一种导丝、导引装置及空肠造瘘系统Guide wire, guide device and jejunostomy system

技术领域technical field

本发明涉及医疗器械领域,具体是一种导丝、导引装置及空肠造瘘系统。The invention relates to the field of medical equipment, in particular to a guide wire, a guide device and a jejunostomy system.

背景技术Background technique

食管癌是临床上常见的消化道肿瘤,如果患者得不到及时的治疗,随着病情的发展最终会因无法进食而衰竭死亡。患者术前多有不同程度的吞咽困难、进食梗阻等症状,加之术后患者消化道重建,如果营养治疗不到位就会出现营养不良而增加患者术后并发症;针对此类患者,通常采用肠外营养以及肠内营养这两种营养支持途径。肠外营养主要是静脉营养,长期肠外营养支持后肠道形态和功能会发生异常,可损害机体的免疫系统,长期肠外营养甚至会导致肠道黏膜的萎缩。相比较而言,肠内营养更符合机体的生理需求,能够维持肠道黏膜的正常结构和功能。肠内营养支持常用的有鼻肠营养管和空肠造瘘管,鼻肠营养管适用于肠道功能正常者,空肠造瘘管适用于食管癌手术消化道再造患者,特别是术后需要进行放疗或者化疗的病人,一般在腹腔镜下进行,该方法中的空肠造瘘需要在找到直肠后将直肠截断,将无法工作的一端缝合起来,尚能工作的一端与体外的液体装置等连接,通过体外的液体装置等把营养液之类的输入体内供患者吸收。Esophageal cancer is a clinically common digestive tract tumor. If patients do not receive timely treatment, they will eventually fail and die due to inability to eat as the disease progresses. Patients often have different degrees of dysphagia, feeding obstruction and other symptoms before operation. In addition, postoperative digestive tract reconstruction, if nutritional therapy is not in place, malnutrition will occur and postoperative complications will increase; for such patients, intestinal Parenteral nutrition and enteral nutrition are two ways of nutritional support. Parenteral nutrition is mainly intravenous nutrition. After long-term parenteral nutrition support, the intestinal morphology and function will be abnormal, which can damage the body's immune system. Long-term parenteral nutrition may even lead to atrophy of the intestinal mucosa. In comparison, enteral nutrition is more in line with the physiological needs of the body and can maintain the normal structure and function of the intestinal mucosa. Enteral nutrition support is commonly used with nasoenteric feeding tube and jejunostomy tube. Nasoenteric feeding tube is suitable for patients with normal intestinal function, and jejunostomy tube is suitable for patients with digestive tract reconstruction after esophageal cancer surgery, especially those who need radiotherapy or chemotherapy after surgery. For patients, it is generally performed under laparoscopy. The jejunostomy in this method needs to cut off the rectum after finding the rectum, suture the non-working end, and connect the working end to the liquid device outside the body. Liquid devices and the like are used to inject nutrients such as nutrient solution into the body for absorption by the patient.

上述空肠造瘘方案可解决患者空肠营养输入的问题,但上述方式需要先在胃壁上形成一个孔洞,通过该孔洞将空肠营养管以盲插的方式植入空肠内,插管难度大,置入困难;一旦无法通过胃腔将空肠营养管放入目标位置,则在胃壁上预先形成的孔洞会给病人带来额外的创伤且还无法达到空肠营养管植入的目的,因此亟待解决。The above-mentioned jejunostomy solution can solve the problem of jejunal nutrition input for patients, but the above-mentioned method needs to form a hole in the stomach wall first, and insert the jejunal nutrition tube into the jejunum through the hole in a blind way, which is difficult to insert. Difficulty; once the jejunal feeding tube cannot be put into the target position through the gastric cavity, the pre-formed hole on the stomach wall will bring additional trauma to the patient and the purpose of jejunal feeding tube implantation cannot be achieved, so it needs to be solved urgently.

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

请参阅图1~6,本发明实施例中,一种导丝、导引装置及空肠造瘘系统,包括导芯,这里的导芯用于引导放置导引组件2,导芯内开设有工作通道33以使得导芯可从口腔或鼻腔沿消化道进入空肠内后,使导引组件2自体外沿工作通道33抵达空肠腔内。Please refer to Figures 1 to 6. In an embodiment of the present invention, a guide wire, a guide device, and a jejunostomy system include a guide core, where the guide core is used to guide the placement of the guide assembly 2, and a working The channel 33 allows the guide core to enter the jejunum from the oral cavity or nasal cavity along the alimentary canal, and then the guide assembly 2 reaches the cavity of the jejunum from the outside along the working channel 33 .

导芯优选为内窥镜3,内窥镜3可弯曲且材质柔软,内窥镜3的前端具有特定的弯曲度,其材质可以为记忆合金,从而可在受外力所用下改变弯曲度后迅速恢复。Guide core is preferably endoscope 3, and endoscope 3 is bendable and material is soft, and the front end of endoscope 3 has specific degree of curvature, and its material can be memory alloy, thereby can change the degree of curvature rapidly under the use of external force. recover.

