Problems solved by technology

[0003] The present invention aims to solve the problem that in the prior art, the special NIM motor nerve monitor is used for nerve position monitoring in general surgery, especially thyroid surgery, which does not have the function of nerve anatomy separation, so that the monitoring and anatomy separation protection need to be replaced, and the operation is carried out step by step. As a result, the operation steps are increased, the operation time is prolonged, the operation safety is unfavorable, and the equipment expenditure is increased. For this reason, a stripping sub-type motor nerve monitoring probe is provided.

Embodiment 1

[0032] The stripper-type motor nerve monitoring probe has a handle 3, and a wire 5 is inserted in the handle. An open cavity 31, the bottom of the cavity is embedded with a metal sleeve 4 connected to the wire 5, and the rear end of the sleeve portion 14 of the rod head is inserted into the metal sleeve 4 to be electrically connected to the wire 5; The front end of the rod head is a flat curved arc portion 11, the front end of the flat curved arc portion is arc-shaped, and the outer wall of the rod head is except for the part of the socket and the arc top of the front end surface of the flat curved arc portion. Coated with an insulating layer, so that the part of the arc top of the front end of the flat curved portion is the exposed surface without the insulating layer; a typical one is: the length of the rod head 1 is 77mm, the diameter of the largest diameter part of the rod head is 4mm, and the flat curved The length of the arc portion 11 is 19mm, the widest part of the fla...

Embodiment 2

[0034] In this example, the peeling sub-type motor nerve monitoring probe is different from the previous example in that the length of the rod head 1 is 42 mm, the diameter of the largest diameter part of the rod head is 3.8 mm, the length of the flat curved part 11 is 15 mm, and the widest part of the flat curved part 11 Wide 3.8mm, the radius of curvature of the flat curved arc portion 11 is 19.4mm, the handle 3 is long 40mm, and the handle diameter is 5mm; the total length of the socket portion, the equal diameter portion and the taper portion is 27mm, and other features are the same as those of the previous example.

Embodiment 3

[0036]The stripping sub-type motor nerve monitoring probe in this example is different from Example 1 in that the length of the rod head 1 is 198 mm, the diameter of the largest diameter part of the rod head is 4.2 mm, the length of the flat curved part 11 is 25 mm, and the widest part of the flat curved part 11 Width 4.2mm, the radius of curvature of flat arc portion 11 arcs is 300mm, handle 3 length 198mm, handle diameter 15mm; Socket portion, isodiameter portion and taper portion total length 173mm, other characteristics are identical with example one.

Abstract

The stripping subtype nervus motorius monitoring probe, which is capable of reducing operation procedures, operation time and operation risks, comprises a handle(3), a wire is mounted through the handle(5), the front end of the handle is connected with a mental club head(1), the cup joint part(14) in the back end of the club head is connected with the wire in the handle, the front end of the club head is a flat-curve section(11), the front and of the flat and curve section is an arc, the outer side of the club head, except the cup joint part and the part of the front end of the flat-carve section, is covered with insulating layer, which leads the part of the front end of the flat-carve section to be the exposed surface of the insulating layer; the length of the club head is 40-200mm, the diameter of the biggest diameter section of the club head is 3-6mm, the length of the handle is 40-200mm, the diameter is 5-15mm. The stripping subtype nervus motorius monitoring probe is utilized to monitor the nervus motorius in the surgical operation.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a matching instrument for motor nerve monitoring during operation. Background technique [0002] Medtronic (Medtronic, Inc.) NIM motor nerve monitor is used in general surgery, especially in thyroid surgery for motor nerve monitoring. The instrument realizes intraoperative motor nerve localization and functional evaluation by monitoring nerve electromyographic signals. The needle-shaped nerve probe in the instrument is inserted into the muscle group controlled by the nerve that needs to be monitored. By continuously emitting pulse electrical signals, the motor nerve is transmitted to the receiving electrode, and the relevant data is analyzed by software to realize the positioning and function of the relevant motor nerve. Evaluate. Accurate positioning of the position and direction of movement of motor nerves during surgery helps avoid damage to motor nerves during surgery and reduces or...
