Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a hand-controlled electrode device with rinsing and suction functions. Background Technology
[0002] During laparoscopic surgery, surgeons frequently use surgical electrodes to cut, electrocoagulate, or separate tissues. Simultaneously, they need to suction and irrigate the surgical site to ensure a clear, real-time surgical view. Currently, instruments with electrocoagulation and cutting functions, as well as irrigation and suction functions, are mostly two separate sets of medical devices. Surgeons switch between these devices as needed during the procedure, and this switching process can negatively impact the surgery, such as increasing the risk of bleeding, reducing surgical efficiency, and affecting surgical quality.
[0003] To address this issue, people have conducted exploration and research in long-term production and daily life practices. For example, a Chinese utility model patent discloses a bipolar electrocoagulation clamp device [application number: 201620641727.2]. This utility model patent includes a bipolar electrocoagulation clamp, a flow guiding component disposed on the bipolar electrocoagulation clamp, and a locking rod connecting the flow guiding component to the bipolar electrocoagulation clamp. The flow guiding component includes a drainage tube disposed on the bipolar electrocoagulation clamp, a shut-off valve disposed on the drainage tube, and a three-way valve connected to the drainage tube. One end of the drainage tube is provided with a sliding groove, a first locking hole, a second locking hole, and a flow guiding part. The first locking hole, the second locking hole, and the flow guiding part are disposed on the same side. The sliding groove is disposed on the side corresponding to the first locking hole, and the second locking hole is located between the first locking hole and the flow guiding part.
[0004] The above-mentioned solution improves some of the problems of the existing technology to a certain extent. However, the solution still has at least the following drawbacks: cumbersome operation, high risk of intraoperative bleeding, and low surgical efficiency. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a hand-controlled electrode device with rinsing and suction functions, which facilitates electrocoagulation and electrocautery, and allows for rapid switching to realize the functions of rinsing and suctioning the surgical site, avoiding the need to change instruments during operation, reducing the risk of bleeding, and effectively solving the problems in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a hand-controlled electrode device with rinsing and suction functions, comprising a handle and an adapter seat;
[0007] Handle: A hollow clamp bar is fixed at the top, and an electrode head is provided at the end of the clamp bar away from the handle;
[0008] Adapter tube holder: It has three ports. One port is connected to the clamp bar through an end sleeve. The other two ports are connected to the flushing tube and the suction tube respectively. The ends of the flushing tube and the suction tube extend outside the handle and are respectively provided with flushing tube connector and suction tube connector.
[0009] The handle is also equipped with a flushing button to turn the flushing tube on or off, and a suction button to turn the suction tube on or off.
[0010] Furthermore, the handle is provided with an insulating sleeve that fits onto the clamp bar, and the insulating sleeve slides in engagement with the clamp bar. The insulating sleeve is used to isolate the clamp bar and shield the electrode head.
[0011] Furthermore, the insulating kit includes an insulating tube two, which is sleeved on the outside of the clamp bar. One end of the insulating tube two is fixed with a rotating wheel, and the other end of the insulating tube two has a rounded corner and at least one drainage hole on the side of that end. The insulating kit also includes an insulating tube one that is fixedly sleeved on the electrode head.
[0012] Furthermore, the handle is equipped with an anti-disengagement locking device to restrict the axial sliding of the clamp bar. The anti-disengagement locking device limits the action of the clamp bar, and when opened, it can detach the clamp bar from the handle.
[0013] Furthermore, the end sleeve includes a sliding sleeve, a retaining sleeve, and a sealing ring. The rotating wheel is sleeved on the outside of the sliding sleeve. One end of the retaining sleeve is fixedly connected to the clamp rod, and the other end of the retaining sleeve is threadedly connected to the retaining sleeve. The retaining sleeve is inserted into the adapter pipe seat, and a sealing ring is provided on the outside of the retaining sleeve. The insertion and engagement of the end sleeve with the adapter pipe seat facilitates disassembly.
