Description

Technical Field

[0001] This invention relates to the field of surgical instrument technology, and more specifically to a scissor-type integrated electric surgical instrument. Background Technology

[0002] An electrosurgical instrument is a multifunctional surgical instrument that combines ultrasonic energy and high-frequency energy. Its operating end features openable jaws and a retractable blade, enabling it to perform multiple functions, including tissue clamping, high-frequency electrocoagulation of tissue, and tissue cutting with the blade.

[0003] Electrically-integrated surgical instruments require internal jaw control mechanisms to control the opening and closing of the jaws for tissue clamping, and blade control mechanisms to control the extension and retraction of the blade to cut tissue. Currently, these jaw and blade control mechanisms are independent and uncoordinated during operation. This results in poor actuation between the jaws and blade, with both jaw opening and blade extension controlled entirely by the operator. This is prone to errors, such as the blade extending while the jaws are open, leading to accidental injury or tissue cutting. This poses risks and causes significant inconvenience to the use of surgical instruments. Therefore, ensuring the safe use of the jaws and blades of electrically-integrated surgical instruments is an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a scissor-type integrated electric surgical instrument.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A scissor-type electrosurgical instrument includes a first shaft member and a second shaft member pivotally connected to form a scissor-like structure. The first and second shaft members extend forward from their pivot connection point to form an openable jaw, and extend backward to form a hollow first housing and a hollow second housing. A blade and a control mechanism for controlling the extension and retraction of the blade within the jaw are disposed within the first housing. The control mechanism includes a drive mechanism for moving the blade and a trigger mechanism for opening the drive mechanism. The drive mechanism includes a rocker arm, a rotating arm, and a blade infeed handle connected in sequence. The rocker arm is connected to the blade. The blade infeed handle is located outside the first housing and drives the rotating arm to rotate synchronously around the connection point. The rotation of the rotating arm drives the rocker arm to move the blade synchronously. The trigger mechanism includes a spring support and a limiting fork. The limiting fork is pivotally connected to a round pin within the first housing, and its outer end protrudes from the inner wall of the first housing. Its inner end engages with the spring support. The limiting fork drives the spring support to move linearly by rotation, thereby engaging or disengaging the spring support from the rotating arm.

[0007] Preferably, a metal bracket is provided inside the first housing, a rotating shaft is inserted into the axis of the first end of the rotating arm, a slot is symmetrically provided on the surface of the rotating shaft, the rotating shaft passes through the metal bracket, and one or both ends of the rotating shaft are connected to the feed handle.

[0008] Preferably, the outer surface of the first end is an arc surface, and a limiting slot is formed at the connection between the arc surface and the rod body of the rotating arm. The end of the spring bracket is provided with a protrusion that matches the limiting slot. The movement of the spring bracket drives the protrusion to engage or disengage from the limiting slot.

[0009] Preferably, a protruding rod is provided at the second end of the rotating arm. The protruding rod passes through the end connection hole of the rocker arm and moves in an arc around the rotation axis. A limiting groove is provided on the metal bracket that matches the movement trajectory of the protruding rod, and the protruding rod is slidably locked in the limiting groove.

[0010] Preferably, the drive mechanism further includes a reset spring, one end of which is sleeved on a groove at the end of the rocker arm, and the other end is disposed on the inner wall of the first housing. The elastic force of the reset spring drives the rocker arm and the rotary arm to return to their initial state.

[0011] Preferably, the spring bracket includes a support rod and a return spring that are sleeved together. The protrusion is disposed at the front end of the support rod. The support rod is provided with a round protrusion that engages with the inner end of the limiting fork. The limiting fork drives the support rod away from the first end, and the return spring drives the support rod to return to its original position.

[0012] Preferably, the metal bracket is provided with a straight support rod groove, and the back of the support rod has a slider, which is slidably embedded in the support rod groove.

