Description
Technical field
The utility model relates to technical field of medical instrument, in particular to a kind of hepatology device for removing calculus of intrahepatic duct.
Background technique
Effect of lithotomy net during choledochoscope takes stone is very important, and suitable stone taking device can easier take out
Calculus greatlys save the operating time.But in actual operation, " taking property of difficulty " calculus can be encountered frequently, needed using not
With the stone taking device of feature, existing stone taking device generallys use lithotomy net and carries out taking stone, and such stone taking device is difficult to effectively fixed
Position, and embedding calculus within the organization is difficult to take out.
Utility model content
In view of the above drawbacks of the prior art, the technical problem to be solved by the utility model is to provide a kind of hepatologies
Device for removing calculus of intrahepatic duct.
To achieve the above object, including casing, restraining position ring block is connected in described sleeve pipe, the stop collar upper end passes through spring
It is connected with sliding block, the slider bottom is connected with above sliding block described in the bracing wire extended to outside pipe from sleeve bottom the material that is hingedly magnetic
The claw of matter, the claw include the interconnecting piece being hinged on sliding block and the card being connected on interconnecting piece and portion, the connection
Portion, which is directed away from cannula center inclination and extends obliquely upward to be bonded on the inside of sleeve upper end mouth, to be extended to outside casing, and the card and portion to
It is bent at cannula center, described sleeve pipe upper end and claw opposite side are connected with positioning plate, and the positioning plate has towards claw side
The fixing groove of indent is embedded with the magnetic for being adsorbed on claw back on the side wall of described sleeve pipe end.
The above structure extends to positioning plate below calculus, pulls out bracing wire, and claw is closed towards positioning plate side, will
Calculus is clamped, and the fixed of calculus is facilitated to take out, and particularly with the calculus of insertion within the organization, positioning plate is between tissue and calculus
Gap be inserted into below calculus, facilitate positioning；Calculus is trapped in fixing groove, so that calculus is fixed, is effectively prevent
Gallstone slide comes out in drawing process, and during claw slides up and down, claw back is adsorbed by magnetic always, works as claw
When running up, claw is opened, when claw is run down, claw closure.
Preferably, the positioning plate and casing are integrally formed.
Preferably, the bracing wire bottom is connected with pull ring.
Preferably, the claw is provided with bur towards positioning plate side.
Preferably, the positioning plate has anti-skid chequer towards claw side.
The beneficial effects of the utility model are: the utility model structure is simple, it can be achieved that the effective of the calculus of difficult taking property
It takes out, and facilitates positioning during taking calculus, enormously simplify operation, it is easy to use.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, to achieve the above object, this programme includes casing 1, connects restraining position ring block 2 in casing, on stop collar
End is connected with sliding block 4 by spring 3, and slider bottom is connected with the bracing wire 9 extended to outside pipe from sleeve bottom, and bracing wire bottom is connected with
Pull ring 10.
The claw 5 of magnetic material is hinged with above sliding block 4, claw uses iron material in the present embodiment, and claw 5 includes
The interconnecting piece 5a being hinged on sliding block and the card and portion 5b that are connected on interconnecting piece 5a, the interconnecting piece 5a are directed away from casing
Central side, which tilts upward extension and is bonded on the inside of casing 1 upper port, to be extended to outside casing, and the card and portion 5b are to curved at cannula center
Folding, 1 upper end of described sleeve pipe and 5 opposite side of claw are connected with positioning plate 6, and the positioning plate 6 has consolidating for indent towards 5 side of claw
Determine slot 7, the magnetic 8 for being adsorbed on 5 back of claw is embedded on the side wall of 1 end of described sleeve pipe.
In the present embodiment, positioning plate 6 and casing 1 are integrally formed.
In the present embodiment, the claw 5 is provided with bur 11 towards 6 side of positioning plate, and the positioning plate 6 is towards claw 5
There is anti-skid chequer in side.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
