[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention involves inserting the used sampling knife into the processing tank through the inlet. The knife is protected and buffered by a protective plate and a buffer plate. After passing through these plates, the sampling knife slides from the buffer plate surface into the cleaning tank. A pump extracts cleaning water from the cleaning chamber and injects it into the cleaning tank through a cleaning pipe. The cleaning water is then sprayed out through a cleaning head to rinse the surface of the sampling knife. The rinsed wastewater leaks into the bottom of the cleaning tank through a leak hole and is guided by an inclined plate to flow into a collection tank through a drain pipe. This initial cleaning of the sampling knife prevents impurities and blood from remaining on its surface, which could affect subsequent steps. It also makes the retrieval of the sampling knife more convenient.

[0018] 2. In this invention, the first and second clamping components are moved by the second and third electric push rods, respectively, so that both the first and second clamping components are positioned above the cleaning tank. A sixth electric push rod moves the slider on the slide surface, changing its position. Then, a fourth electric push rod moves the mounting plate downwards, causing the mounting plate to bring the clamping components closer to the cleaned sampling knife. The clamping components of the first clamping component clamp the blade of the sampling knife, and the clamping components of the second clamping component clamp the handle of the sampling knife. During clamping, a fifth electric push rod pushes a push block, causing the push block to move the clamping plate on the connecting plate. The device rotates within the bottom rotating groove, causing the clamping plate and clamping blocks to move closer together, thereby clamping the knife handle or blade. After clamping, the first or second clamping assembly is moved by the second and third electric push rods, while the fourth electric push rod moves the entire sampling knife upwards. When the sampling knife is above the placement plate, the third electric push rod stops moving, while the second electric push rod continues to move, causing the blade of the sampling knife to move and thus separating the blade from the knife handle. At this point, the clamping components are released, allowing the disassembled sampling knife to fall onto the surface of the placement plate. Through automatic retrieval and disassembly, the risks associated with manual disassembly of the sampling knife are avoided.

[0019] 3. This invention uses a drive motor to rotate a placement plate, causing the blade handle and blade on the surface of the placement plate to fall onto the filter screen surface inside the disinfection chamber. A pump extracts disinfectant from the disinfection chamber and injects it into the chamber through a distribution pipe. Then, a first electric push rod lowers the filter screen until it is completely submerged in the disinfectant, disinfecting the blade and handle. After disinfection, the first electric push rod lifts the filter screen, removing it and the blade and handle from the disinfectant. A hot air fan is activated to dry the blade and handle on the filter screen surface. After drying, a first clamping component and a second clamping component clamp the blade and handle, respectively, and then reassemble them. The assembled blade and handle are placed on the first and second placement components, with a first squeezing clamp securing the handle and a second squeezing clamp securing the blade. The first and second squeezing clamps are secured to the handle and blade respectively by a first spring and a second spring, facilitating easy access without manual disassembly and significantly improving the safety of the sampling knife during assembly and disassembly.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] As attached Figure 1 To be continued Figure 12 As shown:

[0037] Example 1: This invention provides an integrated automatic device for cleaning, storing, and disassembling a pathological sampling scalpel, including a base pad 1. A mounting mechanism 2 is fixed to the top of the base pad 1. The mounting mechanism 2 includes a processing box 21. A dispensing port 23 is opened on one side of the processing box 21. A protective plate 22 is fixed to the inner wall of the dispensing port 23. A buffer plate 24 is fixed to the inner wall of the processing box 21 below the dispensing port 23. A cleaning mechanism 3 is provided at the bottom of the inner cavity of the processing box 21. A placement mechanism 4 and a disinfection mechanism 5 are provided in the middle of the inner cavity of the processing box 21. The disinfection mechanism 5 is connected to an external liquid supply assembly. A clamping mechanism 7 is provided at the top of the inner cavity of the processing box 21. The clamping mechanism 7 is used for... The system is designed to hold and disassemble pathological sampling knives. A door 6 is located on one side of the processing box 21. A storage mechanism 8 is located on the inner wall of the processing box 21, next to the door 6. The storage mechanism 8 is used to store disassembled or reassembled pathological sampling knives. A cleaning mechanism 3 is used to rinse the surface of the used pathological sampling knives. A disinfection mechanism 5 is used to disinfect the rinsed pathological sampling knives. The protective plate 22 has an arc-shaped structure, and a rubber buffer layer is fixed to the inner wall of the protective plate 22. The surface of the buffer plate 24 has anti-slip textures, and the angle between the buffer plate 24 and the inner wall of the processing box 21 is 30-45 degrees, used to guide the pathological sampling knives to slide smoothly into the cleaning mechanism 3.

