Summary
Mixed-reality navigation using 3D holographic models aids surgeons in transvaginal procedures for pelvic floor disorders. This technology enhances anatomical understanding and surgical confidence, proving feasible and useful for complex cases.
Area of Science:
- Medical technology
- Surgical innovation
- 3D visualization
Background:
- Transvaginal surgeries for stress urinary incontinence and pelvic organ prolapse present anatomical challenges.
- Enhanced visualization can improve surgical outcomes and reduce complications.
Purpose of the Study:
- To assess the feasibility and perceived utility of mixed-reality (MR) navigation.
- To utilize patient-specific 3D holographic models from CT scans for intraoperative guidance.
Main Methods:
- Computed tomography (CT) data were transformed into 3D holographic models using the HoloEyes MD system.
- HoloLens 2 projected holograms for intraoperative guidance in 24 transvaginal surgeries.
- Surgical tools were integrated as spatial reference markers.
Main Results:
- MR navigation improved surgeons' spatial understanding of pelvic anatomy and workflow.
- Enhanced anatomical comprehension and usefulness were reported during planning and surgery.
- System familiarity increased with repeated use.
Conclusions:
- MR-assisted navigation is feasible for transvaginal procedures.
- The technology supports surgeons' spatial understanding and confidence.
- It shows potential as an educational and intraoperative tool in urology and gynecology.

01:11Anatomical Positions
19.9K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:20Anatomical Terminology
27.1K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

00:51Anatomical Movements
15.7K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

01:19Muscles that Move the Head
5.9K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

01:11Cerebrum: Anatomical Overview II
4.9K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

5.4K
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...
