Abstract
The utility model relates to the field of medical devices, and in particular relates to an anastomat. The anastomat comprises a front seat (1), an anastomat shell (2) and a linking mechanism, wherein the linking mechanism comprises a first connecting rod (3) and a second connecting rod (4); one end of the first connecting rod (3) is hinged with the front seat, one end of the second connecting rod (4) is hinged with the anastomat shell (2), and the other end of the second connecting rod (4) is hinged with the middle part of the first connecting rod (3); and the front seat (1) is also provided with a spring which can be used for returning the front seat (1) to the original state. According to the anastomat, operators require less percussion force.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of anastomat.
Background technology
Anastomat is the equipment that the alternative traditional-handwork that medically uses is sewed up.The anastomat of prior art is to adopt the link gear of lever principle to pull the trigger, namely promoting front stall moves, the link gear of prior art comprises a connecting rod, described connecting rod middle part is hinged with the anastomat shell, be that balance pivot is arranged on the anastomat shell, and described connecting rod one end also leans against on the front stall, when the pivot link other end, connecting rod has the displacement of horizontal direction, thus can promote the front stall horizontal displacement, and then so that anastomat can pull the trigger, but the percussion force that this link gear needs is larger, and the horizontal displacement of the front stall that drives after rotating of connecting rod is fewer, so that the medical worker has used for a long time is more tired, and not so good control.
Summary of the invention
Technical problem to be solved in the utility model is: the less anastomat of percussion force that a kind of needs are provided.
The technical scheme that this utility model adopts is: a kind of anastomat, comprise front stall, anastomat shell and link gear, described link gear comprises first connecting rod and second connecting rod, described first connecting rod one end and front stall are hinged, described second connecting rod one end and anastomat shell are hinged, the described second connecting rod other end and first connecting rod middle part are hinged, and also are provided with on the described front stall be used to allowing front stall be returned to former stateful spring.
Adopt above structure compared with prior art, the utlity model has following advantage: change original lever linkage structure into present connection-rod linkage mechanism, the needed percussion force of percussion anastomat has tailed off like this, namely hold the first connecting rod other end needed percussion force that makes progress less, the medical worker uses anastomat just light much like this.
As preferably, it also comprises a bumper bar, and described bumper bar and anastomat shell are hinged, and the described first connecting rod other end also is provided with the projection for spacing bumper bar.Can prevent that like this mistakenly hit from sending out.
Description of drawings
Accompanying drawing is the structural representation of this utility model anastomat.
As shown in the figure: 1, front stall; 2, anastomat shell; 3, first connecting rod; 4, second connecting rod; 5, spring; 6, bumper bar; 7, projection.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment this utility model is described further, but this utility model is not limited only to the following specific embodiment.
As shown in drawings: a kind of anastomat, comprise front stall 1, anastomat shell 2 and link gear, described link gear comprises first connecting rod 3 and second connecting rod 4, described first connecting rod 3 one ends and front stall 1 are hinged, described second connecting rod 4 one ends and anastomat shell 2 are hinged, described second connecting rod 4 other ends and first connecting rod 3 middle parts are hinged, and also are provided with on the described front stall 1 be used to allowing front stall 1 be returned to former stateful spring 5.
It also comprises a bumper bar 6, and described bumper bar 6 is hinged with anastomat shell 2, and described first connecting rod 3 other ends also are provided with the projection 7 for spacing bumper bar 6.
The operation principle of this utility model anastomat is: at first rotate bumper bar 6, the no longer spacing first connecting rod 3 of bumper bar 6 is moved up, hold afterwards first connecting rod 3 other ends, namely be provided with projection 7 those ends, the application of force makes progress, first connecting rod 3 is moved upward, because second connecting rod 4 is hinged with anastomat shell 2, so the position of that pin joint can not moved, the motion of first connecting rod 3 can drive the motion of second connecting rod 4 like this, and then drive front stall 1 and move forward, reached the purpose of percussion anastomat.