[0038] The base pad 1 is made of high-density polyurethane or medical-grade rubber. This material not only has excellent anti-slip properties, preventing displacement of the device due to vibration during use, but also has a good cushioning effect, reducing the impact on the placement surface when the device is running. The processing box 21 is made of medical-grade 304 stainless steel. 304 stainless steel has excellent corrosion resistance and high temperature resistance, and its smooth surface is easy to clean, effectively preventing blood, tissue residue, and disinfectant corrosion, meeting the hygiene standards of the pathology department. The protective plate 22 has an arc-shaped structure. Its base is made of thin 304 stainless steel, and the buffer layer fixed to the inner wall is made of medical-grade silicone rubber. Silicone rubber is non-toxic, odorless, and has strong chemical stability, which can prevent contamination when in contact with the sampling knife, and can also absorb the impact force when the knife is dropped. The buffer plate 24 is also made of 304 stainless steel, and the surface is sandblasted to form a uniform anti-slip texture, which not only increases the friction when the knife slides down, but also facilitates subsequent cleaning.

[0039] During operation, the used pathological sampling scalpel is inserted into the device by the operator through the insertion port 23 on one side of the processing box 21. During insertion, the arc-shaped protective plate 22 first guides the scalpel to prevent it from directly impacting the side wall of the box. The silicone rubber buffer layer on its inner wall further weakens the kinetic energy of the falling scalpel and prevents the blade edge from being damaged by impact. Then the scalpel falls onto the buffer plate 24 below. The buffer plate 24 forms a 30-45 degree angle with the inner wall of the processing box 21. This angle is optimized to ensure that the scalpel slides smoothly under its own weight without causing the blade to bump or deviate due to excessive sliding speed. Finally, the scalpel falls precisely into the cleaning mechanism 3 located at the bottom of the inner cavity of the processing box 21, completing the initial insertion and guidance process.

[0040] In one embodiment of the present invention, the cleaning mechanism 3 includes a water storage tank 31 and a cleaning chamber 35. The top of the water storage tank 31 is provided with a water inlet 32. A cleaning pipe 33 is fixed on the inner wall of the water storage tank 31. A plurality of cleaning heads 34 are connected to the outer wall of the cleaning pipe 33. The cleaning chamber 35 is located at the bottom of the processing box 21. A leakage hole 36 is provided at the bottom of the cleaning chamber 35. An inclined plate 37 is fixed on the inner wall of the cleaning chamber 35 below the leakage hole 36. A drain pipe 38 is connected to the bottom of the inclined plate 37. The end of the drain pipe 38 away from the inclined plate 37 is connected to the sludge collection tank 39. A liquid pump for drawing cleaning water is provided on the water storage tank 31. The liquid pump is connected to the cleaning pipe 33. The cleaning heads 34 are located inside the cleaning chamber 35.

[0041] Both the water storage tank 31 and the cleaning chamber 35 are welded from 304 stainless steel. The water storage tank 31 is used to store cleaning water, and its inner wall is polished to reduce the adhesion of scale and impurities. The cleaning pipe 33 is made of PVC pipe, which is corrosion-resistant, lightweight, and has a smooth inner wall that does not easily breed bacteria. The multiple cleaning heads 34 connected to the outer wall of the cleaning pipe 33 are made of stainless steel, and the nozzles are precision machined to form a high-pressure fan-shaped water flow. The inclined plate 37 is made of 304 stainless steel plate, and the surface slope is controlled at 15-20 degrees to facilitate the rapid diversion of sewage. The sewage pipe 38 is made of acid and alkali resistant PVC pipe, which can withstand the corrosion of residual blood and tissue decomposition products in the sewage after cleaning. The sludge collection tank 39 is made of high-strength polyethylene, which is lightweight, impact-resistant, and easy to disassemble and clean. The liquid pump is a medical-grade micro centrifugal pump, and the pump body and the parts in contact with the liquid are made of stainless steel to ensure that the cleaning water is not contaminated.

