Description

An auxiliary device for end-to-side anastomosis of subclavian artery

technical field

The utility model belongs to the related technical field of medical equipment, in particular to an auxiliary device for end-to-side anastomosis of subclavian artery.

Background technique

Carotid-subclavian artery bypass surgery is an operation in which artificial blood vessels are anastomosed end-to-side with the common carotid artery and the subclavian artery respectively. This procedure is widely used in carotid artery stenosis, subclavian artery stenosis, and some aortic dissections and aortic aneurysms. The surgical steps are usually: (1) Make a transverse incision from the supraclavicular fossa to the medial border of the ipsilateral sternocleidomastoid muscle, free the subclavian artery and the ipsilateral carotid artery respectively; (2) Use two vessel-blocking forceps to block the Use scissors to incise the anterior wall of the subclavian artery longitudinally at the proximal end and distal end of the subclavian artery to be anastomosed; (3) take an artificial blood vessel of appropriate length and diameter and anastomose end-to-side with the incision on the anterior wall of the subclavian artery; (4) The end-to-side anastomosis of the artificial blood vessel and the ipsilateral carotid artery was performed in the same way. The position of the subclavian artery is deep, and it is very elastic and prone to deformation. During the process of direct end-to-side anastomosis, the anastomotic site of the subclavian artery often undergoes morphological changes such as folding, rotation, and movement, which brings great difficulties to the anastomosis. .

The end-to-side anastomosis of the artificial blood vessel and the left subclavian artery is the most critical step in carotid-subclavian artery bypass surgery. Since the subclavian artery is deep and easily deformed due to its good elasticity, in order to obtain a good anastomotic effect, the ideal situation should be that the chief surgeon and the assistant cooperate to use two blocking forceps to close the anastomotic part of the subclavian artery as much as possible. May be fixed. However, in actual operation, the distance between two independent blocking forceps and their respective heights are difficult to control, and the shape of the anastomotic site of the subclavian artery will undergo various uncontrollable changes. The experience and operating skills of the surgeon are considered. For inexperienced surgeons, due to the lack of auxiliary devices, it is difficult to perform end-to-side anastomosis of the subclavian artery with the current technology, which may affect the final surgical effect.

Therefore, we need a device to assist the surgeon to complete the end-to-side anastomosis of the subclavian artery, so as to obtain a satisfactory anastomosis effect as simply and quickly as possible.
