Technical Field
The invention relates to the field of medical equipment, in particular to a combined autogenous cutting catheter.
Background
Tracheotomy catheters are used for tracheotomy patients and are classified into metal tubes and plastic tubes with cuffs.
The current clinical laryngeal cancer patient operation flow: the local anesthesia tracheotomy is placed through the tracheostoma into a conventional stiffening tube with a cuff. Change the conduit after the operation according to the operation condition: a plastic tube with a cuff, or a metal tube without a cuff.
The exterior of the current tracheostomy tube is close to the surgical operation site, affecting the surgical operation. With the selection of conventional stiffening tubes, intraoperative surgical pulling can result in rupture of the tracheal catheter cuff. The catheter needs to be replaced after the operation, and the replacement of the catheter needs to wait for the recovery of the respiratory consciousness of the patient, so that the operation time of the patient is prolonged, pain and dysphoria of the patient are caused, and the bleeding and infection risks are increased; even misplacement into the tracheal sinus can occur, increasing the risk of death.
In addition, most of the tracheostomy tube is likely to be attached by sputum to form sputum scab at any time in the operation, so that the tracheostomy tube is blocked, the breathing machine is difficult to send air, the secretion of the respiratory tract is difficult to clear, and the airway blocking endangering the life of a patient can occur in serious cases. In order to ensure the smooth airway, the tracheostomy tube needs to be replaced in time, however, a great risk exists when the tracheostomy tube is replaced, particularly, in 48 hours after the tracheotomy, the tracheotomy sinus tract is not formed yet, once the tracheostomy tube is pulled out, the tracheostomy tube is difficult to reinsert, and respiratory obstruction and serious hypoxia of a patient are caused, and even death is caused. The traditional autogenous cutting catheter also needs to be replaced regularly in the wound healing process of a patient, and the traditional autogenous cutting catheter also needs to be replaced along with the wound healing process due to different sizes of the wound, so that secondary injury and infection are easily caused to the wound of the patient.
Many patients with tracheotomy can suffer from systemic edema, the general tracheostomy tube fixing ropes are not elastic, the ropes are thin, and when the patients with the edema are in coma, the common cotton ropes are used for fixing the tracheal cannula, so that pressure sores of neck skin can easily occur.
