前言導(dǎo)讀
醫(yī)用內(nèi)窺鏡是一種醫(yī)療器械，由可彎曲部分、光源及一組鏡頭組成，用于在內(nèi)窺鏡診療過(guò)程中提供通道、照明，并可以對(duì)體腔、中空器官和身體管道進(jìn)行觀察或操作，其經(jīng)人體的天然孔道，或者是經(jīng)手術(shù)做的小切口進(jìn)入人體內(nèi)。使用時(shí)將內(nèi)窺鏡導(dǎo)入預(yù)檢查的器官，可直接窺視有關(guān)部位的變化，亦可用于手術(shù)或協(xié)助植入治療性人工產(chǎn)品。
相較于傳統(tǒng)醫(yī)學(xué)，微創(chuàng)和無(wú)創(chuàng)的醫(yī)學(xué)提高了診治效率，減輕了患者痛苦，是醫(yī)學(xué)技術(shù)發(fā)展的革命性進(jìn)步，也預(yù)示著未來(lái)醫(yī)學(xué)的發(fā)展方向。內(nèi)窺鏡設(shè)備常搭配內(nèi)鏡診療手術(shù)耗材使用，在內(nèi)窺鏡檢查或手術(shù)中起到活檢、止血、擴(kuò)張、切除等作用。
醫(yī)用內(nèi)窺鏡擁有一個(gè)龐大的產(chǎn)品體系，品類(lèi)眾多，按照鏡體的軟硬程度和應(yīng)用場(chǎng)景，可以分為軟性?xún)?nèi)窺鏡和硬管內(nèi)窺鏡，按照應(yīng)用領(lǐng)域劃分，可以分為消化內(nèi)鏡、呼吸內(nèi)鏡、普通外科內(nèi)鏡、關(guān)節(jié)鏡、脊柱內(nèi)鏡、泌尿外科內(nèi)鏡、胸外科內(nèi)鏡、婦科內(nèi)鏡、鼻咽喉科內(nèi)鏡等。其中，消化內(nèi)鏡主要包括胃鏡、腸鏡等。
醫(yī)用內(nèi)窺鏡廣泛應(yīng)用于眾多臨床科室和應(yīng)用場(chǎng)景，作診療用途。伴隨著技術(shù)的進(jìn)步，內(nèi)窺鏡的應(yīng)用持續(xù)擴(kuò)大至多個(gè)診療過(guò)程中，預(yù)期將推動(dòng)全球?qū)?nèi)窺鏡的需求。

市場(chǎng)概覽
全球醫(yī)用內(nèi)窺鏡市場(chǎng)是全球醫(yī)療器械市場(chǎng)增長(zhǎng)最快的板塊之一。根據(jù)弗若斯特沙利文相關(guān)報(bào)告，于2020年，全球醫(yī)用內(nèi)窺鏡市場(chǎng)的價(jià)值為203億美元，并估計(jì)于2030年將增至396億美元。下圖說(shuō)明全球醫(yī)用內(nèi)窺鏡市場(chǎng)的歷史和估計(jì)市場(chǎng)規(guī)模：

