Description

TROAKAR for puncture epicystostomy

The utility model relates to the field of medicine, namely to urology, and can be used to perform epicystostomy.

A device for performing puncture epicystostomy, where the drainage device is an integral part of the trocar. The tool consists of a stylet with a handle and a tip. The tip is made of fluoroplastic and contains an annular groove for fixing the tube with thread, the upper part has a spherical shape. The lower part of the stylet has a ledge, which is the focus of the stylet in the sphere of the tip. The stylet ends with a pointed 3-sided. When operating the trocar, the stylet is located inside the drainage and the tip. Novikov I.F., Aleksandrov V.N., Artemov V.V. Endoscopic electrosurgery in urology. S.-N .: 2001, 88 p.

The disadvantages of the device are: the fragility of the connection of the drainage tube and the tip, the use of the tip left in the lumen of the bladder, its implementation from material that collapses during sterilization, in addition, the diameter of the tip itself significantly exceeds the outer diameter of the drainage tube, which reduces leak tightness.

A trocar is known, through the tube of which, after a puncture of the bladder and removal of the stylet, a drainage tube is inserted into its cavity, the tube is removed, the tube is fixed to the skin. Operative urology. Ed. ON THE. Lopatkina. L., "Medicine .: 1986 - 479 p.

Disadvantages: in connection with the reduction of an overstretched bladder, migration of the end of the drainage tube from the bladder is possible with the development of subsequent urinary leakage paravesically.

The objective of the utility model is to reduce the risk of complications and provide greater ease of manipulation.

a cylinder at the neximal end and having two channels at the distal end: one for urine diversion, the second with a valve for inflating the balloon.

The proposed trocar is shown schematically in FIG. 1-4, where:

1 - tube, 2 - protrusion for the stop of the handle, 3 - slot in the tube, 4 - stylet with a pointed 3-spigot, 5 - handle having a threaded connection with the stylet, 6 - channel of the Foley catheter for urine diversion, 7 - valve channel for balloon inflating.

The tool is used as follows.

A handle 5 is screwed onto the distal end of stylet 4, the stylet is inserted into the tube 1 with a slot 3 After performing a skin incision, a trocar is inserted into the lumen of the bladder, stylet 4 is removed, the Foley catheter 6 is inserted, the balloon is inflated, tube 1 is removed, catheter 6 is inserted through slot 2 , take out the drainage.

The proposed tool reduces the risk of injuries during epicystostomy drainage, minimizes the risk of slipping drainage from the tool.

Using the proposed trocar, 32 patients aged 67.1 ± 3.5 years (53 to 90 years) were urgently operated on. Surgical allowance was performed in six cases of acute urinary retention and in 26 chronic urinary retention on the background of benign hyperplasia (29 patients) and cancer (3 patients) of the prostate gland. The operation was performed under local anesthesia. There were no complications and mortality. All operated patients were activated on the day of surgery. The average bed day was 1.8 ± 0.4.

In a known manner, 11 patients were also operated on according to urgent indications. The average age was 64.6 ± 3.8 years (from 56 to 87 years). The reason for surgical treatment was acute urinary retention in four cases, chronic - in seven. As the main disease, benign prostatic hyperplasia was revealed in five patients, and cancer in the wounds. Intervention was performed under local anesthesia. IN

In two cases, cystostomy drainage was manifested from the bladder with the formation of a urinary leak into the paravesical tissue, which was the reason for the repeated operation of epicystostomy and drainage of the drain from the lower middle laparotomy. There was no mortality. The average bed day was 5.8 ± 1.9.
