Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
The multidirectional adjustable electric knife of one kind as shown in Figures 1 to 5, including handle portion 1, the hose sections being connect with handle portion 1
2, it is connected to the cutter head portion 3 of 2 end of hose sections, cutter head portion 3 connects power supply, wherein hose sections 2 is solid hose or hollow soft
It manages, in the present invention preferably solid hose.
It is installed with two pairs of guide lines 4 in hose sections 2, is parallel to each other between guide line 4, has in hose sections 1 and is guided for each item
The hole that line 4 passes through.Hose sections end is fixed in each 4 one end of guide line, and contacts or connect cutter head portion 3 respectively；In handle portion 1
Being provided with coaxial two can connect respectively after being pierced by hose sections 2 along the control button 5 that handle portion moves back and forth, each pair of guide line 4
Connect a control button 5, two pairs of guide lines 4 in hose sections 2 respectively where plane intersect at 2 central axis of hose sections and
It is mutually perpendicular to, when each control button 5 is mobile to different directions respectively, each guide line 4 can be drawn respectively, drive hose sections 2
Bending with dynamic cutter head portion 3 to turn to.Varying pitch spring 8 is arranged with outside hose sections 2, wherein varying pitch spring 8 includes close
The high density spring section 802 of the low-density spring section 801 of hose sections end and separate hose sections end, low-density spring section 801
Length be greater than 0, less than the 1/2 of 8 entire length of varying pitch spring；Wherein varying pitch spring 8 is coated with covered plastics layer 10.Become spiral shell
The distortion and its deformation of hose sections can be effectively prevented away from spring, it being capable of the significantly more efficient deformation for guaranteeing its head end.
Eyelet strip 6 is also equipped in handle portion 1, eyelet strip 6 is arranged perpendicular to the central axis of handle portion 1, in eyelet strip 6
On be provided with two pairs of threading holes 61, two pairs of threading holes 61 in hose sections 2 perpendicular to a pair of two 5 central axis of control button
4 place plane of guide line is symmetrical arranged for the plane of symmetry, and two pairs of guide lines 4 are each passed through these two pair threading hole 61, and are connected to most
On close control button 5.The distributor plate 7 parallel with eyelet strip 6 is also set up in handle portion 1, opens two pairs points on distributor plate 7
Line pearl 701, respectively with each pair of 4 place co-planar of guide line, each guide line 4 is each passed through coplanar two pairs of separated time pearls 701
Separated time pearl 701.In hose sections 24 place plane of one pair of them guide line perpendicular to two control buttons 5 central axis, separately
A pair of of 4 place plane of guide line is parallel to the central axis of control button 5.The rear and front end of control button 5 passes through spring 9 respectively
It is connected with handle portion inner wall.
In order to power to cutter head portion 3, each 4 material of guide line is selected as conductor, cutter head portion 3 connects electricity by guide line 4
Source, also, at least one in distributor plate 7 and eyelet strip 6 is conductor, also installation connects to power supply on the tail portion of handle portion 1
Electrode 11, electrode 11 are connect with the distributor plate 7 of conductive material or eyelet strip 6, and are powered by guide line 4 to cutter head portion 3.
As shown in Figure 1, Figure 2 and Fig. 5 shown in, be between the guide line 4 in hose sections 2 it is arranged in parallel, guide line 4 is worn
After hose sections 2 enters in handle portion 1 out, can not continue to keep relatively parallel state, and due to rotating disc 5 and guide line 4,
That there are relative positions is poor for hose sections 2, so guide line 4 can not precisely effectively in the case where no eyelet strip 6 is with distributor plate 7
The curved direction of hose sections 2 and amplitude are controlled, and is provided with after distributor plate 7 and eyelet strip 6, four are respectively provided on two plates
The absolutely fixed threading hole 61 in position thus passes through the guidance and fixation of threading hole 61, limits the displacement of guide line 4, energy
So that guide line 4 is driven hose sections 2, precisely turns to.The torsion of hose sections can be effectively prevented with the setting of time-varying pitch spring
Bent and its deformation, being capable of the significantly more efficient deformation for guaranteeing its head end.
In conjunction with attached drawing 6, application method of the invention is described further.
Cutter head portion 3 and hose sections 2 are transported to operative site by endoscope channel or other accessory channels to perform the operation,
Hand-held handle portion 1 is operated, and by moving forward one of control button, is pulled and is connected or contact at the A in cutter head portion 3
Guide line 4, be bent hose sections 2 to the direction X+ with dynamic cutter head portion 3, be bent and restore after reset, similarly by moving backward this
Control button pulls curved to the direction X- with dynamic cutter head portion 3 with connection at the B in cutter head portion 3 or the guide line 4 contacted, hose sections 2
Song is bent after reset and restores, this description is suitable for the bending in two direction X-direction axis X+, X- in the case of the control of single control button,
Similarly increase a control button, by the guide line 4 for pulling respectively with connecting or contact at C, the D in cutter head portion 3, can control
The bending in two direction Y direction axis Y+, Y- can be combined into X, in Y-axis plane by the mutual cooperation between control button
Any bending angle, fixed angle and direction operation in the course of surgery, and be subject to endoscope channel or accessory channel come it is auxiliary
Carry out moving operation is helped, reaches and preferably applies art effect.Performer in patient body-surface, incites somebody to action the negative plate docile of radio-frequency generator
Another cable is connected to handle electrode 11, and when the tissue of the cutter head in cutter head portion 3 and patient contacts, performer can trample hair
Raw device makes high-frequency current be conducted to cutter head portion 3 by the guide line 4 of the eyelet strip 6- conductor material of electrode 11- conductor material
Metal ball shaped electric knife component, and then be transmitted in the tissue being in contact with it, and be made up of human body and negative plate and conducting wire
One complete circuit, the high temperature of moment will be generated by applying art tissue, be allowed to that character changes or moment is gasified or heated
Rotten, it is cutting or coagulation that this, which depends on generator mode selected by performer,.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
