DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] Please refer to Figures 1-7The utility model provides a kind of medium circulation cooling structure's multifunctional dissector, including electrode cable 1, the one end of electrode cable 1 is connected with cooling medium pipe 2, cooling medium pipe 2 is connected with external cooling equipment by connecting piece, the cooling medium pipe 2 is connected with external cooling equipment by special connecting piece, and closed loop medium circulation system is formed;Cooling medium pipe 2 is provided with shunt flange 3, for realizing the shunt and control of medium, ensure that cooling medium orderly flows in system.Cooling medium pipe 2 is provided with shunt flange 3;The other end of electrode cable 1 is connected with connector 10, and two movable handles 5 are connected on connector 10, and forceps leg 6 is connected on movable handle 5, and forceps tip 7 is connected on forceps leg 6;The inside of forceps leg 6 is provided with cavity, and the cavity is communicated with electrode cable 1 by two shunt pipes 4;Cooling circulation assembly 9 is arranged on movable handle 5, for generating circulating flow channel to flow back cooling of forceps leg 6 and simultaneously carries out controllable operation of flow rate.The end of movable handle 5 is connected with forceps leg 6 respectively, and the inside of forceps leg 6 is equipped with cavity structure, the cavity is communicated with the medium channel in the inside of electrode cable 1 by two shunt pipes 4, and the complete medium flow path from handle to forceps tip 7 is formed.The end of forceps leg 6 is connected with forceps tip 7, and it is the direct contact component of surgical operation, is made of high heat conduction alloy material, and is processed by polishing to enhance the anti-sticking performance;The inside cavity of forceps leg 6 and shunt pipe 4 jointly constitute medium circulation path, realize the continuous cooling medium delivery and backflow from external cooling equipment to forceps tip 7 area.Cooling circulation assembly 9 is arranged on movable handle 5, and the assembly includes flow member, adjusting member and filter member, for forming controllable circulating flow channel in the inside of forceps leg 6, realizes the active cooling of forceps leg 6 and forceps tip 7 area.

[0033] In the embodiment, the cooling circulation assembly 9 includes a flow member; the flow member includes a water jacket 901, one end of the water jacket 901 is connected with the forceps leg 6, the other end of the water jacket 901 is communicated with the shunt pipe 4, and the left side of the water jacket 901 is provided with an opening 906, and the water jacket 901 is communicated with the cooling cavity 903 through the opening 906. On the left side wall of the water jacket 901, one or more openings 906 are accurately provided, the size and position of the openings are calculated by fluid mechanics optimization, to ensure the uniformity and efficiency of the medium flow. Through the openings 906, the internal cavity of the water jacket 901 and the cooling cavity 903 provided in the inside of the forceps leg 6 are effectively communicated, so that the cooling medium flowing from the shunt pipe 4 can smoothly enter the water jacket 901, and then be distributed into the cooling cavity 903 through the openings 906. When the cooling medium flows through the water jacket 901, the flow channel structure designed inside the water jacket 901 can guide the medium to generate appropriate turbulence, to enhance the heat exchange efficiency with the inner wall of the forceps leg 6. At the same time, the wall thickness and material selection of the water jacket 901 are also carefully designed, to ensure sufficient structural strength and good heat conduction performance, so that the high temperature generated in the forceps tip 7 area can be quickly conducted to the cooling medium through the forceps leg 6.

