Abstract

The invention relates to a surgical instrument system encompassing a morcellator with a hollow shaft on whose distal end a cutting blade is configured, as well as a gripping instrument with a shaft on whose distal end a tool consisting of at least two jaw members and on whose proximal end a handle consisting of at least two gripping members is configured to activate the tool, in such a way that the gripping instrument can be inserted into the hollow shaft of the morcellator so that it can slide in the longitudinal direction of the morcellator shaft. To ensure versatile application along with simple structure, it is proposed with the invention that the morcellator with the insertable gripping instrument can be inserted into a hollow shaft of an additional medical instrument, in particular a resectoscope, and that an additional irrigation and/or suction canal is configured between the shaft of the morcellator and the inside of the hollow shaft of the additional medical instrument.

First claim

What is claimed is:

1. A surgical instrument system comprising: a morcellator with a hollow shaft on whose distal end a cutting blade is configured,
a gripping instrument with a shaft on whose distal end a tool is configured that comprises at least two jaw members and on whose proximal end a handle is configured that comprises at least two gripping members for activating the tool, wherein the gripping instrument is insertable into the hollow shaft of the morcellator by sliding it in a longitudinal direction of the hollow shaft of the morcellator,
and an additional medical instrument, wherein the morcellator with the gripping instrument can be inserted into a hollow shaft of the additional medical instrument and in that at least one irrigation and/or suction canal is arranged within the hollow shaft of the morcellator and an additional irrigation and/or suction canal extends between an outer surface of the hollow shaft of the morcellator and an inner surface of the hollow shaft of the additional medical instrument such that the additional irrigation and/or suction canal is annular and is formed by the outer surface of the hollow shaft of the morcellator and the inner surface of the hollow shaft of the additional medical instrument, wherein a distal end of the hollow shaft of the additional medical instrument is arched inward about its complete circumference to configure the additional irrigation and/or suction canal.

2. The surgical instrument system according to claim 1 , distinguished in that the additional irrigation and/or suction canal is insulated on a proximal side by an insulation from a inside of the hollow shaft of the additional medical instrument.

3. The surgical instrument system according to claim 1 , distinguished in that the gripping instrument is outfitted additionally with an optical observation unit as well as at least one irrigation and/or suction canal, in such a way that the at least one irrigation and/or suction canal is positioned inside the optical observation unit.

4. The surgical instrument system according to claim 1 , distinguished in that a cutting blade guard is configured on the gripping instrument and upon insertion of the morcellator into an operating area, the cutting blade guard can be brought into radially flush contact with the cutting blade of the morcellator and in the axial direction closes at least flush with the cutting blade.

5. The surgical instrument system according to claim 4 , distinguished in that the cutting blade guard is configured as a thickened area positioned at a distance from the tool on the shaft of the gripping instrument.

6. The surgical instrument system according to claim 1 , distinguished in that the gripping instrument is a gripping pincer equipped with two jaw members rotatable relative to one another.

7. The surgical instrument system according to claim 6 , distinguished in that the jaw members can be fixed in their position with respect to one another by means of a sickle-shaped notching rod positioned on one of the gripping members.

8. The surgical instrument system according to claim 7 , distinguished in that the jaw members can be fixed in pre-established angle positions with respect to one another.

9. The surgical instrument system according to claim 7 , distinguished in that the jaw members are fixed with respect to one another by means of the handle.

10. The surgical instrument system according to claim 7 , distinguished in that the jaw members are fixed with respect to one another by means of the jaw members.

11. The surgical instrument system according to claim 7 , distinguished in that the jaw members are fixed with respect to one another by means of a push-pull rod that connects the handle with the jaw members.

12. The surgical instrument system according to claim 6 , distinguished in that the angle of rotation of the jaw members with respect to one another upon pulling the gripping instrument into the hollow shaft of the morcellator can be restricted in such a way that the jaw members of the gripping instrument can be drawn into the shaft of the morcellator without making contact.

13. The surgical instrument system according to claim 1 , distinguished in that the hollow shaft of the morcellator can be insulated from the environment by means of a double insulation arrangement.

14. A The surgical instrument system according to claim 13 , distinguished in that one insulation of the double-insulation arrangement is configured as a ring insulation disc to insulate from the gripping instrument that can be inserted into the hollow shaft of the morcellator and the other insulation of the double insulation arrangement is configured as a cross-slit insulation, which insulates an inner lumen of the hollow shaft of the morcellator when the gripping instrument is withdrawn.

15. The surgical instrument system according to claim 1 , distinguished in that the additional medical instrument is a resectoscope.
