Hemostatic forceps for liver tissue resection

Abstract

The invention discloses a hemostatic forceps for liver tissue resection, which comprises a first forceps, a first arc-shaped groove is opened on one side of the forceps head of the first forceps, and a first arc-shaped groove is formed on the side of the forceps head of the first forceps. For the second tongs, the rotating column runs through the first tongs and the second tongs and is rotationally connected with the first tongs and the second tongs. One side of the tong head of the second tongs is provided with an arc connected to the first tongs. A second arc-shaped groove that matches the groove, the first side of the pincer head of the first pincer is provided with a first transverse tooth groove parallel to the first pincer, and the side of the pincer head of the second pincer is opened There is a second transverse cog matching the first transverse cog, and the part of the first clamp located on the right side of the rotating column is fixedly connected with a first return spring. The present invention relates to the technical field of medical instruments. The hemostatic forceps for liver tissue resection can prevent blood vessels from sliding in both horizontal and vertical directions during use, and have good fixing effect during clamping, and are not easy to slide away.
