Description

Technical Field

[0001] This utility model relates to the field of medical device cleaning equipment technology, specifically to a support and fixation device for cleaning the core of endoscopic instruments. Background Technology

[0002] Laparoscopic surgical instruments have a sophisticated structure, with their cores typically containing complex lumens and joints. During cleaning and disinfection, if the instrument core is in a closed or semi-closed state, the lumens and joints cannot be fully rinsed by the cleaning solution, leaving behind contaminants and posing a potential source of hospital-acquired infections.

[0003] Currently, the cleaning of laparoscopic instrument cores mostly relies on manual opening and placement in a cleaning basket. This method has significant drawbacks: firstly, the degree of opening is inconsistent and cannot guarantee that all lumens and joints can be fully exposed, easily resulting in cleaning blind spots; secondly, randomly placed instruments may obstruct the flow of cleaning fluid, affecting the cleaning effect, and scattered instruments are also inconvenient to retrieve after cleaning.

[0004] Therefore, there is an urgent need for a device for opening and fixing laparoscopic instrument cores to solve the aforementioned cleaning problem. Utility Model Content

[0005] This invention provides a device for opening and fixing endoscopic instrument cores to address the aforementioned problems in the prior art. It can effectively solve the problems of non-standard instrument core opening, insecure fixation, and poor cleaning effect in the prior art, and is also easier to place and remove in the cleaning equipment.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for opening and fixing a cleaning endoscope instrument core, characterized in that it includes a base and at least one opening and fixing unit disposed on the base; the opening and fixing unit includes: an opening member for opening the head of the instrument core, the opening member being fixed at one end near the base and near the outer edge of the base; The fastener is used to fix the handle of the instrument core. The fastener is fixed at the other end near the base and near the outer edge of the base. The fastener is provided with a fixing groove for securing the handle of the instrument core. The space between the expanding member and the fixing member is for placing the instrument core body.

[0007] Furthermore, the base is provided with a plurality of the aforementioned spreading and fixing units, which are arranged in a ring array around the center line of the base.

[0008] Furthermore, the opening members of the multiple opening and fixing units are connected end to end to form a ring-shaped structure.

[0009] Furthermore, a first clearance groove is provided on the outer edge of the base end corresponding to the support member.

[0010] Furthermore, the fixing member is a pad structure, preferably a disc-shaped pad made of rubber, with multiple fixing slots opened along its outer edge in the circumferential direction.

[0011] Furthermore, the pad and the base are detachable.

[0012] Furthermore, the pad is movably embedded in the end of the base, and the end of the base has a receiving groove for placing the pad, and an anti-detachment block is provided at the opening of the receiving groove to prevent the pad from falling out of the receiving groove.

[0013] Furthermore, a second clearance groove is provided on the outer edge of the base end corresponding to the fixing slot, so that the instrument core handle can be placed in the fixing slot through the second clearance groove.

[0014] Furthermore, the fixing slot faces the outside of the base.

[0015] Furthermore, the core of the base is provided with through holes penetrating both ends of the base.

[0016] The beneficial effects of this utility model are: 1. This utility model uses a support and fixing unit composed of a support member and a fixing member located near the outer edges of both ends of the base. The space between the support member and the fixing member is for placing the instrument core body. By supporting the head of the instrument core at one end and reliably fixing the handle of the instrument core at the other end, the middle section of the instrument core and the joint part are completely suspended and exposed, which effectively avoids the generation of cleaning dead corners and ensures that the cleaning fluid can fully rinse the instrument from all angles, significantly improving the cleaning quality and reliability.

[0017] 2. This utility model further improves upon the previous invention by setting multiple supporting and fixing units arranged in a circular array around the center line of the base, so that multiple fixed instrument cores are arranged in an orderly circular array, resulting in a compact structure and high space utilization. This layout not only facilitates operators to quickly pick up and put down instruments at the same workstation, greatly improving operational efficiency, but also ensures that the instruments are neatly arranged in the cleaning basket, avoiding tangling and obstruction, and facilitating centralized retrieval and management after cleaning.

[0018] 3. The present invention further provides that the multiple opening and fixing units are connected end to end to form a ring structure, and cooperate with the first clearance groove provided on the outer edge of the base end, providing sufficient operating space for the opening operation of the instrument core head, and facilitating the placement and positioning of the instrument.

[0019] 4. This utility model further designs the fixing component and the base as a separable structure, which can replace the fixing component with a fixing slot of different specifications when needed, so as to be suitable for fixing instrument cores of different sizes (such as the outer diameter of the instrument core handle), thus making it more versatile.

