Abstract
The utility model discloses a marking ring of a coronary bypass proximal anastomosis stoma. The marking ring comprises a pair of semicircular titanium rings, wherein a left fixing ring and a right fixing ring are arranged at two ends of each semicircular titanium ring respectively, and the two semicircular titanium rings are spliced with each other and are bolted with each other through the left fixing ring and the right fixing ring of each semicircular titanium ring to form a complete circular ring. The technical measure adopted by the utility model is to make the marking operation of the proximal anastomosis stoma safer and more reliable, thereby avoiding damaging the aorta. The method has the advantages of simple operation, capability of calibrating the proximal anastomosis and effectively avoiding damage to the aorta.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, a coronary artery bypass operation near-end anastomotic stoma mark ring is related to particularly.
Background
The coronary artery bypass operation is an effective means for treating coronary heart disease, and in the operation, blood vessels at other parts of a patient are taken, one end of each blood vessel is anastomosed with the aorta, the other end of each blood vessel is anastomosed with the coronary artery at an ischemic part, blood flow is enabled to cross a narrow part and is re-delivered to ischemic myocardial tissue, and the part anastomosed with the aorta is called a proximal anastomosis opening.
When a patient needs to review radiography after an operation, a contrast catheter head needs to be plugged into a normal coronary artery opening under X-rays and a newly-built anastomotic stoma is used for injecting contrast agent to clarify the condition of a blood vessel, the position of the anastomotic stoma is high relative to the normal coronary artery opening, the specific position of each patient has large variation, a large amount of time and contrast agent are needed to search for the anastomotic stoma during the radiography, excessive rays can cause radiation damage to an organism, and the excessive contrast agent can damage the renal function. There are even many times when false conclusions about "bridge vessel occlusion" are made without finding anastomoses.
At present, some surgeons try to position an anastomotic stoma by using a method of making a steel wire into a circle in the operation or marking a circle around the anastomotic stoma by using a titanium clamp for hemostasis, so that time and labor are wasted, and the positioning effect is not reliable. The common steel wire ring is usually temporarily made of a steel wire for suturing the sternum, after the anastomotic stoma is finished, a circle of steel wire is firstly wound on the anastomotic stoma, and then the two ends of the steel wire are screwed together with force, so that the defect that the manufacture is time-consuming, the well-made anastomotic stoma can be damaged by mistake when the two ends of the steel wire are screwed together, and if the steel wire needs to be taken down in a secondary operation, the two ends of the wound steel wire are unscrewed with force, and blood vessels can be injured; the titanium clip for hemostasis is generally arranged around the aorta adventitia around the anastomotic stoma in a circle, and has the defects of time consuming, easy shedding and less obvious positioning than a complete ring.
SUMMERY OF THE UTILITY MODEL
The utility model provides an easy operation can implement to mark and can effectively avoid damaging the mark ring of the coronary artery bypass near-end anastomosis of aorta to the near-end anastomosis.
The utility model discloses a following technical scheme solves above-mentioned technical problem:
the utility model provides a mark ring of coronary artery bypass near-end anastomosis mouth, includes a pair of semicircle titanium ring, is equipped with solid fixed ring in a left side and the solid fixed ring in the right side respectively at the both ends of semicircle titanium ring, and two semicircle titanium rings splice each other and pass through solid fixed ring in a left side and the solid fixed ring in the right side of semicircle titanium ring bolt each other and form complete ring.
Compared with the prior art, the utility model has the advantages of as follows:
the technical measure adopted by the utility model is to make the marking operation of the proximal anastomosis stoma safer and more reliable, thereby avoiding damaging the aorta. The utility model discloses a pair of both ends have the semicircle titanium ring that the retaining ring detained, when implementing the mark to the near-end anastomotic stoma, only need to involute two semicircle titanium rings to locating at the near-end anastomotic stoma, make about on two semicircle titanium rings solid fixed ring coincide respectively and the suture is fixed, form a cover ring on the aorta and sew up on the adventitia of aorta with the slide wire through controlling solid fixed ring to make the ring steadily fix unmovable on the aorta adventitia. If the situation of the secondary thoracotomy occurs, the titanium ring can be taken down only by cutting the fixing suture short. After the technical measure of the middle fixing ring is adopted, the whole circular ring is fixed by four-point suture after being formed, is more stably connected to the aorta and is always kept unchanged at the position of the proximal anastomosis. Throughout the whole process, each step can be completed by adopting the special structure of the utility model, which is light, convenient, safe and reliable in operation, so as to ensure the safe and reliable operation of marking the proximal anastomosis stoma, for example: the two semicircular titanium rings are spliced into a circular ring and sleeved on the aorta, so that the operation of directly combining the circular ring on the aorta can be adopted, the steel wire needs to be bent around the aorta to form the circular ring on the aorta in the prior art, obviously, the operation of combining the semicircular titanium rings is much lighter than the operation of bending the steel wire and winding the steel wire on the aorta in the prior art, and the damage to the aorta is greatly reduced; the following steps are repeated: the connection of the two semicircular titanium rings of the utility model only needs to use a suture, while the two ends of the steel wire need to be wound together with force in the prior art; the utility model can be sutured on the adventitia of the aorta by using the slide wire commonly used in the operation to realize the accurate positioning and position keeping of the mark. Therefore, the utility model discloses a semicircle titanium ring and last solid fixed ring etc. technical measure of adopting can the simplified operation to make the operation safe and reliable more, can effectively avoid again damaging the aorta when accomplishing to implement the demarcation to the proximal end anastomotic stoma.
Compared with the prior art, the utility model discloses still have following beneficial effect: the two half titanium rings are sleeved on the anastomotic stoma after the anastomotic stoma is finished to be sutured and fixed, so that the blood flow of the anastomotic stoma is not influenced; the fixation is simple, only the sliding wire for routine bridging is used for suturing on the aorta adventitia, the fixation time of each anastomotic stoma can be finished within two minutes, and the operation progress is not influenced; the removal is convenient, and the titanium ring can be separated and taken down by cutting off the fixed suture line during the secondary operation; the development is clear, and the position of the anastomotic stoma can be clearly displayed by the titanium ring under the X-ray.
