Tracheotomy cannula assembly and pen type integrated device thereof

Abstract

The invention discloses a tracheotomy cannula assembly, which comprises a puncture needle, a guide part and a cutter assembly. The puncture needle comprises a needle body and a needle tip, wherein anaccommodating cavity which is through from top to bottom is formed in the needle body; the guide piece is movably mounted in the accommodating cavity; the guide piece comprises a sleeve rod and a guide wire; the bottom end of the sleeve rod is fixedly connected with the top end of the guide wire; an accommodating cavity is formed in the sleeve rod from top to bottom; a notch is formed in the sidewall, close to the guide wire, of the accommodating cavity; the cutter assembly is installed in the containing cavity and comprises an installation shaft arranged in the containing cavity, a cutter isrotatably installed on the installation shaft and fixedly connected with a pull wire, the top end of the pull wire extends upwards to extend out of the containing cavity, and the cutter can be screwed out of the notch by pulling the pull wire. Tracheotomy is conducted from inside to outside, the incision wound surface is small, damage to subcutaneous tissue is small, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of tracheotomy, in particular to a tracheotomy assembly. Background technique [0002] Tracheostomy is an emergency operation to keep the airway open. By cutting the front wall of the neck and the trachea, a tracheostomy tube is inserted into the trachea of ​​the human body to ensure the patient's smooth breathing. For suffocation caused by airway obstruction caused by various reasons such as coma, laryngeal obstruction, and cerebral edema, tracheotomy and intubation is a common emergency operation with mature technology and significant effect. [0003] Currently, when performing a tracheotomy, the surgical steps are from the outside to the inside. Namely: First, cut the skin and subcutaneous tissue at least 3 cm along the anterior midline of the neck from the lower edge of the thyroid cartilage to the place close to the suprasternal fossa. The anterior wall of the tracheal ring forms the anterior wall fla...
