△) is a manufacturing mold that is immersed in a mixed solution of natural rubber latex, and a film of natural rubber of 0.15 to 0.25 amrl is adhered to the mold and dried to form a transparent 11g1 shape with elasticity. A spherical expansion part (3) is formed on one side of the shaped fixing part (1) through a constriction part (2), and the film thickness of the constriction part (2) is different from that of the fixation part (1) and the expansion part (3). ) is thicker than the film thickness.

The distal end (b) of the speculum (B) is inserted and fixed by any means such as tying with surgical thread or using adhesive. Therefore, it is preferable that the outer diameter is approximately the same as the outer diameter of the tip portion (b) or slightly larger, but it may be slightly smaller.

ある。The inflatable part (3) is formed in an almost spherical shape at the tip of the constricted part (2), has elasticity, and is inflatable.The inner diameter is slightly smaller than that of the fixed part (1), but it is the same. The diameter may be large or large, and the apex (3') has the same thickness or is slightly thicker, and can be adjusted to an appropriate size by injecting physiological saline through the channel of the endoscope or the air/water supply port. Let it expand. Due to this expansion, it comes into close contact with the inner surface of the blood vessel, making it possible to stop the flow of blood and further reducing the membrane thickness, making it possible to see through the membrane and allow laser beams to pass through it. The swelling also presses on the bleeding site or lesion to stop the bleeding or widen the stenosis. Incidentally, it is optional to provide a tear-preventing film that expands and contracts with expansion at the apex portion (3').

病巣を焼いたりなどその治療効果が大となる。Thickness (unit: shoe) Diameter and length (unit: am) Effect> The present invention forms a spherical expansion part on one side of a cylindrical fixing part through a constriction part in the same body by infiltration molding of the main body, and the constriction part Since the membrane is thicker than that of the fixed part and the expansion part, the shaping of the main body is extremely good, and
By removing this from the tip of the endoscope, it is possible to prevent blood, secretions, etc. from adhering to the light guide, objective lens, optical fiber, etc. Moreover, it is possible to prevent blood, secretions, etc. from adhering to the light guide, objective lens, optical fiber, etc. When the spherical expansion part is inflated by injecting physiological saline, the constriction exerts a tightening effect, and the expansion part located at the tip easily expands, creating a predetermined space by the expansion. The affected area is easy to see, making observation and diagnosis easier, and the affected area can be reliably irradiated with laser beams that pass through optical fibers, such as YAG laser or argon laser, to stop bleeding,
It has great therapeutic effects, such as burning away lesions.
