As further improvement of the utility model, described inclinometer comprises transparent control board, and described control board is provided with the angle index that can be blocked by lead, and described angle index is arranged along the rotation direction of steering ball.
As further improvement of the utility model, described positioning body comprises two halfbodies of docking split, and the opposite side of each halfbody is respectively equipped with support cambered surface, forms described concave spherical surface after two support cambered surface splits.
As further improvement of the utility model, the wall of described locating hole is provided with covering sphere, and the upper end of described covering sphere concave spherical surface in smoothing junction also abuts steering ball.
The beneficial effects of the utility model are: after determining the best entry point of body surface, matrix is placed on body surface correct position, rotate steering ball and be adjusted to applicable angle according to inclinometer, under the assistance of bullport, can help operation doctor that puncture biopsy needle is guided target approach simply, fast and accurately, make biopsy or treatment more accurate, process is simpler, the misery of patient can be reduced, also alleviate the work load of operation doctor and risk of practising medicine.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is the structural representation of the first embodiment;
Fig. 2 is that the first embodiment steering ball rotates schematic diagram;
Fig. 3 is the structural representation of the second embodiment;
Fig. 4 is the decomposing schematic representation of halfbody and steering ball in the second embodiment.
Detailed description of the invention
If Fig. 1 is as the CT machine guiding puncture positioner shown in Fig. 3, comprising: matrix, steering ball 3 and inclinometer 8.
Contact body surface when matrix is for puncturing, be made up of two parts, one is base 4, and two is positioning bodies 5, offers and run through upper and lower forms in the middle part of base 4, and the edge of forms is inclined-plane; Positioning body 5 is placed in forms, and the edge of positioning body 5 is the inclined-plane with forms edge mate.Be provided with the locating hole 1 of up/down perforation at the middle part of positioning body 5, the wall of locating hole 1 is provided with concave spherical surface 2.This concave spherical surface 2 upwards, can regard the hemisphere face at the end as.
Steering ball 3 is arranged on locating hole 1, and steering ball 3 abuts concave spherical surface 2 thus steering ball 3 is supported by concave spherical surface 2 and can rotate on concave spherical surface 2.Diametrically be provided with the bullport 31 for penetrating puncture needle in steering ball 3, steering ball 3 surface is connected to the lead 6 be positioned at above locating hole 1, is provided with the pilot hole 7 penetrating puncture needle in lead 6, and this pilot hole 7 is communicated with bullport 31 and concentric.Puncture needle can from top to bottom pass below positioning body 5 through after pilot hole 7 and bullport 31.Because steering ball 3 to rotate, therefore the penetrating of puncture needle, pass direction and also can adjust thereupon.
Inclinometer 8 is arranged on base 4 removably, for measuring the angle that steering ball 3 turns over, structure and the process of its measurement are specific as follows: inclinometer 8 comprises the transparent control board 81 of one piece of vertical feet 4, control board 81 is provided with the angle index 82 that can be blocked by lead 6, and angle index 82 is arranged along the rotation direction of steering ball 3.As shown in Figure 2, when steering ball 3 rotates, lead 6 rotates thereupon and blocks the angle index 82 on control board 81, and operation doctor reads angle value accordingly, just can confirm the puncture angle of puncture needle.
The first embodiment as shown in Figure 1, positioning body 5 is the plate of monolithic, and steering ball 3 is only above-mentioned concave spherical surface 2 with the contact surface of positioning body 5.On steering ball 3 with the faying face of positioning body 5, normal saline is dripped, the location after steering ball 3 can be helped to rotate when doctor operates.
The second embodiment as shown in Figure 3 and Figure 4, positioning body 5 comprises two halfbodies 51 of docking split, and the opposite side of each halfbody 51 is respectively equipped with to support after cambered surface 21, two supports cambered surface 21 split and forms concave spherical surface 2.
In addition, the upper end of each support cambered surface 21 is smoothly connected to and covers cambered surface 91, the covering sphere 9 of the wall of locating hole 1 is formed in after two covering cambered surface 91 splits, cover sphere 9 equal with the sphere diameter of concave spherical surface 2, therefore after the split of two halfbodies 51, the wall of locating hole 1 can regard the sphere that is gone to push up, go the end as.Compared with the first embodiment, add and cover after sphere 9, the faying face also corresponding increase of steering ball 3 and locating hole 1, after instilling normal saline, both locating effects improve greatly.
The above embodiments effectively solve following problem:
1. for CT guided percutaneous needle biopsy provides angle adjustable path of navigation, make puncture change in the past with sensation, pattern by rule of thumb, make operation more accurate;
2. for begining to learn doctor, it can be made easierly to complete puncture procedure, and ensure that puncture accurately;
3., for the puncture compared with small lesion, improve puncture precision greatly, effectively can avoid the misery of such patient's repeated puncture biopsy;
4., for the pathological changes that position is special, as the pathological changes near the place such as important blood vessels, organ, can avoid damaging important blood vessels, organ etc., reduce medical-risk, strengthen the confidence of operation doctor;
5. each parts split design, can be easy to sterilization, ensures that the gnotobasis of medical apparatus ensures.
The above be this utility model preferred embodiment, it does not form the restriction to this utility model protection domain.
