Abstract
The utility model relates to a micro-invasive implanting type radiotherapy bag. The radioactive nuclear elements are introduced into the local part of the tumour under the condition of the minor invasion to the patient by utilizing the device. The utility model overcomes the disadvantages of other similar devices, not only the radiotherapy bag can be implanted into the head of the patient through the micro-invasive way, but also the radioactive nuclear elements can be gathered at the local part of the brain tumour. The device consists of a liquid reservoir, a duct and a medicine storing bag. The liquid reservoir is a hollow and flat sphere, which is connected with the duct. A plurality of pores are arranged at the tail end of the duct, and the tail end is wrapped through the medicine storing bag. Both the liquid reservoir and the duct are made of silica rubber, and a thin stainless steel gasket is lined at the bottom of the liquid reservoir. A liquid storage bag is made of soft and highly elastic natural latex film to be wrapped at the tail end of the duct and form an enclosed bag cavity. When the device is used, the tail end of the duct is firstly implanted into the cavity of the brain tumour with the three-dimensional directional technology, and then the liquid reservoir is fixed under the scalp at the appropriate place.
Description
Affiliated technical field
This utility model relates to and a kind of the cerebral tumor is carried out the medical treatment device of internal radiotherapy, can utilize this device, in that the patient is damaged under the minimum situation, radionuclide is imported tumor by local.
Background technology
Radionuclide is imported radiotherapy in the tumor by local, is one of most important method of the treatment cerebral tumor.To import the radionuclide of liquid state accurately in the cerebral tumor, need be by corresponding medical treatment device.The related device of using mainly contains two kinds at present, a kind of is the Ommaya capsule, this device can be implanted patient's head by the method for Wicresofts such as stereotaxis, but when in the cerebral tumor, injecting radionuclide by the Ommaya capsule, because catheter tip is open, radionuclide inevitably can spread in cerebral tissue, has not only reduced radiotherapy effect, also may cause damage to normal cerebral tissue.Another kind is an improved radiotherapy capsule on Ommaya capsule basis, and this device has installed the cecum that expands additional at Ommaya ductus bursae end, can accumulate in tumor by local through the radionuclide of its injection.But this radiotherapy capsule must be after opening intracranial tumour excision could the implantation tumour part, can not implant by the mode of Wicresoft, particularly can not be applied to be difficult to the functional areas tumor of excision, limited the application of this device.
The utility model content
This utility model has overcome the shortcoming of above-mentioned two kinds of devices, both can conduit be implanted patient's cerebral tumor part through the mode of Wicresoft, radionuclide through its injection can be accumulated in cerebral tumor part again, be applicable to the interior radiotherapy of the various cerebral tumors, especially the functional areas tumor treatment.
This device is made up of three parts: liquid reservoir, conduit and storage medicine bag.Liquid reservoir is hollow, oblate body, links to each other with conduit.The conduit latter end has several apertures.Whole conduit latter end is store the medicine bag parcel.Liquid reservoir and conduit are made by silica gel, and the liquid reservoir end liner is with thin stainless steel gasket.Reservoir is made by quality softness, the good natural emulsion thin film of elasticity, and the parcel catheter tip forms airtight blister cavities.
When using this device, should with horseley-Clarke technique catheter tip be implanted in the cerebral tumor tumor chamber earlier, in place liquid reservoir is fixed under the scalp then.In carrying out during radiotherapy, with the liquid radionuclide suction of 2ml syringe, the liquid reservoir the percutaneous puncture scalp under slowly injects the reservoir of far-end to nucleic through conduit, reaches the purpose of interior radiotherapy.
