Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to an instrument cleaning device. Background Art

[0002] Medical devices refer to instruments, equipment, and appliances that are used directly or indirectly on the human body for the diagnosis, prevention, monitoring, treatment, or relief of diseases. Medical devices are classified into various categories based on their uses. Surgical instruments refer to various tools used by doctors and nurses during surgery to perform cutting, separation, hemostasis, suturing, clamping, fixation, and other operations to complete surgical treatment.

[0003] During surgery, doctors and nurses also use instruments with lumens. Their purpose is to enter the body through natural cavities or surgical incisions to perform functions such as examination, treatment, or tissue processing. However, during the operation, the inner wall of the instrument lumen will come into contact with the patient's blood, body fluids, tissue debris, etc., causing some tissue and mucus to adhere to the inner wall of the instrument lumen.

[0004] However, in actual clinical work, due to the busy operation, surgical instruments may not be processed in time. As time goes by, the tissue remaining on the inner wall of the lumen will dry and solidify, and adhere more tightly to the inner wall of the lumen, increasing the difficulty of separating the inner wall tissue and mucus.

[0005] As a result, when staff handle instruments with lumens, they need to use a brush to separate the tissue on the inner wall of the lumen. However, the lumen of some instruments has a curved shape, such as endoscope tubes and suction devices. It is difficult for the brush to completely fit the inner wall of the lumen, leaving dead corners, making it impossible to separate dirt and tissue residues in some areas. In addition, the inner wall of the lumen at the bend transition is easily scratched during the cleaning process. Especially for some instruments with relatively fragile materials, scratches may destroy the smoothness of their surface and 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

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figures 1 to 8 The present invention provides a technical solution: an instrument cleaning device, comprising a fixing seat 2, which is fixedly connected to the bottom of an instrument basket 1; a placing table 3, which is located on the instrument basket 1 and is rotatably connected to the instrument basket 1; a placing mechanism 4, which is provided with multiple placing mechanisms 4, and multiple placing mechanisms 4 are distributed on the outside of the placing table 3 to cooperate with the simultaneous separation of adhesions on the inner and outer surfaces of multiple tubular instruments, and the placing mechanism 4 vertically clamps the medical instrument with a lumen; a separating mechanism 5, which is located on the inside of the placing mechanism 4, and the separating mechanism 5 simultaneously separates adhesions on the inner and outer walls of the medical instrument with a lumen, and adjusts the contact force with the inner and outer walls of the instrument according to the change of the tube diameter of the instrument; a bending adaptation mechanism 6, which is located on the inside of 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.

[0037] During use, the staff puts the instrument into the instrument basket 1 and transfers it to the cleaning pool for soaking in enzyme solution. After soaking in enzyme solution, the faucet of the cleaning pool is connected to the docking pipe 8 in the instrument basket 1. The staff puts the instruments with lumens in the instrument basket 1 into the placement mechanism 4 one by one. The medical instruments in the lumens are vertically clamped by the placement mechanism 4, so that the separation mechanism 5 can separate the adhesions on the inner and outer walls of the lumens when moving in the vertical direction. After multiple instruments with lumens are clamped on the outside of the placement table 3, the staff turns on the faucet, and water flows into the separation mechanism 5 through the docking pipe 8. When separating the adhesions on the inner and outer walls of the lumens, the separation mechanism 5 uses the flowing water to assist the separation mechanism 5 in separating the adhesions on the inner and outer walls of the lumens. Since the diameter of some medical instruments with lumens will gradually decrease, the separation mechanism 5 will adjust the contact force with the inner and outer walls of the instrument according to the change in the diameter of the instrument when moving along the tube wall, thereby reducing the influence of the diameter change on the adhesion separation effect.

[0038] For tubular instruments with a curved shape, the bending adaptation mechanism 6 is set to synchronously adjust the bending curvature of the inner separation cylinder 51 when the distance between the outer brush cylinder 50 and the placement table 3 changes, so that the inner separation cylinder 51 increases the contact area with the inner wall of the tubular cavity when passing through the curved part of the inner wall of the tubular cavity, so as to cooperate with the inner separation cylinder 51 to fully separate the adhesions on the inner wall of the tubular cavity at the curved part, avoid the occurrence of separation dead corners, and by realizing the bending of the inner separation cylinder 51 on the inner wall of the tubular cavity, the impact force of the inner separation cylinder 51 on the inner wall of the tubular cavity when passing through the curved part of the tubular cavity is reduced, thereby reducing the damage to the inner wall of the tubular cavity at the transition part of the curved part of the tubular cavity.

