MULTIFUNCTIONAL WIRELESS DEVICE WITH REPLACEABLE SURGICAL INSTRUMENTS FOR MEASURING THEIR ORIENTATION ANGLES IN SPACE AND FORCES AND MOMENTS AFFECTING THEM DURING NEUROSURGICAL OPERATIONS Russian patent published in 2023 - IPC A61B17/00 A61B17/34 A61B34/20 

FIELD: medical equipment.

SUBSTANCE: invention relates to devices and surgical instruments used in neurosurgery for work related to cutting holes in soft tissues, as well as installing or removing internal fixation devices. A wireless device for measuring orientation angles and determining the forces and moments acting on interchangeable surgical instruments during neurosurgical operations includes a hollow handle for manual operations containing a rechargeable battery for powering all electronic parts, a housing inside which is installed a six-axis inertial orientation sensor based on a gyroscope and an accelerometer, controller, signal processing module from a six-axis force and torque sensor and an external control board with a control button and LED. A six-axis force and moment sensor is attached to the end part of the body, on which a flange and a threaded removable holder with buttons are installed, allowing for quick change of surgical instruments during surgery. A six-axis force and moment sensor and a six-axis orientation sensor are connected to a controller in the housing, which, in turn, is connected via a wireless interface to the device control unit for wireless connection, control and reception of data by the user’s personal computer with the ability to record and display data in graphical, audio and light form with visual indication when the maximum specified manipulation parameters are exceeded.

EFFECT: obtaining quantitative data on the orientation angles in space of surgical instruments, forces and moments arising from the manipulation of surgical instruments during a neurosurgical operation.
