Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a carbon dioxide gas-assisted surgical operation system for arthroscopy. Background Art

[0002] In arthroscopic surgery, the traditional liquid filling method is mainly used to maintain and expand the joint cavity so that the surgeon can obtain a clear operating field of view. This method is particularly common in shoulder and hip arthroscopy, because there is no tourniquet to stop bleeding in these areas, and the bleeding during the operation is prone to contamination of saline solution, resulting in blurred vision, which in turn affects the smooth progress of the operation. This situation is a huge challenge for surgeons, especially beginners, and increases the difficulty and risk of the operation.

[0003] In the prior art, the medical system of arthroscopic surgery usually includes a liquid filling device, a pressure monitoring system, a drainage system and an energy tool (such as a radiofrequency knife electrosurgical knife, etc.). Among them, the liquid filling device is used to inject physiological saline into the joint cavity to expand the cavity, the pressure monitoring system is used to monitor the pressure in the joint cavity in real time, the drainage system is used to discharge excess liquid and debris generated during surgery, and the radiofrequency knife energy tool is used for cutting and coagulation. However, this liquid filling method has several obvious disadvantages: first, because bleeding and tissue debris can easily contaminate physiological saline, the surgical field is blurred, affecting the accuracy of the surgical operation; second, liquid filling can easily cause tissue swelling and increase postoperative recovery time; third, problems such as liquid leakage and unstable pressure increase the complexity and risk of the operation. These shortcomings greatly affect the effect and safety of the operation; furthermore, in the PRP joint treatment technology, since the liquid cavity will cause the powder to be unable to adhere, this technology is not suitable for PRP technology, which has caused varying degrees of restrictions on the articular cartilage repair surgery technology. 。

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] Combination Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a carbon dioxide gas-assisted surgical operating system for an arthroscopy, comprising a constant temperature gas circulation host 10, wherein the constant temperature gas circulation host 10 has a built-in circulation pipeline, and the constant temperature gas circulation host 10 is provided with a first pipeline 20 and a second pipeline 30 respectively connected to the circulation pipeline; wherein, one end of the first pipeline 20 and the second pipeline 30 are respectively provided with a puncture catheter 40, and the puncture catheter 40 is used to penetrate into the position of the arthroscope and introduce CO2 gas to establish a joint cavity.

[0023] The constant temperature gas circulation main unit 10 includes: an air source component, a voltage stabilizing component, a circulating smoke removal component and a gas heating component. The air source component is used to supply CO2 gas to the circulating pipeline; the voltage stabilizing component is used to stably maintain the pressure in the joint cavity at 20~3010~30mlmmhg; the circulating smoke removal component is arranged on the circulating pipeline, and is used to recover the smoke and waste gas in the joint cavity through the second pipeline 30; the gas heating component is arranged on the circulating pipeline, and is used to heat the CO2 gas passed into the arthroscope to 36~38℃.

[0024] It should be noted that the gas source component is used to supply CO2 gas to the circulation pipeline to ensure that the system has sufficient gas supply. The pressure stabilizing component is used to maintain the pressure in the joint cavity within the range of 20~3010~30mlmmhg to ensure the stability of the cavity during surgery. The circulating smoke removal component is arranged on the circulation pipeline, and the smoke exhaust gas in the joint cavity is recovered and filtered through the second pipeline 30 to keep the surgical field clear. The gas heating component is used to heat the CO2 gas introduced into the arthroscope to 36~38℃ to prevent the lens from fogging and further improve the visibility and accuracy of the operation.

[0025] Among them, since the technical solution is to establish a gas joint cavity through CO2 gas, the internal space of the joint cavity is dry, which is completely suitable for the adhesion and effect of PRP technology powder, which has a very positive effect on articular cartilage repair.

[0026] For this scheme, it is further explained that, combined with Figure 1 and Figure 2 The diagrams shown are schematic diagrams of the system layout for the shoulder joint and the knee joint, which are the two main uses. However, it should be noted that the operating system of this solution can also be applied to the hip joint, elbow joint, wrist joint, ankle joint, and even spinal joints according to different treatment needs. The functional principle is to establish an air gap space between the bones (joints) so that relevant surgical operations can be carried out.

[0027] The working principle of the present invention is as follows: the system is controlled and operated by a constant temperature gas circulation host 10. When the system is started, the gas source component first supplies CO2 gas to the circulation pipeline, and injects the CO2 gas heated to 38 degrees into the joint cavity through the first pipeline 20. With the help of the puncture catheter 40, the expansion of the joint cavity is established and maintained to form a small cavity support. The pressure stabilizing component continuously monitors and adjusts the pressure in the joint cavity to stabilize it within the range of 20~3010~30mlmmhg (preferably 15mmhg) to ensure the stability of the joint cavity; during the operation, the circulating smoke removal component recovers the smoke exhaust gas in the joint cavity through the second pipeline 30, discharges the blood foam and debris generated during the operation, and processes them through the smoke filter to ensure the clarity of the surgical field of view; the system establishes and maintains the stability of the joint cavity through low-pressure heated carbon dioxide gas to form a small cavity support, and discharges the blood foam and debris generated during the operation through the circulating smoke removal component, thereby effectively avoiding the problem of blurred surgical field of view caused by bleeding and floating debris, significantly improving the visibility and accuracy of the operation, and improving the safety of the operation.

[0028] In this embodiment, it is further explained that the constant temperature gas circulation host 10 is also provided with a third pipeline 60, one end of the third pipeline 60 is connected to the joint cavity through the puncture catheter 40, and the other end is provided with an air pressure sensor, which is used to measure the air pressure data in the joint cavity through the third pipeline 60; wherein, the diameter of the third pipeline 60 is much smaller than the diameters of the first pipeline 20 and the second pipeline 30.

