Description

Technical Field

[0001] The utility model relates to the technical field of electrosurgical instruments, and more particularly to a reusable bipolar electrocoagulation forceps. Background Art

[0002] Bipolar coagulation forceps is a commonly used hemostatic tool. The front end of the bipolar coagulation forceps is equipped with two clamp heads, which are connected to a power source respectively. When in use, the forceps are operated so that the two clamp heads come into contact with the wound. Under the action of high-frequency current, local high temperature is generated at the wound, heating the bleeding tissue to cause protein coagulation, and the blood vessel lumen becomes smaller or blocked to achieve the effect of hemostasis.

[0003] In related fields, bipolar coagulation forceps are usually disposable medical devices. With the development of equipment and related processes for cleaning, disinfection and sterilization of medical devices, bipolar coagulation forceps can meet corresponding reuse standards after cleaning, disinfection and sterilization.

[0004] However, the structure of common disposable bipolar coagulation forceps is not designed to be disassembled, cleaned, or replaced with consumable parts. If the disposable bipolar coagulation forceps are directly cleaned, disinfected, and sterilized, it is not possible to quickly disassemble the bipolar coagulation forceps, which is inefficient, and it is also impossible to thoroughly clean the forceps head, blades, and other structures, which is less safe. In addition, because the blades and the forceps rod are usually assembled into an integrated structure, the blades cannot be replaced quickly and conveniently. The above reasons make it difficult to reuse disposable bipolar coagulation forceps in related fields. Utility Model Content

[0047] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0048] This embodiment provides a bipolar coagulation forceps comprising a housing assembly 1, a rod assembly 2, a control assembly 4, and an actuator assembly 3. The control assembly 4 can be assembled from multiple components into an integrated modular assembly. The proximal end of the rod assembly 2 is inserted into the control assembly 4, and the actuator assembly 3 is disposed at the distal end of the rod assembly 2. The housing assembly 1 is used to enclose the control assembly 4, providing insulation and protection.

[0049] It should be noted that, in this embodiment, the proximal end of a component refers to the end of the component closer to the control assembly 4 or the housing assembly 1, and the distal end of a component refers to the end of the component further away from the control assembly 4 or the housing assembly 1. For example, the proximal end of the rod assembly 2 refers to the end of the rod assembly 2 closer to the control assembly 4, and the distal end of the rod assembly 2 refers to the end of the rod assembly 2 further away from the control assembly 4.

[0050] Reference Figures 1 to 19 The bipolar electrocoagulation forceps of this embodiment has a housing assembly 1 comprising a first housing 11 and a second housing 12, which can be detachably connected via a magnetic attraction assembly 13; a rod assembly 2 comprising a cutting mechanism 22, a clamp rod 21 and an outer rod 23, wherein the cutting mechanism 22, the clamp rod 21 and the outer rod 23 are nested and connected from the inside out to form an integral structure, the cutting mechanism 22 comprising a knife rod 222 and a cutting blade 221 disposed at the distal end of the knife rod 222, and the proximal end of the clamp rod 21 is exposed from the outer rod 23. The proximal end of the knife rod 222 is exposed from the proximal end of the clamp rod 21; the control component 4 may include an activation button 43, a bracket 41, and a clamp rod driving mechanism 42 and a knife rod driving mechanism 44 arranged on the bracket 41; the actuator component 3 is arranged at the distal end of the rod component 2, and includes two clamp heads that can approach / move away from each other, at least one of the two clamp heads is connected to the distal end of the clamp rod 21, and at least one of the two clamp heads is provided with a knife groove, and the distal end of the cutting blade 221 can be pushed along the knife groove.

[0051] Therefore, refer to Figure 1 In the bipolar coagulation forceps of this embodiment, the proximal end of the rod assembly 2 can be inserted into the bracket 41, so that the clamp rod driving mechanism 42 is transmission-connected with the portion of the clamp rod 21 exposed from the outer rod 23, and the knife rod driving mechanism 44 is transmission-connected with the portion of the knife rod 222 exposed from the clamp rod 21; the actuator assembly 3, the rod assembly 2, and the control assembly 4 can be assembled into one, and after the first shell 11 and the second shell 12 are connected, they at least partially cover the control assembly 4.

[0052] Compared with the existing disposable bipolar coagulation forceps, the reusable bipolar coagulation forceps of this embodiment has a shell component 1 that is detachably connected through a magnetic attraction component 13, a rod component 2 that is an integrated structure, an actuator component 3 that is arranged at the distal end of the rod component 2, and a clamp rod drive mechanism 42 and a knife rod drive mechanism 44 of a control component 4 that are arranged on a bracket 41. Therefore, after use, the bipolar coagulation forceps of the present invention can quickly disassemble the shell component 1 and remove the rod component 2 of the integrated structure from the bracket 41, so that it can be more convenient to replace the bipolar coagulation forceps. The easily contaminated pliers head and cutting blade 221 are cleaned, sterilized and disinfected; in addition, since in the utility model, the cutting mechanism 22, the pliers rod 21 and the outer rod 23 are nested and connected from the inside to the outside as an integrated structure, the pliers rod driving mechanism 42 is connected to the transmission part of the pliers rod 21 exposed from the outer rod 23, and the knife rod driving mechanism 44 is connected to the transmission part of the knife rod 222 exposed from the pliers rod 21. On the one hand, it is more convenient to insert the rod assembly 2 into the bracket 41, and on the other hand, the control of the knife rod 222 and the pliers rod 21 by the control assembly 4 is more stable and reliable.

