Abstract
The invention discloses an implanted intraspinal therapeutic device. The implanted intraspinal therapeutic device comprises a liquid storage bag (1) and a connector (5) arranged on the liquid storage bag (1). The connector (5) is connected with one end of a delivery tube (2) and the other end of the delivery tube (2) extends into an intraspinal lesion zone and is connected with a therapeutic tube (3) implanted in the lesion zone. A liquid hole (4) is formed in the therapeutic tube (3). The implanted intraspinal therapeutic device is implanted below the spinal canal membrane of a tumor or a spinal cord injury portion or a syringomyelia portion or the lesion zone inside the spinal canal, the liquid storage bag is located below the epidermal tissue of the spinal column, a therapeutic agent is injected into the liquid storage bag, the therapeutic agent flows into the therapeutic tube implanted in the spinal column zone through the delivery tube connected with the liquid storage bag, the therapeutic agent is diffused in the disease zone in the diameter direction through the liquid hole in the therapeutic tube, and therefore a disease can be well treated. Meanwhile, the implanted intraspinal therapeutic device also serves as an extracting device used for extracting dropsy of the syringomyelia portion and the therapeutic agent when adverse reaction occurs in the therapeutic process, the dropsy or the therapeutic agent enters the therapeutic tube through the liquid hole and is delivered to the liquid storage bag through the delivery tube and then extracted out.
Description
Technical field
The present invention relates to Intraspinal diseases treatment field, be specially a kind of chemotherapy, radiotherapy and Biotherapeutics of being applicable to, for the implanted canalis spinalis internal therapy device of the Intraspinal diseases such as intraspinal tumor, spinal cord injury, spinal cord empty.
Background technology
In canalis spinalis, in intramedullary spinal tumor, spinal cord glioma accounts for center-stage, and its sickness rate can account for the more than 80% of intramedullary spinal tumor, and along with the raising of malignant brain tumor curative effect, long-term survivors increases, and canalis spinalis intracavity is sent out case also to be increased.In addition, due to diagnostic techniques raising in recent years, especially by application MRI, in silent spinal cavity, sending out case can early discovery, this morbid state is generally diffuse growth, their clinical characters and onset form have many similarities, but therapeutic strategy and mode are not quite similar, except operative treatment, remaining the still needing of spinal cord glioma wanted further local radiation treatment, chemotherapy and Biotherapeutics etc., effectively to control recurrence and the growth of tumor, these topical therapeutics can be avoided blood brain barrier, can reduce the side effect of whole body again, also can improve curative effect simultaneously.
Spinal cord injury brings health and psychological grievous injury ，Hai Huidui entire society to cause huge financial burden not only can to patient, and incidence rate presents the trend increasing year by year.The extensive concern that the topochemistry treatment of repairing for spinal cord injury nerve and Biotherapeutics (especially cell transplantation) are subject to current medical circle.
Spinal cord empty is to expand because various congenital or acquired dispositions cause producing carrying out property myelopathic spinal cord hole sample, and clinical manifestation is segmental, dissociated sensory disturbance, segmental amyotrophy and conductive beam motion, sensation and local malnutrition.In operative drainage cavity, the liquid of abnormal perfusion and the reason that elimination causes spinal cord empty are main purpose and method, and in cavity, neural stem cells transplantation is that main Biotherapeutics is considered to promising important method.
Topochemistry treatment, radiotherapy and the Biotherapeutics etc. of the Intraspinal diseases such as current intraspinal tumor, spinal cord injury, spinal cord empty all lack corresponding local canalis spinalis internal therapy device.Therefore, provide a kind of and chemotherapy, radiotherapy and Biotherapeutics thing directly can be invested in to Spinal Diseases region, make the patients such as intraspinal tumor, spinal cord injury, spinal cord empty obtain desirable treatment, this is the object of declaring internal therapy device in canalis spinalis.
Summary of the invention
The invention provides a kind of simple in structurely, easy to use, and the therapeutant of chemotherapy, radiotherapy and Biotherapeutics etc. directly can be invested in to the canalis spinalis internal therapy device in disease region.
Implanted canalis spinalis internal therapy device, comprises reservoir 1, is arranged on the union joint 5 on reservoir 1, one end of union joint 5 connecting conveying pipes 2, the other end of carrier pipe 2 extends to intraspinal lesion region, is connected with the treatment tube 3 in being implanted in lesion region, is provided with liquid hole 4 in treatment tube 3;
Described reservoir 1 is arranged under the epidermis after back;
Described union joint 5 is arranged on the bottom or sidewall of reservoir 1;
The large small-bore in the liquid hole 6 arranging in described treatment tube 3 is different, minimum apart from 4 apertures, liquid hole that carrier pipe 2 and treatment tube 3 junctions are nearest, to 4 apertures, Chu Ye hole that are connected with treatment tube 3 away from carrier pipe 2, increases gradually;
The link of described union joint 5 is provided with the fixed chuck 6 that is cambered surface;
Described liquid hole 4 is that staggered stereo structure is distributed on the tube wall for the treatment of tube 3;
Described treatment tube 3 is arranged in spinal cord or under spinal cord dura mater;
Described carrier pipe 2, for not pressing off pipe, is provided with many protruding protruding ribs 7 in pipe.
positive beneficial effect:the present invention is implanted to intraspinal tumor, spinal cord injury, or spinal cord empty place, and reservoir is positioned at the subcutaneous place of ridge, by carry out the injection of therapeutic agent in reservoir, therapeutic agent enters in the canalis spinalis that is implanted in back region through the carrier pipe being connected with reservoir, therapeutic agent is diffused in disease region by the liquid bore dia being arranged in treatment tube, can treat local Intraspinal diseases, the extracting device of therapeutic agent when simultaneously the present invention also can be used as and occurs untoward reaction in the hydrops of spinal cord empty and therapeutic process, the logical liquid pass hole of hydrops or therapeutic agent enters treatment tube, in carrier pipe is delivered to reservoir, then be extracted out.The present invention, in therapeutic process, can recycle, and has reduced the wasting of resources, has reduced treatment cost, also to patient, reduces wound simultaneously.
