Bipolar electrocoagulation for nasal hemostasis and use method thereof

Abstract

This invention discloses a bipolar electrocoagulation device for nasal hemostasis, comprising a forceps barrel and a handle fixedly connected to the right side of the forceps barrel. A first slot is formed at the bottom right side of the forceps barrel, and a handle is slidably connected to the inner cavity of the first slot. In use, a button is pressed, and a locking block is pulled away from between two fixed blocks. Then, the handle is gripped with fingers and brought close to the handle. When the leftmost fixed block is in contact with the second stop plate, the button can be released, causing the locking block to fall between the two right-side fixed blocks and lock. Pushing the rack to the left moves the movable plate to the left, and the T-shaped rod pushes the suction tube horizontally to the left, causing the suction tube to protrude to the left side of the two forceps heads. This allows the surgeon to easily remove accumulated fluid around the surgical site, improving ease of use and ensuring thorough drainage of accumulated fluid, thus enhancing the surgical outcome.

Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a bipolar electrocoagulation device for nasal hemostasis and a use method thereof. Background Art

[0002] Currently, most minimally invasive surgeries for nasal, sinus and nasopharyngeal diseases need to be performed under nasal endoscopy. During nasal endoscopic surgery, bleeding in the surgical area often causes unclear surgical field of view, which may affect the progress of the operation at the least, or cause damage to important structures such as brain tissue and internal carotid artery at the worst, resulting in catastrophic consequences. Therefore, reliable hemostasis is very important during nasal endoscopic surgery.

[0003] At present, bipolar coagulation devices are commonly used for hemostasis in endoscopic nasal surgery. The bipolar coagulation device connects two electrodes to the two blades of a pair of tweezers, with an insulator between the two blades. After power is turned on, the current passes through the bipolar coagulation device between the two tips of the tweezers and is inserted into the nasal cavity for surgery.

[0004] However, the holding ends of the existing bipolar coagulators are easily opened and closed during use, so that medical staff are prone to mistakenly close the two bipolar coagulators during use, which poses certain safety hazards during use. In addition, when the bipolar coagulation uses a suction tube to absorb liquid from the patient's nasal hemostasis position, the suction tube is difficult to fully and completely extend into the position where the liquid accumulates, thereby reducing the effect and efficiency of liquid suction.

[0012] A method for using bipolar electrocoagulation for nasal hemostasis, comprising the following steps:

[0013] S1: First, the medical staff held the grip with the palm, placed the thumb on the button, and held the grip with the remaining four fingers;

[0014] S2: When it is necessary to aspirate the liquid gathered at the surgical site of the patient, the button can be pressed first to fit the grip. When the button is pressed, the push rod can be pushed to move horizontally to the left under the limiting action of the second limiting plate to overcome the resistance of the fifth spring. The push rod moves to the left to push the horizontal rack to move to the left synchronously, and drives the cylindrical gear to rotate. The rotation of the cylindrical gear drives the vertical rack to move vertically upward, thereby driving the locking block to disengage from between the two adjacent fixed blocks and fit with the bottom of the first blocking plate.

[0015] S3: Then, four fingers pull the grip to rotate toward the side close to the handle, the rotation of the grip drives the movable shaft to rotate, the rotation of the movable shaft drives the driving gear to rotate, the driving gear drives the rack to move horizontally to the left, when the leftmost fixed block fits with the right side of the second blocking plate, the button can be released to reset the locking block downward and insert it between the two fixed blocks on the right side, thereby locking the grip;

[0016] S4: When the rack is pushed to move to the left, the movable plate can be pushed to move horizontally to the left. The horizontal movement of the movable plate to the left drives the T-shaped rod to move to the left. The movement of the T-shaped rod to the left can push the suction tube to overcome the resistance of the first spring and move to the left, so that the suction tube protrudes from the left side of the two clamp heads. Then, when the medical staff inserts the suction tube into the surgical position of the patient, the liquid accumulated at the surgical position of the patient can be sucked out with the external suction device.

