Description of the utility model object

"Universal suction and irrigation device, preferably for operations as the ear"

The invention relates to a suction and irrigation device which can be used in all operations on the ear, starting with the removal of the mastoid process until the stapes operation is possible »His job is to suck off and rinse away while working with Instruments, especially bone chips, blood clots, pus, small tissue particles from the electric drill i.a.

Under the same aspects, this universal suction and rinsing device also for neurosurgical operations in hand surgery and for interventions in the area of the paranasal sinuses at.

There are rinsing and suction instruments for operations on the ear bek tgeworden ann, however, have been able to meet the manifold demands that must be made during an operation of such a device, only a small part.

The devices, which by a large lumen suction and and small lumen Irrigation tube marked on a handpiece are only suitable for relatively rough interventions, such as. B. to the rupture of the wart. In contrast, such devices are used for subtle operations in the middle ear through the ear canal or after the removal of the wares extension is insufficient, since the double-barreled and thus relatively massive devices while operating with the fine instruments under the magnifying glass or the microscope, restrict the already narrow field of vision even further.

The flushing and suction devices that have become known up to now have a very limited use due to their inconveniences found in the ear surgery. The "rinsing and suction handle" according to YESEEB, even after modification by WEICH-M4M, does not meet the requirements in the hearing enhancer Middle ear surgery placed on an irrigation and suction device Need to become.

field due to the double running of the approaches, the latter are for sucking and irrigation in the middle ear, z. B. too large on or between the ossicles. For the last-mentioned operations, suction tubes or irrigation cannulas according to ZÖLLNER are mostly used, which, as their name suggests, are used either for suction or for irrigation. In order to save the surgeon having to replace the suction tube with the irrigation cannula - and vice versa - an irrigation and suction device has been proposed which allows both processes to be carried out through one tube. This "rinsing and suction device, especially for treating the ears" from KELLEB (SD? No. 1 1o1 7o2) has other disadvantages. The Y-shaped confluence of the irrigation and suction line in the head part of the device leads to the attachment of bone chips, tissue particles, etc., and thus to the relocation of the two small tubes. The frequent clogging, especially the suction line obstructed and delayed the implementation of the operation loading iteänln t T i r> Tn KiiRaipAaxn cröa + o + + on ß.zsv "ä ö + A-ia.aa · * 'A * * * + ufi «N you

A further disadvantage is the simple connection between the cone of the mouthpiece and the inner cone of the height, which does not allow the tubes to be inserted in a position that is desirable for the surgeon and which corresponds to the particular surgical situation The shut-off mechanism for the flushing and suction lines also proves to be disadvantageous, since it requires constant quality and dimensions of the rubber hoses used, correct sealing of the lines does not guarantee and the hoses shear off after a short period of use.

The claimed invention has for its object to give the surgeon a rinsing and suction device at hand, which in technical design as simple as possible throughout the ear surgery, ranging from Warzenfortsatzausräuinung to Stapesoperation.bei neurochirur _ö lsehen operations and procedures in the field of the paranasal sinuses can be used universally, allows correct, alternate blocking of the suction and irrigation lines despite a simple shut-off mechanism, a large-caliber suction line guarantees trouble-free operation, and easy-to-use, easy-to-care handling for the surgeon thanks to screw-on, easy-to-care-for attachment tubes layout

is practical and handy.

The "universal suction and irrigation device, preferably for operations on the ear" consists of a base plate (8) movable cover plate (7), which by means of two screws (9). in the anterior-lateral angled ungea of both plates are connected. Both plates (7, 8) are also angled at their rear and designed for Abspsrrniechanismus, the tension of the spring (1o) between the plates being substantial. The front part of the base plate (8) is one Angled end wall to which the suction pipe (5) is attached. This structure means that simplicity is required and low economic outlay with the greatest possible efficiency.

The suction tube (5) is straight and large-caliber and the flushing tube (6) is fed in at the rear Part on the side, so that clogging of the line as a malfunction of the function is excluded. The front part the suction tube (5) was through an ion cone and an external thread Developed to accommodate various types of extension tubes (1). This gives the suction and flushing device the finest Extension tubes (1), e.g. B. with an outside diameter of 0.5 mm, as may be required in stapes operations, however also large-caliber extension tubes (1), e.g. B. up to an inner diameter of 4 mm and thus up to the inner dimension of the suction pipe (5) as used in neurosurgical operations and in mastoid processes. clearances are appropriate, attachable.

In this way a real universal usability of this device was achieved. The rear part of the suction and rinsing pipe (5, 6) ends in an olive and thus serves to attach the suction hose (11) and the rinsing hose (12). Both rubber hoses (11, 12) are passed through the rear parts of the base and cover plate (8 _T 7), which are angled towards the AbspBrrmechanismen and referred to as clamping pieces. Due to the tension of the spring (1o) between the two plates (7, P ^) in the rest or suction position (see Figure 3), the rinsing hose (12) located between the clamping pieces of both plates is squeezed off and the one under the clamping piece of the cover plate (7) The suction hose (11) is open and therefore fully functional when the vacuum pump is connected.

The inner cone and the outer thread on the front part of the suction tube (5) are used to attach attachment tubes (1) of different shape and dimensions, the connection through the cone (2) of the attachment tube (1) being possible and the fixing of the- ■ 'The same is ensured on the suction pipe (5) by the union nut (4). The union nut is well secured to the cone (2) by the spring ring O).

The syringe comes with the cone inserted into the bore and flushed the approach pipe (1) and cleaned in this way. This also makes the problem of maintaining the device, especially the fine approaches, favorable solved.

The grip and thus the safe handling of the universal suction and flushing device is due to a special design of the
