人體的甲狀腺位於前頸部,為人體重要的內分泌器官,在甲狀腺發現異常需要手術治療時,喉返神經麻痺常是這個手術最容易發生的併發症。人體有左右兩條喉返神經,喉返神經是人體第十對腦神經-迷走神經的分支,左側的喉返神經從迷走神經的分支到胸腔、右側的喉返神經從下頸部折返回氣管,最後進入喉部,喉返神經的主要功能為控制人體喉部聲帶的活動。甲狀腺包住氣管與食道,同時也包住喉返神經,當喉返神經回氣管時與甲狀腺越來越近,到要進入喉部時幾乎與甲狀腺黏在一起,這是喉返神經在甲狀腺手術時最容易被傷到的地方。喉返神經麻痺會造成聲音沙啞或液體流入氣管等問題,嚴重影響個人生活、或工作,更嚴重者還可能發生呼吸困難。 The thyroid gland of the human body is located in the anterior neck and is an important endocrine organ of the human body. When the thyroid gland is found to require abnormal surgery, recurrent laryngeal nerve palsy is often the most common complication of this operation. The human body has two recurrent laryngeal nerves. The recurrent laryngeal nerve is the tenth branch of the human cranial nerve-vagus nerve. The left recurrent laryngeal nerve is folded from the vagus nerve branch to the thoracic cavity, and the right recurrent laryngeal nerve is folded back from the lower neck to the trachea. Finally, Entering the throat, the main function of the recurrent laryngeal nerve is to control the activity of the vocal cords of the human throat. The thyroid gland envelops the trachea and esophagus, and also encases the recurrent laryngeal nerve. When the recurrent laryngeal nerve is returned to the trachea, it is closer to the thyroid gland. When it enters the larynx, it almost sticks to the thyroid gland. This is the recurrent laryngeal nerve in the thyroid surgery. The most vulnerable place to be injured. Recurrent laryngeal nerve paralysis can cause problems such as hoarseness or fluid inflow into the trachea, which seriously affects the life or work of the individual. In more serious cases, breathing difficulties may occur.
隨著醫學的進步,一種神經偵測系統被發明出用以協助醫師定位喉返神經的位置,該神經偵測系統包含一氣管插管、一電極探頭,及一顯示儀表。該氣管插管包括一感測電極組,該氣管插管放在患者的喉部,並使該感測電極組與聲帶接觸。 With advances in medicine, a neurological detection system has been invented to assist a physician in locating the position of the recurrent laryngeal nerve.

在使用者要將該勾體1勾住該迷走神經20時,將該迷走神經20經由該開口125順著該彈性部123的弧狀導引入該容置空間124,使該迷走神經20與該電極片2接觸,該電極片2的尺寸大,與該迷走神經20接觸良好,接著使用者未施力於該自由臂12,則該彈性部123回復至使該開口端122與該基臂11保持 該固定距離,再夾住該夾持部62,使該夾持部62帶動該固定部61從該開口端122沿著該基臂11的一側至該固定端112延伸,並使該固定部61的一端自該固定端112圈住該突出部113且部分繞過該固定端112並沿著該基臂11的另一側套入該定位槽115,該定位槽115係由該基臂11側面的周緣形成內凹且呈漸縮型態,該固定部61連結該基臂11及該自由臂12時,由該定位槽115較寬的頂部導引而套入該定位槽115,並嵌卡於該定位槽115較窄的底部。本例中,該固定部61繞著該基臂11延伸的方向為一逆時鐘方向,此時,該固定部61束住該開口端122,且使該開口125縮小,該基臂11與該自由臂12部分碰觸且密合,該迷走神經20就不易從該勾體1鬆脫。 When the user wants to hook the body 1 to the vagus nerve 20, the vagus nerve 20 is introduced into the accommodating space 124 along the arc of the elastic portion 123 via the opening 125, so that the vagus nerve 20 and the electrode piece are 2 contact, the electrode sheet 2 is large in size, and is in good contact with the vagus nerve 20, and then the user does not apply force to the free arm 12, the elastic portion 123 returns to hold the open end 122 and the base arm 11 The fixing portion is further clamped to the clamping portion 62, so that the clamping portion 62 drives the fixing portion 61 to extend from the opening end 122 along one side of the base arm 11 to the fixed end 112, and the fixing portion is extended. One end of the ring 61 is looped from the fixed end 112 and partially bypasses the fixed end 112 and nested along the other side of the base arm 11 into the positioning slot 115. The positioning slot 115 is bounded by the base arm 11 The peripheral edge of the side surface is formed in a concave shape and is tapered. When the fixing portion 61 is coupled to the base arm 11 and the free arm 12, the positioning groove 115 is guided by the wide top of the positioning groove 115 and fits into the positioning groove 115, and is embedded. The card is stuck at the bottom of the positioning slot 115. In this example, the direction in which the fixing portion 61 extends around the base arm 11 is a counterclockwise direction. At this time, the fixing portion 61 bundles the opening end 122 and reduces the opening 125. The base arm 11 and the The free arm 12 partially touches and is in close contact, and the vagus nerve 20 is not easily released from the hook body 1.
