Abstract

The invention relates to medicine, namely neurosurgery, and can be used for operations for tumors, inflammatory processes and traumatic brain damage with internal hydrocephalus. The purpose of the invention is to increase the reliability of fixation of the catheter. The cannula contains a soft, elastic, for example, pyrogen-free, hollow tube, a spherical retainer formed of segments fastened with a spring ring with a slit, whereby there are slots between the segments intended for inserting straight or curved needles into them, the ends of which are fixed to the upper the edge of the sleeve mounted on the non-working end of the tube is movable. In order to puncture and drain the ventricles of the brain after milling, a spherical fixture is placed into the hole in the skull of a hole at the appropriate point (Cohera, Dandy). Then, an elastic tube is introduced through it with the help of a metal mandrel to a certain depth corresponding to the mark made on the tube. The sleeve, fixed at the level of the mark, is oriented so that the working ends of the needles fall into the corresponding slots between the segments. After the needles are inserted into the spongyous layer of the bone, it ensures rigid fixation of the soft cannula, puncture and examination is carried out. The catheter is then removed. If it is necessary to perform ventricular drainage to correct liquor circulation, the needles are removed from the spongy layer and slits, the ring is removed, the distended segments are removed and the mandrins are removed, the tube is fixed on the sleeve and the ventricles are drained. 3 of FIG.

Description

The invention relates to medicine, namely, neurosurgery, and can be used for operations on tumors, inflammatory processes and traumatic brain damage with internal hydrocephalus for puncture and drainage of the ventricles.

The aim of the invention is to improve the reliability of fixation of the catheter.

FIG. 1 shows a general view of the catheter; in fig. 2 - spherical lock, top view; in fig. 3 - a segment, side view in section.

The catheter contains a soft, elastic, for example, pyrogen-free, tube 1 with a blind working end, on the side surface of which there are through holes 2, a spherical clamp 3, made with

fixed of rigid segments 4, fastened by a spring ring 5 with a slot 6, so that between segments 4 there are slots 7 designed to insert straight or curved needles 8 into them, one end fixed in the sleeve 9. The sleeve is installed on the non-working end of tube 1 s the possibility of vertical movement and rotation around tube 1. In the upper and lower parts of each segment 4, arc-shaped notches 10 are made, which when connecting segments 4 into a sphere, form holes at its poles 11 for insertion of tube 1, and at the equator of each segment 4-coagulant a groove 2 for receiving therein ring 5.

A catheter is used as follows.

After milling at the appropriate point (Kocher, Dandy), a spherical retainer 3 is placed into the hole of the skull. Then, through the holes 11, the elastic tube 1 is inserted through the retainer 3 with a metal mandrel (not shown) in a certain direction to the depth corresponding to on tube 1. Sleeve 9 is advanced to this mark and secured. The catheter is pushed through retainer 3 so that the free ends of the needles 8 fall into the corresponding gaps between segments 4. After the needles have been inserted and inserted into the spongy bone layer that provides rigid fixation of the catheter, puncture and examination of the ventricles are performed, after which the catheter

removed. If necessary, check, 5

Day of ventricular drainage to correct for liquorocirculation, needles 8 are removed from the spongy layer and retainer slits 7, the ring 5 is removed, the disintegrated segments 4 and the mandrel are removed, and the tube 1 is fixed on the sleeve 9 and the ventricles are drained.

The proposed catheter was clinically tested in the treatment of patients with tumors, inflammatory processes, traumatic brain injuries with internal hydrocephalus. The results obtained with the use of a catheter are as follows: out of 22 patients, 21 (91%) of the puncture were performed successfully, subarachnoid hemorrhages were observed only in one patient. No signs of damage to the subcortical nodes and inconsistent drainage due to the displacement of the catheter were observed.

Claims (1)

  1. Claims A cerebral ventricle catheter, comprising an elastic tube with a blind working end and holes in the side wall and a spherical fixator, characterized in that, in order to increase the fixation reliability of the catheter, the fixture is made of composite rigid segments fastened with a spring ring to form slots between them, and at the non-working end of the tube the sleeve is mounted with the needles fixed in it, the free ends of which are bent outwards to interact with the slots.
