Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an instrument cleaning device. Background Art

[0002] Medical devices refer to instruments, equipment, and appliances directly or indirectly used on the human body, with the purpose of diagnosing, preventing, monitoring, treating, or alleviating diseases. Medical devices have various classifications according to their uses. Surgical instruments refer to various tools used by doctors and nurses during surgical procedures for operations such as cutting, separating, hemostasis, suturing, clamping, and fixing to complete surgical treatments.

[0003] During surgical procedures, doctors and nurses also use instruments with lumens, which are intended to enter the body through natural body cavities or surgical incisions to complete functions such as examination, treatment, or tissue handling. However, during surgical procedures, the inner walls of the instrument lumens come into contact with the patient's blood, body fluids, tissue debris, etc., resulting in the adhesion of some tissues and mucus to the inner walls of the instrument lumens.

[0004] In actual clinical work, due to the busy surgical operations, it may not be possible to process surgical instruments in a timely manner. As time goes by, the tissues remaining on the inner walls of the lumens will dry and solidify, adhering more tightly to the inner walls of the lumens, increasing the difficulty of separating the tissues and mucus on the inner walls of the lumens.

[0005] When staff handle instruments with lumens, they need to use a brush to separate the tissues on the inner walls of the lumens. However, the lumens of some instruments have a curved shape, such as endoscope tubes and aspirators. It is difficult for the brush to fully fit the inner walls of the lumens, leaving dead corners, making it impossible to separate the dirt and tissue residues in some areas. Moreover, during the cleaning process, it is easy to scratch the inner walls of the lumens at the curved transition areas. Especially for some instruments with relatively fragile materials, the scratching may damage the smoothness of their surfaces or even cause minor damage, affecting the performance and service life of the instruments. For this reason, we propose an instrument cleaning device. Summary of the Invention

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1 Please refer to Figures 1 to 8 , the present invention provides a technical solution: an instrument cleaning device, including a fixed seat 2, the fixed seat 2 is fixedly connected to the bottom of the instrument basket 1; a placing table 3, the placing table 3 is located on the instrument basket 1, and the placing table 3 is rotatably connected to the instrument basket 1; a placing mechanism 4, there are multiple placing mechanisms 4, and the multiple placing mechanisms 4 are distributed on the outside of the placing table 3 to cooperate with separating the adhesions on the inner and outer surfaces of multiple tubular instruments at the same time, and the placing mechanism 4 vertically clamps the medical instruments with a lumen; a separating mechanism 5, the separating mechanism 5 is located inside the placing mechanism 4, and the separating mechanism 5 simultaneously separates the adhesions on the inner and outer walls of the medical instruments with a lumen, and adjusts the abutting force against the inner and outer tube walls of the instrument according to the change of the instrument diameter; a bending adaptation mechanism 6, the bending adaptation mechanism 6 is located inside the placing mechanism 4, and the bending adaptation mechanism 6 adjusts the bending angle of the separating mechanism 5 according to the moving position of the separating mechanism 5 on the instrument tube wall.

[0024] During use, the staff places the instruments into the instrument basket 1 and transfers them to the cleaning pool for soaking with an enzyme solution. After soaking with the enzyme solution, the faucet of the cleaning pool is docked with the docking pipe 8 in the instrument basket 1. The staff places the instruments with lumens in the instrument basket 1 one by one into the placement mechanism 4. The placement mechanism 4 vertically clamps the medical devices in the lumen, facilitating the separation mechanism 5 to separate the adherents on the inner and outer walls of the lumen when moving in the vertical direction. After clamping multiple instruments with lumens outside the placement table 3, the staff turns on the faucet, and the water flow enters the separation mechanism 5 through the docking pipe 8. When the separation mechanism 5 separates the adherents on the inner and outer walls of the lumen, the flowing water is used to assist the separation mechanism 5 in separating the adherents on the inner wall of the lumen. Since the diameter of some medical devices with lumens gradually decreases, when the separation mechanism 5 moves along the pipe wall, it will adjust the abutting force against the inner and outer pipe walls of the instrument according to the change in the instrument diameter, thereby reducing the influence of the diameter change on the separation effect of the adherents.

