Description

Technical Field

[0001] The present invention relates to the technical field of vascular sheath clamping, and more particularly to a vascular sheath clamping device. Background Art

[0002] A vascular sheath, also known as a catheter insertion sheath or catheter sheath, is a crucial medical device in vascular interventional diagnosis and treatment. The vascular sheath clamping device is primarily used in vascular interventional procedures to provide doctors with a stable and reliable vascular access. During surgery, doctors need to access the blood vessels through a skin puncture and then use the vascular sheath as a channel to introduce interventional devices such as catheters, balloons, and stents for diagnosis and treatment. The vascular sheath clamping device is used to secure the vascular sheath during the puncture process and after the procedure, ensuring its stable position and preventing displacement or dislodgement, thereby ensuring the smooth progress of the procedure and the safety of the patient.

[0003] Because vascular sheaths come in different sizes and specifications, the appropriate size of sheath needs to be selected based on the thickness of the blood vessel. Existing clamping devices are not convenient for clamping vascular sheaths of different sizes. Moreover, when clamping and puncturing the vascular sheath, the puncture force of vascular sheaths of different sizes also varies. For deeper blood vessels or surgical sites that need to avoid damaging surrounding tissue, doctors may choose a smaller puncture angle; for shallower blood vessels or surgical sites that require rapid access to the blood vessel, doctors may choose a larger puncture angle. Existing vascular sheaths are not convenient for synchronously adjusting the puncture force according to the puncture angle of the vascular sheath. In response to the above problems, innovative designs based on the existing ones are urgently needed. Summary of the Invention

[0043] like Figures 1 to 10As shown, an embodiment of the present invention provides a vascular sheath clamping device, including a pressing plate 1, a turntable 2 is rotatably connected to the bottom of the side end of the pressing plate 1, and a rotating shaft is rotatably connected inside the turntable 2. An adjusting rod 3 is slidably connected to the inside of the turntable 2 through the rotating shaft. The adjusting rod 3 is arc-shaped, and a boss is fixedly connected to the bottom of the adjusting rod 3. The length and width of the boss are both larger than the bottom of the adjusting rod 3. A bolt is threadedly connected to the side end of the turntable 2, and a connecting rod 4 is rotatably connected to the top side of the adjusting rod 3. A striking platform 5 is provided at one end of the connecting rod 4, and a closing platform 6 is provided inside the striking platform 5. A bidirectional screw rod 7 is rotatably connected to the closing platform 6. Two groups of clamping blocks 8 are sliding on both sides of the closing platform 6. The two groups of clamping blocks 8 are threadedly connected to the bidirectional screw rod 7. A first sliding rod 10 is fixedly installed inside the striking platform 5. The number of the first sliding rods 10 is two groups, and they are symmetrically distributed in the area near the two sides of the striking platform 5. The closing platform 6 is slidably connected to the first sliding rod 10.

[0044] The clamping adaptation adjustment component 9 is arranged inside the upper and lower ends of the clamping block 8 and the top side of the adjustment rod 3. The clamping adaptation adjustment component 9 is used to deflect the vascular sheath to an appropriate puncture angle according to the specifications and size of the vascular sheath.

[0045] The force adjustment component 11 is disposed inside the striking platform 5 . The force adjustment component 11 is used to provide different puncture forces to vascular sheaths of different specifications according to the specifications and sizes of the vascular sheaths.

[0046] The position compensation component 12 is arranged at the end of the connecting rod 4 and the back end of the striking platform 5. The position compensation component 12 can keep the vascular sheath at the same initial height when the puncture force of vascular sheaths of different specifications changes.

[0047] like Figures 1 to 4 As shown, the two groups of clamps 8 are symmetrically distributed inside the closing table 6, the adjusting rod 3 is arc-shaped and has a protrusion connected to the bottom. The arc-shaped design of the adjusting rod 3 allows one end to be close to the patient when extended, and the length and width of the protrusion are both larger than the bottom of the adjusting rod 3. The design of the bottom protrusion here can prevent the adjusting rod 3 from sliding out of the pressure plate 1, and the bolts at the side end of the turntable 2 can also fix and limit the adjusting rod 3.

[0048] like Figure 4 As shown, the clamping block 8 is composed of a long arm and a long block. An arc-shaped notch is provided on the inner side of the long block. The arc-shaped notch is designed to fit the surface of the vascular sheath.

