Specific implementation method:

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] Reference Figures 1 to 4 An embodiment of the present invention provides a laparoscopic suturing device capable of realizing quick replacement of multi-needle suturing, comprising a three-chuck module 1 and a control body 2.

[0032] The three-clamp module 1 includes a main body bottom support clamp 100, a vertical clamp 101 and a horizontal clamp 102. A first hinge axis is arranged on the side of the vertical clamp 101 facing the horizontal clamp 102, and a through hole adapted to the first hinge axis is arranged on the horizontal clamp 102. The horizontal clamp 102 is rotatably connected to the vertical clamp 101 through the first hinge axis.

[0033] Two groups of main body bottom support chucks 100 are arranged, and the two groups of main body bottom support chucks 100 are parallel to each other, and the vertical chuck 101 is distributed between the two groups of main body bottom support chucks 100, and through holes are arranged on the two groups of main body bottom support chucks 100 respectively, and second hinge shafts are arranged on both sides of the vertical chuck 101 respectively, and the vertical chuck 101 is rotatably connected with the main body bottom support chuck 100 through the two groups of second hinge shafts.

[0034] The transverse clamp 102 is distributed on one side of the vertical clamp 101 , and the transverse clamp 102 and the vertical clamp 101 are distributed above the main body bottom supporting clamp 100 .

[0035] The control body 2 can control the transverse clamp 102 to rotate horizontally with the first hinge axis as the axial direction in the direction close to or away from the vertical clamp 101. When the transverse clamp 102 is turned horizontally toward the vertical clamp 101 until it is closed, the suture needle can be stably held between the vertical clamp 101 and the transverse clamp 102. When the transverse clamp 102 is turned horizontally away from the vertical clamp 101, the vertical clamp 101 is separated from the transverse clamp 102, and the suture needle can be taken out. The control body 2 can control the vertical clamp 101 to rotate longitudinally with the second hinge axis as the axial direction in the direction close to or away from the main body bottom support clamp 100.

[0036] The contact surfaces of the transverse clamp 102 and the vertical clamp 101 can be flat, circular or irregularly curved, and can be made of metal, plastic or ceramic.

[0037] In the present device, the transverse chuck 102 and the vertical chuck 101 are similar to the left and right chucks of the suture needle clamp, but the transverse flipping of the transverse chuck 102 and the longitudinal flipping of the vertical chuck 101 do not affect each other and can be performed simultaneously. When the vertical chuck 101 flips longitudinally, the transverse chuck 102 also flips longitudinally. When the vertical chuck 101 flips longitudinally, closes or opens, the transverse chuck 102 can open or close freely. In this way, when the transverse chuck 102 and the vertical chuck 101 clamp the suture needle, they can form another set of clamps with the main body bottom supporting chuck 100. The main body bottom supporting chuck 100 is similar to a bottom support plate. The transverse chuck 102 can clamp suture needles of different needle diameters. When the transverse chuck 102 and the vertical chuck 101 clamp the suture needle and rotate and close with the main body bottom supporting chuck 100, the clamped suture needle can penetrate human tissue, thereby realizing the function of suturing human tissue with the suture thread with the suture needle. Since the transverse clamp 102 can independently rotate transversely at any time when the vertical clamp 101 rotates vertically and closes, when the transverse clamp 102 is opened, the suture needle clamped by the transverse clamp 102 and the vertical clamp 101 is no longer clamped. At this time, suture needles of different needle types can be quickly replaced. This design can adapt to suture needles of multiple specifications and has a wide range of applications.

The transverse control linkage assembly can control the reciprocating motion of the first transverse control rod 105, and the first transverse control rod 105 drives the transverse clamp 102 to rotate horizontally through the second transverse control rod 104, thereby realizing the opening or closing of the transverse clamp 102.

[0042] The second control mechanism includes a first longitudinal control guide rod 106, a second longitudinal control guide rod 103 and a longitudinal control linkage assembly, wherein the longitudinal control linkage assembly is connected to the first longitudinal control guide rod 106, a connecting piece is hinged at the end of the first longitudinal control guide rod 106, the connecting piece is hinged to one end of the second longitudinal control guide rod 103, and the other end of the second longitudinal control guide rod 103 is hinged to the bottom of the vertical clamp 101. The longitudinal control linkage assembly can control the reciprocating motion of the first longitudinal control guide rod 106, and the first longitudinal control guide rod 106 drives the vertical clamp 101 to rotate longitudinally through the second longitudinal control guide rod 103, thereby realizing the opening or closing of the vertical clamp 101.

