Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a neurointerventional femoral artery puncture hemostasis nursing device. Background Technology

[0002] Femoral artery puncture is a routine approach in neurointerventional surgery, widely used in minimally invasive procedures such as cerebral angiography, intracranial aneurysm embolization, cerebral vascular stent implantation, and thrombectomy for acute ischemic stroke. Neurointerventional surgery requires systemic heparinization for anticoagulation during the procedure, and some patients require long-term dual antiplatelet therapy post-operatively. The risk of complications such as puncture site bleeding, subcutaneous hematoma, and retroperitoneal hematoma is relatively high; therefore, precise and stable pressure hemostasis post-operatively is crucial for ensuring surgical safety.

[0003] Currently used femoral artery puncture hemostasis devices have several drawbacks. First, after surgery and sheath removal, medical staff need to continuously apply manual pressure to the puncture site, which is time-consuming, labor-intensive, and significantly reduces clinical nursing efficiency. Prolonged manual pressure can easily lead to inaccurate pressure placement and unstable pressure due to hand fatigue, uneven pressure, misalignment, or loosening of the pressure. This can easily cause bleeding at the puncture site, subcutaneous hematoma, and in severe cases, induce serious complications such as pseudoaneurysms and retroperitoneal hematomas, greatly increasing the risk of improper pressure operation and resulting in poor hemostasis safety and stability. Second, existing hemostasis devices only provide postoperative hemostasis and pressure application, lacking a puncture guidance and positioning structure. Clinical puncture relies entirely on the experience of medical staff for manual operation, lacking mechanical guidance and constraints. The angle of needle travel and puncture depth cannot be standardized, easily leading to puncture point deviation, repeated punctures, and accidental vascular injury, increasing surgical trauma and the incidence of postoperative complications. Summary of the Invention

[0004] This invention provides a neurointerventional femoral artery puncture hemostasis nursing device to solve the technical problems of existing femoral artery puncture hemostasis nursing devices, such as lack of puncture guidance capability, reliance on long-term manual pressure, low work efficiency, high risk of puncture deviation and hemostasis failure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A neurointerventional femoral artery puncture hemostasis nursing device includes a main frame housing, a power pressure rod installed on the main frame housing, a sterile silicone pressure pad installed at the bottom of the power pressure rod, and two sets of rear stabilizing support frames symmetrically fixedly connected to the main frame housing, the two sets of rear stabilizing support frames being symmetrically arranged along the long side axis of the main frame housing;

[0007] An angle adjustment unit is assembled at the junction of the main frame housing and the rear stabilizing support frame. The angle adjustment unit includes a lateral adjustment screw rotation groove, which is located at the junction of the main frame housing and the rear stabilizing support frame. A lateral adjustment screw is rotatably installed inside the lateral adjustment screw rotation groove. A lateral adjustment frame is threaded onto the outer side of the lateral adjustment screw. A longitudinal adjustment frame is slidably assembled on the inner side of the lateral adjustment frame. A longitudinal fixing knob is inserted into the lateral adjustment frame and the longitudinal adjustment frame. An angle adjustment damping shaft is fixedly installed at the end of the longitudinal adjustment frame. A puncture needle guide groove is fixedly connected to the rotating end of the angle adjustment damping shaft.

[0008] Optionally, a lateral adjustment knob is fixedly mounted on one end of the lateral adjustment screw, and a lateral adjustment screw limit block is fixedly connected to the end of the lateral adjustment screw away from the lateral adjustment knob.

[0009] Optionally, a transverse adjusting screw limiting groove is provided at the junction of the main frame housing and the rear stabilizing support frame. The transverse adjusting screw limiting groove is connected to the transverse adjusting screw rotation groove, and the transverse adjusting screw limiting block slides within the transverse adjusting screw limiting groove.

[0010] Optionally, the top of the lateral adjustment frame is threaded through and fitted with a lateral fixing knob for locking and positioning; the lower half of the lateral adjustment frame has an arc-shaped structure, and the arc-shaped section has a lateral adjustment groove in the horizontal direction and a first longitudinal adjustment groove in the vertical direction.

