Description

Technical Field

[0001] The present invention relates to the technical field of surgical medical devices, and particularly to a blood vessel clamp for surgical operations and its usage method. Background Art

[0002] Vascular surgery is responsible for treating diseases occurring in blood vessels throughout the circulatory system except for the heart and intracranial vessels. Peripheral vascular diseases are general terms for peripheral vascular diseases. According to the different types of blood vessels involved, they can be classified into arterial diseases and venous diseases; according to the different types of lesions, they can be divided into obstructive diseases and dilative diseases. It mainly includes arteriosclerosis obliterans, acute arterial embolism, abdominal aortic aneurysm, thoracic aortic aneurysm, aortic dissection, varicose veins of the lower extremities, incompetence of deep vein valves in the lower extremities, thromboangiitis obliterans, deep vein thrombosis in the lower extremities, iliac vein compression syndrome, portal hypertension, etc.

[0003] Currently, the common and harmful disease in clinical practice is arteriosclerosis obliterans, and the lesions are mostly seen in blood vessels such as the lower extremity arteries, carotid arteries, subclavian arteries, renal arteries, and superior mesenteric arteries. Aortic dissection, thoracic aortic aneurysm, and abdominal aortic aneurysm are the most harmful peripheral vascular diseases in clinical practice. The main risk is death caused by blood vessel rupture. During the surgical treatment process, in order to avoid bleeding in the blood vessels, a clamp is used to clamp the blood vessels, thereby blocking the blood flow in the blood vessels. When using a traditional blood vessel clamp, continuous force needs to be applied by hand, which is inconvenient to operate and affects the progress of the operation. Moreover, it is difficult to master the applied force, which is likely to cause excessive compression of the blood vessels and cause secondary damage to them. Moreover, when clamping multiple blood vessels, multiple clamps need to be used in cooperation with medical staff for operation, which is extremely inconvenient and likely to interfere with the operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a blood vessel clamp for surgical operations and its usage method, so as to solve the problems mentioned in the above background art that when using a traditional blood vessel clamp, continuous force needs to be applied by hand, which is inconvenient to operate and affects the progress of the operation, and it is difficult to master the applied force, which is likely to cause excessive compression of the blood vessels and cause secondary damage to them. Moreover, when clamping multiple blood vessels, multiple clamps need to be used in cooperation with medical staff for operation, which is extremely inconvenient and likely to interfere with the operation.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A vascular clamp for surgical operations, comprising a pressure boosting cylinder. A turnover cylinder is fixedly installed at the bottom of the pressure boosting cylinder, and the turnover cylinder is communicated with the bottom of the pressure boosting cylinder. A plurality of diversion components are equidistantly connected to the bottom of the turnover cylinder. One end of the diversion component away from the turnover cylinder is communicated with an air cylinder. One side of the air cylinder away from the diversion component is fixedly connected with a housing. A deflection component is installed inside the housing. One end of the deflection component away from the housing is provided with a clamping component. One end of the deflection component away from the clamping component is lapped with an adjusting component. The adjusting component penetrates through one side of the housing and is slidably connected inside the air cylinder. A pressure boosting component is movably installed inside the pressure boosting cylinder, and the top end of the pressure boosting component penetrates through the top of the pressure boosting cylinder. Two baffle plates are respectively fixedly connected to both sides of the outer wall of the pressure boosting cylinder. A check valve II is installed at the bottom of the pressure boosting cylinder. The pressure boosting cylinder is communicated with the turnover cylinder through the check valve II. A plurality of check valves I are equidistantly installed at the edge of the bottom of the pressure boosting cylinder.

[0007] As a further scheme of the present invention, a cover plate is installed on the top of the housing. Two limiting columns are fixedly connected to one side of the housing. Position-limiting holes are opened at the bottom of the cover plate corresponding to the positions of the limiting columns. The limiting columns are inserted into the position-limiting holes. Two bolts are threadedly connected to the cover plate. The cover plate is installed on the housing through the two bolts.

[0008] As a further scheme of the present invention, the diversion component includes a trachea. The top end of the trachea is communicated with the bottom of the turnover cylinder, and a stop valve is installed between the trachea and the turnover cylinder. An exhaust valve is arranged below the stop valve. The exhaust valve is installed outside the trachea. The bottom end of the trachea is communicated with one side of the air cylinder.