[0053] As an embodiment of the housing assembly 1, refer to Figure 2 The bracket 41 includes a first side plate 411 and a second side plate 412. The first side plate 411 and the second side plate 412 can be fixedly connected by bolts, or connected by magnetic attraction, or connected by gluing. The clamp rod drive mechanism 42 and the knife rod drive mechanism 44 are both connected between the first side plate 411 and the second side plate 412.

[0054] Reference Figure 3 , the inner side of the first shell 11 may be provided with a first clamping structure 112, the first side plate 411 may be limitedly clamped with the first shell 11 through the first clamping structure 112, and the first shell 11 and the first side plate 411 may also be fixedly connected by bolts; Figure 4 The second side plate 412 can be positionally engaged with the second shell 12 through a second engaging structure, and the second shell 12 and the second side plate 412 can also be fixedly connected by bolts.

[0055] The first shell 11 is formed with a first notch 141 below the integrated structure, and the second shell 12 is formed with a second notch 142 below the integrated structure. When the first shell 11 and the second shell 12 are connected through the magnetic component 13, the first notch 141 and the second notch 142 are combined to form a finger buckle 14, which is used to facilitate the user to hold the bipolar coagulation forceps in certain surgical operations.

[0056] The magnetic attraction assembly 13 between the first shell 11 and the second shell 12 includes 1 to 7 magnetic buckle pairs, and the magnetic buckle pairs include a first magnetic buckle arranged on the inner side of the first shell 11 and a second magnetic buckle arranged on the inner side of the second shell 12. The first magnetic buckle and the second magnetic buckle cooperate to ensure that the first shell 11 and the second shell 12 are detachably connected.

[0057] The inner side of the first shell 11 is provided with a first mounting groove 111 for mounting the first magnetic buckle, and the inner side of the second shell 12 is provided with a second mounting groove for mounting the second magnetic buckle. The positions of the first mounting groove 111 and the second mounting groove correspond to each other, and the shapes of the first mounting groove 111 and the second mounting groove correspond to the shapes of the first and second magnetic buckles. In addition, the inner diameters of the first and second mounting grooves correspond to the outer diameters of the first and second magnetic buckles, so as to ensure that the first and second magnetic buckles can be firmly fixed in the first and second mounting grooves. As an optimization solution for this example, when installing the first and second magnetic buckles, an appropriate amount of adhesive can be placed in the first and second mounting grooves, or other reinforcement methods can be used.

[0058] As a further optimization, there are at least two magnetic buckle pairs, and the magnetic buckle pairs are divided into a first group of magnetic buckle pairs 131 and a second group of magnetic buckle pairs 132. The first group of magnetic buckle pairs 131 is arranged above the integrated structure, and the second group of magnetic buckle pairs 132 is arranged below the integrated structure. The first group of magnetic buckle pairs 131 and the second group of magnetic buckle pairs 132 can be evenly arranged along the edges of the first shell 11 and the second shell 12.

[0059] Furthermore, the second set of magnetic clasps includes at least two pairs of magnetic clasps, with at least one pair of magnetic clasps positioned between the finger clasp 14 and the integrated structure. By employing this technical solution, the magnetic clasps are evenly arranged along the edges where the first and second shells 11, 12 connect, ensuring both a detachable connection between the first and second shells 11, 12 and a stable and secure connection.

[0060] A first recess 151 is provided on the upper side surface of the first shell 11, and a second recess 152 is provided on the upper side surface of the second shell 12. The positions of the first recess 151 and the second recess 152 are corresponding to each other. When the first shell 11 and the second shell 12 are combined through the magnetic buckle, the first recess 151 and the second recess 152 are combined to form a quick-release groove 15. When removing the shell assembly 1, force can be applied through the quick-release groove 15 to improve the convenience of removal.

[0061] As an embodiment of the rod assembly 2, refer to Figure 5The rod assembly 2 includes a rotation control member 26, which is rotatably connected to the bracket 41 and is used to drive the rod assembly 2 to rotate relative to the bracket 41. The rotation control member 26 is mounted on the other end of the rod assembly 2 away from the actuator assembly 3, that is, the proximal end of the rod assembly 2 closer to the main body of the bipolar coagulation forceps. After the rod assembly 2 is rotatably connected to the main body of the bipolar coagulation forceps, the rotation control member 26 is used to drive the rod assembly 2 to rotate relative to the main body of the bipolar coagulation forceps to adjust the angle of the clamp.

[0062] Reference Figure 6 A quick-release mechanism 27 may be connected to the rotation control member 26 , and the quick-release mechanism 27 is used to realize the rapid disassembly and assembly of the rod assembly 2 and the main body of the bipolar coagulation forceps.