[0042] During operation, before the cleaning process starts, clean water that meets the hygiene requirements of the pathology department is injected through the water inlet 32 ​​at the top of the water storage tank 31. Medical neutral cleaning agent can be added as needed. Then, the pump is powered on and runs to draw the cleaning water in the water storage tank 31 into the cleaning pipe 33. The cleaning pipe 33 is evenly arranged along the inner wall of the cleaning chamber 35, and multiple cleaning heads 34 on its outer wall spray high-pressure fan-shaped water jets at the same time. The water jets rinse the sampling knives that fall into the cleaning chamber 35 from different angles, which can fully cover the blade edge, the handle connection and other parts that are prone to residual tissue and blood, and thoroughly wash away the surface dirt. The wastewater generated by rinsing carries impurities and falls into the inclined plate 37 below through the leakage hole 36 at the bottom of the cleaning chamber 35. The slope of the inclined plate 37 makes the wastewater flow quickly to the bottom and is discharged into the collection tank 39 through the connected drain pipe 38, realizing the recycling of cleaning water (if a filter component is installed, water resources can be further saved) and centralized collection of wastewater.

[0043] In one embodiment of the present invention, the placement mechanism 4 includes a side plate 41 fixed to the inner wall of the processing box 21. Two side plates 41 are provided, and a vertical plate 43 is fixedly connected between the two side plates 41. The bottom of the vertical plate 43 is fixedly connected to the bottom of the processing box 21. A side block 44 is provided at the bottom of the side plate 41. A placement plate 45 is rotatably connected between the side blocks 44. A rotating shaft is provided on both sides of the placement plate 45. The rotating shaft on one side of the placement plate 45 is rotatably connected to the side block 44. The rotating shaft on the other side of the placement plate 45 passes through the side block 44 and extends to the outside of the processing box 21. A drive motor 42 is provided at one end of the rotating shaft located outside the processing box 21. The output shaft of the drive motor 42 is fixedly connected to the rotating shaft. The placement plate 45 is used to receive the pathological sampling knife delivered from the cleaning mechanism 3.

[0044] The side plate 41, vertical plate 43, side block 44, and placement plate 45 are all made of 304 stainless steel. The side plate 41 and vertical plate 43 are welded to the inner wall of the processing box 21 to form a stable support structure. The bottom of the vertical plate 43 is welded to the bottom of the processing box 21 to further improve the overall rigidity. The rotating shafts on both sides of the placement plate 45 are made of No. 45 steel and the surface is nitrided with a nitriding layer thickness of 0.1-0.2mm, which can significantly improve the wear resistance and fatigue resistance of the rotating shaft. The drive motor 42 is a stepper motor with an IP65 protection rating. The stepper motor can achieve precise angle control. The IP65 protection rating can effectively isolate moisture and water mist inside the processing box 21 to prevent damage to the internal components of the motor from moisture. The motor housing is made of aluminum alloy, which is lightweight and has good heat dissipation performance.

[0045] After cleaning, the clamping mechanism 7 transfers the cleaned cutting tools to the placement plate 45 of the placement mechanism 4. When the tools need to be transported to the disinfection mechanism 5, the drive motor 42 is powered on and started. Its output shaft drives the rotating shaft on one side of the placement plate 45 to rotate. The rotating shaft is connected to the side block 44 through a bearing to ensure smooth rotation. The placement plate 45 rotates synchronously with the rotating shaft. The rotation angle is set to 45-60 degrees according to the position of the disinfection chamber 54. At this time, the cutting tools on the surface of the placement plate 45 slide smoothly down the surface of the placement plate 45 onto the filter screen 55 of the disinfection mechanism 5 under the action of gravity. After the tools have completely slid down into the disinfection chamber 54, the drive motor 42 rotates in the opposite direction, driving the placement plate 45 to return to a horizontal state, ready to receive the next batch of cleaned tools.

