Abstract
The utility model belongs to the technical field of medical equipment, and particularly relates to an intraoperative stent. For the intraopeartive stent used at present, the body temperature of a patient needs to be reduced to 18-20 DEG C, then the operation can be continued, the deep low temperature can injure the patient, and as the body temperature of the patient is extremely low, the recovering of the body temperature of the patient needs a long time, the extracorporeal circulation time is prolonged, and further the patient is injured. The intraoperative stent comprises an artificial vascular graft, a stent tube is arranged on the side wall of the artificial blood vessel extended by one end of the artificial vascular graft; and the length of the stent tube is 5-10cm, and the diameter of the stent tube is 8cm. In the utility model, the structure is simple, the body temperature of the patient does not need to be reduced to a deep low temperature state, not only are the functions of all visceral organs of the patient are protected, but also a clotting mechanism of the patient is protected from being injured, so that the survival rate of the patient is increased, and the postoperative complications are reduced.
Description
One, technical field:
This utility model belongs to technical field of medical instruments, especially relates to a kind of art medium-height trestle.
Two, background technology:
The art medium-height trestle that uses is that a metal rack outer wrapping artificial blood vessel constitutes at present, in operation process, behind the heart proximal part that coincide, patient's lower limb are stopping that the art medium-height trestle is installed under the situation of blood supply, then with aortic arch type vascular anastomosis, because of the time that coincide needs 45 minutes at least, just can carry out after patient's body temperature need being reduced to 18～20 ℃, deep hypothermia can cause the damage of patient's phrenic nerves, the destruction of thrombin, adding upper and lower extremities, to stop the blood supply time long, can cause the depletion of spinal cord injury and hepatic and renal function, again because patient's body temperature is very low, needing for a long time to have increased cardiopulmonary bypass time with patient's temperature recovery to normal condition, and then caused patient's damage, be to cause the many and high main cause of mortality rate of patient's post-operative complication, at present, this problem has become the many and high main cause of mortality rate of the full aortic arch replacement operation of puzzlement aneurysm of thoracic aorta patient post-operative complication.
Three, utility model content:
This utility model is in order to solve the weak point in the above-mentioned background technology; provide a kind of simple in structure; do not need patient temperature is reduced to the device of profound hypothermia state; both protected the function of each internal organs of patient; protected patient's clotting mechanism to avoid damage again; thereby improve patient's survival rate, reduce the art medium-height trestle of patient's post-operative complication.
For achieving the above object, the technical solution adopted in the utility model is: a kind of art medium-height trestle, comprise artificial blood vessel bracket, and it is characterized in that: a sidewall that prolongs the artificial blood vessel of described artificial blood vessel bracket is provided with support tube.
The length of described support tube is 5-10cm.
The diameter of described support tube is 8cm.
Compared with prior art, this utility model is simple in structure, does not need patient temperature is reduced to the device of profound hypothermia state; both protected the function of each internal organs of patient; protect patient's clotting mechanism to avoid damage again, thereby improved patient's survival rate, reduced patient's post-operative complication.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment:
A kind of art medium-height trestle comprises artificial blood vessel bracket 1, and a sidewall of described artificial blood vessel bracket 1 is provided with support tube 2; The length of described support tube 2 is 5-10cm, and the diameter of described support tube 2 is 8cm.
This utility model is a modified form art medium-height trestle; network structure is original art medium-height trestle; inwall is a metal grill; outer wall is wrapped in the artificial blood vessel; end at original art medium-height trestle has prolonged the 5cm artificial blood vessel; it is the support tube of 5-10cm for 8cm length that the 5cm artificial blood vessel's who prolongs sidewall is provided with diameter; after art medium-height trestle after will improveing is implanted to patient's descending aorta initial part; the tremulous pulse resistance is closed pincers the resistance of the artificial blood vessel between support tube and the original art medium-height trestle metal grill is closed; after draining the air in the art medium-height trestle only; connect an arterial cannulation at the support tube far-end patient's lower limb are carried out hemoperfusion; make the patient under the situation that does not need Deep Hypothermia Circulatory Arrest, finish the full aortic arch replacement operation of aneurysm of thoracic aorta, guarantee patient's life security.
