[0002] With the continuous development of society, living conditions are getting better and better, the variety of food available is gradually increasing, and more and more emerging industries are emerging. Most workers need to be sedentary for a long time. Various reasons lead to the onset of anorectal diseases. Anorectal diseases are common diseases at present. Doctors need to understand the patient's diseased parts, so anal dilation is one of the necessary steps when examining anorectal diseases. Doctors usually need to open the anus with dilator forceps before observation to facilitate observation of the inside of the patient's diseased part.
[0003] However, the expansion forceps currently used in the observation process require the doctor to adjust the expansion width and then fix it by adjusting the bolts under the expansion part. In addition, light is not easy to enter the anus and rectum, and an assistant is required to use a flashlight to illuminate the anus and rectum, which increases the cumbersomeness of the observation process. If the expansion width needs to be adjusted again during the observation process, the bolts need to be readjusted to fix it, which has poor flexibility. Utility Model Content
[0004] The utility model aims to provide an anal dilation device, wherein a slidable sliding component is arranged between grip rods, the sliding component cooperates with a ratchet pawl to dilate and the pawl engages with the ratchet wheel to fix, after the inspection is completed, the handle is pushed upward to cancel the fixation of the pawl and reduce the expansion width, thereby reducing the operation steps during the observation process, improving the flexibility of the adjustment process, and making it convenient for doctors to conduct inspections alone.

The top of the lubricating part is engaged on several protrusions, making it more convenient to replace.
[0013] Furthermore, the top of the expansion plate is semicircular, and the bottom of the expansion plate is arc-shaped. The adjacent two side walls of the expansion plate are wrapped with arc-shaped silicone strips.
[0014] Beneficial effects: The expansion plate is set to be circular as a whole, and the bottom is smooth as a whole, which reduces the discomfort of patients when using it. The silicone strip is set to be arc-shaped, so that the interface of two adjacent expansion plates is smooth when closed, and the overlapping area of the interface is small, which is not easy to pinch the intestinal tissue, avoid causing harm to the patient, improve the comfort of the patient during the examination process, and increase the practicality of the expander.
[0015] Furthermore, the sliding assembly includes a cross bar, and a groove is formed on the outer wall of the cross bar close to the expansion plate. A rack is fixedly connected in the groove, and the rack is engaged with the ratchet.
[0016] Beneficial effect: the rack and the ratchet are slidably matched, so that when the first gripping rod and the second gripping rod are gripped, the ratchet is always ready to fix the expander without the need for further debugging, thereby increasing the flexibility of the operation process.
[0017] Furthermore, the length of the cross bar is greater than the distance between the first grip bar and the second grip bar.
[0018] Beneficial effect: It is conducive to the use of the operation process, so that the rack is always engaged with the ratchet, thereby driving the ratchet to rotate.
[0019] Furthermore, an elastic member is fixedly connected to the top of the pawl, and the other end of the elastic member is fixedly connected to one side of an adjacent sliding block.
[0020] Beneficial effect: The position of the pawl is fixed so that the pawl is still within the rotation track of the ratchet wheel when the connecting rod drives the pawl to move downward.
[0021] Furthermore, one end of the connecting rod away from the sliding block extends to the outside of the second gripping rod, and the extension length is greater than the diameter of the handle.
[0022] Beneficial effect: The contact area between the operator, the handle and the connecting rod is increased, making it easier to push the handle during use, thereby improving the operator's experience when pushing the handle.
[0023] Furthermore, a buckle is fixedly connected to the side wall of the sliding block close to the rack, a through groove for engaging the buckle is opened in the sliding groove, and a silicone layer is fixedly connected to the inner wall of the through groove.
[0024] Beneficial effect: when the connecting rod drives the pawl to escape from the motion track of the ratchet wheel, the position of the connecting rod is stabilized; when the buckle is engaged in the through groove, the silicone layer can increase the friction between the buckle and the through groove, making it difficult for the slider to fall off.

