The summary describes a robotic surgical system for hip arthroplasty that uses preoperative planning software and a robotic arm for precise implementation. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies. The system appears to be based on pre-programmed plans and image-guided navigation rather than adaptive or learning algorithms.
Yes.
This device is used directly in a surgical procedure to prepare anatomical sites for total hip arthroplasty, indicating it has a direct therapeutic effect by assisting in the physical modification of the patient's body for treatment.
No
The device is described as a "preoperative planner and implementation tool" and a "robotic surgical tool" used to precisely implement a presurgical software plan and assist surgeons during intraoperative procedures. While it uses diagnostic images for planning, its primary function is surgical planning and execution (broaching, reaming, impacting techniques), not diagnosis.
No
The device description explicitly states the system consists of both software (TPLAN™ Preoperative Planning Workstation) and hardware components (TCAT™, a robotic system composed of an electromechanical arm, arm base including control electronics and computer, display monitor, and miscellaneous accessories).
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic or monitoring purposes.
- Device Function: The TSolution One™ w/ACG+ Surgical System is a surgical planning and robotic implementation tool used during surgical procedures. It uses diagnostic images (CT scans) for planning and guidance, but it does not analyze biological specimens in vitro.
- Intended Use: The intended use clearly states its purpose is for surgical planning and providing orientation/reference information during intraoperative procedures, and for precisely implementing a presurgical plan. This is a surgical assistance device, not a diagnostic test performed on a sample outside the body.
Therefore, the TSolution One™ w/ACG+ Surgical System falls under the category of a surgical device or system, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The TSolution One™ w/ACG+ Surgical System is intended for use as a device that uses diagnostic images of the patient acquired specifically to assist the physicial planning and to provide orientation and reference information during intraoperative procedures. The robotic surgical tool, under the surgeon, precisely implements the presurgical software plan.
The preoperative planning software and robotic surgical tool is used as an alternative to manual planning and broaching/ reaming/impacting techniques for femoral canal and acetabular cup preparation in primary cementless total hip arthroplasty (THA) using a posterior approach.
The TSolution One w/ACG+ Surgical System is indicated for orthopedic procedures in which the broaching, reaming and impacting techniques used in primary cementless total hip arthroplasty (THA) using a posterior approach may be considered to be safe and effective and where references to rigid anatomical structures may be made. The TSolution One™ w/ACG+ Surgical System is also intended to assist the surgeon in determining reference alignment axes in relation to anatomical and instrumentation structures during stereotactic orthopedic surgical procedures. The TSolution One™ w/ACG+ Surgical System facilitates accurate positioning of THA implants, relative to these alignment axes.

Device Description
The TSolution One™ w/ACG+ Surgical System is a three-dimensional, graphical, preoperative planner and implementation tool for treatment of patients who require a total hip arthroplasty (THA) procedure. This device is intended as an alternative to manual template planning, broaching, reaming and impacting techniques for the preparation of femoral canal and acetabular cup for patients requiring a primary THA procedure. The system consists of the TPLAN™ Preoperative Planning Workstation and TCAT™, a robotic system composed of an electromechanical arm, arm base including control electronics and computer, display monitor, and miscellaneous accessories such as cutters, drapes, irrigation sets, probes, and markers. TPLAN™ and TCAT™ when used according to the instructions for use, make precision femoral canal and acetabular cup preparation possible before and during THA surgical procedures ..
