The device working principle is needed to plan the route of knit stitch, be simulated, to formulate before actually acupuncture treatment
A set of optimal knit stitch route out, secondly, to guarantee that implant needle is had an acupuncture treatment by preset route when practical acupuncture treatment, for this purpose, I
Positioned by visible laser, as long as in knit stitch guarantee implant needle have an acupuncture treatment along the light of visible laser
So that the route of acupuncture treatment is identical as projected route, in use, first pass through nuclear-magnetism or CT scan tumour, obtain tumour shape and
The faulted scanning pattern of position, and the data packet of multiple faulted scanning patterns is transferred in medical science modeling software, such as Mimics.So
The data three-dimensional of all faulted scanning patterns is modeled by Mimics system afterwards, obtains the 3D structure chart of patient tumors target area.It should
Structure chart editable and include complete human body surface structure, consequently facilitating determining that anchor point establishes coordinate in human body surface
System.Then the three-dimensional modeling data packet built up is transferred to progress particle layout in TPS system.By three in TPS system
The human body surface of dimension module determines anchor point and makes coordinate system, while determining total particle dose, and obtain particle cloth inning
Amount and position.Wherein the location information is the coordinate value in the coordinate system of foundation, is being directed to its number of particles and position again
Determine needle track.Finally all particle positions data obtained in tps system and needle track data are output to and control the angle offset
In the control system of device.In actual operation, the anchor point having determined can be found in corresponding patient human skin surface,
And reference axis is determined by crossing, generally using the vertical line of vertical direction as Z axis, so that control system turns the position coordinates of input
The time of control motor rotation is turned to, when being implanted into particle, how particle is accurately implanted to presumptive area is most
Therefore problem to be solved will not only consider the offset of angle in contact pin, it is also contemplated that the error of depth, we pass through can
See that laser is positioned, to guarantee that needle tubing 3 can be avoided the error of angle when penetrating, secondly, auxiliary by laser ranging simultaneously
The control for carrying out axial depth is helped to obtain shape and the position of tumour in use, first passing through nuclear-magnetism or CT scan tumour, then

The depth of tumour out, then corresponding scale is slided into along needle tubing 3 by limited block 4, so that the depth that penetrates of needle tubing 3 is controlled, then
It will be seen that laser and range laser are arranged in parallel, and are radiated at human body surface along the path of knit stitch, by the remotely located cap of needle tubing 3
1 one end is set to the human body surface of visible laser irradiation, then the irradiation for making the positioning groove 8 of positioning cap 1 also be located at visible laser
Path, the at this time axis of needle tubing 3, the axis of main chamber pipe 2 and the axis of positioning cap 1 are respectively positioned on the exposure pathways of visible laser, protect
It demonstrate,proves positioning groove 8 to be in always on the exposure pathways of visible laser, while needle tubing 3 is inserted into human body, needle tubing 3 is along visible at this time
The projected route of laser is had an acupuncture treatment, and since range laser and visible laser are arranged in parallel, range laser is radiated at feedback loop 7,
After under needle tubing 3 to predetermined depth, limited block 4 is exactly in contact with human body, while the signal that range laser will test is prompted,
Acupuncture treatment is completed, and seeds implanted is then carried out, and opens sealing cover 6, the particle being implanted into will be needed to be put into feeding cylinder 5, particle passes through again
Main chamber pipe 2 enters needle tubing 3, to reach presumptive area, multiple particles can also be put into feeding cylinder 5 simultaneously, then by turning
Fixed handle 15 makes shaft 13 that cutting plate 14 be driven to rotate, and particle is transported to main chamber pipe 2 one by one and enters pre-determined bit along needle tubing 3
It sets, completes implantation；When particle has in needle tubing 3 to get stuck, positioning cap 1 is removed, particle is pressed by feeding mechanism and is made a reservation for
After the completion of implantation, needle tubing is taken out for region.
The utility model is not limited to above-mentioned optional embodiment, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, making any variation in its shape or structure, all the utility model rights that falls into are wanted
The technical solution in confining spectrum is sought, is all fallen within the protection scope of the utility model.
