Description

Technical Field

[0001] The present invention relates to the technical field of colonoscopy, and in particular to a colonoscopy positioning device and a use method thereof. Background Art

[0002] Colonoscopy is a thin and flexible tube inserted through the anus. The front end of the tube is equipped with a video camera. It goes through the rectum to the end of the ileum to examine the interior of the lower digestive tract in detail. However, there are still the following disadvantages in the process of colonoscopy: 1. Due to gas discharge and intestinal peristalsis, a small amount of loose stool or intestinal contents may flow out through the anus. The loose stool or intestinal contents may be ejected under the action of intestinal gas and pollute the medical office; 2. When inserting the colonoscope into the rectum, the doctor needs to manually apply lubricant on the outer wall of the colonoscope, which is time-consuming and labor-intensive, affecting the efficiency of the examination; 3. The colonoscope is inserted into the rectum for examination. Since it is impossible to position the colonoscope, the shaking of the colonoscope may cause changes in the intestine and may cause damage to the patient's anus.

When in use, the patient lies on the device with his legs bent, places the collection frame in the placement slot, and assembles the slide bar, bed board, and U-shaped baffle. The U-shaped baffle is raised and lowered by adjusting the screw to ensure that the sheath is aligned with the patient's anus. The U-shaped baffle can block excrement, while the collection frame and the first fixed rod are responsible for collection to keep the bed board clean. After the examination, the various parts are disassembled for cleaning. At the same time, when the colonoscope is pulled out, the cotton ring can scrape the residue on the outer wall and collect it in the collection box.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1: Reference Figure 1-Figure 3 , a positioning device, relates to the technical field of colonoscopy equipment, the device mainly includes a bed board 1, and a placement slot 2 is arranged on the top of the bed board 1. In the placement slot 2, we placed a collection frame 3, and the collection frame 3 is used to receive waste that may be generated during the inspection process. Inside the collection frame 3, we further placed a frame body 4, and a plurality of first fixing rods 7 are fixed inside the frame body 4. These first fixing rods 7 work together with the collection frame 3 to support the patient's buttocks and ensure that loose stools and intestinal contents can be effectively collected during the inspection.

[0021] Reference Figure 4 and Figure 5In order to block the loose stool ejected from the anus, we set a U-shaped baffle 13 above the first fixed rod 7. A sheath 17 is slidably penetrated through the U-shaped baffle 13 through a slide groove and a slider. The outer wall of the sheath 17 is rotatably sleeved with a conical insert ring 18, which is located on one side of the U-shaped baffle 13 and is used to assist insertion into the patient's anus. At the end of the sheath 17 away from the conical insert ring 18, we set a cotton ring 37, which can rotate and is used to apply lubricant to the colonoscope to be inserted.

[0022] Reference Figure 4 and Figure 5 At the same time, we also fixed a storage tube 14 through the U-shaped baffle 13. This storage tube 14 is located above the sheath 17 and is used to drip lubricant onto the conical insert ring 18 and the cotton ring 37. In this way, it is convenient to insert the conical insert ring 18 into the anus, and the lubricant can be soaked in the sheath 17 to assist the insertion of the colonoscope. In addition, we also fixed a collection box 23 on one side of the U-shaped baffle 13 to collect waste or excess lubricant that may be generated during the inspection.

[0023] Reference Figure 4-Figure 6 In order to drive the sheath 17 and the conical insert ring 18 to move and insert into the patient's anus, we designed an insertion structure. This structure includes a first gear 19 and a rotating rod 22 that rotate on the side of the U-shaped baffle 13 away from the conical insert ring 18. A second gear 21 that meshes with the first gear 19 is fixedly sleeved on the outer wall of the rotating rod 22. A threaded section 20 is provided on the outer wall of the sheath 17, and the first gear 19 is threadedly connected to the sheath 17 through this threaded section 20. Therefore, when the rotating rod 22 is rotated, it drives the second gear 21 to rotate, and then drives the first gear 19 to rotate. Since the first gear 19 is threadedly connected to the threaded section 20 of the sheath 17, the sheath 17 and the conical insert ring 18 will be driven to move toward the patient's anus.

