Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a lung nodule locator and its positioning method, so as to solve the problem that the existing puncture guide device cannot realize the precise positioning of the lesion point and the lesion point directly below the ribs of the human body. The problem of puncture, in order to achieve the precise puncture positioning of the focus point, in order to achieve the purpose of puncture the focus point directly below the ribs of the human body, to increase the convenience of puncture adjustment

Embodiment 1

[0038] A pulmonary nodule locator that incorporates Figure 1 to Figure 5 As shown, it includes a vertical fixing column 3, a lesion point positioning mechanism and an oblique needle insertion mechanism.

[0039] The vertical fixing column 3 is positioned and clamped to the head of the bed board 1 by the positioning splint 2, and the vertical fixing column 3 is a vertical circular tube in the present invention. One end of the positioning splint 2 is set as a clip, and the other end is provided with an extension plate. The vertical fixing column 3 is fixedly arranged on the extension plate. The clip can effectively clamp and locate the head of the bed board 1 to ensure the overall stability of the device.

[0040]In addition, the positioning splint 2 in the present invention can also be an I-shaped steel plate, the notch of the I-shaped steel plate is clamped to the bed board 1, and then the I-shaped steel plate and the bed board 1 are fixed by bolts.

[0041] The focus point ...

Embodiment 2

[0077] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that this embodiment changes the specific structure of the lesion point positioning mechanism and the inclined needle insertion mechanism. Figure 6 and Figure 7 shown.

[0078] In this embodiment, the lesion point positioning mechanism includes a vertical adjustment column 18 connected to the vertical fixing column 3 through the first universal joint adjustment structure 16, and the vertical adjustment can be realized by adjusting the first universal joint adjustment structure 16. The adjustment of the position of the adjustment column 18 ensures that the position of the vertical adjustment column 18 is directly above the lesion point.

[0079] The first universal joint adjustment structure 16 includes a first universal joint 161 connected to the side wall of the vertical adjustment column 18, a first connecting rod 162 connected with the first universal joint 161, and a first connectin...

Abstract

The invention discloses a pulmonary nodule locator and a locating method thereof. The pulmonary nodule locator comprises a vertical fixing column clamped to a bed board in a located mode through a locating splint, the vertical fixing column is provided with a focus point locating mechanism device capable of moving at any positions above the ribs of a human body and capable of being located above focus points in a connecting mode, and the focus point positioning mechanism is provided with an inclined needle insertion mechanism for enabling a puncture needle to obliquely penetrate the part between the ribs of the human body and capable of adjusting the needle insertion angle. The adjustment amount of a needle insertion angle adjustment structure can be calculated based on the principle of similar triangles, and because an adjusted inclined telescopic needle insertion pipeline and the focus point are always in a same straight line, it can ensure that the penetrated-in puncture needle is accurately pierced into a focus and can pierce into obliquely from the position between the two ribs of the human body.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly to a pulmonary nodule locator and a positioning method thereof. Background technique [0002] Pulmonary nodules refer to intrapulmonary nodules with a diameter of <30 mm, and it is difficult to determine their nature in the early stage. There is a certain probability of malignancy in pulmonary nodules. Early diagnosis is the key to prognosis, how to distinguish between benign and malignant is one of the difficult problems in clinical diagnosis and treatment. In recent years, with the development of new fiberoptic bronchoscopy, high-resolution CT, and thoracoscopic techniques, the development of percutaneous lung biopsy has provided help for the clinical differentiation of benign and malignant pulmonary nodules. Percutaneous lung biopsy is an effective method for the diagnosis and treatment of pulmonary nodules, but how to achieve safe, efficient and convenient p...
