Publication number: 20200038595Abstract: The present invention provides medical syringe for preventing needle-stick injury, wherein an inner diameter of a middle part of an elastic disengaging ring is larger than an inner diameter of a front part and an inner diameter of a rear part. The elastic disengaging ring is located between a distal wall of a syringe barrel and a needle. When the middle part of the elastic disengaging ring plugged onto the conical fitting of the syringe barrel is radially pinched flat, the proximal end of the elastically deformed elastic disengaging ring leans against the distal wall of the syringe barrel, and the front end of the elastically deformed elastic disengaging ring leans against the proximal end of the needle and pushes the needle to move forward, so that the needle is disengaged from the conical fitting of the syringe barrel.Type: ApplicationFiled: February 18, 2019Publication date: February 6, 2020Applicant: SHANGHAI BOQIA MEDICAL DEVICE CO., LTD.Inventors: YIYI ZHANG, ZUREN ZHANG, WEIHUA XU

Patent number: 9216020Abstract: An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.Type: GrantFiled: December 14, 2010Date of Patent: December 22, 2015Assignee: CHANGZHOU KANGDI MEDICAL STAPLER CO., LTD.Inventors: Zuren Zhang, Yikang Jiang, Zhenyu Jiang, Rong Ji, Yiyi Zhang, Weihua Xu, Dongkun Yuan, Qi Yang