[0046] Example 2: This example is basically the same as the previous example, except that the disinfection mechanism 5 includes a disinfection box 51 and a disinfection chamber 54. The top of the disinfection box 51 is provided with a liquid inlet 52. A liquid distribution pipe 53 is connected to one side of the disinfection box 51. The end of the liquid distribution pipe 53 away from the disinfection box 51 is connected to the disinfection chamber 54. A filter screen 55 is slidably connected to the inner wall of the disinfection chamber 54. A first electric push rod 56 is fixed at the bottom of the disinfection chamber 54. The output end of the first electric push rod 56 is fixedly connected to the bottom of the filter screen 55. The disinfection box 51 is provided with a liquid pump for drawing out the disinfectant. The liquid pump is connected to the liquid distribution pipe 53.

[0047] The disinfection box 51 and disinfection chamber 54 are made of 304 stainless steel. The disinfection box 51 is used to store medical disinfectants (such as chlorine-containing disinfectants, peracetic acid solutions, etc.). Its top inlet 52 is equipped with a silicone sealing cap to prevent the disinfectant from evaporating. The dispensing tube 53 is made of chemically resistant polytetrafluoroethylene (PTFE) tubing. PTFE tubing can withstand a variety of strong corrosive disinfectants and has a long service life. The filter screen 55 is made of 304 stainless steel woven mesh with a pore size of 1-2mm, which can ensure the stable placement of the blades and allow the disinfectant to fully penetrate the blade surface. The first electric actuator 56 is a miniature electric actuator with a stainless steel shell. The surface of the actuator is chrome-plated to improve rust resistance. Its protection level reaches IP65, which can adapt to the humid and corrosive environment inside the disinfection chamber 54.

[0048] During operation, before the disinfection process starts, an appropriate amount of medical disinfectant is injected through the inlet 52 at the top of the disinfection tank 51. The pump (matching the disinfection tank 51) is powered on and runs, drawing the disinfectant into the dispensing pipe 53. The dispensing pipe 53 is evenly distributed along the top of the disinfection chamber 54, and the disinfectant is slowly injected into the disinfection chamber 54 through multiple outlets of the dispensing pipe 53 until the disinfectant level in the disinfection chamber 54 reaches the preset height. When the placement mechanism 4 delivers the blade to the filter screen 55 in the disinfection chamber 54, the first electric push rod 56 is powered on and its output end drives the filter screen 55 to slowly descend, causing the filter screen 55 to... The blades are completely immersed in the disinfectant solution. The immersion time is set according to the type of disinfectant solution and the disinfection standard (usually 10-15 minutes) to ensure that bacteria, viruses and other microorganisms on the blade surface are completely killed. After disinfection, the first electric push rod 56 reverses and drives the filter screen 55 to the middle position of the disinfection chamber 54, detaching it from the disinfectant solution surface. Then, the hot fan 72 above the clamping mechanism 7 is activated to dry the filter screen 55 and the blades. The drying temperature is controlled at 50-60 degrees Celsius to avoid damaging the blades with high temperature. The drying time is about 5-8 minutes until there is no obvious moisture on the blade surface.

