Description
1 BACKGROUN~ O~ TIIE INVENT~ON
This inven-tion relates to an improvement in a manipulator for a laser k~ife which uses an op-tical fiber as a light conducting path.
S BREIF DESCRIPTION OF THE DRAWINGS
In the accompanyiny drawings:
Fig. 1 is a longitudinal sectional view o~ the emergent end portion o~ an example of a conventional laser knie manipulator;
Fig. 2 is a longitudinal sectional view of -the end portion of another example of the conventional laser knife manipulato~;
Fig. 3 is a lonyitudinal sectional view of the end portion of an example of a laser knife manipulator according i 15 to this invention; and Fig. 4 is a longitudinal sectional view of the end portion of another example of a laser knife manipulator according to the invention.
Laser beams are monochromatic and are excellent in directivity. When a laser beam is focused at a minute point, great energy can be locally obtained. Therefore, laser beams are utilized as laser knifes in the field of medical treat-ment, and especially when a limi-ted part of the body is subjected to such medical treatment or surgical operation the use of the laser kniEe is quite effective, With a laser knife, a laser beam from a laser oscillating section is applied to that part o~ the hody 3~
1 which is to ~e subjected to the medical -treatrnent or surgical operation. In this opera-tiorl, it is required -that the laser beam be correctly applied to an extremely small target. In order to meet this requiremen-t, an op-tical fiber of small weight and excellent flexibili-ty is frequently used as the light conductiny path.
In most laser knife manipulators using optical fi~ers as light conductiny pa-ths, the laser beam is applied to the part to be irradiated, with the cover 2 of the op-tical fiber 1 gripped directly, as-shown in Fig. 1, which is an explanatory diagram of the front end portion of a manipulator.
Accordingly, the op-tical fiber 1 is liable -to bend during irradiation, as a result of which it is impossible to correctly apply the laser beam to the body part ~o be irradiated, and the temperature of the manipulator is increased by the reflected light.
In order to overcome these drawbacks, a laser knife manipulator has been proposed in the art, in which, as shown in Fig. 2, the front~ end portion of the optical fiber 1 is inserted into a hand piece 3 which is made of a straight pipe of metal or synthetic resin. However, this conventional manipulator still suffers from drawbacks in that it is difficult to apply the laser beam in directions o-ther than the axial direction of the hand piece 3; i.e., sometimes the target cannot be lined up with the hand piece and irradiated wi-th the laser beam, with t~e result tha-t the ranye of application of the device in medical treatements or surgical operations is limited.
:~, 1 SUMMARY OF T~-IE :[NVENTION
Accordinyly, an object of th:is ,invention :is to eliminate the above-described drawhacks accompanying a con-ventional laser knife manipulator., More speci.fically, an object of the invention is to provide a laser knife manipulator with which a laser beam can be correctly applied to a.ll parts to be irradiated irrespective of the positions and -the configurations of such parts.
The foregoing object and o-ther objects as well as .the characteristic features of the invention will become more apparent from the folIowing detailed description, when read in conjunction with the accompanying drawinys, in which like parts are designated by like reference numerals.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A first example of a laser knife manipulator according to this invention, as shown in Fig. 3, includes an optical fiber 1 as a light conducting path adap-ted to conduct the laser beam from a laser oscillating section (not shown~; and a hand piece 3 detachably disposed over the end portion of the optical :Eiher 1. The hand piece 3 is suitably shaped according to the configuration and the position of the part to be irradiated with the laser beam. ~lore specifically, the hand piece 3 is made of a metal or synthetic resin and has an inside diameter which is slightly larger than the outside diameter of the cover 2 of the optical fiber. One end portion of the hand piece 3 is bent as shown in Fig. 3. ~lale threads are formed on the outer wall of the other end portion of the hand piece. The manipulator further includes a rubber sleeve 4 having an O-ring-shaped protrusion at one end; and a cap 5 having female threads on the inner wall thereof. The rubber sleeve 4 is positioned over the optical fiber cover 2 in such a manner that the rubber sleeve 4 is adjacent the hand piece 3, and is held there by its own elastic force. Under this condition, the cap 5 is screwed onto the threaded portion of the hand piece.
In other words, first the cap 5 and the rubber sleeve 4 are placed over the optical ~iber cover 2, and then the optical fiber 1 is inserted into the hand piece 3. Under this~
condition, the cap 5 is screwed on the threaded portion of the hand piece 3. As a result, the O-ring-shaped protrusion o-f the rubber sleeve 4 is pressed against the hand piece 3, so that the hand piece 3 is fixedly secured to the cover 2.
It goes without sayin~ that the hand piece 3 can be readily removed from the optical fiber 1 by unscrewing the cap 5.
A variety of hand pieces such as straight hand pieces and bent hand pieces of different radii of curvature can be - '1 -fabricated separately according to the con~iguration and the posi-~ion of the body parts to be i.rradiated. Accordingly, with a suitable hand piece, the laser beam can be applied correctly to the desired location, and the target to be irradiated will never be obscured by the operator's hand.
If the hand piece 3~ the rubber sleeve 4 and the cap 5 are removed from the otpical fiber ]., then the latter can be readily inserted into the laser knife insertion hole o~ a conventional endoscope, so that it can be used with such an endoscope.
Another example of a laser knife manipulator according to the invention is as shown in ~ig. 4. In this example, an optical ibe~ 6 is fixedly inserted into a hand piece 3 which ; has been shaped as desired, and when the hand piece 3 is secured to an optical fiber 1, the latter is optically coupled to the optical fiber 6.
For this purpose7 a coupling lens 7 is fixedly secured to the coupling end o-f the optical fiber 6 in the hand piece 3.
In this example, lens 8 for condensing the laser beam is -fixed to the other end of the optical fiber 6 in the hand piece 3.
Similarly as in the first example shown in Fig. 3, a rubber sleeve 4 and a cap 5 are placed over the optical fiber l which is to be coupled to the hand piece 3. A lens holder 10 holds a coupling lens 9 which is set at the front end of the optical fiber 1. The lens holder 10 is threadably engaged with the cap 5O
A coupling nut 11 is provided on the lens holder 10. The coupling nut 11 is used to fixedly couple the lens holder 10 to the hand piece 3.
First, the front end portion of the optical fiber ], on which the rubber sleeve ~ and the cap 5 have been mounted, is inserted into the lens holder 10. Then, the cap 5 is screwed on the lens holder 10, so that the latter 10 is fixedly secured to the front end portion of the optical fiber. Then, the coupling nut 11 is tightened so that the hand piece 3 witn the optical fiber ~ is fixedly secured to the lens holder 10. As a result, the optical fiber 1 is optically coupled to the optical fiber 6, and the hand piece 3 is fixedly secured.
In the second e~ample described above, two lenses are used for optical coupling; however, the number of lenses may be one or more than two.
As is apparent from the above description, a number of hand pieces which are shaped as desired according to khe configuration of the body part to be irradiated with the laser beam can be selectively and readily used. Therefore, ~he -laser beam can be correctly applied to that part which is to be irradiated. Furthermore, the invention makes it possible for one laser knife to perform dental and oral surgical operations~
as well as surgical operations in other fields. In addition, the laser knife manipulator can be readily coupled ko an endoscope. Thus, the laser knife manipulator according to the invention has a wide range of application.
This inven-tion relates to an improvement in a manipulator for a laser k~ife which uses an op-tical fiber as a light conducting path.
