Description

A kind of department of cardiac surgery drag hook

One, technical field

This utility model relates to a kind of medical equipment, a kind of cardiac operation drag hook.Be suitable for root of ascending aorta and cut back tractive aorta wall, thereby fully show the art open country of intracavity.

Two, background technology

The operation on heart that a lot of relevant aortic valves and left ventricular outflow tract view are widened all needs the row root of ascending aorta to cut, and fully shows aortic valvular ring and coronary ostium.Owing to there is not drag hook in the special-purpose aorta lumen, current a lot of patient all gets used to adopting interventricular septum drag hook tractive AAW, and art is wild to be shown to help, yet when exposing RCC lobe ring root, RCC-no corolla lobes binding site lobe ring root, right coronary artery opening, because local special dissection reason, the patient usually feels to show satisfied inadequately, thereby causes operation very awkward.Along with closing on of aging society, increasing cardiac valve degeneration patient can accept this type of operation.Aortic valve lobe ring root poor display can prolong the intracardiac repair under direct vision operating time in the art; Right coronary artery opening poor display may cause cardiac muscle to stop jumping and protect perfusion bad, and these all can be to the recovery of patient's postoperative, and especially aged patient's recovery brings adverse effect.

Three, summary of the invention

This utility model provides the special-purpose drag hook in a kind of aorta lumen, AAW after can the tractive root of ascending aorta cutting, fully show the aortic valve lobe ring root that comprises RCC, RCC-no corolla lobes binding site lobe ring root, and, certain facilitation is arranged to the demonstration of right coronary artery opening.

The technical scheme that this utility model is dealt with problems is as follows.

Drag hook in a kind of aorta lumen is characterized in that:

1) it is to be connected to form in regular turn by coupler body, the neck of hook, handle three parts.

2) front end of the neck of hook is new lunar sample arc, and size is 1/3 of diameter 2.5 ~ 3.5cm circumference, and circular arc is protruding in handle side.The overall structure of coupler body is the thick part of 1mm pipe wall that is, promptly also is arc, and arc size is consistent with aforementioned neck of hook front end arc, promptly 1/3 of diameter 2.5 ~ 3.5cm circumference; Concave surface forward, convex surface is connected with the corresponding arc-shaped sections of neck of hook front end in the transverse section of the vertical direction tube wall of the neck of hook backward; The terminal section of coupler body is the curling slightly 1mm of vertical direction forward, and is three dentations, and tooth and between cog totally 2 breach are down " U " shape, the high 1.5cm of coupler body, and " U " shape apex height of falling is about 1cm; The coupler body arc convex surface is towards handle orientations, on 2 ~ 3 width the are arranged diagonal impression that is 1mm and the transverse traveling wave Slippage that is abound with; The free edge of each of coupler body, the neck of hook is all through going rib to go sharp streamlined passivation.

Drag hook in this utility model aorta lumen, aorta clamping in art, after root cuts, the assistant puts into this utility model the aorta lumen of valve side, because the drag hook coupler body is the arcual part of pipe wall, close with the arterial wall and the lobe annular attitude of circle, therefore good with contacting of lumen of artery inwall when tractive with support compliance property, to patient foot side tractive gently, can overcome local special anatomical angulation, for the patient fully exposes RCC lobe ring root, RCC-no corolla lobes binding site lobe ring root, adjust gently again to patient lower right tractive, then can completely appear RCC ring root, make things convenient for the patient to detect and operate; Coupler body arc convex surface backward is the tractive focusing surface, and the impression and the ripple glaze of design can increase contact surface Mo Chali on it, is difficult for slippage takes place when tractive, and lifts power on can having necessarily; Utilize the damaged patient of helping on the coupler body to detect the right coronary artery opening during tractive, as do not see, then the tractive position is adjusted slightly and can be helped demonstration.This utility model can help patient's clear all lobe ring roots that appear aortic valve rapidly, and help the demonstration of right coronary artery opening, to appearing structure the relative fixed effect is arranged, make things convenient for finishing smoothly of operations such as coronary perfusion and valve replacement, thereby the saving operating time alleviates induced myocardial injury and reduces postoperative complication.

This utility model stainless steel material of drawing materials, simple in structure, processing technology is uncomplicated, and sterilization, easy to use can be adjusted curved circular Zhou Daxiao and make multiple model.

Five, the specific embodiment

Further specify concrete structure of the present utility model and using method below in conjunction with accompanying drawing.

Drag hook in a kind of aorta lumen is characterized in that:

1) it is to be connected to form in regular turn by coupler body (3), the neck of hook (2), handle (1) three part.

2) front end of the neck of hook (2) is new lunar sample arc, and size is 1/3 of diameter 2.5 ~ 3.5cm circumference, and circular arc is protruding in handle (1) side.The overall structure of coupler body (3) is the thick part of 1mm pipe wall that is, promptly also is arc, and arc size is consistent with the aforementioned neck of hook (2) front end arc, promptly 1/3 of diameter 2.5 ~ 3.5cm circumference; Concave surface (3A) forward, convex surface (3B) is connected with the corresponding arc-shaped sections of the neck of hook (2) front end in the transverse section of the vertical direction tube wall of the neck of hook (2) backward; The terminal section of coupler body (3) is the curling slightly 1mm of vertical direction forward, and is three dentations (4), and tooth and between cog totally 2 breach are down " U " shape, the high about 1.5cm of coupler body (3), and " U " shape apex height of falling is 1cm; Coupler body arc convex surface (3B) is towards handle orientations, on 2 ~ 3 width the are arranged diagonal impression that is 1mm and the transverse traveling wave Slippage that is abound with; Coupler body (3), the neck of hook (2), each free edge all through going rib to go sharp streamlined passivation.

Drag hook in this utility model aorta lumen, aorta clamping is after root cuts in art, the assistant puts into this utility model the aorta lumen of valve side, because drag hook coupler body (3) is the arcual part of pipe wall, close with the arterial wall and the lobe annular attitude of circle, therefore good with contacting of lumen of artery inwall when tractive with support compliance property, to patient foot side tractive gently, lobe annular attitude is close, therefore good with contacting of lumen of artery inwall when tractive with support compliance property, to patient foot side tractive gently, can overcome local special anatomical angulation, for the patient fully exposes RCC lobe ring root, RCC-no corolla lobes binding site lobe ring root is adjusted gently to patient lower right tractive again, then can completely appear RCC ring root, make things convenient for the patient to detect and operate; Coupler body arc convex surface (3B) backward is the tractive focusing surface, and the impression and the ripple glaze of design can increase contact surface Mo Chali on it, is difficult for slippage takes place when tractive, and lifts power on can having necessarily; When utilizing the damaged patient's of the helping tractive arterial wall on the coupler body (3), detect the right coronary artery opening, as do not see, then the tractive position is adjusted slightly and can be helped to show.This utility model can help patient's clear all lobe ring roots that appear aortic valve rapidly, and help to show the right coronary artery opening, to appearing structure have that relative fixed is tailor-made to be used, make things convenient for finishing smoothly of operations such as arteria coronaria cold-penetration, valve replacement, thereby can save operating time, reduce postoperative complication.
