Description

Tracheal cannula for laryngoscope operation

Technical Field

The utility model relates to the field of medical equipment, in particular to an endotracheal intubation used for laryngoscope operation.

Background

The supporting laryngoscope operation is a minimally invasive operation which is completed by using a special supporting laryngoscope bracket and matching with an endoscope light source and a refined instrument to reach the throat through the oral cavity and the oropharynx after general anesthesia and tracheal intubation of a human body. The operation is completed by the natural cavity of the human body reaching the throat, has the remarkable characteristics of no scar on the body surface and quick postoperative recovery, is widely applied to surgical excision of benign lesions of the throat of the human body, and has certain advantages for early laryngeal cancer and the like. Because the space of the throat cavity of a human body is narrow and small, the trachea cannula can occupy most of the space after general anesthesia to cause the occlusion of the surgical field, so that the operation often needs a surgeon to spend a great deal of time and energy to expose and operate pathological changes, and the operation process is seriously influenced.

Before the current self-retaining laryngoscope operation, the trachea cannula that the pipe diameter is thinner is settled to the doctor of mostly meeting the advice anesthesia of surgeon when the general anesthesia intubate in order to reduce the sheltering from to the operation field, and this kind of way has certain effect to going on larynx both sides vocal cord operation, but then does not have the effect to the preceding cooperation of larynx, the fine operation of ring arytenosis joint etc. department, urgent need further optimization and improvement.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides an endotracheal tube for use in laryngoscope procedures. The utility model has the advantages of make the art field of supporting the laryngoscope operation expose more abundant, shorten the operation time greatly, reduce surgeon's the operation degree of difficulty, the principle is simple, and the cost of manufacture is lower, can popularize and use in going the patient operation of supporting the laryngoscope.

The technical scheme of the utility model is that:

the utility model provides an endotracheal tube for supporting laryngoscope operation, includes pipe shaft, endotracheal tube core, annular gasbag device and at least one fan-shaped gasbag device, fan-shaped gasbag device includes first one-way inflation valve, first inflation line and fan-shaped gasbag, fan-shaped gasbag is established keeping away from human one end of pipe shaft, the one end of inflation line links to each other with fan-shaped gasbag, and the other end links to each other with one-way inflation valve, the endotracheal tube core is established inside the pipe shaft, the length of endotracheal tube core is greater than the length of pipe shaft, the one end of keeping away from human of endotracheal tube core extends the pipe shaft.

The working principle of the scheme is as follows:

after the trachea cannula is inserted into the patient, the annular air bag is inflated to prevent airway secretion from flowing into the lung, the trachea cannula is rotated to enable the fan-shaped air bag to be placed on the affected side, and when an operation is performed, the fan-shaped air bag is inflated to enable the trachea cannula to be inclined towards the healthy side to the maximum degree to expose the operative field.

In a further technical scheme, the annular air bag device comprises a second one-way inflation valve, a second inflation line and an annular air bag, the annular air bag is arranged at one end, inserted into a human body, of the trachea cannula, one end of the inflation line is connected with the annular air bag, and the other end of the inflation line is connected with the one-way inflation valve.

The annular air bag is arranged at the trachea, so that air passage secretion or blood is prevented from flowing into the lung to cause pollution.

In a further technical scheme, the radian of the contact surface of the fan-shaped air bag and the tube body is 90 degrees.

The radian of the contact surface of the fan-shaped air bag and the tube body is 90 degrees, which is beneficial to exposing the operative field during the operation, if the arc surface is too big, the air bag can shield the operative field, and if the arc surface is too small, the tube body can be deflected insufficiently to expose the operative field.

The utility model has the advantages that:

1. the surgical field of the self-supporting laryngoscope operation is more fully exposed, the operation time is greatly shortened, the operation difficulty of a surgeon is reduced, the principle is simple, the manufacturing cost is lower, and the self-supporting laryngoscope can be popularized and used in the patient operation of the self-supporting laryngoscope.

2. The annular air bag is arranged at the trachea, so that air passage secretion or blood is prevented from flowing into the lung to cause pollution.

3. The radian of the contact surface of the fan-shaped air bag and the tube body is 90 degrees, which is beneficial to exposing the surgical field during the operation.

Drawings

FIG. 1 is a schematic view of an endotracheal tube for use in supporting laryngoscope operations according to the present embodiment.

Description of reference numerals:

1. a first inflation line; 2. a first one-way inflation valve; 3. a tracheal cannula core; 4. a fan-shaped air bag; 5. a tube body; 6. an annular air bag; 7. a second inflation line; 8. a second one-way inflation valve.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

Example (b):

as shown in figure 1, a trachea cannula for supporting laryngoscope operation, including pipe shaft 5, trachea cannula tube core 3, annular gasbag device and at least one fan-shaped gasbag device, fan-shaped gasbag device includes first one-way inflation valve 2, first inflation line 1 and fan-shaped gasbag 4, and fan-shaped gasbag 4 is established human one end is kept away from to pipe shaft 5, and the one end of inflation line links to each other with fan-shaped gasbag 4, and the other end links to each other with one-way inflation valve, and the trachea cannula tube core is established inside pipe shaft 5, and the length of trachea cannula tube core is greater than the length of pipe shaft 5, and the one end of keeping away from the human body of trachea cannula tube core extends pipe shaft 5.

The working principle of the scheme is as follows:

after the patient is intubated, inflate annular gasbag 6, prevent that air flue secretion from flowing into the lung, rotatory intubate makes fan-shaped gasbag 4 arrange in the affected side, when the operation, inflates fan-shaped gasbag 4, thereby makes trachea cannula incline to the side of being good for the biggest show art field.

In another embodiment, the annular air bag 6 device comprises a second one-way inflation valve 8, a second inflation line 7 and an annular air bag 6, the annular air bag 6 is arranged at one end of the tracheal cannula inserted into the human body, one end of the inflation line is connected with the annular air bag 6, and the other end of the inflation line is connected with the one-way inflation valve.

The annular air bag 6 is arranged at the trachea, so that air passage secretion or blood is prevented from flowing into the lung to cause pollution.

In another embodiment, the arc of the contact surface of the fan-shaped air bag 4 and the tube body 5 is 90 degrees.

The radian of the contact surface of the fan-shaped air bag 4 and the tube body 5 is 90 degrees, which is beneficial to exposing the operative field during the operation, if the arc surface is too big, the air bag can shield the operative field, and if the arc surface is too small, the tube body 5 can be caused to be not inclined enough to expose the operative field enough.
