The present invention is in the field of endoscopes, and more particularly relates to improvements in the steerable structure of the front end of an endoscope device.

At present, the conventional endoscope device is mostly made up of a photographic module, a light-emitting element and a hollow tube. After that, after displaying the screen on itself or externally, the image inside the target object can be displayed, for example, the endoscope device for medical use is used to view the tissue inside the living body, or the endoscope device for industrial use is used for viewing. The internal structure of a general object (mechanical, vehicle), at this time, the operator can detect whether the target object is abnormal.

However, the steering mechanism of the endoscope device of the prior art has a plurality of hollow metal, and the hollow metal has a riveting hole corresponding to the rivet, so that the metal structure can be steered, so it is required to have a relatively high precision, and the complicated process is assembled.

The first protruding tooth 311 and the second protruding tooth 312 There is a first tooth groove 314 between the first convex tooth 311 and the third convex tooth 313. The first tooth groove 314 and the root tooth 316 of the bottom of the second tooth groove 315 are pressed against each other. The lower half of the line 21. The second hollow gear 32 is adjacent to the first hollow gear 31, and the second hollow gear 32 has a fourth convex tooth 321 and a fourth convex tooth 322 and a sixth convex adjacent to the left and right of the fourth convex tooth 321 tooth 323, a fourth tooth groove 324 is defined between the fourth convex tooth 321 and the fifth convex tooth 322, and a fourth tooth groove 325, a third tooth groove 324 and a fourth portion are disposed between the fourth convex tooth 321 and the sixth convex tooth 323. The root 326 at the bottom of the slot 325 is pressed against the wire halves 22.

As described above, the naturally formed slots 314, 315, 324, 325 between the two tooth roots 316, 326 of the hollow gears 31, 32 can be used to mount the two pull wires 2, and then by the adjacent two hollow gears. 31 and 32 are arranged adjacent to each other, so that the two tooth roots 316 and 326 of the hollow gears 31 and 32 can be pressed inwardly against the pull wire and the lower half 21 and 22 to achieve the positioning and easy steering of the cable 2, and can be utilized. The roots 316 and 326 of the groove are naturally formed between the convex teeth and the convex teeth of the hollow gears 31 and 32, and the plurality of pull wires 2 and the transmission line can be disposed.

Specifically, the root of the bottom of each of the slots is lower than the center of the hollow gear, so that the gear and the adjacent gear have the same structural body (the adjacent gear only needs to be turned to make the first hollow gear 31 A slot 314 and a second slot 315 are opposite to the third slot 324 and the fourth slot 325 of the second hollow gear 32, so as to reach the lower half 21 of the cable that is pressed against the cable 2 and Pull the wire half 22 or the transmission line to achieve the positioning and easy steering of the cable 2. Each of the special gears is lower than the center of the hollow gear, and is spaced apart from the general gear, so that the same gears 31, 32 can be connected to each other to form a steering module 3. The front end of the rib 33 is integrally connected to the first hollow gear 31, and the rear end thereof is integrally connected to the second hollow gear 32. The curved rib 33 has a short surface 331 and a long surface 332. The curved rib 33 The long face 332 is bent in both clockwise and counterclockwise directions, as shown in Figures 5 and 6.

The second protruding tooth 312 is opposite to the first protruding tooth 311 and clockwise to the outer edge of the third protruding tooth 313 is a circular arc body 317, wherein the fifth protruding tooth 322 is reversed to the fourth protruding tooth 321 And the outer edge of the sixth protruding tooth 323 is a circular arc body 317 counterclockwise. When one of the pulling wires 2 is pulled, the bending rib 33 is bent clockwise or counterclockwise in one direction, by the first hollow The circular arc bodies 317 of the outer edge of the gear 31 interfere with each other by the circular arc body 317 of the outer edge of the second hollow gear 32 to limit the angle at which the ribs 33 are bent. As described above, the outer edges of the two adjacent hollow gears 31, 32 interfere with each other, so that the steering structure of the endoscope device does not cause any steering and excessive steering angle.

The lens module 40 has a double-half-shaped rib 401 which is defined by a circular hollow base 402 extending outwardly from the outer edge. The half-moon rib 401 and the circular hollow base 402 are defined as a hollow accommodating space 41. The outer edge of the double-half-shaped rib 401 occupies 1/1.5 (2 π r)~1/6 (2 π r) of the outer edge of the circular hollow base 402, wherein the circular hollow base 402 has two The wire passes through the opening 403 so that the wire 2 can be additionally fixed by the potting body 42 after passing through the wire. The image housing module 43 has an image sensor 431, a lens 432 and an LED 44. The LED 44 is mounted on the L-shaped LED positioning seat 406.

The lens module 40 further has a hollow passage 44. The hollow passage 44 disposed in the hollow portion of the lens module 40 extends from the hollow portion of the steering module 3 to the hollow portion of the detecting flexible tube 5 for gas/liquid transmission or for components. Crossing.

A recess 404 is formed between the half-moon rib 401 and the half-moon rib 401. An opening 405 is formed between the front end of the half-moon rib 401 and the front end of the half-moon rib 401 for receiving the front. The image, and the receiving space 404 formed between the two halves of the rib 401, can slightly increase the accommodating space of the hollow accommodating space 41, when the image sensor 431, a lens 432 and an LED are placed When placed in the hollow accommodating space 41, if the image sensor 431, the lens When the outer diameter of the components such as the 432 and the LED is too large, the space of the image sensor 431, the lens 432 and the LED 45 can be accommodated by the space of the placing port 404, and then filled and sealed by the potting body 42. The remaining space of the accommodating space 41 allows the heat transfer of the potting body 42 to achieve the effect of dissipating heat.

The filling body 42 is infused into the hollow receiving space 41 by an opening 405 formed between the front end of the half-moon shaped rib 401 and the front end of the half-moon shaped rib 401, and the hollow receiving space 41 is formed by the half moon convex The rib 401 and the circular hollow base 402 are defined.
