Description

Technical Field

[0001] The present invention belongs to the technical field of endoscope equipment, and in particular relates to a digestive endoscope auxiliary device. Background Art

[0002] A digestive endoscope is a medical device that uses endoscopic technology to examine, diagnose, and treat the digestive system. It uses a slender endoscope tube equipped with a light source and camera to transmit real-time images of the digestive tract to a monitor, helping doctors observe lesions in the esophagus, stomach, intestines, and other areas. In addition to its inspection capabilities, digestive endoscopes can also perform biopsies, hemostasis, and foreign body removal.

[0003] The Chinese patent application number 202410692589.X discloses a digestive endoscope with a robotic arm. The digestive endoscope with a robotic arm comprises: the fixing frame is fixedly connected to the inside of the mounting shell near the middle position, one side of the fixing frame is fixedly connected to a telescopic rod, the telescopic end of the telescopic rod is installed with a connector through a mounting plate, the other end of the connector is installed with a steel wire, one side of the inside of the mounting shell is fixedly connected to a support ring, the other end of the support ring is fixedly connected to a reset spring, one side of the mounting shell is installed with an auxiliary tube through a mounting ring, and the other end of the auxiliary tube is installed with an angle swing head through a mounting head. The digestive endoscope with a robotic arm provided by this patent combines clamping and cutting with a visual endoscope through this structure, thereby increasing the function of the digestive endoscope, and at the same time drives the endoscope tube to adjust its angle through a flexible angle swing head, replacing the traditional mechanical connection, avoiding the wear of the mechanical connection and thus increasing stability.

[0004] When using a digestive endoscope, a positioning device is usually worn in the patient's mouth to facilitate the use of the endoscope without harming the patient. However, if the positioning device is too loose, the accuracy of endoscopic detection cannot be guaranteed, and if the positioning is too tight, the movement of the endoscope tube will be hindered, which depends entirely on the experience of medical staff. The operation is complicated and difficult to handle quickly and flexibly. At the same time, some auxiliary components are discarded after one use and cannot be quickly recycled, resulting in serious waste. When disassembling the positioning device, it is usually removed directly from the head, which is not only uncomfortable but also easy for saliva and foreign matter produced by the positioning device to drip onto the patient's face. Summary of the Invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a digestive endoscope auxiliary device and method. The present invention cooperates with the positioning threaded tube, the adjustment block, the elastic mechanism, and the threaded ring, so that the endoscope tube can always be kept in the middle as much as possible during the movement detection of the endoscope tube, thereby improving the detection accuracy without hindering the movement of the endoscope tube. At the same time, the endoscope tube can be quickly adjusted when it is necessary to temporarily stop the detection. The endoscope tube can be quickly limited and fixed with one hand, so that the endoscope tube is quickly fixed in the middle position, thereby avoiding the twisting of the endoscope tube and further improving the detection accuracy; the present invention can realize rapid adjustment of both mobile detection and temporary fixation through the structural design of the adjustment block, while ensuring the smooth operation of the endoscope tube and avoiding jamming; the present invention can not only movably press the endoscope tube to effectively limit the pressing endoscope tube through the structural design of the elastic mechanism, but also quickly adjust the elastic force of each elastic mechanism according to the actual operation angle, so that the endoscope tube can be kept in the middle as much as possible, thereby improving the detection accuracy. The present invention cooperates with the cover plate and the elastic strap, which can not only quickly and effectively fix the head and achieve a suitable tightening scale, but also quickly disassemble the elastic strap without taking it off the head, thereby improving the patient's comfort and allowing the elastic strap to be reused. It can also prevent saliva and foreign matter produced by the oral tube from dripping onto the patient's face.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A digestive endoscopy auxiliary device comprises a cover plate, the middle of the cover plate is open, and both ends of the opening are fixedly connected to an oral tube and a positioning threaded tube, and an endoscope tube is inserted into the oral tube and the positioning threaded tube; an elastic band is installed at both ends of the cover plate;

[0008] The wall of the positioning threaded tube is uniformly provided with a plurality of adjustment grooves in an annular direction, and a rotating rod is fixedly provided in the middle of each adjustment groove; an adjustment block is rotatably connected to the rotating rod; a threaded ring is screwed onto the positioning threaded tube; a support ring is fixedly connected to the outer periphery of the positioning threaded tube on one side of the threaded ring and away from the cover plate, and the support ring is connected to one end of the adjustment block via an elastic mechanism;

[0009] When the threaded ring is located outside the rotating rod, the end of the adjusting block close to the support ring presses the endoscope tube; when the threaded ring is located outside the end of the adjusting block away from the support ring, the end of the adjusting block away from the support ring presses the endoscope tube.

