DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0030] See attached Figure 1-7 , an ultrasonic cleaning device for gastroenteroscopic instruments, comprising a cleaning box 1, an inner box is arranged in the cleaning box 1, a lifting bracket 2 is arranged in the inner box, a plurality of scraper rings 3 for the gastroenteroscopic hose to pass through are arranged on the outer wall of the lifting bracket 2, a wiping soft sleeve is arranged inside the scraper ring 3 to prevent the hose from being worn and damaged when moving in the scraper ring 3, the wiping soft sleeve can be completely wrapped around the outer wall of the hose to improve the cleaning ability of the hose surface, a plurality of scraper rings 3 are arranged in a spiral ascending manner, so that the hose passing through the scraper ring 3 is in a three-dimensional distribution state, so as to reduce the contact between the hose and the cleaning box 1 and reduce the cleaning dead angle, a clamping mechanism 4 for clamping the end of the gastroenteroscopic hose is arranged in the cleaning box 1 to pull the gastroenteroscopic hose to move along the inner wall of the scraper ring 3, and the gastroenteroscopic hose can do lifting movement and be fully pulled and scraped during the cleaning process, thereby improving the cleaning effect.

[0031] The gastroenteroscope hose is prone to various sticky dirt during use. Although the traditional ultrasonic cleaning method can use the cavitation effect generated by high-frequency sound waves in the liquid to remove some pollutants, the cleaning effect is not ideal for stubborn sticky pollutants. In the cleaning process, the gastroenteroscope hose is first passed through a plurality of scraper rings 3 from bottom to top in sequence, and then its end is clamped by the clamping mechanism 4. During cleaning, the lifting bracket 2 and the scraper ring 3 drive the gastroenteroscope to do reciprocating lifting and lowering movements, and at the same time, the clamping mechanism 4 pulls the end of the gastroenteroscope hose to move, so that the hose moves along the scraper ring 3, so that the hose can be fully pulled and scraped during the cleaning process, thereby effectively removing sticky dirt and improving the cleaning effect. Compared with the stirring method, the pulling and scraping cleaning method can avoid damage to the surface of the hose and the precision instrument at its end, greatly improving the safety of cleaning;

[0032] Furthermore, high-frequency ultrasonic cleaning (≥40kHz) is selected. The cavitation bubbles generated by high-frequency ultrasonic cleaning are smaller, more evenly distributed, and have a milder impact force. It is suitable for cleaning precision parts such as optical lenses and coated instruments. It can significantly reduce the risk of surface scratches or coating peeling. It also uses high-frequency sound waves to produce cavitation effects in liquids, which can effectively remove pollutants.

[0033] Furthermore, the present application also proposes that a traction mechanism is provided in the cleaning box 1, and the traction mechanism includes a first swing arm 51, and a connecting rod 52 is provided at one end of the first swing arm 51. The end of the connecting rod 52 away from the first swing arm 51 is connected to the clamping mechanism 4 to form traction on the end of the gastrointestinal endoscope hose. When high-frequency ultrasound is selected for cleaning, experiments have shown that when chrome-plated instruments are cleaned in ultrasound for more than 10 minutes, the risk of coating shedding increases, and its high-intensity energy may cause damage to the surface of precision instruments such as endoscope lens coatings and optical elements. Therefore, when the gastrointestinal endoscope is lifted and cleaned, the first swing arm 51 is intermittently swung upward, and the connecting rod 52 further drives the clamping mechanism 4 to swing upward intermittently, providing an upward traction force for the clamping mechanism 4, while driving the end of the gastrointestinal endoscope hose to intermittently move upward out of the water surface in the cleaning box 1, so that the cleaning of other positions of the hose is maintained for a sufficient time, while reducing the time for the instruments at the end of the hose to be cleaned in ultrasound, and damage to the instruments at the end of the hose can be avoided when the gastrointestinal endoscope is cleaned for a long time, thereby greatly improving the service life of the gastrointestinal endoscope.

[0034] A skirt 21 is provided at the bottom of the lifting bracket 2, and an arc-shaped slot 22 is provided in the skirt 21. A slider 23 is slidably connected in the arc-shaped slot 22, and an arc-shaped spring 24 is provided in the arc-shaped slot 22 to abut against the slider 23 to provide necessary elastic support. The slider 23 is connected to a scraper ring 3 at the bottom, and a screw 31 for fixing the gastrointestinal endoscope hose is threadedly connected on the scraper ring 3, so as to drive the gastrointestinal endoscope hose to reset when the hose is not subjected to traction. When the end of the hose is pulled during the cleaning process, the hose moves along the scraper ring 3 The scraper sleeve 3 at the bottom will move with the movement of the hose, and make the slider 23 move along the arc groove 22. When the hose is not subjected to traction, the slider 23 will reset in the arc groove 22 under the elastic support of the arc spring 24. At this time, the scraper sleeve 3 at the bottom drives the hose to reset, and intermittently pulls the end of the hose to make the hose reciprocate in the scraper sleeve 3. At this time, the surface of the hose can be scraped multiple times, which can effectively remove adherent dirt and prevent incomplete cleaning.

