Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laser scalpel tip adapter that allows an operator to treat an affected area in a recess or the like on the surface of a living body with a laser scalpel while directly viewing it.

FIG. 1 is a diagram showing an overview of a laser scalpel.

1 is a laser main body, 2 is a manipulator (within a circle), 3 is a probe (within a double circle), and 4 is an adapter (with diagonal lines).

The laser beam oscillated by the laser main body 1 propagates within the manipulator 2 as a parallel beam and reaches the probe 3 at the tip. An adapter 4 having a built-in lens for focusing the laser beam is attached to the tip of the probe 3, and the focused beam is irradiated onto the affected tissue of the living body to perform incision or hemostasis. FIG. 2 is an explanatory diagram of the conventional adapter 4 in use.

A laser beam 6 focused by a condensing lens 5 attached to the adapter body 4 is irradiated onto an affected part 7 of the living body.
This conventional adapter 4 directs the focused beam to the affected area 7.
As shown in FIG. 3, when treating the affected area 7 in the recess, the operator's view of the affected area 7 is blocked by the adapter 4, making it difficult to properly treat the affected area 7 in the recess. was difficult. Furthermore, as shown in FIG. 4, there is a drawback that the laser beam 6 cannot be irradiated to the affected area 7, such as the inner wall of the body cavity, which is not exposed to the body surface. SUMMARY OF THE INVENTION An object of the present invention is to provide a laser scalpel tip adapter that allows an operator to treat an affected area in a recess or an inner wall of a body cavity that is not exposed to the surface of a living body with a laser scalpel while directly viewing it.

The present invention will be described in detail below with reference to the drawings.
FIG. 5 is a diagram showing an embodiment of the laser knife tip adapter of the present invention.

Reference numeral 8 denotes a tip adapter made of a thin metal pipe made of copper, gold, silver, aluminum, various alloys, or annealed stainless steel. They are attached to the laser female adapter 4 so as to match.

The inner surface of the metal pipe 8 is chemically polished, electrolytically polished, or plated with a highly reflective metal such as gold or silver to make it sufficiently smooth for the wavelength of the laser beam. Further, since the metal pipe 8 is thin, it can be bent freely according to the position of the affected area, and furthermore, it can be removed and replaced depending on the affected area. 3 Condensing lens 5
The focused laser beam 6 propagates through the inner surface of the metal pipe 8 while being repeatedly reflected, and is guided to the end of the pipe.

Since the diameter of the laser beam 6 emitted from the end of the pipe is sufficiently narrow, it can be used for hemostasis treatment and soft tissue incision over a relatively wide range. FIG. 6 is a diagram showing another embodiment of the laser knife tip adapter of the present invention.

In this embodiment, a second condensing lens 9 is provided at the end of the metal pipe 8 to refocus the laser beam 6 and narrow its diameter to an extremely small diameter. With this adapter, the laser scalpel can be used for surgeries involving minute parts, surgeries that require high precision, surgeries that require high power density, etc. 7 and 8 are examples of the use of the laser knife tip adapter of the present invention.

Since the metal pipe 8 is thin and can be bent freely, it can be used to treat recesses while looking directly at the affected area, as shown in Figure 7, and to treat inner walls of body cavities, as shown in Figure 8. became possible. The effect of the present invention is that the laser beam is irradiated onto the affected area from the end of a thin flexible metal pipe, so it is possible to treat the affected area in a concave area with a laser scalpel while directly viewing the affected area. It has now become possible to treat affected areas that are deep inside the body, such as the inner walls of body cavities.

Application fields of the present invention include laser scalpels, laser coagulators (hemostatic devices), and the like.
