Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to a puncture stabilization component for cardiovascular medicine. Background Art

[0002] Cardiac interventional surgery is the most common surgery in cardiovascular medicine. It is an advanced medical technology, usually referring to heart stent surgery or cardiac angiography. It can be used to treat diseases such as angina pectoris and myocardial infarction, as well as to inject contrast agents to observe the condition of the heart and blood vessels. Compared with open-chest surgery, it has the advantages of less trauma and faster recovery.

[0003] Cardiac interventional surgery generally involves inserting an interventional needle into the artery, then sending a catheter through the artery into the heart, and then performing subsequent treatment or examination items. For example, the end of the catheter is connected to the opening of the coronary artery, and contrast agent is injected into the heart through the catheter. The specific condition of the coronary artery can be seen under X-ray, and the appropriate treatment plan can be selected based on the examination results; or a stent can be placed in the blood vessels in the heart through a catheter to treat diseases such as angina pectoris, myocardial infarction, and cardiovascular stenosis.

[0004] Interventional puncture needles generally contain a needle body and a needle handle. The operator adjusts the angle and depth of the needle by holding the needle handle. This type of puncture needle is flexible in puncture, but due to the small hand-holding area and the thin handle of the interventional needle, it is easy to hold the needle unstable. Cardiac interventional surgery generally chooses the femoral artery as the puncture blood vessel. Under ultrasound guidance, the puncture needle is first inserted into the femoral artery, and then the hand-held posture is maintained before the catheter and guide wire are inserted. Because the hand-held posture needs to be maintained for a long time, and due to technical reasons of the operator, the needle is held unstable and shakes or deflected, resulting in puncture failure or bleeding. The stabilization devices in the existing technology are generally used on smoother skin surfaces. There are fewer stabilization devices specifically for femoral vein puncture. The operation flexibility is general and cannot be fine-tuned, which easily affects the operation of medical workers. For obese patients, the groin puncture area often forms wrinkles due to fat accumulation, and the puncture area cannot be fully exposed. The operator needs to assist in stretching the skin at the groin, which puts a burden on medical staff. Therefore, a new technology is needed to improve this situation. Summary of the Invention

[0005] In response to the above-mentioned problems in the prior art, the present invention provides a puncture stabilization component for cardiovascular medicine, which is a stabilization device specially designed for femoral artery puncture. It increases the holding area and needle holding stability of the interventional needle handle, and can replace the operator to maintain the holding state for a long time, avoiding the problem of puncture failure or bleeding caused by unstable needle holding due to technical reasons of the operator, such as shaking or deviation. It has high flexibility and can be finely adjusted without affecting the operation of medical workers. It can replace the operator to hold open the skin in the groin where fat accumulation cannot be fully exposed in the puncture area, thereby reducing the burden on medical staff.

The concave profile of the upper support plate and the upper connection area of ​​the ends of the two adjacent support seats are S1, and the concave profile of the lower support plate and the lower connection area of ​​the ends of the two adjacent support seats are S2, S1>S2;

[0009] The upper surface of the upper support plate is connected to the lower part of the connecting hose, and the upper part of the connecting hose is connected to the outer surface of the sleeve. The connecting hose is deformable, and the deformable connecting hose is a qualitatively deformable connecting hose. The sleeve is arranged horizontally and is a hollow annular body. The inner cavity contour of the sleeve is consistent with the contour of the interventional needle handle, and the inner cavity of the sleeve forms an interference fit with the outer surface of the needle handle of the interventional needle.

[0010] When the traction belt is in a taut state, the lower surface of the other end of the traction belt is fixed to the skin surface of the upper end of the groin by adhesive connection, the support plate undergoes elastic deformation, the other end of the upper support plate bulges upward to form a convex arc surface, and the other end of the lower support plate bulges downward to form a concave arc surface.

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0028] A puncture stabilization component for cardiovascular medicine includes a thickening block 1. The lower surface of the thickening block 1 is a concave arc surface. The concave arc surface can make the lower surface of the thickening block completely close to the skin of the front end of the human thigh, thereby assisting in the fixation of the thickening block 1. The horizontal longitudinal side of the thickening block 1 is connected with one end of the adjusting belt 2. The adjusting belt 2 is arranged vertically and longitudinally. The other end of the adjusting belt 2 is connected to the other horizontal longitudinal side of the thickening block 1 through a ring. The adjusting belt 2 is a flexible adjusting belt 2. The thigh circumference at the fixing point of the thickening block 1 is adjusted by the flexible adjusting belt 2, thereby fixing the position of the thickening block 1 and increasing the friction between the fixing block and the skin.

