Problems solved by technology

Since the staples used in this stapler are directly exposed in the lumen after anastomosis, the advantages of bypass surgery over interventional therapy are lost to a certain extent.

Embodiment

[0027] Such as figure 1 As shown, the end-to-side stapler for coronary artery bypass grafting in this embodiment is an end-to-side stapler for small blood vessels, and includes an anastomotic part 1 , a stapler rod 2 and a stapler handle 3 from front to back. The outer diameter of the stapler rod 2 is 10mm, which is suitable for a 10mm clinical Trocar sleeve commonly used in clinical use.

[0028] The anastomotic part 1 includes two anastomotic arms 11, such as figure 2 and image 3 As shown, the external and internal structures of the two anastomotic arms 11 are mirror images, and the anastomotic arms 11 are roughly rectangular hollow structures. The two anastomotic arms 11 are arranged at the front end of the stapler rod 2 and have separate and closed states. When the two anastomotic arms 11 are in the separated state, the bridge blood vessels can enter between the two anastomotic arms 11; An anastomosis arm concave surface 16 is provided on the inner side, and an anasto...

Abstract

The invention provides a distal end side anastomat for a saphenous vein bypass graft for coronary artery bypass surgery. The distal end side anastomat is characterized in that the distal end side anastomat comprises an anastomosis part; the anastomosis part comprises two anastomosis arms which are arranged at the front end of an anastomat rod and have a separated state and a closed state; when the two anastomosis arms are in the separated state, the saphenous vein bypass graft can enter the position between the two anastomosis arms; when the two anastomosis arms are in the closed state, a passage capable of allowing the saphenous vein bypass graft to exist is formed between the two anastomosis arms; and the anastomat rod is provided with an anastomat handle which can control opening and closing of the anastomosis arms. The distal end side anastomat is not affected by the anastomosis sequence of anastomosis openings, saphenous vein bypass graft anastomosis operation under thoracoscope can be simplified, thus the technical difficulty of the bypass surgery under the complete thoracoscope is lowered, the surgery time is saved, and more surgery is minimally invasive to be beneficial for patients.

Description

technical field [0001] The invention relates to an end-to-side stapler for the distal end of coronary artery bypass grafting vessels, which belongs to the field of minimally invasive surgical instruments. Background technique [0002] Coronary artery bypass surgery is a surgery in which when the blood supply to the coronary artery is insufficient, blood is supplied from another blood vessel (graft) from the aorta (proximal) to the area of ​​the blood vessel distal to the blockage (distal). At present, in addition to traditional manual suturing, there are a series of special instruments for proximal anastomosis in coronary artery bypass surgery. The use of the stapler can simplify the operation and shorten the operation time. However, there are few staplers for the distal end of the graft vessel, and all of them have certain shortcomings. The main reason is that the coronary artery is attached to the heart wall and has branches into the myocardium, so that the degree of free...
