Description
本發明係有關於一種滑車手術刀具,特別是指用於切開滑車,而適用於治療扳機指手術之刀具。The present invention relates to a tackle surgical knife, and more particularly to a cutter for cutting a pulley and for treating a trigger finger surgery.
由於每個人於日常生活中使用到手指動作的機會相當多,例如工作、打電腦、使用掌型電器用品、傳簡訊、作家事、運動等,均會容易造成手指過度使用而產生有「扳機指」等病變,其常發生之位置約在掌骨與近端指骨之間的關節掌側處,各手指都可能發生,而發生的原因是肌腱發炎後滑車因增厚而變得狹窄或肌腱有結節狀膨出,使得肌腱在關節處的滑車內自由滑動出現阻礙,而產生疼痛,並隨病程之惡化,導致手指無法任意平順地伸直或彎曲,嚴重者則必需進行手術處理,以改善扳機指之症狀。Because everyone has a lot of opportunities to use finger movements in daily life, such as work, computer, palm-type electrical appliances, text messaging, writers, sports, etc., it is easy to cause excessive finger use and trigger The lesions often occur at the volar side of the joint between the metacarpal and the proximal phalanx. Each finger may occur, and the cause is that the stenosis becomes thicker or the tendon has nodules after the tendon is inflamed. The bulging bulge causes the tendon to slide freely in the trochlear joint at the joint, causing pain, and as the disease progresses, the finger cannot straighten or bend smoothly. In severe cases, surgery must be performed to improve the trigger finger. Symptoms.
目前常見用於治療扳機指的手術刀具有中華民國新型第M302351號「微創扳機手術刀結構」,包括一套殼、一連動刀座、一驅動件及一刀具;該套殼的前端具有一鉤形元件,該連動刀座係設置於該套殼的內部,該驅動件與該連動刀座進行作動連接,該刀具連接於該連動刀座的前端;以該鉤形元件將A1滑車勾起,然後以該驅動件驅動該連動刀座連同該刀具一同前進,達成有效定位,進而使該刀具切割A1滑車完成手術,然而: 雖然其具有可對進刀量作定位之功效,但對於切割角 度仍然無法做精確的定位,依然需輔助儀器或醫生的經驗;另外,其切割滑車時,係相同於一般微創的滑車手術刀具,僅將滑車切割開,但是當滑車過於增厚,使得肌腱與滑車之間過於狹窄,若僅將滑車切開,改善效果將不符期待,此時,仍需利用傳統手術方式,將患部皮膚切開,以對患部進行部份的切除,導致有傳統手術方式傷口過大,復原時間較久,而且容易傷害手部神經或組織之缺失。The scalpel currently used to treat the trigger finger has the "Mini-Invasive Trigger Surgical Knife Structure" of the Republic of China No. M302351, comprising a set of shells, a linkage knife seat, a driving member and a cutter; the front end of the casing has a a hook-shaped member, the interlocking knife seat is disposed inside the casing, the driving member is movably connected to the interlocking blade seat, the cutter is connected to the front end of the interlocking blade seat; and the hook member is used to hook the A1 pulley Then, the driving piece drives the interlocking knife holder to advance together with the cutter to achieve effective positioning, so that the cutter cuts the A1 pulley to complete the operation, however: Although it has the ability to position the amount of feed, but for the cutting angle Degree is still unable to do accurate positioning, still need the auxiliary instrument or doctor's experience; in addition, when cutting the pulley, it is the same as the general minimally invasive tackle surgical tool, only cut the pulley, but when the pulley is too thick, the tendon It is too narrow with the pulley. If the pulley is only cut, the improvement effect will not be expected. At this time, it is still necessary to use the traditional surgical method to cut the skin of the affected part to partially remove the affected part, resulting in excessive wounding in the traditional surgical method. , recovery time is long, and it is easy to damage the lack of nerves or tissues in the hand.
爰此,本發明之目的即在於改善前述缺失。Accordingly, it is an object of the present invention to improve the aforementioned deficiency.

綜合上述技術特徵,本發明主要功效將可於下述實施例清楚呈現。Combining the above technical features, the main effects of the present invention will be clearly shown in the following embodiments.