[0035] A plurality of expansion mechanisms are arranged in the cleaning box 1, and the expansion mechanisms include a second swing arm 61, and one end of the second swing arm 61 is connected to a scraper sleeve 3, so that when the traction mechanism pulls the end of the gastroenteroscope hose, the scraper sleeve 3 expands outward to increase the distance that the gastroenteroscope hose is pulled. By utilizing the second swing arm 61 to drive the scraper sleeve 3 thereon to expand outward, the distance that the gastroenteroscope hose is pulled is increased, which helps the cleaning liquid to fully contact various parts of the gastroenteroscope hose and can prevent some parts of the hose from not passing through the scraper sleeve 3, thereby effectively reducing cleaning dead angles, making the cleaning of the hose more thorough and improving the cleaning effect.

[0036] A fixing plate 7 is provided on the top of the cleaning box 1, and a cylinder 8 is provided on the fixing plate 7. The bottom of the cylinder 8 passes through the fixing plate 7 and is connected to a fixing frame 25. The fixing frame 25 is fixed in the lifting bracket 2 to drive the lifting bracket 2 to perform lifting motion. When the cylinder 8 works, the lifting bracket 2 performs lifting motion, which further enables the gastroenteroscope to perform lifting motion in the cleaning box 1, thereby effectively improving the cleaning effect.

[0037] The end of the first swing arm 51 away from the connecting rod 52 is rotatably connected to the bottom of the fixed plate 7, and the first swing arm 51 is rotatably connected with the first connecting rod 53, and the end of the first connecting rod 53 away from the first swing arm 51 is rotatably connected with the first connecting block 54. The bottom of the first connecting block 54 is provided with a first vertical rod 55, and a plurality of strip grooves 26 are opened in the fixing frame 25. The first vertical rod 55 passes through one of the strip grooves 26 and is connected with a first limiting plate 56. The diameter of the first limiting plate 56 is larger than the width of the strip groove 26, which is convenient for resetting the device. There is a movement interval between the various connecting structures to prevent the hose from being suddenly damaged by a strong pulling force. When the lifting bracket 2 is lifting, the fixing frame 25 pushes the bottom of the first connecting block 54 upward, further making the first connecting block 54 move upward. At this time, the first connecting rod 53 will push the first swing arm 51 to move upward. When the first swing arm 51 pulls the hose upward through the clamping mechanism 4, there is no need to install a driving device separately, which greatly reduces the cost of the equipment.

[0038] A second connecting rod 62 is rotatably connected inside the second swing arm 61, and the second connecting rod 62 is rotatably connected to the second connecting block 63 at one end away from the second swing arm 61. A second vertical rod 64 is provided at the bottom of the second connecting block 63. The second vertical rod 64 has one of the strip grooves 26 and is connected to a second limiting plate 65. The diameter of the second limiting plate 65 is larger than the width of the strip groove 26 to facilitate resetting the device. A movement interval is left between the connecting structures to prevent the hose from being damaged by a strong pulling force. When the lifting bracket 2 is lifting, the fixing frame 25 pushes the second connecting block 63 upward, further allowing the second connecting rod 62 to push the second swing arm 61 upward. When the second swing arm 61 drives the scraper ring 3 to expand outward, there is no need to install additional driving equipment, which greatly reduces the cost of the equipment.

[0039] The clamping mechanism 4 includes a base plate 41, on which a sliding frame 42 is provided. A pair of clamping plates 43 are slidably connected in the sliding frame 42. A threaded rod 44 is rotatably connected in the base plate 41. The threaded rod 44 penetrates the pair of clamping plates 43 and is threadedly connected thereto. A knob 45 is provided at the end of the threaded rod 44. When clamping, the end of the hose is placed between the pair of clamping plates 43, and then the knob 45 is rotated. At this time, the threaded rod 44 rotates, causing the pair of clamping plates 43 to move relative to each other and clamp the hose. The opposing surfaces of the two clamping plates 43 are provided with cushions to reduce the hard squeezing force on the hose and prevent the hose from being squeezed and damaged.