[0063] As an example, see Figure 7 The quick release mechanism 27 includes a trigger member 272 and a locking seat 271. The rod assembly 2 is at least partially inserted into the locking seat 271. The trigger member 272 can slide relative to the locking seat 271 so that the trigger member 272 has an unlocked state and a locked state. When the excitation member 272 is in a locked state, the rod assembly 2 is locked with the locking seat 271, and the rotary control member 26 can drive the rod assembly 2 to rotate. Since the rotary control member 26 is usually rotatably connected to the main body of the bipolar coagulation forceps, the rod assembly 2 and the actuator assembly 3 arranged at the distal end of the rod assembly 2 are rotatably connected to the main body of the bipolar coagulation forceps; when the excitation member 272 is in an unlocked state, the rod assembly 2 and the locking seat 271 are released from the locking seat 271, and the rod assembly 2 can be removed from the locking seat 271, while the rotary control member 26 is still connected to the main body of the bipolar coagulation forceps, that is, the rod assembly 2 and the actuator assembly 3 arranged at the distal end of the rod assembly 2 are removed from the main body of the bipolar coagulation forceps, thereby completing the rapid removal of the rod assembly 2 from the main body of the bipolar coagulation forceps.

[0064] By adopting the above-mentioned technical solution of this embodiment, the user can quickly and easily remove the rod assembly 2 and the actuator assembly 3 from the main body through the quick-release mechanism 27 for cleaning, disinfection, sterilization and other operations, ensuring the safety of the instrument during reuse, and reusable instruments also reduce the waste of medical resources and reduce medical costs.

[0065] As an example of how to stimulate, see Figure 9, a rod clamp quick release mechanism 27 of this embodiment may also include a button 261, which is protruding and embedded on the rotation control member 26, or serves as a part of the rotation control member 26, and the rotation control member 26 is in contact with the excitation member 272. The rotation control member 26 can be used to drive the excitation member 272 to slide relative to the locking seat 271, and the surface of the rotation control member 26 may be provided with anti-slip grooves, which increases the friction between the user and the rotation control member 26, further ensures the reliability of the process of rotationally controlling the actuator assembly 3 through the rotation control member 26, and facilitates the user to position during operation, further improving the convenience of the disassembly process.

[0066] Of course, as another example of the excitation method, an operating hole can be opened on the rotary control member 26 so that at least a portion of the excitation member 272 can be exposed from the rotary control member 26. The user can operate the excitation member 272 by pressing the portion of the excitation member 272 exposed from the rotary control member 26.

[0067] As an example of the excitation member 272, the excitation member 272 may include a contact portion 2721, a fixing portion 2723 and an excitation reset member 2722. When a button 261 is provided on the rotary control member 26, the contact portion 2721 may be in contact with and cooperate with the button 261. The fixing portion 2723 is locked and cooperated with the rod assembly 2 when the excitation member 272 is in a locked state, and is disengaged from the rod assembly 2 when the excitation member 272 is in an unlocked state. This locking cooperation may be a friction cooperation to achieve locking, or a shape cooperation to achieve locking, or a locking cooperation similar to a latch and a pin control, or any other cooperation method that can achieve locking to prevent the rod assembly 2 from moving along its axial direction relative to the locking seat 271. The excitation reset member 2722 is arranged on the contact portion 2721 to realize the reset of the excitation member 272. The excitation reset member 2722 can be a spring in the form of a compression spring, a tension spring, a torsion spring, etc. One leg of the spring cooperates with the excitation member 272, and the other leg of the spring cooperates with the locking seat 271 or the rotation control member 26. When force is applied to the excitation member 272 to put it in an unlocked state, the excitation reset member 2722 is deformed and has elastic potential energy. When the force is removed, the excitation reset member 2722 restores its deformation and drives the excitation member 272 to reset.

[0068] As an example of the locking seat 271, refer to Figure 8 A limiting groove 2711 that cooperates with the fixing portion 2723 is provided on the side of the locking seat 271, and a first channel 2712 for the rod assembly 2 to pass through is provided in the middle of the locking seat 271.

[0069] By adopting the above technical solution, during use, the user can press the button 261 provided on the rotation control member 26. The button 261 presses down to trigger the trigger member 272, causing the trigger member 272 to switch from the locked state to the unlocked state. At the same time, the fixing portion 2723 is disengaged from the rod assembly 2, enabling the rod assembly 2 to disengage from the first channel 2712 provided in the middle of the locking seat 271, achieving the disassembly of the rod assembly 2 quickly and simply.

[0070] As one example, referring to Figure 10 , the rod assembly 2 may include a tool bar 222, a pliers bar 21, an outer rod 23, a first insulating layer 24, and a second insulating layer 25 that can be sleeved into an integral structure. The tool bar 222 is arranged in the innermost layer, and a cutting blade 221 is provided at the end of the tool bar 222. A clamp is provided at the end of the pliers bar 21. A first insulating layer 24 is provided between the tool bar 222 and the pliers bar 21. The outer rod 23 is arranged in the outermost layer, and a second insulating layer 25 is provided between the outer rod 23 and the pliers bar 21. The materials of the first insulating layer 24 and the second insulating layer 25 can be resin, can be silicone rubber, can be PVC, or can be any other material that can achieve the same function.

