Background technique

Endovascular dredging in patients is an effective method to relieve lower extremity ischemia. Usually, puncture from the patient's femoral artery is performed, and a guide wire is inserted from the disposition, and the stent or balloon is guided to the lesion site by the guide wire for delivery. Dilation of stenotic vessels, however, when the length of the lesion is long or the vessel cannot be adequately dredged from conventional femoral access, clinicians may resort to a retrograde approach, where puncture is performed "from far to near" from the distal end of the lesion For diseased blood vessels, the commonly used retrograde puncture arteries include the anterior tibial artery, the posterior tibial artery, and the distal end of the superficial femoral artery. The puncture points selected on the body surface are different. For the traditional approach, a variety of femoral artery compressions have occurred in clinical practice. Tourniquet.

The disadvantages lie in the following points:

1. The operation is cumbersome: the clinician needs to use gauze to cover the wound after the operation, and then use a medical bandage to wrap it around the puncture point repeatedly, which takes a long time.

2. Unable to observe the bleeding point: the puncture point is covered after the gauze and bandage are wrapped, and the clinician cannot observe the changes of the puncture point in time after the operation. 8 hours until the bandage was removed.

3. The tightness of the compression bandage is difficult to control: the clinician can only estimate the degree of compression by the feel of the hand and the depression of the patient's muscle and skin. If the compression is light, the compression and hemostasis effect cannot be achieved. Blood. If the pressure is found to be inappropriate, the bandage needs to be removed and recompressed.

4. Poor patient comfort: The combination of gauze and bandage is heavy, which will significantly increase the patient's discomfort when the weather is hot, and is prone to complications such as allergies and rashes. At the same time, the gauze and bandage used in this method are large in size, and their width may reach 20-30 cm. After bandaging, the patient feels a strong sense of restraint, and the limb movement will be limited to a certain extent.
