Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel tracheal tube which can be used for cooling the trachea during surgery. Background Art

[0002] Tracheal tumor resection surgery often requires the use of energy instruments for cutting and hemostasis, such as electrocoagulation hooks, high-frequency electrosurgeries, ultrasonic scalpels and other energy instruments. However, while these instruments can effectively cut and stop bleeding on the tracheal tissue, they also generate a lot of heat and high temperature, which can cause high-temperature burns to the tracheal tissue being operated on, and can even cause poor healing or ulcers at both ends of the sutured trachea after surgery. Therefore, how to effectively cool down the human tracheal tissue during the resection of tracheal tumors has become a key clinical problem that needs to be solved urgently. To this end, we propose a new tracheal tube that can be used for intraoperative tracheal cooling. Utility Model Content

[0003] The utility model aims to provide a novel tracheal tube which can be used for cooling the trachea during surgery, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of tracheal catheter that can be used for intraoperative tracheal cooling, comprising a tracheal catheter, a front end surface of the tracheal catheter is fixedly connected to an air bag, an inner wall of the tracheal catheter is fixedly connected to an inflation tube, one end of the inflation tube is connected to the air bag, and the other end of the inflation tube passes through the rear end of the tracheal catheter, a cooling bag is fixedly connected to the surface of the tracheal catheter, the cooling bag is located at the rear end of the air bag, an infusion tube is fixedly connected to the inner wall of the tracheal catheter, one end of the infusion tube passes through the rear end of the tracheal catheter, and the infusion tube is used to inject cold water into the inner wall of the cooling bag.

[0005] Preferably, the cooling bag is arranged in a ring shape and wrapped around the front end surface of the endotracheal tube.

[0006] Preferably, the surface of the cooling bag is provided with a fracture groove.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: through the structural arrangement of the cooling bag, the infusion tube, and the fracture groove, after the tracheal tube is inserted into the patient's airway, cold water is injected into the cooling bag through the infusion tube, so that the cooling bag expands in volume and contacts the surface of the inner wall of the trachea at the cutting position, further absorbing heat and cooling the tracheal tissue around the cutting position, thereby preventing the tracheal tissue around the cutting position from being burned by the high temperature generated by the operation of the energy device.

[0011] Example

[0012] See also Figure 1-2 , the utility model provides a technical solution:

[0013] A new type of tracheal tube that can be used for intraoperative tracheal cooling, wherein the front end surface of the tracheal tube 1 is fixedly connected with an airbag 2, the inner wall of the tracheal tube 1 is fixedly connected with an inflation tube 3, one end of the inflation tube 3 is connected with the airbag 2, and the other end of the inflation tube 3 passes through the rear end of the tracheal tube 1. After the front end of the tracheal tube 1 is inserted into a suitable position inside the patient's airway, air is inflated into the interior of the airbag 2 through the inflation tube 3, and the volume of the airbag 2 is further expanded after being inflated and contacts the inner wall of the airway, thereby achieving the fixation of the airbag 2 inside the patient's airway, and facilitating the subsequent cooling operation during the removal of the patient's tracheal tumor.

[0014] A cooling bag 4 is fixedly connected to the surface of the tracheal tube 1. The cooling bag 4 is located at the rear end of the airbag 2. At the same time, an infusion tube 5 is fixedly connected to the inner wall of the tracheal tube 1. One end of the infusion tube 5 penetrates the tail end of the tracheal tube 1. Cold water can be injected into the inner wall of the cooling bag 4 through the infusion tube 5. After the tracheal tube 1 is inserted into the patient's airway, the cooling bag 4 is controlled to be flush with the tracheal tumor on the inner wall of the patient's airway, and the airbag 2 further fixes the tracheal tube 1 to the inner wall of the patient's airway. When the medical staff removes the patient's tracheal tumor through the energy device, the cooling bag 4 is filled with cold water and expands in volume, so that the cooling bag 4 contacts the surface of the tracheal inner wall at the cutting position, further absorbing heat and cooling the tracheal tissue around the cutting position, and preventing the tracheal tissue around the cutting position from being burned by the high temperature generated by the operation of the energy device.

[0015] At the same time, the cooling bag 4 is set to be annularly wrapped around the front end surface of the tracheal tube 1, so that when the medical staff uses the energy device to remove the patient's tracheal tumor, the cooling bag 4 wraps the tracheal tube 1 at the cutting position to avoid the heat generated by the energy device causing the tracheal tube 1 to be burned, resulting in leakage inside the tracheal tube 1. The surface of the cooling bag 4 is provided with a fracture groove 6, through which a gap can be formed between the cooling bag 4 and the inner wall of the patient's airway. By controlling the tracheal tube 1 to rotate inside the patient's airway, the fracture groove 6 and the tracheal tumor are aligned, which further facilitates the medical staff to hold the energy device to remove the tracheal tumor. After the removal is completed, the tracheal tube 1 is controlled to rotate so that the fracture groove 6 and the position after the tracheal tumor is cut are staggered, and the cooling bag 4 is controlled to contact the position after the tracheal tumor is cut, so that the rapid cooling of the tracheal tumor cutting position can be achieved.
