Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a fixed compression structure for radial artery interventional puncture surgery. Background Art

[0002] Since interventional surgery generally involves arterial puncture, it is very important to press and stop bleeding of the radial artery after the surgery, and it needs to be continuously carried out for a long time to achieve the effect of hemostasis. However, the current method cannot achieve better compression hemostasis, resulting in poor hemostasis effect and bringing great trouble to the post-interventional period.

[0003] In view of the above technical problems, Chinese Patent No. CN213047119U discloses a compression device for puncture interventional surgery. By arranging a swing plate and an insertion plate on the right side of the top arc plate, the position of the compression pad can be adjusted by changing the insertion depth of the insertion plate, so that the compression pad can initially compress and stop bleeding at the puncture site, and further precise clamping adjustment can be achieved by changing the circumferential and radial positions of the compression pad, so as to achieve continuous and stable compression hemostasis while making the patient in the most comfortable state.

[0004] However, after the radial artery interventional puncture surgery is actually performed, it is necessary to compress a specific position, that is, the puncture site. However, the above-mentioned compression device for puncture interventional surgery has a low accuracy for fixed-point compression, and moreover, it cannot adjust the compression intensity, resulting in the phenomenon that the compression intensity is either insufficient or too large, both of which will cause secondary damage to the puncture site.

[0040] As Figures 1 to 8 shown, an embodiment of the present invention provides a fixed compression structure for radial artery interventional puncture surgery. In order to achieve a wearable fixation effect on a patient, a wearable positioning mechanism 1 needs to be provided, which internally has an arc-shaped positioning plate 11 that can be bound to the patient's wrist, a component fixing cavity 15 provided inside the arc-shaped positioning plate 11 and having an open top, a first rod body perforation 16 provided at the bottom of the arc-shaped positioning plate 11, and an annular permanent magnet 19 fixedly installed at the top of the arc-shaped positioning plate 11. The arc-shaped positioning plate 11 is abutted against the outside of the wrist limb, and then the right adhesive tape 12 and the left adhesive tape 13 are made to bypass the other side of the limb, so as to be adhered to form a complete working state. At this time, it is necessary to make the first rod body perforation 16 face the puncture point of the patient, so as to achieve the wearable fixation effect on the patient.

[0041] As Figure 3 and Figure 4As shown, the wearable positioning mechanism 1 includes an arc-shaped positioning plate 11. Concave structure belt body embedding grooves 14 are respectively arranged at the arc-shaped end parts of the arc-shaped positioning plate 11. A right-side adhesive tape 12 and a left-side adhesive tape 13 are respectively installed inside the arc-shaped positioning plate 11 at positions corresponding to the two belt body embedding grooves 14. A columnar protrusion structure 110 integrated with the arc-shaped positioning plate 11 is arranged at the center of the arc-shaped positioning plate 11. A component fixing cavity 15 with an open top is arranged inside the columnar protrusion structure 110. A first rod body through hole 16 communicating the bottom end of the component fixing cavity 15 and the space below is arranged at the center of the bottom end of the columnar protrusion structure 110. A bearing installation groove 17 is arranged at the periphery of the middle area of the component fixing cavity 15 in the columnar protrusion structure 110. A bearing is installed inside the bearing installation groove 17 in the columnar protrusion structure 110. A concave structure permanent magnet embedding groove 18 is arranged at the periphery of the top opening of the component fixing cavity 15 at the top end of the columnar protrusion structure 110. A ring-shaped permanent magnet 19 is fixedly installed inside the permanent magnet embedding groove 18 in the columnar protrusion structure 110. The outer ring surface of the bearing located inside the bearing installation groove 17 is fixedly installed at the circumferential inner wall of the bearing installation groove 17, and the structural radius of the inner ring surface of this bearing is smaller than the structural radius of the component fixing cavity 15. The horizontal height of the top end of the ring-shaped permanent magnet 19 is higher than the horizontal height of the top end of the permanent magnet embedding groove 18.