[0013] Preferably, the triggering mechanism further includes a spring plate disposed within the first housing. The side of the limiting fork has a protrusion that can actuate the spring plate. When the spring bracket separates from the rotating arm, the protrusion moves from the inside to the outside of the spring plate to actuate the spring plate and emit a prompt sound.

[0014] Preferably, the first shaft component further includes a first connecting portion and a first clamping arm connected to the first housing, and the second shaft component further includes a second connecting portion and a second clamping arm connected to the second housing. The first connecting portion is provided with two connecting cylinders, and the second connecting portion is rotatably provided with a welding disc. The welding disc is welded to the connecting cylinders, so that the first connecting portion and the second connecting portion are pivotally connected, and the first clamping arm and the second clamping arm constitute the jaws.

[0015] Preferably, both the first clamp arm and the second clamp arm have an insulating shell, and the front ends of the first connecting part and the second connecting part are respectively inserted into the insulating shell. The inner surfaces of the first clamp arm and the second clamp arm are provided with electrode plates connected to the switch wires by wires. Each electrode plate is provided with at least one insulating sheet, and each electrode plate has a blade groove at its axis that allows the blade to pass through.

[0016] Preferably, the outer sidewalls of the tail ends of the first housing and the second housing are respectively provided with finger rings for holding, and a circuit board is provided inside the second housing between the two finger rings. The circuit board is provided with the switch, and the switch is provided with a spring button. The spring button protrudes outward from the inner sidewall of the second housing and is opposite to the inner sidewall of the first housing.

[0017] The beneficial effects of this invention are mainly reflected in:

[0018] 1. The trigger mechanism is set to lock the blade drive mechanism in the initial state, which effectively prevents the blade from extending or retracting when the jaws are open, thus avoiding the danger of accidental contact and injury, and ensuring safety in use.

[0019] 2. The limit fork and the elastic button of the switch in the triggering mechanism are located between the inner walls of the first housing and the second housing, so that clamping the first housing and the second housing can simultaneously close the jaws and unlock the blade drive mechanism, which greatly simplifies the operation steps and improves the efficiency and convenience of use.

[0020] 3. The limit fork rotates to actuate the spring and emits a prompt sound, which promptly informs the user that the trigger mechanism and drive mechanism have disengaged, prompting the user to rotate the feed handle, further improving ease of use. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0034] like Figures 1 to 10As shown, this invention discloses a scissor-type electrosurgical instrument, comprising a first shaft member and a second shaft member pivotally connected to form a scissor-like structure. The first and second shaft members extend forward from their pivot connection point to form an openable jaw, and extend rearward to form a hollow first housing 1 and a hollow second housing 2. A blade 3 is disposed within the first housing 1, and a control mechanism for controlling the extension and retraction of the blade 3 within the jaw is provided. The control mechanism includes a drive mechanism for driving the blade 3 to move and a trigger mechanism for controlling the opening of the drive mechanism. The drive mechanism includes a rocker arm 6, a rotating arm 4, and a cutting handle 5 connected in sequence. The rocker arm 6... Connected to the blade 3, the feed handle 5 is located outside the first housing 1 and drives the rotating arm 4 to rotate synchronously around the connection point of the two. The rotation of the rotating arm 4 drives the rocker arm 6 to drive the blade 3 to move synchronously. The triggering mechanism includes a spring bracket 7 and a limiting fork 8. The limiting fork 8 is pivotally connected to the round shaft pin 101 inside the first housing 1, and its outer end protrudes outward from the inner side wall of the first housing 1. Its inner end is engaged with the spring bracket 7. The limiting fork 8 drives the spring bracket 7 to make linear motion by rotation, thereby causing the spring bracket 7 to engage or disengage from the rotating arm 4. In the initial state, the jaws are open, the first housing 1 and the second housing 2 are separated, the end of the spring bracket 7 engages with the rotating arm 4 and restricts the rotation of the rotating arm 4, and the blade 5 is retracted into the first housing 1; in the second state, the jaws are closed, the inner walls of the first housing 1 and the second housing 2 are close but not in contact; in the third state, the jaws are closed, the inner walls of the first housing 1 and the second housing 2 are in contact under the pressure of a hand, at this time, the outer end of the limiting fork 8 abuts against the inner wall of the second housing 2 and rotates to drive the spring bracket 7 to separate from the rotating arm 4, the feed handle 5 can drive the rotating arm 4 to rotate, so that the blade 5 can extend and retract within the jaws.

