Description

Technical Field

[0001] This invention belongs to the field of surgical nursing hemostasis technology, specifically referring to an interventional nursing device for vascular surgery. Background Technology

[0002] Postoperatively, vascular interventional procedures (such as aortic stent implantation via femoral artery puncture, lower extremity arteriovenous angioplasty, etc.) require prolonged pressure application to the puncture site for hemostasis. Current clinical methods and their limitations are as follows: Manual compression combined with sandbags / elastic bandages: uneven and unquantifiable pressure, prone to displacement, poor patient comfort, and high workload for nursing staff.

[0003] Airbag compressor: relies on airtightness, which poses a risk of air leakage; requires frequent pressure checks and has inaccurate pressure adjustment; electronic air pumps rely on power and are not suitable for transport scenarios.

[0004] Spiral mechanical compressors, while solving the problem of continuous constant pressure, rely entirely on the operator's experience and feel, lacking an objective feedback mechanism. Insufficient tightening can lead to bleeding and hematoma; excessive tightening can cause tissue necrosis or nerve damage. Furthermore, existing devices are cumbersome to operate when rapid pressure release is needed to observe the puncture site, often requiring complete disassembly.

[0005] Therefore, there is an urgent need for a purely mechanical interventional nursing device that can provide accurate pressure feedback and overpressure protection, and can be quickly released with one button to fully expose the puncture site, so as to reduce the dependence on personnel experience and improve safety and nursing efficiency. Summary of the Invention

[0006] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an interventional nursing device for vascular surgery. When in the horizontal position, the locking platform engages with the latch to achieve locking. Pressing the elastic locking tongue automatically unlocks the device, and the cantilever rod instantly springs open and flips upward under the action of the torsion spring, relieving all pressure and fully exposing the puncture area. During tightening, torque is transmitted to the drive nut via steel balls. When the pressure plate contacts the limb and generates a reaction force, the tightening resistance torque increases linearly with the pressure. When the resistance torque exceeds the set threshold, the steel balls compress the spring and slide out of the recess, causing the driving plate to slip relative to the driven plate in a jumping motion, producing a clear "click" sound and tactile vibration feedback. At this point, no matter how the knob is rotated, the pressure will no longer increase, achieving mechanical constant force protection and pressure upper limit indication.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes an interventional nursing device for vascular surgery, including a torque limiting component, a lifting and compression component, a cantilever support component, a quick unlocking component, and a bottom support component. The torque limiting component is rotatably mounted on the lifting and compression component, and the lifting and compression component is located at the end of the cantilever support component. The cantilever support component is located on one side of the bottom support component, and the quick unlocking component is located on the cantilever support component. Furthermore, the torque limiting component includes an active disk, a driven disk, and a steel ball. The active disk and the driven disk are capable of relative rotation and axial sliding. The steel ball is located between the active disk and the driven disk. When the steel ball is engaged in the groove of the active disk and the driven disk, the active disk and the driven disk are relatively stationary. When the steel ball rolls between the active disk and the driven disk, the active disk and the driven disk move relative to each other.

[0008] Preferably, the torque limiting assembly further includes a handle and a spring. The handle is provided with a guide groove, and the drive disc is provided with a guide portion that matches the guide groove. The drive disc is slidably disposed in the guide groove by engaging with the guide portion. The spring is located between the handle and the drive disc.

[0009] Furthermore, the lifting and pressing assembly includes a guide member and a screw. The guide member is provided with a guide rod, which is engaged and slidably disposed in the cantilever support assembly. The screw is provided with a pressing plate, and the guide member is fixedly connected to the pressing plate.

[0010] Preferably, the lifting and pressing assembly further includes a nut and a pressing liner. The nut is rotatably disposed in the cantilever support assembly, the driven plate is fixed to the nut, and there is threaded transmission between the screw and the nut. The pressing liner is disposed at the bottom of the pressing plate.

