Description

TARIFNAME ENDOSKOPIK DOKU KESME VE BATlN DISINA ALMA CIHAZI Bulusun Ilgili Oldugu Teknik Alan Bulus, laparoskopik cerrahide batin disina alinmak istenen ve boyut olarak operasyonun yapildigi kesilerden daha büyük olan dokularin/kitlelerin yine bu kesilerden parçalara ayrilip çikarilmasini saglayan endoskopik doku kesme ve batin disina alma Cihazi ile ilgilidir. Bulusla Ilgili Teknigin Bilinen Durumu (Önceki Teknik) Laparoskopik ameliyatlar 0,5 cm ile 1 cm arasinda degisen genisliklerdeki kesilerden gerçeklestirilmektedir. Operasyon sonrasinda, bu kesilere göre çok daha büyük kitlelerin batin disina alinmasi gerekmektedir. Kitleleri batin disina alma islemi zor ve zaman alan bir süreç olup, çogu zaman operasyonun kendisinden uzun sürmekte ve cerrahlari açik ameliyat yapmaya mecbur birakmaktadir. Bu yüzden hastalar kapali ameliyatin konforundan mahrum olmakta ve enfeksiyon riski, agri, is ve sosyal hayattan uzun süre uzak kalma gibi dezavantajlar yasamaktadirlar. Bulus, laparoskopik cerrahide batin disina alinmak istenen ve boyut olarak operasyonun yapildigi kesilerden daha büyük olan dokularin/kitlelerin yine bu kesilerden parçalara ayrilip çikarilmasini saglamaktadir. Güncel olarak laparoskopik cerrahide kitlelerin batin disina alinmasi; - Bisturi ile parçalara ayrilmasi, - Dokunun/kitlenin rotasyon hareketliyle kesilerek batin disina alinmasina yarayan morselatör adi verilen elektrikli cihazlarin kullanilmasi, Teknigin bilinen durumunda Bisturi ile büyük dokulari/kitleleri 1,5-20m genisligindeki cerrahin hareket alanini sinirlayici deliklerden/kesilerden parçalamaya çalismak oldukça zahmetli, yorucu, zaman alici ve hasta sagligi açisindan da riskli islemlerdir. Bu süreç ameliyatin süresini 60 ile 90 dakika arasinda uzatabilmektedir. Ayrica çevre dokularin yaralanma veya zedelenme riski de bahsi geçen islemler nedeniyle yüksektir. Morselatör parçalayici cihazlarinin kullaniminda ise çalisma prensibindeki dönme hareketi yüzünden çikarilmaya çalisilan dokunun/kitlenin küçük parçalar halinde batin içine yayilmasi/saçilmasi riski bulunmaktadir. Morselatör cihazinin kullanildigi operasyonlarda, eger çikarilan doku malign (kanser) Özellikte ise hasta tüm batina yayilan metastaz riskiyle karsi karsiya kalmaktadir. Yasanan aci tecrübeler nedeniyle bu cihazin kullanimi Amerika Birlesik Devletleri°nde yasaklanmis ve Avrupa Birligi ülkelerinde ise steril torbalar içinde kullanilmasi sarti getirilmistir. Fakat bu torbalarin kullanimi dahi batin içine dokunun yayilmasini tam olarak önleyememektedir. Operasyon sonunda kitleyi batin disina almanin bir baska yolu da batma yapilacak büyük bir kesidir. Bu kesi laparoskopik cerrahinin tüm avantajlarini ortadan kaldirinakta, hastanin agrisini arttirmakta ve hastanede kalis süresini uzatmakta, operasyon maliyetini yükseltmekte, enfeksiyon riski olusturmakta ve dolayisiyla hastanin isine/sosyal hayatina dönüsünü geciktirrnektedir. Bulusun Kisa Açiklamasi ve Amaçlari Bulus ile laparoskopik operasyon sonrasinda batin disina alinacak kitle histerektomi (rahim alinmasi) ameliyatinda ek bir batin kesisi yapilmaksizin; myomektomi veya adneksiyel kitle ameliyatlarinda ise vagen tepesine yapilacak 3 cm"lik kesiden kolaylikla parçalanarak çikarilabilecektir. Bulus; üstten bakildiginda (Sekil 2) üçgen seklinde olan ve kapandiginda kesici yüzleri birbirine temas eden iki adet hazneli kisim (Sekil 4) ve bu kesici haznelere bagli tutucu saplardan olusmaktadir. Bulusun iki kesici agzi/haznesi, bulus