Puncture process can fix, the internal medicine puncture needle of the physical strength for saving puncture personnel.
The purpose of this utility model is reached by following technical measures: a kind of internal medicine puncture needle, including needle body,
Needle body is cylindrical shape, it is characterised in that: one end of the needle body is equipped with fluid aspirator, and needle body is fixedly installed close to the inner wall of fluid aspirator
There is connecting rod fixed mount, the connecting rod fixed mount is connected with chassis, and the chassis is socketed with connecting rod, and the connecting rod passes through fluid aspirator
One end is connected with syringe needle, and the connecting rod other end is connected with limit base, and the connecting rod sleeve is connected to spring.
A kind of improvement as above-mentioned technical proposal: the spring one end is fixed on syringe needle, and other end fixation is set
It sets on chassis, spring is in compressive state always.Spring in compressive state, connecting rod drives syringe needle when avoiding not used
It shakes.
A kind of improvement as above-mentioned technical proposal: the outer wall of the needle body is equipped with several fixed pins, the fixed pin
Helical arrangement.It is screw-inserted into during needle body insertion patient, fixed pin is inserted into patient body in insertion process.
A kind of improvement as above-mentioned technical proposal: the fluid aspirator and needle body are detachably connected setting, set on fluid aspirator
There are several logical liquid baths.Logical liquid bath avoids thick hydrops from blocking fluid aspirator, and fluid aspirator is detachably connected, convenient to carry out to fluid aspirator
Cleaning.
A kind of improvement as above-mentioned technical proposal: the needle body is fixedly connected with fixing seat far from one end of fluid aspirator,
The fixed pin is fixed at close to one end of fixing seat.
A kind of improvement as above-mentioned technical proposal: the fluid aspirator is in truncated cone-shaped, fluid aspirator bottom surface diameter and needle body
Diameter is identical, and upper bottom surface diameter is identical as the side diameter that syringe needle is adjacent, between fluid aspirator and syringe needle and needle body smooth outer surface,
Avoid hurting muscle, the tissue of patient.
A kind of improvement as above-mentioned technical proposal: the limit base outer diameter is greater than the internal diameter on chassis, limit
Seat plays the role of limit, and connecting rod is avoided to be detached from chassis.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that: syringe needle and needle body it
Between installed fluid aspirator additional, the hydrops of patient's body is flowed into needle body by the logical liquid bath on fluid aspirator, avoids syringe needle blocking, needle
Body is equipped with fixed ring, and fixed ring is inserted into the patient, avoids needle body during extracting hydrops and is not fixed firmly, causes to take out
Hydrops is taken to fail.
The connecting rod is socketed with spring, generates buffering, avoids the injury in syringe needle insertion process to tissue.Fluid aspirator
It is detachably connected with needle body, facilitates medical personnel to fluid aspirator disassembly, cleaning.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
