Abstract

The invention provides minimally-invasive surgical forceps. The minimally-invasive surgical forceps comprise an executing portion, a driving portion and a holding portion, wherein the executing portion comprises a forceps head and a flexible joint, the flexible joint is connected to the forceps head and can drive the forceps head to move, the driving portion connected to the executing portion comprises a joint driving structure driving the flexible joint to move, and the holding portion is connected to the driving portion, is in linkage with the joint driving structure and can drive the jointdriving structure to move when swinging so as to drive the flexible joint to move and enable the forceps head to deflect. The holding portion can control the forceps head to open and close and can also control the forceps head to deflect, and accordingly operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a minimally invasive surgical forceps. Background technique [0002] Minimally invasive surgery is the most cutting-edge development direction of medical science and technology today. Because of its small surgical trauma, mild postoperative pain, short hospital stay, and good cosmetic results, it has been widely used in clinical practice with satisfactory results. Due to the limited degrees of freedom of traditional minimally invasive surgical instruments, which do not have degrees of freedom in pitch and yaw, they are clumsy and have poor dexterity, which seriously affects the quality and accuracy of surgery. [0003] Chinese patent document CN105361924A discloses a kind of surgical control universal surgical forceps, especially a kind of manual control universal minimally invasive surgical forceps, including a base, a forceps rod, and a forceps head. The forceps hea...
