Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, and in particular to a novel uterine manipulator. Background Art

[0002] Uterine manipulator is mainly used for total or subtotal hysterectomy. Currently, it is used for female patients with non-atrophic cervix, such as Figure 1 As shown, the existing uterine lifting cup can be used for uterine lifting, targeting postmenopausal female patients with cervical atrophy, with atrophic cervix 5, as shown in FIG. Figure 2 As shown, due to cervical atrophy or occlusion of the external cervical os, there is no obvious boundary between the exposed cervix and the anterior and posterior walls of the vagina. The existing uterine lifting cup for normal adults cannot be placed and fixed, resulting in the inability to perform uterine lifting. During the operation, due to the lack of the uterine lifting function of the uterine elevator, the gaps between the cervix, vagina, bladder and rectum are easily folded, and the gaps between the cervix, bladder and rectum cannot be pushed open well, which greatly increases the difficulty of the operation and the risk of injury to the bladder, ureter and rectum. Although some patients use a large amount of gauze to fill the vagina before the operation to push the uterus up and expose the gap, it is not very practical. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a new type of uterine manipulator that can be used for female patients with cervical atrophy after menopause. Through the setting of the suction cup, it can be fixedly adsorbed on the anterior and posterior walls of the atrophied cervix and the top of the vagina, so as to play the role of fixing the atrophied cervix and the top of the vagina. When the uterine manipulator is pushed inward, the gaps between the cervix, vagina, bladder and rectum can be fully expanded, avoiding the folding of the gaps, which increases the difficulty of the operation and the risk of injury to the bladder, ureter and rectum.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a new type of uterine lifter, including a vertical rod and a suction cup fixed at the top end of the vertical rod. The suction cup is coaxially arranged with the vertical rod, and the suction cup is used to fix and adsorb on the atrophic cervix and the front and back walls of the top vagina.

[0005] Furthermore, the vertical rod is a metal rod in the shape of a long strip.

[0006] Furthermore, a horizontal bar is fixedly provided at the lower portion of the vertical bar, and the horizontal bar is arranged perpendicular to the vertical bar.

[0007] Furthermore, the distance between the bottom ends of the horizontal bar and the vertical bar is 8-12 cm, and gripping sections are formed on both sides of the vertical bar on the horizontal bar, and the lengths of the two gripping sections are consistent.

[0008] Furthermore, the crossbar is a metal rod in the shape of a long strip.

[0009] Further, the uterus rod is detachably mounted on the suction cup at one end, and the uterus rod is coaxially arranged with the vertical rod, and when the external cervical os is visible, the uterus rod can pass through the external cervical os and enter the uterine cavity of the uterine body.

[0010] Further, a connecting screw hole is arranged at the center of the inner surface of the suction cup, and a connecting screw column is fixedly arranged at one end of the uterus rod, the connecting screw column is matched with the connecting screw hole, and the connecting screw column is threadedly connected in the connecting screw hole.

[0011] Further, the diameter of the uterus rod is 1-4mm, and the length of the uterus rod is 3-7cm.

[0012] Further, the uterus rod is in a strip shape, and the top end of the uterus rod is in a round head shape.

[0013] As can be seen from the above description, the novel uterus holder has the following beneficial effects: for some patients after menopause, full hysterectomy is needed due to cervical atrophy, and after cervical atrophy, there is no boundary between the anterior and posterior walls of the vagina, and a flat structure is formed, thus, through the arrangement of the suction cup, the atrophic cervix and the anterior and posterior walls of the top vagina can be fixed and adsorbed, so as to fix the atrophic cervix and the top vagina, and when the vertical rod is pushed inwards, the corresponding uterus lifting effect can be achieved, thereby solving the problem that the existing uterus cup cannot be placed and the uterus is lifted for female patients with cervical atrophy after menopause, and during the process of pushing the uterus holder inwards, the gap between the cervix, vagina, bladder and rectum can be fully expanded, so as to avoid the increase of surgical difficulty and the risk of bladder, ureter and rectum injury.

[0022] The present application will be further described by the specific embodiments.

[0023] Embodiment one

[0024] As shown in Figure 3 and Figure 4 , the novel uterine manipulator comprises a vertical rod 1 and a suction cup 2 fixedly arranged at the top end of the vertical rod 1, the suction cup 2 is coaxially arranged with the vertical rod 1, and the suction cup 2 is used for fixedly adsorbing with the atrophic cervix 5 and the top end of the vagina 7.

