Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a high-frequency biological tissue welding pliers capable of preventing smoke interference. Background Art

[0002] With the continuous advancement of medical technology, surgical suturing technology is also developing. Traditional electrosurgery requires manual control by the surgeon throughout the entire process, and a slight mistake may cause surgical accidents. Therefore, people began to explore methods to automatically control the output of electrosurgical equipment by measuring the state of the patient's surgical site to reduce the burden on clinical doctors and reduce the risk of surgical accidents. High-frequency biological tissue welding forceps use the heat energy generated by high-frequency current to promote the coagulation of protein molecules, thereby achieving tissue welding and effectively sealing the wound, thereby reducing the risk of infection.

[0003] In microsurgery, anastomosis of small blood vessels is a common operation. For delicate blood vessel welding, a spike-shaped welding head can be used. Its spike-shaped shape helps to accurately puncture and fit the blood vessel wall. Through appropriate energy transfer, the welding of the vascular endothelium is achieved, ensuring the patency of the blood vessel after anastomosis and reducing the risk of thrombosis. When the welding head penetrates the blood vessel wall, the blood vessel tissue will be squeezed and rubbed, causing the intima and middle layer of the blood vessel to adhere to the surface of the welding head. After welding, the patient's tissue will remain on the surface of the welding head. The remaining tissue will affect the performance of the welding head and the safety of the next use, interfere with the energy transfer in the next operation, and reduce the accuracy and effect of welding. In addition, when using biological tissue welding forceps, the smoke generated by the high temperature of the tissue will diffuse around the surgical area, blocking the medical staff's vision, thereby affecting the medical staff's operating accuracy and increasing the risk of surgery.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The support plate is extended out of the moving cylinder by the movement of the moving cylinder, and the magnetic force of the magnet block is used to make the sponge plate on the inclined plate fit with the side wall of the welding head. Then the cleaning plate is moved along the cleaning cylinder to make the spiral shaft slide along the spiral groove, and then the cleaning plate drives the rotating rod and the welding head to rotate through the clamping rod. At this time, the side wall of the welding head is fully in contact with the sponge plate, and the sponge plate is used to wipe the vascular intima and middle layer tissue remaining on the surface of the welding head, which ensures the performance of the welding head and the safety of the next use, avoids the tissue remaining on the welding head from interfering with the energy transfer of the welding head when it is used next time, and improves the welding accuracy and welding effect. At the same time, the smoking rod is used to extract the smoke generated during the welding process to prevent the smoke from obstructing the operator's sight, improve the welding accuracy, and reduce the risk of surgery; 2. The inclined plate is driven to move by the support plate, and then the two magnet blocks attract each other, causing the angle of the inclined plate to deflect. The inclined plate pulls the connecting rod, so that the support plate drives the chamfering block 1 to contact the chamfering block 2 and push the chamfering block 2. The flow slot 1 overlaps with the flow slot 2, and the physiological saline in the moving cylinder leaks out. The leaked physiological saline wets the sponge plate and the welding head. The physiological saline is used to wet the tissue remaining on the welding head, making it easier to separate the tissue from the welding head, thereby improving the cleaning effect of the sponge plate on the welding head; 3. After welding is completed, the clamp body is repeatedly retracted and expanded, so that the drainage column passes the gas entering the drainage cavity into the liquid storage box, and the gas enters the moving cylinder through the guide hole, so that the pressure in the moving cylinder is increased, and the physiological saline in the moving cylinder is quickly discharged from the moving cylinder under the action of pressure, which improves the contact efficiency between the physiological saline and the sponge plate and the welding head, thereby improving the cleaning efficiency and effect of the residual tissue on the surface of the welding head; 4. By setting up the discharge of physiological saline from the water outlet pipe, the patient's affected tissue is cleaned with physiological saline, while keeping the affected tissue moist, thus avoiding tissue drying and damage; 5. By setting up a smoking rod and using a negative pressure suction device, during the tissue welding process, the protein and fat in the tissue are affected by the high temperature and the smoke is sucked into the smoking rod under the influence of negative pressure, so that the surface smoke interferes with the operator's vision, thereby improving the welding accuracy and welding effect.

