In order to achieve the purpose, the invention adopts the technical scheme that: an elastic mechanism for a linear cutting anastomat is arranged at the front end of a fixed seat of the linear cutting anastomat and comprises a composite elastic body and a quick-assembly box, wherein the block-assembly box is arranged on the fixed seat, and the composite elastic body is inserted into the quick-assembly box; the composite elastic body comprises a base, a forward elastic sheet, a backward elastic sheet and a positioning elastic sheet, wherein the positioning elastic sheet is arranged at the front end of the base; the forward elastic sheet and the backward elastic sheet are simultaneously arranged at the rear end of the base.
As a further improvement of the invention, the quick-assembling box is arranged on the fixed seat in a glue-assembling mode.
As a further improvement of the invention, the quick-loading box is a shell with an opening at one end, and a positioning through groove is formed on the upper end surface of the shell; an inclined plane is arranged on the upper side of the opening end of the shell; the height of the inner cavity of the shell is larger than the thickness of the base.
As a further improvement of the invention, the backward elastic sheet is symmetrically arranged relative to the forward elastic sheet; the upper end faces of the backward elastic sheet and the forward elastic sheet are positioned in the same horizontal plane; the included angle of the backward elastic sheet and the included angle of the forward elastic sheet relative to the horizontal plane are both 30-40 degrees, and the installation directions of the backward elastic sheet and the forward elastic sheet are opposite.
As a further improvement of the invention, the included angle between the positioning elastic sheet and the upper end surface of the base is 25-30 degrees.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
the assembly and disassembly are convenient, and the composite elastic body can be fixed only by directly inserting the composite elastic body into the quick mounting box during assembly; when the quick assembling box is disassembled, the composite elastic body can be taken out from the quick assembling box only by pressing down the positioning elastic piece.
The design of backward elastic sheet and forward elastic sheet has increased the elasticity contact scope, makes the anastomat atress at the dismouting in-process even, is difficult to produce and rocks each other or move, alleviates doctor's intensity of labour.

The technical scheme of the invention is further explained by combining the accompanying drawings as follows:
FIG. 1 is a schematic view of an assembly structure of the present invention;
FIG. 2 is a schematic structural view of a composite elastomer of the present invention;
FIG. 3 is a schematic structural view of the quick package of the present invention.
In the figure: 1. quickly packing the box; 1-1, a shell; 1-2, inclined plane; 1-3, positioning a through groove; 2. compounding an elastomer; 2-1, a base; 2-2, positioning an elastic sheet; 2-3, a forward elastic sheet; 2-4, backward elastic sheets; a. A fixed seat; B. elastic contact surface.
Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 3, the elastic mechanism for the linear cutting stapler is installed at the front end of a fixed seat a of the linear cutting stapler, and comprises a composite elastic body 2 and a quick assembling box 1. The block box 1 is installed on the fixing seat A, and is preferably fixed by adopting a glue binding mode. The composite elastic body 2 is inserted into the fast-packaging box 1, and the composite elastic body 2 can be conveniently checked into or detached from the fast-packaging box 1.
When the composite elastic body 2 is inserted into the quick-loading box 1 for operation, the positioning elastic sheet 2-2 is firstly pressed and deformed, and the angle of the positioning elastic sheet relative to the base 2-1 is reduced. When the positioning elastic sheet 2-2 reaches the positioning through groove 1-3, the positioning elastic sheet is automatically lifted, and the upper end of the positioning elastic sheet 2-2 further enters the positioning through groove 1-3 and is clamped.
The composite elastic body 2 comprises a base 2-1, a forward elastic sheet 2-3, a backward elastic sheet 2-4 and a positioning elastic sheet 2-2, wherein the positioning elastic sheet 2-2 is arranged at the front end of the base 2-1; the forward elastic piece 2-3 and the backward elastic piece 2-4 are simultaneously arranged at the rear end of the base 2-1.
The fast-assembling box 1 is installed on the fixing seat A in a glue-binding mode.
The quick-loading box 1 is a shell 1-1 with an opening at one end, and a positioning through groove 1-3 is formed in the upper end face of the shell 1-1; the upper side of the opening end of the shell 1-1 is provided with an inclined plane 1-2. The height of the inner cavity of the shell 1-1 is larger than the thickness of the base 2-1, and the installation is convenient.
The backward elastic sheets 2-4 are symmetrically arranged on the base 2-1 relative to the forward elastic sheets 2-3; the upper end surfaces B of the backward elastic pieces 2-4 and the forward elastic pieces 2-3 are positioned in the same horizontal plane, so that the elastic contact range is enlarged, and the operation stability is improved; the included angles of the backward elastic sheet 2-4 and the forward elastic sheet 2-3 relative to the horizontal plane are both 30-40 degrees, and the installation directions of the backward elastic sheet 2-4 and the forward elastic sheet 2-3 are opposite.