[0024] Specifically, during the movement, we can open the valve on the first liquid outlet pipe 15, so that the lubricant in the storage tube 14 drips onto the conical insert ring 18 through the first liquid outlet pipe 15. In this way, when the sheath 17 drives the conical insert ring 18 to be inserted into the patient's anus, the conical insert ring 18 and the lubricant thereon can reduce the damage caused by the opening of the anus.

[0025] Reference Figure 5-Figure 8In order to ensure that the colonoscope remains stable during insertion, we designed a clamping structure. This structure includes a worm 26 that rotates on the top of the sheath 17 through a base. The outer wall of the worm 26 is fixedly sleeved with two second rotating wheels 25, and the bottoms of the two second rotating wheels 25 extend into the sheath 17. At the bottom of the sheath 17, we connected a hollow shaft 30 through the base rotation. The outer wall of the hollow shaft 30 is fixedly sleeved with a first rotating wheel 24, and the outer wall of the first rotating wheel 24 is fixedly sleeved with two annular airbags 32. The tops of the two annular airbags 32 extend into the sheath 17. When the annular airbags 32 are inflated, they will cooperate with the second rotating wheel 25 to clamp the colonoscope. In order to achieve the inflation of the annular airbags 32, we set two air guide holes 33 between the first rotating wheel 24 and the hollow shaft 30, and the two annular airbags 32 are connected to the hollow shaft 30 through the two air guide holes 33 respectively. One end of the hollow shaft 30 rotates and passes through a gas injection pipe 31 . The gas injection pipe 31 is connected to an external air pump through a hose and is used to inject gas into the annular air bag 32 .

[0026] When in use, one end of the enteroscope is inserted into the sheath 17 through a circular ring 36. Then, an external air pump cooperates with the air injection tube 31 to inject gas into the hollow shaft 30. The gas enters the annular airbag 32 through the air guide hole 33, causing the annular airbag 32 to expand and cooperate with the second rotating wheel 25, thereby preliminarily completing the fixation of the enteroscope.

[0027] Reference Figure 6 , Figure 7 and Fig. 9 In addition, we also set a coating structure on the sheath 17 to drive the cotton ring 37 to rotate and apply the lubricant to the outer wall of the colonoscope. The specific setting method of the coating structure is as follows: a transmission rod 27 is connected to the top of the sheath 17 through a base, and the transmission rod 27 is located below the worm 26 and between the two second rotating wheels 25. A worm wheel 28 is fixedly sleeved on the outer wall of the transmission rod 27, and the worm wheel 28 is meshed with the worm 26. Therefore, when the worm 26 rotates, the transmission rod 27 is driven to rotate through the worm wheel 28.

[0028] Reference Figure 6 and Fig. 9A third gear 29 is fixed to one end of the transmission rod 27 close to the cotton ring 37. A rotating gear ring 34 is rotatably connected to one end of the sleeve 17 away from the conical insert ring 18, and the rotating gear ring 34 is meshed with the third gear 29. Therefore, when the transmission rod 27 rotates, the third gear 29 is driven to rotate, and then the rotating gear ring 34 is driven to rotate through the meshing of the third gear 29 and the rotating gear ring 34. A plurality of guide rods 35 are fixed to one side of the rotating gear ring 34, and the same circular ring 36 is fixed to one end of the plurality of guide rods 35. The cotton ring 37 is detachably fixed in the circular ring 36. Therefore, when the rotating gear ring 34 rotates, the circular ring 36 is driven to rotate through the guide rods 35, and then the cotton ring 37 rotates accordingly.

