Intraoperative fluoroscopy laser positioner

Abstract

The invention provides an intraoperative fluoroscopy laser positioner, which comprises a fixing belt, two laser emitters shaped like a Chinese character 'yi' and a power supply system; the fixing beltsleeves an X-ray receiving screen of an mobile fluoroscopy machine and comprises a non-elastic belt, an elastic belt and a pair of connecting pieces, the three parts are connected with each other, the closing of the fixing belt is achieved through the connection of the two connecting pieces, and the total length of the fixing belt is slightly smaller than the circumference of the X-ray receivingscreen of the mobile fluoroscopy machine; the two laser emitters are arranged on the fixing belt, and the distance between the two laser emitters is 1/4 of the circumference of the X-ray receiving screen of the mobile fluoroscopy machine, so that a laser cross point is positioned at the central point of an X-ray emitting bulb tube of the mobile fluoroscopy machine; and the power supply system is connected with the laser emitters to supply power for the laser emitters. The positioner can be directly installed on a prior fluoroscopy machine, the fluoroscopy center point of the fluoroscopy machine is formed through the laser positioner, and the fluoroscopy center of the fluoroscopy machine can be accurately positioned.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intraoperative perspective laser positioner. Background technique [0002] At present, many operations, especially orthopedic operations, need to use a mobile perspective machine to see through during the operation. In the process of reduction in orthopedic surgery, especially for unstable fractures that are difficult to reduce, unsatisfactory fracture reduction, poor internal fixation position, and length discomfort can be adjusted in time under perspective monitoring during the operation, and the correction can be observed immediately Therefore, intraoperative mobile fluoroscopy machine is widely used in orthopedic surgery. [0003] Most of the existing intraoperative mobile fluoroscopy machines do not have a positioning function. In addition, before the fluoroscopy, the surgical wound is often covered with a sterile sheet. During the fluoroscopy, it is often necess...

Problems solved by technology

[0003] Most of the existing intraoperative mobile fluoroscopy machines do not have a positioning function. In addition, before the fluoroscopy, the surgical wound is often covered with a sterile sheet. During the fluoroscopy, it is often necessary to repeatedly adjust the fluoroscopy center point in the center of the target site to obtain the ideal. Fluoroscopic imaging, while increasing the operation time, multiple invalid fluoroscopy also greatly increases the chances of patients and operators being exposed to rays