[0009] As a further scheme of the present invention, the deflection component includes two clamping arms. A pin is rotatably connected to the middle of the clamping arm. Both ends of the pin are movably connected to the opposite surfaces of the housing and the cover plate. Installation grooves are respectively opened on the opposite surfaces of the two clamping arms. A first spring is installed between the two installation grooves. One end of the two clamping arms close to each other is lapped with the end of the adjusting component, and one end of the two clamping arms away from each other is connected with the clamping component.

[0010] As a further scheme of the present invention, the clamping component includes a clamping plate. A hinge seat is fixedly connected to one side of the clamping plate close to the clamping arm. The end of the clamping arm is hinged to the clamping plate through the hinge seat. Anti-slip lines are arranged on the side of the clamping plate away from the hinge seat, and a pressure sensor is installed in the middle of the clamping plate. The output end of the pressure sensor is connected with a monitor through a signal line. The monitor is clamped in the empty groove opened at the end of the clamping arm. The monitor is used for receiving the pressure data fed back after the pressure sensor is pressed.

[0011] As a further solution of the present invention, the adjusting assembly includes a sliding column. One end of the sliding column penetrates and slides in the shell and is fixedly connected to a top block. The top block is located inside the shell. Both sides of the top block are designed to be inclined and are lapped with one end of the two clamping arms close to each other. The end of the sliding column away from the top block is fixedly connected to a piston seat. The piston seat is slidably connected in the air cylinder. A second spring is sleeved outside the sliding column. The two ends of the second spring are respectively fixedly connected to the piston seat and one side of the inner wall of the air cylinder.

[0012] As a further solution of the present invention, the pressurizing assembly includes a sliding rod. The top end of the sliding rod penetrates the pressurizing cylinder and is fixedly connected to a pressing plate. The end of the sliding rod away from the pressing plate is fixedly connected to a piston plate. The piston plate is slidably connected inside the pressurizing cylinder. A third spring is sleeved outside the sliding rod. The top end of the third spring is fixed to the top of the inner wall of the pressurizing cylinder, and the bottom end of the third spring is fixed on the piston plate.

[0013] A method for using a blood vessel clamp for surgical operations, the method comprising the following steps:

[0014] When using the blood vessel clamp, during the process of clamping a blood vessel at a specified position, move the deflection assembly in the shell to the position of the blood vessel, so that the two clamping assemblies on the deflection assembly are located on both sides of the blood vessel to be clamped. Place the fingers under the two baffles outside the pressurizing cylinder, and push the pressing plate downward with the thumb, so that the pressing plate drives the piston plate to move downward through the sliding rod, so that the gas inside the pressurizing cylinder enters the turnover cylinder through the check valve II. The check valve II is used to introduce the gas inside the pressurizing cylinder into the turnover cylinder and can prevent the gas inside the turnover cylinder from flowing back into the pressurizing cylinder through the check valve II. When the piston plate stops moving downward, release the pressing plate, and support the piston plate by the elastic force of the third spring, so that the piston plate can move upward inside the pressurizing cylinder. The check valve I is used to introduce gas into the pressurizing cylinder and can prevent the gas inside the pressurizing cylinder from being discharged through the check valve I. When the pressing plate is pushed downward again, the extracted gas can be re-introduced into the turnover cylinder through the check valve II, so as to continuously supply air into the turnover cylinder;

[0015] At this time, the stop valve is in the open state and the exhaust valve is in the closed state. The gas inside the turnover cylinder enters the air cylinder through the stop valve and the air guide pipe. As the pressure inside the air cylinder increases, it pushes the piston seat to move inside the air cylinder. The piston seat drives the top block to move inside the housing through the sliding column, enabling the top block to squeeze the ends of the two clamping arms that are approaching each other. Due to the inclined design on both sides of the top block, the top block can push the ends of the two clamping arms away from each other, causing the clamping arms to rotate around the pin in the middle, so that the other ends of the two clamping arms drive the two clamping components to approach each other respectively, making the clamping plates in the clamping components contact the blood vessel. As the clamping arms continue to rotate, the two clamping plates can clamp the blood vessel to block the blood flow on both sides inside the blood vessel. During the process of the clamping plates squeezing the blood vessel, the force between the two clamping plates causes the clamping plates to drive the hinge seat to rotate at the end of the clamping arm, enabling the two clamping plates to adaptively adjust the angle and making the two clamping plates in a parallel state. With the anti-slip pattern provided on one side of the clamping plate, the stability of the clamping of the blood vessel by the clamping plate is improved;

