Description

Technical Field

[0001] This utility model specifically relates to a telescopic smoking high-frequency ablation electrode. Background Technology

[0002] High-frequency ablation surgical electrodes are high-frequency surgical instruments that replace mechanical scalpels to cut and coagulate lesions by connecting to a high-frequency electrosurgical device. They are widely used in open and laparoscopic surgeries.

[0003] However, the following problems exist when performing surgical procedures in clinical practice:

[0004] (1) When performing laparoscopic surgery, the electrocoagulation hooks used by clinicians are of fixed length and cannot be adjusted according to the depth of the surgical site. The operator needs to manually control the length of the inserted part, which is inconvenient to use.

[0005] (2) Currently, the existing high-frequency electrosurgical equipment can only control the output of electro-cutting or electrocoagulation energy through a foot switch. Before outputting, it is necessary to confirm whether the foot switch is effectively connected, whether it is pressed in place, and whether the cutting or coagulation foot switch is pressed. Therefore, there may be a risk of accidental stepping and output, which affects the efficiency of the operation and increases the operation time. In addition, for the operation that requires cutting and coagulation of tissues with multiple impedances, frequent power switching is required to achieve the purpose of minimizing tissue thermal damage and completing the operation. The operator needs to know the power of electro-cutting or electrocoagulation used during the operation and adjust the output power of the high-frequency electrosurgical equipment. The existing equipment requires the circulating nurse to help the operator confirm and adjust the parameters on the high-frequency electrosurgical equipment operation screen, which is inconvenient to use.

[0006] (3) For smoke or liquid (including blood and irrigation fluid) generated during the operation, smoke will affect the surgical field, and liquid adhering to the tissue cut surface will affect the operation. Generally, smoke and liquid are suctioned by the negative pressure suction device in the operating room. This process increases the use of instruments, which need to be repeatedly inserted and removed or assisted by an assistant through another operating channel to complete the liquid suction. In addition, the diameter of the end of the existing smoke tube is not adjustable and the opening size is small. It can perform liquid suction, but the smoke suction effect is poor.

[0007] Therefore, finding a suitable and easy-to-use high-frequency ablation surgical electrode to solve the aforementioned problems of existing ablation electrodes has become a focus of attention for many front-line researchers in this field.

[0008] Chinese patent CN202220654691.7, entitled "A Smoking-Retractable Ablation Electrode," describes a device comprising a handle, a conductive tube, a smoking tube, and an electrode blade mounted on the conductive tube. The conductive tube is a retractable structure, positioned axially on the handle. The conductive tube comprises a positioning section and a suspension section. The positioning section is located within the handle, and the suspension section is located in front of the positioning section and suspended within the handle. The smoking tube is movably inserted through the handle along its axial direction, with one end inside the handle and the other end extending from the front end of the handle. The smoking tube is sleeved outside the suspension section and can slide relative to the suspension section axially. A gap is formed between the smoking tube and the suspension section to allow smoke to circulate.

[0009] As shown in the attached figure of patent CN202220654691.7, this patent mainly uses a telescopic conductive tube to achieve telescopic movement, and uses a smoking tube set on the handle to attract smoke. It has the functions of length adjustment and smoking, but the opening diameter of the smoking tube cannot be adjusted, the smoking effect is poor, and the power adjustment is relatively troublesome and inconvenient to use. Utility Model Content

Detailed Implementation

[0035] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0036] like Figure 1 and 11 As shown, a telescopic smoking high-frequency ablation electrode includes a handle 1, an electrocoagulation hook assembly 2, an angle adjustment assembly 3, a telescopic assembly 4, a smoking tube 5, a control assembly 6, and a power adjustment assembly 7.

[0037] One end of the electrocoagulation hook assembly 2 is inserted into the handle 1. The angle adjustment assembly 3 is set inside the handle 1 and connected to the electrocoagulation hook assembly 2. The angle adjustment assembly 3 can controllably adjust the radial angle between the electrocoagulation hook assembly 2 and the handle 1.

[0038] The telescopic component 4 is located inside the grip handle 1 and connected to the electrocoagulation hook component 2. The depth of the electrocoagulation hook component 2 inside the grip handle 1 can be controlled and adjusted through the telescopic component 4, thereby adjusting the length of the electrocoagulation hook component 2, which facilitates surgical operations at different depths.

