Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more specifically to an instrument for laparoscopic thoracic surgery. Background Art

[0002] Laparoscopic minimally invasive surgery is a type of surgery that is becoming more and more widely used. It has the advantages of high surgical efficiency and little damage to the human body. It speeds up the patient's recovery and reduces the patient's pain.

[0003] Electrocoagulation forceps are often used during surgery. High-frequency electrical energy is transmitted to both ends of the forceps. The current causes local heating of the tissue, thereby thermally coagulating the tissue and quickly cutting the tissue. The tip of the forceps is specially designed to concentrate the current and speed up the cutting and hemostasis, accurately control the cutting depth and shape, leave almost no scars, and have high safety and precision.

[0004] With existing electrocoagulation forceps, in order to prevent the open and closed forceps from scraping the patient's wound during the process of the forceps entering and exiting the patient's body, the doctor needs to press the handle to keep the forceps in a closed state. However, the doctor's fingers will become sore and the force will be unstable when controlling the opening and closing of the forceps during a long operation. When the doctor takes out the electrocoagulation forceps, the unstable force will easily cause the forceps to open and close and scrape the side wall of the wound, which can easily cause injury to the patient or even heavy bleeding, leading to serious medical accidents.

[0036] The fixing assembly includes a fixing hole 2121 provided on the mounting groove, a sliding groove provided on the mounting plate 210, a spring telescopic rod 2122 slidably installed in the sliding groove, and one end of the spring telescopic rod 2122 close to the fixing hole 2121 is an inclined surface, and a linkage assembly cooperating with the mounting plate 210 is provided on the second handle 208.

[0037] The linkage assembly includes an elastic airbag 301 fixedly mounted on the second handle 208, a linkage groove is provided on the mounting block 206, a linkage plate 302 fixedly connected to the spring telescopic rod 2122 is slidingly and sealably installed in the linkage groove, a connecting pipe 303 connected to the elastic airbag 301 is inserted on the linkage groove, and a first spring 304 is fixedly mounted between the side wall of the spring telescopic rod 2122 and the slide groove, a first limiting plate 305 is fixedly mounted on the inner wall of the main body tube 1, and the annular plate 203 is fixed on the side away from the first pliers 201. A second limit plate 306 is installed, and the second limit plate 306 is slidingly sealed with the inner wall of the main tube 1, a second spring 311 is fixedly installed between the first limit plate 305 and the second limit plate 306, a first push rod 307 is fixedly installed on the first pliers 201, a second push rod 308 is fixedly installed on the second pliers 202, a return spring 309 is fixedly installed between the first push rod 307 and the second push rod 308, and a groove 310 for pushing the first push rod 307 and the second push rod 308 is opened on the push plate 205.

[0038] In the initial state, the first spring 304 and the second spring 311 are evenly in a free extension state, that is, at this time, the first forceps 201 and the second forceps 202 are in a separated state, and the output end of the spring telescopic rod 2122 is located in the fixing hole 2121. When in use, the doctor can first press the second handle 208, and then the second handle 208 drives the mounting plate 210 to rotate through the linkage rod 209. During the rotation of the mounting plate 210, the connecting rope 211 is pulled, and then during the movement of the connecting rope 211, the doctor drives the mounting plate 210 to rotate. The push plate 205 moves, and during the movement of the push plate 205, a thrust is applied to the first push rod 307 and the second push rod 308 through the groove 310. Then, under the action of the thrust, the first push rod 307 and the second push rod 308 drive the first pliers 201 and the second pliers 202 to rotate. During the rotation of the first pliers 201 and the second pliers 202, the first pliers 201 and the second pliers 202 are closed. At this time, the second spring 311 is compressed and has a tendency to recover. At the same time, during the rotation of the mounting plate 210, the first pliers 201 and the second pliers 202 are closed. During the operation, the spring telescopic rod 2122 is driven to rotate. During the operation, the inclined surface of the spring telescopic rod 2122 gradually contacts the side wall of the fixing hole 2121. Then, under the action of the side wall of the fixing hole 2121, the output end of the spring telescopic rod 2122 contracts and has a tendency to recover. When the output end of the spring telescopic rod 2122 passes through the fixing hole 2121 again, the output end of the spring telescopic rod 2122 stretches and is inserted into the fixing hole 2121 again. Then, under the action of the fixing hole 2121 and the spring telescopic rod 2122, the mounting plate 210 cannot be reversed, so that the first pliers 201 and the second pliers 202 are always in a closed state. In other words, the first pliers 201 and the second pliers 202 can be kept in a closed state for a long time without the doctor pressing the second handle 208 for a long time, which effectively prevents the first pliers 201 and the second pliers 202 from opening and causing damage to the patient when the first pliers 201 and the second pliers 202 enter and exit the patient's body, thereby improving the safety of the patient.

