Provided are a pressure-pump cartridge and a pressure pump, where the pressure-pump cartridge includes a cylinder, where the cylinder has a first chamber, a piston chamber and a second chamber hat are in communication in sequence, and the piston chamber is used for being in sealing fit with a piston. An end of the first chamber remote from the piston chamber is provided with a first opening allowing entry of the piston, and during installation, the piston enters the first chamber by the first opening and enters the piston chamber after passing through the first chamber, and meanwhile, the first chamber is configured to be in a clearance fit with the piston, such that the size of the first chamber is larger than that of the piston.

A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.
