Self-locking type sewing-free buckle

Technical Field

The utility model belongs to the technical field of medical instrument's technique and specifically relates to a from locking-type buckle of exempting from to sew up.

Background

Aortic diseases, such as aortic aneurysm, especially aortic dissection aneurysm, have the characteristics of acute onset, fast disease progression, complicated disease condition and extremely high mortality. For the vast majority of patients with aortic aneurysms, including aortic dissection aneurysms, surgical treatment is required, with the use of artificial large vessels in place of the diseased arteries. Due to the fact that most diseased aorta tissues are seriously edematous and highly fragile, the operation of anastomosis of the artificial great vessel and the diseased aorta of a patient is very complex, the technical difficulty is high, an anastomosis opening is easy to bleed, and the anastomosis time is long, so that the Deep Hypothermia Circulatory Arrest (DHCA) time is prolonged, and serious complications such as ischemic brain injury or spinal cord injury are easy to occur. In recent years, cardiovascular surgeons have tried to perform aortic anastomosis using a non-suture method to reduce the anastomosis time and the probability of anastomotic bleeding, thereby reducing surgical complications and improving the surgical success rate of patients with aortic aneurysms.

The non-suture method, namely the non-suture artificial blood vessel intracavity transplantation method (SIG), takes the position of the autologous blood vessel of a patient, which needs to be anastomosed with the two ends of the artificial blood vessel, as the two cut ends of the autologous blood vessel of the patient, respectively puts the artificial blood vessel with fixing rings at the two ends into the two cut ends of the autologous blood vessel of the patient, and then ties the part corresponding to the fixing rings at the outer side of the autologous blood vessel to complete the fixation and anastomosis.

In the prior art, in SIG operation, a doctor often completes a blood vessel anastomosis process in a mode of knotting and fixing by using an umbilical cord on site, and the defects that the knotting and fixing force is uncontrollable, too fine silk thread force is easy to generate a cutting effect on autologous blood vessels of a patient, and the force is small, so that the autologous blood vessels of the patient can slip and leak blood to form a pseudo aneurysm exist; currently, as an improvement of the above-mentioned techniques, doctors have started to perform knot fixing using a string having a certain width. However, whether the silk thread or the silk ribbon is used, a plurality of circles of encircling are needed, the visual field and the operation direction of a doctor are perpendicular to the axis of the autologous blood vessel of a patient, the encircling distance of the silk thread or the silk ribbon can be the shortest, and the falling time of the silk thread or the silk ribbon is prolonged as much as possible. However, the aorta has an oblique posterior aortic arch after being sent out from the heart, the visual field and the operation space of the doctor for the aorta operation are quite limited, it is therefore very difficult to obtain the most advantageous position for tying during the operation, especially when ligature involving the aortic arch fracture, and, moreover, the threads and ribbons are flexible, the passing ratio is poor, the silk thread or silk ribbon is difficult to pass through in the circumferential direction of the anastomotic stoma position, the knotting of the two ends of the silk thread or silk ribbon is difficult after the silk thread or silk ribbon passes through, and after the knotting is finished, the position of the thread or ribbon is often not located on the circumferential surface of the vessel at the anastomotic site, but is not perpendicular to the vessel, namely, the knotted position of the silk thread or silk ribbon finally presents a skew state, the knotting is unstable and easy to slip and leak blood, and once the knot is made, the silk thread or silk ribbon can be tightly attached to the autologous blood vessel of the patient, so that the doctor is difficult to release and readjust.

That is, although doctors perform vascular anastomosis by knotting silk ribbon instead of silk ribbon in SIG operation, the effect of avoiding cutting effect is achieved, but at present, there are: the knotting position and strength are affected by the human factor of the operator to a great extent, which causes the difficult knotting operation to cause the long anastomosis time, the manual knotting is uncontrollable by the feeling and the force and the difference is large, the knotting is easy to slip to cause blood leakage, thereby forming the false aneurysm, and the knotting is difficult to readjust after finishing, and the like.
