Abstract:
본 발명은 양바늘 봉합사의 양쪽 끝부분에 위치식별부를 형성하여 혈관, 요도, 요관, 정관, 기관지, 창자 등 관형태로 이루어진 조직의 봉합시 봉합사의 봉합위치와 좌우를 시술자가 쉽게 인지할 수 있도록 하여 정확하고 안전한 봉합수술이 이루어질 수 있도록 한 수술용 양바늘 봉합사에 관한 것이다. 즉, 본 발명은 필라멘트의 양단에 바늘이 결합된 양바늘 봉합사에 있어서, 상기 필라멘트의 양단부에 봉합사의 봉합되는 위치를 나타내는 위치식별부가 각각 형성되어 있는 것을 특징으로 한다.
Abstract:
According to an aspect, a medical device may include a needle member, and a handle coupled to the needle member. The handle may define a track portion. The medical device may also include a pusher member having a sheath disposed around a portion of the needle member, and an extension member being movably coupled to the track portion of the handle such that the pusher member is configured to move from a first position to a second position during a surgical procedure. The pusher member may be removable from the handle. The sheath may define a slot, and the pusher member may be removable from the needle member through the slot.
Abstract:
The invention provides methods and devices for treating liver cirrhosis or portal hypertension by creating an intrahepatic shunt, or new passage, from a portal vein of a patient to a hepatic vein using a device with intravascular imaging capabilities and pressure sensing capabilities or positioning mechanisms. The integration of intravascular imaging aids in the precise placement of the shunt and pressure measurement may verify successful shunt creation. An apparatus may include a catheter with an extended body for insertion into a hepatic vein of a patient, an intravascular imaging device and a needle exit port on the distal portion of the extended body, and a needle disposed within a lumen in the catheter and configured to be pushed out of the exit port and extend away from a side of the extended body, in which the needle includes a pressure sensor.
Abstract:
A surgical instrument (1) intended for fitting a urogenital implant (4) comprising a support strip intended to support the urethra, said implant (4) being intended, once fitted, to extend longitudinally from the root of a first thigh (C1) to the root of the second thigh (C2), passing through the first and second membranes blocking the obturator foramens, said surgical instrument comprising a needle having a distal end (149), that is preferably pointed, and a proximal end rigidly connected to a gripping means (12). According to the invention, the length portion of the needle useful for dissection, from said distal end (149), is sufficient and is shaped in space, without discontinuity of curvature, in such a way as to allow the urogenital implant (4) to be fitted with a single pass of the needle, from the root of a first thigh (C1) and along a trajectory of the needle passing consecutively through the first membrane (O1) of a first obturator foramen, and the suburethral area between the vagina (V) and the urethra (U) in a woman.
Abstract:
A surgical stapler includes a handle assembly (80) made of paper pulp products or other eco-friendly material. The handle assembly and components of the staple mechanism housing are designed to account for the decreased material strength of the handle assembly. A new retainer clip (81) or handle retainer includes assembly ribs (82) which include interference fit ribs (96). The retainer clip (81) in combination with a raised circular boss (16) of the handle assembly facilities the use of lower strength materials, such as paper pulp products. An efficient staple housing mechanism includes the use of new staple carrier assembly fixture pin (86) and other disclosed components.
Abstract:
A system and method for ensuring safe and tolerable insertion of a needle into a subject's body according to a preplanned or continuously monitored sequence of insertion steps. The system comprises a gripping device for gripping the needle in order to perform robotic insertion steps, yet for releasing the grip between such insertion steps, until the next insertion step is initiated. Thereby, the robot has full control of the needle during insertion steps, but does not constrain the needle between insertions, such that movement of the subject can cause neither damage nor discomfort. The gripping and insertion steps may be coordinated to keep in synchronization with the subject's breathing cycles, such that the insertion steps may be performed in the same segment of each cycle of motion of the subject's chest. The gripper can either fully disconnect from the needle, or can partially disconnect but constrain motion within limits.
Abstract:
A device for accessing the intra-thoracic space without the need for a thoracotomy or sternotomy includes a cannula having a shaft positionable through a supra-sternal incision into a retrosternal space and a stabilization system for supporting the cannula in a fixed position. The cannula includes illumination features used to illuminate the retrosternal space, giving clear, direct visualization of the retrosternal space during dissection to, and performance of procedures at, the surgical site.
Abstract:
An anchor device and system for coupling soft tissue to osseous tissue includes a stopper member that supports a loop of suture material. A fixing member includes features that allow it to be rigidly coupled to surrounding bone and thus hold the stopper member in a cavity within the bone. The loop of suture material, in turn, supports a second suture device, which is coupled to, and thus retains, the soft tissue. In certain embodiments, the fixing member includes a wadding structure having a generally elastic property.
Abstract:
A novel silicone coating process for surgical needles is disclosed. Coating solutions are applied to a surgical needle and a stream of air is directed at the needle in a direction substantially parallel to the central longitudinal axis of the distal section of the needle, providing superior coatings and performance.
