Summary
Laparoscopic graspers can damage tissue. Increasing the radius of curvature on grasper edges or teeth can reduce this damage, aiding in the design of safer surgical instruments.
Area of Science:
- Biomedical Engineering
- Surgical Instrumentation
- Tissue Mechanics
Context:
- Laparoscopic surgery relies on graspers, which apply significant force during clamping.
- High clamping forces can lead to iatrogenic tissue damage and surgical complications.
- Current grasper designs may not adequately mitigate tissue injury during procedures.
Purpose:
- To evaluate the impact of grasper design parameters on tissue damage.
- To investigate the relationship between grasper curvature, teeth, and stress concentration.
- To provide data for the development of safer, non-invasive laparoscopic graspers.
Summary:
- Experimental and finite element analyses were conducted using rabbit intestine models to assess tissue damage from graspers.
- Tissue damage was most severe at the jaw edges due to stress concentration.
- Increasing the radius of curvature of grasper edges and teeth significantly reduced tissue damage.
Impact:
- Findings offer crucial data for selecting and designing laparoscopic graspers with reduced tissue injury potential.
- This research contributes to improving patient safety in minimally invasive surgery.
- The study promotes the development of advanced surgical tools for more effective and less damaging procedures.

The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...

The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

The first order operators using the del operator include the gradient, divergence and curl. Certain combinations of first order operators on a scalar or vector function yield second order expressions. Second-order expressions play a very important role in mathematics and physics. Some second order expressions include the divergence and curl of a gradient function, the divergence and curl of a curl function, and the gradient of a divergence function.
