Abstract

The utility model relates to medical apparatus, in particular to a vision-fixation device for ocular tumor radiation treatment. The vision-fixation device for the ocular tumor radiation treatment comprises a face molding fixing mask. The mask is provided with an eyeshade. A plurality of light-emitting diode (LED) point light sources for human eyes to gaze are arranged in the eyeshade. The point light sources are in communicating connection with a light source controlling device which achieves independent control of each LED point light source. The mask provides the required body fixation for the radiation treatment, and vision-fixation targets of different directions for ophthalmology tumor patients. The LED can not only control the directions, but also conveniently utilize switches to control lamps of different directions to prevent eyeballs from moving.

Description

Be used for the radiocurable solid view apparatus of ocular tumor

Technical field

This utility model relates to medical apparatus and instruments, is specifically related to a kind of radiocurable solid view apparatus of ocular tumor that is used for.

Background technology

Because lymphoma cell is to the high susceptibility of lonizing radiation, radiotherapy is the first-selected therapeutic modality of Intraocular lymphoma treatment; Radiocurable office control rate is on 95%.Because the spherical rotatable characteristic of eyes, the maximum challenge of Intraocular lymphoma radiotherapy is the fixing of eyes.Accurately fixing of accurate radiotherapy requirement eyes guarantees can not make because of the rotation of eyeball the treatment target area to move, and causes tumor region to break away from the radiotherapy open country, thereby causes the radiotherapy failure of tumor.

The anesthesia that at present the existing eyes fixture of radiotherapy has behind vacuum suction system, the eyeball or eyeball is other and through patient initiatively the fixation point light source fix.Vacuum suction system utilizes vacuum equipment that eyeball absorption is fixing, and its shortcoming is suitable uncomfortable of patient, and possibly cause damage to the leading portion of patient's eye.The local anesthesia meeting causes patient's discomfort, causes eyeball at eye frame bias internal, and possibly repeat anesthesia.Therefore, noninvasive, repeatably luminous point fixedly is feasible, a reliable selection.

Present active point source fixture is mainly used in the stereotactic irradiation of ocular tumor, and external light source can be fixed on the metal fixed frame of stereotactic irradiation; But metal framework can not carry out nuclear magnetic resonance, NMR (MR) imaging.Ocular tumor patient's conventional external exposure radiotherapy is fixed with the thermoplastic face shield usually, and the thermoplastic face shield can block eyes, can't watch external light source, makes troubles to treatment.

Summary of the invention

To the deficiency that prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, and that realizes patient's noinvasive, can repeat and effectively reliably look admittedly is used for the radiocurable solid view apparatus of ocular tumor.

For realizing above-mentioned purpose; This utility model provides following technical scheme: a kind of radiocurable solid view apparatus of ocular tumor that is used for; Include face's plastotype fixed visors; Face shield is provided with eyeshield, is provided with the point source of some confession people eye fixations in the eyeshield, and said point source communication link is connected to the light source controller of realizing that each point source is independently controlled.

Adopt technique scheme, on the face shield of traditional fixing human position, eyeshield is set, light, provide patient to look target admittedly, thereby prevent that patient's eyeball from rotating, and plays one and regard usefulness admittedly as through a certain point source on the control eyeshield; This device is for patient provides noninvasive, repeatably luminous point is fixed; Eyeshield with point source is set on face shield, separates with external light source to be provided with traditional fixed visors and compare, be patient's luminous point target that the patient watches of providing convenience, admittedly look effective, this structural design is simple simultaneously, and is easy to use.

This utility model further is set to: described eyeshield is to be located at face shield to be positioned at the arc on the human body eye correspondence position, and arc is the spherical arc setting that adapts with people's augen towards human body eye one sidewall.

Through adopting technique scheme, eyeshield is provided with simple and convenient, eyeshield cambered surface setting spherical in shape, and then eyeshield all directions and human eye distance is roughly the same, is convenient to human eye and watches point source, searches out and looks target admittedly; Simultaneously, it is roughly the same apart from position of human eye that this is provided with down each point source, avoids switching difference light source, the incompatibility of bringing apart from difference because of point source in the eyeball rotation process.

This utility model further is set to: described light source controller comprises power supply and some gauge taps; Said point source is electrically connected the power supply of light source controller and the independent control that gauge tap is realized point source.

Through adopting technique scheme, through face shield the human body position is fixed, press the gauge tap on the controller, point source is connected luminous, and according to which point light source light-emitting of switching device control, people's eyeball follows light to walk thereupon, regards usefulness admittedly as thereby play one.

This utility model further is set to: described point source is the LED point source.

Through adopting technique scheme, the luminous body of LED is near " point " light source, and Design of Luminaires is comparatively convenient, and LED to have a life-span long; Body is light in a small amount, power consumption little (energy-conservation), and low cost and other advantages, and running voltage is low; Luminous efficiency is high, and emission response time is extremely short, and operating temperature range is wide; Photochromic pure, sound construction (shock resistance, vibration resistance), series of characteristics such as stable and reliable for performance.

Below in conjunction with accompanying drawing this utility model is further described.
