Patent attributes
A medical optical fiber guidewire converter includes a first connector; a second connector; a conversing optical fiber with an overcurrent channel configured to transmit laser light and including a first and second optical fibers and a connecting optical fiber, a diameter of the first optical fiber is greater than that of the second optical fiber, the first optical fiber is connected to the first connector, and the second optical fiber is connected to the second connector; and a heat sink on the conversing optical fiber. The medical optical fiber guidewire converter couples optical fiber guidewires with different core diameters using the connecting optical fiber, thereby ensuring safety and reliability of laser light transmission in the overcurrent channel. The heat sink can absorb laser light overflowing from the conversing optical fiber and dissipate heat therefrom to reduce the temperature of and avoid thermal damage to the conversing optical fiber.
