Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Cerebrovascular diseases are now considered a major threat to human health, and interventional therapy has become an important treatment method. When using a fixed nursing stent, the purpose, method, and importance of its use should be explained to the patient and their family beforehand to reduce the patient's anxiety and enable them to better cooperate with subsequent procedures. Patients should be informed that they should promptly inform medical staff if they experience any discomfort during use.

[0030] I. Intraoperative placement:

[0031] Positioning: When patients return to their ward after surgery, they are usually in a supine position. Medical staff should gently assist patients in straightening the limb on the puncture side, avoiding bending or excessive movement to reduce the risk of bleeding at the puncture site. At the same time, ensure that other parts of the body are kept comfortable and naturally positioned; soft pillows can be placed under pressure points such as the lower back and neck.

[0032] Stent fixation: Place the cleaned and disinfected nursing stent stably in a suitable position next to the bed, so that the fixed end of the stent is close to the patient's puncture side limb.

[0033] Slowly lift the patient's limb and place it into the groove or fixation area of ​​the stent, ensuring a tight fit between the limb and the stent, especially providing good support around the puncture site to avoid pressure on the wound. For patients with punctures in the groin, the stent height should be adjusted to comfortably support the thigh without affecting blood circulation; for patients with punctures in the wrist, the stent should precisely fix the wrist to maintain its functional position.

[0034] Based on the patient's comfort and condition, use the fixation straps provided on the stent to appropriately fix the limb. The fixation straps should not be too tight, just enough to allow one finger to be inserted, to prevent affecting blood circulation, while ensuring that the limb does not shift arbitrarily.

[0035] II. Postoperative care and adjustment:

[0036] Regular check-ups: Within one hour post-surgery, medical staff should check the stent fixation every 15 minutes, checking for loosening of the fixation straps, limb displacement, bleeding at the puncture site, or other abnormalities. The check-up interval can then be gradually increased, to once an hour after four hours post-surgery, to ensure patient safety.

[0037] Observe the patient's peripheral blood circulation, such as the color, temperature, and capillary refill time of the fingers or toes. If the peripheral extremities are found to be cold, pale, or the swelling is worsening, the brace should be adjusted or the fixation band loosened immediately, and the doctor should be notified if necessary.

[0038] Angle and height adjustment: Based on patient comfort feedback, the angle of the stent can be adjusted appropriately 2-3 hours after the procedure, such as raising the leg stent slightly by 15-30 degrees to promote venous return and reduce limb swelling. However, each adjustment should not be too large, and the operation should be slow and gentle to avoid causing patient discomfort or affecting the healing of the puncture site.

[0039] For special patients who are tall or short, if the initial support height is found to be unsuitable and affects the patient's rest or limb extension, it should be fine-tuned in a timely manner to ensure that the patient is in a comfortable state.

[0040] Cleaning and maintenance: Wipe the stent surface with a clean, damp cloth at least once a day to remove stains and dust and keep the stent clean. If the stent comes into contact with the patient's secretions, blood, etc., it should be disinfected immediately using a suitable medical disinfectant, following standard procedures to prevent the growth of bacteria.

[0041] Stent Removal: When the doctor determines that the patient's condition meets the criteria for stent removal, such as good healing of the puncture site, no risk of bleeding, and near-normal limb movement, medical staff should carefully loosen the fixation straps and slowly remove the patient's limb from the stent, avoiding collisions or excessive force. After removal, the stent should be thoroughly cleaned and disinfected again and stored for future use.

[0042] III. Structural Analysis of Fixed Nursing Frame:

[0043] 1. Main frame materials: These are mostly made of medical-grade polymer materials or lightweight alloys, possessing good biocompatibility. They ensure sufficient strength and support without triggering an excessive immune response in the body. For example, some polyester materials are malleable, allowing for easy adjustment according to the patient's limb shape.

[0044] 2. Fixation component design: such as Velcro, buckles, etc., can flexibly adjust the tightness to adapt to the different limb sizes of patients, ensuring that the bracket fits tightly without excessive pressure, ensuring the fixation effect while improving patient comfort.

[0045] IV. The application of mechanical principles in the use of support structures:

[0046] 1. Pressure dispersion mechanism: The stent evenly disperses the external force generated by limb movement to a larger area, avoiding excessive local pressure that could damage the puncture point or implantation site, protecting the vascular anastomosis, and maintaining the stability of the intravascular stent position.

[0047] 2. Principle of limiting displacement: Based on human anatomy and kinesiology, the stent restricts improper movement of the limb from multiple angles, preventing traction on blood vessels due to sudden flexion, extension, twisting and other movements, reducing the risk of vascular intima tearing and stent displacement, and ensuring the effectiveness of interventional treatment.

[0048] V. Bio-interaction between scaffolds and human tissues:

[0049] 1. Promotes local blood circulation: The well-designed stent structure will not obstruct the return of superficial veins, and its moderate elastic compression can also assist the blood flow of deep arteries, prevent blood stasis, and reduce the probability of thrombosis.

