Description
Technical field
This utility model is a kind of armarium, relates in particular to a kind of human body puncture locator.
Background technology
At present, often adopt clinically the method for percutaneous puncture disease is diagnosed and treated, the outstanding advantages of this method is invasive, no matter is diagnosis or treatment, and patient's post-operative recovery is very fast, thereby more and more is applied to clinically.In carrying out piercing process, locate accurately puncture success rate is played conclusive effect.The past doctor generally by virtue of experience seeks puncture position, directly puncture needle is inserted lesion, operates so inaccurately, often needs repeatedly just can find diseased region accurately, is easy to occur the inserting needle deviation, affects therapeutic effect.Along with the development of Medical Imaging Technology, appeared at now the lower percutaneous puncture in CT guiding location.Determine that by the guiding of CT image documentation equipment point of puncture and paracentesis depth have improved accuracy and the safety of puncture greatly, but because the CT guiding is not real-time, CT Scanner provides puncture advance the numeral of the angle of puncture needle and the degree of depth after, still need operative doctor rule of thumb to judge, hand-held puncture needle operates, exist due to the position of doctor's gesture and the skew of direction, can not accurately locate and find accurately best surgical depth, need the shortcomings such as repeated localised puncture.
for the problems referred to above, people have also developed some puncture locators recently, puncture supporter etc., for example application number is that 201010127718.9 Chinese invention patent application discloses a kind of like this puncture positioning device, as shown in Figure 1, it comprises bed board 1 and the puncture falsework 2 that is positioned on this bed board 1, and be arranged on puncture template 3 on described puncture falsework 2, described puncture falsework 2 comprises the upper bracket 2A on top and the base 2B of bottom, described upper bracket 2A can move up and down and lock with respect to described base 2B, regulate the height of described puncture template 3, the base 2B of described puncture falsework 2 can slide along the length direction of described base 2B and lock, described puncture template 3 can be slided and rotate at the width of described bed board 1 along described upper bracket 2A, described puncture positioning device has improved the accuracy of puncture to a certain extent, but the puncture positioning action is complicated, can not be in the space three-dimensional direction arbitrarily to the location, it can not precise positioning in rotation direction, and can not well mate with people's body surface.
Summary of the invention
The purpose of this utility model is to provide a kind of simple to operate, puncture accurate positioning, the human body puncture locator that can locate on the three dimensions any direction.
for realizing above purpose, this utility model by the following technical solutions, the human body puncture locator, comprise four connecting rods, location-plate, locating support, four connecting rods sequentially are flexibly connected, each is flexibly connected the position and is provided with locking device, locating support is provided with a jacket casing and is located at the 4th connecting rod movable end, be rotationally connected with the 4th connecting rod, locating support one side is provided with out the fixing head of arcuate groove, location-plate one side is rotatably connected on locating support, one end twist-lock of opposite side is in the arcuate groove of the fixing head of locating support, the center of circle of arcuate groove and location-plate are rotatably connected on the side conllinear on fixed support, each rotary part is provided with locking device.
As a kind of improvement of the present utility model, be carved with bevel protractor on the fixing head on described locating support.
Further improve as of the present utility model, the end that described location-plate is locked on the fixing head of locating support is provided with angle indicator.
This utility model adopts above technical scheme, the quadric chain that adopts can be realized fixed position on human body, and fixed structure is simple, utilize simultaneously rotating locating support and the structure that is attached thereto the rotatable location-plate that connects, realized puncture location simple to operation, can be in the space three-dimensional any direction location of precisely puncturing, the puncture operating difficulty is reduced greatly, greatly alleviated the misery in patient's operation.
Description of drawings
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Fig. 1 is the structural representation of existing puncture positioning device;
Fig. 2 is human body puncture locator structural representation of the present utility model.
The specific embodiment
as shown in Figure 2, a kind of human body puncture locator of this utility model, comprise four connecting rods 101, 102, 103, 104, location-plate 105, locating support 106, four connecting rods 101, 102, 103, 104 sequentially are flexibly connected, each is flexibly connected the position and is provided with locking device, locating support 106 is provided with a sleeve 106A and is set in the 4th connecting rod 104 movable ends, be rotationally connected with the 4th connecting rod 104, locating support 106 1 sides are provided with out the fixing head 106B of arcuate groove, location-plate 105 1 sides are rotatably connected on locating support 106, one end twist-lock of opposite side is in the arcuate groove of the fixing head 106B of locating support 106, the center of circle of the arcuate groove of fixing head 106B and location-plate 105 are rotatably connected on the side conllinear on fixed support 106, each rotary part is provided with locking device.
Be carved with bevel protractor on fixing head 106B on described locating support 106.
The end that described location-plate 105 is locked on the fixing head 106B of locating support 106 is provided with angle indicator 107.
this utility model carries out work in the following manner: during use, patient lies on the CT bed, the CT image system punctures according to CT, and (this software is the body surface gradient according to the people to special-purpose software, radian, the interior pathological changes of body and surrounding tissue thereof are set up mathematical model and are worked out) optimum position of CT and diseased region is calculated, this human body puncture locator couples together with the corresponding body surface of patient's pathological changes by four connecting rods that sequentially are flexibly connected, after adjusting the position, the locking device of the moving position of lock link, rotate fixed support and location-plate, make side of location-plate and diseased region and CT on same plane, lock each rotation lock device, puncture needle is under the guiding of CT, along the side of location-plate to the diseased region hands art that punctures, thereby accomplish that easily lancet puncture position and diseased region and CT accomplish sight alignment, realized that puncture position is namely the best puncture position that CT calculates.
