Abstract
The present invention relates to a distal blood vessel vascular stapler for coronary artery bypass, which has the advantages of convenient and rapid operation, exact stapling effect, effective operation time reduction and operation risk reduction. The distal blood vessel vascular stapler comprises a stapling forceps and stapling nails, wherein the stapling forceps comprises a handle and a supporting rod connected with the handle; the ends of the supporting rod are respectively provided with a vein bypass end nail groove and a coronary end nail groove; a nail rack capable of sliding is arranged on the supporting rod provided with the coronary end nail groove; the nail rack is arranged between the vein bypass end nail groove and the coronary end nail groove; the stapling nails are fixed in the nail rack.
Description
One, technical field:
The present invention relates to a kind of medical apparatus and instruments, especially relate to coronary artery bypass distal vessels anastomat in the operation on heart.
Two, background technology:
At present, the coronary artery bypass distal vessels is coincide and is all adopted artificial needlework to sew up clinically, its length consuming time, and operating difficulties, and match result is imprecise, the situation of anastomotic leakage blood often occurs, causes operating time to prolong.
Three, summary of the invention:
The present invention provides a kind of coronary artery bypass distal vessels anastomat in order to solve the weak point in the above-mentioned background technology, and it is convenient to operation, and match result is definite, can effectively reduce operating time, reduces operation risk.
For achieving the above object, the technical solution used in the present invention is:
A kind of coronary artery bypass distal vessels anastomat, its special character is: comprise anastomosis forceps and anastomosis staple, anastomosis forceps comprises handle and the support bar that links to each other with handle, the support bar end is respectively Vein Bridge end nail groove and arteria coronaria end nail groove, have on the arteria coronaria end nail groove support bar and slidably follow closely frame, nail is set up between Vein Bridge end nail groove and the arteria coronaria end nail groove, and nail frame internal fixation has anastomosis staple.
Above-mentioned nail frame is connected with Vein Bridge end nail groove by gangbar.
Above-mentioned anastomosis staple is made with memory alloy material.
Above-mentioned anastomosis staple both sides have spike-tooth respectively.
Be provided with undercut and blade in the above-mentioned nail groove.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
The present invention adopts apparatus to replace artificial needlework to sew up, weak point consuming time, and match result is good, can fast and effeciently carry out far-end and coincide.
Four, description of drawings:
Fig. 1 is the structural representation of anastomosis forceps among the present invention.
Fig. 2 discharges preceding sectional drawing for anastomosis staple among the present invention.
Fig. 3 is the sectional drawing after anastomosis staple discharges among the present invention.
Fig. 4 is fixed in the interior sketch map of nail frame for anastomosis staple among the present invention.
Five, the specific embodiment:
Referring to Fig. 1, the present invention includes anastomosis forceps and anastomosis staple two parts, anastomosis forceps comprises handle 6 and the support bar that is connected as a single entity with handle, the support bar end is respectively Vein Bridge end nail groove 2 and arteria coronaria end nail groove 4, the support bar of arteria coronaria end nail groove 4 is provided with the nail frame 3 that can slide, nail frame 3 is connected with Vein Bridge end nail groove 2 by the gangbar 1 of support bar one side, is provided with the undercut of help spike-tooth bending and the blade of stripping and slicing blood vessel wall in the nail groove.Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, anastomosis staple is made with memory alloy material, and every piece of anastomosis staple is about 25mm, is fixed in the nail frame 10～14 pieces of anastomosis staples standby.There is the spike-tooth 5 of 1 or 2 1.5～2mm every piece of anastomosis staple both sides, coincide to protract laterally, and back spike-tooth 5 bendings that coincide are followed closely body refresh memory shape with the fix blood tube wall.
During real work, anastomosis staple and nail frame 3 are fixed on the anastomosis forceps, cut coronary artery, the arteria coronaria end nail groove 4 of anastomosis forceps is sent into coronary artery to far-end in carrying out ahead of schedule the coronary stricture far-end identical.Anastomosis forceps Vein Bridge end nail groove 2 is sent into the pre-vein that coincide from far-end.Hold anastomosis forceps handle 6 after adjusting anastomosis forceps and Vein Bridge position, two nails of anastomosis forceps groove is drawn close to the centre, extruding anastomosis staple, anastomosis staple spike-tooth 5 through crooked in undercut after the bilateral blood vessel wall, all are fixed in artery and vein vascular on the anastomosis staple simultaneously, simultaneously gangbar 1 is promoted downwards, nail frame 3 is opened, discharge anastomosis staple, anastomosis staple recovers shape owing to temperature raises, tunica intima is turned over laterally and the artery and vein vascular wall is fixed together, form and coincide.Withdraw from anastomosis forceps, with the venal distal ligation, the myometrial suture of arterial proximal.
