Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a fixed puncture clip for cardiovascular patients. Background Art

[0002] In the field of the treatment of cardiovascular diseases, the puncture operation is an extremely crucial and widely used diagnosis and treatment technology, and its importance is self-evident. Whether it is to extract body cavity secretions for laboratory tests, inject gas or contrast agents for angiography, or accurately inject drugs into the body cavity, the puncture method is indispensable. However, there are many problems to be solved urgently in the actual application of existing puncture auxiliary devices.

[0003] On the one hand, the individual differences of patients are extremely large, with different body types, blood vessel positions, and anatomical structures of the puncture sites. Taking central venous puncture as an example, the positions and depths of the subclavian veins of different patients vary significantly. However, many current puncture clamping devices lack effective adjustment functions and are difficult to adapt to these differences. This results in that in actual operation, the puncture needle often cannot accurately reach the target position, which not only increases the difficulty and time of puncture, but also may cause additional harm to patients, such as blood vessel injury, surrounding tissue injury, etc., affecting the diagnosis and treatment effect and prolonging the patient's recovery period.

[0004] On the other hand, there are also serious deficiencies in the hemostasis link after puncture. Traditional hemostasis methods often have poor effects and cannot be flexibly adjusted according to the specific conditions of patients. During the operation or after trauma, the amount of bleeding is difficult to be effectively controlled, which may cause serious complications such as hemorrhagic shock, posing a great threat to the life safety of patients. Especially for cardiovascular patients, their physical conditions are usually relatively fragile and their tolerance to bleeding is worse, and the risks brought by such poor hemostasis effects are more prominent.

[0005] In addition, the current puncture auxiliary devices also have defects in terms of operation convenience and adaptability. During the use process, medical staff need to spend extra energy to adjust the devices to meet the needs of different patients, which not only increases the complexity of the operation, but also may delay precious treatment time in case of emergency.

[0006] In summary, the existing puncture techniques have obvious deficiencies in key links such as clamping adjustment and hemostasis, and are difficult to meet the needs of the diagnosis and treatment of cardiovascular diseases. There is an urgent need for an innovative fixed puncture clip for cardiovascular patients to improve the current situation and enhance the puncture accuracy, safety, and diagnosis and treatment efficiency. Summary of the Invention

[0007] In order to solve the many drawbacks that occur during the current puncture process. If the puncture clamping device cannot be adjusted according to different patients, since the body shapes, blood vessel positions, and anatomical structures of the puncture sites of each patient vary. If the puncture clamping device cannot be adjusted, it is difficult to adapt to the individual differences of different patients, which may cause the puncture needle to fail to accurately reach the target position. For example, in central venous puncture, the positions and depths of the subclavian veins of different patients are different, and a fixed clamping device may not meet the needs of different patients. Moreover, the current hemostatic effect is also not good, which will further lead to an increase in intraoperative or post-traumatic bleeding volume, possibly triggering hemorrhagic shock and seriously endangering the patient's life. The purpose of the present invention is to provide a fixed puncture clip for cardiovascular patients to solve the problems raised in the above background technology.

The material of the first soft protective layer is polyurethane foam. A second soft protective layer is fixedly connected to the side of the second clamping hoop. The material of the second soft protective layer is soft silicone foam. Polyurethane foam is a commonly used soft protective material with good softness, elasticity, and air permeability. The polyurethane foam can fit the skin surface to form a protective layer to prevent the intrusion of external bacteria and pollutants. The soft silicone foam dressing is mainly made of silicone material.

[0010] As a preferred solution of the present invention, a bearing is installed on the top of the supporting plate, and the connecting rod extends into the bearing.

[0011] As a preferred embodiment of the present invention, a second soft protective layer is fixedly connected to the side surface of the second clamp, and the material of the second soft protective layer is soft silicone foam.

[0012] As a preferred embodiment of the present invention, an integrated box is fixedly connected to the top of the connecting rod, a third telescopic rod is installed on the top of the integrated box, and a puncture needle is fixedly connected to the output end of the third telescopic rod.

[0013] As a preferred embodiment of the present invention, both the first telescopic rod and the second telescopic rod are electric telescopic rods and are respectively electrically connected to an external control device. The telescopic lengths of the first telescopic rod and the second telescopic rod can be independently controlled through the external control device.

[0014] As a preferred embodiment of the present invention, the third telescopic rod is a self-locking telescopic rod. After adjusting to an appropriate puncture depth, it can lock the position to prevent accidental movement of the puncture needle during the puncture process.

[0015] As a preferred embodiment of the present invention, the hemostatic sheet is a detachable structure and is connected to the pressing block by means of Velcro or snap connection, which is convenient for replacing different types or used hemostatic sheets.

