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.

Embodiment Construction

[0028] The present invention provides a microsurgery pen. The microsurgery pen includes a pen tip 1 with an anastomosing lip 11 and a pen core 2 movably connected with the pen tip 1; the pen core 2 controls the opening and closing of the pen tip 1 anastomosing lip 11, The present invention transfers the anastomotic lip 11 completely controlled by the thumb and index finger to the pen core 2 to control the opening or closing, which effectively overcomes the in-hand caused by the long-time holding of the existing microscopic instrument during use. Disadvantages such as muscle fatigue and cramps.

[0029] The pen head 1 includes an anastomosis lip 11, a movable joint 12, and an elastic wire 13; the anastomosis lip 11 is connected to the elastic wire 13 through the movable joint 12; the elastic wire 13 is movably connected to the pen core 2; the anastomosis lip 11 is in a close state in a resting state The elastic wire 13 is in a long shuttle shape in a static state; the pen core 2 p...

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 a medical instrument, and relates to a surgical instrument, in particular to a microsurgery pen used for vascular anastomosis during transplantation of tissues and organs with vascular pedicles. Background technique [0002] Microsurgery is the subject of fine surgery by using optical magnification equipment and microsurgery equipment. Optical amplification equipment and microsurgery equipment are important conditions for its rapid development. For half a century, it is precisely based on the gradual improvement of these two aspects that 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 by various clinical departments. [0003] Proficiency in the application of microscopic instruments is essential for microsurgeons. However, this technology is still mainly carried out in large hospitals, and its widespread popularity in hospit...
