Description
Technical field
The utility model relates to medical instruments fields, are specifically related to a kind of surgical scissors.
Background technique
With the popularization and application of plastics biliary tract rack under scope, according to the actual situation, it is sometimes desirable to human body chamber will be trapped in
Extra plastic stent cuts off and takes out in road, retains stent length appropriate, to play the role of drainage.Currently, market
In have CN201220479340.3- for shear under scope the device (Zhang Shi scissors) of plastic catheter can complete bracket cutting it is dynamic
Make.But in conjunction with clinical use, find the scissor blade due to design reasons, scissors start every time cut pipe when, blade
The contact length of cutting edge and pipe is bigger, and the pressure acted on tube wall on each point is smaller, it is difficult to tube wall occur broken
It splits and cuts off pipe, or elliptical shape is presented in the section of pipe after pipe is cut off, and reduces the effect of drainage.
Utility model content
In order to overcome the drawbacks of the prior art, the utility model proposes a kind of operations with special shape cutting blade
Scissors, make to cut every time pipe when, blade and the incipient contact length very little (about 0.15mm) of tube wall, similarly to act on
When power is acted on tube wall, the pressure on contact point is very big, makes tube wall be easier to rupture, and then continuously cut tube wall.
The utility model is realized in this way:
The utility model provides a kind of surgical scissors comprising tool apron, blade and drag-line are provided with shaft on tool apron
Pin, what blade was able to rotate is assemblied in the roller pin of tool apron, and the blade can surround the roller pin by means of the drag-line
It is rotated to obtain cutting action；
The middle position of the blade is provided with taper spur, and the taper spur is configured to when cutting action starts
It is in contact to form powerful pressure and rupture tube wall with pipe fitting at first；
The second end of the tool apron, which is provided with, to cut line groove, and described cut line groove is configured to scope incision breaking joint zygonema.
Preferably, the second end of the tool apron is set as duckbill.
Preferably, the first end of the tool apron is connected with bourdon tube.
Preferably, the blade is respectively arranged with straight cutting edge and declivous cutting edge in the two sides of the taper spur.
Preferably, what the side of the tool apron and the blade contact was provided with arc cuts nose bile duct slot, the tool apron with
The separate side of the blade, which is provided with, allows empty slot.
Compared with prior art, the utility model has the following beneficial effects:
A taper spur is arranged at the intermediate position of this blade cutting edge in the utility model, equally outputs cutting edge；Often
When secondary cutting starts, the cutting edge of taper spur is contacted with tube wall first, the state for being similar to point contact is formed, in this way, blade exists
Spinning movement occurs under the external force that operation portion applies, tube wall is easy under the powerful pressure action of the upper conical spur of blade
It ruptures and is continuously cut.
Detailed description of the invention

Specific embodiment
The exemplary embodiment, feature and aspect of the utility model are described in detail below with reference to attached drawing.It is identical in attached drawing
Appended drawing reference indicate element functionally identical or similar.Although the various aspects of embodiment are shown in the attached drawings, remove
It non-specifically points out, it is not necessary to attached drawing drawn to scale.
As shown in Figure 1, the utility model provides a kind of operating scissors comprising tool apron 1, blade 2 and drag-line 3, drag-line 3 with
Blade 2 connects, and the first end 1001 of tool apron 1 is provided with bourdon tube, roller pin 101 is provided on tool apron 1, what blade 2 was able to rotate
It is assemblied in the roller pin 101 of tool apron 1, drag-line 3 applies active force to blade 2 under the action of operation portion, enables blade 2
It is rotated around roller pin 101, obtains cutting action.
07F in Fig. 1 and Fig. 2,10F represent the caliber of nose bile duct, the utility model be suitable for now widely used 06F,
The nose bile duct of 07F, 08F, 09F, 10F diameter is cut.
To obtain good cutting effect, as shown in figure 3, the intermediate suitable position in blade 2 is provided with taper spur
202, it is in contact at first with pipe fitting when cutting action starts taper spur 202, forms powerful pressure and rupture tube wall,
And then continuous cutting tube wall is until pipe disconnects.Blade 2 the two sides of taper spur 202 be respectively arranged with straight cutting edge 201 and tiltedly
Cutting edge 203.Straight cutting edge 201 and declivous cutting edge 203 are separately positioned on the two sides of taper spur, and the setting of declivous cutting edge 203 is in distal end, straight sword
