Description

Technical Field

[0001] The utility model relates to an auxiliary device for cervical human papillomavirus examination. Background Technique

[0002] Human papillomavirus is also known as HPV virus. The examination method usually adopts the HPV detection of cervical exfoliated cells. The HPV detection of cervical exfoliated cells is currently a routine screening method for cervical cancer and its precancerous lesions in clinical practice. This examination is not applicable to female patients without a history of sexual intercourse. The examination needs to avoid the menstrual period and be carried out after the menstruation is completely clean. In addition, sexual intercourse, vaginal medication, vaginal douching, etc. should be avoided three days before the examination. During the examination, the patient lies flat on the examination bed, with the legs separated and placed on the leg bracket to fully expose the perineum. The doctor uses a speculum to expose the cervix, rotates a special sampling brush inside the cervical orifice for several weeks to take samples, then places the sampling brush in a special specimen bottle and sends it to the pathology department for the pathologist to detect and judge.

[0003] Generally, the anterior and posterior walls of a female's vagina are in a mutually closed state. If a gynecological examination is needed, a speculum needs to be used to open the vagina to fully expose the vagina and cervix for convenient sampling and detection of the patient's cervical orifice. The existing speculum usually consists of upper and lower speculum blades in the shape of a duck's bill and a handle. After the closed upper and lower speculum blades are inserted into the vagina, it is necessary to control the opening between the upper and lower speculum blades. After the opening angle is determined, a locking device is used to fix the angle between the upper and lower speculum blades, resulting in an inability to accurately adjust the range of the expansion angle. Once the doctor makes a mistake and the expansion angle is too large, it will make the patient very uncomfortable and even cause harm to the patient. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary device for cervical human papillomavirus examination to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0025] In addition, for a better description of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0026] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, a cervical human papillomavirus inspection aid includes a first vaginal dilator 1, a second vaginal dilator 2, a first handle 101, a second handle 201, a ratchet plate 4, a one-way locking member, and a limit component.

[0027] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , including;

[0028] The first vaginal dilator 1 and the second vaginal dilator 2 in the shape of a duckbill, the first vaginal dilator 1 and the second vaginal dilator 2 are hinged at one end away from the pointed mouth, and the first handle 101 and the second handle 201 are respectively arranged at one end away from the pointed mouth of the first vaginal dilator 1 and the second vaginal dilator 2. It further includes the ratchet plate 4 installed on the first handle 101 and adapted to the one-way locking member rotatably arranged on the second handle 201;

[0029] The limiting component is installed on the second handle 201 and can be inserted into the one-way locking piece to limit the rotation of the one-way locking piece.

[0030] Wherein, one end of the first vaginal speculum 1 and the second vaginal speculum 2 away from the spout is rotatably connected through a hinge shaft 3.

[0031] Preferably, a through hole 202 is provided at one end of the second vaginal speculum 2 away from the spout. After the first vaginal speculum 1 and the second vaginal speculum 2 are opened in the vagina, the sampling brush can extend into the vagina through the through hole 202 to perform sampling detection work on the vagina.

[0032] Specifically, in this embodiment, when using the cervical human papillomavirus inspection aid of the present utility model, after cleaning the perineum of the patient, the first vaginal speculum 1 and the second vaginal speculum 2 with a spout are inserted into the vagina. At this time, the first vaginal speculum 1 and the second vaginal speculum 2 are in a closed state. The first vaginal speculum 1 and the second vaginal speculum 2 are slowly pushed into the vagina. By slowly controlling the deflection of the second handle 201 relative to the first handle 101, the first vaginal speculum 1 and the second vaginal speculum 2 are opened in the vagina, and the angle between the first vaginal speculum 1 and the second vaginal speculum 2 is adjusted according to the size of the patient's vaginal orifice. And the angle between the first vaginal speculum 1 and the second vaginal speculum 2 can be fixed when the control is stopped to realize the dilation of the vagina and assist the subsequent sampling brush to sample the vagina.

