Description
Technical field
The utility model relates to area of medical devices.
Background technique
Gastrointestinal surgery is the specific clinics based on diagnosis and treatment gastrointestinal disease, stomach and intestine tumor, and operating scissors are in gastrointestinal surgery
One very high surgical instrument of frequency of use carries out switching action by manpower when in use, in some cases,
The case where scissors is maintained at feature is needed when use, it is not only unstable if being kept with hand, but also be easy tired
Labor.
Currently, clinically when carrying out gastrointestinal surgery to patient used operating scissors mainly by finger ring, cut arm, connection
Axis and shear blade are constituted, in order to fix its shape, as shown in Fig. 1, by finger ring relative to being connected with fixed arm, fixed arm
It is fixed by mutually blocking.This mode secures to a certain extent, but since the length of fixed arm is smaller, too long
If can interfere between each other, fix locational space it is limited, when having certain amplitude opening such as scissors, can not fix,
And this fixed form is unstable, is easy to open.
Utility model content
The purpose of this utility model is that: in view of the above problems, a kind of gastrointestinal surgery is provided and is cut, including
One cuts and second cuts handle, and described first, which cuts handle and second, cuts hingedly forming, and first, which cuts handle and second, cuts handle and be equipped with
Finger ring, which is characterized in that described first is cut being above fixedly connected with curved rod, and second cuts and passed through for curved rod being equipped with
First passage, second, which cuts the finger ring inner wall of handle and channel bracket, is equipped with second channel, and fixed column is equipped in second channel, fixed
Column can be contacted with curved rod, and fixed column is equipped with teeth portion, and curved rod is equipped with friction block, and teeth portion and friction block contact restriction arc
The arc core of the rotation of shape bar, curved rod is cut second the hinged place for cutting handle with second.
In the present invention, operating scissors open or be closed into need fixed when, with finger push fixed column,
The friction block of teeth portion and curved rod in fixed column contacts, and the shearing force that curved rod is certain to fixed column, leads to fixed column
When the mutual lever of column can be further fixed, and then the deployed position of operating scissors is fixed, but need to unclamp, with pulling
Fixed column out.
When in use, for the convenience of finger push fixed column, one end that the fixed column is located at finger ring is equipped with
Button, button facilitate finger to pin, and button and fixed column integrated molding or connect firmly.
In order to enable fixed column preferably fixes curved rod, fixed column and curved rod cut handle far from first towards curved rod
Direction inclination, tilt angle are generally 5-10 degree, preferably 5 degree, and fixed column is more preferable to the fixed effect of curved rod, will not produce
Raw mutually sliding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of fixed column and curved rod；
Fig. 3 is the schematic diagram of fixed column and curved rod；
Marked in the figure: 1- first cuts handle, 101- curved rod, 1011- friction block, 2- second cuts handle, 201- fixed column,
2011- teeth portion, 2012- button, the channel 202-.
Specific embodiment
Specific embodiment 1: present embodiment discloses a kind of gastrointestinal surgeries to cut, including first cuts 1 and second are cut
It cuts handle and second 2, described first to cut and hingedly form 2, first, which cuts handle and second, cuts finger ring is equipped with, and feature exists
In described first cuts being fixedly connected with curved rod 101 on 1, and second cuts and lead to first passed through for curved rod is equipped with
Road 202, second cuts the finger ring inner wall of handle and channel bracket equipped with second channel 203, and second channel is interior to be equipped with fixed column 201, Gu
Fixed column can be contacted with curved rod 101, and fixed column is equipped with teeth portion 2011, and curved rod is equipped with friction block 1011, teeth portion and rubs
The rotation of cleaning block contact limitation curved rod, the arc core of curved rod are cut second the hinged place for cutting handle with second.The fixation
One end that column is located at finger ring is equipped with button 2012, and button facilitates finger to pin.Fixed column and curved rod are towards curved rod far from
One cuts the direction inclination of handle.
