Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged in appropriate circumstances, so that the embodiments of the present application described here.

[0034] The present invention provides a laparoscope telescopic device, which can arbitrarily telescope the laparoscope body, thereby facilitating the detection and use of the laparoscope body, and can also adjust the laparoscope body to different positions to further expand the range of detection inside the patient's abdominal cavity.

[0035] like Figure 1 As shown, a telescopic device of a laparoscope includes a bottom plate 2, a rocker plate 3, a top plate 4 and a rotating ring 6, wherein the bottom plate 2 is arranged at the bottom of the laparoscope body 1, for example, the bottom plate 2 is circular, and the top plate 4 is arranged at the top of the laparoscope body 1, for example, the top plate 4 is circular, and a first through hole 401 is arranged in the middle of the top plate 4.

[0036] The bottom of the top plate 4 is fixedly connected to the top of the laparoscope body 1 through a fixing structure, for example, Figure 3 As shown, the fixing structure includes an outer screw barrel 402 and an inner screw barrel 5 which are arranged in the middle position of the bottom of the top plate 4. The top of the laparoscope body 1 is inserted into the inside of the outer screw barrel 402. The inner thread of the inner screw barrel 5 is threadedly connected with the outer thread of the outer screw barrel 402 to fix the top of the laparoscope body 1 to the top plate 4.

[0037] like Figure 3 As shown, both sides of the top plate 4 are provided with rotating rods 403. Figure 1 As shown, each rotating rod 403 is sleeved with a rotating ring 6, and the rotating ring 6 is rotatably connected to the rotating rod 403, as shown in FIG. Figure 4 As shown, moving rings 601 are provided on both sides of each rotating ring 6 .

[0038] For example, each movable ring 601 is fixedly connected to the rotating ring 6 through a connecting rod 602. For example, the axial center line of the rotating ring 6 is perpendicular to the axial center line of the movable ring 601. For example, the connecting rod 602 is arc-shaped, so that the circle formed by the centers of the four movable rings 601 is concentric with the circular top plate 4.

[0039] For example, grooves 405 are symmetrically arranged on both sides of the top plate 4 along the center line, and one end of each rotating rod 403 is fixedly connected to a groove 405, for example, by welding, and the other end of each rotating rod 403 is rotatably connected to a rotating ring 6.

[0040] The rocking plate 3 is movably arranged on the top of the bottom plate 2. For example, the rocking plate 3 is circular, and the outer diameter of the rocking plate 3 is smaller than the outer diameter of the bottom plate 2. Figure 5 As shown, a rocker 301 is fixed on the top of the rocker ring plate 3 , and a second through hole 306 is provided on the rocker ring plate 3 , and the laparoscope body 1 slides in the second through hole 306 .

[0041] like Figure 2 As shown, a touch panel 201 is also provided at the bottom of the base plate 2. For example, the touch panel 201 is circular, and the outer diameter of the touch panel 201 is equal to the outer diameter of the base plate 2. A third through hole 202 is provided in the middle of the base plate 2 and the touch panel 201, and the bottom of the laparoscope body 1 passes through the interior of the third through hole 202.

[0042] like Figure 2 As shown, a limiting rod 203 is provided at the top of the bottom plate 2 on the outside of the rocking ring plate 3 in the vertical direction, a limiting rod 203 is provided corresponding to each moving ring 601, each moving ring 601 is slidably connected with a limiting rod 203, a limiting plate 205 is provided at the top of each limiting rod 203, the outer diameter of the limiting plate 205 is larger than the inner diameter of the rotating ring 6, and a spring 204 is sleeved on each limiting rod 203, the bottom of the spring 204 is in contact with the bottom plate 2, and the top of the spring 204 is in contact with the moving ring 601.

[0043] When the top plate 4 moves up and down, the rotating ring 6 will drive the moving ring 601 to slide on the limiting rod 203, so that the rotating ring 6 can only slide up and down, thereby ensuring the stability of the movement of the laparoscope body 1. At the same time, the limiting plate 205 blocks and limits the moving ring 601, so that after the top plate 4 is released, the spring 204 on the limiting rod 203 will push the top plate 4. At this time, the limiting plate 205 can prevent the moving ring 601 from being pushed out on the surface side of the limiting rod 203.