需補充說明的是,該固定部61固定時延伸的方向為沿著該基臂11的周緣繞過該固定端112至該定位槽115定位,因此,該固定部61繞著該基臂11延伸的方向與該定位槽115的位置為相反,若是該基臂11相反兩側的周緣皆形成一定位槽115,則該固定部61繞著該基臂11延伸的方向就不需限制,為一順時鐘方向或該逆時鐘方向皆可實施。 It should be noted that the fixing portion 61 is fixed in a direction of being disposed along the circumference of the base arm 11 around the fixed end 112 to the positioning slot 115. Therefore, the fixing portion 61 extends around the base arm 11 . The direction of the positioning slot 115 is opposite to that of the positioning slot 115. If the positioning edge 115 is formed on the opposite sides of the base arm 11, the direction in which the fixing portion 61 extends around the base arm 11 is not limited. Both the clockwise direction and the counterclockwise direction can be implemented.
此外,若該基臂11的周緣未形成該定位槽115,在將該固定部61與該基臂11固定時,可將該固定部61部分套入該夾角114,也一樣達到將該固定部61與該基臂11固定。 In addition, if the positioning groove 115 is not formed on the periphery of the base arm 11, when the fixing portion 61 is fixed to the base arm 11, the fixing portion 61 can be partially fitted into the angle 114, and the fixing portion is also achieved. 61 is fixed to the base arm 11.
請參閱第六圖,本發明神經偵測系統之電極探頭的一第二實施例,與該第一實施例類似,不同處在於該固定部61部分連結於該突出部113,該基臂11的周緣未形成該定位槽115,使用者要使用該固定件6束住該開口125時,夾住該夾持部62,使該夾持部62帶動將該固定部61從該突出部113至該固定端112延伸,並使該固定部61的一端自該開口端122圈住該彈性部123,一樣達到使該迷走神經20不易從該勾體1鬆脫的效果。 Referring to FIG. 6 , a second embodiment of the electrode probe of the neuro-detection system of the present invention is similar to the first embodiment, except that the fixing portion 61 is partially coupled to the protruding portion 113 , and the base arm 11 is The positioning groove 115 is not formed on the periphery. When the user uses the fixing member 6 to bundle the opening 125, the clamping portion 62 is clamped, so that the clamping portion 62 drives the fixing portion 61 from the protruding portion 113 to the The fixed end 112 extends, and one end of the fixing portion 61 encloses the elastic portion 123 from the open end 122, and the effect that the vagus nerve 20 is not easily released from the hook body 1 is achieved.
再要補充說明的是,該固定件6除了如該第一實施例、該第二實施例所述的部分連結於該彈性部123或該突出部113,也可未與該彈性部123或該突出部113連結,直接將該固定件6同時自該開口端122與該固定端112套住該彈性部123及該突出部113,並使部分的該固定件6套入該夾角114或該定位槽115,一樣達到使該迷走神經20不易從該勾體1鬆脫的效果。 It should be further noted that the fixing member 6 may be connected to the elastic portion 123 or the protruding portion 113 in addition to the portion as described in the first embodiment and the second embodiment, or may not be coupled to the elastic portion 123 or the portion. The protrusions 113 are connected, and the fixing member 6 is directly sleeved from the open end 122 and the fixed end 112 to the elastic portion 123 and the protruding portion 113, and a part of the fixing member 6 is nested in the angle 114 or the positioning. The groove 115 has the same effect of making the vagus nerve 20 difficult to loosen from the hook body 1.
綜上所述,藉由該固定件6束住該開口125,使該開口125限縮,則該勾體1勾住該迷走神經20時,讓該迷走神經20不易從該勾體1鬆脫,更能藉由設置的該固定件6的尺寸來限縮該開口125的大小,則能配合該迷走神經20的粗細來調整該開口125的大小,而使該勾體1不會夾傷該迷走神經20,且該電極片2的尺寸大,與該迷走神經20接觸良好,因此,本發明神經偵測系統之電極探頭與勾住的該迷走神經20接觸良好,且不易鬆脫及夾傷該迷走神經20,解決習知使用上的困擾,故確實能達成本發明之目的。 In summary, when the fixing member 6 is bundled with the opening 125 to restrict the opening 125, when the hook body 1 hooks the vagus nerve 20, the vagus nerve 20 is not easily loosened from the hook body 1, and The size of the opening 125 can be limited by the size of the fixing member 6 provided, and the size of the opening 125 can be adjusted according to the thickness of the vagus nerve 20, so that the hook body 1 does not pinch the vagus nerve 20, The electrode sheet 2 has a large size and is in good contact with the vagus nerve 20. Therefore, the electrode probe of the neurological detection system of the present invention has good contact with the vagus nerve 20 that is hooked, and is not easy to loosen and pinch the vagus nerve 20, and the solution Knowing the troubles in use, it is indeed possible to achieve the object of the present invention.
