A ring shaped stopper is additionally provided with pin and ring shaped stopper is located at the bottom of spring.
Further, a lifting hand is provided with the top of the three-edged needle.
Further, the ring shaped stopper be located in guide pin pipe and have a diameter larger than through hole and guide pin ttom of pipe stomidium it is straight
Footpath.
Further, the spring outer diameter is less than through hole and ring shaped stopper diameter.
Further, the ring shaped stopper screw thread is rotatably connected on three-edged needle and ring shaped stopper can be adjusted by turn three
Position on rib pin.
(3) beneficial effect
The utility model has the advantages that relative to prior art：
A kind of blood-letting puncture assistor that the utility model is mentioned, it can make it that the power that blood-letting puncture is pierced into every time and depth are
It is fixed horizontal, it is ensured that each operator can safety and specification execution blood-letting puncture therapy, while can be according to passing through choosing
Lower needle force road is adjusted with different springs, can also select to adjust ring shaped stopper deep to adjust lower pin in the position on three-edged needle
Degree, it is easy to operate.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
A kind of blood-letting puncture assistor as shown in Figure 1, including half arc ball cover 1 and three-edged needle 2, the top of the half arc ball cover 1
Portion center is provided with a through hole 11, and the inner side of half arc ball cover 1 is installed with one and through hole 11 in the corresponding position of through hole 11
Concentric guide pin pipe 3, the bottom position of the guide pin pipe 3 are provided with a seam step 31, and the three-edged needle 2 is arranged in through hole
11 and guide pin pipe 3 in, a spring 4 being sheathed on three-edged needle 2 is provided with guide pin pipe 3, a ring is additionally provided with three-edged needle 2
Shape block 21 and ring shaped stopper 21 are located at the bottom of spring 4.
Wherein, the top of the three-edged needle 2 is provided with a lifting hand 22；The ring shaped stopper 21 be located in guide pin pipe 3 and
Have a diameter larger than through hole 11 and the diameter in the bottom hole of guide pin pipe 3；The external diameter of spring 4 is less than through hole 11 and ring shaped stopper 21
Diameter；The screw thread of ring shaped stopper 21 is rotatably connected on three-edged needle 2 and ring shaped stopper 21 can be adjusted by turn on three-edged needle 2
Position.
A kind of blood-letting puncture assistor that the utility model is mentioned, it is installed to whole device when specifically used first,
Just three-edged needle 2 is inserted at the lower end seam step 31 of guide pin pipe 3 first when mounted, ring shaped stopper 21 is then threaded to Rhizoma Sparganii
The middle part of pin 2, spring 4 is set on three-edged needle 2, then guide pin pipe 3 is installed on to the inside bottom of half arc ball cover 1, finally
Lifting hand 22 is fixed to the top of three-edged needle 2, installation.
When specifically used, the assistor is held, pulls up lifting hand 22 so that spring 4 is compressed completely, and half arc ball cover 1 is put
The position for needing to carry out blood-letting puncture operation is placed in, for the ease of seeing blood-letting puncture position clearly, half arc ball cover 1 can use transparent or semitransparent
Material is made to be formed, and then unclamps lifting hand 22, and three-edged needle 2 carries out lower thorn to the corresponding position of patient under the effect of spring 4, pierced
The power entered is related with the coefficient of elasticity of spring, and completion of falling every time, ring shaped stopper 21 and stopping table on three-edged needle 2
Rank 31 is bonded, the downstream end of three-edged needle 2, thus the depth of lower pin is relevant in the position on three-edged needle 2 with ring shaped stopper 21, thus
Lower needle force road can be adjusted by using different springs instead, while can also be by adjusting ring shaped stopper 21 on three-edged needle 2
Position adjustment under pin depth, be embodied as, spring is bigger, and lower needle force degree is bigger, and ring shaped stopper 21 is closer to three
The needle position of rib pin 2, the depth of lower pin are more shallow.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design conception is not departed from, ordinary people in the field couple
