Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and specifically refers to a control part and an endoscope thereof. Background Art

[0002] An endoscope is a precision medical instrument composed of systems such as an image sensor, an optical lens, a light source illumination, and a water and gas control. It enters the human body cavity through natural orifices such as the oral cavity or small incisions made during surgery for observation and treatment. When in use, the endoscope is introduced into the organ to be examined, and the changes of the relevant organs or parts can be directly observed. With the help of the endoscope, doctors can see lesions that cannot be shown by other medical devices such as X-rays, greatly improving the diagnostic ability. Therefore, the accuracy and convenience of controlling the snake bone part in the endoscope are the keys to the use of the endoscope.

[0003] [[ID=eleven]]Currently, there are various types of endoscopes, which can be divided into anoscope, esophageal endoscope, etc. according to the application site to observe the corresponding parts of the human body. Generally speaking, the existing endoscopes mainly include two control modes. One is only to support two-way bending control. The front end of the snake bone is controlled by the handle to realize bending in two directions. However, due to the limitation of the wide angle of the image sensor, it is impossible to directly observe the tissue in all directions of 360°. When the target part is not within the viewing range, the operator needs to manually twist the handle part to adjust the angle of the front end of the snake bone to achieve it. Therefore, the disadvantage of the two-way bending control mode is that the angle torsion direction is not clear, the operation is cumbersome, not intuitive, and not convenient.

[0043] The following describes embodiments of the present application in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0045] The present invention will be described in further detail below in conjunction with the full text.

[0046] Combined with attachment Figures 1 - 15 , the endoscope and the control unit provided by the embodiment of the present invention are described. An endoscope, such as Figure 1 and Figure 2As shown in the figure, the endoscope includes a handle and a snake bone assembly. A control unit is installed inside the handle. The control unit is used to control the snake bone assembly at the front end of the endoscope to observe omnidirectionally at 360° under pitch and left-right deflection. The control unit includes multiple groups of traction ropes 4 and operation devices 3 arranged in a mirror image.

[0047] When the present invention is specifically implemented, as Figures 1 - 3 shown in the figure, the snake bone assembly includes three sections of adjustable snake bones connected in sequence. The snake bone body 1 includes a protective hose 101 and a connecting block 102 inside the protective hose 101. Multiple groups of airbag columns 103 are installed at the upper end of the protective hose 101, and the airbag columns 103 connect two adjacent protective hoses 101. Elastic cloth 104 is installed between multiple groups of airbag columns 103 and at both ends of the two protective hoses 101. The elastic cloth 104, the protective hose 101, and the airbag columns 103 play a role in supporting the snake bone assembly. And during adjustment, because they are all elastic or gaseous, they can move in multiple directions or at multiple angles. A lengthening hose is connected between the snake bone assembly and the handle. The lengthening hose is connected in the middle. The lengthening hose is a prior art and will not be elaborated here. The circuit is connected inside the snake bone assembly through the lengthening hose. Universal holes for cooperating with the circuit are opened on the connecting block 102. The upper end of the airbag column 103 of the snake bone body 1 of the first section is connected with a guard plate, and the guard plate is installed with observation elements such as a camera. This is a prior art. After being inserted into the human body and the endoscope is introduced into the organ to be examined, the changes of the relevant organ or part can be directly observed.

[0048] When the present invention is specifically implemented, as Figure 2 and Figure 3 shown in the figure, each of the three sections of adjustable snake bones includes a snake bone body 1, and an angle adjustment device 2 is installed inside each snake bone body 1. The angle adjustment device 2 includes a support hose 201, a first movable half-ring 202, and a second movable half-ring 203. The support hose 201 is connected to the corresponding connecting block 102. The support hose 201 of the snake bone body 1 of the first section is connected to the guard plate.

[0049] Specifically, the first movable semi-ring 202 and the second movable semi-ring 203 are slidably mounted on the connecting block 102. Connecting rods 204 are hinged to both ends of the first movable semi-ring 202 and the second movable semi-ring 203, and the other ends of the connecting rods 204 are connected to the support hose 201. The first movable semi-ring 202 and the second movable semi-ring 203 are arranged in a crosswise and staggered manner. Slide holes 105 for the first movable semi-ring 202 and the second movable semi-ring 203 to slide are formed in the connecting block 102. The first movable semi-ring 202 and the second movable semi-ring 203 can move in the slide holes 105 under the action of an external force, so as to drive the corresponding snake bone body 1 to adjust the angle. Two traction ropes 4 in each group are respectively connected to one side of the two corresponding connecting rods 204, and the other ends of the traction ropes 4 are connected to the first rotating wheel 301, the second rotating wheel 302 or the third rotating wheel 303. There are 6 traction ropes 4, which are divided into three groups. Specifically, the two traction ropes 4 in each group are connected to one side of the two connecting rods 204 of the corresponding adjusting device 2, and the other ends of the two traction ropes 4 are respectively connected to the first rotating wheel 301, the second rotating wheel 302 or the third rotating wheel 303 of the two operating devices 3. The three adjusting devices 2, the three groups of traction ropes 4 and the two first rotating wheels 301, the second rotating wheel 302 and the third rotating wheel 303 in the two operating devices 3 correspond one by one.

