Specific embodiment
Technical solution of the present invention is described in detail with reference to the accompanying drawing.
Embodiment 1, the present invention provides a kind of elastic hoe scalers, and referring to fig. 2, including cutter hub 11, the cutter hub are elasticity
Guidewire material production generally can be used in cutter hub, and the top of the cutter hub is insulation, when in use for preventing top position
The normal tissue of contact is accidentally cut.When production, the cutter hub is preferably to insulate close to the top position, referring to Fig. 3,
Normal tissue is further prevented accidentally to be cut, existing mode can be used in insulation production, for example applies insulated paint, forms insulating layer
(position of hatching is beaten in such as Fig. 1 and Fig. 2), in itself in application, the shape of cutter hub can be sheet, filiform, rod-shaped, helical form
Or the shapes such as annular shape certainly can also be by above-mentioned shape cooperation, such as by knife to adapt to mucosa infection tissue of different shapes
The top setting of body is spiral, and slabbing or rod-shaped is arranged in bottom end, in this way, when in use, when encountering the obstacle for needing to bypass,
Spiral helicine cutter hub top is easier to deform, it is easier to which cut-through object, especially controllable handle are rotationally advancing it, effect
More preferably, the top shape of cutter hub can be the shapes such as inverted U-shaped, inverted V-shaped or half elliptic, and diameter is more preferably greater than the straight of cutter hub
Diameter, in this way cutter hub and conductor it is top between form the region of easy bending, be easy to change direction when meeting with obstruction, make point of a knife
It is top to have convenient for the function of guiding.
Elasticity hoe scaler provided by the invention, cutter hub bent can be bent, therefore can adjust cut direction, and the scope of application is wider.
Embodiment 2, in actual production existing mode can be used the devices such as handle is set, i.e., it is referring to fig. 4, described
Elastic hoe scaler further includes casing 12 and handle 13, and by turncap 16, tightly lock is set on the handle described sleeve pipe on handle
It is equipped with the sliding part 14 that can be slided along handle, seal wire is installed in described sleeve pipe, one end of the seal wire is connect with cutter hub, separately
One end is connect with the sliding part, and electrode 15 is also equipped on the sliding part, and the electrode is connect with seal wire.In the application,
Can also use following manner be arranged: on the basis of embodiment 1, referring to Fig. 5, it is described elasticity hoe scaler further include casing 12,
Handle 13, fixing piece 21, fixing piece generally use squeezing handle, and one end of the handle is connect with fixing piece, and the other end is provided with finger
Ring 22；The fixing piece is connect with the handle by limiting device；The limiting device is solid including the first fixed block 23, second
Determine block 24 and clamping block 25, first fixed block is fixed on the handle, and second fixed block is fixed on the fixation
On part, there is interval between first fixed block and second fixed block, the interval is generally higher than equal to the cutter hub
Entire cutter hub can be placed in casing by length when not used in this way, naturally it is also possible to expose the length of casing for adjusting cutter hub,
As the mode for adjusting cutter hub length, certainly, the length of the cutter hub also can be used existing structure and adjust, and does not do and has herein
Body limits；Be respectively set on first fixed block and the second fixed block it is fluted, be provided on the clamping block with it is described recessed
The protrusion 27 of slot cooperation, the protrusion card is in the groove；It is additionally provided with sliding block 28 on the handle, specific sliding block can be with
It is set on handle using existing mode, for example is installed on the handle by sliding slot, set is connected on the fixing piece
Pipe 12, seal wire 18 is equipped on the sliding block, and the seal wire is located in described sleeve pipe and passes through the handle and fixing piece；It is described
One end that seal wire is not connected with the slide block is connect with the cutter hub；Electrode 15 is also equipped on the sliding block or handle, it is described
Electrode is connect with the seal wire.This structure, when needing to release cutter hub, it is only necessary to by clamping block from the first fixed block and second
It is removed on fixed block, cutter hub can be released by pulling the second fixed block to be bonded it with the first fixed block, be covered when not needing to release
When circle, clamping block is stuck on the first fixed block and the second fixed block, is located at cutter hub in casing, by the first fixed block and institute
The interval between the second fixed block is stated, more than or equal to the length of the cutter hub, therefore even if pushes sliding block that can not push away lasso
Out.This structure can prevent in actual use, the case where sometimes will appear maloperation: accidentally in advance push away lasso
Out, in this way, lasso is easy to meet its hetero-organization when moving, there is the risk for damaging its hetero-organization inner wall.Clamping block, first are consolidated
Determining block and the second fixed block can be used plastic production and forms.In addition, seal wire is opposite when this structure can pass through rotating handle
Sleeve rotating, and then facilitate operation.
Above-described embodiment is the illustration invented, and it is special should not to describe limitation with the exemplary embodiments of specification and attached drawing
The protection scope of economic rights.
The preferred embodiments of the disclosure and embodiment are explained in detail above in conjunction with attached drawing, but it is of the invention
It is not limited to the above embodiment and embodiment can also not take off within the knowledge of those skilled in the art
Various changes can be made under the premise of from present inventive concept.In the claims, any reference between parentheses should not be accorded with
Number be used as limitations on claims.Word "comprising" does not exclude the presence of element or step not listed in the claims.Word
First, second and the use of third etc. do not indicate any sequence, these words can be construed to title.
