[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This invention primarily aims to solve the problem that a fixed angle between the insertion part and the acquisition unit makes it impossible to guarantee that the image to be acquired is in the center position. In the following embodiments, "far end" refers to the side away from the operator, and "proximal end" refers to the side closer to the operator.

[0035] like Figures 1-11 As shown, the present invention discloses a multi-angle adjustable endoscope, including an adjustment handle and an image acquisition unit;

[0036] The adjustment handle includes;

[0037] The handle body 1 is round and hollow, designed for the operator to hold. The handle body 1 includes an upper handle cover 11 and a lower handle cover 12, which are connected and assembled by glue, snap-fit, or thread.

[0038] The insertion part 2 is a hard tubular structure, which is arranged at the distal end of the handle body 1, and is internally provided with a wire harness connected with the image acquisition unit and a snake bone adjustment traction rope.

[0039] The image acquisition unit includes a snake bone provided with four traction ropes, the proximal end of which is connected with the insertion part 2, and the distal end of which is provided with an image acquisition part.

[0040] The image acquisition unit includes an image acquisition part 3, the proximal end of which is provided with a connecting ball 31, the connecting ball 31 and the image acquisition part 3 are provided with a connecting waist 32 therebetween, the lower end of the connecting ball 31 is provided with a connecting mounting groove 33, and a plurality of connecting contacts 34 are arranged in the connecting mounting groove 33. In this way, the wiring can facilitate the adjustment of the angle of the image acquisition part 3 and is not affected by the wire harness.

[0041] The connecting contacts 34 are used for the connection between the image acquisition part 3 and the handle wire harness, and the connection mode can adopt welding or plug-in mode.

[0042] The connecting ball 31 is used for movably mounting at the front end of the insertion part 2, and the connection mode is a movable ball link. In this way, it is ensured that the image acquisition part 3 can be adjusted in angle relative to the front end of the insertion part 2.

[0043] The end face of the proximal end of the image acquisition part 3 is provided with four circumferentially distributed traction control wires 8. In this way, the traction control wire 8 can rotate the connecting ball 31 by applying a pulling force to a position of the image acquisition part 3, so as to adjust the angle.

[0044] In the embodiment, referring to Figures 5-6 , the connecting waist 32 is provided with an elastic washer, the upper and lower ends of the elastic washer are respectively in contact with the end face of the proximal end of the image acquisition part 3 and the insertion part 2. The elastic washer is used to keep the image acquisition part 3 concentric with the insertion part 2 when the image acquisition part 3 is not subjected to additional pulling force of the traction control wire 8. At the same time, the elastic washer can complete the automatic return after the angle adjustment of the image acquisition part 3 is completed by the supporting force of the elastic washer, and cancel the additional pulling force of the traction control wire 8. In this way, the problem of insufficient accuracy caused by the adjustment of the traction control wire 8 is avoided.

[0045] Further, the elastic washer is a rubber ring, or an elastic plastic provided with a gap slot.

[0046] In some embodiments, referring to Figure 5 , the elastic washer includes a plurality of first adjusting rings 4 and second adjusting rings 5 arranged in sequence and staggered.

[0047] The first adjusting ring 4 is generally flat and ring-shaped, with two circumferentially distributed first contact steps 42 at the bottom. The first adjusting ring 4 has four circumferentially distributed first through holes 41, and the first through hole 41 is located at the center of the first contact step 42.

[0048] The second adjusting ring 5 is generally flat and ring-shaped, with two circumferentially distributed second abutting steps 52 at the bottom; the second adjusting ring 5 is provided with four circumferentially distributed second through holes 51, and the second abutting step 52 is provided with a second through hole 51 at the center position;

[0049] The first adjusting ring 4 and the second adjusting ring 5 are concentrically arranged, the first abutting step 42 and the second abutting step 52 are staggered, and the first through hole 41 and the corresponding second through hole 51 are concentrically arranged.

[0050] Combination Figure 4 The traction control wire 8 passes through multiple first through holes 41 and second through holes 51 in sequence. With this design, the first adjusting ring 4 and the second adjusting ring 5 are used for support. Under normal circumstances, the four traction control wires 8 ensure the same tension, which can ensure the initial position of the image acquisition unit 3.

[0051] When angle adjustment is required, the traction control wire 8 applies tension to a position of the image acquisition unit 3, causing the connecting ball 31 to rotate, thereby adjusting the angle. The structure of the first adjusting ring 4 and the second adjusting ring 5 allows for clearance through rotation at the step, avoiding additional resistance during angle adjustment compared to an elastic rubber ring.