[0071] In addition, at least one locking hole is provided on the outer rod 23, or multiple locking holes can also be provided. The locking holes are used for locking and cooperating with the fixing portion 2723.

[0072] As a further optimization, the fixing portion 2723 can be a C-shaped structure, or can be any other structure that can achieve the same function, such as a 冂-shaped structure, a V-shaped structure, etc. A fixing protrusion 2724 can be provided at the bottom end of the C-shaped structure. At least one locking hole corresponding to the position of the fixing protrusion 2724 can be opened on the lower side of the outer rod 23, or multiple fixing protrusions 2724 can be provided, and multiple locking holes corresponding to the positions of the multiple fixing protrusions 2724 are opened on the lower side of the outer rod 23. The outer rod 23 passes through the C-shaped structure, and the fixing protrusion 2724 is locked and cooperated with the locking hole. In addition, a limiting groove 2711 can be opened on the locking seat 271. The limiting groove 2711 is used to accommodate the C-shaped structure of the fixing portion 2723. When the rod assembly 2 attempts to move relative to the locking seat 271 along its axial direction in the locked state, the locking hole interferes with the fixing protrusion 2724, and the C-shaped structure abuts against the groove wall of the limiting groove 2711, preventing the fixing portion 2723 from breaking and causing damage to the rod pliers quick-release mechanism 27 of the present utility model.

[0073] By adopting the above technical solution, when the trigger member 272 is in the locked state, the rod assembly 2 can be firmly inserted into the first channel 2712 of the locking seat 271 through the cooperation of the fixing portion 2723 and the locking hole, ensuring the structural stability of the instrument.

[0074] As another embodiment of the rod assembly 2, refer to Figure 11 and 12 The rod assembly 2 includes a cutting mechanism 22, a clamp rod 21, and an outer rod 23. The cutting mechanism 22 is disposed within the clamp rod 21, and the outer rod 23 is sleeved on the clamp rod 21. The cutting mechanism 22, the clamp rod 21, and the outer rod 23 are sleeved sequentially from the inside out to form an integrated structure. The distal end of the clamp rod 21 can be transmission-connected to at least one of the two clamp heads. When the clamp rod 21 drives the clamp head transmission-connected thereto to rotate, the two clamp heads can move relatively away from or closer to each other, thereby enabling the two clamp heads to clamp tissue. The proximal end of the clamp rod 21 can be provided with a mounting portion 213, which can have a mounting hole.

[0075] The cutting mechanism 22 may include a knife bar 222 and a cutting blade 221. The cutting blade 221 may be disposed at the distal end of the knife bar 222, i.e., the end of the knife bar 222 away from the housing assembly 1. A mounting structure may be provided at the proximal end of the knife bar 222. The knife bar 222 may be capable of sliding relative to the mounting structure. The mounting structure is configured to cooperate with the mounting portion 213 at the proximal end of the clamp rod 21, and may be, for example, detachably mounted on the mounting portion 213.

[0076] Therefore, during the assembly process of the integrated rod clamp structure of this embodiment, the distal end of the cutting mechanism 22 can be inserted into the interior of the clamp rod 21 through the mounting hole, and then the cutting mechanism 22 can be connected to the clamp rod 21 through the cooperation of the mounting structure and the mounting portion 213. At this time, the proximal end of the knife rod 222 can be exposed and arranged with the proximal end of the clamp rod 21. By pushing the proximal end of the knife rod 222 relative to the clamp rod 21, it is moved relative to the mounting structure, that is, when it moves relative to the clamp rod 21, the cutting blade 221 set on the distal end of the knife rod 222 can also be pushed forward, and then enter the knife groove of the clamp head, and be pushed along the knife groove, thereby cutting the tissue clamped by the two clamp heads.

[0077] When the electrosurgical instrument needs to be cleaned after use, or the cutting blade 221 needs to be replaced, the mounting structure and the mounting portion 213 can be disassembled and matched first, and then the knife rod 222 can be pulled out of the clamp rod 21. After that, the entire cutting mechanism 22 can be directly replaced, or the cutting blade 221 can be removed and replaced with a new cutting blade 221, or the entire cutting mechanism 22 can be cleaned, sterilized, and disinfected.

[0078] Therefore, when the cutting mechanism 22 is installed, after its distal end is inserted into the interior of the clamp rod 21 through the mounting hole, the mounting structure cooperates with the mounting portion 213 to connect the cutting mechanism 22 to the clamp rod 21. The installation process is relatively convenient, and the proximal end of the knife rod 222 is exposed from the proximal end of the clamp rod 21. The proximal end of the knife rod 222 can be pushed relative to the clamp rod 21 to drive the cutting blade 221 to be pushed along the knife groove, so that the cutting blade 221 of the rod assembly 2 after assembly is completed can be pushed stably and accurately to ensure a stable and reliable cutting effect; when the cutting mechanism 22 is dismantled, the mounting structure is disengaged from the mounting portion 213, and the knife rod 222 can be pulled out from the distal end of the clamp rod 21, so that its cutting blade 221 can be quickly and rapidly removed, thereby cleaning, disinfecting, and sterilizing the rod assembly 2, or replacing the cutting blade 221, thereby improving the reliability and safety of the reuse of high-frequency surgical instruments.