弯曲度的设计可以配合内窥镜3放置过程中的前进、后退以及旋转操作,提高了操作者的可视范围以便于后续寻找最佳的空肠内置管位置。The design of the curvature can cooperate with the forward, backward and rotating operations during the placement of the endoscope 3, which improves the operator's visual range and facilitates the subsequent search for the best jejunal tube position.

为实现内窥镜3的可视化导航,内窥镜3如图3所示,前端布置有发光元件32和感光元件31。In order to realize the visual navigation of the endoscope 3, as shown in FIG.

其中,发光元件32作为光源,包括一根或多根光纤,从而可发射波长不同的光纤束。一个或多个成像光纤束沿内窥镜3的中心轴线纵向地延伸,一个或多个成像光纤束中的每个成像光纤束在其前光纤端面处,附接有与该成像光纤束尺寸相当的物镜。Wherein, the light-emitting element 32 is used as a light source and includes one or more optical fibers, so that optical fiber bundles with different wavelengths can be emitted. One or more imaging fiber bundles extend longitudinally along the central axis of the endoscope 3, each imaging fiber bundle in the one or more imaging fiber bundles is attached at its front fiber end face with a the objective lens.

通过发射波长不同的光纤束的配合,可以满足医生临床操作的个性化需求,比如可以根据观察的视野明暗情况调整视野亮度,主要起到对目标位置进行照明的作用,便于临床医生及时准确掌握目标位置的导引组件2的实际置入情况。Through the cooperation of optical fiber bundles with different emission wavelengths, it can meet the individual needs of doctors in clinical operations. For example, the brightness of the field of view can be adjusted according to the brightness and darkness of the observed field of view, which mainly plays the role of illuminating the target position, so that clinicians can accurately grasp the target in time. The actual placement of the guide assembly 2 of the position.

感光元件31为电耦合器件、固态图像传感器、接触式图像传感器中的一种。发光元件32可朝向目标位置发射成像探测光,并接收来自目标位置的成像响应光,因此可以基于成像响应光的信号强度在成像光纤束中的分布情况来确定内窥镜3的所在位置相对于目标位置的中心方向偏离情况。The photosensitive element 31 is one of an electrical coupling device, a solid-state image sensor, and a contact image sensor. The light-emitting element 32 can emit imaging detection light toward the target position, and receive imaging response light from the target position, so the position of the endoscope 3 can be determined based on the distribution of the signal intensity of the imaging response light in the imaging fiber bundle. The deviation of the center direction of the target position.

感光元件31中存在光敏单元,可以将图像转换为电信号,进而通过模数转换器将电信号转换为可供医生观察地数字图像,可以完成数据的采集、图像的记录等,电耦合器件、固态图像传感器、接触式图像传感器的采光效率高,因此记录的图像可以满足临床上对高像素高画质的可视化要求,便于医生观察。There is a photosensitive unit in the photosensitive element 31, which can convert the image into an electrical signal, and then convert the electrical signal into a digital image that can be observed by a doctor through an analog-to-digital converter, and can complete data collection, image recording, etc., electrical coupling devices, Solid-state image sensors and contact image sensors have high light-gathering efficiency, so the recorded images can meet the clinical visualization requirements of high pixels and high quality, which is convenient for doctors to observe.

感光元件31还可选择为CMOS(complementarymetaloxide semiconductor)传感器或CCD(chargedcoupleddevice)传感器。The photosensitive element 31 can also be selected as a CMOS (complementary metal oxide semiconductor) sensor or a CCD (charged coupled device) sensor.

其中,CMOS即互补性金属氧化物半导体,主要是利用硅和锗两种元素所做成的半导体,通过CMOS上带负电和带正电的晶体管来实现基本的功能,这两个互补效应所产生的电流即可被处理芯片记录和解读成影像。CCD的特点是灵敏度高,但响应速度较低,不适用于高清监控摄像机采用的高分辨率逐行扫描方式。相比较而言,CMOS传感器通常包含:一个图像传感器核心(是将离散信号电平多路传输到一个单一的输出,这与CCD图像传感器很相似),所有的时序逻辑、单一时钟及芯片内的可编程功能,比如增益调节、积分时间、窗口和模数转换器。即CMOS传感器包括图像阵列逻辑寄存器、存储器、定时脉冲发生器和转换器在内的全部系统。与传统的CCD图像系统相比,把整个图像系统集成在一块芯片上不仅降低了功耗,而且具有重量较轻,占用空间减少以及总体价格更低的优点,更适用于临床医学影响的采集与捕捉。Among them, CMOS is a complementary metal oxide semiconductor, which is mainly a semiconductor made of silicon and germanium. The basic functions are realized through negatively charged and positively charged transistors on CMOS. These two complementary effects produce The current can be recorded and interpreted into an image by the processing chip. CCD is characterized by high sensitivity, but low response speed, which is not suitable for the high-resolution progressive scanning method used by high-definition surveillance cameras. In comparison, a CMOS sensor typically includes: an image sensor core (which multiplexes discrete signal levels into a single output, much like a CCD image sensor), all sequential logic, a single clock, and on-chip Programmable functions such as gain adjustment, integration time, window, and analog-to-digital converter.
