Problems solved by technology

This long-term operation often leads to fatigue and spasm of the operator's internal muscles. As a result, the operator's hand trembles, the stability of the operation decreases, and it can also cause local damage to the clamped tissue, resulting in a decrease in the surgical effect.

Abstract

The invention relates to a microsurgical pen used for performing a vascular anastomosis process when vascularized tissues and organs are subject to transplantation. The microsurgical pen comprises a pen point with an anastomosis tip and a refill moveably connected with the pen point; and the opening and the closing of the anastomosis tip of the pen point are controlled by the refill. The microsurgical pen is simple in structure, reasonable in design, and convenient to operate; the comfort and the accuracy of the operation can be increased, the operation difficulty is reduced, the operation efficiency and the success rate of anastomosis are improved; and furthermore, the microsurgical pen is beneficial for popularizing and improving the microsurgical operation on a large scale.

Description

technical field [0001] The invention belongs to medical instruments, and relates to a surgical instrument, in particular to a microsurgical pen used for blood vessel anastomosis when transplanting tissues and organs with vascular pedicles. Background technique [0002] Microsurgery is the subject of fine surgery by using optical magnification equipment and microsurgical equipment. Optical magnification equipment and microsurgical equipment are important conditions for its rapid development. Over the past half a century, based on the gradual improvement of these two conditions, microsurgery has developed rapidly at home and abroad, and has surpassed the scope of disciplines. As an advanced surgical technique, it has been widely used in various clinical departments. [0003] Proficiency in the application of microinstruments is essential for microsurgeons. However, this technology is still mainly carried out in large hospitals, and its widespread popularization in hospitals ...
