M382110 五、新型說明： 【新型所屬之技術領域】 [0001] 本創作係有關一種手術刀，尤指一種電燒刀之刀頭方向 調整結構。 【先前技術】 [0002] 所謂内視鏡手術，就是將極細長内含光纖維、鏡片的内 視鏡放入體内，再利用高解像力的影像系統，將體内的 影像傳導致電視上進行觀察，由於影像系統有放大的作 用，因此電視上所呈現的影像可以達到二十倍左右；再 加上幾個0. 5公分的器械插管，就可以完成許多困難度極 向的手術。 [0003] 腹腔鏡手術最大的優點，在於其具有微侵襲性的功能， 因此大至子宮根除手術，小至結紮手術，所需的腹部傷 口都只有幾公分，所以對腹壁上腹膜的撕裂傷可以降低 到最小，再者，整個手術都密閉在一充氣的空間中進行 ，減少了内臟表面暴露在乾、熱的環境，降低了這些表 面灼熱、乾燥而受傷的機會，另外，因為手術是再放大 五-二十倍的鏡頭下進行，所以每項手術均成為最精緻、 最細腻的顯微手術，任何出血點、微血管的出血，均可 使用最小面積的燒灼予以止血。 [0004] 由於手術期間醫生對病患的内臟器管組織進行切割或止 血中，常常因為切割或止血組織的角度或方向不同，所 以在切割或止血時醫生都必須改變電燒刀刀頭的方向， 而在改變刀頭方向時，都會轉動電燒刀的握把，因此在 表單编號A0101 第4頁/共22頁 M382110 握把被轉動，也帶動握把所連結的傳輸電線跟著轉動， 一但在握把轉動次數多將導致傳輸電線本身產生捲繞， 或者傳輸電線外部絕緣彼覆體本身撓性度較大，再加上 醫生手上沾到血水無法握緊握把時，先前被轉動的傳輸 電線會使握把產生反射動作（讓握把產生自轉），而自行 改變刀頭方向，或者使電燒刀掉落，而造成内臟器官被 燒傷。 【新型内容】 [0005] 因此，本創作有鑑於傳統缺失，避免缺失從在，本創作 在電燒刀器具上增設有一電燒刀刀頭方向調整結構，在 手術期間可供醫生簡單、輕易的來調整刀頭方向，以避 免燒傷病患的内臟器官。 [0006] 為達上述之目的，本創作提供一種電燒刀之刀頭方向調 整結構，包括： [0007] 一電力組，其上具有一内套管，該内套管上具有一穿孔 ，該内套管上具有複數鰭片，該鰭片上嵌設有一電路板 ，於該電路板上配置有二彈片式開關，另於該電路板一 端組接有一固定塊，該固定塊上具有一凹陷部，又於該 固定塊末端供傳輸電線的複數條所組成的切割及止血蕊 線組穿入後與電路板及内套管底部所設的第三電極棒電 性連結，而該傳輸電線由複數條組成的保護迴路蕊線組 與該内套管底部所設的第一及第二電極棒電性連結； [0008] 一握把，係由兩半部的殼體組成，該殼體其内具有一容 置空間，該容置空間可供置放該電力組，於該容置空間 表單編號A0101 第5頁/共22頁 M382110 一端具有至少一缺口，另一端具有一擋片，該擋片上具 有一通孔，該通孔對應該内套管的穿孔；另於該通孔上 具有一入口，該入口的内壁上具有一第一凹槽及一第二 凹槽，該第一凹槽與第二凹槽之間有一凸環，該凸環上 具有一上斜面及一下斜面，又於該第二凹槽上具有間隔 式的定位口，該定位口在刀具調整好方向後，用以供固 定刀具3，避免刀具產生鬆動或鬆脫； [0009] 一刀具，係具有一桿狀的刀身，該刀身近於末端處具有 一擋塊，該擋塊上係由複數凸鰭組成，於擋塊下方具有 一接合部，以及該擋塊上具有二相對應可作動之凸鰭， 於該二相對應可作動的凸鰭下方各延伸有一卡掣片，該 卡掣片位於該接合部之間，談卡掣片底緣具有一鉤部， 該上緣具有一定位塊，另於該接合部下方的刀身上具有 一第一電極及一第二電極，在刀身末端插入於内套管時 ，該第一電極與該第一及第二電極棒接觸，該第二電極 與該第三電極棒接觸； [0010] 在刀具插入於握把内部時，該刀具的擋塊上的卡掣片將 於該入口内壁上的第一及第二凹槽與定位口之間產生卡 掣及定位動作，以達可輕易調整刀頭方向。 【實施方式】 [0011] 茲有關本創作之技術内容及詳細說明，現配合圖式說明 如下： [0012] 請參閱第一、二圖，係本創作之電燒刀結構分解及組合 示意圖。如圖所示：本創作之電燒刀之刀頭方向調整結 表單編號A0101 第6頁/共22頁 [0013] 構，包括：一電力組1、一握把2及—刀具3。 該電力組1，其上具有-内套管U，該内套管"上具有一 供刀具3插入之穿孔12。該内套管u具有複數絲片13， 該鰭片13上纽有-電路板14，於該電路板14上配置有 二彈片式開關15、15’，在該開關15、15，受力外壓擎 時以供電給刀具3，使刀具3在手術期間可進行切割或 止血動作。另，該電路板14 一端組接有一固定塊16，其 上具有一凹陷部161，在刀具3末端插入於該穿孔12後， =凹陷部m又以抵擋支樓刀具3。又，於該固定塊13末 端供傳輸電線17的複數條所組成的_及止血蕊線組171 穿入後與電路板14及内套管π底部所設的第三電極棒1〇 電性連結’而該傳輸電線17由複數條組成的保護迴路蕊 線組172與該内套管11底部所設的第一及第二電極棒18、 19電性連結。 [0014] 該握把2,係由兩半部的殼體21、21，組成，該殼體以其 内具有一容置空間22 ’該容置空間22可供置放該電力組i 於該谷置空間22—端具有至少一缺口 23 ,該缺口 23用 以固疋傳輸電線17，另一端具有一擋片24 ,該檔片24上 具有一通孔241，該通孔241對應該内套管11的穿孔^ 另，於通孔241上具有一入口 25，該入口 25的内壁上具有 一第一凹槽251及一第二凹槽252，該第一凹槽251與第 一凹槽252之間有一三角形的凸環26 ,該凸環26上具有一 上斜面261及一下斜面262。