[0039] The placement mechanism 4 includes a fixed plate 40 fixedly connected to the side of the placement table 3, a movable plate 41 is provided below the fixed plate 40, an adjustment groove 42 is opened on the inner wall of the placement table 3, the movable plate 41 is slidably connected to the inner wall of the adjustment groove 42, and a plurality of rubber protrusions 43 are fixedly connected to one end of the movable plate 41 near the adjustment groove 42. The rubber protrusions 43 are clamped with the inner wall of the adjustment groove 42. Airbag clamps 44 are fixedly connected to the inner sides of the fixed plate 40 and the movable plate 41 respectively, and the airbag clamps 44 are C-shaped.

[0040] When the staff places the instrument with a lumen, they insert the two ends of the lumen instrument through the openings of the airbag clamp 44 respectively. The instrument squeezes the airbag clamp 44, causing the airbag clamp 44 to deform. When the airbag clamp 44 deforms, the air pressure inside the airbag clamp 44 also increases. The increased air pressure pushes the airbag clamp 44 to abut against the outside of the instrument, thereby clamping the instrument and keeping the instrument in a vertical position.

[0041] 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, and then adjust the position of the movable plate 41. When the movable plate 41 slides on the inner wall of the adjustment groove 42, the rubber protrusion 43 is squeezed and deformed. When the movable plate 41 moves to a new position, the rubber protrusion 43 relies on its own elasticity to reset, thereby limiting the position of the movable plate 41 again, so that the airbag clamp 44 on the inner side of the movable plate 41 is misaligned with the airbag clamp 44 in the fixed plate 40, so as to cooperate in clamping the two 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.

[0042] The separation mechanism 5 includes an outer brush cylinder 50 and an inner separation cylinder 51. The outer side of the outer brush cylinder 50 is fixedly connected to an air bag column 52. The movable seat 53 is located on the outer side of the air bag column 52. The inner wall of the movable seat 53 is provided with a rotating member 54 that drives the air bag column 52 to rotate on the inner wall of the movable seat 53. The outer side of the movable seat 53 is fixedly connected to a telescopic plate 55. A lifting plate 56 is located on the outer side of the telescopic plate 55. The lifting plate 56 is slidably connected to the inner wall of the placement table 3. The end of the telescopic plate 55 close to the lifting plate 56 is located in the lifting plate 56 and is slidably connected to the inner wall of the lifting plate 56. The end of the telescopic plate 55 close to the lifting plate 56 is fixedly connected to a tension spring 57. The tension spring 57 is fixed to the inner wall of the lifting plate 56. A multi-stage electric telescopic rod 58 is installed on the outer side of the placement table 3. The telescopic end of the multi-stage electric telescopic rod 58 is fixed to the lifting plate 56.

[0043] An airbag column 2 59 is fixedly connected to the outside of the inner separation cylinder 51. A synchronization part 510 is provided between the airbag column 2 59 and the airbag column 1 52 for adjusting the size of the airbag column 2 59 according to the shape change of the airbag column 1 52. A plurality of rubber tubes 511 are fixedly connected to the inner wall of the airbag column 2 59. The rubber tubes 511 are connected to the inner wall of the inner separation cylinder 51. The rubber tubes 511 guide the water flow on the inner wall of the inner separation cylinder 51 into the inner wall of the instrument lumen. When the airbag column 2 59 expands, the rubber tube 511 is made of rubber material and can also be stretched. A flexible cleaning pad 512 is wrapped around the outside of the airbag column 2 59. The flexible cleaning pad 512 is made of microfiber and has a friction coefficient of less than 0.1, which reduces damage to the inner wall of the lumen. A connecting part 513 is provided between the top of the inner separation cylinder 51 and the movable seat 53.

[0044] When separating the adhesions on the surface of the instrument, the inner separation cylinder 51 is placed into the inner wall of the tube cavity through the connecting piece 513, and the outer brush cylinder 50 is placed outside the tube wall of the instrument. The outer wall of the instrument is inserted into the inner side of the outer brush cylinder 50 by squeezing the airbag column 52.

[0045] When separating the adhesions 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, and 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, so that the outer brush tube 50 moves along the outer surface of the instrument, and drives the air bag column 1 52 to rotate back and forth on the inner wall of the moving seat 53 through the rotating member 54, and the air bag column 1 52 drives the outer brush tube 50 to rotate back and forth on the outer surface of the instrument to cooperate with the separation of adhesions on the outer surface of the instrument, and when the moving seat 53 moves in the vertical direction, it drives the inner separation tube 51 to move on the inner wall of the lumen through the connecting member 513, and the inner separation tube 51 drives the flexible cleaning pad 512 to slide on the inner wall of the lumen, and water is injected into the inner wall of the instrument lumen through the rubber tube 511, and the flexible cleaning pad 512 cooperates with the flowing water to separate the adhesions on the inner wall of the instrument lumen soaked in enzyme solution.

