Weldix® Anchor - The revolutionary ultrasonic micro-suture anchor

Product overview

Providing excellent anchorage – even without cortical bone.

Fully resorbable
Outstanding strength
No micromotion

Dimensions

The Weldix^® Anchor is 2.3mm in diameter and 7.2mm in length and requires a drill hole of 1.8mm in diameter and 7.6mm in depth.

Material

The implant is made of biocompatible and fully bioresorbable Polylactide (PLDLLA 70:30). The in vivo degradation of the Weldix^® implant provides progressive loading during the healing process.

Degradation process

The Weldix^® 2.3mm Anchor degrades due to the natural physiological process of hydrolysis, which results in a complete metabolization of the polymer into H₂O and CO₂ over 18 months.

Indications

The Weldix^® 2.3mm Anchor can be used for several procedures in cats and dogs, including:

Hip luxation (capsule repair, ligamentum teres femoris repair)
Tarsal collateral ligament repair
Achilles tendon repair
CCL extracapsular repair
Knee collateral ligament repair
Elbow / Shoulder luxation repair

Weldix^®2.3mm Anchor Pullout Strength

The Weldix^® 2.3mm Anchor shows superior pullout strength compared to conventional anchors

All Suture Anchor: Anchor made from suture only, forming a knot in the bone while tightening

Mechanical Suture Anchor: Titanium anchor having mechanical retention structures like barbs or threads to create a hold in bone

Sutures

The Weldix^® 2.3mm Anchor can be used in combination with the following sutures:

Sutures are not included in the package.

Suture clip function

The Weldix^®2.3mm Anchor features two transverse apical “click-in” grooves for positioning the suture before implantation.

Ultrasonic Generator

Weldix^® Anchors must be implanted with the BoneWelder^® Vet ultrasonic generator.

The twist drill (with or without drill stop) is sized specifically for the Weldix^® 2.3mm Anchor. It helps ensure safe and easy handling of the implants and correct implantation.

Animated Implantation Process for the

Weldix^® Suture Anchor

Implantation Process

Drilling

A pilot hole is drilled into the bone to the depth of the integrated stop. The drill bit is equipped with a countersink to help position the anchor during implantation.

Mounting

The Weldix^® 2.3mm Suture Anchor is placed on the tip of the sonotrode. Its precise geometry ensures a secure fit. The suture is clamped into the clip at the tip of the Weldix^® 2.3mm Anchor and the anchor is positioned above the pre-drilled hole.

Implantation

Ultrasonic energy is applied, and the outer portion of the Weldix^® 2.3mm Suture Anchor polymer liquefies. The polymer infiltrates the surrounding bone and immediately solidifies, locking both the implant and suture securely in place. Immediately after implantation, the suture is loadbearing.