[0011] Optionally, a longitudinal fixing knob is slidably inserted inside the transverse adjustment groove, and the longitudinal fixing knob can be horizontally slidably positioned along the transverse adjustment groove.

[0012] Optionally, a longitudinal adjustment frame is slidably mounted on the inner side of the first longitudinal adjustment slide, and a second longitudinal adjustment slide matching the first longitudinal adjustment slide is provided on the side wall of the longitudinal adjustment frame. The longitudinal fixing knob passes through the transverse adjustment slide and the second longitudinal adjustment slide to realize the longitudinal locking and positioning of the longitudinal adjustment frame.

[0013] Optionally, the bottom end of the main frame housing is rotatably connected to a pressure relief plate that conforms to the human leg, and the bottom end of the rear stabilizing support frame is rotatably connected to a rear stabilizing support plate. Both the rear stabilizing support plate and the pressure relief plate are configured as arc-shaped fitting structures that conform to the contour of the human thigh.

[0014] Optionally, strap connecting seats are fixedly provided on both sides of the main frame housing, and wide fixing straps for overall fixation are sleeved on the inner side of the strap connecting seats on both sides.

[0015] Optionally, the top of the main frame housing is fitted with operation buttons for controlling the start and stop of the device and adjusting the pressurization parameters.

[0016] Optionally, a power pressure rod is installed inside the main frame housing, and a hemostatic pressure block is fixedly connected to the bottom of the power pressure rod. A flexible, sterile silicone pressure pad is fitted on the outside of the hemostatic pressure block.

[0017] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0018] In the aforementioned scheme, a three-dimensional adjustment structure consisting of a lateral adjustment screw, a lateral adjustment frame, a longitudinal adjustment frame, and an angle-adjusting damping shaft can flexibly fine-tune the lateral position, longitudinal height, and puncture tilt angle of the puncture guide groove according to the patient's groin differences and femoral artery pulsation points. This precisely limits the needle's trajectory, angle, and puncture point. It overcomes the drawbacks of traditional punctures that rely entirely on the experience of medical personnel and lack mechanical guidance, effectively avoiding problems such as puncture point deviation, improper angle, repeated punctures, and accidental puncture of the vessel wall. This significantly improves the success rate of femoral artery puncture on the first attempt, reduces intraoperative complications such as vascular injury and subcutaneous hematoma, and lowers the difficulty of neurointerventional puncture procedures.

[0019] By using a main frame shell, a rear-mounted stabilizing support frame, a wide-width fixing strap, an arc-shaped pressure-relieving plate, and a rear-mounted stabilizing support plate to form an integrated support and fixation structure, it can be pre-fixed to the outside of the patient's puncture area after preoperative disinfection and draping, eliminating the need to wait for the surgery to end and the sheath to be removed before temporarily assembling the device. When the arterial sheath is removed after the surgery, the built-in hemostatic and pressure-applying component can be directly activated to achieve precise pressure hemostasis, eliminating the need for medical staff to continuously apply pressure to the puncture site after sheath removal, which is a traditional technique. This greatly shortens the postoperative hemostasis preparation time, reduces the manpower required for medical staff, alleviates clinical workload, and effectively improves the efficiency of hemostasis nursing after neurointerventional surgery. It is especially suitable for rapid treatment scenarios such as emergency cerebral infarction thrombectomy and emergency aneurysm embolization.

[0020] Precise lateral fine-tuning is achieved through a threaded transmission of a lateral adjusting screw, while stepless longitudinal position adjustment is realized through lateral, first, and second longitudinal adjusting slides. Rigid locking after adjustment is achieved with lateral and longitudinal fixing knobs. Simultaneously, an angle-adjustable damping shaft allows for arbitrary adjustment of the puncture angle and instant damping positioning, eliminating springback and offset. This structure is adaptable to the operational needs of medical personnel with different body types, groin depths, and clinical puncture habits. It offers a wide adjustment range, high positioning accuracy, and strong structural stability, effectively solving the defects of traditional guide devices such as adjustment jamming, loose positioning, and poor adaptability. The overall versatility and clinical adaptability of the device are significantly improved.

