Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0074] Referring to the accompanying drawings Figure 1 The present application provides a surgical electrode 1000, which comprises an electrode member 100, a steering member 200, a fixing member 400, a transmission assembly 300 and an actuating assembly 500. The electrode member 100 is hinged with the steering member 200 and the fixing member 400, so as to realize the rotation of the electrode member 100 in different directions. The transmission assembly 300 drives the electrode member 100 to move in different directions by operating the brake assembly.

[0075] Referring to the accompanying drawings Figures 2-5 The electrode member 100 is used to realize electrocision and electrocoagulation. The electrode member 100 is electrically connected with a host computer, so as to realize the energy supply of electrocision and electrocoagulation of the electrode member 100 by the host computer.

[0076] Further, one end of the electrode member 100 is hinged with one end of the steering member 200, so that the electrode member 100 can be hingedly rotated relative to the steering member 200, and the orientation rotation of the electrode member 100 is realized.

[0077] The other end of the fixing member 400 is hinged with the steering member 200. The hinge shaft of the fixing member 400 and the steering member 200 is a steering shaft 210. The hinge shaft of the hinged end of the electrode member 100 is arranged at an angle with the steering shaft 210, and the angle is denoted as α, 0°<α<180°. By arranging the hinge shaft of the electrode member 100 at an angle with the steering shaft 210, when the steering member 200 is hingedly rotated relative to the fixing member 400, the electrode member 100 is driven to rotate at an angle different from the hinge shaft of the electrode member 100 itself. Preferably, α is 90°, so that the electrode member 100 is rotated in two mutually perpendicular hinge shafts, and the rotation operation in different orientations is realized by the rotation cooperation.

[0078] The transmission assembly 300 is in transmission connection with the other end of the steering member 200 and the electrode member 100 respectively, and the transmission assembly 300 can drive the other end of the steering member 200 and the electrode member 100 to rotate around the corresponding hinge shafts respectively; the transmission assembly 300 drives the steering member 200 to rotate relative to the fixed member 400 and drives the electrode member 100 to rotate relative to the steering member 200, and through the corresponding hinge rotations of the steering member 200 and the electrode member 100 respectively, the electrode member 100 can be rotated in two axial directions relative to the fixed member 400.

[0079] The actuating assembly 500 is in transmission connection with the transmission assembly 300, and the actuating assembly 500 is manually operated by a user and is used to control the driving action of the transmission assembly 300; the user operates the actuating assembly 500 to control the transmission assembly 300, thereby realizing the activity effect of the electrode member 100 in different directions.

[0080] The surgical electrode 1000 has the above technical features, the two ends of the steering member 200 are hinged with the electrode member 100 and the fixed member 400, and the hinge shafts of the two ends are arranged at an included angle α, so that the electrode member 100 can be rotated in different directions by rotating relative to the steering member 200 and rotating the steering member 200 relative to the fixed member 400, so that the electrode member 100 can be hinged and rotated relative to the two hinge shafts at an included angle α, thereby realizing the rotation in different directions; through the transmission connection between the actuating assembly 500 and the transmission assembly 300, the user can control the different driving actions of the transmission assembly 300 by manually operating the actuating assembly 500, and the electrode member 100 can realize the rotation in different directions through the transmission assembly 300.

[0081] In this embodiment, the electrode member 100 includes a first electrode head 110 and a second electrode head 120, and the shearing function is realized by the mutual approach between the first electrode head 110 and the second electrode head 120, and the steering function of the electrode member 100 is realized by rotating to the same side.

[0082] The first electrode includes a first hinge end 111, and the second electrode includes a second hinge end 121; the hinge connection between the electrode member 100 and the steering member 200 is realized through the first hinge end 111 and the second hinge end 121.

[0083] Specifically, the first hinged end 111 and the second hinged end 121 are hinged with one end of the steering member 200, and the transmission assembly 300 is in transmission connection with the first electrode head 110 and the second electrode head 120; the transmission assembly 300 can drive the first electrode head 110 and the second electrode head 120 to hinge and rotate around the respective corresponding hinged shafts; preferably, the hinged shafts of the first hinged end 111 and the second hinged end 121 coincide, so that the first electrode and the second electrode can rotate towards the same side and perform the shearing action, and the adhesion of the first electrode and the second electrode is improved.