[0014] Furthermore, the anti-disengagement locking component includes a spring piece that snaps onto the end sleeve. The spring piece has a connecting hole in its middle that is larger than the outer diameter of the sleeve. The outer side of the sleeve has an annular groove that partially snaps onto the connecting hole. A locking button that is slidably provided on the handle to compress the spring piece and cause the connecting hole to move laterally is provided.
[0015] Furthermore, both the flushing and suction tubes are flexible tubes. A retaining spring is fixed inside the handle. The suction and flushing buttons have a shaft hole and a limiting hole in their middle. The limiting hole is an arc-shaped hole that coincides with the center of the shaft hole. The lower end of the suction and flushing buttons is a tube compression end that presses against the movable end of the retaining spring. A rotating shaft passing through the shaft hole of the suction and flushing buttons and a limiting post passing through the limiting hole of the suction and flushing buttons are fixed inside the handle. By compressing the deformable flushing and suction tubes through the tube compression end, the cross-section of the tubes is changed, thereby controlling the flow rate.
[0016] Furthermore, it also includes a latch that slides on the handle, and the suction and flushing buttons have a defining groove in the middle, into which the latch can be inserted. The groove is used to protect the suction and flushing tubes from being squeezed by the buttons when the instrument is not in use.
[0017] Furthermore, the top of the suction button has a protrusion, and an adjustment knob is rotatably connected to the handle. An adjustment block is fixed to the adjustment knob, and the adjustment block has a spiral surface that presses against the protrusion. By pressing the top of the suction button with the spiral surface, the tilt angle of the suction button is changed.
[0018] Furthermore, the handle is provided with a circuit board electrically connected to the electrode head, the circuit board is provided with electrode wires connected to an external circuit, and the circuit board is also provided with an electrocoagulation button and an electrocution button.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This hand-controlled electrode device with rinsing and suction functions has the following advantages:
[0020] 1. Facilitates electrocoagulation and electrocautery, and allows for rapid switching to achieve irrigation and aspiration of the surgical site, avoiding the need to change instruments during the operation and reducing the risk of bleeding;
[0021] 2. The clamp bar assembly, consisting of clamp bars, insulating tubes, and rotating wheels, can be detached from the handle for easy replacement and cleaning;
[0022] 3. Because an insulating tube is installed on the outside of the clamp bar, the electrode head of the clamp bar can be extended and retracted. During suction and rinsing, the electrode head is retracted into the insulating tube to avoid interference with the electrode head and damage to the tissue.
[0023] 4. The suction level is adjustable. By adjusting the tilt angle of the suction button with the adjustment knob, the squeezing stroke of the suction tube can be controlled, thereby achieving stepless adjustment of the flow rate in the suction tube. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figure 1-7 This embodiment provides a technical solution: a hand-controlled electrode device with rinsing and suction functions, including a handle 1 and an adapter 2;
[0034] Handle 1: A hollow clamp bar 19 is fixed at the top, and an electrode head 16 is provided at the end of the clamp bar 19 away from the handle 1. When using the electrode function, the electrode connection line is connected to the high-frequency host, the exposed electrode head 16 is moved, the electrocoagulation button 7 is pressed to activate the electrocoagulation function, and the electrocution button 8 is pressed to activate the electrocution function.
[0035] The handle 1 is provided with an insulating kit that is fitted onto the clamp bar 19, and the insulating kit slides into the clamp bar 19; the clamp bar 19 is rotatably connected to the handle 1, and is engaged with the spring piece 25 through the slot on the sleeve 22, which restricts the axial movement of the clamp bar 19; when the rotating wheel 20 is turned, the clamp bar 19 can rotate freely with the rotating wheel 20.
