Technical field
The invention belongs to medical instruments fields, and in particular to flushing splashproof dress used in replacement knee in arthroplasty
It sets.
Background technique
So far from the 1970s, artificial knee joint replacement surgery obtains tremendous expansion.Only the U.S. applies every year at present
Capable artificial full knee joint transposing quantity is up to 300,000 or more.China is the big country for possessing more than 1,300,000,000 populations, according to most protecting
The estimation kept, the case for suffering from knee joint osseous arthritis and rheumatoid arthritis should be more than 30,000,000, wherein there is significant proportion
Case can reach satisfied reconstruction by artificial knee joint replacement.At present total knee replacement during surgery,
After completing osteotomy, need to be rinsed operating field with pulse flushing device, it is possible to reduce patient's postoperative ankle infection risk.
But aseptic operation list is mostly cloth in domestic operation at present, and water is easily lead to when being rinsed and is splashed on surgical paper,
And then destroy sterile, increase postoperative infection risk.It there is no the knee joint exclusively for artificial knee joint replacement design currently on the market
Slow rinse anti-splash device, most in operation to use kidney basin, simple aseptic plastic bag etc., these equipment are inconvenient to use, and anti-
Water effect is poor, takes many unnecessary troubles to assistant and operator doctor, extends operating time.So inventing a kind of knee pass
Section slow rinse anti-splash device is the common aspiration of vast joint surgery doctor.
Summary of the invention
The technical problems to be solved by the present invention are: in view of the deficienciess of the prior art, providing a kind of knee prosthesis
The flushing anti-splash device that operation uses reduces postoperative infection risk, contracting in favor of facilitating the progress of artificial knee replacement surgery
The short replacement knee in arthroplasty time.