[0084] Since most of the existing operations need to continuously coagulate and shear small blood vessels or tissues in the patient's body, coagulation hemostasis is achieved by a bipolar coagulation tool, and shearing small blood vessels or tissues is achieved by a scissors tool. During the operation, especially when separating the area rich in blood vessels, coagulation hemostasis and shearing small blood vessels or tissues need to be frequently performed, so the bipolar coagulation tool and the scissors tool need to be frequently replaced, which not only causes the operator to be tired and prolongs the operation time, but also easily touches or even damages other important tissues of the patient due to the small operation field, which is not conducive to the smooth operation, and also increases the amount of bleeding, leading to an increase in the difficulty of the operation, and further increases the risk of the operation; therefore, by realizing the hinged relationship between the first electrode head 110 and the second electrode head 120, the coagulation function is satisfied, and the shearing function of the electrode member 100 is realized by approaching and moving away from each other, thereby reducing the risk of the operation.

[0085] Further, the transmission assembly 300 includes an electrode guide wheel 310, a steering guide wheel 320, and a traction line 330; the rotation of the electrode guide wheel 310 and the steering guide wheel 320 is driven by the traction line, thereby realizing the hinged rotation of the electrode member 100 and the steering member 200.

[0086] Specifically, the electrode guide wheel 310 includes a first electrode wheel 311 and a second electrode wheel 312, the first electrode wheel 311 is in transmission connection with the first hinged end 111, and the second electrode wheel 312 is in transmission connection with the second hinged end 121, the rotation direction of the first electrode wheel 311 is parallel to the hinged shaft of the first hinged end 111, and the rotation direction of the second electrode wheel 312 is parallel to the hinged shaft of the second hinged end 121; the hinged rotation of the first electrode head 110 around its hinged shaft is driven by the rotation of the first electrode wheel 311, and the hinged rotation of the second electrode head 120 around its hinged shaft is driven by the rotation of the second electrode wheel 312; wherein the transmission connection between the electrode guide wheel 310 and the electrode member 100 is realized by a pin fixing or a pasting mode, and the specific connection mode is not limited here.

[0087] The two sides of the steering member 200 are respectively connected with the first steering wheel 321 and the second steering wheel 322 in the axial position of the steering shaft 210, and the rotation axes of the first steering wheel 321 and the second steering wheel 322 are parallel to the axial direction of the steering shaft 210; when the first steering wheel 321 or the second steering wheel 322 rotates, the rotation of the steering member 520 around the steering shaft 210 can be realized.

[0088] Further, the steering guide wheel 320 includes the first steering wheel 321 and the second steering wheel 322, and the first steering wheel 321 and the second steering wheel 322 are both connected with the other end of the steering member 200; the steering member 200 realizes the hinged movement through the rotation of the first steering wheel 321 and the second steering wheel 322.

[0089] The traction line 330 includes the first line member 331 and the second line member 332, and the actuating assembly 500 is connected with the first line member 331 and the second line member 332 in transmission, and the actuating assembly 500 is used for controlling the driving action of the traction line 330; through the control of the actuating assembly 500 on the first line member 331 and the second line member 332, the transmission control of the electrode guide wheel 310 and the steering guide wheel 320 is realized.

[0090] Further, the first line member 331 is connected with the first electrode wheel 311 and the first steering wheel 321 in transmission, and the second line member 332 is connected with the second electrode wheel 312 and the second steering wheel 322 in transmission; through the control of the first line member 331 and the second line member 332 on the rotation of different electrode wheels and steering wheels, the control of different direction movements of the electrode member 100 is realized; it should be noted that the first line member 331 and the second line member 332 can drive the rotation of the wheel body through the friction force or drive the rotation of the wheel body through the fixed installation on the wheel body, and the specific transmission connection mode is not limited here.

[0091] Specifically, the first line member 331 includes the first line segment 331A and the second line segment 331B, and the first line segment 331A and the second line segment 331B are respectively arranged on the two sides of the first electrode wheel 311; and from the first electrode wheel 311, the first line segment 331A and the second line segment 331B are respectively arranged on the same side of the first steering wheel 321; through the pulling of the first line segment 331A and the second line segment 331B, the rotation of the first electrode wheel 311 in different directions can be realized, and through the driving of the first line segment 331A and the second line segment 331B at the same time, the rotation of the first steering wheel 321 can be driven; wherein the first line segment 331A and the second line segment 331B are an integrated line segment structure or a separate line segment structure.

[0092] And, the second wire member 332 includes a third line segment 332A and a fourth line segment 332B, the third line segment 332A and the fourth line segment 332B are respectively arranged to abut against two sides of the second electrode wheel 312; and from the second electrode wheel 312, the third line segment 332A and the fourth line segment 332B are respectively arranged to abut against the same side of the second steering wheel 322; the pulling of the second line segment 331B and the third line segment 332A can realize the rotation of the second electrode wheel 312 in different directions, the pulling of the second line segment 331B and the third line segment 332A at the same time can drive the rotation of the second steering wheel 322; wherein the second line segment 331B and the third line segment 332A are an integrated line segment structure or a separate line segment structure.

