Description
Technical field
This utility model belongs to technical field of medical instruments, particularly to a kind of aciculiform optical dynamic therapy device.
Background technology
The principle of photodynamic therapy (photodynamic therapy, PDT) treatment malignant tumor is: during treatment,
Photosensitizer is injected blood vessel, when it accumulates a certain amount of at lesion, shines with a kind of specific laser
Penetrating pathological changes to be activated by photosensitizer, the photosensitizer of activation discharges substantial amounts of free radical and singlet oxygen, destroys pathological changes
Tissue cellularity, may result in tumor tissue necrosis's atrophy, reaches therapeutic purposes.This therapy be continue operation,
The fast-developing brand-new therapy risen after radiotherapy, chemotherapy and immunization therapy, has specificity high, wound
Little feature, it has also become one of most active research field in world's treatment and prevention of tumour science.But, due to carefully
The restriction to the penetration depth of light of born of the same parents' tissue, the effective interaction depth in PDT light source is difficult to exceed several centimetres.This
It is its advantage, is also its inferior position.It is the disease of shallow structure for target tissue, such as skin, mucosa
The diseases such as superficial tumor, nevus flammeus, macular degeneration, atherosclerosis and psoriasis, light moves
Power treatment can well damage shallow-layer target body, and does not destroy normal structure.But, for deep tumor or
The tumor that tumor body is bigger, directly applies PDT, and light is difficult to go deep into inside tumor and then eliminate tumor.Therefore,
Optical dynamic therapy is had a major impact by the development of light source and guide instrument.As various shape optical fiber appearance more
Conveniently treat variously-shaped pathological changes.But there is frangible easily broken feature in optical fiber, has certain
Unstable factor.And the light source that PDT mainly uses at present is laser instrument, relatively costly.So, according to
Clinical need, optimize illumination parameter, develop certain operations simple, it is easy to use, output is stable and price just
Suitable equipment need to carry out.
Utility model content
Main purpose of the present utility model is to provide a kind of energy deep enough deeper or the aciculiform of bigger inside tumor
Optical dynamic therapy device, it is intended to improve the stability of therapeutic apparatus itself, convenient to operate and reduction cost.
This utility model is achieved in that a kind of aciculiform optical dynamic therapy device, including electroluminescent nook closing member,
It is sheathed on the transparent electrical insulating film of described nook closing member outer surface, and the conductor wire being connected with described nook closing member, institute
Stating nook closing member and include that shank and needle point, described shank and needle point are structure as a whole, described electrical insulating film is coated with completely
Described nook closing member and consistent with described nook closing member shape, described nook closing member is nontransparent rigidity nook closing member.
As optimal technical scheme of the present utility model:
Described electrical insulating film is nontoxic organic ceramic electrical insulating film.
The wall thickness range of described electrical insulating film is 0.01-1mm, in its diametric total thickness is
0.02-2mm, the diameter range of the needle bar position of described nook closing member is 0.01-3mm.
Described needle point is the tapered tip formed of the end by described shank.
Described needle point be chamfered by the end of described shank after the tip that formed.
The outer cover of described electrical insulating film is provided with needle cap.
This utility model uses electroluminescent nook closing member, can be luminous, through transparent electrical insulating film after its energising
Rear large-area irradiation diseased region, for traditional LASER Light Source, electroluminescent material cost is more
Low, and irradiated area relatively LASER Light Source to irradiate motility higher, and can deeply can be shallow；Need not fiber optic conduction light
Line, and use electroluminescent rigidity nook closing member, it being not easily broken and crush, good stability, for oncotherapy
Efficiency and safety are the most useful；And only needing the energising luminescence to treat, relatively with laser as light source
Treatment is more convenient for implementing.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically
Embodiment, only in order to explain this utility model, is not used to limit this utility model.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, and it can be straight
It is connected on another element or is connected on this another element.When an element is referred to as " being connected to " separately
One element, it can be directly to another element or be indirectly connected to this another element.
Also, it should be noted the orientation term such as left and right, upper and lower in this utility model embodiment, only
It is relative concept or with the normal operating condition of product as reference each other, and should not be regarded as that there is limit
Property processed.
Referring to accompanying drawing 1, this utility model provides a kind of aciculiform optical dynamic therapy device, is used for going deep into position relatively
Deep or the inside of bigger tumor, the photosensitizer of its luminous gathering irradiating diseased region is controlled to carry out light power
Treating, this aciculiform optical dynamic therapy device includes the nook closing member 01 made by electroluminescent material, is sheathed on nook closing member 01
The transparent electrical insulating film 02 of outer surface, and the conduction drawn by external power source 03 being connected with nook closing member 01
Line 04, this nook closing member 01 is nontransparent rigidity nook closing member, and it includes shank 011 and needle point 012, shank 011
Being structure as a whole with needle point 012, this electrical insulating film 02 is coated on the outside of nook closing member 01 completely, for guarantor
Protecting nook closing member 01 and isolate nook closing member 01 and tissue, smooth surface and the hardness of electrical insulating film 02 are bigger simultaneously
So that inserting internal, it addition, the shape of electrical insulating film 02 is consistent with the shape of nook closing member 01, especially its
Tip is more sharp-pointed so that inserting inside tumor.Owing to this nook closing member 01 is made by electroluminescent material, it leads to
Can be with Integral luminous after electricity, this light, through irradiating diseased region after electrical insulating film 02, carries out large-area photograph
Penetrate, make the photosensitizer generation optical sensibilization that diseased region is assembled, produce the effect of killing tumor cell, real
Existing therapeutic purposes.In actual therapeutic, the selecting of electroluminescent material is carried out according to the photosensitizer used
Joining, this aciculiform optical dynamic therapy device is disposable product.
This utility model embodiment uses the nook closing member 01 that electroluminescent material makes, luminous through thoroughly after its energising
After bright electrical insulating film 02, large area irradiates diseased region, for traditional LASER Light Source, electroluminescent
Luminescent material cost is lower, and the irradiation motility of irradiated area relatively LASER Light Source is higher；Need not fiber optic conduction light
Line, and use electroluminescent rigidity nook closing member 01, it being not easily broken and crush, good stability, for oncotherapy
Efficiency and safety the most useful；And only need energising luminescence to treat, relatively with laser as light source
Treatment be more convenient for implement.
Further, the electrical insulating film 02 that the present embodiment uses is nontoxic organic ceramic electrical insulating film, environmental protection,
Transparent, to human non-toxic's side effect.It addition, nook closing member 01 selects, mechanical strength is relatively strong, luminous efficiency is higher