[0050] 2. Tissue compatibility guarantee: The surface of the material is specially treated to reduce protein adsorption and cell adhesion, inhibit inflammatory response, and allow the scaffold to be in contact with the skin and subcutaneous tissue for a long time without causing adverse reactions such as redness, swelling and ulceration, creating favorable conditions for postoperative recovery.

[0051] VI. Clinical Application Case Analysis:

[0052] 1. Multiple patients who underwent cerebrovascular interventional procedures were selected and divided into a group receiving fixed nursing stents and a control group receiving traditional nursing care.

[0053] 2. Comparative observation indicators: These included puncture site healing time, restenosis rate, and patient comfort score. Results showed that the stent group had significant advantages in terms of shorter healing time, lower restenosis rate, and improved comfort, directly reflecting the effectiveness of the stent.

[0054] VII. Conclusion: Postoperative fixation stents for cerebrovascular diseases, based on their scientifically sound structural design, ingenious application of mechanical principles, and excellent bio-interaction characteristics, play a crucial role in ensuring surgical outcomes and promoting patient recovery. Future research should focus on further optimizing stent design, incorporating more clinical practice, and expanding their application scope to bring greater benefits to patients with cerebrovascular diseases.

[0055] With continuous advancements in materials science, biomechanics, and other fields, it is hoped that intelligent and personalized nursing stents can be developed to monitor patient status in real time and automatically adjust fixation parameters, thus opening a new chapter in postoperative care for cerebrovascular interventional procedures.

[0056] Please see Figure 1-4 As shown, this embodiment provides a fixation and nursing stent after interventional treatment for cerebrovascular diseases, including: a support assembly, on which two movable plates 4 are rotatably coupled;

[0057] Each of the two movable plates 4 has three constraint components installed on its inner side. A footrest 18 is installed on the side of the movable plate 4 away from the support components. A sleeve is installed on the lower side of the movable plate 4, and a winding rod 16 corresponding to the three constraint components rotates inside the sleeve. One end of each constraint component is installed on the side of the winding rod 16. A first bevel gear 14 is installed on one end face of the winding rod 16. A sleeve 9 is embedded in one side of the sleeve, and a second bevel gear 13 meshes with the first bevel gear 14 on one end face of the sleeve 9. Rotatably fitted inside the sleeve, the second bevel gear 13 has a first tooth groove on one end face, and a spur gear 12 slides elastically in the first tooth groove. The sleeve 9 has a second tooth groove on one end face that matches the spur gear 12. A limiting ring is installed around the second tooth groove, and the limiting ring is located on one end face of the spur gear 12. One end face of the spur gear 12 is located in the first tooth groove, and the spur gear 12 meshes with the first tooth groove and the second tooth groove. One end face of the spur gear 12 has a square groove, and an adjusting component corresponding to the square groove is elastically fitted on the sleeve 9.

[0058] One application of this embodiment is as follows: When a patient needs care, the patient can lie or sit on the support assembly, then open the restraint assembly and place their legs on the movable plate 4 and their feet on the footrest 18. After placement, the restraint assembly can be re-fastened. The patient can then adjust the tightness of the restraint assembly according to the thickness of their legs. This process requires first pressing the adjusting assembly towards the sleeve 9 so that one end of the adjusting assembly is inserted into the square groove. At the same time, the adjusting assembly pushes the spur gear 12 out of the second tooth groove and fully retracts into the first tooth groove. Then, the patient can rotate the adjusting assembly. The rotation of the adjusting assembly drives the spur gear 12 to rotate. The rotation of the spur gear 12, through meshing with the first tooth groove, drives the second bevel gear 13 to rotate. The rotation of the second bevel gear 13 drives the first bevel gear 14 to rotate. A bevel gear 14 rotates, driving a winding rod 16 to rotate. The winding rod 16 then winds up the restraint assembly, adjusting its tightness. Once the patient has adjusted the restraint assembly to the appropriate tightness, they can release the pressure on the adjusting assembly. The adjusting assembly then quickly resets under elastic force, releasing its pressure on the spur gear 12 and disengaging it from the square slot. The spur gear 12 then resets under elastic force, partially engaging with the second tooth groove and fitting against the limiting ring. This allows the spur gear 12 to mesh simultaneously with both the first and second tooth grooves, restricting the rotation of the second bevel gear 13 and thus securing the adjusted restraint assembly. Simultaneously, the patient can move their legs to rotate the movable plate 4 and footrest 18 for rehabilitation training. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0059] The movable plate 4, in conjunction with the support assembly, allows patients to adjust the position of their legs and feet by rotating it when lying down or sitting, reducing the probability of leg numbness and facilitating rehabilitation training. The first tooth groove engages with the spur gear 12, allowing the spur gear 12 to rotate and drive the second bevel gear 13. The second tooth groove, in conjunction with the spur gear 12, limits the movement of the second bevel gear 13, and consequently, the first bevel gear 14 and the winding rod 16, reducing the probability of the restraint assembly loosening after adjustment. The coordination between the restraint assembly and the adjustment assembly allows patients to adjust the tightness of the restraint assembly according to the size of their legs, thereby improving the fit and comfort of the device.

