Abstract
The utility model discloses a turning extending catheter for a bronchoscope. The turning extending catheter comprises a catheter body, an adjusting device and a handle; the catheter body is composed of a spring catheter body and a protection catheter body; the handle is fixed at the tail end of the catheter body; the catheter body is sleeved with the adjusting device. The turning extending catheter is inserted by a doctor into an instrument channel of the bronchoscope in an operation, is threaded out of an outlet of the channel and extends to the focus, the length of the part, entering the instrument channel of the bronchoscope, of the catheter body is fixed through the adjusting device, then a biopsy instrument is placed into the catheter to reach the focus, and the turning extending catheter is convenient to use and practical. By means of the turning extending catheter, the biopsy success rate is improved, and an advanced method is provided for conducting diagnosis and mini-invasive surgical treatment on early lung cancers.
Description
Technical field
What this utility model related to that a kind of bronchoscopy uses turns to extension conduit.
Background technology
At present, whole world sickness rate, cancer that mortality rate is the highest are pulmonary carcinoma.When most of patient is diagnosed with pulmonary carcinoma, often reach an advanced stage.Receive treatment at this one-phase, only can live through 5 years less than 5% patient.The five year survival rate that can greatly improve patients with lung cancer is made a definite diagnosis in the early stage biopsy of pulmonary carcinoma.
Bronchoscopy is one of important means of the early stage diagnosis and treatment of pulmonary carcinoma, and it can, to trachea, the direct perusal of bronchus tube chamber, do biopsy simultaneously, correctly diagnoses the illness.Bronchoscope can be treated pulmonary disease, can also topical to reach better therapeutic effect.
Because most early stages of lung cancer are found in the inclined to one side outer regions of central authorities, conventional bronchoscope cannot arrive this region.Bronchoscope, with turning to extension conduit can extend bronchoscopic instrument channel, makes movable detecting apparatus arrive the small lesion of lung periphery, improves the success rate of biopsy, for diagnosis and the minimally-invasive treatment of the early stage of lung cancer provide advanced means.
Utility model content
The purpose of this utility model is to provide that a kind of bronchoscopy uses turns to extension conduit, to turn to extension conduit to stretch into bronchoscope instrument channel, and pass from channel outlet, extend to focus, enter the length of bronchoscope instrument channel by actuator A/C main body, again movable detecting apparatus is sent in conduit, arrived affected area, convenient and practical.
For reaching above object, the technical solution adopted in the utility model is: bronchoscope, with turning to extension conduit, comprises catheter main body, actuator and hands handle; Catheter main body is made up of bourdon tube and protecting tube; Handle is fixed on the tail end of catheter main body; Actuator is enclosed within on catheter main body.
Described bourdon tube is made up of rustless steel flat wire, in the shape of a spiral.
Described catheter main body head end has the fixing moulding angle of round and smooth bending.
Described protecting tube is made up of politef, and bourdon tube outer surface is fixed in protecting tube pyrocondensation.
Described actuator is made up of brick glue.
Described handle is made up of polypropylene, and handle internal channel is communicated with catheter main body.
The utlity model has following beneficial effect: (1) bourdon tube of the present utility model, there is very strong compliance, be difficult for bending, there is very high coaxial twisting property simultaneously.
(2) catheter main body head end of the present utility model has the fixing moulding angle of round and smooth bending, by reversing catheter main body, make to turn to extend conduit more easily pushed enter complicated bronchial tree.
Brief description of the drawings
For content of the present utility model is more easily understood, according to instantiation also by reference to the accompanying drawings, this utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of bourdon tube.
Fig. 3 is the schematic diagram that this utility model coordinates bronchoscope to use.
Attached number in the figure is:
Catheter main body 1, actuator 2, handle 3, bourdon tube 4, protecting tube 5, bronchoscope 6, bronchoscope extend conduit 7 with turning to.
Detailed description of the invention
Concrete manufacture method can be with reference to Fig. 1, and 2,3 make this utility model.Bourdon tube 4 is made up of rustless steel flat wire, in the shape of a spiral; Protecting tube 5 is made up of politef, and bourdon tube 4 outer surfaces are fixed in protecting tube 5 pyrocondensations, forms catheter main body 1; Handle 3 is made up of polypropylene, and handle 3 internal channels are communicated with catheter main body 1, and handle 3 is fixed on the tail end of catheter main body 1; Actuator 2 is made up of silica gel, is enclosed within on catheter main body 1; Catheter main body 1 head end has the fixing moulding angle of round and smooth bending, and this angle has shaping die to make.
Should be appreciated that specific embodiment described above is only for explaining this utility model, and be not used in restriction this utility model.The apparent variation of being amplified out by spirit of the present utility model or variation are still among protection domain of the present utility model.
