Description

Technical Field

[0001] This invention relates to a reciprocating brushing structure and a surgical instrument soaking and rinsing pretreatment device. It relates to a brushing structure installed on a surgical instrument soaking and rinsing pretreatment device, belonging to the field of surgical instrument cleaning technology. In particular, it relates to a brushing structure that uses a driving and adjusting motor to make a cylindrical slider slide in a circular motion, pushing the cleaning tray and the surgical instruments inside to rise and fall along the slide rail. Through spring buffering and shock absorption, water flows reciprocally through the drain hole at the bottom of the cleaning tray to achieve brushing of the surgical instruments. Background Technology

[0002] In the field of surgical instrument pretreatment, existing soaking and rinsing pretreatment technologies have many problems that urgently need to be solved. The current mainstream methods are simple soaking and simple rinsing. Simple soaking relies solely on the chemical action of the cleaning solution to soften residual stains on the instruments. This process is slow and inefficient, and it is difficult to achieve the desired softening effect on stubborn stains. Furthermore, the poor fluidity of water cannot create multi-angle impacts on the instruments, making it impossible to fully remove stains. Simple rinsing, on the other hand, is often a static water flow that cannot penetrate the complex structure and crevices of surgical instruments, resulting in poor cleaning of residual stains inside the instruments and incomplete pretreatment. In addition, during the cleaning process, due to the lack of cushioning measures, surgical instruments are prone to significant vibrations within the device, leading to collisions, damage to the instruments, and affecting their service life and performance.

[0003] Publication number CN117798119B discloses a surgical instrument cleaning box, including a cleaning box body, a rotating structure on the inner side of the cleaning box body, a cleaning structure inside the cleaning box body, a sealing structure on the top side of the cleaning box body, a positioning structure connected to the rotating structure, a disinfection structure on the side of the cleaning box body, and a moving structure connected to the bottom side of the cleaning box body. The rotating structure improves the cleaning effect, the cleaning structure allows for more comprehensive cleaning of surgical instruments, the sealing structure facilitates sealing of the cleaning box body to prevent water splashing during cleaning, the positioning structure ensures that the basket does not shift during the cleaning of medical instruments, and the disinfection structure allows for rapid disinfection of the cleaned surgical instruments. However, the above-mentioned surgical instrument cleaning equipment, due to the large amplitude of water flow agitation, is prone to collisions between instruments and between instruments and equipment, which may lead to wear on the surface of metal instruments and deformation of precision parts. Furthermore, the metal fragments, plastic particles, and fibers generated by the collisions can exacerbate the risk of cross-contamination, and the worn equipment parts can shorten their service life and increase maintenance costs.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "A Surgical Instrument Immersion and Rinse Pretreatment Device." This device softens instrument stains through an immersion component to prepare for subsequent cleaning, enhances the immersion effect by using a flow component to drive water flow, reduces instrument vibration and prevents collision damage by a buffer component, and removes surface dirt by using a rinsing component. However, when the surgical instruments are raised to a higher position on the cleaning tray, the device is prone to brief jerks, causing the instruments to be jolted. Since surgical instruments are typically quite delicate, the impact force from these jerks may damage their internal structure, affecting their normal performance and lifespan.

