Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an external fixation device for gynecological post-implantation radiotherapy implantation needles. Background Art

[0002] Gynecological radiotherapy is a common method for gynecological treatment of malignant tumors. It uses rays of different energies to irradiate tumors, thereby inhibiting and killing cancer cells. Gynecological radiotherapy indications include various gynecological malignancies such as cervical cancer, vaginal cancer, endometrial cancer and ovarian cancer. According to the purpose of treatment, gynecological radiotherapy can be divided into adjuvant radiotherapy, radical radiotherapy and palliative radiotherapy. Radical treatment is suitable for patients with advanced gynecological malignancies or those who cannot tolerate surgery. Adjuvant radiotherapy is used for supplementary treatment after malignant tumor surgery. Palliative radiotherapy is suitable for patients with recurrence after surgery and radiotherapy and chemotherapy.

[0003] Gynecological radiotherapy can be divided into external beam radiotherapy, afterloading radiotherapy or a combination of the two, depending on the method of radiotherapy. External beam radiotherapy is the radiation generated by the radioactive source entering the body from outside the body, while afterloading radiotherapy is the placement of the radioactive source into the tumor location in the human body for irradiation. Afterloading radiotherapy requires the use of CT-guided intracavitary combined interstitial afterloading technology. The radioactive source is directly delivered to the deep part of the tumor through the implant needle for radiotherapy. The implant needle is the irradiation channel of afterloading radiotherapy, and then the radiation source is connected for treatment according to the radiotherapy plan. Afterloading radiotherapy has a high radiation dose to the center of the tumor, protects the normal organs and tissues around the tumor, and has few side effects. Therefore, it has an irreplaceable position in the radical radiotherapy of gynecological tumors.

[0004] Since each implant needle head has a certain radiation radius during radiotherapy, in order to achieve the best treatment effect and kill tumor cells as much as possible, the doctor needs to determine the angle, depth and insertion point of the implant needle according to the imaging results of the patient's preoperative examination before radiotherapy. Currently, the angle, depth and insertion point of the implant needle are generally determined in advance through 3D printing of the implant needle guide template. However, the 3D printed implant needle guide template is expensive, which increases the burden on patients. In addition, the 3D printed implant needle guide template is strictly determined before insertion and cannot be adjusted according to the actual situation found during the operation, so it often does not necessarily achieve a good treatment effect. Utility Model Content

[0005] The utility model aims to provide a gynecological implant post-loaded radiotherapy implant needle external fixation device to solve the technical problems that the existing 3D printed implant needle guide template is expensive, cannot be adjusted according to the actual situation during the operation, and cannot guarantee the treatment effect.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A gynecological post-implantation radiotherapy implant needle external fixation device comprises a perineum mask, both left and right sides of the perineum mask are provided with adhesive stickers, the left and right sides of the perineum mask are respectively connected with two fixing belts, and the ends of the two fixing belts are correspondingly provided with Velcro;

[0008] A through opening is provided on the perineal cover, a cylindrical body is fixed at the through opening, a cylindrical drug sponge is arranged inside the cylindrical body, a central channel is arranged along the axis of the drug sponge, an orientation cover is arranged at the outer end of the cylindrical body, the orientation cover and the end of the cylindrical body are rotatably matched, a first center hole and a plurality of jacks are arranged on the orientation cover, a rubber plate is arranged at the inner end of the cylindrical body, and a second center hole is arranged on the rubber plate.

[0009] Furthermore, a storage bag is connected to the lower part of the perineum cover, and an opening support strip is arranged at the bag opening of the storage bag.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model can not only fix the implant needle by means of the rubber plate and the orientation cover, but also adjust the angle and depth of insertion according to the intraoperative situation, and during insertion, medicine is applied on the surface of the needle to achieve the therapeutic effect, and the utility model is easy to use.
