Description
Technical field
The invention is related to a kind for the treatment of of solid tumor device, and especially a kind of entity tumor based on ablation is cut to pieces out
Therapeutic device.
Background technique
In recent years, China's parenchymal viscera tumour such as lung cancer, liver cancer, kidney, breast cancer, prostate cancer, thyroid cancer etc.
Incidence increases year by year, and treatment method preferred operation excision mostly brings huge wound to body, can usually cause very much
It is also relatively long to restore the period for complication, and while making a definite diagnosis has been mostly advanced stage, loses the chance for removal of lesions of performing the operation.Part disappears
Melting technology has the characteristics that wound is small, curative effect is clear, treat some patients that cannot go operation removal of lesions can also
Chance, be used widely in recent years, therefore importance of the local ablation therapy in the complex treatment of entity tumor is increasingly
It is promoted.In addition, both at home and abroad many Consensus of experts think: melt small liver cancer, diagnosis of small renal cell carcinoma treatment in terms of curative effect and operation cut off
It is close, it is considered to be one of small liver cancer, diagnosis of small renal cell carcinoma radical treatment means, therefore, tumour ablation treating at home and abroad obtains fast
Hail exhibition.Nevertheless, ablation needs are implemented in the specific situation of pathological diagnosis, and the most common approach of clear pathology
It is percutaneous transthoracic needle biopsy, however, progress fine needle aspiration biopsy is pretty troublesome sometimes, it some times happens that bleeding, tumor planting, also have
The false negative that tumor tissues can not be obtained occurs.In order to solve this problem, there is researcher using percutaneous immediately after ablation
CNB can be improved the diagnosis success rate of CNB, especially thermal ablation techniques and control in a certain range in temperature, and cancer cell is in high temperature
One progressive apoptotic process of experience under effect, the regular hour is interior there is no destroying after ablation for nuclear structures,
Cellular morphology keeps good, is confirmed in the tumor specimen of the underwent operative excision obtained immediately or in 3 days after ablation.Therefore
Pathological diagnosis is not influenced, genetic test, genetic analysis are nor affected on；Second, the blood flow of tumour and living cells are less after ablation,
Row CNB inspection is bled profusely to be reduced with tumour spread risk chance of occurrence.Therefore, percutaneous CNB obviously drops immediately after ablation
The low incidence of the complication such as bleeding and tumor planting is increasingly paid attention to by clinic.
In addition, ablation often causes tumour ablation to be not thorough because heat sink drop occurs for the factors such as blood flow, still there is remaining active
Cancer cell is possible and leads to tumor recurrence and transfer, this drops some possible little tumour patient's curative effects for obtaining healing significantly
It is low.To further increase curative effect, it is necessary to it designs a kind of entity tumor based on ablation and cuts therapeutic device out to pieces, it can be effective
It improves tumour ablation curative effect, reduce the treatment pain of tumor patient, and be conducive to patient's recovery.

On the upper side of shell 9；The one end for swinging gag lever post 51 is provided with sliding limit casing 50 to be set in and be adjusted axially screw rod 47
On；It is provided with insulating layer on the outer wall of ablating electrode bar 6, and is arranged at intervals with three limit disks 49 in upper end；It is putting
The other end of dynamic gag lever post 51 is provided with the Horizontal limiting notch 52 for being buckled on limit disk 49；And in Horizontal limiting slot
The upper and lower sides trough rim of mouth 52 is equipped with U-lag mouth convenient for being snapped on ablating electrode bar 6；Two equal screw threads of limit fixture nut 53
It screws to be mounted on and be adjusted axially on screw rod 47, and be located at the two sides up and down of sliding limit casing 50.Using being adjusted axially spiral shell
Bar 47 swings three limit disks 49 being arranged on gag lever post 51, two limit fixture nuts 53 and ablating electrode bar 6, energy
Enough axial positions to ablation electrode stem 6 are adjusted.
The invention provide the entity tumor based on ablation cut to pieces out therapeutic device when in use the step of it is as follows:
Ablation is carried out first, and 26 abutting joint of ends screw column realizes electrical connection on lower docking threaded hole 44, will
Horizontal limiting notch 52 is buckled on the limit disk 49 of downside, is adjusted using two limit fixture nuts 53 and is swung gag lever post 51
Height, thus press ablating electrode bar 6 make four radio frequency needles 25 lower end stretch out arc through hole 46 outside, be pierced into tumour in
Portion, then Electric plug with shutter 48 is connected into ablation needle signal source and carries out ablation；After the completion of ablation, Electric plug with shutter 48 is disconnected
Ablation needle signal source, swing gag lever post 51 and discharge ablating electrode bar 6, four radio frequency needles 25 contract under the action of springing back pressure spring 34
In arcing back shape through hole 46；The Horizontal limiting notch 52 for swinging gag lever post 51 is buckled on the limit disk 49 of medial side again,
So that ends screw column 26 is in intermediate vacant state, work convenient for next step bit；
Drill bit insertion is carried out again, is acted on using negative-pressure adsorption, by 2 lower end of cutting pipe and its cutting triangular blade 4 to tumour
Tissue adsorptions are fixed, and drill bit positional dissection is convenient for, and the anti-bad positioning of sliding stop drill bit starts drill bit driving motor 11, tapered end
First 30 pierce in tumour under the action of screw blade 32, at this time drill bit mechanism insertion tumour in, eight bending tool sections 29 close to
Tumour；
Again by 26 abutting joint of ends screw column on internal screw thread 41, electrical connection is realized, so that eight bending tool sections 29
RF ablation signal is received to melt drill hole inner wall tumor tissues；After the completion of ablation, restart drill bit driving electricity
Horizontal limiting notch 52 is buckled in after circumgyration incision by machine 11 by eight 29 pairs of the bending tool section internal circumgyration incisions that carry out
It on the limit disk 49 of side, is screwed by limit fixture nut 53 to increase the insertion depth of ablating electrode bar 6, to increase each
The bending degree of a bending tool section 29 increases drill bit cutting diameter；It is connected after the completion of this cutting, then by Electric plug with shutter 48
Ablation needle signal source carries out next step ablation；
In above-mentioned steps, ablation and circumgyration incision are alternately, can gradually to be cut in this way, so that cutting
Diameter becomes larger, and meets the ablation cutting of major diameter tumour；When drilling rod 5 is in rotation status, needs to pull out to be electrically connected and patch
The ablation needle signal source inserted on first 48；When eight bending tool sections 29 are in ablation state, No starting drill bit driving motor
11 carry out cutting driving.
After the completion of ablation and cutting are alternately accomplished the cutting of whole tumor tissues, the Horizontal limiting notch of gag lever post 51 is swung
52 are buckled on the limit disk 49 of medial side, so that ends screw column 26 is in intermediate vacant state, eight of drill bit mechanism
It bends tool section 29 and pushes the sliding lesser bending degree of recovery on sliding sleeve 28 in elastic reaction；Again by suction function, pass through negative pressure
Tissue after chopping separation is sucked out connecting tube 38 along cutting pipe 2；Again by rotation adjusting screw rod 20, so that 5 lower end of drilling rod
Drill bit mechanism retract cutting pipe 2 in, while start cutting driving motor 10 using cutting triangular blade 4 to drill bit mechanism periphery
Tissue carry out cutting separation.
