尽管中国的放疗事业取得了辉煌的进步,但是对中国这样一个具有13亿人口、经济体量世界第二的发展中国家,我们面临着既与发达国家也与一般发展中国家不同的市场局面。从技术上来看,随着D-IMRT、IGRT、IMAT等临床技术的涌现和使用,国产放疗设备特别是医用加速器设备与国外设备在这方面的技术差距不是拉近了,而是距离越来越大福彩3d跨度走势图。因而需要我们既要突破我们国产设备惯常的放疗市场的定位思维,又要具备开拓创新的能力和市场魄力,同时还需要提升自身的综合竞争能力,才能将国产医用加速器推向前进。



国产放疗设备的市场需求



关于放疗设备(包含电子加速器、质子、重离子、伽玛刀和钴-60常规放疗机、射波刀等)的市场容量,专家们的宏观估计一向比较统一,即按照WHO提出的百万人均拥有加速器为2~3台的标准来进行估算。中国从20世纪90年代前的百万人口0.24台放疗设备的拥有量到如今的百万人口1.42台(加速器)的拥有量,已然取得了很大的进展,但是与WHO的推荐值还有较大差距。与美国(12.4台)和法国(7.5台)相比,差距就更明显了。所以,有的专家根据2015年新增429万肿瘤患者(需要接受放疗的新发病例占50%)的数据静态估计,2015年我国放疗设备的市场缺口在4000台左右(1台放疗设备平均年治疗500名患者)

广东威达医疗器械有限公司:低能6MV医用电子加速器为主,14MeV中能医用电子加速器为辅,共计销售超过100台,鼎盛时期年装机30多台,推出的中能机总销台量以个位数计。目前,该公司于21世纪初倒闭。


北京医疗器械研究所:低能6MV医用电子加速器为主,14MeV中能医用电子加速器为辅,共计销售超过200台,鼎盛时期年销售量超过30台,中能加速器总计销售量也就10台左右。目前,该公司于2005年被Elekta公司收购。


山东新华医疗器械公司:低能6MV医用电子加速器和中能医用电子直线加速器,鼎盛时期年销售量40台左右,中能机年销量以个位数计。该公司是目前国产加速器的主力军之一。


江苏海明医疗器械有限公司:18MeV中高能医用电子直线加速器为主,目前年销售量为个位数。


成都利尼克医学技术发展有限公司福彩3d跨度走势图:14MeV中能医用电子直线加速器,目前年销售个位数以内。


由上面的相关信息可见,从市场份额来看,国产机的年度市场占有率只处于10%~20%内:(1)国产加速器市场基本上还是几十年雷打不动的由低能机为主导,占国产加速器市场份额的70%以上;(2)国产中能机在中国放疗市场的占有率可以忽略不计


换言之,国产加速器目前在市场上的表现和有关专家的判断完全不匹配:国产加速器销售量与市场容量的判断不匹配、国产中能机销售量与有关专家对国产加速器发展趋势的判断不匹配,可以说国产加速器的发展现状令人极感失望。

如果我们检视国外加速器品牌的竞争对手,发现这些品牌公司对于数量庞大的县市级基层医院基本上是放弃的,而国产厂家在没有充分分析这种放弃的深层次原因的前提下视这种国外厂商所放弃的市场为自己的市场机会,于是国产加速器厂家基于图2这种金字塔式的市场模型进行判断和分析,将国产放疗细分市场锁定在满足基层医院也就是金字塔底层的医院的需求,并由此开展了一系列的研发、市场投入、生产和销售工作。


相对而言,这类基层医院对放疗产品的特点是:(1)对放疗设备的性能和功能需求不高,基本要求是具备常规放疗、适形放疗能力,最多具备静态调强功能就满足了。大部分还希望设备必须有电子线的治疗能力。(2)这个市场对于价格成本极其敏感。