[0034] Further, the hollow tube 904 is inserted into the inner part of the tweezer leg 6, the surface of the hollow tube 904 is located in the water jacket 901 and the water inlet 907 is formed on the surface of the hollow tube 904, the left end of the hollow tube 904 is provided with the water outlet 11 which is communicated with the cooling cavity 903 in the inner part of the tweezer leg 6, one of the branch pipes 4 is communicated with the water inlet 907 and the other branch pipe 4 is communicated with the water outlet cavity 16 formed in the water jacket 901. One or more water inlets 907 are formed on the surface of the hollow tube 904 in the inner part of the water jacket 901, the position and aperture of the water inlets 907 ensure that the cooling medium can enter the hollow tube 904 with the best flow and speed. The low temperature cooling medium delivered by the external cooling device through one of the branch pipes 4 is firstly injected into the cold water cavity 905 of the water jacket 901 to be preliminarily cooled and distributed, and then is collected through the water inlets 907 and flows into the inner channel of the hollow tube 904. The water outlet 11 is the key outlet for the cooling medium to flow out of the hollow tube 904 and enter the final heat exchange stage. The water outlet 11 is directly communicated with the annular cooling cavity 903 in the inner part of the tweezer leg 6 which surrounds the hollow tube 904. The low temperature cooling medium is delivered to the cold water cavity 905 of the water jacket 901 through one of the branch pipes 4 which functions as the "water inlet pipe", and then enters the inner part of the hollow tube 904 through the water inlets 907. The medium flows to the end of the tweezer leg 6 in the hollow tube 904 and preliminarily exchanges heat with the surrounding structure through the tube wall in the process. After the medium reaches the end, it is discharged from the hollow tube 904 through the water outlet 11 and enters the annular cooling cavity 903. At this time, the flow direction of the medium is changed and the medium flows back along the outer wall of the hollow tube 904 to the handle direction in the cooling cavity 903. The heated medium flows back to the area of the water jacket 901 in the cooling cavity 903 and enters the water outlet cavity 16 specially arranged in the inner part of the water jacket 901 through the special opening 906 of the water jacket 901. The heated medium is collected from the water outlet cavity 16, flows out through the other branch pipe 4 which functions as the "water outlet pipe" and returns to the external cooling device to be cooled, thereby completing a complete cycle.

[0035] Furthermore, the regulating component also includes an air-cooled component, which includes an impeller 14 rotatably connected inside the hollow tube 904 and located inside the return water chamber 16. The impeller 14 is connected to a bearing ring 15 via a connector, and fan blades are connected to the bearing ring 15. An air-cooled chamber is also provided inside the water jacket 901, and the fan blades are located inside the air-cooled chamber. A cold water chamber 905 is also provided inside the water jacket 901. After the cooling medium from the distributor pipe 4 enters the cold water chamber 905, it enters the hollow tube 904 through the inlet 907. A heat dissipation fin 902 is provided inside the air-cooled chamber, and the bottom of the heat dissipation fin 902 extends into the cold water chamber 905. An air outlet 13 and an air inlet 12 are respectively opened on the left and right sides of the water jacket 901. The power source of the air-cooled component is an impeller 14, which is ingeniously set inside the hollow tube 904 and its position is exactly on the path of the return water chamber 16. When the cooling medium, having completed heat exchange and increased in temperature, flows through the return water chamber 16 during the recirculation process, it impacts the impeller 14, using the residual kinetic energy of the recirculating medium to drive the impeller 14 to rotate. The impeller 14 is connected to the bearing ring 15 via a reliable connector, which may be a thin shaft or a coupling structure. This connection efficiently and with low loss transmits the rotational motion of the impeller 14 driven by the recirculating medium to the bearing ring 15, on which fan blades are directly connected. When the bearing ring 15 rotates, it drives the fan blades to rotate synchronously at high speed. Inside the water jacket 901, a dedicated independent air-cooling chamber is designed. The aforementioned fan blades are precisely positioned inside this air-cooling chamber, forming a built-in miniature fan. Under the rotation of the fan blades, forced airflow is generated within the air-cooling chamber. External cooling air is drawn in through the air inlet 12 on one side of the water jacket 901, flows through the air-cooling chamber, and is discharged from the air outlet 13 on the other side, carrying heat. This continuous airflow blows directly over the outer surface of the tweezers 6, achieving external convective heat dissipation. To significantly enhance the air cooling effect, heat dissipation fins 902 are also installed inside the air cooling chamber. The bottom of these heat dissipation fins 902 extends into the interior of the cold water chamber 905. This allows the heat dissipation fins 902 to directly and efficiently exchange heat with the lowest-temperature cooling medium that has just entered from the distribution pipe 4, thus maintaining themselves at a very low temperature. When the fan blades drive the airflow past these low-temperature heat dissipation fins 902, the airflow is pre-cooled, becoming low-temperature cold air, greatly enhancing its cooling capacity for the outer wall of the tweezers 6. Without additional electrical drive, the system effectively supplements the main cooling system by utilizing only the inherent kinetic energy of the return medium within the system. Through gas-liquid combined cooling, the extreme control of the instrument's working end temperature is ensured, fully demonstrating the ingenuity and efficiency of the design.