[0021] To make the objectives, technical solutions, and advantages 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 for explaining the present utility model and are not intended to limit the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0023] like Figure 1 As shown, the device for opening and fixing the cleaning endoscope instrument core in this embodiment includes a base 1 that is roughly dumbbell-shaped (wide at both ends and narrow in the middle). The core of the base 1 is provided with a through hole 6 that runs through the upper and lower ends of the base 1 to facilitate the flow of the cleaning medium. This not only enhances the rinsing effect on the instrument itself, but also improves the fluid dynamic environment inside the entire cleaning device, further ensuring the thoroughness of cleaning and disinfection.

[0024] On the base 1, ten expansion and fixing units 2 are arranged in a circular array around its center line. Each expansion and fixing unit 2 includes an expansion member 3 and a fixing member 4. The expansion member 3 and the fixing member 4 are connected without any obstruction, serving as a space for placing the instrument core body. The expansion member 3 is used to expand the head of the instrument core. The expansion member 3 is fixed near one end of the base 1 and near the outer edge of the base 1. A first clearance groove 7 is machined on the outer edge of the end of the base 1 corresponding to each expansion member 3. This design provides the necessary operating space for the insertion and expansion of the instrument core head. The fixing member 4 is used to fix the handle of the instrument core. Specifically, it is a disc-shaped rubber pad. Its elastic properties effectively clamp the handle to prevent loosening and avoid surface damage to the precision instrument that may be caused by hard contact. Located near the other end of the base 1 and near the outer edge of the base 1, the outer edge of the fixing member 4 is provided with ten fixing slots 5 for securing the instrument core handle along its circumference. The fixing slots 5 are specifically facing the outer side of the base 1 so that the instrument core can be inserted into the fixing slots 5 through the outer side of the base 1. The outer edge of the end of the base 1 is provided with a second clearance groove 8 corresponding to each fixing slot 5, so as to provide the necessary operating space for the instrument core handle to be placed and secured in the fixing slot 5, so that the instrument handle can be easily inserted into the fixing slot laterally, simplifying the clamping steps.

[0025] The usage process of this embodiment is as follows: The operator holds the endoscope instrument core and first places its head 9 (usually the end with a joint or complex structure) on the spreader 3. The spreader 3 is used to spread the head open, ensuring that the lumen and joint parts of the instrument core 3 are fully exposed to ensure cleaning effect. Then, the handle 10 of the instrument core is inserted into the corresponding fixing slot 5 of the fixing member 4 through the second clearance groove 8 on the outside of the base 1. Figure 4 and Figure 5 As shown. Because the fixing component 4 is made of elastic rubber, the fixing groove 5 can produce slight deformation, thereby flexibly and firmly holding the instrument handle. Combined with the limiting of the head by the expansion component 3, this prevents the instrument from shaking or falling off during the cleaning process and avoids hard scratches. Repeating this operation, the remaining nine expansion and fixing units 2 can be fixed with the instrument cores. All instrument cores 3 are fixed in a ring array, suspended in the air, with a neat and orderly structure. Finally, the entire device is placed in the basket of the automated cleaning equipment through its base 1. The cleaning fluid or steam can flow fully through the through hole 6 in the center of the base 1 and the gaps between the instruments, achieving a thorough cleaning of the instrument cores from all directions.

[0026] In a preferred embodiment of this utility model, see Figure 1As shown, the ten supporting members 21 are connected end to end to form an integrated ring structure around the center line of the base 1, which is convenient for assembly and processing, and can be fixedly integrated on the base 1. Together with the first relief groove 7, it can play a supporting role while ensuring the flow of cleaning fluid.

[0027] In a preferred embodiment of this utility model, see Figure 2 and Figure 3 As shown, the fixing component 2, i.e., the rubber pad, and the base 1 are detachable, allowing for replacement of the fixing component. This enables the selection of a pad structure with a suitable fixing slot 5 to be connected to the base 1 when cleaning instrument cores of different sizes. Furthermore, the pad is movably embedded in the end of the base 1, and the end of the base 1 has a receiving groove 11 adapted to the outer dimensions of the pad for placing the pad. An anti-detachment block 12 is provided at the opening of the receiving groove 11 to prevent the pad from detaching. This anti-detachment block 12 can be installed on the base 1 by screw fixing or snap-fit ​​connection, or... Figure 3 The anti-detachment block 12 and the base 1 are designed as an integral structure. This facilitates the replacement of the pad while ensuring the stability of the pad within the base, thereby guaranteeing the stability of the instrument core it fixes. The advantage of this embodiment is that when the fixing component 2 wears down due to long-term use or needs to be replaced with a pad of a different size to adapt to a new instrument, simply remove the anti-detachment block 2 to take the old fixing component 2 out of the receiving groove 2 for replacement. Maintenance is very convenient, reducing long-term operating costs.

[0028] In summary, this invention not only solves the core problems of non-standard instrument opening and insecure fixation, but also significantly improves the ease of operation, space utilization and maintenance through overall structural layout and detail optimization. It can also effectively promote the flow of cleaning media, thereby comprehensively optimizing the cleaning effect and work efficiency of endoscopic instrument cores.
