Description

Technical Field

[0001] This invention relates to the field of bipolar electrocoagulation devices, and more specifically to a bipolar electrocoagulation device with an attraction function. Background Technology

[0002] Bipolar electrocoagulation forceps, as surgical energy devices, are widely used for tissue cutting and hemostasis in minimally invasive surgery. They close tissues by generating a thermal effect through high-frequency current. However, this process leads to an increase in tissue temperature and causes thermal damage, while the tissue fluid vaporizes, producing a large amount of mist. This mist mixes with harmful fumes generated by the high temperature during surgery, severely interfering with the clarity of the surgical field and making it difficult for doctors to accurately identify anatomical structures, thus affecting the safety and efficiency of the operation.

[0003] To address smoke interference, existing technologies typically combine bipolar electrocoagulation forceps with a suction device. The suction device removes intraoperative fog and harmful fumes to keep the surgical field clean. However, this requires medical personnel to operate the bipolar electrocoagulation forceps with one hand for tissue manipulation and independently operate the suction device to absorb the fog with the other. In the stressful surgical environment, this demands highly coordinated hand movements, placing stringent requirements on the surgeon's ambidextrous abilities and increasing operational difficulty, fatigue, and the risk of error. Furthermore, the continuous generation of fog not only obscures critical surgical areas and prolongs surgical time but may also carry harmful particles that pollute the operating room air, potentially threatening the health of patients and medical staff. Therefore, although the suction device can partially alleviate the smoke problem, the reliance on separate tools and the two-handed operation mode is inefficient, limiting the application of bipolar electrocoagulation forceps in high-efficiency and precise surgeries. To address this, a bipolar electrocoagulation device with suction function is provided to solve the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a bipolar electrocoagulation device with suction function. This addresses the problem that in existing technologies, bipolar electrocoagulation forceps are typically used in conjunction with a suction device to deal with smoke interference. This requires medical personnel to operate the bipolar electrocoagulation forceps with one hand to perform tissue processing and independently operate the suction device to absorb the smoke with the other hand. In the stressful surgical environment, a high degree of coordination between the two hands is required, which places stringent demands on the medical personnel's bimanual coordination ability and increases the difficulty of operation, fatigue, and risk of error.

A suction mechanism is installed inside the handle. The suction mechanism includes a suction box and a first sealing plate. The suction box is fixedly installed on the handle and is in one-way communication with the guide tube. The first sealing plate is slidably installed inside the suction box and is connected to the traction column. The first sealing plate divides the suction box into front and rear chambers.

Both the first T-shaped rod and the second T-shaped rod are fastened to the fastening groove. An adjusting block is slidably disposed inside the handle, and a fastening block is slidably mounted on the adjusting block. A bidirectional screw is rotatably mounted inside the handle, and the adjusting block is threadedly connected to one side of the bidirectional screw.

[0009] In a preferred embodiment, the handle is rotatably mounted with a knob, the lower end of which is fixedly connected to a drive gear, and the bidirectional screw is fixedly connected to a transmission gear, wherein the drive gear meshes with the transmission gear.

[0010] In a preferred embodiment, the rear side of the suction box is connected to a one-way end, and smoke can be discharged from the rear side of the suction box along the one-way end. The front side of the suction box is in one-way communication with the guide pipe, and smoke can enter the front side of the suction box along the guide pipe. The first sealing plate is equipped with a one-way valve, allowing smoke to move from the front to the rear of the suction box. The first sealing plate is fixedly connected to a slide rod, which is slidably and sealed to the rear end of the handle. The slide rod is fixedly connected to the traction column.

[0011] In a preferred embodiment, the attraction mechanism further includes: An energy storage box is fixedly installed on the upper end of the suction box. The energy storage box is connected to the front side of the suction box, and the upper side of the energy storage box is connected to the outside.

In this device, the handle serves as the main operating component. Its internal traction mechanism drives the electrocoagulation forceps to perform clamping and electrocoagulation actions. Simultaneously, the suction mechanism on the handle is directly connected to the guide tube. The traction column drives the first sealing plate to slide, drawing in the generated smoke along the guide tube during electrocoagulation. This integrated design completely eliminates the reliance on two-handed coordination, significantly reducing the difficulty and fatigue for medical personnel, effectively minimizing the risk of errors caused by improper hand coordination, significantly improving the safety and efficiency of surgical procedures, and ensuring a clear surgical field throughout the electrocoagulation process.

