Problems solved by technology

[0002] The existing craniocerebral puncture auxiliary equipment is mainly divided into head-mounted head frame and C-shaped head frame. Hematoma positioning can be corrected, and at the same time, it is impossible to evaluate the residual hematoma in real time; in addition, it takes extra time to locate before surgery, which increases the risk of preoperative preparation for patients, and is not suitable for emergency patients

Abstract

The invention discloses a craniocerebral puncture auxiliary device for DSA. The device comprises a head plate, a movable fixator and a puncture auxiliary frame, the head plate used for positioning hematoma in an operation is placed below the head of a patient, and the movable fixator is fixed to a cross section position corresponding to the hematoma through a rotary knob after moving in place along one side of the head plate; the puncture auxiliary frame installed on the movable fixator comprises a first angle adjuster, a second angle adjuster and a guide rail. The first angle adjuster is adjusted to enable the second angle adjuster to be tightly attached to the scalp, then the angle of the guide rail is adjusted according to the intraoperative CT measurement angle, the hematoma center, the first angle adjuster and the tail end of the guide rail are made to be straight, and a drainage tube penetrates into the guide rail for auxiliary puncture. According to the craniocerebral puncture auxiliary device for the DSA, craniocerebral hematoma positioning and puncture auxiliary on the DSA can be completed, positioning can be completed on the DSA, and the hematoma condition can be reviewedin real time in the operation; and the guide rail can guarantee puncture stability and reduce puncture difficulty.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a craniocerebral puncture auxiliary device for DSA. Background technique [0002] The existing craniocerebral puncture auxiliary equipment is mainly divided into head-mounted head frame and C-shaped head frame. Hematoma positioning is corrected, and at the same time, it is impossible to evaluate the residual hematoma in real time; in addition, it takes extra time to locate before surgery, which increases the risk of preoperative preparation for patients, and is not suitable for emergency patients. Contents of the invention [0003] The purpose of the present invention is to provide a DSA craniocerebral puncture auxiliary device to solve the above-mentioned problems in the prior art. The positioning is completed on the DSA of the room, and the hematoma can be rechecked in real time during the operation. [0004] In order to achieve the above object, the present inven...