[0046] When the outer brush tube 50 moves along the outer surface of the instrument, if the diameter of the instrument tube gradually decreases from top to bottom, the synchronizer 510 inflates the airbag column 1 52, and at the same time, the synchronizer 510 extracts air from the airbag column 2 59, so that the airbag column 1 52 expands and drives the outer brush tube 50 close to the instrument tube wall with reduced size. After the gas in the airbag column 2 59 is extracted, the airbag column 2 59 contracts, thereby reducing the squeezing force of the flexible cleaning pad 512 on the reduced inner wall of the tube cavity, so that when the inner separation tube 51 slides on the inner wall of the tube cavity, the scraping force of the flexible cleaning pad 512 on the inner wall of the tube cavity is reduced.

[0047] When the outer brush cylinder 50 moves in the vertical direction on the outer surface of the instrument, if the instrument tube body has a curved shape, since the instrument is in a posture where the tube body gradually approaches the placement table 3 from top to bottom when installed, when the outer brush cylinder 50 moves along the tube body, under the elastic force of the tension spring 57, the telescopic plate 55 slides on the inner wall of the lifting plate 56, and the telescopic plate 55 drives the moving seat 53 to approach the placement table 3, and the moving seat 53 drives the outer brush cylinder 50 to approach the placement table 3, and when the moving seat 53 moves, the bending adaptation mechanism is triggered. Structure 6, the bending adaptation mechanism 6 controls the bending of the inner separation cylinder 51 on the inner wall of the tubular cavity, so that the inner separation cylinder 51 increases the contact area with the inner wall of the tubular cavity when passing through the curved part of the inner wall of the tubular cavity, so that the inner separation cylinder 51 can fully separate the adhesions on the inner wall of the tubular cavity at the curved 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 tubular cavity, the impact force of the inner separation cylinder 51 on the inner wall of the tubular cavity at the curved part when sliding on the inner wall of the tubular cavity is reduced, and the scraping force on the inner wall of the tubular cavity at the transition part of the curved part is reduced.

[0048] The rotating part 54 includes a gear ring 514 fixedly connected to the outer side of the airbag column 52, a gear plate 515 is engaged with the outer side of the gear ring 514, the gear plate 515 is slidingly 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 screw 517 is rotatably connected to the inner wall of the moving seat 53, the bidirectional 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 screw 517, and the micro motor 518 is installed on the inner wall of the moving seat 53.

[0049] When separating the adhesions on the outside of the instrument, the micro motor 518 drives the bidirectional screw 517 to rotate. Since the transmission block 516 is threadedly connected to the bidirectional screw 517, when the bidirectional screw 517 rotates, it drives the transmission block 516 to move back and forth on the surface of the bidirectional screw 517. The reciprocating movement of the transmission block 516 drives the gear plate 515 to move back and forth on the inner wall of the moving seat 53. When the transmission block 516 moves from one end of the bidirectional screw 517 stroke to the other end, the gear plate 515 will only drive the gear ring 514 to rotate 20°, so that when the transmission block 516 reciprocates on the surface of the bidirectional screw 517, the gear plate 515 drives the gear ring 514 to rotate 20° clockwise and 20° counterclockwise alternately, and then the air bag column 1 52 drives the outer brush tube 50 to rotate 20° clockwise and 20° counterclockwise alternately to switch to cooperate with the adhesions on the outside of the instrument.

[0050] The synchronization part 510 includes a processing box 519 fixedly mounted on the surface of the movable seat 53, the inner wall of the processing box 519 is slidably connected to a piston plate 520, the surface of the piston plate 520 is fixedly connected to a return spring 521, the return spring 521 is mounted on the inner wall of the processing box 519, the bottom end of the processing box 519 is connected to a connecting pipe 1 522, the connecting pipe 1 522 is connected to the airbag column 1 52, the top of the processing box 519 is connected to a connecting pipe 2 523, the end of the connecting pipe 2 523 away from the processing box 519 is connected to the airbag column 2 59, the bottom of the airbag column 2 59 is connected to a temporary airbag 524, and the temporary airbag 524 is flat in its initial state.

