Embodiment 1

[0060] like Figure 1-Figure 2 As shown, the endoscope structure includes an operating part, a passive bending part 2 and an active bending part 1 connected in sequence. The operating part can drive the active bending part 1 to bend. The active bending part 1 includes a first body 11, a second An outer weaving 12 and a first sheath 13, the passive bending part 2 includes a second main body 21, a second outer weaving 22 and a second sheath 23 that are covered in sequence, and the first main body 11 and the second main body 21 are provided with eight working channel 3. Among the eight working channels 3 , four working channels 3 are provided with internal weaving 5 , and one working channel 3 is provided with internal weaving 5 and inner membrane 6 . The first body 11 and the second body 21 are made of the same material, and the rigidity of the first body 11 is smaller than that of the second body 21 .

Embodiment 2

[0062] like Figure 3-Figure 5 As shown, the endoscope structure includes an operating part, a passive bending part 2 and an active bending part 1 connected in sequence. The operating part can drive the active bending part 1 to bend. The active bending part 1 includes a first body 11, a second An outer weaving 12 and a first sheath 13, the passive bending part 2 includes a second main body 21, a second outer weaving 22 and a second sheath 23 that are covered in sequence, and the first main body 11 and the second main body 21 are provided with eight working channel 3. Among the eight working channels 3 , four working channels 3 are provided with internal weaving 5 , and one working channel 3 is provided with internal weaving 5 and inner membrane 6 . A reinforcement channel 211 is provided in the second body 21 , and a reinforcement wire 4 is provided in the reinforcement channel 211 . like Figure 4 As shown, the first main body 11 is provided with an auxiliary channel 111 c...

Embodiment 3

[0064] like Figure 6-Figure 9 As shown, the endoscope structure includes an operating part, a passive bending part 2 and an active bending part 1 connected in sequence, the operating part can drive the active bending part 1 to bend, and the active bending part 1 includes a first main body 11, a second An outer weaving 12 and a first sheath 13, the passive bending part 2 includes a second main body 21, a second outer weaving 22 and a second sheath 23 that are covered in sequence, and the first main body 11 and the second main body 21 are provided with eight working channel 3. A hollow structure 112 is provided inside the first body 11 , and the hollow structure 112 is located in a solid area between a plurality of working channels 3 . The concrete structure of hollow structure 112 can be as follows Figure 6 or Figure 7 shown.

[0065] like Figure 8 As shown, in some special usage occasions, other areas of the working channel 3 can be completely cut off from the first m...

Abstract

The invention discloses an endoscope structure which comprises an operation part, a passive bending part and an active bending part which are connected in sequence, the operation part can drive the active bending part to bend, and the active bending part comprises a first main body, a first outer braid and a first outer skin which are wrapped in sequence. The passive bending part comprises a second main body, a second external braid and a second sheath which are sequentially wrapped, a plurality of working channels are arranged in the first main body and the second main body, and the rigidity of the first main body is smaller than that of the second main body; and / or; the rigidity of the first outer braid is smaller than that of the second main body; and / or the rigidity of the first outer skin is smaller than that of the second outer skin. An internal channel of the endoscope structure is large, the outer diameter is small, and the flexibility of the active bending part is high.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscope structure. Background technique [0002] In recent years, endoscopes have been widely used in medical and industrial fields. By operating the operating part of the endoscope, the bending part inserted into the space to be inspected can be bent in multiple directions, thereby adjusting the position or posture of the imaging device so that the area to be inspected can be observed better. [0003] The part inserted into the human body includes a head end, an active bending part that can actively control its bending, and a passive bending part that can passively bend following the shape of the inspected area. The active bending part is mainly composed of snake bones, internal pipelines and other components, and the passive bending part is mainly composed of insertion tubes, internal pipelines and other components. [0004] In order to reduce the pain of the p...
