Abstract
A kind of ensure that flexible puncture needle prevents from not thrusting the Multi-section retractable flexible puncture needle inner support device that in-house flexible puncture needle part bends in piercing process, devise and there is the Multi-section retractable tube-in-tube structure supporting small structure, when flexible puncture needle meets obstructions in puncture owing to the supporting role of centre bore of sleeve is without bending, thus ensure puncture needle thrusting smoothly and being accurately positioned in piercing process.Its critical component is end to end multiple telescopic sleeve pipe with centre bore supporting construction, and multi-joint telescoping sleeve pipe centre bore of inside in telescopic process provides effective straight support to flexible puncture needle all the time thus avoids flexible puncture needle to bend.
Description
Technical field
The present invention relates to a kind of Multi-section retractable flexible puncture needle inner support device, belong to flexible puncture needle thorn in aspiration biopsy
Fashionable feed motion supporting construction, relates to the technical field such as Machine Design, medical science.
Background technology
Telescopic flexible puncture needle inner support device is multiple for flexibility for being designed with in multiple-segment telescopic tube on technology type
Puncture needle provides the coaxial aperture of rigid support.
In the technical fields such as clinical medical aspiration biopsy, accurate feeding and the location of flexible puncture needle is to ensure that puncture
The key technology at position.Generally when flexible puncture needle head is when running into bigger penetration Resistance, it is introduced into organization internal
Flexible puncture needle unstability buckling phenomenon can occur, thus cause flexible puncture needle can not be accurately positioned at organization internal, even
Owing to occurring excessive bending to cause cannot continuing to thrust.
There is presently no and ensure that flexible puncture needle is not thrust in-house flexible puncture needle part in piercing process and do not sent out
The efficient apparatus of raw bending.
In this context, the present invention provides a kind of provides rigidity to prop up it flexible puncture needle during lancing motion
Support, prevent flexible puncture needle diastrophic Multi-section retractable flexible puncture needle inner support device, wearing solving flexible puncture needle
What during thorn, the bending of generation unstability brought positions inaccurate problem to site of puncture.
Summary of the invention
The present invention solves its technical problem and adopts the following technical scheme that.
For solving the problem that occurs bending and deformation in lancing motion of flexible puncture needle, devise inside have multiple coaxially
The Multi-section retractable sleeved tubular structure of small structure, it is mainly saved sleeve (1), first joint housing supports end (2), second section by head
Sleeve (3), second section housing supports end (4), Section of three sleeve (5), Section of three housing supports end (6), Section of four sleeve (7),
Section four, housing supports end (8), Section of five sleeve (9), Section of five housing supports end (10), minor details sleeve (11), minor details sleeve
Support end (12), end connectors (13) form, and the length of telescopic joint, quantity can be carried out according to the length of flexible needle accordingly
Adjust；It is characterized in that: this flexible puncture needle inner support device by more piece from big to small, end to end telescopic sleeve form,
Each joint sleeve is all and housing supports end corresponding with its diameter is by thread connection, has female thread structure, respectively in each joint sleeve
Joint housing supports end has external thread structure；Each joint housing supports end circle centre position has the aperture supporting flexible puncture needle, respectively saves sleeve
A telescopic tubular sleeve structure is formed by thread connection with each joint housing supports end；Internal several apertures have coaxially
Characteristic also plays the effect supporting flexible puncture needle；First joint sleeve is provided with mounting flange seat；End connectors is provided with mounting flange
Seat, can be fixed on whole puncture needle inner support device by the two flange seat on the dynamic slide unit handling puncture needle, and ensure whole
Set flexible puncture needle is in linear state all the time, and the joint number of sleeve can increase according to the length of flexible puncture needle or reduce.
Accompanying drawing explanation
The present invention provides Figure of description as follows.
Fig. 1 is Multi-section retractable flexible puncture needle inner support device appearance schematic diagram.
Fig. 2 is Multi-section retractable flexible puncture needle inner support device vertical section structural map.
Detailed description of the invention
Present invention structure as shown in accompanying drawing 1 and accompanying drawing 2 is implemented, and it is mainly saved sleeve (1), first joint housing supports end by head
(2), second section sleeve (3), second section housing supports end (4), Section of three sleeve (5), Section of three housing supports end (6), the 4th
Joint sleeve (7), Section of four housing supports end (8), Section of five sleeve (9), Section of five housing supports end (10), minor details sleeve
(11), minor details housing supports end (12), end connectors (13) composition.
When using this Multi-section retractable flexible puncture needle inner support device to carry out puncture working, first by this flexible puncture needle
Support device is fixed on sliding platform by the flange seat of first joint sleeve, and this sliding platform can together do puncture fortune with flexible puncture needle
Dynamic, the flange seat of end connectors is fixed near being pierced on the fixed mount at place, then flexible puncture needle penetrates this eyelid retractor
Each internal coaxial support aperture, allows lid flexible needle inner support device be maintained at the shape of elongation before flexible puncture needle thrusts tissue
State, when flexible puncture needle carries out lancing motion with sliding platform, the telescoping tube of this eyelid retractor can occur compression with motion and begin
Keep linear state eventually, thus prevent flexible puncture needle from bending, even if when puncture needle runs into penetration Resistance, coaxial support
Small structure is prevented also from flexible puncture needle generation unstability buckling phenomenon, it is ensured that being smoothed out and being accurately positioned of puncture.
