Description

Technical Field

[0001] This invention relates to a lifting and draining structure and a surgical instrument soaking and rinsing pretreatment device. It describes a structure installed on a surgical instrument soaking and rinsing pretreatment device that lifts surgical instruments out of the water surface. It belongs to the field of surgical instrument cleaning technology, and specifically relates to a lifting and draining structure that uses an electric push rod to drive a connected transmission rod upwards. The rotation of the second and first connecting plates in the lifting assembly pushes the base and cleaning tray upwards, achieving the function of lifting and draining surgical instruments out of the water surface, while also facilitating the recycling of cleaning fluid. 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 to rinse the instruments with running water. However, this surgical instrument cleaning equipment faces a dilemma after cleaning. If the cleaning solution is poured out to remove the surgical instruments, the cleaning solution needs to be refilled for the next cleaning, undoubtedly wasting the solution. On the other hand, if hands are immersed in the cleaning solution to retrieve the surgical instruments, it may contaminate the cleaning solution, affecting the subsequent cleaning effect, and the cleaning solution may also cause injury to the hands.

Detailed Implementation Example 1

[0013] The present invention provides a drainage lifting structure comprising a base plate (29), two sets of connecting components, two sets of lifting components, and a transmission component. The feature is that the two sets of connecting components, the two sets of lifting components, and the transmission components are all placed between the base plate (29) and the cleaning tray (2). In each set of connecting components, two fixing plates (32) are respectively fixedly connected to the top surface of the base plate (29) and the bottom surface of the base (13), and are positioned near one side of the base plate (29). The two sets of connecting components are respectively positioned near the two sides of the base plate (29). The connecting components correspond one-to-one with the lifting components, and the transmission components are connected to the lifting components. The base plate (29) is fixedly placed on the bottom surface inside the cleaning tank (3) and positioned between the cleaning tank (3) and the base (13). The connecting assembly consists of a fixed plate (32) and a sliding groove (31). Each of the connecting components has two fixing plates (32), one of which is fixedly connected to the top surface of the base plate (29), and the other of which is fixedly connected to the bottom surface of the base (13). Preferably, the fixing plate (32) is made of high-strength aluminum alloy and the surface is anodized. Each of the fixed plates (32) has a groove (31). The lifting assembly consists of a second connecting plate (36), a fixing pin (34), a sliding block (35), and a first connecting plate (33). The second connecting plate (36) has a fixing pin (34) on one side near one end. The second connecting plate (36) has a sliding block (35) on one side near the other end. Preferably, the surface of the sliding block (35) is inlaid with a polytetrafluoroethylene coating. One end of the second connecting plate (36) is rotatably connected to the lower fixed plate (32) via a fixing pin (34), and the sliding block (35) at the other end of the second connecting plate (36) is slidably connected to the upper fixed plate (32) via a sliding groove (31). The first connecting plate (33) has a fixing pin (34) on one side near one end. A sliding block (35) is placed on one side of the first connecting plate (33) near the other end. One end of the first connecting plate (33) is rotatably connected to the upper fixed plate (32) via a fixing pin (34), and the sliding block (35) at the other end of the first connecting plate (33) is slidably connected to the lower fixed plate (32) via a sliding groove (31). The first connecting plate (33) and the second connecting plate (36) are rotatably connected at the middle by a rotating shaft. The transmission assembly consists of a transmission rod (30), a fixed collar (37), a connecting plate (39), and an electric actuator (38). The transmission rod (30) is provided in two sets, and each set of the transmission rod (30) has two rods. Preferably, the transmission rod (30) is made of stainless steel and has spiral reinforcing ribs on its body. One set of the transmission rods (30) is fixedly connected to the second connecting plate (36), and one end of the transmission rod (30) in this set is fixedly connected to one end of each of the two second connecting plates (36), while the other end of the transmission rod (30) is fixedly connected to the other end of each of the two second connecting plates (36). Another set of transmission rods (30) are fixedly connected to the first connecting plate (33), and one of the transmission rods (30) in this set is fixedly connected at both ends to one end of the two first connecting plates (33), and the other transmission rod (30) is fixedly connected at both ends to the other end of the two first connecting