Detailed Description
The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.
Example one
Referring to fig. 3 and 4, the spring tube fixer of the endoscope operation portion includes at least one spring tube fixing device 1, and each spring tube fixing device 1 includes a fixing guide seat 1A, a first connecting mechanism 2A and a second connecting mechanism 3A for connecting a spring tube 3 and a wire rope 4.
The fixed guide seat 1A is a main body portion of the spring tube fixing device 1, and generally adopts a structure with a regular shape, such as a polygonal prism structure, for example, a quadrangular prism, a hexagonal prism, an octagonal prism, and the like. Seted up first through-hole 4A on fixed guide holder 1A, the size of first through-hole 4A internal diameter matches with the external diameter size of spring pipe 3, can be a little bigger for supply spring pipe 3 to insert and weld together, make spring pipe 3 and this spring pipe fixing device 1 fixed connection together, firm in connection and be difficult for droing when using.
The fixed guide base 1A is provided with a first connecting mechanism 2A, the first connecting mechanism 2A is a connecting structure for connecting the fixed guide base 1A to other components of the endoscope operating section, and usually, the endoscope operating section includes a fixing plate 2 for mounting the spring tube fixing device 1 therein, that is, the fixed guide base 1A is connected to the fixing plate 2 or other structures through the first connecting mechanism 2A.
The fixed guide seat 1A is further provided with a second connecting mechanism 3A, and the second connecting mechanism 3A is a structure for connecting two different fixed guide seats 1A to each other. Because the endoscope operation part usually comprises a plurality of spring tube fixing devices 1, the spring tube fixing devices 1 are connected at least in pairs, so that the mutual supporting and fixing effects can be achieved, and the structure of the whole endoscope operation part is more stable.
Therefore, referring to fig. 7, the present invention provides a method for installing a spring tube fixing structure of an endoscope operation portion, comprising: s1, connecting one end of the steel wire rope 4 with the steel wire rope connecting piece 5, and extending the other end of the steel wire rope into the spring tube 3 to finish installation; step S2, inserting the spring tube 3 into the first through hole 4A and welding the spring tube with the fixed guide seat 1A; step S3, connecting the fixed guide base 1A with other fixed guide bases 1A through the second connecting mechanism 3A; in step S4, the fixed guide 1A is attached to the fixed plate 2 by the first connecting mechanism 2A.