Detailed Implementation

[0018] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0020] Example: like Figure 1 , 10 As shown, this embodiment provides a bipolar electrocoagulation device with suction function, including: The device includes a handle 1 and a guide tube 11. The guide tube 11 is detachably and fixedly mounted on the handle 1. An electrocoagulation forceps is hinged inside the guide tube 11. The electrocoagulation forceps include two symmetrically arranged forceps handles 12, both of which are hinged inside the guide tube 11. Forceps tips 121 are mounted at the ends of the forceps handles 12. A liquid supply port 123 is provided on the side of the forceps handle 12 near the forceps tip 121. A suction tube 124 is mounted on the side of the forceps handle 12 near the forceps tip 121. An integrated connector 13 is fixedly mounted on the guide tube 11. The integrated connector 13 is electrically connected to the two forceps tips 121. The integrated connector 13 has a liquid supply port connected to the forceps handle 12 and communicates with the liquid supply port 123. The integrated connector 13 also has a suction port connected to the forceps handle 12 and communicates with the suction tube 124.

[0021] The fluid supply port 123 can provide treatment fluid to the forceps tip 121, avoiding excessive damage to surrounding tissues due to high temperature after surgery; the suction tube 124 mounted on the side of the forceps handle 12 near the forceps tip 121 can absorb excess treatment fluid and tissue fluid, preventing residue in the body.

[0022] The handle 1 is equipped with a traction mechanism, which includes a traction column 15, which is slidably mounted inside the handle 1. The traction column 15 can slide to drive the electrocoagulation tweezers to open and close. The handle 1 is also equipped with a suction mechanism, which includes: a suction box 2, which is fixedly mounted on the handle 1 and is unidirectionally connected to the guide tube 11; and a first sealing plate 22, which is slidably mounted inside the suction box 2 and is connected to the traction column 15. The first sealing plate 22 can slide through the guide tube 11 to absorb smoke into the suction box 2.

[0023] During operation, the traction column 15 of the traction mechanism slides backward to drive the electrocoagulation tweezers to perform clamping and electrocoagulation actions. At the same time, since the suction mechanism on the handle 1 is directly connected to the guide tube in one direction, the traction column 15 drives the first sealing plate 22 to slide backward, which can absorb the smoke generated during the electrocoagulation process along the guide tube 11.

[0024] In one embodiment, such as Figure 5-6 As shown, the traction mechanism also includes: an adjusting handle 154, which is rotatably mounted on the handle 1, and a gear 155 is fixedly mounted on the end of the adjusting handle 154. An elastic cord 151 is fixedly connected to the middle of the electrocoagulation forceps. A traction assembly is installed between the traction post 15 and the elastic cord 151. The traction post 15 and the elastic cord 151 are detachably and fixedly connected through the traction assembly. A first spring 122 is installed between the electrocoagulation forceps. The first spring 122 can provide elasticity for the electrocoagulation forceps to return to its original position after clamping. A second spring 152 is fixedly installed between the traction post 15 and the handle 1. The second spring 152 can provide elasticity for the traction post 15 to return to its original position forward. A rack 153 that meshes with the gear 155 is fixedly installed on the lower side of the traction post 15.

[0025] Since the spacing between the electrocoagulation forceps is small, the elastic cord 151 provided here allows the traction column 15 to have a longer sliding traction distance. During the operation, medical staff can press the adjustment handle 154 with their fingers to drive the adjustment gear 155 to rotate. The adjustment gear 155 will then drive the rack 153 and the traction column 15 to slide backward. The sliding of the traction column 15 will pull the elastic cord 151, thereby causing the two forceps handles 12 to rotate towards each other, so that the two forceps tips 121 come together.

[0026] like Figure 9 As shown, the traction assembly includes: a first T-shaped rod 16, which is sealed and slidably mounted on the guide tube 11, and the first T-shaped rod 16 is fixedly connected to the elastic rope 151; a second T-shaped rod 161, which is fixedly mounted on the traction column 15, and a fastening assembly that allows the first T-shaped rod 16 and the second T-shaped rod 161 to be connected is assembled between them.

[0027] The first T-shaped rod 16 and the second T-shaped rod 161 can be connected by the fastening assembly, so that the traction column 15 can pull the elastic rope 151 to move during the sliding process.

[0028] like Figure 6 , 9 As shown, there are two fastening components, which are symmetrically arranged inside the handle 1. The fastening components include: a fastening block 162, which is assembled inside the handle 1, and a fastening groove 163 is opened on the inner side of the fastening block 162. Both the first T-shaped rod 16 and the second T-shaped rod 161 are fastened to the fastening groove 163; an adjusting block 164, which is slidably assembled inside the handle 1, and the fastening block 162 is slidably assembled to the adjusting block 164; and a bidirectional screw 165, which is rotatably assembled inside the handle 1, and the adjusting block 164 is threadedly rotatably connected to one side of the bidirectional screw 165.

[0029] like Figure 13 As shown, the handle 1 is equipped with a knob 166 for rotation. The lower end of the knob 166 is fixedly equipped with a drive gear 1661. The bidirectional screw 165 is fixedly equipped with a transmission gear 1662. The drive gear 1661 and the transmission gear 1662 mesh with each other.

