Embodiment 1

[0027] Example 1, see figure 1 , figure 2 , image 3 , a hose with adjustable stiffness, including a main hose 1; several electromagnets 4 are arranged in a row along the axial direction in the main hose 1, and there is a set distance between adjacent electromagnets 4, and through The arrangement of the north and south poles facing each other enables two adjacent electromagnets 4 to form a magnetic coupling, and the electromagnet 4 forms a relatively fixed connection with the pipe wall of the corresponding pipe section of the main hose 1 . Among them, three rows of electromagnets 4 are arranged along the circumferential direction of the main hose 1; a spring tube 3 is fixedly connected in the main hose 1; the electromagnet 4 is located in the spring tube 3 and passes through the spring tube 3 settings.

[0028] Wherein, except for the two electromagnets 4 at the outermost ends of the nozzles at both ends of the main hose 1, the contact lengths of other electromagnets 4 fix...

Embodiment 2

[0032] Example 2, see Figure 4 , The difference between this embodiment and Embodiment 1 is that the spring tube is omitted, and the electromagnet 4 directly forms a fixed connection with the main hose.

[0033] The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0034] Example 3, see Figure 5 , an operating part for an endoscope, comprising the flexible tube 1 with adjustable stiffness in embodiment 1 or 2, wherein a regulator 2 is provided on the operating handle, and the regulator 2 is used to adjust the flow rate in the flexible flexible tube 1 with adjustable stiffness. The magnitude of the current through the electromagnet is used to adjust the magnitude of the electromagnetic force, and the stiffness of the hose 1 can be adjusted by changing the stiffness accordingly.

Abstract

The invention discloses a rigidity-adjustable hose, an operating part, an insertion part and an endoscope. The rigidity-adjustable hose includes a main hose; inside the main hose, several electromagnets are arranged in a row along the axial direction, correspondingly There is a set distance between adjacent electromagnets and magnetic coupling can be formed, and the electromagnets form a relatively fixed connection with the pipe wall of the corresponding pipe section of the main hose. Preferably, the electromagnet adopts an oval or crescent shape, and the electromagnet is arranged through a spring tube. The operation part and the insertion part include the aforementioned hose. The endoscope includes the aforementioned operation portion and / or insertion portion. The beneficial effect of the invention is that the rigidity-adjustable hose has a simple structure, is convenient to use, and can be adjusted in rigidity with a large adjustment range and sensitive action. The operating part and insertion part for an endoscope having the aforementioned flexible tube, and the endoscope having the operating part and / or the inserting part all have the same rigidity adjustment function as the flexible tube.

Description

technical field [0001] The invention relates to a medical endoscope structure, in particular to an adjustable rigidity hose, an operation part with the hose, an insertion part with the hose and an endoscope with the operation part and / or the insertion part. Background technique [0002] The operating part of the medical endoscope is used to control the bending movement of the head up, down, left, and right. The doctor holds the operating part to control the movement of the head end, so as to complete the inspection and operation of the relevant digestive tract. Doctors need to perform a large number of operations every day. The comfort of operation directly affects the doctor's experience, and also indirectly affects the surgical effect. The operating habits of each doctor are different, and the requirements for the hardness of the main hose of the insertion part are also different. In order to meet the needs of each doctor for the hardness of the main hose of the insertion ...
