Embodiment 1

[0077] Embodiment 1: The navigation and positioning device for tongue ablation surgery of the present invention of mechanical navigation and positioning mechanism

[0078] reference Figure 1 to Figure 8 In this embodiment, the tongue ablation surgery navigation positioning device 99 includes an upper positioning plate 1, a lower positioning plate 2, a fixing bracket 3, and a positioning mechanism 4.

[0079] The upper positioning plate 1 has a geometric shape matching the shape of the tongue and the alveolar bone. The upper positioning plate 1 is provided with a connecting mechanism 11 connected to the fixing bracket 3, and the upper positioning plate 1 is close to The end is connected to the upper end 31 of the fixing bracket 3 through the connecting mechanism 11. The upper positioning plate 1 covers the tongue body 6, and the upper positioning plate 1 presses down the tongue body 6 and cooperates with the bone tissue of the lower teeth and alveolar bone to fix the tongue body on...

Embodiment 2

[0119] Embodiment 2: The navigation and positioning device for tongue ablation surgery of the present invention of the electromagnetic navigation positioning mechanism

[0120] reference Picture 9 The difference between this embodiment and Embodiment 1 is that the positioning mechanism 4 in this embodiment is an electromagnetic navigation positioning mechanism.

[0121] In this embodiment, the operation hole 41 of the positioning mechanism 4 is the operation window 23 of the lower positioning plate 2.

[0122] The positioning mechanism 4 includes a magnetic positioning element 43 and a magnetic positioning device 43-1; the magnetic positioning element 43 is located at the front end of the surgical instrument 100, and the magnetic positioning device 43-1 can be positioned at the front end of the surgical instrument The spatial position of the magnetic positioning element 43 is an electromagnetic device.

[0123] The surgical instrument 100 used in conjunction with the navigation posit...

Embodiment 3

[0127] Embodiment 3: Tongue ablation surgery navigation and positioning device of the present invention with magnetic navigation and positioning mechanism

[0128] reference Picture 10 The difference between this embodiment and Embodiment 2 lies in that, in this embodiment, the positioning mechanism 4 realizes the positioning of the surgical process through the change of the ordinary magnetic field.

[0129] The positioning mechanism 4 contains magnetic material powder or ferromagnetic material powder 43-2; the magnetic material powder or ferromagnetic material powder 43-2 is arranged in the closed cavity of the upper positioning plate 1 corresponding to the operation area . The upper end of the fixed bracket 3 is provided with a camera system 17.

[0130] Observe the degree of aggregation of the magnetic material powder or ferromagnetic material powder 43-2 to the magnetic positioning element 43 at the front end of the surgical instrument and the magnetic powder spots formed by th...

Abstract

The invention provides a tongue body ablation operation navigation positioning device, including an upper positioning plate, a lower positioning plate, a fixing support, and a positioning mechanism. The upper positioning plate has a geometrical shape matched with a tongue body and an alveolar bone. The lower positioning plate has a geometrical shape matched with the appearance of a lower jaw. Theupper end of the fixing support is connected with the upper positioning plate. The lower end of the fixing support is connected with the lower positioning plate. The tongue body is fixed by the upperpositioning plate, the lower positioning plate, and a bony structure on the lower jaw. The lower positioning plate is provided with a surgical operation window. The positioning mechanism is a navigation positioning mechanism which can guide tongue body ablation related surgical instruments to be inserted into a target region to perform an ablation operation. The positioning mechanism is provided with surgical operation holes. Surgical instruments enter a tongue body tissue through the surgical operation hole and the surgical operation window in sequence, and under navigation positioning of thepositioning mechanism, surgical operation is carried out in the target region. The tongue body ablation operation navigation positioning device makes a surgical operation process safer, more accurate, more controllable, and more convenient.

Description

Technical field [0001] The invention relates to a medical instrument used for tongue body ablation surgery, in particular to a tongue body ablation surgery navigation positioning device used in radiofrequency ablation of tongue body tissue and a matching surgical instrument. Background technique [0002] Snoring and obstructive sleep apnea syndrome (hereinafter referred to as OSAS) are common diseases that have obvious harm to human health. Among them, tongue drop caused by tongue hypertrophy is one of the main causes of snoring and OSAS . Surgical removal or ablation of the hypertrophic tongue tissue, especially the removal or ablation of the tongue tissue at the back of the tongue and the base of the tongue, which is likely to block the airway of the glossopharynx, can effectively open the glossopharyngeal airway and achieve the therapeutic factor. Snoring and OSAS caused by the fall of the tongue. All kinds of tongue body excision or tongue ablation surgery performed along t...