請參閱第一圖及第二圖所示,係為一種滑車手術刀具,其包括一主體(1)、一固定元件(2)及一刀體(3),再請配合參閱第三圖及第四圖所示,係配合使用方式說明如下:該主體(1)具有相對二端,其中一端為隔離段(11), 另外一端為握持段(12),該隔離段(11)上具有一導槽(111),並在該隔離段(11)端部彎折約為30度至50度而形成一阻擋部(112),該阻擋部(112)上則具有一透孔(113),進一步在該握持段(12)上設置二個定位穿孔(121),手術時,先在手指(A)的患部位置前端切開一可供該主體(1)之隔離段(11)伸入該手指(A)的小缺口(A1),之後將該主體(1)之隔離段(11)由該小缺口伸入手指(A)患部,使該隔離段(11)穿過肌腱(A2)與滑車(A3)之間,藉此,將肌腱(A2)與滑車(A3)隔開,使後續切除動作不會傷害肌腱(A2),同時,由手指(A)位置往手掌方向伸入至患部,不會接觸神經較多的手掌,侵入性低,將手術過程所受阻力以及手掌神經受損的可能性降至最低。Referring to the first and second figures, the utility model relates to a sliding surgical tool, which comprises a main body (1), a fixing component (2) and a cutter body (3), and then please refer to the third figure and the fourth figure. As shown in the figure, the mode of use is as follows: the main body (1) has opposite ends, one end of which is an isolated section (11). The other end is a holding section (12) having a guiding groove (111) and bending at an end of the isolation section (11) by about 30 to 50 degrees to form a blocking portion ( 112), the blocking portion (112) has a through hole (113), and further two positioning perforations (121) are disposed on the holding portion (12), and the position of the affected part of the finger (A) is firstly operated during the operation. The front end is cut into a small gap (A1) for the isolation section (11) of the main body (1) to extend into the finger (A), and then the isolation section (11) of the main body (1) is extended from the small gap into the finger (A) the affected part, passing the isolated section (11) between the tendon (A2) and the pulley (A3), thereby separating the tendon (A2) from the pulley (A3), so that the subsequent resection does not damage the tendon (A2) At the same time, the finger (A) position extends into the affected part of the palm, and does not touch the palm of the nerve. The invasiveness is low, and the resistance to the surgery and the possibility of damage to the palm nerve are minimized. .
該固定元件(2)之端部形成一圓錐段(21),當該主體(1)之隔離段(11)進入手指(A)患部後,將該固定元件(2)由該握持段(12)之二個定位穿孔(121)其中之一伸入該隔離段(11),並受該導槽(111)導引,以正確將該固定元件(2)伸入至該隔離段(11)的阻擋部(112),並使該圓錐段(21)穿過該透孔(113),使該固定元件(2)抵止於該透孔(113)周緣,藉此可使該固定元件(2)穩固的對欲切除之患部做為固定以及定位之作用。The end of the fixing element (2) forms a conical section (21). When the isolation section (11) of the main body (1) enters the affected part of the finger (A), the fixing element (2) is supported by the holding section (2) 12) One of the two positioning perforations (121) projects into the isolation section (11) and is guided by the guide groove (111) to correctly extend the fixing element (2) into the isolation section (11) a blocking portion (112), and passing the conical section (21) through the through hole (113), so that the fixing member (2) abuts against the periphery of the through hole (113), whereby the fixing member can be made (2) Stable to the affected part to be removed as a fixation and positioning.
該刀體(3)則呈長條型,其上並設置一連通二端之凹槽(31),並在其中一端形成二切割片(32),該二切割 片(32)形成相同該阻擋部(112)之彎折角度,當該固定元件(2)伸入該手指(A)患部,並對欲切除之患部做固定以及定位之後,則將該刀體(3)由該握持段(12)另一個定位穿孔(121)伸入至該隔離段(11)之阻擋部(112),使該二切割片(32)受該阻擋部(112)阻擋而貼抵該阻擋部(112),並使該固定元件(2)受該凹槽(31)包覆,該刀體(3)則藉此受該固定元件(2)導引,正確伸入至該隔離段(11)的阻擋部(112)。The cutter body (3) is of a long strip shape, and a groove (31) communicating with the two ends is disposed thereon, and two cutting pieces (32) are formed at one end thereof, and the two cuttings are formed. The sheet (32) forms the same bending angle of the blocking portion (112). When the fixing member (2) protrudes into the affected part of the finger (A) and fixes and positions the affected part to be removed, the blade body is (3) the other positioning perforation (121) of the holding section (12) extends into the blocking portion (112) of the isolation section (11), so that the two cutting pieces (32) are blocked by the blocking portion (112) And the fixing portion (2) is covered by the recess (31), and the cutter body (3) is guided by the fixing member (2) to correctly extend into the To the blocking portion (112) of the isolation section (11).
請參閱第四圖及第五圖所示,最後,將該主體(1)連同該固定元件(2)及刀體(3)一同緩慢由該手指(A)抽取出,此時,該刀體(3)之二切割片(32)會將該滑車(A3)所欲切除部分切除,而一併由該手指(A)內取出,方便再作病理上的切片觀察。Referring to the fourth and fifth figures, finally, the main body (1) is slowly extracted from the finger (A) together with the fixing member (2) and the body (3). At this time, the body is (3) The second cutting piece (32) will cut off the part to be cut off by the pulley (A3), and is taken out from the finger (A) for convenient pathological observation.
