Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a novel adjustable visual anal dilator. Background Art

[0002] When examining anorectal diseases, in order to intuitively understand the condition, a rectal dilator is needed to dilate the patient's anus. Rectal dilator, also known as anal canal dilation, refers to a method of anal dilation treatment under local anesthesia or general anesthesia. Rectal dilator is commonly used in anorectal disease examination, treatment and postoperative recovery. By dilating the anus, the internal and external sphincters of the anal canal are relaxed.

[0003] Most of the existing anal dilators are solid metal anal dilators, and their sizes are fixed and cannot be adjusted at any time according to the patient's own needs.

[0004] A utility model patent with Chinese patent publication number CN215084045U discloses an airbag-type anal dilator. The diameter of the cylindrical airbag can be adjusted by inflating and deflating the balloon, allowing the size to be adjusted according to the patient's needs. However, due to the deformable nature of the inflatable balloon column, the balloon must be inflated before insertion into the patient's anus. Insertion must be performed after inflation reaches a certain level, and then the inflation and deflation operations must be repeated. This is a cumbersome operation. Furthermore, if the inflated balloon has a large diameter, insertion becomes more difficult.

[0005] Moreover, the above-mentioned anal dilator only has the function of expanding and relaxing the patient's anus, and cannot be used for observation and inspection during the expansion and relaxation process. Summary of the Invention

[0006] In response to the problems pointed out in the background technology, the present invention proposes a new type of adjustable visual anal dilator, which is size-adjustable, easy to insert, and can be visualized.

[0007] The technical solution of the present invention is achieved as follows:

[0008] A novel adjustable visual anal dilator includes a tubular airbag sleeve and a tubular mirror tube. The front end of the mirror tube is closed, the airbag sleeve is arranged on the outer surface of the mirror tube, the two ends of the airbag sleeve are sealed with the mirror tube, and a closed inflatable space is enclosed between the airbag sleeve and the outer wall of the mirror tube.

[0009] The present invention is further configured such that a lens is provided inside the mirror tube, and a portion of the airbag sleeve corresponding to the lens is transparent.

[0010] By adopting the above technical solution, the endoscope tube has a slender structure, and the airbag sleeve is arranged on the endoscope tube. The endoscope tube with a slender structure is easy to insert and saves effort. In addition, the endoscope tube has a higher structural strength than the inflated airbag and will not deform, making it easy to insert into the patient's anus. After insertion, the airbag is inflated to adjust the size of the airbag. The lens arranged on the endoscope tube can take pictures of the inside of the patient's anus, making it convenient for doctors to observe and analyze the patient's condition.

[0011] Compared with the existing anal dilator with a pure airbag structure, the anal dilator of the present application is more convenient and labor-saving to insert, and has the function of observing the patient's internal organs.

[0012] The mirror tube and the lens are existing technologies. The micro lens is arranged in the mirror tube. A lighting lamp can also be arranged in the mirror tube to illuminate the shooting of the lens. The wires connected to the lens and the lighting lamp enter from the mirror tube.

[0013] The mirror tube can be a rigid structure or a bendable and deformable structure.

[0014] The present invention is further configured as follows: the airbag cover includes an airbag body, which is opened at both ends; the front end of the airbag body is connected to an end head for sealing the front end opening; the end head is connected to the front end of the mirror tube; an annular fixing ring is provided on the outer wall of the rear end of the mirror tube; the rear end of the airbag body is provided with an annular skirt; and also includes an annular fixing plate, which is fixedly connected to the fixing ring; the skirt of the airbag body is clamped and fixed between the fixing ring and the fixing plate; the airbag body, skirt, fixing ring, mirror tube, and end head form a closed inflation space; the fixing ring is provided with a valve mouth connected to the inflation space.

[0015] By adopting this technical solution, the airbag forms a detachable connection to the scope tube via the end cap and skirt, making the airbag cover disposable, requiring a new cover for each use. One end of the airbag body forms a detachable and sealed connection to the scope tube via the end cap, while the other end of the airbag body forms a detachable and sealed connection to the fixing ring on the scope tube via the skirt. This rationally designed structure facilitates assembly and disassembly.

[0016] The present invention is further configured such that the lens is arranged at the front end of the lens tube, and the end is transparent.

[0017] By adopting the above technical solution, the lens is set at the front end of the mirror tube, and the camera is taken through the transparent end. This method can be used to photograph and observe the insertion depth of the mirror tube.

[0018] The present invention is further configured such that the lens is arranged on the side wall of the lens tube, and the airbag body is transparent.

