Problems solved by technology

[0004] However, it is difficult to control the specific position during the inspection process. The movement process of the stent in the prior art is too rigid and will damage normal cells. In many cases, medical personnel still use manual control to control the position of the puncture needle. However, it is difficult to accurately determine the location of the lesion through manual control

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as Figure 1-8Shown is a specific embodiment of the automatic puncture needle positioning device of the present invention. This embodiment includes a puncture needle positioning frame 1 and a positioning frame adjustment mechanism 2. The puncture needle positioning frame 1 includes a bottom frame 11, a middle frame 12 and an upper frame 13. A sliding frame 14 is arranged at the bottom of the bottom frame 11. The bottom frame 11 and the sliding The frame 14 cooperates to clamp the puncture needle positioning frame 1 on the side of the CT machine. The middle frame 12 is arranged on the bottom frame 11 in a translational manner. A ring is movably arranged in the middle frame 12, and a fixed frame 15 for inserting a puncture needle is rotatably arranged on the upper frame 13; the positioning frame adjustment mechanism 2 includes a rot...

Abstract

The invention discloses an automatic puncture needle positioner comprising a puncture needle locating rack and a locating rack adjusting mechanism; the locating rack adjusting mechanism comprises a feeding and discharging mechanism, an angle adjusting mechanism, a radian adjusting mechanism and a horizontal position adjusting mechanism arranged in order on a rotary plate periphery; the rotary plate rotates to enable the feeding and discharging mechanism, the angle adjusting mechanism, the radian adjusting mechanism and the horizontal position adjusting mechanism to finish puncture needle feeding, angle adjusting, radian adjusting and horizontal position adjusting steps in order on the puncture needle locating rack; by using a CT scanned image, the locating rack adjusting mechanism can accurately adjust the puncture needle locating rack, thus allowing the puncture needle to reach the correct position, and simplifying medical personnel work; the automatic puncture needle positioner is higher in accuracy, and the medical personnel can directly puncture according to the puncture needle position.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a fully automatic puncture needle positioning device for a CT machine. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose is to draw blood tests, blood transfusion, infusion and catheterization for angiography. [0003] The puncture needle is a common tool used in the puncture process, especially in some inspection items, which need to be checked by the puncture needle, such as the position of the tumor. In the prior art, the Chinese patent with the application number CN201420366671.5 discloses a puncture device based on CT machine images. The main arm of the main arm is also provided with a rotating stretching frame, one en...
