Limb puncture fixing device for DSA operation

Abstract

The invention discloses a limb puncture fixing device for DSA operation, which comprises an installation component and a limb support component; the mounting assembly comprises a fixed plate, a fixedseat, a rotary connecting seat and a position adjusting plate; the fixing plate is arranged at the bottom of the DSA operating bed; the two fixing seats are arranged in a mode of being opposite to each other left and right, and the two fixing seats are connected through a rotating rod and are in sliding fit with the fixing plate; the rotary connecting seat is arranged between the two fixed seats and comprises a rotary plate and a guide plate, the rotary plate is rotatably connected with the rotary rod, and the guide plate is arranged above the fixed plate and is vertically connected with the rotary plate; the position adjusting plate is in sliding fit with the guide plate; the limb support component comprises a support plate, a limb restraint piece and a limb support piece, wherein the left end of the support plate is rotatably connected with the position adjusting plate, the limb restraint piece is arranged at the right end of the support plate, and the limb support piece is arrangedat the left side of the limb restraint piece. The limb puncture fixing device for DSA operation has the effects that the position of the limb support assembly can be adjusted in multiple directions according to requirements, so that the limb support assembly can be better adapted to the body position of a patient, and the comfort degree is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a limb puncture fixation device for DSA. Background technique [0002] Digital subtraction angiography (Digital subtraction angiography), referred to as DSA, that is, through digital processing of angiography images, unnecessary tissue images are deleted, and only blood vessel images are retained. This technology is called digital subtraction technology, and its characteristics are The image is clear and the resolution is high. It provides real three-dimensional images for the observation of vascular lesions, the location measurement of vascular stenosis, diagnosis and interventional treatment, and provides the necessary conditions for various interventional treatments. [0003] Based on the above, in the prior art, when performing interventional surgery and other treatments on patients through the DSA operating table, it is usually necessary to perform interventional puncture fr...

Problems solved by technology

[0003] Based on the above, in the prior art, when performing interventional surgery and other treatments on patients through the DSA operating table, it is usually necessary to perform interventional puncture from the outside of the patient's arm, because the patient is lying on the DSA operating table, and there is no dedicated arm and palm. Fixation device, the arm and palm are easy to move due to unstable placement, which will affect the stability of interventional puncture and other operations
