Technical Field

[0001] This utility model belongs to the technical field of nerve monitors with stimulation detection function, and specifically relates to a nerve monitor with stimulation detection function. Background Technology

[0002] A neuromonitor with stimulation detection is a medical device used during surgery to identify, locate, and monitor the recurrent laryngeal nerve and vagus nerve. It is used in conjunction with a neuromonitoring endotracheal tube and mainly consists of a monitor host, a patient interface box, a patient simulator, and a silence detector. The monitor host, as the core device, has functions of electrical stimulation release, electromyography signal processing, information storage, and display. Its working principle is to release current to the nerve through stimulation electrodes, which generates nerve impulses in the motor nerve and conducts them to the muscles it innervates, causing muscle contraction and generating electromyography signals. After being received by the recording electrodes, the signals are transmitted back to the monitor for processing to form an electromyogram and prompt sounds, thereby indicating the state of nerve function. It is suitable for various surgical scenarios, such as thyroid surgery and parathyroid surgery. During surgery, it plays an important role in locating and identifying nerves, providing feedback on nerve function, assessing damage, and guiding surgical strategy formulation, which can effectively improve the safety and thoroughness of surgery.

[0003] When using a neuromonitor with stimulation detection function, the base and the outer casing are fixedly connected, which means that the display screen can only face one angle when the monitor is in use, thus limiting the flexibility of use. Utility Model Content

The groove has a gear groove inside, and a swingable column is sleeved on the inner side of the groove through the gear groove. The swingable column is fixed to the gear shaft at the lower left and right ends and is engaged in the gear groove. The inner wall of the swingable column has a threaded hole at the upper position. The lower end of the outer shell has a rotatable column at the rear left and right ends. The upper end of the rotatable column has a rotating shaft fixed at the middle position. The rotating shaft is sleeved inside the outer shell. The lower end of the rotatable column has a bolt fixed.

[0006] Preferably, a sheet metal frame is installed at the lower end of the outer casing, and the lower end of the sheet metal frame is provided with heat dissipation holes at the rear position.

[0007] Preferably, the outer casing is installed to the front frame and the sheet metal frame respectively by bolts, and a display screen is installed on the inner side of the front frame.

[0008] Preferably, multiple stainless steel springs are fixed inside the extension column at the upper and lower positions on the left and right sides, and the stainless steel springs are evenly distributed.

[0009] Preferably, the triangular buckle is installed with the extension post by a stainless steel spring, and the triangular buckle can retract into the interior position of the extension post when squeezed by external force.

[0010] Preferably, the rotatable column and the bolt column are sleeved inside the swingable column, and the rotatable column can rotate about the rotation axis as the center axis.

[0011] Preferably, the gear shaft is stretched downwards to make the bolt post fit into the threaded hole, and the rotatable post allows the bolt post to enter the internal position of the threaded hole through its rotatability.

[0012] Preferably, when the gear shaft is at a distance from the housing, the oscillating column can be adjusted in angle.

[0013] Compared with the prior art, this utility model provides a nerve monitor with stimulation detection function, which has the following beneficial effects:

[0014] 1. When adjusting this device, first pull down the front base. Pulling down the front base allows the triangular buckle to retract into the inner position of the extension column. As the triangular buckle moves from the inner position of the outer shell to the outer position, it is moved to the outer position by the elastic force of the stainless steel spring. At this time, the front base can be supported by the triangular buckle. Different triangular buckles result in different positions of the front base. After the front base is adjusted, move the rear base down to move the bolt column into the inner position of the threaded hole. Rotate the rear base so that the bottom of the rear base is in contact with the ground. The angle of the machine body is adjusted in this way, which can adapt to different working environments and increase the flexibility of use.

[0015] 2. The rear base moves downward so that the bolt post contacts the threaded hole. Rotating the rotatable post causes the bolt post to enter the internal position of the threaded hole, thus fixing the position of the rear base. At this time, the angle can be adjusted by the gear shaft. The gear shaft is engaged in the internal position of the gear groove, so that after the adjustment is completed, the rear base always remains at the adjusted angle. Attached Figure Description

A rear base 4 mounted on the left and right sides of the lower end of the housing 1, a groove 9 provided inside the rear base 4, and teeth provided inside the groove 9. The gear groove 11 and the groove 9 are connected to a swingable column 12 at the inner position of the gear groove 11. The swingable column 12 is engaged with the gear shaft 10 fixed at the lower position of the left and right ends in the gear groove 11. The inner wall of the swingable column 12 is provided with a threaded hole 14 at the upper position. The lower end of the outer shell 1 is provided with a rotatable column 15 at the rear left and right ends. The upper end of the rotatable column 15 is fixed with a rotating shaft 13 at the middle position. The rotating shaft 13 is sleeved in the inner position of the outer shell 1.
