Problems solved by technology

[0002] At present, in order to completely remove the tissue when using the existing anorectal stapler, it is necessary to pull the tissue to be resected into the inner space of the ring knife as much as possible through the traction hole on the staple cartridge sleeve on the main handle. The obstruction of the inner core and the need to install the ring knife and the staple cartridge make the capacity of the internal tissue load smaller, and the operator cannot accurately judge the condition of the internal tissue due to the obstructed view

Embodiment 1

[0059] See Figure 1 to Figure 6 , the anorectal stapler of this embodiment includes a main handle 1, an abutment seat 2, a firing mechanism 3, a functional seat 4, a cutting knife 5, a staple cartridge 6, a transmission assembly 7, an adjustment mechanism 8 and a connecting rod 9.

[0060] The nail anvil 2 and the firing mechanism 3 are arranged on the main handle 1 . The functional base 4 is arranged in front of the nail anvil 2 and is connected with the main handle 1 through a connecting rod 9 . The cutting knife 5 and the staple cartridge 6 are arranged in the functional seat 4 . Driven by the firing mechanism 3 , the transmission assembly 7 makes the cutting knife 5 and the staples 6 - 1 in the staple cartridge 6 cooperate with the staple abutment 2 to realize the function of cutting and stapling. The adjustment mechanism 8 is located on the main handle 1 . The adjustment mechanism 8 adjusts the distance between the functional seat 4 and the nail-anvil seat 2 by adjust...

Embodiment 2

[0076] See Figure 8 , this embodiment is basically the same as Embodiment 1, except that this embodiment further includes a protective cover 11 located between the nail abutment seat 2 and the functional seat 4 . The protective cover 11 includes a left semicircular cover 11-1 and a right semicircular cover 11-2. One side of left semicircle cover 11-1 is connected as a whole with the side of right semicircle cover 11-2, and the other side of left semicircle cover 11-1 is provided with triangular positioning groove 11-3, and the other side of right semicircle cover 11-2 One side is provided with a triangular positioning block 11-4 cooperating with the triangular positioning groove 11-3. The left semicircular cover 11-1 and the right semicircular cover 11-2 are respectively provided with a semicircular groove 11-5, and the two semicircular grooves 11-5 can be assembled into a circular groove. The protective cover 11 is made of plastic material.

Embodiment 3

[0078] See Figure 9 , This embodiment is basically the same as Embodiment 1, the difference is that only one movable handle 3-1 of the firing mechanism 3 is provided in this embodiment. One end of the movable handle 3-1 is connected to the main handle 1 in rotation. The two ends of the handle connecting rod 3-2 are rotationally connected with the movable handle 3-1 and the firing push plate 3-3 respectively, and the end of the handle connecting rod 3-2 connected with the movable handle 3-1 is larger than that of the firing push plate 3-3. The connected end is closer to the front of the main handle 1. The firing push plate 3-3 is connected with the movable handle 3-1 and the transmission assembly 7. The movable handle 3-1 pushes the transmission assembly 7 to move axially behind the main handle 1 through the linkage assembly when the other end of the movable handle 3-1 moves closer to the main handle 1 . The rear portion of the main handle 1 is provided with a return spring...

Abstract

The invention discloses an anorectal anastomat which comprises a main handle, a functional seat and a transmission assembly. The main handle is provided with a nail abutting seat and a firing mechanism; the functional seat is arranged in front of the nail abutting seat and is connected with the main handle through a connecting rod; a cutting knife and a nail bin are arranged inside the functionalseat; the transmission assembly is driven by the firing mechanism, so that the cutting knife, an anorectal nail in the nail bin and the nail abutting seat are matched to realize the cutting anastomotic function. According to the anorectal anastomat, the nail bin and the cutting knife which achieve cutting and anastomosis functions are integrated outside the main handle, and the nail abutting seatis integrated on the main handle, so that the defects of small space and blocked visual field caused by the fact that the nail bin and the cutting knife are integrated on a nail bin sleeve of the mainhandle of a conventional anorectal anastomat are overcome, the capacity bearing tissues of the nail abutting seat is improved, and the visibility of operation is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anorectal stapler. Background technique [0002] At present, in order to completely remove the tissue when using the existing anorectal stapler, it is necessary to pull the tissue to be resected into the inner space of the ring knife as much as possible through the traction hole on the staple cartridge sleeve on the main handle. The hindrance of the inner core and the need to install the ring knife and the staple cartridge make the capacity of the internal tissue carrying capacity relatively small, and at the same time, the operator cannot accurately judge the condition of the internal tissue due to the obstructed view. Contents of the invention [0003] The object of the present invention is to provide an anorectal stapler with large capacity that can carry tissues all the time. [0004] The technical scheme that realizes the object of the present invention is: [0005]...
