Atrium cordis well generator

Abstract

The invention relates to the medical appliance field and aims at providing an atrium well generator for surgery. The atrium well generator consists of an upper ring and a low ring, which are sleeved on a movable rod. The lower ring is a semi-enclosed pressure ring (1) with one open end, the upper ring is a ring seat (3) matched with the pressure ring (1), and the movable rod is a tie rod which is sleeved in a hollow outer tube (4) and makes rectilinear movement; wherein the open end of the pressure ring (1) is fixed on the bottom of the tie rod (2), and the ring seat (3) is fixed on the bottom of the outer tube. The atrium well generator has the advantages that: the generator can simplify the generation of the atrium well under a minimally invasive condition without bleeding around an incision; the generator can meet the atrium well generation requirements under certain conditions with convenient use, safety, reliability, and reduced operational difficulty.

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.
