Industry Trends The shift from open cavity procedures to minimally invasive procedures has already occurred within the United States, Australia and Europe. For hospitals to attract top talent, they must be equipped with the latest in high-tech equipment and facilities in order to increase efficiency for the surgeon. Incorporating surgical navigation and robotic systems into
Image guided surgery (IGS) assists ear, nose and throat (ENT) specialists in performing interventions where the shape of the sinus and airways can cause potential complications. The majority of ENT IGS systems are designed for ENT procedures only. However, some companies who do not manufacture a standalone ENT IGS system will bundle their ENT software with cranial software. Lacking some of the specialized features designed for neurosurgery procedures, ENT systems are relatively simple and less expensive. However, ENT procedures are more difficult to visualize than other IGS procedure types as they involve much smaller and hard to reach areas of the human body.
Neurosurgery navigation, or neuronavigation, requires the use of computer-assisted technologies to guide or navigate neurosurgeons during cranial procedures. This type of surgery evolved from stereotactic surgery, which gained popularity during the 1940s. Stereotaxy was developed to better locate specific small targets within the patient using a three-dimensional coordinate system. IGS was initially developed in the neurosurgical field to assist in accurately navigating the path to tumors in sensitive cranial areas. Many neurosurgical procedures could not be performed without the aid of some kind of a navigation system. As a standard of care procedure, IGS systems have a high penetration rate in the neurosurgical market, with most facilities that perform neurosurgery already having a system. As a result, neurosurgical IGS products have the highest proportion of expert surgeons using these devices. The neurosurgery IGS market is primarily a replacement market, with some new sales going to facilities that may require an additional system.
Orthopedic image guided surgery (IGS) systems are used in procedures such as total knee arthroplasty (TKA), total hip arthroplasty (THA), anterior cruciate ligament (ACL) reconstruction, trauma and corrective surgeries. During these reconstruction procedures, the alignment of the orthopedic implant is critical and IGS systems are capable of reaching the target alignment within +/- 3°, 95% to 98% of the time.
The market for spine navigation systems, or spinal image guided surgery (IGS) systems, is closely linked to that of neurosurgical IGS systems. There are relatively few dedicated IGS systems for spinal procedures. Most spinal IGS procedures are performed using neurosurgical IGS systems with spinal software applications. Because spinal and neurosurgical operations are often performed by the same surgeons, this arrangement has worked well so far. Certain spinal procedures may require specialized instruments; however, these disposable instruments can be used with non-specialized systems that have the appropriate software. Many spinal IGS systems can be used to assist in trauma procedures once equipped with the right software and accessories. Spinal conditions treated with IGS include fractures, metastasis, spinal slip disc and spinal curvature. Spinal imaging software allows surgeons to perform on the thoracic and lumbar regions of the spine, while many have pelvic trauma applications. Recently, there has been a push to develop more dedicated spinal IGS and robotic systems that would be better suited to strictly spinal or trauma surgeries.
Surgical robotics has tremendous potential to increase the effectiveness of existing procedures and to facilitate novel procedure types. The surgical robotics industry is, in many ways, still in its infancy, with more products in development than currently commercially available on the market. Early surgical robotics systems were based on industrial robots; however, most new surgical robotic systems are designed for highly specialized medical applications, which is a major drawback for most facilities. The types of surgical robotic assisted systems covered in this section are minimally invasive surgery robotic systems, orthopedic robotic systems, spinal robotic systems, neurosurgery robotic systems, robotic catheters and radiosurgery robotic systems.