[0035] Specific examples Figure 2-5As shown in Figure 7, a bracket 102 is provided inside the first housing 1. The bracket 102 is preferably made of metal. A rotating shaft 11 is inserted into the axis of the first end 401 of the rotating arm 4. A slot 1101 is symmetrically provided on the surface of the rotating shaft 11. The rotating shaft 11 passes through the metal bracket 102, and one or both ends of the rotating shaft 11 are connected to the feed handle 5. The slot 1101 makes the surface of the rotating shaft 11 non-circular, thereby ensuring that there is no relative rotation at the connection between the rotating shaft 11 and the first end 401 and the feed handle 5, and ensuring that the rotation of the feed handle 5 can drive the rotating arm 4 to rotate synchronously. In a preferred embodiment, the feed handle 5 is provided at both ends of the rotating shaft 11, so that the user can operate the feed handle 5 from both sides of the first housing 1 to simultaneously meet the left-hand and right-hand usage habits.

[0036] To further facilitate operation, the end of the feed handle 5 has a contact protrusion 501 with a larger diameter to increase the contact area of ​​the feed handle 5, improve the stability of the user's operation of the feed handle 5, and reduce slippage. The second housing 2 is provided with a recess 201 that matches the movement trajectory of the feed handle 5, further improving the smoothness and stability of the feed handle 5's movement. The portion of the second housing 2 that abuts against the limiting fork 8 also has an opening, allowing the top of the limiting fork 8 to be partially inserted into the second housing 2 and abut against the second metal bracket 202 inside the second housing 2, thereby improving the stability of the contact between the limiting fork 8 and the second housing 2. The top of the limiting fork 8 has an arc-shaped surface to minimize wear caused by hard contact with the second housing 2 and to facilitate the rotation of the limiting fork 8.

[0037] like Figure 5 , 7As shown, the outer surface of the first end 401 in this solution is an arc surface 4011, and a limiting slot 403 is formed at the connection between the arc surface 4011 and the rod body of the rotating arm 4. The end of the spring bracket 7 is provided with a protrusion 701 that matches the limiting slot 403. The movement of the spring bracket 7 drives the protrusion 701 to engage or disengage from the limiting slot 403. The protrusion 701 is preferably a cylindrical structure. The arc surface 4011 is provided so that when the spring bracket 7 is reset and retracted, even if the rotating arm 4 is not reset, the protrusion 701 will abut against the arc surface 4011 and will not hinder the rotation of the first end 401. When the first end 401 is rotated and reset, the protrusion 701 will slide along the arc surface 4011 until it engages with the limiting slot 403. In other feasible embodiments, other feasible snap-fit ​​structures may also be used between the first end 401 and the end of the spring bracket 7, such as forming a bayonet at the end of the spring bracket 7 and forming a protrusion at the outer edge of the first end 401.

[0038] Furthermore, a protruding rod 4021 is provided at the second end 402 of the rotating arm 4. The protruding rod 4021 passes through the end connection hole 601 of the rocker arm 6 and moves in an arc around the rotation axis 11. A limiting groove 10 matching the movement trajectory of the protruding rod 4021 is provided on the metal bracket 102, and the protruding rod 4021 is slidably engaged in the limiting groove 10. The limiting groove 10 can limit the movement range of the second end 402 of the rotating arm 4, thereby limiting the movement range and length of the blade 3. The limiting groove 10 can effectively ensure the movement stability and smoothness of the protruding rod 4021, minimize shaking, and avoid jamming of the blade 3.