[0036] The insulating kit includes an insulating tube 18, which is sleeved on the outside of the clamp bar 19. One end of the insulating tube 18 is fixed with a rotating wheel 20, and the other end of the insulating tube 18 has a rounded corner 31 and at least one drainage hole 32 on its side. The insulating kit also includes an insulating tube 17 fixedly sleeved on the electrode head 16. The rounded corner makes the end of the insulating tube 18 that extends into the electrode head rounded, thereby reducing the risk of the insulating tube 17 scratching capillaries and causing tissue bleeding during operation. In addition, the drainage hole 32 can play an auxiliary drainage role during suction, preventing tissue or tissue fluid from blocking the electrode head 16 end of the insulating tube 18 and causing the suction to be interrupted, thus ensuring the smooth progress of the operation.
[0037] The end sleeve includes a sliding sleeve 21, a retaining sleeve 22 and a sealing ring 26. The rotating wheel 20 is sleeved on the outside of the sliding sleeve 21. One end of the retaining sleeve 22 is fixedly connected to the clamp rod 19, and the other end of the retaining sleeve 22 is threadedly connected to the retaining sleeve 22. The retaining sleeve 22 is inserted into the adapter seat 2, and a sealing ring 26 is provided on the outside of the retaining sleeve 22.
[0038] The handle 1 is provided with an anti-disengagement locking device that limits the axial sliding of the clamp rod 19; the anti-disengagement locking device includes a spring piece 25 that is snapped onto the end sleeve, the middle of the spring piece 25 has a connecting hole 29 that is larger than the outer diameter of the sleeve 22, the outer side of the sleeve 22 has an annular groove 30, the annular groove 30 is partially snapped onto the connecting hole 29, and a locking button 24 that is slidably provided on the handle 1 to squeeze the spring piece 25 to make the connecting hole 29 move laterally;
[0039] Since the connecting hole 29 of the spring piece 25 only partially locks the annular groove 30 of the sleeve 22, it ensures the connection between the sleeve 22 and the rotating wheel 20. At the same time, rotating the rotating wheel 20 can make its internal clamp 19 rotate synchronously without separation, thus adjusting the angle of the electrode head 16.
[0040] When it is necessary to disassemble the clamp bar 19, the rotating wheel 20, and the insulating tube, press the locking button 24 to deform the spring piece 25. The connecting hole 29 of the spring piece 25 moves laterally in a direction perpendicular to the clamp bar 19. Since the diameter of the connecting hole 29 is larger than the outer diameter of the ferrule 22, after the lateral movement, the annular groove 30 completely disengages from the connecting hole 29, and the ferrule 22 can then move inside the spring piece 25, directly pulling off the clamp bar 19, the rotating wheel 20, and the insulating tube.
[0041] When the locking button 24 is pressed, the button 24 squeezes the spring piece, causing the spring piece 25 to disengage from the slot of the sleeve 22, thereby allowing the clamp bar 19 to axially separate from the handle 1.
[0042] The adapter 2 has three ports. One port is connected to the clamp 19 via an end sleeve. The other two ports are connected to the flushing tube 11 and the suction tube 12, respectively. The ends of the flushing tube 11 and the suction tube 12 extend outside the handle 1, and the ends are respectively provided with flushing tube connector 13 and suction tube connector 14.
[0043] The adapter 2 and the handle 1 are fixedly connected to the handle 1 through the slot. Push the rotating wheel 20 forward axially to the limit position. The clamp 19 slides in the insulating tube 18, which can make the electrode head 16 retract into the insulating tube 27. At this time, the sleeve 22 and the spring piece 25 are still in the snap-fit state. Press the flushing button 23 to use the flushing function.
[0044] The handle 1 is also equipped with a flushing button 23 to turn on or off the flushing tube 11, and a suction button 5 to turn on or off the suction tube 12;
[0045] Both the flushing tube 11 and the suction tube 12 are flexible tubes. A retaining spring 10 is fixed inside the handle 1. The middle of the suction button 5 and the flushing button 23 has a shaft hole and a limiting hole. The limiting hole is an arc-shaped hole that coincides with the center of the shaft hole. The lower end of the suction button 5 and the flushing button 23 is a tube extrusion end that is in contact with the movable end of the retaining spring 10. A rotating shaft 28 that passes through the shaft hole of the suction button 5 and the flushing button 23 and a limiting post 27 that passes through the limiting hole of the suction button 5 and the flushing button 23 are fixed inside the handle 1.
