    摘要： A combined surgical needle-suture device is disclosed in which the suture is received into a socket, or recess, formed within the blunt end of the needle, the entrance to the socket being defined by a circumferential sloping surface which terminates at its outer end in a circumferential cutting edge which provides quick and convenient suture cut-off capability when severing of the suture from the needle is desired.

    摘要： A surgical electrode consisting of an insulated stainless steel wire having surgical needles conductively affixed at one or both ends, at least one needle having a pointed end and a nonpointed end with a blind hole or flange in the nonpointed end thereof, and the blunt end of a blunt pointed pin fitted into said hole or flange and a crimp in said nonpointed end of the needle retaining said pin in said hole or flange with controlled pull-out characteristics, said pin conductively and permanently affixed at the other end to said wire, whereby said pin may be pulled out of said blind hole or flange and the blunt end of said pin used as an electrical jack for connection to a pacemaker or similar electric current generating or monitoring device. The electrodes are particularly useful as temporary heart pacer electrodes for cardiac stimulation during and after surgical operations.

    摘要翻译： 一种手术电极，其由绝缘不锈钢丝组成，其外科手术针导电地固定在一端或两端，至少一个具有尖端的针和在其非点的末端具有盲孔或凸缘的非点端， 安装在所述孔或凸缘中的钝针尖和在所述针的所述非点端部中的压接部，其将所述销保持在所述孔或凸缘中并具有受控的拉出特性，所述销在另一端导电地且永久地固定在所述线上，由此 所述销可以从所述盲孔或凸缘中拉出，并且所述销的钝端用作连接到起搏器或类似的电流产生或监测装置的电插座。 电极在外科手术期间和之后用于心脏刺激的临时心脏起搏器电极特别有用。