[0016] During the process of the clamping plates clamping the blood vessel, the pressure sensor inside the clamping plate can monitor the clamping force on the blood vessel. Since the output end of the pressure sensor is connected to the monitor through a signal wire, the monitor can receive the pressure data fed back after the pressure sensor is pressed, so as to facilitate grasping the clamping force on the blood vessel. When the clamping force is too large, by opening the exhaust valve outside the air guide pipe, the piston seat is squeezed by the elastic force of the second spring, enabling the piston seat to move inside the air cylinder and drive the top block to gradually move away from the ends of the two clamping arms. At the same time, the elastic force of the first spring can support the two clamping arms, causing the clamping plates at the ends of the clamping arms to move away from each other. The gas inside the air cylinder passes through the air guide pipe and is discharged from the exhaust valve. At the same time, the other end of the clamping arm drives the clamping plate to gradually move away from the blood vessel through the hinge seat, thereby reducing the clamping force of the clamping plate on the blood vessel and avoiding secondary damage to the blood vessel caused by excessive compression of the blood vessel by the clamping plate. When the top block no longer squeezes the two clamping arms, the clamping plates at the ends of the two clamping arms can move away from the blood vessel, thereby facilitating the release of the clamping state of the blood vessel;

[0017] When clamping multiple blood vessels, open the stop valves outside multiple air ducts so that the gas inside the turnover cylinder can enter multiple air ducts simultaneously. The gas is then sent into the air cylinder by the air ducts to squeeze the piston seat. When the piston seat pushes the top block to move through the sliding column, the ends of the two clamping arms can drive the clamping assembly to clamp the blood vessels, enabling multiple deflection assemblies to work synchronously, thereby achieving the purpose of synchronously clamping multiple blood vessels. Moreover, the check valve II can prevent the gas from flowing back into the pressurizing cylinder. Even if the pressurizing assembly is not operated, the clamping assembly can always maintain the corresponding clamping force, which is convenient for controlling the force applied to the blood vessels. When adjusting the clamping force of different blood vessels, one or several exhaust valves outside the air ducts can be opened, allowing the gas inside the air cylinder to pass through the air ducts and be discharged from the exhaust valves, enabling the adjustment of the position of the top block, and thus facilitating the adjustment of the clamping force of the blood vessels. When one or several stop valves are closed, the gas will no longer enter the air ducts. Additionally, the exhaust valves and stop valves outside multiple air ducts are independently designed, which can facilitate the independent adjustment of the clamping or loosening of different blood vessels.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When clamping multiple blood vessels, the present invention opens the stop valves outside multiple air ducts, enabling the gas inside the turnover cylinder to enter multiple air ducts simultaneously. The gas is then sent into the air cylinder by the air ducts to squeeze the piston seat. When the piston seat pushes the top block to move through the sliding column, the ends of the two clamping arms can drive the clamping assembly to clamp the blood vessels, enabling multiple deflection assemblies to work synchronously, thereby achieving the purpose of synchronously clamping multiple blood vessels. Moreover, the check valve II can prevent the gas from flowing back into the pressurizing cylinder. Even if the pressurizing assembly is not operated, the clamping assembly can always maintain the corresponding clamping force, which is convenient for controlling the force applied to the blood vessels. When adjusting the clamping force of different blood vessels, one or several exhaust valves outside the air ducts can be opened, allowing the gas inside the air cylinder to pass through the air ducts and be discharged from the exhaust valves, enabling the adjustment of the position of the top block, and thus facilitating the adjustment of the clamping force of the blood vessels. When one or several stop valves are closed, the gas will no longer enter the air ducts. Additionally, the exhaust valves and stop valves outside multiple air ducts are independently designed, which can facilitate the independent adjustment of the clamping or loosening of different blood vessels, abandoning the traditional method of using multiple clamping forceps in cooperation with medical staff for operation. It is not only convenient to operate but also not likely to interfere with the operation.

[0020] 2. During the process of clamping the blood vessel by the splint in the present invention, the pressure sensor inside the splint can monitor the clamping force on the blood vessel. Since the output end of the pressure sensor is connected to the monitor through a signal line, the monitor can receive the pressure data fed back after the pressure sensor is pressed, so as to master the clamping force on the blood vessel. When the clamping force is too large, by opening the exhaust valve outside the air duct, the piston seat is extruded by the elastic force of the second spring, so that the piston seat can move inside the air cylinder and drive the top block to gradually move away from the ends of the two clamping arms. At the same time, the elastic force of the first spring can support the two clamping arms, so that the splints at the ends of the clamping arms can move away from each other. The gas inside the air cylinder passes through the air duct and is discharged from the exhaust valve. At the same time, the other end of the clamping arm drives the splint to gradually move away from the blood vessel through the hinge seat, thereby reducing the clamping force of the splint on the blood vessel and avoiding secondary damage to the blood vessel caused by excessive compression of the splint on the blood vessel. When the top block no longer presses the two clamping arms, the splints at the ends of the two clamping arms can move away from the blood vessel, thereby facilitating the release of the clamping state of the blood vessel.

