Description
Technical field
The utility model belongs to gynaecology's radiotherapy apparatus technical field, is to be related to a kind of vagina applicating device more specifically.
Background technique
In the treatment of gynecologic malignant tumor, 70%-80% patient needs the process of experience radiotherapy over the course for the treatment of,
Wherein short distance after-loading therapy is very important link in radiotherapy.Although after-loading therapy develops from two-dimensional treatment mode
The three-dimensional after-loading therapy guided to image solves many treatment difficult points such as eccentricity tumour, huge tumor, palace side recurrent tumor
Deng.But there are still segmental defects in current therapeutic process.
In cellular level the study found that the radiation exposure of low dosage can lead to the cell of expression tumor stem cell marker
Ratio is significantly raised, and shows radiotherapy resistance.Prompt tumor by local exposure dose uneven distribution be after leading to radiotherapy not
The reason of control and recurrence.
By the clinical analysis discovery of the cervical cancer patient of many cases recurrence after radiotherapy, different parts recurrent tumor is to radiotherapy
There are biggish differences for sensibility, therefore pay attention to therapeutic choice and the implementation of individuation, improve and ensure the radiotherapy of tumor target
Dosage is the important link for improving patient's prognosis.
Firstly, applicating device used at present is the standardization column applicating device of a few money different-diameters, applied using standardized
The treatment of source device, mode excessively idealize, and different parts and tumour of different shapes can only select similar target region shape, result
It is bound to cause Partial tumors to miss the target, or sacrifices excessive normal tissue to guarantee the radioactive dose of tumor tissues, cause
Radiotheraphy secondary reaction is significantly raised.Secondly, the transplanting needle of doctor's merging due to lacking fixed device, can lead to portion because of the contraction of muscle
Divide and changes direction；Relying only on the empirical judgement inserting needle direction of naked eyes will appear the uneven of cloth source；The object in addition, part vagina swells,
Since the exposure of vaginal speculum is limited, leads to swollen object exposure not exclusively, influence the merging of applicating device.If being controlled through unarmed transplanting
It treats, since transplanting needle direction interlocks, increases physics teacher and complete the difficulty for the treatment of plan and technician's operation, and treat pipeline
It is connected inconsistent with the setting of plan, and can greatly influences therapeutic effect.

It please refers to shown in Fig. 1 and Fig. 2, as a kind of specific embodiment of vagina applicating device provided by the utility model,
The transplanting needle 6 is equipped with scale.Lesion is treated, in order to avoid injuring normal tissue and reaching highest treatment effect
Fruit, transplanting needle 6 need doctor to be accurately positioned into intralesional depth, effect that is too deep or shallowly will affect treatment excessively
Fruit, transplanting quality are influenced very greatly, therefore, have great requirement to the operation level of doctor, still by operator's qualification
In actual operation, everyone operation level is not identical, therefore will affect the effect for the treatment of.The applicating device of the application leads to
It crosses and sets scale in 6 subscript of transplanting needle, the design of applicating device ontology 1 is prepared using 3D printing technique, the distance of each transplanting holes 3
The distance that lesion is reached with the end for corresponding to transplanting holes 3 on the second curved surface 2 is tightly designed by imaging with draughtsmanship, therefore
Treatment when, the depth that transplanting needle 6 is inserted into transplanting holes 3 be it is pre-designed, therefore, by being designed on transplanting needle 6
Scale, so that each doctor can be by the identification to scale, scheduled transplanting position can be reached by so that every root cutting is planted needle 6
It sets, reaches therapeutic effect most preferably, so that treatment is not limited by doctor's level, and therapeutic effect is best.Certainly, may be used
Scale is set not plant the whole mark of needle 6 to every root cutting, every root cutting plant needle 6 is corresponding with corresponding transplanting holes 3, and therefore, every root cutting is planted
Therefore the insertion depth of needle 6 in the position into depth of transplanting needle 6 in advance it was determined that, can only be marked, can be
Scale mark when transplanting needle 6 is inserted into transplanting holes 3, stops insertion when label reaches 3 one end of transplanting holes into needle end face, such as
This operation, equally can control the insertion depth of transplanting needle 3, more convenient, quick, improve efficiency.
The clinical use of above-mentioned individuation vagina applicating device succinctly facilitates, and significant effect can break through current after-loading therapy
Applicating device single variety, the limitation for lacking individuation greatly improve radiotherapy quality, and will not increase overweight economy to patient
Burden, so certain economic benefit can be brought to hospital.
Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
Explanation be merely used to help understand the method and its core concept of the utility model.It should be pointed out that for the art
For those of ordinary skill, without departing from the principle of this utility model, several change can also be carried out to the utility model
Into and modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