[0010] Furthermore, the adjustment block includes a positioning protrusion, a rotating block and a limiting protrusion that are connected to each other in sequence; the protruding direction of the positioning protrusion is toward the outside of the positioning threaded tube, and the protruding direction of the limiting protrusion is toward the inside of the positioning threaded tube; a rotating hole is opened on the rotating block, and the rotating hole is rotatably connected to the corresponding rotating rod.

[0011] Furthermore, the protruding direction of the positioning protrusion has a first inclined surface, which is inclined toward the outside of one end of the positioning threaded tube close to the cover plate; the protruding direction of the limiting protrusion has two second inclined surfaces, and the two second inclined surfaces form a protrusion.

[0012] Furthermore, avoidance grooves are provided on the outer sides of the connections between the rotating block and the positioning protrusion and the limiting protrusion.

[0013] Furthermore, a first pressing surface is provided at the connection point of the two second inclined surfaces; and a second pressing surface is provided at the inner end portion of the positioning protrusion close to the cover plate.

[0014] Furthermore, a plurality of fixing rods are evenly fixed on the inner side of the support ring, and the fixing rods are fixedly connected to the outer wall of the positioning threaded tube; the fixing rods and the adjustment grooves are alternately arranged.

[0015] Furthermore, the elastic mechanism includes a pressure spring, one end of which is fixedly connected to the adjustment block, and the other end of which is fixedly connected to a T-shaped slot, an adjusting screw being provided on the T-shaped slot, and one end of which is fixedly connected to a rotating disk, and the rotating disk is located inside the T-shaped slot and is rotatably connected to the T-shaped slot;

[0016] The support ring is evenly provided with a plurality of threaded holes, and the threaded holes are threadedly connected to the corresponding adjusting screws.

[0017] Furthermore, one end of the elastic band is fixedly connected to a clamping plate, and a plurality of triangular clamping blocks are evenly arranged on both sides of the side wall of the other end.

[0018] Furthermore, slots are provided at both ends of the cover plate, and two rotating slots are symmetrically provided on one of the slots and the notch close to the side of the positioning threaded tube. A roller is rotatably connected to each rotating slot through a rotating shaft, and an abutment plate is fixedly connected to the side wall of the roller; the roller is movably abutted against the side wall of the elastic band; one end of the elastic band with a triangular clamping block passes through the slot with two rollers, and one end of the elastic band with a clamping plate passes through the other slot.

[0019] A method for operating using the above-mentioned digestive endoscopy auxiliary device comprises the following steps:

[0020] S1. First, insert the oral tube into the mouth, then pass one end of the elastic band with the clamping plate through one of the slots. After passing through, lay the clamping plate flat and abut against the cover plate. Pass the elastic band with the triangular clamping block around the skull and pass it through the other slot and tighten it. Then loosen the elastic band to engage the triangular clamping block with the abutment plate.

[0021] S2. Insert the endoscope tube into the positioning threaded tube for inspection. When it is necessary to stop, rotate the threaded ring so that the end of the adjustment block away from the support ring presses against the endoscope tube to achieve temporary fixation.

[0022] S3. After the inspection is completed, pull the elastic strap with the card plate and adjust the card plate so that the card plate passes back through the corresponding slot and detaches from the cover plate to achieve quick unbinding. At the same time, pull one end of the elastic strap with the triangular card block to achieve quick recovery of the elastic strap.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention cooperates with the positioning threaded tube, the adjustment block, the elastic mechanism, and the threaded ring, so that the endoscope tube can always be kept in the middle as much as possible during the movement of the endoscope tube for detection, thereby improving the detection accuracy without hindering the movement of the endoscope tube. At the same time, it can also quickly adjust the endoscope tube when it is necessary to temporarily stop the detection. It can be quickly limited and fixed with one hand, so that the endoscope tube is quickly fixed in the middle position, thereby avoiding the endoscope tube from twisting and further improving the detection accuracy. Specifically, when it is necessary to move the detection, the endoscope tube is inserted into the positioning threaded tube, and under the joint action of multiple elastic mechanisms, the adjustment block and one end close to the support ring press against the endoscope tube, thereby effectively limiting the endoscope tube and keeping the endoscope tube as much as possible. The endoscope tube can be kept in the middle position accurately, thereby making the visual detection picture of the endoscope tube more useful for reference and improving the detection accuracy of the endoscope tube. At the same time, since the elastic mechanism is elastically abutted, it will not hinder the movement of the endoscope tube, thereby improving the smoothness of the movement of the endoscope tube. At the same time, when the endoscope tube needs to be temporarily fixed for detection, it is only necessary to rotate the positioning threaded tube with one hand to make the positioning threaded tube continuously press down one end of the adjustment block, and finally make the adjustment block and the end away from the support ring press against the fixed endoscope tube for temporary fixation, so that the endoscope tube can be quickly limited and fixed by one-hand operation, so that the endoscope tube can be quickly fixed in the middle position, thereby avoiding twisting of the endoscope tube, thereby facilitating the visual picture detection and sampling work of fixed angles, reducing human detection errors, and further improving detection accuracy.

