Machine determines the orientation of lesion and skin anchor point and the depth of puncture needle, i.e.,：With CT scanning machines first in the cross section of human body
On measure the position of lesion, selected in the level most preferably into pin position and needle angle, using inserting needle level, needle angle and
The three-dimensional conformation of depth of needle determines the exact position of lesion and lancet puncture.Although CT scanning machines being capable of whose really determination
Three-dimensional needle angle and depth of needle, but the process punctured all carries out patient after the removal of CT scan level, works as disease
When people leaves CT scanning machines, doctor can only determine a rough inserting needle direction, punctured, then according to the judgement of oneself
CT scan is carried out again to be confirmed.Since artificial factor is more, inserting needle inaccuracy is often resulted in, the accuracy for the treatment of is influenced.
It can cause accidentally to wear sometimes for repeatedly inserting needle, when serious, greatly pain and risk are brought to patient.
To solve the above problems, domestic and foreign scholars are in multiple directions such as CT scanning machines, lancing system and pricking devices
It is made that exploration.If instantaneous CT has an X-rayed scanning machine, this is a kind of high-grade spiral CT machine, passes through continuous exposure, immediate observation
To the conduct direction of puncture needle, but operator can be irradiated by a large amount of x lines, influence operator's health.And CT is scanned
When, site of puncture is still located in CT machine frames, therefore operator cannot accurately control and puncture direction.Second of trial is to adopt
With Pinpoint systems, it is made of laser positioning, reconstruction 3-D view stereoscopic localized and manipulator, operator is according to monitor
Former storage image document, steerable system manipulator, monitor, which can observe, punctures inserting needle track, improve puncture precision and
Safety coefficient.But the system cost is expensive, and cost is higher, and in piercing process, and patient posture variation punctures accuracy meeting
It changes.In addition to both the above direction, multidigit scholar also makes by oneself, has invented a variety of puncture locators, guider, but not yet
Overcome the above problem, it is difficult to be widely popularized.

Receive the instruction of startup angle detection by detection switch button 134；
Angle detection is carried out when receiving startup angle detection instruction and the angle state for the puncture needle that detection obtains is passed through into finger
Show that module indicates, includes the following steps：
Exercise data is obtained from 3-axis acceleration sensor 343, level angle is obtained from three-axis gyroscope 341, from the strong magnetic of three axis
Meter 342 obtains ground magnetic degree；
Judge whether current puncture needle has shake according to exercise data, shake when puncture needle and then indicated by LED light 131,
At this point, LED light 131 is shown in such a way that red is flashed；
When puncture needle is dithering, determined level angle and ground magnetic degree whether with reference to being matched with azimuth, then by matched knot
Fruit is indicated by LED light 131；When whether level angle and ground magnetic degree with azimuth with reference to being mismatched, LED indication
Lamp 131 is shown in red；When whether level angle and ground magnetic degree with azimuth with reference to being matched, LED light 131 is shown
For green.
Signified reference of the invention azimuth includes two angles：One angle is the scanning plane angle of CT scan；Separately
One angle, which is lesions position, to be entered to pierce angle relative to entering thorn point.Wherein, scanning plane angle is due to always vertical,
The angle can be indicated relative to magnetic direction, it is, scanning plane angle is by between magnetic direction and CT scan face
Line face angle indicates.Further, since scanning plane angle is related to the orientation that CT Scanner is put, and the usual position of CT Scanner is solid
Fixed, therefore, the orientation that scanning plane angle can be put according to CT Scanner is preset, and ensured sustained development storage is carried out by ROM312.
And it is only necessary to input above-mentioned to enter to pierce angle at the reference azimuth inputted required for actual operation.In addition, lesion position
Set relative to enter thorn point be respectively positioned on same CT scan face, therefore, it is the angle on CT scan face to enter to pierce angle.In addition, horizontal
When angle and ground magnetic degree are with reference to being carried out with azimuth compared with matching, it should allow there are error, when level angle and earth magnetism
Angle and when with reference to between azimuth in the error range of permission, for both matching, be otherwise to mismatch.
In addition it should be pointed out that the CT guiding punctures handle 100 of the present embodiment can input reference by two methods
Use azimuth.That is, there are two types of operating modes for the CT guiding punctures handle 100 of the present embodiment：The first operating mode is
It is completely independent operating mode, is inputted with reference to azimuth by inputting 133 hand push button mode of button.And second of work
Pattern is to connect the operating mode of CT control terminals.CT control terminals are the control hosts of CT Scanner.CT Scanner scans institute
The screen display that the image of generation passes through CT control terminals.Under the operating mode of connection CT control terminals, CT guiding puncture hands
Handle 100 connects CT control terminals by WiF modules, then obtains reference azimuth from CT control terminals.At this point, CT controls are eventually
End need the corresponding function module to match with CT guiding puncture handles, specifically, CT control terminals at least include for by
With reference to the module for being sent to CT guiding puncture handles with azimuth.Under such operating mode, doctor is passing through CT control terminal controls
When making and carrying out CT scan, after finding lesion, it can determine in CT control terminals and pierce a little, lesion is then measured by scribing line
Position relative to enter thorn point enter to pierce angle after, directly entering to pierce angle by this is sent to CT guiding punctures handle 100, to remove from
The process manually entered.Under such operating mode, CT control terminals and CT guiding punctures handle 100 form meaning of the invention
CT guiding puncture systems.
CT guiding punctures 100 application methods of handle of the present embodiment are as follows：Doctor presses by CT control terminals or manually
After knob formula inputs reference azimuth to CT guiding punctures handle 100, suitable types are installed on CT guiding punctures handle 100
Puncture needle 900, then by the syringe needle of puncture needle 900 be placed on patient entering thorn point after, fixed needle position is constant, adjust
Then the angle of whole CT guiding punctures handle 100 keeps 900 angle side of puncture needle until LED light 131 is shown in green
To the through lesions position of constant piercing patient body.
