RU85086U1 - INTUBATION KIT FOR BICANALICULAR DRAINING OF TRAUMATIC WAYS - Google Patents

Abstract

An endotracheal kit for bicanalicular drainage of the tear ducts, consisting of a flexible cylindrical tube and a fishing line-conductor, characterized in that the components of the endotracheal set are not interconnected, the fishing line-conductor has a length of 400 mm, and the drainage tube is 200 mm, tapered at the ends and made of x-ray contrast polyurethane.

Description

The utility model relates to the field of medicine, and more specifically to ophthalmology.

Known intubation kit (IN) manufactured by FCI (France) (Davydov D.V. et al. Method for bicanalicular intubation of elastic stents with endoscopic dacryocystorhinostomy // Refractive Surgery and Ophthalmology. - 2005, Volume 5. - No. 1. - P.56 -60).

However, this device has several disadvantages: the presence of postoperative complications in the form of granulation, a toxic-allergic reaction to the material (silicone) from which the drainage is made, leading to relapse of the disease, the complexity and high cost of manufacture and use - polypropylene guides are soldered into a silicone tube, which with a slight effort applied during intubation can prematurely separate from the drainage and its further use is impossible.

The technical problems solved by the utility model are the reduction of postoperative complications and the normal functioning of the lacrimal system both with intubation of the natural and newly created tear duct during dacryocystorhinostomy, as well as the simplification of the drainage procedure and the possibility of radiological control of the drainage position.

These technical problems are solved by the fact that the intubation set consists of two parts: a flexible cylindrical tube conically narrowed at the ends, 200 mm long and 1 mm outer diameter, and a fishing line (PL) 400 mm long, not interconnected. The material of the tube serving as drainage is X-ray contrast polyurethane, used in the production of subclavian and jugular vein catheters.

ID for bicanalicular drainage of the tear ducts is illustrated by figures 1, 2.

Figure 1 presents a General view of a utility model, where 1 is a drainage tube (DT), 2 is a fishing line-conductor.

Figure 2 shows the location of drainage in the lacrimal passages, conducted through dacryocystorhinostoma 3 or the lacrimal-nasal canal 4.

Work with ID for bicanalicular drainage of the tear ducts is as follows:

Transcanalicularly through the lower lacrimal opening dilated by conic probes, the Ritleng probe equipped with an internal canal is inserted into the lacrimal-nasal canal or dacryocystorhinostoma. Through the probe, a colored LP is carried out, the end of which, under the control of the rhinoscope, is removed from the nasal cavity using a Ritleng hook. The Ritleng probe is removed. From the vestibule of the nose, it is worn before the end of the fishing line from the lower end of the DT. Holding the drainage tube on the LP, pull the opposite end of the LP until the upper end of the drainage tube is removed from the lower lacrimal opening. Through the upper lacrimal opening dilated with conical probes, a Ritleng probe is inserted into the lacrimal-nasal canal or dacryocystorhinostoma. Through the probe, a colored LP is carried out, the end of which, under the control of the rhinoscope, is removed from the nasal cavity using a Ritleng hook. The Ritleng probe is removed. The upper end of the drug is introduced into the DT until it is removed from the lower end of the tube. While holding the tube on the fishing line, they pull it on the opposite end of the fishing line, while the upper end of the pipe along with the fishing line is introduced through the upper lacrimal opening into the lacrimal duct, and then into the lacrimal-nasal canal or dacryocystorhinostoma, the nasal cavity and is brought out through the vestibule of the nose. Fishing line is removed from the cavity of the DT. The ends of DT are trimmed at the level of the vestibule of the nose.

Example 1. Patient M., 42 years old, diagnosis: obstruction of the tear ducts at the level of the mouth of the lacrimal tubules on the right. Complaints of constant lacrimation from the right eye. An attempt to rinse the tear ducts is unsuccessful. The diagnosis of obstruction of the tear ducts at the level of the mouth of the lacrimal tubules is confirmed by functional tests and diagnostic antegrade sounding of the lacrimal tubules. After dissection of adhesions and strictures at the mouth of the lacrimal canaliculi by the aforementioned method, bicanalicular drainage of the tear ducts was performed, in which the ends of the DT are removed from the nasal cavity through the mouth of the nasolacrimal duct. The operation and the postoperative period proceeded without complications. The drainage tube is extubated 4 weeks after surgery. During control examinations throughout the observation period (12 months), the patient does not complain. Tear ducts are freely passable.

Example 2. Patient A., 56 years old, diagnosis: - chronic purulent dacryocystitis, obstruction of the nasolacrimal duct on the left. Complaints of constant lacrimation and purulent discharge from the right eye. The attempt to rinse the lacrimal passages is unsuccessful: the lavage fluid, together with the mucopurulent contents of the lacrimal sac, is released from the paired lacrimal opening. The diagnosis of dacryocystitis is confirmed by computed tomography, which revealed an increase in the size of the lacrimal sac on the right. An operation of endonasal dacryocystorhinostomy (DCR) was performed on the left, culminating in bicanalicular drainage of the tear ducts according to the above method, in which the ends of the DT are removed from the nasal cavity through the lacrimal-nasal anastomosis formed during the DCR. The operation and the postoperative period proceeded without complications. The drainage tube is extubated 1 week after surgery. During control examinations throughout the observation period (12 months), the patient does not complain. Dacryocystorhinostoma is wealthy. Tear ducts are freely passable.

Using the utility model proposed by the author allows, without resorting to complex manufacturing technology and clinical applications, to achieve a positive solution to the technical problem specified in the description.
