MedSpark -Acetabular Shell Impactor
Total Hip Arthroplasty (replacement) or THA surgery requires a wide range of specialized instruments for surgeons to successfully complete the surgical procedure. During a typical THA procedure, the acetabulum (hip socket) is resurfaced in preparation to receive the outer shell (typically titanium) of the acetabular component of the implant system. This outer shell must be positioned in all three rotational axes prior to being impacted into place by the surgeon. Many existing acetabular shell impactors are archaic devices which are both uncomfortable for the surgeon to hold and have durability issues during use.
MedSpark worked with our client, a medical device firm, to develop a new acetabular shell impactor that far exceeded their expectations and solved all the problems they had experienced with their previous devices. An ergonomically shaped, over-molded silicone grip replaced the old metal, waffle-iron shaped handle that was so uncomfortable and slippery for surgeons to hold and the shell holding mechanism was redesigned to be nearly impossible to break under normal use - a problem that had plagued their previous shell impactor designs.
