Background technique

Limb vascular trauma is a common trauma in wartime, and it is not uncommon in unexpected events such as traffic accidents and work injuries. functional impairment and other conditions, which seriously threaten the life and health of the wounded. This is because hemostasis, ligation and vascular anastomosis are the main methods for the treatment of vascular trauma at home and abroad. Among them, hemostasis, ligation, etc. are used in field rescue, and it is necessary to race against time. The purpose is to control bleeding and save lives. However, for the injury of some important blood vessels such as carotid artery, iliac artery and femoral artery, if ligation is given and vascular anastomosis cannot be performed in time to restore their blood supply, it will lead to serious consequences of amputation, cerebral infarction and even death.

Vascular anastomosis is the first choice for treatment after vascular injury, but it must have sufficient time, good anesthesia, perfect instruments, and advanced surgical techniques. Therefore, in wartime, vascular anastomosis can only be carried out by evacuating the wounded to the rear hospital far away from the battlefield. The evacuation of such wounded people takes time. Generally speaking, the tissue can tolerate ischemia time of 6-8 hours. If the ischemia time exceeds this time, even if the blood supply is restored, the recovery of limb function is not ideal, and even the drum still needs to be cut off. . The bypass tube is a device that temporarily connects the vascular wound to restore blood supply before vascular anastomosis. However, the existing bypass tube is used to inflate the balloon through a syringe or an inflation tube, which not only requires a syringe as an auxiliary device, but also is complicated to operate, which is not conducive to vascular trauma. Quickly stop bleeding and restore blood supply.
