The application provides a synchronous lifting type latex balloon forming device, which comprises a support frame, a driving mechanism, a transmission mechanism, a lifting mechanism, a latex tank and a mold. The driving mechanism comprises a driving motor and a driving wheel, the transmission mechanism comprises a synchronous belt, two driven wheels and two parallel ball screws, and the lifting mechanism comprises a synchronous plate, four vertical columns and a support. The driving motor drives the driving wheel, which is connected to the driven wheels through the synchronous belt, so that the two ball screws rotate synchronously, the synchronous plate, the vertical columns and the support are lifted, and the mold reciprocates along the axial direction of the first ball screw and the second ball screw from the initial position to the inner bottom groove of the latex tank. By controlling the operation time of the motor, stable lifting without shaking is realized, and the problems of uneven thickness and wavy lines of the balloon forming are solved.

A balloon catheter with positioning and protection functions is used for percutaneous microballoon compression surgery to treat trigeminal neuralgia. It includes a balloon assembly (1) and a catheter assembly (2). The balloon assembly (1) includes a first marker point (11), a second marker point (12), a latex balloon (13), and a third marker point (14). The latex balloon (13) consists of two parts. Its distal part has a smaller outer diameter after inflation and serves as the positioning part (131). Its proximal part has a larger outer diameter after inflation and serves as the compression part (132). The second marker point (12) is located at the junction of the positioning part (131) and the compression part (132) of the latex balloon (13) when it is inflated to the normal size. The positioning step on the latex balloon avoids excessive compression of the posterior fossa during the operation. The location of the balloon step is marked by the second marker point. With the help of preoperative 3D modeling, the balloon position is accurately determined, which reduces the difficulty of the operation.