[0039] The drive mechanism also includes a return spring 12. One end of the return spring 12 is fitted onto the slot 602 at the end of the rocker arm 6, and the other end is disposed on the inner wall of the first housing 1. The elastic force of the return spring 12 drives the rocker arm 6 and the rotating arm 4 to return to their initial state. The arrangement of the return spring 12 allows the rotating arm 4 to automatically return to its initial state when the feed handle 5 is not driven to rotate by external force. Compared with the manual mode controlled only by the feed handle 5, the arrangement of the return spring 12 can further simplify the operation and prevent the jaws from opening before the blade 3 is retracted, thus improving safety. On the other hand, the elastic force of the return spring 12 can offset part of the driving force generated by the rotation of the rotating arm 4, thus slowing down the movement, improving the control of the feed handle 5, and preventing unnecessary damage between the feed handle 5 and the first housing 1 due to excessive force.

[0040] like Figure 4-6 As shown, the spring bracket 7 includes a support rod 702 and a return spring 703 that are sleeved together. A protrusion 701 is disposed at the front end of the support rod 702. A circular protrusion 704 is provided on the support rod 702 that engages with the inner end of the limiting fork 8. The limiting fork 8 drives the support rod 702 away from the first end 401, and the return spring 703 drives the support rod 702 to return to its original position. In a preferred embodiment, the inner wall of the first housing 1 is a flat surface. The support rod 702 is arranged parallel to the inner wall of the first housing 1, and the moving direction of the support rod 702 is consistent with its extending direction, in order to minimize the radial width of the first housing 1, optimize the arrangement of components, and save internal space of the first housing 1. Of course, in other feasible embodiments, the support rod 702 may not be parallel to the inner wall of the first housing 1.

[0041] The metal bracket 102 is provided with a straight support rod groove 1021. The back of the support rod 702 has a slider 7021, which is slidably embedded in the support rod groove 1021. The extension direction of the support rod groove 1021 is consistent with the movement direction of the spring bracket 7, so that the support rod groove 1021 limits the movement of the spring bracket 7 and increases the lateral support force of the spring bracket 7, ensuring the linear movement of the spring bracket 7 and preventing lateral movement, thereby improving the stability and smoothness of the linear movement of the spring bracket 7.

[0042] Furthermore, the triggering mechanism also includes a spring plate 9, which is disposed within the first housing 1. The side of the limiting fork 8 has a protrusion 801 that can actuate the spring plate 9. When the spring bracket 7 separates from the rotating arm 4, the protrusion 801 moves from the inside to the outside of the spring plate 9 to actuate the spring plate 9 and produce a prompting sound. The spring plate 9 is preferably a metal sheet to prevent breakage and to produce a relatively crisp prompting sound with the protrusion 801. The prompting sound generated between the spring plate 9 and the protrusion 801 can promptly inform the user that the jaws have clamped the tissue between the electrode plates 18 and that the button 24 can be pressed to start electrocautery. At the same time, the spring bracket 7 has separated from the rotating arm 4, that is, the drive mechanism has been unlocked. The feed handle 5 can control the rotating arm 4 to rotate to drive the blade 3 to move and cut, which is convenient for actual operation and avoids damage caused by the user rotating the feed handle 5 when the triggering mechanism locks the drive mechanism.

[0043] like Figure 8-9As shown, the first shaft component in this solution further includes a first connecting portion 13 and a first clamping arm 14 connected to the first housing 1. The second shaft component further includes a second connecting portion 15 and a second clamping arm 16 connected to the second housing 2. The first connecting portion 13 is provided with two connecting cylinders 1301, and the second connecting portion 15 is rotatably provided with a welding disc 1501. The welding disc 1501 is welded to the connecting cylinders 1301, thereby pivotally connecting the first connecting portion 13 and the second connecting portion 15. The first clamping arm 14 and the second clamping arm 16 constitute the jaws. The first connecting portion 13 and the second connecting portion 15 are preferably made of metal.