[0021] By incorporating an arc-shaped pressure-relieving plate and two rear-mounted stabilizing support plates, the device perfectly conforms to the physiological contours of the human thigh and groin. Combined with a wide bandage for overall fixation, it ensures even force distribution and a strong fit, effectively preventing displacement and slippage of the device during and after surgery, guaranteeing accurate puncture guidance and preventing deviation of the postoperative pressure point. Simultaneously, the built-in hemostatic and pressure-applying assembly, consisting of a power pressure rod, hemostatic pressure block, and sterile silicone pressure pad, precisely targets and stably applies pressure to the intravascular puncture site. The pressure is uniform and controllable, avoiding the fatigue, uneven force, pressure deviation, and inconsistent tightness associated with traditional manual pressure application. This effectively prevents high-risk complications such as puncture site bleeding, subcutaneous hematoma, pseudoaneurysm, and retroperitoneal hematoma. It is particularly suitable for high-bleeding scenarios in neurointerventional patients undergoing intraoperative heparinization and postoperative dual antiplatelet therapy, significantly improving the safety and stability of postoperative hemostatic care.

[0030] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides a neurointerventional femoral artery puncture hemostasis nursing device, including a main frame housing 1. Two sets of rear stabilizing support frames 2 are symmetrically fixedly connected to the main frame housing 1, and the two sets of rear stabilizing support frames 2 are symmetrically arranged along the long axis of the main frame housing 1. The main frame housing 1 is the main load-bearing structure of the device. The two sets of rear stabilizing support frames 2 are symmetrically fixedly installed along the long axis of the main frame housing 1 to form a symmetrical support frame structure, which can effectively distribute the overall pressure of the device and avoid tilting due to unilateral force. An angle adjustment unit is assembled at the junction of the main frame housing 1 and the rear stabilizing support frames 2. The angle adjustment unit is used to realize the three-dimensional precise adjustment of the lateral displacement, longitudinal lifting, and angle pitch of the puncture needle guide structure.

[0032] like Figures 3-6 As shown, the angle adjustment unit includes a lateral adjustment screw rotation groove 7, a lateral adjustment screw 8, a lateral adjustment knob 9, a lateral adjustment frame 10, a lateral fixing knob 11, a longitudinal fixing knob 12, a longitudinal adjustment frame 13, an angle adjustment damping shaft 18, and a puncture needle guide groove 14. The lateral adjustment screw rotation groove 7 is located at the junction of the main frame housing 1 and the rear stabilizing support frame 2, providing a stable rotation limit space for the lateral adjustment screw 8. The lateral adjustment screw 8 is rotatably mounted inside the lateral adjustment screw rotation groove 7. One end of the lateral adjustment screw 8 is fixed to the lateral adjustment knob 9, and the other end is fixed to the lateral adjustment screw limit block 19 (e.g., ...). Figure 6(As shown). A transverse adjusting screw limiting groove 20, which communicates with the transverse adjusting screw rotation groove 7, is opened at the corresponding position of the main frame housing 1, so that the transverse adjusting screw limiting block 19 slides and is limited in the groove, effectively preventing the transverse adjusting screw 8 from over-traveling, slipping out, and ensuring that the adjustment stroke is safe and controllable. The transverse adjusting screw 8 is threadedly sleeved on the outer side of the transverse adjusting frame 10. Through the thread transmission principle, medical staff can drive the transverse adjusting screw 8 to rotate forward and reverse by rotating the transverse adjusting knob 9, thereby driving the transverse adjusting frame 10 to make horizontal linear displacement along the transverse adjusting screw 8, realizing precise transverse alignment and fine adjustment of the puncture guide structure. The lower half of the transverse adjusting frame 10 is provided with an arc-shaped adjusting base. The arc-shaped base has a transverse adjusting slide groove 21 in the horizontal direction and a first longitudinal adjusting slide groove 22 in the vertical direction. The longitudinal adjusting frame 13 is slidably assembled inside the first longitudinal adjusting slide groove 22. A matching second longitudinal adjustment groove 23 is provided on the side wall of the longitudinal adjustment frame 13. The longitudinal fixing knob 12 is set through the transverse adjustment groove 21 and the second longitudinal adjustment groove 23, and the longitudinal fixing knob 12 can be tightened or loosened. The longitudinal fixing knob 12 in this embodiment can adopt a bolt, nut structure, or other locking structure. The bolt passes through the transverse adjustment groove 21 and the second longitudinal adjustment groove 23 and the nut is tightened. By loosening the longitudinal fixing knob 12, the longitudinal adjustment frame 13 can be adjusted up and down in the vertical direction and slid and finely adjusted in the horizontal direction. After adjusting to the target position, the longitudinal fixing knob 12 is locked to achieve rigid locking of the longitudinal height and horizontal offset position, without loosening or displacement. At the same time, a transverse fixing knob 11 is provided at the top of the transverse adjustment frame 10. The transverse fixing knob 11 is threaded on the transverse adjustment frame 10, and the bottom of the transverse fixing knob 11 can abut against the adjusting screw 8, which can perform secondary locking and positioning of the overall position of the transverse adjustment frame 10, further improving the overall stability of the adjustment structure.

