Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 As shown, an endoscope in this embodiment at least includes a turning portion and a bending portion, wherein the turning portion includes a metal tube 300 , and the metal tube 300 is provided with a hollow groove 400 along the axial direction. It should be noted that the turning portion is a prior art structure, and the purpose of the hollow groove 400 is to soften the metal tube 300 to achieve 360° random bending. As for the specific structure of the hollow groove 400, since it belongs to the prior art, it is not included in this implementation. The example will not go int...

Abstract

The invention relates to the technical field of medical apparatus and instruments, and particularly discloses an endoscope snake bone structure and an endoscope. The endoscope snake bone structure comprises two or more snake bone units which are connected end to end, the adjacent snake bone units are connected through a pivot joint mechanism, the inner surface of a rotation groove of a pivot female joint is an inner conical surface of which the radius gradually increases from the outer walls to the inner walls of the snake bone units, the outer surface of a rotation portion of a pivot male joint is an outer conical surface of which the radius gradually increases from the outer walls to the inner walls of the snake bone unit, and the maximum radius of the outer conical surface is larger than the minimum radius of the inner conical surface. According to the endoscope snake bone structure, the adjacent snake bone units can relatively rotate around a pivot joint structure, accordingly, the adjacent snake bone units cannot be separated in the radial direction, through a processing mode of material removal, hollowed-out processing integrated shaping is conducted, assembly among the snake bone units is not needed, the machining efficiency is improved, and the stability and reliability of the structure are also improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope snake bone structure and an endoscope. Background technique [0002] An endoscope is a commonly used medical instrument, and the endoscope usually includes a curved portion, the curved portion is composed of a snake bone, and the snake bone includes several snake bone units connected to each other. In the prior art, the hinged connection between the adjacent snake-bone units is usually achieved through pin assembly. The endoscopic snake bone structure of this kind of structure is complicated to assemble, and the production process is many, and the pin shaft assembly is prone to failure during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a structurally improved endoscope snake bone structure and an endoscope to solve the related defects of the prior art. [0004] In order to solve the...
