Title:
SURGICAL INSTRUMENT FORCE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/082354
Kind Code:
A1
Abstract:
A surgical instrument force detection device, comprising a fixed support (10), a first detection unit (20), a second detection unit (30) and a stamping member (40). The first detection unit (20) and the second detection unit (30) are both mounted on the fixed support (10); the first detection unit (20) can fix epidermal tissue, and the first detection unit (20) comprises a first force sensor (222), and the first force sensor (222) can detect the force or torque exerted on the epidermal tissue by the stamping member (40); the second detection unit (30) can fix internal tissue, and the second detection unit (30) comprises a second force sensor (321), and the second force sensor (321) can detect the force or torque exerted on the internal tissue by a surgical instrument; and the stamping member (40) is hollow and the surgical instrument can pass therethrough, and the stamping member (40) can pass through the epidermal tissue fixed by the first detection unit (20) and enable the surgical instrument to make contact with the internal tissue fixed by the second detection unit (30). The surgical instrument force detection device can simulate the forces applied to epidermal tissue and internal tissue during a minimally invasive surgical operation, facilitating the optimization of a movement path and the size of a force.
