Description

Technical Field

[0001] The invention relates to the technical field of medical appliance cleaning, and in particular to a cystoscope cleaning system for urology surgery. Background Art

[0002] A cystoscope is a type of endoscope, which is mainly composed of a speculum, an intubation scope, an obturator, a sheath, etc. The cystoscope needs to be effectively cleaned before use to prevent cross infection. During cleaning, a cleaning device is often used to supply cleaning fluid from the cystoscope connection to the cystoscope pipeline to clean the inside of the cystoscope pipeline. However, it is difficult to remove tissue debris attached to the inner wall of the cystoscope pipeline by relying solely on cleaning fluid.

[0003] The patent document with the publication number CN114831588A discloses a cystoscope cleaning system for urology. In the initial stage of cleaning, the first clamping assembly and the second clamping assembly cooperate with each other to make the cystoscope distributed along the X direction, so that the cystoscope can be laid flat. Then, the high-pressure disinfection gas can be introduced into the connecting pipe through the first fluid supply pipe to perform the initial disinfection of its internal channel and clean the debris tissue not attached to the inner wall of the internal channel. After that, the embedded cleaning assembly is used for cleaning. During cleaning, fluid is injected into the internal channel to drive the embedded cleaning assembly to perform mobile cleaning; thereby achieving deep cleaning of the inner wall of the internal channel; then, the embedded cleaning assembly is taken out, and the first clamping assembly and the second clamping assembly are used to cooperate with each other to make the cystoscope 1 distributed along the X direction, and high-pressure disinfection liquid is injected into the internal channel, thereby achieving thorough disinfection and re-cleaning of the internal channel. The cleaning system can effectively clean the inside of a cystoscope. When cleaning the outer wall of a cystoscope, if the outer wall of the cystoscope is cleaned only by flushing, the cleaning effect is poor. When flushing the outer wall of a cystoscope, if the flushing force is large, the scope tube is prone to bending and deformation, making flushing inconvenient. Summary of the invention

After the handle of the cystoscope is inserted into the slot, the cystoscope is located in the flushing unit. A locking unit for fixing the handle of the cystoscope in the slot is provided on the rotating shaft. A plurality of slip rings are slidably sleeved on the flushing unit. The slip rings are concentric with the slots. A plurality of scraping assemblies are slidably provided on the slip rings. The sliding direction of the scraping assemblies on the slip rings is parallel to the radial direction of the slip rings. The scraping assemblies are connected to springs in the slip rings. The springs in the plurality of slip rings on the flushing unit increase their elastic force sequentially from outside to inside in the radial direction of the cylinder.

[0007] Specifically, the upper end of the cylinder is detachably fixedly and sealedly connected with a cover.

[0008] Specifically, the driving unit includes a motor fixed on the bottom plate of the cylinder, a first pulley is coaxially fixed on the output shaft of the motor, a second pulley is coaxially fixed on the rotating shaft below the partition, and the first pulley is connected to the second pulley through a belt drive.

[0009] Specifically, the flushing unit includes a plurality of nozzles fixed on the vertical portion of the frame, the plurality of nozzles on the frame are evenly distributed according to the axial circumference of the slot corresponding to the frame, and a spray hole is processed at one end of the nozzle facing the axis of the slot.

[0010] Specifically, the liquid supply unit includes a liquid pump fixed on the straight part of the frame, a channel is opened in the straight part of the frame, a diversion cavity is opened in the vertical part of the frame, the diversion cavity is connected to the nozzle, the channel is connected to the diversion cavity, and the outlet end of the liquid pump is connected to the channel.

[0011] Specifically, a stopper is fixed to one end of the nozzle facing the rotating shaft, and the nozzle passes through the through hole on the slip ring.

