Description
Technical field
The utility model is related to medicine equipment, in particular to a kind of adjustable Airway dilation sacculus of airway diameter.
Background technology
Trachea-bronchial epithelial cell narrow reason is more common in air flue lesion (such as：Benign or malignant tumour, inflammation in trachea-bronchial epithelial cell
Property granuloma and air flue in foreign matter etc.), narrow distal end can be caused to ventilate limited, severe patient can cause significantly to have difficulty in breathing, very
To that may suffocate, urgent respiratory tract PCI is now usually needed.Air flue is needed to use to expand through bronchoscope balloon dilatation
Sacculus is expanded to narrow positions, expands narrow positions effective ventilation diameter, it is considered to be it is a kind of it is easy, quick, effective,
The method of the reconstruction air flue caliber of safety.
Conventional Airway dilation sacculus, external diameter is less than 2.8mm when non-aerating, can treat duct by soft airway wall and enter
Go out, more convenient, it can also be used to narrow positions is expanded under Rigid bronchoscope, the narrow positions that is particularly suitable for use in is narrow and small to be suffered from
Person.But because middle without ventilation tube chamber, the sacculus of gas injection (or water) can block the ventilation at expanded position completely, so operation
During need patient to feel suffocated, it usually needs repeated multiple times operation, influence control effect and extended treatment time, or even part are suffered from
Person, which is difficult to coordinate, to complete.The danger of asphyxia is easily especially brought to patient during centre type airway constriction in the treatment.Also have
Short run effect can, but act on it is not lasting.
The country also has to research and develop to this：Such as Han Xinwei utility models dare to " the ventable formula under hard bronchoscope
Tracheae balloon expandable sheath ", this sheath pipe diameter is thicker, there is the tube chamber of ventilation, and near-end has side opening, can be ventilated during expansion.But
Need to operate under general anesthesia, only hard bronchoscope." a kind of airway that Micro Tech(Nanjing) Co., Ltd develops
The adjustable Airway dilation sacculus of diameter ", expands the internal diameter of conventional dilating sacculus airway tube to more than 4mm, and be described as hard
Operated under airway wall.2 kinds of sacculus of the above are difficult to by less airway constriction position and individually indwelling can not carried out in internal
Long period expansion (need to together with hard bronchoscope end operation).And there is complex operation, it is necessary to general anesthesia and coordinate
Using Rigid bronchoscope, the potential complication risk of patient is added, and the technical merit and hospital's hardware to medical worker are set
Standby to propose not high present of higher requirement, especially Rigid bronchoscope equipment popularity rate, hospital uses the difficulty of this equipment
It is larger.
The defect of above-mentioned balloon expandable device significantly limit application of the balloon expanding technology in treatment of airway constriction.
