[0044] 1 and 2 , FIG1 is a partial structural schematic diagram 1 of an exemplary embodiment of an electrocut / electrocoagulation medical handle in an embodiment of the present application, and FIG2 is a partial structural schematic diagram 2 of an exemplary embodiment of an electrocut / electrocoagulation medical handle in the present application.

[0045] In one embodiment of the present application, the electrocuting / electrocoagulating medical device comprises:

[0046] A medical handle 20 is provided with an electrical connector 30, which is electrically connected to the high-frequency generator and the medical knife respectively;

[0047] A high-frequency generator, which is used to generate a high-frequency current and transmit it to the electrical connector 30;

[0048] a receiving electrode electrically connected to a high-frequency generator;

[0049] When the medical cutter is mounted on the medical handle 20 , the current generated by the high-frequency generator is transmitted to the medical cutter, and the current is then coupled to the receiving electrode through the spatial magnetic field.

[0050] In one embodiment of the present application, a medical handle 20 is used to drive a medical knife. An electrical connector 30 is provided on the medical handle 20 and is electrically connected to a high-frequency generator and the medical knife, respectively. After the medical knife and the medical handle 20 are assembled, the current generated by the high-frequency generator is transmitted to the electrical connector 30, which then transmits it to the medical knife. The current passes through the target tissue surrounding the medical knife, is coupled back to the receiving electrode via a spatial magnetic field, and finally returns to the high-frequency generator via the receiving electrode. During this process, the current heats the target tissue in contact with the medical knife, enabling the medical knife to perform electrocoagulation, thereby promoting coagulation of the target tissue at the surgical site, reducing bleeding during and after surgery, and thereby lowering the incidence of postoperative hematomas and complications. Furthermore, the released current can also disrupt the integrity of the target tissue, thereby improving the puncture and cutting capabilities of the medical knife, making the surgical process faster, thereby improving surgical efficiency, reducing patient pain, and lowering surgical risks. The high-voltage current is coupled through the spatial magnetic field, which can be understood as returning to the receiving electrode through wireless propagation technology. The receiving electrode does not need to come into contact with the tissue, making it more convenient for the operator to use and enabling more flexible surgery. There is no need to attach electrode plates to the patient's skin surface, which reduces pre-operative preparations, improves surgical efficiency, and avoids the discomfort caused to the patient by the attached electrode plates.

[0051] In one embodiment, the electrical connector 30 may be a terminal post, a conductive metal sheet, or the like.

[0052] The receiving electrode can be provided on the medical handle 20 or on the power ground of the high-frequency generator, as shown in FIG3 and FIG4 .

[0053] In one embodiment, the medical handle 20 also includes a first receiving electrode 40. The first receiving electrode 40 serves as a receiving electrode. The current generated by the high-frequency generator is transmitted to the medical tool. The current is then coupled to the first receiving electrode 40 through the spatial magnetic field and transmitted to the high-frequency generator through the first receiving electrode 40.

[0054] 1 and 2 , in this embodiment, the first receiving electrode 40 is disposed on the medical handle 20 and is spaced apart from the electrical connector 30 . The first receiving electrode 40 and the electrical connector 30 are not conductive. The current released by the medical tool is coupled to the first receiving electrode 40 on the medical handle 20 through the spatial magnetic field, and then returns to the high-frequency generator through the first receiving electrode 40 . The distance over which the current is coupled through the magnetic field is short, which is easy to implement and consumes less energy. In some embodiments, the current frequency generated by the high-frequency generator is between about 500 kHz and about 20 MHz, for example, between 500 kHz and 20 MHz.

[0055] In one embodiment, the medical handle 20 further includes a first wire 50 , and the electrical connector 30 and the high-frequency generator are connected via the first wire 50 .

[0056] 1 , in this embodiment, the electrical connector 30 and the high-frequency generator are connected via a first conductive wire 50 , thereby ensuring the stability and reliability of the connection between the electrical connector 30 and the high-frequency generator.

[0057] In one embodiment, the medical handle 20 further includes a second wire 60 , and the first receiving electrode 40 and the high-frequency generator are connected via the second wire 60 .

[0058] 1 , in this embodiment, the first receiving electrode 40 and the high-frequency generator are connected via a second wire 60 , which ensures the stability and reliability of the connection between the first receiving electrode 40 and the high-frequency generator.

[0059] In one embodiment, the medical handle 20 further includes a cable 10 . The cable 10 is provided on the medical handle 20 and is used to supply power to the medical handle 20 .

[0060] In this embodiment, the medical handle 20 is provided with a cable 10, which is mainly used to realize power supply and communication of the driving components of the medical handle 20. In one embodiment, the cable 10 is connected to one end of the medical handle 20, and the first wire 50 and the second wire 60 are also arranged in the cable 10. The cable 10 is connected to the interior of the medical handle 20, thereby reducing the line structure of the medical handle 20, avoiding the problem of line entanglement, and making it convenient for the user to hold the medical handle 20 for surgical operations.

[0061] In one embodiment, the electrical connector 30 is disposed at an end of the medical handle 20 close to the cable 10 , and the first receiving electrode 40 is disposed at an end of the medical handle 20 away from the cable 10 .

