A medical instrumentarium for implanting a hip joint endoprosthesis, which instrumentarium comprises at least one sawing template with at least one guide slot for a saw blade, wherein:
- the sawing template comprises at least one first coupling element for temporarily coupling the sawing template to a second coupling element of a rasp body of a prosthesis rasp in a coupling position,
- the sawing template comprises a coupling body and a template body,
- the at least one first coupling element is arranged or formed on the coupling body,
- the at least one guide slot is arranged or formed on the template body,
- the medical instrumentarium further comprises a coupling device for temporarily coupling the coupling body and the template body in a coupling position, and
- the coupling device is configured in the form of a latching or snapping connecting device and comprises latching or snapping elements which are in engagement with each other in the coupling position.
A medical instrumentarium for implanting a hip joint endoprosthesis, which instrumentarium comprises at least one sawing template with at least one guide slot for a saw blade, wherein the sawing template comprises at least one first coupling element for temporarily coupling the sawing template to a second coupling element of a rasp body of a prosthesis rasp in a coupling position, wherein:
- the sawing template comprises a coupling body and a template body,
- the at least one first coupling element is arranged or formed on the coupling body,
- the at least one guide slot is arranged or formed on the template body,
