Description
Technical field
This utility model relates to a kind of medical snare.
Background technology
Medical snare coordinates high-frequency electrical to the excision of various polyp and excess tissue under being mainly used in scope.The basic structure of existing snare is: pipe handle is set with moveable finger ring circle, and the front end of pipe handle is fixedly connected with the tail end of sheath pipe, and finger ring circle is connected with tinsel two ends; Tinsel one end forms ring, extends to the front end of sleeve pipe from pipe handle.During excision polyp, sleeve pipe is input to the affected site in human body through endoscopic forceps channel.When finger ring circle opposite handle moves forward, the front end from sleeve pipe is stretched out by ring wiry, and automatically forms snare under the elastic dilatation of metal self.By endoscopic views, be enclosed within polyp by snare, then moved backward by finger ring circle opposite handle gradually, snare diminishes thereupon gradually, until the polyp that is locked, then by tinsel electrified regulation, makes polyp be solidified excision from normal structure.The stroke of this snare is general longer, the doctor less for palm or nurse, and bimanualness must could realize the flexible of tinsel ring, it is very inconvenient therefore to operate.
Utility model content
The technical problems to be solved in the utility model is: cause unhandy problem in order to overcome existing snare because stroke is long, this utility model provides a kind of medical snare.
This utility model solves the technical scheme that its technical problem adopts: a kind of medical snare, comprise handle and sheath pipe, the tinsel extending to sleeve pipe front end from handle is equipped with in described sheath pipe, tinsel forms ring in the one end away from handle, described handle is provided with driving mechanism, described drive rod drives tinsel to move near one end of handle, described driving mechanism comprises the shifting part be located in handle, the first gear is also comprised in described driving mechanism, second gear and drive rod, described first gear is connected by through-drive with the second gear, the diameter of described first gear is less than the diameter of the second gear, described shifting part and drive rod are rack structure, first gear and shifting part are in transmission connection, second gear and drive rod are in transmission connection, described shifting part leads with handle and is connected.
Described tinsel is fixedly connected with drive rod near one end of handle.
Described handle is provided with high-frequency electrical plug, one end tinsel electrical connection of described high-frequency electrical plug.
One end and the drive rod of described high-frequency electrical plug are slidably connected, and described drive rod is that conducting metal material or drive rod surface are provided with conductive layer, and tinsel contacts with drive rod and fixes.
The tooth of described shifting part and the tooth of drive rod are oppositely arranged and shifting part and drive rod are all slidably connected with handle.
Conveniently operate, one end of described shifting part is with the first finger ring circle, and described handle is provided with at least one second finger ring circle, and described first finger ring circle is all coplanar or parallel with the plane of movement of shifting part with the second finger ring circle.
In order to adapt to the operating habit of doctor, described shifting part is contrary with the direction of motion of drive rod.
The beneficial effects of the utility model are, medical snare of the present utility model, can realize one-handed performance, and operate steadily reliable, structure is simple, easy to operate.

Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As Figure 1-4, the medical snare of one of the present utility model, comprise handle 1 and sheath pipe 2, the tinsel 3 extending to sleeve pipe front end from handle 1 is equipped with in described sheath pipe 2, tinsel 3 forms ring 3-1 in the one end away from handle 1, described handle 1 is provided with driving mechanism, described drive rod 7 drives tinsel 3 to move near one end of handle 1, described driving mechanism comprises the shifting part 4 be located in handle 1, the first gear 5 is also comprised in described driving mechanism, second gear 6 and drive rod 7, described first gear 5 and the second gear 6 are in transmission connection by axle 11, described shifting part 4 and drive rod 7 are rack structure, first gear 5 is in transmission connection with shifting part 4, second gear 6 is in transmission connection with drive rod 7, described shifting part 4 leads with handle 1 and is connected.The diameter of the first gear 5 is less than the diameter of the second gear 6, thus amplifies the stroke of drive rod 7.Described tinsel 3 is fixedly connected with drive rod 7 near one end of handle 1.In order to adapt to the operating habit of doctor, shifting part 4 is contrary with the direction of motion of drive rod 7; Shifting part 4 is relevant with the mode that is crisscross arranged of gear and tooth bar with the direction of motion of drive rod 7; change this to arrange; the direction of motion can be changed; the direction of motion setting that the present embodiment adopts is the operating habit in order to adapt to doctor, but being arranged to reverse motions direction still belongs to this patent protection domain.
