An orthopedic drill bit with adjustable drilling depth
By setting an adjustment slot and adjustment components in the orthopedic drill bit, the linear displacement of the limiting sleeve is achieved, which solves the problem of inaccurate depth control of traditional orthopedic drill bits, significantly reduces the risk of over-drilling or under-drilling, and improves the safety and stability of the operation.

AI Technical Summary
Technical Problem
Traditional orthopedic drills rely on the operator's experience to control the drilling depth, which can lead to over-drilling or under-drilling risks, and may cause complications such as cortical bone penetration, nerve and blood vessel damage, or implant loosening.
Method used
An orthopedic drill bit with adjustable drilling depth was designed. By setting an adjustment slot and adjustment component on the drill bit body, the limiting sleeve moves linearly along the drill bit axis. Combined with scale marks and limiting structure, the drilling depth can be precisely controlled.
Benefits of technology
This allows for precise control of drilling depth, reducing the risk of cortical bone penetration or insufficient internal fixation stability, and improving surgical safety.

Abstract
The utility model discloses an orthopedics drill bit of adjustable drilling depth, including drill bit body, be provided with the mounting rod on the drill bit body, be provided with the adjustment through groove on the mounting rod, be provided with the adjustment assembly in the adjustment through groove, the outer wall of drill bit body is equipped with the limit sleeve, the limit sleeve is connected with the adjustment assembly, the limit sleeve is driven along the drill bit body axle center reciprocating displacement, and the position of adjustment limit sleeve on drill bit body, the utility model has the advantage that: through setting the cooperation structure of adjustment through groove and adjustment assembly, makes limit sleeve linear displacement along drill bit body axle center, and the operator can set the interval between limit sleeve and drill bit body drill tip according to clinical demand in advance, thereby accurately limiting drilling depth, and the structure effectively solves the problem of over drilling or under drilling of traditional orthopedics drill bit due to the lack of depth limit, and the surgical risk of bone cortex penetration or internal fixation stability deficiency is reduced significantly.
