Description

一次性膀胱镜鞘 技术领域  Disposable bladder mirror sheath
本发明涉及一种微创手术器材,具体涉及一种与内窥镜配套使用的一次性膀 胱镜鞘。 背景技术  The present invention relates to a minimally invasive surgical instrument, and more particularly to a disposable bladder sheath sheath for use with an endoscope. Background technique
膀胱镜技术在泌尿科是一种最基础的内窥镜技术, 己有超过 100年的历史, 应用范围很广。它是将内窥镜镜体置入膀胱镜鞘的内窥镜通道,经由膀胱镜鞘的 工作通道放入器械, 通过病患的尿道, 将膀胱镜插入到膀胱, 进行膀胱内的探查 与治疗。  Cystoscopy is one of the most basic endoscopic techniques in urology. It has a history of more than 100 years and has a wide range of applications. It is an endoscope channel in which the endoscope body is placed in the cystoscope sheath. The instrument is placed in the working channel of the cystoscope sheath, and the cystoscope is inserted into the bladder through the urethra of the patient to perform exploration and treatment in the bladder. .
目前膀胱镜鞘材料均是金属,呈圆形,进入尿道时对尿道粘膜有一定的损伤, 而且因购买膀胱镜价格比较昂贵, 一般医院一个膀胱镜要用 5〜10年。长期应用 导致水垢、锈斑在膀胱镜内腔和镜外鞘大量堆积,应用时加重对尿道粘膜损伤及 交叉感染。 虽然在两次膀胱镜检査的间隔中, 要对器械进行消毒, 但由于膀胱镜 应用广,手术量大,常常因为消毒不完全,而造成病患之间互相交叉感染。同时, 对于需要实行输尿管镜手术的病患,也需要先放入膀胱镜找到输尿管口,放入一 支导引钢丝后,将膀胱镜退出,输尿管镜沿着导引钢丝进入膀胱再进入输尿管实 行手术, 加重对尿道损伤。 发明内容  At present, the bladder sheath material is metal, round, and has certain damage to the urethra mucosa when entering the urethra, and because the price of the bladder mirror is relatively expensive, a cystoscope in a hospital should be used for 5 to 10 years. Long-term application causes scale and rust to accumulate in the lumen of the cystoscope and the outer sheath of the mirror. When applied, the mucosal damage and cross infection of the urethra are aggravated. Although the instrument should be sterilized during the interval between the two cystoscopy, due to the wide application of the cystoscope and the large amount of surgery, the patients are often cross-infected due to incomplete disinfection. At the same time, for patients who need to undergo ureteroscopy, it is also necessary to put a cystoscope to find the ureteral orifice, put a guide wire, and then withdraw the cystoscope. The ureteroscope enters the bladder along the guide wire and then enters the ureter. Surgery, aggravating damage to the urethra. Summary of the invention
本发明所要解决的技术问题是提供一种对病患尿道粘膜损伤少、操作方便、 价格便宜的一次性膀胱镜鞘。  The technical problem to be solved by the present invention is to provide a disposable cystoscope sheath which has less damage to the urethral mucosa of the patient, is convenient to operate, and is inexpensive.
为达到上述目的, 采用的技术方案是: 一次性膀胱镜鞘, 包括镜鞘内置的 内窥镜通道和工作通道, 所述内窥镜通道侧面置有进、 出气阀门, 镜鞘的后端相 连接双孔或单孔连接器,其特征在于:所述内窥镜通道与所述工作通道平行连接, 内腔相通, 所述内窥镜通道为医用硬塑料制成, 横截面呈带缺口的椭圆形状, 缺 口的轴向边沿与所述工作通道截面缺口的轴向边沿相接,工作通道以硅胶软质材 料制成。 所述双孔连接器或单孔连接器的双孔或单孔通道端部外接抗逆流封帽。 本发明除了用于一次性膀胱镜鞘外, 还可用作输尿管镜鞘用于输尿管镜手 术。 In order to achieve the above object, the technical solution adopted is: a disposable cystoscope sheath, including an endoscope channel and a working channel built in the mirror sheath, the side of the endoscope channel is provided with an inlet and outlet valve, and the rear end phase of the sheath sheath Connecting a double-hole or single-hole connector, wherein the endoscope channel is connected in parallel with the working channel, and the inner cavity is connected, and the endoscope channel is made of medical hard plastic, and the cross section is notched. The elliptical shape, the axial edge of the notch is in contact with the axial edge of the cross section of the working channel, and the working channel is made of a soft silicone material. The double-hole or single-hole channel end of the two-hole connector or the single-hole connector is externally connected to the anti-backflow cap. In addition to being used for a disposable cystoscope sheath, the present invention can also be used as a ureteroscope sheath for ureteroscopic surgery.
本发明的有益效果在于: 由于内窥镜通道呈椭圆形, 减少了插入口面积, 进行膀胱镜手术时,它的直径可以比传统膀胱镜的直径小, 经尿道进入膀胱对尿 道的损伤也就比较小,病患感觉比较舒适;椭圆形鞘的下半部的工作通道为硅胶 软材料制成, 有一定的弹性, 相对增大了工作通道的空间, 可放入 1〜2个器械, 可多通道器械操作,手术操作方便;所述膀胱镜鞘医用硬塑料和硅胶软材料制作 价格低, 一次性使用, 清洁卫生, 避免了病患互相之间交叉感染。  The beneficial effects of the invention are as follows: since the endoscope channel is elliptical, the insertion port area is reduced, and when the cystoscopic surgery is performed, the diameter thereof can be smaller than that of the conventional cystoscope, and the transurethral bladder enters the bladder and damages the urethra. Smaller, the patient feels more comfortable; the working channel of the lower half of the elliptical sheath is made of soft silicone material, which has a certain elasticity, which increases the space of the working channel, and can be put into 1~2 instruments. Multi-channel instrument operation, convenient operation and operation; the bladder mirror sheath medical hard plastic and silicone soft material are inexpensive to manufacture, disposable, clean and hygienic, and avoid cross-infection between patients.
做输尿管镜时, 本发明还可作为输尿管镜的外鞘使用, 同时监视膀胱及输 尿管的图像, 节省手术时间, 手术更安全。 附图说明  When the ureteroscope is used, the present invention can also be used as an outer sheath of a ureteroscope, and simultaneously monitor images of the bladder and the ureter, saving operation time and making the operation safer. DRAWINGS