[0051] When the diameter of the instrument tube increases, the instrument tube wall squeezes the airbag column 1 52. After the airbag column 1 52 is squeezed, the internal gas enters the processing box 519 through the connecting tube 1 522, so that the air pressure in the processing box 519 increases. The increased air pressure pushes the piston plate 520 to slide upward on the inner wall of the processing box 519. The piston plate 520 compresses the return spring 521, so that the piston plate 520 injects the gas in the processing box 519 into the inner wall of the airbag column 2 59 through the connecting tube 2 523, so that the airbag column 2 59 expands. Since the size of the airbag column 1 52 is larger than that of the airbag column 2 59, when the size of the airbag column 1 52 is reduced, the gas injected into the airbag column 2 59 The gas in the airbag column 2 59 will cause the expansion range of the airbag column 2 59 to be larger. In order to avoid the large expansion range of the airbag column 2 59 causing excessive squeezing pressure between the flexible cleaning pad 512 and the inner wall of the tube cavity, the present application is connected to a temporary storage airbag 524 with an initial flat state above the airbag column 2 59. When the air pressure in the airbag column 2 59 increases, the gas will be injected into the flat temporary storage airbag 524, causing the temporary storage airbag 524 to expand. When the outer brush tube 50 slides along the surface of the instrument, if the diameter of the instrument tube increases, the flexible cleaning pad 512 on the inner wall of the tube cavity also expands outward to close to the inner wall of the tube cavity, so as to cooperate with and improve the separation effect of adhesions on the inner wall of the tube cavity.

[0052] When the diameter of the instrument tube 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 airbag column 1 52, so that the airbag column 1 52 expands and makes the outer brush tube 50 close to the outside of the instrument. At the same time, when the piston plate 520 slides downward, the gas in the airbag column 2 59 and the temporary airbag 524 will be extracted, thereby reducing the size of the airbag column 2 59, and preventing the inner separation tube 51 from sliding on the inner wall of the tube cavity, and the friction between the flexible cleaning pad 512 and the inner wall of the tube cavity is too large, causing damage to the inner wall of the tube cavity.

[0053] The connecting piece 513 includes a support tube 525 fixedly connected to the top of the processing box 519, and a connecting box 526 fixedly connected to the top of the support tube 525. The support tube 525 and the connecting box 526 are located on the outside of the connecting tube 2 523. The bottom of the connecting box 526 is connected to a silicone tube 527. The minimum bending radius of the silicone tube 527 is 10 cm, which matches the curvature of common tubular instruments. The end of the silicone tube 527 away from the connecting box 526 is connected to the inner separation tube 51.

[0054] When the staff places the instrument, since the silicone tube 527 is made of silicone, after placing the tubular instrument inside the airbag clamp 44, the staff can bend the silicone tube 527 to place the inner separation cylinder 51 into the inner wall of the instrument lumen.

[0055] When the movable seat 53 moves in the vertical direction, the movable seat 53 drives the connecting box 526 to move in the vertical direction through the supporting tube 525, and the connecting box 526 drives the inner separation tube 51 to move in the vertical direction through the silicone tube 527. The silicone tube 527 is made of silicone material and has good bending flexibility, so it can also bend when following the moving seat 53 to move in the vertical direction.

[0056] A water storage box 7 is fixedly connected to the top of the placement table 3, and a docking pipe 8 is connected to 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 pipes 9 are connected to the outside of the water storage box 7. The plurality of water pipes 9 are respectively connected to the corresponding connection boxes 526, and the water pipes 9 are arranged obliquely.

[0057] When the faucet is turned on, 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 supply pipe 9. The liquid in the connecting box 526 is injected into the inner separation cylinder 51 through the silicone tube 527, and is injected into the inner wall of the tube cavity through the rubber tube 511. When the flexible cleaning pad 512 separates the adhesions on the inner wall of the tube cavity, the flowing water assists the flexible cleaning pad 512 in cleaning the adhesions on the inner wall of the tube cavity, thereby improving the separation effect.

[0058] The bending adaptation mechanism 6 includes a connecting plate 60 installed on the outside of one end of the silicone tube 527 close to the inner separation cylinder 51, and a bending spring 61 is installed between the connecting plate 60 and the top of the inner separation cylinder 51. An adjusting part 62 is provided on the outside of the placement table 3 to adjust the bending curvature of the bending spring 61 according to the moving position of the outer brush cylinder 50.

[0059] When the outer brush cylinder 50 passes through the curved transition of the instrument, the movable seat 53 moves toward the placement table 3 under the tension of the tension spring 57, and the movement of the movable seat 53 triggers the adjusting member 62, and the adjusting member 62 drives the inner separation cylinder 51 to rotate relative to the silicone tube 527, that is, the inner separation cylinder 51 approaches the placement table 3, and the inner separation cylinder 51 drives the bending spring 61 to bend, 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, so as to cooperate with the inner flexible cleaning pad 512 to fully separate the adhesions on the inner wall of the lumen at the curved part, avoid the occurrence of 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 instrument is reduced, and the scraping force on the inner wall of the curved transition of the lumen is reduced.

