Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically is to be used for preventing the device that tumor spreads after the bone tumor biopsy.
Background technology
During the bone tumor biopsy, need to puncture to bone tumor earlier, can stay next needle track after getting biopsy, at present, if the needle track that stays does not deal with, the tumor cell in the bone tumor will flow to around the puncture orifice by needle track, forms the tumor diffusion, the influence treatment.And also do not have special use to come the shutoff needle track at present, thereby prevent the device of tumor diffusion.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of being used for to prevent the tumor disperser after the bone tumor biopsy, but the needle track that stays after the biopsy is got in its shutoff, prevent that tumor cell from passing through the needle track local diffusion.
In order to address the above problem, the present invention is by the following technical solutions: a kind of being used for prevents the tumor disperser after the bone tumor biopsy, comprise being used for the shutoff main body that puncture needle track after the biopsy is got in shutoff, described shutoff main body is made by the suction expandable material, and outer surface is provided with screw thread; One end of shutoff main body is the shutoff end, and the maximum gauge place of shutoff end is less than the diameter of puncture needle track; The other end of shutoff main body is the operating side, and the operating side is provided with jack or the inserting handle that can operate spanner along the axial grafting of shutoff main body; The maximum gauge place of operating side is greater than the diameter of puncture needle track; The middle part of shutoff main body is the inner concavity joint pin, and is rounding off between this joint pin and shutoff end, the operating side; Be coated with the cancer therapy drug layer on the described shutoff end.
Bone tumor is punctured, after getting biopsy, the shutoff end of shutoff main body is placed in the puncture orifice of needle track, then an operation spanner is plugged on the operating side of shutoff main body, rotating spanner, the shutoff main body slowly screws in the needle track by screw thread, expands behind the water in the shutoff absorbent body blood, thereby, prevented that tumor cell from causing local diffusion and transfer by the needle track outflow with the needle track shutoff.
As further technical scheme of the present invention: after this is used for the bone tumor biopsy, prevent the tumor disperser, be provided with a through hole vertically in the described shutoff main body, be plugged with conduit in this through hole, wherein an end of conduit stretches out in outside the operating side and the end is provided with seal cover; The other end of conduit stretches out in the shutoff end and be provided with a plurality of medicine outlet holes on the sidewall of end.
Like this, for bone tumor that can't excision, insert the shutoff main body in the needle track after, the end that stretches out the operating side of conduit is placed outside the skin, this end seal cover sealing is kept somewhere standby, makes things convenient for the injection chemotherapeutics of repeated multiple times.Behind clear and definite biopsy pathology result, select responsive chemotherapeutics to carry out local high-dose chemotherapy, chemotherapeutics can be injected in the tumor by conduit.The medicine outlet hole of end of conduit is arranged on the sidewall, helps the diffusion of medicine in tumor, has increased therapeutic effect.
The invention has the beneficial effects as follows: the needle track that punctures and stay after the biopsy is got in its shutoff, can prevent that tumor from causing local diffusion and transfer around needle track flows out to puncture orifice, and complete tumor resection helps performing the operation; Bone tumor patient that can not excision for metastasis is arranged, outside decapacitation prevents local diffusion and shifts, also can utilize conduit to carry out the chemotherapeutics injection repeatedly of local multiple spot after the biopsy condition is provided, thereby improve local symptom for getting, mitigate the disease, injection operation is simple and convenient.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one,
Fig. 2 is the structural representation of the embodiment of the invention two,
Among the figure: 1 shutoff main body, 2 shutoff ends, 3 operating sides, 4 jacks, 5 joint pins, 6 cancer therapy drug layers, 7 conduits, 8 medicine outlet holes, 9 seal covers.
The specific embodiment
Embodiment one: as shown in Figure 1, this is used for preventing the tumor disperser after the bone tumor biopsy, comprises being used for the shutoff main body 1 that puncture needle track after the biopsy is got in shutoff, and described shutoff main body 1 is made by the suction expandable material, and outer surface is provided with screw thread.
One end of shutoff main body 1 is a shutoff end 2, and the maximum gauge place of shutoff end 2 is less than the diameter of puncture needle track.Be coated with cancer therapy drug layer 6 on the shutoff end.
The other end of shutoff main body 1 is operating side 3, and the operating side is provided with the hexagon jack 4 that can operate spanner along the axial grafting of shutoff main body; The maximum gauge place of operating side 3 is greater than the diameter of puncture needle track.Jack also can have the prism-shaped inserting handle to replace inserting handle and operating side one.But the relatively good processing of jack, so preferred jack.
The middle part of shutoff main body 1 is an inner concavity joint pin 5, and is rounding off between this joint pin 5 and shutoff end 2, the operating side 3.
Bone tumor is punctured, after getting biopsy, the shutoff end 2 of shutoff main body is placed in the puncture orifice of needle track, then an operation spanner is plugged in the jack 4 of operating side, rotating spanner, the shutoff main body slowly screws in the needle track by the screw thread of its outer surface, expands behind the water in the shutoff absorbent body blood, thereby, prevented that tumor cell from causing local diffusion and transfer by the needle track outflow with the needle track shutoff.
Can establish high scale on the spanner of its use, so that grasp the length that the shutoff main body screws in.
But this device is applicable to the bone tumor of excision, when cutting bone tumor, together the cutting-out of shutoff main body is got final product.
Before placing the shutoff main body, the local hemorrhage when getting biopsy can adopt the control of electric coagulation hemostasis device, reduces operation risk.Also can utilize microwave therapy equipment to the tumor deactivation of puncture orifice with carry out partial tumor deactivation, place and get tumor by local diffusion after the biopsy.Electric coagulation hemostasis device, microwave therapy equipment are prior art.
Embodiment two: as shown in Figure 2, this embodiment and embodiment one difference are, are provided with a through hole in the shutoff main body vertically, are plugged with conduit 7 in this through hole, and wherein an end of conduit stretches out in outer and end, operating side 3 and is provided with seal cover 9; The other end of conduit stretches out in shutoff end 2 and be provided with a plurality of medicine outlet holes 8 on the sidewall of end, and each medicine outlet hole preferably is provided with according to differing heights, different directions distribution.
This device be applicable to can't excision bone tumor.
After inserting the shutoff main body in the needle track, keep somewhere in skin outside standby with seal cover 9 sealings an end that stretches out operating side 3 of conduit.Behind clear and definite biopsy pathology result, when selecting responsive chemotherapeutics to carry out local high-dose chemotherapy, open seal cover, chemotherapeutics can be injected in the tumors by conduit 7.The medicine outlet hole 8 of end of conduit is arranged on the sidewall, and each medicine outlet hole helps the diffusion of medicine in tumor, the increase therapeutic effect so preferably according to differing heights, different directions distribution setting.