[0025] For tubular instruments with a curved shape, when the distance between the outer brush cylinder 50 and the placement table 3 changes, the bending adaptation mechanism 6 synchronously adjusts the bending radian of the inner separation cylinder 51, so that the inner separation cylinder 51 increases the contact area with the inner wall of the lumen when passing through the curved part of the inner wall of the lumen, in order to cooperate with the inner separation cylinder 51 to fully separate the adherents on the inner wall of the curved lumen, avoiding separation dead angles. And by realizing the bending of the inner separation cylinder 51 on the inner wall of the lumen, the impact force of the inner separation cylinder 51 on the inner wall of the lumen when passing through the curved part of the lumen is reduced, minimizing the damage to the inner wall of the curved transition part of the lumen.

[0026] The placement mechanism 4 includes a fixing plate 40 fixedly connected to the side of the placement table 3. A movable plate 41 is provided below the fixing plate 40. An adjustment groove 42 is formed in the inner wall of the placement table 3. The movable plate 41 is slidably connected to the inner wall of the adjustment groove 42. A plurality of rubber bumps 43 are fixedly connected to one end of the movable plate 41 close to the adjustment groove 42. The rubber bumps 43 are clamped with the inner wall of the adjustment groove 42. Airbag clamps 44 are fixedly connected to the inner sides of the fixing plate 40 and the movable plate 41 respectively. The airbag clamps 44 are in a C shape.

[0027] When the staff places the instrument with a lumen, the two ends of the lumen instrument are respectively inserted through the openings of the airbag clamps 44. The extrusion of the instrument on the airbag clamps 44 causes the airbag clamps 44 to deform. When the airbag clamps 44 deform, the air pressure inside the airbag clamps 44 also increases. Thus, the increased air pressure will push the airbag clamps 44 to abut against the outside of the instrument, thereby realizing the clamping of the instrument and keeping the instrument in a vertically placed state.

[0028] When placing a tubular instrument with a curved shape (such as a suction tube), first adjust the instrument to a posture where the tube body gradually approaches the placement table 3 from top to bottom. Then, adjust the position of the movable plate 41. When the rubber bump 43 is deformed by extrusion as the movable plate 41 slides on the inner wall of the adjustment groove 42, and when the movable plate 41 moves to a new position, the rubber bump 43 returns to its original position by its own elasticity, thereby limiting the position of the movable plate 41 again, causing the airbag clip 44 inside the movable plate 41 to be misaligned with the airbag clip 44 inside the fixed plate 40, so as to cooperate with clamping both ends of the tubular instrument with a curved shape and keep the instrument in a posture where the tube body gradually approaches the placement table 3 from top to bottom.

[0029] The separation mechanism 5 includes an outer brush tube 50 and an inner separation tube 51. An airbag column one 52 is fixedly connected to the outside of the outer brush tube 50. A moving seat 53 is located outside the airbag column one 52. A rotating member 54 for driving the airbag column one 52 to rotate on the inner wall of the moving seat 53 is provided on the inner wall of the moving seat 53. A telescopic plate 55 is fixedly connected to the outside of the moving seat 53. A lifting plate 56 is located outside the telescopic plate 55. The lifting plate 56 is slidably connected to the inner wall of the placement table 3. One end of the telescopic plate 55 close to the lifting plate 56 is located inside the lifting plate 56 and is slidably connected to the inner wall of the lifting plate 56. A tension spring 57 is fixedly connected to one end of the telescopic plate 55 close to the lifting plate 56. The tension spring 57 is fixed to the inner wall of the lifting plate 56. A multi-stage electric telescopic rod 58 is installed outside the placement table 3. The telescopic end of the multi-stage electric telescopic rod 58 is fixed to the lifting plate 56. An airbag column two 59 is fixedly connected to the outside of the inner separation tube 51. A synchronizing member 510 for adjusting the size of the airbag column two 59 according to the shape change of the airbag column one 52 is provided between the airbag column two 59 and the airbag column one 52. A plurality of rubber tubes 511 are fixedly connected to the inner wall of the airbag column two 59. The rubber tubes 511 communicate with the inner wall of the inner separation tube 51. The rubber tubes 511 conduct the water flow on the inner wall of the inner separation tube 51 into the inner wall of the instrument lumen. When the airbag column two 59 expands, the rubber tubes 511 made of rubber can also be stretched. A flexible cleaning pad 512 is wrapped outside the airbag column two 59. The flexible cleaning pad 512 is made of microfiber with a friction coefficient lower than 0.1 to reduce damage to the inner wall of the lumen. A connecting member 513 is provided between the top of the inner separation tube 51 and the moving seat 53.