[0036] In addition, the cooling circulation assembly 9 also includes a filtration element, which includes a filter cartridge 909. A central shaft 910 is fixedly connected inside the filter cartridge 909. Multiple blades 911 are arranged on the central shaft 910 inside the filter cartridge 909. The filter cartridge 909 is rotatably connected to the inside of the connector 10. The connector 10 has a media flow channel 914 inside, and an upper outlet 913 is provided on the upper left side of the connector 10, which communicates with the inlet 908. A central shaft 910 is fixedly connected inside the filter cartridge 909, providing it with core support and a rotation reference. Multiple blades 911 arranged circumferentially or spirally are arranged on the central shaft 910 inside the filter cartridge 909. When the cooling medium flows through the filter cartridge, it impacts these blades 911, thereby generating a driving torque, enabling the entire filter cartridge 909 to rotate around the central shaft 910 in the internal cavity of the connector 10, becoming a "self-cleaning" dynamic filter. The filter cartridge 909 is housed inside the connector 10, which has a precision-machined media flow channel 914 that guides the cooling medium from the distributor 4 to the filter cartridge 909 for filtration. An upper outlet 913 is located on the upper left side of the connector 10. This outlet 913 is the outflow channel for the filtered clean medium and is connected to the inlet 908 on the front water jacket 901 via an external pipe, thus forming a complete clean flow path from "filtration" to "delivery to the cooling end." When the cooling medium carrying impurities flows through the filter cartridge 909, it is filtered and purified. Simultaneously, the kinetic energy of the flowing medium drives the blades 911 to rotate the filter cartridge 909 continuously and slowly. This rotational motion effectively prevents excessive accumulation of impurities at the same location on the filter screen, greatly extending the effective working time of the filter element and ensuring that the cooling medium flowing to the tip 7 remains clean, thereby maintaining the high efficiency and reliability of the entire closed-loop cooling system.

[0037] In addition, a movable gap 917 is directly provided between the filter cartridge 909 and the connector 10. A scraper 916 is installed within the movable gap 917, and the scraper 916 abuts against the filter cartridge 909. Multiple partitions 915 are provided inside the filter cartridge 909, dividing the interior of the filter cartridge 909 into four flow chambers. Two diverter pipes 4 are provided on each of the two movable handles 5; one diverter pipe is for the medium inlet, and the other is for the medium outlet. The four diverter pipes 4 are connected to the four flow chambers respectively. This gap not only provides the necessary movement space for the continuous rotation of the filter cartridge 909 but also constitutes an important channel for impurity collection and discharge. At least one scraper 916 is fixedly installed within this movable gap 917. This scraper 916 is typically made of a flexible, wear-resistant material such as medical rubber or special engineering plastics, and its working edge maintains a constant elastic contact with the outer surface of the filter cartridge 909 after installation. When the filter cartridge 909 rotates under the drive of the cooling medium, impurities attached to its outer surface are scraped off in real time by the fixed scraper 916. The scraped-off impurities, under the influence of gravity and the medium flow, settle downwards through the movable gap 917 and are eventually collected in the receiving cavity of the bottom sleeve 912, thus achieving an automatic cleaning function without interrupting the procedure. To further optimize flow channel management and achieve independent and precise temperature control of the dual forceps legs 6, the interior of the filter cartridge 909 is divided into four independent fan-shaped flow chambers by multiple radially distributed partitions 915. This structure precisely corresponds to the piping system: each of the two movable handles 5 is equipped with two diversion pipes 4. For each handle, one diversion pipe 4 serves as the medium inlet pipe, and the other as the medium outlet pipe. The ends of these four diversion pipes 4 are respectively connected to the four flow chambers inside the filter cartridge 909. The medium from the external cooling device enters through two diagonal flow chambers of the filter cartridge 909 and flows to the two forceps 6 for cooling. After heat exchange, the return medium merges from the other two diagonal flow chambers and returns to the external cooling device. This "four-chamber isolation" design essentially creates two completely independent and non-interfering closed-loop cooling circuits for the two forceps 6, ensuring balanced and stable cooling efficiency of the bipolar system during operation and avoiding cross-influence between hot and cold media at the confluence point. This provides crucial thermal management consistency for delicate surgery.

