Embodiment 1

[0027] like Figure 1 to Figure 4 , Figure 6 to Figure 10 As shown, the structure of the curved part of the speculum in the present invention includes a spring 1 and a bracket 2, and the cross section of the spring 1 is circular, fan-shaped, triangular, elliptical or a combination of the above-mentioned figures. In this embodiment, the spring 1 is a circular spring. The bracket 2 is connected to the coil of the spring 1, a coil connection point is formed at a certain position between the bracket 2 and the coil of the spring 1, and the bracket 2 defines any adjacent two spring coils. The distance between the connection points of the loops is constant, forming a channel 3 in said spring 1 . The channel can serve as a working channel. For the medical speculum, a separate working channel needs to be set up for inputting medical fluid or outputting body fluid, etc. A protective layer 4 is provided outside the curved portion structure, and the protective layer 4 is a plastic or...

Embodiment 2

[0036] like Figure 1 to Figure 10 As shown, in this embodiment, the speculum includes the above-mentioned bending part structure, and also includes a camera and an insertion tube 6, and one end of the bending part structure of the speculum is connected to one end of the insertion tube 6, and the channel 3 communicates with the passage in the insertion tube 6, and in the direction perpendicular to the plane formed by the two pillars 21, a curved traction is provided at the coil of the spring 1, and the curved traction It is steel wire or chemical fiber.

[0037] Further, the present invention also includes a tip part 5, the camera is arranged in the tip part 5, a first clamping groove is provided at the wire inlet end of the tip end part 5, and a first clamping groove is arranged at the wire outlet end of the insertion tube 6. A second clamping groove is provided, and the bending portion structure for the speculum is respectively connected with the tip end 5 and the insertion...

Abstract

The purpose of the present invention is to provide a simple and easy-to-manufacture curved portion structure for a speculum and a speculum including the curved portion structure for a speculum. The bending part structure for the speculum of the present invention includes a spring and a bracket, the bracket is connected to the coil of the spring, and a coil connection point is formed at a certain position of the bracket and the coil of the spring, so that The bracket defines the distance between any adjacent two spring coil connection points as a fixed value, and a channel is formed in the spring; the speculum also includes a camera and an insertion tube, and the speculum uses one end of the bending part structure It is connected with one end of the insertion tube, the channel is connected with the channel in the insertion tube, and in the direction perpendicular to the plane formed by the two pillars, a curved coil is provided at the coil of the spring Tractors, the curved tractors are steel wires or chemical fibers. The invention can be applied in the field of speculum devices.

Description

technical field [0001] The invention relates to a viewing device, in particular to a bending part structure for a speculum and a speculum including the bending part structure. Background technique [0002] There are many kinds of speculum, such as medical speculum, industrial speculum and police speculum. The speculum generally includes a tip part, an insertion tube and a bending part structure, and components such as a lens and a light source are arranged in the tip part, and the tip part can be controlled to bend and turn by using an angle steel wire passing through the insertion tube and the bending part structure. In the insertion tube, corresponding signal lines need to be set to input electric energy and light energy to the lens, light source and other devices, and output image signals to the outside. With the development of science and technology and the improvement of people's living standards, the requirements for the use of speculum and other products are getting ...