[0093] In this embodiment, refer to the accompanying drawings Figures 6-8, the transmission principle of the first wire member 331 to the second wire member 332 is: 1) when the first wire segment 331A and the second wire segment 331B are pulled simultaneously while the third wire segment 332A and the fourth wire segment 332B are released, the first steering wheel 321 and the second steering wheel 322 are driven to rotate in opposite directions, and the steering member 200 rotates around the steering shaft 210; when the operation is reversed (the third wire segment 332A and the fourth wire segment 332B are pulled simultaneously while the first wire segment 331A and the second wire segment 331B are released), the rotation direction of the steering member 200 is reversed; since the first wire segment 331A and the second wire segment 331B or the third wire segment 332A and the fourth wire segment 332B are pulled simultaneously, the first electrode wheel 311 and the second electrode wheel 312 are relatively stationary; 2) when the first wire segment 331A and the third wire segment 332A are pulled simultaneously while the second wire segment 331B and the fourth wire segment 332B are released, the first electrode head 110 and the second electrode head 120 are simultaneously rotated around their hinge shafts, and the electrode member 100 is rotated towards the same side; when the operation is reversed (the second wire segment 331B and the fourth wire segment 332B are pulled while the first wire segment 331A and the third wire segment 332A are released), the first electrode head 110 and the second electrode head 120 rotate around their hinge shafts in opposite directions, and the electrode member 100 rotates towards the other direction; since the first wire segment 331A and the third wire segment 332A or the second wire segment 331B and the fourth wire segment 332B are pulled simultaneously, the wire segments on the upper and lower sides of the steering shaft 210 are pulled simultaneously, so that the writing member does not rotate around the steering shaft 210 when pulled; 3) when the first wire segment 331A is pulled while the second wire segment 331B is released, the first electrode head 110 is rotated around its hinge. When the fourth wire segment 332B is pulled while the third wire segment 332A is released, the second electrode head 120 is rotated around its hinge. At this time, since the rotation directions of the first electrode head 110 and the second electrode head 120 are different, the first electrode head 110 and the second electrode head 120 can be rotated towards different directions, thereby performing opening and closing movements. When the first wire segment 331A and the fourth wire segment 332B are pulled, the steering member 200 is in a stationary state relative to the fixed member 400 since the wire segments are on both sides of the steering shaft 210.

[0094] Therefore, by controlling the first wire segment 331A, the second wire segment 331B, the third wire segment 332A, and the fourth wire segment 332B through the actuating assembly 500, the electrode member 100 can be expanded and cut off, and rotated in different directions relative to the fixed member 400.

[0095] Further, referring to the drawingsFigure 12 The actuating assembly 500 comprises a hinged member 510, a rotating member 520, and an operating handle 530. By operating the handle 530 to rotate relative to the hinge of the fixed member 400, different tensioning control of the first line segment 331A, the second line segment 331B, the third line segment 332A, and the fourth line segment 332B is achieved.

[0096] Specifically, one end of the hinged member 510 is hinged to the other end of the fixed member 400, and the hinge axis of the hinged member 510 and the fixed member 400 is the first actuating axis 521. The hinged member 510 can rotate about the first actuating axis 521.

[0097] One end of the rotating member 520 is hinged to the other end of the hinged member 510, and the hinge axis of the hinged member 510 and the rotating member 520 is the second actuating axis 522. The axial direction of the first actuating axis 521 is perpendicular to the axial direction of the second actuating axis 522. The rotating member 520 can rotate about the second actuating axis 522.

[0098] The operating handle 530 comprises a first handle 531 and a second handle 532. The first handle 531 and the second handle 532 can rotate relative to the fixed member 400 about the first actuating axis 521 and the second actuating axis 522.

The third line segment 332A and the fourth line segment 332B are both arranged on the same side of the first actuating axis 521, and the third line segment 332A and the fourth line segment 332B are both arranged on the same side of the second actuating axis 522. By controlling the rotation of the first line member 331 and the second line member 332 about the first actuating axis 521 and the second actuating axis 522, different actions of the electrode member 100 are controlled.

[0100] The first handle 531 is in transmission connection with the first line member 331, and the second handle 532 is in transmission connection with the second line member 332. The first handle 531 and the second handle 532 are used to control the first line member 331 and the second line member 332, respectively. By pulling in different directions, the turning and opening / closing actions of the electrode member 100 are operated.

