example

[0045] A patient is prepared for arthroscopic rotator cuff shoulder repair surgery in a conventional manner. The patient is anesthetized using conventional anesthesia and anesthesia procedures. The patient is positioned in a conventional manner to perform an arthroscopic Bankart procedure or to repair a torn rotator cuff. Bankart repair restores stability by re-attaching the labrum or capsule directly to the anterior glenoid cavity. Two anterior portal and tow posterior portals are then placed in a conventional manner using a conventional scalpel and conventional cannulas and blunt obturators. A conventional arthroscope is inserted into a cannula and the shoulder is insufflated in a conventional manner with sterile saline to provide the surgeon with a visible field and a view of the surgical site. After examining the site arthroscopically, the instrument of the present invention is armed with a surgical needle and suture and inserted into a cannula and positioned proximate to the su...

Abstract

A needle passer instrument for use in minimally invasive surgical procedures, including arthroscopy. The instrument has upper and lower jaws for engaging tissue and a handle. A removable needle engaging cartridge is mounted to the upper jaw. A surgical needle with attached suture is mounted in a needle passage in the lower jaw. A needle actuation rod engages the surgical needle and pushes the needle through tissue contained between the jaws. The needle is engaged by the cartridge, and the needle may be cut away from the suture.

Description

TECHNICAL FIELD [0001] The field of art to which this invention relates is surgical instruments, in particular, surgical instruments for use in minimally invasive surgical procedures. BACKGROUND OF THE INVENTION [0002] Minimally invasive surgical procedures have proven to be of significant benefit to patients. Typically, in a minimally invasive procedure, a surgical site is accessed using a small incision through a patient's skin and underlying fascia. A conventional trocar cannula may be inserted through the incision to provide a passageway for instruments, scopes, etc. The surgeon may view the operative site remotely or by direct visualization. Many instruments have been developed for minimally invasive surgical procedures including endoscopic and arthroscopic instruments. Arthroscopic instruments that are known and used include, for example, conventional arthroscopic scissors, arthroscopic fastener appliers, and arthroscopic suture passers. [0003] Of particular importance in this...