[0021] 3. When pressurizing the inside of the air cylinder through the air duct in the present invention, the air pressure will push the piston seat to move inside the air cylinder. The piston seat drives the top block to move inside the housing through the sliding column, so that the top block can squeeze one end of the two clamping arms that are close to each other. Since the two sides of the top block are inclined, the top block can push the ends of the two clamping arms away from each other, so that the clamping arms can rotate around the pin in the middle, and the other ends of the two clamping arms drive the two clamping components to approach each other respectively, so that the splints in the clamping components come into contact with the blood vessel. As the clamping arms continue to rotate, the two splints can clamp the blood vessel to block the blood flow on both sides inside the blood vessel. During the process of the splint squeezing the blood vessel, the force between the two splints enables the splint to drive the hinge seat to rotate at the end of the clamping arm, so that the two splints can adaptively adjust the angle and the two splints are in a parallel state. With the anti-slip pattern provided on one side of the splint, the stability of the splint clamping the blood vessel is improved.

[0022] 4. By pushing down the pressing plate in the present invention, the pressing plate drives the piston plate to move downward through the sliding rod, so that the gas inside the pressurizing cylinder enters the turnover cylinder through the check valve II. The check valve II is used to introduce the gas inside the pressurizing cylinder into the turnover cylinder and can block the gas inside the turnover cylinder from flowing back to the pressurizing cylinder through the check valve II. When the piston plate no longer moves downward, release the pressing plate, and the piston plate is supported by the elastic force of the third spring, so that the piston plate can move upward inside the pressurizing cylinder. The check valve I is used to introduce the gas into the pressurizing cylinder and can block the gas inside the pressurizing cylinder from being discharged through the check valve I. When the pressing plate is pushed downward again, the extracted gas can be re-introduced into the turnover cylinder through the check valve II to continuously ventilate the turnover cylinder.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0036] A vascular clamp for surgical operations, including a pressurizing cylinder 1. A turnover cylinder 2 is fixedly installed at the bottom of the pressurizing cylinder 1, and the turnover cylinder 2 is communicated with the bottom of the pressurizing cylinder 1. A plurality of flow guiding components 3 are equidistantly connected to the bottom of the turnover cylinder 2. The flow guiding component 3 includes an air guide pipe 301. The top end of the air guide pipe 301 is communicated with the bottom of the turnover cylinder 2, and a stop valve 302 is installed between the air guide pipe 301 and the turnover cylinder 2. An exhaust valve 303 is arranged below the stop valve 302. The exhaust valve 303 is installed outside the air guide pipe 301. The bottom end of the air guide pipe 301 is communicated with one side of an air cylinder 4.

[0037] When the stop valve 302 is in an open state and the exhaust valve 303 is in a closed state, the gas inside the turnover cylinder 2 can enter the air cylinder 4 through the stop valve 302 and the air guide pipe 301, achieving the purpose of connecting the turnover cylinder 2 and the air cylinder 4; when the exhaust valve 303 is opened, the gas inside the air cylinder 4 passes through the air guide pipe 301 and is discharged from the exhaust valve 303, thereby releasing the pressure.

[0038] One side of the air cylinder 4 away from the flow guiding component 3 is fixedly connected to a housing 5. A cover plate 6 is installed on the top of the housing 5. Two limiting columns 7 are fixedly connected to one side of the housing 5. Limiting holes 8 are opened at the positions corresponding to the limiting columns 7 at the bottom of the cover plate 6. The limiting columns 7 are inserted into the limiting holes 8. Two bolts 9 are threadedly connected to the cover plate 6. The cover plate 6 is installed on the housing 5 through the two bolts 9. When separating the housing 5 and the cover plate 6, by loosening the two bolts 9 on the cover plate 6 to make the bolts 9 disengage from the housing 5, the locking state between the housing 5 and the cover plate 6 can be released, so as to remove the cover plate 6, achieving the purpose of maintaining or replacing the internal structure of the housing 5. When installing the cover plate 6, the two limiting holes 8 on the cover plate 6 are aligned with the limiting columns 7 and sleeved, and fixed through the bolts 9. The cover plate 6 is limited by the limiting columns 7, thereby improving the installation stability of the cover plate 6 and the housing 5.

