Resumen:
Un centro de investigación italiano ha desarrollado una pieza de mano con aplicador para sutura inducida por láser de tejidos biológicos, donde la transmisión de la radiación láser en la superficie a irradiar se realiza mediante fibras ópticas. Esta pieza es un dispositivo de diseño adaptado que se utiliza por cirujanos oculares con el microscopio. La tecnología está patentada. Actualmente la tecnología de desarrollo, los materiales y el coste industrial de la pieza de mano ya han sido analizados, pero la fase de desarrollo del prototipo no ha sido implementada todavía. El centro de investigación busca empresas interesadas en desarrollar el prototipo e industrializar la tecnología mediante acuerdos de licencia.

Tittle:
Hand piece for laser induced-suture of the cornea
Summary:
An Italian Research Centre has developed an applicator hand piece for laser-induced suture of biological tissues, in which the transmission of the laser radiation on the surface to be irradiated is realized by means of optical fibers. This hand piece is a suitably designed device to be operated by the eye surgeon under the operating microscope. The Italian centre looks for companies interested in the prototypical development and industrialisation of the technology through licence agreements.
Description:
The group of research is committed in physics area and has developed plenty of researches with market applications in several fields: laser sources for biomedical devices, devices for environmental monitoring processes, aerospace applications. Concerning the biomedical applications the Research Centre has a dedicated optoelectronics laboratory.
The laser-induced corneal suturing technique has been proposed in ophthalmic surgery. The laser activation produces, at a microscopic level, the interdigitating of collagen fibrils which realizes, at a macroscopic level, the suturing and sealing of corneal wound. One of the main technical problems that have so far limited the diffusion of this technique in the clinical setting is the control of the local temperature, which depends on the laser irradiation intensity (Watts/cm2) on the corneal surface.
The proposed technology is a device designed to support the laser-induced suturing of biological tissues, suitably fitting the needs of ophthalmic surgery.
The technology consists of an applicator hand piece, whose handle has a terminal section made of a material transparent to laser radiation, in which the end tips of one or more optical fibers are arranged to irradiate wound. The terminal section, made of a transparent, biocompatible and sterilisable plastic, has the purpose of pre-establishing the distance between the fibers and the surface to be irradiated, so as to keep constant the laser intensity on the surface of tissue during suturing operations.
The groups has patented the technology and wishes to have industrial partners to prototype and industrialise it, since the technology has not yet being realised. The proposed agreements are primarily licence agreements. Other form of cooperation will eventually be evaluated.
Advantages and Innovations:
The laser-induced suturing, the irradiation is typically performed with an optical fiber manually operated by the surgeon and maintained at a distance of some millimetres from the corneal surface, but without certainty of the actual distance. The invention solves this problem and allows to fix the specific power per unit of surface on the irradiation area.
Furthermore, the present technology can be realised with very low-cost plastic materials. The researchers estimated the realization costs and will share it to partners interested in cooperation agreements.
Stage of Development:
Proposal under development
IPs:
Patents granted
CommeR Statunts Regarding IPR Status:
The technology has been patented in Italy and the patent has also been extended (PCT).
