Vascular stapler and its operation method

Abstract

The invention discloses a blood vessel anastomat and an anastomosis operation method thereof. The blood vessel anastomat comprises a guide pipe sleeve assembly and a jaw assembly connected with the guide pipe sleeve assembly, wherein a discharging ring and an outer ring support pipe connected with the discharging ring are arranged in the jaw assembly, the outer ring support pipe is sleeved with an elastic blood vessel anastomat outer ring, and a blood vessel anastomat inner ring matched with the blood vessel anastomat outer ring is nested in the blood vessel anastomat outer ring. The anastomosis operation method comprises steps as follows: a blood vessel A is inserted and extends to the outer side of the blood vessel anastomat outer ring; a blood vessel B is nested outside the blood vessel anastomat inner ring and outwards turned; the blood vessel B is put in the blood vessel A; the blood vessel anastomat outer ring is pushed to be separated and clamped on the blood vessel B at the blood vessel anastomat inner ring. The blood vessel anastomat and the anastomosis operation method are convenient, reliable and stable to operate, thereby facilitating improvement of blood vessel anastomosis; by means of the improved structures of the blood vessel anastomat rings, the discharging ring and the outer ring support pipe, blood vessel fixation is more accurate during anastomosis, the conformability of the blood vessel is improved, and the success rate of the operation is higher.

Description

technical field [0001] The invention relates to blood vessel anastomosis technology, in particular to a blood vessel stapler and an anastomosis operation method thereof. Background technique [0002] Vascular anastomosis is the most commonly used and most important basic operation in surgery. Vascular anastomosis is required in many operations involving vascular diseases or war trauma, such as: vascular diseases, vascular transplantation, vascular repair and arteriovenous fistula production Wait. [0003] At present, there are two main methods of vascular anastomosis, one is suture anastomosis, and the other is anastomosis using vascular anastomosis instruments. So far, suture anastomosis is still the most basic and most commonly used vascular anastomosis in clinical practice. method. Even for a doctor with good surgical skills who has undergone long-term surgical training, it takes 5 to 30 minutes to manually anastomose each anastomosis. When more blood vessels need to b...

Problems solved by technology

Various types of vascular staplers have emerged one after another, and its common structure is a large vessel stapler disclosed in Chinese patent ZL 201310111076.7. It adopts a clamp body and a buckle fixing method. Although the structure is relatively simple, the accuracy of the operating position is low. , it is especially difficult to ensure the fit of the anastomotic blood vessels, and the accuracy of the anastomotic angle and position of the blood vessels cannot be guaranteed, and it is also difficult to disassemble after operation
