摘要:
An injector instrument and a forceps tap for use with an endoscope. The injector instrument is provided with at least one needle formed of a synthetic resin and is further provided with a variety of stopper devices which limit the amount that the needle can extend from the endoscope. The injector instrument may be formed having a curved or easy-to-bend portion. The forceps tap is provided at the entrance to a forceps channel of the endoscope to accommodate at lease two injector instruments or other treatment accessories such that the treatment accessories can be inserted in a single forceps channel and such that substances (such as internal fluids from a human cavity) are held inside the forceps channel.

The treatment accessory for an endoscope is inserted in or removed from a forceps channel of the endoscope through an inlet of the forceps channel. The treatment accessory includes a treatment device and a flexible shaft. The treatment device is provided at a first end of the flexible shaft. The flexible shaft is provided with a marking at a predetermined portion thereof. The treatment device is located at a predetermined position inside the forceps channel when a predetermined portion of the marking is located at the inlet of the forceps channel.

A flexible tube for an endoscope that includes a spiral tube, a netted tube that covers the outer surface of the spiral tube, and a jacket. The netted tube is formed by braiding a plurality of strand bundles each formed by closely arranging a plurality of fine wires in parallel. The jacket is made of a flexible synthetic resin which covers the outer surface of the netted tube. The braid density K of the netted tube lies in a range of 0.772.ltoreq.K.ltoreq.0.906.

摘要:
A flexible tube for use in an endoscope comprises a flexible basic tubular core structure including an outer meshwork tube, and a thermoplastic synthetic resin tube bonded to the outer meshwork tube of the tubular core structure in a manner such that the resin tube maintains an inherent compressive pre-stress in the finished flexible tube. An endoscope tube having flexibility which varies in a step-wise manner from one end of the tube to the other is obtained by integrally bonding two or more thermoplastic synthetic resin tube sections formed of respective resin materials having different hardnesses to the outer surface of the tubular core structure to form a coating layer in an analogous manner. The ends of adjacent tube sections substantially abut each other and upon heating the tube sections to a temperature only slightly higher than a softening point but lower than a melting point of any one of them, the localized regions of the respective pairs of abutting tube section ends are heated to a temperature which is as close as possible to a melting point of one of the tube sections having a higher melting point than that of the other tube section, whereby the end of the other tube section having a lower melting point is fused with the end of the adjacent tube section, and after cooling of the tube sections, a continuous and integral tube is obtained without any joints or junctures.
摘要:
A device for changing a direction of the top end part of an endoscope in which a manual operating section is coupled to a top end part curving section through wires and the top end part curving section is curved vertically and horizontally by pulling the wires. A pair of wires are adapted to drive the top end part curving section vertically and horizontally, respectively, and a pair of drive members pull the wires directly or through intermediate members. Rotating knobs are integrally coupled to the pair of drive members so as to control the top end part curving section vertically and horizontally. A pair of brake drums confront one another, and a frictional member or brake shoe is mounted on a stationary member of the device in such a manner that it is movable with respect to the pair of brake drums. An external operating lever controls the movement of the brake shoe and the brake shoe abuts against the pair of brake drums by operation of the external operating lever so that simultaneous braking occurs.

An apparatus for adjusting the light source position of a light source assembly comprises a lamp socket for mounting a lamp at an eccentric position thereon, and a sleeve secured to a lamp housing for mounting the lamp socket so as to be slidable along the axis and rotatable about the axis of the sleeve. By axially sliding the lamp socket relative to the sleeve or by rotating the lamp socket about the axis, the position of the lamp can be optimally adjusted relative to a condenser which is mounted on the lamp housing.

An arrangement for detachably mounting an examining member onto a microscope comprises a horizontally extending dovetail key on the examining member, and a horizontally extending dovetail groove formed in the body of the microscope. The dovetail connection permits the examining member to be mounted in place through its horizontal movement, thereby facilitating its mounting and removal.
摘要:
A high-frequency treating instrument for an endoscope, includes: a spatula-form high-frequency electrode which is adapted to be protruded from and housed within an insulated flexible sheath of the endoscope; and a concavo-convex portion which serves as an antiskid member when the concavo-convex portion is brought into contact with a mucous membrane and is formed on at least one of side edge portions of a portion closer to a tip end of the high-frequency electrode.
摘要:
A high-frequency treatment tool for an endoscope is provided with a transparent hood to be detachably coupled to a distal end of an endoscope provided with at least one electrode, at least one high-frequency electrode provided at a tip end of the transparent hood, at least one contact which is to electrically contact the at least one electrode of the endoscope, and at least one conductive member that electrically connects the at least one high-frequency electrode and the at lease one contact. The at least one conductive member is arranged to be located at an inner position with respect to an outer surface of the transparent hood.
