Abstract
A holding apparatus is provided for a trocar sleeve suitable for fixing the trocar sleeve in different positions relative to the patient. The holding apparatus comprises a base member fixedly positionable with respect to the patient and a retainer for the trocar sleeve. The retainer is connected to be tiltable with respect to the base member by a flexible connecting member. According to the invention, the connecting member has a first flexible operational state and a second rigid operational state and the connecting member can be switched between the first flexible and the second rigid operational state.
Claims22
An apparatus for holding a trocar sleeve in different spatial orientations relative to a patient, comprising:
- a base member which can be positioned and fixed relative to the patient,
- a retainer for receiving and holding a trocar sleeve inserted into said body of said patient, and
- a connecting member for connecting said base member to said retainer, wherein said connecting member has a first operational state in which it is flexible, allowing said retainer to tilt with respect to said base member, and has a second operational state in which it is rigid, and
- wherein said connecting member comprises an elastic casing filled with a material being variable in rigidity.
An apparatus for holding a trocar sleeve in different spatial orientations relative to a patient, comprising:
- a base member which can be positioned and fixed relative to the patient,
- a retainer for receiving and holding a trocar sleeve inserted into said body of said patient, and
- a connecting member for connecting said base member to said retainer, wherein said connecting member has a first operational state in which it is flexible, allowing said retainer to tilt with respect to said base member, and has a second operational state in which it is rigid, and
- wherein said connecting member comprises a material which is flexible at an adjustable first operational temperature in said first operational state of said connecting member and is rigid at a second operational temperature in said second operational state.
An apparatus for holding a trocar sleeve in different spatial orientations relative to a patient, comprising:
- a base member which can be positioned and fixed relative to the patient,
- a retainer for receiving and holding a trocar sleeve inserted into said body of said patient, and
- a connecting member for connecting said base member to said retainer, wherein said connecting member has a first operational state in which it is flexible, allowing said retainer to tilt with respect to said base member, and has a second operational state in which it is rigid, and
- wherein said connecting member is a torus-shaped body having a central opening, said retainer being arranged in said opening.
