Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a tracheal tube for vocal cord surgery. Background Art

[0002] Vocal cord surgery includes vocal cord polyp clamping and laryngeal papilloma resection. Before surgery, the patient needs to be in an awake state and undergo electronic laryngoscopy to determine the size and location of vocal cord polyps and laryngeal papilloma. This type of surgery often requires endotracheal intubation and mechanical ventilation after general anesthesia to ensure the patient's oxygen supply. After general anesthesia, the patient's muscles relax and the tension of the vocal cords changes. In addition, the endotracheal intubation passes through the glottis, which changes the position of the vocal cord polyps and laryngeal papilloma that were originally obtained by electronic laryngoscopy when the patient is awake, and often manifests as curling into the glottis. This change makes it difficult for surgeons to find the lesion under supported laryngoscopy. The surgeon needs to constantly pull the vocal cords to find the lesion, which causes unnecessary damage to the patient.

[0003] Furthermore, in the prior art, when surgically removing the lesion, there is a risk of foreign matter and blood accidentally entering the trachea, causing secondary injury. Summary of the invention

[0004] Purpose of the invention: To overcome the defects of the prior art, the present invention provides a tracheal tube for vocal cord surgery which is helpful for finding the lesion site.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A tracheal catheter for vocal cord surgery comprises a hollow main catheter, a closed air bag arranged near the head end of the main catheter, and a catheter joint arranged at the tail end of the main catheter, characterized in that a vocal cord activation air bag close to the closed air bag is arranged on the outer peripheral side of the main catheter, the vocal cord activation air bag is located on the side of the closed air bag facing the tail end of the main catheter, the vocal cord activation air bag is connected to an air injection tube, one end of the air injection tube is connected to the vocal cord activation air bag, and the other end of the air injection tube is provided with a valve core.

[0007] The method for using the tracheal catheter for vocal cord surgery of the present invention is as follows: the main catheter is inserted when the vocal cord moving airbag is in an uninflated state, suction can be performed under the glottis, the vocal cord moving airbag is fully inflated, and then the catheter is withdrawn, thereby moving the internally curled glottic polyp, which is beneficial for finding the lesion site; the airbag is used to move the glottis, which is more convenient and gentle to operate, improves the safety and reliability of the surgical operation, and reduces the risk of damage to the patient; after the lesion site is found, the gas in the vocal cord moving airbag is extracted, and the closed airbag is filled with gas to complete the main function of the tracheal catheter.

[0008] Preferably, the vocal cord moving airbag is located in a quarter quadrant of the main conduit. This structural design is convenient for operation.

[0009] Preferably, the longitudinal cross-section of the vocal cord-moving airbag in the filled state is triangular or trapezoidal, and the smaller end of the vocal cord-moving airbag is away from the closed airbag, and the top surface of the vocal cord-moving airbag in the filled state is a downward slope from one end close to the closed airbag to the other end obliquely attached to the main duct wall. Under this structural design, the vocal cord-moving airbag is easy to operate to move the glottis, which is easy to operate.

[0010] Preferably, the end surface of the vocal cord stirring airbag in the filled state is inclined from the end connected to the main conduit to the other end close to the closed airbag. Under this structural design, the tail end of the vocal cord stirring airbag becomes thinner, which makes the stirring of the vocal cord polyp gentler and reduces the damage to the vocal cord polyp.

[0011] Preferably, the gas injection pipe is provided with an indicator bag, and the valve core is arranged on the indicator bag. Under this structural design, the indicator bag plays an indicating and buffering role.

[0012] Preferably, the suction hole is provided on the outer wall of the main catheter, and is located on the side of the closed airbag close to the vocal cord moving airbag, and the suction hole is close to the closed airbag, and the suction hole is connected to a suction tube extending along the main catheter to the tail end of the main catheter. Under this structural design, when the closed airbag is filled to seal the trachea, there is also secretion on the side of the closed airbag away from the insertion end, and the secretion is sucked out through the suction hole and the suction tube.