[0030] When separating the adhesives on the surface of the instrument, the inner separation tube 51 is placed into the inner wall of the lumen through the connecting member 513, and the outer brush tube 50 is placed outside the tube wall of the instrument. The outer wall of the instrument is inserted into the inside of the outer brush tube 50 by squeezing the airbag column one 52.

[0031] When separating the adherents on the inner wall of the instrument lumen and the outer surface of the instrument, the multi-stage electric telescopic rod 58 drives the lifting plate 56 to move up and down in the vertical direction. The lifting plate 56 drives the telescopic plate 55 to move in the vertical direction, so that the telescopic plate 55 drives the moving seat 53 to move in the vertical direction, causing the outer brush cylinder 50 to move along the outer surface of the instrument. And the rotating member 54 drives the first airbag column 52 to rotate reciprocally inside the moving seat 53. The first airbag column 52 drives the outer brush cylinder 50 to rotate reciprocally on the outer surface of the instrument to cooperate in separating the adherents on the outer surface of the instrument. When the moving seat 53 moves in the vertical direction, it drives the inner separation cylinder 51 to move on the inner wall of the lumen through the connecting member 513. The inner separation cylinder 51 drives the flexible cleaning pad 512 to slide on the inner wall of the lumen. And water flows into the inner wall of the instrument lumen through the rubber tube 511. The flexible cleaning pad 512 cooperates with the flowing water to separate the adherents soaked in the enzyme solution on the inner wall of the instrument lumen.

[0032] When the outer brush cylinder 50 moves along the outer surface of the instrument, if the diameter of the instrument gradually decreases from top to bottom, the synchronizing member 510 inflates the first airbag column 52 and simultaneously evacuates the second airbag column 59. So that after the first airbag column 52 expands, it drives the outer brush cylinder 50 to approach the instrument tube wall with a reduced size. After the gas in the second airbag column 59 is evacuated, the second airbag column 59 contracts, thereby reducing the extrusion force of the flexible cleaning pad 512 on the reduced inner wall of the lumen. When the inner separation cylinder 51 slides on the inner wall of the lumen, the scraping force of the flexible cleaning pad 512 on the inner wall of the lumen is reduced.

[0033] When the outer brush cylinder 50 moves in the vertical direction on the outer surface of the instrument, if the instrument body has a curved shape, since the instrument is in a posture where the body gradually approaches the placement table 3 from top to bottom during installation. When the outer brush cylinder 50 moves along the body, under the elastic force of the tension spring 57, the telescopic plate 55 slides inside the lifting plate 56. The telescopic plate 55 drives the moving seat 53 to approach the placement table 3. The moving seat 53 drives the outer brush cylinder 50 to approach the placement table 3. And when the moving seat 53 moves, it triggers the bending adaptation mechanism 6. The bending adaptation mechanism 6 controls the bending of the inner separation cylinder 51 on the inner wall of the lumen. So that when the inner separation cylinder 51 passes through the bent part of the inner wall of the lumen, the contact area with the inner wall of the lumen is increased, enabling the inner separation cylinder 51 to fully separate the adherents on the inner wall of the bent lumen, avoiding separation dead corners. And by realizing the bending of the inner separation cylinder 51 on the inner wall of the lumen, the impact force of the inner separation cylinder 51 on the inner wall of the bent part of the lumen when sliding on the inner wall of the lumen is reduced, and the scraping force on the inner wall of the bent transition part of the lumen is alleviated.

[0034] The rotating member 54 includes a toothed ring 514 fixedly connected to the outer side of the first airbag column 52. A toothed plate 515 is meshed with the outer side of the toothed ring 514. The toothed plate 515 is slidably connected to the inner wall of the moving seat 53. A transmission block 516 is fixedly connected to the outer side of the moving seat 53. A bidirectional lead screw 517 is rotatably connected to the inner wall of the moving seat 53. The bidirectional lead screw 517 is threadedly connected to the inner wall of the transmission block 516. The output end of the micro motor 518 is fixed to the bidirectional lead screw 517, and the micro motor 518 is installed on the inner wall of the moving seat 53.