又，於該第二凹槽252上具 有間隔式的定位口27，該定位口 27在刀具3調整好方向後 ’用以供固定刀具3，避免刀具產生鬆動或鬆脫。又另， 表單編號A0101 第7頁/共22頁 M382110 於另一殼體21’上具有一按鈕28,該按扭對應該電路板 板14的開關15、15’ 。 [0015] 該刀具3，係具有一桿狀的刀身31，該刀身31近於末端處 具有一擋塊32，該擋塊32上係由複數凸鰭321組成，於擋 塊32下方具有一接合部33，以及該擋塊32上具有二相對 應可供按壓之凸鰭321，於該二相對應可供按壓的凸鰭 321下方各延伸有具彈性能力的卡掣片34，該卡掣片34位 於該接合部33之間，該卡掣片34底緣具有一凸肋狀的鉤 部35，該上緣具有一定位塊36。在刀具3插入於握把2内 部時，該刀具3的擋塊31上的卡掣片34將於該入口 25内壁 上產生卡掣及定位動作。另，於該接合部33下方的刀身 31上具有一第一電極37及一第二電極38，在刀身31末端 插入於内套管11時，該第一電極37與該第一及第二電極 棒18、19接觸，該第二電極38與該第三電極棒10接觸， 使電力組1所輸出的電力經過第三電極棒10傳至第二電極 38上，使刀身31前端的刀頭39可以進行切割或止血。當 刀身31有流離電流時，該流離電流經第一電極3 7傳輸至 該第一及第二電極棒18、19上，再由第一及第二電極棒 18、19上所電性連結的保護迴路蕊線組172傳至外部供電 裝置（圖中位示），供外部供電裝置將電源切斷。 [0016] 請參閱第三、四圖，係為第二圖在3-3位置的斷面剖視及 在4-4位置的側剖視示意圖。如圖所示：在刀具3與握把2 組接後，該擋塊31上的卡掣片34底緣的鉤部35位於該入 口 25的第一凹槽251中，而該卡掣片34上緣的定位塊36 定位於該定位口 27中，讓刀具3在握把2的入口 25上不會 表單編號A0101 第8頁/共22頁 [0017] 產生任何鬆動或鬆脫現象。 請參閱第五、六圖，係為第四圖的連續動作示意圖。如 圖所示：在手術期間若醫生要調整電燒刀的刀具的刀頭 時，醫生可以直接按壓二凸鐘32，使該卡擎片34内哺， 讓鉤部35離開第一凹槽251，再將擋塊31向外拉動，使該 鉤部35位移到第二凹槽252中’同時該定位塊36也離開定 位口 2 7，此時醫生可以轉動擋塊31，在同一時間該釣部 35也在第二凹槽252中轉動，即可調整刀具3的刀頭方向 〇 [0018] 在刀頭方向調整後，再將二凸鰭32按下，使該卡掣片34 内縮，讓鉤部35離開第二凹槽252，再將擋塊31向内推動 ’使該鉤部35位移到第一凹槽251中，同時該定位塊36也 再次固定於定位口 27，讓調整刀頭後的刀具不會鬆動或 鬆脫》 [0019] 請參閱第七' 八圖’係為第四圖的另一種連續動作示意 圖。如圖所示：在手術期間醫生謌整刀頭的另一種方式 ’疋直接將擋塊31向外拉動，使該卡掣片34的鉤部35受 凸環26的下斜面262頂擠，讓卡掣片34產生内縮。在鉤部 35滑入於第二凹槽252中’該卡掣片34本身的彈性再次讓 卡擎片34撐開，此時鉤部35將位於該第二凹槽252中，同 時疋位塊36也離該定位口 27’此時醫生可以轉動擋塊31 ’在同—時間中該鉤部35也在第二凹槽252中轉動，即可 調整刀具3的刀頭方向。 [0020] 在刀頭方向調整後，直接將擋塊31向内推動’使該卡掣 表單编號A0101 第9頁/共22頁 M382110 片34的鉤部35受凸環26的上斜面261頂擠，讓卡掣片34 產生内縮。在鉤部35由第二凹槽252滑入於第一凹槽251 中，該卡掣片34本身的彈性再次讓卡掣片34撐開，此時 鉤部35將位於該第一凹槽251中，同時定位塊36也固定 於該定位口 27，讓調整刀頭後的刀具不會在握把上產生 鬆動或鬆脫。 [0021] 上述僅為本創作之較佳實施例而已，並非用來限定本創 作實施之範圍。即凡依本創作申請專利範圍所做的均等 變化與修飾，皆為本創作專利範圍所涵蓋。 【圖式簡單說明】 [0022] 第一圖，係本創作之電燒刀結構分解示意圖。 [0023] 第二圖，係本創作之電燒刀結構組合示意圖。 [0024] 第三圖，係為第二圖在3-3位置的斷面剖視示意圖。 [0025] 第四圖，係為第二圖在4-4位置的侧剖視示意圖。 [0026] 第五、六圖，係為第四圖的連續動作示意圖。 [0027] 第七、八圖，係為第四圖的另一種連續動作示意圖。 【主要元件符號說明】 [0028] 電力組1 [0029] 内套管11 [0030] 穿孔 1 2 [0031] 鰭片 1 3 [0032] 電路板14 表單编號A0101 第10頁/共22頁 M382110M382110 V. New description: [New technical field] [0001] This creation is related to a scalpel, especially a cutter head direction adjustment structure of an electric burner. [Prior Art] [0002] The so-called endoscopic surgery is to put the endoscope of the extremely thin optical fiber and the lens into the body, and then use the image system of high resolution to transmit the image in the body