Abstract
The utility model discloses a disposable surgical high-frequency snare, which comprises a handle, a push-pull machine, a steel wire sleeve and two steel wires, wherein the two steel wires penetrate the steel wire sleeve; one end head of each steel wire extending out from the steel wire sleeve is connected to a dragging block arranged in a guide groove of the handle; the dragging block is connected with the push-pull machine; the other end of each steel wire extending from the steel wire sleeve is relatively bent and connected as a snare; the disposable surgical high-frequency snare is characterized in that: the part where the two steel wires form the snare is provided with a plurality of bumps. The bumps of the disposable surgical high-frequency snare in the technical scheme act as teeth; polyp can be excised quickly by engagement of the bumps on the two steel wires, so that the pain suffered by the patient in surgery is relieved.
Description
Technical field
This utility model relates to operating theater instruments, particularly disposable surgical high frequency snare.
Background technology
In some operations, for example in the operation of some excision polyp, need use a kind of high frequency snare, this high frequency snare comprises handle, load push-pull, steel wire cover and two steel wires, and two steel wires pass the steel wire cover side by side, the one end stretches out the back bending of steel wire cover and connects into a snare, the other end is fixed on the guiding piece in the handle guide channel, and load push-pull links to each other with guiding piece, can drive steel wire by guiding piece and carry out folding and unfolding.During operation, the snare that steel wire is formed is enclosed within on the polyp, tightens up steel wire by load push-pull, and polyp is cut under the effect of steel wire.
This high frequency snare is simple in structure, easy to operate, but its sharpness is not enough, often polyp can not be excised rapidly, all causes very big misery can for the sufferer body and mind.Therefore, said structure is improved to obtain a kind of high frequency snare that is more prone to excise.
The utility model content
Technical problem to be solved in the utility model is at the existing technical problem of existing high frequency snare, proposes a kind of sufferer misery that alleviates, and is easy to the disposable surgical of polypectomy high frequency snare.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
Disposable surgical high frequency snare, comprise handle, load push-pull, steel wire cover and two steel wires, described two steel wires pass in the described steel wire cover, the end termination that two steel wires stretch out described steel wire cover is connected on the guiding piece in the guide channel of described handle, and guiding piece is connected with described load push-pull; The other end that two steel wires stretch out described steel wire cover is relative bending and is connected to form a snare, it is characterized in that, the part that two steel wires form described snare is provided with several projections.
Described projection is the inside continuous serration of direction.
Continuous serration on two steel wires is symmetrically distributed.
The described projection every steel wire of serving as reasons bends to wavy formation.
Described projection is the sleeve pipe of spacer sleeve on every steel wire.
Sleeve position on described two steel wires is staggered.
After adopting technique scheme,, can cut off polyp more rapidly during operation, alleviate the misery that sufferer is born because disposable surgical of the present utility model is provided with projection with the snare of high frequency snare.