[0039] The smoking tube 5 passes through the handle 1 and is connected to the electrocoagulation hook assembly 2. The smoking tube 5 can attract the smoke generated during the ablation process and the flushing fluid and tissue fluid during the ablation process. The diameter of the suction head at the end of the smoking tube 5 is adjustable to improve the smoke attraction effect.

[0040] The main function of the control component 6 is to work with the power adjustment component 7 to adjust the ablation power, making it suitable for cutting and coagulating various types of tissues with different impedances, and it is easy to use.

[0041] like Figure 1 , 2 As shown in Figure 11, the main function of the grip handle 1 is to facilitate the operator's grip. At the same time, the grip handle 1 also serves as a carrier for the installation of various components. The grip handle 1 is made of plastic and consists of an upper cover 11 and a lower cover 15. The upper cover 11 and the lower cover 15 are connected by screws, and after the upper cover 11 and the lower cover 15 are combined, there is a cavity in the middle for the installation of various components.

[0042] To facilitate the installation of the power adjustment component 7, a rectangular groove is recessed in the arc-shaped surface of the top cover 11. This groove is named the functional platform 12, and the buttons in the power adjustment component 7 are installed on this functional platform 12.

[0043] To facilitate the installation of function key 72 in power adjustment component 7, three button mounting holes are provided at intervals on the surface of function platform 12, and function key 72 is installed in these button mounting holes.

[0044] To facilitate the installation of the adjusting slider 71 inside the power adjustment assembly 7, a rectangular slot is provided on the functional platform 12. This slot is named the slider mounting slot 14. The adjusting slider 71 is locked in the slider mounting slot 14 and slides freely along the slider mounting slot 14.

[0045] On the side of the top cover 11, corresponding to the sliding hole 14 of the slider, there is a power scale 19 that indicates the power level. The power scale 19 can indicate the power level when the slider 71 is adjusting.

[0046] To facilitate the installation of the display screen 73 in the power adjustment assembly 7, a rectangular display screen mounting slot is recessed at the rear end of the upper cover 11, and the display screen 73 is installed in this display screen mounting slot.

[0047] Angle adjustment component 3 is installed inside the grip handle 1 and near the front end of the grip handle 1. In order to facilitate the operation of angle adjustment component 3 and thus control the rotation of electrocoagulation hook component 2, a rectangular hole is provided at the front end of the upper cover 11. This hole is named operation hole 13. The first adjustment dial 32 inside the angle adjustment component 3 passes through the operation hole 13 and is exposed to the outside for easy operation by the user.

[0048] Definition: In this embodiment, the end of the handle 1 on which the electrocoagulation hook assembly 2 is installed is the front end, and the other end opposite to it is the rear end.

[0049] To facilitate the installation of the electrocoating hook assembly 2, a telescopic guide groove 16 is provided inside the lower cover 15 and protrudes out of the lower cover 15. The cross-section of the telescopic guide groove 16 is a semi-circular shape with an arc. The guide rod 21 in the electrocoating hook assembly 2 can be locked in the telescopic guide groove 16 and will not fall off. The guide rod 21 can slide along the telescopic guide groove 16 within the telescopic guide groove 16.

[0050] To avoid positional interference, a rectangular clearance hole 18 is provided on the telescopic guide groove 16 at the position corresponding to the worm gear inside the angle adjustment component 3. The clearance hole 18 facilitates the installation of the worm gear inside the angle adjustment component 3 and avoids positional interference.

[0051] A rectangular plate is integrally fixed to the side of the telescopic guide slide 16, and this plate is named rack guide plate 17. The rack in the gear rack mechanism 41 of the telescopic assembly 4 can be locked in the rack guide plate 17 and slide freely along the rack guide plate 17.

[0052] like Figure 1 , 3 As shown in Figure 11, the electrocoating hook assembly 2 includes a guide rod 21 and an electrocoating hook 22. The guide rod 21 is a hollow round tube made of plastic, and its main function is to install the electrocoating hook 22 and its accessories. One end of the electrocoating hook 22 is installed inside the guide rod 21.

