Description
Technical field
The utility model relates to the field of medical instrument technology, specifically a kind of for the pipe through bronchoscopic biopsies needle
Sheath structure.
Background technique
It is to pass through tracheae using a kind of special puncture needle with flexible conduit through bronchoscope needle suction biopsy art
The biopsy channel of mirror enters in air flue, then penetrates tracheal wall and draws to lesion progress needle piercing and sucking outside trachea-bronchial epithelial cell chamber, obtains thin
Born of the same parents or tissue specimen carry out a kind of new technology of cytology or pathological examination.
Surgical procedure is as follows:
1. carrying out inspection puncture needle before entering bronchoscope biopsy mouth, look at whether internal and external pin disengaging is smooth.Then interior needle
It is lockked with outer needle, then the outer needle of needle in lockking is moved back in stylophore.
2. puncture needle inputs biopsy channel, until going out biopsy opening distal end, stop conveying after exposing becket.Alignment punctures
After point, the outer needle of needle in lockking is released.
3. the position set in advance with interior pin puncture passes through airway walls and reaches the tumour or lymph node for needing biopsy, then
Interior needle is retracted into outer needle, takes tissue using the cutting of outer needle and the swabbing action of syringe.End of operation, then outer needle is also moved back
Enter intrathecal.
4. outer needle is released and locked again, air is injected toward pump orifice, the content of acquirement is pushed away and is fixed in load slope on piece
Inspection.
One success or failure performed the operation and step 2 are closely related, if the bending angulation of biopsy needle is insufficient, will lead to two kinds
As a result: 1. point of puncture misalignments deviate lesion；2. biopsy needle is unable to complete penetration bronchial wall, tissue extraction cannot achieve.With
Upper two kinds of results will lead to operative failure, be even more important so the bending angulation of biopsy needle seems.
Therefore, no matter from the angle of product clinical use, or from the angle of patient, biopsy needle can sufficiently be bent angulation,
The key factor of device design consideration will all be become.
Summary of the invention

The diameter of the inner core is 0.2-0.3mm.
The middle pipe is made of high molecular material, and the outer tube is made of high molecular material, the high score
Sub- material is PTFE.
The utility model compared with the existing technology, the advantage is that: by structure to inner core, middle pipe structure and outer tube and
The design of its connection type realizes the abundant bending angulation of biopsy needle, in preferred technical solution, outer tube and middle Guan Caiyong
High molecular material is made, and can realize 180 ° of bendings of outer tube and middle pipe respectively, by the size design to inner core, guarantees to use
Inner core made of metal material is able to achieve 180 ° of bending, by the Design of length of middle pipe, realizes that biopsy needle can be sufficiently freely curved
Bent angulation, and it is directed at point of puncture, penetrate the effect of bronchial wall.