[0101] Further, the first actuating axis 521 is perpendicular to the hinge axis of the first hinged end 111, and the second actuating axis 522 is parallel to the hinge axis of the first hinged end 111.

[0102] The first linear member 331 is away from the abutting side of the second linear member 332 on the abutting side of the second steering wheel 322; when the first linear member 331 and the second linear member 332 are loosened and stretched in different directions, the first steering wheel 321 and the second steering wheel 322 can rotate in the same direction.

[0103] The first linear member 331 is away from the abutting side of the second linear member 332 on the abutting side of the first actuating shaft 521; when the rotating member 520 rotates around the first actuating shaft 521, the first linear member 331 or the second linear member 332 can be prevented from rotating on the same side at the same time.

[0104] The first linear member 331 is away from the abutting side of the second linear member 332 on the abutting side of the second actuating shaft 522; when the operating handle 530 rotates around the second actuating shaft 522, the first linear member 331 or the second linear member 332 can be prevented from rotating on the same side at the same time.

[0105] Preferably, on the operating horizontal plane, the horizontal position of the third linear segment 332A and the fourth linear segment 332B on the first actuating shaft 521 is higher than the horizontal position of the first linear segment 331A and the second linear segment 331B on the first actuating shaft 521, which better realizes the corresponding linkage between the rotating member 520 and the electrode member 100.

[0106] In the embodiment, the first handle 531 and the second handle 532 are both pivoted to the rotating member 520, and the rotation axes of the first handle 531 and the second handle 532 are parallel to the axial direction of the second actuating shaft 522; so that the first handle 531 and the second handle 532 can rotate around their respective pivoting axes.

[0107] Further, the first handle 531 comprises a first pivoting shaft 531A pivoted to the rotating member 520, and the first linear segment 331A and the second linear segment 331B are respectively arranged on both sides of the axial direction of the first pivoting shaft 531A; the rotation of the first pivoting shaft 531A can drive the first linear segment 331A and the second linear segment 331B to perform transmission action; the rotation of the first linear segment 331A and the second linear segment 331B in different directions is driven by the rotation of the first pivoting shaft 531A.

[0108] The second handle 532 comprises a second pivoting shaft 532A pivoted to the rotating member 520, and the third linear segment 332A and the fourth linear segment 332B are respectively arranged on both sides of the axial direction of the second pivoting shaft 532A; the rotation of the second pivoting shaft 532A can drive the third linear segment 332A and the fourth linear segment 332B to perform transmission action; the rotation of the third linear segment 332A and the fourth linear segment 332B in different directions is driven by the rotation of the second pivoting shaft 532A.

[0109] Specifically, by operating the rotation of the first pivot shaft 531A and the second pivot shaft 532A, the rotation of the first wire member 331 and the second wire member 332 in different directions is driven, and the opening and closing operation and the rotation in different directions of the electrode member 100 are driven.

[0110] The first pivot shaft 531A and the second pivot shaft 532A are both sleeved with transmission gears 533, and the transmission gears 533 are meshed with each other; the first pivot shaft 531A and the second pivot shaft 532A are respectively located on both sides of the second actuating shaft 522, and the first pivot shaft 531A is located on the side away from the abutting side of the first wire member 331 and the second actuating shaft 522; when the first handle 531 rotates, the first pivot shaft 531A and the second pivot shaft 532A are meshed and driven through the transmission gears 533, the second handle 532 is driven to rotate through the meshing between the transmission gears 533, and then the first wire member 331 and the second wire member 332 are driven.

[0111] Further, the distance between the first line segment 331A and the axis of the second actuating shaft 522 is less than the distance between the second line segment 331B and the axis of the second actuating shaft 522, and the distance between the third line segment 332A and the axis of the second actuating shaft 522 is less than the distance between the fourth line segment 332B and the axis of the second actuating shaft 522. When the first pivot shaft 531A and the second pivot shaft 532A rotate towards the same side, due to the difference between the axial distances, when the first wire member 331 and the second wire member 332 rotate around the second actuating shaft 522, the strokes of the first line segment 331A and the second line segment 331B are different, and the strokes of the third line segment 332A and the fourth line segment 332B are different, realizing the hinged rotation of the electrode member 100 relative to the steering member 200; preferably, the distance from the first line segment 331A and the third line segment 332A to the second actuating shaft 522 is the same, and the distance from the second line segment 331B and the fourth line segment 332B to the second actuating shaft 522 is the same, ensuring that the distances are the same when the line segments are loose or tight, and maintaining the movement stability of the electrode member 100.

