Description

TECHNICAL FIELD

[0001] The utility model relates to surgical auxiliary device technical field, specifically, relate to a kind of in-vivo tumor overflow pollution device of prevention of cervical cancer surgery. BACKGROUND

[0002] Tumor tissue overflow is often inevitable when the vaginal wall is disconnected during cervical cancer surgery, leading to iatrogenic tumor dissemination and possibly leading to tumor recurrence, especially in laparoscopic surgery. A prospective multicenter study has confirmed that laparoscopic surgery leads to an increased recurrence rate and decreased survival rate in patients with early-stage cervical cancer. The current cervical cancer guidelines do not recommend laparoscopic surgery for early-stage cervical cancer surgery, which to some extent has caused the cervical cancer surgery approach to regress to the level of 20-30 years ago, seriously lagging behind the development of surgical technology. Even if the ligation method is used to avoid tumor overflow, for the vast majority of exophytic tumors, there is still a risk of tumor scattering into the vagina and exposure to the surgical field after incision.

[0024] Embodiment

[0025] Please refer to Figures 1-3 The embodiment provides a kind of in-cervical cancer operation to prevent tumor overflow pollution device, including installation ring 2 and the protective bag 1 of top opening, installation ring 2 is located at protective bag 1 opening and is connected with protective bag 1, installation ring 2 top is equipped with adhesive layer 3;It also includes pusher assembly, pusher assembly and installation ring 2 bottom abut.The adhesive layer 3 of this embodiment can use medical tissue glue.

[0026] In use, the medical staff can hold the pushing assembly, move the mounting ring 2 and the protective bag 1 into the vagina of the patient as a whole, move the mounting ring 2 and sleeve it outside the cervical tumor under the direct vision of the medical staff, so that the cervical tumor can be wrapped as a whole by the protective bag 1. Meanwhile, the medical staff applies a certain pressure to make the pushing assembly push the mounting ring 2 to tightly abut against the normal vaginal wall at the edge of the cervical tumor of the patient, at this time, the adhesive layer 3 is adhered to the normal vaginal wall at the edge of the cervical tumor of the patient, and after standing for about five minutes until the adhesion is firm, the pushing assembly can be moved outwards.

[0027] The application adopts the transvaginal direct vision non-invasive tumor wrapping, and has strong operability and effectiveness. By using the good adhesion of the existing medical tissue glue and tightly wrapping the tumor by the protective bag 1, the possibility of iatrogenic tumor pollution of the wound surface during the operation is effectively avoided.

[0028] Compared with the intraoperative ligation technology or preoperative pre-disconnection of the vaginal wall to wrap the cervix adopted by most current operators, the product can non-invasively and simply and effectively solve the problem of tumor overflow and pollution of the wound surface when the cervical cancer is disconnected from the vaginal wall.

[0029] The disposable device (the product is divided into large, medium and small sizes according to the tumor size and the vaginal width) is easy to manufacture and simple and convenient to operate, and the medical tissue glue is an existing marketized medical product.

[0030] The clinical practical value is great, and it is expected to return the early cervical cancer (<4cm) surgery to the minimally invasive era. Moreover, due to the strict non-tumor measure, part of the large tumor (4-5cm diameter lesion) can also be performed minimally invasively.

[0031] As shown in Figures 1-2 some embodiments of the application, the mounting ring 2 adopts a silica gel ring, the mounting ring 2 is provided with a mounting groove 4 at the top, and the adhesive layer 3 is embedded in the mounting groove 4. By arranging the mounting groove 4, the adhesive layer 3 is conveniently mounted. By arranging the mounting ring 2 to adopt a silica gel ring, the silica gel ring can be deformed. When the medical tissue glue is used, the mounting ring 2 can be slightly extruded and deformed when the medical staff applies a certain pressure to make the mounting ring 2 tightly abut against the normal vaginal wall at the edge of the cervical tumor of the patient, so that the medical tissue glue can overflow from the mounting groove 4, the contact area of the tissue glue is increased, and the adhesion and fixation are facilitated.

[0032] As shown in Figures 1-3 some embodiments of the application, the pushing assembly comprises a pushing sleeve 5 with an open top, the pushing sleeve 5 is in abutment with the bottom of the mounting ring 2 at the top, and the bottom of the protective bag 1 is embedded in the pushing sleeve 5. The bottom of the pushing sleeve 5 is closed, and the pushing sleeve 5 is provided with a pushing rod 6 at the bottom.

[0033] The push sleeve 5 and the push rod 6 of the embodiment are made of hard material, the push sleeve 5 is hollow, the hollow push sleeve 5 can accommodate the protection bag 1, prevent the protection bag 1 from being squeezed when force is applied, and further prevent the tumor from being squeezed. When in use, the medical staff can hold the push rod 6, the mounting ring 2 abuts against the top of the push sleeve 5, and the mounting ring 2 and the protection bag 1 are sent into the vagina of the patient as a whole by moving the push rod 6, so that the operation is convenient.

[0034] As shown in Figures 1-3 In some embodiments of the utility model, the top of the push sleeve 5 is provided with a limiting lug 7, the bottom of the mounting ring 2 is provided with a limiting clamping groove 8, and the limiting lug 7 is embedded in the limiting clamping groove 8. The utility model sets the limiting lug 7 and the limiting clamping groove 8, the limiting lug 7 is embedded in the limiting clamping groove 8 when in use, so that the risk of the mounting ring 2 sliding along the radial direction of the push sleeve 5 can be reduced during the pushing process, and the use process is more stable.

[0035] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and for those skilled in the art, apparently, the application is not limited to the details of the above exemplary embodiments, and the application can be realized in other specific forms without departing from the spirit or basic characteristics of the application.

[0036] Therefore, from any point of view, the embodiment should be regarded as exemplary and non-limiting, the scope of the application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the application. Any reference signs in the claims should not be regarded as limiting the claims. The utility model can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