[0039] Inside the housing 5, a deflection assembly 10 is installed. The deflection assembly 10 includes two clamping arms 101. A pin 102 is rotatably connected to the middle of the clamping arm 101. Both ends of the pin 102 are movably connected to the opposite surfaces of the housing 5 and the cover plate 6. Installation grooves 103 are respectively formed on the opposite surfaces of the two clamping arms 101. A first spring 104 is installed between the two installation grooves 103. One end of the two clamping arms 101 close to each other lapped with the end of the adjustment assembly 12, and one end of the two clamping arms 101 away from each other is connected to the clamping assembly 11.

[0040] The clamping arm 101 can rotate around the pin 102 in the middle, so that the end parts of the two clamping arms 101 drive the two clamping assemblies 11 to approach or move away from each other respectively, so as to facilitate the clamping or loosening of the blood vessel by the clamping assembly 11. And with the cooperation of the pin 102, the stability of the rotation of the clamping arm 101 is improved. During the rotation of the two clamping arms 101, the elastic force of the first spring 104 can support the two clamping arms 101, so that the end parts of the two clamping arms 101 can drive the two clamping assemblies 11 to open.

[0041] As a further solution of the present invention, the clamping assembly 11 includes a clamping plate 111. A hinge seat 112 is fixedly connected to the side of the clamping plate 111 close to the clamping arm 101. The end of the clamping arm 101 is hinged to the clamping plate 111 through the hinge seat 112. Anti-slip lines 113 are provided on the side of the clamping plate 111 away from the hinge seat 112. A pressure sensor 114 is installed in the middle of the clamping plate 111. The output end of the pressure sensor 114 is connected to a monitor 115 through a signal line. The monitor 115 is clamped in the empty groove formed at the end of the clamping arm 101. The monitor 115 is used to receive the pressure data fed back after the pressure sensor 114 is pressed.

[0042] During the process of the clamping plate 111 squeezing the blood vessel, the force between the two clamping plates 111 enables the clamping plate 111 to drive the hinge seat 112 to rotate at the end of the clamping arm 101, so that the two clamping plates 111 can adaptively adjust the angle and the two clamping plates 111 are in a parallel state. With the setting of the anti-slip lines 113 on one side of the clamping plate 111, the stability of the clamping of the blood vessel by the clamping plate 111 is improved. The pressure sensor 114 inside the clamping plate 111 can monitor the clamping force on the blood vessel. Since the output end of the pressure sensor 114 is connected to the monitor 115 through a signal line, the monitor 115 can receive the pressure data fed back after the pressure sensor 114 is pressed, so as to master the clamping force on the blood vessel.

[0043] As a further solution of the present invention, the adjustment assembly 12 includes a slide post 121, one end of which penetrates and slides in the housing 5 and is fixedly connected to a top block 124, and both sides of the top block 124 are designed to be inclined and overlap with the ends of the two clamping arms 101 that are close to each other. Because the two sides of the top block 124 are designed to be inclined, the top block 124 can push the ends of the two clamping arms 101 away from each other, so that the clamping arms 101 can rotate around the pin 102 in the middle, so that the other ends of the two clamping arms 101 respectively drive the two clamping assemblies 11 to approach each other, so that the clamping plates 111 in the clamping assemblies 11 facilitate stable clamping of the blood vessels.

[0044] One end of the sliding column 121 away from the top block 124 is fixedly connected with a piston seat 122, and the piston seat 122 is slidably connected in the air cylinder 4. The sliding column 121 is outer-mounted with a second spring 123, and the two ends of the second spring 123 are respectively fixedly connected to the piston seat 122 and one side of the inner wall of the air cylinder 4. When the clamping force is too large, by opening the exhaust valve 303 outside the air guide tube 301, the piston seat 122 is squeezed by the elastic force of the second spring 123, so that the piston seat 122 can move in the air cylinder 4 and drive the top block 124 to gradually move away from the ends of the two clamp arms 101, and the gas inside the air cylinder 4 passes through the air guide tube 301 and is discharged from the exhaust valve 303. At the same time, the other end of the clamp arm 101 drives the clamp plate 111 to gradually move away from the blood vessel through the hinge seat 112, thereby reducing the clamping force of the clamp plate 111 on the blood vessel, and avoiding the clamp plate 111 from excessively pressing the blood vessel to cause secondary damage to the blood vessel.

