Description

Technical Field

[0001] This invention relates to the field of instrument cleaning technology, specifically to an adjustable surgical instrument cleaning device. Background Technology

[0002] The Central Sterile Supply Department (CSSD) is responsible for the cleaning, disinfection, packaging, sterilization, and distribution of all reusable medical instruments, equipment, and supplies within the hospital. Its work quality directly reflects the overall quality of sterile supplies in the hospital and is crucial for medical safety. It is a vital department for infection prevention and control. With the continuous updating and development of medical devices, laparoscopy has become widely used in clinical practice due to its minimal surgical trauma and rapid postoperative recovery. However, laparoscopic instruments are highly precise, with narrow and long lumens, making them prone to adhering to blood, body fluids, and secretions after use. This makes them difficult to clean completely, resulting in low-quality cleaning, lumen blockage, and affecting sterilization and usability. To improve the cleaning qualification rate of laparoscopic instruments and facilitate their use, special cleaning brushes are needed to clean the inner walls of the lumens.

[0003] Existing methods involve using specialized cleaning brushes to thoroughly clean suction and biopsy tubing. Water is injected using a syringe for rinsing, followed by repeated scrubbing with a soft brush until the brush head is visible at both ends to completely remove tissue debris. The brush head must be rinsed under running water before being withdrawn for further cleaning. Subsequently, a high-pressure water gun flushes out debris from the inner wall of the tubing. The brush end, which passes through the tubing, is rinsed with running water and then withdrawn. During rinsing, some dirt is dislodged by the running water, but some is pushed towards the base of the brush. Because the bristles are denser at the base, stubborn dirt may not be easily removed by the running water. When the brush is withdrawn, the bristles are bent by the tubing wall, causing any loose dirt to re-enter the tubing. To address this, we propose an adjustable surgical instrument cleaning device. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable surgical instrument cleaning device to solve the problems mentioned in the background art.

[0009] Preferably, the other end of the wire rope is fixed to the connecting plate, a sliding cylinder is fixed on the surface of the connecting plate, and the sliding cylinder is sleeved on the outside of the end face of the hose. The top of the connecting plate is movably connected to the connecting rod 1 through the movable shaft 1, and the end of the connecting rod 1 away from the connecting plate is movably connected to the connecting rod 2 through the movable shaft 2. The side of the connecting rod 2 away from the connecting rod 1 is fixedly connected to the output shaft of the motor.

[0010] Preferably, a fixing ring is fixed to the outer wall of the slide, and a sliding plate is fixed to the side of the fixing ring. The sliding plate is slidably connected to the fixing frame through a slider, and the inside of the fixing frame is provided with a sliding opening that cooperates with the slider.

[0011] Preferably, the end face of the motor is fixed to the surface of the fixing frame, the bottom of the fixing frame is fixed to the surface of the stacking plate, the end face of the stacking plate is fixed to the surface of the hose, the bottom of the two sets of stacking plates is fixed with insert blocks, the insert blocks are inserted into the insertion port two opened inside the connecting seat two, and the inner wall of the connecting seat two is fixed with a rubber limiting ring that abuts against the operating port inlet seat.

[0016] The brush bristles clean the stains on the inner wall of the endoscope tube. The high-frequency pulsed water from the outlet rinses the stains, preventing them from sticking to the inner wall of the endoscope tube. By pulling the steel wire rope, the pressure plate moves, which pushes the brush bristles open and causes them to shake. This opens the base of the brush bristles, allowing the high-frequency pulsed water to flow into the opened space, which helps the stains at the base of the brush bristles to fall off. This prevents the stains from being unable to be washed off by the flowing water, thus preventing the cleaning tube bristles from being squeezed and bent by the cavity wall when the cleaning tube is pulled back, causing the stains to fall off and re-enter the endoscope tube.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-13 The present invention provides a technical solution:

[0033] Example 1,

[0034] An adjustable surgical instrument cleaning device includes: a scope tube 1, with an operating port 21 on the side of its end; a cleaning mechanism 3, comprising a flexible tube 31 passing through the interior of the scope tube 1, a cleaning tube 32 connected to one end of the flexible tube 31, a steel wire rope 35 inserted inside the cleaning tube 32, a water outlet 34 on the outer wall of the cleaning tube 32 containing a bristle tuft 33, and cleaning water entering the cleaning tube 32 being sprayed out through the water outlet 34; a pressure plate 36 fixed to the outer wall of the steel wire rope 35 to push the bristle tuft 33, the pressure plate 36 reciprocating to push the bristle tuft 33 to shake, thereby facilitating the removal of dirt from the surface of the bristle tuft 33 roots; the steel wire rope 35 providing support for the flexible tube 31 to prevent excessive bending of the flexible tube 31; water flowing from the flexible tube 31 into the cleaning tube 32; and the cleaning tube 32 containing... Water is flushed out through the outlet 34 to assist the brush tuft 33 in cleaning the inner wall of the lens tube 1. The high-frequency pulsed water from the outlet 34 washes away the stains on the inner wall of the lens tube 1, preventing the stains from sticking to the inner wall of the lens tube 1. The pressure plate 36 is moved by pulling the steel wire rope 35. The pressure plate 36 moves and presses against the brush tuft 33, which can open the brush tuft 33 and make it shake. This causes the base of the brush tuft 33 to be opened. At this time, the high-frequency pulsed water flows into the opened space to flush the water, which helps the stains at the base of the brush tuft 33 to fall off. At the same time, when the brush tuft 33 is cleaning and rubbing against the inner wall, the water flow washes the brush tuft 33, which can cool the brush tuft 33 and reduce the heat generated by the friction between the brush tuft 33 and the inner wall of the lens tube 1, thus affecting the service life of the brush tuft 33.

