Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary instruments, and in particular to an implant needle fixer. Background Art

[0002] Radiotherapy is a common treatment for cervical cancer patients. Radiotherapy is mainly suitable for patients with advanced cervical cancer or early cervical cancer patients whose general condition is not suitable for surgery. After surgical treatment, pathological examination found high-risk factors. Radiotherapy can be used as an auxiliary means of treatment. For such patients, external irradiation combined with close-range afterloading therapy will allow patients to achieve better results. Today's three-dimensional afterloading therapy is mainly based on implantation needle therapy. Implantation needle therapy is favored by doctors because it can accurately meet the dose distribution of the target area. Implantation needle afterloading generally uses more than 3 implantation needles combined with the main source applicator. When the operating doctor inserts the implantation needle into the vagina, he can only insert it one by one. The operating hospital often needs to fix the already inserted implantation needle with one hand, and then insert more implantation needles into the vagina. When the number of inserted implantation needles is more than 3, it is difficult to fix the implantation needle with one hand. The other hand needs to stuff gauze between the implantation needles in the vagina. Fixing multiple implantation needles with one hand can easily cause the already inserted implantation needles to shift, and it is not convenient to fill gauze inside.

[0003] In view of this, it is urgent to design an implant needle fixer, set up a mounting ring with adjustable caliber, adjust the mounting ring to match the vaginal opening, insert the implant needle into the implant needle limiting hole of the mounting ring, and then stuff gauze into the hollow part of the mounting ring, so that the mounting ring is stably fixed in the vaginal opening, and at the same time, the mounting ring is used to limit the implant needle, so as to more stably fix the implant needle and facilitate the operation.