[0025] (2) The present invention can realize two kinds of rapid adjustment, namely, mobile detection and temporary fixation, through the structural design of the adjustment block, while ensuring the smooth operation of the endoscope tube and avoiding jamming. Specifically, when mobile detection is required, the threaded ring is placed on the outside of the rotating rod. At this time, the threaded ring is in the middle area and is not subjected to force on the adjustment block. Therefore, the adjustment block is only subjected to the force of the elastic mechanism, and only the limiting protrusion limits the movement of the endoscope tube. At this time, the endoscope tube can be moved for mobile detection. When temporary fixation is required, the threaded ring is rotated with one hand so that the threaded ring continuously squeezes the first inclined surface, and finally multiple positioning protrusions limit and fix the endoscope tube. At this time, due to the relationship between the rotating hole and the corresponding rotating rod, the limiting protrusion will reversely release the limiting effect of the endoscope tube, thereby realizing two kinds of rapid adjustment, namely, mobile detection and temporary fixation. At the same time, through the structural design of the two second inclined surfaces of the limiting protrusion, when the endoscope tube just enters the positioning threaded tube, the endoscope tube can continuously squeeze the limiting protrusion along the second inclined surface, so that when the endoscope tube can smoothly enter the positioning threaded tube, the smooth operation of the endoscope tube is ensured and avoided jamming.

[0026] (3) The present invention can not only press the endoscope tube to effectively limit the endoscope tube through the structural design of the elastic mechanism, but also quickly adjust the elastic force of each elastic mechanism according to the actual operation angle, so that the endoscope tube is kept in the middle as much as possible, thereby improving the detection accuracy; specifically, through the elastic force of the pressing spring, multiple adjustment blocks are effectively pressed and limited to the endoscope tube. At the same time, during the actual detection process, due to the different lying angles of the patient and the actual operation angle, the endoscope tube cannot be in the middle position, resulting in deviation. At this time, the operator can rotate the corresponding adjustment screw in a targeted manner according to the actual deviation direction. Since the rotating disk at the end of the adjusting screw is rotatably connected to the T-slot, the pressing spring does not affect the rotation of the adjusting screw. In addition, during the rotation process, the relative position of the adjusting screw and the threaded hole changes continuously, thereby causing the adjusting screw to change the length of the pressing spring, thereby comprehensively and quickly adjusting the elastic force of each elastic mechanism, so that the endoscope tube is kept in the middle as much as possible, thereby improving the detection accuracy.

[0027] (4) The present invention can effectively fix the cover plate and achieve a suitable tightening scale through the cooperation of the cover plate and the elastic band, and can also quickly disassemble the elastic band without taking it off the head, thereby improving the patient's comfort and allowing the elastic band to be reused; specifically, when the cover plate needs to be fixed to the patient's head, the oral tube is first inserted into the oral cavity, and then one end of the elastic band with the clamping plate is passed through one of the slots, and after passing through, the clamping plate is laid flat and abutted against the cover plate; the elastic band with the triangular clamping block is passed around the head and passed through the other slot and tightened, at this time, one end of the elastic band with the triangular clamping block and the triangular clamping block are passed out of the other slot together; at this time, since the roller is in active abutment with the side wall of the elastic band, the friction force will drive the roller to rotate during the insertion of the elastic band, causing the two abutment plates to open, thereby preventing the abutment plates from obstructing the elastic band At this time, pull one end of the elastic strap with the triangular clamping block again, and the elastic strap will drive the roller to rotate when moving to open the two abutment plates, thereby realizing rapid recovery of the elastic strap, making the elastic strap reuseable, and also preventing saliva and foreign matter produced by the oral tube from dripping onto the patient's face.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0040] Although the steps in the present invention are arranged with numbers, they are not intended to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0041] Example

