Description

Technical Field

[0001] This invention relates to the field of medical examination technology, specifically to a rectal protection device for colonoscopy. Background Technology

[0002] A colonoscopy is an examination in which a colonoscope is inserted through the anus into the rectum, colon, and finally the cecum to observe changes in the large intestine mucosa. The entire large intestine is viewed through a "camera" at the tip of the colonoscope's flexible tube. Typically, the colonoscope also has channels inside for placing instruments, allowing for endoscopic tissue sampling for pathological examination and even procedures such as lesion removal.

[0003] Utility model patent CN210784726U discloses a rectal protection device for colonoscopy, including an air inlet tube. One end of the air inlet tube is fixedly provided with a first flexible connector, and the other end of the air inlet tube is provided with a rectal protection mechanism. The rectal protection mechanism includes a rectal protection sleeve, the bottom of which is fixedly provided with an anal restrictive edge. The cross-sectional shape of the anal restrictive edge is set as trapezoidal. The top of the rectal protection sleeve is fixedly provided with an internal fixed air-inflating bladder. The bottom of the internal fixed air-inflating bladder is provided with an air inlet. Both the rectal protection sleeve and the anal restrictive edge are provided with air delivery channels.

[0004] The shortcomings of the existing technical solution are as follows: This utility model, by setting a rectal protection mechanism, inserts the colonoscope into the rectal protection sleeve to deliver lubricant to the colonoscope. Although this can effectively reduce the damage caused by repeated friction between the colonoscope and the rectum and anus, it cannot adjust the amount of lubricant applied or evenly spread the lubricant on the endoscope. This results in too much or too little lubricant on the endoscope. Too much lubricant will affect the doctor's judgment of the examination results, while too little will not meet the lubrication requirements. Furthermore, areas on the endoscope that have not been evenly coated cannot be recoated, thus limiting the lubrication effect. Summary of the Invention

[0009] Furthermore, a speed-regulating fixing head is slidably mounted on the speed-regulating sliding frame, and a speed-regulating reset spring is fixedly mounted between the speed-regulating fixing head and the speed-regulating sliding frame. The speed-regulating fixing head is slidably engaged with the groove on the speed-regulating rod. The speed-regulating gear meshes with speed-regulating stepping gear one, speed-regulating stepping gear two, speed-regulating stepping gear three, speed-regulating stepping gear four, and speed-regulating stepping gear five, respectively.

[0029] A pressurizing assembly 3 is fixedly installed on the speed-regulating rotating shaft 214. The pressurizing assembly 3 includes a pressurizing rotating rod 301 fixedly installed on the speed-regulating rotating shaft 214. A pressurizing ring 302 is hinged on the pressurizing rotating rod 301.

The coating and patching ring 102 is disposed between the coating ring 103 and the coating and patching pipe 101.

[0030] This invention discloses a rectal protection device for colonoscopy, the working principle of which is as follows: First, the endoscope is inserted into the rectum through the through holes on the smearing ring 103 and the smearing and spreading ring 102. The smearing motor 107 is turned on, driving the smearing gear 108 to rotate. The smearing gear 108 drives the smearing toothed ring 106 to rotate. The smearing toothed ring 106 drives the smearing meshing gear 117 to rotate. The smearing meshing gear 117 drives the smearing small worm gear 105 to rotate. The smearing small worm gear 105 meshes with the smearing large worm gear 115 rotatably mounted on the smearing rotating shaft 104, thereby causing the smearing rotating shaft 104 to slide within the smearing transmission gear 114, the smearing bearing 112, and the smearing bearing 118. At the same time, the rotation of the smearing meshing gear 117 drives the smearing rotating rod 121, causing the smearing transmission gear 113 to rotate. The rotation of the smearing transmission gear 113 drives the smearing transmission gear 114, thereby causing the smearing rotating shaft 104 to rotate and slide simultaneously.

[0031] When the coating rotating shaft 104 contacts the speed regulating rotating shaft 208, the coating rotating shaft 104 drives the speed regulating rotating shaft 208 to rotate. The rotation of the speed regulating rotating shaft 208 causes the speed regulating stepper gears 209, 210, 211, 212, and 213 to rotate. At the same time, the coating fixing plate 120 slides on the speed regulating slide bar 201 and compresses the speed regulating spring 202, causing the speed regulating sliding frame to rotate. 215 drives the speed regulating gear 203 to slide on the second speed regulating rotating shaft 214. The speed regulating gear 203 slides and meshes with the first speed regulating stepping gear 209, the second speed regulating stepping gear 210, the third speed regulating stepping gear 211, the fourth speed regulating stepping gear 212, and the fifth speed regulating stepping gear 213 on the first speed regulating rotating shaft 208. Since the number of teeth on the gears on the first speed regulating rotating shaft 208 is different, the speed regulating gear 203 drives the second speed regulating rotating shaft 214 to rotate by different amplitudes.

