The invention discloses a medical bone drill provided with an easy-to-clean steel wire soft spring. The medical bone drill comprises a quick connector, the steel wire soft spring, a soft spring sleeve, a connector and a drill bit, wherein the quick connector sequentially comprises a connector top rod, an assembly rod and a connector bottom rod from top to bottom; the connector comprises an upper connector and a lower connector; the drill bit comprises a drill rod, a drill body and a drill point; one end of the steel wire soft spring is connected with the connector bottom rod by means of the soft spring sleeve, and the other end of the steel wire soft spring is connected with the upper connector by means of the soft spring sleeve; the lower connector is connected with the drill rod. Due tothe arrangement of the steel wire soft spring and the soft spring sleeve, scraps can not easily enter from the two ends of the steel wire soft spring, and the steel wire soft spring is further conveniently cleaned; by controlling an angle between the steel wire soft spring and the drill bit, the medical bone drill can be used for drilling at a narrow place or a place with a limited space.
Description
technical field [0001] The invention relates to the field of orthopedic medical instruments, in particular to a medical bone drill for cleaning steel wire soft springs. Background technique [0002] In surgical operations, doctors often need to drill holes in human bones, and doctors usually use power devices to drive bone drills to drill holes. The drilling direction of the existing bone drill cannot be changed, or when the space is relatively narrow or limited, it is not easy to perform the drilling operation; in addition, there will be bone chips and other debris entering the bone drill during the drilling, not easy to clean [0003] Therefore, the applicant proposes a bone drill capable of drilling in a limited space and easily cleaning the inside. Contents of the invention [0004] The object of the present invention is to provide a medical bone drill which is convenient for cleaning the soft spring of steel wire, so as to solve the problems in the prior art.
