Abstract

The invention relates to a rotating dental surgical instrument, comprising a base body (1) which has a clamp-end (2) that can be connected to an angled piece (3) and a working area (4) which tapers into a cutting area (5), whereby the working area (4) has at least one grooved removal channel on its external surface and is provided with cutting edges (9, 10) consisting of a resistant material on the free end of the cutting area, which lie transversely to the shaft axis (7).

Description

Description: Chilled rotating dental surgical instrument

description

In the field of dental surgery drill similar rotary instruments are needed particularly for the preparation of the jaw bone for a recording of implants.

So far, these instruments are made of stainless steel, and its shank is provided over its entire length with a coolant channel, such as a physiological saline solution can be supplied through the in the field of exciting a coolant that may leak in the cutting area through an exit opening at the other end and this provides the necessary cooling of the jaw bone at the surgical site. the coolant is swept along with the ausgebohr- th bone material outwardly through a corresponding channel-shaped discharge channel on the outer surface of the instrument.

For a shaft diameter of only 2.35 mm, the manufacture of such thin drill similar instruments is very costly and, accordingly, such tools are expensive. leave while the bone of a human upper jaw is still relatively soft, the bone of a human mandible has a much higher hardness, so that the previously known auger instruments of stainless steel have only a very short service life and therefore the surgical treatment instrument- other costly to ,

The invention has for its object to provide a dental instrument of the aforementioned kind, which has a longer service life.

BESTATIGUNGSKOPIE This object is achieved by a rotating dental instrument having a base body, having a connectible with an elbow Exciting and terminating in a cutting area of ​​the work area, the work area having a groove-shaped discharge channel on its outer surface at least at the free end of the cutting portion transversely to the base body axis hosted cutting edges are provided of a hard material. The instrument according to the invention can be complete, for example, made of a hard material a hard metal. However, it is advantageous if, as usual, the main body of a corrosion resistant steel is manufactured and consist of only the cutting edges of a hard material, in particular a hard metal, so that compared with the previously known, after the cutting-edge region mono- instruments made entirely of corrosion-resistant steel, a significantly longer service life results.

In a preferred embodiment of the invention Provision is made for that the cutting region by a cutting body

Hard material is formed, which is held in a delimited by two jaws slot on the base body. This arrangement has the advantage that the cutting body made of a hard material such as a carbide can be formed as a compact body with high structural strength, on the other hand, when the come into consideration small diameters, for example, only 2.35 mm, the base body including the operating range stainless steel and consists of a tough material. This ensures that a break of the base Körperes can be virtually eliminated and at a fraction of the more brittle hard material during preparation only Bruchstük- ke the hard material arise, which are flooded with the pushed-bone material from the cooling liquid herausge-. In one embodiment of the invention it is provided that a extending in the longitudinal direction and provided with at least one outlet opening in the vicinity of the cutting region coolant channel is arranged in the base body. By this coolant channel, a physiological saline solution for cooling can, as already indicated, be inserted, which exits in the engagement region of the instrument and through which the drilled bone material is flushed through the nutförmi- gen transportation channel.

It is particularly advantageous if at least one outlet opening of the coolant channel is disposed on an end face of a jaw adjacent to the cutting body. This offers the advantage that the coolant outlet where the highest thermal load on the bone material is produced by the drilling operation. It is expedient if both cheeks are each provided with an outlet opening, which are connected to the centrally extending coolant channel in each case via a branch channel with a correspondingly lower diameter.

The invention will be explained in more detail with reference to schematic drawings of an embodiment. Show it:

Fig. 1 is a side view of a dental surgical instrument,

Fig. 2 in larger scale, a plan view of the

Cutting range of the instrument gem. Fig. 1

Fig. 3 shows another embodiment of the cutting-edge region.

The illustrated in Fig. 1 rotating dental surgical instrument comprises a rod-shaped main body 1 having a circular cross-section which is made of a corrosion-resistant steel. The base body 1 is provided at one end with a Exciting 2, by which the instrument can be fixed in an angle handpiece 3 via which the drive is of the instrument and also a coolant supply, as will be described in more detail below.

At the exciting 2, a work area 4 connects, which terminates in a cutting region. 5 The working area 4 of the base body 1 is provided on its outer surface with at least one, here two groove-shaped discharge channels. 6

The cutting region 5 is, in the illustrated exemplary example, by a transversely oriented to the axis 7 of the base 1 cutting body 8 formed which is made of a hard metal or a hard material usable correspondingly for cutting purposes. In the illustrated embodiment, the cutting element 8 is so reasonable ground that two side cutting edges 9 are provided. The side cutting edges 9 associated end faces 9.1 roof-shaped run together in the area of ​​the basic body axis 7, and are sharpened to form a clearance face for each of the corresponding side cutting edge. 9

The two side cutting edges 9 are in the region of the tip of the blade body 8 via a main cutting edge 10 (see FIG. FIG. 2) connected to each other. The cutting edge of the main cutting edge 10 practically determines the life of the instrument.

The base body 1 is provided with an extending over its entire length coolant channel 11, which communicates in the area of ​​the exciting 2 with a not-shown coolant inflow angle handpiece. 3 In the illustrated embodiment, the coolant channel 11 branches in the vicinity of the cutting portion 5 in the material of the base body 1 in two sub-channels 11.1 and 11.2 which open in each one Austrittsöff ung 12.1 and 12.2.

Since, as shown in Fig. 2, the base body 1 in the cutting area has a limited by two jaws 13 slot 14 in which the cutting element 8 is fixed from hard material, the two sub-channels may 11.1 and 11.2, with their outlet openings 12.1 and 12.2 respectively in a of the end faces 15 of the jaws 13 are fed out, so that the existing cutting of hard material body is not weakened in its cross section. 8 This is illustrated in Fig. 2 as a plan view in larger scale on the tip of the cutting portion 5. Alternatively, it is also possible to provide a transverse bore even in the material of the base body 1 at a small distance for cutting body 8 constituting 11 intersect det and corresponding, opening out near the cutting portion 5 sub-channels the coolant passage.

The invention is not limited to instruments where Exciting and workspace aufwei- the same diameter sen. It is also possible, depending on the requirements to provide a comparison with the diameter of the exciting larger or smaller diameter for the workspace. 4

Instead of the illustrated arrangement of two helically extending groove-shaped discharge channels 6, other forms of design for the work area 4 are possible. For example, the working area 4 may be formed in the manner of a so-called gun drill, ie, be provided over the length of the working area with little minutely an axially extending groove.

The use of a separate cutting body made of carbide allows other shapes for Schneidengeome- trie. The cutting assembly can be formed simply stepped or, as shown in Fig. 3 in a side view as an example schematically, multiple graded be formed, ie, next to the main cutting edge 10 with their side cutting edges 9 also axially set back towards the main cutting edge 10 additional cutting acting 10.1 and provided 10.2, is formed so that the profile of the borehole to create graded and correspondingly shaped implants in the jaw to be treated can be used.
