Abstract
The utility model provides a cardiovascular intervention therapeutic device, and belongs to the technical field of medical apparatus and instruments. The cardiovascular intervention therapeutic device is composed of a puncture needle head (1), a needle cylinder (2), a cylinder cover (3), a piston (4), a pintle (5), and a sealing plug (6). The cardiovascular intervention therapeutic device is characterized in that the outer wall at the back end of the needle cylinder (2) is connected with the cylinder cover (3) in a threaded mode, the front end of the needle cylinder (2) is connected with the puncture needle head (1), the front end of the pintle (5) with an axis hole penetrates through a through hole, and then is connected with the piston (4) inside the needle cylinder (2), the through hole is on the cylinder cover and is matched with the outer diameter of the cylinder cover, a cone-shaped elastic film (7) is arranged on the inner wall at the front end of the axis hole, the sealing plug (6) is arranged inside the back end of the axis hole, a gum cover (9) is arranged outside the puncture needle head (1), a gum plug (10) is arranged at the front end of the gum sleeve (9), an elastic clip (11) is arranged on the root portion of the gum plug (10), and a sealing film (8) is arranged on the end face of the through hole in the piston (4) in a direction close to the puncture needle head (1). Preferably, the thickness of the sealing film (8) is 0.5-2.0 millimeters, and preferably, the sealing film (8) is made of polytetrafluoroethylene.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of cardiovascular-interventional therapeutic equipment.
Background technology
When carrying out cardio-vascular interventional therapeutic, directly thrust blood vessel or thrust blood vessel with ordinary syringe with puncture needle at present, then syringe being unloaded from puncture needle, then seal wire is sent into blood vessel by piercing needle.The shortcoming of above-mentioned piercing method is: flow out a lot of blood from the needle holder mouth after puncture needle inserts blood vessel, wasted on the one hand valuable blood, also can pollute work surface on the other hand, may cause puncture needle Displacement damage blood vessel in wearing the process of seal wire, even cause puncture failure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can avoid blood to leak outside when the cardiovascular puncture for treating, and can be the cardiovascular-interventional therapeutic equipment of seal wire guiding.
On the one hand, this cardiovascular-interventional therapeutic equipment is comprised of piercing needle, syringe, cover, piston, pintle, sealing-plug, the back end of syringe outer wall thread that front end is connected with piercing needle is connecting cover, the pintle front end that is provided with axle center hole passes after the through hole that adapts with its external diameter above cover with piston in syringe and is connected, the axle center hole front inner wall is provided with the elastic film of circular cone tubular, and inside, rear end is provided with sealing-plug.
Preferably, in this cardiovascular-interventional therapeutic equipment, the through hole in piston is being provided with diaphragm seal near on the end face of piercing needle direction.
Preferably, the piercing needle needle body is provided with gum cover outward, and the gum cover front end is provided with plug, and the plug root is provided with elastic clip.
During use, hold syringe piercing needle is inserted blood vessel, then pull pintle, if there is blood to enter syringe, illustrate that syringe needle has inserted blood vessel, at this moment, insert seal wire in axle center hole and pass elastic film and can complete the conveying of seal wire by the piercing needle intravasation after opening sealing-plug above the pintle rear end.
Advantage of the present utility model: simple in structure, easy to use, piercing needle inserts and need not unload syringe after blood vessel and just can prevent the piercing needle displacement with seal wire along axle center hole and piercing needle intravasation reposefully, avoids flowing out a large amount of blood and pollutes work surface.

The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
In one embodiment, this cardiovascular-interventional therapeutic equipment is comprised of piercing needle 1, syringe 2, cover 3, piston 4, pintle 5, sealing-plug 6, the syringe 2 rear end outer wall threads that front end is connected with piercing needle 1 are connecting cover 3, be connected with piston 4 in syringe 2 after the through hole that pintle 5 front ends that are provided with axle center hole pass above cover 3 with its external diameter adapts, the axle center hole front inner wall is provided with the elastic film 7 of circular cone tubular, and inside, rear end is provided with sealing-plug 6.
In a preferred embodiment, as shown in fig. 1, in this cardiovascular-interventional therapeutic equipment, the through hole in piston 4 is being provided with diaphragm seal 8 near on the end face of piercing needle 1 direction.
In another preferred embodiment, as shown in Figure 2, be provided with gum cover 9 outside piercing needle 1, gum cover 9 front ends are provided with plug 10, and plug 10 roots are provided with elastic clip 11.When carrying out cardio-vascular interventional therapeutic to patient, piercing needle 1 thrusts blood vessel, and then fixing gum cover 9, extract piercing needle 1 out, and elastic clip 11 grips gum cover 9, inserts seal wires from plug 10 and gets final product.
In another preferred embodiment, the thickness of described diaphragm seal (8) is the 0.5-2.0 millimeter.
In another preferred embodiment, described diaphragm seal (8) is made by politef.