[0013] The present invention will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of a tracheal tube for vocal cord surgery according to a specific embodiment of the present invention. DETAILED DESCRIPTION

[0015] See attached Figure 1The present invention discloses a tracheal catheter for vocal cord surgery, comprising a hollow main catheter 1, a closed airbag 2 arranged near the head end of the main catheter 1, and a catheter joint 3 arranged at the tail end of the main catheter 1. The head end of the main catheter 1 is an insertion end, and the port is usually an oblique incision 11. The closed airbag 2 is connected to an inflatable thin hose 2-1, a part of which is buried in the main catheter 1 and leads to the closed airbag 2. The inflatable thin hose 2-1 passes through the outer side of the tube wall of the main catheter 1 and is provided with a valve core, which is not shown in the figure. The closed airbag 2 is inflated and the gas in the closed airbag 2 is extracted through the valve core. A vocal cord stirring airbag 4 close to the closed airbag 2 is provided on the outer peripheral side of the main catheter 1. The vocal cord stirring airbag 4 is located on the side of the closed airbag 2 facing the tail end of the main catheter 1. The vocal cord stirring airbag 4 is connected to an injection tube 4-1, one end of the injection tube 4-1 is connected to the vocal cord stirring airbag 4, and the other end of the injection tube 4-1 is provided with a valve core. The gas injection tube 4-1 is provided with an indicator bag 4-2, and the valve core is provided on the indicator bag 4-2; the indicator bag 4-2 plays an indicating and buffering role. The valve core is a conventional component, that is, a valve structure, so its specific structure is not repeated in this specific embodiment. The gas injection tube 4-1 is blocked in a free state, and when the glottis is inflated or the gas in the glottis is extracted, a corresponding operating tool such as a syringe is connected to the valve core to realize the valve core opening state.

[0016] Furthermore, the vocal cord moving airbag 4 is located in a quarter quadrant of the main conduit 1. The vocal cord moving airbag 4 is small in size, and is convenient for being placed under the curled glottic polyp to perform corresponding moving operations, thereby increasing the operating space and reducing the squeezing damage to the vocal cord polyp.

[0017] The longitudinal cross-section of the vocal cord moving airbag 4 in the filled state is a triangle or a trapezoid, and the smaller end of the vocal cord moving airbag 4 is away from the closed airbag 2. Correspondingly, in the filled state of the vocal cord moving airbag 4, the top surface is a downslope surface 42 that is obliquely attached to the wall of the main conduit 1 from one end close to the closed airbag 2 to the other end. The vocal cord moving airbag 4 is easy to operate to move the glottis, which is easy to operate. In this specific embodiment, it is a triangle. The movement of the vocal cord polyp is more gentle, reducing damage to the vocal cord polyp.

[0018] The end surface 411 of the raised end 41 of the vocal cord stirring airbag 4 in the filled state extends obliquely from the end connected to the main conduit 1 to the other end close to the closed airbag 2. Under this structural design, the tail end of the vocal cord stirring airbag becomes thinner, and the stirring of the vocal cord polyp is gentler, reducing the damage to the vocal cord polyp.

[0019] In this specific embodiment, the outer wall of the main catheter 1 is provided with a suction hole 12, which is located on the side of the closed airbag 2 close to the vocal cord moving airbag 4, and the suction hole 12 is close to the closed airbag 2. The suction hole 12 is connected to a suction tube 13 extending along the main catheter 1 to the tail end of the main catheter 1. Under this structural design, when the closed airbag 2 seals the trachea after being filled, secretions are also retained on the side of the closed airbag 2 away from the insertion end, and the secretions are sucked out through the suction hole 12 and the suction tube 13. The suction tube 13 is partially buried in the main catheter 1, one end of the part of the suction tube 13 buried in the main catheter 1 is connected to the suction hole 12, and the other end of the part of the suction tube 13 buried in the main catheter 1 extends and passes through the outer wall of the main catheter 1 and is provided with a joint 131.

[0020] The method for using the tracheal tube for vocal cord surgery of the present invention is as follows: the main tube 1 is inserted when the vocal cord moving airbag 4 is in an uninflated state, suction can be performed under the glottis to fully inflate the vocal cord moving airbag 4, and then the tube is withdrawn, thereby moving the inwardly curled glottis, which is beneficial for finding the lesion site; using the airbag to move the glottis makes the operation more convenient and gentle, improves the safety and reliability of the surgical operation, and reduces the risk of harm to the patient; after completing the search for the lesion site, the gas in the vocal cord moving airbag 4 is extracted, and the closed airbag 2 is filled with gas to complete the main functions of the tracheal tube.
