Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a heated carbon dioxide blowpipe. Background Technology

[0002] During non-pump coronary artery bypass surgery, a carbon dioxide blowpipe is needed to clean the surgical field. Also, because carbon dioxide is highly soluble in water, it is less likely to form an air embolism. However, most heart centers currently use carbon dioxide cylinders to supply carbon dioxide, which results in the gas blown out of the blowpipe being relatively cold, which may cause coronary artery constriction. Utility Model Content

[0003] Therefore, this invention aims to solve the problem that the gas source blown out by the carbon dioxide blowpipe during cleaning the surgical field in non-stop bypass surgery is too cold and easily causes coronary artery vasoconstriction, thereby providing a heated carbon dioxide blowpipe.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A heated carbon dioxide blowing tube includes a distal output tube, a gas delivery tube, and a liquid delivery tube; a handle is sleeved on the distal output tube, and a heating structure located outside the distal output tube is provided inside the handle; one end of the gas delivery tube is adapted to communicate with a carbon dioxide cylinder, and the other end extends into the distal output tube; one end of the liquid delivery tube is adapted to communicate with a liquid storage bag, and the other end extends into the distal output tube.

[0006] Furthermore, the heating structure comprises a resistance wire and a power source electrically connected to the resistance wire and adapted to provide energy to the resistance wire.

[0007] Furthermore, it also includes a temperature control structure electrically connected to the heating structure.

[0008] Furthermore, the temperature control structure includes a temperature sensor and a temperature controller electrically connected to the temperature sensor; the temperature sensor is adapted to sense the temperature of the heating structure and feed the result back to the temperature controller; the temperature controller is adapted to adjust the power of the heating structure after receiving the temperature value output by the temperature sensor, thereby controlling the temperature of the heating structure.

[0009] Furthermore, the temperature control structure is adapted to stably control the heating structure between 30 and 45 degrees Celsius.

[0010] Furthermore, a flow regulator is provided on the infusion tube.

[0011] Furthermore, a flow-stopping clamp is provided on the gas pipeline.

[0012] Furthermore, a gas filter is installed on the gas pipeline.

[0013] Furthermore, an illumination element is provided at the end of the remote output pipe away from the gas supply pipe.

[0014] Furthermore, the resistance wire comprises any one of nickel-chromium alloy, tungsten-molybdenum alloy, and copper-nickel alloy.

[0015] The technical solution of this utility model has the following advantages:

[0016] 1. The heated carbon dioxide blowpipe provided by this utility model has a heating structure in the handle, which can heat the gas and liquid flowing through the distal output tube, reduce heat loss at the anastomosis site, and thus help maintain the patient's core body temperature and heart rate, thereby improving surgical safety; at the same time, it can prevent the gas blown out of the blowpipe from being too cold, which could cause vasoconstriction and lead to other complications.

[0017] 2. The heated carbon dioxide blowing pipe provided by this utility model has a heating structure consisting of a resistance wire and a power source electrically connected to and adapted to provide energy to the resistance wire. With this configuration, the resistance wire serves as the heating medium, leveraging its ability to rapidly heat up and quickly respond to temperature changes, enabling the liquid and gas passing through the distal output pipe to heat up quickly, thus ensuring heating efficiency.

[0018] 3. The heated carbon dioxide blowpipe provided by this utility model is equipped with a temperature control structure electrically connected to the heating structure. This configuration allows for temperature control of the heating structure, adjusting and controlling its temperature to meet different needs during surgery and improving surgical efficiency.

[0019] 4. The heated carbon dioxide blowpipe provided by this utility model has a temperature control structure suitable for stably controlling the heating structure between 30 and 45 degrees Celsius. This design keeps the heating temperature of the heating structure close to the body temperature, preventing the temperature of the gas blown out by the carbon dioxide blowpipe from being too high or too low. This reduces the overall temperature difference during surgery, which is beneficial for alleviating postoperative inflammatory reactions and promoting postoperative recovery.

[0020] 5. The heated carbon dioxide infusion tube provided by this utility model has a flow regulator installed on the infusion tube. This design allows for precise adjustment of the fluid flow rate within the infusion tube, enabling the flow rate to be adjusted according to different needs during surgery, thus facilitating more accurate surgical procedures.

[0021] 6. The heated carbon dioxide blowpipe provided by this utility model has a flow-closing clamp on the gas delivery pipe. This configuration allows for the control of the opening and closing of the carbon dioxide gas flow through the flow-closing clamp. Furthermore, the flow rate of the carbon dioxide gas within the gas delivery pipe can be adjusted by changing the degree of closure of the flow-closing clamp to meet different needs during surgery. Completely closing the flow-closing clamp prevents backflow of carbon dioxide gas, ensuring a stable gas environment in the surgical area and reducing complications during surgery.

[0022] 7. The heated carbon dioxide blowpipe provided by this utility model has a gas filter installed on the gas delivery pipe. This design allows impurities and potential microbial contamination in the supplied carbon dioxide gas to be removed by the gas filter, thereby ensuring that the gas delivered to the surgical area is clean and safe, and reducing the risk of infection at the surgical site.

