Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1, 2, 3, 4 and 5, the laparoscopic linear cutting stapler device includes a stapler 2, a slide hole is axially formed in the stapler 2, a push rod 5 is embedded in the slide hole, and the push rod 5 is slidably connected to the slide hole. The cross section area of the push rod 5 is the same as that of the slide hole, so that the push rod 5 cannot swing up and down in the moving process.

The upper left end of anastomat 2 is provided with pinion rack 9, and swiveling wheel 10 is installed to the left end of push rod 5, and swiveling wheel 10 and the left end swing joint of push rod 5, swiveling wheel 10 can be rotatory around its self centre of a circle department, specifically, swiveling wheel 10 is connected with the left end accessible pivot of push rod 5. The magazine 3 is fixedly connected to the rotary wheel 10. The cross section of the nail box 3 is semicircular, and the diameter of the cross section of the nail box 3 is smaller than 12 mm. The lower nail plate 4 is fixed at the left lower end of the anastomat 2, the end part of the lower nail plate 4 is bent, the shape of the nail box 3 is the same as that of the lower nail plate 4, and the bending angle of the lower nail plate 4 is 60-80 degrees. The outer part of the rotary wheel 10 is provided with a half gear 11, and the half gear 11 is engaged with the toothed plate 9. The radian of the half gear 11 is 30-45 degrees. The stapler 1 is connected to the right side of the anastomat 2, a firing trigger 6 is arranged on the stapler 1, and the firing trigger 6 is used for triggering the push rod 5 to move. When the push rod 5 moves forwards, the rotary wheel 10 and the nail box 3 are pushed to move forwards, and meanwhile, the half gear 11 rotates along the toothed plate 9, and simultaneously, the rotary wheel 10 and the nail box 3 are driven to rotate, so that the nail box 3 also rotates while moving forwards, and the space between the nail box 3 and the lower nail plate 4 is gradually opened. Because the bending amplitude of the lower nail plate 4 and the nail box 3 is large, the lower nail plate and the nail box 3 can not be directly rotated and opened, and the upper surface of the hook at the lower end of the nail box 3 can be prevented from being blocked by the hook at the lower end of the lower nail plate 4 by gradually opening in the forward translation process.

A cutting knife 33 is arranged in the middle of the inner side face of the end part of the nail box 3, a plurality of nail bins 32 are arranged on two sides of the cutting knife 33, and inner inclined supporting faces 36 are arranged on two sides of the inner wall of each nail bin 32. The top of the staple cartridge 32 is provided with a firing aperture 35. The end of the magazine 3 is provided with a bevel 31 for facilitating the clamping of the blood vessel 8. The cartridge 32 is trapezoidal in cross-section. A pin 34 is arranged in the nail bin 32, two sides of the pin 34 are attached to two inner side faces of the nail bin 32, and the lower end of the pin 34 is abutted to an inner inclined support face 36. The cutting knife 33 is parallel to the axis of the nail box 3, the cutting knife 33 is used for cutting off the blood vessel 8, and the pins 34 positioned at the two sides of the cutting knife 33 are used for suturing the cut off blood vessel section.

In using the laparoscopic linear cutting stapler apparatus, the firing trigger 6 triggers the push rod 5 to move and the pin 34 to be fired from the firing hole 35 by the firing means while the lower staple plate 4 and the magazine 3 are clamped. When the push rod 5 moves forwards, the rotary wheel 10 and the nail box 3 are pushed to move forwards, and meanwhile, the half gear 11 rotates along the toothed plate 9, and simultaneously, the rotary wheel 10 and the nail box 3 are driven to rotate, so that the nail box 3 also rotates while moving forwards, and the space between the nail box 3 and the lower nail plate 4 is gradually opened. Because the bending amplitude of the lower nail plate 4 and the nail box 3 is large, the lower nail plate and the nail box 3 can not be directly rotated and opened, and the upper surface of the hook at the lower end of the nail box 3 can be prevented from being blocked by the hook at the lower end of the lower nail plate 4 by gradually opening in the forward translation process. Because the tail ends of the lower nail plate 4 and the nail box 3 are bent, the tail ends of the lower nail plate 4 and the nail box 3 can directly bypass when being blocked by an obstacle 7, at the moment of clamping, the pin 34 is triggered from the triggering hole 35 by the triggering device, the pin 34 is extruded out, the end part of the pin 34 penetrates through the blood vessel 8 and is collided on the inner side surface of the lower nail plate 4, the end part of the pin 34 is pressed and bent by the nail box 3 and the lower nail plate 4 in a squeezing and clamping mode, and therefore the blood vessel 8 is sutured by the pin 34, and the laparoscope linear cutting anastomat device is convenient to use.
