Description

Technical Field

[0001] The present invention relates to the field of endoscopes, in particular to an insertion tube rotary endoscope. Background Art

[0002] Endoscopes are widely used in the medical field to diagnose pathological tissues within body cavities. Therefore, their inspection function is particularly important. Most existing endoscopes offer a 360° angle in four directions, enabling comprehensive inspection. However, existing endoscopes commonly suffer from the following issues: inconvenient scanning and inspection, blind spots, and poor image orientation.

[0003] Another common solution is to use an insertion tube with limited rotation. However, rotating the insertion tube relative to the gripper can cause the pull wires to become tangled, making it impossible to bend. Therefore, an insertion tube endoscope with unlimited 360° rotation is highly desirable in many applications. Summary of the Invention

[0036] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0037] like Figures 1 to 3 As shown, an insertion tube rotary endoscope provided according to the present invention includes a steering ring, a traction ring, a traction wire, a steering wire and a central rotating device, wherein: the traction ring is fixedly connected to the traction wire; the steering ring is fixedly connected to the steering wire; the traction ring and the steering ring are both arranged on the central rotating device, and the steering ring drives the traction ring to slide along the central rotating device; the traction ring, the traction wire and the central rotating device rotate synchronously, and the steering ring does not rotate synchronously with the central rotating device.

[0038] Furthermore, the traction ring and the control ring are coaxially arranged, the traction ring is arranged on the side where the control ring is connected to the control line, and the control ring is arranged on the side where the traction ring is connected to the traction line, ensuring that the control ring can drive the traction ring to move in the axial direction after receiving the pulling force of the control line.

[0039] In more detail, the insertion tube rotary endoscope also includes a sliding shaft. In this embodiment, two parallel sliding shafts are provided, distributed on the left and right sides of the operating ring. The operating ring is provided on the sliding shaft and can slide along the axial direction of the sliding shaft. Specifically, the operating ring can be in the form of a notch provided in the circumferential direction, or an accommodating opening extending outward in the circumferential direction. The function of the notch or the accommodating opening is, on the one hand, to cooperate with the sliding shaft limit, and on the other hand, to facilitate the passage of the operating ring. One end of the two parallel sliding shafts is fastened to an end cover. A through hole is provided on the end cover, and the operating wire passes through the through hole and is connected to the operating ring.

[0040] Furthermore, multiple control cables and control loops are provided, enabling two-way or four-way control. In this embodiment, two control cables are used as an example, with each cable connected to a corresponding control loop. When the control loop farther from the end cap is connected to a control cable, the cable passes through the control loop closer to the end cap and connects to the control loop farther from the end cap. The control loops may also be provided with wire rope mounting shafts, through which the control cables connect to the control loops.

[0041] In more detail, each operating ring is matched with a traction ring, and a traction line is set on the traction ring. When one of the operating rings moves according to the operating line, it will drive the traction ring corresponding to the operating ring to move.

[0042] The present invention further comprises a knob, which rotates synchronously with the central rotating device, and the traction line passes through the knob and is connected to the corresponding traction ring.

[0043] It should be noted that the control ring and the traction ring of the present invention can be replaced with each other.

[0044] In the present invention, the control line corresponds to the angle control mechanism connected to the fixed part, and the traction line passes through the main hose of the rotating part and corresponds to the snake bone connected to the front end of the main hose.

[0045] The central rotating device of the present invention is provided with a channel, and devices such as a signal conductive ring and a working channel can be coaxially arranged in the channel.

[0046] The present invention achieves a true 360° bend through the structural design of the control ring and the rotation ring. This structural advantage is superior to the traditional four-way combination 360° bend. It also enables unlimited rotation of the bend insertion tube, making inspections easier and facilitating human-machine interaction.
