Problems solved by technology

Moreover, during the surgical cutting process, the tissue displacement and deformation are large, resulting in the incision of the epidermis or muscle fibers, which does not conform to the physiological cutting conditions in real surgery, so the real surgical operation process cannot be simulated.

Abstract

The invention provides a soft tissue biomechanical parameter measuring method and system. The method comprises the following steps: (1) clamping and fixing a soft tissue to be measured in a fixed clamping plate, and fixedly connecting the fixed clamping plate with a dynamometer; (2) controlling a surgical blade through a probe, and carrying out puncture and cutting operations on the soft tissue tobe measured along a preset feeding path; (3) acquiring and recording the magnitude and change of the stress of the soft tissue to be measured through the dynamometer so as to obtain a puncture forcecurve and a cutting force curve; and (4) updating the soft tissue to be measured, and repeating the steps (1)-(3) to obtain biomechanical parameters of different soft tissues of the maxillofacial region. According to the method, the cutting process in the real operation process can be simulated, biomechanical parameters such as puncture force and cutting force of different tissues of the maxillofacial region are obtained, and a foundation is laid for construction of a subsequent soft tissue force tactile feedback model.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method and system for measuring soft tissue biomechanical parameters. Background technique [0002] Virtual reality (virtual reality, referred to as VR) technology has great development in the medical field due to its interactivity, immersion, and conception, and has broad development prospects. Surgical teaching and operation training can be carried out by using VR technology. In order to realize image and haptic feedback in virtual surgery, physical modeling of soft tissue is crucial. [0003] In order to establish a real-time and realistic soft tissue model that conforms to biomechanical characteristics, it is necessary to measure the corresponding biomechanical physical parameters of different soft tissues to realize soft tissue virtual surgery. The measurement of the corresponding mechanics-related physical parameters of soft tissue needs to build a soft tissue b...
