Chain and steel wire rope connecting structure and endoscope

Abstract

The invention provides a chain and steel wire rope connecting structure used for connecting a chain with a steel wire rope in the endoscope operation portion. The chain and steel wire rope connecting structure comprises a connecting piece, a hollow welding pipe and the steel wire rope, wherein the connecting piece is provided with a first concave portion and a second concave portion, the hollow welding pipe is assembled in the concave portions, the hollow welding pipe and the steel wire rope are welded into a whole, the hollow welding pipe comprises a pipe body and a pipe cap, and the pipe body is sleeved with an open washer. According to the connecting structure, the tightness degree of the steel wire rope can be adjusted by increasing or decreasing the number of the open washer or adjusting the specification of the open washer, and therefore the tightness degree adjustment of the steel wire rope can be better, and the assembly can be more conveniently conducted.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a connection structure between a chain and a steel wire rope and an endoscope. Background technique [0002] see figure 1 , The flexible endoscope usually consists of an insertion part 1 that can be inserted into the body and a bending operation part 2 connected to the base end of the insertion part 1 . The insertion part 1 is composed of a slender insertion hose 11 , a bent part 12 connected to the front end of the insertion hose, and a head end 13 connected to the front end of the bent part 12 and arranged at the front end of the insertion part 1 . The base end of the insertion tube 11 is connected to the operation part 2 . [0003] The operating part 2 controls the bending part 12 to bend up, down, left, and right through four wire ropes, and guides the end part 13 of the endoscopic lens to a suitable observation or operation position. Four steel wire ropes are placed in...