技術(shù)解讀
醫(yī)用內(nèi)窺鏡是一種集光學(xué)、人體工程學(xué)、精密儀器、現(xiàn)代電子、數(shù)學(xué)、軟件等技術(shù)于一體的多學(xué)科系統(tǒng)。醫(yī)用內(nèi)窺鏡通常由可進(jìn)入人體的軟管或硬管、捕獲和傳輸患者內(nèi)部組織器官圖像的透鏡成像系統(tǒng)、對(duì)捕獲的圖像進(jìn)行數(shù)字化處理的圖像處理系統(tǒng)、將數(shù)字化圖像呈現(xiàn)給操作者或觀察者的顯示系統(tǒng)，以及傳輸光線(xiàn)以提高被檢查區(qū)域的可見(jiàn)度的光源系統(tǒng)組成，在某些情況下，還包括一個(gè)額外的工作通道，為手術(shù)過(guò)程中使用的器械提供通路。
醫(yī)用內(nèi)窺鏡主要包括供電模塊、采集模塊、光源模塊以及處理模塊等部分，其組成部分和工作原理如下附圖所示：
然而現(xiàn)行的手術(shù)仍然需要通過(guò)光纖電纜連接到手術(shù)塔上，又是會(huì)絆倒使用者從而帶來(lái)操作不便，更為嚴(yán)重的是這些電纜與患者燒傷和醫(yī)療相關(guān)感染(HAIs)有關(guān)，這會(huì)造成極大的醫(yī)療成本負(fù)擔(dān)，嚴(yán)重甚至?xí)斐刹∪怂劳龅碾[患。
近日，F(xiàn)DA批準(zhǔn)首款且唯一無(wú)線(xiàn)內(nèi)窺鏡----ArthroFree，為內(nèi)鏡技術(shù)帶來(lái)新的發(fā)展方向，ArthroFree通過(guò)消除手術(shù)塔組件（和連接電纜），在整個(gè)醫(yī)療保健系統(tǒng)中增加大量?jī)r(jià)值，通過(guò)提高手術(shù)室的安全性和效率來(lái)降低成本，引起了巨大反響。
另外，知名內(nèi)窺鏡廠(chǎng)商Endoluxe，同樣推出一款無(wú)線(xiàn)內(nèi)窺鏡----Endoluxe eVS，其首款采用 TowerTech技術(shù)的高清無(wú)線(xiàn)內(nèi)窺鏡， TowerTech具有內(nèi)置于攝像機(jī)的所有必要可視化功能，也引起了市場(chǎng)廣泛關(guān)注。
對(duì)于本文，筆者以ArthroFree和Endoluxe eVS為典型代表，對(duì)無(wú)線(xiàn)內(nèi)窺鏡展開(kāi)系統(tǒng)分析。
認(rèn)識(shí)ArthroFree
ArthroFree系統(tǒng)來(lái)自于Lazurite公司，將其專(zhuān)有的低熱、高強(qiáng)度Meridiem光引擎技術(shù)與先進(jìn)的攝像頭、電池和無(wú)線(xiàn)傳輸技術(shù)相結(jié)合，并與患者數(shù)據(jù)控制臺(tái)、手術(shù)顯示器和內(nèi)窺鏡相兼容。該系統(tǒng)旨在通過(guò)節(jié)省成本、提高能源效率和縮短設(shè)置/故障時(shí)間來(lái)提高手術(shù)室的生產(chǎn)率、患者安全性和經(jīng)濟(jì)價(jià)值。模塊化系統(tǒng)還設(shè)計(jì)為與當(dāng)前的手術(shù)室技術(shù)完全兼容。
ArthroFree無(wú)線(xiàn)系統(tǒng)旨在簡(jiǎn)化滅菌，減少設(shè)置和擊穿時(shí)間，并消除手術(shù)塔上對(duì)光源和電源的需求。ArthroFree無(wú)線(xiàn)系統(tǒng)將消除光纖電纜的危險(xiǎn)，以及外科助理對(duì)相機(jī)電纜管理的需求。
ArthroFree無(wú)線(xiàn)手術(shù)系統(tǒng)需要新的信號(hào)傳輸、電源和照明功能，因此，創(chuàng)建了Meridiem照明技術(shù)平臺(tái)，Meridiem是一種固態(tài)、低熱量、高效的照明系統(tǒng)，并且需要的能量只是同類(lèi)有線(xiàn)攝像機(jī)系統(tǒng)的一小部分。
ArthroFree系統(tǒng)中使用的Meridem照明技術(shù)只需傳統(tǒng)手術(shù)攝像機(jī)1%的功率即可獲得可比的照明量，而且該平臺(tái)和設(shè)計(jì)易于擴(kuò)展，并且有望在醫(yī)療保健和其他行業(yè)建立新的節(jié)能照明標(biāo)準(zhǔn)。
專(zhuān)利分析
Lazurite對(duì)ArthroFree系統(tǒng)中和Meridem照明技術(shù)均進(jìn)行了全方位的專(zhuān)利布局，筆者分別從ArthroFree系統(tǒng)中和Meridem照明技術(shù)涉及的相關(guān)專(zhuān)利中擇機(jī)選擇了2組專(zhuān)利進(jìn)行了解析，相關(guān)結(jié)果如下，ArthroFree系統(tǒng)中和Meridem照明技術(shù)的完整專(zhuān)利清單筆者也匯總完成，如若獲取完整專(zhuān)利清單和相關(guān)專(zhuān)利分析可以與筆者取得聯(lián)系，共同交流學(xué)習(xí)：