[0029] In this embodiment, the transverse side of the thickening block 1 is connected to one end of the two support plates, the support plates are arranged transversely, and the two support plates are arranged longitudinally. The support plates are elastic support plates, and the elastic support plates are hard elastic support plates. When the hard elastic support plates are elastically deformed, sufficient supporting force can be generated to open the wrinkles in the groin area 9.

[0030] In this embodiment, the support plate includes an upper support plate 3a and a lower support plate 3b, and the other ends of at least two support plates are respectively connected to support seats 4 on both sides. The end of the corner seat is a convex angle structure. The convex angle structure allows the support seat 4 to smoothly penetrate into the folds of the groin 9 without the need for other external force assistance, while reducing resistance. The upper and lower parts of the other end of the support seat 4 are respectively connected to the upper support plate 3a and the lower support plate 3b.

[0031] In this embodiment, the cross-sectional edges of the upper support plate 3a, the lower support plate 3b, the support seat 4, and the thickened block 1 form a triangle. When the outer surface of the convex corner structure of the support seat 4 is pressed, and at the same time, the thickened block 1 is squeezed by the force to cause the upper support plate 3a and the lower support plate 3b to elastically deform, the upper support plate 3a undergoes elastic deformation upward, and the lower support plate 3b undergoes elastic deformation downward, thereby achieving the effect of stretching the wrinkled skin in the groin area 9.

[0032] In this embodiment, the upper surface of the thickened block 1 is connected with one end of the two traction belts 7, and the belt body of the traction belt 7 is distributed horizontally; the middle edge of the other end of the upper support plate 3a and the lower support plate 3b forms a concave contour with the end of the two adjacent support seats 4, and the middle edge of the other end of the lower support plate 3b forms a concave contour with the end of the two adjacent support seats 4 to completely expose the groin 9 puncture area, the concave contour of the upper support plate 3a and the upper connection area S1 of the end of the two adjacent support seats 4, and the concave contour of the lower support plate 3b and the lower connection area S2 of the end of the two adjacent support seats 4, S1>S2, to avoid affecting the full exposure of the puncture area during the femoral artery puncture operation.

[0033] In this embodiment, the upper surface of the upper support plate 3a is connected with the lower part of the connecting hose 5, and the upper part of the connecting hose 5 is connected with the outer surface of the sleeve 6. The connecting hose 5 is deformable, and the deformable connecting hose 5 is a qualitatively deformable connecting hose 5. The qualitatively deformable connecting hose 5 can flexibly and finely adjust the angle of the connecting hose 5 and the telescopic state, and at the same time has stability. The combined structure of the sleeve 6 and the connecting hose 5 can replace the operator to hold the needle for a long time, and can avoid unstable shaking or deviation of the needle causing puncture failure or bleeding.

[0034] In this embodiment, the sleeve 6 is arranged horizontally, and the sleeve 6 is a hollow annular body. The inner cavity contour of the sleeve 6 is consistent with the contour of the interventional needle handle. The inner cavity of the sleeve 6 and the outer surface of the needle handle of the interventional needle form an interference fit, so that the needle handle of the interventional needle can form a pre-tightening force in the sleeve 6, which can properly fix the needle handle. At the same time, the sleeve 6 increases the hand-holding area of ​​the interventional needle handle, so that the operator can hold the needle more stably.

[0035] In this embodiment, when the belt body of the traction belt 7 is in a taut state, the lower surface of the other end portion of the traction belt 7 is fixed to the skin surface of the upper end of the groin 9 by an adhesive connection, and the support plate undergoes elastic deformation. The other end of the upper support plate 3a bulges upward to form a convex arc surface, and the other end of the lower support plate 3b bulges downward to form a concave arc surface. After the support plate undergoes elastic deformation, according to Newton's third law, the thickening block 1 is subjected to a reaction force away from the groin 9 area, but due to the pulling effect of the traction belt 7 toward the groin 9, the thickening block 1 is also subjected to a traction force close to the groin 9, thereby offsetting the reaction force exerted on the thickening block due to the elastic deformation of the support plate, thereby maintaining the effect of the elastic deformation of the support plate.

