Embodiment 1

[0036] The two sides of the guide pipe 25 are provided with an arc-shaped transfer groove 14 on the moving frame 22, and the toggle rod 24 is located inside the transfer groove 14, and the bottom of the fixed plate 1 is fixedly connected with a ring-shaped buffer layer. Binding straps are installed on both sides of the fixed plate 1 .

[0037] working principle:

[0038] When in use, the fixing plate 1 is placed on the outside of the patient’s skin where CT puncture is required, and is bound and fixed with a strap. The toggling lever 24 rotates along the transfer groove 14, so that the toggling block on the toggling lever 24 rotates thereupon, and the toggling block will move the two groups of push plates 18 positioned at the inside of the cavity 12 to a position far away from each other, and then the Under the guidance of the first limit groove, in order to ensure that the first push rod 17 can move completely thereupon, the cross section of the first limit groove adopts a T...

Abstract

The invention belongs to the field of medical apparatuses, and particularly relates to a guiding mechanism for CT puncture intervention. The guiding mechanism is provided for solving the problems thatpuncture positioning is troublesome, and puncture guiding is inconvenient and comprises a fixing plate, the fixing plate is provided with a window formed in the length direction of the adjusting plate, and an adjusting mechanism is arranged above an opening of the window and comprises a deflection plate of an arc structure; rotary shafts are fixedly connected to the two ends of the deflection plate, and the sides, away from each other, of the two rotary shafts are movably sleeved with expansion plates rotating in the circumferential direction of the rotary shafts. By means of the guiding mechanism, the positioning position of a needle head of the bottom of a puncture needle can be adjusted; meanwhile, the needle head is located above the top of a labeled position all the time when the puncture direction is adjusted, the puncture precision is improved, secondary positioning operation is avoided, and the puncture direction and the puncture depth during puncture can be adjusted; meanwhile, the puncture direction and depth are fixed, injuries of the puncture needle to a patient due to shaking during an operation are reduced, and the puncture precision and safety are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guiding mechanism for CT puncture intervention. Background technique [0002] CT interventional technology is a technology that uses CT as a guiding device for fine-needle aspiration biopsy or treatment. During CT interventional surgery, the patient first uses CT equipment to perform a preliminary scan, and the scan detects the position of the patient, and then according to the patient's According to the analysis of the patient's condition, the puncture position, puncture depth and puncture angle of the operation can be obtained. When the operation is performed according to the established operation plan, because there is no guiding mechanism or the function of the guiding mechanism is simple during the operation, the puncture depth and puncture position during the puncture The inappropriate puncture angle makes the operation accuracy low, the operation is troublesome, ...
