Description

Bladder puncture fistulization external member

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to a bladder puncture fistulization external member.

Background

The puncture drainage is generally called as percutaneous puncture drainage, namely under the guidance of an imaging device, devices such as a puncture needle, a drainage catheter and the like are utilized to perform puncture suction and drainage on pathological effusion, hematoma and abscess in a human body pipeline, a body cavity or organ tissues or fluid siltation of bile, pancreatic juice, urine and other body fluids, so as to achieve the purposes of pressure reduction and treatment. Percutaneous puncture drainage is commonly used for puncture drainage of abscess, cyst, serosal cavity hydrops, bile duct or urinary tract obstruction and intracranial hematoma at all parts of the body. When cytology, bacteriology and biochemistry detection are carried out on the extract, differential diagnosis and medication guidance are carried out, and meanwhile, local treatment such as anti-inflammation and drainage can be carried out through the drainage catheter, so that the effects of pressure reduction, anti-inflammation and the like are achieved.

The existing puncture drainage method commonly used on site is that a small incision is made after local anesthesia of a skin puncture point, a dilator is used for pre-dilation from the skin puncture point to a soft tissue channel of a lesion area, a drainage tube is pushed into an organ under the guide of perspective or ultrasound, and then a conduit and the skin are sutured and fixed through silk threads. The use of a dilator increases the size of the wound, and suturing the catheter to the skin is prone to patient discomfort.
