Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an anus expansion device for colonoscopy. BACKGROUND

[0002] Anus expansion for colonoscopy in the department of gastroenterology is a common medical examination method used to assess the health of the rectal and anal regions. This examination is usually performed by a gastroenterologist or a gastrointestinal specialist, aiming to detect and diagnose various digestive system problems such as tumors, polyps, inflammation, ulcers, etc. Through colonoscopy, doctors can directly observe the internal situation of the anus and rectum to discover and treat potential diseases in a timely manner.

[0003] In the prior art, an expansion device is needed when performing anus expansion for colonoscopy in the department of gastroenterology. However, the traditional expansion device has a single function, and it needs to be coated with lubricating oil before use. However, after insertion, the lubricating oil does not have much lubrication due to the close contact of the skin, causing increased pain. Moreover, most expansion adjustment methods can only achieve expansion in the up-down or left-right direction, and cannot achieve overall expansion in four directions, resulting in low detection efficiency and inconvenience in use.

[0004] When applying the present application, the applicant found that a "anus expansion device for colonoscopy in the department of gastroenterology" has been disclosed in a Chinese patent with the application number "202421215182.X". This patent mainly achieves the expansion of the patient's anus by controlling the opening and closing of the inserted petals through a control button, without the need for manual adjustment of the mechanical structure, thereby reducing the workload of the doctor and improving the convenience of use. However, the lubricating liquid is still reserved on the outside after the expansion device is inserted into the anus, resulting in poor internal lubrication. Therefore, according to the applicant's invention, an anus expansion device for colonoscopy is invented to solve the problem of the single function of traditional expansion devices, which requires the use of lubricating oil before use. However, after insertion, the lubricating oil does not have much lubrication due to the close contact of the skin, causing increased pain. SUMMARY

[0005] Technical problems solved To overcome the shortcomings of the prior art, the present application provides an anus expansion device for colonoscopy, which solves the problem of the single function of traditional expansion devices, which requires the use of lubricating oil before use. However, after insertion, the lubricating oil does not have much lubrication due to the close contact of the skin, causing increased pain.

[0006] Technical solution In order to achieve the above object, the present application is realized by the following technical scheme: An anus dilating device for enteroscopy detection, comprising: a dilating hard tube, one end of the dilating hard tube is fixedly connected with a convex block, one side of the convex block is fixedly connected with a moving rod, the outside of the moving rod is sleeved with a fixed ring, one end of the moving rod away from the convex block is fixedly connected with a connecting plate, the outside of the connecting plate is fixedly connected with a concave tube, an internal thread is formed in the inside of the concave tube, a bidirectional screw rod is screwed in the internal thread of the concave tube, the middle part of the bidirectional screw rod is fixedly connected with a knob, liquid inlet holes are formed in the two ends of one side of the convex block, a connecting pipe is inserted into the liquid inlet holes, a flow-through branch pipe is fixedly connected to one side of the middle part of the connecting pipe, and a piston sleeve is fixedly connected to one end of the flow-through branch pipe.

[0007] As a preferred technical scheme of the present application: the upper side of the fixed ring is fixedly connected with a plurality of supporting springs, the top end of the supporting spring is fixedly connected with a buffer pad, and the buffer pad is made of flexible material.

[0008] As a preferred technical scheme of the present application: a plurality of liquid discharge holes are formed on the outer surface of the dilating hard tube.

[0009] As a preferred technical scheme of the present application: the two sides of the fixed ring are fixedly connected with elastic bands, one end of the elastic band away from the fixed ring is fixedly connected with a forward hook, and the other end of the elastic band away from the fixed ring is fixedly connected with a reverse hook, and the forward hook and the reverse hook are hung in cooperation.

[0010] As a preferred technical scheme of the present application: a piston rod is inserted into the inside of the piston sleeve.

[0011] As a preferred technical scheme of the present application: the end of the dilating hard tube is arranged in an arc shape and inclined to the middle part.

[0012] As a preferred technical scheme of the present application: the inside of the dilating hard tube is in a hollow shape, and the concave tube is in a concave shape.

