Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an intracavity purse-string forceps for laparoscopic surgery according to an embodiment of the present invention. It can be seen that the intracavity purse-string forceps for laparoscopic surgery includes: the handle, connecting rod 20, clamping part and drive mechanism, drive mechanism sets up in the connecting rod, drive mechanism connects the handle with the clamping part.
Specifically, referring to fig. 1 and 2, the clamping portion includes a first transition portion 41 and a second transition portion 42, and the first transition portion 41 and the second transition portion 42 are bent away from each other to form a gap.
By providing the first transition portion 41 and the second transition portion 42 in this way, the effect of the first transition portion 41 and the second transition portion 42 on the operation during suturing can be avoided.
With reference to fig. 2, the first transition portion extends out of the first sewing portion 411, the second transition portion extends out of the second sewing portion 421, and the first sewing portion 411 and the second sewing portion 421 are provided with sewing holes 430 at their abutting sides.
In a preferred embodiment, the first stitching 411 is perpendicular to the first transition portion 41, and the second stitching 421 is perpendicular to the second transition portion 42.
In addition, the stitching portions 411 and 421 and the transition portions 41 and 42 may have other included angles, and the comparison of the present invention is not particularly limited.
Further, referring to fig. 3, a guide disc 440 is disposed at one end of the first stitching portion 411 and the second stitching portion 421 near the first transition portion and the second transition portion. Suture holes 430 are provided in the guide disk 440.
Through the arrangement of the guide disc, the guide function during sewing can be realized, and the double straight needles on the purse-string thread can be conveniently placed.
Further, a rotating member 30 is disposed at an end of the connecting rod 20 facing the clamping portion to rotate the clamping portion.
In one embodiment, the length of the intracavity purse-string forceps for laparoscopic surgery is 40 cm-50 cm. Specifically, this length may be the dimension along the length of the connecting rod 20 from the distal end of the handle to the front end of the grip.
In the present embodiment, the handle includes a first handle 11 and a second handle 12, at least the second handle 12 is movable, and the second handle 12 is connected with the second transition portion 42 through a transmission rod. Fig. 4 shows the state when the clamping portion is opened.
Referring to fig. 5 and 6, a possible transmission mechanism is illustrated in an embodiment of the present invention. If the second handle 12 is coupled to the main lever 32 through the first transmission lever 122, the main lever 32 is disposed in the coupling rod 20, and one end of the second handle 12 is disposed inside the upper end of the first handle 11 through the fixing shaft 121 so as to be rotated, the first transmission lever 122 is coupled to the main lever 32 near the fixing shaft 121 and toward a direction away from the clamping portion. Thus, when the second handle 12 is gripped and moved toward the first handle 11, the main lever 32 is moved in the handle direction.
The other end of the main rod 32 is connected with a second transmission rod, the second transmission rod is connected with the second transition part 42, and a movable pin 33 is arranged at the joint of the second transmission rod and the second transition part. Further, the movable pin 33 can slide along the slide rail 31. Thus, when the main rod 32 moves towards the handle, the second transmission rod is pulled, so that the second transition portion 42 moves from the inclined direction to the direction parallel to the axial direction of the connection rod 20, and the second stitching portion 421 abuts against the first stitching portion 411.
In one embodiment, for configurations having a rotating member 30, the primary shaft 32 may be a rotatable configuration, such as a multi-part nested rotary configuration.
The intracavity purse-string forceps for laparoscopic surgery provided by the utility model can be used for clamping a part to be sutured by utilizing the transverse first suturing part 411 and the transverse second suturing part 421 during surgery, and placing double straight purse-string needles into the suturing holes 430 to complete purse-string suturing, so that the surgery difficulty is greatly reduced, and particularly, the intracavity purse-string forceps for laparoscopic surgery are more intuitive in operation when placing esophageal purse-string suturing, and further can effectively shorten the surgery time.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
