MIS (Minimally Invasive Surgery) System
PathLoc-L MIS System is for minimally invasive posterior rod and screw fixation. It is designed to minimize soft tissue trauma by using a transmuscular approach and subfascial rod insertion. Patient benefits from the reduced trauma with less pain, shorter hospitalization, and shortened recovery time.
PathLoc-L MIS System is based on a wire-guided insertion of cannulated polyaxial long sleeve screw and sleeve-guided rod insertion through the same incision site.
The instruments have built-in safety mechanisms and provide surgeons with tactile feedback.
The logical flow of the surgery guarantees efficiency and excellent results.
Cannulated polyaxial screw consists of three components: shank screw, tulip of the screw, and pressure valve. The shank screw has a combined thread type where the core has a conical upper region, a cylindrical lower region, and a cylindrical outer thread.
Pressure valve within the tulip head locks the polyaxial screw into a fixed angle screw when used with a torque and a set screw. This also maintains a friction fit allowing the tulip to remain in place during rod and set screw application. 360 ̊ total angulation is possible.
Long sleeve cannulated screw with 30mm extra long thread can make easy reduction of rod with less invasive surgery.
Unique double thread pitch offers improved pullout strength in the vertebral body.
Particular double self-tapping design allows the screw to tap its own hole as it’s driven into the bone.
PathLoc-L MIS Spinal System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in treatment of acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine. Also, PathLoc-L MIS Spinal System can be used in an open and percutaneous approach.
PathLoc-L MIS Spinal System is intended for the following indications:
- Degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies)
- Trauma (i.e. fracture or dislocation)
- Spinal Stenosis
- Curvatures (i.e. scoliosis, kyphosis, and for lordosis)
- Failed previous fusion in skeletally mature patients