[0060] like Figure 1 As shown, the support assembly of this embodiment includes a back plate 1, with two guardrails 2 installed on the upper side of the back plate 1. An extension plate 19 is installed on one side of the back plate 1, and an movable groove corresponding to the movable plate 4 is provided. The movable plate 4 is rotatably fitted on the upper side of the extension plate 19. The two guardrails 2 help to reduce the probability of the patient falling off the back plate 1, and the movable groove helps to save material for the width of the extension plate 19.

[0061] like Figure 1 , 2 As shown, the extension plate 19 of this embodiment is provided with a protruding post on its upper side, and a first bearing 3 is provided around the protruding post. The movable plate 4 is provided around the first bearing 3. The first bearing 3 cooperates with the protruding post to improve the stability of the movable plate 4 when it rotates.

[0062] like Figure 4 As shown, the adjustment assembly of this embodiment includes a drive rod 10, a sliding plate 11 is mounted on the periphery of the drive rod 10, the sliding plate 11 slides elastically within the sleeve 9, a knob 15 is mounted on one end face of the drive rod 10, and a square block is mounted on the end face of the drive rod 10 away from the knob 15. The knob 15 is located on one end face of the sleeve 9, and the square block is slidably fitted within the sleeve 9. The square block is adapted to the square groove. By cooperating with the sliding plate 11, the probability of the drive rod 10 falling out of the sleeve 9 is reduced. The knob 15 facilitates the rotation of the drive rod 10 and the square block.

[0063] like Figure 4 As shown, in this embodiment, one end face of the sleeve 9 is provided with a first sliding groove corresponding to the drive rod 10. The first sliding groove is connected to the second tooth groove. A second sliding groove corresponding to the sliding plate 11 is provided around the first sliding groove. A spring is installed between the end faces of the sliding plate 11 and the second sliding groove. The spring is located around the drive rod 10. The spring facilitates pulling the sliding plate 11 to move away from the spur gear 12, so that when the knob 15 is released, the square block is quickly reset and pulled out from the square groove.

[0064] like Figure 3 , 4 As shown, in this embodiment, a second bearing is installed on the circumference of the sleeve 9, and a first fixing ring is installed on the circumference of the second bearing. The first fixing ring is installed on one end face of the second bevel gear 13. The first fixing ring cooperates with the second bearing, which helps to reduce the probability of the second bevel gear 13 disengaging from the sleeve 9, thereby improving the stability of the second bevel gear 13 when rotating.

[0065] like Figure 1 , 2As shown, the restraint assembly in this embodiment includes a connecting strap installed on one side of the movable plate 4. One end of the connecting strap is connected to a buckle 5, and a restraint strap 6 is connected to the buckle 5. Four coiled ropes 7 are installed on one side of the restraint strap 6, and one end of the coiled ropes 7 is installed on the side of the winding rod 16. The three restraint straps 6 on the movable plate 4 decrease in length from the back plate 1 to the footrest 18, thereby corresponding to the thigh, knee, and calf positions of the human body, respectively. The restraint straps 6 are made of elastic material, which can better fit and fix the patient's legs. The buckle 5 is a common buckle on the market. The buckle includes a male buckle and a female buckle. The female buckle is connected to the connecting strap, and the male buckle is connected to the restraint strap 6. The male buckle can be adjusted on the restraint strap 6. When in use, the male buckle is inserted into the female buckle to complete the connection. When disassembling, the spring pieces on both sides of the male buckle need to be squeezed. The buckle 5 makes it easy for the patient to fix and disassemble the restraint strap 6 and the connecting strap when using it. It is beneficial for the patient to place their legs directly on the movable plate 4 for fixation, which improves the convenience of the patient's use and reduces the difficulty of the patient's operation.

[0066] like Figure 2 As shown, the casing of this embodiment includes an adjustment box 8 corresponding to the winding rod 16, two protective shells, and three winding boxes 17. One side of each winding box 17 has a winding opening adapted to the winding rope 7. The adjustment box 8, protective shells, and winding boxes 17 are all installed on the lower side of the movable plate 4. A protective shell is installed between two adjacent winding boxes 17, and one winding box 17 is installed between the adjustment box 8 and the corresponding protective shell. The winding rod 16 laterally passes through the two winding boxes 17 and two protective shells located in the middle. The end of the winding rod 16 is rotatably fitted onto the edge... Inside the winding box 17 and the adjusting box 8, a third bearing is installed around the winding rod 16, and a second fixing ring is installed around the third bearing. The second fixing ring is installed on one side of the inner wall of one of the winding boxes 17. Through the cooperation of the adjusting box 8, the protective shell and the winding box 17, the probability of the winding rod 16 being affected during operation is reduced, and the safety of the winding rod 16 when rotating is improved. Through the cooperation of the second fixing ring and the third bearing, the stability of the winding rod 16 when rotating is improved, and the probability of the winding rod 16 and the first bevel gear 14 sliding laterally is reduced.