[0035] The outlet 34 is designed with slanted openings on both sides near the end of the wire rope 35. The slanted openings guide the water flow, allowing the water to be sprayed out through the outlet 34. The slanted guidance also makes the water flow more concentrated and increases the water pressure.

[0036] The top and bottom of the outer wall of the pressure plate 36 are fixed with a support plate 37, and the side of the support plate 37 away from the pressure plate 36 is set as a pointed tip. Through the design of the support plate 37, when the pressure plate 36 moves to contact the bristle tuft 33, the pointed tip design makes it easier for the support plate 37 to open the middle of the bristle tuft 33, which is conducive to the pressure plate 36 moving to the middle of the bristle tuft 33, thus pushing the bristle tuft 33 and making the base of the bristle tuft 33 shake, thereby facilitating the removal of stains.

[0037] One end of the wire rope 35 is fixed with a connector 38, and the surface of the connector 38 is glued with a plug ring 41 inserted into the connector seat 39. The end face of the connector seat 39 is fixed to the surface of the cleaning tube 32. The connector seat 39 has an opening that mates with the plug ring 41. The connector 38 is hemispherical, and the end of the connector 38 away from the cleaning tube 32 is arc-shaped. The design of the connector 38 facilitates the movement of the connector 38 inside the mirror tube 1, reduces the resistance to the movement of the connector 38, and prevents dirt from sticking to the forward surface of the connector 38. The engagement of the plug ring 41 with the connector seat 39 makes the sealing effect of the connector 38 and the cleaning tube 32 better.

[0038] The other end of the wire rope 35 is fixed to the connecting plate 51. A slide cylinder 52 is fixed to the surface of the connecting plate 51, and the slide cylinder 52 is sleeved on the outside of the end face of the hose 31. The top of the connecting plate 51 is movably connected to the connecting rod 53 via a movable shaft. The end of the connecting rod 53 away from the connecting plate 51 is movably connected to the connecting rod 54 via a movable shaft. The side of the connecting rod 54 away from the connecting rod 53 is fixedly connected to the output shaft of the motor 55. When the motor 55 works, it drives the connecting rod 54 to rotate through the output shaft. The second connecting rod 54 rotates around the output shaft of the motor 55. The second connecting rod 54 drives the first connecting rod 53 to rotate. The rotation of the first connecting rod 53 pushes the connecting plate 51 to move. The connecting plate 51 drives the wire rope 35 to move synchronously, realizing the pulling operation of the wire rope 35. The slide cylinder 52 is sleeved on the outer wall of the hose 31 and moves. The wire rope 35 is pulled and moved by the motor 55, the second connecting rod 54, the first connecting rod 53 and the connecting plate 51, without the need for manual pulling, making the operation more convenient.

[0039] A fixing ring 57 is fixed to the outer wall of the slide cylinder 52, and a sliding plate 58 is fixed to the side of the fixing ring 57. The sliding plate 58 is slidably connected to the fixing frame 56 through the slider 59. The fixing frame 56 has a sliding opening inside that cooperates with the slider 59. The movement of the slide cylinder 52 is limited by the fixing ring 57 and the sliding plate 58, so that the slide cylinder 52 can move stably on the surface of the hose 31, and the stability effect is better.

[0040] The end face of the motor 55 is fixed to the surface of the fixing bracket 56, the bottom of the fixing bracket 56 is fixed to the surface of the laying plate 61, the end face of the laying plate 61 is fixed to the surface of the hose 31, and the bottom of the two sets of laying plates 61 are fixed with inserts 62. The inserts 62 are inserted into the second insertion slot opened inside the second connector 63. The inner wall of the second connector 63 is fixed with a rubber limiting ring 64 that abuts against the inlet seat of the operating port 21. Through the laying plates 61 and the inserts 62, the tail of the hose 31 can be supported and laid on the surface of the inlet seat of the operating port 21. The hose 31 is supported and limited so that its tail is centered on the inlet seat of the operating port 21, preventing the tail of the hose 31 from rubbing against the inner wall of the inlet seat and causing wear. At the same time, the hose 31 is limited so that it is placed more stably. The rubber limiting ring 64 elastically deforms and presses against the outer wall of the inlet seat, so as to achieve stable docking between the connecting seat 2 63 and the inlet seat, making the motor 55 work more stably and facilitating the movement of the motor 55, connecting rod 2 54, connecting rod 1 53 and connecting plate 51.

