3D Guidance® Training Needle
Needle-tip tracking and deflection visualization capabilities for OEM medical simulators and trainers.
Enhance Procedure Skills Development of Future Clinicians
The 3D Guidance Training Needle is an 18-gauge, 110 mm length reusable titanium needle with a micro electromagnetic sensor embedded at its tip, which enables needle-tip tracking and deflection visualization from inside the phantom. These capabilities support the training of needle targeting and trajectory planning during simulated renal biopsies, TAP blocks, cordocentesis, spinal epidurals, and other procedures.
Used in conjunction with the 3D Guidance electromagnetic tracking solution, the 3D Guidance Training Needle supports realistic and effective OEM needle-guidance training. Its integration and use in simulator or trainer workflows are similar in principle to OEM clinical applications, where the 3D Guidance solution can provide 6DOF tool tracking without line-of-sight constraints.

3D Guidance Training Needle Components
2. CannulaThe 18-gauge surgical steel cannula is
110 mm long and features a Quincke tip. It can be used for extensive punctures before replacing.
The shaft (with encased sensor) is inserted into the cannula and secured with a Luer lock. The assembled needle requires no calibration.
The 3D Guidance Training Needle supports a training experience that realistically simulates clinical image-guided needle procedures by tracking the tip’s actual position, as opposed to having to calculate the tip offset. Needle-tip tracking supports accurate targeting and trajectory planning during simulated procedures by continually visualizing the needle’s depth and trajectory.
- Tip tracking achieved via an embedded micro sensor – the same used in OEM clinical procedures.
- Enables depth and trajectory to be continually visualized, even if the needle flexes.
The 3D Guidance Training Needle enables the needle’s angle of deflection to be visualized from inside the phantom. Deflection visualization shows the trainee if the needle has deviated from its insertion path and is now off-target, and to course-correct accordingly. It can also provide visual cues for determining the force required during puncture.
- Allows for a visual representation of the degree of needle flexion during puncture.
- Deflection visualization is calculated using two sensors: one at the needle’s tip and another at the proximal end.
The 3D Guidance Training Needle consists of a Model 55 Sensor embedded inside a titanium shaft. This shaft is inserted into a replaceable surgical steel cannula and secured by a Luer lock. Trainees can reuse the same needle repeatedly during a training session, eliminating high cannula replacement costs. The cannula is open, supporting use for an integrated guidewire or syringe as required by the training scenario.
- Tested to perform up to 400 needle punctures on soft phantom materials.
- Designed with resilient materials that allow for moderate needle flexion.
The 3D Guidance Training Needle features high measurement accuracy and low system latency (via the 3D Guidance solution) that are consistent with the performance of image-guided surgery systems, supporting a realistic training experience. This level of accuracy is required when targeting a small treatment area, where each precise needle movement must be visualized in the training interface.
- Following cannula replacement, tracking performance is sustained.
- High tracking accuracy and reliability foster trainee confidence – the needle performs the same every time. Consistent training tools promote consistent task development.
The 3D Guidance Training Needle—like the entire 3D Guidance tracking solution—is designed for ease and speed of integration into OEM medical simulators and trainers. The needle is a standard size for many clinical procedures, offering immediate use in equivalent training applications. The needle requires minimal configuration before use.
- Factory-calibrated – no user calibration or re-calibration necessary.
- Custom-sized needles are available.