[0038] It is worth noting that a sleeve 912 is inserted into the bottom of the connector 10, and the sleeve 912 has an internal receiving cavity that communicates with the movable gap 917. A protective rubber sleeve 8 is fitted over the surface of the electrode cable 1, a guiding overlap structure is provided between the two movable handles 5, and an insulating and anti-adhesive layer is provided on the outer layer of the forceps legs 6. By covering the surface of the electrode cable 1 with the protective rubber sleeve 8, insulation and operational comfort are enhanced; the guiding overlap structure between the movable handles 5 ensures the synchronization and stability of the movement of the two handles; and the insulating and anti-adhesive layer covering the outer layer of the forceps legs 6 further improves surgical safety and instrument durability.

[0039] Working principle: First, the cooling medium in the circulating cooling medium pipe 2 is connected to the external cooling equipment through the inlet / outlet media distribution flange 3. When the multi-functional dissecter is working, it generates a certain high temperature. At this time, the external cooling equipment will inject the cooling medium from the cooling medium pipe 2 through the distribution flange 3, and then enter the interior of the connector 10. The media flow channel 914 is provided with four channels, corresponding to four distribution pipes 4. Two of the distribution pipes 4 are for inlet flow and two are for outlet flow, corresponding to the circulation channels on the two movable handles 5. After the cooling medium enters through the two distribution pipes 4, it will pass through the filter cartridge 909 and flow through the filter cartridge 909. When the medium enters the filter cartridge 909, it will drive the blades 911 to rotate. Driven by the flow force, the entire filter cartridge 909 will rotate, avoiding clogging caused by the fixed position of one side of the filter cartridge 909. The rotation of the filter cartridge 909 will control the contact between its surface and the scraper 916, so the impurities will be scraped off by the scraper 916 and sink into the inside of the sleeve 912 by gravity. The operator can then pull out the sleeve 912 to empty the accumulated impurities. The medium will then pass through the filter cartridge 909 again, entering the interior of the water jacket 901 from the upper outlet 913, and then into the cold water chamber 905. It will then flow into the hollow tube 904 through the inlet 907, and then be discharged from the return outlet 11. It will enter the internal cavity of the tweezers 6, and from the bottom space of the tweezers 6, it will rise along the cooling chamber 903, and then enter the return water chamber 16 inside the water jacket 901 through the opening 906. After that, it will flow back to the interior of the filter cartridge 909 through another branch pipe 4, and finally flow back to the external cooling equipment through the branch pipe 4, realizing an effective return operation. By using the circulating return operation, the high temperature generated on the tweezers 6 can be effectively and evenly removed, achieving a high-efficiency cooling effect. During the water return process, the cooling medium flows from the return water chamber 16, which drives the impeller 14 to rotate. The rotation of the impeller 14 drives the bearing ring 15 to rotate through the connecting parts, which in turn drives the fan blades on the bearing ring 15 to rotate, generating negative pressure suction. Then, the airflow enters the air-cooling chamber from the air inlet 12 and then exits from the air outlet 13, thus generating airflow to cool the surface of the tweezers 6. The purpose of the heat dissipation plate 902 is to provide external cooling for the airflow. At this time, the heat dissipation plate 902 extends to the cold water chamber 905. The cooling medium is initially at a low temperature. The low temperature is then conducted to the heat dissipation plate 902 and then radiated to the interior of the air-cooling chamber. Therefore, the airflow temperature inside the air-cooling chamber is also very low. Thus, the flow of cold air can effectively cool the surface of the tweezers 6. The water cooling circulation provides internal cooling, while the airflow provides external auxiliary cooling.
