A medical device system configured to dynamically switch motor control protocols while a motor within a handheld device is operating to increase efficiency of the motor operation and to provide improved reliability and performance is disclosed. In at least one embodiment, the medical device system may be configured to dynamically switch motor control protocols while the motor is operating based on input from one or more sensors configured to monitor a motor, including, but not limited to, monitoring a magnetic flux field of the motor or monitoring current to the motor. The medical device system may dynamically switch motor control protocols between motor control protocols, including, but not limited to, Six-Step Commutation, Hall-Based Sinusoidal Commutation and Field Oriented Commutation.

A universal wire driver attachment comprises a driveshaft forming a lumen extending along a longitudinal axis. The driveshaft forms a plurality of channels extending perpendicularly from the longitudinal axis. The attachment further comprises a plurality of primary jaws movably disposed at least partially within the channels. The primary jaws comprise a plurality of wire gripping surfaces facing the longitudinal axis and configured to grip the surgical wire. The primary jaws cooperate with the channels such that the primary jaws are constrained from moving in an axial direction along the longitudinal axis. The primary jaws are capable of moving outward from the longitudinal axis when the surgical wire is inserted between the primary jaws, and the primary jaws are capable of being urged inward toward the longitudinal axis by the securing mechanism to increase a grip force on the surgical wire.

The disclosed subject matter relates to a visual guide for aiding the surgeon in the insertion of a k-wire. The guide including a ring for receiving a guide wire, the guide wire extending from the ring parallel to the center axis of the ring; and, a ring attachment mechanism configured to attach the visual guide to a wire driver. The guide wires representing the trajectory of the k-wire in two orthogonal planes thus allowing the surgeon to free hand the insertion by visually referencing the guide wires and the actual trajectory of the k-wire within the bone.

A robotic surgical system may be used to perform a surgical procedure. Providing guidance for the robotic surgical system includes integrating a Point of View (PoV) surgical drill with a camera to capture a PoV image of a surgical area of a subject patient; displaying an image of the surgical area, based on a viewing angle of the PoV surgical drill, thus enabling the surgeon to operate on the surgical area using the PoV surgical drill. The PoV surgical drill operates based on the surgeon's control of a guidance drill. The content of the images may change based on a change in the viewing angle of the PoV surgical drill.

An integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, an output assembly, and a plurality of planetary gears each having a plurality of gear teeth. The shaft assembly is configured to cause rotation of the planetary gears with a sun gear. The rotation of the planetary gears is configured to cause rotation of an output shaft, with a reduction of rotational speed relative to the rotation of the shaft assembly.

A medical device for penetrating a bone structure including a processing unit having a transfer function that associates an electrical conductivity value S with a depth value d, wherein the processing unit is configured to detect a threshold selected from amongst an absolute threshold, a relative threshold and a critical gradient, and to emit a warning signal and/or control signal responsive to detection of the threshold.

A bone biopsy system includes a stylet, a trephine needle, a drive connector and a push rod. The trephine needle includes a lumen and a cutting edge. The stylet is received in the lumen to set the trephine needle in position for procuring a bone core sample. The stylet is then removed and the trephine needle is driven into the bone to collect a bone core sample in the lumen.

In general, data modules for surgical instruments and methods of using data modules for surgical instruments are provided. In an exemplary embodiment, a data module is configured to be removably attached to a powered surgical tool such as an electrosurgical tool. The data module is a standalone device including electronic components that are configured to, with the data module attached to the electrosurgical tool, interact with the electrosurgical tool.

A method includes providing a handheld manipulator, a surgical tool coupled to the handheld manipulator, and a mechanical arm, affecting, with the handheld manipulator connected to the mechanical arm, motion of the surgical tool by operating a motor of the handheld manipulator, and affecting, with the handheld manipulator disconnected from the mechanical arm, the motion of the surgical tool by operating the motor of the handheld manipulator.

The present disclosure relates to a lateral sleeve pipe drill and a operating method, belong to the field of surgical instrument technologies, and solves the problems that a bone passage cannot be effectively corrected and is liable to be corrected excessively, and correction is time-consuming and damages important functional bone tissue morphology. The lateral sleeve pipe drill is of a hollow cylindrical shape and includes a first end and a second end. An outer wall of the first end is provided with a correction portion for correcting the bone passage. The first end is arranged in a human body and is of a particular shape adapted to different surgical methods, a surgical approach direction, and a human body internal structure.
