Description
Technical field
The utility model belongs to the field of medical instrument technology, is related to a kind of retaining mechanism of Medical puncture instrument.
Background technique
Minimally Invasive Surgery refers to the operation using the modern medical equipments such as laparoscope, thoracoscope and relevant device progress, has
Wound is small, pain is light, restores fast superiority.Stamp card is the tool used in laparoscope or thoracoscopic operation, uses time stamp card
One end be inserted into skin, the other end needs to be fixed on skin surface.The no fixed device of most of stamp card that the country uses at present,
It is easy to sliding, loose shift during surgery, or even when appearance operation progress half, too deep show is deviate from or slid into stamp card
As seriously affecting surgical procedure, being delayed operating time.Domestic hospitals are often maintained using the method for correcting stamp card position repeatedly
Operation carries out, but merging can make stomach wall form multiple Y shape ducts repeatedly, and peritonaeum breach increases, and easily forms pneumoderm in art.
For this purpose, Chinese patent discloses a kind of stamp card [Authorization Notice No. CN204744266U] with fixed device,
Including stabbing card ontology, there are also stamp card fixers for it, and stamp card fixer includes wrapping layer and fixed agraffe device, on wrapping layer