[0042] like Figures 1 to 9 As shown, a digestive endoscopy auxiliary device includes a cover plate 100. The cover plate 100 has an opening in the middle, and an oral tube 900 and a positioning threaded tube 400 are fixedly connected at both ends of the opening. An endoscope tube 200 is inserted into both the oral tube 900 and the positioning threaded tube 400. An elastic band 300 is installed at both ends of the cover plate 100.

[0043] The positioning threaded tube 400 has a plurality of adjustment slots 410 uniformly formed around its wall. A rotating rod 420 is fixedly mounted in the middle of each adjustment slot 410. An adjustment block 500 is rotatably connected to the rotating rod 420. A threaded ring 600 is screwed onto the positioning threaded tube 400. A support ring 700 is fixedly mounted on the periphery of the positioning threaded tube 400, located on one side of the threaded ring 600 and away from the cover plate 100. The support ring 700 is connected to one end of the adjustment block 500 via an elastic mechanism 800.

[0044] When the threaded ring 600 is located outside the rotating rod 420, the adjustment block 500 and one end close to the support ring 700 press against the endoscope tube 200; when the threaded ring 600 is located outside the adjustment block 500 and one end away from the support ring 700, the adjustment block 500 and one end away from the support ring 700 press against the endoscope tube 200.

[0045] The present invention cooperates with the positioning threaded tube 400, the adjustment block 500, the elastic mechanism 800, and the threaded ring 600 to not only keep the endoscope tube 200 in the middle as much as possible when the endoscope tube 200 is moved for detection, but also improves the detection accuracy without hindering the movement of the endoscope tube 200. At the same time, it can also quickly adjust the endoscope tube 200 when it is necessary to temporarily stop the detection. The endoscope tube 200 can be quickly limited and fixed with one hand, so that the endoscope tube 200 is quickly fixed in the middle position, thereby avoiding the endoscope tube 200 from twisting and further improving the detection accuracy. Specifically, when it is necessary to move the detection, the endoscope tube 200 is inserted into the positioning threaded tube 400. Under the joint action of multiple elastic mechanisms 800, the adjustment block 500 and one end close to the support ring 700 press the endoscope tube 200, thereby effectively limiting the endoscope tube 200 and making the endoscope tube 200 00 is kept in the middle position as much as possible, thereby making the visual detection image of the endoscope tube 200 more referenceable, improving the detection accuracy of the endoscope tube 200, and at the same time, since the elastic mechanism 800 is elastically abutted, it will not hinder the movement of the endoscope tube 200, thereby improving the smoothness of the movement of the endoscope tube 200; at the same time, when the endoscope tube 200 needs to be temporarily fixed for detection, it is only necessary to rotate the positioning threaded tube 400 with one hand, so that the positioning threaded tube 400 continuously presses down one end of the adjustment block 500, and finally makes the adjustment block 500 and the end away from the support ring 700 press against the fixed endoscope tube 200 for temporary fixation, so that the one-handed operation can quickly limit and fix it, so that the endoscope tube 200 is quickly fixed in the middle position, thereby avoiding the endoscope tube 200 from twisting, thereby facilitating the visual image detection and sampling work of fixed angles, reducing human detection errors, and further improving detection accuracy.

[0046] Furthermore, the adjustment block 500 includes a positioning protrusion 510, a rotating block 520 and a limiting protrusion 530 that are connected to each other in sequence; the protruding direction of the positioning protrusion 510 is toward the outside of the positioning threaded tube 400, and the protruding direction of the limiting protrusion 530 is toward the inside of the positioning threaded tube 400; a rotating hole 521 is opened on the rotating block 520, and the rotating hole 521 is rotatably connected to the corresponding rotating rod 420.

[0047] Furthermore, the protruding direction of the positioning protrusion 510 has a first inclined surface 512, and the first inclined surface 512 is inclined toward the outside of the end of the positioning threaded tube 400 close to the cover plate 100; the protruding direction of the limiting protrusion 530 has two second inclined surfaces 532, and the two second inclined surfaces 532 form a protrusion.