[0045] As a further solution of the present invention, a boosting assembly 13 is movably installed inside the boosting cylinder 1, and the boosting assembly 13 includes a sliding rod 131, the top end of the sliding rod 131 passes through the boosting cylinder 1 and is fixedly connected to a pressure plate 132; the end of the sliding rod 131 away from the pressure plate 132 is fixedly connected to a piston plate 133, and the piston plate 133 is slidably connected inside the boosting cylinder 1, and a third spring 134 is connected to the outer sleeve of the sliding rod 131, the top end of the third spring 134 is fixed to the top of the inner wall of the boosting cylinder 1, and the bottom end of the third spring 134 is fixed to the piston plate 133.

[0046] The two sides of the outer wall of the boost cylinder 1 are fixedly connected with baffles 14, and the bottom of the boost cylinder 1 is installed with a check valve 2 16. The boost cylinder 1 is connected to the revolving cylinder 2 through the check valve 2 16. A number of check valves 15 are equidistantly installed at the edge of the bottom of the boost cylinder 1. The check valve 15 is used to introduce gas into the boost cylinder 1, and can prevent the gas inside the boost cylinder 1 from being discharged through the check valve 1 15; the check valve 2 16 is used to introduce the gas inside the boost cylinder 1 into the revolving cylinder 2, and can prevent the gas inside the revolving cylinder 2 from flowing back into the boost cylinder 1 through the check valve 2 16.

[0047] When the piston plate 133 stops moving downward, release the pressure plate 132. Support the piston plate 133 by the elastic force of the third spring 134 so that the piston plate 133 can move upward inside the pressure increasing cylinder 1. The one-way valve 15 is used to introduce gas into the pressure increasing cylinder 1 and can prevent the gas inside the pressure increasing cylinder 1 from discharging through the one-way valve 15. When the pressure plate 132 is pushed downward again, the extracted gas can be re-introduced into the turnover cylinder 2 through the one-way valve 16 to facilitate continuous ventilation into the turnover cylinder 2.

[0048] A method for using a blood vessel clamp for surgical operations, the method comprising the following steps:

[0049] When using the blood vessel clamp, during the process of clamping a blood vessel at a specified position, move the deflection assembly 10 inside the housing 5 to the position of the blood vessel so that the two clamping assemblies 11 on the deflection assembly 10 are located on both sides of the clamped blood vessel. Place the fingers on the lower sides of the two baffles 14 outside the pressure increasing cylinder 1, and push the pressure plate 132 downward with the thumb, so that the pressure plate 132 drives the piston plate 133 to move downward through the sliding rod 131, and the gas inside the pressure increasing cylinder 1 enters the turnover cylinder 2 through the one-way valve 16. The one-way valve 16 is used to introduce the gas inside the pressure increasing cylinder 1 into the turnover cylinder 2 and can prevent the gas inside the turnover cylinder 2 from flowing back into the pressure increasing cylinder 1 through the one-way valve 16. When the piston plate 133 stops moving downward, release the pressure plate 132. Support the piston plate 133 by the elastic force of the third spring 134 so that the piston plate 133 can move upward inside the pressure increasing cylinder 1. The one-way valve 15 is used to introduce gas into the pressure increasing cylinder 1 and can prevent the gas inside the pressure increasing cylinder 1 from discharging through the one-way valve 15. When the pressure plate 132 is pushed downward again, the extracted gas can be re-introduced into the turnover cylinder 2 through the one-way valve 16 to facilitate continuous ventilation into the turnover cylinder 2.

[0050] At this time, the stop valve 302 is in the open state, and the exhaust valve 303 is in the closed state. The gas inside the turnover cylinder 2 then enters the air cylinder 4 through the stop valve 302 and the air duct 301. As the internal pressure of the air cylinder 4 increases, it pushes the piston seat 122 to move inside the air cylinder 4. The piston seat 122 drives the top block 124 to move inside the housing 5 through the sliding column 121, enabling the top block 124 to squeeze the ends of the two clamping arms 101 that are close to each other. Due to the inclined design on both sides of the top block 124, the top block 124 can push the ends of the two clamping arms 101 away from each other, allowing the clamping arms 101 to rotate around the pin 102 in the middle, and the other ends of the two clamping arms 101 drive the two clamping components 11 to approach each other respectively, making the clamping plates 111 in the clamping component 11 contact the blood vessel. As the clamping arms 101 continue to rotate, the two clamping plates 111 can clamp the blood vessel to block the blood flow on both sides inside the blood vessel. During the process of the clamping plates 111 squeezing the blood vessel, the force between the two clamping plates 111 enables the clamping plates 111 to drive the hinge seat 112 to rotate at the end of the clamping arm 101, allowing the two clamping plates 111 to adaptively adjust the angle and be in a parallel state. With the anti-slip pattern 113 provided on one side of the clamping plate 111, the stability of the clamping plate 111 on the blood vessel is improved.