[0049] In one embodiment of the present invention, the clamping mechanism 7 includes a top plate 71 fixed to the top of the inner wall of the processing box 21. A hot air fan 72 and a sliding rod 73 are fixed to the bottom of the top plate 71. A first clamping assembly 75 and a second clamping assembly 76 are slidably connected to the outer wall of the sliding rod 73. A second electric push rod 74 is fixed to one side of the inner wall of the processing box 21. The output end of the second electric push rod 74 is fixedly connected to the first clamping assembly 75. A third electric push rod 77 is fixed to the other side of the inner wall of the processing box 21. The output end of the third electric push rod 77 is fixedly connected to the second clamping assembly 76. The first clamping assembly 75 and the second clamping assembly 76 have the same structure. Component 75 includes a sliding block 7511 and a slider 751. The sliding block 7511 is slidably connected to the outer wall of the sliding rod 73. A limiting plate 7512 is provided at the bottom of the sliding block 7511. Fixed blocks 7514 are provided on both sides of the bottom of the limiting plate 7512. A sliding rod 7513 is provided between the two fixed blocks 7514. The slider 751 is slidably sleeved on the surface of the sliding rod 7513. A sixth electric push rod 7515 is provided between the side of the slider 751 and the fixed block 7514. A fourth electric push rod 752 is fixed at the bottom of the slider 751. A mounting plate 753 is fixed at the output end of the fourth electric push rod 752. Two sets of clamping parts are provided at the bottom of the mounting plate 753.

[0050] In one embodiment of the present invention, each set of clamping components includes a connecting plate 756, and two connecting plates 756 are provided. The tops of the two connecting plates 756 are fixedly connected to the mounting plate 753. A side mounting component 754 is provided on the outer side of each connecting plate 756. A fifth electric push rod 755 is fixed on one side of each side mounting component 754. A push block 759 is fixed at the output end of each fifth electric push rod 755. A rotating groove 757 is opened at the bottom of each connecting plate 756. A clamping plate 758 is rotatably connected to the inner wall of each rotating groove 757. The push block 759 is movably connected to the clamping plate 758. A clamping block 7510 is fixed at the end of each clamping plate 758 away from the rotating groove 757.

[0051] The top plate 71 is made of 304 stainless steel and is fixed to the top of the inner wall of the processing box 21, providing stable support for the entire clamping mechanism 7; the outer shell of the hot air fan 72 is made of stainless steel, and the fan blades are made of ABS engineering plastic. ABS plastic is high temperature resistant and high strength, and the heating wire is made of nickel-chromium alloy wire, which has high heating efficiency and long service life; the sliding rod 73 is a 304 stainless steel optical shaft with a finely ground surface to ensure smooth sliding; the sliding block 7511, the limiting plate 7512, the fixing block 7514, the sliding rod 7513, and the sliding... Block 751, mounting plate 753, connecting plate 756, and clamping plate 758 are all made of 304 stainless steel. Among them, the clamping block 7510 at the end of clamping plate 758 away from the rotating groove 757 is fixed with a medical-grade nitrile rubber pad. Nitrile rubber has good elasticity and strong wear resistance, which can avoid damage to the blade body when clamping the tool, and at the same time improve the clamping stability. The second, third, fourth, fifth, and sixth electric push rods 7515 are all medical-grade miniature electric push rods with stainless steel shells, IP65 protection level, and chrome-plated steel rod bodies to ensure corrosion resistance and wear resistance.

[0052] Post-cleaning transfer and disassembly: After the cleaning mechanism 3 completes the cleaning of the tool, the second electric push rod 74 and the third electric push rod 77 respectively push the first clamping assembly 75 and the second clamping assembly 76 to move along the sliding rod 73 until both clamping assemblies are directly above the cleaning chamber 35; then the sixth electric push rod 7515 is activated, pushing the slider 751 to move along the surface of the sliding rod 7513, adjusting the horizontal position of the clamping members so that the clamping members of the first clamping assembly 75 are aligned with the blade part of the tool, and the clamping members of the second clamping assembly 76 are aligned with the tool shank part of the tool; then the fourth electric push rod 752 pushes the mounting plate 753 downward, causing the clamping members to approach the tool. When the clamping members reach the preset position, the fifth electric push rod 755 is energized, and its output end pushes the push block 759. The push block 759 is movably connected to the clamping plate 758. Under the action of the push, the clamping plate 758 rotates around the pivot of the inner wall of the rotating groove 757, so that the clamping blocks 7510 at the ends of the two sets of clamping plates 758 approach each other and clamp the blade and the handle respectively. After clamping, the fourth electric push rod 752 drives the mounting plate 753 to rise, so that the blade is removed from the cleaning chamber 35. Then the second electric push rod 74 drives the first clamping assembly 75 (clamping the blade) to move away from the second clamping assembly 76 (clamping the handle) until the blade and the handle are completely separated. Finally, the two sets of clamping assemblies move to the top of the placement mechanism 4, the fifth electric push rod 755 runs in the opposite direction, the clamping block 7510 is released, and the separated blade and handle fall on the placement plate 45, completing the transfer and disassembly.