[0041] The outer wall of the hose 31 is connected to the pressure measuring tube 66 via the connecting tube 65. The surface of the pressure measuring tube 66 is equipped with a pressure gauge 67 to monitor the water pressure. The pressure gauge 67 monitors the water pressure input to the pressure measuring tube 66. When part of the outlet 34 is blocked by dirt, or the hose 31 is bent, the water pressure inside the hose 31 increases. At this time, the value of the pressure gauge 67 changes, and the pressure gauge 67 transmits the signal to the signal receiving end of the controller. After receiving the signal, the controller determines that the outlet 34 is blocked by dirt or the hose 31 is bent. Next, the controller controls the motor 55 to start working. The operation of the motor 55 indirectly realizes the pulling operation of the wire rope 35 to clear the outlet 34. When the wire rope 35 is pulled, it can also straighten the bent hose 31. The water pressure is monitored by the pressure gauge 67 to control the wire rope 35 to clean. No manual monitoring is required. When the cleaning tube 32 is inside the mirror tube 1, it is not easy for personnel to observe the water pressure. Therefore, the monitoring design of the pressure gauge 67 is more convenient.

[0042] The end face of the pressure measuring tube 66 is connected to the water pump 69 through the water pipe 68, and the water pump 69 is placed at the bottom of the water tank 75. The water pump 69 is rechargeable and can be equipped with a battery to ensure continuous operation. The water flow inside the water tank 75 is delivered to the inside of the water pipe 68 through the water pump 69, providing a high-frequency pulse water flow to the inside of the hose 31. The surface of the pressure measuring tube 66 is equipped with a speed adjustment button, which is divided into low, medium and high speeds. The low speed is suitable for precision instruments, the high speed is suitable for heavily soiled endoscope tube 1, and the medium speed is suitable for cleaning ordinary instruments with moderate needs. The adjustment button controls the working intensity of the water pump 69, so that the working intensity of the water pump 69 can be adjusted according to the degree of dirt and material of the cleaning instrument, resulting in better adjustment effect and a wider range of applications.

[0043] According to the above embodiments, Embodiment Two

[0044] A connecting ring 42 is fixed to the inner wall of the hose 31 near the cleaning tube 32, and a ball 45 that is locked inside the guide port 44 is fixed to the outer wall of the connecting ring 42. A notch 43 that mates with the connecting ring 42 is provided on the side of the cleaning tube 32 near the hose 31. The guide port 44 is located inside the notch 43 and is spiral-shaped. The end face of the hose 31 is connected to the outer ring of the end face of the cleaning tube 32 via an elastic element 46. The elastic element 46 enables the hose 31 and the cleaning tube 32 to be connected simultaneously. It possesses high elasticity, such as a soft rubber sheet. When the cleaning tube 32 is inserted into the endoscope tube 1, it pushes the flexible tube 31 forward a certain distance. The cleaning tube 32 is squeezed by the inner wall of the endoscope tube 1, generating a backward force. At this time, the cleaning tube 32 squeezes the elastic element 46, and the elastic element 46 is compressed. Simultaneously, when the cleaning tube 32 is squeezed, it moves towards the flexible tube 31, increasing the portion of the connecting ring 42 that extends into the recess 43. The sliding ball 45 slides inside the guide port 44. With a spiral design, the slider 45 slides spirally inside the guide port 44, which drives the cleaning tube 32 to rotate synchronously, realizing the rotational insertion of the cleaning tube 32. After the hose 31 has advanced a certain distance, the operator holds the hose 31 close to the inlet seat of the operating port 21. The operator needs to change the holding position. During the time when the hose 31 stops moving, the restoring force of the elastic element 46 pushes the cleaning tube 32 away from the hose 31. At the same time, when the water flow inside the hose 31 rushes into the cleaning tube 32, it also has a force that pushes the cleaning tube 32 away from the hose 31, assisting the elastic element 46 to return to its original state. At this time, the elastic element 46 pulls the cleaning tube 32 to move. With the cooperation of the slider 45 and the guide port 44, the cleaning tube 32 rotates in the opposite direction to return to its original position, realizing the forward and reverse rotation of the cleaning tube 32 when it is inserted into the endoscope tube 1. The rotational insertion has less friction. Compared with the direct insertion of the cleaning tube 32 into the endoscope tube 1, the rotational insertion of the cleaning tube 32 is more conducive to the movement of the cleaning tube 32.

[0045] According to the above embodiments, in Embodiment 3,

[0046] Multiple sets of cleaning tubes 32 of different sizes are stored inside the drying box 71, and a disinfection lamp 72 is provided on the side of the inner wall of the drying box 71. The side of the outer wall of the drying box 71 is connected to the lid 73 by a hinge. The middle of the inside of the drying box 71 is glued with a sponge seat 74 that limits the cleaning tubes 32, which can accommodate the storage and placement of brushes of various sizes. Each drying box 71 contains cleaning tubes 32 of different diameters, which can accommodate instruments of different diameters to be cleaned, thus making the range of applications wider.
