Description
Technical field
The utility model belongs to medical auxiliary apparatus technical field, and sleeve pipe is hardened more particularly, to a kind of PTC cyst drainages
Pin.
Background technology
Ultrasound guidance cyst drainage hardening treating mainly applies traditional PTC pins, and now domestic and international PTC pins are mainly by outer tube
And nook closing member composition, it with nook closing member is the sharp keen port of rhombus that the top of sleeve pipe, which is,.When ultrasound guidance tumour punctures, PTC is needled into
After tumour, impregnator drawing liquid connection PTC outer tube afterbodys are utilized after extracting nook closing member, most cyst fluid is taken out and is followed by impregnator injection of sclerosing agent
Such as absolute alcohol, Lauromacrogol, after the injection of sclerosing agent stipulated time, most of curing agent is pumped out using tunica pipe, stays small part
Curing agent is in blister cavities.Existing PTC needle sets have the disadvantage that：
When 1.PTC is needled into blister cavities, it is difficult to show on the ultrasound image sometimes because needle point is tiny, easily triggers puncture failure
And the severe complication such as damage periphery important organ；
2. in blister cavities after cyst fluid suction, due to shrink of capsular space, the factor such as patient's enteron aisle back pressure, cyst wall easily touches PTC sets
Trigger the complication such as cyst fluid seepage, bleeding in the sharp port of tip；
3. tumour is larger（Generally higher than 5cm）, injection of sclerosing agent after cyst fluid suction, hardener dosage cannot exceed former
1/3 or total amount of cyst volumes cannot exceed 30ml, otherwise easily trigger serious part and systemic complications.Curing agent is present
Administration mode injects blister cavities using impregnator connection sleeve pipe Aculeata, and curing agent is distributed from cannula tip gradually to surrounding in blister cavities
Infiltration, larger tumour blister cavities is big, is limited to curing agent dosage and permeability administration mode, causes trocar tip distant place capsule
Wall is difficult fully hardened, and cyst wall secretory cell can not be inactivated completely, and tumour easily recurs after treatment.
