Problems solved by technology

[0003] The current staplers are usually non-degradable staplers, which require the use of more precise and bulky staplers or supporting instruments. The staplers left in the body after surgery are not degradable, which will bring long-term foreign body sensation to the patient. If the degraded stapler stays in the body for a long time, it will form bulges, pits and spots on the blood vessel anastomosis, which will affect the blood flow velocity and bring long-term postoperative secondary injury risk and thrombosis risk to patients

Abstract

The invention provides a drug-loaded degradable blood vessel anastomat. The drug-loaded degradable blood vessel anastomat is characterized by comprising main components which are symmetrically arranged; each main component comprises a clamping part, a puncture part and a matching hole, and the puncture parts and the matching holes are symmetrically distributed in the clamping parts respectively; and the puncture parts of the adjacent main parts are connected with the corresponding matching holes in a matching manner. Through controllable degradation, the risk caused by retention of the vascular anastomat is reduced, the strength of the puncture parts can be guaranteed through a pointed iron core, the anastomosis effect is guaranteed, and meanwhile, an iron base body is degradable, the degradation component ferrous ions or iron ions are beneficial to formation of hemoglobin, and blood transportation is facilitated; and growth and differentiation of vascular cells can be promoted throughdrug loading, anastomosis of blood vessels at anastomotic positions is accelerated, generation of spots is reduced, and tissue damage is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drug-loaded degradable blood vessel stapler. Background technique [0002] In vascular surgery, the suturing of blood vessels is a necessary operation, usually including manual suturing and stapler anastomosis. Using manual suture usually takes more than 15 minutes, which not only increases the risk and cost of the operation for the patient, but also puts a greater burden on the doctor. At the same time, manual suture is based on the doctor's technique, physical strength and proficiency, and the suture quality is uneven. Postoperative recovery of patients brings certain risks, and severe complications may occur. Stapler is a device that replaces traditional manual suturing. It is reliable in quality, easy to use, especially fast in suturing, easy to operate and has few side effects. [0003] The current staplers are usually non-degradable staplers, which require the...
