Springing replaceable hand surgical tap holder

Abstract

The invention relates to a medical instrument, in particular to a springing replaceable hand surgical tap holder, which consists of a knob, a switch strip, an annular bump, a rotating shaft seat, a sliding chute, a sliding shaft seat, a sliding shaft, a dead bolt, a sealing ring, a spring, an operating rod, a replaceable head, a blind hole and a locking hole. The operating rod is a cylinder, wherein an axial blind hole is formed in the center of the lower end of the cylinder. The upper end of the operating rod is integrated with the knob. The replaceable head consists of a rod part, and a tap head and a base which are integrated with the two ends of the rod part respectively, wherein the base and the rod part are coaxial cylinders; the rod part has a diameter smaller than that of the base; a circular hole is formed on the sidewall of the base; and the base is positioned in the blind hole, and forms assembly clearance fit with the blind hole. The springing replaceable hand surgical tap holder greatly reduces the cost of a surgical instrument, avoids waste and simultaneously saves a sterilization space and transportation cost.

Description

technical field [0001] The invention relates to a medical device, in particular to a spring pressure replaceable hand surgical screw tap holder. Background technique [0002] Most of the existing taps of different types used in hand surgery are equipped with their own holders. Although this design is simple in structure, it is in good condition because the taps are easily damaged and they are an inseparable whole with the holder. The holder also can become waste product because of the damage of screw tap, and this makes the cost of surgical instrument too high, causes waste. At the same time, since the medical instruments need to be sterilized before and after the operation, the holder will occupy a large space after entering the disinfection equipment, which increases the cost of disinfection and reduces the efficiency of disinfection. [0003] In order to avoid the above problems, it is necessary to make the tap and its holder detachable, but it is necessary to make it po...

Problems solved by technology

[0002] Most of the existing taps of different types used in hand surgery are equipped with their own holders. Although this design is simple in structure, it is in good condition because the taps are easily damaged and they are an inseparable whole with the holder. The holder will also become a waste product due to the damage of the tap, which makes the cost of the surgical instrument too high and causes waste

At the same time, since medical instruments need to be sterilized before and after surgery, the holder will occupy a large space after entering the disinfection equipment, which increases the cost of disinfection and reduces the efficiency of disinfection.

[0003] To avoid the above problems, it is necessary to make the tap and its holder separable, but it is necessary to make it possible for the two to be quickly connected, quickly disassembled, and replaced, and to be stable, firm, and free from looseness. This is a problem that those skilled in the art have been eager to solve but have not been able to thoroughly solve for many years
