Summary
A new robotic probe navigates delicate spaces in cardiac surgery, enabling precise interventions within the pericardial cavity. This highly articulated robotic probe (HARP) offers enhanced maneuverability for surgeons.
Area of Science:
- Robotics and Mechanical Engineering
- Surgical Technology
- Biomedical Devices
Background:
- Minimally invasive cardiac surgery requires advanced tools for precise tissue manipulation.
- Accessing deep intrapericardial locations can be challenging with conventional instruments.
- Existing robotic systems may lack the necessary articulation for complex cardiac procedures.
Purpose of the Study:
- To develop and validate a novel highly articulated robotic probe (HARP) for cardiac surgery.
- To enable surgeons to reach and treat remote intrapericardial locations with high precision.
- To demonstrate the HARP's maneuverability and ability to navigate confined anatomical spaces without causing collateral damage.
Main Methods:
- Development of a highly articulated robotic probe (HARP) utilizing conventional actuation methods.
- Design of the HARP for entry into the pericardial cavity via a subxiphoid port.
- Proof-of-concept clinical experiments for preliminary validation.
Main Results:
- The HARP demonstrated the ability to thread through tightly packed volumes without disturbing surrounding tissues and organs.
- The device achieved effective access to remote intrapericardial locations on the epicardium.
- Preliminary validation through proof-of-concept clinical experiments confirmed the system's feasibility.
Conclusions:
- The novel highly articulated robotic probe (HARP) is a promising tool for minimally invasive cardiac surgery.
- The HARP offers significant maneuverability for precise therapeutic interventions within the pericardial cavity.
- Further clinical validation is warranted to establish the full potential of this robotic system in cardiac procedures.

Articulations of the Vertebral Column
3.2K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Labeling DNA Probes
9.4K
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Types of Errors: Detection and Minimization
11.4K
Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.

Mechanical Ventilation II: Invasive Ventilation
777
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Threats to Biodiversity
27.1K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Halogens
23.6K
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid. Astatine is a highly unstable radioactive element, so currently, most of its properties are unknown due to its short half-life. Tennessine is a synthetic element also predicted to be in this group.
