Abstract

The invention provides an endoscope which comprises an insertion part, a traction line, a spring tube and a handle. The insertion part includes an insertion tube and a bending part; the bending part is arranged at the front end of the insertion tube; the insertion tube is located at the tail end of the bending part; one end of the traction line penetrates the insertion tube from the tail end to beconnected with the front end of the bending part; the spring tube is accommodated in the insertion tube and sleeves the traction line, and one end of the spring tube is connected with the tail end ofthe bending part; the handle is provided with a drive structure, a support and connecting tubes; threaded holes are formed in the support; each of the connecting tubes is provided with an outer thread; one ends of the connecting tubes are in threaded connection with the corresponding threaded holes through the support, the other end of the traction line penetrates the connecting tubes and the threaded holes to be connected with the drive structure on the handle, and the other end of the spring tube is arranged at one ends close to the insertion part, of the connecting tubes in an abutted manner. The endoscope is simple in structure, and accurate installation of the spring tube is realized conveniently.

Description

Technical field [0001] The invention relates to an endoscope component, particularly an endoscope. Background technique [0002] The endoscope includes a handle and a bending part. The handle is provided with a driving structure. One end of the traction wire is connected with the driving structure, and the other end penetrates into the bending part. The driving structure drives the bending part to turn by pulling the steel wire. In order to facilitate the force transmission of the traction wire and ensure the traction effect of the traction wire on the bending part, the traction wire located in the bending part is usually covered with a spring tube, and the two ends of the spring tube need to be resisted and fixed in order to achieve the effect of the traction wire. Traction. [0003] Generally, one end of the spring tube needs to abut against the handle, and the other end to abut against the curved part. However, there may be errors in the manufacturing process and assembly p...
