Spine tumor radiotherapy and centrum forming integrated device

Abstract

The invention discloses a spinal tumor radiotherapy and centrum forming integrated device. The integrated device comprises an implantable bone positioning sleeve, a radiotherapy push rod, an expansion balloon and a bone cement imbedding push rod, wherein positioning scales are arranged on the outer wall of the implantable bone positioning sleeve; the radiotherapy push rod is inserted into the implantable bone positioning sleeve in a pluggable mode, radiotherapy particles exposed out of the lower end of the implantable bone positioning sleeve are arranged at the lower end of the radiotherapy push rod, and the expansion balloon sleeves the lower end of the radiotherapy push rod; a liquid / gas inlet / outlet channel is formed in the radiotherapy push rod; and a lower opening of the liquid / gas inlet / outlet channel communicates with the expansion balloon, and an upper opening is exposed out of the upper end of the implantable bone positioning sleeve. The integrated device has the effects that after the implantable bone positioning sleeve is inserted into the center of a spinal tumor region of a patient and positioned, the radiotherapy particles are basically located at the center of the spinal tumor region of the patient and do not drift, so that the radiotherapy effect of the spinal tumor region of the patient is good; and bone cement can be injected into the implantable bone positioning sleeve conveniently, and the positioning sleeve is dual-purpose and convenient to use, so that the overall operation is time-saving and labor-saving, and the use effect is excellent.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an integrated device for spinal tumor radiotherapy and vertebral body shaping. Background technique [0002] In the orthopedic departments of major hospitals, for patients with spinal tumors, such as patients with bone metastases and vertebral body metastases, it is usually necessary to use a special opener to open a surgical channel to the center of the patient's spinal tumor, and then use radiotherapy equipment to treat radiotherapy. The particles are sent to the center of the patient's spinal tumor through the corresponding surgical channel to perform short-distance and rapid radiotherapy on the tumor tissue to kill the tumor cells, and then the radiotherapy equipment is used again to deliver the radiotherapy particles from the center of the patient's spinal tumor through the corresponding surgical channel. Take it out, and finally use the bone grafting instrument to ...

Problems solved by technology

[0004] Specifically, on the one hand, when using radiotherapy equipment to send radiotherapy particles to the center of the patient's spinal tumor site through the corresponding surgical channel to perform brachytherapy and rapid radiotherapy on the tumor tissue, during the corresponding radiotherapy process, the radiotherapy particles used will exist. Due to drift and other conditions, it will not always be in the center of the tumor site, and the tumor tissue farther away from the radiotherapy particles will not receive better radiotherapy, making the radiotherapy effect poor. On the other hand, after the radiotherapy particles used are used up, When it is not at the center of the tumor site, it will be laborious and difficult to take out, and when the radiotherapy particles are sent to the center of the patient's spinal tumor site through the corresponding surgical channel to perform short-distance and rapid radiotherapy on the tumor tissue, the patient's spinal tumor The tissue is soft and elastic, so that it will elastically surround the corresponding radiotherapy particles. For the spinal tumor tissue that is far away from the corresponding radiotherapy particles, it will also not be able to receive better radiotherapy. , and then inject bone cement to the center of the tumor site, two sets of unrelated operating tools are required, so that the center of the tumor site needs to be positioned twice, which makes the operation time-consuming and laborious, increases the operation time, and increases the workload of medical staff volume and increase patient suffering