[0033] like Figure 6 As shown, an angle-adjustable damping shaft 18 is fixedly installed at the front end of the longitudinal adjustment frame 13. The rotating end of the angle-adjustable damping shaft 18 is fixedly connected to the puncture needle guide groove 14. The puncture needle guide groove 14 adopts an arc-shaped groove structure, which can stably limit the external section of the puncture needle and standardize the puncture needle insertion trajectory. Utilizing the constant resistance characteristic of the damping shaft, the puncture needle guide groove 14 can be arbitrarily adjusted in the range of 0° to 60°, and can achieve instant suspension and locking at any angle without rebound or deviation. It can accurately match the standard needle insertion angle of 30° to 45° for neurointerventional femoral artery puncture, completely solving the problems of arbitrary angle, uncontrollable trajectory, and large deviation in landing point of traditional manual puncture.

[0034] like Figure 1 and Figure 2As shown, the device in this embodiment includes a main frame housing 1, a rear-mounted stabilizing support, a multi-dimensional angle adjustment guide unit, and a built-in hemostasis and pressure assembly. The hemostasis and pressure assembly is installed inside the main frame housing 1. The assembly includes a power pressure rod 15 installed within the main frame housing 1. A hemostasis pressure block 16 is mounted at the bottom of the power pressure rod 15, and a sterile silicone pressure pad 17 is mounted at the bottom of the hemostasis pressure block 16. In this embodiment, the power pressure rod 15 can be a pneumatic support rod or similar mechanism that provides linear motion. The power pressure rod 15 provides the power for vertical sliding, thereby pushing the hemostasis pressure block 16 to move vertically up and down, allowing the sterile silicone pressure pad 17 at the bottom of the hemostasis pressure block 16 to precisely adhere to and compress the puncture site of the inguinal blood vessel, thus achieving the effect of pressure-based hemostasis.

[0035] The pressure relief plate 4 is rotatably mounted on the bottom end of the main frame housing 1, and the rear stabilizing support plate 3 is rotatably mounted on the bottom end of the rear stabilizing support frame 2. Both the rear stabilizing support plate 3 and the pressure relief plate 4 adopt an arc-shaped curved surface structure that matches the anatomical curvature of the human thigh and groin, which can fit the patient's skin over a large area, avoiding the problems of strong local pressure and obvious pressure marks. At the same time, it can adapt to the leg contours of patients of different weights and sizes, significantly improving the fit and overall stability of the device.

[0036] like Figure 2 As shown, strap connecting seats 24 are fixedly installed on the left and right sides of the main frame housing 1. Wide fixing straps 5 are sleeved on the inner side of the strap connecting seats 24. The wide wrap-around strap structure can securely pre-fix the entire device to the outside of the patient's groin puncture area, realizing the overall installation logic of pre-installation before operation, stable placement during operation, and no need for reassembly after operation. An operation button 6 is embedded at the top of the main frame housing 1. The operation button 6 is electrically connected to the power pressure rod 15, which allows medical staff to control the start and stop of the power pressure rod 15 with one button, making operation convenient.

