The application discloses a post-varicose vein surgery wound compression hemostasis device, which comprises a device main body for fixing on a limb, a pressure increasing module arranged on the device main body and an anti-reverse mechanism. The pressure increasing module comprises a rotating handle rotatably arranged on the device main body, a pressure push rod with a top end threadedly connected with the rotating handle and a compression pad arranged at the bottom end of the pressure push rod; the pressure push rod is slidably connected with the device main body. When the rotating handle is rotated clockwise, the pressure push rod is driven to move towards the skin side, so that the compression pad applies compression pressure on the wound. The anti-reverse mechanism is connected with the rotating handle and is used for preventing the rotating handle from being rotated counterclockwise, thereby preventing the compression pressure from being released accidentally. The device can accurately and stably maintain the compression pressure on the wound, avoids postoperative rebleeding or hematoma formation caused by pressure attenuation, and has the characteristics of convenient operation, safety and reliability.

This utility model provides a surgical delivery device for varicose vein closure surgery, belonging to the field of medical device technology. It includes: a main body shell, a push rod, a conduit, a positioning block, and a pressure block. The head opening of the main body shell is provided with a slot for mounting a syringe. The push rod pushes the piston rod of the syringe via a drive assembly. The conduit is provided with a guide groove for limiting the piston rod of the syringe. The push rod passes through a positioning hole on the positioning block and extends into the guide groove to contact the piston rod. The pressure block clamps the push rod. The syringe is fixed by the slot. When the drive assembly drives the push rod to push the piston rod, adhesive delivery is achieved. The precise cooperation of the positioning block, conduit, and slot improves the stability of the push rod and syringe cooperation, enhancing the continuity of the delivery device. The surgical delivery device for varicose vein closure surgery provided in this embodiment solves the problem of poor cooperation stability between the push rod and syringe in existing adhesive delivery devices.

This invention provides a medical adhesive closure system for varicose veins of the lower extremities, characterized by comprising an adhesive gun, a guidewire, a dilator, a guide sheath, a catheter, and a syringe. The adhesive gun consists of a handheld body and an adapter. The handheld body includes a spring-loaded trigger, a spike, a rack, a release button, a clamping block, and a locking block. Pressing the spring-loaded trigger allows for adhesive application, and the locking block holds the trigger in place to maintain pressure. During use, the guidewire is inserted into the body and passes through the lesion. The dilator is then inserted into the guide sheath and guided along the guidewire to the lesion. Once the guide sheath reaches the designated position, the dilator is removed and inserted into the catheter. The catheter is then connected to the adhesive gun for adhesive application. This invention utilizes adhesive treatment to close veins at room temperature, avoiding high temperatures and thermal damage. While addressing varicose vein complications, it improves the surgical experience and comfort, significantly increases treatment efficiency, and reduces medical costs.