The lubricating member is wrapped around the outer walls of the two expansion plates 2. During inspection, the two expansion plates 2 are spread apart to cause the lubricating member to collapse, squeezing out the lubricating oil therein, making it easier to place the expander into the affected area and reducing the patient's discomfort. The top of the lubricating member is engaged with a number of protrusions 3, making it more convenient to replace.
[0032] The first gripping rod 1 and the second gripping rod 8 are integrally connected to the outer side walls of the two expansion plates 2 close to each other, and the first gripping rod 1 and the second gripping rod 8 are hinged at one end close to the expansion plate 2. A sliding assembly is welded on the inner side wall of the first gripping rod 1, and the sliding assembly includes a cross bar 5. A groove is opened on the outer side wall of the cross bar 5 close to the expansion plate 2, and a rack 6 is welded in the groove. The rack 6 rotates with the driving assembly, so that when the first gripping rod 1 and the second gripping rod 8 are grasped, the cross bar 5 is stretched to the outside of the second gripping rod 8, and the expander is fixed in time with the driving assembly without the need for re-debugging, which increases the flexibility of the operation process; a support frame 9 is welded on the inner wall of the second gripping rod 8, and the side of the cross bar away from the first gripping rod 1 passes through the support frame 9 and extends to the outside of the second gripping rod 8, and slides with the support frame 9;
[0033] The driving assembly includes a ratchet 10, which slides with the rack in a transverse cooperation. The bottom of the ratchet 10 is rotatably connected to the inner bottom wall of the support frame 9 by bolts. A pawl 15 is engaged with the side of the ratchet 10 away from the rack 6. The length of the cross bar 5 is greater than the distance between the first grip bar 1 and the second grip bar 8, which is convenient for the use of the operation process, so that the rack 6 is always engaged with the ratchet 10, thereby driving the ratchet 10 to rotate; the bottom of the other end of the pawl 15 is fixedly connected to the connecting rod 13 by bolts, and the support A sliding groove is provided on the inner side wall of the frame 9 near the first gripping rod 1, and a slider 12 is vertically slidably fitted in the sliding groove. A buckle 11 is bonded to the side wall of the slider 12 near the rack 6. A through groove for engaging the buckle 11 is provided in the sliding groove, and a silicone layer is bonded to the inner side wall of the through groove, so that when the connecting rod 13 drives the pawl 15 to break away from the motion track of the ratchet 10, the position of the connecting rod 13 is stabilized.

A through hole corresponding to the connecting rod 13 is provided; the end of the connecting rod 13 away from the slider 12 extends to the outside of the second gripping rod 8, and the extension length is greater than the diameter of the handle 7. The contact area between the operator and the handle 7 and the connecting rod 13 is increased, and it is easier to push the handle 7 during use, thereby improving the operator's experience when pushing the handle 7; a sliding component that can slidably cooperate with the driving component is provided between the first gripping rod 1 and the second gripping rod 8, so that when the gripping rod is gripped and moved inward, the ratchet 10 pawl 15 is synchronously driven. After adjusting the expansion width, it is directly engaged and fixed without unnecessary debugging. After the inspection is completed, the handle 7 is directly pushed upward to cancel the engagement of the pawl 15, reduce the expansion, and take out the dilator, thereby improving the convenience and flexibility during operation, and facilitating the doctor to operate the dilator and flashlight alone for inspection without the cooperation of an assistant.
[0035] The specific implementation process is as follows:
[0036] The lubricating piece is wrapped around the outside of the expansion component and engaged with the protrusion 3 on the top of the expansion component. The handle 7 is in the initial state, so the pawl 15 is engaged with the ratchet 10. The first grip 1 and the second grip 8 are gripped tightly, so that the expansion component is spread out to break the lubricating piece and squeeze out the lubricating oil in the lubricating piece, making it easier to put the expander into the diseased area. At the same time, the sliding component moves toward the first grip 1 due to the pulling force between the first grip 1 and the second grip 8, so that the rack 6 on the cross bar 5 drives the ratchet 10 to rotate. When the expansion width is adjusted, the first grip 1 is reduced. The pulling force of the second grip rod 8 causes the pawl 15 to engage with the ratchet 10 to fix the expansion width. After the inspection is completed, the handle 7 is pushed upward to engage with the through groove in the slide groove, so that the pawl 15 cancels the engagement with the ratchet 10 and leaves the rotation track of the ratchet 10, thereby causing the scattered expansion components to be retracted inwardly. During this period, no other operations are required, which improves the flexibility of operation during use. When the expansion components are retracted, since the edges of the expansion plates 2 are wrapped with silicone strips 4, the possibility of pinching the patient is avoided when closing. After the expander is completely closed, the expander can be taken out.
