Description

Turntable for endoscope steering control device

The invention relates to a steering device for an endoscope, and more particularly to a carousel for an endoscope steering device.

Referring to the U.S. Patent No. 6,702,737, the general endoscope includes a lens, a steering device, and a tube connecting the lens and the steering device. The tube body is provided with a rope and a bend close to the lens. a folding structure that bends the rope and the section of the tube that is close to the lens by the steering control device, thereby changing the direction in which the lens is photographed.

In detail, the steering control device includes a turntable, the middle portion of the rope is wound around the turntable, and the two ends of the rope are connected to two opposite sides of the lens (for example, the left side and the right side), so the rope has two Extending from the turntable and extending to the connecting section of the lens, by rotating the turntable, one of the connecting sections can be shortened while the other connecting section is enlarged, thereby making the lens facing the shortened connecting section Turn in the direction (for example, left or right).

However, in order to enable the turntable to smoothly control the rope and to prevent the rope from slipping, the shape of the conventional turntable and the manner in which the rope is disposed are complicated to design and thus still need to be improved.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a turntable for an endoscope steering control device, which has a shape and a manner of setting a rope. It is simple, and at the same time, it can achieve smooth control of the rope and avoid the rope slipping.

In order to achieve the above object, the turntable of the endoscope steering control device provided by the present invention comprises a body, and the top and the bottom of the body respectively have a recess from the top to the bottom and a recess from the bottom to the bottom. a horizontal plate is disposed between the upper groove and the lower groove, the horizontal plate has a first perforation communicating with the upper groove and the lower groove, and the upper groove and the lower groove respectively The utility model has an upper sidewall and a lower sidewall, the upper sidewall having a second through hole communicating with the upper groove, the lower sidewall having a third through hole communicating with the lower groove.

Thereby, the shape of the turntable and the way of setting the rope are simpler than those of the conventional one, and at the same time, the smooth control of the rope and the avoidance of the rope slip can be achieved.

The detailed construction, features, assembly or use of the turntable of the endoscope steering steering device provided by the present invention will be described in the detailed description of the subsequent embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

The technical content and features of the present invention will be described in detail below with reference to the accompanying drawings, in which: FIG. 1 is a turntable of an endoscope steering control device provided by a preferred embodiment of the present invention. a three-dimensional combination with a rope; The second figure is a front view of the turntable of the endoscope steering control device provided by the preferred embodiment of the present invention; the third figure is the rear of the turntable of the endoscope steering control device provided by the preferred embodiment of the present invention. The fourth view is a top view of the turntable of the endoscope steering control device provided by the preferred embodiment of the present invention; and the fifth figure is the turntable of the endoscope steering control device provided by the preferred embodiment of the present invention. FIG. 6 is a perspective view showing a combination of a turntable and a rope of an endoscope steering control device according to the preferred embodiment of the present invention, respectively showing a different viewing angle from the first image; 7 is a cross-sectional view along the line 8-8; and the ninth and tenth views are similar to the eighth figure, but showing the turntable of the endoscope steering control device provided by the preferred embodiment of the present invention. The other two design aspects of a first perforation.

Please refer to the first figure. The first figure shows a turntable 10 of an endoscope steering control device according to a preferred embodiment of the present invention, and a rope 20 disposed on the turntable 10.

In the present embodiment, the turntable 10 includes a body 30 having a disk shape, and a tubular body 40 integrally extending upward from the center of the body 30. However, the turntable 10 may also not have the tubular body 40.

Referring to the second to fifth figures, the top of the body 30 of the turntable 10 has a recess 34 above and below the recess, and the bottom of the body 30 has a recess 35 from the bottom to the bottom, the body 30 More has a side surface 33, And an upper groove 36 and a lower groove 37 recessed from the side peripheral surface 33. There is a transverse plate 38 between the upper and lower grooves 34, 35. The horizontal plate 38 has a first through hole 382 communicating with the upper and lower grooves 34, 35. The upper groove 34 and the lower groove 35 respectively have an upper sidewall 341 and a lower sidewall 351. The upper sidewall 341 has a second through hole 342 communicating with the upper groove 36 and the upper groove 34. The lower sidewall 351 There is a third through hole 352 that connects the lower groove 37 and the lower groove 35.

As shown in the fourth figure, the line L1 of the center of the second through hole 342 and the center of the turntable 10 and the line L2 of the center of the third hole 352 and the center of the turntable 10 have an angle θ ₁ of 180 degrees. The line L3 of the center of a through hole 382 and the center of the turntable 10 and the line L1 have an angle θ ₂ of 90 degrees, that is, the angle θ ₃ between the line L3 and the line L2 is also 90 degrees. The positional arrangement of the aforementioned through holes 382, 342, and 352 is a preferred design, but is not limited thereto.

Referring to the first, sixth and seventh figures, the rope 20 is sequentially wound around the lower side wall 351, passes through the third through hole 352, passes through the first through hole 382, and passes through the second The through hole 342 is disposed around the upper side wall 341. Therefore, the rope 20 can be sequentially divided into a first section 21 extending from the lower groove 37 and a second section 22 located in the lower groove 37. a third section 23 located in the lower recess 35, a fourth section 24 located in the upper recess 34, a fifth section 25 located in the upper trench 36, and a trench from the upper trench The sixth section 26 of the slot 36 extends. The turntable 10 can be regarded as being divided into a front half 11 and a rear half 12 (as shown in the seventh figure) by the second through hole 342 and the third through hole 352. In the front half portion 11, the second section 22 of the rope 20 wound around the lower side wall 351 and the fifth section 25 wound around the upper side wall 341 are located in the rear half portion 12.

Compared with the conventional endoscope mirror and the way of setting the rope, the shape of the turntable 10 and the rope 20 provided by the present invention are relatively simple, and the rope 20 is wound around the turntable 10. The state allows the turntable 10 to smoothly control the rope 20 and prevent the rope 20 from slipping.

It is worth mentioning that the first through hole 382 of the turntable 10 can vertically penetrate the horizontal plate 38 (as shown in the eighth figure); or the first through hole 382 can be directed from the top to the bottom of the third through hole 352 Tilting (as shown in FIG. 9) causes the cord 20 to move smoothly within the first perforation 382; alternatively, the first perforation 382 can also be inclined from top to bottom toward the second perforation 342 such that the The rope 20 is less prone to slipping.

Finally, it is to be noted that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention, and alternative or variations of other equivalent elements should also be the scope of the patent application of the present application.