[0046] Both the suction button 5 and the flushing button 23 rotate around the pivot 28. The limiting post 27 restricts the rotation angle of the suction button 5 and the flushing button 23. After the plug 6 is removed, the flushing pipe 11 and the suction pipe 12 are completely squeezed and closed. The flushing pipe 11 or the suction pipe 12 can only be opened when the suction button 5 or the flushing button 23 is pressed.
[0047] It also includes a pin 6, which is slidably mounted on the handle 1. The middle of the suction button 5 and the flushing button 23 has a limiting groove, and the pin 6 is inserted into the limiting groove of both at the same time. The top of the suction button 5 has a protrusion, and an adjustment knob 3 is rotatably connected to the handle 1. An adjustment block 4 is fixed on the adjustment knob 3, and the adjustment block 4 has a spiral surface that is in contact with the protrusion.
[0048] When in use, first pull out the pin 6. The pin 6 can be inserted into the limiting slot of the suction button 5 and the flushing button 23. The limiting post 27 on the handle prevents the suction button 5 and the flushing button 23 from rotating. At this time, the flushing tube 11 and the suction tube 12 are in the spring-loaded conduction state to prevent the suction tube and the flushing tube from failing to spring back after being compressed for a long time. When using the instrument, first pull out the pin 6.
[0049] The handle 1 is provided with a circuit board 9 electrically connected to the electrode head 16. The circuit board 9 is provided with an electrode wire 15 connected to an external circuit. The circuit board 9 is also provided with an electrocoagulation button 7 and an electrocution button 8. The electrocoagulation button 7 and the electrocution button 8 are slidably connected to the handle through the handle slot, and the other end of the button is in contact with the switch contact of the circuit board.
[0050] The working principle of the hand-controlled electrode device with rinsing and suction functions provided by this invention is as follows:
[0051] When using the electrode function, the electrode connection line is connected to the high-frequency host, the clamp rod assembly is moved to expose the electrode head 16, the electrocoagulation button 7 is pressed to activate the electrocoagulation function, and the electrocution button 8 is pressed to activate the electrocution function.
[0052] When using the suction function, the suction tube connector 14 is connected to the negative pressure device. Press the suction button 5 down, and the suction tube 12 is in the open state. The smoke generated during the surgery can be sucked out by the forceps. Release the suction button 5. Under the pressure of the retaining spring 10, the suction button 5 will press the suction tube tightly and close the suction tube. At this time, rotate the adjustment knob 3, which will drive the adjustment block 4 to rotate. The spiral inclined surface of the adjustment block presses down on the suction button 5, so that the suction tube slowly opens. The adjustment knob 3 can adjust the amount of smoke.
[0053] When using the flushing function, the flushing tube connector 13 is connected to the flushing device. Push the clamp bar forward to the limit position so that the electrode head 16 retracts into the insulating tube 18. Press the flushing button 23, and the flushing tube 11 is in the open state. The liquid can be flushed and aspirated through the clamp bar. Release the flushing button 23. Under the pressure of the retaining spring 10, the flushing button 5 will press the flushing tube, and the flushing tube will be closed.
[0054] When the flow rate of the suction tube 12 needs to be adjusted, the knob 3 is rotated to drive the adjustment block 4 to rotate. The spiral surface of the adjustment block 4 contacts the protrusion on the top of the suction button 5. Since the height of the spiral surface varies, the contact height between the spiral surface and the protrusion is different at different positions. Therefore, rotating the knob 3 can control the tilt angle of the suction button 5. The force and stroke of the lower tube squeezing end squeezing the suction tube 12 are different and can be infinitely adjusted as needed.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
