A limb puncture fixation device for dsa operation

Abstract

The invention discloses a limb puncture fixing device for DSA operation, which includes a mounting assembly and a limb supporting assembly; the mounting assembly includes a fixing plate, a fixing seat, a rotating connection seat and a position adjustment plate; the fixing plate is installed on the bottom of the DSA operating bed; There are two fixed seats, which are arranged opposite to each other. The two fixed seats are connected by a rotating rod and slide with the fixed plate; the rotating connecting seat is arranged between the two fixed seats, including a rotating plate and a guide plate. Connection, the guide plate is set above the fixed plate, and is vertically connected with the rotating plate; the position adjustment plate is slidingly matched with the guide plate; the limb support component includes the support plate, the limb restraint and the limb support piece, the left end of the support plate and the position adjustment plate Rotation connection, the right end is equipped with a limb restraining part, and the limb holding part is arranged on the left side of the limb restraining part. Effect: The position of the limb support component can be adjusted in multiple directions according to needs, so that it can better adapt to the patient's position and improve comfort.

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
