Instrument for lifting throat tissue and device used for complicated airways

Abstract

The invention provides an instrument for lifting throat tissue, and belongs to the technical field of medical apparatus and instruments. The instrument comprises a lifting handle and a lifting bent piece assembly which are detachably connected, the lifting bent piece assembly is provided with a bent piece, the thickness of the bent piece is 0.5-1 mm, and the width of the bent piece is 1-2 cm; theend of the bent piece is fixedly connected with the lifting handle, and the front end of the bent piece can enter from the oral cavity and reach the throat of a patient. The instrument for lifting thethroat tissue can expand the oropharyngeal space of the patient who is extremely restricted to opening the mouth, so that a broad and unobstructed ventilation or intubation path is formed in the oropharynx of the patient, and convenience is provided for a doctor to perform endotracheal intubation of a fiberoptic bronchoscope or other intubation auxiliary devices. The invention also provides a device used for complicated airways.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for lifting throat tissue and a difficult airway. Background technique [0002] A difficult airway is a clinical condition in which an anesthesiologist with more than five years of anesthesia experience has difficulty performing mask ventilation or intubation. [0003] "Patients will only die from failure of ventilation, not failure of intubation." In clinical practice, once difficulty in ventilation is encountered, the patient will easily enter a state of hypoxia and cause asphyxiation and death. The existing technical solutions and existing defects for difficult ventilation mainly contain the following: [0004] (1) Pressurized ventilation with nasopharyngeal airway placement: However, some patients still cannot improve ventilation due to obesity, soft palate or tongue hypertrophy, excessively long nasal passages, obstructed posterior nasal pore an...

AI Technical Summary

Problems solved by technology

[0004] (1) Pressurized ventilation with nasopharyngeal airway placement: However, some patients still cannot improve ventilation due to obesity, soft palate or tongue hypertrophy, excessively long nasal passages, obstructed posterior nasal pore and poor position of nasopharyngeal airway;

[0005] (2) Place supraglottic ventilation tools such as oropharyngeal airway, laryngeal mask, esophagus-trachea tube, laryngeal tube, etc. to pressurize oxygen: However, the placement of the above devices requires a mouth opening of about 2-3 cm, and for mouth opening less than 2 cm , 1cm, and 0.1cm patients cannot be inserted; and some patients with unlimited mouth opening may experience problems due to obesity, soft palate or tongue hypertrophy, too long or too short neck, implanted position Clinical conditions that still cannot improve ventilation, such as suboptimal;

[0006] (3) Try tracheal intubation again: Although this method has a slight success rate, it still has the defect that the laryngoscope cannot be placed in patients with limited mouth opening, and it is easy to force intubation for patients who do not meet the intubation conditions. Induce laryngospasm, bronchospasm and other life-threatening clinical situations

[0007] (4) Emergent cricothyropuncture tube insertion or tracheotomy: it is an invasive method, which is easy to damage the airway and cause serious sequelae, and still has the defects of puncture or incision failure and time-consuming

[0008] (5) The visual ventilation laryngoscope (patent number: 201220117131.4) granted by the State Intellectual Property Office of the People's Republic of China and the visual ventilation intubation laryngoscope (patent number: 201210417431.9) granted an invention patent have the following defects: First, The ventilation of both is realized through the ventilation handle, and the ventilation handle contains the ventilation lumen and the visible structure, which requires the handle to have a certain thickness. Or the difficult ventilation situation of patients with slightly limited mouth opening, and for patients with difficult ventilation with limited mouth opening (such as mouth opening less than 2cm, 1cm, 0.1cm) and tumors or foreign objects occupying space in the mouth, it cannot be placed because it cannot be placed. play a role; and both can only be ventilated through the mouth, not through the nasal cavity

Therefore, difficult fiberoptic bronchoscopic tracheal intubation lacks a device that can increase the exposure space of the pharyngeal cavity in patients with limited mouth opening
