Needle for delivery of dermal filler threads
Provided herewith is a needle for delivering dermal filler thread to a wrinkle in a patient. The needle can also be used to deliver the thread to a patient for the purposes of facial contouring. The needle comprises a coupler for attaching the thread to the needle and also a trocar to ease delivery through the skin.
Suturing device
A suturing device includes a longitudinal axis member, an operation unit, a grasp portion, a suture needle, a first engaging member, a second engaging member, a first linear member connected to the first engaging member and the operation unit and configured to switch the first engaging member and the engaging portion into an engaged state or a disengaged state, and a second linear member connected to the second engaging member and the operation unit and configured to switch the second engaging member and the engaging portion into an engaged state or a disengaged state, wherein the first and the second linear member intersect a central axis of the longitudinal axis member between the grasp portion and a distal end of the longitudinal axis member and are inserted into an insertion path to be connected to the operation unit.
DEVICES AND METHODS FOR MINIMALLY INVASIVE SUTURING
Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.
APPARATUS AND METHOD FOR MINIMALLY INVASIVE SUTURING
An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle.
DENTAL SUTURING NEEDLE
The present invention provides a dental suturing needle comprising a needle part provided with a needle point, and an eye part extending from the needle part and provided with an eye of the needle, wherein between the needle part and eye part is a curved part which is structured so that the needle part slants to the left or right by 20-45 with respect to the eye part. The present invention provides a three-dimensional suturing needle structured so that the needle part curves laterally by a set angle two to three times from the eye part to thus facilitate securing suturing space inside the mouth cavity, remove discomfort to the hand due to easy access to the treatment area, and allow smooth suturing without having to apply excessive pressure to the wrist, and additionally, the present invention is a very useful invention which creates spaces that do not come into contact with tissues to thus allow smooth movement of the suturing needle and minimize damage to the tissues.
Apparatus and method for tissue closure
A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

SURGICAL SUTURE ASSEMBLY
Surgical suture assemblies, and methods of their use, are disclosed having configurations suitable for closure of biological tissue, including the bony tissue of the sternum. The surgical suture assemblies described or contemplated herein have physical characteristics that help to mitigate undesirable issues, such as bleeding.
Methods, systems and devices for attaching surgical sutures to surgical needles and testing armed surgical needles
A method of attaching a surgical suture to a needle and testing the attachment includes dispensing a length of suture from a spool by using a first suture gripper, and using a surgical needle gripper for holding a surgical needle stationary. A leading end of the suture is inserted into and attached to a receiving end of the surgical needle. A second suture gripper is located between the first suture gripper and the spool. After the second suture gripper is closed for gripping the suture, the second suture gripper is advanced downstream toward the surgical needle to reduce the tension on the suture. The tension on the suture is reduced by moving the second suture gripper a pre-determined distance. The first suture gripper is opened for releasing the suture and the first suture gripper is moved toward the suture spool for re-grasping the suture at a location between the second gripper and the suture spool. The suture between the downstream side of the re-positioned first suture gripper and upstream side of the second suture gripper is cut. After the suture is cut, the second suture gripper is displaced toward the spool using a tension control system to increase the tension level between the needle and the second suture gripper.
Automated needle loader
An apparatus for loading suture needles into a surgical instrument comprises a body, a first movable member, an engagement feature, and a needle. The body has a channel configured to receive a surgical instrument. The engagement feature is configured to open a cover of a surgical instrument upon insertion of a surgical instrument into the channel of the body. The first movable member is configured to deliver the suture needle to a surgical instrument after a surgical instrument has been inserted into the channel and the cover has been opened. The apparatus may further comprise a second movable member configured to facilitate delivery of the needle to a surgical instrument in conjunction with the first movable member.