[0112] In this embodiment, the transmission principle of the actuating assembly 500 is as follows:

[0113] 1) Participate in the attachment Figure 13When the first handle 531 and the second handle 532 are held to rotate the rotating member 520 to rotate the hinged member 510 around the first actuating shaft 521, the actuating assembly 500 is hinged to rotate around the first actuating shaft 521; when the hinged member 510 rotates around the first actuating shaft 521, it is equivalent to simultaneously pull the first line segment 331A and the second line segment 331B or the third line segment 332A and the fourth line segment 332B, and correspondingly release the third line segment 332A and the fourth line segment 332B or the first line segment 331A and the second line segment 331B, so as to realize the corresponding control of the electrode member 100 rotating around the steering shaft 210 by rotating the actuating assembly 500, and the rotating direction of the electrode member 100 is the same as the rotating direction of the actuating assembly 500. When the first line segment 331A and the second line segment 331B or the third line segment 332A and the fourth line segment 332B are simultaneously pulled or released, since the first line 331 and the second line 332 are positioned on the operation handle 530, there is no relative movement between the first line segment 331A and the second line segment 331B or between the third line segment 332A and the fourth line segment 332B, and at this time the electrode member 100 will not rotate left and right or open and close.

[0114] 2) refer to the attached Figure 14 When the operation handle 530 is held to rotate the rotating member 520 relative to the hinged member 510 around the second actuating shaft 522, it is equivalent to rotating the operation handle 530 and the rotating member 520 around the second actuating shaft 522, and since the first handle 531 and the second handle 532 are engaged through the transmission gear 533, the first pivot shaft 531A and the second pivot shaft 532A are relatively fixed; therefore, when rotating around the second actuating shaft 522, the first pivot shaft 531A and the second pivot shaft 532A are relatively stationary and rotate around the second actuating shaft 522, and since the distances between the first line segment 331A and the second line segment 331B and the second actuating shaft 522 are different, and the distances between the third line segment 332A and the fourth line segment 332B and the second actuating shaft 522 are different, the first line segment 331A and the third line segment 332A or the second line segment 331B and the fourth line segment 332B are pulled in different directions, and the second line segment 331B and the fourth line segment 332B or the first line segment 331A and the third line segment 332A are correspondingly released, so that the electrode member 100 can rotate around its hinged shaft when rotating around the second actuating shaft 522, and the rotating directions are in a corresponding relationship. When the rotating member 520 rotates around the second actuating shaft 522, since the first line segment 331A and the third line segment 332A or the second line segment 331B and the fourth line segment 332B are simultaneously pulled, and since the pulled line segments are located on both sides of the first actuating shaft 521, i.e., the rotation of the electrode member 100 around its hinged shaft does not affect the rotation of the electrode member 100 around the steering shaft 210.

[0115] 3) refer to the attached Figure 15When the first handle 531 and the second handle 532 are operated to rotate the first pivot shaft 531A and the second pivot shaft 532A, the first pivot shaft 531A and the second pivot shaft 532A rotate in opposite directions due to the meshing of the transmission gear 533 between the first pivot shaft 531A and the second pivot shaft 532A, and the first handle 531 and the second handle 532 are in an open or closed state; when the first pivot shaft 531A and the second pivot shaft 532A rotate relative to each other, the first line segment 331A and the fourth line segment 332B or the second line segment 331B and the third line segment 332A are pulled, and the second line segment 331B and the third line segment 332A or the first line segment 331A and the fourth line segment 332B are released at the same time, so that the first electrode head 110 and the second electrode head 120 are opened and closed, and the opening and closing action is the same as the opening and closing state of the first handle 531 and the second handle 532.

[0116] Currently, surgical robots are also used in clinical practice. Although the surgical site of the surgical robot can be bent, the surgical site is connected to the whole surgical robot, and the main surgeon is far away from the patient during operation, so the operation needs to be performed on a separate controller, which is difficult to handle unexpected situations during surgery. The surgical robot has a complex surgical execution mechanism and a large system, and the technical level of the surgeon and other hardware facilities of the hospital have certain requirements, making it difficult for small and medium-sized hospitals to popularize. Further, the manufacturing cost and maintenance cost of the surgical robot are high, resulting in high surgical costs. And the surgical robot occupies a large area, which has high requirements for the site of the hospital. The surgical electrode 1000 of the embodiment only needs to be held by the doctor through a single hand when in use, and the opening and closing, bending and other controls of the electrode member 100 can be realized, which is simple and efficient. The doctor is located next to the patient during surgery, and can handle various situations in a timely manner to improve surgical safety
