Medical electric saw

Abstract

The invention discloses a medical electric saw mainly comprising a round saw blade, a drive unit driving the saw blade to rotate, and a housing containing the saw blade and the drive unit; the front portion of the housing is a saw blade cover, and a rear portion is a handle portion; the saw blade cover is a semicircle cavity, and an inner arc surface of the cavity is provided with a narrow and long through hole; the electric saw also comprises a saw blade positioning device; the saw blade positioning device comprises a push rod with one end inserting into the cavity and a depth adjusting element used for controlling the insertion depth of the push rod into the annular cavity; the push rod is made of elastic material, and can bend to an radian level matched with the inner side of the cavity; the center of the saw blade is coaxially fixed with a drive shaft; the drive shaft is rotatably and axially fixed on the end of the push rod; certain part of the saw blade extends outside the through hole. The medical electric saw can improve safety of the saw blade, and can complete osteodiastasis operation works in a narrow space in one time.

Description

technical field [0001] The invention relates to an orthopedic surgical tool, in particular to a medical electric saw. Background technique [0002] The medical bone saw is a commonly used surgical instrument in orthopedic surgery. The disadvantages of the existing medical bone saw: 1) The safety of the saw blade is poor, and it is not possible to perform one-time bone separation in a relatively narrow space in the surgical environment. In order to increase the surgical space, it is necessary to Unnecessary cutting of the patient's muscles is required, and at the same time, it is necessary to cooperate with the muscle puller to pull the muscles, and the bone sawing work can be successfully completed under the condition of fully exposing the surgical field of view; 2) The function of the existing medical bone saw is relatively simple. It is easy to misalign left and right during the operation, causing mistakes and affecting the normal operation of the operation. Contents of ...
