摘要: A stapling head assembly of a suturing and cutting apparatus for endoscopic surgery includes a cartridge, a cartridge support detachably connected to the cartridge, an actuating block including an unlocking component set movably in the cartridge, a cutter, and a lockout mechanism. The cutter is adapted to move longitudinally along the cartridge, between a first position and a second position. The mechanism includes a lockout block set in said cartridge support and transversely movable with respect to the support between third and fourth positions, and a flexible component set between the support and the lockout block and actuating the lockout block to move from the third to the fourth positions. When the flexible component is under compression, the cutter can move from the first to the second positions. After the actuating block is actuated, the lockout block moves to the fourth position under action of the flexible component.

摘要: Disclosed is a linear cutting stapler comprising an upper jaw and a lower jaw capable of being closed or open relative to each other. Said upper jaw includes an anvil and said lower jaw includes a staple cartridge frame. The proximal end of said anvil is provided with a positioning pin, and the proximal end of said staple cartridge frame is configured with a pin slot; or, the proximal end of said staple cartridge frame is provided with a positioning pin, and the proximal end of said anvil is configured with a pin slot. Wherein, said pin slot comprises a first slot position and a second slot position which are engaged with said positioning pin, and, said first slot position and said second slot position are partially combined and arranged in an angle with each other. When said upper jaw and said lower jaw rotate from closed state to open state with said positioning pin as a support shaft, said positioning pin actively rotates from said first slot position to said second slot position in which it gets stuck. While the upper jaw and the lower jaw are closed, the positioning pin is engaged with the first slot position to locate the upper jaw and the lower jaw related to each other. After the upper jaw and the lower jaw are open, the positioning pin gets stuck in the second slot position, by this time the operator can lift up the whole stapler by holding upper jaw or lower jaw, which is convenient for re-locating the tissue and simplifies the operations.

摘要: A linear suturing and cutting device, comprising an upper jaw and a lower jaw capable of being closed or opened relative to each other; said upper jaw includes an anvil; said lower jaw includes a staple cartridge frame, said staple cartridge frame is detachably provided with a staple cartridge, said staple cartridge is arranged with cartridge holes inside which run throughout said staple cartridge to its working surface, and staple pushers correspondingly disposed inside said cartridge holes and being capable of sliding relative to said cartridge holes, said staple cartridge frame is slidably provided with a firing piece inside, said firing piece is configured with a wedge-shape staple pushing member capable of driving said staple pushers to slide in said cartridge holes, said cartridge holes are configured to be inclined towards the distal end of said staple cartridge. In this way, the direction of force received by the staple pushers is identical with the extending direction of cartridge holes during the staple pushers being pushed in the cartridge holes, thus the staple pushers will not get too large friction from the inner wall of cartridge holes and then can be pushed more smoothly, which reduces the difficulty of operation.

摘要: A stapling head assembly includes a cartridge support having a proximal end, a connecting tube, a cutter pushing rod, and a lockout mechanism. The tube includes a distal end connected to the proximal end. The rod is movably set inside the tube. The mechanism is connected to the tube, and includes a pressing block and a pushing block. The pressing block is used to lock the proximal end to prevent the rod from moving before the assembly is used. The pressing block is rotatable between a first position and a second position relative to the tube. The pushing block is used to push the pressing block to rotate from the first position towards the second position. The pushing block is located at one side of the pressing block, and is movable between a third position and a fourth position relative to the tube along a longitudinal direction.

摘要: An introducer accessory for being fitted with a circular stapler is disclosed, and pertains to the technical field of medical instrument. The introducer accessory at least comprises a sleeve portion sleeved around a distal end of the circular stapler and an introducing portion disposed at a distal end of the sleeve portion. And the introducing portion comprises a spiral member in a conical shape with a cavity and a traction member, the traction member extends in the cavity of spiral member to connect with the distal end of the spiral member such that when the traction member is pulled by an external force, the distal end of the spiral member is pulled out by the traction member through the cavity which causes the spiral member to be unwound internally and finally to form a strip body to withdraw through the circular stapler. Thus, the withdrawing process of introducer accessory can avoid injury to patient during surgery.