[0039] After entering the patient's body, the doctor can first press the elastic airbag 301, and then the gas in the elastic airbag 301 is squeezed and flows into the linkage groove through the connecting pipe 303, and then the pressure in the linkage groove increases under the action of the gas, and under the action of the pressure, the linkage plate 302 drives the spring telescopic rod 2122 to move in the direction of the first spring 304 and disengage from the fixing hole 2121. At this time, the first spring 304 is squeezed, and the fixing effect of the mounting plate 210 is released. Then the doctor can freely rotate the second handle 208. When the doctor moves the first handle 207 and the second handle 208 away from each other, the connecting rope 211 is gradually in a relaxed state. At this time, the second spring 311 stretches and drives the first push rod 307 and the second push rod 308 to reverse. In the process of reversing the first push rod 307 and the second push rod 308, the first forceps 201 and the second forceps 208 are driven 02 is opened, and then the doctor can place the tissue that needs to be cut or coagulated between the first forceps 201 and the second forceps 202, and then the doctor can press the second handle 208 again and make the second handle 208 rotate toward the first handle 207. During the rotation of the second handle 208, the first forceps 201 and the second forceps 202 can be driven to merge again for cutting or coagulation. When the doctor feels tired due to pressing the second handle 208, the doctor can release the elastic airbag 301. At this time, the first spring 304 stretches and drives the output end of the spring telescopic rod 2122 to be inserted into the fixing hole 2121 again. At this time, the closed first forceps 201 and the second forceps 202 can be fixed, thereby effectively preventing the doctor from pressing the second handle 208 for a long time to cause hand fatigue, affecting the patient's surgical effect, and further improving the patient's safety.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the main tube 1 is provided with a first suction pipe 401 for absorbing smoke and blood, a second suction pipe 402 is fixedly mounted on the first suction pipe 401, a collecting box 403 for collecting smoke and blood is provided on the second suction pipe 402, a suction pump 404 is provided on the top wall of the collecting box 403, and an input end of the suction pump 404 is connected to the second suction pipe 402 through the collecting box 403.

[0041] A vertical groove is provided on the side wall of the installation groove, a pull rod 501 is slidably installed on the vertical groove, a limit plate 502 is fixedly installed on the pull rod 501 and slides with the vertical groove, a pull block 503 for driving the connecting rope 211 to move is rotatably installed on the pull rod 501, and a hole is provided on the pull block 503 and slides with the connecting rope 211.

[0042] The main body tube 1 is provided with a cavity 601 , in which a sealing plate 602 fixedly connected to the first suction tube 401 is slidably mounted, and the first limiting plate 305 is provided with a communication component matching the cavity 601 .

[0043] The connecting component includes a connecting block 6031 fixedly mounted on the first limiting plate 305, an air groove 6032 is opened on the connecting block 6031, a sealing block 6033 is slidably installed in the air groove 6032, a third spring 6034 is fixedly mounted between the side wall of the sealing block 6033 and the air groove 6032, a horizontal rod 6035 is fixedly mounted on the side wall of the sealing block 6033, a first air pipe 6036 connected to the cavity 601 is inserted on the side wall of the air groove 6032, and an exhaust valve 6037 is inserted in the cavity 601.

