Abstract

PURPOSE:To achieve an operation with the same operating touch as would be in operation using an ordinary scalpel by arranging a section for observing patients which is provided on the outer circumference of a light guiding body for guiding a laser light as connected to a chip with a sharp tip to allow the transmission of the laser light and also connected to a section for preventing the leakage of the laser light and a photoconductor and a laser oscillating section. CONSTITUTION:A laser oscillation adjuster 8 is adjusted to regulate the intensity of a laser light from a laser oscillating section 7 and then, a state of emitting a laser light from a chip 2 is optimized. Under such a condition, an affected part of a patient is excised with a sharp tip 2a of the chip 2 observing the affected part through an observing section 6 and it is irradiated with the laser light at a desired location to be treated. When the desired location to be treated exists deep in vivo, first, the sharp tip 2a of the chip 2 sticks into the affected part and the laser light is irradiated observing the location to be treated with the observing section 6. This enables the treatment of the desired location to be treated only.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a medical device, and in particular, the sharp tip of the tip is brought into direct contact with the affected area to allow the tip to enter or incise the affected area, and the tip is inserted into or incised into the affected area using a laser beam. The present invention relates to a novel improvement that enables surgery to be performed with the same operating sensation as operating a scalpel by treating the affected area.

[Conventional technology]

There are various types of medical instruments that use this type of laser light that have been used in the past, but the following two configurations (not shown) can be mentioned as representative ones. 1) The affected area was treated by placing a chip in a non-contact state and irradiating laser light emitted from the chip.

(2) Glass or 5iOz was mainly used as the material for the chip.

[Problem to be solved by the invention]

Conventional medical instruments were constructed as described above, so
The following issues existed.

(1) Since the tip and the affected area are held in a non-contact state and the laser beam is irradiated to the affected area, it is not possible to obtain the operational feeling of making an incision with a conventional scalpel, and the surgery requires skill and a high degree of skill. It required technology.

(2) When treating a deep affected area, the entire key may be damaged by the laser beam before reaching the affected area, making it unsuitable as a means of treating deep affected areas.

(3) Since the tip and the affected area are not in contact, the energy of the laser beam is attenuated and the treatment area is limited.

(4) Since the chip is made of Sin, glass, etc., the wavelength of laser light that can be used is limited, and it is not suitable for all treatments.

(5) Since the chip is 5 in 2 and made of glass or the like, irradiation with a laser beam with high energy density causes significant damage to the chip, requiring frequent chip replacement.

(6) Since the chip is made of SiO□, glass, etc., the surface of the chip corrodes and becomes cloudy, which significantly reduces the therapeutic effect.

(Because the tip was made of 5102, glass, etc., blood etc. easily adhered to the tip, reducing the therapeutic effect.

(8) Since the chip is made of Sin, glass, etc., the strength of the chip is low and it often breaks.

The present invention is an attempt to solve the above-mentioned problems.In particular, the sharp tip of the tip is brought into direct contact with the affected area, and when the tip enters the affected area, an incision is made, and a laser beam is used to treat the affected area. The purpose of the present invention is to provide a medical instrument that allows surgery to be performed with the same operational feeling as operating a scalpel.

Means for Solving Problem C] A medical device according to the present invention includes a chip having a sharp tip and capable of transmitting laser light, a light guide connected to the chip for guiding the laser light, and the light guide. A light leakage prevention part is provided on the outer periphery of the body to prevent leakage of the laser beam, and a light leakage prevention part is connected to the light guide to protect the affected area! This configuration includes an i-Kyoto for detecting the laser beam, and a laser oscillation unit connected to the light guide and generating the laser beam.

More specifically, the tip has a conical configuration.

More specifically, the tip is made of diamond.

[For production]

In the medical device according to the present invention, since the tip has a sharp tip, by bringing the sharp tip into contact with the affected area in a scalpel-like manner, the affected area is incised, and the target area after the incision is targeted with a laser beam. It can be treated by

When performing laser light treatment on deep affected areas using a sharp tip, the sharp tip can be inserted directly into the deep part, and once the target area has been reached, the laser light treatment can be performed. .

Furthermore, when diamond is used for this chip, it has high heat resistance, corrosion resistance, abrasion resistance, water resistance, blood resistance, and strength, so it can be used with high energy density laser light by optionally using laser light of various wavelengths. It is possible to irradiate the chip, prevent clouding, blood adhesion, and destruction of the surface of the chip, and perform laser light therapy that involves incision in the affected area.