Detailed Implementation Example 1

[0012] The reciprocating brushing structure of the present invention comprises a base plate (36), a slide rail (31), a slider (30), a spring (33), a slide groove (32), a stand (34), an adjusting motor housing (37), a turntable (38), a connecting rod (39), a connecting shaft (35), and a cylindrical slider (40). The base plate (36) is fixedly placed on the base (13) of a surgical instrument soaking and rinsing pretreatment device. The slide rail (31) is fixedly placed on the top surface of the base plate (36). There are two slide rails (31), which are respectively arranged close to two opposite sides of the base plate (36) and are located in the middle of the width direction of the side. Preferably, the cross-section of the slide rail (31) is designed as a dovetail groove. The two ends of the slider (30) are slidably connected to the two slide rails (31) respectively. One end of the spring (33) is fixedly connected to the middle of the top surface of the base plate (36), and the other end of the spring (33) is fixedly connected to the middle of the bottom surface of the slider (30). Preferably, the spring (33) is made of shape memory alloy and its surface is coated with a corrosion-resistant nano-ceramic coating. The slider (30) has a groove (32) on one side. The upright (34) is fixedly placed on the top surface of the base plate (36), and the upright (34) is placed between two slide rails (31). Adjust the motor housing (37) and the upright frame (34) for fixed connection. Preferably, the regulating motor housing (37) is made of stainless steel with good sealing performance, and is equipped with sound insulation cotton and heat dissipation fins inside. The axle of the turntable (38) passes through the upright (34) and the adjusting motor housing (37) and is fixedly connected to the adjusting motor shaft inside the adjusting motor housing (37). A sealed bearing is placed between the turntable (38) and the upright (34) and the adjusting motor housing (37). One end of the connecting rod (39) is fixedly connected to the side of the turntable (38). One end of the connecting shaft (35) is fixedly connected to the side of the connecting rod (39) near the other end. The other end of the connecting shaft (35) is rotatably connected to a cylindrical slider (40), and the cylindrical slider (40) is slidably connected to the slider (30) through a groove (32). Preferably, the surface of the cylindrical slider (40) is provided with a plurality of ball bearings, and is made of high-strength engineering plastic material. One end of the fixed connecting block (29) is fixedly connected to the middle of the top surface of the slider (30), and the other end of the fixed connecting block (29) is fixedly connected to the middle of the bottom surface of the cleaning tray (2). When in use, start the adjusting motor inside the adjusting motor housing (37). The motor shaft drives the turntable (38) fixedly connected to it to start rotating. As the turntable (38) rotates, the connecting rod (39) fixedly connected to it also slides in a circle around the central axis of the turntable (38). During the movement, the connecting rod (39) drives the connecting shaft (35) and the cylindrical slider (40) rotatably connected to the connecting shaft (35) to slide in a circle together. The ball bearings on the surface of the cylindrical slider (40) make it slide more smoothly in the slide groove (32). During the circular sliding process of the cylindrical slider (40), its height will change continuously. When the height of the cylindrical slider (40) rises, it will push the slider (30) to slide upward along the slide rail (31), and the spring (33) will be stretched. The downward pulling force is generated. When the height of the cylindrical slider (40) drops, the spring (33) is compressed and releases the upward thrust. The force generated by its stretching and contraction plays a buffering role on the slider (30), reducing the impact force of the slider (30) falling rapidly due to its own weight, the weight of the cleaning tray (2) and the surgical instruments, and achieving smooth lifting and lowering. Since the slider (30) is connected to the cleaning tray (2) through the fixed connecting block (29), the lifting and lowering of the slider (30) drives the cleaning tray (2) and the surgical instruments in the cleaning tray (2) to lift and lower synchronously. Since the slider (30) is connected to the cleaning tray (2) through the fixed connecting block (29), the lifting and lowering of the slider (30) drives the cleaning tray (2) and the surgical instruments in the cleaning tray (2) to lift and lower synchronously. The spring (33) is made of memory alloy and coated with nano-ceramic coating. It can not only maintain stable elastic performance in different environments, but also has anti-corrosion ability, ensuring stable operation during the cleaning process. It effectively reduces the sudden stress generated when the cleaning tray (2) is raised and lowered to the top and bottom, avoiding damage to the surgical instruments. During the continuous raising and lowering of the cleaning tray (2), the water flow can pass through the drain hole (4) at the bottom of the cleaning tray (2) repeatedly. This reciprocating flow of water can thoroughly rinse the surgical instruments in the cleaning tray (2), washing away the dirt on the surface of the surgical instruments, thereby achieving efficient cleaning of the surgical instruments. The slide rail (31) is designed with a dovetail groove shape in its cross section. The unique design of the dovetail groove shape allows the slider (30) to be restricted by both sides of the dovetail groove when sliding in the slide rail (31), effectively preventing the slider (30) from derailing and ensuring the stability and accuracy of the sliding process. One end of the spring (33) is fixedly connected to the middle of the top surface of the base plate (36), and the other end of the spring (33) is fixedly connected to the middle of the bottom surface of the slider (30). The spring (33) is made of memory alloy material and coated with a corrosion-resistant nano-ceramic coating. The memory alloy material gives the spring (33) stable elastic performance in different working environments and has a certain self-repairing ability, which effectively extends the service life of the spring (33). The nano-ceramic coating is designed to prevent the cleaning fluid from corroding the spring (33) in the humid environment during the cleaning process, ensuring that the spring (33) always maintains good elasticity and mechanical properties during long-term use, stably providing buffer and assistance for the lifting and lowering of the slider (30), reducing the sudden stress generated when the cleaning tray (2) is lifted to the top and bottom, and avoiding damage to the surgical instruments. The regulating motor housing (37) is made of stainless steel with good sealing performance. The design of sound insulation cotton and heat dissipation fins inside effectively prevents cleaning fluid from entering the motor housing, protects the regulating motor from liquid corrosion, and extends the service life of the motor. The sound insulation cotton inside can effectively reduce the noise generated when the regulating motor is working, creating a quieter working environment for the operator. The heat dissipation fins significantly enhance the heat dissipation effect of the regulating motor, prevent the motor from being damaged due to overheating, and ensure that the regulating motor maintains a stable working state during long-term, high-load operation, thereby improving the working efficiency and reliability of the motor. The cylindrical slider (40) can be made to slide in a circular motion by driving the adjustment motor, which pushes the cleaning tray (2) and the surgical instruments inside to rise and fall along the slide rail (31). The spring (33) buffers and dampens the shock, so that the water flows through the drain hole (4) at the bottom of the cleaning tray (2) to achieve the purpose of rinsing the surgical instruments.

