A training simulator for intraoperative neuromonitoring (IONM) systems includes channels where at least one of the channels is identified as an active stimulation channel and a subset of the rest of the channels is identified as reference or pick up sites. Channels of the subset having signal data that exceed a predefined threshold are retained for further processing, while channels with signal data that do not exceed the threshold are eliminated from further reporting. Response data for the remaining channels are generated in advance of a future time when the response would occur. The generated data is time stamped and stored for display at a time window when requested by the system.

A radial head trial device for replacement of a proximal radial head includes a stem component having a center longitudinal axis extending between a proximal end and a distal end, a head component axially and removably attachable to the stem component, wherein the head component is interchangeable with a selection of other head components each axially and removably attachable to the stem component, an anti-rotation feature, and a recess, wherein the anti-rotation feature is structured to be received in the recess to prohibit rotation of the head component relative to the stem component.

Some embodiments provide systems, assemblies, and methods of analyzing patient anatomy including providing an analysis of a patient's spine. The systems, assemblies, and/or methods can include obtaining initial patient data, and acquiring spinal alignment contour information. Further, the systems, assemblies, and/or methods can assess localized anatomical features of the patient, and obtain anatomical region data. The system, assemblies, and/or method can analyze the localized anatomy and therapeutic device location and contouring. Further, the system, assemblies, and/or method can output localized anatomical analyses and therapeutic device contouring data and/or imagery on a display.

An apparatus for training suturing techniques. The apparatus comprises: (i) a suturing cartridge presentation display with a first receptacle for demountably engaging therein a first suturing cartridge and a second receptacle for demountably engaging therein a second suturing cartridge, (ii) a microprocessor, a graphical user interface, and at least one software program for cooperating with the microprocessor for training, monitoring, reporting suturing techniques; and (iii) a housing for mounting therein the suturing cartridge presentation display, the microprocessor, and the graphical user interface. Each receptacle is associated with a pressure sensor and a plurality of LEDs. The suturing cartridges are fillable with semi-solid, resilient material into which suturing instruments may be inserted and withdrawn. The pressure sensors detect movements associated with manipulation of suturing instruments, while the LEDs provide guidance to suturing tasks and visual cues relating to acceptable and unacceptable manipulation of suturing instruments.

The pimple-popping simulator is an apparatus that allows a user to practice popping pimples without directly popping a real pimple. The apparatus includes a pliable body, at least one channel, and a quantity of discharge-like filling. The pliable body mirrors supple skin. The at least one channel mirrors a pore. The quantity of discharge-like filling represents the dead skin cells, oils, and bacteria clogged within the pore. The at least one channel further includes a first edge, a second edge, a lateral wall, and a reservoir. The first edge defines a main opening. The second edge prevents the quantity of discharge-like filling from escaping unless the proper force is applied. The lateral wall defines an exit for the quantity of discharge-like filling. The lateral wall preferably tapers from the second edge to the first edge, thereby mirroring the popping of pus of a pimple as a result of pressure.

A neurosurgical endoscopic training system and method for using the system to develop surgical skills and technical competency of an endoscopist. The system includes a portable part-task enclosure with a plurality of walls defining an internal chamber. One of the walls includes an access port coupling the internal chamber to an external environment and the access port can be configured to facilitate the passage of one or more endoscopic surgical tools. The system further includes a plurality of objects disposed within the internal chamber configured for manipulation by a surgical tool that extends through the access port.

An electro-anatomical model of the mammalian His/Purkinje system includes a shell simulating the anatomy of at least a portion of a mammalian heart. The shell has a hollow interior and a first port providing an aperture to the interior of the shell. A plug is inserted in the first port so that a surface of the plug is exposed to the interior of the shell. An electrical circuit provides signals to electrodes in the plug which simulate the electrical signals generated by the bundle of His/Purkinje system in vivo. A second port provides access to the interior of the shell for an introducer catheter to locate the simulated bundle of His and to insert a pacing lead therein. The model is useful for developing tools for His pacing and for training users in techniques for implanting His pacing leads.

A surgical training model can have features for training surgical suturing techniques. The training model can be formed as a sheet of simulated tissue having at least one cut with markings arranged on either side of the cut. The markings can be formed of a first layer of resilient simulated tissue material having a color that contrasts with a color of the remainder of the sheet of simulated tissue material. The sheet of simulated tissue material can have several cuts having different configurations and orientations to facilitate suturing training for a variety of tissue orientations. The sheet of simulated tissue material can further include holes positioned to be mounted to a base of a surgical training system. The sheet of simulated tissue material can be manufactured by molding a marking layer and casting a tissue layer over the marking layer.

System and methods for simulating a surgical procedure are provided. The system includes a non-transitory computer-readable medium including instructions, which when executed by one or more processors, are configured to execute a surgical planning program. The surgical planning program is configured to track a tool relative to a model of an anatomy during a preoperative surgical simulation, generate a planning parameter based on the tracking of the tool relative to the model of the anatomy during the preoperative surgical simulation, and store the generated planning parameter. The system also includes a surgical system configured to load the generated planning parameter from the surgical planning program, and facilitate intraoperative surgery based on the generated parameter.

Disclosed are adjustable powered rehabilitation devices and methods for using the same to rehabilitate and/or train a user. The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.
