5 results about "Laparoscopic suture" patented technology

A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.20 24 22 73 26 15 O ct 2 02 4 A B S T R A C T O F T H E D I S C L O S U R E 2 0 2 4 2 2 7 3 2 6 1 5 O c t 2 0 2 4

This invention relates to the field of medical device technology, and more particularly to a laparoscopic suture device, comprising a fixed handle, an operating lever mounted on one side of the fixed handle, a movable cover plate disposed on one side of the operating lever, a clamp assembly installed inside the movable cover plate, and an adjustment component disposed on one side of the fixed handle, the adjustment component including a rotating wheel disposed on the top of the fixed handle. This invention, by incorporating a rotating wheel, a swing-rotation switch, and an angle controller, achieves flexible adjustment of the clamp assembly in multiple directions and angles, solving the problems of limited adjustment range and inconvenient operation of existing laparoscopic suture devices, enabling the instrument to better adapt to complex anatomical morphologies; the inclusion of a cover plate toggle and a movable handle improves the convenience of opening, closing, and locking operations; the rounded corner design of the clamp assembly surface reduces sharp edges, improving passability and safety; markings facilitate rapid identification of the suture needle position during surgery, effectively improving suturing accuracy and surgical efficiency.

The utility model discloses a surgical suture training model and simulation training device, including bottom plate, main control board, is equipped with at least two simulation suture incision on the bottom plate, and the inside of simulation suture incision is equipped with two opposite conductive detection elements, and the periphery symmetrical layout has a pair of metal contact, respectively as starting contact and end contact, and the main control board is arranged in the inside of bottom plate, and two conductive detection elements are respectively through the wire electricity connection main control board, and is equipped with timing module on the main control board, and starting contact and end contact electricity connection timing module. The utility model is used for laparoscope suture training, and the training effect of student is evaluated objectively and accurately.

This invention provides a continuous reciprocating laparoscopic suture device, comprising an actuator body, a control body, and a control connecting rod. The actuator body has a curved needle module for mounting a curved needle, and the curved needle module contains a curved needle reciprocating drive mechanism for driving the curved needle's reciprocating motion. A curved needle module support is located at the first end of the control connecting rod for mounting the curved needle module. The second end of the control connecting rod is connected to the control body, and a control wire, including a suture drive wire, is threaded through the control connecting rod. The first end of the suture drive wire is connected to the curved needle reciprocating drive mechanism, and the second end extends into the control body. Compared to the 360-degree circumferential rotation of the curved needle, this invention provides smoother puncture of human tissue. The suture drive rocker arm on the control body facilitates convenient switching between curved needle reciprocating motion during surgical suturing, further improving the efficiency and quality of the suturing surgery.

The application discloses a special device for abdominal cavity opening suture, and belongs to the technical field of medical instruments. The device aims to solve the problems of traditional suture instruments, such as difficult closure of the inner incision, risk of mis-suture of adjacent organs, lack of real-time tension feedback and visual guidance function, and the like, in patients with thick subcutaneous fat tissue due to the limited depth of entry. The device comprises a guide sheath, a puncture execution mechanism and a tissue clamping assembly. The device realizes non-axial puncture through the deflection outlet and the arc transition section, the tissue clamping assembly clamps the inner incision edge, and the double-line loop suture structure enhances the gripping force, so that accurate operation can be guided and ensured and organ damage can be avoided. The suture device can effectively improve the accuracy, safety and standardization degree of abdominal wall suture of patients with thick fat layer, and reduce the risk of postoperative complications.
