Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a hemostatic device for vascular surgery. BACKGROUND

[0002] Vascular surgery is a branch of surgery, focusing on the prevention, diagnosis and treatment of peripheral vascular diseases other than cerebral and cardiac blood vessels. Limbs are the most frequently moving parts of the human body, and are more likely to be exposed to the external environment, so they are more susceptible to injury. Sharp injuries can directly cut or pierce blood vessels, leading to blood vessel rupture or rupture. Blunt injuries can damage blood vessels through bone fracture ends, extrusion or traction. Such injuries are very common in vascular surgery clinics and can lead to serious consequences such as limb ischemic necrosis, amputation and even death if not properly treated.

[0003] Hemostasis is a key step in the first aid of vascular trauma. The most commonly used hemostatic method in clinical practice is proximal compression, which works by pressing the blood vessel above the wound (proximal end) to block the blood flow source and achieve rapid hemostasis. When the blood vessel is compressed for hemostasis, the hemostatic effect is achieved by tourniquet binding or manual compression by medical staff. However, when using a tourniquet for hemostasis, the tourniquet needs to be loosened regularly to avoid limb ischemic necrosis. However, the degree of tourniquet loosening cannot be adjusted, and sudden complete loosening can cause blood flow to impact the wound, leading to rebleeding. When manually pressing for hemostasis, it is difficult to accurately control the pressure applied to the wound in real time, and it is impossible to ensure that the pressure is always within a safe and effective range. In addition, long-term manual compression can cause fatigue in medical staff, affecting the accuracy and consistency of the compression.

[0015] Compared with the prior art, the present application has the following beneficial effects: 1. This invention achieves precise pressure hemostasis of wound blood vessels through ingenious structural design. In use, after placing the injured limb of the patient on the support, a series of operations can fix and lower the arc-shaped pressure plate to press on the blood vessels above the wound. The arc-shaped pressure plate is designed to conform to the contour of the human limb, which can apply pressure evenly and stably, effectively blocking blood flow and achieving rapid hemostasis. This precise pressure method avoids the problems of uneven pressure and inaccurate pressure position that may exist in traditional hemostasis methods, greatly improves hemostasis efficiency, reduces the amount of bleeding of patients, and buys valuable time for subsequent treatment.

[0016] 2. In this invention, while the arc-shaped pressing plate moves down to press the blood vessel, the adjusting rod drives the synchronous pushing plate down, pushing the piston rod to slide inside the piston cylinder, squeezing gas into the inflatable airbag, causing it to inflate. The inflatable airbag and the arc-shaped pressing plate work together to press the blood vessel from different angles, further enhancing the hemostatic effect. This dual pressing mechanism can better adapt to different blood vessel shapes and positions, ensuring the comprehensiveness and reliability of hemostasis, and reducing the risk of rebleeding due to incomplete hemostasis.

[0017] 3. In this invention, the automatic movement of the arc-shaped pressure plate and the auxiliary pressure plate is achieved through the coordinated operation of components such as the servo motor, the synchronization rod, and the drive gear. During the hemostasis process, medical staff do not need to manually adjust the pressure continuously. The device can automatically complete the pressing and releasing actions according to the preset program. This not only reduces the workload of medical staff, but also improves the accuracy and consistency of operation, avoids operational errors caused by human factors, and allows medical staff to devote more energy to the overall treatment of patients.

[0018] 4. The present invention incorporates a pressure sensor and a controller. When the auxiliary pressure plate and hemostatic cotton come into contact with the patient's wound, the pressure sensor can detect the pressure signal in a timely manner and transmit the signal to the controller. The controller automatically starts or stops the servo motor according to the preset pressure range to ensure that the pressure applied to the wound is always within a safe and effective range. This intelligent control system can monitor and adjust the pressure in real time, avoiding secondary damage to blood vessels due to excessive pressure and ensuring the safety of the patient. Meanwhile, through the setting of the timer, when the auxiliary pressure plate and hemostatic cotton have been in contact with the patient's limb for a predetermined time, the timer will send a signal to the controller to restart the switching mechanism. The drive gear moves the adjusting rod down to press the blood vessel, while the push rod moves the auxiliary pressure plate and hemostatic cotton away from the wound. This timed switching mechanism avoids limb ischemia and necrosis caused by prolonged pressure. At the same time, when the arc-shaped pressure plate is removed, the pressure from the auxiliary pressure plate and hemostatic cotton can prevent the wound from bleeding again, providing a good environment for vascular recovery and promoting the patient's recovery process.

When the damping block 45 moves upward, the tension spring 46 at the bottom of the damping block 45 is stretched to store energy; After the arc-shaped pressing plate 33 presses the blood vessel, the bolt caps on the pushing rod 41 and the auxiliary rod 42 are removed, the two groups of second connecting plates 43 are respectively placed on the pushing rod 41 and the auxiliary rod 42, and then the bolt caps are screwed to fix the second connecting plates 43 and the auxiliary pressing plate 44; When the pushing block 27 pushes the damping block 45 to move to the limiting abutting plate 28, the clamping block 48 is squeezed to retract inwardly toward the damping block 45 under the action of the limiting abutting plate 28, so that the pushing block 27 can continue to move beyond the limiting abutting plate 28. When the pushing block 27 is separated from the clamping block 48, the return force of the reset spring between the clamping block 48 and the damping block 45 drives the clamping block 48 to reset and pop out; After the clamping block 48 resets and pops out, the clamping block 48 and the damping block 45 are no longer limited by the pushing block 27, and under the action of the return force of the tension spring 46, the damping block 45 drives the pushing rod 41 to slowly move downward; When the pushing rod 41 moves downward to the auxiliary pressing plate 44 and the hemostatic cotton 49 contacts the patient's wound, the pressure sensor on the auxiliary pressing plate 44 receives a pressure signal and transmits the signal to the controller. The controller starts the servo motor 23 to drive the synchronous rod 24 to rotate reversely, so that the driving gear 25 drives the two adjusting rods 31 to move reversely away from the patient's limb; When the driving gear 25 reversely rotates, the synchronous rack 26 reversely moves, and the synchronous rack 26 drives the pushing block 27 to move downward. At this time, the pushing block 27 is located above the clamping block 48. When the pushing block 27 moves downward, it contacts the inclined surface of the clamping block 48. The clamping block 48 retracts inwardly toward the damping block 45 under the pushing of the pushing block 27, so that the pushing block 27 moves beyond the clamping block 48. When the pushing block 27 moves beyond the clamping block 48, the clamping block 48 pops out again. At this time, the pushing block 27 is located below the clamping block 48; When the auxiliary pressing plate 44 and the hemostatic cotton 49 are in contact with the patient's limbs, the timer is started, and when the predetermined time is reached, the timer sends a signal to the controller to start the switching mechanism again, and the servo motor 23 rotates again to make the drive gear 25 drive the adjusting rod 31 to move downward to press the blood vessels, and the synchronous rack 26 moves upward again under the action of the drive gear 25, and drives the clamping block 48 and the damping sliding block 45 to move upward, and the pushing rod 41 drives the auxiliary pressing plate 44 and the hemostatic cotton 49 to move away from the wound, avoiding the two sides to press at the same time to cause secondary damage to the blood vessels.