[0053] To facilitate the adjustment of the angle and extension of the guide rod 21, the guide rod 21 is designed in a multi-segment manner, including a sliding segment 23, a bellows 24 and a fixed segment 27, wherein the bellows 24 is located between the sliding segment 23 and the fixed segment 27.

[0054] The cross-section of the sliding section 23 is a regular hexagon. One end of the sliding section 23 is fixedly connected to the end of the guide rod 21 that is inserted into the grip handle 1. The main function of the sliding section 23 is to facilitate the installation of the worm gear in the angle adjustment component 3. The worm gear is sleeved on the sliding section 23. When the guide rod 21 moves in extension and retraction, the worm gear in the angle adjustment component 3 and the sliding section 23 can slide against each other, ensuring normal extension and retraction without affecting the rotation of the guide rod 21.

[0055] At the end of the sliding section 23, a ring is integrally fixed with the sliding section 23. The outer diameter of the ring is the same as the outer diameter of the guide rod 21. A bearing mounting groove 26 is recessed in the ring. The bearing 44 in the telescopic assembly 4 is installed in the bearing mounting groove 26.

[0056] To facilitate the extension and retraction of the guide rod 21, a bellows 24 is fixed on the guide rod 21 at the sliding section 23. The bellows 24 is connected to the sliding section 23 with glue. When the guide rod 21 is extended, the bellows 24 is stretched by force, and when the guide rod 21 is retracted, the bellows 24 is compressed by force.

[0057] To fix one end of the guide rod 21 and prevent it from falling out of the telescopic guide groove 16, a circular tube is integrally fixed to the bellows 24. This circular tube is named the fixing section 27. The outer and inner diameters of the fixing section 27 are the same as those of the guide rod 21. The fixing section 27 is fixed in the telescopic guide groove 16 with glue. In this way, when the guide rod 21 extends or retracts, the fixing section 27 on the guide rod 21 remains stationary, while the other parts move.

[0058] The electrocoagulation hook 22 is an existing device. One end of the electrocoagulation hook 22 is inserted into the guide rod 21 and connected to the control component 6 through the power supply line 25.

[0059] like Figure 1 and 4 As shown, the angle control component 3 includes a worm gear mechanism 31 and a first adjusting dial 32. A regular hexagonal mounting hole is provided on the worm gear in the worm gear mechanism 31, and the worm gear is sleeved on the sliding section 23 in the guide rod 21 through the mounting hole.

[0060] A mounting shaft is connected to the worm in the worm gear mechanism 31. The mounting shaft is fixed inside the upper cover 11 by two "U"-shaped mounting seats fixed to the inner wall of the upper cover 11. A circular dial is fixed on the mounting shaft coaxially with the worm. This dial is named the first adjustment dial 32. A part of the first adjustment dial 32 passes through the operation hole 13 and protrudes outside the upper cover 11. The operator can move the first adjustment dial 32 to adjust the angle of the guide rod 21.

[0061] By utilizing the self-locking function of the worm gear mechanism 31, unplanned displacement of the guide rod 21 can be effectively avoided, ensuring stability during use and making it convenient to use.

[0062] like Figure 1 , 5 As shown in Figure 6, the telescopic assembly 4 includes a gear and rack mechanism 41 and a limiting mechanism 45. The main function of the gear and rack mechanism 41 is to control the movement of the guide rod 21 and realize the control of the extension and retraction of the guide rod 21. The function of the limiting mechanism 45 is to restrict the movement of the gear and rack mechanism 41, prevent the guide rod 21 from moving unplanned, and ensure the overall practical stability of the device.

[0063] The gear and rack mechanism 41 includes a gear and a rack. The rack is placed in a groove on the rack guide plate 17 in the lower cover 15. The gear meshes with the rack, and the gear is mounted on the upper cover 11 by a pin. In addition, in order to facilitate the control of the gear rotation, a dial is fixed on the pin. This dial is named the second adjustment dial 43. The second adjustment dial 43 is exposed outside the upper cover 11. Rotating the second adjustment dial 43 can drive the gear to rotate.

