A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insertible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.

A detachable rongeur has a main body, a slider and a movable handle. A front end of the main body has a cutting edge. The movable handle is hinged to both the main body and the slider. The movable handle can drive the slider to move along first sliding grooves. A cheek portion of the main body includes a trigger lock catch structure. The movable handle can be pulled back and forth. An upper portion of the movable handle includes a first feature portion and a second feature portion that are sequentially arranged from bottom to top. The trigger lock catch structure abuts against the first feature portion or the second feature portion.

A collector used to collect bone includes: a container body defining an interior containment space for receiving and retaining collected bone, and having at least one open end for access and removal of collected bone from the interior containment space; and a cap in covering relation to the open end of the container body such that access to the interior containment space for removal of collected bone is inhibited. The collector includes an intake port defining an opening for receiving therein a distal end of a kerrison rongeur for collecting cut bone from a cutting area thereof, and the cap includes at least one scraper for engaging and dislodging cut bone from the cutting area of a distal end of a kerrison rongeur when received within the intake port. The collector preferably is used with a kerrison rongeur for collecting cut bone therefrom.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

The present invention relates to an orthopedic surgical pliers-like tool (1) for performing surgery on the patella bone, comprising: at least a couple of jaws (2, 3) coupled to corresponding handle members (12, 13) pivotally mounted with a hinge bolt (5) in relation with one another; a distal clamp portions (8, 9) on each jaw (2, 3) for gripping and holding at least the periphery of a patella bone; an intermediate force transmission mechanism (4) between the tool handle members (12, 13) and the jaws (2, 3); a couple of arms (20, 30) in said intermediate force transmission mechanism (4) structurally independent from the handle members (12, 13) and interposed between the handle members (12, 13) and the jaws (2, 3); an elastic member (25, 35) in each arm (20, 30) for coupling each arm to a corresponding handle member (12, 13) in a first linking point (38, 39); a second more distal linking point (31, 33) in each arm (20, 30) engaging a corresponding distal end (43, 42) of a handle member (12,13); the first linking point (38, 39) of one arm (20, 30) and the second linking point (31, 33) of the other arm being cross linked to the same handle member (12, 13).

Improved spinal instruments are provided. In particular, the present application relates to an improved rongeur that allows for multiple bites of bone to be performed in a patient before removing the rongeur from the patient. The rongeur includes a lower shaft and an upper shaft slidable relative to the lower shaft. The lower shaft and upper shaft form a jaw mechanism that can take multiple bites of bone, which can be deposited in a storage cavity formed in the upper shaft. To assist in removing the bone from within the storage cavity, an internal plunger mechanism can be provided that is actuated by a finger hold. In addition, at least portions of the upper shaft are detachable from the lower shaft such that the upper shaft can be thoroughly cleaned and re-used if desired.

A bone punch includes a base body with a guide shaft (3), a handle (4) and a punching slide (8) supported adjustably along an upper guiding surface (13) of the guide shaft (3). An actuating lever (6) with an adjusting lever (65) interacts with the punching slide (8) for adjustment against a spring action of a restoring spring (46). In a distal end area (10), the punching slide (8) has a securing element (45), which extends between two side walls (25, 26) of the punching slide (8) on the guide shaft (3). The securing element (45) has two laterally protruding positive-locking elements (51, 52). Each side wall (25, 26) is provided with an inner, distally limited longitudinal groove (40, 41) running in the longitudinal direction (9) of the guide shaft (5). Each positive-locking element (51, 52) is longitudinally displaceably inserted into a respective one of the grooves (40, 41).

A rongeur cutting system and method of operating said system. The rongeur cutting system may comprise a cutting unit that includes an outer tube and a cutting implement capable of both oscillation and longitudinal movement within the outer tube. The rongeur cutting system may also comprise a handpiece including a power source and spindle for actuating the cutting implement. The spindle is designed to allow the cutting implement to oscillate while simultaneously moving longitudinally relative to the spindle. The handpiece may further comprises an advancement and retraction assembly that selectively displaces the cutting implement so the distal end of the cutting implement can be advanced towards and retracted away from the distal end of the outer tube. The method of operating the rongeur cutting system may comprise manually operating the system to move the cutting implement longitudinally while periodically actuating the power source to simultaneously oscillate the cutting implement.

A tissue treatment device has a shaft assembly including an outer sleeve and an inner sleeve. The inner sleeve is co-axially and rotatably received in an axial passageway in the outer sleeve. A dielectric housing has an outer cutting window forming a distal portion of the outer sleeve, and a distal portion of the inner sleeve forms an RF electrode and has an inner cutting window formed therein. The outer and inner cutting windows have outer and inner cutting edges disposed to close together as the inner sleeve is rotated relative to the outer sleeve.