kapali konumda iken, 3cm"lik bir kesiden batin içine girebilecek sekilde tasarlanmistir. Bu agizlar batin içine girdiginde tutucu saplar yardimiyla açilir, haznenin hacmi kadar doku/kitle kesilir ve bu kitle bulus kapali konumda tutularak batin disina dogrudan çikarilabilir. Doku/kitle tekrarlayan hareketlerle hizli ve güvenli bir sekilde batin disina alinabilir. Büyük boyutlu dokular/kitleler, bulusun sagladigi avantaj ile maksimum 3cm,lik kesiden batin disina alinabilecegi için hastalar büyük bir kesinin olasi risklerinden korunmus olunur. Bulus, dokuyu/kitleyi dogrudan kestigi (morselatör cihazi gibi rotasyon hareketi yapmadigi) ve kestigi parçayi kendi haznesinde tutacak sekilde tasarlandigi için dokunun/kitlenin batin içine yayilma riski yoktur. Bulusun; cerrahi operasyonlarda kullanilabilecek, dezenfekte edilebilecek ve insan vücuduna uyumlu olacak sekilde paslanmaz çelik malzemeden üretilmesi planlanmaktadir. Bulusun kapali olarak yapilacak histerektomi ve myomektomi ameliyatlarinda kullanilmasi öngörülmektedir. OECD verilerine göre 2017 yilindaki histerektomi sayilari Almanya için yükselmistir. Türkiye için ise son veri tarihi 2012 olmakla birlikte histerektomi sayisi .915°dir (https://stats.oecd.org/index.aspx?queryid:30l 67). Amerika Birlesik Devletleri°nde ise en sik yapilan operasyon histerektomidir. Günümüzde hastalarin islerine en kisa sürede is yasamlarina dönmek istemeleri, açik cerrahinin daha maliyetli ve riskli olmasi cerrahlari minimal invaziv cerrahiye dogru yönlendirmektedir. Fakat bu konuda da dokularin batin disina alinmasi problem yaratmaktadir. 2014 yilinda FDA tarafindan power morselasyonun yasaklanmasinin ardindan Birlesik Devletlerade yapilan açik ameliyatlara bagli komplikasyonlarin sikliginda artis yasanmis, kan transfüzyonlarinin sayisi artmistir. Bunun üzerine ACOG büyük uteruslar ve myomlar için açik cerrahiyi veya steril torba içinde vaginal morselasyonu öneri olarak sunmustur. Bu öneride ise komsu organ yaralanmalarina dikkat edilmesi gerektigi belirtilmektedir (ACOG COMMITTEE OPINION Number 770). Teknigin sikistigi bu noktada bulus yeni, benzersiz ve pratik kullanim özellikleriyle çok sik tercih edilecek bir cerrahi alet olmaya güçlü bir adaydir. Histerektomi sayilarina yapilacak myomektomi sayilari da eklenirse ülkemizde, Avrupa Birligi'nde ve Birlesik Devletler'de yillik olarak çok sayida talep görecegi ortadadir. Yine OECD verilerine göre 2020 yilinda Türkiye°de gerçeklesecek histerektomi ve myomektomi sayisinin yaklasik olarak 15.000 adet olmasi beklenmektedir. Bunun %30"unun kapali yöntemlerle yapilacagi tahmin edilmektedir. Istatistiki verilere göre bulus, 2020 yilinda hazir olmasi durumunda yillik 4500 jinekolojik operasyonda kullanilabilecektir. Kapali ameliyatlar sadece jinekolojinin ilgilendigi bir alan degildir. Artik tüm cerrahlar operasyonlari minimal invaziv yöntemle yapmak istemektedir. Genel cerrahide safra kesesi, kolon ve özefagus operasyonlari; ürolojide prostat ve böbrek alma ameliyatlari ortopedide artroskopik islemler gittikçe artan oranda laparoskopik olarak yapilmaktadir. Bu artis dokularin çikarilmasinda zorluklari da beraberinde getirmektedir. Bulus, yapilan tüm batin ameliyatlarindan sonra büyük kitleleri küçük kesilerden güvenli bir sekilde çikarmak için kullanilabilir. Bulusu Açiklayan Sekillerin Tanimlari Bu bulus ile gelistirilen endoskopik doku kesme ve batin disina alma cihazinin daha iyi açiklanabilmesi için kullanilan sekiller ve ilgili açiklamalar asagidadir.

