Tracheostomy: Procedure and Tubes

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy Care II: Procedure

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...

Tracheostomy Suctioning II: Procedure

Tracheostomy Suctioning II: Procedure

Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Area of Science:

Robotics
Surgical Technology
Biomedical Engineering

Background:

Cochleostomy requires precise control to avoid damaging the endosteal membrane.
Existing autonomous surgical robots often rely on pre-operative data, limiting real-time adaptability.
Controlling surgical tools in flexible tissues presents challenges due to movement and interface variations.

Purpose of the Study:

To introduce a robotic micro-drilling technique for surgery.
To demonstrate real-time navigation using reactive drilling forces.
To achieve precise control of drill penetration in micro-surgical procedures.

Main Methods:

A robotic micro-drilling device was developed and deployed for cochleostomy.
The system navigates by analyzing transients in reactive drilling forces.
It discriminates cutting conditions, tissue state, and detects the medial surface before drill break-out.

Main Results:

The autonomous surgical robot successfully navigated in real-time without pre-operative data.
The technique enabled discrimination of tissue conditions and movements.
Controlled drill break-out or avoidance at the medial surface was achieved with high precision.

Conclusions:

This is the first autonomous surgical robot to use real-time force feedback for navigation.
The developed system offers unprecedented precision in controlling fine penetration during micro-surgery.
The technique addresses challenges in flexible tissue manipulation and patient movement during surgery.
