Abstract

The utility model relates to presser foot of heart antihunt means comprising a circular connector, left and right pins, a metallic presser side opening, a plastic presser part and a connecting tube, is applicable to non-stop jumping coronary artery bypass surgery, in accordance with the anastomotic portion of a coronary artery bleed vessel during the operation, the presser foot is capable of rotating 360 degree to accommodate the optimum dewing position for working arms and presser foot, wherein the pressure foot provided under about 200 centimeter aqueous negative pressure from a far-end of the connecting pipe is adsorbed to cardiac muscle around the target blood vessel hard. Taking crown vein bypass surgery with the heart beating. After the operation, loose the hand handle, thereby the working arm maintains the pressure feet to become a flabby status, simultaneously draws the handle to take off the heart antihunt means. The heart antihunt means presser foot is applicable to non-stop jumping crown vein bypass surgery.

Description

The cardiac stabilizer presser feet

Technical field

This utility model relates to a kind of cardiac stabilizer presser feet, is applied to appear the arteria coronaria target vessel in the department of cardiac surgery beating heart bypass operation of coronary artery.

Background technology

Heart disease has become the maximum killer of harm humans health, wherein the harm maximum of coronary atherosclerotic heart disease.China's Incidence of CHD is higher, and increases year by year, the annual need more than row bypass operation of coronary artery patient 10000 examples, and wherein, the beating heart bypass operation of coronary artery accounts for 40%, and the operation example number of coronary heart disease increases severely year by year.At present, domestic each hospital all uses the cardiac stabilizer of import to carry out the beating heart bypass operation of coronary artery.In conjunction with cardiac stabilizer, develop home-made cardiac stabilizer presser feet, to fill up the blank of China's this respect.

There is following shortcoming in import cardiac stabilizer presser feet in the use:

1, the presser feet of cardiac stabilizer can not 360 ° of rotations, bring a lot of inconvenience to bypass surgery.

2, because negative pressure to the effect of cardiac muscular tissue, is usually damaged cardiac muscle at the presser feet place, hematoma appears in individual patients.

3, the part patient is owing to myocardium edema or myocardial surface hyperliposis, and the cardiac stabilizer presser feet usually can not be satisfied with and be appeared the arteria coronaria target vessel, is difficult to be preced with vascular anastomosis.

Summary of the invention

At the deficiency that import cardiac stabilizer presser feet in the beating heart bypass operation of coronary artery exists, the purpose of this utility model provides a kind of cardiac stabilizer presser feet, and external product is carried out technological improvement.

1. the cardiac stabilizer presser feet of our design links to each other in the cardiac stabilizer working arm by circular union joint, and whole presser feet is the metal material of one, and plastics are neutralized foot section insertion metal presser feet and become one, but held stationary is in heart surface.

2. link to each other in the cardiac stabilizer working arm by circular union joint, can 360 ° of rotations.

3. left and right sides foot can be arbitrarily crooked according to heart surface.

4. plastics are neutralized foot 5 circular depressed, inserts the metal presser feet and becomes one, and the presser feet radian is consistent with heart surface and can adjust.

This utility model presser feet uses flexibly, safety, convenience, is more conducive to the exposure that the patient carries out target vessel in the heart beating bypass operation of coronary artery.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further specified.Fig. 1 is the sketch map of this utility model cardiac stabilizer presser feet: neutralize foot section (4) and connection tube (5) is formed by circular union joint (1), left and right sides foot (2), metal presser feet and side opening (3), plastics.

According to the difference of operative site, regulate the position of working arm and regulator presser feet.After the position was determined, the regulator presser feet was by the about 200cmH of connection tube far-end ₂The vacuum suction of O is adsorbed on the target vessel cardiac muscle on every side firmly, and handle is screwed, and the position of working arm and regulator presser feet is fixed motionless.The regulator presser feet also can be around self axial 360 ° of rotation, and according to the identical position of coronary artery, the rotation presser feet is adjusted to the best position that appears.Simultaneously, use CO ₂Blowpipe sprays to anastomotic stoma by aerosol, fully appears the arteria coronaria anastomotic stoma, is beneficial to operation and finishes smoothly.After the operation, release handle, working arm and regulator presser feet are in relaxed state, and simultaneously, the pulling handle takes off cardiac stabilizer.

Claims

1. cardiac stabilizer presser feet, link to each other in the cardiac stabilizer working arm by circular union joint, it is characterized in that by circular union joint, left and right sides foot, metal presser feet and side opening, the foot section neutralized by plastics and connection tube is formed, left and right sides foot is respectively plastics and neutralizes the foot section and insert the metal presser feet and become one, left and right sides foot respectively has five side openings, but held stationary is in heart surface.

2. cardiac stabilizer presser feet according to claim 1 is characterized in that linking to each other in the cardiac stabilizer working arm by circular union joint, can 360 ° of rotations.

3. cardiac stabilizer presser feet according to claim 1 is characterized in that left and right sides foot can be arbitrarily crooked according to heart surface.

4. cardiac stabilizer presser feet according to claim 1 is characterized in that plastics neutralize foot 5 circular depressed are arranged, and inserts the metal presser feet and becomes one.