Laparoskopik cerrahi sonrasinda büyük bir kitlenin batin disina alinmasi; kitle büyüklügünde ek bir kesi yaparak, morselatör cihazi kullanarak, histerektomi ameliyatlarinda vagen tepesi, myomektomi ve adneksiyel kitle ameliyatlarinda vagen tepesine yapilan ek bir kesiden bisturi ile kitlenin parçalara ayrilmasi ile mümkündür. Minimal invaziv cerrahide hedeflenen laparoskopik yaklasimlarda büyük bir kesi yapmanin yeri yoktur. Morselatör kullanimi ise çikarilmak istenen dokularin batin içine yayilmasina neden oldugu için birçok cerrah tarafindan terkedilmistir. Büyük kitlelerin batin disina alinmasi günümüzde en çok mevcut kesilerden bisturi ile parçalara ayirilarak yapilmaktadir. Bu islem hem zor hem zaman alici hem de çevre dokularda yaralanma riski olusturan bir yöntemdir. Mevcut yöntemler yerine söz konusu bulusun kullanilmasi güvenli, hizli ve kolay bir çözüm önerisidir. Bulus agiz (l), sap (2) ve tutamaç (3) bölümlerinden olusmaktadir. Agiz kismi tabanlari (keskin yüzeyleri) birbirine bakan ve üstten bakildiginda üçgen seklinde hazneli üst kesici (1.1) ve hazneli alt kesici (1.2) olmak üzere iki adet hazneli kesiciden olusmaktadir. Kullanim kolayliginin yani sira, bu tasarim sayesinde bulus operasyon sirasinda kullanilan veya vagen tepsine açilan yaklasik 3cm`lik bir kesiden batin içine girebilecek, batin disina alinmak istenen kitleyi kavrayip kesecek ve kestigi parçayi kendi haznesinde (1.1, 1.2) muhafaza edecektir. Böylece çikarilmak istenen kitle diger batin bölgelerine ve kesi hattina temas etmeden çikarilabilecektir. Ayrica agiz (1) kisminin disindaki yuvarlak tasarim sayesinde çevre dokulara zarar vermemektedir. Kesip batin disina alma isleminin seri tekrari ile büyük kitleler batin disina hizli, güvenli ve diger batin kisimlarina ve kesi yerine temassiz bir biçimde alinabilecektir. Bulus birbirine es iki parçadan olusmaktadir. Her parça bir agiz (1), bir sap (2) ve bir tutamaç (3) kismina sahiptir. Bulusun agiz (1) kismi üstten bakildiginda üçgen seklindedir ve taban kisminda kesici yüzey bulunmaktadir. Hazneli üst kesicinin (1.1) ve hazneli alt kesicinin (1.2) genisligi, yüksekligi ve derinligi sirasiyla; 25, 11 ve 25 mm`dir. Hazneli üst kesici (1.1) ile hazneli alt kesicinin (1.2) birbirlerine bakan kisimlari (cihaz kapali konumdayken temas eden yüzeyleri) keskin özellikte olup, myom veya uterusu kesebilecek sekilde tasarlanmistir.

