Abstract

The invention provides a bionic minimally-invasive surgical clamp for treating thoracolumbar burst fracture. The bionic minimally-invasive surgical clamp comprises a crocodile skull simulation structure formed by combining two-side arched beams, a middle longitudinal beam, two-side slight projections and a wing-shaped supporting arch of an upper clamp body, and accordingly stress and strain of the clamp under load can be reduced obviously, and structural strength of the clamp is improved greatly. Toothed microstructures at clamping ends of the upper clamp body and a lower clamp body simulate distribution and structural characteristics of teeth of a crocodile, so that clamped objects can be prevented from slipping off. The bionic minimally-invasive surgical clamp for treating thoracolumbar burst fracture is small in size, compact in structure, high in structural strength and clamping reliability, capable of reducing misoperation during surgery and beneficial to smooth operation of the surgery.

Description
