Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, specifically to a tracheal tube for tracheal carina resection and reconstruction. Background Technology
[0002] Carina resection and reconstruction is one of the most complex procedures in tracheal surgery. The tracheal carina has a "V"-shaped structure, and the surgery often requires cutting all three ends and reanastomosing the trachea. Because the endotracheal tube passes near the carina, the ventilation mode needs to be adjusted intraoperatively according to the progress of the surgery. The anesthesiologist and surgeon must work together to maintain ventilation for the patient. The anesthesiologist provides ventilation through the conventional oral-tracheal route, while the surgeon provides ventilation by directly inserting a sterile endotracheal tube into one lung in the surgical field. With the development of surgical techniques, traditional open-chest surgery is gradually being replaced by minimally invasive thoracoscopic surgery. During tracheal carina resection and reconstruction, it is difficult for surgeons to directly ventilate the patient in the surgical field. Inserting the endotracheal tube through the narrow thoracoscopic port can interfere with and interrupt the surgical procedure, and the conventional oral-tracheal route does not allow for direct intraoperative adjustment of the patient's ventilation mode. Summary of the Invention

[0007] In conjunction with the first aspect, in one embodiment, the clamping part includes a clamping airbag connected to the connector; the clamping airbag is also connected to a first air tube, the first air tube is attached to the inner wall of the main tube and extends along the axial direction of the main tube, and one end of the first air tube away from the clamping airbag passes through the opening of the main tube.
[0008] In conjunction with the first aspect, in one embodiment, the main tube is connected to a second air tube, the second air tube is installed on the side wall of the main tube, the second air tube communicates with the main airbag, and the second air tube extends along the axial direction of the main tube, with one end of the second air tube away from the main airbag passing through the opening of the main tube.

[0013] The beneficial effects of the technical solutions provided in this application include:
[0014] By placing at least two independent bronchioles in the main tube, the main tube can be inserted through the patient's mouth, and each bronchiole in the main tube can be controlled independently.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.
[0027] This application provides an endotracheal tube for tracheal carina resection and reconstruction, which solves the technical problem in related technologies where it is difficult for surgeons to directly ventilate patients in the surgical field during minimally invasive thoracoscopic surgery, and the oral-tracheal tube placement method is not convenient for adjusting the patient's ventilation mode during surgery.
[0028] See Figure 1The image shows a tracheal tube for tracheal carina resection and reconstruction provided in an embodiment of this application. It may include: a main tube 1, with openings at both ends, and a main cuff 11 fitted around the periphery of the main tube 1; at least two branch tubes 2, each independently extending through the main tube 1, with each branch tube 2 extending axially along the main tube 1 and both ends exiting the openings of the main tube 1. A cuff 21 is fitted around one end of each branch tube 2. In this embodiment, two branch tubes 2 are provided, which can respectively enter the patient's left and right bronchuses. In other embodiments, the number of branch tubes 2 may be three or more.
[0029] In this embodiment, at least two independent branch tubes 2 are provided in the main tube 1. The main tube 1 can be inserted into the patient's mouth, and each branch tube 2 in the main tube 1 can be controlled independently. Each branch tube 2 has a certain length and can be inserted into the main tube 1 from one end and extended from the other end. In the tracheal carina resection and reconstruction surgery, different branch tubes 2 can be guided into the patient's left bronchus or right bronchus through a fiberoptic bronchoscope. Then, with the cooperation of the main balloon 11 and the bronchus balloon 21, the ventilation of the patient's left lung, right lung, or both lungs can be controlled. The specific ventilation mode can be determined according to the surgical requirements. In this embodiment, by using an endotracheal tube, continuous ventilation via the oral-tracheal route can be maintained. The position of the endotracheal tube can be adjusted during the surgical procedure. Even in minimally invasive thoracoscopic surgery, where the incision diameter is small and inserting a traditional endotracheal tube is inconvenient, the surgical process is not affected. This solves the technical problems of difficulty in directly ventilating the patient in the surgical field and the inconvenience of adjusting the patient's ventilation mode intraoperatively using only oral-tracheal tube placement. Furthermore, using an endotracheal tube for tracheal carina resection and reconstruction can maintain uninterrupted ventilation throughout the surgery, ensuring patient safety, preventing hypercapnia, and protecting lung function.