[0050] Specifically, the traction rope 4 is made of an elastic rope, and the traction rope 4 plays a role in stretching and supporting.

[0051] When the present invention is specifically implemented, such as Figure 3 、 Figure 5 and Figure 7As shown, the traction rope 4 is used to connect the adjustment device 2 and the two operating devices 3. The two operating devices 3 include a handle, a connecting tube 6 in the handle, and a first rotating wheel 301, a second rotating wheel 302 and a third rotating wheel 303 that are rotatable outside the connecting tube 6 and connected to the traction rope 4. A rotating rod 7 for driving the first rotating wheel 301 to rotate is installed in the connecting tube 6. The connecting tube 6 includes a fixed tube 601 fixedly connected to the handle, a rotating tube 602 connected to the handle by a bearing, and a linkage tube 603. Specifically, the fixed tube 601, the rotating tube 602 and the linkage tube 603 are coaxially arranged. The linkage tube 603 is arranged between the fixed tube 601 and the rotating tube 602, and a gap is left between them. The first rotating wheel 301 is fixedly connected to the outside of the rotating tube 602. A limiting tube 10 is installed inside the second rotating wheel 302 and the third rotating wheel 303. The second rotating wheel 302 is installed between the rotating tube 602 and the connecting tube 603 via the limiting tube 10 and a bearing. The third rotating wheel 303 is installed between the fixed tube 601 and the connecting tube 603 via the limiting tube 10 and a bearing. One end of the rotating rod 7 is connected to the first rotating wheel 301 to drive the rotating tube 602 to rotate. The second rotating wheel 302 and the third rotating wheel 303 are connected to the outside of the connecting tube 6 via two limiting tubes 10 and four bearings. This can achieve independent rotation of the first rotating wheel 301, the second rotating wheel 302, or the third rotating wheel 303. One end of the rotating rod 7 is connected to the rotating tube 602, which is connected to the handle via a bearing. Rotation of the rotating rod 7 can drive the third rotating wheel 303 outside the rotating tube 602 to rotate, thereby driving the traction rope 4 to move.

[0052] The function of the connecting pipe 6 of the present invention is:

[0053] 1: Connect the first rotating wheel 301, the second rotating wheel 302 and the third rotating wheel 303, and realize a coaxial arrangement;

[0054] 2: Through the bearing and the connecting tube 6, the first rotating wheel 301, the second rotating wheel 302 and the third rotating wheel 303 can rotate independently, which provides a favorable operating space for the subsequent control of the snake bone assembly at the front end of the endoscope and 360° all-round observation under pitch and left and right deflection.

[0055] When the present invention is specifically implemented, Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 12As shown in the figure, a driving device 8 for driving the first rotating wheel 301 or the second rotating wheel 302 or the second rotating wheel 302 and the third rotating wheel 303 to rotate simultaneously is also installed in the connecting pipe 6. The driving device 8 includes a sliding pipe 801 between the rotating rod 7 and the connecting pipe 6, and a limiting block 802 slidably connected to the outer side of the sliding pipe 801. A fixed disk 803 is installed on the outer side of the sliding pipe 801 and between the two limiting blocks 802. A plurality of groups of limiting rods 804 are installed at both ends of the fixed disk 803, and the limiting rods 804 penetrate through the limiting blocks 802. A first adjusting spring 805 and a second adjusting spring 806 are installed on the outer side of the limiting rods 804 and between the two limiting blocks 802. A groove is formed in the inner part of the outer side of the limiting block 802, and a elastic sheet 807 is installed in the groove. A clamping groove 11 for cooperating with the elastic sheet 807 is formed on the inner wall of the limiting pipe 10. A sliding hole for cooperating with the sliding pipe 801 and the limiting rod 804 to slide is formed on the limiting block 802.

