Puncturing fixing bracket

Abstract

The invention relates to a puncturing fixing bracket. The puncturing fixing bracket comprises a fixing device for fixing a puncturing needle, an angle fine adjusting device for adjusting the needlingangle of the puncturing needle and a plurality of connecting feet, wherein the fixing device comprises an end cover and a cylindrical sleeve; the end cover is rotatably connected with one end of the sleeve; a V-shaped embedding groove is formed from the outer side wall of the end cover to the circle center of the end cover in an extending manner, and is used for allowing the puncturing needle to be placed; a strip V-shaped embedding groove which extends to the center line of the sleeve in the radial direction along the outer side wall of the sleeve is formed in the length direction of the sleeve; the two embedding grooves are mutually staggered through the rotating of the end cover on the sleeve to form a channel for clamping and fixing the puncturing needle; the angle fine adjusting device comprises a grasping plate and a rotating seat mounted on the grasping plate, wherein the rotating seat penetrates through the grasping plate to be fixed by the grasping plate; the rotating seat isconnected with one end away from the end cover, of the sleeve; and the side wall of the clamping plate is connected with the connecting feet, so that the bracket is fixed to the position of human bodyrequiring puncturing through the connecting feet.

Description

technical field [0001] The invention relates to a puncture fixing bracket, which is applied in CT-guided percutaneous lung puncture and belongs to the technical field of medical equipment. Background technique [0002] At present, the morbidity and mortality rate of lung cancer in my country ranks first, which has seriously endangered the health and life safety of our nationals. In addition to malignant lesions, benign lesions such as fungal infections, nodules, interstitial lung diseases, inflammatory pseudotumors, and hamartomas frequently occur in lung diseases. For lung space-occupying diseases, it is difficult to give a clear clinical treatment based on clinical manifestations and imaging examinations alone. CT-guided percutaneous lung puncture is an important diagnostic method for lung diseases. It refers to performing negative pressure aspiration or cutting biopsy on lung lesions with a puncture needle or biopsy gun outside the body with the assistance of CT scan pos...

Problems solved by technology

The invention patent with authorized notification number CN104887324B discloses a lung puncture fixing frame. The fixing frame is an inverted C-shaped frame. The fixing frame is provided with adjustment devices in three directions: up, down, left, and right, front and back. The needle is clamped on the C-shaped frame, which solves the problem of fixing the puncture tool during the lung puncture operation; however, the fixing frame is a tool for fixing the puncture needle after the puncture is completed, and it cannot be used to fix the puncture needle during the puncture. Therefore, in clinical practice, there is an urgent need for puncture-assisted fixation tools that can solve problems such as clinicians' human error, operating experience and other factors that reduce puncture accuracy and cause complications for patients.
