Contact Angle01:13

Contact Angle

19.7K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Open Angle Glaucoma: Treatment

997
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle of Twist: Problem Solving01:13

Angle of Twist: Problem Solving

794
An electric motor applies a torque of 700 N·m to an aluminum shaft, triggering a stable rotation. Two pulleys, B and C, are subjected to torques of 300 N·m and 400 N·m, respectively. The modulus of rigidity is provided as 25 GPa. With the knowledge of the length and diameter of each segment, the twist angle between the two pulleys can be computed. First, a section cut is made between pulleys B and C, and the cut cross-section is analyzed using a free-body diagram. Given that the torque...

Angle Closure Glaucoma: Treatment

1.3K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Design Example: Traverse Angle Computations

341
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Angle of Twist - Elastic Range01:13

Angle of Twist - Elastic Range

808
Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...

Summary
This summary is machine-generated.

A new Tackdriver training model effectively simulates microinvasive glaucoma surgeries (MIGS) for resident training. This cost-effective method allows high-volume practice of procedures like iStent insertion and gonioscopy-assisted transluminal trabeculotomy (GATT).

Area of Science:

  • Ophthalmology
  • Surgical Education
  • Medical Technology Evaluation

Background:

  • Microinvasive glaucoma surgeries (MIGS) require specialized training.
  • Existing training models may have limitations in cost or accessibility.

Purpose of the Study:

  • To assess the efficacy of the Tackdriver training model for new-generation MIGS procedures.
  • To evaluate the model's suitability for resident training in Canada.

Main Methods:

  • Human cadaver corneoscleral rims were utilized and inverted.
  • The Tackdriver model facilitated practice of microbypass stent insertion and gonioscopy-assisted transluminal trabeculotomy (GATT).
  • The model was assessed for preparation ease, simulation accuracy, and procedural versatility.

Main Results:

  • High-volume training for microbypass stent insertion (first and second generation) was achieved.
  • The GATT procedure was successfully simulated in various segmental treatments (90-360 degrees).
  • The model demonstrated good fidelity for bimanual angle surgery simulation.

Conclusions:

  • The Tackdriver model provides a simple, efficient, and cost-effective platform for high-volume MIGS training.
  • It enables practice of MIGS techniques, including stent insertion/removal and GATT, independent of corneal clarity.
  • The model is adaptable for other angle-based training procedures.