[0034] The liquid storage box 29 is provided with an air pressure block 295, a rack arranged in the air pressure block 295, a docking sleeve 296 arranged on the air pressure block 295, an air pressure cavity arranged in the air pressure block 295, a piston cavity arranged in the air pressure block 295, the air pressure cavity is connected with the inside of the piston cavity, the air pressure cavity is connected with the inside of the air pressure groove 293, the rack is slidably arranged in the piston cavity, the end of the rack away from the piston cavity is inserted into the docking sleeve 296 on another air pressure block 295, the end of the opening and closing plate 292 away from the opening and closing cylinder 291 is provided with a gear, the gear is arranged between the two racks, and the gear is meshed with the two racks respectively, the end of the opening and closing cylinder 291 away from the liquid storage box 29 is connected with a water inlet pipe, the water inlet pipe is connected to the peristaltic pump, the peristaltic pump is connected to a water tank through a water pipe, the water tank is filled with physiological saline, and the peristaltic pump can introduce the physiological saline in the water tank into the liquid storage box 29.

[0035] During use, first turn on the power supply and start the peristaltic pump and the negative pressure suction device. At this time, current flows through the welding head 11. The operator first pushes the shift block 221 to make the shift block 221 slide along the key slot 1 and move toward the welding head 11. Then, the clamping block 2 on the shift block 221 is engaged with the clamping block 1 near one end of the welding head 11. At this time, the moving cylinder 24 and the rotating rod 25 will drive the welding head 11 to shift synchronously and extend out of the housing 21. Then the operator brings the welding heads 11 on the two forceps 1 into contact with the tissue of the patient's affected area to be welded, and manually squeezes the handle of the forceps to make the two welding heads 11 approach each other, so that the patient's wound is closed by the squeezing force, and at the same time the current on the welding head 11 passes through the patient's tissue. When the current passes through the patient's tissue, heat is generated to destroy the cell membrane in the tissue at the patient's wound and release protein. The protein denatures, entangles and agglutinates under the action of high temperature, so that the wound interface is connected. During the tissue welding process, the protein and fat in the tissue generate smoke due to the high temperature. The negative pressure suction device generates negative pressure at the smoking hole area of ​​the smoking rod 22 close to one end of the welding head 11, so that the smoke generated during welding enters the smoking hole under the attraction of the negative pressure, and the smoke is finally collected into the storage tank through the smoking pipe; Furthermore, the cleaning plate 281 moves toward the welding head 11 under the elastic force of the second spring, and then the cleaning plate 281 pulls the piston plate 283 through the piston rod 282, so that the piston plate 283 presses the trigger rod 294, causing the spring three to deform, and then the trigger rod 294 contracts into the air pressure groove 293. At this time, the gas pressure in the air pressure groove 293 increases, and the rack in the air pressure block 295 is pushed out under the action of the gas pressure. The displacement of the rack will drive the gear and the opening and closing plate 292 to rotate. At this time, the water outlet groove 1 will overlap with the water outlet groove 2, and the physiological saline in the water tank is introduced into the liquid