[0044] By adopting the above technical solution, when the doctor performs electrocoagulation surgery on the patient through the first forceps 201 and the second forceps 202, as the high-frequency electrical energy is transmitted to the two ends of the first forceps 201 and the second forceps 202, the patient's tissue is locally heated and thermally coagulated by the action of the current. During the thermal coagulation process, smoke is often generated, and the smoke is likely to affect the doctor's vision, thereby affecting the effect of the operation. Therefore, the smoke needs to be removed at this time. However, due to the small size of the minimally invasive hole, the smoke exhaust device cannot be inserted when the electrocoagulation forceps are inserted. Therefore, the doctor needs to remove the electrocoagulation forceps first, and then perform smoke exhaust. After the smoke exhaust is completed, the electrocoagulation forceps is inserted again. However, the back and forth insertion of the electrocoagulation forceps prolongs the operation time and is likely to cause damage to the patient's minimally invasive hole, thereby increasing the risk of the operation. When smoke exhaust is needed, the doctor can start the air pump, and then the air pump draws smoke from the patient's body through the filter box, the second suction tube 402, and the first suction tube 401, thereby further increasing the safety of the patient.

[0045] When the doctor cuts the patient's tissue, although the electric current can make the first forceps 201 and the second forceps 202 have the effect of accelerating cutting and stopping bleeding, blood will inevitably flow out during the cutting process, and the blood flowing out will easily cause the doctor's vision to be damaged. At this time, the doctor can make the first forceps 201 and the second forceps 202 in a closed state, and then pull the pull rod 501. During the movement of the pull rod 501, the connecting rope 211 is pulled to move through the pull block 503. During the movement of the connecting rope 211, the push plate 205 is driven to gradually contact the second limiting disk 306 and drive the second limiting disk 306 to move. At this time, the second spring 311 is compressed and has a tendency to recover. During the movement of the second limiting disk 306, the annular plate 203, The rotating rod 204 drives the first forceps 201 and the second forceps 202 to move into the main tube 1, and after the first forceps 201 enters the main tube 1, the pull rod 501 drives the limiting plate 502 to disengage from the mounting block 206. At this time, the doctor can rotate the pull rod 501 to drive the limiting plate 502 to rotate, and make the limiting plate 502 disengage from the vertical groove. Then, under the action of the limiting plate 502 and the side wall of the mounting block 206, the pull rod 501 is fixed, that is, the connecting rope 211 is fixed, so that the first forceps 201 and the second forceps 202 are fixed in the main tube 1. Then the doctor can aim the first suction tube 401 at the blood and start the suction pump 404 to clean the blood, thereby effectively preventing the blood from affecting the doctor's line of sight and further improving the safety of the patient.

[0046] In the process of the second limiting plate 306 moving toward the first limiting plate 305, the pressure between the first limiting plate 305 and the second limiting plate 306 increases, and then as the second limiting plate 306 moves, it gradually contacts the horizontal rod 6035 and applies a thrust to the horizontal rod 6035, and then the horizontal rod 6035 drives the sealing block 6033 to move under the action of the thrust, and squeezes the third spring 6034, and when the sealing block 6033 passes through the first air pipe 6036, the air flow in the space between the second limiting plate 306 and the first limiting plate 305 flows into the cavity 601 through the first air pipe 6036, and the pressure in the cavity 601 increases, and under the action of the pressure, the sealing plate 602 drives the first suction tube 401 to move outside the main tube 1, so that the first suction tube 401 extends out of the main tube 1, thereby facilitating the absorption of blood and further improving the blood cleaning effect.

[0047] When the blood is cleared, the doctor can rotate the pull rod 501 again, and make the pull rod 501 drive the limit plate 502 to contact the vertical groove. At this time, the second spring 311 stretches and drives the second limit plate 306 to reset. During the resetting of the second limit plate 306, the push plate 205, the connecting rope 211, and the pull block 503 drive the pull rod 501 to reset. At the same time, during the resetting of the second limit plate 306, the annular plate 203 and the rotating rod 204 drive the first forceps 201 and the second forceps 202 to extend out of the main tube 1. In addition, during the resetting of the second limit plate 306, the pressure between the second limit plate 306 and the first limit plate 305 is reduced, and air is sucked from the cavity 601 through the exhaust valve 6037. Then the pressure in the cavity 601 is reduced. Under the action of the pressure of the cavity 601, the sealing plate 602 drives the first suction tube 401 to reset, thereby preparing for work again.

