Abstract
The utility model relates to a radiotherapy particle endoscope implant, comprising an implantation needle and a catheter, the front end of the catheter is in a pointed-edge shape, the rear end thereof is an implantation needle interface, and a sleeve pipe is arranged outside the catheter; the radiotherapy particle endoscope implant is characterized in that: the point end of the sleeve pipe is provided with a targe shape, and a fine and soft material layer is arranged on the surface of the sleeve pipe; the radiotherapy particle endoscope implant can lead the radiotherapy particles to be directly injected in a tumor body under direct view of the endoscope, so as to carry out interventional therapy to local tumor of cavity visceral organs such as stomach and gullet; the radiotherapy particle endoscope implant has no hurt to the visceral organs and is easy to hold.
Description
Technical field
This utility model relates to the medical device technical field, is specifically related to a kind of radiotherapy particle scope implantation device.
Background technology
Radioactive particle is implanted in the tumor body, treatment for local tumor has better action, the particle implantation device of prior art is when implanting the chemicotherapy particle, must under the guiding of CT or B ultrasonic, carry out, complicated operation, equipment and technology requires high, and only can be used for the internal organs that percutaneous puncture arrives, for example liver, pancreas etc., hollow organs such as stomach, esophagus are then inapplicable.
Notification number: CN2848251, the Chinese patent literature of the day for announcing: 2006.12.20 discloses a kind of " radiotherapy particle scope implantation device ", comprise implant needle, conduit and hard sleeve, catheter proximal end is sharp bladed, the rear end is the implant needle interface, sleeve pipe is placed in the outside of conduit, and the implantation device of this kind structure can carry out interventional therapy to the local tumor of hollow organs such as stomach, esophagus.But the telescopic tip of this utility model is too straight, damages easily, and handle is too sliding, is difficult for holding.
Summary of the invention
The purpose of this utility model is can not adapt to the hollow organ interventional therapy, internal organs be damaged, are difficult for deficiency such as grippings easily at existing radiotherapy particle scope implantation device, provide a kind of and can adapt to the hollow organ interventional therapy, be difficult for to internal organs damage, a kind of radiotherapy particle scope implantation device of gripping easily.
The purpose of this utility model realizes by following technological means: a kind of radiotherapy particle scope implantation device, include implant needle and conduit, catheter proximal end is sharp bladed, the rear end is the implant needle interface, the outside of conduit also is provided with sleeve pipe, it is characterized in that: described telescopic tip is set to the targe shape, and telescopic surface also is provided with the soft material layer of one deck.
Described sleeve pipe and conduit are set to the flexible connected mode of spiral, and the length of conduit is greater than sleeve pipe.
The rear end of described conduit also is provided with handle, and described handle surfaces is provided with relief region.
Compared with prior art the utlity model has following tangible advantage: 1, this radiotherapy particle scope implantation device can directly inject the radiotherapy particle in the tumor body at direct view under endoscope, can carry out interventional therapy to the local tumor of hollow organs such as stomach, esophagus.2, this radiotherapy particle scope implantation device is difficult for internal organs are damaged, and is very easy to grip.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-implant needle, 2-conduit, 3-implant needle interface, 4-sleeve pipe, 5-handle.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment this utility model is described in further detail:
A kind of radiotherapy particle scope implantation device as shown in Figure 1, include implant needle 1 and conduit 2, catheter proximal end is sharp bladed, the rear end is an implant needle interface 3, the outside of conduit 2 also is provided with sleeve pipe 4, the tip of described sleeve pipe 4 is set to the targe shape, and the surface of sleeve pipe 4 also is provided with the soft material layer of one deck.Being provided with like this, is for fear of radiotherapy particle scope implantation device internal organs to be damaged, and is very easy to grip.
Described sleeve pipe 4 and conduit 2 are set to the flexible connected mode of spiral, and the length of conduit 2 is greater than sleeve pipe 4.The rear end of described conduit 2 also is provided with handle 5, and described handle 5 surfaces are provided with relief region.
This radiotherapy particle scope implantation device in use, under the direct-view of scope, operate, rotate the spiral knob, earlier implant needle 1 and conduit 2 are retracted in the sleeve pipe 4, give this radiotherapy particle scope implantation device then inward, like this, just can well prevent that the blade of conduit 2 from stabbing the minute surface or the biopsy pipe of scope, after the biopsy pipe by scope reaches focal zone, counter-rotation spiral knob, inwardly stretch out conduit 2 and implant needle 1, the radiotherapy particle is directly injected in the tumor body along implant needle 1.
In a word, this radiotherapy particle scope implantation device can directly inject the radiotherapy particle in the tumor body at direct view under endoscope, can carry out interventional therapy to the local tumor of hollow organs such as stomach, esophagus.
