In on two pass joints 32.Using the combination of above-mentioned fixing sleeve 31, two pass joints 32 and nut 33 can make in incision knife by its
The pipeline of one through-hole is fixedly secured, and increases the stability and torsional strength of pipeline.Injection-tube 4 is installed in loose slot 13, is infused
It penetrates one end that pipe 4 is located at outside loose slot 13 and is fixed with female Luer 41, female Luer 41 can be used for connecting syringe.Cutter head 92
With through its second internal through-hole, syringe needle 91 is fixed in the second through-hole, insulation sleeve is installed in the end of outer tube 7
71, heat-shrink tube 6 is cased in outer tube 7, and spring hose 52 is installed in heat-shrink tube 6, spring hose 52 is fixed on limit fastener tube
61,61 other end of limit fastener tube connects cutter head 92 and passes through insulation sleeve 71.
Hereinafter, the installation situation of incision knife gut line is described in detail with reference to the accompanying drawings.
As shown in Figure 4 and Figure 5, it is connected between injection-tube 4 and boost tube 51 with fixing pipe 42, electricity is passed through by fixing pipe 42
Pole 23 and fixation be contacted on electrode 23, the boost tube 51 pass through connector 3 first through hole.When sliding block 2 is along loose slot 13
When movement, boost tube 51 is driven to move, and to guarantee that coagulation function, boost tube 51 and fixing pipe 42 use conductive material.?
Protecting pipe 8 is fixedly installed in the opening of nut 33, the effect of protecting pipe 8 is to protect its internal pipeline.
As shown in Figure 6 and Figure 7, boost tube 51 extends downwardly rear one end and is fixed with spring hose 52, and spring hose 52 uses
Stainless steel material needs the heat-shrink tube 6 in 52 outer cover of spring hose since spring hose 52 has radially bending characteristic, from
And guarantees spring hose 52 and bending deformation do not occur.Outer tube 7, and above-mentioned spring hose 52 and pyrocondensation are installed in protecting pipe 8
Pipe 6 is placed in outer tube 7.Limit fastener tube 61 is installed in the other end of spring hose 52, limit fastener tube 61 is for connecting
Spring hose 52 and cutter head 92 are equipped with insulation sleeve 71 in the end of outer tube 7, and the second through-hole inside cutter head 92 is fixed with syringe needle
91, cutter head 92 passes through insulation sleeve 71 and exposes outside entire incision knife.Spring hose 52 is for conducting the sliding of sliding block 2 to cutter head
On 92, to move in the axial direction with dynamic cutter head 92, the function of stretching out with retraction outer tube 7 is realized, meanwhile, spring hose 52 has
There is contraction stretching characteristic, when cutter head 92 resists or cuts tissue, play certain buffer function, avoids incised wound tissue.High frequency
For equipment after connection electrode 23, electric current passes through boost tube 51, spring hose 52, limit fastener tube 61 and the conduction of cutter head 92 to human body
And be formed into a loop, therefore, above-mentioned is conductive material；Simultaneously because outer tube 7 uses insulating materials.One is installed in 7 end of outer tube
Insulation sleeve 71 is to completely cut off cutter head 92 and outer tube 7, and when cutter head 92 extends downwardly, limit fastener tube 61 moves downward therewith, limits
Position fastener tube 61 can resist the upper surface of insulation sleeve 71 to prevent cutter head 92 from continuing to stretch out, and play position-limiting action.Meanwhile cutter head
92 923 diameter of cutting part should be greater than the aperture of insulation sleeve 71, so that cutter head 92 be prevented to be entirely retracted in insulation sleeve 71.
As shown in figure 8, cutter head 92 includes interconnecting piece 922 and cutting part 923, wherein have a rotary table inside cutting part 923
Through-hole 921, it acts as when cutter head 92 resists tissue surface, rotary table through-hole 921 can be tissue and swell one bulge of formation naturally,
It is injected to which smaller power can be used that syringe needle 91 is inserted into tissue, to reduce the injury to tissue.
The application method of the incision knife the following steps are included:
(1) electrode 23 is connected into high-frequency apparatus, syringe, which is pumped into, to be needed the liquid injected and connect female Luer 41, and same
Time shift movable slider 2 makes 92 retraction of cutter head to 1 upper end of sliding rail frame；
(2) cutter head 92 is inserted at the tissue that need to be cut by pincers road, opens high-frequency apparatus, sliding block 2 is slid into sliding rail
1 lower end of frame carries out coagulation to stretch out cutter head 92；
(3) mobile sliding block 2 makes 92 retraction of cutter head to 1 upper end of sliding rail frame, and pressing makes to be infused at the insertion tissue of syringe needle 91
It penetrates, when tissue bump height reaches requirement, sliding block 2 is slid into 1 lower end of sliding rail frame and is cut to stretch out cutter head 92.
When needing repeatedly cutting, human body is completely exfoliated to make that tissue need to be cut in repeatable step (2), (3).
The above is only the preferred embodiment of the present invention, not thereby limits the patent protection of the utility model
Range, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in it
