Abstract
The utility model relates to a guide device for cardiovascular guide wire intervention for microinvasive surgical therapy. The guide device is characterized by comprising a needle syringe and a sealing ring; and a needle head seat is arranged at the front end of the needle syringe, wherein an inner hole of the needle head seat penetrates the entire needle syringe, and the sealing ring is arranged at an inner hole at the rear end of the needle syringe and aims to prevent the blood from leaking from the rear end of the guide device after the guide wire penetrates the needle syringe during the operating process. The guide device has the advantages of simple structure, convenient use and low cost. When the guide device is used, the guide wire is inserted into the front end of the guide device from the hole of the sealing ring at the rear end of the guide device for cardiovascular guide wire intervention, then the puncture needle is installed on the syringe needle seat at the front end of the guide device for cardiovascular guide wire intervention and inserted into the blood vessel, then the guide wire is pulled backwards, if the blood enters into the needle syringe, the needle head is inserted into the blood vessel, and the guide wire is pushed into the blood vessel forwards at the moment, so that the task of delivering the guide wire can be finished. The utility model has the benefits that no blood leaks during the operating process, and the guide wire can smoothly enter into the blood vessel.
Description
(1) technical field
This utility model relates to technical field of medical instruments, and a kind of specifically cardiovascular seal wire is got involved and used guide.
(2) background technology
At present, clinically when carrying out the cardiovascular interventional therapy to patient, the guide that seal wire is got involved usefulness replaces with disposable syringe mostly, exactly puncture needle is connected on the syringe, puncture needle is inserted blood vessel, again syringe is pulled up from puncture needle, seal wire is penetrated puncture needle send in the blood vessel.Like this, can flow out a large amount of blood in puncture needle when inserting seal wire, pollute work surface, shorter owing to the puncture needle exposed parts in the process of operation simultaneously, wayward its direction is so make the needle point displacement of puncture needle injure blood vessel easily.
(3) summary of the invention
This utility model provides a kind of and has prevented at puncture hourglass blood in order to overcome the defective of prior art, avoids the cardiovascular seal wire intervention guide of puncture needle displacement.
The technical scheme in the invention for solving the technical problem is as follows: this cardiovascular seal wire is got involved with guide and is made up of syringe and sealing ring.Wherein the syringe front end has a syringe needle to sit, and the endoporus that syringe needle is sat runs through whole syringe, and back end of syringe has a sealing ring, and its purposes is to guarantee in operating process, after seal wire penetrates, blood is leaked from the guide rear end.This is simple in structure, and is easy to use, with low cost.
During use, with seal wire from being inserted into the front end of guide in the cardiovascular seal wire is got involved sealing ring with the guide rear end, again puncture needle is contained in this cardiovascular seal wire intervention and takes and insert blood vessel with the syringe needle of guide front end, pull back seal wire, enter syringe if any blood, illustrate that syringe needle has inserted blood vessel, at this moment seal wire can be pushed ahead into blood vessel, can finish the task of delivery guidewire.
The beneficial effects of the utility model are: do not have blood leakage in operating process, owing to seal wire is inserted syringe in advance, so seal wire intravasation stably, whole affected process direction is difficult for change, has effectively overcome the defective that the traditional operation method makes the puncture needle displacement easily.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing, 1. syringe, 2. sealing ring.
(5) specific embodiment
The utility model will be further described below in conjunction with accompanying drawing: this cardiovascular seal wire is got involved with guide and is made up of syringe (1) and sealing ring (2).Wherein syringe (1) front end has a syringe needle to sit, and the endoporus that syringe needle is sat runs through whole syringe (2), and sealing ring (2) is contained in back end of syringe, and its purposes is to guarantee in operating process, blood is got involved with the guide rear end from the cardiovascular seal wire leaked.
Claims (1)
1. a cardiovascular seal wire that is used for Wicresoft's intervene operation is got involved and is used guide, it is characterized in that: this cardiovascular seal wire is got involved and is made up of syringe and sealing ring with guide, wherein the syringe front end has a syringe needle to sit, and the endoporus that syringe needle is sat runs through whole syringe, and there is a sealing ring at back end of syringe endoporus place.
