Abstract
There is provided a surgical instrument that simplifies surgery for implantation surgery for treating anal incontinence in women. The disclosed surgical instrument is intended to be inserted through an incision in the vagina and is used for dissecting tissue as well as positioning the implant. The instrument comprises a main part of the instrument, an elongated member with a flexible tip and can change conformation from a straight conformation to a loop conformation that can reach around a portion of the rectum.
Claims32
A surgical instrument for accessing an opening in the vaginal wall of a patient, the
- instrument comprising:
- an elongated main part (21),
- an elongated member (23) attached to the elongated main part by means of a first joint (42) having a pivotal axis, wherein a first angle (A) between the main part of the instrument and the elongated member is between 0 and 180 degrees, and wherein a first plane (42′) extends perpendicularly to the pivotal axis, so that the elongated main part and the elongated member lies in the first plane,
- a flexible tip (24) provided on the elongated member and exhibiting a conformation which is reversibly changeable from an essentially straight conformation to a loop or hook conformation, wherein the flexible tip, when in the loop or hook conformation, defines an opening with an axial hole going there through, and wherein a second plane (24′) extends perpendicularly to the axial hole through said loop or hook, so that the flexible tip, in its loop or hook conformation, lies in the second plane, wherein
- the flexible tip comprises a dissector and an attachment structure adapted to attach to an implantable medical device,
- the first angle (A) is adjustable independently from the change of conformation of the flexible tip, and
- the orientation of the first plane is different from the orientation of the second plane.
The surgical instrument according to any of the preceding claims, further comprising a control unit adapted to independently control any parameter from the group selected from:
- the change of conformation of the flexible tip, the attachment structure, the first angle (A), the second angle (B), turning of the elongated member around its own axis, turning of the elongated member's two parts around their own axis independently from each other and extension of the main part of the instrument.
