Abstract
The utility model discloses a choledochoscope inserting tube which comprises a sleeve tube, a first stainless steel knitmesh tube and a spring tube. The spring tube is sleeved with the first stainless steel knitmesh tube, the first stainless steel knitmesh tube is sleeved with the sleeve tube, the sleeve tube is of a step-shaped structure which is divided into a front section, a middle section and a tail section, a second stainless steel knitmesh tube is added to the inner side of the middle section and the inner side of the tail section, the front section is connected to a connecting ring, and the tail section is connected to an equipment connector. The choledochoscope inserting tube is large in tortuosity, flexible in operation and convenient to mount, through the application of the choledochoscope inserting tube, omission of lesions can be avoided, operation duration can be shortened, and diagnostic capability and diagnostic efficiency can be improved.
Description
Technical field
This utility model relates to medical appurtenance field, especially a kind of choledochoscope insertion tube.
Background technology
Check the methods that adopt naked eyes or rigid choledochoscope more in existing gallbladder, easily omit and cause recurrence, and gallbladder otch is large, wound is large.The hardness of choledochoscope insertion tube is large, movable insensitive, checks not comprehensively, easily omits pathological changes.
Utility model content
The purpose of this utility model is to provide a kind of choledochoscope insertion tube, and flexibility is large and check that wound is little comprehensively, recovers fast.
To be solved in the utility model is that the hardness of existing choledochoscope insertion tube is large, movable insensitive, checks not comprehensively, easily omits the problem of pathological changes.
The technical scheme that this utility model solves its technical problem employing is: this utility model comprises sleeve pipe, the first rustless steel knitmesh pipe, bourdon tube adapter ring and equipment connection head; The first described rustless steel knitmesh pipe box is on bourdon tube, described sleeve pipe is placed on the first rustless steel knitmesh pipe, it is characterized in that the described stepped structure of sleeve pipe, be divided into leading portion, stage casing and latter end, stage casing and end section are provided with the second rustless steel knitmesh pipe, the second rustless steel knitmesh pipe box is on the first rustless steel knitmesh pipe, and the leading portion of insertion tube connects adapter ring, end connection device union joint.
The beneficial effects of the utility model are: bourdon tube adopts rustless steel steel disc to make the internal diameter size that helical structure can be controlled sleeve pipe.Rustless steel knitmesh inside pipe wall two ends are welded with stannum, and because rustless steel knitmesh pipe is apertured, stannum can be penetrated on bourdon tube, is then fixed together with bourdon tube.Sleeve pipe adopts polyurethane tube, and tensile strength, tearing toughness are good, long service life.Sleeve pipe adopts the design of syllogic, for the sleeve pipe of the different phase design different-diameter inserting and different hardness, effectively reaches the object of inspection.Rustless steel knitmesh pipe can be controlled the level of stretch of sleeve pipe, prevents that sleeve pipe from excessively being elongated.The white bed of material is transparent, can increase the smoothness of cover epidermis face.The adapter ring at insertion tube two ends and equipment connection head can be assembled other assemblies of choledochoscope easily.
This utility model flexibility is large, and flexible operation, easy for installation is used this insertion tube, can avoid omitting pathological changes and shortening operating time, is conducive to improve diagnosis capability and diagnosis efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, this utility model comprises sleeve pipe 10, the first rustless steel knitmesh pipe 7 and bourdon tube 8.The first rustless steel knitmesh pipe 7 is placed on bourdon tube 8, and sleeve pipe 10 is placed on the first rustless steel knitmesh pipe 7.
The stepped structure of sleeve pipe 10, is respectively leading portion 2, stage casing 3 and latter end 4, and the outside dimension in sleeve pipe stage casing 3 is greater than the outside dimension of sleeve pipe leading portion 2, and the outside dimension of sleeve pipe latter end 4 is greater than the outside dimension in sleeve pipe stage casing 3.
Stage casing 2 and latter end 4 places are provided with the second rustless steel knitmesh pipe 9, the second rustless steel knitmesh pipes 9 and are placed on the first rustless steel knitmesh pipe 7, and the leading portion of insertion tube connects adapter ring 1, end connection device union joint 5.Adapter ring 1 and equipment connection head 5 are welded on respectively the two ends of the first rustless steel knitmesh pipe 9.
The two ends 6 of the first rustless steel knitmesh pipe 7 inwalls and 11 are fixed together by scolding tin and bourdon tube 8.
On sleeve pipe 10 external diameters, be stained with cover skin, cover epidermis face repastes the white material that last layer is transparent.
Insertion tube total length scope is 636mm-638mm.
The helical structure that bourdon tube 8 processes for rustless steel steel disc, sleeve pipe 10 adopts polyurethane tube.