[0016] As a preferred embodiment of the present invention, an anti-slip pad is provided at the bottom of the support plate, and the material of the anti-slip pad is rubber, which increases the friction with the placement plane and prevents the entire device from sliding during the puncture operation.

[0017] As a preferred embodiment of the present invention, scale marks are provided on the top frame, and the scale marks correspond to the length direction of the sliding groove, which is used to intuitively display the position of the second clamp in the sliding groove and facilitate medical staff to accurately adjust the clamping distance.

[0018] As a preferred embodiment of the present invention, the motor is a stepper motor, and the rotation angle of the motor can be accurately set through an external control device, so as to more accurately control the angle adjustment of the puncture needle.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. Precise adjustment of clamping to improve puncture accuracy and stability: Through the ingenious design of the first telescopic rod and the chute in the fixed puncture clip of this patent, the second clamp can be flexibly controlled to slide in the chute, enabling the second clamp to approach or move away from the first clamp according to the patient's body type, thus achieving precise clamping of the puncture site. This design solves the problem that traditional clamping devices cannot adapt to individual differences among patients and greatly enhances the stability of the puncture process. In actual operation, the puncture site characteristics of different patients vary, and the adjustable clamping device can closely fit the patient's body contour, effectively reducing the risk of displacement or slippage of the puncture needle during puncture and significantly improving the accuracy of the puncture needle reaching the target position. Taking central venous puncture as an example, medical staff can accurately adjust the clamping device according to the specific position and depth of the patient's subclavian vein to ensure that the puncture needle accurately enters the target blood vessel, avoiding the pain and harm caused to the patient by repeated punctures.

[0020] 2. Flexible adjustment of hemostasis to ensure patient safety: The hemostasis pressing component is a major highlight of this patent. With the telescopic function of the second telescopic rod, the pressing block and the hemostatic sheet can be precisely controlled to press down, and the pressing force can be flexibly adjusted according to actual needs. This feature is of great significance in clinical applications. The blood vessel conditions and physical conditions of different patients vary, and the positions, sizes, and depths of the wounds are also different. The adjustable hemostasis device can provide personalized hemostasis solutions for each patient according to these differences. In case of bleeding, medical staff can adjust the pressing force in a timely manner according to the severity of the bleeding to achieve effective hemostasis, greatly reducing the risk of hemorrhagic shock caused by increased bleeding during the operation or after trauma and effectively ensuring the patient's life safety.

[0021] 3. Multi-angle adjustment of the puncture needle to adapt to complex anatomical structures: The design of the puncture adjustment component enables the puncture needle to have a multi-angle adjustment function. The motor drives the connecting rod to rotate, which in turn drives the integrated box and the third telescopic rod and the puncture needle connected to it to adjust the angle. This design allows the puncture needle to be flexibly adjusted according to the specific anatomical structure of the puncture site to ensure that the puncture needle can accurately reach the target position. Whether facing patients with special blood vessel positions or complex puncture sites, medical staff can quickly adjust the angle and depth of the puncture needle through simple operations. Moreover, this adjustable puncture needle design is easy to operate and does not require medical staff to have complex operating skills, improving the puncture efficiency while reducing the risks caused by improper operations and providing more reliable technical support for the diagnosis and treatment of cardiovascular diseases.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment, please refer to Figures 1 - 4 The present invention provides a technical solution: A fixed puncture clip for cardiovascular patients, including a main body 1, a hemostasis pressing assembly 2 is arranged on the top of the main body 1, and a puncture adjusting assembly 3 is fixedly connected to the top of the main body 1.

[0026] In this embodiment, as Figure 1 、 Figure 2 and Figure 3As shown, the main body 1 includes a bottom plate 101. A top frame 102 is fixedly connected to the top of the bottom plate 101. A chute 108 is formed inside the top frame 102. A first telescopic rod 105 is installed inside the chute 108. A first clamp 103 is fixedly connected to the top of the top frame 102. The output end of the first telescopic rod 105 is fixedly connected to a second clamp 104. The second clamp 104 slides inside the chute 108. The hemostatic pressing assembly 2 includes an adapter block 201. A second telescopic rod 202 is installed on the top of the adapter block 201. The output end of the second telescopic rod 202 is fixedly connected to a pressing block 203. A hemostatic sheet 204 is fixedly connected to the side of the pressing block 203. The puncture adjustment assembly 3 includes a support plate 301. There are two support plates 301. An installation seat 303 is arranged on the top of the support plate 301. A motor 304 is installed on the side of the installation seat 303. The output end of the motor 304 is fixedly connected to a connecting rod 305. By the expansion and contraction of the first telescopic rod 105, the second clamp 104 can be controlled to slide inside the chute 108, so that the second clamp 104 approaches the first clamp 103, thereby clamping the puncture part of the patient, achieving the purpose of length adjustment according to the patient's body type. While enhancing the stability, it also improves the accuracy of the puncture needle 308. The adjustable clamping device can ensure that the puncture needle 308 remains stable during the puncture process, reducing the risk of displacement or slippage.