[0062] In this embodiment, in order to prevent the cable 10 from interfering with the surgical operation, the blade of the medical tool and the cable 10 can be respectively located at the two ends of the medical handle 20, and the first receiving electrode 40 is set at the end of the medical handle 20 away from the cable 10, so that the first receiving electrode 40 is close to the medical tool, which is conducive to receiving the current released by the medical tool through the spatial magnetic field coupling, and the electrical connector 30 is set at the end of the medical handle 20 away from the cable 10, so that the distance between the electrical connector 30 and the first receiving electrode 40 can be relatively far, ensuring that the line from the high-frequency generator to the medical tool via the electrical connector 30 and the line from the first receiving electrode 40 to the high-frequency generator are independent of each other, avoiding mutual interference or short circuit.

[0063] In one embodiment, the first receiving electrode 40 is disposed on the inner cavity or outer shell of the medical handle 20 .

[0064] In this embodiment, the first receiving electrode 40 can be set in the inner cavity of the medical handle 20 to reduce the possibility of damage to the first receiving electrode 40 and protect the operator from harm by high voltage current. The first receiving electrode 40 can also be set on the outer shell of the medical handle 20, which is simpler to manufacture.

[0065] In one embodiment, the electrocuting / electrocoagulating medical device further includes a medical cutter, which is connected to the medical handle and electrically connected to the electrical connector 30 .

[0066] In this embodiment, the electrocut / electrocoagulation medical device also includes a medical knife. The specific type of the medical knife can be selected according to the type of surgery. The medical knife is electrically connected to the electrical connector 30, so that the medical knife can directly release high-frequency current. The structure is simple and easy to implement.

[0067] In one embodiment, the medical knife is provided with a release electrode, which is electrically connected to the electrical connector 30 .

[0068] In this embodiment, a release electrode is provided on the medical tool, and the medical tool releases high-frequency current through the release electrode. The high-frequency current is released near the release electrode without passing through the entire medical tool, which can reduce damage to the medical tool, extend the service life of the medical tool, and reduce the possibility of high-frequency current injuring the operator.

[0069] In one embodiment, the release electrode is provided on the blade head of the medical knife.

[0070] In this embodiment, the medical knife mainly uses the blade head for cutting, puncturing and other operations. Setting the release electrode on the blade head of the medical knife can fully utilize the characteristics of high-frequency current, significantly improve the cutting and puncturing capabilities of the blade head, and reduce the amount of bleeding during surgery.

[0071] In one embodiment, the medical handle 20 includes a drive assembly, which is used to drive a medical tool, so that the medical handle 20 can be used to efficiently and flexibly drive medical props. For example, the drive assembly can be a motor or a reducer or a combination of a motor and related components.

[0072] In one embodiment, the medical handle includes a handle body 21, which is provided with a receiving cavity, and the electrical connector is arranged in the receiving cavity of the handle body 21. The electrical connector 30 and the handle body 21 can be fixed by snapping or screwing, etc., which can effectively store and shield the electrical connector, prevent the electrical connector from being contaminated by pollutants or being touched by the user during operation, and reduce the possibility of abnormal situations.

[0073] In one embodiment, when the first receiving electrode 40 is disposed inside the receiving cavity, it can also prevent the first receiving electrode from being contaminated by pollutants or being touched by the user during operation, thereby reducing the possibility of abnormal situations. The first receiving electrode 40 and the handle body 21 can also be fixed by snapping or screwing, thereby improving the connection stability between the first receiving electrode 40 and the handle body 21.

[0074] In one embodiment, the handle body 21 is made of insulating material, which can be plastic or rubber. The handle body 21 made of insulating material does not conduct electricity. During the operation, if leakage occurs due to line damage or other reasons, it is easy to cause harm to the operator holding the medical handle 20. The handle body 21 is made of insulating material, which can better protect the operator and reduce the possibility of injury to the operator.

[0075] Taking the electro-cutting / electro-coagulation biopsy device as an example, the above-mentioned electro-cutting / electro-coagulation biopsy device is described in detail. The medical cutting tool is a biopsy needle, which is used to perform tissue biopsy sampling. The high-frequency current generated by the high-frequency generator is transmitted via a first wire 50 to an electrical connector 30. From there, it is transmitted to the biopsy needle, which is drivably connected to the medical handle 20. The high-frequency current is released from the biopsy needle into the tissue in contact with the biopsy needle, achieving the electro-cutting / electro-coagulation function. The high-frequency current is then coupled from the tissue to the receiving electrode via a spatial magnetic field. When the receiving electrode is the first receiving electrode 40 located on the medical handle 20, the high-frequency current is transmitted back to the high-frequency generator through the first receiving electrode 40. When the receiving electrode is located on the power ground of the high-frequency generator, the high-frequency current is returned to the high-frequency generator through the power ground of the high-frequency generator. This improves the cutting and puncturing capabilities of the biopsy needle, while reducing bleeding during biopsy sampling, which promotes postoperative healing after the biopsy sampling procedure.