TR TR TR DESCRIPTION ENDOSCOPIC TISSUE CUTTING AND EXTRACLAIMING DEVICE Technical Field to which the Invention Relates: The invention is based on an endoscopic tissue cutting and extraabdominal device that enables the tissues/masses that are desired to be removed from the abdomen in laparoscopic surgery and that are larger in size than the incisions where the operation is performed, to be dissected and removed from these incisions. It is relevant. Known State of the Technique Related to the Invention (Prior Art) Laparoscopic surgeries are performed through incisions with widths varying between 0.5 cm and 1 cm. After the operation, masses much larger than these incisions must be removed from the abdomen. The process of removing the masses from the abdomen is a difficult and time-consuming process, and often takes longer than the operation itself, forcing surgeons to perform open surgery. Therefore, patients are deprived of the comfort of closed surgery and experience disadvantages such as risk of infection, pain, and being away from work and social life for a long time. The invention enables the tissues/masses to be removed from the abdomen in laparoscopic surgery, which are larger in size than the incisions where the operation is performed, to be dissected and removed through these incisions. Currently, in laparoscopic surgery, the removal of masses from the abdomen; - Cutting it into pieces with a scalpel, - Using electrical devices called morcellators, which are used to cut the tissue/mass with a rotation movement and take it out of the abdomen. In the known state of the technique, it is quite troublesome to try to cut large tissues/masses with a scalpel through holes/incisions that are 1.5-20m wide and limit the surgeon's movement area. These procedures are tiring, time-consuming and risky for the patient's health. This process can extend the duration of the surgery by 60 to 90 minutes. In addition, the risk of injury or damage to the surrounding tissues is high due to the aforementioned procedures. When using morcellator disintegrator devices, there is a risk that the tissue/mass being removed may spread/scatter into the abdomen in small pieces due to the rotational movement in their working principle. In operations where the morcellator device is used, if the removed tissue is malignant (cancer), the patient faces the risk of metastasis spreading throughout the abdomen. Due to bitter experiences, the use of this device is banned in the United States of America, and in European Union countries it is required that it be used in sterile bags. However, even the use of these bags cannot completely prevent the spread of tissue into the abdomen. Another way to remove the mass from the abdomen at the end of the operation is to make a large incision. This incision eliminates all the advantages of laparoscopic surgery, increases the patient's pain and prolongs the hospital stay, increases the cost of the operation, creates a risk of infection and therefore delays the patient's return to work/social life. Brief Description and Purposes of the Invention: With the invention, the mass that will be removed from the abdomen after the laparoscopic operation will be removed without making an additional abdominal incision during the hysterectomy (uterus removal) surgery; In myomectomy or adnexal mass surgeries, it can be easily removed by disintegrating through a 3 cm incision made at the top of the vagina. The invention consists of two chambered parts that are triangular in shape when viewed from above (Figure 2) and whose cutting faces touch each other when closed (Figure 4), and the holder attached to these cutting chambers. It consists of handles. The two cutting edges/chambers of the invention are designed to enter the abdomen through a 3cm incision when the invention is in the closed position. When these openings enter the abdomen, they are opened with the help of gripping handles, the tissue/mass equal to the volume of the chamber is cut and this mass can be directly removed from the abdomen by keeping the device in the closed position. The tissue/mass can be removed from the abdomen quickly and safely with repetitive movements. Since large-sized tissues/masses can be removed from the abdomen through a maximum incision of 3 cm, with the advantage of the invention, patients are protected from the possible risks of a large incision. Since the invention cuts the tissue/mass directly (it does not rotate like a morcellator device) and is designed to keep the cut piece in its own chamber, there is no risk of the tissue/mass spreading into the abdomen. Find out; It is planned to be produced from stainless steel material that can be used in surgical operations, disinfected and compatible with the human body. It is envisaged that the invention will be used in closed hysterectomy and myomectomy surgeries. According to OECD data, the number of hysterectomies in 2017 increased for Germany. For Türkiye, although the last data date is 2012, the number of hysterectomies is .915° (https://stats.oecd.org/index.aspx?queryid:30l 67). In the United States, the most common operation is hysterectomy. Nowadays, patients want to return to their jobs as soon as possible and the fact that open surgery is more costly and risky directs surgeons towards minimally invasive surgery. However, taking the tissues out of the abdomen creates a problem in this regard. After power morcellation was banned by the FDA in 2014, there was an increase in the frequency of complications related to open surgeries performed in the United States, and the number of blood transfusions increased. Thereupon, ACOG recommended open surgery or vaginal morcellation in a sterile bag for large uteruses and fibroids. In this