[0032] When the speed control handle 204 slides within the speed control lever 205, causing the speed control lever 205 to rotate, the rotation of the speed control lever 205 aligns the groove on the speed control lever 205 with the speed control fixing head 206. When the speed control fixing head 206 engages with the groove on the speed control lever 205, the speed control gear 203 is briefly limited. At this time, the speed control gear 203 meshes with any gear on the first speed control rotating shaft 208, causing the speed control gear 203 to rotate and drive the second speed control rotating shaft 214 to rotate, achieving different rotation amplitudes of the second speed control rotating shaft 214; when the speed control spring 2... When the speed adjustment head 206 retracts to the predetermined position, under the elastic force of the speed adjustment spring 202, the speed adjustment fixing head 206 disengages from the groove on the speed adjustment rod 205, causing the speed adjustment sliding frame 215 to continue moving, so that the speed adjustment gear 203 meshes with the gear on another speed adjustment rotating shaft 208. The above steps are repeated to complete different rotation amplitudes of the second speed adjustment rotating shaft 214. The rotation of the second speed adjustment rotating shaft 214 causes the pressure rotating rod 301 to drive the pressure ring 302 to rotate at different amplitudes. The different rotation amplitudes of the pressure ring 302 realize the control of the amount of lubricant sprayed.

[0033] The pressure ring 302 slides on the pressure fixing block 303. When the pressure ring 302 moves to a predetermined position, it draws the lubricant in the pressure storage tank 305 into the pressure housing 304. When the pressure ring 302 moves to another predetermined position, it transports the lubricant drawn into the pressure housing 304 along the pipeline to the coating ring 103. The coating ring 103 performs the initial coating on the mirror body. The coating and smoothing ring 102 is rotatably mounted on the coating rotation shaft 104. When the coating rotation shaft 104 slides, it causes the coating and smoothing ring 102 to slide and uniformly process the lubricant that has been initially applied to the mirror body by the coating ring 103.

[0034] When the lubricant on the microscope body is uneven, the first application motor 107 is turned off and the second application motor 110 is started. The second application motor 110 drives the large application gear 109, which in turn drives the application and touch-up tube 101 to rotate a certain angle to reapply lubricant to the unevenly applied areas of the microscope body. At the same time, when the second application rotating plate 119 and the first application rotating plate 116 rotate, the application meshing gear 117 meshes with the application gear ring 106, which in turn causes the small application worm gear 105 and the first application transmission gear 113 to rotate. The small application worm gear 105 meshes with the large application worm gear 115, which is rotatably mounted on the application rotating shaft 104, which in turn causes the application rotating shaft 104 to slide within the second application transmission gear 114, the first application bearing 112, and the second application bearing 118.

[0035] Simultaneously, the rotation of the coating meshing gear 117 drives the coating rotating rod 121, causing the coating transmission gear one 113 to rotate. The rotation of the coating transmission gear one 113 drives the coating transmission gear two 114, which in turn causes the coating rotating shaft 104 to rotate and slide. When the coating rotating shaft 104 contacts the speed regulating rotating shaft one 208, the coating rotating shaft 104 drives the speed regulating rotating shaft one 208 to rotate. The rotation of the speed regulating rotating shaft one 208 causes the speed regulating stepper gears one 209, two 210, three 211, four 212, and five 213 to rotate. As the speed is adjusted, the fixing plate 120 slides on the speed regulating slide bar 201 and compresses the speed regulating spring 202, causing the speed regulating slide frame 215 to drive the speed regulating gear 203 to slide on the second speed regulating rotating shaft 214. The speed regulating gear 203 slides and meshes with the first speed regulating stepping gear 209, the second speed regulating stepping gear 210, the third speed regulating stepping gear 211, the fourth speed regulating stepping gear 212, and the fifth speed regulating stepping gear 213 on the first speed regulating rotating shaft 208, respectively. Since the number of teeth on the gears on the first speed regulating rotating shaft 208 is different, the speed regulating gear 203 drives the second speed regulating rotating shaft 214 to rotate by different amplitudes.

[0036] When the speed control handle 204 slides within the speed control lever 205, the speed control lever 205 rotates. This rotation aligns the groove on the speed control lever 205 with the speed control fixing head 206. When the speed control fixing head 206 engages with the groove on the speed control lever 205, the speed control gear 203 is briefly limited. At this time, the speed control gear 203 meshes with any gear on the first speed control rotating shaft 208, causing the speed control gear 203 to rotate and drive the second speed control rotating shaft 214 to rotate, achieving different rotation amplitudes of the second speed control rotating shaft 214. When the speed control spring 202 contracts... When the speed reaches the predetermined position, the speed regulating fixed head 206 disengages from the groove on the speed regulating rod 205 under the elastic force of the speed regulating spring 202, causing the speed regulating sliding frame 215 to continue moving so that the speed regulating gear 203 meshes with the gear on another speed regulating rotating shaft 208. The above steps are repeated to complete different rotation amplitudes of the second speed regulating rotating shaft 214. The rotation of the second speed regulating rotating shaft 214 drives the pressure rotating rod 301, which in turn drives the pressure ring 302 to rotate at different amplitudes. The different rotation amplitudes of the pressure ring 302 realize the control of the amount of lubricant sprayed.
