Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] Such as figure 1 , figure 2 , image 3 and Figure 4 The shown positioning device for shoulder arthroscopy includes a positioning rod 1, an arc-shaped support arm 2 and a guiding sleeve 3. The two ends of the positioning rod 1 are respectively provided with a hemispherical rotor 4 and a probe 5. The hemispherical The rotor 4 is rotationally connected with one end of the arc-shaped support arm 2, and the arc-shaped support arm 2 is provided with a positioning screw hole 6. The positioning screw hole 6 is aligned with the hemispherical rotor 4, and a locking screw is provided in the positioning screw hole 6. 7. The top of the probe 5 coincides with the axis of the arc-shaped support arm 2. There is a chute 8 inside the arc-shaped support arm 2. The guide sleeve 3 pass...

Abstract

The invention relates to a shoulder arthroscopic surgery positioning device and a using method thereof. The shoulder arthroscopic surgery positioning device comprises a positioning rod, an arc-shapedsupporting arm and a guide sleeve, wherein a hemispherical rotating head and a probe are arranged at the two ends of the positioning rod respectively; the hemispherical rotating head is rotationally connected with one end of the arc-shaped supporting arm; a positioning screw hole is formed in the arc-shaped supporting arm; the positioning screw hole is aligned with the semispherical rotating head;a locking screw is arranged in the positioning screw hole; the top end of the probe coincides with the axis of the arc-shaped supporting arm; a sliding groove is formed in the arc-shaped supporting arm; and the guide sleeve penetrates through the sliding groove, and the axis of the guide sleeve is aligned with the top end of the probe. The positioning device is used for positioning a working channel during the shoulder arthroscopic surgery, the operation angle in the three-dimensional space can be rapidly adjusted, an operator is prevented from reinstalling the positioner after the working channel deviates, the surgery time is effectively shortened, and the complication risk is reduced.

Description

Technical field: [0001] The invention relates to the technical field of arthroscopic surgery equipment, in particular to a positioning device for shoulder arthroscopic surgery and a method for using the same. Background technique: [0002] Arthroscopy is a common method for the diagnosis and treatment of joint surgery diseases in clinic. In the process of arthroscopic surgery, the usual procedure is to initially locate the lesion through imaging or a relatively complete physical examination, and then try to insert the working channel. The working channel is the basis of all arthroscopic operations. In arthroscopic surgery, all operations in the joint cavity are performed by using various arthroscopic special instruments to be inserted into the joint cavity through the working channel, and the operation is completed in the joint cavity, and then the entire operation is completed. The working channel is mainly composed of a hollow tubular structure. At the beginning of the op...