解決的技術(shù)問(wèn)題 |
Modern endoscopic surgical procedures, which are generally considered quick and simple, actually require a lengthy preoperative period to set up the necessary equipment and require the use of a number of wires and cables that are often draped over patients and can hinder surgeons and their staff. Moreover, although state-of-the-art LED-based systems are more efficient than the older xenon lighting systems, which may use over 1000 watts of power, these newer light source units are still very power intensive, requiring 300 watts or more, most of which is wasted as heat or lost through light leaking from the external light cable. In addition, the wasted heat has been repeatedly cited as the source of operating room fires in cases where the cables were draped over a patient incorrectly or when the heated endoscope met a combustible material. |

技術(shù)方案 |
A wireless imaging system comprising a head unit and a light cable is provided. The head unit comprises a head unit case, a head unit electrical connector, an image sensor, a wireless transceiver, a central processing unit, and a user-input component. The light cable comprises a light cable electrical connector, a power cable, and an integrated light source. The integrated light source comprises an emissive radiation source having a first spectrum, an optical element located to direct emissions from the emissive radiation source, a volumetric spectrum converter, and an optical reflector located about the converter. The converter converts emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum. The reflector reflects the converter emissions towards the output filter. |

解決的技術(shù)問(wèn)題 |
For these reasons, the overall efficiency of the extant designs remains comparatively low, even when LD-based devices (the most efficient design) are analyzed. Furthermore, prior designs that use an LD to provide the primary light input completely saturate the remote phosphor elements. This over saturation can lead to the inadvertent emission of coherent laser light, which can cause damage to sensitive electronics, materials, eyes, and skin. |

An integrated light source includes: an emissive radiation source having a first spectrum; an optical element located to direct emissions from the emissive radiation source; a volumetric spectrum converter located to convert emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum; an optical reflector located about the converter; an output filter, the reflector being located to reflect the converter emissions towards the output filter; and a package body having an internal cavity containing the emissive radiation source, optical element, converter, reflector, and filter, wherein desired light radiates from the cavity through the filter. |

A portable endoscopic inspection system comprises an endoscope having a proximal end with a flanged eyepiece for observation and a distal end with a lens assembly for insertion into a region of interest. A light port transports incident light to the region of interest along an lighting pathway, and reflected light is transported along an imaging pathway from the lens assembly to the eyepiece. A wireless imaging unit comprises a light source which detachably couples to the light port for generating the incident light, and an imaging sensor for recording images of the reflected light from the eyepiece. The wireless imaging unit comprises a variable coupling system which mechanically couples the imaging sensor to the flanged eyepiece independent of the shape and/or size of the flange of the eyepiece. |

目前，對(duì)于醫(yī)用內(nèi)窺鏡設(shè)備而言，依然以國(guó)外企業(yè)為主，上述企業(yè)在一次性、4K、3D、特殊光醫(yī)、超細(xì)等多個(gè)領(lǐng)域占據(jù)國(guó)內(nèi)市場(chǎng)大部分份額，不過(guò)隨著國(guó)內(nèi)重視程度不斷提高的情況下，中國(guó)公司蓄勢(shì)待發(fā)，在一片被普遍看好的市場(chǎng)中開(kāi)始暗流涌動(dòng)，隨著各個(gè)“卡脖子”技術(shù)不斷攻克，國(guó)產(chǎn)醫(yī)用內(nèi)窺鏡一定會(huì)在近幾年實(shí)現(xiàn)重大突破和問(wèn)世。