[0013] A use method of an anus dilating device for enteroscopy detection, comprising the following specific use steps: Step one: when in use, first rotate the knob in reverse direction, screw the bidirectional screw rod outside with the inner wall of the concave tube, screw the two ends of the bidirectional screw rod with the concave tube to the middle part, so that the inside of the concave tube moves the moving rod and the convex block to the middle part, and the dilating hard tube is in a sharp cone shape at this time, and the operation resets the overall structure; Step 2: Next, wrap the elastic bands on both sides of the outer side of the fixing ring around the patient's buttocks and front side, and hook them onto the front and back hooks under the patient's abdomen. During the wrapping process, the elastic bands are stretched, and at this time, the entire structure of the fixing ring can be fixed to the patient's buttocks. At the same time, the arc-shaped cone end of the dilator tube will be inserted into the patient's anus. Step 3: During the insertion of the dilator tube into the patient's anus, medical staff need to connect it through the connecting tube and the inlet hole. Then, the lubricating fluid inside the piston sleeve is injected, and the piston rod is pushed to one side of the dilator tube. At this time, the lubricating fluid will flow through the circulation branch tube to the connecting tube and then through the inlet hole into the interior of the dilator tube. Since there are several drainage holes on the surface of the dilator tube, the lubricating fluid can be discharged to the outside, which increases the lubrication effect while the dilator tube is inserted into the anus. Step 4: After inserting the dilator tube into the anus, the elastic band can be kept in place by elastic stretching, and it is not easy to shift or fall off. Then the cushioning pad contacts the patient's buttocks, and the support spring increases elastic cushioning and increases comfort. Step 5: When expansion is needed, the knob can be turned forward to drive the bidirectional screw to rotate, which engages with the threaded inner wall of the concave tube to achieve threaded movement, moving the concave tube outward. During the movement, it can drive the expansion operation of the moving rod and the convex block as a whole structure. This adjustment can achieve horizontal expansion by turning one knob, while vertical expansion is required by turning the other knob. Thus, by setting two knobs, the two concave tubes can be expanded vertically and horizontally, which facilitates medical staff to accurately diagnose and treat the internal condition of the anus.

[0014] Beneficial effects This invention provides an anal dilation device for colonoscopy. It has the following beneficial effects: This invention comprises a knob, a bidirectional screw, a concave tube, a moving rod, and a convex block. Rotating the knob forward causes the bidirectional screw to rotate threadedly, engaging with the threaded inner wall of the concave tube to achieve threaded movement. This allows the concave tube to move outward, and during this movement, it expands the entire structure of the moving rod and the convex block, thereby facilitating accurate diagnosis and treatment of the anal cavity by medical personnel.

[0015] This invention comprises a piston sleeve, a flow branch pipe, a connecting pipe, and a drain hole. Lubricating fluid is injected into the piston sleeve, and the piston rod is pushed towards one side of the dilator tube. The lubricating fluid then flows through the flow branch pipe to the connecting pipe and then through the inlet hole into the interior of the dilator tube. Because the surface of the dilator tube has several drain holes, the lubricating fluid can be discharged outwards, thus increasing lubrication during insertion of the dilator tube into the anus. This structure enhances lubrication, providing lubrication inside the anus and reducing pain caused by dryness and friction.

[0016] This invention features a fixing ring, elastic bands, a forward hook, and a reverse hook. The elastic bands on both sides of the fixing ring are wrapped around the front of the patient's buttocks and hooked onto the forward and reverse hooks below the patient's abdomen. During the wrapping process, the elastic bands are stretched, which helps to fix the entire fixing ring structure to the patient's buttocks, providing stability, preventing it from falling off, and freeing up medical staff from handling it.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: like Figures 1-6 As shown, this embodiment of the invention provides an anal dilation device for colonoscopy, including a dilation tube 1. One end of the dilation tube 1 is fixedly connected to a convex block 601, and a movable rod 6 is fixedly connected to one side of the convex block 601, which moves the concave tube 5 outward. During the movement, it can drive the expansion operation of the movable rod 6 and the convex block 601 as a whole. A fixing ring 4 is sleeved on the outside of the movable rod 6. A connecting plate 503 is fixedly connected to the end of the movable rod 6 away from the convex block 601, and a concave tube is fixedly connected to the outside of the connecting plate 503. 5. The two knobs 502 allow for vertical and horizontal expansion of the two concave tubes 5, facilitating precise diagnosis and treatment by medical personnel. The concave tubes 5 have internal threads at their center, connected to a bidirectional screw 501. Both ends of the bidirectional screw 501 are positioned closer to the center, thus placing the inner moving rod 6 and the convex block 601 of the concave tubes 5 in the centered position. At this point, the expansion tube 1 takes on a conical shape. This operation further enhances the overall structure... A knob 502 is fixedly connected to the middle of the bidirectional screw 501. By rotating the knob 502 in the reverse direction, the outer side of the bidirectional screw 501 engages with the inner wall of the concave tube 5, causing both ends of the concave tube 5 to move closer to the center. Conversely, rotating the knob 502 in the forward direction will drive the bidirectional screw 501 to rotate threadedly, engaging with the inner wall of the concave tube 5, thus achieving threaded movement and moving the concave tube 5 outward. Liquid inlet holes 102 are provided at both ends of one side of the convex block 601. The internal part of tube 2 is connected to a connecting tube 702. When the dilating tube 1 is inserted into the patient's anus, medical staff need to connect it through the connecting tube 702 and the inlet hole 102. A flow branch tube 701 is fixedly connected to the middle of one side of the connecting tube 702. A piston sleeve 7 is fixedly connected to one end of the flow branch tube 701. Lubricating fluid is injected into the piston sleeve 7, and the piston rod 703 is pushed to one side of the dilating tube 1. At this time, the lubricating fluid will flow through the flow branch tube 701 to the connecting tube 702 and then through the inlet hole 102 to the inside of the dilating tube 1.

