Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a vascular surgical hemostasis aid. Background Technology
[0002] Vascular surgery is a branch of surgery that focuses on the prevention, diagnosis, and treatment of peripheral vascular diseases, excluding cerebrovascular and cardiac vascular diseases. Since blood vessels are distributed throughout the human body except for hair, nails, and cornea, vascular surgery covers a wide range of applications. Hemostasis is achieved through the use of hemostatic aids in vascular surgery.
[0003] For example, Chinese Patent CN221654431U discloses a vascular surgical hemostasis aid. It includes a box body and straps fixedly mounted on both sides of the box body. The bottom of the box body has an opening, and a hemostatic plate is movably disposed inside the box body, penetrating the opening. Several stabilizing components are disposed between the hemostatic plate and the top of the box body, ensuring stable movement of the hemostatic plate. An adjusting component is disposed at the top of the hemostatic plate, penetrating the top of the box body, and drives the hemostatic plate to move. This utility model provides a vascular surgical hemostasis aid that frees the hands, facilitates hemostasis, allows control of pressure, and ensures stable movement of the hemostatic plate.
[0004] While the above examples demonstrate how applying pressure to blood vessels with a hemostatic plate can aid in hemostasis, in cold weather, the skin around the wound is directly exposed, resulting in a lower temperature. This, in turn, lowers the temperature of the blood in the wound vessels. Lower blood temperature inhibits platelet activity, slowing down platelet metabolism, including internal signal transduction pathways and enzymatic reactions. Reduced phospholipase activity affects the metabolism of platelet membrane phospholipids, which play a crucial role in platelet activation and coagulation. Therefore, a low temperature around the wound directly impacts the speed of hemostasis. Existing vascular surgical hemostatic aids lack heating capabilities, presenting certain inconveniences in their use. Utility Model Content
[0005] This invention provides a vascular surgical hemostasis aid to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A vascular surgical hemostasis aid includes a fixation mechanism, within which a vascular surgical hemostasis mechanism is disposed. The vascular surgical hemostasis mechanism includes a knob, a threaded post fixedly connected to the bottom of the knob, a threaded sleeve threadedly connected to the surface of the threaded post, a pressure sensor fixedly connected to the bottom of the threaded sleeve, a pressure plate fixedly connected to the bottom of the pressure sensor, a guide sleeve fixedly connected to the top of the pressure plate, a guide rod inserted into the inside of the guide sleeve, a heating block fixedly connected to the inside of the pressure plate, a replacement pad adhered to the bottom of the heating block, and a controller fixedly connected to the top of the pressure plate.
[0008] A further improvement of this utility model is that the controller is connected to the pressure sensor signal and the controller is connected to the heating block signal.
[0009] A further improvement of the present invention is that the fixing mechanism includes a fixing shell, and mounting parts are fixedly connected to both sides of the fixing shell, and a fixing strap is provided on the surface of the mounting parts.
[0010] A further improvement of this utility model is that: the surface of the fixing belt is provided with locking protrusions, and the other mounting component has a plug inserted inside.
[0011] A further improvement of this utility model is that: one end of the insertion rod is fixedly connected to a mounting plate, and the two ends of the mounting plate near the insertion rod are fixedly connected to springs.
[0012] A further improvement of this utility model is that one end of the spring is fixedly connected to the surface of the mounting component, and the other end of the insertion rod is fixedly connected to a locking plate.
[0013] A further improvement of this utility model is that: the surface of the locking plate overlaps with the surface of the locking protrusion, a display screen is fixedly connected to the surface of the fixed shell, and the display screen is signal-connected to the controller.
[0014] A further improvement of this utility model is that the surface of the threaded column is rotatably connected to the interior of the fixed shell, and the top of the guide rod is fixedly connected to the top of the inner cavity of the fixed shell.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] This invention provides a vascular surgical hemostasis aid. Through the design of the vascular surgical hemostasis mechanism, during hemostasis, a heating block can heat the area around the wound through a replacement pad, raising the temperature to 37-42 degrees Celsius. At this temperature, platelet activation can be accelerated to a certain extent. Within this temperature range, platelet energy metabolism is accelerated, and the concentration of calcium ions within the platelets increases. This is an important signal for platelet activation. The increased calcium ion concentration can promote the activation of glycoprotein receptors on the platelet membrane, thereby enhancing the binding capacity of platelets to fibrinogen, accelerating platelet aggregation, and thus speeding up hemostasis. Simultaneously, the pressure sensor can detect the pressure applied to the skin by the compression plate, preventing excessive or insufficient pressure and making it easier to use.

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to embodiments:
[0023] Example 1
[0024] like Figure 1-4As shown, this utility model provides a vascular surgical hemostasis aid, including a fixing mechanism. The fixing mechanism contains a vascular surgical hemostasis mechanism, which includes a knob 21. The bottom of the knob 21 is fixedly connected to a threaded post 22. The surface of the threaded post 22 is threadedly connected to a threaded sleeve 23. The bottom of the threaded sleeve 23 is fixedly connected to a pressure sensor 24. The bottom of the pressure sensor 24 is fixedly connected to a pressure plate 25. The top of the pressure plate 25 is fixedly connected to a guide sleeve 26. A guide rod 27 is inserted into the inside of the guide sleeve 26. The inside of the pressure plate 25 is fixedly connected to a heating block 28. The bottom of the heating block 28 is bonded with a replacement pad 29. The top of the pressure plate 25 is fixedly connected to a controller 210.
