Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific examples.

[0018] Such as figure 1 , figure 2 As shown, a chest puncture positioning device of the present invention includes a car body 1, a slide table 2, a lifting frame 3 and an arc frame 4. The car body 1 is a cube structure, and the side is a plane, which ensures that it will not swing when abutting on the operating bed or CT bed. The car body 1 is provided with slide rails arranged along the first direction, and the sliding platform is provided with a stepper motor and its driven rollers located in the slide rails, which can slide relative to the car body along the first direction, where the first direction Parallel to the abutting edge line between the device and the operating table, and on a horizontal plane. Please refer to image 3 As shown, a lifting frame 3 is also provided on the sliding table 2, and a guide rail is arranged in the sliding table 2 along a second direct...

Abstract

The invention discloses a chest puncture positioning device, and belongs to an apparatus in the field of medical treatment and public health. The chest puncture positioning device comprises a trolley body, a sliding table, a lifting frame and an arc-shaped frame. The lifting frame can be perpendicularly adjusted and can be horizontally adjusted relative to the sliding table and the trolley body. The arc-shaped frame is provided with a first slide groove and a camera which slides in the first slide groove and points to the circle center where the arc-shaped frame is located all the time. The arc-shaped frame is provided with a second slide groove and a measurement rod, wherein the length of the measurement rod is the same as the radius of the arc. The sliding table is provided with a display which is in communication with the camera. The chest puncture positioning device is low in cost, the circle center and the needle inlet point are determined through the multi-point measurement of the measurement rod on the basis of horizontal fine adjustment and perpendicular fine adjustment, it is ensured that angle deflection can not happen to a surgeon in the needle inlet process with the help of the camera, surgical risks are reduced, and complications are reduced.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a chest puncture positioning device. Background technique [0002] Pulmonary puncture surgery uses lung biopsy to sample lung lesions. This technique can also sample thoracic and mediastinal lesions. Usually performed under CT guidance. Although the puncture point, needle insertion angle and distance can be obtained through CT positioning, in actual operation, the direction and angle of needle insertion still depend on the physician's naked judgment. There will be deviation during the needle insertion process, so there are often needle insertion deviations, repeated scans and observations, and multiple needle insertions, resulting in increased chances of complications such as pneumothorax and bleeding, and increased the number of times patients are exposed to radiation. Especially for some small nodular lesions, lesions close to blood vessels and mediastinum, there are extre...