[0048] The present invention can realize two kinds of quick adjustment, namely mobile detection and temporary fixation, by the structural design of the adjustment block 500, while ensuring the smooth operation of the endoscope tube 200 and avoiding jamming. Specifically, when mobile detection is required, the threaded ring 600 is placed on the outside of the rotating rod 420. At this time, the threaded ring 600 is in the middle area and does not exert force on the adjustment block 500. Therefore, the adjustment block 500 is only subjected to the force of the elastic mechanism 800, and only the limiting protrusion 530 limits the movability of the endoscope tube 200. At this time, the endoscope tube 200 can be moved for mobile detection. When temporary fixation is required, the threaded ring 600 is rotated with one hand so that the threaded ring 600 continuously squeezes the first inclined surface 51 2. Finally, the multiple positioning protrusions 510 limit and fix the endoscope tube 200. At this time, due to the rotation connection between the rotating hole 521 and the corresponding rotating rod 420, the limiting protrusion 530 will reversely release the limiting effect of the endoscope tube 200, thereby realizing two rapid adjustment modes of mobile detection and temporary fixation; at the same time, through the structural design of the two second inclined surfaces 532 of the limiting protrusion 530, when the endoscope tube 200 just enters the positioning threaded tube 400, the endoscope tube 200 can continuously squeeze the limiting protrusion 530 along the second inclined surfaces 532, so that when the endoscope tube 200 can smoothly enter the positioning threaded tube 400, the operation smoothness of the endoscope tube 200 is ensured to avoid jamming.

[0049] Furthermore, avoidance grooves 522 are provided on the outer sides of the connection points between the rotating block 520 and the positioning protrusion 510 and the limiting protrusion 530 .

[0050] Through the structural design of the avoidance groove 522, the rotating block 520 can fully avoid the threaded ring 600 during the rotation process, and the problem of jamming will not occur. Further, the operation of the endoscope tube 200 entering the positioning threaded tube 400 is smooth and jamming is avoided.

[0051] Furthermore, a first pressing surface 531 is formed at the connection between the two second inclined surfaces 532 ; and a second pressing surface 511 is formed at the inner end of one end of the positioning protrusion 510 close to the cover plate 100 .

[0052] Due to the structural design of the first pressing surface 531 and the second pressing surface 511 , the rotating block 520 can press the endoscope tube 200 smoothly, thereby preventing damage to the endoscope tube 200 .

[0053] Furthermore, a plurality of fixing rods 710 are evenly fixed on the inner side of the support ring 700 , and the fixing rods 710 are fixedly connected to the outer wall of the positioning threaded tube 400 ; the fixing rods 710 and the adjustment slots 410 are alternately arranged.

[0054] Furthermore, the elastic mechanism 800 includes a pressure spring 810, one end of which is fixedly connected to the adjustment block 500, and the other end of which is fixedly connected to a T-shaped slot 820. The T-shaped slot 820 is provided with an adjusting screw 830, and one end of the adjusting screw 830 is fixedly connected to a rotating disk 831. The rotating disk 831 is located inside the T-shaped slot 820 and is rotatably connected to the T-shaped slot 820.

[0055] The support ring 700 is evenly provided with a plurality of threaded holes 720 , and the threaded holes 720 are threadedly connected to corresponding adjusting screws 830 .

[0056] The present invention adopts the structural design of the elastic mechanism 800, which can not only flexibly press the endoscope tube 200 to effectively limit the pressing endoscope tube 200, but also quickly adjust the elastic force of each elastic mechanism 800 according to the actual operation angle, so that the endoscope tube 200 can be kept in the middle as much as possible, thereby improving the detection accuracy; specifically, through the elastic force of the pressing spring 810, the multiple adjustment blocks 500 can effectively press the limiting endoscope tube 200. At the same time, during the actual detection process, due to the different lying angles of the patient and the actual operation angle, the endoscope tube 200 cannot be in the middle position, resulting in Deviation. At this time, the operator can rotate the corresponding adjusting screw 830 in a targeted manner according to the actual deviation direction. Since the rotating disk 831 at the end of the adjusting screw 830 is rotatably connected to the T-slot 820, the pressure spring 810 does not affect the rotation of the adjusting screw 830, and during the rotation process, the relative position of the adjusting screw 830 and the threaded hole 720 is constantly changing, thereby causing the adjusting screw 830 to change the length of the pressure spring 810, thereby comprehensively and quickly adjusting the elastic force of each elastic mechanism 800, so that the endoscope tube 200 is kept in the middle as much as possible, thereby improving the detection accuracy.