[0036] In this embodiment, the support seat 4 of this device cooperates with the support plate 4, the upper support plate 3a, the lower support plate 3b, the thickening seat, the traction belt 7, and the adjustment belt 2 to enable the support seat 4 of the device to smoothly penetrate into the fold area of ​​the groin 9. At the same time, due to the elastic effect of the support plate, the skin at the fold of the groin 9 can be stretched. At the same time, the traction force of the traction belt 7 toward the groin 9 and the friction force generated by the fixing effect of the adjusting belt 2 on the thickening block 1 can offset the reaction force exerted on the thickening block 1 due to the elastic deformation of the support plate, thereby maintaining the effect of the elastic deformation of the support plate, and can replace the operator to stretch the skin in the groin 9 where the puncture area cannot be fully exposed due to fat accumulation, thereby reducing the burden on medical staff; the connecting hose 5 can flexibly and finely adjust the angle and telescopic length of the connecting hose 5, the sleeve 6 can properly fix the interventional needle handle, increase the hand-holding area and needle-holding stability of the interventional needle handle, and the combined structure of the sleeve 6 and the connecting hose 5 can replace the operator to maintain the hand-holding state for a long time, thereby avoiding unstable shaking or deviation of the needle holding resulting in puncture failure or bleeding.

[0037] In this embodiment, the middle edge of the other end of the upper support plate 3a and the lower support plate 3b forms an arc-shaped concave contour with the ends of the two adjacent support seats 4. The middle edge of the other end of the upper support plate 3a is connected with the upper end of the two adjacent support seats 4 to form an elliptical concave arc contour, and the middle edge of the other end of the lower support plate 3b is connected with the lower end of the two adjacent support seats 4 to form a circular concave arc contour.

[0038] In this embodiment, the cross-section of the other end of the support seat 4 is an arc-shaped profile, and the upper and lower parts of the arc-shaped profile are arranged tangent to the upper support plate 3a and the lower support plate 3b respectively. The arc-shaped profile of the other end of the support seat 4 can make the elastic deformation of the support plate fit more closely to the skin at the fold of the groin 9 when the upper support plate 3a and the lower support plate 3b stretch the fold area of ​​the groin 9, thereby increasing the stretching effect.

[0039] In this embodiment, the angle of the convex structure is R, and the range of R is 0°<R≤30°. An elastic opening is arranged laterally on the upper part of the sleeve 6, which makes the installation of the interventional needle handle more convenient. The inner cavity of the sleeve 6 is provided with multiple limiting bosses 6a, which further increase the friction between the outer surface of the interventional needle handle and the inner wall of the sleeve 6, thereby increasing the fixing effect of the needle handle and preventing the needle handle from slipping out of the sleeve 6. The outer surface of the sleeve 6 is provided with a thread line 6b, which increases the friction of the outer surface of the sleeve 6, thereby increasing the stability of the needle holding. The traction belt 7 is provided with an adhesive layer 8 on the lower surface of the end of the traction belt 7 to form a sticky connection with the skin.

[0040] The working process of this embodiment is as follows:

[0041] S1. Disinfect the puncture area of ​​the groin 9 and the device, place the support base 4, upper support plate 3a, lower support plate 3b, and thickening block 1 on the skin of the front thigh in the puncture area of ​​the groin 9, point the convex corner structure of the support base 4 toward the fold of the groin 9, and push the thickening block 1 toward the groin 9 so that the convex corner structure of the support base 4 penetrates into the fold area of ​​the groin 9.

[0042] S2. When the convex structure is against the groin 9, it continues to push the thickening plate toward the groin 9, causing the upper support plate 3a to elastically deform upward and the lower support plate 3b to elastically deform downward until the folds of the groin 9 are completely stretched.

[0043] S3. By adjusting the length of the belt 2, the leg skin below the thickening block 1 is fixed, the friction between the thickening block 1 and the skin is increased, and at the same time, the other end of the traction belt 7 is fixed on the skin surface above the groin 9, such as the abdominal surface skin, which can further offset the reaction force exerted on the thickening block 1 due to the elastic deformation of the support plate, thereby maintaining the effect of the elastic deformation of the support plate and maintaining the stretching effect.

[0044] S4. Install the interventional needle handle in the inner cavity of the sleeve 6 through the elastic outlet, and adjust the angle of the interventional needle handle installed in the inner cavity of the sleeve 6 and the depth of the needle insertion through the qualitatively deformable connecting hose 5.

[0045] S5. When it is determined that the needle tip of the interventional needle is inserted into the femoral artery, stop adjusting the qualitatively deformable connecting hose 5 so that the integral body formed by the qualitatively deformable connecting hose 5 and the sleeve 6 can maintain a stable state, and then send the catheter into the femoral artery, and then send the catheter into the heart along the femoral artery for subsequent heart treatment or examination.
