It sets, belongs to the technical field of medical instrument.
Background technology
Currently, the positioning for intrapulmonary lesser tubercle, majority is achieved using modes such as buckle wire or microcoils
Certain effect.But incisxal edge should be convenient for for the deep tubercle at (non-peripheral) in intrapulmonary position, positioning and label requirement
Measurement, can also meet long-time indwelling in the clinical demand of intrapulmonary.There is no at present for intrapulmonary it is deep position in tubercle it is special
Instrument.
Buckle wire is commonly used at present localization method, by Plunkett etc. 1992 according to metal hook to breast
The principle of gland small lesion location technology proceeds by the research positioned to lung's peripheral tubercle with metal hook at CT and reality
It tramples.Buckle wire is that an elongated front end bends to hook-shaped wire, and head end is fixed on intrapulmonary in hook-shaped, in CT
Scan orientation rear enclosure pin puncture enters, when operation after CT Guided Percutaneous is using near trocar puncturing to lesion or its, general
Wire discharges and recycles trocar, and front end is launched into hook-shaped, plays fixed function.It repeats CT scan and shows that hook expansion is opened
And (apart from lesion edge in lesion or neighbouring lung tissue<5mm).Cut metal wire, wire be located at patient in vitro
Part, and it is sent to operating room row wedge-shape excision of lung around wire under thoracoscope immediately.
In different research reports, buckle wire technique successful rate positions the main reason for failing between 58%-95%
It is wire dislocation, document report pilot pin displacement abjection incidence is 1.8%~6.4%, once displacement occur may cause
In turn on chest, in some instances it may even be possible to the serious consequence for causing lesion in art to be omitted.The common complication of buckle wire technology be pneumothorax,
Bleeding, pain and pleura reaction, the wherein incidence of pneumothorax are close to half.The complication of buckle wire technology most serious is gas
Body embolism.Although gas embolism is found in any Percutaneous lung puncture technology, it should be noted that there is document to summarize under CT guiding

Belong to and need to limit patient activity after silk positioning, preoperative transhipment, action is soft when putting position, and transfer to hand from CT Room as early as possible
It performs the operation art room, it is ensured that perform the operation immediately after positioning, the mode of this running also has certain difficulty in busy hospital.
But this method is also not suitable for the telltale mark of lung deep tubercle, and one of reason, which is strip wire, can not carry out palpation,
Tip is very sharp keen, and palpation most probably causes needle to stab wound surgeon by force；Reason second is that strip wire is pulled
Afterwards, it is easy to deviate from outside lung, anchor station changes, and causes the erroneous judgement of lesion depth.
Microcoils are the platinum microcoils for Endovascular Embolization.Microcoils have opacity, itself it is tortuous at
The characteristics of shape.1994, Asamura reported 4 patient CT guided Percutaneous by radiopaque metal microcoils for the first time
It is placed directly in Lung neoplasm, perspective is carried out in art and finds tubercle (microcoils), then clamps line cutting stitching instrument
Row perspective confirms that tubercle is clamped again after microcoils, can then cut off tubercle.Microcoils positioning success rate with
Buckle wire is close.Major complications type is identical as buckle wire technology, but incidence is very low.
For microcoils technology compared with buckle wire, advantage is to be not easy to dislocate after placing intrapulmonary, can be with the long period
Indwelling is in patient's body, and since spring ring is small, there is frictional force on surface, and short time indwelling, will not be because of breathing in lung tissue
It moves and changes position, still can be constant with holding position in the case of dual-lumen cannula mechanical ventilation, sick lung compression, also substantially
Not pulled moderately by surgical instrument is influenced.And compared with Metal wire material, it need not perform the operation immediately after positioning, in this embodiment it is not even necessary to
Patient activity is limited, pre-operative preparation is more calm.But microcoils are to be used for vascular suppository material, are positioned as lung super suitable
Use should be demonstrate,proved, so not mating lung puncture needle, clinically more interim collocation Chiba puncture needles carry out localised puncture at present,
Operating procedure is complicated, and lacks the anti-gas-leak measure punctured for lung tissue, increases the difficulty of operation, also increases complication
Risk.