[0064] To facilitate the connection between the rack and the guide rod 21, a rectangular connecting rod 42 is integrally fixed to the front end of the rack. The other end of the connecting rod 42 is fixedly connected to the outer ring of the bearing 44. The bearing 44 is fitted into the bearing mounting groove 26 on the guide rod 21. When the second adjusting wheel 43 is rotated, it can drive the rack to move, and then drive the guide rod 21 to move along the telescopic guide groove 16 through the connecting rod 42 and the bearing 44, thereby realizing the control of the extension and retraction of the guide rod 21.

[0065] The limiting mechanism 45 includes a limiting wheel 46 and a limiting rod 48. The limiting wheel 46 is a circular wheel. The limiting wheel 46 is coaxially connected to the gear in the gear and rack mechanism 41 and rotates synchronously with each other. On the arc surface of the limiting wheel 46, a plurality of rectangular limiting grooves 47 are uniformly recessed perpendicular to the limiting wheel 46.

[0066] The limiting rod 48 is a plastic rod with a rectangular cross-section. The limiting rod 48 is hinged to the rack guide plate 17 through a hinge seat. The limiting rod 48 can rotate along the hinge. At one end of the limiting rod 48, a rectangular limiting block 49 protrudes outward perpendicular to the limiting rod 48. The limiting block 49 can cooperate with the limiting groove 47 to limit the position.

[0067] In order to ensure that the limiting block 49 and the limiting groove 47 are continuously engaged, a spring 410 is fixed on the opposite side of the limiting block 49 on the limiting rod 48. One end of the spring 410 abuts against the limiting rod 48, and the other end abuts against the rack guide plate 17, so that the limiting block 49 and the limiting groove 47 are continuously engaged, preventing the limiting wheel 46 from rotating.

[0068] To release the engagement between the limiting block 49 and the limiting groove 47, a rectangular unlocking rod 411 protrudes from the end of the limiting rod 48 away from the limiting block 49. The unlocking rod 411 passes through the lower cover 15 and protrudes from the outside of the lower cover 15. An unlocking button 412 is fitted at the end of the unlocking rod 411. Pressing the unlocking button 412 can drive the limiting rod 48 to rotate along the hinge, thereby releasing the engagement between the limiting block 49 and the limiting groove 47. At this time, the limiting wheel 46 can rotate, which can control the extension and retraction of the guide rod 21. After releasing the unlocking button 412, the limiting block 49 engages with the limiting wheel 46 under the action of the spring 410. At this time, the limiting wheel 46 cannot rotate.

[0069] like Figure 1 , 7 As shown in Figures 8, 9, and 10, the smoking tube 5 is a hollow plastic tube. A variable diameter smoking head 51 is provided at the end of the smoking tube 5. An air inlet tube 58 is provided inside the smoking tube 5, through which the diameter of the variable diameter smoking head 51 can be adjusted.

[0070] The variable diameter smoking head 51 includes a fixing ring 52, an unfolding piece 53, and a V-shaped contraction airbag 56. The fixing ring 52 is a circular plastic ring with the same diameter as the smoking tube 5. The fixing ring 52 is fixed to one end of the smoking tube 5. The unfolding piece 53 is an arc-shaped triangular piece. The unfolding piece 53 is connected to the fixing ring 52 by a flexible plastic sheet. The unfolding piece 53 can rotate relative to the fixing ring 52 along the flexible plastic sheet. Multiple unfolding pieces 53 are evenly arranged along the fixing ring 52. In this embodiment, six unfolding pieces are preferably arranged. The six unfolding pieces 53 are evenly distributed on the fixing ring 52. The V-shaped contraction airbag 56 is arranged between two spaced unfolding pieces 53.

[0071] To facilitate the installation of the V-shaped inflatable airbag 56, rectangular grooves are recessed perpendicular to the two sides of the unfolding plate 53. These grooves are called airbag fixing grooves 55. One side of the V-shaped inflatable airbag 56 can be fixed in the airbag fixing groove 55 with glue.

[0072] The V-shaped contraction airbag 56 is an airbag in the shape of a "V". Similar to an accordion cover, when the V-shaped contraction airbag 56 is inflated, it can be deployed, which in turn drives the deployment plate 53 to move, thereby expanding the opening of the variable diameter smoking head 51 and adjusting the diameter of the variable diameter smoking head 51.

