Abstract
The utility model discloses a photodynamic laser transmission punctiform optical fiber. The photodynamic laser transmission punctiform optical fiber comprises an optical fiber body, and is characterized in that the photodynamic laser transmission punctiform optical fiber is also equipped with flexible bushings, the optical fiber body penetrates the bushings, and the number of the bushings is between 1 and 10. When the photodynamic laser transmission punctiform optical fiber is used, a users pinches the flexible bushings with a hand to bend and deform the bushings, at the same time, the optical fiber body in the flexible bushings is bent to change the transmission shape of the optical fiber body, so that the reflection times of a laser in the optical fiber is increased, the light spot brightness emitted from a convex lens end becomes uniform. When the laser activation irradiation is carried on a photosensitive medicine, because the light spot brightness is uniform, the activation effectiveness in a light spot is same, the phenomena that the dark part treatment effect is poor, the brightness part exceeds a needed power, do not exist, and the treatment effect is improved. Moreover, the photodynamic laser transmission punctiform optical fiber is convenient in operation, and enables the light spot brightness uniformity to be adjusted to an optimum state easily.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of light power Laser Transmission point-like optical fiber for the tumor laser photodynamic therapeutic equipment.
Background technology
Light power is the method for utilizing photosensitizer and laser activation to carry out disease treatment, is mainly used in the treatment of solid malignant, also is used for simultaneously the treatment of some precancerous lesion and benign lesion.
Optical dynamic therapy need to be finished in two steps, at first will give the patient infusion photosensitive drug, then exactly focal zone is carried out laser irradiation.Laser irradiation is finished by the energy transmission optical fibre of releasing light device termination with difference, such as light power Laser Transmission point-like optical fiber, the structure of this point-like optical fiber comprises the optical fiber body, the two ends of optical fiber body are respectively equipped with adapter and lenticule, the lenticule end is provided with convex lens, this external trocar sheath that also is provided with of optical fiber.The light power Laser Transmission point-like optical fiber of this structure, when adapter is connected with laser generator, the hot spot brightness irregularities that the convex lens end-fire goes out, some local brightness is higher, and some local brightness is lower, is concentric-ring pattern and distributes.When photosensitive drug being carried out the laser activation irradiation, because the hot spot brightness disproportionation, it is variant to cause activation to render a service, dark local therapeutic effect is poor, and bright position surpasses power demand, operation inconvenience, be difficult for the brightness uniformity of hot spot is adjusted to optimum state, affect therapeutic effect.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of easy and simple to handle, easily the brightness uniformity of hot spot is adjusted to optimum state, does not affect the light power Laser Transmission point-like optical fiber of therapeutic effect.
The purpose of this utility model is to realize by following technical scheme:
A kind of smooth power Laser Transmission point-like optical fiber comprises the optical fiber body, unlike the prior art be: be provided with and have flexible sleeve pipe, described optical fiber body passes from sleeve pipe.
Described sleeve pipe is 1-10.
During use, hands is pinched coiled casing, make it flexural deformation, optical fiber body in the coiled casing is thereupon crooked simultaneously, change the shape of optical fiber body, make the order of reflection of laser in optical fiber obtain increasing, the hot spot brightness that the convex lens end-fire goes out becomes evenly, when photosensitive drug is carried out the laser activation irradiation, because hot spot brightness is even, activation is renderd a service identical in the hot spot, do not exist dark section therapeutic effect poor, highlights surpasses the phenomenon of power demand, and therapeutic effect is improved, and easy to operate, easily the uniformity of hot spot brightness is adjusted to optimum state.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the equipped sketch map of optical fiber body and sleeve pipe among Fig. 1.
Among the figure, 1. trocar sheath 2. optical fiber bodies 3. sleeve pipes 4. adapters 5. lenticulees 6. convex lenss.
The specific embodiment
Below in conjunction with drawings and Examples this utility model content is further elaborated, but is not to restriction of the present utility model.
Embodiment:
With reference to Fig. 1 Fig. 2, a kind of smooth power Laser Transmission point-like optical fiber, comprise optical fiber body 2, the two ends of optical fiber body 2 are respectively equipped with adapter 4 and lenticule 5, lenticule 5 ends are provided with convex lens 6, optical fiber body 2 also is provided with trocar sheath 1 outward, is provided with to have flexible sleeve pipe 3, and described optical fiber body 2 passes from sleeve pipe 3.
During work, adapter 4 is connected with laser generator, hands is pinched coiled casing 3, make it flexural deformation, optical fiber body 2 in the coiled casing 3 is thereupon crooked simultaneously, change the transmission shape of optical fiber, the order of reflection of laser in optical fiber body 2 increased, the hot spot brightness that goes out from convex lens 6 end-fires becomes even.When photosensitive drug was carried out the laser activation irradiation, because hot spot brightness is even, activation was renderd a service identical in the hot spot, do not exist dark section therapeutic effect poor, highlights surpasses the phenomenon of power demand, and therapeutic effect is improved, and easy to operate, easily the uniformity of hot spot brightness is adjusted to optimum state.
Occur bending and deformation after sleeve pipe 3 is stressed, because sleeve pipe 3 be coiled casing, after the stressed disappearance, sleeve pipe 3 can not restore to the original state and maintain case of bending, thereby makes the optical fiber bodies 2 maintenance case of bendings in the sleeve pipe 3.
For convenient the different parts of optical fiber is adjusted, increase operation convenience, increase the order of reflection of optical fiber inner laser, the hot spot brightness that convex lens 6 end-fires are gone out is more even, do not affect simultaneously the flexibility of optical fiber in transmission direction, different parts at optical fiber body 2 arranges sleeve pipe 3, and sleeve pipe 3 is 1-10, as shown in drawings for the structural representation of two sleeve pipes is set.
Claims (2)
