Embodiment 1

[0026] Such as figure 1 As shown, a CT-guided percutaneous lung puncture guiding pre-positioning device includes flexible positioning parts 1 and connecting parts 2. There are eight flexible positioning parts 1 and three connecting parts 2. The connecting parts 2 can be made of medical adhesive tape or rope , eight flexible positioning parts 1 form a rectangular fence shape through three connecting parts 2, and the flexible positioning parts 1 can be freely bent, such as figure 2 with image 3 As shown, the flexible positioning member 1 includes a silicone hose 3 and a contrast agent 4 built in the silicone hose. The contrast agent 4 is filled in the silicone hose 3. The contrast agent 4 has a clearer image under CT scanning, and is flexible. The positioning part 1 itself has a certain weight, and the flexible positioning part 1 relies on its own gravity to fit the flexible positioning part 1 on the skin of the patient to be punctured. The direction and longitudinal direct...

Embodiment 2

[0028] Such as Figure 4 As shown, a CT-guided percutaneous lung puncture guide pre-positioning device includes flexible positioning parts 1 and connecting parts 2, ten flexible positioning parts 1, four connecting parts 2, eight flexible positioning parts 1 through three The connecting piece 2 forms a rectangular fence shape, and the flexible positioning piece 1 can be freely bent, such as Figure 5 As shown, the flexible positioning part 1 is a series structure formed by connecting several metal parts 5, and the number of metal parts 5 depends on the specific situation. Taking the flexible positioning part 1 with a length of 10 cm as an example, the number of metal parts 5 is generally between 8 to 15 is appropriate. In this embodiment, the shape of the metal parts 5 is cylindrical, and the series connection structure is that the metal parts 5 are connected to each other by means of hinges. Since the metal parts 5 can be flexibly rotated up and down after being hinged, the...

Embodiment 3

[0030] Such as Figure 4 As shown, a CT-guided percutaneous lung puncture guide pre-positioning device includes flexible positioning parts 1 and connecting parts 2, ten flexible positioning parts 1, four connecting parts 2, eight flexible positioning parts 1 through three The connecting piece 2 forms a rectangular fence shape, and the flexible positioning piece 1 can be freely bent, such as Image 6 As shown, the flexible positioning member 1 is a serial structure formed by connecting several metal parts 5 . In this embodiment, the metal piece 5 is spherical in shape, such as Figure 7 As shown, ring buckles 6 are provided at the head and tail of the metal parts 5 , and the metal parts 5 in series structure are buckled and connected to each other through the ring buckles 6 . In the same way, since the metal parts 5 can be flexibly rotated up and down, and even left and right after fastening, they can fit better on the patient's skin surface.

Abstract

The invention discloses a CT-guided percutaneous lung puncture guide pre-positioning device. The device comprises flexible positioning pieces and connecting pieces. The flexible positioning pieces form a rectangular fence through the connecting pieces and can be freely bent, and the flexible positioning pieces are attached to the skin of a patient to be subjected to puncture by their gravity. Theflexible positioning pieces can be freely bent in the transverse direction and the longitudinal direction and can be attached to the patient's skin without moving easily, and the accuracy of positioning is guranateed; there is basically no distance between the flexible positioning pieces and the patient's skin surface, after CT scanning imaging, the distance between the flexible positioning piecesand the patient's lung lesion and the puncture angle can be easily observed, there is no large error in actual puncture operation, and thus accurate positioning for puncture is achieved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a CT-guided percutaneous lung puncture guide pre-positioning device. Background technique [0002] CT-guided percutaneous lung biopsy is one of the important diagnostic methods for obtaining pathological evidence of peripheral lung masses. It aims to remove the patient's lung mass through physical methods for pathological tests to determine the cause of the patient. The usual method is to use CT scan to determine the location of the mass in cross-section, and then rely on the pre-positioning device to accurately locate the puncture point. For example: Chinese Invention Patent Announcement No. CN202437351U discloses a percutaneous lung puncture fence positioner, a plurality of rods form a rectangular fence shape through connectors, and multiple rods are arranged in parallel horizontally, and are connected into a rectangular fence shape through longitudinal connectors ,...