[0011] Furthermore, the cantilever support assembly includes a fixed bracket, a cantilever rod, and a hinge shaft. The fixed bracket is disposed on the bottom support assembly, the hinge shaft is fixedly connected to the fixed bracket, the cantilever rod is rotatably disposed on the hinge shaft, the guide rod is engaged and slidably disposed at the end of the cantilever rod, and the nut is rotatably disposed at the end of the cantilever rod.

[0012] Preferably, the cantilever support assembly further includes a torsion spring, the two ends of which are fixedly connected to the fixed bracket and the cantilever rod respectively. Under the elastic force of the torsion spring, the cantilever rod has an upward tendency.

[0013] Furthermore, the quick-unlocking component includes a latch and a resilient locking tongue. The latch is fixed to the lower part of the cantilever rod, and the resilient locking tongue is fixed to the side of the fixed bracket. The end of the resilient locking tongue is provided with a locking plate that cooperates with the latch.

[0014] Furthermore, the bottom support assembly includes a bottom bracket and a bottom liner, the bottom liner being disposed in the bottom bracket, and the fixing bracket being fixed to the side of the bottom bracket.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The torque limiting component can limit the upper limit of the torque applied to the nut, thereby automatically unloading the force by slipping when the torque is too large, thus avoiding the problem of excessive pressure on the target position.

[0016] (2) The steel ball is located in the groove of the active plate and the driven plate. The rotational motion of the active plate is transmitted to the driven plate through shearing force. When the reaction force of the shearing force on the active plate is greater than the elastic force of the spring, the active plate and the driven plate will move away from each other and slip through the rolling of the steel ball, thereby achieving the technical purpose of setting the upper limit of torque.

[0017] (3) By the longitudinal movement of the compression disc, pressure can be applied to the target position of the limb to achieve the goal of compression hemostasis.

[0018] (4) When the pressure needs to be removed, simply press the elastic locking tongue manually. After the locking platform disengages from the lock, the cantilever rod will rise and move away from the pressure position under the elastic force of the torsion spring. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] like Figures 1-9 As shown, the present invention proposes an interventional nursing device for vascular surgery, including a torque limiting component 1, a lifting and compression component 2, a cantilever support component 3, a quick unlocking component 4, and a bottom support component 5. The torque limiting component 1 is rotatably mounted on the lifting and compression component 2, which is located at the end of the cantilever support component 3. The cantilever support component 3 is located on one side of the bottom support component 5, and the quick unlocking component 4 is located on the cantilever support component 3. The torque limiting component 1 can limit the upper limit of the torque applied to the nut 22, thereby automatically unloading the force through its own slippage when the torque is too large, thus avoiding the problem of excessive pressure on the target position.

[0025] The torque limiting assembly 1 includes a drive disc 12, a driven disc 13, and a steel ball 14. The drive disc 12 and the driven disc 13 are capable of relative rotation and axial sliding. The steel ball 14 is located between the drive disc 12 and the driven disc 13. When the steel ball 14 is engaged in the groove of the drive disc 12 and the driven disc 13, the drive disc 12 and the driven disc 13 are relatively stationary. When the steel ball 14 rolls between the drive disc 12 and the driven disc 13, the drive disc 12 and the driven disc 13 move relative to each other.

[0026] The torque limiting assembly 1 also includes a handle 11 and a spring 15. The handle 11 is provided with a guide groove 111, and the drive disc 12 is provided with a guide part 121 that matches the guide groove 111. The drive disc 12 is engaged and slidably disposed in the guide groove 111 through the guide part 121. Spring 15 is located between handle 11 and drive disc 12.

[0027] The steel ball 14 is located in the grooves of the driving disc 12 and the driven disc 13. The rotational motion of the driving disc 12 is transmitted to the driven disc 13 through shearing force. When the reaction force of the shearing force on the driving disc 12 is greater than the elastic force of the spring 15, the driving disc 12 and the driven disc 13 will move away from each other and slip through the rolling of the steel ball 14, thereby achieving the technical purpose of setting the upper limit of torque.

[0028] The lifting and pressing assembly 2 includes a guide member 21 and a screw 23. The guide member 21 is provided with a guide rod 211, which is engaged and slidably disposed in the cantilever support assembly 3. The screw 23 is provided with a pressing plate 231, and the guide member 21 is fixedly connected to the pressing plate 231.

