Degradable inward-turning annular pressure type biological tube anastomat

Abstract

The invention relates to a degradable inward-turning annular pressure type biological tube anastomat. The anastomat comprises an anastomat bottom, wherein the anastomat bottom is in threaded connection with one end of an anastomat guide rail, and the other end of the anastomat guide rail is cooperatively connected with a top hole axis of the anastomat; the anastomat bottom comprises a first ring, one side of the first ring is connected with a first cylinder with an internal thread, the other side of the first ring is provided with first metal nails and first anastomosis holes both of which are uniformly distributed, and the first metal nails and the first anastomosis holes stagger with each other; an anastomat top comprises a second ring, one side of the second ring is connected with a second cylinder internally provided with an outer convex edge, the other side of the second ring is provided with second metal nails and second anastomosis holes both of which are uniformly distributed, and the second metal nails and the second anastomosis holes stagger with each other; one end of the anastomat guide rail is provided with an external threaded section matched with the internal thread of the first cylinder, and a groove matched with the outer convex edge in the second cylinder is arranged outside the other end of the anastomat guide rail, and a clamping slot is formed in the groove. The anastomat enables the edges of a wound to heal at the same time in a week, and the healing speed is high; the anastomat can be degraded in a biological tube.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a degradable inversion ring-pressure biological tube stapler. Background technique [0002] Human biological tube repair is a basic operation type in surgery, and the port-to-port anastomosis of biological tubes (end-to-end anastomosis) accounts for a large proportion of human biological tube repair operations. In the operation, end-to-end anastomosis is usually done after the biological tube is processed, and the free ports on both sides are sutured together with absorbable sutures; or the side port is cut from the side of the biological tube that is closer to the lesion and placed Disposable stapler, one end of the stapler is connected to the free upper incision, the other end is connected to the free lower incision, through the external mechanical knob, the force is applied slowly to make the free two ends of the incision anastomosis, and use metal staples; multi-row c...

Problems solved by technology

Therefore, the wavy pressure distribution method, that is, the use of absorbable thread or titanium nails for anastomosis, anastomotic leakage or inconsistent wound healing time in a week will lead to a decline in the healing effect.
