[0003] The 3D printing device for assisting lung puncture in the prior art still has some deficiencies in use: the existing 3D printing device for assisting lung puncture in use mostly adopts rigid guide plates or simple positioning supports. The fixed guide plate cannot be adjusted in real time according to the body position change during the operation, while the conventional support can adjust the height, but lacks multi-degree-of-freedom precise positioning ability, and easily blocks the operation field and affects the operation observation. SUMMARY

[0004] The purpose of the present application is to provide a 3D printing device for assisting lung puncture to solve the problems raised in the background.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a 3D printing device for assisting lung puncture, comprising a fixed clamping assembly and an angle adjusting assembly, characterized in that: the fixed clamping assembly is arranged on one side of the angle adjusting assembly, and the fixed clamping assembly comprises a fixed sleeve, a fixed base is fixedly connected to the lower end of the fixed sleeve, a stretchable sliding column is slidingly connected to the end of the fixed sleeve away from the fixed base, and a clamping plate is fixedly connected to one side of the outer circle of the sliding column, and a clamping groove for guiding is formed in the inner side of the clamping plate.

[0006] As a further preferred embodiment of the present technical solution: a double-sided adhesive tape is installed on the bottom of the fixed base for fixing the fixed base on the body surface, the sliding column can be inserted into the fixed sleeve, and the shape of the clamping plate is arc-shaped.

[0007] As a further preferred embodiment of the present technical solution: the angle adjusting assembly comprises a semicircular plate, and an angle scale is arranged on the semicircular plate.

[0008] As a further preferred embodiment of the present technical solution: two groups of semicircular plates are symmetrically arranged, and a pointer is arranged between the two groups of semicircular plates, and a hinge block is hingedly connected to the lower end of the pointer.

[0009] As a further preferred of the technical solution: the hinge block is fixedly installed on one side of the bottom end of the fixed sleeve, and the end of the pointer away from the hinge block is fixedly connected with a ball socket, and the other end of the ball socket is ball-jointed with a ball head;

[0010] As a further preferred of the technical solution: the angle scale is fixedly arranged on one side of the semicircular plate, and the semicircular plate is in the shape of a fan;

[0011] As a further preferred of the technical solution: one end of the ball head is fixedly connected with a semicircular block, and the semicircular block is in the shape of a semicircular arc;

[0012] As a further preferred of the technical solution: the pointer is slidingly connected between the two groups of semicircular plates, and the semicircular block is slidingly connected in the clamping groove arranged on the inner side of the clamping plate.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] 1. In the present application, the fixed base is firmly attached to the patient's body surface by double-sided tape, providing a reliable initial positioning basis. The stretchable sliding column cooperates with the fixed sleeve, allowing the clamping plate to adjust the height. The special arc design effectively fits and stabilizes the path of the puncture needle, preventing slippage or deviation during the operation. The spherical surface connection between the ball head and the ball socket allows for smooth adjustment of the puncture angle with multiple degrees of freedom. The pointer is driven by the semicircular block, sliding along the semicircular plate and accurately pointing to the current set angle, providing immediate and intuitive angle feedback.

[0015] 2. In the present application, the detachable connection of the ball head and the ball socket, as well as the design of the semicircular plate using transparent material, greatly facilitates the disinfection of the device and the real-time observation of the lower skin marking point and the puncture needle point during the operation, further improving the convenience and accuracy of the operation.
