In order to promote research on hotspots in microsurgery and hand surgery, and strengthen academic exchanges, under the guidance of the Zhejiang Provincial Continuing Education Office, a provincial continuing education project “Microsurgery Operation New Technology Learning Class” was held in the Longshan Branch of Ningbo First People’s Hospital of Zhejiang Province. The class lasted from June 28 and 30 and had 50 participants. In this class, the college mainly studied the separation of the blood vessels and nerves of the mice under the microscope, the lateral opening of the blood vessels and the end-to-side anastomosis. During the class, each student used disposable dissectors to perform lateral opening and blood vessel separation on the blood vessels. They said the disposable dissector of our company is small, sharp and easy to use.