[0051] During the process of the clamping plate 111 clamping the blood vessel, the pressure sensor 114 inside the clamping plate 111 can monitor the clamping force on the blood vessel. Since the output end of the pressure sensor 114 is connected to the monitor 115 through a signal line, the monitor 115 can receive the pressure data fed back after the pressure sensor 114 is pressed, so as to master the clamping force on the blood vessel. When the clamping force is too large, by opening the exhaust valve 303 outside the air duct 301, the piston seat 122 is squeezed by the elastic force of the second spring 123, enabling the piston seat 122 to move inside the air cylinder 4 and drive the top block 124 to gradually move away from the ends of the two clamping arms 101. At the same time, the elastic force of the first spring 104 can support the two clamping arms 101, making the clamping plates 111 at the ends of the clamping arms 101 move away from each other. The gas inside the air cylinder 4 passes through the air duct 301 and is discharged from the exhaust valve 303. At the same time, the other end of the clamping arm 101 drives the clamping plate 111 to gradually move away from the blood vessel through the hinge seat 112, thereby reducing the clamping force of the clamping plate 111 on the blood vessel and avoiding secondary damage to the blood vessel caused by excessive compression of the clamping plate 111 on the blood vessel. When the top block 124 no longer squeezes the two clamping arms 101, the clamping plates 111 at the ends of the two clamping arms 101 can move away from the blood vessel, thus facilitating the release of the clamping state of the blood vessel.

[0052] When clamping multiple blood vessels, open the stop valves 302 outside the multiple air ducts 301 so that the gas inside the turnover cylinder 2 can enter the multiple air ducts 301 simultaneously. The gas is then sent into the air cylinder 4 by the air ducts 301 to squeeze the piston seat 122. When the piston seat 122 drives the top block 124 to move through the sliding column 121, the ends of the two clamping arms 101 can drive the clamping assembly 11 to clamp the blood vessels, enabling the multiple deflection assemblies 10 to work synchronously, thereby achieving the purpose of synchronously clamping multiple blood vessels. Moreover, the check valve II 16 can prevent the gas from flowing back into the pressurizing cylinder 1, so that even if the pressurizing assembly 13 is not operated, the clamping assembly 11 can always maintain the corresponding clamping force, which is convenient for controlling the force applied to the blood vessels. When adjusting the clamping force of different blood vessels, one or several exhaust valves 303 outside the air ducts 301 can be opened so that the gas inside the air cylinder 4 can pass through the air ducts 301 and be discharged from the exhaust valves 303, enabling the position of the top block 124 to be adjusted, thereby facilitating the adjustment of the clamping force on the blood vessels; when one or several stop valves 302 are closed, the gas will no longer enter the air ducts 301, and the exhaust valves 303 and stop valves 302 outside the multiple air ducts 301 are independently designed, which can facilitate the independent adjustment of the clamping or loosening of different blood vessels.

