The therapeutic machine consists of tubular source applying device, shielding source bank, source conveying conduit connected between the said device and bank, souce inside the conduit, conveying cable connected to the souce, two-way driving machanism driving the conveying cable and control console connected to the driving machanism. The said therapeutic machine ensures that the operation personnel works in safe environment without radioactive rays and results in accurate positioning and high cure effect.
Description
The present invention relates to a kind of therapy apparatus that utilizes radioactive source to treat hyperplasia of prostate.
The open CN1078653A of Chinese patent discloses a kind of " therapy instrument for hyperplastic prostate ", by the medical stick that has sulculus be bonded in weak radiator beta-ray in the medical stick sulculus and sleeve pipe that cover is enclosed on the medical stick is constituted.Should rod during treatment insert, utilize the β ray of the radioactive source emission on the medical stick to penetrate rectal wall and act on prostate from patient's anus, make it to be subjected to ionizing radiation and atrophy to reach therapeutic purposes.This therapeutic instrument is a kind of simply bar-shaped, and radioactive source directly is bonded on the barred body earlier, and the medical worker can be subjected to its irradiation when operation, make it to lack the security, can not operate at leisure, thereby easily cause the location inaccurate, treatment time and effect all can not get ensureing.
The objective of the invention is to overcome the above-mentioned shortcoming of aforementioned therapies instrument, provide a kind of operator of making not to be subjected to the radioactive source rear mounted therapeutic machine for prostate hyperplasia of radioactive source irradiation.
The rear mounted therapeutic machine for prostate hyperplasia of realizing purpose of the present invention by tubulose apparatus for wave-energy source, protected type storage storehouse, source, the transmission cable that is connected in radioactive source transmitting catheter between protected type storage storehouse, source and tubulose apparatus for wave-energy source, is arranged on radioactive source in the transmitting catheter, join with radioactive source and driving transmits the bi-directional drive mechanism that cable moves and the control station that is connected in bi-directional drive mechanism is constituted.Its control station and other parts are installed in respectively in control room and the therapeutic room during use, before the treatment beginning, radioactive source is in the protected type storage storehouse, source, whole therapeutic room is in the security context of no ray, the staff can insert apparatus for wave-energy source and be positioned requiring in rectum or the urethra at leisure and leave therapeutic room again behind the position and operate to the control room, promptly make the bi-directional drive mechanical operation by control station, drive the motion of transmission cable radioactive source is moved in the apparatus for wave-energy source along transmitting catheter from storage storehouse, source, make the ray of radioactive source radiation finish treatment in prostate by the medical window radiation effects of apparatus for wave-energy source.After treatment finishes, can make the revolution of bi-directional drive mechanism by control station again, radioactive source is recovered in the storehouse, storage source shield folding and unfolding.This moment, therapeutic room was in heavily again in the security context of no radiation, and the medical worker then can enter therapeutic room relievedly and remove apparatus for wave-energy source.Be not subjected in the complete environment of roentgenization thereby realized that the medical worker is operated in, so that treat the purpose of operation, assurance curative effect at leisure in high quality.
For further improving therapeutic effect, can select for use
137Cs is as the radioactive source of this therapy apparatus.Utilize the daughter of its decay
1.37mThe gamma-ray penetration power of Ba emission far is better than Beta-ray this character, its dosage that acts on prostata tissue is increased greatly, can guarantee simultaneously the tolerance dose of the radioactive dose of rectum (or urethra) again, when improving curative effect, make side effect littler far below safety.
Consider that the treatment hyperplasia of prostate can realize that the apparatus for wave-energy source correspondence of this therapy apparatus is provided with two kinds on urethra type and rectum type from urethra and two approach of rectum.Wherein, rectum type apparatus for wave-energy source by a lucite tube, be arranged on the shield that leaving the treatment window on the lucite inside pipe wall, be located at the thread bush of lucite tube opening and the wedge-like clamp jaw that is located in the corrugated tubing is constituted.End with transmitting catheter during use puts in thread bush and the lucite tube, utilizes the inner surface of thread bush that clamp jaw is clipped in and realizes on the catheter body being connected.Radioactive source then can enter into the treatment window place of apparatus for wave-energy source along transmitting catheter.Ray then can only radiate out from the treatment window, and other direction then conductively-closed body shields, and has guaranteed that other organ is avoided unnecessary irradiation in the body.
And urethra type apparatus for wave-energy source can be made of a soft tubular body and an adapter sleeve that is connected on the soft body simply, also can be to execute in the rectum type to remove shielding slab in the source and constitute.
On described thread bush, scale mark can be set, fix to make things convenient for the doctor when apparatus for wave-energy source is put into patient's rectum, to find treatment window aligning prostate position accurately.
It is that 149 ℃, length are that the fan-shaped window of 30mm is advisable that described treatment window can be made as central angle.The treatment window of this form is easy to obtain best therapeutic effect.
Still thread bush can be designed to a joint form that connects with transmitting catheter, so that replacing of apparatus for wave-energy source, cleaning etc.
Advantage of the present invention is that operator are operated in the security context of no ray, guaranteed operator physical and mental health, can accurately locate at leisure, guarantee the radiotherapy time and curative effect guaranteed.
Provide embodiment below in conjunction with accompanying drawing
