Abstract
Description
Technical Field
[0001] This invention relates to the field of hemostatic devices, specifically to a hemostatic device for general surgery. Background Technology
[0002] Hemostatic instruments used in general surgery are usually hemostatic forceps or gauze dressings. However, at present, general surgery uses hemostatic forceps to stop bleeding from large blood vessels in wounds and compression hemostasis methods for small blood vessels.

Forcibly clamping the wound end of the closed blood vessel can cause certain damage to the blood vessel itself.

[0043] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0044] The left clamp arm 11 and right clamp arm 12 are rotated by the pivot pin 14, and the jaws at the front ends of the left clamp arm 11 and right clamp arm 12 clamp the blood vessels inside the wound. Simultaneously, the locking rods between the left clamp arm 11 and right clamp arm 12 are used to lock them together. Then, the hemostatic gauze 31 is adhered to the front side of the end cap 21 through the Velcro patch 32. The combined upper hemostatic dressing assembly 2 and lower hemostatic dressing assembly 3 are then inserted laterally into the hemostatic forceps instrument 1 through the opening 33 and the insertion port 23. The arc-shaped outer shell 41... The bottom protrusion is coupled with the positioning groove on the protrusion 13. During the insertion process, the L-shaped insertion rod 44 will be inserted into the arc-shaped outer shell 41, and the elasticity of the semi-annular elastic plate 42 will allow the buckle 43 to be engaged in the inside of the slot 45. At this time, the hemostatic gauze 31 will contact the small blood vessel port inside the wound. Through the cooperation of the hemostatic forceps instrument 1 and the lower hemostatic dressing assembly 3, the posture of the hemostatic forceps instrument 1 clamping the large blood vessel is maintained, and the hemostatic gauze 31 stops bleeding at other bleeding points in the wound.
[0045] After the end cap 21 and hemostatic gauze 31 are placed on the wound, the release paper on the medical adhesive tape 24 is peeled off, and the medical adhesive tape 24 is allowed to adhere to the skin around the wound. The small servo pump 51 draws the coolant inside the low-temperature coil 22 into the drain pipe 52 through the return pipe 56. As the coolant passes through the return pipe 56 and the square hollow groove 57, the cooling end of the semiconductor cooling chip 55 cools the coolant. The heat from the semiconductor cooling chip 55 is released by the heat conduction plate 54 and the small fan 53. The cooled coolant will enter the low-temperature coil 22 along the drain pipe 52. Since the low-temperature coil 22 is embedded in the end cap 21, the coolant flowing inside the low-temperature coil 22 will cool the blood vessels around the wound, forcing the blood vessels to contract due to the cold and reducing the amount of bleeding.
