Description

Technical Field

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

[0002] During arthroscopic surgery, traditional fluid filling methods are primarily used to maintain and expand the joint cavity, allowing surgeons to maintain a clear operating field of view. This method is particularly common during shoulder and hip arthroscopy, where tourniquets are not available to control bleeding. During surgery, bleeding can easily contaminate saline solution, leading to blurred vision and potentially compromising the smooth progress of the procedure. This situation presents a significant challenge for surgeons, especially novice surgeons, increasing both the difficulty and risk of the procedure.

[0003] In existing arthroscopic surgery, the medical system typically includes a fluid filling device, a pressure monitoring system, a drainage system, and an energy tool (such as a radiofrequency electrosurgical unit). The fluid filling device is used to inject saline solution into the joint cavity to expand the cavity, the pressure monitoring system monitors the pressure in the joint cavity in real time, the drainage system removes excess fluid and surgical debris, and the radiofrequency electrosurgical unit performs cutting and coagulation. However, this fluid filling method has several significant drawbacks: First, bleeding and tissue debris can easily contaminate the saline solution, obscuring the surgical field and compromising the accuracy of the procedure; second, fluid filling can easily cause tissue swelling, increasing postoperative recovery time; third, fluid leakage and unstable pressure increase the complexity and risk of the procedure, significantly impacting its effectiveness and safety. Furthermore, in PRP joint treatment, the fluid cavity prevents the drug powder from adhering, making this technique unsuitable for PRP. These factors pose varying degrees of limitations to articular cartilage repair surgery.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] Combine Figure 1 and Figure 2As shown, an embodiment of the present invention provides a carbon dioxide gas-assisted surgical operating system for arthroscopy, including a constant temperature gas circulation host 10, which has a built-in circulation pipeline. 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, which is used to penetrate the position of the arthroscope and introduce CO2 gas to establish a joint cavity.

[0039] The constant temperature gas circulation host 10 includes: a gas source component, a pressure stabilizing component, a circulating smoke removal component and a gas heating component. The gas source component is used to supply CO2 gas to the circulating pipeline; the pressure stabilizing component is used to 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 introduced into the arthroscope to 36~38℃.

[0040] 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 and exhaust gas in the joint cavity are recovered and filtered through the second pipeline 30 to maintain a clear surgical field of view. The gas heating component is used to heat the CO2 gas introduced into the arthroscope to 36~38℃ to prevent the lens from fogging, further improving the visibility and accuracy of the operation.

[0041] Among them, since this technical solution establishes a gas joint cavity through CO2 gas, the internal space of the joint cavity is dry, which is completely suitable for the attachment and effect of PRP technology powder, which has a very positive effect on articular cartilage repair.

[0042] For this solution, 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 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 and ankle joint, and even the spinal joint 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.

[0043] The working principle of the present invention is as follows: it 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, forming 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 a clear surgical field of view; this system uses low-pressure heated carbon dioxide gas to establish and maintain the stability of the joint cavity, forming 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 enhancing the safety of the operation.

[0044] 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.

[0045] It should be noted that the constant temperature gas circulation main unit 10 is also equipped with a third pipeline 60. One end of this third pipeline 60 is connected to the joint cavity via the puncture catheter 40, and the other end is equipped with an air pressure sensor. The air pressure sensor measures the air pressure data within the joint cavity in real time through the third pipeline 60, ensuring that the system can accurately monitor and regulate internal pressure. The diameter of the third pipeline 60 is designed to be much smaller than the diameters of the first pipeline 20 and the second pipeline 30. This design helps to avoid the phenomenon of pressure division in the pressure measuring pipeline, thereby ensuring the accuracy of air pressure measurement and the stability of air pressure within the joint cavity.

[0046] In this embodiment, an operating sheath 50 is provided 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.

[0047] It should be noted that the operating sheath 50 is designed to provide a stable access channel for the arthroscope, enabling smooth insertion into the joint cavity. The operating sheath 50 allows the surgeon to more precisely manipulate the arthroscope, reducing friction and damage between the arthroscope and tissue during surgery. Furthermore, the operating sheath 50 prevents gas leakage to a certain extent, further ensuring stable air pressure within the joint cavity. This design not only improves the convenience of the surgical procedure but also enhances its safety and effectiveness.

[0048] In this embodiment, it is further explained that the constant temperature gas circulation host 10 also includes a filter tube group 11, which 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.

[0049] This filtration step ensures the purity of the carbon dioxide gas entering the joint cavity, preventing impurities or particles from entering the surgical area, thereby protecting the patient's safety. The installation of filter tube assembly 11 not only improves gas quality but also reduces the risk of infection, further optimizing the surgical environment. Through this multi-level filtration and control, the system provides a cleaner and safer operating environment, significantly enhancing the overall effectiveness of surgery and the patient's postoperative recovery experience.

[0050] In this embodiment, it is specifically described that the circulating smoke removal component includes:

[0051] The smoke filter is provided on the second pipeline 30 and is used to filter particles and impurities in the smoke exhaust gas sucked away from the joint cavity through the second pipeline 30.

[0052] The suction pump is connected to the second pipeline 30 and is used 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, maintaining a clear surgical field of view.

[0053] The pressure regulating valve is located between the suction pump and the smoke filter. It is used to adjust the suction force to ensure that smoke and exhaust gases can be effectively sucked out without affecting the air pressure stability in the joint cavity. The pressure regulating valve can prevent excessive suction from causing unstable pressure in the joint cavity.

[0054] The exhaust pipe is connected to the outlet of the smoke filter to safely discharge the filtered exhaust gas into the surgical environment. The exhaust pipe ensures the cleanliness of the air in the operating room and reduces the impact of exhaust gas on surgical staff and patients.

[0055] In this embodiment, the gas heating assembly includes:

[0056] 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.

[0057] The temperature sensor is arranged in the circulation pipeline to detect the temperature of the CO2 gas and feed the temperature data back to the heating control unit so that the control module can adjust the heating power of the gas heating component.

[0058] 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 pressure stabilizing component. The control module is used to receive the air pressure data measured by the air pressure sensor and adjust the pressure stabilizing component according to the air pressure data to maintain the pressure in the joint cavity stable at 20~3010~30mlmmhg.

[0059] It's important to note that the control module is connected to the air pressure sensor and the pressure stabilization component. Its primary function is to receive pressure data from the sensor and adjust the pressure stabilization component in real time to maintain a stable pressure within the joint cavity between 20 and 30 ml / mmHg. Through a precise feedback mechanism, the control module ensures that joint cavity pressure remains within a safe range during surgery, thereby preventing surgical errors or complications caused by pressure fluctuations.

[0060] 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 and CO2 gas temperature data in the joint cavity in real time so that the surgical operator can monitor and adjust.

[0061] It should be noted that the display screen 12 is connected to the control module and is used to display real-time air pressure data and CO2 gas temperature data within the joint cavity. This real-time data display allows the surgical operator to monitor the status of the surgical environment at all times 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 appropriate adjustments, thereby improving the accuracy and safety of the surgery. Furthermore, the display screen 12 can record and store key data during the surgery, providing important reference for postoperative analysis and future surgeries.

[0062] In this embodiment, a connecting assembly 90 is also provided at one end of the puncture catheter 40 corresponding to the first pipeline 20. The connecting assembly 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, which is connected to a cleaning assembly 80 through the one-way valve 70. The cleaning assembly 80 is used to supply cleaning liquid to the joint cavity.

[0063] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can 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.
