A surgical suture apparatus for passing a double-ended surgical needle forwards and backwards includes a main body, a first jaw element and a second jaw element, each including a holding device to hold a needle-end of the surgical needle. The first jaw element and second jaw element are movable with respect to each other between a take-over position, where a surgical needle can be passed between the first holding device and the second holding device, and an open position. The surgical apparatus further includes an operating device to operate the first holding device and the second holding device to alternately hold the first needle-end by the first holding device and the second needle-end by the second holding device, where the first jaw element is detachably mounted on the main body.

A hernia repair device including a main body, a plurality of suture needle ports, a plurality of suture needles and a central shaft. The central shaft includes a retractable distal flange disposed at a distal end portion of the central shaft and defines a central channel extending through the main body. The suture needle ports are adjustable between a first configuration in which the suture needle ports are housed entirely within the main body and a second configuration in which the suture needle ports partially extend from the distal end portion of the main body. The suture needles are adjustable between a first configuration in which the suture needles are housed entirely within the suture needle ports and a plurality of second configurations in which the suture needles partially extend from distal end portions of the suture needle ports. A hernia repair mesh is attached to the plurality of suture needles.

A method of suturing a tissue opening can comprise placing a tissue-facing surface of a first pad, a second pad and a third pad over respective tissue areas adjacent to the tissue opening. The second pad can be positioned on a first side of the first pad and the third pad can be positioned on a second side of the first pad. The first and second pads can be coupled to a suture, the suture forming a stitch over the upper surface of each of the respective pads. The suture can be stitched through an area of tissue between the first pad and the second pad, between the second pad and the third pad, and between the third pad and the first pad. A first distal portion and a second distal portion of the suture can be coupled to the third pad for forming the purse-string suture.

Provided in the present disclosure is a puncture core assembly, comprising an operating assembly, a puncture core rod, and a puncture tip used for puncturing human tissue so as to form a puncture opening. The operating assembly is manipulated to generate a driving force. The puncture core rod comprises a transmission assembly and an execution assembly. The transmission assembly transmits the driving force. The execution assembly has a suture actuator, and also has a positioning assembly, a suture assembly, a suture thread release assembly, and a suture needle fixing assembly, which are used to perform positioning when suturing the puncture opening, suture out a needle, release a suture thread, and receive and hold the suture needle respectively.

The present disclosure provides a suture line release mechanism, the puncture core assembly, a puncture device, and a use method of the puncture device. The suture line release mechanism includes a release execution component; the release execution component includes a fixing member and a puncturing tip the puncturing tip is provided with a receiving part; the release execution component has an initial state and a release state; in the initial state, a part of the fixing member is received in the receiving part, and a closed suture line receiving space is formed between the puncturing tip and the part of the fixing member; in the release state, the suture line receiving space is exposed.

A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder includes an inner surface defining a needle passage for holding the needle and a distal opening. The curved needle has a curved needle radius and the curved needle passage has a curved needle passage radius that is different than the curved needle radius and the curved needle frictionally engages the inner surface when the needle is in a retracted position.

Provided is an anastomosis arrangement for joining two opposite stumps of a tubular organ in a streamlined anastomosis procedure. The arrangement includes a pair of axially symmetric stump-coupling members that accommodate pairs of counterpart suturing needles, linked together by common suturing threads, and manipulable by a needle-manipulation element to extract the needles tips from the stump-coupling members for piercing walls of the stump.

A wound closure device can be provided as described herein. In an example, the wound closure device includes a first suture segment having a first suture configuration and a second suture segment having a second suture configuration. The first and second suture configurations can be different from each other. For example, the first suture configuration can includes a first set of characteristics such as barbed or non-barbed, barb sizes, filament sizes, colors, materials, and/or the like and the second suture configuration can include a second set of characteristics such as barbed or non-barbed, barb sizes, filament sizes, colors, materials and/or the like that can be different from the first set of characteristics. The wound closure device can further include connecting section configured to provide a transition from the first suture segment to the second suture segment.

An interlocking two-part sewing needle includes a first needle portion having a needle tip and a second needle portion configured to be inserted into the first needle portion for removably connecting the first needle portion and the second needle portion together. A needle receiver is formed in the first needle portion and is configured to receive the second needle portion when the second needle portion is inserted into the first needle portion. The needle receiver includes one or more non-resistance sections. Each non-resistance section is configured to exert only a friction force on the second needle portion when the second needle portion is inserted into the needle receiver. Additionally, the needle receiver includes one or more resistance sections. Each resistance section is configured to exert a compressive force on the second needle portion when the second needle portion is inserted into the needle receiver.

A device is provided to assist in closing an incision through body tissue that comprises a tubular body sized for introduction through the incision and carrying a plurality of stabilizer elements at the distal end thereof. The stabilizer elements are configured to be deployed within the body cavity to engage the lowermost tissue layer. In one method, the device is pulled with the stabilizer elements deployed to retract the body tissue away from adjacent body structure. In another method, a plurality of needle tips carrying sutures are guided through the body tissue to a retention device at the ends of the stabilizer elements. With the needle tips captured in the retention devices, the device is withdrawn from the incision so that the sutures form ligatures that can be tied off to close the incision.
