This invention concerns a device for sucking up and collecting bone particles, such as bone meal, and bore chips from cooling and/or rinsing liquids during dental interventions in implantology and in the field of bone regeneration periodontology. Said device essentially consists of an aspirator tip (1), an adapter (7), and a housing with an upper part (2), a lower part (4) and a filter sieve (3). A conical intake port (2b) leads past a sharp-edged transition section (2c) into a dome-shaped cavity (2d) in the upper part (2). A funnel-shaped cavity (4b) in the lower part (4) adjoins it. Between the cavities (2d; 4b), a filter sieve (3) is located. The upper part (2) is provided with a collar (2a) into which an O-ring (5) fits. The lower part (4) is provided with a recess with a wall (4a) and with a connecting port (4c) for a hose (6). The collar (2a), the O-ring (5) and the wall (4a) form the housing closure in which the filter sieve (3) is seated. The upper part (2) and the lower part (4) are made of pure titanium. The filter sieves(3) are graded in degree of fineness and soldered through the rim. The adapter (7) is provided with different inlet ports for different aspirator tips.

Description

Title of invention

A device for suction and collection of bone particles

technical field

The invention relates to a device for sucking and collecting of bone such as bone meal and drill cuttings from the cooling or rinsing liquid at zahnärtzlichen Arbei- th in implantology, and in the field of bone regeneration in periodontology.

State of the art

Devices for sucking and collecting of bone such as bone meal and bone chips are well known. As is known from DE GM 26 295 147 a device for the suction of bone and metal chips in dental work known which consists of a suction pipe and a filter housing with a suction hose. In the housing a filter for collecting the bone chips and a check valve are arranged. Between these an adjustable throttle valve is provided. Inside the housing a movable piston for emptying of the collected output chips is further arranged reasonable.

This device is very expensive. With their use sterility and purity problems. Thus, the entire device must be thoroughly cleaned and sterilized after each use. It is not suitable for catching the smallest bone particles. Furthermore, 86 09 630, a device for collecting debris from the rinsing water in operations on the bony skeleton, in particular at the head known from DE GM, a bone meal filter is disposed in the housing. The housing con- sists of two interconnected cylindrical halves and is provided with two connection sockets which are connected to an axis extending parallel to the discharge pipe switchable bypass line. The bone filter is designed as a reinforced net and removable from the housing bar. It consists of a polymeric material and has variable pore sizes.

A disadvantage of this device is the non-uniform deposition of the collected bone particles in the filter, whereby an uneven flushing occurs. In addition, the uneven layer complicates the further processing.

a "bone all" MED, 47441 Moers, known This device consists of a functioning as a handle aluminum housing with a suction hose The housing is pe with a Verschlußkap- provided with surgical aspirator - also is from a brochure of the company S & W DENTAL... inside the housing a collecting filter (filter cartridge) is arranged for autologous bone material. the filter consists of a sterilizable plastic and is used for multiple use. This device is encumbered with some disadvantages. Thus, easy corrosion particles of the aluminum case can engage with the augmentation material into the surgical area. in addition, there is the problem of multiple use of a plastic sieve (cleaning virtually impossible). Furthermore prepare edges and grooves as well as the hard to reach interior seal-problems in cleaning.

Summary of the Invention

The invention has for its object to eliminate the drawbacks of the prior art and to provide a further device for sucking and collecting of bone such as bone meal and bone chips, which allows a uniform precipitation of the filtrate on the screen surface of the filter.

According to the invention an inlet port is held via conically at a sharp-edged transition in a dome-shaped cavity of the upper part. This is followed by a funnel-ger cavity of the lower part connects. Between the cavities, a filter screen is arranged. The upper part is provided with an O-ring receiving collar. The lower part is provided with a recess with a wall and with a connection piece for a hose. The collar, the O-ring and the wall forming the casing closure in which the filter screen is locked. The upper part and the lower part are made of pure titanium. The filter screens are graduated in fineness. The filter is welded to an edge. The suction cannula is mounted in an adapter of the upper part, which is provided with different inlet ports.

Brief Description of Drawing

In the accompanying drawing the solution according to the invention is shown in section.

BEST MODE FOR CARRYING OUT THE INVENTION

The invention consists essentially of a suction cannula 1, an adapter 7, a housing with an upper part 2, the lower part 4 and a filter 3. The upper part 2 is a rotationally symmetric turned part with a collar 2a with an annular groove for an O-ring 5 is provided. A slightly conical inlet opening 2b via a sharp-edged transition 2c in a dome-like cavity 2d, which is delimited by the funnel-shaped cavity 4b of the likewise rotationally symmetrical bottom part 4 by means of a filter. 3 The filter 3 is made of a sterilizable plastics material and is welded to a reinforcing rim. It can filter screens 3 with different pore openings, so different fineness are used, for example those having pore openings of 100 - 300 microns. Because of the high demands on sterility and purity filter screens 3 are used as disposables used.

The lower part 4 is provided with a recess whereby the wall 4a 4d a plant for the filter 3 is. The cavity 4b opens into a connection piece 4c for a hose 6 of a treatment unit unspecified with suction.

Upper part 2 and lower part 4 are connected to each other by the wall 4a is pushed over the collar 2a, and thus the O-ring 5 is compressed. In this case, the filter 3 is locked by the front side of the collar 2a and the plant in an annular groove 4d. These elements constitute the cap of the manufactured made of high resistant pure titanium housing of the device. According to its varied uses a preferably consisting of plastic adapter is received with his see also conical projection 7 in the inlet opening 2b. The adapter 7 is provided with different size bores for accommodating all known cannulae. 1 These can be made of metal or plastic. All components of the device can be sterilized. It is ergonomically advantageous designed as a handle.

The operation of the apparatus of the invention is the following:

The device is connected to an unillustrated treatment device with suction. Bone meal or bone chips are produced in the treatment area through the use of medical devices with material-removing effect, such as sawing, milling, drilling, etc., for example, in dental implantology, for example, after cavity preparation for implants or targeted removal of bone for the augmentation and in the field of bone regeneration in periodontology. The aim is always a priority augmentation with auto- LOGEM material. The suction cannula 1 is for this purpose placed in the OP area, so that the bone material found in a cooling or flushing liquid (bone meal, bone chips) sucked in the conical inlet opening 2b passes and is swirled fluidically in the dome-shaped cavity 2d at the sharp-edged transition 2c. These technical measures result in that the filtrate is distributed evenly on the sieve surface about 3 cm 2 is collected. The removal of autologous material -about 3 cm 3 - is then easy. To do this, open the case and are the filter 3 including augmentation in a prepared sterile dish. After insertion of a new sterile filter screen 3, the apparatus is operational again. It is justified by its construction the requirements for sterility and purity. Its light weight and ergonomic design allow for easy handling. Due to the small number of components it is inexpensive to produce.

commercial Applications

The invention is ontology in dental work in the implant and used commercially in conjunction with other medical devices in the field of bone regeneration in periodontology.
