8 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

The invention discloses an abdominal cavity puncture stitching instrument, and belongs to the technical field of abdominal cavity puncture stitching equipment, the abdominal cavity puncture stitching instrument comprises a puncture needle head, a needle cylinder, a liquid taking tube, a stitching angle adjusting device, a stitching needle telescopic structure and a liquid extraction structure locking device, the puncture needle head is inserted into an abdominal cavity, the needle cylinder is connected with the puncture needle head in a clamping manner, and the liquid taking tube is fixedly mounted in the needle cylinder; the liquid extraction structure locking device is connected with the puncture needle head in a clamped mode, the liquid extraction structure locking device slides in the needle cylinder in a clamped mode, the suture angle adjusting device is clamped and hidden on the side wall of the needle cylinder, and the suture needle telescopic structure is installed in the suture angle adjusting device in a clamped mode. In order to solve the problems that the operation is still complicated and the suturing angle is relatively fixed when a current puncture mode and a current seroperitoneum drawing mode are switched, the invention provides the abdominal cavity puncture suturing instrument, the problems that the suturing angle cannot be adjusted and the puncture mode and the seroperitoneum drawing mode are inconvenient to switch are effectively solved, and the operation flexibility and the integration level of the whole equipment are improved.

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 is used for laparoscope suture training, and the training effect of student is evaluated objectively and accurately.

A surgical stapler includes a jaw assembly at a distal end connected to a handle assembly that is configured to control the stapler and actuate the deployment of staples. The surgical stapler successfully eliminates intermediate caming portions commonly known as pushers that are located between the staples and a translating slider. The staples are located in pockets at an angle such that the base of the staple is parallel to an angled caming surface of the slider. The translating slider comes into direct contact with staples during deployment as the slider moves through each staple pocket where staples are partially supported by recesses along the slider pathway. The staples are deployed at an angle against the anvil surface. Because there are no pushers, a great deal of space is saved resulting in a much smaller diameter surgical stapler that is particularly suitable for laparoscopic stapling applications.

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.