[0017] S5: When the collected liquid is sucked out, the gripping rod can be reset, and then the pull ring is pulled downward, which drives the pull rod downward, and drives the T-shaped rod downward to overcome the resistance of the third spring, thereby pulling the T-shaped rod to the bottom of the suction tube, so that when the suction tube is pushed to slide horizontally to the right, it can be retracted into the inner cavity of the clamp barrel, and the T-shaped rod is vertically limited;

[0018] S6: In addition, when the T-shaped rod moves vertically downward, the blocking plate can be driven to move downward synchronously. The blocking plate moves downward to seal the circular hole and fits with the right side wall of the second square rod;

[0019] S7: When the above operation is repeated and the gripping rod is pulled close to the gripping handle again, the movable plate can be used to move horizontally to the left and drive the blocking plate to move synchronously to the left. The blocking plate moving to the left can push the second square rod to overcome the resistance of the fourth spring and move to the left. The second square rod moving to the left can push the U-shaped plate to move to the left. The U-shaped plate moving to the left can push the two connecting blocks to move synchronously to the left. The connecting block moving to the left drives the hemispherical protrusion to move downward, thereby pushing the two extrusion plates to overcome the resistance of the adjacent second springs and move relative to each other. The relative movement of the two extrusion plates drives the two lifting blocks to move relative to each other, and drives the two connecting rods to move relative to each other. The relative movement of the two connecting rods can drive the two clamp heads to close, so that the electrodes on the two clamp heads can be used to clamp the wound for electrocoagulation hemostasis;

[0020] S8: After the bipolar electrocoagulation is used, the forceps head can be twisted to drive the screw to rotate, so that the screw can be screwed out of the threaded hole, and the forceps head can be disassembled for cleaning and disinfection.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is provided with a button, a push rod, a second limiting plate, a fifth spring, a transverse rack, a cylindrical gear, a rotating shaft, a vertical rack, a first limiting plate, a locking plate and a fixed block. When it is necessary to use a suction tube to suck out the liquid gathered at the surgical site, the button can be pressed and the locking block can be pulled out from between the two fixed blocks. Then, the grip rod is held with fingers and the grip is brought close to the handle. When the leftmost fixed block is fitted with the second blocking plate, the button can be released, so that the locking block falls between the two right fixed blocks and is locked. When the rack is pushed to move to the left, the movable plate can be pushed to move to the left, and the suction tube can be pushed to move horizontally to the left through the T-shaped rod, so that the suction tube protrudes to the left side of the two forceps heads, so that the surgeon can use the suction tube to suck away the liquid gathered around the surgical site, which not only improves the convenience of use by the surgeon, but also can fully suck out the gathered liquid, which is beneficial to improving the surgical treatment effect.

[0023] 2. The present invention pulls the pull ring and drives the pull rod to move downward. The downward movement of the pull rod can drive the T-shaped rod to overcome the resistance of the third spring and move downward. Then, the suction tube can be pushed to move horizontally to the right, and the suction tube can be retracted into the inner cavity of the clamp barrel. At the same time, the T-shaped rod is fitted with the bottom of the suction tube, and the blocking plate is fitted with the second square rod. When the grip rod is held again and the grip is close to the handle, the second square rod can be pushed to move horizontally to the left through the blocking plate, and the U-shaped plate can be driven to move horizontally to the left. The left movement of the U-shaped plate can push the two connecting blocks to move to the left, and drive the two hemispherical protrusions to push the two extrusion plates closer to each other. The two extrusion plates gather together and drive the two forceps heads to close through the two connecting rods, so as to achieve the effect of two electrodes clamping the wound for electrocoagulation and hemostasis. The surgeon can perform hemostasis operation on the bipolar electrocoagulation only when pressing the button, which improves the safety of the bipolar electrocoagulation when in use.

