Abstract
Shaped surgical suture for intracorporeal knotting is shaped from an elastic surgical suture that is gelatine coated or thermally treated with shape memory to form two 3D open and unfastened loops (1) ended with C curve (2) whereas the first loop (1) is equipped with a surgical needle (3).
Description
Technical field
The present invention relates to the molding operation suture thread and its manufacture method of tiing a knot in body in sewing up for laparoscopy and thoracoscopy.The invention belongs to field of surgical.
Background technology
The various operation oversewing materials that current existence is distinguished according to stitching thread nature: braided suture and monofilament linea suturalis, Absorbable rod and nonabsorable stitching thread, also can distinguish according to different thickness.The main not damaged suture material used is provided with pin in its one end at present.The feature of surgical sewing needle is their size, bending, needle body and needle point cross sectional shape.In our research about existing apparatus, we also do not find in order in endoscopic surgery, having of tying object improves the stitching thread of shape.Such as, we know the nylon rope sling binding used in endoscopic surgery, and the binding of nylon rope sling can strain pre-prepd ring, and the braiding that this and we propose and the knotting method main distinction do not weave step for it.Also the known apparatus used in endoscopic surgery for weaving, it uses and is provided with long sutural not damaged suture material, and (body cavity namely carrying out wherein performing the operation is outer) knotting in vitro.Also have developed the mechanical apparatus for endoscope sewing: " the titanium knotting device (Titanium knot device for minimallyinvasive surgery) for Minimally Invasive Surgery " of LSI Solition, " the automatic peritoneoscope knotting of Nobel and stitching devices (Nobel AutomaticLaparoscopic Knotting and Suturing device) ", publish in October, 2010 in " Delhi health care and hospital's news (Health Care & Hospitals news) ", Delhi, India, or " the endoscope's knotting apparatus (Laparoscopic Knot-TyingDevice for Minimally Invasive Cardiac Surgery) for Cardiac operation with mini-trauma " (European cardiothoracic surgery periodical (Eur J Cardiothorac Surg.)) and other many articles.Our design is different, because it does not presuppose use sewing machine, and uses common endoscope surgical equipment.Another aspect comprises mechanical apparatus---and peg tissue by using nail and to get together organizing and cutting closer under the scope of mechanically closing tissue.But they can not replace stitching with operation without traumatic material completely.
In endoscopic surgery sew up and first knot correct making with avoid any undesirable unclamp still challenging with need the plenty of time.We can think that noinvasive suture material is by the eternal position in open operation and Minimally Invasive Surgery with it.
Because these are true, make great efforts in by when performing the operation relevant position apply a device unclamping knot form for opening to make as operation supplementary means to tie a knot in body during peritoneoscope and thoracoscopic operation stitching more easy.
Described effort impels and obtains invention described below, the invention solves the molding operation suture thread for tiing a knot in body and its manufacture method.
Summary of the invention
Above-mentioned shortcoming is eliminated according to the molding operation suture thread for tiing a knot in body of the present invention and its manufacture method.Key point for the molding operation suture thread of tiing a knot in body is: stitching thread is molded into by elastic surgical stitching thread to be had shape memory and forms two the 3D opening trip rings terminated with " C " shape curve, and wherein first ring is provided with surgical sewing needle.Operation suture thread or heat treated on specific device, or be coated with glue, to obtain its shape memory.This innovative idea may be used for manufacturing pre-prepared binode, and wherein two 3D opening trip rings turn clockwise, and arranged in series." C " shape part tying up to the curve on ring is left-handed, and its underpart curve terminates before the center of first ring.This innovative idea also may be used for making another pre-prepared binode, and wherein two 3D opening trip rings are rotated counterclockwise, and are arranged in series." C " shape part tying up to the curve on ring is dextrorotation, and its upper curve terminates before the center of first ring.This innovative idea also may be used for making another pre-prepared Slipped Clove Hitch, and wherein two 3D opening trip rings are arranged in parallel, and first ring is turned left, and the second hoop is turned right, and is that the lower curve of " C " shape part of curve thereon terminates before the second ring center.
Manufacture method for the molding operation suture thread of tiing a knot in body is: the elasticity of operation suture thread and shape memory are the results of operation suture thread heat treatment or operation suture thread rubber cover.The operation suture thread be around on the 3D device of opening trip ring and " C " shape curve with binode or Slipped Clove Hitch is heat-treated, and is exposed to temperature up to 90 ° one minute at the most.When covering glue, operation suture thread is coated with liquid glue, then around on the 3D device of the opening trip ring He " C " shape curve with binode or Slipped Clove Hitch, until gelling is solid.
Advantage according to the molding stitching thread for tiing a knot in body of the present invention and its manufacture method is: stitching thread has the pre-prepared 3D shape with ring, and such operating theater instruments is easy to accurately pass.After catching the sutural accurate directed end portion with the apparatus passed, after the traction making sutural both ends separated from one another subsequently, one accurately knot manufactured go out and fix.Like this, people save and make the time required for tying with endoscopic instrument.The predefined shape of stitching thread does not allow to adopt wrong step, and such as, the direction of ring is other direction.In this way, people can constantly tie a knot, and make applied knot have greater security.
The method that can obtain sutural shape memory is proposed, namely, the heat treatment of material and stitching thread glue cover, and seem that the performance for material does not impact.Stitching thread becomes flexible with regard to its 3D shape, but its intensity and longitudinal stretching length remain unchanged.
Accompanying drawing explanation
Molding operation suture thread for tying in body of the present invention is explained in the accompanying drawings further, and wherein, Fig. 1 shows to be had the pre-prepared of left-handed " C " shape curve and unclamp binode (double knot).Fig. 2 shows to be had the pre-prepared of dextrorotation " C " shape curve and unclamps binode.Fig. 3 shows and pre-preparedly unclamps Slipped Clove Hitch (slip knot).