[0037] The working process of the neurointerventional femoral artery puncture hemostasis nursing device provided by the present invention is as follows:

[0038] Before the puncture procedure, after the medical staff disinfects and drapes the patient's groin area, during puncture positioning, the medical staff first palpates to determine the midpoint of the inguinal ligament. The highest point of the femoral artery trunk is located deep at this point, which is determined as the femoral artery puncture point. Then, the puncture point of the skin puncture needle is located 1-2 cm below the midpoint of the inguinal ligament. The device is then pre-fixed to the outside of the puncture area of ​​the patient's groin using a wide fixing strap 5. At this time, the sterile silicone compression pad 17 is directly above the femoral artery puncture point. The entire device is pre-laid, suspended without pressure, does not obstruct the puncture field of view, and does not affect the intraoperative operation. There is no need to wait for temporary assembly after the operation, which greatly saves the time for postoperative hemostasis preparation.

[0039] By rotating the horizontal adjustment knob 9, sliding the vertical adjustment bracket 13, and rotating the damping shaft angle, the center of the puncture needle guide groove 14 is precisely aligned with the vascular puncture inlet. At the same time, the axis of the puncture needle guide groove 14 forms a standard needle insertion angle of 30° to 45° with the patient's skin. After locking all the adjustment knobs, the needle can be inserted along the puncture needle guide groove 14. The groove guides the puncture needle throughout the entire process, ensuring a stable needle insertion angle and a regular puncture trajectory, greatly improving the success rate of a single puncture and effectively avoiding adverse situations such as repeated punctures, accidental vascular injury, and subcutaneous bleeding.

[0040] After the neurointerventional surgery is completed, heparin is discontinued, and the conditions for sheath removal are met, medical staff activate the built-in hemostatic and pressurizing component of the device via the operation button 6 at the top of the main frame housing 1. The power lever 15 provides stable vertical driving force, pushing the hemostatic pressure block 16 vertically downwards. This allows the sterile silicone pressure pad 17 at the bottom of the hemostatic pressure block 16 to precisely adhere to and compress the internal opening of the groin vessel puncture site, providing appropriate pressure. Then, the arterial sheath is removed, eliminating the need for continuous manual pressure on the puncture site. The sterile silicone pressure pad 17 is made of flexible, sterile medical-grade silicone material, conforming to the skin and providing uniform pressure. It prevents excessive local pressure leading to ischemia or insufficient pressure causing bleeding, and can continuously, stably, and evenly apply pressure to seal the punctured vessel tear, completely replacing traditional manual pressure operations.

[0041] During postoperative care, the pressure is gradually reduced after the hemostasis time is achieved. At regular intervals, the built-in hemostatic pressure component of the device is activated by operating button 6, causing the power pressure rod 15 to move upward relative to the main frame housing 1. This reduces the pressure of the sterile silicone pressure pad 17 at the bottom of the hemostatic pressure block 16 on the internal puncture site of the patient's inguinal vessel. The process continues only after observing for any bleeding. The device relies on a symmetrical rear-mounted stable support frame 2 and an arc-shaped fitting structure, ensuring a secure and stable overall fixation that is not easily displaced. The device uses mechanical positioning and electrically controlled pressure throughout the entire process, eliminating problems such as human fatigue, pressure deviation, and unstable force. It can effectively avoid high-risk complications such as subcutaneous hematoma, puncture site bleeding, pseudoaneurysm, and retroperitoneal hematoma, and is particularly suitable for high-risk bleeding scenarios in neurointerventional patients undergoing intraoperative heparinization and postoperative dual antiplatelet therapy.

[0042] In the aforementioned solution, this device, through its integrated structural design, simultaneously addresses industry pain points such as the lack of puncture guidance, high risk of puncture deviation, cumbersome post-operative assembly, reliance on prolonged manual pressure, low nursing efficiency, and poor hemostatic stability associated with traditional devices. The device boasts high adjustment precision, excellent positioning stability, comfortable fit, and simple and convenient operation. It can simultaneously meet the dual clinical needs of precise puncture in neurointerventional surgery and safe hemostasis post-operatively. It is suitable for neurointerventional patients of different ages, body types, and surgical procedures, demonstrating strong versatility and high clinical application value.

[0043] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