[0042] As Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in order to achieve the function of adjusting the compression intensity of the puncture point of the patient, a threaded adjustment type compression mechanism 2 needs to be set. Inside it, there is a first hollow column 21 installed in the component fixing cavity 15 through a bearing and capable of rotating, a limit collar 24 sleeved on the outer circumferential surface of the first hollow column 21 and capable of adsorbing on the top of the annular permanent magnet 19, a threaded moving plate 29 installed inside the first hollow column 21 through a threaded structure 210, and when the first hollow column 21 rotates, it can produce a longitudinal movement phenomenon, and an arc-shaped compression plate 212 located directly below the wearable positioning mechanism 1 and capable of longitudinally moving with the threaded moving plate 29. Pull the limit collar 24 upward so that the limit collar 24 is out of the adsorption range of the annular permanent magnet 19. The first connecting plate 27 will rotate with the second connecting plate 39, thereby driving the first hollow column 21 to rotate. When the first hollow column 21 rotates, due to the connection of the threaded structure 210 and the influence of the longitudinal push rod 211 being limited by the first rod body perforation 16, the threaded moving plate 29 will move longitudinally, causing the threaded moving plate 29 to move downward until the arc-shaped compression plate 212 touches the puncture point of the patient with a certain pressure. Then, adsorb the limit collar 24 on the upper surface of the annular permanent magnet 19, so that the limit collar 24 produces a limiting and fixing effect on the first hollow column 21, preventing the first hollow column 21 from rotating, to ensure the stability of the work, and thus achieve the function of adjusting the compression intensity of the puncture point of the patient.

[0043] As Figure 5 and Figure 6As shown, the screw-adjustable pressing mechanism 2 includes a first hollow column 21 and a limiting collar 24. The side surface of the first hollow column 21 is provided with a limiting side surface 22 in the upper half and a cylindrical side surface 23 in the lower half. The outer peripheral structure of the first hollow column 21 located at the cylindrical side surface 23 is fixedly installed on the inner ring surface of the bearing inside the bearing installation groove 17. The top of the first hollow column 21 is provided with a first connecting plate 27 integrally structured with it. The inside of the first hollow column 21 is provided with an internal thread cavity 26. The center of the bottom end of the first hollow column 21 is provided with a second rod body through hole 28 communicating the bottom end of the internal thread cavity 26 and the space below. Inside the first hollow column 21 located in the internal thread cavity 26, a threaded moving plate 29 is installed through a thread structure 210. The bottom end of the threaded moving plate 29 is fixedly installed with a longitudinal push rod 211 passing through the second rod body through hole 28 and the first rod body through hole 16. The bottom end of the longitudinal push rod 211 is fixedly installed with an arc-shaped pressing plate 212. The center of the limiting collar 24 is provided with a limiting sleeve hole 25 that can be sleeved around the outer periphery of the limiting side surface 22 and is made of iron material. The thread structure 210 includes an internal thread structure provided on the circumferential inner wall of the internal thread cavity 26 and an external thread structure provided on the outer circumferential surface of the threaded moving plate 29, and the internal thread structure matches the external thread structure. The structural shape of the cross-section of the limiting sleeve hole 25 is the same as the structural shape of the cross-section of the limiting side surface 22, both being polygonal structures. The structural shape of the cross-section of the first rod body through hole 16 is the same as the structural shape of the cross-section of the longitudinal push rod 211, both being polygonal structures, and the structural dimension of the cross-section of the longitudinal push rod 211 is smaller than the structural radius of the second rod body through hole 28.

[0044] As Figure 1 , Figure 2 , Figure 7 and Figure 8As shown in the figure, in order to control the rated value of the compression intensity and prevent the occurrence of insufficient pressure or excessive overload pressure, it is necessary to set up a pressure-controllable driving mechanism 3. Inside it, there is a second hollow column 31 that can rotate and is hollow inside, a piston plate 314 placed inside the second hollow column 31 and that moves downward under gas pressure, a middle connecting rod 313 installed at the bottom of the piston plate 314 and that can rotate with the second hollow column 31, an arc-shaped brake block 312 fixedly installed at the bottom end of the middle connecting rod 313 and that can move with the middle connecting rod 313, and a lower rotating disk 310 installed inside the second hollow column 31 in a rotatable manner and that can rotate with the arc-shaped brake block 312 and drive the first connecting plate 27 to rotate. According to the user group, an inflation device is used to inject gas with an appropriate pressure into the gas compensation channel 37, the gas limiting storage cavity 36, and the upper component movable cavity 35. Under the action of the gas pressure, the piston plate 314 will generate a downward pressure on the upper rotating disk 315, and finally the arc-shaped brake block 312 will contact the upper surface of the lower rotating disk 310 with a rated pressure. Rotating the second hollow column 31 will drive the middle connecting rod 313 to rotate, and then drive the upper rotating disk 315 to rotate. Due to the static friction between the arc-shaped brake block 312 and the lower rotating disk 310, the lower rotating disk 310 will drive the second connecting plate 39 to rotate, realizing the transmission function of the rotation effect. When the torque resistance formed by the compression resistance is greater than the above-mentioned static friction, a relative movement phenomenon will occur between the arc-shaped brake block 312 and the lower rotating disk 310, thereby preventing the further increase of the compression intensity, and further preventing the occurrence of insufficient pressure or excessive overload pressure.

