Description
Technical field
This utility model relates to medical apparatus and instruments, especially relates to puncture needle angle guide during a kind of localised puncture.
Background technology
Minimally Interventional Therapy technology be by tiny puncture needle is thrust body cavity extraction secretions chemically examine, or do contrast examination to body cavity injection gas, contrast agent etc., or utilize special puncture needle to carry out naturopathy (such as radio frequency, microwave, radioactive prospecting instrument etc.) in vivo, or injection of medicine carries out a kind of Clinics treated in body cavity；Minimally Interventional Therapy technology is extensively applied by current medical science because of advantages such as its wound are little, treatment accurate, side effect is little, indication is wide, postoperative rehabilitation is fast, clinical efficacy is notable.When carrying out Minimally Interventional Therapy and puncturing, for improving the accuracy that deep tissue in body cavity is punctured, need to carry out puncturing the hand-manipulating of needle under the guiding of computed tomography (CT), can accurately measure out entry point, depth of needle and needle angle by CT；And when concrete puncture inserting needle, the most free-hand inserting needle of data that operator can only measure according to CT, easily cause depth of needle and needle angle that deviation occurs, especially needle angle is difficult to control；Once angle skew, it is possible to cause puncture needle away from therapy target, in some instances it may even be possible to by mistake wear the most important internal organs, blood vessel, nerve, causes related complication, and more serious being also possible to jeopardizes patient vitals；If additionally, puncture angle mistake also needs to again do CT scan, again punctured, patient's CT scan number of times is thus caused to increase, suffered amount of radiation increases, and repeated localised puncture inserting needle also extends the operating time of whole therapeutic process, brings unnecessary tissue injury and misery to patient.
Summary of the invention
This utility model purpose is to provide a kind of puncture needle angle guide.
For achieving the above object, this utility model can take following technical proposals:
Puncture needle angle guide described in the utility model, including being placed on diagnosis and treatment bed side ground height adjustment support, extends above the arc support arm being provided with angled indicateing arm quarter from described height adjustment support to described diagnosis and treatment bed；Offering the arc chute with slide block along the instruction marking of described angle on described arc support arm, the arc core of described arc chute overlaps with described arc support arm arc core, described slide block is provided with direction of illumination and points to the mobile light source of arc chute arc core；Being provided with direction of illumination fixed light source vertically downward on described arc support arm, the axis of described fixed light source coincides with the arc core vertical line of described arc support arm.
Described arc support arm is semicircular structure or quadrant shape structure.
This utility model advantage is simple in construction, easy and simple to handle, and precision is high.Fixed light source and mobile light source can be adjusted according to CT scan data, entry point when determining puncture accurately and needle angle, the most only need the hand-held puncture needle of operator to penetrate along mobile light source i.e. to complete to puncture, it is simpler, convenient to operate, precision is greatly improved, reduce the operating time, reduce maloperation, it is to avoid patient bears unnecessary tissue injury and misery.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1.
The structural representation of this utility model embodiment 2 during Fig. 2.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, puncture needle angle guide described in the utility model, including being placed on diagnosis and treatment bed 1 side ground height adjustment support 2, owing to the ground flat degree in CT Scan Room own requires the highest, therefore it is placed in ground height adjustment support 2 and ensure that and be in level；Extend above to diagnosis and treatment bed 1 from height adjustment support 2 and be provided with the arc support arm 4 carving 3 with angled indicateing arm；For making angle instruction marking 3 can accurately mark out 0 ° ~ 180 ° marking lines, arc support arm 4 is semicircular structure, it is across above diagnosis and treatment bed 1, simultaneously for ease of the arc support arm 4 of support semicircular structure, height adjustment support 2 is symmetrically arranged two, i.e. in diagnosis and treatment bed 1 arranged on left and right sides each one, it is respectively fixedly connected with the two ends of arc support arm 4.The arc chute 6 with slide block 5 is offered along angle instruction marking 3 on arc support arm 4, the arc core of arc chute 6 overlaps with arc support arm 4 arc core, the mobile light source 7(being provided with direction of illumination sensing arc chute 6 arc core on slide block 5 should move light source 7 for infrared light beam lamp or green outside line sealed beam lamp), it is ensured that when mobile light source 7 moves with slide block 5, direction of illumination points to arc chute 6 arc core all the time；Being provided with this fixed light source 8 of direction of illumination fixed light source 8(vertically downward on arc support arm 4 is infrared light beam lamp or green outside line sealed beam lamp), the axis of fixed light source 8 coincides with the arc core vertical line of arc support arm 4, ensure that the light beam that fixed light source 8 irradiates points to arc support arm 4 arc core, make the beam intersection that fixed light source 8 and mobile light source 7 irradiate on the arc core point of arc support arm 4, so that it is determined that the point of irradiation going out fixed light source 8 is point of puncture, the light beam that mobile light source 7 irradiates is needle angle during puncture.
When practical operation, operator determine entry point according to the data of CT scan, the i.e. point of irradiation of fixed light source 8, further according to the needle angle in CT scan data, slide block 5 is adjusted to this angular position together with mobile light source 7 afterwards, then height adjustment support 2 is adjusted according to the own situation of sufferer, fixed light source 8 and mobile light source 7 is made to intersect in any of sufferer body surface, to be adjusted complete after, the hand-held puncture needle of operator, by tip alignment sufferer body surface on this point, adjust puncture needle angle, the light beam making mobile light source 7 is irradiated on puncture needle backshank, will overlap with mobile light source 7 light beam by puncture needle, the most just can be along its light beam inserting needle, complete the determination to puncture needle entry point and needle angle.
Embodiment 2
For not affecting operator's puncture procedure, as shown in Figure 2, in puncture needle angle guide described in the utility model, arc support arm 4 is quadrant shape structure, angle instruction marking 3 be labeled as 0 ° ~ 90 °, by rotating diagnosis and treatment bed 1 or rotating puncture needle angle guide, it is achieved adjustment that puncture angle is 0 ° ~ 180 ° and determining；One end of arc support arm 4 is connected with being placed on diagnosis and treatment bed 1 side ground height adjustment support 2 upper end, and its other end is positioned at center position directly over diagnosis and treatment bed 1；So can accurately determine entry point and the needle angle of puncture needle, operator can stand and carry out puncture procedure in diagnosis and treatment bed 1 opposite side relative with arc support arm 4 simultaneously, facilitate operator to operate.
Actual mechanical process is same as in Example 1.
