The puncture locator that a kind of CT guides
Technical field
This utility model relates to medical field, is specifically related to the puncture locator that a kind of CT guides.
Background technology
CT guided puncture biopsy is a kind of common method of Diagnosis of Pulmonary Diseases and treatment, and making a definite diagnosis of some pulmonary lesions needs Puncture needle to be utilized is sampled biopsy to affected area, can be only achieved diagnostic purpose;At present, CT guided puncture of the prior art It is to find out the optimal aspect of puncture and inserting needle position by CT scan image, then marks into pin mark in body surface.
But, the direction entering pin leans on doctors experience and feel entirely, after puncture needle enters into certain depth, needs again CT sweep Retouch determine the position of insertion whether with direction and the position consistency of design, if it is inconsistent, direction or the weight of inserting needle need to be adjusted New inserting needle;The position and the degree of depth that puncture can not find and control accurately, and piercing process is complicated, puncture precision low, add The pain sensation of patient, and too increase the operating time, add the risk of operation;Meanwhile, if site of puncture is in pulmonary, also can Causing pneumothorax, hemorrhage grade to react, severe patient even can life-threatening.
Utility model content
The purpose of this utility model is to provide the puncture locator that a kind of CT guides, to solve the puncture that the problems referred to above are mentioned Process is complicated and punctures the problem that precision is low.
For solving above-mentioned technical problem, this utility model provides the puncture locator that a kind of CT guides, and it includes CT examination Bed and be slidably arranged in the CT examination bed side positioner for localised puncture direction Yu position, positioner is provided with one Puncture needle;Positioner includes seat stand, the support bar being arranged on seat stand and the connecting portion being set on support bar;Connecting portion One end has been rotatably connected a cursor, and cursor is provided with the clamping part for clamping puncture needle.
Further, CT examination bed includes base and the bed body connected by elevating mechanism;Bed board, bed it is provided with in bed body The side of plate is provided with one for installing the slide rail of seat stand.
Further, seat stand is provided with one for restricting seat stand first control portion of slide anteroposterior on slide rail.
Further, connecting portion is provided with one for restricting the second control portion that connecting portion moves up and down on support bar.
Further, the both sides of bed body are provided with guide rail, and bed board is arranged on guide rail.
Further, bed board is provided with one for the handle of push-and-pull bed board.
Further, the length of slide rail is less than the length of bed board.
The beneficial effects of the utility model are: the puncture locator that this CT guides includes CT examination bed and is slidably arranged in CT The positioner of examinating couch side, under the mating reaction of the CT image detected at positioner and CT examination bed, it is possible to accurately Find the optimal inserting needle direction of puncture, improve the precision punctured;And after determining the optimum position of inserting needle, only need to regulate connection Portion's upper-lower position on support bar, can realize the regulation of depth of needle, simplifies piercing process, piercing process is steady, accurate, Hurry up;Both reduce time and the risk of operation, alleviate again patient's misery in piercing process.

Wherein: 1, base;2, elevating mechanism;3, bed body;4, handle;5, bed board;6, connecting portion;7, slide rail;8, guide rail;9、 Seat stand;10, support bar;11, cursor;12, clamping part;13, puncture needle;14, the second control portion;15, the first control portion.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a kind of embodiment of this utility model rather than whole realities Execute example.Based on the embodiment in this utility model, those of ordinary skill in the art are institute under not making creative work premise The every other embodiment obtained, broadly falls into protection domain of the present utility model.
As depicted in figs. 1 and 2, the puncture locator that this CT guides includes CT examination bed and is slidably arranged in CT examination bed one The positioner of side;Wherein positioner is used for localised puncture direction and position, and positioner is provided with a puncture needle 13;? Under the mating reaction of the CT image that positioner and CT examination bed detect, it is possible to correctly find the optimal inserting needle side of puncture To, improve the precision punctured.
As in figure 2 it is shown, positioner includes seat stand 9, the support bar that is arranged on seat stand 9 10 and being set on support bar 10 Connecting portion 6;In being embodied as, connecting portion 6 can move up and down on support bar 10, controls the degree of depth of inserting needle;At connecting portion 6 It is provided with the second control portion 14, for restricting connecting portion 6 moving up and down on support bar 10, it is simple to staff is to connecting portion The operation of 6.
Be rotatably connected a cursor 11 in one end of connecting portion 6, and is provided with clamping part 12 on cursor 11;Wherein press from both sides Hold portion 12 for clamping puncture needle 13;In being embodied as, position and the direction of inserting needle can be regulated by regulation cursor 11, join Close CT image, determine entry point like clockwork.
As it is shown in figure 1, the CT examination bed of the puncture locator of this CT guiding includes the base 1 connected by elevating mechanism 2 With bed body 3, bed body 3 is provided with bed board 5;In being embodied as, the both sides of bed body 3 are provided with guide rail 8, and bed board 5 is arranged on On guide rail 8;Bed board 5 is provided with leader 4, it is achieved the push-and-pull of bed board 5;And when people lie on bed board 5, utilize puncture needle 13 right When affected area is sampled biopsy, the height of bed body 3 can be regulated by elevating mechanism 2, and then carry for inserting needle puncture and CT scan For convenient.
The side of bed board 5 is provided with a slide rail 7, is used for installing seat stand 9 so that seat stand 9 can on slide rail 7 slide anteroposterior, and The length of slide rail 7 is less than the length of bed board 5;In being embodied as, after people lies on bed board 5, mobile seat stand 9, make location fill Put and be positioned on same level line with site of puncture, then by regulation cursor 11, further determine that optimal entry point;Pass through afterwards The regulation connecting portion 6 upper-lower position on support bar 10, it is achieved the regulation of depth of needle, and then complete aspiration biopsy;Operation letter Single, accurate, piercing process is steady, accurate, fast, is effectively improved the precision of puncture, alleviates the misery of patient.
As in figure 2 it is shown, be provided with the first control portion 15 on seat stand 9, be used for restricting seat stand 9 on slide rail 7 before and after slide; Avoiding after the position in inserting needle direction and puncture target determines, seat stand 9 slides relative to human body lesions position again, makes puncture needle 13 insert The position entered is inconsistent with CT scan defined location, and need to adjust direction or the inserting needle again of inserting needle, has both added patient's Pain sensation, adds again time and the risk of operation.
In sum, the puncture locator that this CT guides efficiently solves and punctures through present in CT guided puncture biopsy Journey is complicated and punctures the problem that precision is low, and easy to operate, simplifies piercing process, reduces time and the risk of operation;With Time, it is to avoid because CT scan determines that the position of insertion is inconsistent with the direction of design and position, and need to adjust inserting needle direction or Again inserting needle, brings the phenomenon of unnecessary misery to patient.
