Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to a kind of endoscopic surgery puncture needle.
Background technology
It is a kind of minimally invasive Clinics completed by scope working clamp road through scope puncture technique, although in belonging to advanced
Mirror technology, but in the past 30 years, the development of maturation has been obtained in the whole world.The technology be by puncture realize obtain cell,
Tissue, the diagnosis sample of liquid, can also carry out tapping treatment, moreover it is possible to realize the purpose of injection treatment.It is presently used in wearing
The scope of thorn, the puncture of EUS and non-EUS (i.e. common scope) is generally included, wherein, according in Different Organs
Application and design difference, and in particular to transtracheal mirror is punctured, transtracheal EUS is punctured, punctures through digestive endoscopy, passed through
Alimentary canal EUS puncture etc..
Existing corresponding puncture instrument report in the prior art, such as Publication No. CN200963155Y Chinese patent are public
The tissue cutting puncture needle under a kind of guiding for EUS is opened, it is by pedestal (1), locating ring (2), handle (3), needle body
(4) formed with nook closing member (5).Pedestal divides shank (1.1) and stylophore (1.2) two parts, and handle (3) is placed on the outside of shank (1.1),
Needle body (4) is placed in the middle part of the inner chamber of pedestal (1), and tail end is the top that standard interface (4.1) is fixed on handle (3) inner chamber.Nook closing member
(5) it is placed in the inner chamber of needle body (4).For the product in cutting operation, infinite place of dropping back, needle point easily pulls out mucous membrane, and vacuum suction is lost
Effect, operative failure is caused, operation success rate is lower, and this strongly limits the application of puncture needle product.
Utility model content
The purpose of this utility model is to provide a kind of available for the diagnosis such as biopsy, biopsy cells, drawing liquid and treatment
Endoscopic surgery puncture needle.
Technical scheme：The utility model provides a kind of endoscopic surgery puncture needle, and described puncture needle is by puncture portion, connection
Portion, operating portion composition, described puncture portion include can bent plastic tube 3 and needle tubing 2, be installed with interior core filaments 1 in needle tubing 2；Described company
Socket part is female Luer or snap-fitting；Described snap-fitting includes pressure cylinder 4-1, its internal buckle and steady core pole 4-3, institute
The operating portion stated includes operation handle 9 and scale core bar 22, and operation handle 9 is provided with male limiting card 14 and corresponding mother
Limiting card 8, each component of operating portion is linked as entirety by scale core bar 22, and realizes each assembly function.
Described buckle is made up of upper buckle 4-2, lower buckle 4-4 and the spring 4-5 between upper and lower buckle.
Described operating portion also includes needle tubing lever 11 and control inner core of the control needle tubing in desirable plastics in-pipe
The interior core filaments lever 13 of silk.
It is described can the near-end of bent plastic tube 3 be connected with the operation handle 9 of connecting portion.It is described can bent plastic tube, its material
Expect for polyether-ether-ketone；Plastics length of tube can be processed different according to different need for bronchoscope, digestive endoscope etc.
Preferred length.Can bent plastic tube effect be to be formed needle tubing and its internal instrument in pincers road safety, smooth pass through.
It the needle tubing, can move freely in bent plastic tube, near-end connection needle tubing lever 11, distally pass and bent can mould
The distal end of expects pipe 3.Its diameter can be in the range of existing needle tubing, and specific such as 17g-25g, (g is that unit gauge writes a Chinese character in simplified form, in full
Together).Needle tubing is made up of the needle body section after the needle point section and apical segment of distal end, the processing of needle point back segment hair side, can be
The lower development of ultrasound is visible.Needle point can be sharp keen homogeneous inclined-plane, and needle point section plays piercing tissue and cuts the effect of tissue.Pin
The bending in Guan Keqian Dao Neisuiqian roads and bend, and can move forward and backward, its material is stainless steel material.
Described interior core filaments 1 penetrate needle tubing, and near-end is connected with interior core filaments lever 13, distally passes the needle point section
Distally.The interior core filaments cross section is toroidal, and the distal end of interior core filaments is a round end.Interior core filaments pass through needle tube body portion, and distal end surpasses
Go out outside distal tip, axial lacuna is left between interior core filaments and needle tubing.Interior core filaments near-end can connect the control of core filaments in control
Handle, facilitate the stretching needle tubing of core filaments in control or exit needle tubing.
Described interior core filaments control handle is connected with interior core filaments, and needle tubing is stretched out or exited to core filaments in control.Needle tubing controls hand
Handle is connected with needle tubing, controls out pin and narrowing, and is provided with narrowing stopping means, and when lifting puncture needle in control art, needle point is always
In focus.Can bent plastic tube handle with can bent plastic tube be connected, control can bent plastic tube penetrate and extract clamp road when positioning.
Interior core filaments joystick can use conventional design, such as, can be the screw cap that a body portion has anti-slip veins, or
Design of the other easy handheld operations of person etc..
Scale stopping means is mobile and fixed at the scale with scale core bar, limitation needle tubing joystick movement position
Put, reach the length that control pin stretches out.
Regulation handle moves on scale core bar, finely tunes outer length of tube, and is connected with endoscopic forceps channel interface, reaches
It is integrated with scope, person easy to operation is individually operated.
Further, the outside of described operation handle 9, interior core filaments lever 13 and snap-fitting is provided with antiskid groove
Or anti-skidding boss.
Beneficial effect：The utility model punctures effect ideal, is especially suitable for obtaining growth structure sample；The needle tubing of puncture needle
Other punctures of the hardness of body section compared to equivalent diameter are threaded a needle, and design is much smaller, and this causes needle tubing operation when with pincers road flexing to hinder
Power reduces；Meanwhile need not worry about needle point in operating process and skidded off from mucous membrane.In art, patient can be with unrestricted choice execution group
Knit biopsy or cell Needle aspiration.High degree of the present invention simplifies puncture procedure, improves processing safety, was both adapted to
Alimentary canal EUS, tracheae EUS also is adapted for, be also suitable for through the conventional non-super endoscopic puncture of sound.
Design of the present utility model can meet the needs of any EUS mediation of alimentary canal and tracheae, it may also be used for
Pincers road through non-EUS, realize that direct-view is lower and puncture deep biopsy, drawing liquid etc..
Of the present utility model design changes traditional maloperation, and in art, patient can freely lift puncture needle, execution group
The cutting knitted, need not worry about needle point in operating process and skidded off from mucous membrane.High degree of the present invention simplifies puncture procedure, carries
High processing safety.
In a word, design of the present utility model is more used through digestive endoscope and warp with prominent novelty
Airway wall puncture instrument has obvious superiority.High degree of the present invention simplifies the operation of biopsy, improve operation into
Power and security, the training to operator is more simple, is advantageous to widely available.
