Description
Technical field
The invention patent relates to medical instruments fields, belong to the mechanical front subject intersected with medicine radiotherapy field.It is one
Kind is performed the operation for cervical carcinoma afterloading radiotherapy, the surgical guide of adjuvant clinical doctor reasonable Arrangement transplanting needle and applicating device.
Background technique
Afterloading radiotherapy is the important technical reform of gynecologic malignant tumor irradiation at short distance.Afterloading radiotherapy refers to elder generation
Treatment container without radioactive source is placed in therapentic part, radioactive source is sent into treatment container by Computerized remote-control stepper motor and is carried out
Treatment, targeting is stronger, and the damage of normal tissue is smaller, belongs to very promising emerging field.60 years 20th century
For the development of front and back atomic industry, it is capable of providing clinical required radioactive source.The development of automatic technology ensure that the spirit of machine
Quick property and reliability.Afterloading unit has had quite high technical level at present, curative for effect, breaches traditional treatment mode,
New hope is brought to the treatment of malignant tumour.
Afterloading radiotherapy radioactive source accurately can be safely transported to patient position in need for the treatment of carry out radiation control
It treats, when having the advantage that a. is irradiated using the high dose rate of high activity radioactive source, each irradiation time only needs a few minutes to ten
A few minutes can reduce the pain of patient；B. preoperative planning is carried out by treatment planning systems (TPS), is put by individual need adjustment
The dosage distribution for penetrating source, makes tumor tissues be in high dose area and the normal tissue of surrounding is in cold spot area, hence it is evident that improves and puts
Penetrate dosage and normal tissue damage very little；C. have good protective action to medical staff, can farthest avoid by
Radiation exposure；D. uterine cavity and vagina applicating device various shapes, are applicable to kinds of tumors lesion and anatomical structure, adaptability is good
It is good.
Source applicator has played huge effect as the main carriers of afterloading radiotherapy afterwards, performance and quality also close shadow
Therapeutic effect is rung, can distress level and treatment when concerning Case treatment smoothly complete.Based on traditional single channel or threeway
The dosage of road applicating device is planned, due to the limitation of lesions position and applicating device structure, so that dosage field cannot be completely covered sometimes
Target area range.In response to this, form of the applicating device in conjunction with transplanting needle is come into being, and the needle track of transplanting is that dosage planning mentions
Additional resident channel has been supplied, has kept dosage distribution results more accurate, is able to achieve more conformal treatment.But due to target area
In patient body, the difficulty of clinic arrangement transplanting needle and applicating device is larger.
Summary of the invention
The present invention provides one kind to solve technical problem present in well-known technique being capable of the reasonable cloth of adjuvant clinical doctor
Set the surgical guide of transplanting needle and applicating device.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of be used for cervical carcinoma
The surgical guide of afterloading radiotherapy is equipped with applicating device in the center of the internal base plate including the internal base plate coincideing with cervix opening
Sets of holes are equipped with transplanting needle via hole I around the applicating device sets of holes.
On the basis of above scheme, the present invention has also done following improvement:
In the outside of the internal base plate, suit, which is fixed with, extends out ring flat-plate, and transplanting needle via hole is equipped on ring flat-plate in described extend out
Ⅱ。
