SURGICAL INSTRUMENT FOR SOFT TISSUE FIXATION Russian patent published in 2025 - IPC A61B17/04 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a surgical instrument for soft tissue fixation. Surgical instrument for soft tissue fixation is made in the form of a screwdriver containing a sting, a handle and an anchor fixture. Screwdriver contains a suture retainer. Sting is made with longitudinal slots for laying the suture material. Anchor retainer is made in the form of a rod with a screw thread having a taper decreasing towards the distal end of the anchor retainer, and is installed on the distal end of the screwdriver bit with possibility of its removal and replacement. Suture retainer is configured to fix and retain the suture material in the longitudinal slots of the screwdriver bit during manipulations during a surgical intervention. At the end of the distal end of the handle there is a groove that forms protrusions on its sides for orientation and fixation of the suture material retainer on the screwdriver in the extreme proximal position.

EFFECT: use of the invention enables to protect the contacts of the suture material both with the cortical layer of the bone and with other tissues of the patient throughout the length of the instrument during surgical manipulations; to increase strength of installed retainers and anchors; and also to provide the possibility during surgical manipulations to replace anchor fixators and/or suture material with another type or size.