[0049] When in use, the existing clamping device is not convenient for clamping vascular sheaths of different specifications, and when clamping and puncturing the vascular sheath, the puncture force of vascular sheaths of different sizes is also different. The existing vascular sheath is not convenient for synchronously adjusting the puncture force according to the puncture angle of the vascular sheath. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the pressing plate 1 is placed under the mattress of the DSA bed, and the patient's buttocks position is pressed according to different intervention positions. Then the vascular sheath is placed in the arc-shaped notch of the clamp block 8, and then the motor is used to make the double The screw rod 7 is rotated to close the two sets of clamping blocks 8. When the clamping blocks 8 are closed, the clamping pad 904 will be squeezed by the vascular sheath, and the first elastic telescopic rod 905 will make the clamping pad 904 fit tightly with the surface of the vascular sheath to clamp it. When the pressure block 909 is squeezed by the vascular sheath, it will squeeze the first piston rod 907, so that the oil inside the first oil tank 906 is injected into the second oil tank 911, so that the second piston rod 912 pushes the rack 913 to drive the gear 910 to rotate, thereby driving the connecting rod 4 to rotate synchronously, thereby adjusting the puncture angle of the vascular sheath.

[0050] When the rack 913 moves, it will squeeze the third piston rod 112, so that the oil in the third oil tank 111 is injected into the fourth oil tank 113 and the fifth oil tank 124. The fourth oil tank 113 will push the fourth piston rod 114 to drive the electric push rod 115 to rise, thereby changing the initial height of the vascular sheath, causing the puncture depth of the vascular sheath to change, thereby changing its puncture force. When the oil is injected into the fifth oil tank 124, the oil will push the fifth piston rod 125 to slide outward. At this time, the squeezing block 126 will squeeze the first slider 122 and the second slider 123, so that the striking platform 5 moves downward, thereby compensating for the rising height of the vascular sheath, so that vascular sheaths of different specifications can maintain the same height before puncture, ensuring that the puncture force can change synchronously with the specifications of the vascular sheath, and then the vascular sheath is punctured by the electric push rod 115.

[0051] like Figures 3 to 8As shown, the clamping adaptation adjustment component 9 includes a first connecting platform 901 fixedly connected to the top of the clamping block 8 and a second connecting platform 902 fixed to the side end of the clamping block 8, two groups of support rods 903 are fixedly connected to the side of the first connecting platform 901 near the end positions on both sides, and the ends of the support rods 903 are fixedly connected to the clamping pads 904, and the central part of the side of the first connecting platform 901 is fixedly connected to the first elastic telescopic rod 905, and the extended end of the first elastic telescopic rod 905 is fixedly connected to the clamping pad 904, and the interior of the second connecting platform 902 is fixedly connected to the first oil tank 906, and the interior of the first oil tank 906 is slidably connected to the first piston rod 907, and one end of the second connecting platform 902 is fixedly connected to the second elastic telescopic rod 908, and the extended end of the second elastic telescopic rod 908 is fixedly connected to the pressing block 909. The back end of the pressure block 909 conflicts with the first piston rod 907, and the end of the connecting rod 4 is fixedly connected to a gear 910, which is rotatably connected to the top side of the adjusting rod 3. One end of the side of the adjusting rod 3 is fixedly connected to a second oil tank 911, and a second piston rod 912 is slidably connected inside the second oil tank 911. The end of the second piston rod 912 is fixedly connected to a rack 913, and the rack 913 is meshed with the gear 910. A hose is connected between the first oil tank 906 and the second oil tank 911, so that the clamping device can adapt to vascular sheaths of various specifications, and there is no need to prepare multiple clamping devices for vascular sheaths of different sizes, thereby improving the flexibility and efficiency of the operation, and the puncture angle of the vascular sheath is synchronously adjusted according to the size specifications of the vascular sheath, so that it can be adjusted to a puncture angle suitable for itself.

[0052] like Figure 3 and Figure 4 As shown, the clamping pad 904 is made of natural rubber, the middle part of the pressing block 909 is an arc-shaped surface, and the surfaces on both sides of the pressing block 909 are flat. The natural rubber material has good physical and mechanical properties, and its traceability and anti-slip effects are good, and it can clamp the vascular sheath well. The arc surface design of the pressing block 909 can be evenly squeezed when it contacts the vascular sheath.

