Adaptive clamping device and clamping method for irregular objects

Abstract

The invention belongs to the field of medical apparatus, and discloses an self-adaptive clamping device for an irregular object. The self-adaptive clamping device includes a positioning platform, anda flexible clamping mechanism, the flexible clamping mechanism comprises a flexible fixture bracket and a plurality of flexible fixtures connected in parallel, each flexible fixture comprises a springmounting rod, a spring and a pressing disc, and one end of each spring mounting rod is movably mounted in the flexible fixture bracket; and the other end of each spring mounting rod is hinged to thecorresponding disc so that the corresponding pressing disc can swing around the hinge center, and the springs are externally arranged on the spring mounting rods in a sleeving mode and placed betweenthe flexible fixture bracket and the pressing discs so that the springs generate the self-adaptive pressure to the flexible fixture bracket and a hinging rotating shaft when the spring mounting rods move in the flexible fixture bracket. The self-adaptive clamping device further includes a position adjusting mechanism and a cutting mechanism except the flexible clamping mechanism and aims to solvethe technical problems that large elastic deformation or even yield deformation and invalid clamping are easily produced during clamping of the irregular object, especially, the elastic textures.

Description

technical field [0001] The invention belongs to the field of medical devices, and more specifically relates to an adaptive clamping device and a clamping method for irregular objects. Background technique [0002] At present, the clamping device used for objects with irregular shapes generally selects multiple constraint points or force application points on the surface of the object, and then adopts a rigid contact method for clamping. For irregular objects, including elastic tissues, the rigid contact clamping method brings many disadvantages, including: the number of constraint points is difficult to artificially select; it is not universal: if the shape of the clamped object changes, the fixture needs to be redesigned; lack of flexibility : If the clamping force is insufficient, irregular objects are difficult to fix; if the clamping force is too large, irregular objects, especially elastic tissues, are prone to excessive elastic deformation or even plastic deformation. ...