[0023] 8. The heated carbon dioxide blowpipe provided by this utility model has an illumination element at the end of the distal output tube furthest from the gas delivery tube. This configuration can improve the illumination of the surgical anastomosis and solve the problem of insufficient brightness in the surgical field caused by a coronary anastomosis that is too narrow.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figures 1-3 The heating type carbon dioxide blowing tube shown includes a distal output tube 1, a gas delivery tube 2, and a liquid delivery tube 3; a handle 4 is sleeved on the distal output tube 1, and a heating structure 5 located outside the distal output tube 1 is provided inside the handle 4; one end of the gas delivery tube 2 is adapted to be connected to a carbon dioxide cylinder 6, and the other end extends into the distal output tube 1; one end of the liquid delivery tube 3 is adapted to be connected to a liquid storage bag 7, and the other end extends into the distal output tube 1.

[0034] This heated carbon dioxide blowpipe, with a heating structure 5 inside the handle 4, can heat the gas and liquid flowing through the distal output tube 1, reducing heat loss at the anastomosis site. This helps maintain the patient's core body temperature and heart rate, thereby improving surgical safety. At the same time, it can prevent the gas blown out of the blowpipe from being too cold, which could cause vasoconstriction and lead to other complications.

[0035] In this embodiment, a flow-closing clamp 9 is provided on the gas supply tube 2. This configuration allows the flow of carbon dioxide gas to be controlled by the flow-closing clamp 9, and the flow rate of carbon dioxide gas in the gas supply tube 2 can be adjusted by changing the degree of closure of the flow-closing clamp 9 to meet different needs during the operation. By completely closing the flow-closing clamp 9, backflow of carbon dioxide gas can be prevented, ensuring a stable gas environment in the surgical area and reducing complications during the operation.

[0036] In this embodiment, a gas filter 10 is provided on the gas supply pipe 2. This configuration allows the gas filter 10 to remove impurities and potential microbial contamination from the supplied carbon dioxide gas, thereby ensuring that the gas delivered to the surgical area is clean and safe, and reducing the risk of infection at the surgical site.

[0037] In this embodiment, an illumination element 11 is provided at the end of the distal output tube 1 furthest from the gas supply tube 2. This arrangement improves the illumination of the surgical anastomosis, solving the problem of insufficient brightness in the surgical field caused by a narrow coronary anastomosis. Specifically, a lighting switch suitable for controlling the illumination element 11 to be turned on and off is also provided on the handle 4.

[0038] In this embodiment, the heating structure 5 consists of a resistance wire 15 and a power source electrically connected to and adapted to provide energy to the resistance wire 15. This configuration, using the resistance wire 15 as the heating medium, leverages its ability to rapidly heat up and quickly respond to temperature changes, enabling the liquid and gas passing through the remote output tube 1 to heat up quickly, ensuring heating efficiency. Specifically, the resistance wire 15 can be any one of a nickel-chromium alloy, a tungsten-molybdenum alloy, or a copper-nickel alloy. Specifically, the power source is a button cell battery 13.

[0039] In this embodiment, a temperature control structure electrically connected to the heating structure 5 is also included. This configuration allows the temperature of the heating structure 5 to be adjusted and controlled via the temperature control structure, improving its ability to meet different needs during surgery and increasing surgical efficiency. Specifically, the temperature control structure includes a temperature sensor and a temperature controller electrically connected to the temperature sensor; the temperature sensor is adapted to sense the temperature of the heating structure 5 and feed the result back to the temperature controller; the temperature controller is adapted to adjust the power of the heating structure 5 after receiving the temperature value output by the temperature sensor, thereby controlling the temperature of the heating structure 5.

[0040] Specifically, the temperature control structure is adapted to maintain the temperature of the heating structure 5 at 37 degrees Celsius, enabling it to maintain a constant temperature. This configuration keeps the heating temperature of the heating structure 5 close to that of the human body, preventing the temperature of the gas blown out by the carbon dioxide blowpipe from being too high or too low. This reduces the overall temperature difference during surgery, which helps alleviate postoperative inflammation and promotes postoperative recovery.

[0041] In this embodiment, a flow regulator 8 is provided on the infusion tube 3. This configuration allows for precise adjustment of the fluid flow rate within the infusion tube 3 via the flow regulator 8. The flow rate can be adjusted according to different needs during the surgical procedure, facilitating more accurate surgical operations.

[0042] In this embodiment, the handle 4 includes a cylindrical outer shell 12, an infusion tube 3 and an air infusion tube 2 located at the center of the shell, a heating layer 14 surrounding the infusion tube 3 and the air infusion tube 2, and a power cord 17 located within the heating layer 14 and electrically connected to the lighting element 11. Specifically, a resistance wire 15 and a button battery 13 electrically connected to the resistance wire 15 are disposed within the heating layer 14; a channel 18 is disposed within the heating layer 14, and the power cord 17 is disposed within the channel 18 and electrically connected to the button battery 13; a switch button 16 is provided on the handle 4 to control the power supply to and from the button battery 13, and this switch button 16 can simultaneously control the heating start / stop of the resistance wire 15 and the lighting start / stop of the lighting element 11. In an alternative embodiment, two switch buttons 16 can also be provided to control the heating start / stop of the resistance wire 15 and the lighting start / stop of the lighting element 11 respectively.

[0043] In summary, this heated carbon dioxide blowpipe, by incorporating a heating structure 5 within the handle 4, can heat the gas and liquid flowing through the distal output tube 1, reducing heat loss at the anastomosis site. This helps maintain the patient's core body temperature and heart rate, thereby improving surgical safety. Simultaneously, it prevents the blowpipe from being too cold, which could lead to vasoconstriction and other complications.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
