SU1344315A1 - Dilator of inferior nasal passage - Google Patents

Abstract

To reduce trauma and improve visibility, the operating floor of the expander contains two braces 1, 2, connected by a hinge 3, and a working sponge narrowed, and a shorter 4 and an elongated 5, have a spiral shape clockwise relative to the branches. Both jaws 4, 5 in the closed state form a funnel-shaped channel 6, curved in the direction of the smaller sponge. 2 Il. Ate with 4 GS CPUS.

Description

The invention relates to medical technology, in particular, devices for expanding cavities, in particular, extensions of the lower nasal passage during endon. . sator 8. When the expander is entered like this,

The aim of the invention is to reduce trauma and improve visibility.

FIG. 1 shows the expander in the open operating position; in fig. 2 - the same, in a closed position when introduced into the lower nasal passage.

The lower nasal dilator contains two branches 1 and 2, connected by a hinge 3 and having narrowing working jaws: - shortened 4 and. if the latch 8 extends beyond the ridge 9 of the pear-shaped hole, then the latch 8 supports the sponge 4 on the ridge 9 of the pear-shaped hole and, pressing the branch 1 to the branch 2, expose the dilator. Since the abutment surface of the sponge 5 repeats the typical shape of the surface of the inner wall of the inferior nasal concha, its pressure on soft tissues is uniform. Produces atraumatic expansion

5, having a spiral shape with from - j j the lower nasal passage to the side and upwards

clockwise relative to branches. Both jaws 4, 5 in the closed position form a funnel-shaped channel 6, curved due to the bending of the jaws 4 and 5 to the side of the outer wall 7 of the lower nasoproximal end.

The expander provides a good view of the outer wall of the inferior nasal passage, since the shortened sponge does not obstruct the view and does not allow the expander of the outward stroke, i.e. towards the smaller sponge. 20 slipping from the nasal passage because

The proximal end of the sponge 4 is tapered and has an additional bend forming a clamp 8 for holding the sponge over the ridge 9 of the pear-shaped hole.

fixes it in the longitudinal direction. This facilitates the operation, reduces the voltage on the surgeon's hand, reduces trauma to the mucous membrane and soft tissues of the inner wall of the nasal spongy sponge 5, has on its procina, avoids its fracture,

at the extreme end, the support surface 10 is in the form of a tapered conical helix which, in a closed position, covers the proximal end of the sponge 4.

DETAILED DESCRIPTION OF THE INVENTION The dilator of the lower nasal passage, containing two pivotally connected branches, the Extender operates as follows. 4 in a closed position. In this case, the spiral conic surface overlaps the latch 8. 35 A funnel-shaped channel, characterized in that, in order to reduce traumatization and improve the view of the operative floor, the sponges are made of different lengths and are bent in the direction of the lesser of them, with the large sponge having a spiral shape clockwise relative to the expander branch. The sponge is inserted deeper, it is slightly rotated, and the supporting surface 10 pushes away the soft tissues of the nasal concha, widening the gap for free passage of the latch 8. When the dilator is inserted like this,   sator 8. When the expander is entered like this, that the retainer 8 extends beyond the ridge 9 of the pear-shaped hole, then the retainer 8 supports the sponge 4 on the ridge 9 of the pear-shaped hole and, pressing the branch 1 to the branch 2, expose the expander. Since the abutment surface of the sponge 5 repeats the typical shape of the surface of the inner wall of the inferior nasal concha, its pressure on soft tissues is uniform. Produces atraumatic expansion j j lower nasal passage to the side and upwards lower nasal passage to the side and upwards the proximal end. The expander provides a good view of the outer wall of the inferior nasal passage, since the shortened sponge does not close the view and does not allow the expander to fix it in the longitudinal direction. This facilitates the operation, reduces the voltage on the surgeon's hand, reduces trauma to the mucous membrane and soft tissues of the inner wall of the nasal conch, avoids its breakage, Claims of the lower nasal dilator, co35 A funnel-shaped channel, characterized in that, in order to reduce traumatization and improve the view of the operative floor, the sponges are made of different lengths and are bent in the direction of the lesser of them, with the large sponge having a spiral shape clockwise relative to the expander branch.
