摘要:
A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

An apparatus for determining an angle of a handle of a pipe bender includes a sensor configured to determine an orientation angle of the sensor and a display configured to display the orientation angle of the sensor. The apparatus further includes a housing configured to attach to the handle of the pipe bender. The sensor is within the housing.

The conduit marking device comprises a slotted, marked measuring handle for a conduit bender. The measuring handle may be a replacement for the handle provided with the conduit bender. The measuring handle of the conduit marking device provides the ability to easily measure, mark, and align conduit in order to obtain precise results for the bends. The measuring handle is hollow and tubular and a piece of conduit may be inserted into the measuring handle from one end of the handle. The measuring handle incorporates slots, which allow the conduit to be seen through portions of the handle. Measuring indicia on the measuring handle allow specific locations on the conduit to be located and the locations may be marked through the slots on the measuring handle.
摘要:
A surgical instrument comprising an implant bending device including a mating part such that the implant bending device is interchangeable with a bending module and a cutting module. The bending module having work surfaces engageable with a spinal implant to manipulate the spinal implant to a selected implant configuration. The cutting module is engageable with the spinal implant having the selected implant configuration. Systems, surgical instruments, spinal constructs, implants and methods are disclosed.

A conduit tube bending tester for use in testing potential measurements, angles and placements of a EMT conduit to be bent prior to permanently bending the EMT conduit includes a core member defining a elongated cylindrical wire constructed of a thin metal and a tubular outer body defining an exterior coating or skin constructed of a resilient material, with the core member enclosed in the outer body. Being embodied as a wire, the core member has the ability to be bent at any point along its length in any direction through the application of external force and retain the bend unless and until it is straightened or re-bent in another direction through application of external force. The outer body may additionally include a plurality of markings which define standardized measurements.

An implantable rod can be bent three-dimensionally in an automated system, which is especially useful for pre-surgical formation of implantable spinal rods. When local and/or global feedback processing accompanies a series of shaping steps automatically imposed on a rod or other article being shaped into three-dimensional form, formation time may be expedited compared to manual creation, and shapes difficult or impractical to create manually may be constructed simply.

A swaging system includes a swaging assembly, a sensor, and a controller. The swaging assembly includes a movable tool, the movable tool operate to exert force on a die. The die is configured to reduce a dimension of a work piece responsive to the exerted force, the dimension reduction having a relationship to a stroke of the movable tool. The sensor is operable to obtain information including a measurement of the reduced dimension of the work piece. The sensor is operable to generate a measurement signal representative of the obtained information. The controller is operably coupled to receive the measurement signal from the sensor, and is operable to cause adjustment the stroke of the movable tool responsive to the measurement signal.