[0029] The lifting and pressing assembly 2 also includes a nut 22 and a pressing liner 24. The nut 22 is rotatably mounted in the cantilever support assembly 3. The driven plate 13 is fixed to the nut 22. The screw 23 and the nut 22 are connected by a thread. The pressing liner 24 is located at the bottom of the pressing plate 231.

[0030] The cantilever support assembly 3 includes a fixed bracket 31, a cantilever rod 32, and a hinge shaft 33. The fixed bracket 31 is mounted on the bottom support assembly 5, the hinge shaft 33 is fixedly connected to the fixed bracket 31, the cantilever rod 32 is rotatably mounted on the hinge shaft 33, the guide rod 211 is engaged and slidably mounted at the end of the cantilever rod 32, and the nut 22 is rotatably mounted at the end of the cantilever rod 32.

[0031] The cantilever support assembly 3 also includes a torsion spring 34, the two ends of which are fixed to the fixed bracket 31 and the cantilever rod 32 respectively. Under the elastic force of the torsion spring 34, the cantilever rod 32 has an upward tendency.

[0032] By applying pressure to the target location of the limb through the longitudinal movement of the compression disc 231, the goal of compression hemostasis can be achieved.

[0033] The quick unlocking component 4 includes a latch 41 and a resilient locking tongue 42. The latch 41 is fixed to the lower part of the cantilever rod 32, and the resilient locking tongue 42 is fixed to the side of the fixed bracket 31. The end of the resilient locking tongue 42 is provided with a locking platform 421 that cooperates with the latch 41.

[0034] When the pressure needs to be removed, simply press the elastic locking tongue 42 manually. After the locking platform 421 disengages from the latch 41, the cantilever rod 32 will rise and move away from the pressure position under the elastic force of the torsion spring 34.

[0035] The bottom support assembly 5 includes a bottom bracket 51 and a bottom liner 52. The bottom liner 52 is disposed in the bottom bracket 51, and the fixing bracket 31 is fixed to the side of the bottom bracket 51.

[0036] In practical use, first place the limb that needs to be compressed to stop bleeding on the bottom liner 52, and then manually flip the cantilever 32 downward. During the flipping process, the latch 41 will first abut against the slope of the locking platform 421 and push the elastic locking tongue 42 to bend inward. When the cantilever 32 is flipped to the horizontal position, the locking platform 421 springs back and locks into the latch 41. The torsion spring 34 causes the cantilever 32 to tend to tilt upwards, and the locking platform 421 restricts the tilting behavior of the cantilever 32, so the cantilever 32 will remain in a horizontal position.

[0037] Then manually rotate handle 11. In the initial state, the active plate 12 and the driven plate 13 are connected by steel ball 14. Therefore, when handle 11 is rotated, it will drive nut 22 to rotate through active plate 12 and driven plate 13. Through the thread transmission between nut 22 and screw 23, it will drive pressure plate 231 to move down until the pressure liner 24 abuts against and presses the target position.

[0038] As the handle 11 continues to rotate, the pressure of the inner liner 24 on the limb increases, and the rotational resistance of the nut 22 also increases. The steel ball 14 is located in the groove of the active plate 12 and the driven plate 13. The rotational motion of the active plate 12 is transmitted to the driven plate 13 through shearing force. When the reaction force of the shearing force on the active plate 12 is greater than the elastic force of the spring 15, the active plate 12 and the driven plate 13 will move away from each other and slip due to the rolling of the steel ball 14. At this time, the continued rotation of the handle 11 will not cause the driven plate 13 and nut 22 to rotate, thus achieving the technical purpose of setting the upper limit of torque and avoiding the problem of excessive pressure.

[0039] When unlocking is required, simply press the elastic locking tongue 42 manually to separate the locking platform 421 from the latch 41. The cantilever rod 32 will then immediately flip upward under the elastic force of the torsion spring 34, causing the pressure liner 24 to quickly move away from the target position.
