Problems solved by technology

However, since the nerve probe is held by the medical staff, it is easy to shift along with the operation; and in the case of the medical staff's manpower shortage, it is difficult to ensure that the recurrent laryngeal nerve is monitored in real time during the actual operation
At the same time, due to the hand-held probe, it will also affect the field of vision and operation of the surgeon, thus affecting the continuity and safety of the operation

Embodiment 1

[0033] figure 1 It is a structural schematic diagram of the nerve detection device for cervical surgery of the present invention, as figure 1 The shown nerve detection device for neck surgery includes a detection head 1 , a clamping member 2 and an extension member 3 . The clip 2 is an arc-shaped strip that can be clipped on the tracheal cartilage ring 5. One end of the clip 2 is provided with a detection head 1 for detecting the recurrent laryngeal nerve 6, and the other end of the clip 2 is provided with a prolonging clip. 2 extensions 3. Wherein, the detection head 1 is rotatably fixed on the clip 2 , and the extension piece 3 is telescopically fixed on the clip 2 .

[0034] figure 1 Both the detection head 1 and the extension piece 3 are shrunk in the clamping member 2, the end of the clamping member 2 provided with the detection head 1 is provided with a slot for accommodating the detection head 1, and the side of the clamping member 2 in contact with the tracheal cart...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the slot is a through groove connecting the inner side and the outer side, and the connecting part is a plastically bent bending part 122 .

[0043] Such as Figure 9 and Figure 10 As shown, after the slot is set as a through slot connecting the inner side and the outer side, the detection head 1 can be selectively rotated out from the outer side or the inner side of the fastener 2, which is suitable for different operating environments and patients. The connecting piece is a plastically bent bending piece 122, and the medical staff can bend the bending piece 122 according to the position between the probe 11 and the recurrent laryngeal nerve 6 during the actual operation, and the bent piece deformed after bending Due to its plasticity, 122 can maintain the bent shape, so that the probe 11 can always be in contact with the recurrent laryngeal nerve 6, and the operation is more convenient.

[0044] Wherei...

Embodiment 3

[0046] Such as Figure 11 to Figure 13 As shown, a limit mechanism is provided between the clip 2 and the extension 3 of the nerve detection device for neck surgery, and the limit mechanism is mainly used to limit the relative movement between the clip 2 and the extension 3 .

[0047] Therefore, a limit groove 72 is provided on the outer surface of the extension piece 3, and a limit button 70 is provided on the outer wall surface of the clamping member 2, and the limit tooth 71 is fixed at the bottom of the limit button 70, and the limit button 70 is carried by a limiter through a reset member such as a spring. The position tooth 71 is pressed against the outer surface of the extension piece 3. When the position limit tooth 71 is aligned with the limit groove 72, the position limit tooth 71 can automatically enter into the limit groove 72 to complete the docking, so that the clamping member 2 and the extension piece 3 are relatively tight.

[0048] In this embodiment, the mai...

Abstract

The invention discloses a neck surgery nerve detecting device which comprises a detecting head and a clamping piece. The clamping piece is in an arc strip shape and can be clamped on a trachea cartilage ring. The detecting head is rotationally fixed to one end of the clamping piece. A signal interface for connecting a signal line is formed in the clamping piece. The neck surgery nerve detecting device can be fixed to the neck of a patient and can conduct real-time monitoring on recurrent laryngeal nerves in the neck surgery process, and the problem that a nerve detecting probe needs to be heldby medical staff in the surgery process is solved.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a nerve detection device for neck surgery. Background technique [0002] The recurrent laryngeal nerve is a mixed nerve, its muscular branches innervate the laryngeal muscles except the cricothyroid muscle, and its sensory fibers distribute to the laryngeal mucosa below the glottic cleft. Among them, the right recurrent laryngeal nerve leaves the right vagus nerve in front of the first segment of the right subclavian artery, goes around behind it, and then ascends in the groove between the trachea and the esophagus. The left recurrent laryngeal nerve leaves the left vagus nerve at the anterolateral side of the aortic arch, close to the distal end of the arterial ligament, bypasses the aortic arch, and then ascends in the ipsilateral tracheoesophageal groove. [0003] The recurrent laryngeal nerve is easily injured during neck surgeries such as thyroidectomy and parathy...
