AI Technical Summary

Technical Problem

The existing vascular surgical hemostatic device has poor compression adjustment effect, which can easily lead to necrosis of the patient's leg tissue and inconvenient replacement of the hemostatic layer.

Method used

A vascular surgical hemostatic device including a hemostatic base, a conditioning mechanism and a hemostatic mechanism is designed. The adjustment mechanism can quickly change the support compression distance through the coordination of the threaded rod, the adjustment plate, the first spring and the adjustment nut; the hemostatic mechanism can achieve appropriate compression force and replaceable hemostatic tape through the coordination of the storage frame, the second spring, the compression piece, the connecting shaft, the roll and the hemostatic tape.

Benefits of technology

Through the design of the adjustment mechanism, the device can better adapt to the patient's limbs, improve the compression adjustment effect of hemostasis, and reduce the risk of tissue necrosis; the design of the hemostasis mechanism achieves convenient replacement of hemostasis patches and improves the efficiency of the device.

Abstract

The utility model relates to a vascular surgery hemostasis device which comprises a hemostasis base, an adjusting mechanism used for adjusting the supporting compression distance is arranged on the upper surface of the hemostasis base, and a hemostasis mechanism used for compression hemostasis is arranged on the adjusting mechanism. A placement groove is formed in the upper surface of the hemostasis base, the adjusting mechanism comprises two threaded rods, an adjusting plate, two first springs and two adjusting nuts, the two threaded rods are located on the left side and the right side of the placement groove respectively, two sliding holes are formed in the upper surface of the adjusting plate, and the adjusting plate is slidably connected to the outer sides of the two threaded rods through the two sliding holes respectively; the two threaded rods are movably sleeved with the two first springs respectively, the two ends of the first springs abut against the adjusting plate and the hemostasis base respectively, the two adjusting nuts are in threaded connection with the outer sides of the two threaded rods respectively, and the hemostasis mechanism is arranged on the adjusting plate and located above the containing groove. According to the hemostasis device for the vascular surgery, by arranging the adjusting mechanism, through mutual cooperation of a threaded rod, an adjusting plate, a first spring, an adjusting nut and the like, a limb can be placed in a placing groove to be matched with a buffer pad to be placed and positioned, and meanwhile during compression hemostasis, the limb can be conveniently placed and positioned; the connecting height can be changed by screwing the adjusting nut to rotate along the outer side of the threaded rod, the adjusting plate is pushed to abut against the adjusting nut by matching with the elastic force of the first spring, and the distance between the adjusting plate and the hemostasis base can be rapidly changed to adapt to the limbs of a patient for better hemostasis.
