Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being a kind of new cavum laryngis puncture-intracavitary suture guiding
Device.
Background technique
Recently as social development and the raising of living standards of the people, people's health demand and the phase to good life
Prestige also correspondinglys increase.The patient populations for receiving voice related surgical increase year by year, and secondary vocal cords adhesion patient also increase accordingly,
There is an urgent need to a kind of easy to operate devices to prevent and treat the complication such as vocal cords adhesion, larynx web.
It is the effective methods of surgical for treating vocal cords adhesion and larynx web that adhesive band, which cuts the merging of cavum laryngis pellosil,.Bilateral sound
The lesions such as band lesion (such as bilateral vocal cords appoint kirschner oedema, Rectal sessile polyps) and papilloma of larynx, larynx leukoplakia involve preceding joint,
It is postoperative to be easier that vocal cords adhesion and secondary larynx web occurs because preceding joint and bilateral vocal cords are there are the surface of a wound, cause hoarseness,
Dysphonia, or even cause unsmooth breath, expiratory dyspnea, What is more needs row tracheotomy, has seriously affected the life of patient
Bioplasm amount.There is scholar to prevent post-operation adhesion using the mitomycin soak surface of a wound, achieves certain curative effect, but still have 50%
The failure rate of left and right.The merging of cavum laryngis pellosil is the postoperative secondary vocal cords adhesion of prevention bilateral vocal cords and vocal cords adhesiotomy rear defence
Only effective ways of tacky company again.Currently in the world usually using in the fixed larynx of staplers in Lichtenberger laryngoscope
Pellosil.The instrument is a gun-type device, suture fixed pellosil from inside to outside from cavum laryngis, and needs are above and below glottis by arc when operation
Outside suture needle ejection larynx of the shape with line, then suture is knotted in neck and is fixed.Since equipment purchase is inconvenient, the factors limit such as expensive
System can not be promoted the use of at home.It is used at home without molding instrument.There is scholar to use on injection needle row thyroid cartilage
Lower edge, which is punctured, imports in larynx the fixed pellosil that knots for suture, needs in the inside and outside knotting of larynx, pellosil needs when taking out by suture
Knot is taken out together.
However, the following defects and deficiencies exist for stitching unstrument in Lichtenberger laryngoscope used in the prior art：
Certain blindness is located in stitching unstrument glottis above and below in Lichtenberger laryngoscope, and stapler head is arc knot
Structure there are certain requirements the size of laryngoscope, be unable to complete when difficult laryngoscope case is using small laryngoscope (mirror body diameter is less than 1.5cm)
Operation.Lower edge, which is punctured, on injection needle row thyroid cartilage imports the fixed pellosil that knots in larynx for suture, is both needed to there are larynx is inside and outside
Knotting and pellosil need the problems such as taking out suture knot together when taking out.
In conclusion needing one kind that there is puncture position accurate positioning, cavum laryngis lead can be made smoothly to export, effectively reduce
The linagogue of laryngeal tissue penetration damage, and yet there are no report about this linagogue.
Summary of the invention
The purpose of the present invention is aiming at the shortcomings in the prior art, provide a kind of to have puncture position accurate positioning, can make
Cavum laryngis lead smoothly exports, effectively reduces the linagogue of laryngeal tissue penetration damage.
To achieve the above object, the technical solution adopted by the present invention is that：
A kind of new cavum laryngis puncture-intracavitary linagogue, the linagogue includes outer tube, inner core；It is described

Shape structure.
As a kind of perferred technical scheme, the barb-like structure is made using laser cutting.
As a kind of perferred technical scheme, the depth of the barb-like structure is at least more than inner core radius.
As a kind of perferred technical scheme, the barb-like structure includes suture slide-in portion, suture incorporating section, suture
Card-tight part；The suture slide-in portion is inclined surface structure, and the head end in suture slide-in portion is arranged at core surface position, suture
The bottom end in slide-in portion is connected with the transition of suture incorporating section；The suture card-tight part is bent along the head end in suture slide-in portion.
As a kind of perferred technical scheme, the overhead structure is 3-4mm with respect to the length that outer tube stretches out.
As a kind of perferred technical scheme, the head end hand of the inner core has connector, and the connector is equipped with limit
Position item；The positive stop strip is with respect to connector radial distribution, and positive stop strip is protruding with respect to connector；The connector it is another
One end is equipped with control handle；The peripheral distribution of the control handle has rack structure.
As a kind of perferred technical scheme, the head end of the outer tube is equipped with connection handle；The connection handle
One end be equipped with connecting tube；The connecting tube is equipped with limit card slot；The limit card slot is matched with positive stop strip.
The invention has the advantages that：
1, the new cavum laryngis puncture-intracavitary linagogue of one kind of the invention, after puncture needle punctures into cavum laryngis, in extraction
The special inner core for having barb-like structure of core, insertion, barb-like structure is hooked and clamping cavum laryngis inner seam lines, and withdrawing trochar will stitch
Line exports to outside larynx (neck) from cavum laryngis, and compared with stitching unstrument in Lichtenberger laryngoscope, this new puncture needle can pass through
Site of puncture is accurately positioned in lower edge on the thyroid cartilage at neck middle line position, effectively reduces laryngeal tissue penetration damage, easy to operate,
The adhesion rate again for reducing postoperative vocal cords, improves the quality of life of patient.
2, in the assembled condition, the distal end of inner core is stretched out from the distal end in outer tube, so that suture is led for inner core and outer tube
In operation, not by the constraint of outer tube, activity space range is big for lead device.
3, barb-like structure is made using laser cutting so that the shape of barb-like structure formed it is more stable, no
It can deform, convenient for catching on simultaneously clamping suture.
4, barb-like structure includes suture slide-in portion, suture incorporating section, suture card-tight part；Wherein, suture slide-in portion is to incline
Tiltedly design, quick and convenient can introduce suture；Suture incorporating section is in U-shape shape, provides space, the suture for suture storage