[0035] When separating the adhesives on the outer side of the instrument, the micro motor 518 drives the bidirectional lead screw 517 to rotate. Since the transmission block 516 is threadedly connected to the bidirectional lead screw 517, when the bidirectional lead screw 517 rotates, it drives the transmission block 516 to reciprocate on the surface of the bidirectional lead screw 517. The reciprocating movement of the transmission block 516 drives the toothed plate 515 to reciprocate on the inner wall of the moving seat 53. When the transmission block 516 moves from one end of the stroke of the bidirectional lead screw 517 to the other end, the toothed plate 515 only drives the toothed ring 514 to rotate by 20°. When the transmission block 516 reciprocates on the surface of the bidirectional lead screw 517, the toothed plate 515 drives the toothed ring 514 to alternately switch between clockwise rotation of 20° and counterclockwise rotation of 20°. Furthermore, the first airbag column 52 drives the outer brush barrel 50 to alternately switch between two rotation modes of clockwise rotation of 20° and counterclockwise rotation of 20° to cooperate with separating the adhesives on the outer side of the instrument.

[0036] The synchronizing member 510 includes a processing box 519 fixedly installed on the surface of the moving seat 53. A piston plate 520 is slidably connected to the inner wall of the processing box 519. A return spring 521 is fixedly connected to the surface of the piston plate 520, and the return spring 521 is installed on the inner wall of the processing box 519. A first connecting pipe 522 communicates with the bottom end of the processing box 519, and the first connecting pipe 522 communicates with the first airbag column 52. A second connecting pipe 523 communicates with the top of the processing box 519. One end of the second connecting pipe 523 away from the processing box 519 communicates with the second airbag column 59. A temporary storage airbag 524 communicates with the bottom of the second airbag column 59, and the temporary storage airbag 524 is in a flat state in the initial state.

[0037] When the diameter of the instrument increases, the tube wall of the instrument squeezes the first airbag column 52. After the first airbag column 52 is squeezed, the internal gas enters the processing box 519 through the first connecting pipe 522, increasing the air pressure in the processing box 519. The increased air pressure pushes the piston plate 520 to slide upward along the inner wall of the processing box 519. The piston plate 520 compresses the return spring 521. Thus, the piston plate 520 injects the gas in the processing box 519 into the inner wall of the second airbag column 59 through the second connecting pipe 523, causing the second airbag column 59 to expand. Since the size of the first airbag column 52 is larger than that of the second airbag column 59, when the size of the first airbag column 52 decreases, the gas injected into the second airbag column 59 will cause a greater expansion amplitude of the second airbag column 59. To avoid excessive extrusion force between the flexible cleaning pad 512 and the inner wall of the lumen due to the large expansion amplitude of the second airbag column 59, a temporarily stored airbag 524 in a flat initial state is connected above the second airbag column 59 in this application. Thus, after the air pressure in the second airbag column 59 increases, the gas will be injected into the flat temporarily stored airbag 524, causing the temporarily stored airbag 524 to also expand. Thus, when the outer brush barrel 50 slides along the surface of the instrument, if the diameter of the instrument increases, the flexible cleaning pad 512 on the inner wall of the lumen will also expand outward to approach the inner wall of the lumen to cooperate with improving the separation effect of the adhesions on the inner wall of the lumen.

[0038] When the diameter of the instrument decreases, the return spring 521 in a stretched state pushes the piston plate 520 to slide downward, thereby injecting the gas in the processing box 519 into the first airbag column 52. Thus, the first airbag column 52 expands, causing the outer brush barrel 50 to approach the outside of the instrument. At the same time, when the piston plate 520 slides downward, it will extract the gas in the second airbag column 59 and the temporarily stored airbag 524, thereby reducing the size of the second airbag column 59 and avoiding excessive friction between the flexible cleaning pad 512 and the inner wall of the lumen when the inner separation cylinder 51 slides on the inner wall of the lumen, resulting in damage to the inner wall of the lumen.

[0039] The connecting member 513 includes a support cylinder 525 fixedly connected to the top of the processing box 519. The top of the support cylinder 525 is fixedly connected to a connection box 526. The support cylinder 525 and the connection box 526 are located outside the second connecting pipe 523. The bottom of the connection box 526 is communicated with a silica gel tube 527. The minimum bending radius of the silica gel tube 527 is 10 cm, matching the curvature of common tubular instruments. One end of the silica gel tube 527 away from the connection box 526 is communicated with the inner separation cylinder 51.

