[0032] Reference Figures 1 to 2 , shows a schematic structural diagram of an electric surgical dissector described in an embodiment of the present application, which may specifically include: a handle 10, a blade head 20 and a rotating member 30; one end of the rotating member 30 is connected to the handle 10, and the blade head 20 is connected to the other end of the rotating member 30, and the rotating member 30 drives the blade head 20 to rotate, so that the blade head 20 rotates relative to the handle 10.

[0033] In the embodiment of the present application, the rotating member 30 drives the cutter head 20 to rotate, and the rotation angle of the cutter head 20 can be adjusted, so that the position of the cutter head 20 can be changed according to the location of the lesion, so that the cutter head 20 can be adjusted at multiple angles, and the control accuracy and operation flexibility of the cutter head 20 are improved, so that the cutter head 20 can be free separated according to the needs of the operation, and the positioning is more accurate, which improves the efficiency of the operation and reduces the occurrence of postoperative complications. The problem that the flexibility of the straight head or right-angle head cutter head 20 is relatively limited when cutting and peeling tissues is avoided, and the convenience of surgical operation is improved.

[0034] Specifically, in the embodiment of the present application, the handle 10 can also be called a blade, which is used for medical personnel to hold. The blade head 20 is used to directly contact the lesion to cut and peel off the tissue. For example, the blade head 20 can be made of stainless steel and coated with insulating materials such as polyamide or ceramic on the surface. The electrosurgical dissector also includes a driving member, such as a motor, which is connected to the rotating member 30 to drive the rotation of the rotating member 30.

[0035] In the embodiment of the present application, for example, the electrosurgical dissector can be used in thoracic surgery under thoracoscopic surgery, and can also be used in laparoscopic surgery in general surgery, gynecological laparoscopic surgery, urological laparoscopic surgery, etc., and has a wide range of applications. The embodiment of the present application does not limit the specific application scenarios of the electrosurgical dissector.

[0036] Optionally, in the embodiment of the present application, the rotating member 30 includes a connecting portion 31 and a rotating portion 32;

[0037] The connecting portion 31 is connected to the knife handle 10, the rotating portion 32 is rotatably connected to the connecting portion 31, and the cutter head 20 is connected to one end of the rotating portion 32 away from the connecting portion 31. In this way, a relatively stable and reliable connection between the rotating member 30 and the knife handle 10 is achieved through the connecting portion 31, and a relatively stable and reliable connection between the rotating member 30 and the cutter head 20 is achieved through the rotating portion 32. The rotating portion 32 is rotatably connected to the connecting portion 31, so that the rotation of the rotating portion 32 drives the cutter head 20 to rotate.

[0038] For example, in an embodiment of the present application, the rotating part 32 may be provided with a rotating shaft, and the connecting part 31 may be provided with a rotating hole. The rotating shaft passes through the rotating hole, and the rotating shaft can rotate relative to the rotating hole, thereby realizing a rotating connection between the rotating part 32 and the connecting part 31.

[0039] In the embodiment of the present application, optionally, the electrosurgical dissector further includes a transmission tube 40 and an aspirator connection end 41; the transmission tube 40 is connected to the rotating member 30, and the transmission tube 40 is inserted into the knife handle 10, the aspirator connection end 41 is arranged at one end of the knife handle 10 away from the cutter head 20, and the aspirator connection end 41 is connected to the transmission tube 40. In actual application, the electrosurgical dissector will perform electrocautery on tissue cells, and during the electrocautery process, carbonization and vaporization cause the substances in the cells to diffuse in the form of fine particles, generating a large amount of smoke and dust particles, etc., which affect the surgical field under the microscope, are not conducive to surgical operations, and also cause great harm to the health of medical staff in the operating room. Therefore, the transmission tube 40 and the aspirator connection end 41 are provided, so that the smoke generated by electrocautery at the position of the cutter head 20 can be sucked out. Specifically, the aspirator connection end 41 can generate suction, so that the smoke is discharged from the electrosurgical dissector along the transmission tube 40. For example, in the embodiment of the present application, the suction device connection end 41 may be a negative pressure suction device connection end 41 , through which a relatively stable and reliable suction force is provided.

[0040] When the suction device connecting end 41 is used to suck out the smoke in the prior art, a separate incision needs to be opened near the lesion, which increases the patient's incision. However, the present application can directly suck out the smoke generated by electrocautery through the transmission tube 40 and the suction device connecting end 41, without increasing the patient's incision, thereby reducing the occurrence of postoperative complications.

[0041] In addition, blood or fluid accumulation may occur during the operation. Through the transmission tube 40 and the suction device connection end 41, the blood or fluid accumulation at the position of the blade 20 can be sucked and discharged in time, thereby improving the convenience of the operation, avoiding the impact of blood or fluid accumulation on the wound, and improving the success rate of the operation.

[0042] For example, in an embodiment of the present application, a suction port is provided on one side of the transmission tube 40 close to the cutter head 10, and the diameter of the suction port increases successively from the cutter head 10 to the handle 20. The channel at the suction port can also be inclined to serve as a transition for smoke or accumulated blood and fluid, thereby achieving a better suction effect.

