Automatic seed implantation device

Abstract

The invention discloses an automatic seed implantation device. The device comprises a mounting base, a push needle, a first driving mechanism, a second driving mechanism, a feeding mechanism and a puncture needle guide mechanism, wherein a first track and a second track are arranged on the mounting base side by side; a push needle mounting seat is arranged on the first track; a puncture needle guide mechanism mounting seat is arranged on the second track; the push needle and the puncture needle guide mechanism are arranged on the push needle mounting seat and the puncture needle guide mechanism mounting seat; the push needle and the puncture needle guide mechanism are driven to move through the first driving mechanism and the second driving mechanism; the puncture needle guide mechanism comprises a driving assembly and a clamping assembly; the driving assembly drives the clamping assembly to clamp and loosen; the feeding mechanism is arranged at one end of the mounting base, and seedsin the feeding mechanism are pushed out through a push needle; and an external mechanical interface is arranged on the mounting base and is used for controlling the whole movement of the seed implanter. Seed implantation can be automatically executed by a machine, and ionizing radiation and implantation deviation of doctors in an operation are avoided.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an automatic particle implanter. Background technique [0002] At present, radioactive substances are widely used in scientific research, laboratories, production, medical applications, etc., especially as medicines, and have been widely used in clinical applications at home and abroad. Implantation of radioactive seeds to treat malignant tumors is a minimally invasive treatment method, which belongs to a type of brachytherapy. It has the advantages of simple operation and good therapeutic effect, and its clinical application has broad prospects. [0003] The radioactive material is implanted into the human body through the particle implanter. The front end of the particle implanter is connected with a puncture needle, and the rear end is connected with a push needle. During the operation, generally a plurality of puncture needles are first punctured into the pati...

Problems solved by technology

[0005] In order to overcome the problem that the manual and semi-automatic particle implanters in the prior art require high professional quality of doctors, the present invention provides an automatic particle implanter, which can replace the doctor to carry out the operation of particle implantation, and solve the problem of the doctor's operation during the operation. There will be implantation deviation. If radioactive seeds are implanted, they will be exposed to ionizing radiation of radioactive particles