[0079] The shell assembly 1 may include a bracket 41, and a knife rod driving mechanism 44 and a clamp rod driving mechanism 42 arranged on the bracket 41. The portion of the rod assembly 2 located in the shell assembly 1 may be at least partially inserted in the bracket 41. The knife rod driving mechanism 44 is connected to the proximal end of the knife rod 222 of the integrated rod clamp structure through transmission, and the clamp rod driving mechanism 42 is connected to the proximal end of the clamp rod 21 of the integrated rod clamp structure through transmission.

[0080] As a specific example, the clamp rod 21 may include a clamp rod guide shaft 211, which may be provided with a toggle slot 212 for engaging with the clamp rod drive mechanism 42. The outer rod 23 may include an outer rod base 231, which may be provided with a positioning slot 232 for engaging with the housing assembly 1 to connect the outer rod 23 to the housing assembly 1. In addition, to prevent short circuits between metal components within the integrated clamp structure, a first insulating layer 24 may be provided between the clamp rod 21 and the outer rod 23, and a second insulating layer 25 may be provided on the outer side of the outer rod 23.

[0081] As a specific example, the mounting structure at the proximal end of the knife rod 222 includes a knife rod knob 223, and the knife rod knob 223 includes a knife rod base 226. One end of the knife rod base 226 can be provided with a mounting protrusion, and the other end of the knife rod base 226 is provided with an operating part 4411. The mounting protrusion is used to cooperate with the mounting part 213, so as to install the knife rod knob 223 on the clamp rod 21. The operating part 4411 is a plurality of ridges 4413 arranged around the outer peripheral surface of the knife rod 222. The operating part 4411 is used to apply force during installation to improve the editability of the installation; the knife rod base 226 can be a hollow structure, and the knife rod 222 can be slidably inserted in the knife rod base 226, so that the knife rod can slide relative to the knife rod knob 223.

[0082] As a further optimization, the proximal end of the knife bar can be provided with a knife bar drive unit 225, which is used to cooperate with the knife bar drive mechanism 44 of the bipolar electrocoagulation forceps. The knife bar is provided with a knife bar reset member 224, one end of which cooperates with the knife bar knob 223, and the other end of which cooperates with the knife bar drive unit 225. The knife bar reset member 224 is used to reset the knife bar 222. When the cutting operation is not in progress, the proximal end of the knife bar 222 is supported by the knife bar reset member 224, thereby preventing the cutting blade 221 from being pushed along the knife groove at the wrong time. When cutting is in progress, the proximal end of the knife bar 222 moves and forces the knife bar reset member 224 to be compressed. After the cutting is completed, the knife bar reset member 224 recovers its deformation and drives the proximal end of the knife bar 222 to reset.

[0083] In addition, the knife rod driving part 225 is provided with a driving surface 227 on the side away from the knife rod knob 223, and a positioning groove or a positioning protrusion is provided on the driving surface 227. The positioning groove and the positioning protrusion are used to cooperate with the slider 443 of the control component 4. The slider 443 can slide relative to the bracket 41 of the control component 4, thereby driving the knife rod 222 to slide.

[0084] The outer diameter of the end of the knife rod driving part 225 close to the knife rod knob 223 is larger than the outer diameter of the knife rod 222, and the outer diameter of the end of the knife rod knob 223 close to the knife rod driving part 225 is larger than the outer diameter of the knife rod 222. The knife rod reset part 224 is a compression spring, one end of the compression spring cooperates with the end of the knife rod driving part 225 close to the knife rod knob 223, and the other end of the compression spring cooperates with the end of the knife rod knob 223 close to the knife rod driving part 225.

[0085] As a further optimization, refer to Figure 13 , and also includes a blade guide 35, which is connected to the distal end of the clamp rod 21, one end of the blade guide 35 is in transmission cooperation with at least one of the two clamp heads, and the other end of the blade guide 35 is provided with a blade guide groove 352 for guiding the blade into the knife groove. When the rod assembly 2 is installed, the front end of the cutting blade 221 can be guided by the blade guide groove 352 and slide into the knife groove, thereby preventing the front end of the cutting blade 221 from interfering with the blade guide 35 and damaging the cutting blade 221.

[0086] As a specific example of the blade guide 35, refer to Figure 14 The blade guide 35 can be provided with a blade slot 356 along its axial direction. The guide slot can be connected to the blade slot 356, and the size of the guide slot increases gradually from the connection point between the guide slot and the blade slot 356 to the outside, and forms at least one guide bevel, which is used to guide the front end of the cutting blade 221 into the blade slot.

[0087] As a more specific example, the blade guide 35 may include a mounting end 351 and a driving end 355 , wherein the mounting end 351 is used to connect with the pliers rod 21 , and the driving end 355 is used to be drivingly connected with at least one of the two pliers heads.

[0088] As an example, the two pliers include a first pliers 31 and a second pliers 32. The first pliers 31 is fixedly connected to the distal end of the outer rod 23, and the second pliers 32 is rotatably connected to the first pliers 31 through a connecting pin 33. A pliers drive slot 321 is provided on the second pliers 32; a drive pin 34 is provided on the blade guide 35, and the drive pin 34 is inserted into the pliers drive slot 321 and cooperates with the pliers drive slot 321 for transmission.

