Description
Technical field
The present invention relates to a kind of medicine equipment, especially a kind of tumor puncture articles for use, specifically a kind of chest, abdominal swelling
The accurate puncture locator of knurl.
Background technology
At present, the puncture under chest, the CT guiding of abdominal cavity tumour, which is generally required, is carried out in two steps, and first, carries out CT and sweeps
Retouch, select suitable body puncture point, then, CT scan, selects needle angle again.During puncture, as soon as inserting needle segment distance, weight
Multiple scanning once, constantly corrects direction and the depth of inserting needle.This method makes patient that CT scan is repeated, and receives a large amount of
Radiation;And puncture the personal experience that success is highly dependent on doctor.Meanwhile, the puncture precision of this method is not yet
It is high.Lung tumors of the diameter below 1 centimetre, can be punctured exactly with regard to few doctors.Therefore, Chinese patent
201210521809X discloses one kind and can quickly positioned, and reduces the puncture locator of patient's raying damage, preferably solves
Inserting needle position and the problem of angle Selection, but the premise that this device is used is to need to find horizontal plane, the amount of making in patient body-surface
Angle device lies in a horizontal plane at patient's point of puncture position and could carried out, but due to personal physiological structure feature, it is difficult to need to be worn in patient
Thorn position finds plane to place protractor, simultaneously because it uses 180 degree protractor, frequently results in left and right interference, measures simultaneously
Angle device must also be with point of puncture in same section, and CT imaging difficulty is big therefore inconvenient during use, it is also difficult to
Avoid important organ.Chinese patent 201610935113X discloses a kind of locator of arm structure, and it is imaged according to CT and determined
Angle realize positioning to adjust the angle of folder needle arm, but this structure needs to adjust the space angle of needle holder repeatedly and deposit
In adjustment inconvenience, and single needle puncture can only be carried out, it is impossible to the situation of many pin punctures is needed for " radioactive prospecting instrument " etc..
Another precise positioning device is to make certain thickness puncture template, and hole of threading a needle is stamped in template, and puncture needle insertion is worn
In pin hole, then realize by adjusting the angle of clamping limb positioning, this structure can realize many pin punctures, and puncture precision compared with
It is high.But similarly, this inserting needle mode, because location-plate has larger thickness and causes the space angle of puncture needle to adjust
Difficulty, and because hole of threading a needle is vertical with template, puncture needle also can only be along the direction inserting needle vertical with template, flexibility
It is not enough.Therefore, it is necessary to be improved.
The content of the invention
The purpose of the present invention is to be directed in existing Needle localization to have operation inconvenience, the problem of space angle is difficult adjustment,
Design is a kind of easy to use, and adjustment is quick, accurate puncture locator simple in construction.
One of technical scheme is:
A kind of tumor puncture locator, it is characterized in that it includes the backing plate 1 being placed under patient's body, one side of backing plate 1 is fixedly mounted
There is vertical rod 2, the upper end of the vertical rod 2, which is connected with height and length-adjustable cross bar 3, cross bar 3, to be connected with and can be turned round around cross bar axle
Upper location-plate 4, the corner of upper location-plate 4 is respectively connected with a connecting rod 5, and the lower end of connecting rod 5 is connected with lower location-plate 6,
The puncture needle positioning hole 7 of multiple rows of confession puncture needle insertion is equipped with upper location-plate 4 and lower location-plate 6, adjacent two rows puncture needle is determined
The distance between position hole 7 matches with CT scan interval.
Described upper location-plate 4 is sleeved on cross bar 3 by axle sleeve 8, and axle sleeve 8 is realized circumferentially positioned by holding screw 9.
Described upper location-plate 4 is sleeved on cross bar 3 by damping structure, and angle of revolution is provided with upper location-plate 4
Sensor, to show the angle of upper location-plate revolution in real time.
The two ends of described puncture needle positioning hole 7 are in the shape of the letter V structure, and V-shaped angle is not less than 90 degree.
The two of technical scheme are:
A kind of tumor puncture locator, it is characterized in that it includes the backing plate 1 being placed under patient's body, one side of backing plate 1 is fixedly mounted
There is vertical rod 2, the upper end of the vertical rod 2 is connected with that be connected with height and length-adjustable cross tube 10, cross tube 10 can be around cross bar
The upper location-plate 4 of axle revolution, the bottom of cross tube 10, which is provided with sheer pole 11, sheer pole 11, is connected with lower location-plate 6, on
The puncture needle positioning hole 7 of multiple rows of confession puncture needle insertion, adjacent two rows puncture needle positioning are equipped with location-plate 4 and lower location-plate 6
The distance between hole 7 matches with CT scan interval.
Described upper location-plate 4 is sleeved on cross tube 10 by axle sleeve 8, and it is circumferential fixed that axle sleeve 8 is realized by holding screw 9
Position.
Described upper location-plate 4 is sleeved on cross tube 10 by damping structure, and angle of revolution is provided with upper location-plate 4
Sensor is spent, to show the angle of upper location-plate revolution in real time.
The two ends of described puncture needle positioning hole 7 are in the shape of the letter V structure, and V-shaped angle is not less than 90 degree.
Described lower location-plate 6 can be turned round around the axis of sheer pole 11.
Beneficial effects of the present invention:
The present invention is simple in construction, easy to use, without looking for benchmark, focus only need to be found on CT computers, and draw puncture inserting needle
Direction, the hole position that the direction intersects with upper and lower template as punctures the hole to be passed through, along the two hole inserting needles, can arrived
Up to focus.Simultaneously because the hole in template uses v-shaped structure, puncture needle can by design route, with any angle through fixed
Position hole, realizes and precisely punctures.
For special angle and the puncture direction of position, it can also be worn by a vectorial revolution of upper spacer to improve
The accuracy of thorn.
The present invention is simple in construction, and easily manufactured, cost is low, easy to adjust.
