Methods for whip-stitching tissue and tissue constructs formed thereby
Methods for whip-stitching soft tissue with a needle and a looped suture avoid placing the tissue graft through the suture loop, which also eliminates the need for passing a tissue clamp through the suture loop. The methods described herein can also include combinations of the techniques described.
Systems, devices and methods of making highly elastic suture needles for minimally invasive surgery
An elastic suture needle for passing through a smaller cannula used in minimally invasive surgery includes an elongated body having a proximal end, a distal end, a length extending from the proximal end to the distal end, a top surface extending along the length of the elongated body, and a bottom surface extending along the length of the elongated body. The elongated body has dimensions that are calculated using the equation T/L.sub.N<(4*σ)/(πE), where T is the thickness of the elongated body, L.sub.N is the length of the neutral axis of the elongated body, σ is the yield strength of the elongated body, and E is the Young's modulus of the elongated body. The elongated body is made of stainless steels such as martensitic stainless steels, austenitic stainless steels, martensitic-aged (mar-aged) stainless steels, and stainless steels sold under the registered trademark ETHALLOY® Needle Alloy.
METHOD AND APPARATUS FOR TREATING A HIP JOINT, INCLUDING THE PROVISION AND USE OF A NOVEL SUTURE PASSER
A suture passer includes a shaft having an axis, a first jaw mounted to the shaft in alignment with the axis, the first jaw being configured to releasably support a length of suture thereon; a second jaw movably mounted to the shaft, and a needle movably mounted to the shaft, the needle having a hook and being configured to reciprocate in alignment with the axis so that the hook can selectively pass by the second jaw and engage suture releasably supported on the first jaw, wherein the first jaw comprises a spring for selectively binding the suture to the first jaw, and further wherein the spring comprises a recess for receiving the suture therein.
SYSTEMS AND METHODS FOR PREPARING REINFORCED GRAFT CONSTRUCTS
Systems and methods for preparing a tissue repair construct for a ligament reconstruction procedure using a reinforced whip-stitching are provided. The described techniques include passing a needle having suture tails attached thereto through a first surface of a graft at an origin point so that a portion of the suture tails exits on a second, opposite surface of the graft while a terminal length of the suture tails is maintained on the first surface of the graft. Multiple suture loops are formed by repeatedly passing the needle with the suture tails around opposite sides of the graft and through the first surface of the graft at subsequent entry points spaced apart along a length of the graft. Each loop is formed so that the construct is reinforced by having a terminal length of each of the suture tails disposed between the first surface of the graft and the loop.
Curled suture device apparatus and method
The present invention provides a suturing device to minimize interference and obstructions during intricate surgeries. The curled suture device is significantly shorter than traditional suturing kits by featuring a needle attached to a specially manufactured thread incorporating a stopping mechanism preceding an angular, semi-rigid portion of thread followed by a curled portion of thread arranged in a corkscrew configuration. The stopping mechanism halts the movement of the thread as the needle and thread intermediate the needle and stopping mechanism is pulled through the suture point, securing the remainder of the thread for access. The semi-rigid portion of thread is thereby utilized in conjunction with its curled portion of thread, allowing for the user's unabated access to the corkscrew configuration to form a ready-made knot, minimizing interference and obstruction during surgery. The thread may be manufactured to form an additional semi-rigid and curled portions of thread upon creation of a knot.
APPARATUS AND METHOD FOR ROBOTIC PROCEDURES WITH MAGNETIZABLE TOOLS
Methods and apparatuses are provided for performing surgery and other interventional procedures on human and non-human animals with a semi-autonomous and/or fully autonomous robotic system. The methods and apparatuses include a system for controlling magnetic fields to dynamically detect the location of magnetizable tools and to manipulate said tools in order to obtain a favorable therapeutic or diagnostic outcome.
SUTURE NEEDLES WITH FLEXIBLE AND NON-FLEXIBLE COMPONENTS
Disclosed is a suturing needle having a thread attachment portion and a ramp portion comprising a tapered portion extending from a proximal end of the needle to cover at least a portion of a suture thread swaged in the thread attachment portion. The tapered portion of the ramp portion provides a smooth transition from a diameter of the suture thread to a diameter of the needle body. The tapered transition portion allows for engaging the suture needle on rollers of a rotational needle driver in one smooth motion. The suturing needle includes a hollow flexible extension component having a distal end and a proximal end, the distal end connected to the proximal end of the thread attachment component, and the proximal end attached to the distal end of the tapered extension ramp portion. The suturing needle can include a combination of flexible and non-flexible sections and/or a combination of straight and curved sections.
Surgical suturing instrument configured to manipulate tissue using mechanical and electrical power
A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.
SIX-DIMENSIONAL BARBED SURGICAL THREAD AND METHOD OF USE
A six-dimensional barbed surgical thread that includes a central core and six first barbs. The central core has a circumference, a proximal end and a distal end that is opposite the proximal end. The six first barbs are positioned around the circumference of the central core so that the first barbs are radially adjacent to each other and obliquely extend from the central core.
Needle and guide apparatus for passing suture
A trocar wound closure system includes a suture passing needle and a guide for directing the needle through the wound site. A distal portion of the needle includes a capture rod with a slot. An obturator tube with a cutout section can be axially actuated to align the cutout section with the slot, and then moved out of alignment so as to capture the suture. The guide includes at least two tracks for directing the needle through the tissue track. A suture catcher is located adjacent to the exit of each track and configured to be actuated from a radially extended configuration to a retracted configuration so as to capture the suture section inserted through each loop. Radially expandable arms at distal section are movable between an expanded configuration and a slender configuration.
