Abstract

The inventive nasal speculum has a connecting piece (8, 12, 14) for a flexible tube (13) on at least one of its branches (1, 2), said flexible tube being provided for removing smoke. The connecting piece (8, 12, 14) opens out inside a hollow space (10) which is provided on the inner surface of the branch, adjacent to the separation plane (9) between the branches (1, 2).

Description

Nasal

The invention relates to a nasal speculum, as is commonly used by ear, nose and throat specialists for spreading the nostrils when Rhinoscopy. Such an instrument is constructed basically like a reverse-acting pincer, that upon squeezing of the pivotally interconnected gripping spars, between which a spreading spring is, are moved apart, the measures provided for the engagement into the nostril beak-shaped ends. These ends, also called sectors, are partially hollowed out on its inside, so that a produced to the separation plane between the sectors and upwardly open cavity which allows the physician a better view of the nasal interior and also creates space for manipulation on site.

For operations with laser cuts in the nasal cavity for the purpose of reduction in the nasal turbinates or the like. it comes through the burning of the affected tissue to a smoke, through which the insight between the branches of the nasal speculum is impaired, so that an observation of the operating field can only be restricted.

Better conditions may be achieved that is provided as in other operations where laser instruments are used, an additional extraction of the resulting combustion gases. To this end, associated suction hoses are used with a suction unit whose suction ends are brought as close as possible to the origin of the flue gases. but a transfer of this method to the nasal cavity is ruled out because the visual obstruction would likely exacerbated by the suction in such close engagement area.

In a known nasal speculum (DE-company publication: Karl Storz GmbH & Co., laser endoscopes and instruments for Oto-Rhino-Laryngology, 5th edition 1/95, page ORL-LAS 37) is in the formed cavity between the branches a Rauchabsaugrohr mounted, which serves for sucking the produced during laser treatment smoke. By Rauchabsaugrohr the view of the surgeon is further hampered. When using a tubing with a small cross section, although the visual obstruction is less; for it but the withdrawn smoke volume is inadequate.

In addition, a vaginal speculum known (WO90 / 03813), wherein one or both branches are double-walled to form a vaulted chambers. For the removal of solid, liquid and gaseous by-products operation these chambers each have a perforated inner wall and an outlet connected to the outer wall near the outer end of the suction sectors. Such indirectly via the said chambers out and removed from the surgical extraction is not transferable to the cramped conditions in a nasal speculum.

In contrast, the present invention has for its object to realize a fume suction during laser operations in the nasal cavity in an effective manner as possible in order to allow a substantially unobstructed observation of the engagement area, without the required by the engagement manipulation of the physician be hindered. This object is achieved in a nasal speculum with a connection piece for a serving the flue tubing at least one of its branches characterized in that the connection piece is externally connected to the sector and opens at the inside thereof within a prescribed therein to the separation plane between the sectors adjacent cavity ,

The sectors of a nasal speculum typically form on its inner side a common cavity of which is provided in the context of the invention, as a preferred location for connection of the flue. To this end, there opens the nasal speculum provided on connecting piece for serving the flue hose.

In order to hinder the activity of the doctor as little as possible, it is advantageous that the connection piece is connected respectively to the branch of the rail facing away from the thumb; based on the position of engagement of the nasal speculum when this is right handed, the right, while left-handed, the left branch of the nasal speculum.

The external device connected to the branch connecting piece is appropriately guided in the direction of the branch to the rear, where it ends with a curvature toward the bottom. In this way it is ensured that the connected to the connection port tubing does not hinder the attending physician.

A further advantageous possibility for the design of the connection piece is that this is guided along the outside of the branch and the spar. Such extended by a connecting piece, it is possible to place the hose line connected thereto far outside the field of view of the attending physician. In the context of this consideration will be apparent to the connection of the hose line, two preferred locations in that the connecting piece branches off transversely to the spar either of its portion above the joint, or from the lower end thereof.

that liquid is sucked from the nasal cavity in the connecting piece in order to avoid, it may be expedient that the connection piece in the immediate vicinity of its outlet opening has a deflecting lip, through which its mouth opening is covered towards all or part of the front end of the branch.

In terms of the above proposed training and routing of ZAnschlußstutzens is advantageous that this is formed as a socket piece of metal. Thus it can be in a nasal speculum easily mounted in such a way that the respective sector is pierced in the area of ​​the cavity defining branch wall and in that inserted into the resulting opening the mouth of the aspirator and these there-sealing, for example by soldering, is connected.

