Abstract
The utility model provides a laser surgical knife bit with telescopic contact lever. The knife bit mainly is composed of a light pipe, a focusing lens, a telescopic contact lever and a handle. The laser surgical knife bit is characterized in that without applied force, the bit of the telescopic contact lever can be on the same plane with the smallest light spot which is formed by laser after focusing, so that an operator can accurately aim at the site of focus under the guidance of guiding light and the contact lever. Contact feeling can be felt while in use, and the knife bit can be telescoped along with the pressure of hands, so that the contact feeling can be increased, and the size of the lasing irradiating light spot can be changed.
Description
Technical field
This utility model is to be placed on the various laser surgery machines, is used for accurately aiming at a kind of device that lesions position undergos surgery and treats.
Technical background
At present, known laser surgery cutter head has two kinds, a kind of is non-contact laser scalpel head, this cutter head does not in use directly contact lesions position, but the doctor in use is difficult to hold, in case contact with lesions position, can be attached to the tissue in optical fiber exit because of the zoom that is heated, stop up light-emitting window, the laser that reflects back can damage optical fiber even damage laser instrument.Another is a contact laser operation cutter head, and this cutter head in use can directly contact lesions position, and attachment still can pollute cutter head because of the blackout of being heated, and influences surgical effect.
Summary of the invention
In order to overcome that existing laser scalpel is difficult to control and problem such as contact stain, this utility model provides a kind of new pattern laser operation cutter head, not only makes the doctor that tactility is arranged in use, does not also use directly contact lesions position of shaven head, avoids contaminated.
The technical scheme that its technical problem that solves this utility model adopts is: be fixed with spring in handle, be connected with feeler lever, parallel placement with light pipe, the place is fixed with condenser lens at the light pipe light-emitting window, when flexible feeler lever is not subjected to external force, contact and laser focusing point are on the same horizontal plane, during use, contact lesions position with feeler lever, can control the position of laser irradiation accurately, and the pressure that can whip of feeler lever is different and stretch, can increase the size of sense of touch and change laser irradiation hot spot like this, the control exposure dose is to reach cutting, evaporation, vaporization, medical purpose such as condense.
The beneficial effects of the utility model are, and are simple in structure, utilize contact lever can avoid out shaven head directly to contact with tissue, have tactility simultaneously, are convenient to locate, and control operation process.
Description of drawings
Fig. 1 is a principle schematic of the present utility model.
In Fig. 1,1 is light pipe, and 2 is condenser lens, and 3 is contact lever, and 4 are the fixing spring of contact lever, 1,2,3,4, all be installed in the handle 6.5 is the focussing plane behind the laser beam line focus lens 2.
The specific embodiment
Light pipe (1), condenser lens (2), contact lever (3) and spring (4) are fixed in the handle (6), and contact lever (3) is connected with spring (4), and parallel with optical fiber (1).Spread out of from laser instrument the laser that comes by light pipe (1) and condenser lens (2) after, focus on the plane (5).When spring (4) in the raw the time, the contact of contact lever (3) and the focus point of light coexist on the plane 5.Can directly contact biological tissue with contact lever, rely on support, the indication of contact lever, laser focusing point can be aimed at lesions position, contact lever can stretch with the difference of hand pressure, can change the diameter of irradiation hot spot as required.
Claims (3)
1. novel laser surgery cutter head, it is characterized in that being equipped with in the handle (6) contact lever (3) that is connecting spring (4), parallel with light pipe (1), the focus point behind the laser process condenser lens (2) and the contact of contact lever (3) are in when contact lever is not subjected to external force on the same focussing plane (5).
2. laser surgery cutter head according to claim 1 is characterized in that light pipe is an optical fiber.
3. laser surgery cutter head according to claim 1 is characterized in that handle is metal canula or plastic bushing.
