Description
Technical field
This utility model relates to a kind of arteria coronaria card punch, belongs to cardiac operation technique with the apparatus field.
Background technology
In the coronary artery bypass grafting, need punch at ascending aorta, the bridge blood vessel that coincide, arteria coronaria card punch are the indispensable device of ascending aorta punching; The arteria coronaria card punch of clinical use now is disposable product (to same operation of same patient) that promptly a card punch just can not reuse to make a call to a hole only; And the card punch of this type punching effect is relatively poor, and it is not thorough to punch, and the tissue adhesion is many; Often occur because the patient of the situation, particularly calcific aortic that tear in the hole that tissue adhesion's pulling causes causes aorta damaged easily; Cause oozing of blood, serious causes because of the damaged massive hemorrhage of ascending aorta, the situation of death.
Summary of the invention
In order to solve the technological deficiency of arteria coronaria card punch existence now, the purpose of this utility model provides a kind of arteria coronaria card punch that is used for cardiac operation.
To achieve these goals, the technical scheme of this utility model employing is:
A kind of arteria coronaria card punch, the card punch body front part links to each other with sleeve pipe, and sleeve pipe is connected with the rear end rotating shaft; The fixing yellow jacket cushion rubber of the terminal groove of rotating shaft, rotating shaft outer casing spring circle, turn two ends extension; Be fixedly connected respectively at rotating shaft two ends corresponding aperture, external fixation is in the turn both sides respectively for shell A, shell B, and the disk card of rotating shaft afterbody is assigned in shell A, shell B cooperates in the circular groove of forming; The key of screwing connects rotating shaft, and the key of screwing connects shell A and shell B simultaneously.
Card punch main body, tip are an inverted cone stainless pin, closely are connected with main body.The rotating shaft front end links to each other with sleeve pipe, and the cover external diameter of pipe is divided into and is 3.5mm, 3.8mm, 4.0mm, 4.3mm, five models of 4.5mm, and end is fixedly connected with the yellow jacket cushion rubber, and turn is fixed in the rotating shaft two ends through the two ends mating holes.
Turn is a non-compression spring, and promptly it is at axial no compressive deformation.
The described arteria coronaria card punch of the beneficial effect of this utility model is a disposable product; But same operation of same patient can repeatedly be used; After using card punch for the first time, turn keeps lax state, can insert through the locking key that the carries through hole from handle end; After turn is locked, reuse.
The inverted cone stainless pin can prevent that in use the tissue after the last punching from coming off.
It is effective to punch, and the tissue adhesion after avoiding punching causes blood vessel wall damaged.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand this utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to this utility model; Constitute the part of this utility model; Illustrative examples of this utility model and explanation thereof are used to explain this utility model, do not constitute the improper qualification to this utility model, wherein:
Fig. 1 is the inside configuration sketch map of this utility model embodiment;
Fig. 2 is the side view of this utility model embodiment.
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
The specific embodiment
Obviously, the many modifications made based on the aim of this utility model of those skilled in the art and the variation protection domain that belongs to this utility model.
Embodiment 1: like Fig. 1-shown in Figure 2,
The purpose of this utility model provides a kind of cardiac operation arteria coronaria card punch.
The card punch main body, the front portion links to each other with sleeve pipe 7, and sleeve pipe 7 is connected with the rotating shaft 4 of rear end; Rotating shaft 4 terminal grooves are fixed a yellow jacket cushion rubber 6, rotating shaft 4 outer casing spring circles 5, turn 5 two ends extensions; Be fixedly connected respectively at rotating shaft 4 two ends corresponding apertures; External fixation is in turn 5 both sides respectively for shell A9, shell B3, and the disk card of rotating shaft 4 afterbodys is assigned in shell A9, shell B3 cooperates in the circular groove of forming
The key 1 of screwing connects rotating shaft 4, connects shell A9 and shell B3 simultaneously;
The key 1 of screwing can be placed separately, can be from shell A9, the terminal insertion of shell B3 mating holes.
The key 1 of screwing can be placed on in the packing box, takes out the installation back during use and becomes one with this utility model.
The tip of card punch main body is an inverted cone stainless pin 8, closely is connected with the card punch main body.
Rotating shaft 4 front ends link to each other with sleeve pipe 7, and sleeve pipe 7 external diameters are divided into and are 3.5mm, 3.8mm, 4.0mm, 4.3mm, five models of 4.5mm, and rotating shaft 4 is fixedly connected with yellow jacket cushion rubber 6, and turn 5 is fixed in rotating shaft 4 two ends through the two ends mating holes.
Turn 5 is a non-compression spring, and promptly it is at axial no compressive deformation.
The card punch main body refers to the device that sleeve pipe, stainless pin, rotating shaft etc. are formed, and being locked through steady pin 2 connects shell A9 and shell B3.
Described arteria coronaria card punch is a disposable product; But same operation of same patient can repeatedly be used; After using card punch for the first time, turn keeps lax state, can insert through the locking key that the carries through hole from handle end; After turn is locked, reuse.
As stated, the embodiment of this utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of this utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of this utility model.