[0029] Reference Fig. 9 , an annular groove 44 is provided on the outer wall of the ring 36, and a plurality of through holes 38 connected to the annular groove 44 are provided in the ring 36. The first liquid outlet pipe 15 and the second liquid outlet pipe 16 are fixedly connected to the two sides of the bottom of the storage cylinder 14, and the first liquid outlet pipe 15 and the second liquid outlet pipe 16 are respectively located on the two sides of the U-shaped baffle 13. The first liquid outlet pipe 15 is used to drip lubricant to the outer wall of the conical insert ring 18, and the second liquid outlet pipe 16 is used to drip lubricant into the annular groove 44. Solenoid valves 43 are provided on the outer walls of the first liquid outlet pipe 15 and the second liquid outlet pipe 16 to control the outflow of lubricant.

[0030] When in use, first open the solenoid valve 43 on the first liquid outlet pipe 15, and the lubricant in the storage tube 14 drips onto the conical plug ring 18 through the first liquid outlet pipe 15. Then, the sheath 17 drives the conical plug ring 18 to be inserted into the patient's anus, and the conical plug ring 18 and the lubricant thereon can reduce the damage when the anus is opened. Next, close the solenoid valve 43 on the first liquid outlet pipe 15, open the solenoid valve 43 on the second liquid outlet pipe 16, and the lubricant in the storage tube 14 slowly flows into the annular groove 44 through the second liquid outlet pipe 16. At this time, rotate the worm 26, the worm 26 drives the second rotating wheel 25 to rotate, and the second rotating wheel 25 cooperates with the first rotating wheel 24 and the annular airbag 32 to drive the colonoscope to be inserted into the patient's rectum. At the same time, the worm 26 also drives the transmission rod 27 and the third gear 29 to rotate through the worm wheel 28, and the third gear 29 cooperates with the rotating gear ring 34 to drive the ring 36 to rotate. When the circular ring 36 rotates, the lubricant soaks the cotton ring 37 through the through hole 38, so the rotation of the cotton ring 37 can automatically apply the lubricant to the outer wall of the colonoscope without manual application, which greatly improves the application efficiency.

[0031] Reference Figure 3 In addition, multiple card slots 6 are provided on the inner walls of the two sides of the collection frame 3 that are away from each other, and multiple card blocks 5 are fixed on both sides of the frame 4, and the card blocks 5 slide in cooperation with the card slots 6. When the frame 4 needs to be installed on the collection frame 3, it is only necessary to align the card blocks 5 with the card slots 6 and slide and insert them, so as to realize the positioning of the frame 4 and facilitate disassembly and installation.

[0032] Reference Figure 2 and Figure 3 The U-shaped baffle 13 in the present device is designed with an internal thread, which is used to penetrate the screw rod 11. At the same time, the U-shaped baffle 13 is also provided with a sliding hole, which is used to slide through the slide rod 9. The bottom end of the screw rod 11 is rotatably connected to the second fixed rod 10, so that the screw rod 11 can drive the second fixed rod 10 to move up and down when it rotates. Two slots 8 are provided on the bottom inner wall of the collection frame 3, and the two slots 8 are respectively plugged into and matched with the bottom ends of the second fixed rod 10 and the slide rod 9. When the height of the U-shaped baffle 13 needs to be adjusted, it can be achieved by rotating the screw rod 11. Since the U-shaped baffle 13 is made of transparent acrylic material, the situation below the U-shaped baffle 13 can be clearly observed, which is convenient for positioning during colonoscopy.

[0033] Reference Figure 3 The outer walls of the second fixing rod 10 and the sliding rod 9 are both fixedly sleeved with a gasket 12. When the second fixing rod 10 and the sliding rod 9 are respectively inserted into the slot 8, the gasket 12 can fit tightly against the opening of the slot 8, playing the role of closing the slot 8 and preventing liquid or dirt from seeping out of the slot 8.

[0034] Through the above settings, we can achieve stable insertion of the colonoscope and effectively collect waste generated during the examination. The device can also automatically apply lubricant to the outer wall of the colonoscope to reduce damage when the anus is opened, and facilitate disassembly and installation, thereby improving the efficiency and comfort of colonoscopy.