[0056] In the specific implementation of the present invention, the elastic forces of the first adjusting spring 805 and the second adjusting spring 806 are different, and the stretching force of the first adjusting spring 805 is greater than the stretching force of the second adjusting spring 806. That is, when the fixed disk 803 moves to the left, the second adjusting spring 806 is compressed, and the first adjusting spring 805 is stretched. And the first adjusting spring 805 will drive the adjacent limiting block 802 to move. At this time, the second adjusting spring 806 is still in a compressed state and cannot push the adjacent limiting block 802 of the second adjusting spring 806 to move (at this time, the elastic sheet 807 is greater than the compression force of the second adjusting spring 806). The elastic sheet 807 on the limiting block 802 adjacent to the first adjusting spring 805 will move and be stuck in the clamping groove 11, so that the driving device 8 is connected to the second rotating wheel 302, as Figure 11 shown;

[0057] When the fixed disk 803 is continuously pulled to move to the left, the first adjusting spring 805 expands. Because the elastic sheet 807 on the adjacent limiting block 802 is stuck in the clamping groove 11 to generate resistance, the fixed disk 803 will push the second adjusting spring 806 to move, so that the elastic sheet 807 on the limiting block 802 adjacent to the second adjusting spring 806 is stuck in the clamping groove 11, realizing that the driving device 8 is connected to the third rotating wheel 303 and the second rotating wheel 302, as Figure 12 shown.

[0058] In the specific implementation of the present invention, one end of the elastic sheet 807 is connected to the clamping groove 11, and the other movable end is movably connected in the connecting pipe 6. The elastic sheet 807 is in a ">" structure, and the opening faces outward.

[0059] When the drive device 8 is connected to the third rotating wheel 303 and the second rotating wheel 302, the sliding tube 801 moves inward, driving the fixed disk 803 to move inward. Because the elastic forces of the first adjusting spring 805 and the second adjusting spring 806 are different, it will first push the limiting block 802 adjacent to the first adjusting spring 805 or the second adjusting spring 806 to move into the connecting tube 6. Continuing to move will drive the two limiting blocks 802 to move into the connecting tube 6, and the unlocking is completed, realizing that the drive device 8 is not connected to the third rotating wheel 303 and the second rotating wheel 302, as Figure 10 shown.

[0060] When the present invention is designed, the rotation of the sliding tube 801 of the drive device 8 will drive the rotation of one or both combinations of the third rotating wheel 303 and the second rotating wheel 302. When driving the rotation of one of the third rotating wheel 303 or the second rotating wheel 302, the upper end of the elastic piece 807 on one of the limiting blocks 802 is located in the connecting tube 6, realizing resistance rotation. When the doctor rotates and adjusts, the resistance is increased, and fine adjustment can be performed. Compared with the adjustment without resistance, a little adjustment can be completed, which is convenient for finding the lesion location of the organ.

[0061] When the present invention is specifically implemented, as Figure 7 , Figure 9 , Figure 13 shown, a coaxial rotating device 9 for realizing interlocking between the rotating rod 7 and the drive device 8 is further installed in the connecting tube 6. The coaxial rotating device 9 includes a moving rod 901 slidably connected in the rotating rod 7 and support blocks 902 arranged on both sides of one end of the moving rod 901, and the support blocks 902 extend into the connecting tube 6. A sliding groove 903 for cooperating with the support blocks 902 is formed on the rotating rod 7. An automatically retractable clamping arm 904 is hinged on the outside of the support block 902. Specifically, the clamping arm 904 can be automatically retracted through a torsion spring. A rotating hole is formed in the clamping arm 904, and a fixed shaft is provided on the support block 902. The clamping arm 904 is arranged outside the fixed shaft through the rotating hole, and a torsion spring is installed between the rotating hole and the fixed shaft. One end of the torsion spring is fixedly connected to the fixed shaft, and the other end is connected to the inner wall of the rotating hole, completing the automatic retraction of the clamping arm 904 through the torsion spring. A clamping block 905 is installed in the clamping arm 904. A clamping disk 12 for cooperating is installed at one end of a plurality of limiting rods 804 close to the clamping arm 904. A limiting groove 13 for cooperating with the clamping block 905 is formed on the outside of the clamping disk 12. When the moving rod 901 moves, the support block 902 can move in the sliding groove 903, and the clamping arm 904 approaches or moves away from the clamping disk 12, completing the clamping of the clamping block 905 in the limiting groove 13 (locking state), as Figure 13 shown, or moving away from the clamping disk 12 (unlocking state), as Figure 10 shown.

[0062] The locking state realizes the linkage between the third rotating wheel 303 or the second rotating wheel 302 and the first rotating wheel 301.

[0063] The unlocked state is that the third rotating wheel 303 or the second rotating wheel 302 is disconnected from the first rotating wheel 301.

