Description

A kind of breastbone eyelid retractor

Technical field

This utility model relates to technical field of medical instruments, specifically, is the breastbone eyelid retractor that a kind of delayed sternal closure is used.

Background technology

Congenital heart disease is commonly encountered diseases, the frequently-occurring disease in the infant.China's congenital heart disease sickness rate has become first cause of death of child below five years old up to 8 ‰.According to statistics, approximately there is the newly-increased patient about 150,000 every year in China, and wherein the arteries of complex congenital heart defect patient accounts for 30%-40%.At present, approximately there are domestic every year 3-4 ten thousand infants to accept congenital heart disease operation, only the Heart center of Shanghai child medical center operation quantity surpassed for 3000 example/years, and wherein the success rate of operation of critical arteries of complex congenital heart defect such as the transposition of great vessel, pulmonary atresia, Single Cardiac Ventricle etc. is more than 90%.Progress along with medical science and technology, a lot of simple congenital heart diseases can be effected a radical cure by surgical operation, but the Various Complex CMH is arranged, because have diverse hemodynamics with normal children, its surgical operation therapy is one of challenging field of tool of medical circle always.

Complicated congenital heart disease infant for poor heart function, pericardium after accepting operation on heart and breastbone are closed and may be limited cardiac function, may cause interference to effective mechanical ventilation in addition, there be neonate and the young infant of severe cardiac myoedema in this point for postoperative, and the recovery of the cardiopulmonary interactive relation of immediate postoperative is even more important.The postoperative delayed sternal closure can help cyclic balance and stable ventilation situation.Therefore take in early days after surgery the strategy of delayed sternal closure very necessary and effective often to this part infant.

In operating room, the mediastinum edema, unsettled hematodinamics state and hemorrhage all be the indication of delayed sternal closure, for immediate postoperative expection hematodinamics or the unsettled infant of breathing state being arranged is a kind of optionally method.Compare with delayed sternal closure in operating room, postoperative is implemented the in close relations of urgent breastbone Reopening and high mortality in the cardiac intensive care chamber, and finish again breastbone in 4 days after surgery and close infant for most of delayed sternal closures, the danger that operative incision infects is lower.Therefore for hemodynamics and the unsettled high-risk infant of breathing state, it is vital making accurate judgment in art and finishing reliable and stable delayed sternal closure.

This important surgical method of delayed sternal closure at home, extensively confirmed to be to operate in the clinical practice of outer congenital heart disease surgical intervention and effective, can help the part critical diseased children to tide over smoothly the unsettled peri-operation period of blood circulation, treat and process and striven for valuable time and chance for further, thereby saved the life of numerous critical arteries of complex congenital heart defect infants.Along with the continuous progress of surgery operating technology, and the guarantee of the new the medical insurance system of country, increasing complicated critical children with CHD will have an opportunity to obtain operation and entangle and control, and this also makes improving of delayed sternal closure technology and standard becomes very urgent task.

Still lacking in congenital heart disease operative treatment field at present can be for the suitable delayed sternal closure equipment special of surgeon's selection, and surgeon's normal method that adopts in operation has: (1) directly sews up the skin edge; (2) adopt plastic injection syringe cutting rear distraction breastbone, edge and sternum suture are fixed, the rear skin edge of sewing up under the free skin; (3) adopt sheet rubber (generally being that the surgical glove cutting forms) and skin edge to sew up, sew up the edge and be coated with erythromycin ointment.Above-mentioned first method often can not effectively be kept the state that breastbone opens because of breastbone without support, then two kinds of methods are because need the processing equipment can prolong operating time, and the delayed sternal closure equipment shape system of simple reprocessing is lack of standardization, fixedly difficulty is large, be easy to slippage, so usually be difficult to reach stable, the reliably fixedly requirement of breastbone, this has caused very large trouble to clinical position, the more important thing is increases patient trauma, prolongation hospital stays, increase medical expense, even directly jeopardizes the life of infant.Therefore, need a kind of easy to use, reliable and stable breastbone eyelid retractor badly, but yet there are no report about this class eyelid retractor at present.

Summary of the invention

The purpose of this utility model is for deficiency of the prior art, and a kind of good fixing effect, breastbone eyelid retractor reliable and stable, simple in structure, easy to use are provided.

For achieving the above object, the technical scheme taked of this utility model is:

A kind of breastbone eyelid retractor, described breastbone eyelid retractor is provided with support, and described support is curved, and two ends respectively are provided with draw-in groove, and two side channel faces of described draw-in groove are vertical with the cambered surface of support.

Described support chord length 3-5cm, radian is the 10-40 degree.

Described draw-in groove is provided with upper support arm and lower support arm, respectively is provided with a through wires hole on described upper support arm and the lower support arm.

Described draw-in groove is U-shaped, and described upper support arm is shorter than the lower support arm.

Described breastbone eyelid retractor is to be made of metal.

This utility model advantage is:

1, adopts the integrated design of arc support and draw-in groove, draw-in groove can block the breastbone of riving in both sides, effectively avoid the inside and outside slippage of eyelid retractor sternal, safe and reliable, easy to use, can shorten operating time clinically, reduce wound in patient's art, avoid simultaneously because nonstandard delayed sternal closure art causes patient's secondary damage, shorten the hospital stays, reduce medical expense, and avoid the situation that directly jeopardizes infant life undesirable because of the delayed sternal closure effect or that the slippage of temporary supporting device causes;

2, draw-in groove is U-shaped, and the breastbone of riving with both sides agrees with fully, is easy to fixing and good fixing effect;

3, the upper support arm of draw-in groove is shorter than the lower support arm, and shorter upper support arm can reduce the damage to breastbone outside muscle;

4, upper support arm and lower support arm are provided with through wires hole, can sew up after placing eyelid retractor of the present utility model and fix, and be by suture that draw-in groove and breastbone is further fixing, avoids eyelid retractor to the slippage of patient's head end or foot and the slippage inside and outside the sternal;

5, the whole metal that adopts is made, and has both guaranteed the durable of eyelid retractor itself, has guaranteed again and the synestotic stability of breast and reliability;

6, support Design is arc, and chord length 3-5cm, radian are the 10-40 degree, can support breastbone to suitable kerf width.
