Description

Bone penetrating suture instrument {Transosseous Surgical Instrument}

The present invention relates to a suture device, and more particularly, to an anchorless suture device, which is easy to use and allows entry of a suture in a direction required by an operator, and allows replacement of various tools depending on circumstances. It relates to a bone penetrating suture device capable of applying a constant force at the time of application.

When conservative treatment is not possible in treating torn or damaged tissues, surgical treatment is required. At this time, methods such as cortical buttons, screw reinforcement, suture tape, and anchors are used. In particular, the suture method using anchors is used. It is widely used due to its ease of use and high initial fixing strength.

In the surgical procedure using an anchor, a micro-incision is made in the lesion area or an arthroscopy is performed to confirm the lesion area, then the muscle or ligament in the lesion area is fixed with a suture, an anchor with a suture is inserted, and the detached ligament or muscle is stitched up and attached to the bone. It uses a complicated method of fixing it by making a knot.

However, re-ruptures or re-fractures often occur in rotator cuff tears or fractures. Existing anchor sutures have a problem in that reoperation is difficult, and although they are well fixed in the early stages after surgery, the anchors become dislodged from the fixation position over time, or the suture Problems such as knots colliding occur.

In addition, conventionally used guiders for penetrating the tibia and femur are supported by driving sharp studs at the end of the support arm into the inner surface of the tibia, adjusting the guide tube to be supported on the outer surface of the tibia, and then drilling through pins at the rear ends In this method, a penetrating tube is inserted into the guide tube and drilled through the tibia from the bottom to the top of the penetrating pin to create a penetrating tunnel, but there is a problem in that the operation takes a long time.

In order to solve these problems, recently, as one of the anchorless suture methods, TRANSOSSEOUS has been used, and the bone penetrating suture is a suture method in which a small hole is drilled in a bone or muscle and a suture is inserted into a tunnel.

Accordingly, there is an advantage in that a tunnel is drilled in the place where the anchor was located to perform reoperation or, in the case of the TRANSOSSEOUS method, reoperation is possible without re-piercing the tunnel. Also, in the case of the TRANSOSSEOUS method, the cost is generally lower than that of the anchor method. It has the advantage of simple process, and its use is increasing.

However, in the case of a conventional bone piercing suture device, not only is it inconvenient to use, but it is difficult to respond to various situations and there is a problem that excessive force and effort of the user must be accompanied during the actual bone piercing procedure.