[0027] Among them, a first soft protective layer 106 is fixedly connected to the side of the first clamp 103. The material of the first soft protective layer 106 is polyurethane foam. A second soft protective layer 107 is fixedly connected to the side of the second clamp 104. The material of the second soft protective layer 107 is soft silicone foam. Polyurethane foam is a commonly used soft protective material with good softness, elasticity and air permeability. Polyurethane foam can fit the skin surface to form a protective layer to prevent the intrusion of external bacteria and pollutants. The soft silicone foam dressing is mainly made of silicone material. By the expansion and contraction of the second telescopic rod 202, the pressing block 203 and the hemostatic sheet 204 are controlled to press down, which can not only accurately press and stop bleeding at the puncture site, but also adjust the pressing force according to needs for effective hemostasis. The hemostatic device with adjustable pressing force can be adjusted according to the specific position, size and depth of the wound. The vascular conditions and physical conditions of different patients vary. The adjustable hemostatic mechanism can stop bleeding in time according to the specific situation of the patient.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, a bearing 302 is installed on the top of the supporting plate 301. The connecting rod 305 extends into the interior of the bearing 302. The top of the connecting rod 305 is fixedly connected to an integrated box 306. A third telescopic rod 307 is installed on the top of the integrated box 306. The output end of the third telescopic rod 307 is fixedly connected to a puncture needle 308. By driving the connecting rod 305 to rotate using the motor 304, the inclination angle of the third telescopic rod 307 and the puncture needle 308 on the side of the integrated box 306 can be adjusted, thus realizing the function of adjustable angle of the puncture needle 308. It can be adjusted according to the specific anatomical structure of the puncture site to ensure that the puncture needle 308 can accurately reach the target position. The design of the adjustable puncture needle 308 usually has a simple and easy-to-use operation mechanism, and medical staff can quickly adjust the angle and depth of the puncture needle 308 without complex operation skills.

[0029] In the present invention, the first telescopic rod 105 and the second telescopic rod 202 are both electric telescopic rods and are respectively electrically connected to an external control device. The first telescopic rod 105 and the second telescopic rod 202 adopt an outer shell made of high-strength aluminum alloy material, which has the characteristics of light weight and high strength. It can reduce the weight of the entire device while ensuring the structural stability of the telescopic rod, facilitating the operation of medical staff.

[0030] An advanced ball screw drive mechanism is adopted inside the electric telescopic rod. This drive mechanism has the advantages of high transmission efficiency and high positioning accuracy. The pitch of the screw is precisely designed to ensure that the telescopic rod moves smoothly during the telescopic process without jamming or shaking.

[0031] The external control device adopts a microprocessor control technology and is equipped with a liquid crystal display screen and operation buttons. Medical staff can input the required telescopic length value through the operation buttons. After receiving the instruction, the microprocessor will precisely control the motor rotation of the first telescopic rod 105 and the second telescopic rod 202, thereby realizing the independent control of the telescopic length of the telescopic rod. At the same time, the liquid crystal display screen will display the current telescopic length of the telescopic rod in real time, facilitating medical staff to monitor and adjust.

[0032] In the present invention, the third telescopic rod 307 is a self-locking telescopic rod. When adjusted to the appropriate puncture depth, it can lock the position to prevent accidental movement of the puncture needle 308 during the puncture process. The self-locking structure of the third telescopic rod 307 adopts a ratchet and pawl design. Inside the telescopic rod, the ratchet is fixedly connected coaxially with the screw rod, and the pawl is connected to the outer shell of the telescopic rod through a spring.

[0033] When the medical staff adjusts the third telescopic rod 307 to the appropriate puncture depth, the pawl will engage with the ratchet under the action of the spring, thereby realizing the self-locking of the telescopic rod. This self-locking structure has the advantages of large self-locking force and high reliability, and can effectively prevent the puncture needle 308 from accidentally moving due to external forces during the puncture process.

[0034] To facilitate the operation of the medical staff, an unlocking button is provided on the outside of the third telescopic rod 307. When the puncture depth needs to be adjusted again, press the unlocking button, and the pawl will separate from the ratchet against the elastic force of the spring. At this time, the telescopic length of the third telescopic rod 307 can be freely adjusted.

[0035] In the present invention, the hemostatic sheet 204 is a detachable structure and is connected to the pressing block 203 by means of Velcro or snap connection, which is convenient for replacing different types or used hemostatic sheets 204. If the Velcro connection method is adopted, mutually matching Velcro rough surfaces and hook surfaces are provided on the back of the hemostatic sheet 204 and the bottom of the pressing block 203. This connection method has the advantages of firm connection and convenient disassembly. The medical staff only needs to gently tear it to complete the replacement of the hemostatic sheet 204.

