Description
Technical field
The present invention relates to medical instruments field, belong to the front subject that machinery intersects with medical science, particularly relate to a kind of plesioradiotherapy equipment.
Background technology
In the treatment of cancer, except operation and chemotherapy, radiotherapy is also an important means.Radiotherapy is the roentgenization tumor with various different-energy, to suppress and to kill a kind of Therapeutic Method of cancerous cell, can be divided into telecurie irradiation and irradiation at short distance according to roentgenization mode.Telecurie irradiation and extracorporeal irradiation are, by roentgenotherapia machine etc., ray focusing is carried out short irradiation to body surface or in-vivo tumour position, to play the effect of killing tumor cell outside human body.Irradiation at short distance is that the radioactive source particle of high dose rate forever or is temporarily imported tumor cancer site by external device, thus kills and wounds tumor cell, and irradiation at short distance completes mainly through afterloading unit or acupuncture mechanism.
Plesioradiotherapy compares teleradiotherapy following several large benefit: 1) closely high dose rate ray is gathered in tumor locus by radiant, and normal adjacent tissue is subject to very little dose irradiation, thus protection normal structure, reduce the side effect of irradiating; 2) can irradiate tumor from multi-faceted, thus improve the effect to tumor-killing; 3) treatment time is short, and patient can go to a doctor at any time.
Plesioradiotherapy capital equipment is afterloader, afterloading unit by intracavity, pipe, in interpolation, art, the means such as to apply ointment or plaster insert the mini-radioactive resource of high dose cancerous cell in human body.The radioactive source of high dose rate is fixed by welding in and drives steel wire end, under inner conduit and external treatment conduit guide, arrive oncotherapy point.The process of afterloading unit work is successfully derived by radioactive source, then under the effect of dividing head, selects different treatment passages.Used the situation of different manufacturers afterloading unit by various big hospital, recognize that the afterloading unit of almost each producer has different problems in actual use, treatment channel selecting centering is forbidden, and radioactive source transmission has some setbacks.
Summary of the invention
The present invention provides a kind of structure simple high dose rate multichannel afterloader indexing head mechanism for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of high dose rate multichannel afterloader indexing head mechanism, comprise shell, vertical installing plate is connected with in described shell, the rear of described vertical installing plate is provided with index dial in parallel, described index dial is by step motor drive, and described motor is fixedly mounted on described vertical installing plate; Described index dial is connected with S type conduit, described index dial is stretched out in the outlet of described S type conduit, and relative with the entrance of connecting duct, many described connecting ducts are fixed on described vertical installing plate, and the outlet of described connecting duct is connected with external treatment catheter interface.
Described vertical installing plate is fixed with electric magnet, described electric magnet is provided with the push-pull bar be slidably connected with it; Described index dial is provided with the locating hole with described push-pull bar adaptation.
The advantage that the present invention has and good effect are: motor is arranged on vertical installing plate front, make internal structure more reasonable, can realize passage in whole distribution circumferentially, conveniently treat use.By arranging uniform locating hole on index dial, coordinating the push-pull bar of solenoid actuated to carry out spacing, thus achieving the accurate location to index dial.Structure of the present invention is simple, easily manufactured, easy care.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of index dial of the present invention and S type conduit;
Fig. 3 is the side view of Fig. 2.
In figure: 1, shell, 2, index dial, 21, locating hole, 3, S type conduit, 4, push-pull bar, 5, vertically installing plate, 6, electric magnet, 7, connecting duct, 8, motor, 9, treatment catheter interface.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 3, a kind of high dose rate multichannel afterloader indexing head mechanism, comprise shell 1, vertical installing plate 5 is connected with in shell 1, the rear of vertical installing plate 5 is provided with index dial 2 in parallel, index dial 2 is driven by motor 8, and motor 8 is fixedly mounted on vertical installing plate 5.Index dial 2 is connected with S type conduit 3, index dial 2 is stretched out in the outlet of S type conduit 3, and it is relative with the entrance of connecting duct 7, many connecting ducts 7 are fixed on vertical installing plate 5, the outlet of connecting duct 7 is connected with external treatment catheter interface 9, vertical installing plate 5 is fixed with electric magnet 6, electric magnet 6 is provided with the push-pull bar 4 be slidably connected with it, index dial 2 is provided with the locating hole 21 with push-pull bar 4 adaptation.
Operation principle of the present invention:
During afterloading unit work, motor accepts instruction, and electric magnet obtains electric simultaneously, push-pull bar is regained, depart from locating hole, now step motor drive index dial rotates a set angle, makes S type winding pipe exit aim at connecting duct entrance on vertical installing plate, form special modality, now electric magnet power-off, push-pull bar end extend out in locating hole, and index dial is locked, can not rotate, radioactive source imports setting oncotherapy point by established passage and treats.A single point has been treated rear radioactive source and has been retracted in safety can by steel wire by drive motors, then repeats the treatment that above-mentioned steps proceeds next point of care, until complete the treatment of all point of care.
Above-mentioned S type duct entry is connected with radioactive source safety can, and the centres of S type duct entry end face center and index dial, rotate smoothly to realize S type conduit, can not twist.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protects, can also make a lot of form, these all belong within protection scope of the present invention.
