One end of first optical fibre is connected with medical optical fibre probe, its another end is equipped with a first collimator, and one end of second optical fibre is equipped with a second collimator, said first collimator is fixed in a tubular connecting member, and said second collimator is fixed in a column connecting member. Besides, said invention also provides its working principle and its advantages.
Description
Technical field:
The present invention relates to gauge, relate in particular to the detection optical fiber of diagnosis instrument for medical use, particularly a kind of anti-distortion detection optical fiber that is used for natural fluorscence diagnosis instrument used for diagnosising.
Background technology:
Now use in the technology, the clinical fiber detector of natural fluorscence diagnosis instrument used for diagnosising that generally utilizes comes the human body lesions position, and fiber detector is connected with diagnosis instrument for medical use by optical fiber.In the use, fiber detector needs often change direction, and the diameter of medical optical fiber is less usually, and its opposing is not high around the ability of axial twisting stress, so optical fiber ruptures easily, influences service life.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because the fiber detector of diagnosis instrument for medical use of the prior art is connected with diagnosis instrument for medical use by optical fiber.In the use, fiber detector needs often change direction, and the diameter of medical optical fiber is less usually, and its opposing is not high around the ability of axial twisting stress, so optical fiber ruptures easily, influences service life.
The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind of anti-distortion detection optical fiber that is used for natural fluorscence diagnosis instrument used for diagnosising, the described this anti-distortion detection optical fiber that is used for natural fluorscence diagnosis instrument used for diagnosising is made of at least one first optical fiber and at least one second optical fiber, wherein, one end of described first optical fiber connects a medical optical fiber detecting head, the other end of described first optical fiber is provided with one first collimator, one end of described second optical fiber is provided with one second collimator, described first collimator is fixedly installed in the tubular connection member, described second collimator is fixedly installed in the column connecting elements, the front end of described column connecting elements is arranged in the tube chamber of described tubular connection member, the point diameter of described column connecting elements is less than the internal diameter of described tubular connection member, the front end of the lumen wall of described tubular connection member and described column connecting elements is connected by a ring-type draw-in groove structure, the axial coincidence of described first collimator and second collimator, described tubular connection member and column connecting elements constitute by polytetrafluoroethylmaterial material.
Further, be provided with cyclic groove in the lumen wall of described tubular connection member, the front end circumference of described column connecting elements is provided with a bulge loop, and described bulge loop is arranged in described groove.
Perhaps, be provided with a bulge loop in the lumen wall of described tubular connection member,, the front end circumference of described column connecting elements is provided with cyclic groove, and described bulge loop is arranged in described groove.
Further, the other end of described second optical fiber is connected with a diagnosis instrument for medical use.
Operation principle of the present invention is: the front end of tubular connection member and column connecting elements by ring-type not the groove structure be connected, can be between tubular connection member and the column connecting elements around axially rotation, first collimator can become collimated light to the light beam of dispersing in the optical fiber, second collimator is coupled to the collimated light from first collimator in second optical fiber with very little loss, when keeping the optical signal Transfer Quality, can produce between first optical fiber and second optical fiber around axial rotation, make the twisting stress on the win optical fiber or second optical fiber obtain discharging, tubular connection member and column connecting elements constitute by polytetrafluoroethylmaterial material, can reduce the frictional force between tubular connection member and the column connecting elements.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention connects the optical fiber of cut-out by two collimators, can rotate around axial mutually between two collimators simultaneously, so can when keeping the optical signal Transfer Quality, make the twisting stress on the optical fiber obtain discharging, thereby service life that has kept medical detection optical fiber.
