NEUROLOGICAL SURGERY

Our advanced models simulate all critical elements of a specific procedure. The materials included have biomechanical characteristics similar to those of human tissue, and behave in a similar manner during cutting, manipulation, suturing, and electro-cautery. Relevant anatomical elements are included for brain, spine, and peripheral nerve procedures. The advanced trainers have full medical imaging compatibility (CT scan, 2-dimensional and 3D ultrasound) and simulate true operative metrics of performance (blood loss, tumor margins, operative and ischemia time, amongst others). Please contact us for product and pricing information.

Intracerebral Hemorrhage Phantom

Full procedural trainer for minimally invasive evacuation of ICH from the brain. Plastic skull base containing hydrogel brain with two hematomas. Additional elements include synthetic frontal bone, dura mater, venous sinuses, and scalp that requires pre-procedural planning, incision, and burr hole procedure for entry. Supplied with CT scan to enable image registration and stereotactic navigation.

Myelomeningocele

The myelomeningocele simulator permits full procedural training from incision to multilayer closure. These models contain non-viable tissue that requires resection,  pseudodura that needs to be mobilized, a neural placode that can be imbricated, and allows trainees to attempt watertight closure of dura, fascia, and skin. 

Carotid Endarterectomy

Full procedural carotid endarterectomy simulator. 

Cervical Laminectomy Simulator

Operations near the spinal cord need to be performed with great care to prevent disastrous complications. This cervical decompression model provides rehearsal of posterior approaches to the spine, from palpation of boney landmarks to closure of fascia and skin. This realistic bleeding simulator contains multilayer soft-tissue elements with multiple bleeding points. In addition, there is an incorporated pressure sensor that permits the measurement of impact to the thecal sac during ronguer and drill use. 

Peripheral Nerve Tumors

Simulation of peripheral nerve sheath tumor resection is very important given the relative rarity of disease and high potential morbidity if improper surgical technique is utilized. These extremity simulators include surrounding fascia, muscle, tendons, ligaments, bone, and pertinent nerves depending on surgical goals.

This video demonstrates a sciatic nerve resection simulator that incorporates electrophysiological monitoring and permits the use of a nerve stimulator to find functional fascicles.

Imaging-Compatible Brain Tumor Phantom

Training phantom for the realistic resection of brain tumors from the cerebral cortex. Consists of a synthetic brain with 4 tumors made of realistic material within the cerebral cortex, contained within a plastic skull base with ports of entry for tumor access. Tumors are compatible with fluorescent endoscopic imaging (see image at right). MRI DICOM files supplied to enable registration and stereotactic navigation. 

SIM is currently developing and commercializing phantoms for the following procedures:
