Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a drilled bone hole depth measuring device. The drilled bone hole depth measuring device comprises a linear probe capable of being inserted into a drilled bone hole, a cylinder and a scale ruler. The probe is installed in a probe sleeve, and a right-angle hook used for positioning the outer surface of the far end of the drilled bone hole is arranged at the far end of the probe. The near end of the probe sleeve is installed in the cylinder through a plug with the far end in a spherical surface shape. The scale ruler is installed in the cylinder, the far end of the scale ruler is connected with a probe cylinder in an inserted mode, the near end of the scale ruler stretches out of the cylinder, a blind hole is formed in the scale ruler in the radial direction, a spring and a ball are arranged in the blind hole from bottom to top, a section of clamping groove is formed in the inner wall of the far end of the cylinder, and the ball is connected with the clamping groove in a sliding mode. By means of the drilled bone depth measuring device, medical personnel can accurately read measurement values, and thus the depth of the bone hole can be easily and accurately measured.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a bone drilling depth measuring device. Background technique [0002] During surgical osteosynthesis, surgeons often need to be able to accurately measure the depth of a bone hole in order to select a suitable length of fastening screw. In some cases, selecting the appropriate length of the fastening screw is important to avoid complications, because if the fastening screw is too long, the fastener may protrude from the bone and injure the adjacent soft tissue of the body. [0003] At present, most of the depth-sounding devices used for the measurement of bone holes are unreasonable in design, insensitive to the movement of the scale, and inconvenient for positioning and measurement, resulting in inaccurate measurement accuracy, and inaccurate measurement values ​​will lead to tight selection in the next operation. The inaccurate specification of the leng...
