One such handpiece is known from West German Practical IBi'Hair No. 6940204)C. In the case of this known second piece, the photoconducting part 41 has water and air, and because of its power, it also receives an O review. Inside the complementary hose, run from the supply part provided at the end of this end piece opposite to the tool, along the outside of the end piece to the end of this hunt 2 piece on the Eva side. . In order to enable relative partial rotation between the end piece body and the supply section, the primary hose is assembled with some slack. Therefore, the hose running along the outside of the handpiece makes it very difficult to grip and hold the body of the huntpiece, and to treat the practitioner accordingly.

An embodiment of the above invention will be described below based on FIG.

The handpiece body 1 has inside thereof essentially a cylindrical drive l1) 12 over the entire length of the handpiece body, and this drive shaft 2#-i has a treatment mechanism J4J provided at one end of the handpiece body. For example, tii' is used to drive (rotate in the case shown) the perforator. In addition to this handpiece main body #i, a photoconductive member 4 is provided, one end 5 of which is located at the operator 3 is directed toward the treatment area of the operator 3, and the other end #i6 is opposite to the operator 3.
is directed toward the light source 7.

The drive 4112#i has a hollow space rkJ&, and the photoconductive member 4 is disposed in this hollow space 8.
12 to a ratio.

...In order to simply accommodate the photoconductive member 4 inside the handpiece body 1, the drive shaft 2 and the photoconductive member 4 are visible from the end of the handpiece body q/1 as shown in the figure. It is divided into 1 horizontal sections with a gap in between. and each portion 12.13 of the photoconductive member formed by this transverse division.
, it is preferable that the adjacent ends 10.11 be arranged in two opposite directions.The tool side portion 15F of the drive shaft
Three accommodated by J bearing 15'! ) 5' middle 1 (support plate is located).

The transverse division 1 of the drive shaft 2 is connected via a transmission gear 14, and the 'f5r
There is an eleventh point where the desired conduction ratio can be selected, for example >L = 1° or <1.

In the embodiments shown in FIGS. 3 and 7, the tool-side portion 5 of the drive shaft 2 is hollow, similar to the tool 3-side portion. The inside of the hollow drive shaft part 5 of the worker 3111I (the part on the X side of the photoconductive member 4) 2 is shown in white, t11. As can be seen, the tool-side end 9 of the tool-side portion 12 of this light-conducting member 4 is bent in the radial direction, and the end groove of this tool-side portion is directed toward the surrounding wall of the hollow drive shaft 2. A light transmitting part 17 made of glass, for example, is provided at this end slot, and a light guide groove J8 is formed at least one point above υ from which light can be projected to the treatment area i1. A relay light-conducting member 19 is arranged on the middle desk of No. 8, and as shown in FIG. Another light guide 5' is arranged.The tool, 1ltl end 9, is divided into a number of photoconductor parts, for example four, as is clear from FIG. In this case, each photoconductor section is bent in the radial direction, so that its end J6 is directed towards the light-transmitting part of the hollow drive shaft 2 and, depending on the case VC, touches this light-transmitting part J7. ing.

In the case of the embodiment shown in FIG. 3, the transmission J4 connecting the transverse divisions of the drive shaft 2 has a transmission ratio of 1:1, and this transmission J4 connects the transverse divisions V to The drive shaft part 15.21 engages with the 89 end 2
It is constructed by providing seven engaging receptacles 22. In this case, both of the two pedestals 22 are made of -F- ceramics of the same size.

Figure 7 is actually the same as Figure 3.
The handpiece body 1 has a curved shape (on the other hand, the handpiece body 1 has a straight shape as shown in Fig. 7), and the light is different.

In the case of the embodiment shown in Fig. 5, the tool part of the photoconductive post 4)
is the drive shaft (2'J) inside the handpiece body 1.
- A complete view of the side part No. 5, which is the second base part J of the original conducting part "shrine 4" as in the case of FIGS. 3 and 7.
2 is studying the inside of the hollow drive 1 #J width 12 part No. 5 as mentioned above. In the case of the 5th 1, the 5th part of the 1st part of the drive 2 may be solidly organized. To explain in detail, in the case of Figure 5,
In that configuration, the tool-side portion 12 of the light-conducting member 4 is initially directed radially or approximately radially outwardly from its end opposite the tool 3 and adjacent to the tool-side portion 15 of the drive shaft 2 . extends in the axial direction, with this tool side portion 12
One end 5 on the tool side extends from the handpiece body 1 toward the treatment area. It is preferred if the tool-side portion 12 of the light-conducting member 4 is divided into a number of conductor portions 23, which extend parallel or substantially parallel to each other. In the case of FIG. 6, the tool side section 12 mentioned above is divided into two conductor sections 23. In the case of FIG. As is further evident from FIGS. 5 and 6, the tool-side part 12 of the light-conducting part 4 has, at least at its tool-side end 9, a tool-side end 24 directed toward the treatment area of the tool 3. Also, this tool side end 9 extends parallel or parallel to one or more medium pipes 25, such as cooling medium pipes, disposed inside the end piece main body J. There is.

In one of the embodiments shown in FIG. 5, a transmission device 14 connects the transversal divisions of the drive shaft 2 [14] is a drive shaft portion 15 whose transmission ratio is greater than 1 and is formed by the above-mentioned transverse division. ．．
m fastening means, for example 26, at each adjacent end of 21.
．． 27, resulting in a total of 41+1. In the gap, the two retaining stages 26 and 27 are engaged with each other so that the tool side end 9 of the photoconductive member 4q) tool @ portion 12 is directed outward so that it can be assembled. It is constructed and one is placed. For this reason, the engagement means 26 on the tool side portion 15 of the drive shaft 2 is formed by a relatively small flat wheel, and the engagement means 27 on the portion 2 of the drive shaft 2 on the opposite side to the tool 3 is therefore It consists of a relatively large spur gear.

The fifth embodiment shows a very simple method of grinding from the drive shaft 2 of the original conduction part 4, but this direct engagement □! In the case of transmissions of the shoulder type, it is impossible or difficult to incorporate transmissions with a transmission ratio of 1 or less.

Engagement means 37° 3s; 39, 4o arranged so that two adjacent ends of the drive shaft portion 15.21 are indirectly engaged
The embodiment shown in FIG. 8 having . . . is clearly advantageous in many cases.

That is, in this case, the transmission device f14 can be configured as a variable transmission ratio type transmission device. in this case,
The variable transmission t14 can be exchanged externally and has two locking means (28, 29', 29', 30.31', 32.33) with engaging means 37.3.