[0048] like Figure 3 As shown, a pull ring 7 is fixedly mounted on one end of the pull rod 501 away from the pull block 503 .

[0049] By adopting the above technical solution, when the doctor pulls the pull rod 501, the doctor can drive the pull rod 501 to move through the pull ring 7, and can also rotate the pull rod 501 through the pull ring 7, which makes it easier for the doctor to drive the pull rod 501 to move.

[0050] like Figure 4 As shown, a latex pad 8 is fixedly installed on one end of the main body tube 1 close to the first pliers 201.

[0051] By adopting the above technical solution, when the main tube 1 enters the patient's body through the minimally invasive hole, a latex pad 8 is fixedly installed on one end of the main tube 1 close to the first forceps 201, which can prevent the side wall of the main tube 1 from scratching the patient when the main tube 1 enters the patient's body, thereby improving safety.

[0052] like Figure 7 As shown, the inclined surface of the spring telescopic rod 2122 is a smooth mirror surface.

[0053] By adopting the above technical solution, in the process that the fixing hole 2121 drives the output end of the spring telescopic rod 2122 to extend and retract back and forth, the side wall of the fixing hole 2121 and the inclined surface of the spring telescopic rod 2122 will rub against each other. By making the inclined surface of the spring telescopic rod 2122 a smooth mirror surface, the friction between the inclined surface of the spring telescopic rod 2122 and the fixing hole 2121 can be reduced, thereby ensuring that the fixing hole 2121 normally drives the output end of the spring telescopic rod 2122 to contract.

[0054] like Figure 3 As shown, a pulley 9 cooperating with the connecting rope 211 is rotatably mounted on the pulling block 503 .

[0055] By adopting the above technical solution, when the pulling block 503 drives the connecting rope 211 to move, the connecting rope 211 and the pulling block 503 will undergo relative displacement. By setting the pulley 9, the sliding friction between the connecting rope 211 and the pulling block 503 can be converted into rolling friction between the connecting rope 211 and the pulley 9, thereby reducing the wear of the connecting rope 211.

[0056] Instructions for use: During use, the doctor can first press the second handle 208, and then the second handle 208 drives the mounting plate 210 to rotate through the connecting rod 209. During the rotation of the mounting plate 210, the connecting rope 211 is pulled, and then the push plate 205 is driven to move during the movement of the connecting rope 211. During the movement of the push plate 205, a thrust is applied to the first push rod 307 and the second push rod 308 through the groove 310. Then, under the action of the thrust, the first push rod 307 and the second push rod 308 drive the first forceps 201 and the second forceps 202 to rotate. During the rotation of the first forceps 201 and the second forceps 202, the first forceps 201 and the second forceps 202 are closed. At the same time, during the rotation of the mounting plate 210, the spring telescopic rod 2122 is driven to rotate. During the rotation of the spring telescopic rod 2122, the inclined surface of the spring telescopic rod 2122 gradually contacts the side wall of the fixing hole 2121, and then the spring telescopic rod 2122 is extended under the action of the side wall of the fixing hole 2121. The output end of the retractable rod 2122 contracts and has a tendency to recover. When the output end of the spring telescopic rod 2122 passes through the fixing hole 2121 again, the output end of the spring telescopic rod 2122 stretches and is inserted into the fixing hole 2121 again. Then, under the action of the fixing hole 2121 and the spring telescopic rod 2122, the mounting plate 210 cannot be reversed. After entering the patient's body, the doctor can first press the elastic airbag 301, and then the gas in the elastic airbag 301 is squeezed and flows into the linkage groove through the connecting pipe 303. Then, under the action of the gas, the pressure in the linkage groove increases. Under the action of the pressure, the linkage plate 302 drives the spring telescopic rod 2122 to move in the direction of the first spring 304 and break away from the fixing hole 2121. At this time, the first spring 304 is squeezed, and the fixing effect of the mounting plate 210 is released. When smoke exhaust is needed, the doctor can start the air pump, and then the air pump absorbs smoke from the patient's body through the filter box, the second suction pipe 402, and the first suction pipe 401.

[0057] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
