Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically relating to a biological valve cleaning device. Background Technology

[0002] An artificial heart valve (or heart valve prothesis) is an implantable organ that replaces the natural heart valves (aortic, tricuspid, or mitral valves), allowing blood to flow in one direction. It functions like a natural heart valve. When heart valve disease is severe and valve function cannot be restored or improved through valve separation or repair surgery, artificial heart valve replacement surgery is necessary. Artificial valves are classified into two main categories based on the materials used: mechanical valves are made entirely of artificial materials, while bioprosthetic valves are made wholly or partially of biological tissue.

[0003] Bioprosthetic valves are preserved by directly immersing them in a preservative solution containing a bactericide in a sealed container. If the preservative solution is not thoroughly cleaned, the patient may experience fever after surgery or it may affect valve function, such as causing valve calcification. Therefore, the preservative solution must be completely removed before use. The traditional cleaning method involves manually connecting the valve holder to the bioprosthetic valve, then completely immersing the bioprosthetic valve in 500 ml of 9% sodium chloride injection solution, and manually moving it back and forth for two minutes, repeating this three times.

[0004] However, manual flushing is susceptible to human error, leading to uneven flushing and potentially leaving residual preservation fluid on the bioprosthetic valve surface. This can not only trigger postoperative fever but also shorten the valve's lifespan, making it prone to dysfunction and even calcification. In such cases, valve replacement is necessary, impacting the patient's health and increasing their financial burden. Furthermore, assigning a dedicated person to clean the bioprosthetic valve during surgery wastes human resources and increases the cost of consumables (the cost of cleaning and sterilizing disinfectant, sterile surgical gowns, masks, caps, gloves, and slippers for a dedicated person on the operating table is substantial).

Detailed Implementation

[0021] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] This embodiment provides a biological valve cleaning device, including a placement net 1, an antibacterial cover 2, a robotic arm 3, and a cleaning tank 4.

[0023] The antibacterial cover 2 is detachably mounted on the moving end of the robotic arm 3; The placement net 1 has an opening at one end, and the open end of the placement net 1 is detachably connected to the antibacterial cover 2. The placement net 1 is used to accommodate the valve. For example, see Figure 1-2The placement net 1 is a cylindrical mesh structure with an open top, used to hold the valves to be cleaned. The top of the placement net 1 is fixed to the bottom of the antibacterial cover 2 by screwing or snapping, so that the antibacterial cover 2 and the placement net 1 are assembled as a whole, and the antibacterial cover 2 and the placement net 1 are coaxial. The antibacterial cover 2 can close the top opening of the placement net 1 to prevent the valves from detaching from the placement net 1. The top of the antibacterial cover 2 is fixed to the moving end of the robotic arm 3 by screwing or snapping, so that the robotic arm 3 can drive the antibacterial cover 2 and the placement net 1 to move synchronously.

[0024] Cleaning tank 4 is used to hold cleaning solution; For example, see Figure 1-2 The cleaning tank 4 is a cylindrical structure with an open top, and the net 1 can be completely inserted into the cleaning tank 4. The cleaning tank 4 contains cleaning fluid for cleaning the valves.

[0025] Based on the above structure, the biological valve cleaning device provided in this embodiment loads the valve to be cleaned into the placement net 1, then connects the placement net 1 to the antibacterial cover 2, connects the antibacterial cover 2 to the moving end of the robotic arm 3, and then drives the placement net 1 into the cleaning tank 4 through the robotic arm 3, so that the valve in the placement net 1 is immersed in the cleaning solution of the cleaning tank 4. Finally, the placement net 1 is rotated by the robotic arm 3 to achieve the cleaning of the valve.

[0026] The placement net 1 can accommodate valves of different sizes, eliminating the need for equipment adjustments when cleaning valves of varying sizes, thus effectively improving the equipment's adaptability and cleaning efficiency. Furthermore, assembling the placement net 1 and the antibacterial cover 2 as a single unit prevents accidental drops during transport, which could lead to valve contamination.

[0027] Based on the above technical solution, the biological valve cleaning device provided in this embodiment also includes a cleaning platform 5, on which a placement groove 6 adapted to the cleaning tank 4 is provided, and the cleaning tank 4 is embedded in the placement groove 6. For example, see Figure 1-2 The cleaning platform 5 has three placement slots 6, corresponding to three cleaning slots 4. The bottom ends of the three cleaning slots 4 are embedded in the three placement slots 6 to form a stable structure. A robotic arm 3 is mounted on the cleaning platform 5, which also has a control panel 8. The control panel 8 integrates a controller, which is electrically connected to the robotic arm 3. The control panel 8 allows setting the movement mode of the robotic arm 3, the cleaning time, and the cleaning action (rotation mode of the placement net 1, circumferential rotation or reciprocating alternating rotation). It can also stop the cleaning action after the set cleaning time is reached and issue a prompt (early sound or indicator light, etc.). Built-in parameters for different types of valves can be switched in real time via the control panel 8 to ensure consistent cleaning results and avoid human interference. The built-in parameters can also be adjusted individually by comparing cleaning results.

