After an operation, anastomotic stoma and upper and lower tissue damage caused by various reasons lead to poor healing or closure of the anastomotic stoma, resulting in anastomotic stoma air leakage, anastomotic stoma exudation, anastomotic stoma bleeding, anastomotic stoma fistula and the like. The incidence of a neck anastomotic stoma fistula is about 10%, the incidence of a chest anastomotic stoma is about 5%, and the incidence of an abdominal cavity anastomotic stoma is about 1%.

[0026] The backing feeding and reinforcing patch feeding device of the reinforcement and repair assembly stitching machine is used in conjunction with the automatic stitching machine for anastomotic reinforcement and repair assemblies. The working principle of the automatic stitching machine for anastomotic reinforcement and repair assemblies is as follows:

[0027] When the automatic stitching machine for anastomotic reinforcement and repair assembly is in operation, the backing feeding device is started by touching the operation display screen, power switch, and control switch. Under the control of the PLC programmable controller, the backing is fed by the feeding roller drive motor, which drives the feeding active roller. After reaching a certain length, the backing cutting cylinder drives the backing cutting blade to cut it. Then, the synchronous belt drive motor drives the synchronous belt, which drives the pressing cylinder mounting plate. The pressing cylinder drives the pressing plate to press the cut backing and slide it along the worktable to the worktable folding station. The reinforcement and repair piece is placed on the backing and folded.

[0028] When the reinforcing patch is placed on the upper part of the backing, the backing edge device works under the control of the PLC programmable controller. The front and back correction cylinders and the correction plate correct the front and back positions. The up and down pressure cylinder and the pressure plate press the reinforcing patch tightly on the upper part of the backing. The front and back moving cylinder of the backing edge is started. The front and back displacement of the backing edge is adjusted. The up and down cylinder of the backing edge presses the backing tightly. The flanging plate set on the left and right moving cylinder of the backing edge pushes the front end of the backing backward to perform flanging. The flanging plate is folded into the required length. After the flanging is completed, the front and back moving cylinder of the backing edge is withdrawn.

[0029] After the backing edge is completed, the reinforcing patch assembly conveying device is controlled by the PLC programmable controller. The X and Y direction linear motor module drives the reinforcing patch assembly pressure plate to press the reinforcing patch assembly after the flanging is completed. The reinforcing patch assembly is conveyed to the lower part of the corner cutting mechanism along the workbench. The moving cutter one of the corner cutting mechanism cuts off one side corner first. Then the moving cutter two cuts off the other side corner. After the corner cutting is completed, the reinforcing patch assembly conveying device conveys the corner-cutting reinforcing patch assembly to the industrial sewing machine of the reinforcing patch sewing device one to perform one side sewing. After the one side sewing of the reinforcing patch assembly, the reinforcing patch assembly conveying device is conveyed forward to exit the needle point position. The front and back telescopic cylinder of the sewing line is extended. The pressure cylinder one is started. The pressure plate presses the last coil after the sewing. The thread pulling cylinder of the reinforcing patch sewing device one works. The reciprocating motion pulls the thread a distance to leave the thread end one. The industrial sewing machine is reversed to make the sewing machine curved needle thread breaking. The X and Y linear transmission module of the reinforcing patch assembly conveying device is controlled by the PLC. After the reinforcing patch assembly is pressed tightly, it is conveyed to the transfer position of the vacuum suction plate two. The rear end thread pulling cylinder is extended again. The rear end thread pulling lifting cylinder is pressed down. The thread is hooked by the hooking plate. The rear end thread pulling cylinder is retracted to reserve a required length of the rear end thread. The thread pulling cylinder is pulled again. The front end thread pulling cylinder is extended. The thread is hooked and retracted. The pneumatic finger clamps the thread when it is retracted. The pneumatic scissors lifting cylinder is down to cut the thread end by the pneumatic scissors. The reinforcing patch assembly conveying device returns to the original position to perform the next cycle.

[0030] The reinforced patch assembly discharging device is started, the pressing plate moves to the second transfer position of the vacuum suction plate of the workbench, the up-and-down pressing cylinder of the reinforced patch presses the assembled reinforced patch with one side sewn to be transferred to the lower part of the sewing needle of the industrial sewing machine of the second reinforced patch sewing device, the other side of the reinforced patch assembly is sewn, after the other side of the reinforced patch assembly is sewn, the reinforced patch discharging device is transferred forward to exit the needle tip position, the front and rear retractable cylinder of the sewing thread is extended, the second pressing cylinder is started, the pressing plate one presses the last loop after sewing, the thread pulling cylinder of the second reinforced patch sewing device works, reciprocatingly moves to pull out a distance of the thread to leave the second thread end, the industrial sewing machine is reversed to make the sewing machine bend needle thread, under the control of the PLC, the rear end of the thread pulling cylinder is extended again after the thread pulling cylinder reciprocates again, the rear end of the thread pulling lifting cylinder is pressed down, the thread is hooked through the hooking plate, the rear end of the thread is reserved to the required length, the thread is pulled again, the front end of the thread pulling cylinder is extended, the thread is hooked and retracted, the pneumatic finger clamps the thread when retracted, the pneumatic scissors lifting cylinder is down to cut the thread end through the pneumatic scissors, the reinforced patch assembly is made after the thread is cut by the pneumatic scissors, the reinforced patch assembly is formed by sewing the reinforced patch and the backing, the reinforced patch assembly discharging device of the reinforced patch assembly discharging device is driven by the linear motor module to discharge the reinforced patch assembly, and the reinforced patch assembly product is discharged.
