In laparoscopic or deep tissue surgery, the angle of the electrocautery hook often needs to be adjusted to adapt to complex anatomical structures. Therefore, with the development of surgery, higher requirements are placed on the operational flexibility, precision and adaptability of high-frequency electrocautery hooks to the surgical environment.
[0003] In the prior art, the blade or electrode rod of the high-frequency electrosurgical knife mostly adopts a rigid structure or a simple bending mechanism. For example, the prior patent with publication number CN121101740A discloses a bending compensation device for a high-frequency electrosurgical knife, which realizes bending adjustment through inner and outer snake bone tubes and realizes blade rotation through a rotating component. However, this device only solves the problem of blade bending accuracy and does not involve surgical smoke treatment, which will affect the doctor's judgment of the lesion location, thereby prolonging the operation time and reducing the accuracy of the operation.
[0004] However, integrating a smoking function into a bendable surgical electric hook requires overcoming several technical challenges. First, what structure should be used to connect the bendable snake-like joint with the hollow electrode tube to achieve smoking during the bending process? Second, how should the smoking path between the hollow structure of the snake-like joint, the electrode tube, and the smoking tube be designed to ensure smooth smoke extraction? Third, how should the conductive path between the smoking tube, the electrode tube, the snake-like joint, and the blade be designed to ensure smooth current conduction while also allowing for bending and rotation of the entire conductive path?

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] Example
[0022] according to Figure 1 , Figure 2As shown, a bendable smoking snake-bone electric hook includes a handle assembly 1, an attraction conductive assembly 2, a bending assembly 3, an adjustment assembly 4, a blade assembly 5, and a power cord 6. The attraction conductive assembly 2 is disposed inside the handle assembly 1 and extends outward along the axial direction of the handle assembly 1. The extended part includes a push-pull inner tube 21 and an outer functional tube 22 sleeved on the push-pull inner tube 21. The end of the push-pull inner tube 21 is fixedly connected to the push-pull movable tube 23. The bending assembly 3 includes a first bending connecting block 31, a second bending connecting block 32, and a plurality of bending joints 33 disposed between the two connecting blocks. The bending assembly 3 is fixedly connected to the blade assembly 5 through the first bending connecting block 31 and fixedly connected to the extended end of the push-pull inner tube 21 through a push-pull piece 34. The adjustment assembly 4 includes a rotation adjustment member 41 and a bending adjustment member 42 disposed sequentially at the end of the handle assembly 1, which are used to control the rotation and bending of the blade assembly 5, respectively. A button 11 is provided on the handle assembly 1, and a control board 12 is disposed inside. The control board 12 is electrically connected to the power cord 6 and the attraction conductive assembly 2, respectively.
[0023] according to Figures 3-5 As shown, the suction conductive component 2 is sequentially arranged along its axial direction as a push-pull inner tube 21, an outer functional tube 22, a push-pull movable tube 23, an inner conductive tube 24, and a conductive mounting component 25; an outer conductive tube 26 is sleeved around the inner conductive tube 24 and the conductive mounting component 25, and the outer conductive tube 26 is fixedly installed inside the handle assembly 1; the hollow structures inside the blade assembly 5, the bending assembly 3, and the suction conductive component 2 are interconnected and ultimately connected to the suction pipe 7 at the tail end of the handle assembly 1 to form a smoke path; a fixing part 251 is provided inside the conductive mounting component 25 facing the inner conductive tube 24, and the inner conductive tube 24 is fixedly installed on the conductive mounting component 25 through the fixing part 251; an installation groove 252 is also provided on the outer wall of the conductive mounting component 25. An elastic conductive element 13 is provided on the control board 12; the outer diameter of the conductive mounting element 25 is smaller than the inner diameter of the outer conductive tube 26, so that the inner conductive tube 24 and the conductive mounting element 25 can slide inside the outer conductive tube 26; the elastic conductive element 13 includes annular mounting portions 131 at both ends and an elastic contact portion 132 protruding towards the inner wall of the outer conductive tube 26 in the middle. The elastic conductive element 13 is engaged in the mounting groove 252 through the annular mounting portions 131 at both ends and abuts against the inner wall of the outer conductive tube 26 through the elastic contact portion 132; a conductive sheet 14 is also fixedly connected to the control board 12 and abuts against the outer conductive tube 26. The current is conducted to the control board 12 through the power line 6 and to the attraction conductive component 2 through the conductive sheet 14 to realize the conduction of the current path.