[0021] In a preferred embodiment: a plurality of support springs 201 are fixedly connected to the top of the fixing ring 4, and a buffer pad 2 is fixedly connected to the top of the support springs 201. The buffer pad 2 contacts the patient's buttocks. The support springs 201 increase elastic cushioning and increase comfort. The buffer pad 2 is made of flexible material.

[0022] In a preferred embodiment, the outer surface of the dilator tube 1 is provided with a plurality of drainage holes 101. Since the surface of the dilator tube 1 is provided with a plurality of drainage holes 101, the lubricant can be discharged to the outside, thereby increasing the lubrication effect when the dilator tube 1 is inserted into the anus.

[0023] In a preferred embodiment: elastic bands 3 are fixedly connected to both sides of the fixing ring 4. The elastic bands 3 on both sides of the outer side of the fixing ring 4 are wrapped around the patient's buttocks and forward side. One end of the elastic band 3 away from the fixing ring 4 is fixedly connected to a forward hook 301, and the other end of the elastic band 3 away from the fixing ring 4 is fixedly connected to a reverse hook 302. The forward hook 301 and the reverse hook 302 are hooked together and hooked through the lower abdomen of the patient. During the wrapping process, the elastic band 3 is in a stretched state, and at this time, the entire structure of the fixing ring 4 can be fixed to the patient's buttocks.

[0024] In a preferred embodiment, a piston rod 703 is inserted into the inside of the piston sleeve 7.

[0025] In a preferred embodiment, the end of the expansion tube 1 is arc-shaped and inclined towards the center.

[0026] In a preferred embodiment: the interior of the expansion tube 1 is hollow, and the concave tube 5 is concave.

[0027] Example 2: The difference between this embodiment and Embodiment 1 is that: a method of using an anal dilation device for colonoscopy includes the following specific steps: Step 1: When using it, first turn the knob 502 in the opposite direction to make the outside of the double-ended screw 501 threaded with the inner wall of the concave tube 5. This will bring both ends of the concave tube 5 of the double-ended screw 501 closer to the middle, so that the inner moving rod 6 and the convex block 601 of the concave tube 5 are in the middle state. At this time, the expansion hard tube 1 is in the shape of a pointed cone. This operation resets the overall structure. Step 2: Then, wrap the elastic bands 3 on both sides of the outer side of the fixing ring 4 around the front of the patient's buttocks, and hook them onto the forward hook 301 and reverse hook 302 under the patient's abdomen. During the wrapping process, the elastic bands 3 are in a stretched state. At this time, the entire structure of the fixing ring 4 can be fixed to the patient's buttocks. At the same time, one end of the dilator tube 1 with an arc-shaped cone will be inserted into the patient's anus. Step 3: During the insertion of the dilating tube 1 into the patient's anus, medical staff need to connect it through the connecting tube 702 and the inlet hole 102. Then, the internal lubricant of the piston sleeve 7 is injected, and the piston rod 703 is pushed to one side of the dilating tube 1. At this time, the lubricant will flow through the flow branch tube 701 to the connecting tube 702 and then through the inlet hole 102 to the inside of the dilating tube 1. Since the surface of the dilating tube 1 has several drainage holes 101, the lubricant can be discharged to the outside, which increases the lubrication effect when the dilating tube 1 is inserted into the anus. Step 4: After inserting the dilator tube 1 into the anus, the elastic band 3 can be kept fixed by elastic stretching, and it is not easy to shift the position or fall off. Then the cushioning pad 2 contacts the patient's buttocks, and the support spring 201 increases elastic cushioning and increases comfort. Step 5: When expansion is needed, the knob 502 can be rotated forward, which will drive the bidirectional screw 501 to rotate threadedly. This screw engages with the threaded inner wall of the concave tube 5, allowing for threaded movement and outward movement of the concave tube 5. During this movement, the moving rod 6 and the convex block 601 can be expanded as a whole. Rotating one knob 502 can achieve horizontal expansion on both sides, while rotating the other knob 502 is required for vertical expansion. Thus, by using the two knobs 502, vertical and horizontal expansion of the two concave tubes 5 can be achieved, facilitating accurate diagnosis and treatment of the anal cavity by medical personnel.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