[0089] As a further optimization solution, the second pliers 32 includes at least one connecting ear, a driving groove is opened on the connecting ear, and a receiving groove for accommodating at least part of the connecting ear is opened on the blade guide 35, and the driving pin 34 is located in the receiving groove. When the knife rod 222 moves, the driving pin 34 on the blade guide 35 slides in the driving groove, thereby causing the second pliers 32 to rotate.

[0090] When the second pliers head 32 has two connecting ears, the blade guide 35 may have a first receiving groove 354 and a second receiving groove 357. The two connecting ears are respectively inserted into the first receiving groove 354 and the second receiving groove 357. The first receiving groove 354 is provided with a first mounting hole 353, and the second receiving groove 357 is provided with a second mounting hole 358. In order to avoid the cutting blade 221, two driving pins 34 may be provided. One driving pin 34 is connected to the first mounting hole 353 and cooperates with one of the two connecting ears. The other driving pin 34 is connected to the second mounting hole 358 and cooperates with the other of the two connecting ears.

[0091] As an embodiment of the knife bar drive mechanism 44, refer to Figure 15 and 16The knife bar driving mechanism 44 may include a blade trigger 441 , a connecting mechanism 442 and a slider 443 , and the blade trigger 441 , the connecting mechanism 442 and the slider 443 may be arranged on the bracket 41 of the control component 4 . Among them, the slider 443 is slidably connected to the bracket 41, and the blade trigger 441 is connected to the slider 443 through a connecting mechanism 442. The blade trigger 441 and the bracket 41 can be rotatably connected or slidably connected; the slider 443 abuts against the proximal end of the knife rod 222, that is, the end of the knife rod 222 closer to the shell assembly 1, so that when the blade trigger 441 moves relative to the bracket 41, the slider 443 is driven to slide relative to the bracket 41 through the connecting mechanism 442, and the slider 443 pushes the proximal end of the knife rod 222 by contact and abutment, thereby driving the cutting blade 221 on the distal end of the knife rod 222 to advance along the first direction to cut the tissue clamped by the clamp, and the first direction can be the axial direction of the rod assembly 2; the direction in which the knife groove on the pliers head extends is usually the first direction, or approximately the first direction.

[0092] Therefore, in this embodiment, the slider 443 is slidably connected to the bracket 41 and is used to abut against the end of one end of the knife rod 222 of the cutting mechanism 22, so that there is no connection relationship between the slider 443 and the knife rod 222. The rod assembly 2 with the knife rod 222 can be directly removed without removing the slider 443, which is more convenient. At the same time, when the blade trigger 441 moves relative to the bracket 41, the slider 443 is driven to slide relative to the bracket 41 through the connecting mechanism 442 to push the end of one end of the knife rod 222 of the cutting mechanism 22, thereby driving the cutting blade 221 at the other end of the knife rod 222 to advance along the first direction. Without connecting the slider 443 to the knife rod 222, the knife rod 222 can be stably pushed to achieve reliable cutting of the tissue.

[0093] As a specific example of the structure of the blade trigger 441 in this embodiment, the blade trigger 441 may include an operating portion 4411 and a limiting portion 4412. When a user holds the bipolar coagulation forceps, the operating portion 4411 can be used to drive the blade trigger 441. The limiting portion 4412 is used to limit the blade trigger 441 along a predetermined path. More specifically, the operating portion 4411 can be protruding from the exterior of the bracket 41, and the housing assembly 1 has an avoidance groove at a position corresponding to the operating portion 4411, so that the operating portion 4411 protrudes from the housing assembly 1. The limiting portion 4412 is at least partially disposed within the interior of the bracket 41, and the limiting portion 4412 can be provided with a ridge 4413. A limiting structure can be provided at a position on the bracket 41 corresponding to the ridge 4413. The limiting structure can be a sliding groove or a limiting protrusion. The ridge 4413 cooperates with the limiting structure to limit the movement path of the blade trigger 441.

[0094] For example, when the blade trigger 441 and the bracket 41 are rotatably connected, the ridge 4413 can be set as an arc structure with the hinge point of the blade trigger 441 and the bracket 41 as the center of the circle, and the limiting structure can be two limiting protrusions set in pairs, and the two limiting protrusions are respectively located on both sides of the ridge 4413 to limit the movement path of the blade trigger 441.

[0095] In addition, the limiting portion 4412 may be provided with a stop portion 4416 for defining the end point of the movement of the blade trigger 441, thereby preventing the blade trigger 441 from overtravel and damaging the knife bar 222 and the cutting blade 221. Specifically, the stop portion may be a generally diamond-shaped protrusion, with two opposing corners of the protrusion located on either side of the ridge 4413. When the protrusion abuts / interferes with the limiting protrusion on the bracket 41 during the movement of the blade trigger 441, the blade trigger 441 reaches the middle of its movement.

