Embodiment 1

[0068] A disposable medical endoscope, including an insertion assembly, a connecting part 5, a handwheel control part 6, such as Figure 1 ~ Figure 7 As shown, the insertion assembly includes a curved portion 2, a front end portion 1, a working channel 4, and a jacket 3 provided at the front end of the control portion, and the jacket 3 covers the curved portion 2;

[0069] The bending portion 2 is provided with a support assembly 21, which includes a proximal joint 211, an articulation ring set 212, and a distal joint 213. One end of the distal joint 213 is connected to the front end 1 and the other end is connected to the articulation ring set. 212. One end of the proximal joint 211 is connected to the hinge ring group 212, and the other end is connected to the endoscope control part,

[0070] One end of the working channel 4 is connected to the handwheel control portion, and the other end passes through the curved portion 2 to connect to the front end portion 1, and the outer jack...

Embodiment 2

[0079] The main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2. For the features that are not explained in this embodiment, the explanation in Embodiment 1 or Embodiment 2 is adopted, which will not be repeated here. The difference between this embodiment 1 and embodiment 2 is:

[0080] Such as figure 2 , image 3 As shown, the articulated ring group 212 includes a plurality of articulated rings 31, and the plurality of articulated rings 31 are articulated in pairs. Through a two-by-two articulated connection, all the articulated rings 31 are connected into a complete articulated ring group 212. Two first hinge ears 2121 are provided along the first radial direction at the upper end. The first hinge ears 2121 are hinged with the adjacent hinge ring 31. The lower end of the hinge ring 31 is provided with second hinge ears 2123 along the second radial direction. The hinge ear 2123 is hinged with the adjacent hinge ring 31, and t...

Embodiment 3

[0089] The main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2. For the features that are not explained in this embodiment, the explanation in Embodiment 1 or Embodiment 2 is adopted, which will not be repeated here. The difference between this embodiment 1 and embodiment 2 is:

[0090] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the first hinge ear 2121 is provided with a hinge shaft 2122, the second hinge ear 2123 is provided with a mounting groove, and the mounting groove includes a hinge hole 2124 and a guide hole. The hinge shaft 2124 is inserted into the mounting channel 2128 of the hinge hole 2124, the mounting channel 2128 is arranged vertically, and the entrance of the mounting channel 2128 is arranged at the top of the second hinge ear 2123. In this embodiment, the second hinge The hinge ear 2123 is arranged upside down, the top of which is the lowermost end of the secon...

Abstract

The invention provides a disposable medical endoscope. The disposable medical endoscope comprises a bending part, a connecting part and a hand wheel control part, the bending part comprises a near end connector, a hinging ring set and a far end connector, the hand wheel control part comprises a first hand wheel component, a second hand wheel component and a winding component which is used for driving a bending component, one end of a first control cable is arranged on the first control wheel in a winding mode, the other end of a first control cable is connected with the bending part, one end of a second control cable is arranged on a second control wheel in a winding mode, the other end of the second control cable is connected with the bending part, the first hand wheel component controls the first control wheel to move, and the second hand wheel component controls the second control wheel to move. Multiple hinging rings prepared through injection are mutually hinged, and through plastic change, the hinging rings are successfully installed in the mounting groove which is in an open type, so that every two hinging rings are hinged, two control cables are distributed and arranged on two control wheels in a winding mode, four directions can be controlled, through the control of the hand wheel control part, the bending angle is controllable, and the reliability is high.

Description

Technical field [0001] The invention belongs to the technical field of endoscopes, and in particular relates to a disposable medical endoscope. Background technique [0002] An endoscope is a commonly used medical device, which is composed of an insertion part, a bending part, and a front end provided at the front end of the operating part. The insertion part, the bending part and the front end are collectively called an insertion tube. It enters the human body through the natural orifice of the human body or through a small incision made by operation; when in use, the insertion tube of the endoscope is introduced into the organ for pre-examination, and the changes in the relevant part can be directly observed. [0003] Endoscope is a delicate medical device. Most of the domestic medical endoscope market is occupied by foreign products. The price ranges from tens of thousands to hundreds of thousands. It requires complicated and high-cost disinfection and maintenance after each use...