[0030] In some optional embodiments, each of the branch tubes 2 is slidably mounted on the main tube 1 along its axial direction. Sliding the branch tubes 2 on the main tube 1 facilitates adjustment of their positions within the main tube 1, effectively matching the different depths of the left and right bronchuses during surgery, avoiding insertion that is too deep or too shallow, and allowing for temporary retraction of one or both branch tubes 2 during carina resection or reconstruction to avoid interfering with the surgical field. After completion, the corresponding branch tube 2 can be re-advanced to the target position.
[0031] In some optional embodiments, the endotracheal tube may further include a connector 31 and a clamping portion connected to the connector 31. The connector 31 is connected to the inner wall of the main tube 1, and the clamping portion is configured such that when the clamping portion clamps the branch tube 2, the branch tube 2 is relatively fixed to the main tube 1. It should be understood that using the clamping portion to hold the branch tube 2 can maintain the stability of the branch tube 2 during the operation, effectively preventing it from shifting during the operation and enhancing the safety of the operation. When the branch tube 2 needs to be moved, the clamping portion can be released from the clamp on each branch tube 2. Preferably, the connector 31 is connected to the inner wall of the main tube 1, that is, the clamping portion can also be set in the cavity of the main tube 1, reducing the overall size of the endotracheal tube, making the endotracheal tube more precise, and easier to operate during the operation.
[0032] See Figure 2 As shown, in some optional embodiments, the clamping part includes a clamping airbag 32 connected to the connector 31; the clamping airbag 32 is also connected to a first air tube 33, which is attached to the inner wall of the main pipe 1 and extends along the axial direction of the main pipe 1, with one end of the first air tube 33 away from the clamping airbag 32 passing through the opening of the main pipe 1. In this embodiment, the clamping airbag 32 is used to clamp or release the branch pipe 2. The clamping airbag 32 can be configured to retract radially along the main pipe 1, and it delivers or releases air through the first air tube 33. The first air tube 33 extends attached to the inner wall of the main pipe 1 to minimize the occupation of the cavity space of the main pipe 1. In some other embodiments, the first air tube 33 can also be accommodated in the side wall of the main pipe 1, that is, embedded in the side wall of the main pipe 1 and integrally formed with the main pipe 1. In this embodiment, the clamping airbag 32 can be precisely controlled by air pressure to achieve flexible fixation of the branch tube 2, avoiding excessive clamping that could cause deformation of the branch tube 2 or damage to the airway. Preferably, both the clamping airbag 32 and the clamping part can be provided in two sets, with the two sets of clamping airbags 32 spaced apart along the axis of the main tube 1, clamping the branch tube 2 at different heights to further enhance the stability of the branch tube 2.
[0033] In some optional embodiments, the main tube 1 is connected to a second trachea 12, which is installed on the side wall of the main tube 1. The second trachea 12 communicates with the main airbag 11 and extends axially along the main tube 1. One end of the second trachea 12, away from the main airbag 11, exits through the opening of the main tube 1. In this embodiment, the main airbag 11 is inflated by supplying air into it through the second trachea 12, and deflated by releasing gas from the main airbag 11 through the second trachea 12. In some other embodiments, the inflation and deflation of the main airbag 11 can also be achieved by connecting the main airbag 11 to a solenoid valve, which controls the connection or closure of the clamping airbag 32 with an external air source via an electrical signal. The second trachea 12 can exit the main tube 1 from its opening, allowing direct inflation of the second trachea 12 during surgery to inflate the main airbag 11. This method is relatively simple to operate, easy to implement, and simplifies the operation process. Preferably, the second trachea 12 can also be embedded in the side wall of the main tube 1 to save space in the main tube 1.
[0034] In some optional embodiments, a third trachea 22 is installed on the sidewall of each bronchus 2. The third trachea 22 communicates with the corresponding cuff 21. The third trachea 22 extends from the connection point with the cuff 21 toward the side away from the cuff 21, and the end of the third trachea 22 away from the cuff 21 exits through the opening of the bronchus 2. In this embodiment, the third trachea 22 may also be embedded in the sidewall of the corresponding bronchus 2 in an inlay manner and exit from the opening at the end of the bronchus 2 away from the cuff 21, so that it can be directly inflated or deflated by a syringe or air pump during the operation. The cuff 21 is positioned around the periphery of the corresponding bronchus 2. After the bronchus 2 is inserted into the bronchus during the operation, the corresponding cuff 21 can be inflated, so that lung air can flow out only through the corresponding cuff 21, so that the operation can be performed smoothly.