One end of the first linkage guide rod 201 is fixedly connected to the fourth linkage guide rod 211, and the other end is connected to the first lateral control guide rod 105 (rotatably connected). The fourth linkage guide rod 211 moves in the same direction as the first linkage guide rod 201 and the first transverse control guide rod 105. The first compression mechanism 204 is a structure that can be deformed and has elastic potential energy, and can perform telescopic movement under stress.

After loosening the first power output trigger 203, the first compression mechanism 204 generates a force on the fourth linkage guide rod 211, and the fourth linkage guide rod 211 drives the first linkage guide rod 201 and the first transverse control guide rod 105 to move toward the three-clamp module 1. The first transverse control guide rod 105 drives the transverse clamp 102 to rotate laterally away from the vertical clamp 101 through the second transverse control guide rod 104, and the transverse clamp 102 is separated from the vertical clamp 101.

[0047] Reference Figure 5, the longitudinal control linkage assembly includes a second power output trigger 207 and a fifth linkage guide rod 205, a sixth linkage guide rod 206, a seventh linkage guide rod 213 and a second compression mechanism 208 arranged inside the main housing 200.

When the vertical clamp is closed or opened in the vertical rotation, the horizontal clamp can be opened or closed freely.

[0051] Example 4

[0052] The main structure of this embodiment is the same as that of Embodiment 3, except that this embodiment limits the structures of the first compression mechanism 204 and the second compression mechanism 208 .

[0053] Specifically, refer to Figure 5 In this embodiment, the first compression mechanism 204 includes a first horizontal mounting groove, a first spring and a first pressing plate. The first horizontal mounting groove is fixedly arranged in the main housing 200. The first spring is arranged inside the first horizontal mounting groove.

The second pressing plate is slidably connected to the second horizontal mounting groove.

[0055] Example 4

[0056] The main structure of this embodiment is the same as that of Embodiment 3, except that: in this embodiment, a rotating head 209 is installed outside the main housing 200 .

[0057] Specifically, refer to Figure 5 In this embodiment, the rotating head 209 is rotatably connected to the main body housing 200 via a bearing. The main body bottom support clamp 100, the first transverse control guide rod 105 and the first longitudinal control guide rod 106 are all fixedly connected to the rotating head 209.

[0058] Two horizontal through holes are provided on the rotating head 209 , and the first transverse control guide rod 105 and the first longitudinal control guide rod 106 respectively pass through the two horizontal through holes and extend to the inside of the main shell 200 , and are rotationally connected with the transverse control linkage assembly and the longitudinal control linkage assembly.

[0059] When the three-clamp module 1 needs to rotate, the rotating head 209 is screwed, and the first transverse control guide rod 105 , the first longitudinal control guide rod 106 and the main body bottom support clamp 100 also rotate accordingly, so as to adjust the angle of the three-clamp module 1 .

[0060] In the present device, the transverse chuck 102 and the vertical chuck 101 are similar to the left and right chucks of the suture needle clamp, but the transverse flipping of the transverse chuck 102 and the longitudinal flipping of the vertical chuck 101 do not affect each other and can be performed simultaneously. When the vertical chuck 101 flips longitudinally, the transverse chuck 102 also flips longitudinally, and when the vertical chuck 101 flips longitudinally, closes or opens, the transverse chuck 102 can open or close freely. In this way, when the transverse chuck 102 and the vertical chuck 101 clamp the suture needle, they can form another set of clamps with the main body bottom supporting chuck 100. The main body bottom supporting chuck 100 is similar to a bottom support plate. When the transverse chuck 102 and the vertical chuck 101 clamp the suture needle and rotate and close the main body bottom supporting chuck 100, the clamped suture needle can penetrate human tissue, which is similar to a suture needle clamp (in surgical operations, doctors usually use suture needle clamps to hold suture needles to suture human tissue), thereby realizing the function of suturing human tissue with suture threads with suture needles. Since the transverse clamp 102 can independently rotate horizontally at any time when the vertical clamp 101 rotates vertically and closes, when the transverse clamp 102 is opened, the suture needle clamped by the transverse clamp 102 and the vertical clamp 101 is no longer clamped, and suture needles of different needle types can be quickly replaced.

[0061] When in use, the doctor only needs to control the opening and closing of the horizontal clamp 102 and the vertical clamp 101 through the first power output trigger 203 and the second power output trigger 207, and can freely rotate the three-clamp module 360 ​​degrees through the rotating head 209 to realize the operation of suturing human tissue in different environments.

[0062] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
