The ejection structure comprises a sleeve and a handle, wherein the front end of the handle is hinged with the sleeve. The ejection structure further comprises a connecting rod, wherein one end of the connecting rod is hinged with a housing of the anastomat/stitching instrument and while the other end of the connecting rod is hinged with an intermediate section of the handle.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of pushing and withstanding structure of kissing cutter in the stiching instrument.
Background technology:
Endless knife is armarium commonly used in the modern medical service process, and it excises incidence tissue by endless knife.In the existing kiss stiching instrument, cutter is carried out the top is realized by operating grip, the front end of operating grip is hinged with the sleeve pipe that is enclosed within on the displacement screw mandrel, and at the middle part of handle another pin joint is set, and this pin joint is hinged with the shell of kiss stiching instrument, like this, this handle just forms lever construction, realizes advancing of sleeve pipe or retreats by pressing handle, and then realize operation to cutter, but the operating grip of lever construction was relatively required great effort in actual time, was not easy to operation.
The utility model content:
For solving above-mentioned technical problem, it is a kind of simple in structure that this utility model provides, and is easy to install the pushing and withstanding structure of cutter in its kiss stiching instrument easy and simple to handle.
The technical solution of the utility model is, a kind of pushing and withstanding structure with kiss stiching instrument cutter of following structure is provided, it comprises sleeve pipe and handle, front end and the sleeve pipe of described handle are hinged, it also comprises connecting rod, one end of described connecting rod is hinged with kiss stiching instrument shell, and the stage casing of the other end and handle is hinged.
After adopting said structure, the utlity model has following advantage:
Between operating grip and kiss stiching instrument shell, increase connecting rod, change the lever construction of original operating grip into plane four side rod mechanisms, can significantly reduce like this operation firmly, it is comparatively laborsaving when cutter is operated, and utilize the stability of plane four side rod mechanisms, can make the work of cutter more stable.
Description of drawings:
Fig. 1 is the schematic diagram of the pushing and withstanding structure of this utility model kiss stiching instrument cutter;
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the pushing and withstanding structure of this utility model kiss stiching instrument cutter, it comprises sleeve pipe 2 and handle 1, the front end of described handle 1 and sleeve pipe 2 are hinged, main inventive point of the present utility model is to change the lever structure of original handle into four-bar linkage structure, concrete: it also comprises connecting rod 3, and an end of described connecting rod 3 is hinged with kiss stiching instrument shell 4, and the stage casing of the other end and handle 1 is hinged.Like this, handle 1 is comparatively laborsaving and more stable when operation.