[0019] By adopting the above technical solution, the lens is set on the side wall of the mirror tube and takes pictures through the transparent airbag body. This method can shoot and observe the side of the inserted mirror tube, and the expansion of the airbag can squeeze and stretch the human tissue part, making it convenient for shooting and observation.

[0020] The present invention is further configured such that the lens is arranged on the side wall of the lens tube, an opening corresponding to the lens is provided on the airbag body, and a flexible transparent sheet is provided at the opening.

[0021] By adopting the above technical solution, the airbag body is only transparent at the position corresponding to the lens, so that the lens can shoot outward through the transparent sheet, making it convenient for medical staff to observe.

[0022] The present invention is further configured such that an inwardly concave receiving groove is provided on the outer side wall of the mirror tube, the receiving groove is arranged along the length direction of the mirror tube, an inwardly folded portion corresponding to the receiving groove is formed on the airbag body, and the inwardly folded portion is connected to the receiving groove.

[0023] By adopting the above technical solution, an inward folding portion is formed on the airbag body, and the inward folding portion is formed as an inward depression on the surface of the airbag body. The formation of the inward folding portion enables the airbag body to have good deformation and expansion capabilities, so that the size adjustment range of the anal dilator is larger.

[0024] The present invention is further configured such that the end head is provided with a threaded hole for connecting to the mirror tube.

[0025] By adopting the above technical solution, the end head is connected to the mirror tube through threads, which has a simple structure and is easy to assemble and disassemble.

[0026] The present invention is further configured such that a stud is provided on the fixing plate, a hole connected to the stud is provided on the fixing ring, a nut is threadedly connected to the stud, and a hole for the stud to pass through is provided on the skirt.

[0027] By adopting the above technical solution, the fixing ring and the fixing plate are fixedly connected by the studs and nuts, and the skirt is clamped and fixed between the fixing ring and the fixing plate, so that the skirt and the fixing ring form a sealing fit.

[0028] The present invention is further configured such that the transparent sheet includes an adhesive portion and a filling portion, the filling portion is adapted to be connected in the opening, and the adhesive portion is fixedly connected to the inner wall of the airbag body.

[0029] By adopting the above technical solution, the transparent sheet is arranged on the airbag body like a patch. The transparent sheet is composed of an adhesive portion and a filling portion, and is fixedly bonded to the airbag body by glue. The adhesive portion enables the transparent sheet to form a stable and firm connection with the airbag body, and the filling portion completely fills the open hole structure on the airbag body to avoid the formation of incomplete structural traces on the surface of the airbag body.

[0030] By adopting the above technical solution, the beneficial effects of the present invention are:

[0031] (1) Before inflation, the airbag is wrapped and attached to the endoscope tube, which is equivalent to inserting the endoscope tube into the patient's anus. The endoscope tube has a slender structure, making insertion easy and labor-saving.

[0032] (2) After insertion, the size of the air bag can be adjusted by inflating and deflating the air bag, so that the size of the anal dilator can be adjusted at will.

[0033] (3) A lens is provided on the mirror tube, through which the anus and internal organs of the human body can be observed, making it easier for doctors to observe and analyze the patient's condition. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The scope tube 1 can be made of metal or glass, or a flexible leather tube. The leather tube has a certain structural strength and requires a certain bending force to bend. The scope tube 1 is a long tubular structure. In this embodiment, the scope tube 1 is made of metal or glass.

[0052] The airbag cover 2 is a long tubular structure that fits over the outer surface of the scope tube 1. Both ends of the airbag cover 2 are sealed to the scope tube 1, forming a closed inflation space 3 between the airbag cover 2 and the outer wall of the scope tube 1. Before inflation, the airbag cover 2 is attached to the outer surface of the scope tube 1.

[0053] During use, the mirror tube 1 and the airbag cover 2 are inserted into the anus of the human body, and after being inserted into a suitable position, the airbag cover 2 is inflated. The airbag cover 2 can undergo elastic deformation after being inflated.

[0054] The scope tube 1 is provided with a lens 11, and the portion of the airbag cover 2 corresponding to the lens 11 is transparent. The lens 11 can be fixedly mounted inside the scope tube 1, or it can be movable, moving within the scope tube 1 or even outside the scope tube 1. When observation is required, the lens 11 is inserted into the scope tube 1 for use.

[0055] Before use, the airbag cuff is in an uninflated state and is attached to the scope tube, making it convenient for the airbag cuff to be inserted together with the scope tube. After insertion, the airbag cuff is inflated. The size of the inflated airbag cuff is controlled by the amount of inflation. The lens can shoot the human body through the transparent area on the airbag cuff.

