KINCISE™ Surgical Automated System

Co-Linear Impaction

The KINCISE™ Surgical Automated System provides a controlled, co-linear impaction each time the trigger is depressed. The energy is delivered in the same location, direction, and vector. As a comparison, standard femoral preparation with a mallet requires multiple strikes on a broach handle. Each strike varies according to the direction of the mallet, the location on the strike plate the hit is made, and the force applied to the handle by the surgeon. These off-axis blows produce energy out-of-plane with the overall direction of movement. The KINCISE™ System allows that energy to be delivered in a colinear direction.

Controlled Energy Delivery

The KINCISE Surgical Automated System provides consistent and controlled energy delivery. This allows for a constant delivery of power to automate positioning, bone preparation and facilitate implant assembly. As a comparison, the energy from a typical mallet strike can vary during the various steps of a THA procedure. When there is less energy delivered with each impact, the concern of boney fracture may be alleviated within diverse types of bone quality.

Controlled Excursion

Typically in a THA procedure, using a mallet may have significant variations of excursion of the instrumentation and final implant based on a surgeon’s impact distance from the strike plate and the velocity imparted to the mallet. The patient’s bone quality and the sharpness of the cutting teeth are just a few other variables that lead to inconsistency of excursions. In some cases, mallet blows cause small excursions of the broach, stem or shell, while others cause large excursions. The KINCISE System has a controlled known total excursion distance with each impact to the instrumentation or implant, and the system cannot exceed the maximum by design.

Uni-directional

The KINCISE Surgical Automated System provides a controlled, co-linear impaction in the forward or reverse direction each time the trigger is depressed. This differs from The Woodpecker Pneumatic Broaching System from Integrated Medical Technologies whose motion sends the implement first forward, then backward repetitively in a reciprocating type motion. While the KINCISE System only hits uni-directional, mimicking the normal motions a surgeon makes in the operating room.

Delivers “free energy”

The KINCISE Surgical Automated System provides energy for bone preparation and implant placement. Based on Charles A. DeCook, M.D.’s discussion with other surgeon users, one of the most common complaints from orthopedic surgeons is the physical exhaustion that results from swinging the mallet hundreds of times per day. The KINCISE System delivers “free energy” to the surgeon via battery power. Much like the powered reamer that has become standard of care over the last thirty years, this now allows power to be applied to preparation and implantation, steps that require significant surgeon energy.

Conclusion

The KINCISE Surgical Automated System allows controlled delivery of energy during preparation and final implantation during total hip arthroplasty. Based on Charles A. DeCook, M.D.’s discussion with other surgeon users that have utilized the KINCISE System1, this technology is found to be intuitive and easy to use and allows these surgeons to quickly realize how much “free energy” they enjoy after discontinuing the use of a mallet.
