Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of genital opening devices, and more specifically, to an open genital opening device. Background Technology
[0002] A cloacal sphincter is a device used to open the reproductive tract of an animal, facilitating the insertion of medical instruments. The cloacal sphincter used on giant pandas has a unique structure, consisting of two parts: a cylindrical insertion tube and a disc-shaped outer ring with a central hole.
[0003] Once the genital speculum is inserted into the panda's reproductive vestibule, various instruments will enter the urethra and vagina through the central hole of the outer ring and the connecting tube to it for further procedures. For safe and convenient insertion into the panda's reproductive vestibule, the diameter of the insertion tube needs to be kept relatively small. With the development of medical technology, the types and models of various medical instruments are also rapidly evolving to meet the ever-increasing demands of medical examinations. Traditionally, the panda genital speculum is mainly used to assist in the insertion of artificial insemination tubes and urinary catheters. Both of these instruments have very small diameters, and after insertion into the appropriate location, the genital speculum can be withdrawn directly from the end of the instrument.
[0004] Currently, when instruments with large tips or handles are needed, the diameter of the genital speculum insertion tube is smaller than the widest part of the instrument tip or handle. This prevents the genital speculum from being withdrawn from the tip after insertion. Within the very limited space of the genital vestibule, without withdrawing the genital speculum, the operating space for these instruments is severely restricted, making it impossible to complete subsequent related medical activities. Utility Model Content
[0005] The purpose of this invention is to provide an open genital opening device that allows for easy removal of the entire device, even when dealing with medical devices with large distal handles.
[0006] This utility model is achieved through the following technical solution: The open genital opening device of this utility model includes an insertion tube, an annular outer ring disposed at one end of the insertion tube, a long strip-shaped first through hole opened on the side of the insertion tube, and a long strip-shaped second through hole opened on the side of the outer ring; the first through hole and the second through hole are connected, the length of the first through hole is equal to the length of the insertion tube, and the length of the second through hole is equal to the width of the outer ring.
[0007] Furthermore, the outer ring has a tapered structure, and the end of the outer ring with a smaller diameter is connected to the end of the insertion tube.
[0008] Furthermore, a pair of first grips are provided on the outer side of the outer ring, and the pair of first grips are respectively provided on both sides of the second through hole; the gap width between the pair of first grips is equal to the width of the second through hole.
[0009] Furthermore, the pair of first grips are parallel to each other, and the length direction of the first grips is perpendicular to the axial direction of the insertion tube.
[0010] Furthermore, a first baffle is provided in the first through hole, a second baffle is provided in the second through hole, and a second handle is provided between a pair of first handles; the first baffle, the second baffle, and the second handle are connected end to end in sequence.
[0011] Furthermore, a C-shaped limiting piece is provided on the inner side of the first baffle, and the outer side of the limiting piece is attached to the inner wall of the insertion tube; the width of the opening of the limiting piece is equal to the width of the first through hole.
[0012] Furthermore, multiple limiting pieces are provided, and the multiple limiting pieces are evenly distributed along the length direction of the first baffle.
[0013] Furthermore, it also includes rubber rings that are simultaneously fitted onto the outside of the pair of first baffles and second baffles.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the open genital opening device of this utility model involves inserting an insertion tube into the reproductive vestibule of a giant panda, with the outer ring located externally and attached to the opening of the reproductive tract. The reproductive tract is temporarily opened by the insertion tube. Then, medical instruments (such as urinary catheters) are inserted into the giant panda's body through the insertion tube. Once inserted to the appropriate location, the insertion tube can be withdrawn from the reproductive vestibule. The medical instruments are then aligned with the first and second through holes, allowing them to pass directly through them. This also facilitates the complete withdrawal of the insertion tube, even for medical instruments with large diameters or lengths at the tip, avoiding interference with subsequent operations. Furthermore, the insertion tube and outer ring completely retain the original reproductive tract dilation function. Attached Figure Description

[0022] Example
[0023] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 6 As shown, the open genital opening device of this embodiment includes an insertion tube 1, an annular outer ring 2 disposed at one end of the insertion tube 1, a long strip-shaped first through hole 3 opened on the side of the insertion tube 1, and a long strip-shaped second through hole 4 opened on the side of the outer ring 2; the first through hole 3 and the second through hole 4 are connected, the length of the first through hole 3 is equal to the length of the insertion tube 1, and the length of the second through hole 4 is equal to the width of the outer ring 2. Specifically, the design of the first through-hole 3 and the second through-hole 4 creates an opening structure between the insertion tube 1 and the outer ring 2. During use, the insertion tube 1 is inserted into the giant panda's reproductive vestibule, with the outer ring 2 located externally and attached to the opening of the reproductive tract. The reproductive tract is temporarily opened by the insertion tube 1. Then, medical instruments (such as urinary catheters) are inserted into the giant panda's body through the insertion tube 1. Once inserted to the appropriate location, the insertion tube 1 can be withdrawn from the reproductive vestibule. The medical instrument is then aligned with the first through-hole 3 and the second through-hole 4, allowing it to pass directly through them. This also allows for easy and complete withdrawal of the insertion tube 1, even for instruments with large diameters or lengths at the tip, avoiding interference with subsequent procedures. Furthermore, the insertion tube 1 and the outer ring 2 retain their original reproductive tract dilation function.