[0035] See Figure 3As shown, in some optional embodiments, the endotracheal tube further includes a main tube interface piece, which is detachably mounted on the end of the main tube 1 away from the bronchus cuff 21. The main tube interface piece allows the main tube 1 to be connected to a ventilator and may have connecting threads. Preferably, the main tube interface piece includes a mounting portion 41 and an interface portion 42 connected to the mounting portion 41. The mounting portion 41 is detachably connected to the opening of the main tube 1, and the interface portion 42 is coaxially arranged with the mounting portion 41. Both the interface portion 42 and the mounting portion 41 have receiving cavities, and the bronchus tube 2 is received within the receiving cavities. When the main connector is required, the mounting part 41 can be connected to the opening of the main connector 1. Its diameter is larger than that of the connector part 42. The thread can be provided in the connector part 42 to adapt to the connection of the ventilator. It should be understood that both the mounting part 41 and the connector part 42 have a receiving cavity. The end of each branch tube 2 away from the bronchus 21 can be inserted into the receiving cavity. When the connector part 42 is connected to the ventilator, the gas of the ventilator can directly enter each branch tube 2 from the connector part 42.
[0036] See Figure 4 As shown, in some optional embodiments, each branch tube 2 is detachably connected to a branch tube interface 5, which is installed at the end of the branch tube 2 away from the cuff 21. In this embodiment, the branch tube interface 5 is detachably connected to the end of each branch tube 2 away from the cuff 21, which allows each branch tube 2 to be individually connected to the ventilator to adapt to various situations during surgery and enhance the adaptability of the endotracheal tube.
[0037] Furthermore, the surgical steps of tracheal carina resection and reconstruction vary depending on the tumor location and anastomosis method. The left bronchus can be anastomosed with the corresponding bronchus 2 first, or the right bronchus can be anastomosed with the corresponding bronchus 2 first. In this embodiment, two bronchus 2s are used. During the operation, the two bronchus 2s are respectively inserted into the patient's left and right bronchuses. The bronchus 2 inserted into the patient's left bronchus is called the left bronchus 2, and the bronchus 2 inserted into the patient's right bronchus is called the right bronchus 2. Taking the patient's tumor located in the carina as an example, with the left main bronchus anastomosed with bronchus 2 first, and the right main bronchus anastomosed laterally, the specific intraoperative procedures using the tracheal tube for tracheal carina resection and reconstruction can be as follows: under anesthesia... After inducing endotracheal intubation and inserting the main endotracheal tube 1 into the designated position in the trachea, the main cuff 11 is inflated first, and both the left and right bronchus tubes 2 are retracted into the trachea to maintain bilateral lung ventilation. Under the guidance of a fiberoptic bronchoscope, the left bronchus tube 2 is inserted into the left main bronchus. Subsequently, the bronchus tube 21 on the left bronchus tube 2 is inflated, and the main cuff 11 is deflated to maintain single-lung ventilation of the left lung and collapse of the right lung. The right main bronchus is then disconnected, and the light spot of the fiberoptic bronchoscope tip is used to illuminate the trachea. The surgeon was guided to make a lateral incision. Then, right bronchus tube 2 was inserted through the tracheal lateral incision, and the stump of the right main bronchus was placed into the pleural cavity. The balloon 21 of right bronchus tube 2 was then inflated to maintain ventilation of the right lung. Subsequently, the balloon 21 of left bronchus tube 2 was deflated, and left bronchus tube 2 was withdrawn into the trachea, causing the left lung to collapse. The left main bronchus and part of the trachea were then severed, and the carina was removed. While maintaining one-lung ventilation of the right lung, the left main bronchus was anastomosed to the tracheal stump. After the left bronchus tube 2 was re-inserted and anastomosed... The left main bronchus stump is removed, and the bronchus cuff 21 of the left bronchus 2 is inflated to maintain single-lung ventilation of the left lung. Then, the bronchus cuff 21 of the right bronchus 2 is deflated, the right bronchus 2 is withdrawn into the trachea, the right lung collapses, and the right main bronchus stump is then anastomosed to the trachea through the tracheal side incision. After the anastomosis is completed, the main cuff 11 is inflated to completely remove the left and right tubes, and the main tube 1 is used to maintain double-lung ventilation. The patient can then return to the intensive care unit directly with this tracheal tube without having to replace it with another tracheal tube.