[0033] Wherein, when controlling the deflection of the second handle 201 relative to the first handle 101, the one-way locking piece is driven to deflect synchronously in the direction of the first handle 101. At this time, the one-way locking piece and the ratchet plate 4 are always in a meshing state, and the limiting component is inserted into the one-way locking piece. The one-way locking piece can only revolve around the hinge shaft 3 as the center and cannot rotate itself, so as to facilitate the accurate control of the opening angle between the first vaginal speculum 1 and the second vaginal speculum 2 and prevent the angle from changing under the extrusion of the vagina.

[0034] Preferably, the ratchet plate 4 is arranged in an arc structure, and the ratchet plate 4 is designed with the hinge shaft 3 as the center.

[0035] Preferably, a plurality of ratchet teeth 401 are equidistantly distributed on the ratchet plate 4, and a plurality of grooves adapted to the ratchet teeth 401 are provided. The ratchet teeth 401 are rotatably installed in the grooves. Wherein, a spring piece is arranged between the groove and the ratchet teeth 401. When the one-way locking piece revolves in the direction of the first handle 101, it meshes with the ratchet teeth 401, and under the action of the spring piece, the ratchet teeth 401 can yield.

[0036] Please refer to Figure 4, the one-way locking member includes a connecting shaft 5 rotatably mounted on the second handle 201, a ratchet wheel 6 meshing with the ratchet plate 4 is arranged on the connecting shaft 5, and the ratchet wheel 6 is arranged as a semi-ratchet wheel.

[0037] It should be noted that under the meshing cooperation of the ratchet wheel 6 and the ratchet plate 4, precise control of the angle between the first vaginal dilator 1 and the second vaginal dilator 2 is achieved.

[0038] Preferably, at least one set of limiting holes 501 is formed on the outer wall of the connecting shaft 5.

[0039] Please refer to Figure 5 and Figure 6 , the limiting component includes a plugging sleeve 7 installed at the side end of the second handle 201, a cylindrical cavity is formed in the plugging sleeve 7, a plugging shaft 8 is slidably arranged in the cylindrical cavity, and one end of the plugging shaft 8 away from the plugging sleeve 7 can be inserted into the limiting hole 501;

[0040] It further includes a spring 9, the spring 9 is arranged in the cylindrical cavity, one end of the spring 9 abuts against the top of the cylindrical cavity, and the other end abuts against the plugging shaft 8.

[0041] A push plate 10 is slidably arranged on the second handle 201, and the push plate 10 is connected to the plugging shaft 8.

[0042] Specifically, when adjusting the angle between the first vaginal dilator 1 and the second vaginal dilator 2, the plugging shaft 8 is inserted into the limiting hole 501. Under the limiting action of the plugging shaft 8, the connecting shaft 5 cannot rotate self - sufficiently to fix the angle between the first vaginal dilator 1 and the second vaginal dilator 2. Among them, when manually stopping controlling the deflection between the first vaginal dilator 1 and the second vaginal dilator 2, the second vaginal dilator 2 is locked under the meshing of the ratchet plate 4 and the ratchet wheel 6.

[0043] In the initial state, the spring 9 is in a compressed state, generating a force on the plugging shaft 8 towards the limiting hole 501. At this time, the end of the plugging shaft 8 abuts against the inner bottom of the plugging sleeve 7. Even if the spring 9 is still in a compressed state, the plugging shaft 8 cannot move deeper into the limiting hole 501 relative to the plugging sleeve 7. When the plugging shaft 8 is inserted into the limiting hole 501, the spring 9 is still in a compressed state, making the connecting shaft 5 unable to rotate. After the vaginal dilation is completed, the push plate 10 can be manually driven to move relative to the second handle 201, driving the plugging shaft 8 to move towards the plugging sleeve 7, so that the plugging shaft 8 is disengaged from the limiting hole 501, realizing the free rotation of the connecting shaft 5, releasing the locking of the second vaginal dilator 2, and restoring the closing of the first vaginal dilator 1 and the second vaginal dilator 2.