[0053] The vascular sheath is placed in the arc-shaped notch of the clamp block 8, and then the bidirectional screw rod 7 is rotated by the motor to close the two sets of clamp blocks 8. When the clamp blocks 8 are closed, the clamping pad 904 will be squeezed by the vascular sheath, and the first elastic telescopic rod 905 will make the clamping pad 904 fit tightly with the surface of the vascular sheath to clamp it. The clamping adaptation adjustment component 9 enables the clamping device to adapt to vascular sheaths of various specifications, and there is no need to prepare multiple clamping devices for vascular sheaths of different sizes, thereby improving the flexibility and efficiency of the operation, and the puncture angle of the vascular sheath is synchronously adjusted according to the size specifications of the vascular sheath, so that it can be adjusted to a puncture angle suitable for itself. Precise clamping and angle adjustment help doctors to position and operate more accurately during surgery, and ensure the stability and accuracy of the vascular sheath during the puncture process.

[0054] like Figures 5 to 8 As shown, the force adjustment component 11 includes a third oil tank 111 fixedly connected to one end of the side of the adjustment rod 3, a third piston rod 112 is slidably connected inside the third oil tank 111, and the end of the third piston rod 112 is fixedly connected to the rack 913, a fourth oil tank 113 is fixedly connected to the internal notch of the striking table 5, a fourth piston rod 114 is slidably connected inside the fourth oil tank 113, and a protrusion is fixedly connected to the end of the fourth piston rod 114, which is fixedly connected to the side end of the electric push rod 115, and the protruding end of the electric push rod 115 is fixedly connected to the closing table 6. A hose is connected between the liquid tanks 113, and the puncture force of the vascular sheath can be adjusted synchronously according to the puncture angle of the vascular sheath. After the clamping adapter adjustment component 9 clamps the vascular sheath, the first piston rod 907 is squeezed to inject the oil inside the first oil tank 906 into the second oil tank 911, so that the second piston rod 912 pushes the rack 913 to move. When the rack 913 moves, it will rotate the gear 910 to deflect the connecting rod 4, so that the deflection angle can be adjusted according to the size of the vascular sheath. When the rack 913 moves, it will squeeze the third piston rod 112 to make the third piston rod 112 The internal oil of the three oil tanks 111 is respectively injected into the fifth oil tank 124 and the fourth oil tank 113. In the initial state, the puncture of the vascular sheath is achieved by the electric push rod 115. When the rack 913 squeezes the third piston rod 112, the internal oil of the third oil tank 111 will move the position of the electric push rod 115 in the opposite direction of the puncture position after being injected into the fourth oil tank 113. By changing the initial height of the electric push rod 115, the puncture depth of vascular sheaths of different specifications under the same puncture surface can be made different. After the internal oil of the third oil tank 111 is injected into the fifth oil tank 124, it can be ensured that The height of the striking platform 5 of vascular sheaths of the same specification can be at the same horizontal plane. By changing the height of the internal electric push rod 115 inside the striking platform 5 at the same horizontal plane, the synchronous change of the vascular sheath puncture force can be achieved. Regarding the adaptive change of force and angle, the specific values are determined according to actual usage. The present invention does not limit the specific size of each component. The force adjustment component 11 can accurately control the puncture force of the vascular sheath, avoiding puncture failure caused by excessive or insufficient force. According to the synchronous adjustment of the puncture angle, it can be ensured that the vascular sheath enters the blood vessel at the optimal angle with appropriate force.

[0055] like Figures 5 to 7 As shown, a spring is fixedly connected to the bottom of the inner wall of the striking platform 5, and the upper end of the spring is fixedly connected to the bottom of the closing platform 6. The spring is sleeved on the surface of the first slide rod 10. When the clamping device loosens the vascular sheath, the spring will automatically reset the closing platform 6.

[0056] When the rack 913 moves, it will squeeze the third piston rod 112, so that the oil in the third oil tank 111 will be injected into the fourth oil tank 113 and the fifth oil tank 124. The fourth oil tank 113 will push the fourth piston rod 114 to drive the electric push rod 115 to rise, thereby changing the initial height of the vascular sheath, causing the puncture depth of the vascular sheath to change, thereby changing its puncture force. The force adjustment component 11 can accurately control the puncture force of the vascular sheath, avoiding puncture failure caused by excessive or insufficient force. According to the synchronous adjustment of the puncture angle, it can ensure that the vascular sheath enters the blood vessel at the optimal angle with appropriate force.

