Abstract
The invention provides a proximal anastomosis device, and belongs to the technical field of surgical medical supplies. A lower part of a hemispherical body is provided with a circular bottom edge, the middle part of the hemispherical body is provided with a connecting shaft, the bottom edge of the hemispherical body is in circle shape, the diameter R of the circle is 16 mm, the hemispherical body is a hemisphere with a diameter A of 16 mm, the hemispherical body is formed by latticed body wires, and the latticed body wires are gathered and fixed at one point on the top end of the hemispherical body and connected with the connecting shaft. The proximal anastomosis device has the advantages that leakage from blood flow anastomosis stoma of aorta ascendens is prevented, a proximal end of saphenous vein bypass grafts is convenient to suture, and inner wall peeling of aorta ascendens caused by use of a side wall clamp is prevented. A memory function is provided by the proximal anastomosis device, so that after the proximal saphenous vein bypass graft is sutured in a surgery, the device can be taken out through catheters with diameters of 3.5 mm, 3.8 mm, 4.0 mm, 4.3 mm and 4.5 mm, and can be recovered to the original state for suturing the next proximal anastomosis stoma. The device can be reused in the same surgery of the same patient.
Description
Technical field
The present invention relates to a kind of proximal anastomosis device, belong to the surgery field of medical article technology.
Background technology
Coronary artery bypass grafting is the operation commonly used of treatment coronary artery disease.Vein or the arteries that takes off in chest, shank or the arm used in this operation; Proximal anastomosis is at ascending aorta; Far-end strides across the coronary artery of stenosis or occlusion, with blood supply that improves heart and the generation that reduces cardiovascular event, thereby improves patients ' life quality and life-saving.Because coronary artery bypass grafting bridge blood vessel proximal anastomosis mouth directly is sutured on the ascending aorta, when conventional BPG is sewed up the proximal anastomosis mouth, need to use the sidewall clamp to close the part ascending aorta; Blocking-up anastomotic stoma blood flow, and sew up near-end bridge blood vessel, but the sidewall clamp closes or when decontroling ascending aorta; Can cause ascending aorta inner membrance and atheromatous plaque to come off, blood vessel wall is impaired, causes body circulation thromboembolism easily; And then cause cerebral infarction, and distal artery blood vessel embolism, the particularly patient of ascending aorta calcification; Cause above-mentioned complication more easily, even cause the proximal anastomosis mouth to sew up.Do not find solution preferably at present clinically as yet.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide a kind of proximal anastomosis device, and it has and can avoid the use of the sidewall clamp and close ascending aorta, reduces the situation that calcification ascending aorta inwall peels off, thereby reduces the characteristics of operation risk.
To achieve these goals, the technical scheme that the present invention adopted is:
A kind of proximal anastomosis device, the bottom of hemispherical body has the base, the centre has connecting axle, and the base is rounded, and circular diameter R is 16mm; The hemispherical body is a hemispherical, and diameter A is 16mm; The hemispherical body is that latticed body silk material is formed, and body silk material comes together on the top of hemispherical body and is fixed in a bit, and is connected in connecting axle.
The advantage that the present invention had is:
1, plays the situation that stops ascending aorta blood flow self-fitting mouth seepage in the art; Make things convenient for suture bridges blood vessel near-end; Close without the sidewall clamp and just can accomplish coincideing of ascending aorta proximal anastomosis mouth, significantly reduced because of the ascending aorta folder close cause such as cerebral infarction, complication such as limb artery embolization.
2, this proximal anastomosis device forms through the silk material braiding with memory function; Like this; Can be the conduit taking-up of 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm through diameter with this device behind the stitching near-end bridge blood vessel in the art, and restore to the original state, be used for next proximal anastomosis mouth and sew up.
3, base loop buffer pad helps protecting the injury-free and anastomotic stoma sealing on every side of ascending aorta wall, prevents seepage.
4, for same patient, this device can be reused, and same operation of promptly same patient uses this device of cover can accomplish the stitching of all anastomotic stoma, reduced expense.
Device of the present invention takes to have the silk material braiding of the nitinol of good shape memory function.This alloy is after handling through thermoforming process, and shape memory further strengthens.Promptly this bracing or strutting arrangement not only has certain intensity, can overcome aortic pressure, thereby avoids the obturation of anastomotic stoma;
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the perspective view of the embodiment of the invention;
The schematic top plan view of Fig. 2 embodiment of the invention.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, like Fig. 1-shown in Figure 2, said proximal anastomosis device comprises hemispherical body 1; The bottom of hemispherical body 1 has base 4, the centre has connecting axle 2, and base 4 is rounded, and circular diameter R is R=16mm; Hemispherical body 1 is a hemispherical, and diameter A is A=16mm.
Said hemispherical body 1 forms through body silk material 3 braidings of nitinol preparation; The external diameter of body silk material 3 is 0.15mm, and is in unidirectional body silk material 3 and is parallel to each other, and assumes diamond in shape between the body silk material 3 of different directions; Simultaneously, being radial from the body top to the base scatters.
In hemispherical body 1 surface, liquid high resiliency thin film can use medical polyurethane, politef etc. with the high resiliency thin film coated of liquid state.
The thin film 5 that said hemispherical body 1 external application highly elastic material is processed, thin film 5 is with in the middle of the body silk material double team, and thin film 5 is airtight film, and blood is not penetrable, and thin film 5 thickness 0.2mm, base thin film 5 are annular, thin film ring diameter 0.3mm.
Said body silk material comes together on the top and is fixed in a bit, and is connected in connecting axle 2, and connecting axle 2 is one cylindrical, body diameter 1mm, and there is screw thread connecting axle 2 inside.
The thermoforming process of nitinol is handled and is belonged to prior art, repeats no more.
