Description
Technical field
The utility model relates to field of medical article technology, specially a kind of tumour one-step method puncture drainage hardens external member.
Background technique
Hepatorenal cyst is clinical common disease.The area patient Gan Shen discomfort is often resulted in, and patient's hepatic and renal function may be influenced.Mesh
Preclinical therapy mostly uses the cyst fluid under Image-guided to aspirate, medical dehydrated alcohol or (and) Lauromacrogol hardening treating method, advantage
Be: wound is small, few intercurrent disease, outpatient service can the multinomial advantage such as operative treatment so that Most patients no longer need in hospital or
Carry out conventional big operative treatment.It is treated principle and is: being a, suction tumour capsula interna liquid decompression, or repeatedly suction punching first
It washes tumour, dilutes remaining cyst fluid in tumour, reduce the content of tumour internal protein, clean cyst wall attachment protein matter or even larger
Tumour carries out catheter drainage；B, reinject medical dehydrated alcohol or (and) Lauromacrogol hardening tumour endothelial cell, endothelial cell is broken
Secreting function is lost after bad, new cyst fluid will not re-formed, to achieve the purpose that healing；C, repeatedly hardening, improves curing agent
The therapeutic effect of (curing agent: medical dehydrated alcohol and Lauromacrogol etc.)；D, using seal wire is put into plastic catheter, plastics are reduced
The side opening of the curing agent discharge of catheter port, as far as possible guarantee plastic catheter bending section has curing agent to spray in spurting,
So that curing agent is impacted cyst wall as far as possible, directly acts on cyst wall and generate better hardening treating effect.
However the puncture needle Direct perforantes hardening that currently employed Aspiration and sclerosis treatment method mainly uses, but exist
Following disadvantage: 1, after puncture needle enters tumour, directly aspirating cyst fluid, and with the reduction of cyst fluid, tumour reduces, it is possible to lead to needle
Jagged broken cyst wall causes not can be carried out hardening treating or curing agent is caused to inject except tumour, and patient generates peripheral organs damage
The serious complication such as wound, severe pain；2, due to the reduction of cyst fluid, guide whether equipment (CT or ultrasound) can not confirm puncture needle
Lead to hardening treating failure in the blister cavities of diminution and abandon hardening treating, generates medical tangle；3, it can not be rinsed
Cyst wall, thoroughly drainage cyst fluid or multiple hardening treating, curing agent are directly acted on containing the remaining cyst fluid more than protein, dilution
The concentration of curing agent, and lead to the concentration of cyst wall contact endothelial cells curing agent, cause hardening treating effect poor, patient is discontented
Meaning.
