Abstract
The invention discloses an incision expander for a pleuroperitoneal cavity operation, which includes a left half body, a right half body and a double-hole connecting piece, wherein the right half body includes a right half body front assembly and a right half body rear assembly; the left half body, the right half body and the double-hole connecting piece form a controllable four connecting-rod structure by four pin shafts; the shape of the four connecting-rod structure can be changed when a handle is pressed, and the four connecting-rod structure is stable when shaped like a triangle, and an expansion piece for connecting the left half body and the front side of the right half body front assembly is at the maximum opening degree at the time. The incision expander has the automatic locking and closing functions, can be opened or locked when a surgeon exerts pressure, and can be closed when the surgeon continues to exert pressure, so that the operation is very convenient; the structure is simplified, the production cost is reduced, cooperation of all parts is reasonable, tiny parts are not involved, and the service life is long.
Description
Technical field
The present invention relates to medical apparatus and instruments aid technical field, particularly a kind of splanchnocoel operation incision expander that can open and automatically locate.
Background technology
Conventionally, the dilator using in laparoscopically surgical operation or other surgical operation has the function of some mechanical grasping tissues or body part, for example clamp, finger or hook.Laparoscopically surgical operation instrument must insert be formed at endoceliac compared with in microstome.The diameter in these apertures is between 5mm and 12mm.When using manipulator, clamp etc. are conventionally quite little, and they can be inserted through aperture.Therefore, manipulator will be quite little at the surface area at their grasping end place, and this causes the sizable stress to body part at grasping end place.This may cause the accident trauma of body part or tear.And in the situation that or not forming larger otch in health, larger laparoscopic apparatus is difficult to or can not insertosome intracavity.
By retrieval, find, existing dilator fixed form is unreasonable, causes inconvenient operation, even needs nurse's auxiliary operation.For example, existing dilator must arrange and regulate and locking mechanism, mostly adopts bolt-locking and adjusting, or regulates fitted bolt to lock by gear.Structure member is complicated, and the increase doctor operational ton of operation process is cumbersome.
Summary of the invention
The object of the invention is to overcome existing dilator because the problem and shortage that structural design exists causes unhandy problem, a kind of flexible operation, splanchnocoel operation incision expander are easily provided.
Technical scheme: a kind of splanchnocoel operation incision expander, comprise left halfbody and right halfbody, and expanding plate, described left halfbody is respectively arranged with axis hole A ' and axis hole B '; Described right halfbody comprises assembly after right halfbody front assembly and right halfbody; Described right halfbody front assembly is provided with axis hole B " and C ", axis hole C " be bar shaped axis hole; After described right halfbody, assembly is provided with axis hole C ' and D '; Also be provided with diplopore contiguous block, diplopore connecting hole is respectively arranged with axis hole A " and axis hole D ".
Described axis hole A ' and axis hole A " by bearing pin A, link together; Described axis hole B ' and axis hole B " by bearing pin B, link together; Described axis hole C ' and axis hole C " by bearing pin C, link together; Described axis hole D ' and axis hole D " by bearing pin D, link together;
After the rear end of described left halfbody and right halfbody, the rear end of assembly is respectively arranged with handle.
The front end of the front end of described left halfbody and right halfbody front assembly is respectively arranged with support arm one and support arm two; Described support arm one and support arm two are fixed with respectively left and right expanding plate, and left and right two expanding plate make-ups form borehole structure.
In the front end inner side of described left halfbody and the front end inner side of right halfbody front assembly, be respectively arranged with spring base and be set with spring.
Described support arm one and support arm two, be respectively length-adjustable support arm.
Beneficial effect of the present invention: follow-on dilator, there is auto lock and automatic closing function, operative doctor only need provide pressure can make dilator open and lock, and continues to provide pressure can make dilator in closure, and operation is very easy.This structure is relatively simplified, and reduces production costs, and each parts coordinate rationally, non-tiny parts, long service life.Have two kinds of structures of fixed pattern and adjustment type, the dilator of adjustment type can extend support arm and expand support angle.The present invention has simple in structure, reasonable in design, and the advantage that result of use is good is beneficial to promotion and implementation very much.

the specific embodiment
Embodiment 1: a kind of splanchnocoel operation incision expander, and referring to Fig. 1, Fig. 2 and Fig. 3, left halfbody 1 is respectively arranged with axis hole A ' and axis hole B '; Right halfbody comprises assembly 3 after right halfbody front assembly 2 and right halfbody; Right halfbody front assembly 2 is provided with axis hole B " and C ", axis hole C " be bar shaped axis hole; After right halfbody, assembly 3 is provided with axis hole C ' and D '; Also be provided with diplopore contiguous block 4, diplopore connecting hole 4 is respectively arranged with axis hole A " and axis hole D ".
Described axis hole A ' and axis hole A " by bearing pin A, link together; Described axis hole B ' and axis hole B " by bearing pin B, link together; Described axis hole C ' and axis hole C " by bearing pin C, link together; Described axis hole D ' and axis hole D " by bearing pin D, link together;
After the rear end of left halfbody 2 and right halfbody, the rear end of assembly 3 is respectively arranged with handle 5.The front end of the front end of left halfbody 1 and right halfbody front assembly 2 is respectively arranged with support arm 1 and support arm 27; Support arm 1 and support arm 27 are fixed with respectively left and right expanding plate 8, and left and right two expanding plate 8 make-ups form borehole structure.
And, in the front end inner side of described left halfbody 1 and the front end inner side of right halfbody front assembly 2, be respectively arranged with spring base 9 and be set with spring 10.
Referring to Fig. 4-Fig. 7, represent respectively the different tensioner degree of dilator, in figure, exist common constant amount to be: the constant h that is always of AB segment length, αHe angle, angle γ is fixed value.
As can be seen from Figure 4, before compression two handles 5, under spring 10 effects, the opening angle of dilator is less, distance m between two handles 5
2, distance n between two expanding plates 8
2, the tetragon that ABCD forms is convex quadrangle.
As can be seen from Figure 5, after starting compander handle 5, between two handles 5, Distance Shortened is m
1, between two expanding plates 8, distance also starts to be increased to n
1, the tetragon that ABCD forms is convex quadrangle.
As can be seen from Figure 6, when compander handle 5 to a certain extent after, between two handles 5, distance further shortens to m
0, the tetragon that ABCD forms forms the relatively stable structure of ABC triangle because AD and CD are located on the same line, the air line distance in this structure between A and C is the longest, makes the right halfbody front assembly of DC section to the limit, thereby between two expanding plates 8 distance the longest be n
0, dilator can automatically not open or compress, in rock-steady structure.Wherein, axis hole C " be bar shaped axis hole, can meet bearing pin C front and back slip needs.
As can be seen from Figure 7, if more further between handle 5, two handles 5 of compander distance further shorten to m
-1, the tetragon that now ABCD forms is recessed tetragon, DC section starts drag right halfbody front assembly and moves backward, axis hole C " be bar shaped axis hole, can meet bearing pin C front and back slip needs, thereby the distance between two expanding plates 8 starts to be again reduced to n
-1, dilator labile state now, this state is applicable to after hours, can take off flexibly dilator.Practical situation is m
2> m
1> m
0> m
-1; n
0> n
-1, n
