Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of puncture outfit being easy to skin histology removing as shown in Figure 1 and Figure 2, including sheath assembly 2 and it is interspersed in casing
Puncture needle 1 in component 2, the puncture needle 1 include the reach bar portion 1-1 and puncture portion 1-2 with reach bar portion 1-1 integral structure,
The puncture portion 1-2 is tool there are four the flat four seamed edges duckbill structure of the conical surface, and four conical surfaces connect to be formed four
In seamed edge, being located at corresponding two seamed edges of width direction is camber line 1-3, and being located at corresponding two seamed edges of thickness direction is straight line 1-
4。
The puncture portion top 1-2, equipped with the air discharge duct 3 for starting from four conical surface upper ends and extending to reach bar portion 1-1, convenient for wearing
Thorn Shi doctor can hear that exhaust sound prompts in human abdominal cavity, controls paracentesis depth.
The puncture portion 1-2 on 1 head of puncture needle is designed to four flat seamed edge duckbill structures, more by the utility model
Surgical is facilitated to puncture.Doctor is inserted into puncture outfit by the osculum opened on human skin in puncture process, holds puncture
1 tail end of needle, so that puncture portion 1-2 is rotated left and right, the such puncture portion 1-2 flat conical surface can be quickly accomplished skin histology
Removing, procedure efficiency is improved, and surgical wound is also smaller.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
