Abstract

The invention discloses a medical vertical saw transmission mechanism. A medical vertical saw comprises a saw blade (33), and a main shaft (10) connected with the saw blade (33); the medical verticalsaw transmission mechanism comprises a poking fork (9), a mounting shell (34), and a transmission shaft (27), an eccentric shaft (16), a first gear (20) and a second gear (35) mounted in the mountingshell (34); one end of the poking fork (9) is connected with the main shaft (10), and an opening (9a) is formed in the other end of the poking fork (9); one end of the transmission shaft (27) is connected with a driving shaft, and the other end is connected with the first gear (20); one end of the eccentric shaft (16) is connected with the second gear (35), and the other end is arranged in the opening (9a); and the first and second gears (20, 35) are engaged with each other. Through gear transmission, power is transferred to the poking fork to drive the saw blade to perform a reciprocating motion, so that the manufacturing difficulty of the transmission mechanism is reduced, the cost is reduced, and the protection requirements are reduced; and the transmission mechanism can work under multiple working conditions to achieve high transmission efficiency and reliable use.

Description

technical field [0001] The invention relates to a transmission mechanism of a medical vertical saw. Background technique [0002] As a medical device for hospital surgery, the medical vertical saw has the advantages of beautiful appearance, small size, light weight, easy to carry, safe operation and shortened operation time. The existing transmission and guide mechanisms are generally lead screws, guide rails, etc., which have complex manufacturing processes, high cost, cannot realize self-locking, poor shock resistance, and have high requirements for protection. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned defects in the prior art, and provide a power transmission mechanism of a medical vertical saw, which has a stable transmission and a simple structure. [0004] In order to achieve the purpose of the above invention, the present invention adopts the following technical solution: a transmission mechanism of a med...