[0045] As Figure 7 and Figure 8As shown in the figure, the pressure controllable driving mechanism 3 includes a second hollow column 31. An inner part of the second hollow column 31 is provided with a lower component moving cavity 32. At the bottom end of the second hollow column 31 where it is located at the lower component moving cavity 32, a shaft body mounting hole 33 communicating with the external space is provided. At the top end of the second hollow column 31 where it is located at the lower component moving cavity 32, a third rod body perforation 34 is provided. At the top end of the second hollow column 31 where it is located at the third rod body perforation 34, an upper component moving cavity 35 is provided. At the top end of the second hollow column 31 where it is located at the upper component moving cavity 35, a gas limiting storage cavity 36 is provided. At the top end of the second hollow column 31 where it is located at the gas limiting storage cavity 36, a gas compensation channel 37 communicating with the top of the gas limiting storage cavity 36 and having a gas valve placed inside is provided. Inside the shaft body mounting hole 33 of the second hollow column 31, a rotatable rotating shaft 38 is installed through a bearing. At the bottom end of the rotating shaft 38, a second connecting plate 39 which is integrally structured with it and fixedly connected to the first connecting plate 27 is provided. At the top end of the rotating shaft 38, a lower rotating disk 310 located inside the lower component moving cavity 32 is fixedly installed. Inside the upper component moving cavity 35 of the second hollow column 31, a piston plate 314 capable of axially moving along the upper component moving cavity 35 is placed. At the bottom end of the piston plate 314, a middle connecting rod 313 penetrating through the middle of the third rod body perforation 34 is fixedly installed. At one end of the middle connecting rod 313 located inside the lower component moving cavity 32, an upper rotating disk 315 is fixedly installed. At the bottom end of the upper rotating disk 315, three arc-shaped mounting grooves 311 arranged in a circumferential array are provided. Inside the arc-shaped mounting grooves 311 of the upper rotating disk 315, arc-shaped braking blocks 312 are fixedly installed. The structural shape of the cross-section of the third rod body perforation 34 is the same as that of the cross-section of the middle connecting rod 313, both being a polygonal structure.

[0046] The working process of the technical solution provided by the present invention is as follows:

[0047] Press the arc-shaped positioning plate 11 against the outside of the wrist limb, and then make the right adhesive tape 12 and the left adhesive tape 13 bypass the other side of the limb, so as to paste and form a complete working state. At this time, it is necessary to make the first rod body perforation 16 face the puncture point of the patient.

[0048] According to the user group, an inflation device is used to inject gas with an appropriate pressure into the internal parts of the gas compensation channel 37, the gas limiting storage cavity 36, and the upper component moving cavity 35. Under the action of the gas pressure, a downward pressure will be generated on the upper rotating disk 315 by the piston plate 314. Finally, the arc-shaped brake block 312 will contact the upper surface of the lower rotating disk 310 with a rated pressure. Rotating the second hollow column 31 will drive the middle connecting rod 313 to rotate, and then drive the upper rotating disk 315 to rotate. Due to the static friction between the arc-shaped brake block 312 and the lower rotating disk 310, the lower rotating disk 310 will drive the second connecting plate 39 to rotate.

[0049] Pull the limit collar 24 upward so that the limit collar 24 is out of the adsorption range of the annular permanent magnet 19. The first connecting plate 27 will rotate with the second connecting plate 39, thereby driving the first hollow column 21 to rotate. When the first hollow column 21 rotates, due to the connection of the thread structure 210 and the influence of the longitudinal push rod 211 being limited by the first rod body perforation 16, the threaded moving plate 29 will move longitudinally, causing the threaded moving plate 29 to move downward until the arc-shaped pressing plate 212 contacts the puncture point of the patient with a certain pressure, and then the limit collar 24 is adsorbed on the upper surface of the annular permanent magnet 19.

[0050] When the torque resistance formed by the compression resistance is greater than the above-mentioned static friction, a relative movement phenomenon will occur between the arc-shaped brake block 312 and the lower rotating disk 310. Once a relative movement phenomenon occurs between the two, the medical staff can immediately stop the rotating work and complete the wearing and pressing work.

[0051] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0052] The above are only the preferred embodiments of the present invention.
