Description

Technical Field

[0001] The invention belongs to the technical field of stapler actuators, and in particular relates to an actuator for an electric cutting stapler. Background Art

[0002] The stapler actuator refers to the collective name for a series of transmission components and action components used to sew up the wound during the use of the stapler. The actuator can be a component for adjusting the transmission or a component for direct action.

[0003] The actuator of the cutting stapler in the prior art mainly includes a handle shell, an actuator chamber, a motor frame, a driving motor, a ring gear block, a rack metal rod, an outer tube, an inner tube, a core rod, an adjustment round block, a connecting swivel, a nail magazine, a nail seat, an operating handle, a shift block, a locking block and a driving power supply. When in use, the angle of the outer tube can be adjusted by adjusting the round block, thereby driving the nail seat and the nail magazine to move. Under the action of the connecting swivel, the left and right angles of the nail seat and the nail magazine can be adjusted. Under the action of the operating handle and the shift block, the outer tube, the nail seat and the nail magazine can be driven to cooperate for clamping. Under the action of the ring gear block and the rack metal rod, the core rod, the nail seat and the nail magazine can be driven to cooperate for clamping.

[0004] However, the rotation of the drive motor and the ring gear block is electrically driven, and thus requires the assistance of circuit tools such as circuit boards. Once a circuit board failure occurs, the drive motor will get stuck or be unable to stop, causing the core rod to drive the nail magazine and the nail seat to make an unpredictable movement trajectory, thereby causing harm to the human body. Since the drive motor and the ring gear block are located on the inner wall of the handle shell and the execution magazine, measures cannot be taken in time to stop it, thus causing a safety hazard.

Under the action of the dovetail slider, the third rectangular block and the push block, the rubber block and the baffle plate can be driven to move, so that the rubber block can slow down the rotation speed of the guide block. Under the action of the baffle plate, the guide block can be fixed, and the ring gear block can be fixed. At this time, under the action of the first threaded rod, the resistance block can fix the dovetail slider.

[0023] 3. The actuator of the electric cutting stapler is provided with a cleanable actuator head device. Under the action of the hole groove, the human tissue debris on the nail seat can fall into the hole groove at the moment the nail in the nail magazine is pressed. Under the action of the rotating rod, the cross plate and the bottom plate can be driven to rotate, so that the curved hook bristles can clean the nail holes, thereby preventing human tissue debris from remaining in the nail holes and affecting the normal use of the nails in the nail seat and the nail magazine.

By arranging the dovetail sliding rod 915 and the cylinder 916, the effective length of the hook bristles 919 can be adjusted when the rotating rod 911 rotates. The bottom of the cylinder 916 is fixedly connected to a bottom plate 918, and the bottom of the bottom plate 918 is fixedly connected to a hook bristle 919. The outer surface of the dovetail sliding rod 915 is sleeved with a third spring 917, and the two ends of the third spring 917 are respectively fixedly connected to the cylinder 916 and the cross plate 914.

[0041] The working principle of the present invention is:

[0042] S1. When the ring gear block 53 needs to be urgently fixed, the dovetail slider 592 is pushed, so that the dovetail slider 592 can drive the third rectangular block 593 and the push block 594 to move, and then drive the rubber block 595 and the baffle 596 to move, and then contact the guide block 519 to stop it from moving. At this time, the first threaded rod 597 is rotated so that the resistance block 598 fits with the dovetail slider 592 for fixation. At this time, the pressing rod 516 is pressed downward, so that the third disc 515 and the second disc 58 move downward. At this time, the third disc 515 and the second disc 58 can be moved downward. The second spring 514 is deformed, and the first rectangular block 52 slides in the rectangular through groove 513, and the second rectangular block 517 is separated from the second rectangular groove 55, so that the dovetail slide bar 511 can drive the second disc 58 to separate from the first circular groove 54 at the bottom of the ring gear block 53, and the third disc 515 is fixed to the first circular groove 54 at the top of the ring gear block 53. At this time, the pressing rod 516 is rotated, so that the pressing rod 516 drives the ring gear block 53 to rotate, and then drives the rack metal rod 6 to move, so as to retract the nail seat 92 and the nail magazine 95;

[0043] S2. When the adjusting round block 7 needs to be fixed, the second threaded rod 82 is rotated so that the second threaded rod 82 can drive the first screw hole block 84 to move, and then drive the L-shaped plate 85 to move, and then drive the extrusion block 87 to move, so that the pointed protrusion 88 on the extrusion block 87 can be fixed with the first rectangular anti-sliding block 810, and the third threaded rod 811 is rotated so that the third threaded rod 811 can drive the extrusion plate 813 to move, and then drive the second rectangular anti-sliding block 814 to be fixed with the third rectangular anti-sliding block 816;

[0044] S3. When the inner wall of the nail seat 92 needs to be cleaned, the rotating rod 911 is rotated at this time, so that the rotating rod 911 can drive the horizontal plate 914 and the bottom plate 918 to rotate, and then drive the curved hook bristles 919 to rotate, and then clean the nail hole 96. During the rotation process, the dovetail sliding rod 915 will continuously slide on the inner wall of the cylinder 916, thereby adjusting the effective length of the curved hook bristles 919.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0046] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