[0029] It should be noted that the constant temperature gas circulation host 10 is also provided with a third pipeline 60, one end of which is connected to the joint cavity through the puncture catheter 40, and the other end is provided with an air pressure sensor. The air pressure sensor measures the air pressure data in the joint cavity in real time through the third pipeline 60 to ensure that the system can accurately monitor and adjust the internal pressure. The diameter of the third pipeline 60 is designed to be much smaller than the diameter of the first pipeline 20 and the second pipeline 30. Such a design helps to avoid the pressure division phenomenon of the pressure measuring pipeline, thereby ensuring the accuracy of air pressure measurement and the stability of air pressure in the joint cavity.

[0030] In this embodiment, an operating sheath 50 is disposed at one end of the puncture catheter 40 , and the operating sheath 50 is used to allow the arthroscope to penetrate into the joint cavity.

[0031] It should be noted that the design purpose of the operating sheath 50 is to provide a stable access channel for the arthroscope so that the arthroscope can be smoothly inserted into the joint cavity. Through the operating sheath 50, the surgeon can operate the arthroscope more accurately, reducing the friction and damage between the arthroscope and the tissue during the operation. In addition, the operating sheath 50 can also prevent gas leakage to a certain extent, further ensuring the stability of the air pressure in the joint cavity. This design not only improves the convenience of the operation, but also enhances the safety and effectiveness of the surgical process.

[0032] In this embodiment, it is further explained that the constant temperature gas circulation main unit 10 also includes a filter tube group 11, and the filter tube group 11 is arranged between the circulation pipeline and the first pipeline 20, and is used to filter the CO2 gas provided by the gas source component.

[0033] This filtering step is to ensure the purity of the carbon dioxide gas entering the joint cavity, prevent impurities or particles from entering the surgical area, and thus protect the safety of the patient. The setting of the filter tube group 11 not only improves the gas quality, but also reduces the possible risk of infection, further optimizing the surgical environment. Through this multi-level filtering and control, the system can provide a cleaner and safer operating environment, significantly improving the overall effect of the surgery and the patient's postoperative recovery experience.

[0034] In this embodiment, it is specifically described that the circulating smoke removal component includes: The smoke filter is arranged on the second pipeline 30 and is used to filter the particles and impurities in the smoke exhaust gas sucked away from the joint cavity through the second pipeline 30.

[0035] The suction pump is connected to the second pipeline 30 to provide suction to suck out smoke and waste gas in the joint cavity through the second pipeline 30 and send it to the smoke filter. The suction pump ensures that smoke and waste gas can be continuously and effectively removed to keep the surgical field clear.

[0036] The pressure regulating valve is set between the suction pump and the smoke filter to adjust the suction force to ensure that the smoke and exhaust gas can be effectively sucked out without affecting the stability of the air pressure in the joint cavity. The pressure regulating valve can prevent excessive suction from causing unstable pressure in the joint cavity.

[0037] The exhaust gas discharge pipe is connected to the outlet of the smoke filter to safely discharge the filtered exhaust gas from the surgical environment. The exhaust gas discharge pipe ensures the cleanliness of the air in the operating room and reduces the impact of exhaust gas on surgical staff and patients.

[0038] In this embodiment, the gas heating assembly includes: The heating control unit is electrically connected to the gas heating component and is used to control the heating power of the gas heating component.

[0039] The temperature sensor is arranged in the circulation pipeline to detect the temperature of the CO2 gas and feed back the temperature data to the heating control unit so that the control module can adjust the heating power of the gas heating component.

[0040] In this embodiment, the constant temperature gas circulation host 10 also includes a control module, which is connected to the air pressure sensor and the voltage stabilizing component. The control module is used to receive the air pressure data measured by the air pressure sensor and adjust the voltage stabilizing component according to the air pressure data to maintain the pressure in the joint cavity stable at 20~3010~30mlmmhg.

[0041] It should be noted that the control module is connected to the air pressure sensor and the voltage stabilizing component. Its main function is to receive the air pressure data measured by the air pressure sensor and adjust the voltage stabilizing component in real time according to the data to maintain the pressure in the joint cavity stable at 20~3010~30mlmmhg. The control module ensures that the pressure in the joint cavity is always within a safe range during the operation through a precise feedback mechanism, thereby avoiding surgical errors or complications caused by pressure fluctuations.

[0042] In this embodiment, it is further explained that the constant temperature gas circulation host 10 also includes a display screen 12, which is connected to the control module and is used to display the air pressure data in the joint cavity and the temperature data of the CO2 gas in real time to facilitate monitoring and adjustment by the surgical operator.

[0043] It should be noted that the display screen 12 is connected to the control module and is used to display the air pressure data in the joint cavity and the temperature data of the CO2 gas in real time. The display of these real-time data enables the surgical operator to monitor the state of the surgical environment at any time and make timely adjustments as needed. The display screen 12 provides an intuitive interface, allowing the surgical operator to quickly understand the current operating conditions and make corresponding adjustments, thereby improving the accuracy and safety of the operation. In addition, the display screen 12 can also record and store key data during the operation, providing an important reference for postoperative analysis and future operations.

[0044] In this embodiment, a connecting component 90 is also provided at one end of the puncture catheter 40 corresponding to the first pipeline 20. The connecting component 90 is provided with a first connecting port and a second connecting port. The first connecting port is connected to the first tube body; the second connecting port is provided with a one-way valve 70, and is connected to a cleaning component 80 through the one-way valve 70. The cleaning component 80 is used to supply cleaning liquid to the joint cavity.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
