Description

Technical Field

[0001] The utility model relates to the technical field of radioactive particle implanters, in particular to a novel radioactive particle implanter. Background Art

[0002] Bone tumors are tumors that occur in bones or their appendages. They can be benign or malignant. Benign bone tumors are easily cured and have a good prognosis, while malignant bone tumors develop rapidly, have a poor prognosis, and a high mortality rate. Malignant bone tumors are divided into primary and secondary. Malignant tumors from other tissues or organs in the body that metastasize to the bones through the blood circulation and lymphatic system are secondary malignant bone tumors. There is also a type of lesion called tumor-like lesions. The tissue of tumor-like lesions does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to tumors. They are generally more localized and easier to cure. Usually, a new type of radioactive particle implanter is needed to treat bone tumors.

[0003] When the existing radioactive seed implanter is actually used, the radioactive seeds are implanted once, which easily increases the workload of medical staff and is not convenient for continuous implantation.

[0004] After searching the existing patents: a new type of radioactive particle implantation gun (Announcement No.: CN215461386U), the utility model can support the handle through the cooperation of the support and the support plate, the operator does not need to hold the handle, can operate the handle and the main gun body connected to it, which is conducive to the use of the device. In addition, the support plate and the handle are fixed together by bolts in a threaded connection, so that the handle and the support plate are easy to load and unload. The operator can separate the handle and the support plate, and then hold the handle for use, making the use of the device more flexible and conducive to the use of the device.

[0005] Although the above patent achieves the function of supporting the handle, the operator can operate the handle and the main gun body connected to it without holding the handle, which is convenient for the use of the device. In addition, the support plate and the handle are fixed together by bolts in a threaded connection, so that the handle and the support plate can be loaded and unloaded. The operator can separate the handle from the support plate and then hold the handle for use, which makes the use of the device more flexible and convenient. However, when using the new radioactive particle implantation gun, the medical staff can easily cause the puncture needle to deform or bend during operation, which is inconvenient for the medical staff to use.

[0006] Therefore, it is necessary to invent a new type of radioactive particle implanter to solve the above problems. Utility Model Content
