Specific embodiment:
Embodiment: below embodiments of the present invention are illustrated by particular specific embodiment, those skilled in the art can be by
Content disclosed in the present specification understands other advantages and effect of the present invention easily.
As shown in Figure 2, a kind of mosquito forcepss, comprising: the first caliper 10, it includes integrally formed one first clamping part 11 He
One first linking arm 12;Second caliper 20, it is hinged with described first caliper 10, and described second caliper 20 includes being integrally formed
One second clamping part 21 and one second linking arm 22;Described second clamping part 21 is matched with described first clamping part 11 and is combined into
For clamping the clamp head part of blood vessel;First clamp handle 30, it includes integrally formed one first adjusting tap 31 and one first grip part
32, described first clamp handle 30 is connected with described first caliper 10 by described first adjusting tap 31;And second clamp handle 40, its bag
Include integrally formed one second adjusting tap 41 and one second grip part 42, described second clamp handle 40 passes through described second adjusting tap 41
It is connected with described second caliper 20;Wherein, the free end of described first linking arm 12 and described second linking arm 22 molding respectively
There are some adjustment holes 60;Described first adjusting tap 31 and described second adjusting tap 41 are hollow structure, described first adjusting tap 31
It is respectively arranged with the adjusting screw 50 matching with described adjustment hole 60 with described second adjusting tap 41;See Fig. 2 and Fig. 3 institute
Show, described first clamping part 11 and described second clamping part 21 form teeth portion 70 respectively, described teeth portion 70 is molded over described
The upper and lower of the clamping face of the first clamping part 11 and described second clamping part 21, described first clamping part 11 and described second
The middle part of the clamping face of clamping part 21 forms a concave part 80.
As shown in Figure 2, it is provided with a position-limiting unit 90, described limit between described first clamp handle 30 and described second clamp handle 40
Bit location 90 includes that one end is fixedly installed on described second adjusting tap 41, the other end runs through the arc of described first adjusting tap 31
Part 91 and the block 92 being molded over described arcuate member 91 end, wherein, described first adjusting tap 31 form for described arc
The through hole that part 91 wears, described block 92 is fixedly installed on the end of described arcuate member 91, if forming on described arcuate member 91
Dry etching trace.The function of described position-limiting unit 90 is that described first clamp handle 30 and described second clamp handle 40 link together, when need
When wanting the length that modulating hemostasis clamp, described first adjusting tap 31 and described second adjusting tap 41 can be moved simultaneously, and need not be single
Individual movement, easy to use.In addition, described position-limiting unit 90 also acts as described first linking arm 12 of restriction and described second connection