[0040] When the staff places the instrument, since the silica gel tube 527 is made of silica gel, after the staff places the tubular instrument inside the airbag clip 44, the staff can bend the silica gel tube 527 to place the inner separation cylinder 51 on the inner wall of the instrument lumen.

[0041] When the moving seat 53 moves in the vertical direction, the moving seat 53 drives the connecting box 526 to move in the vertical direction through the support cylinder 525. The connecting box 526 drives the inner separation cylinder 51 to move in the vertical direction through the silica gel tube 527. And the silica gel tube 527 is made of silica gel material and has good bending flexibility, so that when it cooperates with and follows the movement of the moving seat 53 in the vertical direction, it can also bend.

[0042] A water storage box 7 is fixedly connected to the top of the placing table 3. A docking pipe 8 communicates with the top of the water storage box 7. The docking pipe 8 is connected to the faucet of the cleaning pool. A plurality of water delivery pipes 9 communicate with the outside of the water storage box 7. The plurality of water delivery pipes 9 communicate with the corresponding connecting boxes 526 respectively. The water delivery pipes 9 are arranged obliquely.

[0043] When the faucet is opened, water flows into the water storage box 7 through the docking pipe 8. And the liquid in the water storage box 7 enters the corresponding connecting box 526 through the water delivery pipe 9. The liquid in the connecting box 526 is injected into the inner separation cylinder 51 through the silica gel tube 527 and is injected into the inner wall of the pipe cavity through the rubber tube 511. When the flexible cleaning pad 512 separates the adherents on the inner wall of the pipe cavity, the flowing water stream assists the flexible cleaning pad 512 to clean the adherents on the inner wall of the pipe cavity, improving the separation effect.

[0044] The bending adaptation mechanism 6 includes a connecting plate 60 installed on the outer side of one end of the silica gel tube 527 close to the inner separation cylinder 51. A bending spring 61 is installed between the connecting plate 60 and the top of the inner separation cylinder 51. An adjusting member 62 for adjusting the bending radian of the bending spring 61 according to the moving position of the outer brush cylinder 50 is arranged outside the placing table 3.

[0045] When the outer brush cylinder 50 passes through the bending transition part of the instrument, the moving seat 53 moves towards the placing table 3 under the pulling force of the tension spring 57. The movement of the moving seat 53 triggers the adjusting member 62. The adjusting member 62 drives the inner separation cylinder 51 to rotate relative to the silica gel tube 527, that is, the inner separation cylinder 51 approaches the placing table 3. The inner separation cylinder 51 drives the bending spring 61 to bend, so that when the inner separation cylinder 51 passes through the bending part of the inner wall of the pipe cavity, the contact area with the inner wall of the pipe cavity is increased, so as to cooperate with the inner flexible cleaning pad 512 to fully separate the adherents on the inner wall of the pipe cavity at the bending part, avoiding the occurrence of separation dead angles. And by realizing the bending of the inner separation cylinder 51 on the inner wall of the pipe cavity, the impact force of the inner separation cylinder 51 passing through the bending part of the instrument on the inner wall of the pipe cavity is reduced, and the scraping force on the inner wall of the bending transition part of the pipe cavity is reduced.

[0046] The adjusting member 62 includes an electromagnet 63 mounted on the surface of the placing table 3. There are multiple electromagnets 63 which are vertically distributed. A trigger block 64 is provided outside each electromagnet 63. A trigger rod 65 is fixedly connected to the outside of the trigger block 64. A sliding groove 66 is formed in the inner wall of the placing table 3. The trigger rod 65 is slidably connected to the inner wall of the sliding groove 66. A sliding rheostat 67 is mounted on the inner wall of the sliding groove 66. The sliding rheostat 67 and the electromagnet 63 are connected in series in a circuit. The sliding key of the sliding rheostat 67 is connected to the trigger rod 65. A compression spring 611 is fixedly connected to the outside of the trigger rod 65. When the pressing rod 69 does not press the trigger rod 65, the compression spring 611 in the compressed state pushes the trigger rod 65 to reset, and the trigger rod 65 drives the sliding key of the sliding rheostat 67 to reset. A normally open push-button switch 68 is mounted on the inner wall of the sliding groove 66. The normally open push-button switch 68 is used to control the closing and opening of the circuit where the sliding rheostat 67 and the electromagnet 63 are located. A pressing rod 69 is fixedly connected to one side of the moving seat 53 close to the trigger block 64. An iron sheet 610 is fixedly connected to the inner wall of the inner separation cylinder 51.

