TH-P Portable Puncture Surgery Navigation System

The TH-P represents TrueHealth’s second-generation puncture surgical robot, featuring a miniaturized and lightweight design optimized for deployment in space-constrained clinical environments. Approved by NMPA in December 2024, this portable system maintains the core navigation capabilities of its predecessor while offering enhanced mobility and operational flexibility.

Product Overview

Building on clinical experience from the TH-S1 platform, the TH-P addresses practical deployment challenges encountered in diverse hospital settings. Many CT suites and interventional radiology rooms have limited floor space, making full-sized robotic systems difficult to accommodate. The TH-P’s compact form factor enables adoption in facilities where space constraints previously precluded robotic-assisted procedures.

The system retains the integrated navigation, respiratory tracking, and robotic positioning capabilities that established the TH-S1’s clinical effectiveness, packaged in a portable configuration suitable for mobile deployment between procedure rooms.

Key Features

Miniaturized Robotic Arm: TrueHealth’s proprietary lightweight robotic arm design significantly reduces the system footprint while maintaining the precision and stability required for sub-millimeter needle positioning. The compact arm enables operation in confined spaces adjacent to CT scanners.

Mobile Platform Architecture: Unlike fixed robotic installations, the TH-P can be repositioned between procedure rooms, maximizing utilization across multiple clinical services within a facility.

Integrated Navigation Suite: The system incorporates dynamic registration, optical tracking, robotic arm control, and respiratory motion compensation in a compact package optimized for rapid setup and deployment.

Collaborative Robot Design: As TrueHealth’s first mobile collaborative robot platform, the TH-P is designed for safe operation in close proximity to clinical staff, with integrated safety monitoring throughout the procedure.

Technical Specifications

TrueHealth’s TH-P is a portable collaborative robot with sub-millimeter optical tracking accuracy, NMPA-approved in December 2024 for CT-guided soft tissue puncture procedures.

Clinical Applications

The TH-P supports the same range of thoracoabdominal percutaneous interventions as its larger predecessor:

Diagnostic Applications: CT-guided biopsy of lung nodules, liver lesions, kidney masses, and other soft tissue targets for pathological analysis.

Therapeutic Support: Needle placement for ablation procedures, preoperative tumor localization, and radioactive seed implantation guidance.

Target Population: Adult patients requiring percutaneous interventions of pulmonary and abdominal solid organs.

Regulatory Status

The TH-P approval in December 2024 marked TrueHealth’s second Class III medical device certification within that calendar year, following the microwave ablation system approval in September. This brought the company’s total Class III registrations to five products.

Design Philosophy

The TH-P development reflects lessons learned from widespread TH-S1 deployment across Chinese hospitals. While the original system demonstrated strong clinical outcomes, feedback indicated that some facilities could not accommodate the space requirements of a full-sized robotic platform.

Rather than simply scaling down the existing design, TrueHealth undertook ground-up development of a medical-grade miniaturized robotic arm. This proprietary component enables the compact form factor while preserving the positioning accuracy and stability that underpin clinical effectiveness.

Frequently Asked Questions

How does the TH-P differ from the TH-S1?

The TH-P features a significantly smaller footprint through its miniaturized robotic arm design, enabling deployment in space-constrained CT suites. The portable platform allows the system to be shared between multiple procedure rooms. Core navigation and tracking capabilities remain comparable to the TH-S1.

What clinical environments benefit most from the portable design?

Hospitals with limited interventional radiology suite space, facilities seeking to add robotic capability without dedicated room allocation, and institutions wanting to share a single system across multiple departments may find the portable configuration advantageous.

Does the compact size compromise precision?

According to TrueHealth, the miniaturized design maintains sub-millimeter positioning accuracy. The engineering challenge was achieving size reduction without sacrificing the stability and precision required for soft tissue interventions.
