Abstract
The present invention relates to a scalpel, which comprises a main body part and a cutting part, wherein the cutting part is in a linear structure, the diameter is from 10 to 1000 nm, and the length is from 1cm to 50cm. The linear structure is made of a carbon nanometer tube, or a carbon nanometer tube bundle, or a carbon nanometer thread, or a nanometer thread made of silicon nitride, a compound of boron, carbon and nitrogen, silicon carbide or gallium nitride, and the linear structure is preferred to be in a straight line shape, or in a spiral shape. The diameter of the scalpel provided by the present invention is far shorter than the size of blood vessels and neurons, so in the operation process, a patient does not bleed and has no pain.
Description
[technical field]
The present invention relates to a kind of scalpel, relate in particular to a kind of scalpel that is used to excise cancerous cell.
[background technology]
The means of treatment cancer have multiple, main Therapeutic Method that operative therapy, chemotherapy and X-ray therapy are arranged at present, in addition, also have gene therapy, immunotherapy etc., wherein wider also genus operative therapy, chemotherapy and the X-ray therapy of suitable application area.Operative therapy is to be applied to treat method for cancer the earliest, also is the first-selected therapy of present many early-stage cancer treatments, and most of early-stage cancer can reach the purpose of radical cure by the method for operation; Chemotherapy is to use the chemotherapy cancer, these medicines can suppress or kill cancer cell in the different phase of growth of cancer cells breeding, reach the purpose of treatment, at present, chemotherapy is mainly used in various types of leukemia and can't performs the operation and to the insensitive patient of radiotherapy; X-ray therapy is to kill the cancer born of the same parents to reach the purpose of treatment, to the better therapeutical effect of cancer tool of radiotherapy sensitivity, as Hodgkin, non-Hodgkin lymphatic cancer etc. with lonizing radiation; Wherein chemotherapy and X-ray therapy are except that treatment field own is limited, except that kill cancer cell, all can cause damage to the human normal cell in various degree during its treatment, produce a series of side effect, as cause patient's immunity degradation, easily bring out and infect and other complication, and infect patient's immunity is further descended with other complication, cause tumor recurrence, thereby, make the patient fear in seeking medical advice, and cause the state of an illness to be incured loss through delay, indirect causes therapeutic effect unclear.
Operative therapy is except that can't treating invasive and metastatic cancer, early-stage cancer there is higher cure rate with surgical removal, in addition, the healing cycle of operative treatment and medical expense are all low relatively, still be the main means for the treatment of cancer at present, but the deficiencies such as defective that operative therapy can bring pain, amount of bleeding is big and causes the patient body aspect to patient, the picture laryngeal carcinoma, the excision vocal cords can make patient lose the speech ability, be positioned at the skin carcinoma of eyelid or nose portion, operative treatment can influence patient's appearance.
For overcoming the deficiency of above-mentioned operation method, in recent years, various Minimally Invasive Surgerys begin to be widely used, Minimally Invasive Surgery is to open little otch about an about 1cm at patient's affected part, implant a micro catheter that has little operation Camcording system along this otch, by Camcording system the diseased region tissue being amplified tens times also projects on the TV monitor clearly, utilize Micro operating knife with excision of the lesion again, Minimally Invasive Surgery is reducing patient's pain, is reducing and positive meaning is arranged aspect hemorrhage, but still can not avoid deficiency hemorrhage and patient's pain fully.And alleviate patient's pain, reduce the topmost mode of bleeding is the size that reduces operation tool, improves the intensity of operation tool simultaneously.
In view of this, provide a kind of and be used to excise cancerous cell and operation process does not have pain, bloodless scalpel is real be necessity
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of scalpel that is used to excise cancerous cell, and uses the operation process of this scalpel not have pain, does not bleed.
For addressing the above problem, the present invention discloses a kind of scalpel, and it comprises a main part and a cutting part, and this cutting part is a linear structure, and the diameter of this linear structure is 10nm to 1000nm, and length is 1cm to 50cm.
This cutting part is a CNT, or carbon nano-tube bundle.This CNT is generally multi-walled carbon nano-tubes, pulls out in the carbon nano pipe array that carbon nano-tube bundle can make by chemical vapour deposition technique to make.This cutting part also can be selected carbon nanocoils for use, or the nano wire of being made by silicon nitride, boron carboritride, carborundum or gallium nitride.This cutting part is preferably linear, also can be spiral type.
Because the size of blood vessel is generally 10 μ m to 1mm, the size of neurocyte is about 10 μ m to 500 μ m, and the scalpel diameter only is 10nm to 1000nm, much smaller than blood vessel and neural size, its chopping and operation process are not bled no pain so scalpel is easy to pierce through cancerous cell.
[description of drawings]
Fig. 1 is the sketch map that penetrates into cancerous cell with scalpel of the present invention.
[specific embodiment]
See also as Fig. 1, the scalpel 30 that is used to cut cancerous cell 10 of the present invention comprises a cutting part 31 and a main part 32.Cutting part 31 is used for combining with cancerous cell 10, and its chopping is micro-fragment.Above-mentioned cutting part 31 is a linear structure, and the diameter of this linear structure is about 10nm to 1000nm, and length is about 1cm to 30cm.
This cutting part 31 is a CNT, or carbon nano-tube bundle.This CNT is generally multi-walled carbon nano-tubes, pulls out in the carbon nano pipe array that carbon nano-tube bundle can make by chemical vapour deposition technique to make.This cutting part 31 also can be selected carbon nanocoils for use, or by silicon nitride, the boron carboritride, carborundum or gallium nitride are made nano wire.This cutting part 31 is preferably linear, also can be spiral type.
When utilizing above-mentioned scalpel 30 to carry out the cancerous cell cutting, can monitor different organs or focus by tomoscan and nuclear magnetic resonance, NMR earlier, or carry out target spot by spiral CT and dissect location, syncaryon magnetic resonance, accurate Calculation, the position of making cancerous cell 10 and size.And then scalpel 30 penetrated into affected area, and cancerous cell 10 choppings are micro-fragment, cancerous cell 10 is killed.Because the size of blood vessel 20 is generally 10 μ m to 0.5mm, the size of neurocyte (figure does not show) is about 10 μ m to 500 μ m, the diameter of scalpel 30 only is 10nm to 1000nm, much smaller than blood vessel 20 and neural size, so scalpel 30 is easy to pierce through cancerous cell 10 with its chopping, and operation process is not bled, no pain.
This scalpel 30 can be applicable to the brain cancer, skin carcinoma, and treatment and ophthalmologic operations such as hepatocarcinoma are in the operation on heart.In addition, the present invention's scalpel also can be used for other cutting operation.