A particularly simple embodiment can consist in that the connection piece connected to the tubing or is constructed as the integral portion and is connectable to an opening of the branch by means of a hose connector. The opening may be formed as a simple hole, one in which a flexible tube can be used directly with its hose connector; the opening can for example also contain an internal thread into which an external thread provided with a connection piece can be screwed as a connecting part of a hose line.

It goes without saying that connection piece and / or hose can either be attached thereto after completion of the nasal speculum or that the connection piece from the outset, that is integrated in the preparation of nasal speculum in the shape of the branch and / or of the spar. Such a possibility would be for example, the hollow design of the branch and / or of the spar, or a part thereof.

With regard to further embodiments of the invention, reference is made to the following drawing description. The drawing shows embodiments of the invention respectively in a perspective view, namely

FIG. 1 shows a nasal speculum for a right with connecting piece on the right sector,

Fig. 2, the nasal speculum according to Fig. 1 as seen in the view of the user, and

Fig. 3 seen a side view of FIG. 2, based on the image view from the right.

Referring to FIG. 1, a nasal speculum has a right and a left sector 1 sector 2. The two branches 1, 2 are respectively at the upper end of a right spar 3 and a left beam 4 applied. The members 3, 4 are supported via a hinge 5 against each other and settle downwardly in the form of handles on, which are provided on their outer side with a surface structure 6 for improving the grip. The two members 3, 4 are spread apart between their handle-forming lower portions by means of a two-membered spreading spring 7, so that in the rest position of the nasal speculum whose two branches 1, 2 in the area of ​​their common parting plane 9 (Fig. 2) abut one another.

While in Fig. The nasal speculum is illustrated in the spread position 1, there is shown in FIGS. 2 and 3 in the closed rest position. Accordingly. 1 are added to 3 for the same parts and the same reference numerals in FIGS.

In the drawing, a conventional right-handed version of the nasal speculum is shown, ie the doctor holds the speculum with his right hand and guides the working tool, for example a laser-cutting device at a turbinate reduction with the left hand between the two branches 1, 2 therethrough. A connecting piece 8 on the right sector 1 is in this case on the side opposite the cutter side so that an obstacle to the manipulation of the physician is excluded. This is true for operations in each of the two nostrils, whereby the connecting piece 8 is in the case of an intervention in the left nostril on the side of the left nostril, while the connecting piece 8, there is in the case of an intervention in the right nostril on the side of the nasal septum , The connection piece 8 is guided so closely to the outside of the sector 1 so that the engagement of the two branches 1, is not impeded in each nostril. 2 The connection piece 8 is also formed long enough so that its terminal end is always located for the connection of the tubing outside of the nose, where a necking of the tubing, which is usually designed as a flexible silicone tube, is not to be feared. At the free end of the suction line is a suitable (not drawn) suction unit, for example, connected with a suction fan filter which generates the necessary negative pressure.

So the doctor will not be blinded by light reflections, it is expedient to design not only the nasal speculum itself but also the connection piece of a metal with non-glare, for example, burnished or matt anodized surface.

It has been apart for reasons of drawing simplification of them to represent also a left-handed version. Starting from the illustration of FIG. 1 is a left-handed embodiments would mean that the connection piece is not connected to the right branch 1 but on the left sector. 2 An acquisition of both embodiments would also have the advantage that in each case that nasal speculum could be used, wherein the connecting piece 8 adjacent the easily deformable nose is located, so that in both nostrils an equally large field of view would be ensured.

In the view according to Fig. 2 clearly shows the upwardly open, to the common separation plane 9 adjacent cavity 10. In the right branch formed by the half of the opening 1 11 of the connecting piece 8 recognizable.

Figs. 2 and 3 show an alternative to the connecting piece 8 is a drawn by broken lines 12 variant with extended connection piece at the free end of the hose 13 is connected. To Fig. 3 is not drawn as a further variant 14 with dash-dotted lines, a connecting piece, which is extended to the lower end 15 of the handle portion of the spar 3. In this case, the connected hose line there 13 is completely out of sight of the doctor, while he uses the nasal speculum.

Characterized in that the suction mouth 11 connecting branch 8, 12, 14 is introduced in the region of the cavity 10 as far as possible to the site of smoke formation in the application of laser cutting devices inside the nasal cavity of, an effective smoke evacuation can be achieved, so that the view of the operation area, for example, is possible without hindrance in the case of nasal turbinate reduction.
