Surgical stapling instruments include mechanisms for identifying and / or deactivating stapler cartridges for use with the instruments. The stapling instrument includes a drive member for actuating a staple cartridge and a locking member movable from a disabled position permitting distal translation of the drive member through a staple firing stroke, to a locking position inhibiting distal translation of the drive member through the staple firing stroke. The staple cartridge may include a switch movable in a lateral direction to either maintain the locking member in the disabled position or to allow the locking member to move into the locking position.

This application provides a drive structure for a surgical suturing instrument and a surgical suturing instrument. The drive structure is disposed in the handle housing of the handle portion of the surgical suturing instrument. The drive structure includes: a trigger rotatably disposed on the handle housing; a rack slidably disposed on the handle housing; a drive pawl movably connected to the trigger; and a mode switching mechanism, including a latch movably connected to the rack, an operable switching slider, and a limiting part fixedly connected to the switching slider. The switching slider drives the limiting part to move between a first position and a second position, so that the drive pawl can switch between a first drive mode and a second drive mode. When the limiting part switches from the first position to the second position, the limiting part switches from a state where it is locked within a preset stroke to a state where it is released from restriction, thereby switching the drive pawl from the first drive mode to the second drive mode.

A surgical suturing device includes a cartridge with a replaceable staple. This cartridge incorporates a blade with a cutting edge that moves between a protected and an exposed position in response to the advancement of the device's drive mechanism. In this description, the blade is pivotally coupled to a cartridge drive carriage, and a spring finger on the carriage moves the cutting edge to the protected position.

This invention relates to the field of medical device technology, specifically to a suturing instrument for minimally invasive suturing of acute Achilles tendon ruptures. It includes a suture guide, a needle holder, and a guide needle. Both the guide needle and the needle holder are arc-shaped, and the arc of the guide needle matches that of the needle holder. The suture guide has an arc-shaped rack inside, and the needle holder is fixedly connected to the arc-shaped rack. Symmetrical arc-shaped grooves are formed on the inner sidewall of the suture guide, with the arc-shaped rack and the arc-shaped grooves slidingly engaged. A rotating shaft is rotatably engaged on the sidewall of the suture guide. One end of the rotating shaft is coaxially fixedly connected to a handwheel, and the other end of the rotating shaft has a driving component for driving the arc-shaped rack to move within the arc-shaped grooves. The suture guide includes a clamping component to prevent the guide needle from falling out. It also includes a guiding system for guiding the guide needle during suturing. This invention designs the guide needle as an arc-shaped structure and allows for telescopic adjustment, keeping the extended portion of the guide needle parallel to the suture guide to reduce puncture resistance and prevent the guide needle from bending or rotating during puncture.

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.
