Description
Technical field
This utility model relates to the vascular surgery survival kit, is specifically related to a kind of temporary vascular shunt device, belongs to the 3rd type of embedded material.
Background technology
Temporary vascular shunt technology is an important emergency treatment technique in modern vascular surgery field, is specially adapted to the emergency action of Vascular injury in wartime and the pre hospital care of Vascular injury at ordinary times.Its treatment principle is; Through an artificial nest with the near-end of damaged blood vessels (comprising vein and tremulous pulse) and far-end UNICOM temporarily; Thereby guaranteed the blood perfusion that wounded's limbs are still remained valid under the situation of main vascular injury; Reduced warm ischemia time, for advantage has been created in follow-up definitiveness blood vessel prosthesis.War wound data over the years shows; Just because of the rational Application of vascular shunt art and other advanced damage control resuscitation technique, just make amputation rate after the extremity vascular wound in wartime from World War II 59.2% (the HUGHES CW.Arterial repair during the Korean war.Ann Surg.1958 in period; 147:555-561.) be reduced to 9.4% (the Kragh JJ of recent the war in Iraq; Walters TJ; Baer DG, et al.Survival with emergency tourniquet use to stop bleeding in major limb trauma.Ann Surg.2009; 249:1-7; Woodward EB, Clouse WD, Eliason JL, et al.Penetrating femoropopliteal injury during modern warfare:experience of the Balad Vascular Registry.J Vasc Surg.2008; 47:1259-1264,1264-126; Clouse WD, Rasmussen TE, Peck MA, et al.In-theater management of vascular injury:2 years of the Balad Vascular Registry.J Am Coll Surg.2007; 204:625-632; Sohn VY, Arthurs ZM, Herbert GS, et al.Demographics, treatment, and early outcomes in penetrating vascular combat trauma.Arch Surg.2008; 143:783-787; Peck MA; Clouse WD; Cox MW; Et al.The complete management of extremity vascular injury in a local population:a wartime report from the 332nd Expeditionary Medical Group/Air Force Theater Hospital, Balad Air Base, Iraq.J Vasc Surg.2007; 45:1197-1204,1204-1205; Clouse WD, Rasmussen TE, Perlstein J, et al.Upper extremity vascular injury:a current in-theater wartime report from Operation Iraqi Freedom.Ann Vasc Surg.2006; 20:429-434.).This technology has been applied to the Vascular injury wounded's early stage treatment (Fox CJ, Patel B, Clouse WD.Update on wartime vascular injury.Perspect Vasc Surg Endovasc Ther.2011 at present by U.S. army's routine; 23:13-25).
The temporary vascular shunt pipe that is applied to the U.S. army front at present is all slick plastic tube of inside and outside wall.Its main component be polyethylene or politef (Polytetrafluoroethylene, PTFE).The biologically inert that above-mentioned material is good has guaranteed that isocon is difficult for taking place hematoblastic adhesion after inserting blood vessel; Thereby guaranteed to implant good patency rate (the Clouse WD in back; Rasmussen TE; Peck MA, et al.In-theater management of vascular injury:2 years of the Balad Vascular Registry.J Am Coll Surg.2007; 204:625-632; Vertrees A; Fox CJ; Quan RW, et al.The use of prosthetic grafts in complex military vascular trauma:a limb salvage strategy for patients with severely limited autologous conduit.J Trauma.2009; 66:980-983.).But still there is deficiency in present isocon, after soon isocon inserts ends of vessels, also is to use traditional suture ligation that it is fixed (US2008046073A1) usually.This will cause following two problems:
One, because the outer wall and the tunica intima of isocon are all very smooth, simple suture ligation is not firm, might cause the end of isocon under the effect of blood flow continuous erosion power, to back away until deviating from fully.A research data according to U.S. army shows; The extrusion rate of isocon in the casualty evacuation process is 4.7% (Woodward EB; Clouse WD; Eliason JL, et al.Penetrating femoropopliteal injury during modern warfare:experience of the Balad Vascular Registry.J Vasc Surg.2008; 47:1259-1264,1264-1265.).Conceivablely be in the casualty evacuation process,, will be fatal to the wounded's threat in case isocon is deviate from.
Two, simplify operation technique to greatest extent, shorten operating time, rescue the wounded against time, be undoubtedly the target that the rescue personnel pursues for a long time.Particularly when a large amount of Vascular injury wounded occurring suddenly on the battlefield, it is particularly important that this point then seems.And the suture ligation also is a time-consuming relatively operation technique.Though each end of isocon only needs 2～3 knots to fix, tend to occur the situation that the arteriovenous of wounded's limbs is damaged simultaneously on the battlefield.At this moment, just to fixing isocon, just need make a call to high-quality suture knot more than 8～12.Only this item will cause huge technological challenge and psychological stress to the patient.Careless slightly, isocon just might tightly not get loose because of the suture ligation in the casualty evacuation process.
The utility model content
The purpose of this utility model is to provide a kind of novel temporary vascular shunt device, make the operation technique of fixing temporary vascular shunt pipe simpler and more direct, more rapidly, more firm, safer.
The temporary vascular shunt device of this utility model; The isocon that comprises inner wall smooth; It is characterized in that; This temporary vascular shunt device also comprises the hinge-type lock nut that is used for fixing the isocon end, and the isocon outer wall has external screw thread or annular projection, and the lock nut inwall has female thread or the annular recess that matches with it.
Further, that the material of said isocon is answered is nontoxic in the selective body, be difficult for degraded, be difficult for causing platelet aggregation and portable synthetic material, for example silica gel, polyethylene or politef; That the material of said lock nut is answered is nontoxic in the selective body, be difficult for the synthetic material of degraded, for example nylon, polyethylene or politef.Said isocon is preferably silica gel tube, polyethylene tube or polyfluortetraethylene pipe; The preferred nylon of said lock nut, polyethylene or politef hinge-type lock nut.
Usually, the external diameter scope of said isocon is 4～16mm, and when concrete the application, should be suitable with the blood vessel external diameter of accepting shunting.For example the external diameter in femoral artery stage casing be 6.00 ± 1.40mm (Pang Gang, Zhang Weilong. " human vas and vascular anastomosis clinical anatomy " Beijing: People's Health Publisher, 2010.), then the external diameter for the isocon in bridge joint femoral artery stage casing is 6mm.The isocon wall thickness is generally in 1～2mm scope.The isocon outer wall has external screw thread or annular projection.If be screw thread, then be preferably triangle thread, promptly the thread protrusion longitudinal section is triangular in shape, preferably is equilateral triangle.If be annular projection, then be preferably triangular hill, promptly the annular projection longitudinal section is triangular in shape, preferably is equilateral triangle.
Said lock nut is divided into two semicircle segmental arcs, and an end of two semicircle segmental arcs is articulated, and the other end is provided with the engaging piece that cooperatively interacts.
The temporary vascular shunt device of this utility model is made up of the isocon and the hinge-type lock nut of band external screw thread (or protruding) and inner wall smooth, and its fixing means is two ends nut lock methods.In use, select and the clip isocon, isocon is inserted damaged blood vessels, and lock the junction of isocon and damaged blood vessels with the hinge-type lock nut according to the diameter and the defect length of injured blood vessel.The temporary vascular shunt device of this utility model and existing application in the battlefield and the vascular shunt pipe of pre hospital care compare, can further simplify operation technique, shorten operating time, and effectively reduce the incidence rate that isocon is deviate from.
