Operating forceps with force/position sensing function and force-position decoupling system

Abstract

The invention provides operating forceps with a force/position sensing function and a force position decoupling system.The operating forceps comprise the force position decoupling system, a grip, two connecting rods, an upper clamp assembly, a lower clamp assembly and a displayer, the two connecting rods are connected to the two ends of the grip respectively, and the upper clamp assembly and the lower clamp assembly are erected on the two connecting rods respectively; the upper clamp assembly and the lower clamp assembly are provided with a force position detection fiber bragg grating and a temperature compensation fiber bragg grating respectively, and the force position detection fiber bragg grating and the temperature compensation fiber bragg grating are connected with the displayer through a force position decoupling system. By means of intelligent algorithm processing, force/position information can be transmitted to a displayer in real time, a doctor can conveniently use the information to control the gripping force when an object is grabbed, and the position, where the grabbed object is located, of the clamp can be detected.

Description

technical field [0001] The invention relates to the technical field of surgical equipment, in particular to a force / position sensing function surgical forceps and a force-position decoupling system. Background technique [0002] In general open, laparoscopic and robot-assisted surgery, clamping is the most common operation method. However, the objects to be clamped such as human tissues and organs are generally soft, so it is easy to be overloaded during the clamping process. The force causes the group organ to rupture. [0003] It is understood that in laparoscopic cholecystectomy, one of the most mature surgical procedures at present, 56% of surgical errors are caused by the force being too large or too small. Excessive force applied during surgery can cause tissue damage, while insufficient force can lead to tissue slippage, which also involves issues with the position of the tissue in the clamp. Therefore, it is particularly important to introduce force / position detect...
