Description
Technical field
The present invention relates to surgery field of medical article technology, especially relate to a kind of Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement and preparation method thereof.
Background technology
Coronary artery bypass grafting is the conventional operation for the treatment of coronary artery disease.This operation is used vein or the arteries from taking off in chest, shank or arm, proximal anastomosis is at ascending aorta, far-end strides across the coronary artery of stenosis or occlusion, to improve the blood supply of heart and to reduce the probability that myocardial infarction occurs, thereby improves patients ' life quality and life-saving.Because Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth is an inclined-plane, directly be sutured on ascending aorta, the conventional postoperative situation that there will be the clot compression anastomosis mouth that anastomotic stoma is subsided and postoperative oozing of blood congeals into of bypass graft, cause bridge angiostenosis even inaccessible, do not reach the effect of improving myocardial blood flow, long-term postoperative patency rate also decreases, and serious also there will be thrombosis in proximal anastomosis mouth, jeopardizes patient's life.At present, not yet find clinically corresponding prevention method.
Summary of the invention
The deficiency existing for above-mentioned prior art, the object of this invention is to provide a kind of Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement, it has the situation that the anastomotic part blood vessel that can avoid occurring in coronary artery bypass grafting subsides or is extruded distortion, thereby reduces the feature of operation risk.Further, it has the situation that can prevent proximal anastomosis mouth obturation due to bridge blood vessel contracture, thereby improves the feature of long-term postoperative myocardial blood flow patency rate.Further, it has the advantages that to be easy to observation in vitro anastomotic stoma position.Finally, the present invention also provides the method for this bracing or strutting arrangement of preparation.
To achieve these goals, the technical solution adopted in the present invention is: Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement comprises arc body, the silk material braiding that body is prepared by Nitinol forms, the bottom of body has base, right side has port, base ovalize, port is rounded, and the low order end on base and port are provided with breach between bottom, wherein, the rounded diameter R of port is R=4mm, 5mm, 6mm, 7mm or 8mm, the major axis a of base institute ovalize is: a=13mm, and oval minor axis is identical with R; Described base and port are equipped with the bearing edge that heavy metal material is prepared from, and between bearing edge and silk material, wrap by medical nonabsorable stitching thread.
The external diameter of described silk material is 0.15mm, and is parallel to each other in unidirectional silk material, between the silk material of different directions, assumes diamond in shape, and meanwhile, the axle center distance B between adjacent filaments material is: D=2mm.
Described bearing edge cross section is rounded, and the external diameter of this circle is 0.3mm.
Described bearing edge is that titanium is prepared from.
The method of preparing Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement, comprises the following steps:
A), make body: the nitinol alloy wire material of cut-off footpath 0.15mm, by the dimensional requirement of body by netted silk material interlacing diamondwise, then through thermoforming process processing;
B), make the bearing edge of base and port: getting external diameter is the titanium silk of 0.3mm, the identical oval or circle of shape of circle forming shape and base and port;
C), bearing edge is wrapped to the base and port of body by medical nonabsorable stitching thread.
Described bearing edge is that silver is prepared from, and the purity of silver is not less than 99.9%.
The method of preparing Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement, comprises the following steps:
A), make body: the nitinol alloy wire material of cut-off footpath 0.15mm, by the dimensional requirement of body by netted silk material interlacing diamondwise, then through thermoforming process processing;
B), make the bearing edge of base and port: getting external diameter is that 0.3mm, purity are not less than 99.9% filamentary silver, the identical oval or circle of shape of circle forming shape and base and port;
C), bearing edge is wrapped to the base and port of body by medical nonabsorable stitching thread.
The advantage that the present invention has is: 1, in art, play the situation that the blood vessel of anastomotic stoma does not occur subsiding or is extruded distortion that supports.The two ends of Coronary Artery Bypass Grafting blood vessel proximal anastomosis mouth bracing or strutting arrangement body of the present invention are respectively equipped with oval-shaped base and circular port, port have different diameters (all sizes of the present invention except the distance of shaft centers of adjacent filaments material from, all the other are the external edge of parts along size).Like this, this bracing or strutting arrangement can be fixed on the inside of anastomotic stoma, plays the effect of supporting anastomotic stoma place blood vessel.After optimization, bracing or strutting arrangement forms by the silk material braiding with memory function, like this, even if this bracing or strutting arrangement is subject to external force and produces deformation, after external force removes, the bracing or strutting arrangement shape that can resile automatically in time, thus effectively prevent anastomotic part subsiding under external force.2, the postoperative anastomotic stoma obturation that delays, to keep the long-term patency of bridge blood vessel, improves long-term postoperative patency rate.The main cause of postoperative anastomotic part vascular occlusion is bridge blood vessel contracture and causing.Bracing or strutting arrangement of the present invention is taked the silk material braiding of the Nitinol with good shape memory function.This alloy is after thermoforming process is processed, and shape memory further strengthens.This bracing or strutting arrangement not only has certain intensity, can overcome angiospastic pressure, thereby avoids the obturation of anastomotic stoma; And toughness is fabulous, even if being subject to external pressure after being out of shape, still can recover at once original form in diminishing at the larger pressure in outside.Like this, effectively prevent the impact that bridge blood vessel contracture is brought.3, while check after operation in patients, be easy to accurately complete fast postoperative coronarography inspection.Base and the port of this bracing or strutting arrangement are provided with bearing edge, and this bearing edge is not less than 99.9% silvery by titanium or purity to be done, and bearing edge wraps on Yu Sicai by medical nonabsorable stitching thread.Like this, not only bearing edge fixation, and also titanium or silver material can stop that X ray passes through.Like this, be equivalent to, for this bracing or strutting arrangement provides detectivity labelling, can find accurately the position of anastomotic stoma according to this labelling.4, good air permeability, easy to use.The body of bracing or strutting arrangement adopts weaving manner to form, and has good breathability, there will not be the situation of bracing or strutting arrangement and blood vessel adhesion.And netted body is beneficial to passing through of the fixing wire rod of operation, and the size of bracing or strutting arrangement is accurate, and form science, can realize good cooperation with blood vessel, when use, and only need be by fixing by 2～3 pins, very convenient netted silk material.5, preparation technology is reasonable.The preparation technology of this bracing or strutting arrangement includes thermoforming step, and this step can strengthen the shape memory function of a material.6, adaptable.Body is provided with breach, and in the time of concrete use, the diameter of body has certain flexible surplus, makes bracing or strutting arrangement can adapt to the blood vessel individuality of relative broad range internal diameter like this.
