Titanium nail of anastomat

Abstract

The invention discloses a titanium nail of an anastomat. The titanium nail of the anastomat comprises a nail base (1) and nail legs (2) arranged at the two ends of the nail base (1). The upper end of each nail leg (2) is provided with a nail tip (2-2); the upper part of each nail leg (2) is provided with an arc part (2-1); each nail tip (2-2) is bent inwards; and an inward bending angle alpha is 6 degrees to 8 degrees. The design of the titanium nail of the anastomat disclosed by the invention improves probability of titanium nail formation, reduces resistance of the titanium nail formation and guarantees stability of the titanium nail formation.

Description

technical field [0001] The invention relates to a stapler titanium nail, which belongs to the field of medical instruments. Background technique [0002] At present, the existing clinical titanium nails are all of an inverted trapezoidal design, so when the titanium nails are pushed out of the nail cartridge, they also come out in the shape of an inverted trapezoid. Since the inverted trapezoid is an outward trend, it is easy to cause the titanium nails to bend outwards. , and because the forming grooves of the anvils are all concave, so that the titanium nails will be out of shape first and then inward, resulting in incomplete anastomosis and bleeding of patients. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a stapler titanium nail whose tip is bent inward and can reduce the forming resistance of the titanium nail. [0004] The technical solution for realizing the object of the prese...

[0002] At present, the existing clinical titanium nails are all of an inverted trapezoidal design, so when the titanium nails are pushed out of the nail cartridge, they also come out in the shape of an inverted trapezoid. Since the inverted trapezoid is an outward trend, it is easy to cause the titanium nails to bend outwards. , and because the forming grooves of the anvil seat are all concave, so that the titanium nails will not be formed first and then inward, resulting in incomplete anastomosis and bleeding of the patient.
