Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated.
With reference to figure 1 with shown in Fig. 2, an embodiment of the present utility model is a kind of device for positioning and securing of CT Guided Percutaneous Biopsies for Lung Lesions, and this device for positioning and securing comprises annular base 1, ring rotation dish 2 and guider 3, shown in composition graphs 3, the inwall of annular base 1 is provided with annular groove 11; The ring-shaped step 21 matched with annular groove 11 is set in the bottom of ring rotation dish 2 again, and the top of ring-shaped step 21 is provided with circular table 22; What is more important, circular table 22 is provided with arc 23, and arc 23 is also provided with arc track 24; Shown in composition graphs 5, aforesaid guider 3 then comprises connecting rod 31, between the center that connecting rod 31 is movably arranged on arc 23 bottom by the first bolt 32 and the second bolt 33 and arc track 24, and the head of the first bolt 32 and the second bolt 33 all needs to be provided with pilot hole 4, and the pilot hole 4 on the first bolt 32 and the second bolt 33 also needs to connect into straight line, and namely aforesaid pilot hole can be used as the inserting needle passage of CT Guided Percutaneous Biopsies for Lung Lesions; Preferred technological means is, is installed vertically on circular table 22 by aforesaid arc 23, to ensure the accuracy adjusting angle.
In the present embodiment, by the ring-shaped step 21 of ring rotation dish 2 bottom is nested in the annular groove 11 on annular base 1 inwall, ring rotation dish 2 can be rotated on the top of annular base 1, again by adjustment arc 23 on guider 3 and arc 23 bottom between angle, the i.e. angle of pilot hole 4 on adjustable first bolt 32 and the second bolt 33, and then find the needle angle of suitable pilot hole 4 angle as Transthoracic Biopsy, needle body is made to enter intralesional according to predetermined needle track, swing because of fixing shakiness after effectively preventing needle set from puncturing into tissue, avoid repeated localised puncture and carry out CT scan, reduce the probability that complication occurs.
Shown in Fig. 1, according to another embodiment of the present utility model, for ease of annular base 1 is fixed on the body surface of patient, at least two symmetrical wing plates 12 can be extended outward at the outer wall of annular base 1, by medical proof fabric, wing plate 12 is bonded, annular base 1 can be fixed on the body surface of patient, and for increasing the fixing stability of annular base 1, also wing plate 12 in the present embodiment can be set to four facing each other as shown in Figure 2.
Further, shown in composition graphs 4, be similarly the accuracy promoting guider 3 angle adjustment, preferably above-mentioned arc 23 is directly set to semicircle, and connecting rod 31 is movably arranged on after between the center of arc 23 bottom and arc track 24 by the first bolt 32 and the second bolt 33, overlap with the radius of arc 23; On the basis of aforementioned structure, also can on the extrados of arc 23 multiple angle mark groove 25, and according to the different angles of required adjustment, the different angle in interval equidistantly arranges aforesaid all angles marker groove 25, and the position of such as, in the present embodiment shown by Fig. 4 respectively on arc extrados 30,60,90,120,150 degree arranges five angle mark grooves 25.
On the other hand, inventor also finds in test, trickle precision difference between arc track 24, arc 23 and connecting rod 31, the angle adjustment of later stage pilot hole 4 and CT scan gained lung inner disease foci and skin-marker angulation all can be caused to there are differences, what therefore the structural design of this fixture was the most key is exactly a bit promote degree of accuracy, and inventor is be set to overlap in the center of circle corresponding with arc 23 for the center of circle of arc track 24 correspondence to this in the further improvement that above-described embodiment based uplink does; And directly above-mentioned annular base 1 is annular with ring rotation dish 2, and the circular table 22 on ring rotation dish 2 is overlapped with the top of annular base 1.
Shown in figure 1, this utility model preferred embodiment in actual use, owing to being provided with annular base 1, ring rotation dish 2 and guider 3, annular base 1 is fixed on patient body-surface gauge point by medical proof fabric, can according to patient body-surface gauge point rotary annular rotation disc and the angle adjusting guider after fixing.Then according to CT scan gained lung inner disease foci and skin-marker angulation, rotary annular rotation disc 2 to proper orientation adjust guider 3 to measured angle according to the angle mark groove 25 that arc 23 extrados is carved with again, and fix the first bolt 32 and the second bolt 33, upper and lower two pilot holes 4 are interconnected on same straight line, make its angle consistent with CT scan gained lung inner disease foci needle angle.Now, guider 3 is just fixed in the preoperative inserting needle position determined, upper and lower two pilot holes on same straight line 4 are biopsy needle needle angles with focus angulation, by biopsy needle according to pilot hole 4 inserting needles of the preoperative measured degree of depth from upper and lower two coincidences, needle body can enter intralesional according to predetermined needle track, prevents needle body from swinging, and then without the need to repeated localised puncture and CT scan in art, convenient operation, and reduce thus to the complication that patient brings.