[0012] Specifically, the scraper assembly includes a limit plate located in the slip ring, a sliding rod is fixed to one end of the limit plate facing the center of the slip ring, the axial direction of the sliding rod is parallel to the radial direction of the slip ring, the sliding rod passes through the inner wall of the slip ring, the sliding rod is slidingly connected to the inner wall of the slip ring, a scraper is fixed to one end of the sliding rod facing the center of the slip ring, and a spring is sleeved on the sliding rod between the limit plate and the inner wall of the slip ring.

[0013] Specifically, one end of the scraper facing the center of the slip ring is processed with a guiding inclined surface.

[0014] Specifically, the scraping assemblies on two adjacent slip rings are staggered in the circumferential direction of the slip rings.

[0015] Specifically, the locking unit includes two card plates located in the card slot. The card plates are arc-shaped and symmetrically arranged up and down.

[0019] 3. Since the scraping components on two adjacent slip rings are staggered in the circumferential direction of the slip rings, when all the slip rings on the flushing unit slide toward the vertical part of the frame, the outer wall of the cystoscope is effectively wiped by multiple scrapers, further improving the cleaning effect of the outer wall of the cystoscope.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] like Figure 1-Figure 7 As shown, a cystoscope cleaning system for urology surgery includes a barrel 1, and a cover body is detachably fixedly and sealedly connected to the upper end of the barrel 1. A partition 2 is fixedly and sealedly connected inside the barrel 1, and a rotating shaft 3 is coaxially and rotatably connected with the partition 2. The rotating shaft 3 passes through the partition 2, and a driving unit for driving the rotating shaft 3 to rotate is arranged in the barrel 1 below the partition 2.

[0030] The driving unit includes a motor 4 fixed on the bottom plate of the cylinder 1, a first pulley 5 is coaxially fixed on the output shaft of the motor 4, a second pulley 7 is coaxially fixed on the rotating shaft 3 below the partition 2, and the first pulley 5 is connected to the second pulley 7 through a belt 6.

[0031] A plurality of frames 8 are evenly distributed and fixed on the rotating shaft 3 above the partition 2. The frame 8 is L-shaped as a whole. The straight portion of the frame 8 is fixedly connected to the rotating shaft 3. A flushing unit is fixed on the vertical portion of the frame 8. The flushing unit is connected to the liquid supply unit. A slot 20 concentric with the flushing unit is provided on the rotating shaft 3. The axis of the slot 20 is perpendicular to the axis of the rotating shaft 3. After the handle 23 of the cystoscope is inserted into the slot 20, the cystoscope is located in the flushing unit. A locking unit is provided on the rotating shaft 3 to fix the handle 23 of the cystoscope in the slot 20.

[0032] The flushing unit includes a plurality of nozzles 12, which are fixed on the vertical portion of the frame 8. The plurality of nozzles 12 on the frame 8 are evenly distributed according to the axial circumference of the slot 20 corresponding to the frame 8, and a spray hole is processed at one end of the nozzle 12 facing the axial center of the slot 20.

[0033] The liquid supply unit includes a liquid pump 9 fixed on the straight part of the frame 8, a channel 10 is opened in the straight part of the frame 8, a diversion chamber 11 is opened in the vertical part of the frame 8, the diversion chamber 11 is connected to the nozzle 12, the channel 10 is connected to the diversion chamber 11, and the outlet end of the liquid pump 9 is connected to the channel 10.

[0034] The locking unit includes two card plates 21 located in the card slot 20. The card plates 21 are arc-shaped and symmetrically arranged up and down. The lower card plate 21 is fixed in the card slot 20. A screw rod 22 corresponding to the upper card plate 21 is threadedly connected on the rotating shaft 3. The screw rod 22 is vertically arranged, and the lower end of the screw rod 22 is rotatably connected to the upper card plate 21.

[0035] The flushing unit is provided with a plurality of sliding rings 15 on the sliding sleeve, and the sliding rings 15 are concentric with the slots 20. Specifically, a stopper 13 is fixed to one end of the nozzle 12 facing the rotating shaft 3, and the nozzle 12 passes through the through hole 14 on the sliding ring 15.