[0052] In this embodiment, see Figure 3 The handle body 1 is provided with an adjustment plate mounting bracket 115. The adjustment plate mounting bracket 115 is mounted on the inner wall of the handle body 1 by multiple support columns. The adjustment plate mounting bracket 115 is provided with a mounting ball head 1151.

[0053] Combined with appendix Figure 2 , 3 The handle body 1 is equipped with an adjustment disc 6, which includes a disc-shaped body 62. Four circumferentially distributed traction rope mounting points 63 are provided on the outer side of the disc-shaped body 62.

[0054] Combined with the appendix Figure 7 and 11 The center of the adjusting plate 6 is provided with a spherical mounting groove 61 for cooperating with the mounting ball head 1151. The mounting ball head 1151 is movably installed in the spherical mounting groove 61. This arrangement can ensure that the adjusting plate 6 can rotate freely with the mounting ball head 1151 as the center.

[0055] The side of the spherical mounting groove 61 close to the operator is connected with an adjusting rocker 9, which is arranged at the end of the handle body 1 close to the operator, and includes a connecting rod part 91 and a push disc part 92. The connecting rod part 91 protrudes out of the handle body 1 and is provided with the push disc part 92 for facilitating finger pushing.

[0056] In the specific implementation, one end of each of the four traction ropes for adjusting the snake bone is fixedly arranged on the traction rope mounting point 63, and the fixing can be achieved by welding or crimping. In use, the adjusting disc 6 is driven to swing around the mounting ball head 1151 by the movement of the adjusting rocker 9, so that the traction of the traction rope of the snake bone is completed, the posture of the snake bone is controlled, and meanwhile, the traction rope mounting point 63 is arranged in this way. Any angle adjustment will not cause the traction ropes arranged in two symmetrical directions to interfere with each other, so that full-angle adjustment can be achieved and the adjustment can be achieved only by the adjusting rocker 9.

[0057] For example, referring to Figure 11 When the adjusting rocker 9 swings upward according to the arrow in the figure, the front end 942 of the telescopic connecting rod 94 swings downward, the upper part of the adjusting disc 6 swings rightward according to the arrow, so as to drive the traction rope at this position to complete the pulling action, and thus drive the image acquisition functional part 35 of the image acquisition part 3 to rotate.

[0058] In one embodiment, referring to Figure 7 , the adjusting disc 6 is provided with a connecting groove 64 for movably connecting with the connecting rod part 91. The connecting rod part 91 and the connecting groove 64 are connected by threading or insertion, so that the detachable connection facilitates installation and processing. However, in this embodiment, the swinging direction of the adjusting rocker 9 and the rotating direction of the image acquisition functional part 35 of the image acquisition part 3 are opposite. Therefore, Figure 7 and Figure 11 are two different optional embodiments.

[0059] Referring to Figure 7 and Figure 11 , in the two different embodiments, the proximal end face of the handle body 1 is provided with a mounting hole, and two horizontally arranged elastic stabilizing rings 7 are arranged in the mounting hole. The connecting rod part 91 passes through the elastic stabilizing rings 7 and is installed. The elastic stabilizing rings 7 are installed to stabilize the initial position of the connecting rod part 91 under the condition that no external force is applied to the connecting rod part 91, so as to ensure that the connecting rod part 91 is concentric with the handle under the condition that no external force is applied to the connecting rod part 91. At this time, the snake bone is in a vertical state, and the endoscope is at zero angle. Meanwhile, there is a gap between the two elastic stabilizing rings 7, which can avoid excessive resistance when the connecting rod part 91 is adjusted. The elastic stabilizing rings 7 can be made of elastic rubber or plastic.

[0060] Referring to Figure 8The elastic stabilizing ring 7 is internally provided with a plurality of inner ring segments 71, and a plurality of elastic supporting columns 72 are arranged between the elastic stabilizing ring 7 and the inner ring segments 71, and the elastic supporting columns 72 are further arranged in an arc-shaped and inclined manner; thus, the connecting rod part 91 is supported, and the movement resistance of the connecting rod part 91 is avoided.

[0061] In some embodiments, referring to Figure 3 The handle body 1 is provided with an abutting adjusting table 111, the abutting adjusting table 111 is provided with four circumferentially distributed abutting through holes 112 for passing the traction ropes, and the abutting adjusting table 111 is provided with a guide disc 113 between the abutting adjusting table 111 and the adjusting disc 6.