[0096] As an example of the connecting mechanism 442, the connecting mechanism 442 includes at least one connecting rod. A connecting block 4414 may be provided on the side of the operating portion 4411 of the blade trigger 441 facing the connecting structure. The side of the connecting block 4414 facing away from the operating portion 4411 may be hinged to the connecting rod, and the side of the connecting rod facing away from the operating portion 4411 may be hinged to the slider 443. Specifically, the end of the connecting rod hinged to the connecting block 4414 is a first end, and the end hinged to the slider 443 is a second end. The first end and the connecting block 4414 may be connected via a second shaft 4433, and the second end and the slider 443 may be connected via a third shaft. Alternatively, a structure similar to a shaft shoulder may be provided on the slider 443, and the second end may be sleeved onto the slider 443 to achieve the hinged connection between the two.

[0097] To improve the stability of the connection, at least two connecting rods may be provided. For example, the connecting rods may include a first connecting rod 4421 and a second connecting rod 4422. The first end of the first connecting rod 4421 and the first end of the second connecting rod 4422 may be simultaneously hinged to both sides of the connecting block 4414 via a second shaft 4433, and the second end of the first connecting rod 4421 and the second end of the second connecting rod 4422 may be simultaneously hinged to both sides of the slider 443. In the bipolar electrocoagulation forceps, the knife rod 222 of the rod assembly 2 may pass through the blade trigger 441, and its proximal end abuts against the slider 443, so that when the knife rod 222 is pushed, the first connecting rod and the second connecting rod are respectively located on both sides of the knife rod 222.

[0098] In addition, one side of the slider 443 may be provided with a first hinge portion 4431 and a first limit key 4432, and the other side of the slider 443 may be provided with a second hinge portion and a second limit key; the bracket 41 may include a first connecting plate 415 and a second connecting plate 416, the first connecting plate 415 is provided with a first guide groove 413 along the first direction, and the second connecting plate 416 is provided with a second guide groove 414 at a position corresponding to the first guide groove 413, the first connecting rod 4421 is connected to the first hinge portion 4431, the second connecting rod 4422 is connected to the second hinge portion, the first limit key 4432 cooperates with the first guide groove 413, and the second limit key cooperates with the second guide groove 414.

[0099] As a further optimization, the push-blade structure further includes a trigger reset member 445 for resetting the blade trigger 441. This member is used to keep the blade trigger 441 in its initial position when the user does not activate the blade trigger 441, thereby preventing the cutting blade 221 from being pushed into the pliers head at the wrong time. Specifically, the trigger reset member 445 can be a torsion spring. The connecting block 4414 and the bracket 41 can be connected via a first shaft 444. The torsion spring is sleeved on the first shaft 444. One leg of the torsion spring engages with the bracket 41 or the housing assembly 1, and the other leg of the torsion spring engages with the connecting block 4414.

[0100] In addition, a receiving groove 4415 can be provided on the connecting block 4414, and at least a portion of the torsion spring can be accommodated in the receiving groove 4415. For example, one leg of the torsion spring that cooperates with the bracket 41 or the shell assembly 1 can be exposed in the receiving groove 4415, while the remaining portion is accommodated in the receiving groove 4415.

[0101] As an embodiment of the clamp rod driving mechanism 42, the clamp rod driving mechanism 42 may include a trigger member, which includes a first operating portion 421, a second operating portion 422, and a connecting portion 429. The first operating portion 421 and the second operating portion 422 are disposed at the lower end of the connecting portion 429, and the first operating portion 421, the second operating portion 422, and the connecting portion 429 form a generally Y-shaped overall structure. The upper end of the connecting portion 429 is transmission-connected to the clamp rod 21, and the connecting portion 429 is rotatably connected to the bracket 41, so that the clamp rod driving mechanism 42 can be rotatably connected to the bracket 41 via the connecting portion 429. When using the bipolar electrocoagulation forceps of this embodiment, by toggling the first operating portion 421, the trigger member rotates relative to the bracket 41, and the connecting portion 429 drives the clamp rod 21 to slide along the axis of the rod assembly 2, thereby driving the clamp head to move.

[0102] Reference Figure 19A button receiving groove 228 may be provided on the second operating portion 422, and the button receiving groove 228 is used to install the activation button 43, and the activation button 43 can be sealed and connected to the button receiving groove 228. For example, a sealing structure is provided between the button receiving groove 228 and the activation button 43, or the button receiving groove 228 and the activation button 43 are glued together with sealant to prevent liquids such as cleaning fluid from entering the activation button 43.

[0103] Therefore, the upper end of the connecting portion 429 is transmission-connected to the clamp rod 21 of the bipolar coagulation forceps, and the clamp rod 21 is used to drive the clamp head to open and close, so that the clamp head control structure of the utility model can control the clamp head more conveniently and reliably; the activation button 43 is sealed and connected to the accommodating groove 4415, so the clamp head control structure of the utility model can operate the activation button 43 more conveniently, thereby improving the convenience and reliability of the operation of the bipolar coagulation forceps, and because the activation button 43 is sealed and connected, when the bipolar coagulation forceps are cleaned, disinfected, and sterilized, cleaning fluid and other liquids are not easy to enter the activation button 43, thereby preventing damage to the electronic components in the activation button 43.