[0044] When the telescopic device of the present invention is in use, the top of the laparoscope body 1 is fixedly connected to the top plate 4 through the cooperation of the inner screw barrel 5 and the outer screw barrel 402. At this time, the up and down movement of the top plate 4 can directly drive the up and down movement of the laparoscope body 1, thereby allowing the laparoscope body 1 to arbitrarily adjust the insertion length of the laparoscope body 1 when it is working. At the same time, when the top plate 4 is loosened, the spring 204 will directly push the top plate 4 to move upward and retract the laparoscope body 1, thereby realizing the telescopic processing of the laparoscope body 1.

[0045] For example, the rocker plate 3 is provided with a screw hole 304 in a direction perpendicular to the center line of the second through hole 306, the screw hole 304 is communicated with the second through hole 306, and a screw rod 302 is threadedly connected inside the screw hole 304. When the laparoscope body 1 is moving, the screw rod 302 is turned out inside the screw hole 304, so that when the laparoscope body 1 is moving, the screw rod 302 does not contact the laparoscope body 1, and when positioning the laparoscope body 1, the rotating screw rod 302 is turned inside the screw hole 304, so that the screw rod 302 abuts against the laparoscope body 1 in the second through hole 306, thereby clamping the laparoscope body 1.

[0046] For example, a first ball hole 206 is provided on the top of the base plate 2, a second ball hole 305 is provided on the bottom of the rocking ring plate 3 at a position corresponding to the first ball hole 206, a double ball rod 303 is provided between the rocking ring plate 3 and the base plate 2, and two ends of the double ball rod 303 are rotatably connected to the first ball hole 206 and the second ball hole 305 respectively. When the rocking ring plate 3 moves, the rocking ring plate 3 will rotate inside the first ball hole 206 and the second ball hole 305 through the two ends of the double ball rod 303, so that the rocking ring plate 3 can be shaken around and the rocking ring plate 3 can be assembled with the base plate 2.

[0047] For example, the outer barrel 402 is made of plastic, the inner barrel 5 is conical, and the minimum inner diameter of the conical inner barrel 5 is equal to the inner diameter of the outer barrel 402, so that the inner barrel 5 can be squeezed and deformed against the outer barrel 402, thereby assembling and connecting the laparoscope body 1 and the top plate 4.

[0048] For example, the aperture of the first through hole 401 is smaller than the aperture of the outer screw barrel 402. The outer screw barrel 402 is provided with a plurality of strip openings 404 along the circumferential direction. The strip openings 404 extend through the bottom of the outer screw barrel 402. The conical inner screw barrel 5 rotates on the outer screw barrel 402, and squeezes the surface side wall of the outer screw barrel 402 at the position of the strip openings 404, so that the outer screw barrel 402 can squeeze the laparoscope body 1 and fix the laparoscope body 1.

[0049] The cable at the upper end of the laparoscope body 1 passes through the first through hole 401. When the rocker plate 3 pushes the movement of the laparoscope body 1, the top of the laparoscope body 1 will also shake. At this time, the laparoscope body 1 will drive the top plate 4 to shake its position through the outer screw 402, and then the top plate 4 will cause the rotating rod 403 to rotate inside the rotating ring 6. At the same time, the rotating rod 403 is in the internal position of the rotating ring 6, so that the top plate 4 can be supported.

[0050] The working principle of the telescopic device of the laparoscope of the present invention is as follows: by inserting the top of the laparoscope body 1 into the interior of the outer screw barrel 402, the cable end of the laparoscope body 1 can pass through the first through hole 401, and the cable of the laparoscope body 1 can be plugged into the external device, and then by rotating the inner screw barrel 5, the inner screw barrel 5 can be squeezed against the outer screw barrel 402, and the laparoscope body 1 is fixedly connected to the top plate 4. Therefore, when the laparoscope body 1 needs to be telescoped, the top plate 4 can be moved downward, and the top plate 4 can drive the rotating ring 6 and the moving ring 601 to slide downward through the rotating rod 403, and compress the spring 204, and the sliding of the top plate 4 will drive the movement of the laparoscope body 1, so as to adjust the length of the laparoscope body 1 inside the abdominal cavity, and at the same time, when the top plate 4 is loosened, the spring 204 directly pushes the top plate 4 upward, so that the laparoscope body 1 can be moved out of the abdominal cavity, thereby realizing the telescopic of the laparoscope body 1.

[0051] When the angle of the laparoscope body 1 needs to be adjusted, the rocker plate 3 is pushed by the rocker arm 301, so that the rocker plate 3 will push the laparoscope body 1 to shake inside the third through hole 202. At this time, the rotating rod 403 on the top plate 4 rotates in the rotating ring 6, and the top plate 4 moves with the laparoscope body 1, so that the lens at the lower end of the laparoscope body 1 can observe different positions in the abdominal cavity.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