[0030] Rotating the knob 166 drives the bidirectional screw 165 to rotate, thereby adjusting the sliding of the symmetrically arranged upper and lower adjustment blocks 164 towards or away from each other. This, in turn, adjusts the sliding of the symmetrically arranged upper and lower fastening blocks 162 towards or away from each other. In this way, the first T-shaped rod 16 and the second T-shaped rod 161 can be connected through the two fastening blocks 162. Since the fastening blocks 162 slide back and forth on the adjustment blocks 164, the movement of the traction column 15 can drive the elastic rope 151 to move synchronously. The detachable design allows the handle 1 and the guide tube 11 to be designed independently, enabling the replacement of electrocoagulation tweezers and guide tubes 11 with different tweezer tip 121 shapes.

[0031] Furthermore, after the elastic rope 151 is disconnected from the traction column 15 by turning the knob 166, the adjustment handle 154 can be pressed repeatedly to achieve the function of repeatedly absorbing mist and harmful smoke, which can further purify the air around the surgical site.

[0032] In one embodiment, such as Figure 7 , 10 As shown, the rear side of the suction box 2 is connected to a one-way end 211, and the smoke can be discharged from the rear side of the suction box 2 along the one-way end 211. The front side of the suction box 2 is unidirectionally connected to the guide pipe 11, and the smoke can enter the front side of the suction box 2 along the guide pipe 11. The first sealing plate 22 is equipped with a one-way valve 221, which allows smoke to move from the front to the rear of the suction box 2. The first sealing plate 22 is fixedly connected to a slide rod 23, which is slidably and sealed to the rear end of the handle 1. The slide rod 23 is fixedly connected to the traction column 15.

[0033] As the traction column 15 moves backward, the first sealing plate 22 slides backward, and the gas on the rear side of the first sealing plate 22 is discharged from the one-way end 211 by compressed air. At the same time, the front side of the first sealing plate 22 absorbs fog and harmful smoke through the guide tube 11, which can absorb the fog and harmful smoke generated when the electrocoagulation tweezers are working.

[0034] In a preferred embodiment, such as Figure 7 , 10 As shown, the attraction mechanism also includes: an energy storage box 21, which is fixedly installed on the upper end of the attraction box 2. The energy storage box 21 is connected to the front side of the attraction box 2, and the upper side of the energy storage box 21 is connected to the outside. A second sealing plate 24 is slidably fitted to the energy storage box 21, and a third spring 241 is fitted between its lower end and the energy storage box 21.

[0035] As the traction column 15 moves backward, the first sealing plate 22 slides backward, and compressed air discharges the gas behind the first sealing plate 22 from the one-way end 211. At the same time, the front of the first sealing plate 22 absorbs fog and harmful smoke through the guide tube 11. Simultaneously, the rapid suction pulls the second sealing plate 24 downward. The rebound speed of the second sealing plate 24 can be adjusted by setting a small hole for air intake. Subsequently, the second sealing plate 24 moves upward by relying on the third spring 241 and will continue to draw air from the guide tube 11 for a period of time. The energy storage box 21 can play the role of delaying the air intake function, so as to absorb the fog and harmful smoke generated when the electrocoagulation tweezers are working.

[0036] like Figure 9 As shown, the guide tube 11 is threadedly connected to the handle 1. The handle 1 is fixedly installed with a suction cover 25. The suction cover 25 is unidirectionally connected to the front side of the suction box 2. The end of the guide tube 11 is provided with several evenly distributed suction holes 141. Smoke can enter the front side of the suction box 2 along the suction holes 141 and the suction cover 25. The suction cover 25 and the end of the guide tube 11 can be sealed and abutted.

[0037] The suction hole 141 is designed to prevent the second sealing plate 24 from returning to its original position instantly, thus achieving a continuous suction effect.

[0038] like Figure 10 , 12 As shown, an annular gas hood 26 is fixedly installed inside the suction box 2. The annular gas hood 26 is in one-way communication with the suction hood 25. Smoke can enter the front side of the suction box 2 from the middle of the annular gas hood 26. The slide rod 23 is slidably connected to the middle of the annular gas hood 26. The slide rod 23 can block the air outlet in the middle of the annular gas hood 26. The middle of the slide rod 23 is provided with a suction ring groove 261, which can connect the annular gas hood 26 and the suction box 2.

[0039] As the traction column 15 begins to move backward, the annular air hood 26 is sealed by the slide rod 23. The first sealing plate 22 will draw air into the energy storage box 21. During this process, the second sealing plate 24 moves downward against the elasticity of the third spring 241. When the tip 121 of the electrocoagulation forceps is about to close, the space in front of the first sealing plate 22 is connected to the suction hood 25 through the suction ring groove 261 of the slide rod 23. At this time, the second sealing plate 24 returns to its original position upward by the elasticity of the third spring 241. At this time, the guide tube 11 will continuously generate suction to draw out the mist and harmful fumes generated during the medical process.

