Description
What the present invention relates to is the method and apparatus that tumor in the human body is carried out radiotherapy and microwave heat therapeutic integrated therapeutic.
Put, thermotherapy in conjunction be the treatment tumor effective means.Past radiotherapy and thermotherapy are independently carried out separately.Put, the specification and the standard disunity of heat treatment unit, patient is accepting to put, is generally needing in the process of thermotherapy twice preparation or operation.This method complicated operation, time-consuming, the patient time is long.And in patent 87104821, a described just radiotherapy apparatus.Its drive part has a spiral sheave, and has only dummy pipe, and the electromagnetism director switch is not set.This equipment can not carry out thermotherapy, also can't combine with heat treatment unit, therefore can not solve the defective of carrying out two operations to patient.
The objective of the invention is to: realization is put, the incorporate Therapeutic Method of thermotherapy.And form by afterloading unit and heat therapy machine are integrated a cover brand-new put, thermotherapy source uniform specification, the type of drive unanimity, new tumor-treating machine is realized the method.
The present invention relates to the putting of inside of human body, thermotherapy method, the method is to realize like this, patient is put, before the thermotherapy, earlier a plastic tube is inserted the body foci position, use driving device then, radioactive source or thermotherapy source are successively entered the body foci position by plastic tube, can in same plastic tube, carry out thermotherapy within a certain period of time according to doctor's requirement before radiotherapy or after the radiotherapy.
Radioactive source is located at the front end of steel cable, and the physical dimension in thermotherapy source is a coaxial cable with to put the body source similar, and its radiant section is at the front end of cable, and is provided with the temperature control original paper.
The drive part in radioactive source and thermotherapy source is two identical autonomous systems of structure.Put in order to make, the thermotherapy source is used, and adopted ring groove wheel and front and back conduit mechanism, this device mainly is made up of ring groove wheel, belt guide pulley, belt, source dummy pipe, source rear tube, several parts of motor.Two provenances are respectively in the groove of separately ring groove wheel, by the transmission of belt pressing friction.The source can enter ring groove wheel by dummy pipe, comes out from rear tube then.
For definite position, the present invention that can determine radiation source movements is provided with out the source Photoelectric Detection at the front end of source electromagnetism director switch, on the dummy pipe of source, be provided with back source electrode limit Photoelectric Detection, afterbody at the source rear tube, be provided with radioactive source return Photoelectric Detection and on the motor rear axle, be provided with photoelectric encoder.
For the guiding in radioactive source and thermotherapy source, be provided with source guiding electromagnetic switch at the front end of safety can.
For preventing that radioactive source from withdrawing from safety can, be provided with spacer pin at the end of rear tube.
In order to adapt to the multichannel therapeutic modality of single source, this equipment is provided with the multichannel lock collar, and z shape conduit.Z shape conduit connects with a motor, selects different treatment passages by the rotation of commander's motor.
The design in thermotherapy source is to get one section coaxial cable, front end antenna for radiating microwave is set, and places the micro semiconductor temperature sensing device on antenna, with high strength enamelled wire the signal of temperature sensing device is drawn with computer control circuit to be connected, and reaches the purpose of temperature control.
The characteristics and the advantage of method and apparatus of the present invention are:
1, put, thermotherapy can be once with the machine treatment, put, thermotherapy need not distinguish intubate, alleviates patient's misery, the therapeutic efficiency height.
2, safety detection is perfect, the reliability height.
3, source in-place precision is good.
4, the thermotherapy temperature control is reliable.
Example by tumor equipment therefor and method in radioactive source and the thermotherapy source treatment human body is described with reference to the accompanying drawings.
In the accompanying drawing: Fig. 1 is that pipeline transmits overall schematic.
Fig. 2 is a source frictional drive perspective view.
Fig. 3 is the safety can perspective view.
Fig. 4 is an electromagnetism director switch cutaway view.
Fig. 5 is that source channels is selected perspective view.
Fig. 6 is the driving mechanism sketch map.
Fig. 7 is that the thermotherapy source connects sketch map.
The driving mechanism in the driving mechanism of radioactive source and thermotherapy source is independently mechanism's (see figure 6) of same difference
Circular disk 1 is placed on the motor 25, and photoelectric encoder 26 joins with the rear axle of motor 25.Photoelectric encoder 26 is used for detecting the anglec of rotation of motor 25.The lead in the steel wire of radioactive source or thermotherapy source is placed in the cannelure 27, and belt 4 compresses it, drives the source frictional drive.The source sends out by dummy pipe 5 or 7, and dummy pipe 5 or 7 connects with safety can 9, and regain by rear tube 6 or 8 in the source.
Source electromagnetism director switch 12 is the guiding radioactive source or the discrepancy of thermotherapy in order to decision.And be used for when finding the radioactive source abnormal operation, playing braking action, prevent the derivation of radiating.Go out the front end that source photoelectric source survey 24 is placed on source electromagnetism director switch 12, in order to the initial starting point of determining that the source emits, go out the both sides that source electrode limit Photoelectric Detection 18 is placed on the radioactive source rear tube, be used for determining that radioactive source goes out the extreme position in source, when radioactive source arrives this position, still continue to emit, then electromagnetism director switch 12 actions stop the continuation in source to be derived.
Radioactive source return Photoelectric Detection 19 is placed on the radioactive source rear tube tail end, is used for detecting the center that radioactive source is recovered to safety can 9.After preventing that radioactive source from getting back to safety can 9 centers, still continue to reclaim, be provided with spacer pin 20 at the end of rear tube 6.
The thermotherapy source is returned source electrode limit Photoelectric Detection 17 and is arranged on the thermotherapy source rear tube 8, is used for preventing that thermotherapy source Hui Yuan from surpassing extreme position.
In order to prevent the radiation of ray, be provided with radiation protection jar 9, radioactive source dummy pipe 5 and thermotherapy dummy pipe 7 therefrom pass, and connect with electromagnetism director switch 12, and two pipelines are configured to the same z shape of geometry at the jar center.
Get one section coaxial cable, about 0.1m is respectively reserved at two ends.All the other leads are peelled off protective layer and outer conductor; expose dielectric layer; enclose the layer of polyethylene thin film with sintering process then; behind absolute alcohol cleansing medium layer; plate a bed thickness and be tens microns silverskin; long that segment protect layer and the outer conductor of the about 0.1m of the arbitrary end of coaxial cable peelled off; expose dielectric layer; again this part is divided into two sections, long 1/4 wavelength in rear end, the about 3cm of front end; redundance cuts off; the dielectric layer of front end 3cm section peelled off exposes inner wire, this part inner wire by counterclockwise spiral on 1/4 wavelength period, after antenna is carried out; with on antenna, enclosing the layer of polyethylene thin film around connection; place a micro semiconductor critesistor at the antenna middle part then, do temperature detector, semiconductor leads is connected with high strength enamelled wire; the latter; draw along the coaxial cable spiral, enclose the layer of polyethylene thin film with sintering process at last on coaxial cable and antenna total length, above-mentioned extraordinary mixed type microwave antenna is used for thermotherapy.
The design of this equipment is specially adapted to the putting of tumor in the human body, thermotherapy integrated therapeutic.
