Atrium cordis well generator

Abstract

The invention relates to the field of medical instruments and aims to provide an atrium well generator for surgical operations. It consists of two upper and lower rings set on the movable rod, the lower ring is a semi-closed pressure ring (1) with one end open, the upper ring is a ring seat (3) matching the pressure ring (1), and the movable rod is A pull rod (2) that is set in a hollow outer tube (4) for linear motion, wherein the open end of the pressure ring (1) is fixed on the bottom of the pull rod (2), and the ring seat (3) is fixed on the outer tube (4) bottom of. The advantage of the atrial well generator of the present invention is that it can simplify the generation of atrial wells under minimally invasive conditions, there is no bleeding around the incision, it is convenient, safe and reliable to use, it reduces the difficulty of surgery, and it can meet the needs of atrial wells in specific situations. .

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an atrium well generator for surgical operations. Background technique [0002] The atrial well is an open channel that connects the heart chamber with the outside world and contains blood on the wall of the atrium. Because there is a certain level of blood in it, the outside air cannot enter the heart cavity through this channel, thereby avoiding the occurrence of gas embolism. At the same time, because it connects the heart cavity and the outside world, certain operations in the heart can be carried out through this channel while the heart is beating, and the blood cannot overflow, thus avoiding heart stop and related complications. It is a useful technique that can be applied in surgery, especially the minimally invasive cardiac surgery that is currently advocated. In the 1950s, Dr. Gross of Boston Children's Hospital in the United States first applied this technology to c...

AI Technical Summary

Problems solved by technology

[0004] 1. The lower edge of the inverted conical rubber atrium well is directly sutured to the edge of the atrium incision, which cannot guarantee no blood leakage. At the same time, a large chest wall incision is required for easy operation, which does not meet the requirements of small incision and cosmetic surgery in modern surgery.

[0005] 2. The atrial incision at the bottom of the atrium well cannot be expanded automatically, which affects the entry and exit of operating instruments. A retractor or a special spreader must be used to expand the atrial incision, which makes the operation difficult and also makes the operation with small incisions difficult. hard to accomplish

[0006] 3. Long production time

[0007] In view of the above reasons, the previous atrial well technology can not be well applied in modern minimally invasive cardiac surgery, and some technical improvements are needed before it can be applied to atrial septal defect repair surgery with small incisions and off-pump conditions

But at present, there is no special instrument or device for generating atrial wells on a beating heart at home and abroad.