[0025] Since part of the patients after menopause need to perform total hysterectomy due to cervical atrophy, the cervix after atrophy has no boundary with the front and back walls of the vagina 7, and presents a flat structure. Therefore, through the arrangement of the suction cup 2, the atrophic cervix 5 and the top end of the vagina 7 can be fixedly adsorbed, so as to fix the atrophic cervix 5 and the top end of the vagina 7. When the vertical rod 1 is pushed inward, the corresponding uterine lifting effect can be achieved, thereby the problem that the existing uterine cup cannot be placed and the uterus cannot be lifted for the female patients with cervical atrophy after menopause can be solved. During the process of pushing the uterine manipulator inward, the gap between the cervix, the vagina 7, the bladder and the rectum can be fully expanded, so as to avoid the increase of surgical difficulty and the risk of bladder, ureter and rectum injury caused by the folding of the gap.

[0026] Correspondingly, the suction cup 2 can be made of medical silica gel or rubber material. When in use, the suction cup 2 can be fixedly adsorbed on the atrophic cervix 5 and the top end of the vagina 7 by applying pressure and extruding the gas in the suction cup 2. After hysterectomy, the uterine manipulator and the removed uterus can be separated in vitro.

[0027] Preferably, the vertical rod 1 is a metal rod and has a long strip shape, and in addition, the vertical rod 1 also has a cylindrical shape.

[0028] In addition, a cross bar 3 is fixedly provided at the lower part of the vertical rod 1. The cross bar 3 is arranged perpendicular to the vertical rod 1. The distance between the cross bar 3 and the bottom end of the vertical rod 1 is 8-12 cm. The cross bar 3 is formed with gripping sections 31 on both sides of the vertical rod 1. The lengths of the two gripping sections 31 are consistent. Therefore, through the setting of the cross bar 3, when the uterine manipulator is pushed with force, the force of pushing the uterine manipulator can be better grasped by holding the two gripping sections 31 of the cross bar 3.

[0029] Preferably, the cross bar 3 is a metal bar in the shape of an elongated strip. In addition, the cross bar 3 is also in the shape of a cylinder.

[0030] Example 2

[0031] like Figures 5 to 7 As shown, the difference between this embodiment and embodiment 1 is that: on the basis of embodiment 1, the uterine manipulator also includes a uterine rod 4, one end of which is detachably mounted on the suction cup 2, and the uterine rod 4 is coaxially arranged with the vertical rod 1. When the external cervical os 51 is visible, the uterine rod 4 can pass through the external cervical os 51 and enter the uterine cavity 61 of the uterine body 6.

[0032] For patients whose external cervical os 51 is visible and not completely closed, through the setting of the uterine rod 4, the uterine rod 4 can pass through the external cervical os 51 and enter the uterine cavity 61 of the uterine body 6, which can support the uterine cavity 61 and facilitate the swinging of the position of the uterine body 6 during the operation. When the external cervical os 51 is not visible, the uterine rod 4 can be easily removed from the suction cup 2. The uterine rod 4 is not used and is only fixed to the front and back walls of the atrophic cervix 5 and the top of the vagina 7 by the suction cup 2 to fix the atrophic cervix 5 and the top of the vagina 7.

[0033] Correspondingly, a connecting screw hole 21 is provided at the center of the inner surface of the suction cup 2, and a connecting stud 41 is fixedly provided at one end of the uterine rod 4, and the connecting stud 41 is adapted to the connecting screw hole 21. The connecting stud 41 is threadedly connected to the connecting screw hole 21, thereby facilitating the rapid disassembly and assembly between the uterine rod 4 and the suction cup 2, and at the same time can well ensure the stability of the connection between the uterine rod 4 and the suction cup 2. In addition, in other embodiments, the connecting screw hole 21 extends downward to the top end of the vertical rod 1.

[0034] Preferably, the diameter of the uterine rod 4 is 1-4 mm, and the length of the uterine rod 4 is 3-7 cm. In actual use, uterine rods 4 of different diameters and lengths can be selected for use to better adapt to the inner diameter of the external cervical os 51 and the depth of the uterine cavity 61 of the uterine body 6.

[0035] Preferably, the uterine rod 4 is in the shape of a long strip, the top end of the uterine rod 4 is in the shape of a round head, and the uterine rod 4 is in the shape of a cylinder.

[0036] Other technical features are specifically the same as the first embodiment.

[0037] The above is only some specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any non-essential changes made by using this concept should be considered as an infringement of the protection scope of the present application.
