Description
Technical field
The utility model is related to a kind of CT Conducted Puncture positioner, belongs to medical instruments field.
Background technology
With the development of medical technology, the minimally invasive diagnosis under CT guiding and treatment use are more and more extensive, and this technology
Key is venipuncture.And the lower puncture of current CT guiding greatly how much in the case of adopt hand operation, need in art repeatedly to carry out
CT scan is verified, and the selection of puncture and the carrying out of puncture are confined in some two dimensional surface, and operating time is long, weight
Puncture rate is high again, increased the wound of patient, also increases the risk of operation.
Utility model content
The purpose of this utility model is that offer one kind is capable of three-dimensional fix and the adjustable CT of puncture angle draws
Lead lower puncture positioning device.
For reaching above-mentioned purpose, the utility model employs the following technical solutions：A kind of CT Conducted Puncture positioner, its
It is characterised by：It includes an annular base, sets a chute in the inwall ring of described annular base, is slidably connected in described chute
One slide block, described slide block is fastenedly connected with one end of an arc track, and be slidably connected in described arc track a guide sleeve,
The guiding channel being provided centrally with passing through for puncture needle of described guide sleeve；Described annular base is fastened by multiple support bars
Connect a multi-directional ball, a pin hole is provided with described multi-directional ball；Described multi-directional ball and guide sleeve are all using metal material system
Become, described annular base, slide block, arc track and support bar are all made using resin material.
Rail groove is provided with described arc track, the middle part hollow of described rail groove and both sides are symmetrically arranged with female rail,
Described guide sleeve is square cartridge structure, and its both sides is symmetrically arranged with the second slide block, and described second slide block coordinates in described female rail.
The central angle of described arc track is more than 90 °.
The beneficial effects of the utility model：The utility model can be according to the preoperative nearest puncture determining in three dimensions
Path, provides relatively-stationary puncture needle guiding channel on nearest puncture path, thus improving medical personnel in puncture procedure
When success rate, reduce the wound of patient and risk, improve and puncture efficiency.
Brief description
With reference to the accompanying drawings and examples the utility model is further illustrated；
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model；
Fig. 3 is the vertical profile structural representation of Fig. 1；
Fig. 4 is the structural representation after Fig. 2 removes arc track.
Specific embodiment
Presently in connection with accompanying drawing, the utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in figure 1, the utility model includes an annular base 1, set a chute in the inwall ring of annular base 1, sliding
Be slidably connected in groove a slide block 2, and slide block 2 is fastenedly connected with one end of an arc track 3, is slidably connected one in arc track 3
Guide sleeve 4, the guiding channel being provided centrally with passing through for puncture needle of guide sleeve 4.Annular base 1 passes through multiple support bars
5 are fastenedly connected a multi-directional ball 6, are provided with a pin hole in multi-directional ball 6.Wherein, multi-directional ball 6 and guide sleeve 4 are all using metal
Material is made, and can be imaged in CT image；Annular base 1, slide block 2, arc track 3 and support bar 5 are all using resin material
Make, there is good translucency.
Further, arc track 3 is provided with rail groove, the middle part hollow of rail groove and both sides are symmetrically arranged with recessed
Rail, guide sleeve 4 is square cartridge structure, and its both sides is symmetrically arranged with slide block 7, and slide block 7 coordinates in female rail.
Further, the central angle of arc track 3 is more than 90 °.
Use process of the present utility model is as follows：
Determine optimal inserting needle path and optimal entry point first with preoperative image in three dimensions.Then by this practicality
New Ring-like Type base 1 is fixed on patient body-surface and so that multi-directional ball 6 is overlapped with optimal entry point, then passes through to adjust arc track 3
In the position on annular base 1 and guide sleeve 4 position on arc track 3, the axis of guide sleeve 4 is made to be located at optimal
In inserting needle path.Wherein, adjusting arc track 3 behind the position on annular base 1, positioned at arc track 3 both sides
Resilient plug is put into fix arc track 3 in chute；Adjusting guide sleeve 4 behind the position on arc track 3, in place
Put into resilient plug to fix guide sleeve 4 in the rail groove of the both sides of guide sleeve 4.Afterwards it is possible in guide sleeve 4
Guiding under carry out puncture procedure, during puncture procedure puncture needle must pass through multi-directional ball 6 on pin hole.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited on specification with new technical scope it is necessary to determine its technology according to right
Property scope.
