Methods are provided for extracting bone marrow cells from bone obtained from deceased donors, for preparing the bone marrow for cryopreservation and for obtaining desired cells from cryopreserved and fresh bone marrow.

Apparatus and method to permit selective cutting and coagulation required in fine and delicate surgical procedures. The apparatus includes two body members having proximal ends and distal ends with jaw members located adjacent the body member's distal ends. The body members are joined at a pivot located adjacent to the first and second jaw members joining the first and second body members where the body members' rotation about the pivot defines a plane of rotation. The scissors are adapted for selective application of energy to at least one jaw member by a switch located in the plane of rotation.

A surgical cutting instrument (3) having a proximal end (4), a distal end (5), opposing sides (6, 7), and a longitudinal axis (8) and comprising: (i) an instrument body (2); (ii) a pivotal cutting arm (10) having a pinion (20) with an axis of rotation, the pinion being integrally formed with the pivotal cutting arm, wherein the pivotal cutting arm is mounted for rotation relative to the instrument body about a pivot axis (11), the pivot axis being the axis of rotation of the pinion, so that, rotation of the pinion about the pivot axis, causes the pivot arm to pivot relative to the instrument body; (iii) a cutting blade (40) on the pivotal cutting arm for resecting tissue; (iv) a rack (25) that can be moved in a reciprocating linear motion forward towards the distal end and rearwards toward the proximal end, the rack and the pinion being meshed together to forming a rack and pinion mechanism so that linear motion of the rack effects pivotal movement of the pivotal cutting arm about the pivot axis. This provides a very simple yet robust device which can have a minimum cross-section. It can thus be used for minimally invasive procedures such as cutting material from the interior of a spinal disc.

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.

An attainment with an osteotomy surgical instrument for the nasal osteotomy is described; it is set up of at least a couple of lever arms and a couple of sharp spouts that are mutually hinged at least in a rotation fulcrum, where said sharp spouts show an active portion with the cross sectional having a sharp angle, in which the sharp angles of the two sharp spouts are opposed and said active portion extends for a length greater than 30 mm and shorter than 45 mm.

The present disclosure teaches a novel medical device for osteotomy, capable of simultaneous aspiration, cauterization, image-acquisition, irrigation and tissue-protection, adapted for ear, nose and throat procedures, but available or other cavity surgeries.

Methods, systems and apparatuses are provided for torsionally stabilizing a spinal motion segment. One or more implants are placed between two vertebrae to provide torsional stabilization. In particular, one or more implants may be fixed between a superior vertebral body, such as at the spinous process, and an inferior vertebral body. The implants may be connected to the superior vertebral body using a fixation device such as a turnbuckle, an outrigger, a thimble, an endobutton, a suture plug or combinations thereof. The implant may also be connected to the inferior vertebral body using various types of hardware, including staples, screws and anchors. The implant may be kept in tension to provide torsional stabilization and may be comprised of one or more sutures. A multi-functional instrument having one or more arms having holes can be used to clamp onto the superior vertebral body and guide one or more implants to various locations for fixation in accordance with the methods described herein.
