[0002] Endometrial cancer ranks third among malignant tumors of the female reproductive tract in China and first among cancers of the female reproductive system; the safety of endoscopic treatment of endometrial cancer is still controversial; existing research believes that laparoscopic resection of the uterus and adnexa is safe; for example, there is no significant difference in the main complications between abdominal hysterectomy, laparoscopic-assisted vaginal hysterectomy, and total laparoscopic hysterectomy; however, laparoscopic surgery can reduce surgery-related complications, shorten the hospital stay, reduce pain, and have a quick recovery; for tumor safety considerations, the tumor-free technique in minimally invasive surgery is crucial, and the uterine elevator is an indispensable instrument for laparoscopic total hysterectomy, subtotal hysterectomy, and radical total hysterectomy in gynecology; during laparoscopic total hysterectomy, the entire uterine cervix needs to be circumferentially dissected. When dissecting the uterine cervix, in order to expose the uterine cervix at the operation site, the assisting surgeon needs to cooperate with the operating surgeon.
[0003] Currently, the existing uterine elevation devices in the prior art only have a small range of uterine elevation and dilation of the cervical position, and cannot achieve a large range of dilation of the uterine cavity, thus greatly affecting the surgical field of view and operation. Therefore, a uterine elevation device for endometrial cancer is proposed. Content of the Utility Model

[0024] Please refer to Figures 1 - 3, An intrauterine cancer uterine elevation device, comprising a sleeve 1, inside which an inner cylinder 2 is slidably connected. Among them, a cavity 8 is provided inside the sleeve 1, and an opening 13 is provided between the cavity 8 and the top wall of the sleeve 1. Among them, the top of the inner cylinder 2 extends to the top of the sleeve 1 through the opening 13. Among them, the bottom of the sleeve 1 is open, so that the inner cylinder 2 can be installed upward into the inside of the sleeve 1 from the open end at the bottom of the sleeve 1. Among them, limiting grooves 15 are vertically opened on two opposite inner walls of the cavity 8, and limiting blocks 14 are installed on two separated side walls of the inner cylinder 2. Among them, the two limiting blocks 14 are respectively slidably connected with the two limiting grooves 15, so that the inner cylinder 2 can only move up and down inside the sleeve 1 and cannot rotate, thus achieving the effect of limiting the inner cylinder 2. An air delivery pipe 12 is connected inside the inner cylinder 2. The top of the air delivery pipe 12 is connected with an airbag 10, and the bottom of the air delivery pipe 12 is connected with a three-way joint 5. An air inlet valve 6 and an air release valve 4 are respectively connected to the three-way joint 5. Thus, air can be delivered to the airbag 10 through the air inlet valve 6 and the air delivery pipe 12, and then the airbag can be collided. Furthermore, through the inflated airbag 10, the effect of lifting the uterus is achieved. By adjusting the air delivery volume, the size of the airbag can be conveniently adjusted, thus achieving the effect of conveniently adjusting the area of the tray. Four elastic plates 9 are evenly installed at the top of the inner cylinder 2. Among them, the airbag 10 is located inside the four elastic plates 9. Among them, the four elastic plates 9 are all vertically installed at the edge of the inner cylinder 2. When the airbag 10 is inflated and expanded, the elastic plates 9 can open the space required for the airbag 10 to increase, thus facilitating the expansion of the airbag 10. When the airbag 10 deflates, through the elasticity of the elastic plates 9, the airbag 10 can deflate quickly until the elastic plates 9 are in a vertical state, thus facilitating the inner cylinder 2 to be completely withdrawn from the bottom of the sleeve 1, and thus facilitating the cleaning and disinfection of the airbag 10.
[0025] In this embodiment, a connecting block 11 is installed at the top of the inner cylinder 2. Among them, the airbag 10 is installed on the connecting block 11. Among them, the air delivery pipe 12 passes through the connecting block 11 and extends into the inside of the airbag 10. Through the connecting block 11, the installation of the airbag 10 is made more stable, avoiding the situation of the airbag 10 falling off.
[0026] In this embodiment, a limiting ring 7 is installed on the outer wall of the inner cylinder 2. Among them, the limiting ring 7 is located below the sleeve 1. When the airbag 10 expands to a certain size, the sleeve 1 will be limited between the side wall of the elastic plate 9 and the limiting ring 7, so that the device can form a whole, avoiding the situation of displacement between the sleeve 1 and the inner cylinder 2. At the same time, it can also prevent the situation of the inner cylinder 2 sliding out from the top of the sleeve 1.
[0027] In this embodiment, a rubber sleeve 3 is sleeved on the outer wall of the sleeve 1. Through the rubber sleeve 3, the friction between the hands of medical staff and the sleeve 1 can be effectively increased, thus avoiding the situation of sliding when holding the sleeve 1, and further avoiding the situation of the uterus moving during the lifting process.
[0028] Working principle: Install the inner cylinder 2 from the bottom of the sleeve 1 into the inside of the sleeve 1, then insert the sleeve 1 into the patient's vagina. After reaching the designated position, open the air inlet valve 6 to inflate the airbag 10, and then the airbag 10 expands. When the airbag 10 is fully inflated to lift the uterus, close the air inlet valve 6 to achieve the effect of lifting the uterus. After the operation is completed, open the air release valve 4 to deflate the airbag 10. Through the elastic force of the four elastic plates 9 rebounding, the airbag 10 can be quickly compressed, so that the inner cylinder 2 can be withdrawn from the bottom of the sleeve 1, which is convenient for cleaning and disinfecting the airbag 10.
[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