storage box 29 under the action of the peristaltic pump; As the peristaltic pump runs, the saline in the water tank will enter the moving cylinder 24 through the guide hole 286, and then the saline can enter the water outlet pipe through the moving groove. By adjusting the bamboo tube 241, the saline can drip out from the end of the water outlet pipe away from the moving groove and contact the welding head 11 and the patient's tissue, thereby preventing the welding head 11 and the patient's tissue from being adhered to each other due to the high temperature during the welding process. After the patient tissue welding is completed, the shift block 221 is manually pushed to disengage the second block on the shift block 221 close to the welding head 11 from the first block on the housing 21 close to the welding head 11, and then the shift block 221 is pushed to slide along the key slot 1 in a direction away from the welding head 11 until the second block on the shift block 221 away from the welding head 11 is engaged with the first block on the housing 21 away from the welding head 11, and the welding head 11 is retracted into the housing 21 again; During the movement of the shift block 221, the moving cylinder 24 will move synchronously with the shift block 221, and the engaging rod 284 will go deep into the water outlet groove, causing the water outlet frame 285 to contact the line plate 253 and force the spring four to deform. At this time, the retaining ring 254 will shift to the blocking moving groove, and the physiological saline in the moving cylinder 24 will no longer enter the water outlet pipe. At the same time, the locking rod 255 will drive the locking ring 256 to shift synchronously. During the shifting process of the locking ring 256, the locking tongue 257 will be moved, causing the locking tongue 257 to rotate and push the rotating ring 251. When the locking tongue 257 rotates to the limit position, the rotating ring 251 will separate from the locking tongue 257. The spring one is in a stretched state at this time, and then the mounting ring 26 is driven to rotate and move toward the direction of the welding head 11 under the action of the reset elastic force of the spring one. As the mounting ring 26 is displaced, the support rod gradually extends out of the moving cylinder 24, and the two magnet blocks 232 approach each other under the action of magnetic force, and the inclined plate 271 is offset relative to the support plate 27 and fits with the outer side wall of the welding head 11; As the shifting block 221 is pushed further, the rotating rod 25 and the moving cylinder 24 contact and push the cleaning plate 281. At this time, the spiral shaft slides along the spiral groove, the cleaning plate 281 rotates, and the engaging rod 284, the rotating rod 25 and the welding head 11 rotate synchronously. At this time, the sponge plate will wipe and clean the residual tissue and dirt on the outer side wall of the welding head 11. At the same time, when the cleaning plate 281 rotates, it will move in the direction away from the welding head 11, and the piston rod 282 and the piston plate 283 will move synchronously with it, causing the piston plate 283 to gradually separate from the trigger rod 294. The trigger rod 294 extends out of the air pressure groove 293 under the action of the restoring elastic force of spring 2. At this time, negative pressure is generated in the air pressure groove 293, and the rack shrinks into the air pressure groove 293 due to the negative pressure. During the movement of the rack, the driving gear and the opening and closing plate 292 rotate, causing the water outlet groove 1 and the water outlet groove 2 to be misaligned. At this time, the physiological saline cannot enter the liquid storage box 29. Example 2