[0047] The normally open push-button switch 68 is a mature existing technology in the market. It usually consists of a button cap, a spring, a bridge-type moving contact, a static contact and a housing, etc. Its principle is: when not pressed in the normal state, the moving contact and the static contact are separated, and the circuit is in an open state; when the button cap is pressed, the moving contact moves downward under the action of pressure and contacts the static contact, making the circuit closed; when the button cap is released, the spring will make the moving contact return to the initial position and separate from the static contact, and the circuit returns to the open state again.

[0048] The materials of the instruments with lumens in medical devices are diverse. Most are made of titanium and titanium alloys and polymer materials. Titanium and titanium alloys belong to non-magnetic materials and will not produce a shielding effect on the magnetic field of the electromagnet 63. They are widely used in some medical devices with high requirements for the magnetic field environment, such as interventional instruments under magnetic resonance imaging guidance; polymer materials also will not produce a shielding effect on the magnetic field. Thus, the magnetic field generated by the electromagnet 63 can attract the iron sheet 610 to adjust the bending amplitude of the inner separation cylinder 51 on the inner wall of the lumen.

[0049] When the outer brush cylinder 50 slides at the bending part of the instrument tube body, the outer brush cylinder 50 approaches the placing table 3. When the tension spring 57 drives the telescopic plate 55 to move towards the placing table 3, the telescopic plate 55 drives the moving seat 53 to move, and the moving seat 53 drives the pressing rod 69 to approach the placing table 3. The pressing rod 69 contacts and presses the trigger block 64. The trigger block 64 drives the trigger rod 65 to slide on the inner wall of the sliding groove 66. When the trigger rod 65 slides on the inner wall of the sliding groove 66, it presses the normally open push-button switch 68, making the circuit where the electromagnet 63 is located closed. After the electromagnet 63 is powered on, it generates a magnetic field, thus attracting the iron sheet 610 on the inner wall of the inner separation cylinder 51, making the iron sheet 610 drive the inner separation cylinder 51 to approach the electromagnet 63, thereby making the bending spring 61 bend.

[0050] The trigger rod 65 contacts the sliding key of the sliding rheostat 67. As the moving seat 53 gets closer to the placement table 3, the farther the trigger rod 65 slides along the inner wall of the sliding slot 66, the greater the distance the sliding key of the sliding rheostat 67 is driven by the trigger rod 65. The connection mode between the trigger rod 65 and the sliding rheostat 67 is that the closer the trigger rod 65 drives the sliding key to the placement table 3, the smaller the resistance value of the sliding rheostat 67. As a result, the current in the circuit where the electromagnet 63 is located is greater, and the magnetic field generated by the electromagnet 63 is stronger. Specifically, for every 1 mm the trigger rod 65 moves, the resistance value of the sliding rheostat 67 decreases by 0.5 Ω, thereby linearly increasing the suction force of the electromagnet 63, making the moving amplitude of one end of the iron sheet 610 installed in the inner separation cylinder 51 located in the instrument lumen larger. Thus, when the inner separation cylinder 51 passes through the bent part of the lumen inner wall, the contact area with the lumen inner wall increases, so as to cooperate with the flexible cleaning pad 512 to fully separate the adhesions on the inner wall of the bent lumen, avoiding separation dead angles, and by realizing the bending of the inner separation cylinder 51 on the lumen inner wall, the impact force of the inner separation cylinder 51 on the lumen inner wall is reduced, and the scraping force on the inner wall at the bent transition of the lumen is alleviated.

[0051] Embodiment 2 In this Embodiment 2, other structures remain unchanged. Different from Embodiment 1, a support plate 20 is fixedly connected to the outside of the fixed seat 2, and a brush plate 21 is fixedly connected to the end of the support plate 20. The brush plate 21 is located below the movable plate 41. When the staff rotates the placement table 3, the bottom end of the instrument with a lumen can pass through the brush plate 21, so that the brush plate 21 cleans the port of the instrument, improving the separation effect of the instrument adhesions.
