Background technology
Surgical scissors is one of indispensable important apparatus in current surgeon's surgical work, especially needs the surgical patients of operative treatment; But present surgical scissors is because by not easily opening after cutting again, but some can open two blades with the shears of shell fragment class can not regulate the dynamics of opening, operate uncomfortable, nor its length can be regulated, and shearing blade is all flat sword, do not cut the thing that some hardness are higher, for this, it is proposed that a kind of Medical surgical shears.
Summary of the invention
It is an object of the invention to provide a kind of Medical surgical shears, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of Medical surgical shears, including two shear blades, two shear blades are arranged in a crossed manner, and the crossover location of two shear blades is connected by bearing pin, the side that two shear blades are relative is equipped with blade, described blade includes flat sword and land, described flat sword is near the tip of shear blade, described shear blade is provided with connecting rod away from one end of tip, described connecting rod is connected to adjusting rod away from one end of shear blade, the side that two adjusting rods are relative is equipped with the first chute, described first chute is provided with slide block, the front side of described adjusting rod is additionally provided with the second chute, described second chute runs through and is provided with fixing screw, and fixing screw threadeds with the screw of slide block side, and the relative side of two slide blocks connects by compressing spring, described adjusting rod is connected to expansion link away from one end of connecting rod, described expansion link is provided with semicircular hand-held ring away from the one end side of adjusting rod.
Preferably, described expansion link is provided with link away from one end of adjusting rod.
Preferably, described expansion link includes bar set, and the inside of described bar set is provided with interior bar, and the opening of one end bar set of interior bar and extend to the outside of bar set, and the end of described interior bar connects adjusting rod, runs through being provided with trip bolt in the opening side of bar set.
Preferably, the one end side that described interior bar is located within bar set is provided with the first spacing ring, and the opening inwall of described bar set is provided with the second spacing ring.
Preferably, the side end that two adjusting rods are relative is equipped with protection block, and two protection blocks are corresponding.
Compared with prior art, the invention has the beneficial effects as follows: this Medical surgical shears, it is possible to make two blades of shears have tension force after cutting thing, it is easy to open, and the dynamics opened can be regulated, operating comfortable, the adjusting rod of shears is connected to expansion link, it is possible to adjust the length of shears, and blade includes flat sword and land, both concordant interface can be cut by flat sword, it is also possible to cut the more difficult thing cut, convenient use by land.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1-2, the present invention provides a kind of technical scheme: a kind of Medical surgical shears, including two shear blades 1, two shear blades 1 are arranged in a crossed manner, and the crossover location of two shear blades 1 is connected by bearing pin 2, the side that two shear blades 1 are relative is equipped with blade 3, blade 3 includes flat sword 31 and land 32, flat sword 31 is near the tip of shear blade 1, both can pass through flat sword 31 and cut concordant interface, land 32 can also be passed through and cut the more difficult thing cut, convenient use, shear blade 1 is provided with connecting rod 11 away from one end of tip, connecting rod 11 is connected to adjusting rod 5 away from one end of shear blade 1, the side that two adjusting rods 5 are relative is equipped with the first chute 6, first chute 6 is provided with slide block 7, the front side of adjusting rod 5 is additionally provided with the second chute 8, second chute 8 runs through and is provided with fixing screw 9, and fixing screw 9 threadeds with the screw of slide block 7 side, the position of slide block 7 can be fixed by fixing screw 9, and the relative side of two slide blocks 7 connects by compressing spring 10, the tension force of compression spring 10 can be adjusted by the slide block 7 slip in the first chute 6, operate comfortable, easy to use, the side end that two adjusting rods 5 are relative is equipped with protection block, and two protection blocks are corresponding, by protecting block to be possible to prevent, the compression of compression spring 10 is exceeded its normal deformation range, compression spring 10 can be protected, adjusting rod 5 is connected to expansion link 4 away from one end of connecting rod 11, expansion link 4 includes bar set 41, the inside of bar set 41 is provided with interior bar 42, and the opening of one end bar set 41 of interior bar 42 and extend to the outside of bar set 41, the end of interior bar 42 connects adjusting rod 5, interior bar 42 overlaps at bar and slides in 41 thus the length of adjustable telescopic rod 4, thus regulating the length of shears, run through in the opening side of bar set 41 and be provided with trip bolt 43, interior bar 42 can be fixed, interior bar 42 is located at bar set one end side within 41 and is provided with the first spacing ring 44, the opening inwall of bar set 41 is provided with the second spacing ring 45, two spacing rings are possible to prevent interior bar 42 to skid off from bar set 41, expansion link 4 is provided with semicircular hand-held ring 13 away from the one end side of adjusting rod 5, convenient use, expansion link 4 is additionally provided with link 12 away from one end of adjusting rod 5, it is easy to the folding and unfolding of shears, use comfort and convenient.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, being appreciated that and these embodiments can be carried out multiple change, amendment, replacement and modification without departing from the principles and spirit of the present invention, the scope of the present invention be defined by the appended.
