Problems solved by technology

The intestinal endoscope is provided with the internal diameter of the through hole connected to the fixed rod equal to the external diameter of the hose, which is convenient for the hose to penetrate through the through hole connected to the fixed rod; the above-mentioned technology is driven by an external connection, and the flexibility Insufficient, and the endoscopic lens is prone to fogging during inspection, resulting in low inspection efficiency and poor pathological accuracy

Embodiment 1

[0046] Such as figure 1 As shown, an anti-fog type anorectal endoscope; including a housing 1; the housing 1 is made of a transparent material, the housing 1 is arranged as a capsule structure, and the inside of the housing 1 is in a hollow state, and the housing One end of the body 1 is provided with a camera lens 2, and the camera lens 2 is embedded in the housing 1, and at least one heating element 3 is provided at the end of the housing 1 close to the camera lens 2, and the heating element 3 is arranged on a fixed On the plate 16, the fixed plate 16 is fixed inside the housing 1, and the center position of the side of the fixed plate 16 away from the heating element 3 is provided with a lens 6, and the lens 6 is on the same level as the camera lens 2, And the center of the camera lens 2 coincides with the center of the lens 6; both sides of the lens 6 are provided with lighting lamps 7; Signal connection, the image processing module 8 receives and processes the image info...

Embodiment 2

[0050] On the basis of Example 1, as Figure 2-4 As shown, when performing an endoscopic inspection, the endoscope is sent into the anorectum, and the permanent magnet 4 arranged inside the endoscope is driven by an external external magnetic field 13, which does not consume an internal power source, which is beneficial to reduce the size of the endoscope. The volume of the external magnetic field 13 adopts two groups of Helmholtz coils, and currents of different intensities are passed through, and after the currents form a certain phase relationship, a rotating magnetic field 15 is generated in a large space range, thereby driving the endoscope The internal permanent magnet 4 moves; the permanent magnet 4 is radially magnetized, and the external magnetic field is formed. The direction of the magnetic force line of the space magnetic field pointed by the permanent magnet 4, along with the change of the current harmonic in the Helmholtz coil, generates a rotating magnetic field ...

Embodiment 3

[0052] Such as Figure 5-7 As shown, on the basis of Embodiment 1, the anti-fog type anorectal endoscope adopts an anti-fog temperature control system, which is characterized in that the anti-fog temperature system includes a control module, a temperature module, and a communication module The control module includes a controller 10 and a control circuit, the temperature module includes a temperature acquisition module and a temperature control module, the temperature acquisition module collects the temperature of the camera lens 2 and the temperature of the endoscope environment by setting a temperature sensor, and the temperature control module includes a heating The element 3 and the heating circuit, and the communication module realize the data transmission and recording of the system.

[0053] After the temperature acquisition module collects the surface temperature of the camera lens 2, it inputs the camera lens 2 surface temperature value to the controller 10; simultane...

Abstract

The invention discloses an anti-fog type anorectal endoscope. The anti-fog type anorectal endoscope comprises a shell; the shell is made of transparent materials, the shell is arranged to be of a bag structure, the interior of the shell is in a hollow state, a camera lens is arranged at one end of the shell, the camera lens is embedded in the shell, at least one heating element is arranged at the end, close to the camera lens, in the shell, and the heating elements are arranged on a fixed plate. The fixed plate is fixed in the shell, a lens is arranged at the center of the side, away from the heating element, of the fixed plate, the lens and the camera lens are located on the same horizontal plane, and the center of the camera lens coincides with the center of the lens; by arranging the anti-fog temperature control system and adopting a sectional type heating method, the camera lens of the endoscope is heated, the fogging problem of the endoscope is fundamentally solved, the imaging definition is improved, the examination efficiency is improved, and the focus examination accuracy is improved.

Description

technical field [0001] The invention belongs to the field of anorectal inspection instruments, in particular to an anti-fog type anorectal endoscope. Background technique [0002] The endoscope can observe the presence of rectal valves, ulcers, polyps, tumors, foreign bodies, etc., and observe whether there are internal openings such as fistulas, hemorrhoids, polyps, rectum, and tumors. [0003] However, when using an endoscope for inspection, since the endoscope is generally made of glass or resin, when the endoscope enters the human body, the water vapor in the body will liquefy when it encounters the lower-temperature endoscope camera lens. Water mist is generated, which affects the imaging clarity, causes blurred display, affects normal inspection, and cannot detect lesions in time and accurately. The inspection efficiency is low and the patient's comfort is poor. Twist the drive control, which will affect the movement posture during the inspection in the intestinal tra...
