本考案は、膀胱結石、尿道結石、腎盂内の結石
等を除去するための結石破壊用レーザメスに関す

この方式が急速に採用されるようになつた。 Conventionally, treatment methods for stones containing calcium oxalate, calcium phosphate, calcium carbonate, etc. include lithotripsy performed using an endoscope, transurethral catheter, stone basket, etc., and open lithotripsy. The former is difficult to completely remove, the latter requires incisional surgery, and although stone dissolution methods are available, complete dissolution is difficult with current dissolving agents. Subsequently, it was discovered that concentrated projection of a CO 2 laser beam can destroy stones bloodlessly and that the removal efficiency is extremely high, and this method has been rapidly adopted in recent years.

出現が要望されていた。 In particular, as the introduction of a laser beam to the affected area by an extremely thin optical fiber became practical, there was a demand for a laser scalpel dedicated to destroying stones.

ある。 The present invention was developed in view of the above circumstances, and is dedicated to stone destruction.It has a fiber for guiding the CO 2 laser beam that destroys stones, and allows visual observation of the stone area during surgery if necessary. An image guide, a conduit for supplying water and air necessary to the stone site during surgery, and a suction tube for suctioning broken stone fragments to the outside are built into the hollow tube. When the beam is irradiated, a protector is provided that protrudes to protect healthy tissue from the beam, and it houses the necessary components of a scalpel for stone destruction that uses a CO 2 laser beam, and is used to destroy healthy tissue at the stone site. The object of the present invention is to provide a laser scalpel for stone destruction that facilitates close surgery.

水、吸引等の機能を兼備させることもできる。 FIG. 1 is a schematic perspective view of essential parts of a laser scalpel according to the present invention. All the necessary constituent members of the female are built into the hollow tube 1, and the tips of the members are exposed at or near the end surface of the hollow tube. The components built into the hollow tube 1 include a fiber 2 for guiding the CO 2 laser beam to destroy the calculus, an observation image guide 3 that allows internal visualization of the calculus, and a fiber for inflating the calculus or tissues in its vicinity. A conduit 4 for delivering air and water used for cleaning the stone area before, during, or after surgery, and a conduit 4 for transporting stone fragments crushed by CO 2 laser beam irradiation, contaminated cleaning water, etc. The suction tube 5 is capable of suctioning the beam and extending it to the vicinity of the focal point of the beam as shown by the reference numeral 5', and if necessary, it is hollow to the extent that it is inconvenient to enter the stone. It is also possible to add other members within the range where the tube does not have a large diameter (preferably 0.8 to 1.2 mm in diameter). Note that the conduit pipe 4 and the suction pipe 5 described above can be integrated into a single unit to have functions such as air supply, water supply, and suction.

鉗形等のいずれでもよい。 The important features of the laser scalpel according to this invention are:
A protector 6 is provided protruding from the tip of the hollow tube 1. This protector is used to isolate and protect healthy tissues other than the calculus from the high-energy beam. It can also be used to collect finely crushed stones. The protector is manufactured from soft plastic, rubber, or the like, and its shape may be circular, hemispherical, or crab-shaped as shown in the figure.
