There are three main types of capital equipment associated with the power shaver market: (1) shaver consoles, (2) hand instruments and (3) footswitches. Hand instruments typically have a lifespan of two to three years. This comes in contrast to shaver consoles and footswitches, which have an average lifespan of about five years. On average, each shaver console uses two to three hand instruments. In comparison, one footswitch is generally used per shaver console. Shaver consoles, hand instruments and footswitches are typically provided at no cost in exchange for long-term disposable blade contracts.
Drill guides are used during the reconstruction of the ACL and PCL. As the name implies, these devices are used for properly aligning the drill bit for the precise creation of tunnels and holes in boney surfaces. The knee is one of the most susceptible joints to pressure and injury in the human body, as its bending capacity is determined by a complex interaction of rotational and extensional movements. The anterior and posterior cruciate ligaments (ACL/PCL) connect the bones that form the knee and stabilize joint movements to prevent the femur from sliding against the tibia and vice versa.
Injuries to the ACL are quite common. These injuries can be caused by excessive use, physical impact or wear over time. Usually, during ACL/PCL reconstruction, the surgeon drills holes in the tibia in order to hold harvested patellar tendon with fixation devices such as staples and screws, thus reconstructing the ligament.
The full report suite on the U.S. market for arthroscopic devices includes arthroscopes, disposable cannulas, hand instruments, fluid management disposables, shaver blades, radiofrequency (RF) probes, drill guide systems and disposables and suture passers. Power instruments are covered in an appendix.
