HURWA KHRobot-6800 Full Orthopedic Surgical Robot

The HURWA KHRobot-6800 represents Hurwa’s second-generation orthopedic surgical platform, expanding beyond knee replacement to encompass hip arthroplasty and spine surgery. As of June 2024, this system became the first domestic orthopedic surgical robot in China to receive NMPA approval for knee, hip, and spine surgical indications on a single integrated platform.

Product Overview

Building on the clinical success of the KRobot-5800, the KHRobot-6800 addresses orthopedic departments’ needs for a versatile robotic system capable of supporting multiple procedure types. Rather than requiring separate robots for different joint or spine surgeries, the platform consolidates these capabilities into one system with expandable software modules.

The initial NMPA registration in May 2023 covered total knee arthroplasty (TKA), total hip arthroplasty (THA), and femoral/tibial osteotomy procedures. In June 2024, Hurwa received approval to extend indications to spine surgery, marking a significant expansion of the platform’s clinical utility.

Key Features

Multi-Indication Platform: Single hardware system supports knee replacement, hip replacement, osteotomy, and spinal procedures through software configuration changes, reducing capital equipment costs for orthopedic departments.

Enhanced Navigation: Upgraded optical tracking and registration algorithms improve accuracy across different anatomical regions and surgical approaches.

Hip Module: Purpose-built planning and execution tools for acetabular cup positioning and femoral stem alignment in total hip arthroplasty.

Spine Module: Pedicle screw placement guidance and vertebral body navigation for spinal fusion and fixation procedures.

Open Implant Compatibility: Maintains the open-platform philosophy of the first-generation system, supporting prostheses and fixation hardware from multiple manufacturers.

Technical Specifications

For orthopedics, Hurwa’s KHRobot-6800 provides NMPA-approved TKA, THA, osteotomy, and spine procedures on a single KUKA-based arm with under 0.5 mm bone resection accuracy.

Clinical Applications

Joint Replacement

For total knee and hip arthroplasty, the KHRobot-6800 provides preoperative CT-based planning, intraoperative registration, and real-time navigation during bone preparation. The system generates patient-specific surgical plans accounting for individual anatomy, implant selection, and desired alignment parameters.

Osteotomy Procedures

The platform supports high tibial osteotomy (HTO) and distal femoral osteotomy (DFO) for patients requiring corrective procedures rather than full joint replacement. Precise angular correction is planned preoperatively and executed with robotic guidance.

Spine Surgery

The spine module enables guided pedicle screw placement and vertebral navigation. This expansion positions the system for broader orthopedic department utilization beyond joint specialists.

Regulatory Status

Hurwa plans to pursue additional indication expansions in 2025 including unicompartmental knee arthroplasty (UKA), trauma surgery, and sports injury repair applications.

Frequently Asked Questions

What is the difference between KRobot-5800 and KHRobot-6800?

The KRobot-5800 is Hurwa’s first-generation system approved only for knee replacement (TKA). The KHRobot-6800 is a second-generation platform that adds hip replacement (THA), osteotomy procedures, and spine surgery capabilities. For departments requiring multi-joint or spine robotics, the KHRobot-6800 offers consolidated functionality on a single platform.

Can KHRobot-6800 perform unicompartmental knee replacement?

As of the current NMPA registration, the KHRobot-6800 is approved for total knee arthroplasty (TKA) rather than unicompartmental (partial) knee replacement. Hurwa has indicated plans to pursue UKA indication expansion in 2025.

What spine procedures does the system support?

The spine surgery module, approved in June 2024, supports pedicle screw placement and vertebral navigation for spinal fusion and fixation procedures. The system provides trajectory planning and real-time guidance during screw insertion to improve accuracy and reduce fluoroscopy exposure.

Is international regulatory approval planned?

Hurwa has not publicly announced CE Mark or FDA 510(k) filing timelines for the KHRobot-6800. The company’s current focus appears concentrated on the Chinese domestic market and potential Beijing Stock Exchange listing.
