Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly belongs to a repeating clip applier capable of being provided with a tissue clip bin.
Background
Tissue or vessel closure is a common procedure in surgical procedures, and is usually performed by using hemostats, electrocoagulation clamps, sutures or tissue clips to prevent bleeding. With the development of minimally invasive surgery, the advantages of small trauma and quick recovery are accepted by more and more doctors and patients, however, the minimally invasive surgery brings certain difficulties to the operators due to the narrow space and the narrow visual field. The tissue closure clip is mainly used for clamping and closing blood vessels to stop bleeding or closing tubular tissues in surgical operations, including medium and small arteriovenous vessels, bile ducts and the like, and the number of the ligation clips used in each operation is different from 2 to 15. Conventional operation is packed into a tissue clamp by the nurse and is given the doctor before the operation, the doctor inserts the pincers of giving the doctor and inserts the puncture ware passageway, accomplish tissue clamp closed back, take out the pincers of giving the doctor again, by nurse's clamping second tissue clamp, so relapse, every completion is executed and is pressed from both sides, need very long time, the operation time has been prolonged, and the pincers of giving the doctor repeatedly the human body of cominging in and going out, it is very big to human body damage, the risk has been increased, consequently, need a device that can execute the clamp in succession, guarantee that the pincers of giving the doctor need not frequently pass in and out at the operation in-process.