[0035] A method for using bipolar electrocoagulation for nasal hemostasis, comprising the following steps:

[0036] S1: First, the medical staff holds the grip 2 with the palm, places the thumb on the button 37, and holds the grip 3 with the remaining four fingers;

[0037] S2: When it is necessary to aspirate the liquid gathered at the surgical site of the patient, the button 37 can be pressed first to fit the grip 2. When the button 37 is pressed, the push rod 35 can be pushed to move horizontally to the left under the limiting action of the second limiting plate 36 to overcome the resistance of the fifth spring 38. The push rod 35 moves to the left to push the horizontal rack 34 to move to the left synchronously, and drives the cylindrical gear 32 to rotate. The rotation of the cylindrical gear 32 drives the vertical rack 30 to move vertically upward, thereby driving the locking block 29 to disengage from between the two adjacent fixing blocks 28 and fit with the bottom of the first blocking plate 39.

[0038] S3: Next, four fingers pull the grip 3 to rotate toward the side close to the grip 2, the rotation of the grip 3 drives the movable shaft 4 to rotate, the rotation of the movable shaft 4 drives the driving gear 5 to rotate, the driving gear 5 drives the push rack 6 to move horizontally to the left, when the leftmost fixed block 28 is in contact with the right side of the second blocking plate 40, the button 37 can be released, so that the locking block 29 is reset downward and inserted between the two right fixed blocks 28, thereby locking the grip 3;

[0039] S4: while pushing the rack 6 to move to the left, the movable plate 7 can be pushed to move horizontally to the left. The horizontal movement of the movable plate 7 to the left drives the T-shaped rod 8 to move to the left. The movement of the T-shaped rod 8 to the left can push the suction tube 9 to move to the left to overcome the resistance of the first spring 11, so that the suction tube 9 protrudes from the left side of the two forceps heads 20. Then, when the medical staff inserts the suction tube 9 at the surgical site of the patient, the liquid accumulated at the surgical site of the patient can be sucked out with the external suction device;

[0040] S5: When the collected liquid is sucked out, the gripping rod 3 can be reset, and then the pull ring 27 is pulled downward, which drives the pull rod 26 downward, and drives the T-shaped rod 8 to overcome the resistance of the third spring 23 and move downward, thereby pulling the T-shaped rod 8 to the bottom of the suction tube 9, so that when the suction tube 9 is pushed to slide horizontally to the right, it can be retracted into the inner cavity of the clamp barrel 1, and the T-shaped rod 8 is vertically limited;

[0041] S6: In addition, when the T-shaped rod 8 moves vertically downward, it can drive the blocking plate 24 to move downward synchronously. The blocking plate 24 moves downward to seal the circular hole 25 and fits with the right side wall of the second square rod 41;

[0042] S7: When the above operation is repeated to pull the gripping rod 3 close to the gripping handle 2 again, the movable plate 7 can be used to move horizontally to the left and drive the blocking plate 24 to move to the left synchronously. The blocking plate 24 moving to the left can push the second square rod 41 to overcome the resistance of the fourth spring 42 and move to the left. The second square rod 41 moving to the left can push the U-shaped plate 12 to move to the left. The U-shaped plate 12 moving to the left can push the two connecting blocks 13 to move to the left synchronously. The connecting block 13 moving to the left drives the hemispherical protrusion 14 to move downward, thereby pushing the two squeezing plates 15 to overcome the resistance of the adjacent second springs 22 and move relative to each other. The relative movement of the two squeezing plates 15 drives the two lifting blocks 16 to move relative to each other, and drives the two connecting rods 17 to move relative to each other. The relative movement of the two connecting rods 17 can drive the two clamp heads 20 to close, so that the electrodes on the two clamp heads 20 can be used to clamp the wound for electrocoagulation hemostasis;

[0043] S8: After the bipolar electrocoagulation is used, the clamp head 20 can be screwed to drive the screw 19 to rotate, so that the screw 19 can be screwed out of the threaded hole 18, and then the clamp head 20 can be disassembled, cleaned and disinfected.