[0056] The airbag sleeve 2 comprises a long, tubular airbag body 21 with openings at both ends. A cap 22 is connected to the front end of the airbag body 21 to seal the opening. The cap 22 is connected to the front end of the scope tube 1 and has a threaded hole 23 for connection to the scope tube 1. The front end of the cap 22 is hemispherical, and the outer wall of the front end of the scope tube 1 is provided with external threads. The cap 22 is threadedly connected to the front end of the scope tube 1, sealing the front end of the scope tube 1. One end of the airbag body 21 is sealed to the cap 22.

[0057] refer to Figure 5 An annular fixing ring 12 is provided on the outer wall of the rear end of the mirror tube 1. An annular skirt 24 is provided at the rear end of the airbag body 21. The airbag body 21 also includes an annular fixing plate 4, which is fixedly connected to the fixing ring 12. The skirt 24 of the airbag body 21 is clamped and fixed between the fixing ring 12 and the fixing plate 4. The fixing plate 4 is provided with a stud 41. The fixing ring 12 is provided with a hole connected to the stud 41. A nut 42 is threadedly connected to the stud 41. The skirt 24 is provided with a hole for the stud 41 to pass through.

[0058] The airbag body 21, skirt 24, fixing ring 12, mirror tube 1, and end 22 form a closed inflatable space 3. The fixing ring 12 is provided with a valve 5 connected to the inflatable space 3. The air in the inflatable space 3 can be inflated and released through the valve 5.

[0059] The end cap 22, the airbag body 21 and the skirt 24 are integrally provided and can be designed to be disposable.

[0060] The lens setting position on the mirror tube has the following implementation methods:

[0061] refer to Figure 7-8 In the first embodiment, the lens 11 is arranged at the front end of the lens tube 1, and the end 22 is transparent. The shooting direction of the lens is the same as the opening direction of the lens tube, which is along the axial direction of the lens 11.

[0062] refer to Figure 9-10 In the second embodiment, the lens 11 is disposed on the side wall of the lens tube 1, the airbag body 21 is transparent, made of a transparent rubber material, and the lens 11 is made of transparent glass. The shooting direction of the lens 11 is the same as the radial direction of the lens tube.

[0063] refer to Figure 9-10 In the third embodiment, the lens 11 is disposed on the side wall of the scope tube 1. The airbag body 21 is provided with an opening 27 corresponding to the lens 11. A flexible transparent sheet 6 is disposed at the opening 27. A guide hole 15 is provided on the scope tube 1, adjacent to the lens 11. The guide hole 15 is arranged radially along the scope tube 1. The transparent sheet 6 is provided with a guide post 16 that slidably engages with the guide hole 15. Since the airbag body 21 expands and deforms after inflation, this may cause the transparent sheet 6 to shift, misaligning the lens 11 with the transparent sheet 6 and affecting observation through the lens 11. Therefore, the guide post 16 of the aforementioned structure serves to position the transparent sheet 6, ensuring that the transparent sheet 6 and the lens 11 are always aligned.

[0064] In the above three embodiments, the lens 11 is preferably fixed. The lens 11 can be a miniature camera or a miniature camera head. The circuit structure and power supply structure related to the lens 11 can be arranged in the lens tube 1 and pass through the lens tube 1.

[0065] refer to Figure 13 At the same time, the lens 11 can also be set up to be movable, such as fixing the lens 11 to one end of a long movable rod 06, and the movable rod 06 can be extended into the lens tube 1 or moved out of the lens tube 1. In this solution, the movable rod 06 and the lens 11 are used as an external accessory and are used when observation is needed.

[0066] refer to Figure 11 The transparent sheet 6 includes an adhesive portion 61 and a filling portion 62. The filling portion 62 is adapted to be connected to the opening 27, and the adhesive portion 61 is fixedly connected to the inner wall of the airbag body 21. The filling portion 62 fills the opening 27 to prevent a dent from forming on the airbag body 21.

[0067] The outer wall of the scope tube 1 is provided with a concave receiving groove 71, which extends along the length of the scope tube 1. The airbag body 21 is formed with an inwardly folded portion 72 corresponding to the receiving groove 71, and the inwardly folded portion 72 is connected to the receiving groove 71. In this structure, the airbag body 21 is formed with multiple inwardly folded portions 72, which are spaced apart circumferentially around the airbag body 21. The provision of the inwardly folded portions 72 facilitates expansion of the airbag body 21 after inflation. When not inflated, the receiving groove 71 accommodates the inwardly folded portions 72.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