[0043] Optionally, in the embodiment of the present application, the electrosurgical dissector further includes a suction tube 42; the suction tube 42 is connected to the end of the knife handle 10 away from the knife head 20, and the suction tube 42 is connected to the transmission tube 40, and the aspirator connection end 41 is connected to the end of the suction tube 42 away from the knife handle 10. In this way, the connection between the transmission tube 40 and the aspirator connection end 41 is realized through the suction tube 42, and because the suction tube 42 is connected to the transmission tube 40, the smoke or blood and fluid generated by the electrocautery can pass through the transmission tube 40 and be transmitted to the aspirator connection end 41 along the suction tube 42. In addition, the suction tube 42 can be made of a flexible material, such as rubber, so that the suction tube 42 can be bent according to actual needs, and also has good wear resistance.

[0044] In the embodiment of the present application, optionally, the switch valve 43 is arranged in the suction tube 42 to control the connection and disconnection between the transmission tube 40 and the suction tube 42. In this way, the switch valve 43 can be used to control the opening or closing of the suction function. Specifically, when the switch valve 43 is opened, the transmission tube 40 and the suction tube 42 are connected, and the smoke or blood and fluid accumulation generated by the electrocautery can be sucked through the transmission tube 40. When the switch valve 43 is closed, the transmission tube 40 and the suction tube 42 are disconnected, that is, the switch valve 43 forms a blockage between the transmission tube 40 and the suction tube 42, and the transmission tube 40 and the suction tube 42 cannot be connected. When there is no smoke or blood and fluid accumulation generated by the electrocautery, it is not necessary to suck them, and the suction function of the electrosurgical dissector is turned off. In this way, it is also avoided that the suction device connection end 41 is always in a suction state for the lesion when working, and the suction device connection end 41 needs to be taken out from the surgical operation hole in time when the suction is completed in the prior art, which greatly improves the convenience of the surgical operation and is conducive to shortening the operation time.

[0045] For example, in the embodiments of the present application, Figure 1 As shown, the switch valve 43 can be rotated so that the axial direction of the switch valve 43 is parallel to the axial direction of the suction tube 42, thereby achieving the connection between the transmission tube 40 and the suction tube 42. In addition, the switch valve 43 can be rotated so that the axial direction of the switch valve 43 is perpendicular to the axial direction of the suction tube 42, thereby achieving the blockage between the transmission tube 40 and the suction tube 42 and disconnecting the two.

[0046] The connection between.

[0047] Optionally, in the embodiment of the present application, the electrosurgical dissector further includes an insulating tube 50, one end of the insulating tube 50 is connected to the transmission tube 40, and the other end of the insulating tube 50 is connected to the rotating member 30. The insulating tube 50 is used to achieve an insulated connection between the transmission tube 40 and the rotating member 30, thereby avoiding affecting the cutter head 20 during operations such as electrocautery.

[0048] In the embodiment of the present application, optionally, the electrosurgical dissector further comprises an insulating layer, which is coated on the outer circumference of the transmission tube 40 and the insulating tube 50. In this way, the transmission tube 40 and the insulating tube 50 are wrapped by the insulating layer, which further improves the reliability of the insulating pad and improves the safety and reliability of the electrosurgical dissector.

[0049] Optionally, in the embodiment of the present application, the electrosurgical dissector further comprises a rotating switch 11, which is disposed on the knife handle 10 and is electrically connected to the rotating member 30; the rotating switch 11 drives the rotating member 30 to drive the knife head 20 to rotate, so that the knife head 20 rotates to a preset angle relative to the knife handle 10. In this way, the rotation of the rotating member 30 can be more accurately controlled by the rotating switch 11, and the convenience of operation is also improved.

[0050] For example, the rotation angle of the rotating member 30 can be controlled by setting the rotation angle of the driving rotating member 30 corresponding to a 30° rotation of the rotating switch member 11 to 90°, setting the rotation angle of the driving rotating member 30 corresponding to a 45° rotation of the rotating switch member 11 to 180°, setting the rotation angle of the driving rotating member 30 corresponding to a 90° rotation of the rotating switch member 11 to 315°, and so on. The specific type of the rotating switch member 11 and the specific control method of the rotating member 30 may not be limited in the embodiments of the present application.

[0051] In the embodiment of the present application, optionally, the preset angle includes any value between 45° and 315°. For example, the preset angle can be set to 45°, 90°, 145°, 180° or 315°, etc. When the preset angle is 90°, the electrosurgical dissector can be a right-angle head. When the preset angle is 180°, the electrosurgical dissector can be a straight head. It can adapt to various surgical operation needs and can be set according to the actual surgical procedure. The embodiment of the present application does not limit the specific setting value of the preset angle.

[0052] Optionally, in the embodiment of the present application, the electrosurgical dissector further includes a power connector 60, which is connected to the handle 10 and electrically connected to the rotating member 30. For example, the power connector 60 can be a power cord with a plug, which can be connected to an external power source to provide a relatively stable and reliable power source for the rotation of the rotating member 30.

[0053] In summary, the electrosurgical dissector described in the embodiments of the present application may at least have the following advantages:

[0054] In an embodiment of the present application, the electrosurgical dissector includes: a handle, a blade head, and a rotating member; one end of the rotating member is connected to the handle, and the blade head is connected to the other end of the rotating member, and the rotating member drives the blade head to rotate so that the blade head rotates relative to the handle.
