3 results about "Purse string suture" patented technology

A surgical stapler for applying a suture to tissue includes a first jaw and a second jaw configured to receive a cartridge. An actuation mechanism translates a drive member distally through the first and second jaws to apply staples to tissue such that a suture, in combination with the staples, forms a purse string when the stapler activated. The cartridge includes a first upper portion and a second lower portion.

The application discloses a cavity purse string suture device, which comprises a sleeve part, a lower clamp part fixed at the distal end of the sleeve part, an upper clamp part hinged to the distal end of the sleeve part, the upper clamp part and the lower clamp part are divided into left and right two parts, one part is an anastomosis component, and the other part is a purse string suture component, the upper clamp part and the lower clamp part are provided with sliding ways extending from the proximal end to the distal end on the upper and lower sides, a pressing block is arranged between the distal end of the sleeve part and the proximal end of the lower clamp part, the pressing block can move along the sliding way, the proximal end first section and the distal end second section of the upper clamp part and the lower clamp part are connected through a slope, the opening angle and the pressing of the upper clamp part can be controlled when the pressing block moves on the sliding way, a driving rod is arranged in the sleeve part, two purse string needles extending along the direction of the proximal end and the distal end are arranged on one side of the driving rod, and the two purse string needles pass through the clamp teeth when the cutting purse string suture assembly is closed. The application has the advantages of simple structure, convenient operation, easy cutting and suture control.

The invention discloses an auxiliary purse-string suturing device for peritoneal dialysis catheterization, and relates to the field of peritoneal dialysis catheterization, the auxiliary purse-string suturing device comprises a mounting mechanism, the mounting mechanism comprises a mounting main rod, the surface of the mounting main rod is provided with an adjusting groove, the surface of the adjusting groove is provided with an adjusting mechanism, the adjusting mechanism comprises an adjusting ring and a fixing ring, and the fixing ring is provided with a fixing groove. The adjusting ring and the fixing ring are both sleeved with an adjusting groove in the surface of the mounting main rod, the fixing ring is fixedly connected with the adjusting groove, and the adjusting ring is slidably connected with the adjusting groove. According to the auxiliary purse-string suturing device for the peritoneal dialysis catheterization, the edge of the flexible protective skin is tightly buckled on the inner surface of the peritoneum, so that an intestinal canal and the omentum majus are isolated outside a suturing area, a closed compartment is established, medical staff can conveniently conduct peritoneal purse-string suturing in the protection area of the flexible protective skin, the risk of secondary injury is reduced, and the operation is convenient. And the opening size of the flexible protective leather can be flexibly adjusted, so that the device is suitable for auxiliary work of purse-string suture with different opening sizes.