[0013] It should be noted that the reciprocating rinsing structure needs to be installed in one of the surgical instrument soaking and rinsing pretreatment devices, and a part of the structure in the surgical instrument soaking and rinsing pretreatment device needs to be replaced during the installation process. The surgical instrument soaking and rinsing pretreatment device of the present invention is implemented as follows: The surgical instrument soaking and rinsing pretreatment device of the present invention includes a soaking component, a rinsing component, a flow component, and two sets of buffer components. The features include: the rinsing assembly and the soaking assembly are connected; the gushing assembly is placed inside the soaking assembly; the two sets of buffer assemblies are placed between the base (13) and the cleaning tray (2); the soaking assembly soaks and softens residual stains on the medical instruments; the rinsing assembly rinses the surgical instruments on the cleaning tray (2) with running water; the gushing assembly drives the flow of water to the instruments; and the buffer assemblies reduce the vibration of the surgical instruments on the cleaning tray (2) to avoid collision damage. The soaking assembly consists of a cleaning tank (3) and a drain pipe (5). The top of the cleaning tank (3) is open. Preferably, the inner wall of the cleaning tank (3) is made of smooth ceramic material. The drain pipe (5) is fixedly connected to the side of the cleaning tank (3) near the bottom end, and the drain pipe (5) is connected to the cleaning tank (3). The flushing assembly consists of a water tank (6), a water pump (7), a water pipe (8), and a water tap (1). The water storage tank (6) is fixedly connected to the outer side of the cleaning tank (3). The water pump (7) is fixedly placed on the water storage tank (6), and the inlet of the water pump (7) is connected to the outlet of the water storage tank (6). One end of the water pipe (8) is connected to the outlet of the water pump (7), and the other end of the water pipe (8) is placed inside the cleaning tank (3), and is positioned near the top of the cleaning tank (3) in the vertical direction and in the middle of the cleaning tank (3) in the horizontal direction. The other end of the water pipe (8) is spirally connected to a water tap (1). Preferably, the nozzle of the water tap (1) is an adjustable rotating nozzle, and the nozzle surface has multiple small protrusions. The surge assembly consists of a base (13), a waterproof motor housing (12), a drive shaft (22), a second roller (23), a connecting disc (24), a connecting rod (14), a first roller (15), a U-shaped connector (16), a first connecting sleeve (17), a second connecting sleeve (18), a sleeve metal connector (19), a cleaning tray (2), a drain hole (4), a rubber plug (26), and a thin spring (21). The base (13) is placed on the bottom surface of the cleaning tank (3), and the base (13) is a hollow structure. The waterproof motor housing (12) is fixedly connected to one outer side of the base (13), and is located in the middle of the width direction of that side. The drive shaft (22), the second roller (23), the connecting disc (24), and one end of the connecting rod (14) are placed inside the base (13). Two drive shafts (22) are provided. The two drive shafts (22) are rotatably connected to the two opposite sides of the base (13) near one end, and are provided with supporting bearings. One end of one of the drive shafts (22) is fixedly connected to the motor shaft of the motor inside the waterproof motor housing (12). A connecting disc (24) is fixedly placed at the other end of the drive shaft (22) and connected to the middle of the connecting disc (24). The connecting disc (24) corresponds one-to-one with the drive shaft (22) and is placed between the two drive shafts (22). The two ends of the second roller (23) are rotatably connected to the two connecting discs (24) near their sides. The second roller (23) is arranged parallel to the drive shaft (22). One end of the connecting rod (14) is fixedly connected to the side of the second roller (23). The base (13) has a through hole at the top center. The inner side of an elastic waterproof ring is fixedly connected to the middle side of the connecting rod (14), and the outer side is fixedly connected to the side of the through hole of the base (13). The other end of the connecting rod (14) is fixedly connected to the side of the first roller (15). The top of the U-shaped connector (16) has a limiting groove (25). The first roller (15) is placed inside the U-shaped connector (16), and its two ends are rotatably connected to the two vertical plates of the U-shaped connector (16). One end of the first connecting sleeve (17) is fixedly connected to the top surface of the U-shaped connector (16) and communicates with the limiting groove (25). The second connecting sleeve (18) is fitted onto the first connecting sleeve (17) and is slidably connected to the first connecting sleeve (17). The top end of the second connecting sleeve (18) is fixed with a sleeve metal connector (19), which is a hollow structure. The bottom center of the cleaning tray (2) is fixedly connected to the sleeve metal connector (19), and the top of the cleaning tray (2) is an open structure. The bottom surface of the cleaning tray (2) has multiple drainage holes (4) evenly distributed. Preferably, the inner bottom surface of the cleaning tray (2) has a wavy structure. One end of the connecting rod (20) is placed inside the sleeve metal connector (19), and the other end of the connecting rod (20) extends vertically downward through the sleeve metal connector (19) and is placed inside the first connecting sleeve (17). The connecting rod (20) and the sleeve metal connector (19) are slidably connected. A rubber plug (26) is placed at each end of the connecting rod (20). A thin spring (21) is wound around the side of the connecting rod (20). Preferably, the thin spring (21) is made of high-strength stainless steel. The buffer assembly consists of a first metal connector cylinder (9), a second metal connector cylinder (11), and a coarse spring (10). The top of the first metal connector cylinder (9) is fixedly connected to the bottom of the cleaning tray (2). The bottom end of the second metal connector cylinder (11) is fixedly connected to the top surface of the base (13). One end of the coarse spring (10) is fixedly connected to the bottom surface of the cleaning tray (2) and placed inside the first metal connector cylinder (9). The other end of the coarse spring (10) is fixedly connected to the top surface of the base (13) and placed inside the second metal connector cylinder (11). Preferably, the coarse spring (10) is made of high-strength stainless steel. When in use, the surgical instruments are placed in the cleaning tray (2), the water pump (7) is started, and the cleaning solution in the water tank (6) is drawn out. The cleaning solution flows through the water pipe (8) and sprays out from the water tap (1) to rinse the surgical instruments with running water. Since the nozzle of the water tap (1) is adjustable and has small protrusions on its surface, it can disperse the water flow into a finer water jet, expanding the rinsing range. The rinsed cleaning solution flows into the cleaning tank (3). As the cleaning solution accumulates and submerges the surgical instruments, the instruments begin to be soaked. When the cleaning solution submerges the instruments, the waterproof motor housing (12) is started, driving the drive shaft (22) connected to it to rotate, which in turn causes the connecting disc (24) connected to the drive shaft (22) to rotate, causing the second roller (23) to make a circular motion around the central axis of the drive shaft (22). The second roller (23) drives the U-shaped connector (16) to rise and fall through the connecting rod (14). The type connector (16) is connected by the sliding connection of the first connecting sleeve (17) and the second connecting sleeve (18), which drives the sleeve metal connector (19) and the cleaning tray (2) to move up and down. The wave-shaped structure at the bottom of the cleaning tray (2) combined with its up and down movement activates the water flow in the cleaning tank (3) to form a surge, which impacts the surgical instruments from multiple angles and enhances the stain removal effect. Throughout the process, the thin spring (21) and the thick spring (10) jointly absorb the vibration of the cleaning tray (2) during movement, reducing instrument collision damage. After cleaning, the cleaning liquid is discharged through the drain pipe (5). When the height of the cleaning liquid is much lower than the surgical instruments, the water pump (7) is started again, and the cleaning liquid is sprayed from the water tap (1) to rinse the surgical instruments a second time, so as to avoid impurities adsorbing on the surgical instruments. Example 2

