Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

  • Minimally invasive surgery (MIS) training requires effective methods to reduce the learning curve.

Purpose of the Study:

  • To develop a cost-effective haptic-based simulator for surgical residents.
  • To improve the acquisition of core surgical skills through pre-training.
  • To enhance the diagnostic capabilities of internal organ disease detection via palpation using a novel simulator.

Main Methods:

  • Integration of a real-time surface stiffness adjustment algorithm.
  • Development and implementation of a novel 'force maps' paradigm.
  • Utilizing a visuo-haptic simulator module for training.

Main Results:

  • The simulator provides realistic tactile feedback for tissue property assessment.
  • The force map paradigm offers a new approach to palpation-based diagnostics.
  • The system is designed to reduce skill acquisition time and risks in surgical training.

Conclusions:

  • The developed visuo-haptic simulator effectively trains internal organ disease diagnostics through palpation.
  • The integration of advanced haptic feedback and force maps can significantly improve surgical training outcomes.
  • Novel simulators are essential for efficient and safe skill development in minimally invasive surgery.