[0025] In this embodiment, by rotating the knob 21, the threaded post 22 rotates and pushes the threaded sleeve 23 downward, thereby causing the pressure plate 25 to move downward and compress the wound to be stopped. During the downward movement, the guide rod 27 slides along the guide sleeve 26 to guide the direction of the pressure plate 25. At the same time, during the rotation of the knob 21, the pressure sensor 24 detects the pressure applied to the threaded sleeve 23 and transmits it to the controller 210, which then displays it on the display screen 19 to accurately know the current pressure on the wound and avoid the pressure being too low or too high.
[0026] Example 2
[0027] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the controller 210 is signal-connected to the pressure sensor 24 and the heating block 28. The fixing mechanism includes a fixing shell 11, with mounting parts 12 fixedly connected to both sides of the fixing shell 11. The surface of the mounting part 12 is provided with a fixing band 13, and the surface of the fixing band 13 is provided with a locking protrusion 14. A rod 15 is inserted into the interior of another mounting part 12. One end of the rod 15 is fixedly connected to a mounting plate 16, and the two ends of the mounting plate 16 near the rod 15 are fixedly connected with springs 17.
[0028] In this embodiment, when a vascular surgeon is performing hemostasis on a wound on a limb, the limb to be hemostatically stopped is inserted into the fixation strap 13. Then, the mounting plate 16 is pulled outward to disengage the locking plate 18 from the locking protrusion 14. The position is adjusted so that the pressure plate 25 is positioned on the surface of the wound to be hemostatically stopped. Then, one end of the fixation strap 13 is pulled so that the fixation strap 13 contacts the skin and the pressure plate 25 contacts the wound surface. Then, the mounting plate 16 is released, and under the tension of the spring 17, the insertion rod 15 pushes the locking plate 18 to contact the surface of the locking protrusion 14, thus fixing the fixation strap 13.
[0029] Example 3
[0030] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, one end of the spring 17 is fixedly connected to the surface of the mounting part 12, the other end of the plug rod 15 is fixedly connected to the locking plate 18, the surface of the locking plate 18 overlaps with the surface of the locking protrusion 14, the surface of the fixed shell 11 is fixedly connected to the display screen 19, the display screen 19 is signal connected to the controller 210, the surface of the threaded column 22 is rotatably connected to the inside of the fixed shell 11, and the top of the guide rod 27 is fixedly connected to the top of the inner cavity of the fixed shell 11.
[0031] In this embodiment, the wound periphery is heated by the heating block 28 through the replacement pad 29, raising the temperature to 37-42 degrees Celsius. At this temperature, platelet activation can be accelerated to some extent. Within this temperature range, platelet energy metabolism is accelerated, and the internal calcium ion concentration increases. This is an important signal of platelet activation. The increased calcium ion concentration can promote the activation of glycoprotein receptors on the platelet membrane, thereby enhancing the binding ability of platelets to fibrinogen, accelerating platelet aggregation, and thus speeding up hemostasis, making it easier to use.
[0032] The working principle of this vascular surgical hemostasis aid will be explained in detail below.
[0033] like Figure 1-4As shown, when vascular surgeons are performing hemostasis on wounds of the limbs, the limb to be hemostatically stopped is inserted into the fixation strap 13. Then, the mounting plate 16 is pulled outwards to disengage the locking plate 18 from the locking protrusion 14. The position is adjusted so that the pressure plate 25 is positioned on the surface of the wound. One end of the fixation strap 13 is then pulled to bring it into contact with the skin, and the pressure plate 25 into contact with the wound surface. The mounting plate 16 is then released, and under the tension of the spring 17, the insertion rod 15 pushes the locking plate 18 into contact with the surface of the locking protrusion 14, thus fixing the fixation strap 13. Then, the knob 21 is rotated, causing the threaded post 22 to rotate and push the threaded sleeve 23 downwards, thereby causing the pressure plate 25 to move downwards and compress the wound to be hemostatically stopped. During this downward movement, the guide rod 27 slides along the guide sleeve 26, guiding the direction of the pressure plate 25. Simultaneously, the knob 21 rotates... During the turning of knob 21, the pressure sensor 24 detects the pressure applied to the threaded sleeve 23 and transmits it to the controller 210, where it is displayed on the screen 19 to accurately determine the current pressure on the wound and prevent the pressure from being too low or too high. Simultaneously, under the action of the heating block 28, the area around the wound is heated through the replacement pad 29 to a temperature of 37-42 degrees Celsius. At this temperature, platelet activation can be accelerated to a certain extent. Within this temperature range, platelet energy metabolism is accelerated, and the concentration of calcium ions inside the platelets increases. This is an important signal for platelet activation. The increased calcium ion concentration can promote the activation of glycoprotein receptors on the platelet membrane, thereby enhancing the binding ability of platelets to fibrinogen, accelerating platelet aggregation, and thus speeding up hemostasis and making it easier to use.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