[0014] The difference between this embodiment and embodiment 1 is that the bottom surface of the cleaning box (3) is provided with a shock-absorbing pad (27). When in use, the shock-absorbing pad (27) can effectively reduce the transmission of vibration, avoid the internal structure of the cleaning box from becoming loose and the parts from being worn due to excessive vibration, extend the service life of the equipment, and at the same time reduce the noise generated during the operation of the equipment, reduce the interference to the operators and the surrounding environment. Example 3

[0015] The difference between this embodiment and embodiment 1 is that a sealing ring (28) is placed between the drain pipe (5) and the cleaning tank (3). When in use, it can effectively fill the gap at the connection between the drain pipe (5) and the cleaning tank (3), prevent the cleaning liquid from leaking, reduce the pollution or corrosion to the external structure of the equipment and the surrounding environment, and extend the service life of the device. The inner wall of the cleaning tank (3) is made of smooth ceramic material. Ceramic material has excellent corrosion resistance and anti-adhesion properties, which can prevent cleaning liquid residue and stains from adhering, reduce the risk of bacterial growth, and at the same time, the smooth surface reduces water flow resistance and can improve the cleaning liquid circulation efficiency. The other end of the water pipe (8) is placed inside the cleaning tank (3) and is positioned close to the top of the cleaning tank (3) in the height direction and in the middle of the cleaning tank (3) in the horizontal direction. This design utilizes gravitational potential energy to increase the impact force, strengthen the removal of stubborn stains on the surface of the instruments, and ensure that the water flow is evenly diffused in all directions to avoid the shadow area of ​​the instruments caused by unilateral rinsing. It is especially suitable for scenarios where multiple rows of instruments are cleaned at the same time. The inner bottom surface of the cleaning tray (2) is designed with a wave-shaped structure. The wave-shaped surface increases the contact area between the water flow and the equipment, and enhances the soaking effect. During the lifting and lowering process of the cleaning tray (2), the wave structure cuts the water flow to form turbulence and enhances the impact force of the surging flow. The design of the thick spring (10) with one end fixedly connected to the bottom surface of the cleaning tray (2) and the other end fixedly connected to the top surface of the base (13) can absorb low-frequency large-amplitude vibrations. Both the coarse spring (10) and the fine spring (21) are made of high-strength stainless steel, which has strong corrosion resistance and is suitable for chemical cleaning solutions in medical environments. At the same time, it extends the service life of the spring and reduces the frequency of replacement. The base (13) has a through hole at the top center. The inner side of an elastic waterproof ring is fixedly connected to the middle side of the connecting rod (14), and the outer side is fixedly connected to the through hole side of the base (13). This design can prevent water from entering the base, protect the internal components of the base (13), and extend the service life. The system aims to soften stains on instruments through the soaking component, prepare them for subsequent cleaning, enhance the soaking effect by driving water flow through the surging component, reduce instrument vibration and prevent collision damage through the buffer component, and remove surface dirt by rinsing the instruments with running water through the rinsing component.
