Abstract
A heart stabilizer comprises a crank (1), a working arm (2), a working hand (3), a base (4) and a handhold (5), wherein the base supports the crank and the working arm while the crank and base are connected via a screw between, the crank, base, working arm and working hand are combined through a steel rope to form the heart stabilizer (image 1) which is fixed on the sternal retractor which adjusts the position of the working arm (2) and the working hand (3) according to different surgical positions, the crank is twisted tightly when the position is ensured, the positions of working arm and working hand are fixed, the working hand (3) can stably fix targeted vessel of coronary artery and also rotate around itself according to the mating position of the coronary artery, the target vessel of coronary artery can be adjusted to fitful position through rotating the working hand (3). The crank (1), working arm (2) and working hand (3) are provided at loosening condition after surgery. The heart stabilizer can be fetched when drawing the handhold (5), which is fit for bypass surgery of non-stop jumping coronary artery.
Description
Technical field
This utility model relates to a kind of cardiac stabilizer, is applied to department of cardiac surgery beating heart bypass operation of coronary artery.
Background technology
Coronary atherosclerotic heart disease is the main killer of harm humans health.China's Incidence of CHD is higher, and increases year by year, annual nearly 10000 examples of row coronary bypass patient that need, and wherein, the beating heart bypass operation of coronary artery accounts for 40%.At present, all use the cardiac stabilizer of import to carry out the beating heart bypass operation of coronary artery.Develop home-made cardiac stabilizer, the blank of filling up China's this respect is very necessary.
There is following shortcoming in the cardiac stabilizer that uses at present: 1, cardiac muscle is usually damaged in compressing place in the pressure angle of cardiac stabilizer, and rupture of heart appears in individual patients, and is hemorrhage, to acute heart tamponade.2, in the beating heart coronary bypass, the difficult branch's blunt edge that circles round of finishing of minority props up and prop up when putting up a bridge darker centre, and the working arm length of cardiac stabilizer is usually not enough, brings very big difficulty to bridging.3, present a kind of cardiac stabilizer only can be applied to a kind of sternal retractor.
Summary of the invention
We have carried out technological improvement at the requirement of beating heart bypass operation of coronary artery and the deficiency of import cardiac stabilizer.
1. work hands: work hands (3) is a key technology of improving design.(Fig. 2,3-3, Fig. 3 3-9) slightly upwarp work hands front end, can prevent to puncture heart.The work surface of work hands is designed to the cylinder of different radii, and (Fig. 2,3-5, Fig. 3 3-10), rather than linear contact, reduce the destruction to heart greatly.(3-12), the frictional force of increase and heart can make work hands (3) along with heart is beated together for Fig. 2,3-6, Fig. 3, being beneficial to operation and carrying out to add a plurality of disc boss on work surface.Level and smooth configuration design (Fig. 2,3-1, Fig. 3,3-7), hanging wire when avoiding performing the operation.The work hands is easy to installation and removal, simultaneously can 360 ° of rotation, and work hands single armed again can self axial rotation, helps clinical practice.
2. working arm (2): utilize the joint principle, (Fig. 4 connects with most balls between 2-1) the working arm tube, and 360 ° of scopes are rotated flexibly.And working arm tube external diameter (Fig. 4,2-1) and sphere diameter (Fig. 5 2-6) is different size, like this design not only attractive in appearance but also can weight reduction.Working arm length than import step brachium 2cm about, to overcome working arm curtailment part in indivedual coronary artery bypass.
3. base: base (4) support handle (1) and working arm (2), and handle (1) coupling part upwarps certain angle, but the distance of swelled handle and base like this, be convenient to operation.Base and operation frame standing part are designed to the scalable size, are beneficial to be installed on the various sternal retractors.Overcome the deficiency that a kind of cardiac stabilizer only can be applied to a kind of sternal retractor.And loading and unloading are simple and convenient as long as spurring handle (5) can realize.
That this utility model uses is stable, safety, convenience, is more conducive to the patient and carries out the heart beating bypass operation of coronary artery.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is this utility model work right hand sketch map;
Fig. 3 is this utility model work left hand sketch map;
Fig. 4 is this utility model linking arm sketch map;
Fig. 5 is this utility model union joint sketch map;
Fig. 6 is this utility model handle sketch map;
The specific embodiment
Below in conjunction with accompanying drawing and example this utility model is further specified.Fig. 1 is a sketch map of the present utility model, is made up of handle (1), working arm (2), work hands (3), base (4) and handle (5) five parts.Base (4) support handle (1) and working arm (2) connect with screw rod between handle (1) and base, link into an integrated entity by steel wire rope handle (1), base (4), working arm (2) and work hands (3) again.
Cardiac stabilizer is fixed on the sternal retractor,, regulates the position of working arm (2) and work hands (3) according to the difference of operative site.After the position is determined, handle (1) is screwed, the position of working arm (2) and work hands (3) is fixed motionless.Work hands (3) also can be around self axial rotation, and according to the identical position of coronary artery, rotary work hands (3) is adjusted to the best position that appears.Simultaneously, use 20ml band needle applicator flushing arteria coronaria stoma site, make to appear good, be beneficial to operation and finish smoothly.After the operation, release handle (1), working arm (2) and work hands (3) are in relaxed state, and simultaneously, pulling handle (5) takes off cardiac stabilizer.
Claims (4)
1. a cardiac stabilizer is characterized in that being made up of handle (1), working arm (2), work hands (3), base (4) and handle (5) five parts.Base (4) support handle (1) and working arm (2) connect with screw rod between handle (1) and base (4), link into an integrated entity by steel wire rope handle (1), base (4), working arm (2) and work hands (3) again, constitute cardiac stabilizer.
2. cardiac stabilizer according to claim 1 is characterized in that work hands front end slightly upwarps 10-30 °, and the work surface of work hands is designed to the cylinder of different radii, adds a plurality of disc boss on work surface, level and smooth configuration design.
3. cardiac stabilizer according to claim 1 is characterized in that working arm tube external diameter and sphere diameter are different size, about working arm length 215mm.
4. cardiac stabilizer according to claim 1, it is adjustable to it is characterized in that base and sternal retractor standing part are designed to, and pulling handle back half-twist can be fixed in various sternal retractors; Base support handle and working arm and handle coupling part upwarp certain angle, the distance of swelled handle and base.