to the TV. Observed, because the imaging system has a magnifying effect, the image displayed on the TV can reach about twenty times; plus a few 0.5 cm of the instrument cannula, many difficult and extreme operations can be completed. [0003] The biggest advantage of laparoscopic surgery is that it has a micro-invasive function, so as far as uterine eradication surgery, as small as ligation, the required abdominal wounds are only a few centimeters, so the laceration of the peritoneum on the abdominal wall It can be reduced to a minimum. Furthermore, the entire operation is sealed in an inflated space, reducing the exposure of the visceral surface to a dry, hot environment, reducing the chance of burning and drying these surfaces, and because surgery is It is magnified five to twenty times under the lens, so each operation becomes the most delicate and delicate microsurgery. Any bleeding point or microvascular bleeding can be stopped with a minimum area of cauterization. [0004] Because the doctor cuts or stops the visceral tissue of the patient during the operation, often because the angle or direction of the cutting or hemostasis is different, the doctor must change the head of the electric burner when cutting or stopping bleeding. Direction, and when changing the direction of the cutter head, the grip of the electric burner will be rotated. Therefore, in the form number A0101, page 4/22, the grip of the M382110 is rotated, and the transmission wire connected to the grip is also rotated. Once the number of rotations of the grip is too large, the transmission wire itself will be wound up, or the outer insulation of the transmission wire itself will be more flexible, and when the doctor's hand is unable to grip the grip with blood water, it is previously rotated. The transmission wire will cause the grip to reflex (to make the grip rotate), and change the direction of the cutter head or drop the electric knife, causing the internal organs to be burned. [New Content] [0005] Therefore, in view of the lack of tradition and avoiding the lack of the original creation, this creation adds an electric burner blade orientation adjustment structure to the electric knife tool, which is simple and easy for the doctor during the operation. To adjust the direction of the cutter head to avoid burning the internal organs of the patient.
