Limitation.
A kind of cardiovascular interventional therapy device provided by the embodiment of the utility model, including sting device, fixed device and
Hand-held device；As shown in Figure 1, in the utility model embodiment,
Sting device includes needle tubing 1, syringe needle 2, push rod 3, rubber stopper 4 and push handle 5, and the end seal of syringe needle 2 is plugged on needle
The front end of pipe 1, the Inner Front End of needle tubing 1 are provided with elastic sealing film 7, and rubber stopper 4 is provided in needle tubing 1, is connected on rubber stopper 4
There is push rod 3, the end of push rod 3 is connected with push handle 5, the through-hole 6 for being provided centrally with perforation of push rod 3 and rubber stopper 4, push handle 5
On offer be connected with through-hole 6 seal wire perforation 8；
Fixed device includes needle tubing support 9 and seat supports plate 10, and needle tubing support 9 opens wide for end, front end offers can
For the cylinder-like structure for the opening that syringe needle 2 is pierced by, the fixed front end for being set in needle tubing 1 of needle tubing support 9, seat supports plate 10 is three
It is a or four, seat supports plate 10 and needle tubing support 9 be connected and be uniformly arranged be arranged in needle tubing support 9 it is circumferential around；
Hand-held device includes Fixing shrink ring 11, hemispherical hand holder 12 and finger slotting ring 13, and Fixing shrink ring 11 is fixed
It is set in the rear end of 1 pipe shaft of needle tubing, Fixing shrink ring 11 and the end of needle tubing support 9 link together, and the setting of finger slotting ring 13 exists