[0024] In this embodiment, the outer ring 2 is a tapered structure, and the smaller diameter end of the outer ring 2 is connected to the end of the insertion tube 1.
[0025] In this embodiment, a pair of first handles 5 are provided on the outer side of the outer ring 2, and the pair of first handles 5 are respectively located on both sides of the second through hole 4; the gap width between the pair of first handles 5 is equal to the width of the second through hole 4. The pair of first handles 5 are parallel to each other, and the length direction of the first handles 5 is perpendicular to the axial direction of the insertion tube 1. Specifically, the first handles 5 make it easier to insert the insertion tube 1 into the reproductive tract and subsequently pull it out. The insertion tube 1, outer ring 2, and first handles 5 can be an integral structure, which can be made of glass or stainless steel, etc.
[0026] In this embodiment, a first baffle 6 is provided in the first through hole 3, a second baffle 7 is provided in the second through hole 4, and a second handle 8 is provided between a pair of first handles 5; the first baffle 6, the second baffle 7, and the second handle 8 are connected end to end in sequence. Specifically, the function of the first baffle 6 is to be locked in the first through hole 3 to prevent tissue from the inner wall of the vulva from getting stuck in the first through hole 3, and to prevent the medical device from contacting and damaging the inner wall tissue when it is inserted into the insertion tube 1. Furthermore, the first baffle 6, the second baffle 7, and the second handle 8 are an integral structure (as shown in the attached figure). Figure 6 As shown in the diagram, it can be directly separated from the insertion tube 1, the outer ring 2, and the first grip 5. During operation, the first grip 5 and the second grip 8 need to be held simultaneously.
[0027] In this embodiment, a C-shaped limiting piece 9 is provided on the inner side of the first baffle 6, and the outer side of the limiting piece 9 is attached to the inner wall of the insertion tube 1; the width of the opening of the limiting piece 9 is equal to the width of the first through hole 3. Specifically, see attached... Figure 6 As shown, the function of the limiting piece 9 is to be stuck in the inner wall of the insertion tube 1, and to support and restrict the first baffle 6, so that the first baffle 6 can only move along the axial direction of the insertion tube 1, and will not fall into the insertion tube 1 or fall out of the first through hole 3.
[0028] In this embodiment, multiple limiting pieces 9 are provided, and the multiple limiting pieces 9 are evenly distributed along the length direction of the first baffle 6. Specifically, the insertion tube 1 and the first baffle 6 are pulled out simultaneously, and then the first baffle 6 is pulled out from the insertion tube 1 (as shown in the attached figure). Figure 3 As shown), move the first baffle 6 so that the medical device passes through the opening on the limiting piece 9, then remove the first baffle 6, and then remove the insertion tube 1.
[0029] In this embodiment, a rubber ring 10 is also included, which is simultaneously fitted onto the outside of a pair of first baffles 6 and second baffles 7. Specifically, by simultaneously fitting the rubber ring 10 onto the first grip 5 and the second grip 8, the two can be temporarily fixed in place.
[0030] In summary, the open genital speculum of this embodiment involves inserting the insertion tube 1 into the panda's reproductive vestibule, with the outer ring 2 located externally and attached to the opening of the reproductive tract. The reproductive tract is temporarily opened by the insertion tube 1. Medical instruments (such as urinary catheters) are then inserted into the panda's body through the insertion tube 1. Once inserted to the appropriate location, the insertion tube 1 can be withdrawn from the reproductive vestibule. The medical instruments are then aligned with the first through-hole 3 and the second through-hole 4, allowing them to pass directly through these openings. This also facilitates the complete withdrawal of the insertion tube 1, even for instruments with large diameters or lengths, avoiding interference with subsequent procedures. Furthermore, the insertion tube 1 and the outer ring 2 fully retain their original reproductive tract dilation function.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
