Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of arthroscope finger pin of the manual control with attraction channel.
Background technique
When being operated under arthroscope, to keep good inspection or surgical field of view to usually require to absorb view by aspirator
The chaff interferent of Yezhong, such as: hemorrhagic flushing liquor, the bone of intra-articular floating, cartilage and synovial membrane fragment of tissue are dug under arthroscope at present
It cuts and is provided with attraction channel with radiofrequency vaporization handle, the good visual field can be kept when using these tools.It is right under arthroscope
When the structures such as intra-articular meniscus, ligamentaum cruciatum, articular cartilage, broad-mouthed receptacle for holding liquid lip, tendon are detected, it is both needed to come using arthroscope finger pin
It completes, but there is no the finger pin product with attraction channel available at present, so when tissue is detected often because of patient's blood
The reasons such as pressure, which increases, leads to intra-articular hemorrhage or intra-articular tissue debris is more cause flushing liquor to stain with blood or muddy, seriously affect view
Open country, so that finger pin is had to after entering because can not clearly detect, taking-up uses the instrument with suction device instead and is pumped to the visual field repeatedly
Secondary merging finger pin again after clear, operation may significantly extend inspection or operating time repeatedly, increase anesthesia, wound sense
Therefore the risks such as dye, can also increase surgery cost.
Summary of the invention
The purpose of the present invention is to provide a kind of manual arthroscope finger pins with attraction channel, can carry out using finger pin
The groups such as bone, cartilage and the synovial membrane of hemorrhagic flushing liquor, intra-articular floating while checking or perform the operation under arthroscope in the absorption visual field
Fragment is knitted, provides good inspection or surgical field of view for operative doctor, to avoid passing in and out device repeatedly due to detecting because that can not understand
The waste of time caused by tool achievees the purpose that shorten operation and anesthesia duration, reduces the risks such as relevant risk and wound infection.
