摘要： A forceps of endoscope comprises a clip that is provided with at least three arms and a base end portion. The arms are connected to the base end portion. Each of the arms has an open-close deforming portion located close to the base end portion. A core member is provided inside the clip to be in contact with an inner surface of the open-close deforming portion at least when the arms are open. A clip open-close ring is operated by remote control performed from the base end of the sheath. The clip open-close member is engaged with the open-close deforming portion to open and close the arms with a substantially equivalent angular interval and so as to prevent each of the arms from crossing each other.

摘要： A flexible tube for an endoscope which has excellent insertion operability is disclosed. The flexible tube includes and an elongated flexible tubular body constructed from a core body having a hollow space and an outer cover which is provided over the outer periphery of the core body and formed into a laminated structure having a plurality of layers. The tubular body is formed with a plurality of easily bendable portions which are provided in a spaced apart manner along the longitudinal direction thereof, each of these easily bendable portion being adapted to bend locally with a smaller curvature radius when the flexible tube is bent in one direction. The average interval between the adjacent easily bendable portions is preferably in the range 50-400 mm. The easily bendable portions is formed by locally changing the flexural rigidity of the outer cover. For example, it is formed by changing the thickness of at least one layer of the laminated structure of the outer cover at a position corresponding to the easily bendable portion.

摘要： The endoscope has a guide tube which has a flexible part at its distal end which can be bent by a remote control. The flexible part is enclosed in a flexible and elastic double walled tube consisting of an inner flexible tube (16) and an outer flexible tube (17). Any increase in diameter of the inner flexible tube (10) is prevented by a layer of braid (18) fitted between the inner and outer flexible tubes (16, 17). A second layer of braid (19) is fitted inside the inner flexible tube. USE/ADVANTAGE - Endoscope guide tube with reinforced flexible part to withstand high internal pressures during sterilisation.