[0035] Example 2: Reference Fig.10 , improved on the basis of Example 1: a mounting plate 39 is fixed to one side of the collection frame 3. A plurality of threaded holes 40 and a screw rod 41 matched with the threaded holes 40 are provided in the mounting plate 39. A pad 42 is rotatably connected to the top of the screw rod 41. When using this device, the patient lies on his side on the bed board 1. In order to increase the patient's comfort and facilitate his side lying, the pad 42 can be rotated so that its protrusion extends in the direction of the patient. In this way, one leg of the patient can be placed on the pad 42 to maintain a comfortable side-lying posture. By adjusting the position of the screw rod 41 in the threaded hole 40, the height and angle of the pad 42 can be further adjusted to meet the needs of different patients.

[0036] A method for using a colonoscopy positioning device comprises the following steps: S1. When in use, the collection frame 3 is placed in the placement slot 2, and the patient lies on the first fixed rod 7 and the frame 4 with legs bent. Then, the slide bar 9 and the bed board 1 are inserted into the corresponding two slots 8 to complete the placement of the U-shaped baffle 13. Then, the U-shaped baffle 13 is controlled to rise and fall by rotating the screw 11 until the sheath 17 is aligned with the patient's anus. When the patient's anus sprays loose stools and intestinal contents, the U-shaped baffle 13 can block them, and the cooperation between the collection frame 3 and the first fixed rod 7 can block the loose stools and intestinal contents. The stool and intestinal contents are collected to avoid contamination of the bed board 1, which is convenient for the cleaning of the bed board 1 in the later stage. In addition, after the colonoscopy is completed, the collection frame 3 is taken out from the placement slot 2, and the frame body 4, the U-shaped baffle 13, the second fixing rod 10, the sliding rod 9 and the collection frame 3 are removed respectively, which is convenient for the later cleaning. In addition, when the colonoscope is pulled out of the circular ring 36 and the cotton ring 37, the cotton ring 37 can scrape the loose stool and intestinal contents on the outer wall of the colonoscope, and the collection box 23 can just collect these loose stool and intestinal contents; S2, the second gear 21 is driven to rotate by the rotating rod 22, and the second gear 21 drives the first gear 19 to rotate. The first gear 19 is threadedly connected with the sheath 17 through the threaded section 20, driving the sheath 17 and the tapered insert ring 18 to move toward the patient's anus. When moving, the valve on the first liquid outlet pipe 15 is opened, and the lubricant in the storage cylinder 14 drips onto the tapered insert ring 18 through the first liquid outlet pipe 15. When the sheath 17 drives the tapered insert ring 18 to be inserted into the patient's anus, the tapered insert ring 18 and the lubricant thereon can reduce the damage to the anus when it is opened, and at this time, the ring 36 is just located below the second liquid outlet pipe 16; S3. When the enteroscope needs to be inserted, one end of the enteroscope is inserted into the sheath 17 through the circular ring 36, and then the air pump on the outer wall cooperates with the air injection tube 31 to inject air into the hollow shaft 30, and the air enters the annular airbag 32 through the air guide hole 33, and the annular airbag 32 expands and cooperates with the second rotating wheel 25, thereby preliminarily completing the fixation of the enteroscope; S4. The second rotating wheel 25 is driven to rotate by the worm 26. The second rotating wheel 25 cooperates with the first rotating wheel 24 and the annular airbag 32 to drive the colonoscope to be inserted into the patient's rectum. The worm 26 drives the transmission rod 27 and the third gear 29 to rotate through the worm wheel 28. The third gear 29 cooperates with the rotating gear ring 34 to drive the circular ring 36 to rotate. The lubricant in the storage cylinder 14 slowly flows into the annular groove 44 through the second liquid outlet pipe 16. When the circular ring 36 rotates, the lubricant soaks the cotton ring 37 through the through hole 38. Therefore, the rotation of the cotton ring 37 can automatically apply the lubricant to the outer wall of the colonoscope without manual application, thereby greatly improving the application efficiency.