During welding, the flow groove 1 35 and the flow groove 2 38 are in a mutually displaced positional relationship, and the positions of the chamfered block 1 33 and the chamfered block 2 37 correspond to each other. A spring 5 is provided in the annular groove 34, one end of the spring 5 is connected to the side wall of the annular groove 34, and the other end thereof is connected to the ring plate 36.

[0038] During use, when the support plate 27 extends out of the moving cylinder 24, the two magnet blocks 232 approach each other, and the angle of the inclined plate 271 relative to the support plate 27 is deflected. At this time, the inclined plate 271 will slide down along the slide groove toward the direction of the welding head 11, and then the inclined plate 271 will pull the support plate 32, so that the chamfered block 1 33 on the support plate 32 contacts the chamfered block 2 37 and forces the ring plate 36 to shift. At this time, the spring five is deformed, and then the flow groove 1 35 and the flow groove 2 38 coincide with each other. At this time, the physiological saline can pass through the flow groove 1 35 and the flow groove 2 38 and contact the sponge plate and the welding head 11 on the inclined plate 271, and then use the fluidity of the physiological saline to take away the residual tissue on the surface of the welding head 11, while improving the cleaning effect of the sponge plate on the welding head 11.

[0039] The remaining structures are the same as those of Example 1. Example 3

[0040] Reference Figure 1-Figure 10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: The drainage component 4 includes a drainage cylinder 41, a partition 42 arranged in the drainage cylinder 41, a one-way plate 1 43 arranged on the partition 42, a drainage column 44 arranged on the drainage cylinder 41, and a one-way plate 2 45 arranged on the drainage column 44. The drainage cylinder 41 is hingedly matched with the side wall of the liquid storage box 29 on one supporting clamp 1, and the drainage column 44 is hingedly arranged on the side wall of the liquid storage box 29 on the other supporting clamp 1. The end of the drainage column 44 away from the liquid storage box 29 is slidably arranged in the drainage cylinder 41; One end of the drain cylinder 41 away from the partition 42 and the drain column 44 is connected to a manifold, and one end of the manifold away from the drain cylinder 41 is respectively connected to the liquid storage boxes 29 on the two support clamps 1, and the drain cylinder 41 is connected to the inside of the liquid storage box 29 through the manifold; The partition 42 is arranged inside the drainage cylinder 41, and an air inlet hole 1 is opened on the partition 42. A one-way plate 1 43 is hingedly arranged on a side of the partition 42 away from the drainage column 44, and a torsion spring 1 is arranged at the connection between the one-way plate 1 43 and the partition 42; The second one-way plate 45 is hingedly arranged at one end of the drainage column 44 close to the partition plate 42 , and a second torsion spring is arranged at the connection between the second one-way plate 45 and the drainage column 44 , and a second air inlet hole is opened in the drainage column 44 .

[0041] During use, when the peristaltic pump is started, the welding head 11 extends out of the housing 21, and the clamp body has not yet clamped the patient's tissue, the two welding heads 11 are in a positional relationship away from each other, and the one-way plate 1 43 blocks the air inlet hole 1 under the elastic force of the torsion spring 1, and the one-way plate 2 45 blocks the air inlet hole 2 under the elastic force of the torsion spring 2. Since the gas in the drain cylinder 41 cannot communicate with the outside world, the saline entering the liquid storage box 29 from the water tank will not enter the drain cylinder 41 through the manifold under the action of the gas pressure; When welding the patient's tissue, by driving the two welding heads 11 to approach each other, the drainage column 44 moves synchronously toward the drainage cylinder 41. At this time, the one-way plate 43 opens under the action of gas pressure, and the gas passes through the partition 42 and enters the liquid storage box 29 through the manifold. At this time, the pressure in the liquid storage box 29 increases, and the end of the water outlet pipe away from the moving cylinder 24 will quickly discharge a certain amount of physiological saline, thereby moistening the patient's tissue and the welding head 11. At the same time, when the drainage column 44 moves to the limit position, the one-way plate 43 will be reset under the reset elastic force of the torsion spring 1, and the air inlet hole 1 is blocked by the one-way plate 43; When the tissue welding is completed, the shifting block 221 is shifted to make the welding head 11 retract into the movable cylinder 24. At this time, the physiological saline in the liquid storage box 29 is pushed into the movable cylinder 24 by the piston plate 283, and the two supporting forceps 1 are driven to perform reciprocating movement. When the drain column 44 gradually moves away from the drain cylinder 41, negative pressure is generated between the drain column 44 and the partition 42, the one-way plate 1 43 fits tightly with the partition 42, the air inlet 1 is blocked, and at the same time, the one-way plate 2 45 rotates under the attraction of negative pressure, so that the one-way plate 2 45 no longer blocks the air inlet 2, the air inlet 2 is opened, and the inside of the drain cylinder 41 is connected with the outside world. When the drain column 44 moves, the outside gas enters the cavity between the drain cylinder 41 and the partition 42 through the air inlet 2. When the drain column 44 moves to the limit position, the negative pressure between the drain column 44 and the partition 42 is reduced, and the one-way plate 2 45 is reset under the reset elastic force of the torsion spring 2. When the drainage column 44 gradually approaches the drainage cylinder 41, the gas between the partition 42 and the drainage column 44 is pressurized and pushes the one-way plate 43, so that the air inlet hole 1 is opened, and the gas is pressed into the liquid storage box 29 through the air inlet hole 1, and then enters the moving cylinder 24 through the liquid storage box 29. At this time, the pressure in the moving cylinder 24 increases, and the physiological saline entering the moving cylinder 24 is quickly discharged from the moving cylinder 24 under the action of pressure. When the drainage column 44 moves to the limit position, the gas pressure between the partition 42 and the drainage column 44 decreases, and the one-way plate 43 is reset under the elastic force of the torsion spring 1.

[0042] The remaining structure is the same as that of Example 2.