[0073] The deployment of the variable diameter smoking head 51 is controlled by the inflation of the V-shaped contraction airbag 56. When the V-shaped contraction airbag 56 is not inflated, the variable diameter smoking head 51, composed of the V-shaped contraction airbag 56 and the deployment plate 53, is in the shape of a cylindrical tube, which allows for the suction of liquid. When the V-shaped contraction airbag 56 is inflated, the variable diameter smoking head 51, composed of the V-shaped contraction airbag 56 and the deployment plate 53, becomes conical, improving the smoke suction capacity.

[0074] To facilitate the inflation and deflation of the V-shaped contraction airbag 56, a circular air guide ring 54 is embedded in the fixing ring 52. Six circular air guide tubes 57 are connected to the air guide ring 54. The air guide tubes 57 are connected to the V-shaped contraction airbag 56 respectively. The air guide ring 54 is connected to the inflation tube 58 in the smoking tube 5. The inflation tube 58 extends out from the end of the smoking tube 5 and is fixed with an inflation port 59. Through the inflation port 59, the V-shaped contraction airbag 56 can be inflated and deflated using a syringe, thereby realizing the expansion control of the opening of the variable diameter smoking head 51.

[0075] like Figure 11 As shown, the control component 6 includes a main control board 61 and a power adjustment board 62. The power adjustment board 62 is connected to the main control board 61. The main function of the main control board 61 is to control the entire device. The main function of the power adjustment board 62 is to cooperate with the power adjustment component 7 to adjust the ablation power.

[0076] The main control board 61 is placed in the main control board mounting slot on the lower cover 15. The power adjustment board 62 is installed under the functional platform 12 of the upper cover 11 by screws. Furthermore, a power sliding adjustment area is provided on the power adjustment board 62. The adjustment slider 71 in the power adjustment component 7 slides in the power sliding adjustment area to achieve power adjustment. This adjustment method is existing technology and will not be described in detail here.

[0077] like Figure 1 , 2 As shown in Figure 11, the power adjustment assembly 7 includes an adjustment slider 71, a function key 72, and a display screen 73. The adjustment slider 71 is installed in the slider mounting hole 14 on the upper cover 11, the function key 72 is installed in the button mounting hole on the function platform 12, and the display screen 73 is installed in the display screen mounting slot on the upper cover 11 and connected to the main control board 61.

[0078] The main function of the adjusting slider 71 is to adjust the power level as needed. The main function of the function key 72 is to adjust several fixed and commonly used power levels by pressing the key. The main function of the display screen 73 is to display the current ablation power in real time for the operator's convenience.

[0079] In this embodiment, the power adjustment slider 71 and function key 72 are integrated on the handle 1, allowing the operator to adjust the power independently without the assistance of a circulating nurse. This makes it convenient to use. In addition, the display screen 73 allows for intuitive power adjustment, making the operation convenient and quick.

[0080] The usage process of this embodiment:

[0081] 1. Angle adjustment: When it is necessary to adjust the radial angle of the electrocoating hook 22, the first adjusting dial 32 can be turned to drive the worm in the worm gear mechanism 31 to rotate. The worm drives the worm wheel sleeved on the guide rod 21 to rotate, thereby adjusting the angle of the guide rod 21, and thus adjusting the angle of the electrocoating hook 22 fixed at the end of the guide rod 21.

[0082] 2. Length adjustment: When it is necessary to adjust the length of the guide rod 21, first press the unlock button 412 to release the limit wheel 46. At this time, the second adjustment dial 43 can be rotated. Under the action of the second adjustment dial 43, the gear in the gear and rack mechanism 41 drives the rack to move. The movement of the rack drives the guide rod 21 to move, thereby adjusting the length of the guide rod 21 extending out of the grip handle 1.

[0083] 3. Adjustment of the opening diameter of the cigarette butt: When smoke suction is required, the V-shaped contraction airbag 56 can be inflated through the inflation port 59 using a syringe. After the V-shaped contraction airbag 56 is inflated, it unfolds, which in turn drives the unfolding plate 53 to unfold. At this time, the opening of the variable diameter cigarette butt 51 becomes larger, improving the smoking effect. After smoking is finished, the air in the V-shaped contraction airbag 56 can be extracted through the inflation port 59 using a syringe. At this time, the V-shaped contraction airbag 56 contracts, which in turn drives the unfolding plate 53 to retract. Liquid suction can then be performed.
