Description
Technical field
The present invention relates to therapeutic treatment fields more particularly to a kind of utilize to digitize Space Reconstruction and 3D printing technique preparation
The method of tracheal tube.
Background technology
In tumor colli resection operation, the excision of larynx can be involved.Common practice is at the end of remaining tracheae at present
Tracheal tube in termination, tracheal tube is communicated by neck trepanning with the external world, for maintaining patient's eupnea（Do not pass through nose
Portion）.Such as discloses a kind of children application No. is the patent of CN201120298040.0 and fix suit with disposable tracheal tube, it should
Fixed suit has the tracheal tube fixed rope continuously latched and two locking devices to constitute by solid, outboard tube cornice.It uses
The practical neck circumferences of Shi Xianyu compare, and wipe out the additional length at tracheal tube fixed rope both ends, and tracheal tube fixed rope both ends are successively worn
The more locking end of the locking end of locking device, tracheal tube mounting hole, other side locking device, and be blocked in the mounting hole of end
Latch unidirectionally blocks.The utility model not only reduces the tracheal tube surprisingly probability of de- pipe and patient's skin of neck or surface of a wound damage
And infection risk, also mitigate patient suffering and medical staff's workload.
Tracheal tube obtained by patient of institute's some need using tracheal tube is finished product at present, is had different straight
However the tracheal tube specification of diameter, length and camber is still difficult to reach personalized requirement.Normalized finished product gas
Pipe-in-pipe has the drawback that：Since the diameter of patient airway, length and curvature differ greatly, normalized tracheal tube is used
It can not be adapted to patient airway's shape height, easily cause the air flue stimulation even Airway damage of some patientss.And for above-mentioned
Technical problem does not cause enough attention in state of the art, therefore there is no ideal solution at present yet.
Invention content
Digitlization Space Reconstruction and 3D printing technique system are utilized in order to solve the above technical problem, the present invention provides a kind of
The method of standby tracheal tube, the present invention have been put forward for the first time in this field and have been prepared using digitlization Space Reconstruction and 3D printing technique
The thinking of tracheal tube can make patient obtain personalized tracheal tube, according to patient itself air flue using the technology of the present invention
The tracheal tube that structure design optimizes makes the air flue of patient stimulate and damage and is preferably minimized.
The specific technical solution of the present invention is：It is a kind of to prepare tracheal tube using digitlization Space Reconstruction and 3D printing technique
Method, include the following steps：
1）By CT scan, patient's thin-layer CT data are obtained, reconstruction patients skin lower section tracheae anatomic form obtains editable
Three-dimensional modeling data.
2）To threedimensional model into edlin, planning and design scheme extracts the three-dimensional modeling data of tracheae under patient skin；
3）Into edlin based on the three-dimensional modeling data of patient airway, tracheal tube threedimensional model is designed.
4）After importing data to, using 3D printing technique, tracheal tube is made.
The present invention has creatively been put forward for the first time prepares tracheal tube using digitlization Space Reconstruction and 3D printing technique
Thinking, using the technology of the present invention can according to the personalized curvature of patient airway, diameter and other special medicines require come
The tracheal tube for designing and preparing optimization makes the air flue of patient stimulate and damage and is preferably minimized.
Preferably, step 1）In, the thickness of CT scan is less than or equal to 2mm.
Preferably, step 1）In, import sextuple tooth kind after the thin-layer CT data of acquisition are converted to DICOM data formats
Plant design software（6D-DENTAL Tech Co, Ltd, China）Tracheae anatomic form below reconstruction patients skin, acquisition can compile
The .stl format model datas collected.
Preferably, step 2）In, in conjunction with magics design softwares and Geomagice Studio design softwares to three-dimensional
Model extracts the three-dimensional modeling data of patient airway into edlin, planning and design scheme.
Preferably, the tracheal tube includes personalized casing and fixed seat；The fixed seat is equipped with through-hole, described
The upper end of personalized casing is detachably connected with the through-hole；Step 3）In, the only threedimensional model of design personalized casing is fixed
Seat is general finished product.
3D printing cost is higher, for control cost, tracheal tube is designed as split type, 3D printing is the most key
Personalized sleeve portion, and fixed seat is previously prepared general finished product.Personalized casing and fixed seat can by being spirally connected or
The realizations such as clamping connection.
Preferably, the personalization casing is metal material.
Although theoretically, the tracheal tube of the flexible materials such as plastics, silica gel is due to having flexibility, after insertion with tracheae
Damage can smaller.But team of the present invention is after studying for a long period of time by finding, the tracheal tube surface light of the flexible materials such as plastics
Slippery is insufficient, be easy to cause the formation of sleeve surface phlegm scab and causes cannula occlusion, is easy to cause discomfort to patient instead, can increase trouble
The pain of person and psychological burden.And the characteristic for using metal material its surface can be utilized smooth prevents phlegm scab from forming blocking air flue.
One of optionally, tracheal tube further includes waterproof and breathable cover；The waterproof and breathable enclosure is set to fixed seat
The outside of upper through-hole.
Patient is breathed after installing tracheal tube by the through-hole in fixed seat, since through-hole is opening, special
Under environment（Such as bathing, serious haze sky, dust environment）, steam, particulate matter in air etc. easily enter tracheae, cause to suffer from
Person's cough etc..For this purpose, the present invention is arranged with waterproof and breathable cover in the through hole of fixed seat, can not only effectively prevent steam,
Particulate matter etc. enters tracheae, and its good permeability, can not influence eupnea farthest.And make being not required to
Used time can be dismantled.In contrast, common strainer can not stop steam, and can stop steam filter layer it is ventilative
Property again it is not good enough.
Further, the part that the waterproof and breathable cover is located at through-hole surfaces is polytetrafluoroethylene (PTFE) waterproof ventilated membrane.
The waterproof ventilated membrane of polytetrafluoroethylene (PTFE) material is the best waterproof ventilated membrane of current water-proof breathable properties.Its extensive use
In construction material, communication equipment and chemical field, the present invention is dexterously applied on tracheal tube.
It is compared with the prior art, the beneficial effects of the invention are as follows：
1. the present invention has been put forward for the first time in this field and has prepared tracheal tube using digitlization Space Reconstruction and 3D printing technique
Thinking can make patient obtain personalized tracheal tube using the technology of the present invention, most according to the design of patient itself air passage structure
The tracheal tube of optimization makes the air flue of patient stimulate and damage and is preferably minimized.
2. the tracheal tube of the present invention is equipped with waterproof and breathable cover, can stop in the case where not influencing eupnea
Steam, particulate matter enter tracheal strips.