[0104] As a specific example, the activation button 43 may include a pressing member and an electronic switch. The pressing member can be pressed by the user and deformed when subjected to force / compression to trigger the electronic switch, thereby electrically connecting the conductive sheet on the forceps head to the high-frequency electrosurgical energy platform. The electronic switch is disposed in the receiving groove 4415. The pressing member is sealedly connected to the second operating portion 422. After the pressing member is sealedly connected to the second operating portion 422, the pressing member can completely cover the receiving groove 4415, thereby sealing the electronic switch in the receiving groove 4415 and preventing liquids such as cleaning fluid from entering the activation button 43 and damaging the electronic switch.

[0105] More specifically, the pressing member includes a pressing portion and a connecting portion 429. The connecting portion 429 is adhesively connected to the receiving groove 4415. The pressing portion can be protruded from the surface of the second operating portion 422 to facilitate the user's pressing. The pressing portion is preferably made of a flexible material such as rubber, plastic, silicone, or any other deformable and waterproof material.

[0106] The trigger member may be hollow, and the upper end of the connecting portion 429 may be provided with a connection hole 427, which communicates with the receiving slot 4415 and is used for wiring. Specifically, the wires used to electrically connect the electronic switch and the high-frequency electrosurgical energy platform can enter the trigger member through the connection hole 427, pass through the receiving slot 4415, and then be electrically connected to the electronic switch.

[0107] As an embodiment of the trigger member, a hinge shaft 423 may be provided on each side of the connecting portion 429, and the bracket 41 includes a first side plate 411 and a second side plate 412. The two hinge shafts 423 are respectively connected to the first side plate 411 and the second side plate 412. Specifically, the bracket 41 may include a first side plate 411, a second side plate 412, a first connecting plate 415 and a connecting seat 417. The first connecting plate 415 and the connecting seat 417 are arranged in front and back. The first side plate 411 and the second side plate 412 are located on both sides of the first connecting plate 415 and the connecting seat 417. The distal end of the first side plate 411 and the distal end of the second side plate 412 are respectively connected to both sides of the connecting seat 417, and the proximal end of the first side plate 411 and the proximal end of the second side plate 412 are respectively connected to both ends of the first connecting plate 415. In addition, in order to ensure the stability of the bracket 41, a second connecting plate 416 can also be provided. The second connecting plate 416 is located at the proximal end of the bracket 41, that is, the second connecting plate 416 is respectively connected to the proximal end of the first side plate 411 and the proximal end of the second side plate 412, and the second connecting plate 416 is located below the first connecting plate 415.

[0108] As a further optimization, the trigger member may be provided with a clamp rod reset member 424. The trigger member generally has at least two states: in the initial state, the trigger member does not drive the clamp rod 21, and the clamp heads are in the open state; in the clamping state, the trigger member drives the clamp rod 21 to slide, thereby driving the two clamp heads to rotate relative to each other, so that the clamp heads are in the closed state. Therefore, the clamp rod reset member 424 is used to maintain the trigger member in the initial state to prevent the clamp heads from being accidentally operated.

[0109] Specifically, at least one of the two hinge shafts 423 of the connecting portion 429 is provided with a reset member. One end of the reset member engages with the trigger member, and the other end engages with the bracket 41. When a user applies force to the first operating portion 421 of the trigger member, the trigger member rotates relative to the bracket 41, forcing the reset member to deform. When the user stops applying force to the first operating portion 421, the reset member recovers its deformation, driving the trigger member to rotate, thereby driving the pliers rod 21 to open the pliers. The reset member can be a spring, such as a torsion spring, a tension spring, or a compression spring.

[0110] As another embodiment of the clamp rod driving mechanism 42, refer to Figure 17 and 18 The upper end of the connecting portion 429 of the trigger member may be provided with a driving portion 425. The driving portion 425 and the connecting portion 429 may be detachably connected, such as by a snap connection, a threaded connection, a form fit, etc. The driving portion 425 is in transmission engagement with the pliers rod 21, so that the trigger member can be transmission-connected to the pliers rod 21 via the driving portion 425.

[0111] Specifically, the driving part 425 may have a mating groove generally in the shape of a reversed U. A clamp rod driving groove 426 may be formed in the groove wall of the mating groove. At least a part of the clamp rod 21 is accommodated in the mating groove, and a driven part cooperating with the clamp rod driving groove 426 is provided on the clamp rod 21. When the trigger part rotates relative to the bracket 41, the driving part 425 drives the driven part to move through the clamp rod driving groove 426, and further drives the clamp rod 21 to move.

[0112] More specifically, the opening direction of the clamp rod driving groove 426 intersects with the axial direction of the clamp rod 21, and at least a part of the driven part is located in the driving groove. At this time, since the clamp rod 21 is slidably connected to the bracket 41, when the trigger part rotates relative to the bracket 41, the freedom degree of the clamp rod 21 is limited and it can only slide relative to the bracket 41 along its own axial direction. The part of the driven part located in the driving groove slides in the clamp rod driving groove 426, but always cooperates with the clamp rod driving groove 426, so as to convert the rotation of the trigger part into the sliding of the clamp rod 21.

[0113] The above has schematically described the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
