Description
Technical field
The utility model relates to a kind of blood vessel anastomats, belong to the field of medical instrument technology.
Background technique
Currently, generalling use the side for disconnecting vascular suture for two when the blood vessel that doctor disconnects patient carries out anastomosis operation
Method is entered with the needle with line from the outer wall bundle of a disconnection blood vessel, and then needle enters another disconnection blood vessel from the inner cavity of this blood vessel
Inner cavity, prick outer wall from the inner wall of another blood vessel, the blood vessel that will be switched off several times repeatedly is coincide with line, however this
Operation but has following Railway Project, and since blood vessel is softer, several needles of beginning for being sutured with needle must be with instrument by blood vessel position
It sets and fixes, be convenient for contact pin, be usually to clamp externa with tweezers in existing situation, blood vessel is fixed, is clamped with tweezers
Blood vessel needs cannot destroy endangium, and since the head of tweezers is sharper, blood vessel is thinner, and tweezers are easy to arterial intima, shadow
Match result is rung, moreover, pricking vascular wall with needle in the case where no support has certain difficulty.
Utility model content
Technical problem to be solved by the utility model is: in order to overcome the problems referred above, providing one kind being capable of rapid suture, operation
Easy blood vessel anastomat.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of blood vessel anastomat, including branch pipe are provided with blood channel in the branch pipe, and the branch pipe includes the card at both ends
Enter portion and intermediate interconnecting piece, 12 suture troughs that annular is evenly spaced on is provided in the connection surface, wherein two
Gas-guide tube is provided between a suture trough, the gas-guide tube is connected to the blood channel in the branch pipe, is set on the gas-guide tube
It is equipped with air valve.
Preferably, the branch pipe is telescopic branch pipe.
Preferably, the snapin part at both ends and the junction of interconnecting piece are respectively arranged with card slot
Preferably, according to 12 moment of hour hands annular spread on the interconnecting piece, the gas-guide tube is arranged the suture trough
Between the 6th suture trough and the 7th suture trough.
Preferably, the end of the snapin part is arcwall face, tapered surface or trapezoidal faces.
Preferably, the air valve is the Non-return air valve by being connected in the blood channel of export-oriented branch pipe.
The beneficial effects of the utility model are: the utility model be provided with branch pipe be used for connect two be broken blood vessel it
Between, for protruding into the intravascular of fracture, blood is realized circulation out of blood channel, is provided in the connection surface for snapin part
12 suture troughs that annular is evenly spaced on carry out suture blood vessel using crochet hook, prop up first after branch pipe connects blood vessel
Pipe provides the power of a support, and crochet hook can cross needle out of suture trough, and will not destroy other organs and blood vessel, realize
Safe and convenient quickly sutures blood vessel, is very suitable to clinical use.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure chart of the utility model one embodiment.
Marked in the figure: 1- branch pipe, the snapin part 11-, 12- arcwall face, 13- interconnecting piece, 14- card slot, 2- suture trough, 3- air guide
Pipe, 4- air valve.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Embodiment 1
A kind of blood vessel anastomat described in the utility model as shown in Figure 1, including branch pipe 1 are provided with two in the branch pipe 1
The blood channel of perforation is held, has opening at the both ends of branch pipe respectively, the branch pipe 1 includes the snapin part 11 at both ends and the company of centre
Socket part 13, the branch pipe 1 are used to connect between the blood vessel of two fractures, and snapin part 11 is for protruding into the intravascular of fracture, blood
Circulation is realized out of blood channel, and 12 suture troughs 2 that annular is evenly spaced on are provided on 13 surface of interconnecting piece,
After branch pipe 1 connects blood vessel, suture blood vessel is carried out using crochet hook, branch pipe 1 first provides the power of a support, and crochet hook
Needle can be crossed out of suture trough 2, and will not destroy other organs and blood vessel, realized safe and convenient and quickly sutured blood vessel,
Be very suitable to clinical use, be provided with gas-guide tube 3 between two of them suture trough 2, the gas-guide tube 3 in the branch pipe 1
Blood channel is connected to, and air valve 4 is provided on the gas-guide tube 3, the gas-guide tube 3 is for being passed through nitrogen into branch pipe 1, at 12
2 use of suture trough has sutured 10 needles or so, and pouring nitrogen is fitted in blood vessel loosely no longer on branch pipe 1, then takes branch pipe 1
Out, then it is finally completed suture.
In a preferred embodiment, the branch pipe 1 is telescopic branch pipe 1, using the medical treatment of some flexible hardness