[0057] Furthermore, one end of the elastic band 300 is fixedly connected to a clamping plate 310 , and a plurality of triangular clamping blocks 320 are evenly arranged on both sides of the side wall of the other end.

[0058] Furthermore, slots 110 are provided at both ends of the cover plate 100, and two rotating slots 120 are symmetrically provided on one of the slots 110 and the slot close to the side of the positioning threaded tube 400. Each rotating slot 120 is rotatably connected to a roller 130 via a rotating shaft, and the side wall of the roller 130 is fixedly connected to an abutment plate 140; the roller 130 is movably abutted against the side wall of the elastic band 300; one end of the elastic band 300 with a triangular clamping block 320 passes through the slot 110 with two rollers 130, and one end of the elastic band 300 with a clamping plate 310 passes through the other slot 110.

[0059] The present invention can quickly and effectively fix the cover plate 100 and achieve a suitable tightening scale through the cooperation of the cover plate 100 and the elastic band 300. At the same time, the elastic band 300 can be quickly disassembled without being removed from the head, thereby improving the patient's comfort and allowing the elastic band 300 to be reused. Specifically, when the cover plate 100 needs to be fixed to the patient's head, the oral tube 900 is first inserted into the oral cavity, and then one end of the elastic band 300 with the clamping plate 310 is passed through one of the slots 110. After passing through, the clamping plate 310 is placed The elastic band 300 with the triangular block 320 is passed around the head and passed through the other slot 110 and tightened. At this time, one end of the elastic band 300 with the triangular block 320 and the triangular block 320 pass through the other slot 110 together. At this time, since the roller 130 is in active contact with the side wall of the elastic band 300, the friction force will drive the roller 130 to rotate during the insertion of the elastic band 300, so that the two abutment plates 140 are opened to prevent the abutment plates 140 from obstructing the elastic band. The elastic band 300 is inserted; then, it is tightened and released to a suitable degree, and the elastic band 300 is partially retracted due to the expansion and contraction rebound of the elastic band 300. In this process, the elastic band 300 will also drive the roller 130 to rotate in the opposite direction, thereby automatically resetting the two abutment plates 140, so that the triangular clamping block 320 is clamped with the abutment plate 140, thereby achieving automatic clamping and fixing and achieving a suitable tightening scale; at the same time, after the inspection is completed, the elastic band 300 with the clamping plate 310 is pulled and Adjust the card plate 310 so that the card plate 310 passes back through the corresponding slot 110 and is separated from the cover plate 100 for quick untying, so that it can be quickly disassembled without taking it off the head, thereby improving the patient's comfort; at this time, pull one end of the elastic strap 300 with the triangular card block 320, and the elastic strap 300 will drive the roller 130 to rotate when moving to open the two abutment plates 140, thereby achieving quick recovery of the elastic strap 300, making the elastic strap 300 reusable, and preventing saliva and foreign matter produced by the oral tube 900 from dripping onto the patient's face.

[0060] It is worth noting that the positioning threaded tube 400 of the present invention and the cover plate 100 can also be fixedly connected by threaded connection, so that the positioning threaded tube 400 and related components can be further recycled.

[0061] A method for operating using the above-mentioned digestive endoscopy auxiliary device comprises the following steps:

[0062] S1. First, insert the oral tube 900 into the oral cavity. Then, pass one end of the elastic band 300 with the clamping plate 310 through one of the slots 110. After passing through, lay the clamping plate 310 flat and abut against the cover plate 100. Pass the elastic band 300 with the triangular clamping block 320 around the skull and through the other slot 110. Tighten it. Then, loosen the elastic band 300 so that the triangular clamping block 320 engages with the abutment plate 140.

[0063] S2. Insert the endoscope tube 200 into the positioning threaded tube 400 for inspection. When it is necessary to stop, rotate the threaded ring 600 so that the end of the adjustment block 500 away from the support ring 700 presses against the endoscope tube 200 to achieve temporary fixation.

[0064] S3. After the inspection is completed, pull the elastic band 300 with the card plate 310 and adjust the card plate 310 so that the card plate 310 passes back through the corresponding slot 110 and detaches from the cover plate 100 to achieve quick unbinding. At the same time, pull one end of the elastic band 300 with the triangular card block 320 to achieve quick recovery of the elastic band 300.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several improvements and changes can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