[0053] After disinfection and drying, the blade is assembled and stored: After the disinfection mechanism 5 completes the disinfection and drying of the blade, the first clamping component 75 and the second clamping component 76 move again above the disinfection chamber 54 and clamp the blade and the handle respectively. Then the two clamping components move closer to each other and precisely assemble the blade and the handle. After assembly, the clamping mechanism 7 moves the complete blade to the storage mechanism 8, releases the clamping block 7510, and puts the blade into the storage mechanism 8 to complete the assembly and storage.

[0054] Example 3: This example is basically the same as the previous example, except that the storage mechanism 8 includes a support block 81 fixed to the inner wall of the processing box 21. A first placement component 82 and a second placement component 83 are fixed to the top of the support block 81. The first placement component 82 is used to store the handle of the pathological sampling knife, and the second placement component 83 is used to store the blade of the pathological sampling knife. The first placement component 82 includes a first placement block 821. A first placement groove 822 is opened on the top of the first placement block 821. A first compression clamping member 823 is slidably connected to the inner wall of the first placement groove 822. A first spring 824 is fixed on one side. The end of the first spring 824 away from the first compression clamp 823 is fixedly connected to the inner wall of the first placement groove 822. The second placement assembly 83 includes a second placement block 831. A second placement groove 832 is opened on the top of the second placement block 831. A baffle 833 is fixed on the inner wall of the second placement groove 832. A second compression clamp 834 is slidably connected to the inner wall of the second placement groove 832. A second spring 835 is fixed on one side of the second compression clamp 834. The end of the second spring 835 away from the second compression clamp 834 is fixedly connected to the inner wall of the second placement groove 832.

[0055] The support block 81 is made of 304 stainless steel and is fixed to the inner wall of the processing box 21 by bolts to provide stable support for the placement components. The placement blocks of the first placement component 82 and the second placement component 83 are both made of 304 stainless steel and the surface is polished. The first extrusion clamping member 823 and the second extrusion clamping member 834 are made of stainless steel, and their surfaces in contact with the blade are fixed with medical-grade silicone rubber pads to avoid scratching the blade or causing contamination. The first spring 824 and the second spring 835 are stainless steel springs. Stainless steel springs are corrosion-resistant, have long-lasting elasticity, and can maintain a stable clamping force for a long time. The baffle 833 is a thin 304 stainless steel plate and is fixed to the inner wall of the second placement groove 832 by welding to limit the position of the blade.

[0056] The storage mechanism 8 is divided into a first placement component 82 (for storing the knife handle) and a second placement component 83 (for storing the blade). The two components work on the same principle: when the clamping mechanism 7 transports the assembled knife or the disassembled knife handle and blade to the storage mechanism 8, the knife (or knife handle, blade) is placed in the corresponding placement slot (the first placement slot 822 holds the knife handle, and the second placement slot 832 holds the blade). During placement, the knife squeezes the clamping component, causing the clamping component to slide along the inner wall of the placement slot, while simultaneously compressing a spring on one side. The spring generates a reverse elastic force during compression, pushing the clamping component to firmly press against the knife, fixing the knife in the placement slot. For the second placement slot 832, the baffle 833 on the inner wall can further restrict the position of the blade, preventing the blade from shifting laterally during storage. When the knife needs to be retrieved, the operator only needs to open the door 6 on one side of the processing box 21 and gently pull the knife outward to overcome the spring force and remove the knife. After retrieval, the clamping component resets under the action of the spring, waiting for the next storage.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
