Description

Double-joint bending control hard tube visual guide core

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a double-joint bending control hard tube visual guide core.

Background

Tracheal intubation is an important rescue technology commonly used in emergency treatment work, and is one of the most widely applied, effective and quick means in respiratory tract management. Especially for patients with cardiopulmonary resuscitation and acute critical illness accompanied with respiratory dysfunction, the emergency tracheal intubation is an important measure in the clinical rescue process. The tracheal intubation is used for placing a special tracheal catheter into the trachea through the glottis, is used for keeping the airway unobstructed, can provide good conditions for ventilation and oxygen supply, respiratory tract suction, erroneous suction prevention and the like, is one of basic skills which medical staff must be skillfully mastered, and plays a vital role in rescuing the life of a patient and reducing the death rate of the patient. Also, for some critically ill, general anesthesia patients, endotracheal intubation is a necessary means of maintaining respiratory function and medical personnel must place an endotracheal tube into a patient's trachea in a predetermined location in a short period of time to provide respiratory support. However, in clinic, patients with difficult airways often suffer from the problems that the traditional tracheal catheter implantation method adopting blind insertion can cause the tracheal intubation to be too long, the airways to be damaged and even the intubation to be failed, delay the treatment of the patients or miss the optimal rescue time, cause serious injury to the patients and even cause death of the patients, and bring medical risks to hospitals. Therefore, how to quickly and effectively complete the tracheal intubation becomes a key problem for patient treatment.

To solve the above problems, the technique of the visual guide core has been developed, and the method of using the technique is to sleeve the tracheal catheter on the visual guide core, then to perform the catheterization, and to guide the catheter to be inserted into the airway at a predetermined position by observing the imaging system of the visual guide core. The visual guide cores adopted clinically at present comprise a shapable visual guide core and a hard non-shapable visual guide core, wherein the shapable visual guide core comprises a handle with a display visual guide core and a single-handle (wireless transmission) visual guide core.

The hard non-shapable visual guide core is shaped in advance according to the physiological bending of the oropharynx, and has the advantages that the guide core is harder, the guide core cannot deform during intubation, and the guide core is not easy to damage due to the fact that repeated bending and shaping are not needed, and the guide core has the defects that the guide core cannot be shaped individually according to the physiological structure of a patient, and tissues such as oral mucosa, epiglottis, surrounding glottis and vocal cords are easily damaged due to the fact that the guide core is harder; the advantage and disadvantage of the shapable visual guide core is opposite to that of the hard non-shapable visual guide core. The visual guide core display of handle area display is generally fixed in the top or the side of handle through single joint structure, and flip angle has certain restriction, and its advantage is when carrying out the trachea cannula, and the display screen is unanimous with the catheterization direction, and the doctor can observe the display screen when putting the pipe, and redundant action is less, and the shortcoming is that the display screen can disturb doctor's operation, especially when the catheter pointed end gets into the oral cavity and arrives outside the sound door, and when catheter and guide core and patient's body become approximately 45 contained angles, the display screen can press close to doctor's chest, causes the display screen interface to be located outside doctor's field of vision because of flip angle is insufficient and causes unable observation and disturbance doctor's operation. The advantage of visual guide core of single handle is that the display breaks away from through wireless transmission image with the handle, uses lightly, and the shortcoming is that display screen and handle separation need additionally to prepare the fixed display of support, and the doctor need put the pipe simultaneously and twist the head and observe the display screen, influences and puts pipe efficiency.

How to solve the problems is a technical problem to be solved.
