Description

SURGICAL INSTRUMENT PIPE SHAFT

The invention relates to a surgical Rohrschaftin¬ instrument having a tube, at the end of a holder for a tool is detachably held, and arranged with a in the pipe and in that longitudinally movable Betätigungsele¬ element for moving the tool, with an electrical insulation of the tube and the holder.

Such surgical tubular-shafted instrument is spielsweise be¬ known from the German utility model 9,318,815th In order to electrically isolate such a tube shaft instrument at the Außensei¬ te, it is provided here that the holder at the outer side is covered with a specific electrically insulating layer, also adjoins the holder, an insulating outer sheath, which surrounds the tube of the tubular shaft instrument and the tube defining a fixing position in which the pipe is connected axially fixed with the holder of the tools. In order to achieve a proper electrical insulation in the region of the holder here in each case is a special electrical insulating layer on this Halte¬ tion needed, and this requires complicated Herstel¬ development steps, since it must also be ensured in the production, that said layer really all parts of the Hal¬ esterification covered and keeping a low profile strumentes during the lifetime of the Rohrschaftin¬.

It is an object of the invention is to design a generic chirurgi¬ ULTRASONIC tubular shaft instrument, in that the elektri¬ specific isolation can be achieved properly in the holding area with einfa¬ Cheren means.

This object is achieved with a surgical instrument Rohrschaftin¬ the type described above according to the invention da¬ solved by that the holder is composed entirely of a elek¬ cally insulating material.

It is thus not used, a metal support in a conventional manner, which is coated on the outside electrically insulating, but it is made outgoing from the outset, the holder of an electrically insulating material from this be¬ known art.

This electrically insulating material may be, for example, plastic, particularly advantageous, however, is when the bracket is made of ceramic.

In a preferred embodiment, with an insertable into the tubular extension of the mount, the radial recesses, into which radially displaceable Vor¬ cracks of the tube engage and thereby fix the holder axially, can be provided according to a further, that the radial projections extend only over extending part of the circumference of the extension and dazwi¬ rule parallel to the longitudinal axis of the extension stop extending webs which connect the protruding out of the tube part of the holder with its extension.

When using electrically insulating materials, in particular ceramics, stability problems can da¬ by revealed that these materials have lower strengths than conventional metallic materials. Especially ceramic is compared with relatively little tensile wider¬ was capable, and therefore there is the danger that in the region of the recesses formed in the prior art as a circumferential annular groove and thus form notches Be¬ occur damage. This danger is represented by the Unter¬ the radial recesses in the circumferential direction refraction unter¬ connected forming ge between the recesses are permanent Ste¬ a reinforcement, which bridge this weakened area and, therefore, the necessary strength len sicherstel¬.

A particularly advantageous embodiment results when the extension in the area of ​​the recesses is tapered stepwise at their inserted into the tube end and when the webs as a continuation of the portion of Ver¬ prolongation of larger outer diameter in the part with ge lesser outer diameter extending , Thereby, an optimum gain, so that even at the lower strength values ​​of the electrically insulating materials, so in particular ceramic, a aus¬ reaching stability can be achieved overall. Arises in the transition region in which the radial recesses are arranged ange¬

The following description of preferred embodiments of the invention serves in conjunction with the drawings for a more detailed explanation. Show it:

1 shows a schematic side view of a

Tube shaft instrument with a tongs-like movable tools;

Figure 2 is a partial perspective view of the tubular-shaft instrument of Figure 1 in the connection area between the holder of the tool and the pipe stem and

Figure 3 is a longitudinal sectional view in Verbindungs¬ region of the tool holder and of the tubular shaft along line 3-3 in FIG. 2

The tubular-shaft instrument 1 illustrated in the drawings comprises a tubular shank 2, in the front end of a holder 3 is fitted, are pivotally supported on the two jaw-like tools 4, 5 about a common axis, thus forming a gripping instrument or a forceps. The movement of the two tools 4 and 5 is carried out by ei¬ ne arranged in the interior of the shaft 2 pushing and tensile rod 6 occurs and at the rear end of the shank 2 there hervor¬ hingedly connected to a handle part 7 is, in turn, is rotatably mounted on a second gripping arm. 8 This second gripping arm 8 is rigidly connected to the shaft 2 so that 7 and 8 against each other, the back thrust and Zugstan¬ ge 6 in the interior of the shaft during the pivoting of the two gripping arms and is pushed in.

The bracket 3 shown in greater detail in Figures 2 and 3 has a front circular-cylindrical portion 9 with ei¬ nem axially parallel, forwardly open compartment 10, in which the two tools 4 and 5 engage. In this area, the tools are pivotally supported by a support shaft 11 querverlau¬ Fende 4 and 5. FIG. By reaching from the rear end up in the tray 10 Durchgangs¬ opening 12, the push and pull rod 6 extends into the compartment 10 into and gear means not shown here nä¬ there is with in the drawing connected to the pivoting of a comparison of the tools 4 cause the bearing shaft. 11

At the front portion 9 of the holder 3, a middle portion includes at 13 to an annular step 14 is set back from the front portion, and thus has a smaller outside diameter than the front portion. On which the annular step 14 the opposite end of this central portion 13 goes via a further step 17 in a rear section 15 via whose Außendurch¬ knife is again smaller than that of the middle section 13. Ab¬ to the annular step 17 is immediately adjacent an annular groove 16 in the outer periphery at the rear portion 15 through which the rear portion 15 is further weakened in the immediate connection to the middle section. 13 This annular groove 16 forms a radial recess in this area. However, the annular groove 16 does not extend over the gesam¬ th outer periphery of the rear portion 15, but it is interrupted by webs 18 which axially extend as a continuation of the central portion 13 via the annular groove 16 of time and in turn in the form of a step 19 in the pass lateral surface of the rear portion 15th These webs 18, which may be, for example, staggered by 90 ° and each extending over a Win¬ angle range of, for example 20 ° in order to bridge the annular groove 16 and strengthen the bracket in Über¬ transition region from the central portion 13 in the rear Ab¬ section 15. the weakening effect of the annular groove 16 da¬ is canceled at least partially.

The entire holder 3 is integrally formed and be¬ is made of an electrically insulating material, preferred wise from ceramic.

When assembled, the rear portion 15 of the holder 3 is immersed in the tubular shaft 2 and rests against the inner wall thereof. The shaft 2 carries at its end a plurality of resilient tongues vorde¬ ren 20 te by Längsschnit¬ 21 are separated from each other and bear the inwardly hervor¬ passing, radial projections 22nd The longitudinal sections 21 extend towards the front end stepped and form forwardly open pockets 23, into which the webs 18 cut in the transition area between the middle Ab¬ 13 and the rear portion 15 of the holder 3 occur. When the rear portion 15 is completely inserted into the shaft 2, 22 immerse the projections into the annular groove 16, and in this position the tongues are fixed 20 by a tubular sleeve 24 which slidably on the rohr¬ shaped shaft 2 in the axial direction gela¬ is Gert and includes the tubular shaft 2 and with die¬ sem in the central portion 13 aligned holder 3 tightly when they are located in the forward position (Figure 3), in which the sleeve 24 abuts against the annular step 14 , The sleeve 24 is made of electrically insulating material, so that in the transition region the group consisting of electrically insulating material sleeve of a hand, and the total consisting of electrically insulating material holder 3 on the other hand, no electrical connection is possible to the outside.
