Abstract

The invention relates to the technical field of medical instruments, in particular relates to a medical surgical needle holder. The medical surgical needle holder comprises two units of needle holder bodies which are relatively arranged in upper and lower positions, clamping force can be shifted by the needle bodies following the size differences of the clamped surgical needles, so as to ensure that forces are received evenly by the clamped operation needles. The medical surgical needle holder has the beneficial effects that the overall structure is simple, a push pipe relying on the external force is moved forward relative to the connecting rod and the clamping part of the needle holder is driven to close the clamping stitches, when the external force vanishes, the push pipe is returned to its original position, an elastic piece relying on its own elasticity is gradually turned on from a closed state, and the needle holder is driven to gradually open. The needle holder is easy to operate, lower in manufacturing difficulty and production cost, easy to clean and disinfect, and not easily damaged, the service life of the needle holder is lengthened, the needle holders of the nitinol material have super elasticity, the sewing needle receives force evenly during the clamping process and is not easily broken, so that the operation risk is reduced, and the medical surgical needle holder is good in practicality.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical surgical needle holder. Background technique [0002] The needle holder is one of the commonly used surgical instruments. At present, the needle holder is a stainless steel multi-piece structure, which is combined through a four-link hinge mechanism. One end of the four-link hinge mechanism is connected to the needle holder, and the other end is connected to the handle by a steel wire. The traction connection, the handle pulls or loosens the steel wire, thereby controlling the opening and closing of the needle holder, and realizing functions such as clamping the needle. Due to the fine structure of the four-link hinge mechanism, not only the manufacturing process is more complicated, which increases the production cost, but also the gaps of the four-link hinge structure are difficult to clean and disinfect after use, which affects the safety and sanitation o...