8. A method for using a vascular clamp for surgical operations, the vascular clamp for surgical operations according to any one of claims 1-7, characterized in that, The method includes the following steps: When using this vascular clamp, during the process of clamping the blood vessel at a specified position, move the deflection assembly (10) inside the housing (5) to the position of the blood vessel, so that the two clamping assemblies (11) on the deflection assembly (10) are located on both sides of the blood vessel to be clamped. Place the fingers under the two baffles (14) outside the pressure increasing cylinder (1), and push the pressure plate (132) downward with the thumb, so that the pressure plate (132) drives the piston plate (133) to move downward through the sliding rod (131), and the gas inside the pressure increasing cylinder (1) enters the turnover cylinder (2) through the check valve II (16). The check valve II (16) is used to introduce the gas inside the pressure increasing cylinder (1) into the turnover cylinder (2), and can prevent the gas inside the turnover cylinder (2) from flowing back to the pressure increasing cylinder (1) through the check valve II (16). When the piston plate (133) stops moving downward, release the pressure plate (132), and support the piston plate (133) by the elastic force of the third spring (134), so that the piston plate (133) can move upward inside the pressure increasing cylinder (1). The check valve I (15) is used to introduce gas into the pressure increasing cylinder (1), and can prevent the gas inside the pressure increasing cylinder (1) from being discharged through the check valve I (15). When the pressure plate (132) is pushed downward again, the extracted gas can be re-introduced into the turnover cylinder (2) through the check valve II (16) to facilitate continuous ventilation into the turnover cylinder (2); At this time, the stop valve (302) is in the open state, and the exhaust valve (303) is in the closed state. The gas inside the turnover cylinder (2) then enters the air cylinder (4) through the stop valve (302) and the air duct (301). The pressure inside the air cylinder (4) increases, which drives the piston seat (122) to move inside the air cylinder (4). The piston seat (122) drives the top block (124) to move inside the housing (5) through the sliding column (121), so that the top block (124) can squeeze the ends of the two clamping arms (101) close to each other. The two sides of the top block (124) are designed in an inclined manner, and the top block (124) can push the ends of the two clamping arms (101) away from each other, so that the clamping arms (101) can rotate around the pin (102) in the middle, and the other ends of the two clamping arms (101) drive the two clamping assemblies (11) to approach each other respectively, so that the clamping plate (111) in the clamping assembly (11) contacts the blood vessel. As the clamping arms (101) continue to rotate, the two clamping plates (111) can clamp the blood vessel to block the blood flow on both sides inside the blood vessel. During the process of the clamping plate (111) squeezing the blood vessel, the force between the two clamping plates (111) enables the clamping plate (111) to drive the hinge seat (112) to rotate at the end of the clamping arm (101), so that the two clamping plates (111) can adaptively adjust the angle and be in a parallel state. With the anti-slip pattern (113) provided on one side of the clamping plate (111), the stability of the clamping plate (111) clamping the blood vessel is improved; During the process of the splint (111) clamping the blood vessel, the pressure sensor (114) inside the splint (111) can monitor the clamping force on the blood vessel. The output end of the pressure sensor (114) is connected to the monitor (115) through a signal line. The monitor (115) can receive the pressure data fed back after the pressure sensor (114) is pressed, so as to master the clamping force on the blood vessel. When the clamping force is too large, by opening the exhaust valve (303) outside the air duct (301), the piston seat (122) is squeezed by the elastic force of the second spring (123), so that the piston seat (122) can move in the air cylinder (4) and drive the top block (124) to gradually move away from the ends of the two clamping arms (101). At the same time, the elastic force of the first spring (104) can support the two clamping arms (101), so that the splints (111) at the ends of the clamping arms (101) can move away from each other. The gas inside the air cylinder (4) passes through the air duct (301) and is discharged from the exhaust valve (303). At the same time, the other end of the clamping arm (101) drives the splint (111) to gradually move away from the blood vessel through the hinge seat (112), thereby reducing the clamping force of the splint (111) on the blood vessel and avoiding secondary damage to the blood vessel caused by excessive compression of the splint (111) on the blood vessel. When the top block (124) no longer presses the two clamping arms (101), the splints (111) at the ends of the two clamping arms (101) can move away from the blood vessel, thereby facilitating the release of the clamping state of the blood vessel; When clamping multiple blood vessels, open the stop valves (302) outside the multiple air ducts (301), so that the gas inside the turnover cylinder (2) can enter the multiple air ducts (301) simultaneously. The gas is sent into the air cylinder (4) by the air duct (301) to squeeze the piston seat (122). When the piston seat (122) pushes the top block (124) to move through the sliding column (121), the ends of the two clamping arms (101) can drive the clamping assembly (11) to clamp the blood vessel, so that the multiple deflection assemblies (10) can work synchronously, thereby achieving the purpose of synchronously clamping multiple blood vessels. Moreover, the check valve II (16) can prevent the gas from flowing back into the booster cylinder (1). Even if the booster assembly (13) is not operated, the clamping assembly (11) can always maintain the corresponding clamping force, thereby facilitating the control of the force applied to the blood vessel. When adjusting the clamping force of different blood vessels, one or several exhaust valves (303) outside the air duct (301) can be opened, so that the gas inside the air cylinder (4) can pass through the air duct (301) and be discharged from the exhaust valve (303), and the position of the top block (124) can be adjusted, so as to facilitate the adjustment of the clamping force of the blood vessel. When closing one or several stop valves (302), the gas will no longer enter the air duct (301), and the exhaust valves (303) and stop valves (302) outside the multiple air ducts (301) are independently designed, which can facilitate the independent adjustment of the clamping or loosening of different blood vessels.