[0057] like Figures 9 to 11 As shown, the position compensation component 12 includes a second slide bar 121 installed at the back end of the striking platform 5, the middle part of the second slide bar 121 is fixedly connected to the first slide bar 122, the side end of the connecting rod 4 is fixedly installed with the second slide bar 123, the second slide bar 123 is at the upper end of the first slide bar 122, the second slide bar 123 slides on the surface of the second slide bar 121, and the other end of the connecting rod 4 is fixedly installed with a fifth oil tank 124, the inside of the fifth oil tank 124 is slidably connected with a fifth piston rod 125, the end of the fifth piston rod 125 is fixedly connected with an extrusion block 126, and a hose is connected between the third oil tank 111 and the fifth oil tank 124. When the puncture force of vascular sheaths of different specifications changes, the vascular sheaths can maintain the same initial height, so that the initial positions of vascular sheath puncture needles of different specifications are unified.

[0058] like Figure 9 and Figure 10 As shown, the second slide bar 121, the first slide block 122 and the second slide block 123 are each in two groups, and are symmetrically distributed near the two ends on the back of the striking platform 5. The design of the two groups of the second slide bar 121, the first slide block 122 and the second slide block 123 can ensure that the striking platform 5 can descend smoothly.

[0059] like Figure 11 As shown, the fifth oil tank 124 is a bidirectional oil tank, the number of the fifth piston rod 125 is two groups, and the surface of the extrusion block 126 is provided with a smooth inclined surface. The design of the smooth surface of the extrusion block 126 can better squeeze the first slider 122 and the second slider 123, thereby compensating for the puncture depth and allowing vascular sheaths of different specifications to be at the same initial height.

[0060] When the oil is injected into the fifth oil tank 124, the oil will push the fifth piston rod 125 to slide outward. At this time, the squeezing block 126 will squeeze the first slider 122 and the second slider 123, so that the striking platform 5 moves downward, thereby compensating for the rising height of the vascular sheath, so that vascular sheaths of different specifications can maintain the same height before puncture. When the puncture force of vascular sheaths of different specifications changes, the position compensation component 12 can keep the vascular sheaths of different specifications at the same initial height, so that the initial positions of vascular sheath puncture needles of different specifications are unified, and doctors do not need to frequently adjust the initial position of the puncture needle according to vascular sheaths of different specifications.

[0061] The workflow of the technical solution provided by the present invention is as follows:

[0062] During use, the pressing plate 1 is placed under the mattress of the DSA bed, and is pressed tightly with the patient's buttocks according to different intervention positions. The vascular sheath is then placed in the arc-shaped notch of the clamp block 8. The bidirectional screw rod 7 is then rotated by the motor to close the two sets of clamp blocks 8. When the clamp blocks 8 are closed, the clamping pad 904 will be squeezed by the vascular sheath, and the first elastic telescopic rod 905 will make the clamping pad 904 fit tightly with the surface of the vascular sheath to clamp it. When the pressure block 909 is squeezed by the vascular sheath, it will squeeze the first piston rod 907, so that the oil inside the first oil tank 906 is injected into the second oil tank 911, so that the second piston rod 912 pushes the rack 913 to drive the gear 910 to rotate, thereby driving the connecting rod 4 to rotate synchronously, thereby adjusting the vascular sheath puncture angle.

[0063] When the rack 913 moves, it will squeeze the third piston rod 112, so that the oil in the third oil tank 111 is injected into the fourth oil tank 113 and the fifth oil tank 124. The fourth oil tank 113 will push the fourth piston rod 114 to drive the electric push rod 115 to rise, thereby changing the initial height of the vascular sheath, causing the puncture depth of the vascular sheath to change, thereby changing its puncture force. When the oil is injected into the fifth oil tank 124, the oil will push the fifth piston rod 125 to slide outward. At this time, the squeezing block 126 will squeeze the first slider 122 and the second slider 123, so that the striking platform 5 moves downward, thereby compensating for the rising height of the vascular sheath, so that vascular sheaths of different specifications can maintain the same height before puncture, ensuring that the puncture force can change synchronously with the specifications of the vascular sheath, and then the vascular sheath is punctured by the electric push rod 115.