[0024] The electric hook device forms a smoke extraction path through a series of components: a blade assembly 5, a bending assembly 3, a push-pull inner tube 21, a push-pull movable tube 23, an inner conductive tube 24, and a conductive mounting component 25. All these components are hollow in design, forming a smoke extraction cavity through the interconnection of the hollow structures. This cavity is ultimately connected to an external negative pressure suction device via a suction pipe 7, thus enabling the electric hook device to extract smoke. A rubber insulating sleeve 27 is also fitted onto the bending assembly 3 and the outer functional tube 22, ensuring that the bending assembly 3 can effectively extract smoke regardless of whether it is bent or straight, preventing leakage from the gaps in the bending joint 33. This allows for real-time extraction of smoke or tissue fluid during surgery, ensuring a clean surgical field and improving the safety and efficiency of the procedure. The electric hook device is connected to an external main unit via a power cord 6, and current flows through the power cord 6. The current is conducted to the control board 12, which conducts the current to the outer conductive tube 26 through the conductive sheet 14 fixedly connected to the end. Since the inner wall of the outer conductive tube 26 is elastically abutted by the elastic conductive element 13, the elastic conductive element 13 conducts the current on the outer conductive tube 26 to the conductive mounting part 25. Then the current passes through the inner conductive tube 24, the push-pull movable tube 23, the push-pull inner tube 21 and the bending component 3 in sequence and finally reaches the cutter head assembly 5, realizing the conduction of the current path. Since the outer diameter of the conductive mounting part 25 is smaller than the inner diameter of the outer conductive tube 26, the entire attraction conductive assembly 2 can slide inside the outer conductive tube 26. Through the structural design of the elastic contact part 132 of the elastic conductive element 13, the elastic conductive element 13 can always abut against the inner wall of the outer conductive tube 26 no matter how the attraction conductive assembly 2 moves, so as to achieve stable current conduction.
[0025] according to Figures 6-8 As shown, the first bending connecting block 31, the second bending connecting block 32, and the bending joint 33 are all hollow structures. The first bending connecting block 31 and the second bending connecting block 32 are symmetrically provided with two fixing grooves 351 and two positioning grooves 352 along the axial direction. The fixing grooves 351 and the positioning grooves 352 are perpendicular to each other in the cross-sectional direction. The push-pull plate 34 is set in one fixing groove 351, and a pre-tightening steel wire 353 is fixedly set in each of the two positioning grooves 352. The push-pull plate 34 and the pre-tightening steel wire 353 are set perpendicular to each other in the cross-sectional direction, so that when the push-pull plate 34 adjusts the bending joint 33, the two pre-tightening steel wires 353 can apply a certain pre-tightening force to several bending joints 33 between the two connecting blocks, thereby ensuring the stability of the bending process of the bending joint 33 under the action of the pre-tightening steel wires 353.
[0026] according to Figures 9-11As shown, one end of the push-pull plate 34 is fixedly connected to the fixing groove 351 of the first bending connecting block 31, and the other end is fixedly connected to the end of the push-pull inner tube 21. The bending assembly 3 is also provided with two pre-tightening steel wires 353, which are fixedly installed on two positioning grooves 352 on the first bending connecting block 31 and the second bending connecting block 32, connecting the two. Several bending joints 33 are arranged between the first bending connecting block 31 and the second bending connecting block 32. Two sets of push-pull mounting holes 331 and two sets of steel wire mounting holes 332 are provided on the bending joints 33 at positions corresponding to the fixing groove 351 and the positioning groove 352. The pre-tightening steel wires 353 pass through the steel wire mounting holes 33. In section 2, the push-pull plate 34 is inserted through and movably disposed in the push-pull mounting hole 331; several curved joints 33 have abutment parts 333 on the side near the push-pull plate 34, and each curved joint 33 abuts against each other through the abutment parts 333. A curved groove 334 is also provided on the side opposite to the abutment parts 333; one end of the outer functional tube 22 sleeved outside the push-pull inner tube 21 is fixedly connected to the rotating adjustment member 41, and the other end is fixedly connected to the second curved connecting block 32; a movable part 35 is provided between the push-pull inner tube 21 and the second curved connecting block 32, so that there is room for movement between the two. The push-pull inner tube 21 bends the curved joints 33 toward the curved groove 334 by moving and squeezing the push-pull plate 34.
