Description
Technical Field
The utility model relates to a medical apparatus, in particular to a visual stereoplasm bronchoscope of paediatrics.
Background
The clinical application of the hard bronchoscope (RB) has been over one hundred years, the hard bronchoscope can be widely applied to diagnosis of congenital diseases of trachea and bronchus, tuberculosis, bronchial foreign bodies and the like, has a wide application range on diagnosis and treatment of scabs and tumors in the bronchus, contributes to diagnosis and treatment of a plurality of respiratory diseases, and can be applied to children along with scientific progress, so that the hard bronchoscope has irreplaceable positions in work of taking out the bronchial foreign bodies, placing silicone stents and the like.
The existing pediatric hard bronchoscope adopts a design that a sight glass and a bronchoscope sheath tube are independently operated. Because of the restriction of the diameter of the trachea of the child, the sheath tube of the bronchoscope is thin, the most widely used STORZ hard scope in China is taken as an example, the thinnest hard scope is inserted into the sheath tube with the outer diameter of only 5.0mm, and the visual scope is 2.9mm, so that the situation that the visual scope and the operation instrument cannot be used together is caused, and the accuracy of the operation is seriously influenced. Even if optical visual forceps can be used for the hard glasses with the diameter of more than 5.7mm, the visual and operational performances are considered, but the instrument is heavy, the operability is poor, visual release can not be achieved at any time in the release link of the silicone support (the same problem exists in adults), and the same problem exists in other brands of hard glasses at present. The children have fine air passages, the air pipe structure is not developed and perfected, and the defect of the existing hard mirror can seriously affect the operation effect and even can cause serious side damage.
However, as medicine develops, hard glasses are also developing and perfecting, and part of functions cannot be replaced by bronchofiberscope. Ventilation dysfunction is generally not caused for healthy adults, but may be affected and even life-threatening for children or those with airway constriction. Therefore, the hard bronchoscope, especially the hard bronchoscope for pediatrics, still has other status such as bronchofiberscope, electronic scope, etc. which cannot be replaced, and the development of modern interventional airway diagnosis and treatment technology brings new lives for the hard bronchoscope.
In recent decades, flexible bronchoscopes (bronchofiberscopes and electronic bronchoscopes) are more and more widely popularized and applied in clinic along with the technical progress, compared with hard scopes, the bronchofiberscopes are smaller in diameter, the head end portions of the bronchofiberscopes are designed to be bent controllably, and the bronchofiberscopes can reach parts which are difficult to reach to observe, so that the bronchofiberscopes are widely applied, and the hard scopes are developed more slowly.
The demand for hard glasses has increased over the last decade with the rapid development of interventional respiratory pathology. Compared with a bronchofiberscope, the hollow structure of the hard scope can keep an airway smooth, and a side hole is formed in the operation end and connected with a respirator, so that the hard scope is also called as a ventilation bronchoscope, and the bronchofiberscope needs to occupy a certain airway space in the operation process. And the operation pore canal under the hard mirror is obviously larger than that of the bronchofiberscope, so that various interventional treatments can be carried out. Therefore, modern hard bronchoscopes have been developed to a certain extent in recent years. The imaging system provides an observation visual field for an operator by reflecting the far-end illumination target surface through the prism, and can directly observe the throat and even the airway through the lumen so as to facilitate intubation, attraction and treatment of foreign bodies.
The main structure is a hollow stainless steel tube with uniform tube diameter, the operation end is provided with a plurality of interfaces, including a breathing machine interface, a light source interface, a suction tube, a laser fiber interface and the like, the current international existing hard bronchoscope is a mainstream brand represented by STORZ, wolf brand, Stryker and DUMON, the design concept is different, and the design that two parts of a sight glass and a bronchoscope sheath tube are independently operated is adopted. Adult's hard mirror is because the sheath pipe is thick, and visibility and operability are compatible better, but paediatrics is because the sheath pipe is fine, and visibility and operability are compatible relatively poor, though obtain partial improvement through equipment such as the visual pincers of optics, still have very big not enough.
The silicone support enters the Chinese market in 2014, the placement of the silicone support needs to be completed through a hard mirror, all placement processes are operated under non-visual conditions, the support part to be placed can only be explored firstly, then the support is placed in a stainless steel pipe cavity after a visual light source is taken out, the air passage of the support is placed under the blind operation condition, and the visual light source is placed for exploration after the operation is completed. The error of the placement position is easily caused by blind operation, the treatment effect is influenced, the air passage damage is easily caused, and the operation time is prolonged.
Therefore, the main development direction of the existing hard bronchoscope is to develop the hard bronchoscope with the visualization function, the visualization is realized during the operation, the operation accuracy is improved, the medical risk is reduced, but the tube diameter is thick, the tube cannot be bent, the visual range is small, the pain of a patient is large, and therefore the application of the hard bronchoscope is obviously reduced.
