Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a direct-view percutaneous dilatation tracheotomy indicator mirror. Background Art

[0002] Most critically ill patients require mechanical ventilation. Some cannot be separated from ventilator assistance in the short term, or require long-term mechanical ventilation or artificial airway management, and need tracheotomy to establish an artificial airway. There are currently two commonly used methods of tracheotomy, including open tracheotomy (operational dilatation tracheotomy, OT) and percutaneous dilative tracheostomy (percutaneous dilative tracheostomy, PDT). Percutaneous dilative tracheostomy has been gradually widely used in intensive care units due to its advantages of less surgical trauma, simple operation, short time, less bleeding, and fewer complications. However, it is also limited in the application of tracheotomy because it cannot be directly viewed and blindly operated, and may cause complications such as incorrect placement in the space around the trachea, tearing of the tracheal cartilage ring, damage to the posterior wall of the trachea, and subcutaneous emphysema.

[0003] Fiberbronchoscope guided percutaneous dilatation tracheotomy (FBPDT) can monitor the position of the puncture needle and guidewire under direct vision, which can largely avoid the risk of surgical operation, reduce complications and improve the success rate. However, FBPDT requires a dedicated person to operate the fiberbronchoscope, which increases the labor cost. In addition, the bedside operation space is limited, and too many people will cause inconvenience to the operation to a certain extent. In addition, the bronchoscope and the endotracheal tube will slide relatively, and the field of vision is unstable. The method of one person operating the bronchoscope and the other operating the endotracheal tube requires a high degree of cooperation between the two people, which increases the difficulty of operation. Therefore, it is urgent to propose a direct vision percutaneous dilatation tracheotomy indicator mirror to solve this problem. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, a direct vision percutaneous dilatation tracheotomy indicator mirror is proposed to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: The percutaneous dilatation tracheotomy indicator mirror under direct vision comprises an indicator mirror body, the indicator mirror body comprises a catheter, a viewfinder camera is arranged at the lower end of the catheter, the upper end of the catheter is connected to a data cable through an electronic unit, the other end of the data cable is connected to a display screen, and a fixing piece is arranged on the catheter. The catheter can be a disposable catheter or a reusable catheter, and the catheter is bendable.

[0006] As a further technical solution of the present invention: the fixing member is a fixing bolt, and the fixing bolt is arranged on the outer periphery of the catheter.

[0007] As a further technical solution of the present invention: a three-hole connector is provided at the upper end of the catheter, a negative pressure suction working channel is provided in the catheter, the upper end of the negative pressure suction working channel is connected to a negative pressure connection port, the negative pressure connection port is provided on one side of the three-hole connector, and an electronic unit is connected to the other side of the three-hole connector.

[0008] Beneficial effects of the present invention: The indicator mirror of the present invention comprises a catheter, a viewfinder camera is also arranged at the lower end of the catheter, and a wide-angle light source is arranged at the inner opening, which can clearly illuminate the target visual field; the upper end of the catheter is connected to a data line through an electronic unit, and the other end of the data line is connected to a display screen, and an external display screen is connected, so that all operators can view the visual field. The present invention has a simplified structure and a compact size, greatly improves clinical operability, and reduces costs.

[0009] The present invention is used in conjunction with an endotracheal cannula, wherein the catheter is arranged inside the endotracheal cannula, the lower end of the catheter is flush with the lower end of the endotracheal cannula, the upper end of the catheter passes through the endotracheal cannula, and the catheter and the upper end of the endotracheal cannula are fixed by a fixing member, and the fixing member fixes the indicator mirror body to the endotracheal cannula, so that the two do not slide relative to each other, thereby ensuring that the inner opening of the indicator mirror body (viewing camera) is always located at the tip of the endotracheal cannula, and the field of view is stable. As the endotracheal cannula is withdrawn, the indicator mirror body is withdrawn accordingly, thereby reducing unnecessary stimulation to the patient, and avoiding the phenomenon in the prior art that one person operates the endotracheal cannula and the other person operates the bronchoscope, and the asynchronous withdrawal causes stimulation to the airway wall, resulting in choking and coughing of the patient, and increasing the patient's discomfort.