[0036] A plurality of scraper assemblies are slidably arranged on the slip ring 15, and the sliding direction of the scraper assemblies on the slip ring 15 is parallel to the radial direction of the slip ring 15. The scraper assemblies are connected to the springs 18 in the slip ring 15, and the springs 18 in the plurality of slip rings 15 on the flushing unit have increasing elastic forces from outside to inside in the radial direction of the cylinder 1.

[0037] The scraper assemblies on two adjacent slip rings 15 are staggered in the circumferential direction of the slip ring 15. The scraper assembly includes a limit plate 17 located inside the slip ring 15, and a slide rod 16 is fixed to one end of the limit plate 17 facing the center of the slip ring 15. The axial direction of the slide rod 16 is parallel to the radial direction of the slip ring 15. The slide rod 16 passes through the inner wall of the slip ring 15, and the slide rod 16 is slidably connected to the inner wall of the slip ring 15. A scraper 19 is fixed to one end of the slide rod 16 facing the center of the slip ring 15. Specifically, a guide slope is processed on one end of the scraper 19 facing the center of the slip ring 15. The spring 18 is sleeved on the slide rod 16 between the limit plate 17 and the inner wall of the slip ring 15.

[0038] When placing the cystoscope, the cystoscope enters the flushing unit through the gap between the nozzles 12, and then the handle 23 of the cystoscope presses the guide slope of the scraper 19 so that the scraper 19, the slide bar 16 and the limit plate 17 move toward the outside of the slip ring 15, and at the same time, the spring 18 in the slip ring 15 is squeezed. When the handle 23 of the cystoscope is located between the two clamping plates 21 in the slot 20, the screw 22 is rotated so that the two clamping plates 21 in the slot 20 clamp the handle 23 of the cystoscope. At this time, the handle 23 of the cystoscope is fixed in the slot 20, and the scraper 19 contacts the outer edge of the handle 23 of the cystoscope.

[0039] The motor 4 is started, and the motor 4 causes the rotating shaft 3, the frame 8, the flushing unit, the plurality of slip rings 15 and the cystoscope to rotate, and the mirror tube 24 of the cystoscope is kept in a horizontal state under the action of the centrifugal force.

[0040] Then start the liquid pump 9, which transports the cleaning liquid in the cylinder 1 above the partition 2 to the nozzle 12 through the channel 10 and the diversion cavity 11. The cleaning liquid entering the nozzle 12 is sprayed out from the spray hole and flushes the outer wall of the cystoscope. After the cleaning liquid sprayed from the spray hole of the nozzle 12 contacts the outer wall of the cystoscope, the cleaning liquid on the outer wall of the cystoscope can move quickly on the outer wall of the cystoscope along the axial direction of the cystoscope under the action of centrifugal force, which can improve the cleaning effect of the cleaning liquid on the outer wall of the cystoscope.

[0041] Since the elastic force of the springs 18 in the multiple slip rings 15 on the flushing unit increases successively from the outside to the inside in the radial direction of the cylinder 1, as the rotation speed of the rotating shaft 3 continues to increase, the centrifugal force also continues to increase, and the slip rings 15 on the flushing unit can slide toward the vertical part of the frame 8 in sequence. During the sliding process of the slip rings 15 toward the vertical part of the frame 8, the scraper 19 can always be in contact with the outer wall of the cystoscope, and the scraper 19 can wipe the outer wall of the cystoscope, thereby improving the cleaning effect of the outer wall of the cystoscope.

[0042] Since the scraping components on two adjacent slip rings 15 are staggered in the circumferential direction of the slip ring 15, when all the slip rings 15 on the flushing unit slide toward the vertical part of the frame 8, the outer wall of the cystoscope is effectively wiped by multiple scrapers 19, further improving the cleaning effect of the outer wall of the cystoscope.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
