Description
Technical field
The utility model is related to field of medical device, more particularly to a kind of Colon and rectum surgery cutter.
Background technology
When Colon and rectum surgery carries out Colon and rectum resection operation, generally Colon and rectum is accurately cut, precision will
Ask very high.But common surgical knife design is simple, without the human colorectal equipment of fixation, knot can not be fixed during cutting straight
The cut position of intestines, is often difficult to ensure the precision of surgical cut, increases operation risk.
Utility model content
The utility model is in by section mainly solving the technical problems that provide a kind of Colon and rectum surgery cutter
The telescopic cutting blade of tweezer middle setting of U-shaped, can be clamped colorectal carcinoma, then release when using using tweezer
Cutting blade carries out cutting operation to Colon and rectum, has ensured the precision of surgical cut.
To achieve the above object, the utility model provides following technical scheme：A kind of Colon and rectum surgery cutter, its
It is characterised by：The tweezer that the Colon and rectum surgery cutter takes the shape of the letter U including section, passes through at the closed end inside center of tweezer
Spring is connected with cutting blade, and spring is spiral circle cylindricality, and the diameter of spring is less than 1/3rd of tweezer inner width, cuts
The tip of cutting blade towards the openend of tweezer, length 1 to 2 cm shorter than the length of tweezer of cutting blade, cutting blade top
Center is connected with discoidal promotion button by connecting rod, promotes button to be located at the outside of tweezer.
Used as the further optimization of the technical program, the tweezer, cutting blade, connecting rod, promotion button are by the trade mark
The stainless steel making of 0Cr13.
Used as the further optimization of the technical program, the spring is manufactured by the rustproof spring steel of 3Cr13, and spring is by weldering
Connect and be fixedly connected with cutting blade and tweezer respectively.
Used as the further optimization of the technical program, the connecting rod is consolidated with cutting blade and promotion button respectively by welding
Fixed connection.
Beneficial effect using above technical scheme is：In the closed end inside of the tweezer of the Colon and rectum surgery cutter
Cutting blade is connected with by spring at the heart, discoidal promotion button is connected with by connecting rod at cutting blade top center, pushed away
Dynamic button is located at the outside of tweezer.When doing Colon and rectum surgical resection, doctor can hold the outside of tweezer with thumb and middle finger, food
Finger is pressed against on promotion button, and thumb and middle finger are exerted oneself in opposite directions, is clamped stomach tissue or intestinal tissue using tweezer, then push away
Dynamic to promote button, release cutting blade carries out cutting operation to Colon and rectum, clamps a bit of Colon and rectum with tweezer every time, just promotes and cuts
Cutting blade cuts the colorectal carcinoma of the segment, the effective guarantee precision of surgical cut.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is a kind of front view of Colon and rectum surgery cutter of the utility model；
Fig. 2 is a kind of top view of Colon and rectum surgery cutter of the utility model；
Fig. 3 is a kind of sectional view of Colon and rectum surgery cutter of the utility model.
Wherein, 1-tweezer, 2-cutting blade, 3-promotion button, 4-spring, 5-connecting rod, 6-openend, 7-closure
End.
Specific embodiment
Describe a kind of preferred embodiment of Colon and rectum surgery cutter of the utility model in detail below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 and Fig. 3 show a kind of specific embodiment of Colon and rectum surgery cutter of the utility model：The knot is straight
The tweezer 1 that enterochirurgia cutter takes the shape of the letter U including section, is connected with by spring 4 at the inside center of closed end 7 of tweezer 1 and cut
Cutting blade 2, as shown in Fig. 2 spring 4 is spiral circle cylindricality, and the diameter of spring 4 is less than 1/3rd of the inner width of tweezer 1,
Ensure that the openend 6 of tweezer 1 can be kneaded together.The tip of cutting blade 2 towards the openend 6 of tweezer 1, cutting blade 2
Length 1 to 2 cm shorter than the length of tweezer 1, the elongation length most long of spring 4 is more than 2 cm.Lead at the top center of cutting blade 2
Cross connecting rod 5 and be connected with discoidal promotion button 3, promote button 3 to be located at the outside of tweezer 1, cutting can be driven by promoting button 3
Blade 2 is slided.
With reference to Fig. 1, Fig. 2 and Fig. 3, tweezer 1, cutting blade 2, connecting rod 5, promotion button 3 are the stainless steel of 0Cr13 by the trade mark
Manufacture, it is sturdy and durable, and good corrosion resistance, long service life.Spring 4 is manufactured by the rustproof spring steel of 3Cr13, and spring 4 passes through
Welding is fixedly connected with cutting blade 2 and tweezer 1 respectively, connection fastening, not easy to break.Connecting rod 5 by welding respectively with cutting
Blade 2 and promotion button 3 are fixedly connected.
When doing Colon and rectum surgical resection, doctor can hold the outside of tweezer 1 with thumb and middle finger, and forefinger is pressed against and pushes away
On dynamic button 3, thumb and middle finger are exerted oneself in opposite directions, are clamped colorectal carcinoma using tweezer 1, then promote button 3, and release is cut
Cutting blade 2 carries out cutting operation to Colon and rectum, clamps a bit of colorectal carcinoma with tweezer 1 every time, just promotes cutting blade 2 to cut
Cut the colorectal carcinoma of the segment, the effective guarantee precision of surgical cut reduces the risk of operation.
The above is only preferred embodiment of the present utility model, it is noted that for one of ordinary skill in the art
For, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