recommendation, it is stated that attention should be paid to adjacent organ injuries (ACOG COMMITTEE OPINION Number 770). At this point where the technique is stuck, the invention is a strong candidate to be a frequently preferred surgical tool with its new, unique and practical usage features. If the number of myomectomies to be performed is added to the number of hysterectomies, it is obvious that there will be a large number of demands annually in our country, the European Union and the United States. Again, according to OECD data, the number of hysterectomies and myomectomies to be performed in Turkey in 2020 is expected to be approximately 15,000. It is estimated that 30% of this will be performed with closed methods. According to statistical data, the invention can be used in 4500 gynecological operations annually if it is ready in 2020. Closed surgeries are not an area only gynecology is interested in. Now all surgeons want to perform operations with minimally invasive methods. Gallbladder in general surgery. Colon and esophagus operations, prostate and kidney removal surgeries in urology, and arthroscopic procedures in orthopedics are increasingly being performed laparoscopically. This increase brings with it difficulties in removing tissues. The invention can be used to safely remove large masses through small incisions after all abdominal surgeries. Its invention Definitions of Explanatory Figures The following are the figures and related explanations used to better explain the endoscopic tissue cutting and abdominal extraction device developed with this invention: Figure 1. Front view of the invention in the closed state Figure 2. Top view of the invention in the closed condition Figure 3. Front view of the invention in the open condition Figure 4. View of the chamber part and cutting surfaces when the invention is in the open position. Figure 5. Basic design dimensions of the invention (measurements are given in mm) Definitions of the Elements Constituting the Invention. The parts in the figures are included in the figures to better explain the endoscopic tissue cutting and abdominal extraction device developed with this invention. and the parts are numbered, and the equivalent of each number is given below. 1- Mouth 1.1- Upper incisor with chamber 1.2- Lower incisor with chamber 2- Handle 2.1- Connection Hole 3- Handle Detailed Description of the Invention The invention provides a solution to the problem of removing large masses from the abdomen through small-sized incisions after laparoscopic surgery. Removal of a large mass from the abdomen after laparoscopic surgery; It is possible to divide the mass into pieces by making an additional incision the size of the mass, using a morcellator device, and using a scalpel through an additional incision made at the top of the vagina in hysterectomy surgeries, and at the top of the vagina in myomectomy and adnexal mass surgeries. Making a large incision has no place in laparoscopic approaches aimed at minimally invasive surgery. The use of morcellators has been abandoned by many surgeons because it causes the tissues to be removed to spread into the abdomen. Today, removal of large masses from the abdomen is most commonly done by cutting them into pieces with a scalpel through existing incisions. This procedure is difficult, time-consuming and poses a risk of injury to surrounding tissues. Using the invention in question instead of existing methods is a safe, fast and easy solution. The invention consists of mouth (1), handle (2) and handle (3). The mouth part consists of two chambered incisors, the chambered upper incisor (1.1) and the chambered lower incisor (1.2), whose bases (sharp surfaces) face each other and are triangular in shape when viewed from above. In addition to its ease of use, thanks to this design, the invention will be able to enter the abdomen through an approximately 3cm incision used during the operation or opened into the vaginal tray, grasp and cut the mass to be removed from the abdomen, and store the cut piece in its own chamber (1.1, 1.2). Thus, the mass to be removed can be removed without touching other abdominal areas and the incision line. In addition, thanks to the round design on the outside of the mouth (1), it does not harm the surrounding tissues. By serially repeating the incision and removal process, large masses can be removed from the abdomen quickly, safely and without contact with other abdominal parts or the incision site. The invention consists of two identical parts. Each piece has a mouth (1), a handle (2) and a handle (3). The mouth (1) part of the invention is triangular when viewed from above and there is a cutting surface at the base. The width, height and depth of the upper cutter with chamber (1.1) and the lower cutter with chamber (1.2), respectively; They are 25, 11 and 25 mm. The parts of the upper chamber cutter (1.1) and the chamber lower cutter (1.2) facing each other (contacting surfaces when the device is closed) are sharp and designed to cut myoma or uterus. The surroundings of the completely closed part formed by closing the mouth (1) are designed with round curves so as not to damage the surrounding tissues. The mouth (1) parts of the invention are connected to a handle (2). There is a connection hole (2.1) in the middle part of the handles (2). After the connection holes (2.1) are overlapped, these handles (2) are mounted together with a screw or similar element. At the other end of the handle (2) part of the invention, there is a round handle (3) part that the 1st and 4th fingers of the hand can pass through. Find out; It is made of stainless steel material so that it can be used in surgical operations and is compatible with the human body. TR TR TR