[0062] The guide disc 113 is provided with four circumferentially distributed guide through holes 114, the guide through holes 114 are arranged in an inclined manner, and the inclination angle is the angle from the traction rope installation point 63 to the abutting through hole 112; thus, the guide through holes 114 can play a guiding role, the stability of the traction rope is ensured, and the interference caused by the winding of the traction rope is avoided, and the two ends of the guide through holes 114 are provided with arc chamfers.

[0063] The guide disc 113 and the abutting adjusting table 111 can be integrally arranged with the upper and lower covers of the handle or can be fixedly connected through glue.

[0064] In some embodiments, referring to Figures 2-4 The handle is internally provided with four traction ropes 8, the two ends of the traction ropes 8 are fixedly connected with the front end of the snake bone and the traction rope installation point 63, respectively, the four traction ropes 8 are provided with soft stainless steel sleeves 81 except the two end positions, the stainless steel sleeves 81 are provided with abutting bosses 82, and the abutting bosses 82 are arranged on the side of the abutting adjusting table 111 close to the insertion part 2.

[0065] The traction rope 8 is arranged in sequence through the abutting through hole 112, the guide through hole 114 and the traction rope installation point 63, and when the adjusting rocker 9 drives the adjusting disc 6 to rotate around the installation ball head 1151, the traction of the traction rope 8 is completed, because the diameter of the abutting boss 82 is greater than that of the abutting through hole 112, the traction rope 8 can move relative to the stainless steel sleeve 81, and thus the smoothness of the movement is ensured.

[0066] Referring to Figure 1 The handle is provided with a main machine connecting line 4, the main machine connecting line 4 is arranged on the proximal side surface of the handle, thus, the interference with the adjusting rocker is avoided, and the comfort of holding is ensured.

[0067] Referring to Figure 2, the stainless steel sleeve 81 is arranged outside the insertion part 2 and fixed and sealed by the heat-shrinkable sleeve 20; further, the insertion part 2 is provided with four traction rope mounting through holes 22 for mounting the stainless steel sleeve 81, and the stainless steel sleeve 81 is movably mounted in the traction rope mounting through hole 22, and the above two modes have advantages in cost, mounting mode and outer diameter size.

[0068] Referring to Figure 11 , in order to avoid the movement direction of the adjusting rocker 9 being inconsistent with the movement direction of the image acquisition part 3, and not conforming to the daily operation habit, the adjusting disc 6 and the adjusting rocker 9 are provided with a telescopic connecting rod 94.

[0069] The adjusting disc 6 is provided with a second ball-shaped mounting groove 65 at one end close to the adjusting rocker 9, the adjusting rocker 9 is provided with a telescopic rod mounting groove 93 at one end close to the adjusting disc 6, and the telescopic connecting rod 94 is movably mounted in the telescopic rod mounting groove 94; the telescopic connecting rod 94 and the bottom surface of the telescopic rod mounting groove 93 are provided with a contact spring 941, and the other end of the telescopic connecting rod 94 is provided with a connecting groove matched with the second ball-shaped mounting groove 65;

[0071] The third ball-shaped mounting groove 121 is arranged between the adjusting disc 6 and the adjusting disc 6, and one half of the mounting groove can be arranged on the handle upper cover 11 and the handle lower cover 12, and when they are combined, the installation of the rocker mounting spherical surface 93 is completed.

[0072] Through the above arrangement, when the adjusting rocker 9 is pushed to rotate in one direction during adjustment, the telescopic connecting rod 94 will rotate around the rocker mounting spherical surface 93, the telescopic connecting rod 94 drives the adjusting disc 6 to rotate in the opposite direction, the rotating direction of the adjusting disc 6 is opposite to that of the adjusting rocker 9, the tightening direction of the adjusting disc 6 is the same as that of the image acquisition part 3 when the adjusting disc 6 rotates, and the image acquisition part 3 rotates in the tightening direction, so that the pushing direction of the adjusting rocker 9 is consistent with that of the image acquisition part 3, and the operation habit and comfort are ensured.

[0073] The above is the preferred embodiment of the present application, and those skilled in the art can make various transformations or improvements on the basis of the above, and these transformations or improvements shall belong to the scope of protection of the present application without departing from the general concept of the present application.
