Abstract

The utility model relates to a vascular anastomosis instrument. The utility model adopts a core rod with diminishing top of one end which is provided with falling; a plurality of needles are arranged outside of the core rod; the needle heads hide in the falling part; the needle tails are fixed with a propulsion panel which can move along the core rod; the outside lateral of the needles and core rod is sheathed with a bushing, and the inside lateral is provided with a plurality of needle grooves which share the same quantity with the needles and has the same distance with each other. All sutures can be accomplished for one time. The instrument can be used for suturing the blood vessels in manners of end to end, end to side, and side to side and is suitable for blood vessel, ureter, spermaduct and salpinx, in particular for the operations of organ transplantations. The utility model has the advantages of simple structure, simple-to-use, normative suture, good effect, simplified procedures, short time and therefore lowering of the pain of the patients.

Description

Blood vessel anastomat

This utility model relates to a kind of blood vessel anastomat, belongs to medical surgical instrument.

Before this utility model is made, mostly adopt directly in the operation and sew up, comprise tremulous pulse to tremulous pulse, tremulous pulse is to vein, form has end-end to coincide, and end to side coincide, side-side-to-side anastomosis, and embedding inosculating, all be to clamp two anastomotic stoma with vascular clamp, draw close laggard breaking joint in the ranks and close.Because blood vessel both sides fracture end is in free state, the fracture end has tension force again, and obliteration, vessel lumen is little, and inserting needle goes out relatively difficulty of pin, and needle gage, the back gauge of adding sewing up blood vessel also have certain requirement, therefore the clinician is had relatively high expectations, even the doctor that operation skill is good also can be unstable owing to psychology, mood tiredly makes an uproar, fatigue, factor such as be short of physical strength, and can't guarantee that each the stitching all not have to slip up.In addition, the inventor has also noticed the vascular suture method or the apparatus of practical application in some operations, as vascular anastomosis wheel method, blood vessel need be turned up, and very easily injured blood vessel wall and tube chamber can narrow down, so range of application is subjected to very big restriction; Next resembles laser weld and binding agent is bonding, clearly uses and is subjected to very big restriction; Other blood vessel anastomat and for example, technical step is many and complicated, needs also not to be used widely with multiple or apparatus repeatedly.

The purpose of this utility model just is to overcome above-mentioned defective, design a kind of simple in structure, the blood vessel anastomat of the also simple and standard of operation.

The technical solution of the utility model: blood vessel anastomat, plug one end top is gradually little, and major technique is provided with pin around being characterised in that the plug outside, and plug, the pin outside are socketed with sleeve pipe, and the other end of pin is connected with pushing plate, and pushing plate is actively socketed on plug one end.

Advantage of the present utility model and effect are simple in structure, simple to operate, and step is simplified, sewing effect standard, unification, and operating time is short, reduces patient's misery.

Embodiment 1:

As shown in Figure 1: an end top of plug 1 diminishes gradually, is good to be taper shape or circular arc, and depression 9 is arranged at the diameter rear portion of taper shape or circular arc-shaped bottom portion, is the depression 9 that radian is arranged; Be socketed with pushing plate 2 on the other end of plug 1, pushing plate 2 can move forward and backward along plug 1, fixed the backshank of many pins 3 on the pushing plate 2, pin 3 can take off forward from pushing plate 2, be installed with line 4 on the pin 3, these pins 3 are equidistantly arranged along plug 1 lateral direction, syringe needle 5 is concealed depression 9 places at the taper shape of an end of plug 1 or circular arc rear portion, the outside at plug 1 and pin 3 is socketed with sleeve pipe 6, identical and the equidistant needle tray 7 of a plurality of numbers with pin 3 is arranged on the inboard of sleeve pipe 6, pin 3 can move in needle tray 7, and sleeve pipe 6 can be taken apart, close.

As Fig. 1, shown in Figure 2: when needs carry out the end of blood vessel 8-end when sewing up, the end top that taper shape or circular arc are arranged of plug 1 is inserted into a little part the blood vessel 8 from the fracture end of blood vessel 8, blood vessel 8 fracture end both sides are strutted a little, because the syringe needle 5 of pin 3 is concealed at depression 9 places, so inwall place that syringe needle 5 is also just held with 8 fractures of plug 1 intravasation, enforce pushing plate 2, pin 3 marches forward in the needle tray 7 of sleeve pipe 6 inboards along plug 1, syringe needle 5 is along the radian at plug 1 depression 9 places, pass outwards through blood vessel 8 from blood vessel 8 inwalls, syringe needle 5 just is in outside the blood vessel 8, spur syringe needle 5 then, the backshank of pin 3 breaks away from pushing plate 2 and takes off, and the line 4 on the backshank of pin 3 passes blood vessel 8, open sleeve pipe 6, withdraw from plug 1 and get final product; For another blood vessel 8 that needs are sewed up, also be to carry out (shared single line 4) as method, with line 4 knottings of two blood vessels, 8 fracture ends, stitching just is through with then.Because it is equidistant that the spacing of pushing plate 2, plug 1,6 pairs of many pins 3 of sleeve pipe is carried out, add syringe needle 5 pass blood vessel 8 etc. back gauge, make local regulation, unification, the standard of sewing up, and many pins 3 advance side by side, speed is fast, the efficient height.

Embodiment 2:

As shown in Figure 3: when needs carry out the end to side stitching of blood vessel 8, plug 1 adopts semicircle shape or semicircle arcuation, it is roughly the same when other structure and end-end is sewed up, the blood vessel 8 lateral circular holes of so-called side are divided into two semicircles processing, earlier the semicircle of plug 1 or the groove 10 of semicircular arc are aimed at a semicircle that needs stitching, promote pushing plate 2 forward, syringe needle 5 outwards passes blood vessel 8 in blood vessel 8, pulling syringe needle 5 to line 4 passes blood vessel 8, and then carry out another semicircle of blood vessel 8 equally, with line 4 knottings of blood vessel 8 of wired 4 what is called ends identical with embodiment 1, promptly finished the stitching of end to side blood vessel 8.

Close for vessel side-latasuture, similar with the foregoing description.

Adopt this utility model, can carry out the stitching of blood vessel, ureter, bile duct, deferent duct and fallopian tube etc., especially in the operation of organ transplantation, exhibit one's skill to the full especially.
