Definitions
- the invention relates to a resectoscope referred to in the preamble of claim 1 Art.
- Resectoscopes are surgical instruments that are used to remove tissue in the body. They are designed in endoscopic design with elongated shaft and allow observation of the surgical field with an optic and associated lighting. Resectoscopes include a carriage that is manually longitudinally displaceable and that moves a resection instrument, such as a high frequency pulsed loop electrode or a distal end emitting laser fiber. Resectoscopes are used, for example, in urology for the reduction of the prostate.
- a generic resectoscope is shown in DE 196 18 399 A1.
- the laser fiber is secured in the receiving bore of the carriage with a clamping button by clamping on the carriage. This ensures precise control of the laser fiber from the carriage.
- a disadvantage of this known construction is the punctiform attack of the clamping knob on the mechanically very sensitive laser fiber. This results in the possibility of unsafe clamping or damage to the laser fiber.
- Resectoscopes with a longitudinally displaceably mounted laser fiber are known from the publications DE 198 26 31 1 A1 and DE 20 201 1 051 869 U1. Furthermore, the documents WO 2008/133707 A1 and DE 10 2004 007 120 B3 describe possibilities for jamming laser fibers on medical instruments.
- the object of the present invention is to improve the clamping device in a generic resectoscope. This object is achieved with the features of the characterizing part of claim 1.
- a clamping body is mounted on the carriage, in which a moving area of the receiving bore is arranged. Other areas of the receiving bore, however, are arranged fixed in the carriage.
- the laser fiber thus successively passes through at least one region of the receiving bore fixed to the slide and a region of the receiving bore moved with the clamping body.
- the areas of the receiving bore are shifted from each other and this leads to a jamming of the laser fiber. Since the laser fiber is acted upon over a large area by the walls of the receiving bore, resulting in secure clamping only low loads for the sensitive laser fiber.
- the kinematics according to claim 2 is used, in which the moving region of the receiving bore is moved eccentrically rotating relative to its fixed region. This results in a very precise controllability of the clamping forces, especially when the eccentricity obeys the conditions of claim 3.
- FIG. 1 shows a side view of a resectoscope according to the invention with a slide
- FIG. 2 shows an enlarged detail view of the carriage from FIG. 1,
- FIG. 4 shows a section along line 4 - 4 in FIG. 3,
- FIG. 5 is a section corresponding to FIG. 4, but with the clamping body rotated and
- Figure 6 is a representation corresponding to Figure 4 in a variant.
- Figure 1 shows a resectoscope 1 with a shaft tube 2 which is fixed to a main body 2a. This is connected via an optical guide tube 3 with a guide plate 4.
- An elongate optic 5 with an eyepiece 5 a arranged at the proximal end passes through the guide tube 3 and the shaft tube 2 and is arranged such that the surgical area can be observed in front of the distal end of the shaft tube 2.
- a lighting device for illuminating the operating area is not shown to simplify the drawing.
- a carriage 6 is mounted with a guide bore 7 on the guide tube 3 longitudinally displaceable between the main body 2a and the guide plate 4. It is, as shown in FIGS. 1 and 2, passed through by a laser fiber 8 which, with the slight offset shown in FIG. 1, passes through the shaft tube 2 up to its distal end in order to be able to radiate a beam of force 9 there.
- the carriage 6 carries a finger grip 10 and the guide plate 4 a finger grip 1 1.
- the carriage 6 By operating these two finger grip pieces 10 and 11 with the fingers of one hand, the carriage 6 against the force of a spring 12, the slide 6 in Sliding direction relative to the guide plate 4 is supported, to be moved.
- the laser fiber 8 is to be moved in the longitudinal direction of the endoscope 1, that is to say in the direction of the optic 5 or of the shaft tube 2.
- a mechanical attachment between the laser fiber 8 and carriage 6 is required.
- FIGS. 2 to 4 show sectional views of the attachment of the laser fiber 8 to the carriage 6.
- a cylindrical cavity 13 is formed, whose axis is extended in the longitudinal direction, ie parallel to the guide bore 7.
- the cavity 13 is laterally accessible through a slot 14.
- the laser fiber 8 passes through the cylindrical cavity 13 and two holes 15 and 16 in the carriage 6, which are arranged distally or proximally from the cavity 13 to each other in alignment and in the longitudinal direction, ie parallel to the guide hole 7.
- the axis of the cylindrical cavity 13 is arranged concentrically to the bores 15 and 16, of which the bore 16 is shown in dashed lines in Figure 3.
- the clamping body 17 is traversed by a parallel to the bores 15 and 16, but eccentrically to these arranged bore 18, in which the laser fiber 8 extends.
- the clamping body 17 is rotatably mounted about the axis of the cavity 13 in this, as the figure 3 shows. This storage takes place with its peripheral surfaces. However, as shown in FIG. 3, the clamping body 17 is flattened on two parallel sides, these parallel sides lying at a distance corresponding to the width of the slot 14.
- Figure 3 shows the clamping body 17 in dashed lines in a rotated position by 90 degrees, in which it fits through the slot 14. If it is pushed into the region of the cavity 13 in the direction of the arrow 19, then it can be rotated in the cavity 13 about its axis in the position shown in solid lines in Figure 3. For turning, a laterally projecting actuating lever 20 can be attacked from the outside.
- the clamping body 17 has in its otherwise cylindrical outer surface a groove 21.
- FIG. 3 shows that the region 18 of the bore 15, 18, 16 passing through the carriage 6 is eccentric to the fixed areas 15, 16 of the bore.
- rotational position of the clamping body 17 with downwardly facing lever 20, the bore 18 relative to the bores 15 and 16 is displaced eccentrically. This rotational position is shown in FIG. If the clamping member 17 is rotated by 90 degrees in the rotational position shown in dashed lines, so are all three holes 15, 16 and 18 in alignment, as shown in Figure 5. It can be seen in the position of Figure 5, the laser fiber 8 is pushed freely by the carriage 6, so in particular inserted during assembly and placed in their desired position.
- the clamping body 17 is rotated from the rotational position of Figure 5 in the Figure 4, it can be seen that the laser fiber is clamped by the eccentric displacement of the holes. It is important to ensure that the eccentricity is smaller than the diameter of the holes 15, 16 and 18, otherwise no free passage would remain. Of course, the eccentricity must also be adapted in particular to the diameter of the laser fiber, ie approximately as shown in FIG. 4. Then in the position of Figure 4 a slight, not damaging clamping is achieved.
- FIG. 6 shows in a representation according to FIG. 4 a variant in which the clamping body 17 'in the direction of the laser fiber 8 is slightly shorter than the cavity 13. Between the ends of the moving bore 18 and the inner ends of the holes 15 and 16 fixed relative to the slide 6 So there is one distance each. As apparent from Figure 6, this results in a reduced shear between these bore ends and thus a reduced risk of damage.
