Description
Technical Field
The utility model relates to the technical field of cricothyroid membrane incision, in particular to a cricothyroid membrane puncture spreader.
Background
When a patient suffers from the critical condition of upper respiratory obstruction, if the patient cannot be subjected to nasal or oral intubation and is subjected to laryngeal mask obstruction, the patient can die in a few minutes due to asphyxia, so that the rapid establishment of the airway ventilation in the emergency operation is the most important method for rescuing the patient suffering from the upper respiratory obstruction. At present, three main operations for establishing an emergency operation airway at home and abroad are as follows: namely, cricothyroid membrane puncture, cricothyroid membrane incision, tracheotomy. The advantages and disadvantages of these techniques are different.
First, the cricothyroid membrane puncture technique has the advantages that: one person can complete the operation, the application equipment is minimum, the operation is simplest, the time is shortest, and various large puncture needles, needle tubes or special puncture instruments are commonly used. The disadvantages are: the needle, needle tube or special puncture outfit which is inserted into the cricothyroid membrane in an emergency way has the defects of serious insufficient inspiration amount and difficult expiration caused by too small caliber. In general, the cricothyroid puncture is often only used as a first-aid time for several minutes, and high-pressure pure oxygen auxiliary treatment must be intermittently given at once to improve the oxygen deficiency state, but the success rate of the rescue is still low, and it is necessary to prepare for the tracheotomy as soon as possible. Therefore, the actual clinical significance of cricothyroid centesis is less in most emergency situations.
Second, the advantages of tracheotomy are: the patient can breathe with a tube permanently after the operation is successful, and the postoperative throat stenosis complication is extremely low; the disadvantages are evident: because the tracheotomy is deep, the 2 nd-4 th tracheal rings are often cut, the surfaces of the 2 nd-4 th tracheal rings are covered with thyroid glands and two layers of anterior cervical banded muscles, obvious anatomical marks are vague, the operation is very difficult to complete, at least two persons or more than two persons are required to cooperate to operate, the light source, the tracheotomy bag and other instruments and equipment are required, the operation time is far longer than that of the cricotomy and the puncture, and the complication occurrence rate of bleeding, subcutaneous pneumothorax, esophageal injury and the like is higher, so that the tracheotomy is not preferred in the pre-hospital and intra-hospital emergency.
Third, the advantages of a cycloarterectomy: the operation position is higher and superficial, the anatomical sign is obvious, the positioning is easy, the operation can be completed only by about 30 seconds to 1 minute under the condition that a professional doctor is more skilled, the 4-5 tracheal cannula or the tracheal catheter can be inserted, the tracheal catheter has a wider pipe diameter, the basic breathing requirement of an adult can be met, and the airway can be closed to prevent aspiration. The disadvantages are: the incision of the cricothyroid membrane is relatively small, and the tracheotomy needs to be changed when the caliber of the cannula is too large or the time for taking the cannula is long, so that the risk of subglottic laryngeal stenosis can be caused. Therefore, the cricotomyelitis is the most commonly used emergency operation airway technique abroad, and becomes the most effective first-aid method for rapidly opening the airway. However, the operation is still greatly affected by the operation proficiency of operators, the operation experience, the operation instrument equipment, the application after training and other factors, the operation time is relatively long, and the success rate of emergency operation is still limited to a certain extent.
Along with the continuous improvement of the requirements of people on health consciousness and rescue success rate, new rescue surgery technology of emergency laryngeal upper respiratory tract obstruction is continuously popularized and promoted by various scholars, new equipment is updated, the special emergency technology skill is continuously mature and perfect, but once emergency upper respiratory tract obstruction patients need emergency treatment in hospital and clinical various disease areas or anesthesia department induced anesthesia intubation fails, the emergency cricothyroid membrane incision is still the most effective and optimal operation mode at home and abroad at present when emergency operation airway ventilation relief dyspnea is still required to be established to save life when internal medicine such as nasal intubation or laryngeal mask obstruction fails to be induced.
The current clinically used instrument for the ascending emergency cricotomy is mainly a tracheotomy instrument, and the instrument has the following defects: firstly, the emergency operation can be performed only by the doctors in the otorhinolaryngology department or the head and neck department during the operation, and the operation time is long, and the influence of the technical proficiency and experience of the patients, the emergency operation sites and the on-duty surgeons is great. Therefore, the rescue success rate is still difficult to improve; secondly, the cricotomy is implemented under the most urgent condition, and possibly has a plurality of conditions such as hypoxia and agitation of sick and wounded, insufficient preparation of on-site articles and the like, and in such conditions, rapid positioning of cricothyroid shape must be realized, bleeding is reasonably treated, airway ventilation is smoothly cut, hypoxia time and unnecessary side injury are reduced, but the current instrument cannot realize the requirements.
Therefore, it is clinically necessary to develop a cricothyroid membrane puncture spreader, which can not only rapidly complete cricothyroid membrane puncture, but also directly cut and enlarge a puncture opening, avoid side injury, and rapidly and smoothly insert an endotracheal tube or an endotracheal tube to complete ventilation of an emergency operation airway, thereby improving rescue success rate.
