Laparoscopic surgery minimally invasive suturing device

Abstract

A minimally invasive suturing device for laparoscopic surgery, belonging to the field of medical technology, includes a suturing component and a second limit block, the suturing component includes a suture block, the second limit block is provided with a first chute, the A slider is slidably connected in the first chute, a clamping block is fixedly connected to the side of the stitching block close to the first chute, a clamping groove is opened inside the slider, and the clamping block is clamped The groove is clamped with the slider, and a bushing is nested inside the clamping groove. The material of the bushing is a rubber composite material. The setting of the clamping groove and the clamping block can further improve the suture assembly and the suture device. The stability between the suture blocks solves the disadvantage that the suture block is easily shaken after installation due to the plugging method used in the traditional suture device to replace the suture block. At the same time, the first limit block and the second limit block are connected by rotation. , which can effectively solve the problem of friction between the first limit block and the second limit block caused by the installation of the suture block.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a minimally invasive suturing device for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a type of minimally invasive surgery. Laparoscopic surgery is a medical device with a miniature camera. Laparoscopic surgery is an operation performed using laparoscopy and related instruments. The internal observation is performed to complete the operation of the relevant medical operation. The tiny trauma caused by the laparoscopic operation often needs to be sutured with a minimally invasive suturing device, and then the whole process of the laparoscopic operation is completed. [0003] In the prior art, the patent whose publication number is CN208958200U discloses a minimally invasive suturing device, which includes a brake, an elongated shaft, a ball joint and a suture head connected in sequence, and the ball joint includes a bending hemisphere and a rotating...

Problems solved by technology

[0003] In the prior art, the patent whose publication number is CN208958200U discloses a minimally invasive suture device, which includes sequentially connected brakes, elongated shafts, ball joints and suturing heads. The ball joints include adjustable bending hemispheres and rotating hemispheres. The proximal surface of the hemisphere and the distal surface of the bending hemisphere fit each other, and the distal end of the rotating hemisphere is connected with the proximal end of the suture head. Connected with the brake, there is a passage for the rotating part to pass through in the ball joint, the rotating part extends along the central axis of the ball joint and the distal end is connected to the suturing head, and the rotating part is controlled by the brake so that the sewing head and the rotating hemisphere are along the central axis The direction is rotated synchronously, the proximal end of the bending part is connected with the brake, and the far end of the bending part is connected with the bending hemisphere, and the bending part is controlled by the brake to make the bending hemisphere drive the rotating hemisphere to realize the center of the suture head relative to the ball joint The axis swings; the suture head can be flexibly adjusted and rotated, and the precise positioning of the suture head can be realized. However, when the stapler replaces the suture head, the plug-in method is used, which may easily cause friction between the stapler and the suture head. After replacing the suturing head many times, there is a certain gap between the suturing device and the insertion and extraction of the suturing head, which causes the installed suturing head to shake inside the suturing device. Cause suture accidents in the suture process, which is not conducive to the development of medical devices, for this reason, a minimally invasive suture device for laparoscopic surgery is proposed
