Puncture device, trachea cutting device and trachea cutting method

Abstract

The invention discloses a puncture device, a trachea cutting device and a trachea cutting method. The trachea cutting device comprises a marking device for marking the lengths of an incision line and an incision, a tool for cutting the skin along the incision line, a puncture device for vertically penetrating into a trachea in the incision, a verifying device for verifying whether the puncture device penetrates into the trachea or not, a guide wire for playing a guide role, a skin expander for expanding the skin of a puncture point, a long support tube for guiding a subcutaneous tunnel expander and a trachea device to enter the trachea, a tunnel expander for creating and expanding a channel clearance between the skin surface to the trachea to form a subcutaneous tunnel, and a trachea device communicating with the trachea and capable of absorbing a liquid from the trachea. The trachea cutting method implemented by adopting the trachea cutting device has the characteristics that the size of the incision is accurately estimated, the judgment accuracy of puncture is improved, an over-large puncture depth is avoided, and the trachea cutting security can be effectively improved.

Description

technical field [0001] The invention relates to a trocar, a tracheotomy device and a tracheotomy method. Background technique [0002] Tracheotomy is one of the common operations in emergency, ICU, and otolaryngology-head and neck departments. Tracheostomies include: conventional tracheostomy, cricothyrotomy, percutaneous tracheostomy and minimally invasive tracheostomy. It is mainly applicable to: 1. Severe laryngeal obstruction caused by pharyngeal inflammation, tumor, trauma, foreign body, etc.; 2. Retention of secretions in the lower respiratory tract caused by various reasons. In order to suck sputum and keep the airway unobstructed, tracheotomy may be considered. Open, such as severe craniocerebral injury, respiratory burn, severe chest trauma, etc.; 3. Preventive tracheotomy; 4. Tracheal foreign body removal; Difficulty breathing immediately. [0003] The main complications after tracheotomy are bleeding, respiratory arrest, pneumothorax, subcutaneous emphysema, an...

Problems solved by technology

[0004] The common problems in tracheotomy are: 1. During the operation, the front part of the puncture needle is often blocked by tissue, and it is mistakenly thought that it is not in the trachea, resulting in the failure of tracheotomy, or the puncture is too far, causing damage to the posterior wall of the trachea and causing tracheoesophageal Fistula; 2. Unable to estimate the length of the in...