[0027] The first bending connecting block 31 is fixedly connected to the cutter head assembly 5. The front end of the push-pull plate 34 is fixedly connected to the fixing groove 351 on the first bending connecting block 31, and its rear end is fixedly connected to the front end of the push-pull inner tube 21. The connection method can be welding or screw riveting, etc. The push-pull plate 34 passes through the fixing groove 351 on the second bending connecting block 32 and the push-pull mounting hole 331 on the bending joint 33 in sequence. During installation, the side of the bending joint 33 closest to the push-pull plate 34 is installed as the abutment part 333. Each bending joint 33 abuts against each other through the abutment part 333. The part opposite to the abutment part 333 is... One side has a bending groove 334, and the bending groove 334 between each bending joint 33 will form a certain gap; since the second bending connecting block 32 is fixedly installed on the outer functional tube 22, and the moving part 35 is provided between the push-pull inner tube 21 and the second bending connecting block 32 as a movement space, when the push-pull inner tube 21 moves toward one end of the cutter head assembly 5, it will drive the push-pull plate 34 to move at the same time. The tension generated by the compression of the push-pull plate 34 will force the bending joint 33 to bend toward the bending groove 334 with a gap, thereby realizing the bending of the bending assembly 3 and the bending of the cutter head assembly 5.
[0028] according to Figure 12 , Figure 13As shown, an adjustment mounting base 43 is threadedly connected to the working end of the handle assembly 1. The adjustment mounting base 43 includes a first mounting part 431 and a second mounting part 432. The rotating adjustment member 41 is rotatably mounted on the first mounting part 431, and the bending adjustment member 42 is rotatably mounted on the second mounting part 432. A T-shaped fixing member 411 is provided inside the rotating adjustment member 41, and the external functional tube 22 is fixedly mounted on the T-shaped fixing member 411. A limit groove 412 is also provided inside the rotating adjustment member 41 to abut against the protruding part of the T-shaped fixing member 411. Because the front end of the push-pull plate 34 and the bending assembly 3 The first bending connecting block 31 is fixedly connected, and the rear end is fixedly connected to the front end of the push-pull inner tube 21. The two ends of the outer functional tube 22 are respectively fixedly connected to the second bending connecting block 32 and the T-shaped fixing piece 411 of the bending assembly 3. Therefore, when the rotating adjustment piece 41 on the rotating handle assembly 1 is rotated, the limiting groove 412 inside the rotating adjustment piece 41 will drive the T-shaped fixing piece 411 and the outer functional tube 22 fixedly connected thereto to rotate together, thereby driving the bending assembly 3, the cutter head assembly 5, the push-pull piece 34 and the push-pull inner tube 21 to rotate synchronously, realizing the free rotation of the cutter head assembly 5 in the circumferential direction.
[0029] according to Figure 12 , Figure 13 As shown, the second mounting part 432 has a push-pull movable groove 433, and a T-shaped threaded part 421 is provided in the push-pull movable groove 433. The threaded part of the T-shaped threaded part 421 extends out of the push-pull movable groove 433 and is connected to the internal thread of the bending adjustment part 42. The T-shaped threaded part 421 is coaxially sleeved on the push-pull movable tube 23, and one end of it abuts against the protruding surface of the push-pull movable tube 23. The push-pull movable tube 23 is also provided with a bearing 231 and a threaded clamping part 232. The bearing 231 is clamped by the clamping part 232 and abuts against the other end of the T-shaped threaded part 421. The T-shaped threaded part 421 in the push-pull movable groove 433... 21 is connected to the internal thread of the external bending adjustment component 42 through the screw thread. Since the bearing 231 is provided on the push-pull movable tube 23, the friction force when the bending adjustment component 42 rotates and drives the T-shaped thread component 421 to rotate can be reduced. When the bending adjustment component 42 is rotated, the T-shaped thread component 421 is restricted by the two sides of the push-pull movable groove 433. The T-shaped thread component 421 will move back and forth inside the push-pull movable groove 433, thereby driving the push-pull inner tube 21 to move together. The movement of the push-pull inner tube 21 will drive the push-pull plate 34 fixed at the end to bend and adjust the bending component 3, and finally realize the bending of the cutter head component 5.
