Description
Technical Field
The invention relates to a medical appliance, in particular to a suture device for a hernia sac with a lineal hernia.
Background
A white line hernia is an extraabdominal hernia occurring in the midline of the abdominal wall (i.e., the white line), mostly occurring between the umbilicus and the xiphoid process (more at the midpoint of the two), and is also referred to as an epigastric hernia. The white line hernia usually has no significant symptoms except for the tumor mass, and sometimes can be misdiagnosed as abdominal wall lipoma. Surgery is the only effective method for curing white line hernia. After the occurrence of the white line hernia, the repair is usually performed by adopting a common surgical operation, and the traditional operation mode adopts an open method repair operation: (1) making a longer vertical incision or transverse incision at the hernia site; cutting skin and subcutaneous tissue, separating to deep until hernia or its rupture is identified, and determining whether there is hernia sac; (2) if it is determined to be a hernia, the hernia sac is incised and its contents are received. Then separating the hernia sac, ligating at the high position of the peritoneal plane, cutting off the redundant hernia sac, and pushing the stump of the hernia sac and the like into the lower part of the cleft of the fascia of the linea alba; the fascia of the white thread is drawn together and sutured or folded and sutured by nylon thread. (3) The subcutaneous tissue and the skin were sutured layer by layer. In view of the trauma to the patient and the complications after the operation, the traditional operation mode is not popular. At present, the white thread hernia repair under a laparoscope is an increasingly clinically applied surgical mode. The specific operation steps are as follows: firstly), 3-4 puncture holes are formed in the abdominal wall on one side of a patient, and an instrument is inserted into the abdominal cavity under the direct view of a monitor; and secondly) sewing the top end and the two side walls of the hernia sac with the white thread by using a sewing needle and a sewing thread, thereby closing the space formed by the hernia sac. Thirdly), an anti-adhesion patch is placed on the inner side of the abdominal wall with the hernial sac closed and is fixed properly. The laparoscopic method for repairing the white line hernia has the obvious advantages of small wound, quick recovery, few near and long term complications, definite repairing effect, small recurrence rate and the like. Because the hernia sac is positioned on the anterior abdominal wall and protrudes out of the body surface, the laparoscopic surgery mode needs to suture and close the hernia sac in a narrow space of the abdominal cavity, which is the most difficult point of the laparoscopic surgery mode for repairing the abdominal albugineal hernia. The operation difficulty of closing the hernial sac by suturing is high, the operation technology is not easy to master, and the popularization and the application of the white line hernial repair by a laparoscope mode are greatly limited.

As shown in fig. 10, the fixing tube 4 is driven to rotate towards the right side of the hernia sac 7, so that the forceps head assembly of the fixing forceps 2 on the right side of the fixing plate 5 is aligned with the right side of the hernia sac 7, and the rotation angle can be judged through the camera; after the binding clip subassembly of the fixed pincers 2 on right side aims at the hernia bag 7 right side, the operating handle of the fixed pincers 2 on right side is handed and slowly impel the driving wire in the fixed pipe 4, until the binding clip subassembly reaches the right side of hernia bag 7, utilize thumb and forefinger to rotate the nut, the rotation of nut can be changed into the rectilinear motion of screw rod, the rectilinear motion of screw rod can drive driving wire push-and-pull binding clip subassembly, the link mechanism through the binding clip subassembly drives left and right binding clip open and shut, after left and right binding clip's opening alignment position, the contra-rotation nut drives left and right binding clip tightly the right side tissue of hernia bag 7, under the condition of not rotating the nut, the binding clip subassembly can continuously exert the clamping-force to the tissue. Finally, as shown in figures 11 and 12, the fixing tube 4 is rotated to the intermediate position, and then the driving wires of the three fixing jaws 2 are pulled simultaneously to pull back the left, top and right sides of the clamped hernia sac 7 onto the fixing plate 5, at which time the tissues of the three points of force of the hernia sac 7 are close together.
A sewing step: as shown in fig. 13, the rear end of the titanium spring 8 is inserted into the abutting sleeve 94 of the transmission rod 93, the titanium spring 8 extends into the cavity from the rear end orifice of the fixed tube, the transmission rod 93 is used for pushing the titanium spring 8 forward, and the titanium spring 8 stops when the front end needle of the titanium spring 8 abuts against the hernial sac tissue; then, the motor 91 is started, the motor 91 drives the titanium spring 8 to rotate through the transmission rod 93, thrust is applied to the titanium spring 8 through the transmission rod 93 in the rotating process, the titanium spring 8 has a forward trend, and a needle head at the front end of the titanium spring 8 can penetrate into the hernia sac; the titanium spring 8 is continuously pushed forward by slowly pushing the transmission rod 93, and finally the titanium spring 8 can stitch the left side, the top and the right side of the hernia sac together. Taking out the transmission rod 93 and separating the rear end of the titanium spring 8 from the butting sleeve 94; to prevent the titanium spring 8 from loosening, the front and rear ends of the titanium spring 8 may be hooked after sewing.
In addition, in the above-mentioned suture step, after the front end needle of the titanium spring 8 abuts against the hernial sac tissue, the pushing force can be continuously applied to the titanium spring 8 to compress the titanium spring, and then the position of the motor 91 is fixed by the guide sleeve 92; then starting the motor 91, driving the titanium spring 8 to rotate by the motor 91 through the transmission rod 93, pressing the titanium spring 8 to one side of the hernia sac tissue in the rotating process, and finally enabling the needle head of the titanium spring 8 to penetrate into the hernia sac tissue; during the continuous rotation of the titanium spring 8, the titanium spring 8 is slowly stretched under the action of the elastic force and passes through the tissues of the hernia sac pulled back by the fixing forceps, and finally the titanium spring 8 can stitch the left side, the top and the right side of the hernia sac together.