[0040] The working principle of the embodiments is explained in detail below: When using this device for treatment, first press the adjustment handle 154 with your thumb. The adjustment handle 154 drives the adjustment gear 155 to rotate. The adjustment gear 155 meshes with the rack 153, thereby driving the traction column 15 to slide backward against the elastic force of the second spring 152. The backward movement of the traction column 15 pulls the elastic rope 151 through the second T-shaped rod 161, the fastening assembly, and the first T-shaped rod 16. The elastic rope 151 then pulls the two handles 12 of the electrocoagulation forceps to rotate towards each other against the elastic force of the first spring 122 around their hinge point with the guide tube 11, causing the forceps tips 121 of the electrocoagulation forceps to close together, realizing the clamping or electrocoagulation operation of the tissue. During this process, since the forceps tips 121 are electrically connected to the external power device through the integrated connector 13, when the forceps tips 121 contact the tissue and meet the electrocoagulation conditions, a high-frequency current can be generated to electrocoagulate and stop the bleeding of the tissue. Meanwhile, if it is necessary to rinse and cool the surgical area, the external rinsing fluid can be delivered to the vicinity of the forceps tip 121 through the fluid supply port of the integrated connector 13 and the fluid supply port 123 of the forceps handle 12. Blood and tissue fluid near the forceps tip 121 are drawn into the suction device connected to the integrated connector 13 through the suction tube 124 and the suction port of the integrated connector 13.

[0041] As the traction column 15 moves backward, the slide rod 23, which is fixedly connected to it, drives the first sealing plate 22 to slide backward synchronously within the suction box 2. The gas behind the first sealing plate 22 is compressed, opening the one-way structure at the one-way end 211 and discharging from the one-way end 211. Since the one-way valve 221 on the first sealing plate 22 only allows gas to flow from front to back, a negative pressure is formed at the front of the first sealing plate 22. This negative pressure acts on the second sealing plate 24 inside the energy storage box 21 through the communication channel between the suction box 2 and the front of the energy storage box 21, overcoming the elastic force of the third spring 241 and pulling it downward. The upper side of the energy storage box 21 is connected to the outside, allowing the gas in the space above the second sealing plate 24 to be replenished. Until the suction ring groove 261 on the slide bar 23 moves to the annular air cover 26, the second sealing plate 24 slides upward by the elasticity of the third spring 241. The negative pressure is drawn from the side of the guide tube 11 near the forceps tip 121 through the suction hole 141 at the front of the suction box 2, the suction cover 25 and the end of the guide tube 11. The fog and harmful fumes generated by electrocoagulation near the forceps tip 121 are drawn into the front of the suction box 2 through the guide tube 11, so that the suction effect can be continuously generated when the forceps tip 121 is about to close and after it closes, ensuring a clear surgical field.

[0042] When medical staff release the adjusting handle 154, the restoring force of the second spring 152 pushes the traction column 15 forward to slide. The traction column 15 drives the adjusting handle 154 to reset via the rack 153 and adjusting gear 155. The tension of the elastic rope 151 disappears, and the handle 12 of the electrocoagulation forceps resets under the action of the first spring 122, and the tip 121 of the electrocoagulation forceps opens. The forward movement of the traction column 15 causes the sliding rod 23 and the first sealing plate 22 to slide forward. The air on the front side of the first sealing plate 22 moves to the rear side of the first sealing plate 22 through the one-way valve 221.

[0043] When it is necessary to change the tip 121 of the electrocoagulation forceps to a different shape or specification, medical staff can turn the knob 166. The knob 166 drives the drive gear 1661 to rotate. The drive gear 1661 meshes with the transmission gear 1662, which in turn drives the bidirectional screw 165 to rotate. The bidirectional screw 165 drives the two upper and lower adjusting blocks 164 connected to it to slide in opposite directions. The adjusting blocks 164 drive the locking block 162 to move synchronously in opposite directions, so that the locking groove 163 on the inner side of the locking block 162 disengages from the first T-shaped rod 16 and the second T-shaped rod 161. At this time, the guide tube 11 can be rotated and removed, and the guide tube 11, together with the forceps handle 12, the forceps tip 121 and the first T-shaped rod 16, can be removed from the handle 1. After replacing the new guide tube 11 assembly, tighten the guide tube 11 to complete the fixation, then turn the knob 166 in the opposite direction to make the bidirectional screw 165 drive the adjusting block 164 and the fastening block 162 to move towards each other, and the fastening groove 163 re-fastens the first T-shaped rod 16 and the second T-shaped rod 161, and it can be used for subsequent purposes.
