A Surgical Tool for Force and Ranging

Abstract

The invention discloses a surgical tool for force and distance measurement. The surgical tool solves the problems that the tapping depth is not easy to grasp and the stress is not easy to measure in the prior art. The penetration distance of the surgical tool can be detected in real time. The stress of the surgical tool can be detected in real time. Working requirements of different types can be met by replacing a tool bit. According to the technical scheme, the surgical tool comprises a knife handle, a knife rod and a knife head. One end of the knife rod is detachably connected with the knifehandle, and the other end of the knife rod is detachably connected with the knife head. A transparent casing is installed on the outer side of the knife rod. An illuminating lamp is fixed on one sideof the knife rod. The knife rod comprises a thrust mechanism. The thrust mechanism is connected with a force measuring mechanism and can drive the force measuring mechanism to move.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a surgical tool for force measurement and distance measurement. Background technique

[0002] In current orthopedic surgery, bone internal fixation is mainly done by implanting metal materials into the human body, and then fixing them with steel plates, steel nails, etc., and taking out the steel plates and steel nails after the broken bone has healed. Before the steel nail is fixed, the bone needs to be drilled. Due to differences in the strength of the outer wall and inner bone of the same person, and individual differences among different people, doctors cannot accurately grasp the depth of the opening. If the hole is too shallow, the fixation of the steel nail will be unstable, which will affect the treatment effect, and if the hole is too deep, it will cause damage to the bone.

[0003] Currently, physicians determine the depth of the opening simply by marking ...