[0060] The adjusting member 62 includes an electromagnet 63 mounted on the surface of the placing table 3. There are multiple electromagnets 63 and they are vertically distributed. A trigger block 64 is provided on the outside of each electromagnet 63. A trigger rod 65 is fixedly connected to the outside of the trigger block 64. A sliding groove 66 is provided on 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 installed 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. The trigger rod 65 A compression spring 611 is fixedly connected to the outside. When the pressure rod 69 does not squeeze 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 button switch 68 is installed on the inner wall of the sliding groove 66. The normally open 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 pressure rod 69 is fixedly connected to the side of the movable seat 53 close to the trigger block 64, and an iron sheet 610 is fixedly connected to the inner wall of the inner separation cylinder 51.

[0061] The normally open push button switch 68 is a mature existing technology on the market. It is usually composed of a button cap, a spring, a bridge-type moving contact, a static contact and a shell. Its principle is: when it is not pressed in the normal state, the moving contact and the static contact are separated, and the circuit is in the disconnected state; when the button cap is pressed, the moving contact moves downward under the action of pressure and contacts the static contact to close the circuit; when the button cap is released, the spring will restore the moving contact to its initial position, separate from the static contact, and the circuit will return to the disconnected state.

[0062] Medical devices with tubular lumens are made of various materials, most of which are made of titanium, titanium alloys and polymer materials. Titanium and titanium alloys are non-magnetic materials and will not shield the magnetic field of the electromagnet 63. They are widely used in some medical devices that have high requirements for the magnetic field environment, such as interventional devices guided by magnetic resonance imaging; polymer materials will not shield the magnetic field, so that the magnetic field generated by the electromagnet 63 can attract the iron sheet 610 to adjust the bending amplitude of the separation cylinder 51 in the inner wall of the tubular lumen.

[0063] When the outer brush cylinder 50 slides at the bending part of the instrument tube body, the outer brush cylinder 50 approaches the placement table 3, and when the tension spring 57 drives the telescopic plate 55 to move toward the placement table 3, the telescopic plate 55 drives the moving seat 53 to move, and the moving seat 53 drives the pressure rod 69 to approach the placement table 3, and the pressure rod 69 contacts and squeezes 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 button switch 68, so that the circuit where the electromagnet 63 is located is closed. After the electromagnet 63 is energized, it generates a magnetic field, thereby attracting the iron sheet 610 on the inner wall of the inner separation cylinder 51, so that the iron sheet 610 drives the inner separation cylinder 51 to approach the electromagnet 63, thereby causing the bending spring 61 to bend.

[0064] The trigger rod 65 is in contact with the sliding key of the sliding rheostat 67. As the moving seat 53 gets closer to the placement table 3, the trigger rod 65 slides farther on the inner wall of the sliding groove 66, and the trigger rod 65 drives the sliding key of the sliding rheostat 67 to move a greater distance. The connection method between the trigger rod 65 and the sliding rheostat 67 is as follows: the closer the trigger rod 65 drives the sliding key to the placement table 3, the smaller the resistance of the sliding rheostat 67, thereby increasing the current in the circuit where the electromagnet 63 is located and the stronger the magnetic field generated by the electromagnet 63. Specifically, for every 1 mm movement of the trigger rod 65, the resistance of the sliding rheostat 67 decreases. Lower by 0.5Ω, thereby linearly increasing the suction force of the electromagnet 63, so that the inner separation cylinder 51 located in the lumen of the instrument has a larger movement amplitude at one end of the iron sheet 610 installed, thereby increasing the contact area between the inner separation cylinder 51 and the inner wall of the lumen when passing through the curved part of the inner wall of the lumen, so as to cooperate with the flexible cleaning pad 512 to fully separate the adhesions on the inner wall of the lumen at the curved part, avoid the occurrence of separation dead angles, and realize the bending of the inner separation cylinder 51 on the inner wall of the lumen, thereby reducing the impact force of the inner separation cylinder 51 on the inner wall of the lumen, and reducing the scraping force on the inner wall of the lumen at the curved transition part.

[0065] Example 2

[0066] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a support plate 20 is fixedly connected to the outer side 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 tubular cavity can pass through the brush plate 21, so that the brush plate 21 cleans the port of the instrument, thereby improving the effect of separating adhesions from the instrument.
