- 6 are please referred to Fig.1, the present invention provides a kind of technical solution：
Bronchoscope housing sacculus, as shown in Figures 1 to 3, including bronchoscope 1, the sacculus for being socketed in 1 front end of bronchoscope
2 and the balloon tube 3 inside sacculus 2, the top of bronchoscope 1 be embedded with camera lens 11, the inside center position of balloon tube 3
It installing and is equipped with cleaning pipe 34, the side of cleaning pipe 34 is provided with sacculus water pipe 31, and the other side of cleaning pipe 34 is provided with seal wire 35,
The bottom end of sacculus water pipe 31 is provided with junction block 32, and sacculus 2 is socketed at one centimeter of 1 front end of bronchoscope, 31 He of sacculus water pipe
Angle is 90 degree between junction block 32, and sacculus water pipe 31 and junction block 32 are an integral molding structure, and cleaning pipe 34 is upper and lower
The hollow structure of perforation.
In the present embodiment, seal wire 35 is made of inside and outside two parts, and outer layer is rolled up using high-quality stainless steel wire on spring lathe
Around into, and steel wire requires bright and clean, tough and tensile, high resilience, winding must uniformly tight, marshalling, pine it is close consistent so that lead
35 tolerance of silk is bent repeatedly, will not be fractureed under the effect of certain strength.
Specifically, the inside of cavity, that is, seal wire 35 of above-mentioned stainless steel wire, equipped with a straight and hard steel in seal wire 35
Silk core, the front end of the wire-core attenuates gradually, and the tip of wire-core and stainless steel wire front end are welded and fixed, and by wire-core
Tail end is welded and fixed with stainless steel wire tail end, facilitates and balloon tube 3 is guided and supported using seal wire 35, helps balloon tube 3
Into in tracheae lacuna, and balloon tube 3 is guided smoothly to reach lesion.
Further, bronchoscope 1 is using the branchofiberoscope of Beijing safe six directions commerce and trade Co., Ltd production, visual field
Angle：>=85 °, bending angle：Upper 130 °, 90 ° lower, cephalic par diameter：φ 5.3mm are inserted into pipe diameter：φ 6mm observe depth：
3-50mm clamps bore dia：φ 2.0mm, active length：530mm, overall length：800mm, mating circuit, power supply and camera lens 11
Also it can be provided by this producer, in addition, it is the prior art, art technology to arrive bronchoscope 1 and camera lens 11 involved in the present invention
Personnel may be implemented completely, be not necessarily to superfluous words, and the content that the present invention protects is not related to the structure to bronchoscope 1 and camera lens 11 yet
It is improved with operation principle.
In specific implementation, in order to facilitate the installation of bronchoscope 1 and sacculus 2, and bronchoscope 1 and sacculus 2 are ensured
Whole air-tightness after installation, the present invention staff make improvements the structure of bronchoscope 1 and sacculus 2, as a kind of preferred
Embodiment, as shown in Figures 3 to 5, the outer sheath of junction block 32 are equipped with retainer ring 33, and sacculus 2 is internally provided with inside groove 21, inside groove
21 surfaces are provided with through-hole 22, and 22 outer wall of through-hole is equipped with sealing rubber ring 23, and bronchoscope 1 is provided with card close to 2 one end of sacculus
Slot 12, inside groove 21 and card slot 12 are engaged by clamping, and junction block 32 and through-hole 22 communicate.
In the present embodiment, sealing rubber ring 23 and retainer ring 33 are engaged by clamping, and retainer ring 33 is facilitated to snap onto inside sealing rubber ring 23
Junction block 32 is inserted into through-hole 22.
Specifically, retainer ring 33 is made of medical silica-gel material, material is environment-protecting and non-poisonous, can be used directly, and utilizes simultaneously
Improve the air-tightness that sealing rubber ring 23 and retainer ring 33 connect.
Further, card slot 12 is in the arc being recessed inwardly, and the size of card slot 12 and inside groove 21 are equal sized, in convenience
Slot 21 snaps onto inside card slot 12, and sacculus 2 is fixed.
The bronchoscope housing sacculus of the present embodiment snaps onto 1 surface of bronchoscope when in use, by the inside groove 21 of sacculus 2
Card slot 12 in, balloon tube 3 snaps onto to the junction of bronchoscope 1 and sacculus 2 at this time, and by the junction block of balloon tube 3 32
The through-hole 22 for being directed at 2 inside groove of sacculus, 21 surface is inserted into so that sealing rubber ring 23 is stuck on retainer ring 33, conveniently to sacculus 2 and branch
Airway wall 1 is installed, while ensureing sacculus 2 and the whole air-tightness of junction block 32；
Integrality under peacetime state is as shown in Figure 1, pushing bronchoscope 1 and being entered with air bag 2 and balloon tube 3
Tracheal strips are observed by camera lens 11 so that bronchoscope 1 reaches the diseased region of tracheae, passes through air bag water pipe 31 at this time
Into sacculus 2, water filling makes sacculus 2 expand (as shown in Figure 6) and blocks tracheae, while camera lens 11 is located at the front end of sacculus 2, no
It can be influenced by the expansion of sacculus 2, ensure bronchoscope to bronchus distal end still as it can be seen that and keeping the cleaning pipe 34 of balloon tube 3 right
Distal end carries out visual lower flushing and biopsy；
And for compared in bronchiole, bronchus classification is overstepping the bounds of propriety thinner, because big thick tracheae has cartilage support, breathe
Shi Buhui is flat, more toward in lung thin bronchus do not have cartilage support, only tracheal smooth muscle, tracheole is easy thickness when breathing
Variation needs expansion of fetching water when doing bronchoscope operation distal end bronchiole, and the expansion of sacculus 2 can block bronchus so that
Water is not easy to flow out, and greatly reduces the trouble of medical staff, and easy to operate, highly practical.
In above example, it is stuck on retainer ring 33 by sealing rubber ring 23, it is convenient that sacculus 2 and bronchoscope 1 are carried out
Installation, while ensureing sacculus 2 and the whole air-tightness of junction block 32；Camera lens 11 is located at the front end of sacculus 2, will not be swollen by sacculus 2
Swollen influence ensures bronchoscope to bronchus distal end still as it can be seen that and making the cleaning pipe 34 of balloon tube 3 under the progress visually of distal end
Flushing and biopsy；Bronchus can be blocked by the expansion of sacculus 2 so that water is not easy to flow out, and greatly reduces the fiber crops of medical staff
It is tired and easy to operate, it is highly practical.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only the present invention
