Intended Use

HIP7 is intended to be an intraoperative image-guided localization system to enable minimally invasive surgery. It links a freehand probe, tracked by a passive marker sensor system, to virtual computer image space either on a patient's preoperative image data being processed by Brainlab IGS platforms, or on an individual 3D-model of the patient's bone, which is generated through acquiring multiple landmarks on the bone surface. The system is indicated for any medical condition in which the use of stereotactic surgery may be considered to be safe and effective, and where a reference to a rigid anatomical structure, such as a long bone or vertebra, can be identified relative to a CT, X-Ray, or MR-based model of the anatomy. The system aids the surgeon to accurately navigate a hip endoprosthesis to the preoperatively or intraoperatively planned position. Example orthopedic surgical procedures for the Computer Assisted Total Hip Replacement – HIP7 use case include but are not limited to: - Total Joint Replacement - Minimally invasive orthopedic surgery

Device Story

Intraoperative image-guided localization system; links freehand probe tracked by passive marker sensor system to virtual computer image space. Inputs: preoperative image data or 3D-model of patient bone generated via landmark acquisition. Operation: system registers landmarks to navigate surgical tools (e.g., cup inserter) to planned positions; measures leg length and offset changes. Used in OR by surgeons for orthopedic procedures (e.g., total hip replacement). Output: 3D reconstruction of anatomical axes/planes, implant orientation, and leg length/offset parameters displayed on navigation station. Benefits: aids accurate implant navigation and alignment; enables minimally invasive approach.

Clinical Evidence

Bench testing only. Verification and validation performed according to Brainlab's design and development procedures. No clinical data presented.

Technological Characteristics

Stereotaxic instrument; infrared tracking with passive marker spheres. Compatible with various Brainlab navigation platforms (Kick, Curve, BUZZ). Software-based navigation of surgical tools. Connectivity via navigation station hardware. Sterilization: not specified (standard surgical instrument protocols apply).

Indications for Use

Indicated for patients requiring stereotactic surgery where a rigid anatomical structure (long bone or vertebra) can be referenced to CT, X-Ray, or MR-based models. Used for total joint replacement and minimally invasive orthopedic surgery.

Regulatory Classification

Identification

The HIP7 system is intended to enable navigation in orthopedic hip replacement Device Description: surgery. It links a surgical instrument, tracked by flexible passive markers to virtual computer image space on an individual three-dimensional model of the patient's bone, which is generated through acquiring multiple landmarks on the bone surface or soft tissue. The HIP7 system uses the registered landmarks to navigate the necessary surgical tool, i.e., cup inserter, to the desired orientation. Additionally, it enables to intra-operatively measure the changes in leg length and offset.

The HIP7 system provides a three-dimensional reconstruction of the relevant anatomical axes and planes of the femur and pelvis to aid the alignment of the implants and to determine leg length and offset parameters. Based on the selected procedure, the HIP7 system loads implant and instrument data that has been provided by the implant manufacturer. The implant is selected according to the available license and is then shown in the software in relation to the determined anatomical structures. A preoperative x-ray may optionally me loaded. The HIP7 system does not require CT-based imaging.

### Technological Characteristics and Substantial Equivalence

The HIP7 system has been verified and validated according to Brainlab's procedures for product design and development.

### Summary

The changes described above do not alter intended use or the fundamental scientific technology of the device because they do not change the operating principle. The changes to the HIP7 do not present any new issues of safety and effectiveness when compared to the predicate device.

The HIP7 system described in this submission is, in our opinion, substantially equivalent to the predicate.