[0044] In a preferred embodiment, the first clamp arm 14 and the second clamp arm 16 are symmetrically arranged and extend to one side. In other feasible embodiments, the first clamp arm 14 and the second clamp arm 16 may also have other shapes.

[0045] Specifically, both the first clamp arm 14 and the second clamp arm 16 have an insulating shell 17, which is preferably made of plastic coating. The front ends of the first connecting part 13 and the second connecting part 15 are respectively inserted into the insulating shell 17. The inner surfaces of the first clamp arm 14 and the second clamp arm 16 are provided with electrode plates 18 connected to the switch 21 wires via wires 20. The electrode plates 18 are the contact surfaces between the clamp jaws and the tissue after it is clamped and coagulated. Each electrode plate 18 is provided with at least one insulating sheet. The insulating sheet can be any shape known to those skilled in the art, and the material of the insulating sheet is not limited and can be made of any insulating material. In a preferred embodiment, the insulating sheet is preferably an insulating bump 19, which is preferably made of ceramic. The insulating protrusions 19 ensure that the two electrode pads 18 do not come into close contact when no tissue is being held in the jaws, thus guaranteeing insulation between the two electrode pads 18. In this design, the protrusions 19 are respectively provided at the front end or the middle of the electrode pads 18. In other feasible embodiments, multiple insulating protrusions 19 can also be provided on the electrode pads 18. An insulating spacer (not shown in the figure) is provided between each electrode pad 18 and the front end of the first connecting portion 13 and the second connecting portion 15 to separate the electrode pad 18 from the first connecting portion 13 and the second connecting portion 15.

[0046] To allow the blade 3 to extend and retract between the first clamping arm 14 and the second clamping arm 16, each electrode plate 18 is provided with a blade groove 1801 at its axis, through which the blade 3 can pass. The blade groove 1801 extends towards the inner wall of the metal bracket 102 near the first housing 1 to accommodate the blade 3 and provide sufficient sliding distance for the blade 3.

[0047] As shown in 1, 2, 3, and 10, finger rings 25 for hand grips are respectively provided on the outer side walls of the tail ends of the first housing 1 and the second housing 2. The outer wall of the finger ring 25 is covered with a protective soft rubber to improve the comfort of using the finger ring 25.

[0048] A circuit board 23 is disposed within the second housing 2 between the two finger rings 25. A switch 21 is disposed on the circuit board 23, and a resilient button 24 is disposed on the switch 21. The resilient button 24 protrudes from the inner wall of the second housing 2 and faces the inner wall of the first housing 1. The elasticity of the resilient button 24 comes from a spring 2401 disposed between it and the switch 21, which allows the resilient button 24 to reset after being pressed. The structure of the resilient button 24 protruding from the second housing 2 allows, in the second state, the inner wall of the first housing 1 to abut against the outer surface of the resilient button 24 to trigger the switch 21, enabling the electrode plate 18 to be energized.

[0049] In this design, the inner surfaces of the first housing 1 and the second housing 2 are preferably flat surfaces. During the opening and closing process of the jaws, the limiting fork 8 does not contact the flat surface of the second housing 2, the limiting fork 8 does not shift, and the protrusion 701 of the spring bracket 7 does not disengage from the limiting latch 403, meaning the rotating arm 4 does not unlock. When the jaws are fully closed, the second housing 2 and the second metal bracket 202 undergo elastic deformation and begin to contact the limiting fork 8. The limiting fork 8 then begins to shift, and the spring bracket unlocks from the limiting latch 403 of the rotating arm 4 under the action of the limiting fork 8. Simultaneously, this elastic deformation triggers the elastic button 24. This structural design further simplifies the operation steps and facilitates quick opening and use in a handheld state for clamping and cutting.

[0050] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0051] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
