DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0030] Embodiment 1

[0031] Reference Figs. 1-4 The embodiments of the present application provide a laparoscopic suturing device capable of quickly replacing multi-needle type suturing, which comprises a three-jaw module 1 and a control main body 2.

[0032] The three-jaw module 1 comprises a main body bottom support chuck 100, a vertical chuck 101, and a horizontal chuck 102. The vertical chuck 101 is provided with a first hinged shaft on the side facing the horizontal chuck 102, and the horizontal chuck 102 is provided with a through hole matched with the first hinged shaft, and the horizontal chuck 102 is rotationally connected with the vertical chuck 101 through the first hinged shaft.

[0033] The main body bottom support chuck 100 is provided in two groups, and the two groups of main body bottom support chucks 100 are parallel to each other, and the vertical chucks 101 are distributed between the two groups of main body bottom support chucks 100. The two groups of main body bottom support chucks 100 are respectively provided with through holes, and the vertical chucks 101 are respectively provided with second hinged shafts on the two sides, and the vertical chucks 101 are rotationally connected with the main body bottom support chucks 100 through the two groups of second hinged shafts.

[0034] The horizontal chuck 102 is distributed on one side of the vertical chuck 101, and the horizontal chuck 102 and the vertical chuck 101 are distributed above the main body bottom support chuck 100.

[0035] The control body 2 can control the lateral clamp 102 to rotate laterally around the first hinge axis towards or away from the vertical clamp 101, and when the lateral clamp 102 is flipped laterally towards the vertical clamp 101 until closed, the suture needle can be stably held between the vertical clamp 101 and the lateral clamp 102, and when the lateral clamp 102 is flipped laterally away from the vertical clamp 101, the vertical clamp 101 and the lateral clamp 102 are separated, and the suture needle can be taken out. The control body 2 can control the vertical clamp 101 to rotate longitudinally around the second hinge axis towards or away from the body bottom support clamp 100.

[0036] The contact surface of the lateral clamp 102 and the vertical clamp 101 can be flat, circular, or irregular curved, and the material can be metal, plastic, or ceramic.

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

[0051] Embodiment 4

[0052] The main body structure of the present embodiment is the same as that of Embodiment 3, except that the structure of the first compression mechanism 204 and the second compression mechanism 208 is limited in the present embodiment.

[0053] Specifically, referring to Fig. 5 In the present embodiment, the first compression mechanism 204 includes a first horizontal mounting slot, a first spring, and a first pressing plate.

The second pressing plate is in sliding connection with the second horizontal mounting slot.

[0055] Embodiment 4

[0056] The main body structure of the present embodiment is the same as that of Embodiment 3, except that the structure of the first compression mechanism 204 and the second compression mechanism 208 is limited in the present embodiment.

[0057] Specifically, referring to Fig. 5 In the present embodiment, the rotating head 209 is rotatably connected with the main body shell 200 through a bearing piece. The main body bottom support clamp 100, the first horizontal control guide rod 105, and the first vertical control guide rod 106 are all fixedly connected with the rotating head 209.

[0058] Two horizontal through holes are formed in the rotating head 209, and the first horizontal control guide rod 105 and the first vertical control guide rod 106 respectively pass through the two horizontal through holes and extend to the inside of the main body shell 200, and are rotatably connected with the horizontal control linkage assembly and the vertical control linkage assembly.

[0059] When the three-jaw module 1 needs to be rotated, the rotating head 209 is screwed, and the first transverse control guide rod 105, the first longitudinal control guide rod 106 and the body bottom support jaw 100 are also rotated, facilitating the adjustment of the angle of the three-jaw module 1.

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

[0061] In application, the doctor only needs to control the opening and closing of the transverse jaw 102 and the vertical jaw 101 through the first power output trigger 203 and the second power output trigger 207, and can perform 360-degree free rotation of the three-jaw module through the rotating head 209, realizing the operation of suturing the human tissue in different environments.

[0062] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and refinements without departing from the principle of the present application shall be considered as the protection scope of the present application.