[0064] When the present invention is specifically implemented, such as Figure 5 , Figure 6 , Figure 14 and Figure 15 as shown, a linkage mechanism 5 for realizing linkage is installed between two operating devices 3. The linkage mechanism 5 includes a stepping bolt 501 threadedly connected to a handle and a return frame 502. A linkage rod 503 is installed on the inner bearing of the return frame 502. Blocks 504 are installed at both ends of the linkage rod 503. Locking grooves 14 for cooperating with the blocks 504 to press downward and lock are provided on the opposite surfaces of two rotating tubes 602. A sphere 505 is installed at the lower end of the stepping bolt 501. An activity groove is opened at the upper end of the return frame 502 and the sphere 505 is located in the activity groove. The block 504 is of a polygonal structure, and the locking groove 14 is used in cooperation with the block 504. When the block 504 moves downward close to the locking groove 14, the block 504 is stuck in the locking groove 14. Because of the polygon, locking can be realized. Specifically, the block 504 and the linkage rod 503 are eccentrically arranged. When the block 504 moves downward close to the locking groove 14 to realize locking, the linkage rod 503 and the connecting tube 6 are coaxial, and the third rotating wheel 303, the second rotating wheel 302, and the first rotating wheel 301 on two connecting tubes 6 can be rotated simultaneously.

[0065] When the present invention is specifically implemented, a rotating disk can be arranged on the outer sides of the third rotating wheel 303, the second rotating wheel 302, and the first rotating wheel 301. A rotating groove for cooperating with the rotating disk is opened on the handle. The rotating disk is located in the rotating groove, and rotation can be realized. Moreover, a rotating handle for rotation or pulling is provided at the end of the moving rod 901, the sliding tube 801, and the rotating rod away from the handle, so that quick operation can be achieved.

[0066] The present invention realizes two groups of adjustment modes through the linkage mechanism 5:

[0067] 1. The linkage mechanism 5 can realize the linkage of the first rotating wheel 301, the second rotating wheel 302, or the third rotating wheel 303 of two operating devices 3. When linking, the two traction ropes 4 of the adjusting device 2 can work simultaneously. As Figure 3 and Figure 4 shown, the traction rope 4 is stressed to pull the connecting rod 204 to articulate and rotate. The second movable half ring 203 slides and adjusts in the sliding hole 105, and drives a single snake bone body 1 to adjust through the support hose 201. Similarly, the three snake bone bodies 1 can be adjusted separately or jointly.

[0068] 2. When the linkage mechanism 5 is not working, the first rotating wheel 301, the second rotating wheel 302, or the third rotating wheel 303 of the two operating devices 3 can work independently, enabling the two traction ropes 4 of the adjusting device 2 to work independently. For example, Figure 3 and Figure 4 as shown, when one traction rope 4 is stressed and pulls the connecting rod 204 to rotate, the first movable half-ring 202 slides and adjusts within the sliding hole 105, and the connecting rod 204 on the second movable half-ring 203 rotates and adjusts through hinge connection, driving the single snake bone body 1 to rotate through the support hose 201. Similarly, the three snake bone bodies 1 can be adjusted individually or jointly.

[0069] In summary, through the linkage mechanism 5, the linkage of the two operating devices 3 can be achieved, and the adjusting device 2 can thereby change the downward or left-right adjustment of a single or multiple snake bone bodies 1.

[0070] In the specific implementation of the present invention, the mirror-image arranged operating devices 3 achieve the simultaneous or independent rotation of the first rotating wheel 301, the second rotating wheel 302, and the third rotating wheel 303 through the linkage among the linkage mechanism 5, the driving device 8, and the rotating rod 7.

[0071] Specifically, the linkage mode of a single operating device is as shown in the following table: <(

[0072]

[0073] In summary, there are 7 linkage modes for a single operating device. Through the linkage mechanism 5, the linkage of the two operating devices 3 can be achieved, and the combination of the two 7 - mode linkages results in a total of 49 adjustment modes, effectively realizing the individual or multiple adjustment operations of the three snake bone bodies 1, controlling the snake bone assembly that pitches and deflects left and right, the rotation direction within the 360° range in the X / Y plane, and the size of the snake bone bending angle, flexibly searching for the target, and quickly and accurately pointing to the organ or changing part to be peeped.

[0074] The control part of the embodiment of the present application not only solves the problems of the two - way bending control mode, such as unclear angle - twisting direction, cumbersome, unintuitive, and inconvenient operation, but also reduces the production cost of the endoscope handle, reduces the economic burden on patients who need to use the endoscope, and also reduces the space occupied by the control part in the axial direction of the endoscope handle, which is beneficial to the miniaturization development of the split - type endoscope handle; meanwhile, such a concise and ingenious design method makes the assembly of the endoscope handle easy, which is beneficial to improving the production efficiency of the endoscope handle.

[0075] The embodiment of the present application also provides an endoscope, including the aforementioned control part.

[0076] The above description of the present invention and its embodiments is not restrictive. What is shown throughout the text is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to the technical solution without creative efforts, they shall fall within the protection scope of the present invention.
