Abstract

The invention relates to a surgical procedures device in connection with a medical procedure, the device comprising an orientation arm (3) adapted to be used for performing and/or guiding the movements required by the procedure, and said orientation arm (3) being protected or protectable by means of a sterile or sterilizable protection means (11), and to which orientation arm (3) or equivalent means a surgical instrument (4), such as a needle, an ultrasonic probe or equivalent means is connected or connectable, and the orientation arm (3) being connected or connectable to the surgical instrument (4) by means of an intermediate piece (12) or equivalent, made of a sterilizable material. The intermediate piece (12) and orientation arm (3) comprise identification means (15, 16) for generating an identification signal specific to the surgical instrument and for permitting the identification of the surgical instrument (4).

Claims

1. A device for performing surgical procedures comprising:

orientation means for guiding movements to perform said surgical procedures;

a surgical instrument for performing a selected one of said surgical procedures;

an intermediate piece having two ends, said intermediate piece being engageable with the orientation means at one of said ends and connected to said surgical instrument at the other end;

means connected to the orientation means for generating at least one signal; and

identification means carried by the intermediate piece for causing the generating means to generate said at least one signal when said orientation means is engaged with said intermediate piece, said at least one signal identifying said surgical instrument;

whereby said at least one signal is read to ensure propriety of said surgical instrument to be used for the selected surgical procedure.

2. A device according to claim 1, wherein the identification means further comprises switch means disposed on a first surface on the orientation means, and contact means (16) disposed on a second surface on the intermediate piece for enabling said switch means when said orientation means is engaged with said intermediate piece.

3. A device according to claim 2, wherein at least the switch means is protected by sterilizable protection means.

4. A device according to claim 2, wherein said at least one signal comprises electrical signals, said .generating means including a plurality of electrical circuits, the switch means including switches for closing said electrical circuits when said switches are enabled, being shaped in such a way that a selected combination of said switches are enabled when said switch means is engaged with said contact means.

5. A device according to claim 2 or 4, wherein the orientation means further comprises a projection on an end thereof, said projection having said first surface.

6. A device according to claim 2, wherein the intermediate piece further comprises a frame member and an interchangeable contact member, said frame member engageable with the orientation means, said interchangeable contact member having said second surface and being engageable with said frame member, said contact means being associated with said surgical instrument, whereby when the frame member is engaged with the orientation means, the contact means selectively enables the switch means.
