The puncture needle of size.
Utility model content
The purpose of the utility model is to provide a kind of puncture cannulas that converter is arranged, so as to be suitable for different sizes
Puncture needle.
To achieve the goals above, the technical solution adopted in the utility model is:
It is a kind of be arranged converter puncture cannula, including one end be arranged opening the other end be wholely set the casing of seal chamber with
And it is mounted on the converter of sealing resonator end surface；The section of seal chamber is greater than the section of casing, sets gradually cylinder inside seal chamber
The liner of shape, for fixed-bearing and the cylinder-shaped pressing sleeve of end setting block machine, pressing sleeve top setting are opened round-meshed close
Packing；The lower end setting of the liner can control the symmetrically arranged inclined plate of liner lower end opening and closing, and the top of seal chamber is by setting
Set the seal cap covering of opening；Converter include tool there are two fix the integrally formed U-shaped support frame of section and a linkage section with
And the conversion insertion tube through linkage section, fix the clamp of the medial surface setting protrusion of section；The end setting of seal chamber is for the same as card
The flange of head cooperation.
Technical solutions of the utility model further improvement lies in that: be threadedly coupled between seal cap and seal chamber.
Technical solutions of the utility model further improvement lies in that: the input end for converting insertion tube is close by the rubber of setting circular hole
Sealing cap covering.
Technical solutions of the utility model further improvement lies in that: conversion insertion tube be circle, convert the diameter of insertion tube as 4mm
~10mm.
By adopting the above-described technical solution, the technical effect that the utility model obtains has:
The utility model expands the use scope of the puncture cannula, improves the puncture cannula by setting converter
Service performance.
Converter structure in the utility model is simple, and the clamp of U-shaped support frame and the flange cooperation of seal cap being capable of spirits
Work easily carries out assembling cooperation with the main body of puncture cannula.
The utility model is easy to use, easily operated.The good seal performance of the utility model can guarantee puncturing operation
It goes on smoothly.The utility model use scope is wide, and comprehensive service performance is good.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the utility model:
The utility model discloses a kind of puncture cannula that converter is arranged, which is in abdominocentesis operation
It uses, is usually used cooperatively with puncture needle.By the way that converter is arranged, which can be from different size model numbers
Puncture needle cooperation.Here is specific embodiment:
The puncture cannula of setting converter in the utility model, is to carry out on the basis of existing puncture cannula into one
It walks improved.As shown in Figure 1 and Figure 2, the other end that is open is arranged including one end to be wholely set the casing 3 of seal chamber 1 and be mounted on
The converter 2 of 1 end face of seal chamber.The section of seal chamber 1 therein is greater than the section of casing 3, sets gradually inside seal chamber 1
It is columnar to pad 4, for fixed-bearing 4 and the cylinder-shaped pressing sleeve 6 of end setting block machine.On 6 top of pressing sleeve, setting is provided with circle
The gasket 5 in hole；The lower end of liner 4 is wholely set the symmetrically arranged inclined plate 7 that can control the opening and closing of 4 lower ends of liner, pads 4
Material is usually silica gel, and the material of inclined plate 7 is also silica gel.Inclined plate 7 can guarantee airtightness in this way, while when puncture needle passes through
It can be with smooth opening.The top of seal chamber 1 in the utility model is covered by the seal cap 8 of setting opening, and the setting of opening is
In order to enable puncture needle to pass through.The top of seal chamber 1 is covered by the seal cap 8 of setting opening, common seal cap 8 and sealing
It is threadedly coupled between chamber 1, facilitates and dismounted.
As shown in figure 3, converter 2 is usually to include U-shaped support frame 2-1 and conversion insertion tube 2-2.U-shaped support frame therein
2-1 has integrally formed two fixing section 2-1-1 and a linkage section 2-1-2；And converting insertion tube 2-2 is supported across U-shaped
The linkage section 2-1-2 setting of frame 2-1.In the clamp 2-1-3 for the medial surface setting protrusion for fixing section 2-1-1；It is sealing simultaneously
The flange 1-1 cooperated for same clamp 2-1-3 is arranged in the end of chamber 1.When in use, will be turned by clamp 2-1-3 and flange 1-1
Parallel operation 2 snaps fit onto the top of seal chamber 1.
