Wright Grooved Hook

Description

This Wright grooved hook is plastic and is 3-D printed.  It is for use only on the silicone Strab-Lab model as it is not FDA approved for use on humans in surgery.  It for sale to be used only on the artificial silicone Strab-Lab model.

The Wright Grooved Hook that is used in surgery is made out of titanium and sold by Titan Surgical.  Dr. Wright does not receive a Royalty from Titan Surgical. The Wright Grooved Hook provides excellent exposure for suturing of the muscle insertion during strabismus surgery. The hook lies flat on sclera and the surgeon pulls the muscle insertion horizontally so the insertion is centered in the surgical field. The hook’s length also allows for self-retraction of the conjunctiva so small hooks to retract the conjunctiva are not necessary. The groove is tilted to the sclera at 20 degrees, which ensures consistent suture placement 2.5 mm posterior to the sclera. This avoids inadvertent posterior suture placement that effectively resects muscle lessening the effect of recession. The grooved hook provides added safety as suture passes are over the groove, thus preventing inadvertent scleral perforation. This is especially important when suturing tight muscles, the inferior oblique muscle insertion which over lays the macula, and suturing muscles during enucleation for retinoblastoma. The grooved hook is also very helpful when suturing tight or contracted rectus muscles (e.g., thyroid related strabismus, and congenital fibrosis syndrome) because the hook lies flat on sclera and pulls the insertion into the surgical field without lifting up. In contrast, standard suturing requires lifting the hook up off sclera making the tight muscle even tighter. We find the Wright hook is an in invaluable new tool for strabismus surgery.
