Description

Technical Field

[0001] This invention relates to an eccentric surging structure and a surgical instrument soaking and rinsing pretreatment device. It belongs to the field of surgical instrument cleaning technology, and specifically relates to an eccentric surging structure that uses a rotary motor to drive a fixed gear to rotate, and then uses an eccentric gear and a connecting rod to make the cleaning tray slide around a circle, thereby causing the surgical instruments to sway and clean in water. 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 to prevent collision damage by a buffer component, and removes surface dirt by using a rinsing component. However, the up-and-down vibration mechanism of this device during instrument cleaning poses a risk of damaging the instruments. Surgical instruments are often delicate in structure and made of special materials, making them extremely sensitive to impacts and vibrations. During this vibration, instruments are prone to violent collisions with the cleaning tray or other equipment, potentially causing chipped blades, instrument deformation, and loosening of connections. This not only reduces the precision and sharpness of the instruments but also affects their lifespan and safety. Furthermore, frequent vibration can cause displacement or damage to tiny internal parts of some precision surgical instruments, affecting their normal function. Long-term use of this cleaning method increases instrument wear and tear and raises medical costs. Summary of the Invention

Detailed Implementation Example 1

[0013] The eccentric surging structure and surgical instrument soaking and rinsing pretreatment device of the present invention are implemented as follows: The eccentric surging structure of the present invention consists of a frame (31), a rotary motor (34), a fixed gear (36), a second connecting rod (30), a third connecting rod (32), a first connecting rod (29), a fixed pin (37), a fourth connecting rod (33), and an eccentric gear (35). The side of the stand (31) is in contact with the inner side of the cleaning tank (3) in the surgical instrument soaking and rinsing pretreatment device. The rotary motor (34) is fixedly placed on the bottom surface of the support frame (31). A fixed gear (36) is placed on a support frame (31). The axle of the fixed gear (36) passes through the support frame (31) and is fixedly connected to the shaft of a rotary motor (34). A sealed bearing is placed between the axle of the fixed gear (36) and the support frame (31). One end of the second connecting rod (30) is rotatably connected to the top surface of the upright (31). One end of the third link (32) is rotatably connected to the top surface of the upright (31). One end of the first link (29) is rotatably connected to the other end of the second link (30) via a fixing pin (37), and the other end of the first link (29) is rotatably connected to the other end of the third link (32) via a fixing pin (37). One end of the fourth link (33) is fixedly connected to the middle side of the first link (29), and one end of the fourth link (33) is perpendicular to the middle of the first link (29). The other end of the fourth link (33) is fixedly connected to the outer side of the eccentric gear (35). Preferably, the first link (29), the second link (30), the third link (32), and the fourth link (33) all adopt a hollow tubular structure, and the first link (29), the second link (30), the third link (32), and the fourth link (33) are made of carbon fiber composite material. The inner surface of the eccentric gear (35) has multiple teeth arranged at equal intervals along the circumference of the eccentric gear (35), and the eccentric gear (35) meshes with the fixed gear (36). The bottom surface of the cleaning tray (2) is fixedly connected to the top surface of the eccentric gear (35), and the central axis of the eccentric gear (35) is close to the center of the bottom surface of the cleaning tray (2). Preferably, the cleaning tray (2) is made of carbon fiber composite material. Preferably, the height of the top surface of the eccentric gear (35) is higher than the height of the fixed gear (36) to avoid contact between the cleaning tray (2) and the fixed gear (36). Preferably, the thickness of the eccentric gear (35) is greater than the thickness of the fixed gear (36) to improve meshing stability. 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 rotary motor (34) is driven. The rotary motor (34) drives the fixed gear (36) to rotate together, and the eccentric gear (35) meshing with it also moves. At the same time, the first link (29), the second link (30), the third link (32) and the fourth link (35) move together. Under the coordinated action of the four-bar linkage (33), the eccentric gear (35) will make eccentric motion around the fixed gear (36). Since the bottom surface of the cleaning tray (2) is fixedly connected to the top surface of the eccentric gear (35), and the central axis of the eccentric gear (35) is close to the center of the bottom surface of the cleaning tray (2), the movement of the eccentric gear (35) will drive the cleaning tray (2) and the surgical instruments in the cleaning tray (2) to slide eccentrically together, so that the cleaning fluid impacts the surgical instruments from multiple angles, thereby enhancing the removal effect of stains on the surgical instruments. After cleaning, the cleaning fluid is discharged through the drain pipe (5). When the height of the cleaning fluid is much lower than the surgical instruments, the water pump (7) is started again, and the cleaning fluid 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.

[0014] The design of the side of the support frame (31) fitting against the inner side of the cleaning tank (3) ensures that the support frame has a stable installation position in the cleaning tank (3), reduces the shaking of the support frame caused by vibration and other factors during the operation of the device, improves the stability of the entire eccentric rotating structure, and prevents the cleaning liquid from seeping into the bottom of the support frame (31) and damaging the rotating motor (34). The design of a sealed bearing between the fixed gear (36) axle and the upright (31) can prevent cleaning fluid, impurities, etc. from entering below the upright (31), avoid damage to the rotary motor (34) due to contamination, extend the service life of the rotary motor (34), and at the same time, the sealed bearing can also reduce the friction between the bearing and the upright, reduce noise, and improve the stability of the device operation. The first link (29), the second link (30), the third link (32), and the fourth link (33) all adopt a hollow tubular structure design, which can significantly reduce the weight of the link, thereby reducing the load of the entire eccentric rotating structure and reducing the energy consumption of the rotating motor. The first link (29), the second link (30), the third link (32) and the fourth link (33) are made of carbon fiber composite material, which has the advantages of high strength, low density, corrosion resistance and fatigue resistance. The high strength enables the link to withstand large tensile and compressive forces, ensuring that it will not deform or break during eccentric rotation. The low density further reduces the weight of the link. The corrosion resistance makes the link less susceptible to corrosion in the cleaning fluid environment, thus extending its service life. The design of the bottom surface of the cleaning tray (2) being fixedly connected to the top surface of the eccentric gear (35) and the central axis being close to coincide ensures that the cleaning tray (2) moves accurately following the movement of the eccentric gear (35), so that the surgical instruments in the cleaning tray (2) can obtain a stable and effective eccentric rotation cleaning effect. The close coincidence of the central axis can reduce the shaking and displacement of the cleaning tray (2) during the movement, and improve the uniformity and stability of the cleaning. The purpose is to achieve the goal of rotating the fixed gear (36) through the rotary motor (34), and then linking it with the connecting rod through the eccentric gear (35) to make the cleaning tray (2) slide around a circle, thereby driving the surgical instruments to shake and clean in the water.

[0015] It should be noted that the eccentric rotating structure needs to be installed in the following surgical instrument soaking and rinsing pretreatment device; This invention discloses a surgical instrument soaking and rinsing pretreatment device, comprising a soaking component, a rinsing component, a flow component, and two sets of buffer components.

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

[0016] 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

[0017] 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.
