Description

Orthopedics positioning needle capable of sounding Technical Field The utility model relates to the technical field of medical auxiliary instruments, in particular to a depth-measurable orthopedic positioning needle. Background In operations such as orthopedics trauma, backbone, joint, etc., orthopedics locating needle is an important instrument in the operation process, and it both can regard as the internal fixation consumptive material to implant the human body also can regard as the auxiliary instrument of other internal fixation consumptive materials, and the centre gripping is on electric tool to orthopedics locating needle when using, beats orthopedics locating needle in the bone through electric tool's high-speed rotation and doctor initiative thrust. The orthopedic positioning needle is often applied to an operation requiring installation of a hollow bone screw, the orthopedic positioning needle is required to be driven into bone at a position where the hollow screw is to be installed during the operation, if the positioning needle does not penetrate the contralateral cortical bone, the positioning needle is not required to be pulled out, only the depth of the positioning needle into the bone is required to be measured by using an integrated depth finder so as to select the hollow screw with a proper length, and if the positioning needle penetrates the contralateral cortical bone, the positioning needle is required to be pulled out, and the depth of the positioning needle into the bone is required to be measured by using a combined depth finder. The prior art has the following defects in the using process: 1. In the prior art, when the depth is measured by using the combined depth finder, the positioning needle needs to be pulled out, the friction force between the positioning needle and the bone is reduced and fixed infirm after the positioning needle is inserted after the depth is measured, and the positioning needle is easy to slide down after other operations are carried out; 2. in the prior art, the depth is measured by using a combined depth finder, a small hook in front of a probe of the depth finder is required to hook the contralateral cortical bone to obtain the accurate depth, and the small hook is difficult to design in a larger size due to size limitation, so that the contralateral cortical bone can not be hooked for measurement in actual use, and time is wasted; 3. The combined depth finder in the prior art has the advantages of complex structure, more parts and high processing cost; 4. In the prior art, the surgical instrument bag is also required to be provided with the depth finder independently under the condition of being provided with the positioning needle, so that the instruments are numerous, the surgical steps are complex, and the cost is increased. In view of the above, we propose a depth-measurable orthopedic positioning needle to solve the existing problems. Disclosure of utility model The utility model aims to provide a depth-measurable orthopaedics positioning needle so as to solve the problems in the background technology.
