] In this embodiment, each vertical segment 22 is covered with an adhesive layer 4 on its outer side. Preferably, the adhesive layer can be made of rubber. By providing an adhesive layer on the outer side of the vertical segment, damage to the inner wall of the threaded cap can be avoided.

[0032] In this embodiment, the U-shaped fixing bracket 2 is made of stainless steel, which can withstand high temperature cleaning and is not easy to rust after use.

[0033] In this embodiment, the two threaded caps 3 are inserted vertically into the outer peripheral surfaces of the vertical sections 22 at both ends of the U-shaped fixing bracket 2. In the U-shaped fixing bracket, the vertical section forms a cantilever structure. The vertical sections at both ends of the horizontal section can be appropriately bent, so that the entire U-shaped fixing bracket has appropriate elasticity. In use, the vertical section is first slightly bent outward, and then one threaded sleeve is inserted. The other threaded sleeve is inserted in the same way. After both threaded sleeves are inserted, the elasticity of the vertical section can appropriately act on the threaded caps, so that the two threaded caps are tightly abutted together and are not easy to slip off.

[0034] In this embodiment, the width of the vertical section 22 is adapted to the inner diameter of the threaded cap 3. When the threaded cap is inserted into the vertical section, the vertical section 22 of the U-shaped fixing bracket 2 can abut against the inner wall of the threaded cap 3, making it difficult for the threaded sleeve to easily slip off the vertical section.

[0035] In this embodiment, the horizontal section 21 is connected and fixed to the bottom of the accessory loading basket 1 via a connector. Specifically: a vertically penetrating mounting hole 23 is provided in the middle of the horizontal section 21; the connector includes a shim nut 8, a connecting support pad 5, a connecting sleeve 6, and a connecting bolt 7. The connecting support pad 6 is located below the accessory loading basket 1, and the top surface of the connecting support pad 5 contacts the outer bottom surface of the accessory loading basket 1. The connecting sleeve 6 is fixed in the middle of the connecting support pad 5. The connecting sleeve 6 penetrates vertically through the mesh 10 at the bottom of the accessory loading basket 1 and extends into the mounting hole 23. The inner wall of the connecting sleeve 6 is provided with connecting threads; the shim nut 8 is located above the middle of the horizontal section 21; the connecting bolt 7 is threaded through the shim nut 8 and screwed into the connecting sleeve 6 from the top end. The bottom of the bolt head of the connecting bolt abuts against the top surface of the shim nut to lock the U-shaped fixing bracket 2, the bottom of the accessory loading basket 1, and the connecting support pad 5 together. Preferably, the shim nuts, connecting support pads, connecting sleeves, and connecting bolts are all made of stainless steel, which is resistant to high temperature cleaning and is not easy to rust.

[0036] In this embodiment, the connecting bolt 7 is an internal hex bolt.

[0037] In this embodiment, the mesh at the bottom of the accessory loading basket 1 is rectangular, and the length of the horizontal section 21 is greater than the mesh size (length and width) at the bottom of the accessory loading basket 1, so as to stably support the horizontal section; the connecting support pad 5 is circular, and the diameter of the connecting support pad 5 is greater than the mesh size (length and width) at the bottom of the accessory loading basket 1.

[0038] It should be noted that, in actual production and processing, the size of the U-shaped fixation bracket can be determined according to the size of the threaded cap of the endoscopic suction device. The spacing between the vertical sections at both ends of the U-shaped fixation bracket can be set as needed, and it can also be used for fixing, cleaning, and disinfecting other instruments or accessories.

[0039] This invention is mainly used in disinfection supply centers to fix the threaded cap of the endoscope suction device when disassembling and cleaning it, so as to avoid residual cleaning solution after cleaning and disinfection.

[0040] In this embodiment, the accessory loading basket is a commonly used accessory in the disinfection supply center. This utility model simply involves fixing a U-shaped fixing bracket inside the accessory loading basket. The modification is simple, and the U-shaped fixing bracket has a simple structure and low cost. It has the advantages of low cost, good results, and convenient installation, and is well worth promoting and using.

[0041] With the continuous development of medical technology, laparoscopic surgery is becoming increasingly accepted by patients. The central sterile supply department is receiving more and more different types of laparoscopic instruments, and the number of laparoscopic suction devices included with each instrument is also increasing. Therefore, the quality of their cleaning and sterilization must be given high priority. Laparoscopic instruments need to be cleaned and sterilized in specific negative pressure cleaning equipment. Given their unique working principle, preventing water accumulation after disassembly is crucial. It is essential to add a U-shaped fixing bracket to the accessory loading basket to ensure the quality of cleaning, sterilization, and even sterilization, thus ensuring effective infection control from the very beginning.

[0042] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0043] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0044] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