[0044] Working principle: When the present invention is in use, first, the medical staff holds the handle 2 with the palm of their hand, puts the thumb on the button 37, and holds the grip 3 with the other four fingers, so that the medical staff can hold the bipolar electrocoagulation with one hand. When it is necessary to aspirate the liquid gathered at the surgical site of the patient, the button 37 can be pressed first to fit the handle 2. When the button 37 is pressed, the push rod 35 can be pushed to move horizontally to the left under the limiting action of the second limiting plate 36 to overcome the resistance of the fifth spring 38. The push rod 35 moves to the left to push the horizontal rack 34 to move to the left synchronously, and drives the cylindrical gear 32 to rotate. The rotation of the cylindrical gear 32 drives the vertical rack 30 to move vertically upward, thereby driving the locking block 29 to disengage from between the two adjacent fixed blocks 28 and engage with the first blocking plate 39. The bottom of the handle 2 is fitted, and then, four fingers pull the grip 3 to rotate toward the side close to the grip 2. The rotation of the grip 3 drives the movable shaft 4 to rotate, and the rotation of the movable shaft 4 drives the driving gear 5 to rotate. The driving gear 5 drives the rack 6 to move horizontally to the left. When the leftmost fixed block 28 fits with the right side of the second blocking plate 40, the button 37 can be released to make the locking block 29 reset downward and insert it between the two right fixed blocks 28, thereby locking the grip 3. While pushing the rack 6 to the left, the movable plate 7 can be pushed to move horizontally to the left. The horizontal movement of the movable plate 7 to the left drives the T-shaped rod 8 to move to the left. The movement of the T-shaped rod 8 to the left can push the suction tube 9 to overcome the resistance of the first spring 11 and move to the left, so that the suction tube 9 protrudes from the two pliers heads 20. On the left side, further, when the medical staff inserts the suction tube 9 at the patient's surgical position, the external suction device can be used to suck out the liquid accumulated at the patient's surgical position, which is beneficial to improving the quality and efficiency of the operation. When the accumulated liquid is sucked out, the grip rod 3 can be reset, and then the pull ring 27 is pulled downward. The downward movement of the pull ring 27 drives the pull rod 26 to move downward, and drives the T-shaped rod 8 to overcome the resistance of the third spring 23 and move downward, thereby pulling the T-shaped rod 8 to the bottom of the suction tube 9, so that when the suction tube 9 is pushed to slide horizontally to the right, it can be retracted into the inner cavity of the clamp barrel 1, and the T-shaped rod 8 can be vertically limited. In addition, when the T-shaped rod 8 moves vertically downward, it can drive the blocking plate 24 to move downward synchronously, and the downward movement of the blocking plate 24 can The circular hole 25 is sealed and fitted with the right side wall of the second square rod 41. When the above operation is repeated to pull the gripping rod 3 close to the gripping handle 2 again, the movable plate 7 can be used to move horizontally to the left and drive the blocking plate 24 to move to the left synchronously. The blocking plate 24 moves to the left and can push the second square rod 41 to overcome the resistance of the fourth spring 42 and move to the left. The second square rod 41 moves to the left and can push the U-shaped plate 12 to move to the left. The U-shaped plate 12 moves to the left and can push the two connecting blocks 13 to move to the left synchronously. The connecting block 13 moves to the left and drives the hemispherical protrusion 14 to move downward, so that the two extrusion plates 15 can be pushed to overcome the resistance of the adjacent second springs 22 and move relative to each other. The relative movement of the two extrusion plates 15 drives the two lifting blocks 16 to move relative to each other, and drives the two connecting rods 17 to move relative to each other.The relative movement of the two connecting rods 17 can drive the two clamp heads 20 to close, so that the electrodes on the two clamp heads 20 can be used to clamp the wound for electrocoagulation hemostasis. After the bipolar electrocoagulation is used, the clamp heads 20 can be twisted to drive the screw 19 to rotate, so that the screw 19 can be screwed out of the threaded hole 18, and then the clamp heads 20 can be disassembled for cleaning and disinfection. Through the setting of the button 37, when suction or electrocoagulation hemostasis is performed, the medical staff needs to actively press the button 37 before the surgical operation can be performed, which not only improves the safety of the bipolar electrocoagulation, but also can set liquid suction and electrocoagulation hemostasis together, thereby improving the functionality of the bipolar electrocoagulation.