[0010] After the indicator mirror body of the present invention is fixed to the endotracheal tube, there is no need for a dedicated person to operate the indicator mirror body, which saves labor costs and space, simplifies the operation process, increases the operating comfort, and retains the advantage of visualizing the operation process. The design is simple and smart, does not affect ventilation, and tracheotomy can be guided under direct vision, and clinical application is safe and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0014] Reference Figure 1-5 , a percutaneous dilatation tracheotomy indicator mirror under direct vision includes an indicator mirror body 2, which is used in conjunction with an endotracheal tube 1, and the indicator mirror body 2 is arranged in the endotracheal tube 1. The endotracheal tube 1 includes a tube body 11, and the upper part of the tube body 11 is a joint 12. The endotracheal tube 1 is a prior art, and the lower end of the tube body 11 is an oblique guide head, and the lower part of the tube body 11 is also provided with components such as a balloon. The joint 12 is connected to a connecting tube 14 through a connector 13, and an end cap 15 is provided at the upper end of the connecting tube 14, and a small hole 16 is opened on the end cap 15, and a cap body 17 is detachably connected to the small hole 16, and one side of the connecting tube 14 is also connected to a ventilator pipeline. When in use, the lower part of the endotracheal tube is inserted into the human trachea 6.

[0015] The indicator mirror body 2 includes a catheter 21, which passes through the small hole 16 and enters the interior of the endotracheal tube 1. The lower end of the catheter 21 is flush with the lower end of the endotracheal tube 1. A viewfinder camera 26 is also provided at the lower end of the catheter 21. The viewfinder camera 26 will not pass through the endotracheal tube 1. The viewfinder camera 26 has a wide-angle light source at its inner opening, which can clearly illuminate the target field of view. It is used in conjunction with an electronic endoscope image processor for endoscopic examination inside the endotracheal tube. After the upper end of the catheter 21 passes through the endotracheal tube 1, it is connected to a data line 23 through an electronic unit 22. The other end of the data line 23 is connected to a display screen 24, which can be used by all operators to view the field of view.

[0016] The catheter 21 is fixed to the upper end of the endotracheal tube 1 by a fixing member 25. After the catheter 21 is adjusted to the appropriate position of the tube body 11, the fixing member 25 fixes the catheter 21 to the endotracheal tube 1. The fixing member 25 is a fixing bolt, which is arranged on the outer periphery of the catheter 21. When the lower end of the catheter 21 is flush with the lower end of the endotracheal tube 1, the fixing bolt is just stuck in the small hole 16 to fix the two. It can also be fixed by other fixing members 25, such as fixing buckles and other fixing members 25. The positions of other fixing members can be changed according to actual conditions, and other fixing members 25 are not necessarily arranged in the small hole 16.

[0017] The specific implementation method is as follows: first, the patient is disinfected and the subcutaneous tissue is bluntly separated; the data cable 23 is connected to the display screen 24; the catheter 21 is inserted into the endotracheal tube 1, and when the lower end of the catheter 21 is flush with the lower end of the endotracheal tube 1, the fixing bolt is just stuck in the small hole 16 to fix the two; then the operation is performed, and during the operation, the viewfinder camera 26 keeps shooting the internal situation and displays it through the display screen 24, which is convenient for the surgical operation. The visualization advantage makes the operation process safer and can greatly reduce related complications.

[0018] At the same time, compared with the percutaneous dilation tracheotomy under the guidance of a fiber bronchoscope, which requires a dedicated person to operate the fiber bronchoscope, this application fixes the catheter 21 and the tracheal tube 1 at the fixing part 25, and the catheter 21 and the tracheal tube 1 will not be relatively displaced; and during the operation, there is no need for a dedicated person to operate the bronchoscope 2, which saves labor costs. Only one person is needed to operate the tracheal tube 1 and the indicator mirror body 2 at the same time, avoiding occupying the operating space and affecting other operators. Example
