Abstract
The utility model discloses a medical device and specifically relates to a miniature radioactive source implantation device. The miniature radioactive source implantation device comprises an implantation bin, a radioactive source storage bin, a hollow needle, a guide block and a push pin, and is characterized in that a reset traction rope is arranged between the push pin and the guide block; and two storage cavities communicated with the implantation bin are arranged in the radioactive source storage bin, and a baffle sheet is arranged at the lower end of one of the storage bins. The miniature radioactive source implantation device has the advantages of reasonable structural design, convenience in use, easiness in operation and large storage quantity of miniature radioactive particles.
Description
Technical field
The utility model discloses a kind of miniature radiation source implantation equipment, belong to technical field of medical instruments.
Background technology
Radiotherapy is the important local therapeutic approaches of malignant tumor.It is to adopt special equipment to insert the canceration position radioactive grain, and the lasting decay through radioactive grain reaches therapeutic effect.The radioactive grain implantation instrument that in the past adopted, the stored number of radioactive grain is few, generally can only store the 20-50 grain, need repeatedly implant could satisfy treat required; Pushing pin in the operating process is not easy resilience, and operation is trouble comparatively; In addition, present radioactive grain implantation device volume is bigger, uses dumb.
The utility model content
For overcoming the prior art deficiency, this utility model provides a kind of advantages of small volume, and is easy to use, the miniature radiation property granule implantation device that memory space is big.
For realizing above-mentioned technical purpose; This utility model is to adopt following technical scheme to realize: a kind of miniature radiation source implantation equipment; Above the implantation storehouse of hollow, be provided with the radioactive source storage silo; Radioactive source storage silo upper end is provided with the capping of band propelling spring, implants the storehouse front end and is provided with hollow needle, and tail end is provided with guiding block, pushes pin; It is characterized in that: push pin and guiding block between be provided with the pull rope that resets; Be provided with two storage chambeies that communicate with the implantation storehouse in the radioactive source storage silo, wherein lower end, a storage chamber is provided with catch, and the catch outer end extends to implants the outside, storehouse, and limits through a bayonet socket, and catch is provided with back-moving spring.
The beneficial effect of this utility model is: be provided with the pull rope that resets owing to push pin, push pin and can automatically reset, need not artificial pulled backwards; Be provided with two storage chambeies in the radioactive source storage silo, memory space is big, after the radioactive grain of a storage intracavity uses up, can catch be extracted out, so that use the radioactive grain of another storage intracavity.Its reasonable in design, easy to use, operation easily, and miniature radiation property granule memory space is big.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the structural representation at catch place.
Among the figure, 1, implant the storehouse, 2, guiding block, 3, push pin, 4, the pull rope that resets, 5, the radioactive source storage silo, 6, capping, 7, propelling spring, 8, radioactive grain, 9, catch, 10, holder, 11, hollow needle, 12, bayonet socket, 13, back-moving spring.
The specific embodiment
With reference to accompanying drawing 1, shown in 2, a kind of miniature radiation source implantation equipment is provided with radioactive source storage silo 5 above the implantation storehouse 1 of hollow, and radioactive source storage silo 5 upper ends are provided with the capping 6 of band propelling spring 7; Implant storehouse 1 front end and be connected with hollow needle 11 through holder 10, tail end is provided with guiding block 2 and pushes pin 3; It is characterized in that: push pin 3 and guiding block 2 between be provided with the pull rope 4 that resets; Be provided with two storage chambeies that communicate with implantation storehouse 1 in the radioactive source storage silo 5; The storage intracavity is placed with radioactive grain 8, and wherein lower end, a storage chamber is provided with catch 9, and catch 9 outer ends extend to implants 1 outside, storehouse; And limit through a bayonet socket 12, catch 9 is provided with back-moving spring 13; Catch 9 is under the qualification effect of bayonet socket 12; Can storage chamber in the radioactive source storage silo 5 of its top and implantation storehouse 1 be separated; After the radioactive grain 8 of another storage intracavity runs out of; Bayonet socket 12 is rotated to a side, and catch 9 outwards moves under the effect of back-moving spring, and then makes the radioactive grain 8 of top get into implantation storehouse 1.