金字塔模型告诉我们福彩3d跨度走势图:(1)国产设备的研发首先要针对的是基层医院需求;(2)基层医院对设备的要求是低成本低价格,满足放疗的基本临床需求;(3)在当今国产设备在市场的表现来看,对国产设备的发展前景不乐观;(4)无法用这种模型解释国产设备市场表现的低迷现状;(5)基于国产设备市场上的低迷表现,该模型导致对加大研发投入的信心不够。


菱形结构模型告诉我们福彩3d跨度走势图:(1)国产设备发展前期的细分市场对象错误,应该予以修正,市场对象应该锁定为三级医院;(2)完全可以解释在国产设备在市场对象错误前提下开发出来的低成本国产设备在真实市场中的销售量低迷的表现;(3)低成本低利润产品必须通过高数量生产才能获取进一步发展的空间。菱形结构告诉我们,当我们将市场细分对象确定为基层医院后,这一期望值将落空。这一结论也与多年来国产加速器设备难以为继的现状相吻合;(4)国产设备应该针对三级医院市场需求进行研发,且完全有巨大的发展机会和空间,这一点在Varian和Elekta表现得很明显;(5)国产加速器应该跟踪国际品牌的发展机会,并保持一种接近和超越的信念,创新求变,实现弯道超车。

1、  医院购买中高能加速器的目的在哪里?真的是为了电子线吗?福彩3d跨度走势图我们知道电子线的临床应用只占到15%,如果只是为了这15%的电子线的临床需求,从资源的配置和优化来考虑,合理的逻辑应该是一家医院只需要1台中高能机用于专门提供电子线治疗,其他都是低能机才对!如果不是只为了电子线的需求,那么,他们又是在为了什么?如何解释电子线在临床应用只占到15%左右的需求情况下,医院设备的采购却依然集中在中高能机上?


2、  我们明明现在的临床发展是在向精确放疗的方向进步,也知道适形、调强、IGRT以及后来发展出来的VMAT等其他的精确放疗手段,在6MV低能机上也可以进行,可参照的对象是TOMOTHERAPY、UNIQUE以及CYBERKNIFE,可是国外主流厂商为什么偏偏将这些相对高端的功能配置主要只和中高能机集成?


要回答这个问题,需要从市场细分产品市场策略两个方面来解答:

于是问题来了



这个市场到底是需要什么?准确地回答这个问题的唯一途径是回到临床需求上也就是应用端需求来判断。其实临床机构本质上不关心设备的具体形态和产品类型,而是关心相关产品能否提供给临床机构有效的治疗手段、舒适的治疗工具以及可靠的管理程序。从这一点来看,高端设备无论是ACCURAY的TOMO和CYBERKNIFE、Elekta的VERSA HD还是Varian的TUREBEAM和EDGE,其实都是满足临床特定应用需求的典范!这些满足临床需求的精确放疗工具其实与产品是否是低能机、中能机还是高能机无关!也与产品形态无关!

常规放疗时代,由于临床技术相对比较简单,所以对放疗设备的功能需求也就比较单一,为了解决4/6MV低能机所不具备的电子线治疗能力,发展中能机和高能机成为解决浅层肿瘤治疗需求的不多的选择。但这种差异化需求只是当时的一个时代的产物,不必要也不应该将其固化为行业的发展方向,机械发展论是不可取的。随着精确放疗时代的来临和普及,随着临床技术和手段的丰富以及用户临床体会越来越深刻,其对设备的应用需求也就趋向多元。如果我们不想满足于跟随行业领军者的技术路线,就应该将更多的关注点放在精确放疗层面上的临床需求上,收集临床对加速器在放疗应用过程中值得继承和需要改善的建议,有针对性的和有意识地解决临床医疗中的不满足或不能接受的痛点,通过和医疗单位的合作,提出我们自己相应的解决方案,提升产品应用过程中的舒适度,这才是国产加速器差异化设计的真正来源。