plates (33). The fixing collar (37) is fitted onto the middle side of the transmission rod (30) which is fixedly connected to one end of the first connecting plate (33), and is rotatably connected to the transmission rod (30). Preferably, the retaining collar (37) is made of brass and has a rolling bearing inside. The connecting plate (39) is fixedly placed on the base plate (29). One end of the electric actuator (38) is rotatably connected to the connecting plate (39), and the other end is fixedly connected to the fixing collar (37). Preferably, the surface of the electric actuator (38) is provided with a waterproof coating. When in use, after the surgical instruments have been cleaned, and it is necessary to lift the surgical instruments in the cleaning tray (2) out of the water for retrieval, the electric push rod (38) is activated, which drives the fixed collar (37) fixedly connected to it to rise. The rise of the fixed collar (37) will drive the transmission rod (30) connected to it to rise synchronously. As the transmission rod (30) rises, the first connecting plate (33) and the second connecting plate (36) fixedly connected to the transmission rod (30) begin to move. One end of the second connecting plate (36) is rotatably connected to the lower fixed plate (32) through the fixed pin (34), and the sliding block (35) at the other end slides in the groove (31) of the fixed plate (32). As the transmission rod (30) rises, the angle between the first connecting plate (33) and the second connecting plate (36) gradually increases, thereby pushing the base (13) to rise, which in turn drives the cleaning tray (2) to rise, so that the surgical instruments are lifted out of the water. When the electric push rod (38) pushes the transmission component to lift the cleaning tray (2) to a suitable height, the operator can easily take the surgical instruments, avoiding the operator from putting their hands into the cleaning solution. This not only prevents the cleaning solution from being contaminated, but also ensures the safety of the operator. At the same time, after taking the cleaned surgical instruments, it is convenient to put the uncleaned surgical instruments back in, so as to realize the recycling of the cleaning solution. Each of the fixed plates (32) has a groove (31) designed to provide a sliding track for the sliding block (35). The groove (31) design enables the lifting assembly to move up and down according to a predetermined trajectory, which plays a good guiding role and ensures the stability and accuracy of the lifting process of the cleaning tray (2). The second connecting plate (36) and the first connecting plate (33) are rotatably connected in the middle by a rotating shaft, and one end of each is rotatably connected to the fixed plate (32) by a fixing pin (34). The sliding block (35) at the other end slides in the groove (31) of the fixed plate (32). This design allows the connecting plate to flexibly change the included angle under the drive of the transmission rod (30), thereby effectively pushing the base (13) to rise. At the same time, the rotational connection and sliding connection reduce the resistance during the movement, making the lifting process smoother and improving the operating efficiency of the device. The sliding block (35) is inlaid with a polytetrafluoroethylene coating. Polytetrafluoroethylene has an extremely low coefficient of friction, which greatly reduces the friction between the sliding block (35) and the groove (31), making the sliding process smoother and reducing energy loss. In addition, the polytetrafluoroethylene coating also has good wear resistance and corrosion resistance, which extends the service life of the sliding block (35) and ensures the long-term stable operation of the lifting assembly. The transmission rod (30) is made of stainless steel and has a spiral reinforcing rib design. The stainless steel material ensures that the transmission rod (30) has high strength and corrosion resistance, and can stably transmit power in a humid environment. The spiral reinforcing rib further enhances the strength and deformation resistance of the transmission rod (30), making it less likely to bend or break when subjected to large tensile and compressive forces, thus ensuring the stability and reliability of power transmission. The electric actuator (38) drives the connected transmission rod (30) to rise, and the rotation of the second connecting plate (36) and the first connecting plate (33) in the lifting assembly pushes the base (13) and the cleaning tray (2) to rise, thereby realizing the function of lifting surgical instruments out of the water and draining water, while facilitating the recycling of cleaning fluid.

[0014] It should be noted that the aforementioned drainage structure needs to be installed in one of the following surgical instrument soaking and rinsing pretreatment devices; 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.

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 inside 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

[0015] 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

[0016] 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) having 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.
