Operation instruction

One,earlier endoscope 2 is inserted in endoscope's through hole 8, then conical head connecting rod 39 is inserted annular through-hole 7, installlens bracket 4 andconical head 3.

Two, will lackmuzzle bobbin 11 and be enclosed within on thesleeve pipe 1, aftershort muzzle bobbin 11 inserts operative site withconical head 3, advance to the target location.

Three, afterconical head 3 arrives surgery location, take outsleeve pipe 1, dismountingconical head 3 andlens bracket 4 insert bipolar shears from annular through-hole 7.

If the camera lens of four endoscopies, 2 far-ends is fuzzy by blood or fat, advanceC type ring 5 to place the camera lens irrigator, cleanoutfluid injection port 15 connects the syringe of dress 5cc normal saline, and pushing syringe sprays normal saline to clean camera lens.

Five, under the observation ofendoscope 2, pushC type ring 5 to destination organization, can regain the blood vessel trunk so that expose its branch better withC type ring 5 when needing around endoscope's 2revoling tubes 1 to placeC type ring 5.

Six, advance bipolar shears to target site, electricity coagulates and cutting vessel branch.

Seven,, cut bipolar the cutting of lock control by bipolar on the scissors handle 22 simultaneously and carry out slow TURP at last by the foot-operated surgery electric system that activates.

Eight, after operation finishes, close the surgery electric system, take outsleeve pipe 1 and bipolar shears.

When using the radial artery sleeve pipe,endoscope 2 need be insertedtitanium pipe 29 aftershort muzzle bobbin 11 enters operative site, advance the radial artery sleeve pipe to target site then, treat to take out after the radial artery sleeve pipe arrives operative site, use the collection sleeve pipe that addsendoscope 2 and bipolar shears to enter operative site at last, repeat above-mentioned four, five, six, seven, eight steps.