[0028] Among them, the inner diameter of the cleaning tank 4 gradually decreases from top to bottom; the diameter of the antibacterial cover 2 is larger than the inner diameter of the top opening of the cleaning tank 4; For example, see Figure 1-2 The inner diameter of the cleaning tank 4 is largest at the top and gradually decreases from top to bottom, which facilitates the placement of the net 1 into the cleaning tank 4 through the top opening. The diameter of the antibacterial cover 2 is larger than that of the cleaning tank 4. When the net 1 is placed into the cleaning tank 4, the antibacterial cover 2 can completely cover the top opening of the cleaning tank 4, which can prevent foreign objects from falling into the cleaning tank.

[0029] The biological valve cleaning device provided in this embodiment also includes a cleaning component 7, which is fixedly connected to three cleaning tanks 4. For example, see Figure 1-2 The cleaning component 7 is horizontally positioned and has three connecting holes. Three cleaning tanks 4 are located within these holes, allowing the cleaning component 7 to connect the three tanks 4 into a single unit. The three tanks 4 can be used for three cleaning cycles and can be replaced after each use, making them easier to handle. Furthermore, the cleaning component 7 serves to collect water, preventing the cleaning solution from splashing out of the tanks 4 and affecting the environment.

[0030] Among them, the cleaning component 7, the cleaning tank 4, the antibacterial cover 2, and the placement net 1 are all disposable sterile consumables, which are very convenient to use and replace.

[0031] In the technical solution provided in this embodiment, the robotic arm 3 is existing technology. For example, the robotic arm 3 may include a first rotating mechanism, a lifting mechanism, and a second rotating mechanism. The moving end of the robotic arm 3 is mounted on the rotating end of the first rotating mechanism, the first rotating mechanism is mounted on the lifting end of the lifting mechanism, and the lifting mechanism is mounted on the rotating end of the second rotating mechanism. Thus, the second rotating mechanism allows the lifting mechanism to rotate around the axis of the first rotating mechanism, and the lifting mechanism allows the first rotating mechanism to be raised or lowered, thereby adjusting the positions of the placement net 1 and the antibacterial cover 2. Finally, the first rotating mechanism allows the moving end of the robotic arm 3 to rotate, thereby rotating the placement net 1 and the antibacterial cover 2.

[0032] In the technical solution provided in this embodiment, the antibacterial cover 2 is provided with a connecting cylinder 9 with internal threads, the opening end of the placement net 1 is provided with external threads, and the opening end of the placement net 1 is screwed to the connecting cylinder 9. For example, see Figure 3The bottom end of the antibacterial cover 2 is coaxially fixed with a connecting cylinder 9 with internal threads. The connecting cylinder 9 and the antibacterial cover 2 are an integral structure, with the opening of the connecting cylinder 9 facing downwards. The top end of the placement net 1 has external threads, and the top end of the placement net 1 is screwed to the connecting cylinder 9 for easy assembly and disassembly. A limiting ring is fixedly sleeved on the outer side of the placement net 1, located below the external threads. When the limiting ring abuts against the bottom end of the connecting cylinder 9, the rotation of the placement net 1 stops. This prevents the placement net 1 from rotating too much or too little, which could lead to inconsistent height positioning.

[0033] In the technical solution provided in this embodiment, the antibacterial cover 2 is provided with a card plate 10, the side wall of the card plate 10 has a protrusion, the moving end of the robotic arm 3 is provided with a connector 11, the connector 11 is provided with an insertion hole 12 adapted to the card plate 10, the inner side wall of the insertion hole 12 is provided with a sliding groove 13, the sliding groove 13 is provided with a sliding member 14 and an elastic member 15, the sliding member 14 slides with the sliding groove 13, the sliding member 14 is provided with a groove adapted to the protrusion, and the two ends of the elastic member 15 are respectively connected to the sliding member 14 and the inner wall of the sliding groove 13.

[0034] For example, see Figure 3 A mounting plate 10 is fixedly installed at the center of the top of the antibacterial cover 2. The mounting plate 10 has protrusions on both the left and right side walls. A connector 11 is fixedly installed at the moving end of the robotic arm 3. The bottom end of the connector 11 has an insertion hole 12. The inner side walls of the insertion hole 12 have sliding grooves 13. Sliding elements 14 and elastic elements 15 are provided in both sliding grooves 13. The elastic element 15 is a spring. The right end of the left sliding element 14 has a groove, and the left end of the right sliding element 14 has a groove.

[0035] During assembly, the card holder 10 is inserted into the insertion hole 12. The protrusions on both sides of the card holder 10 can squeeze the sliding member 14, causing the sliding member 14 to slide into the slide groove 13. The elastic member 15 is compressed until the protrusion of the card holder 10 enters the groove of the sliding member 14. The sliding member 14 moves out of the slide groove 13, and the groove fits with the protrusion. At this time, the sliding member 14 can limit the card holder 10, thereby realizing the carding and fixing of the antibacterial cover 2 and the moving end of the robotic arm 3.
