Embodiment Construction

[0042] exist figure 1 In this case, an endoscope 2 includes an elongated tubular assembly 10 or insertion tube, a handle 11 and a universal cable 12 . The elongated tubular assembly 10 is advanced into a body cavity of a patient. A handle 11 is mounted on the proximal end of the elongated tubular assembly 10 . A universal cable 12 extends from the handle 11 . A processing device (not shown) is connected to the endoscope 2 via a universal cable 12 . The elongated tubular assembly 10 includes a tip member 13 , a diverter member 14 and a hose member 15 . A steering member 14 is mounted on the proximal end of the tip member 13 and is bendable for steering. A hose means 15 extends from the proximal end of the steering means 14 . The hose means 15 is several meters long for bringing the tip means 13 to the target location in the body cavity. A solder joint 16 or connector connects the steering means 14 to the hose means 15 .

[0043]The imaging unit is incorporated in the tip...

Abstract

A tube assembly for an endoscope includes a steering device and a flexible tube device on a proximal side. The tube assembly includes an inner sleeve. An outer sleeve receives one end portion of the inner sleeve in an axial direction, for connection of the flexible tube device to the steering device. A flow opening is formed in a portion of the outer sleeve disposed around the inner sleeve. A distribution groove is formed between an outer wall surface of the inner sleeve and an inner wall surface of the outer sleeve, to extend from the flow opening. A seal cavity is formed in the inner and outer sleeves to extend from the distribution groove in a direction away from the flow opening. Flowing solder material is supplied in the flow opening, charged in the distribution groove and the seal cavity, for attaching the outer sleeve to the inner sleeve.

Description

technical field [0001] The present invention relates to a tubular assembly and method of joining for an endoscope. More particularly, the present invention relates to a tubular assembly for an endoscope, in which a plurality of parts are connected to each other by using an inner cylinder and an outer cylinder, and the joint strength with a sealing material between the inner cylinder and the outer cylinder can be stabilized , and relates to a joining method for a tubular assembly. Background technique [0002] Endoscopes are medical devices widely used in diagnosis and treatment. An endoscope includes an elongated tubular assembly for accessing a body cavity, and a handle that is manually operated by a physician or operator. The elongate tubular assembly includes a tip member, a diverter member and a hose member. The top device includes an imaging unit with an image sensor such as CCD, CMOS sensor. The steering device includes a plurality of connection elements connected ...