[0036] If the snap connection method is adopted, a snap groove is provided at the bottom of the pressing block 203, and a snap protrusion matching the snap groove is provided at the edge of the hemostatic sheet 204. When installing the hemostatic sheet 204, just align the snap protrusion with the snap groove and gently press, and the snap protrusion will be stuck in the snap groove to realize the connection between the hemostatic sheet 204 and the pressing block 203. When disassembling, just pull the hemostatic sheet 204 out of the pressing block 203 forcefully.

[0037] In the present invention, an anti-slip pad is provided at the bottom of the support plate 301. The material of the anti-slip pad is rubber, which increases the friction with the placement plane and prevents the entire device from sliding during the puncture operation. The anti-slip pad is made of nitrile rubber, which has good wear resistance, oil resistance and anti-slip performance.

[0038] The surface of the anti-slip pad is designed with a unique pattern, and the pattern adopts a combination of wavy and dot-shaped designs. The wavy pattern can increase the contact area between the anti-slip pad and the placement plane, thereby increasing the friction; the dot pattern can form tiny air channels between the anti-slip pad and the placement plane to prevent the anti-slip pad from being difficult to move due to the adsorption effect.

[0039] The anti-slip pad is firmly pasted to the bottom of the support plate 301 by strong glue to ensure that the anti-slip pad will not fall off during use. At the same time, to facilitate the replacement of the anti-slip pad, a lifting belt is provided at the edge of the anti-slip pad, and the medical staff can easily tear the anti-slip pad off the bottom of the support plate 301 through the lifting belt.

[0040] Scale markings on the top frame 102 In the present invention, scale markings are provided on the top frame 102. The scale markings correspond to the length direction of the sliding groove 108, and are used to visually display the position of the second clamp 104 in the sliding groove 108, facilitating medical staff to accurately adjust the clamping distance. The scale markings are made by laser engraving technology, with clear scales, wear-resistant and not easy to fade.

[0041] The accuracy of the scale markings is at the millimeter level, which can meet the accurate adjustment requirements of medical staff for the clamping distance. A pointer is provided on the second clamp 104. The pointer corresponds to the scale markings. When the second clamp 104 slides in the sliding groove 108, the pointer will move along with the second clamp 104. Medical staff can accurately read the position of the second clamp 104 in the sliding groove 108 through the scale markings pointed by the pointer.

[0042] In order to facilitate medical staff to read the scales under different lighting conditions, the scale markings are filled with luminous materials and can be clearly visible in a dark environment.

[0043] In the present invention, the motor 304 is a stepper motor, and the rotation angle of the motor 304 can be accurately set by an external control device, so as to more precisely control the angle adjustment of the puncture needle 308. The stepper motor adopts a permanent magnet stepper motor, which has the advantages of large torque, high precision and fast response speed.

[0044] The drive circuit of the motor 304 adopts microstepping drive technology, which can further subdivide the step angle of the motor, thereby improving the rotation accuracy of the motor. The external control device adopts computer control technology. Medical staff can input the required rotation angle value through computer software. After receiving the instruction, the computer will transmit the instruction to the drive circuit of the motor 304, and the drive circuit will accurately control the rotation angle of the motor 304 according to the instruction.

[0045] In order to ensure the accurate rotation angle of the motor 304, an encoder is provided on the output shaft of the motor 304. The encoder can monitor the rotation angle of the motor 304 in real time and feedback the monitoring data to the external control device. The external control device will adjust the rotation angle of the motor 304 in real time according to the feedback data, so as to achieve precise adjustment of the angle of the puncture needle 308.

[0046] Workflow of the present invention: When a fixed puncture clip for cardiovascular patients designed by this solution is in operation, the part to be punctured is placed between the first clamp 103 and the second clamp 104. The telescopic movement of the first telescopic rod 105 can control the sliding of the second clamp 104 inside the chute 108, and then make the first telescopic rod 105 approach the first clamp 103, so as to clamp the puncture part of the patient, achieving the purpose of length adjustment according to the patient's body type. The inner walls of the first clamp 103 and the second clamp 104 are provided with soft protective layers to protect the patient's skin. During puncture, the driving of the motor 304 drives the connecting rod 305 to rotate, so as to adjust the inclination angles of the third telescopic rod 307 and the puncture needle 308 on the side of the integrated box 306, thus realizing the function of adjustable angle of the puncture needle 308. After the position is determined, the third telescopic rod 307 can be used to control the puncture needle 308 to puncture the patient. During the hemostasis process, the pressing block 203 can adjust the hemostasis pressing force as needed through the telescopic movement of the second telescopic rod 202.
