Description

one

This invention relates to medicine, in particular to devices for clamping and holding tissue.

The purpose of the invention is to ensure reliability and reduce trauma when holding tendons.

FIG. 1 shows the tweezers, general view; in fig. 2 - working tips of tweezers, axonometric projection; in fig. 3 - the same second option.

The tweezers contain spring branches 1 and 2 with jaws 3 and 4, at the ends of which are made through longitudinal slots 5. Sponge 3 of greater length is made L-shaped and in contact with the end face 6 of the second sponge 4.

The tweezers can be designed so that the jaws 3 and 4 are made of the same length and one jaw 4 clasps the other 3 along the guiding planes 7.

When using clamping tweezers of the proposed design, the working L-shaped sponge serves as a supporting surface for the tendon and, together with the second sponge, which touches it with its inner surface with grooves, provides atraumatic fixation of the tendons of any size.

ra. The formation of a closed contour by working jaws increases the reliability of holding the tendons in a predetermined position when cutting off the end with a cutting tool, eliminating the possibility of the tendons shifting beyond the limits of the forceps-fixator. Placement and secure fixation of the tendons perpendicularly to the longitudinal grooves of the working jaws are ensured by cutting the ends strictly perpendicular to the longitudinal tendons. A strictly perpendicular cut ensures precise alignment of the ends of the tendons when the suture is applied; The smooth surface of the tendons at the site of the schv, the absence of cracking of the injury of its structures prevents the involvement of the tendons in the cicatricial process, ensures the reliability of the scar and the most complete functional recovery of the tendons.

Strict perpendicular to the cut, smooth surface of the tendons at the site of overlapping of the schv, the absence of wrinkling and injury of its structures using the proposed clamp tweezers also ensure high quality of the overlay of the schv on two levels of the fi autologous and allotendoplasty tendons.
