Mammary machine compression device

Abstract

The invention discloses a mammary machine compression device, which comprises a compression panel, a guide rail, a sliding block base and a compression bracket, and further comprises a first transmission device, a driving device, a brake, a manual unlocking device and a damper, wherein the sliding block base is arranged on the guide rail and is capable of moving up and down along the guide rail; the compression bracket is fixedly connected to the sliding block base; the first transmission device comprises a first belt wheel, a second belt wheel and a first synchronous belt; the first belt wheel is connected to the second belt wheel by virtue of the first synchronous belt; the first synchronous belt is contacted with the sliding block base and is capable of driving the sliding block base to move up and down; the driving device is connected to the first belt wheel; the brake is connected to the driving device and is used for braking the driving device in the case of power failure; the manual unlocking device is arranged on the compression bracket; and the damper is arranged on the manual unlocking device. The compression device disclosed by the invention is higher in transmission precision and is safer and reliable, and the compression device is capable of effectively reducing cost and reducing weight; in the case of power failure, the manual unlocking device is capable of releasing compression force, so as to avoid compression injury on patients; and the compression device is simple and convenient to operate, and is capable of meeting needs of clinical application.

Description

technical field [0001] The invention relates to the field of mammary gland X-ray machines, in particular to a mammary gland compression device. Background technique [0002] Breast machine compression device plays a very important role in mammography X-ray examination, and its design is related to the image quality obtained. [0003] The mammary gland compression device generally uses electric power to drive the compressor to perform linear motion, and the transmission methods used include gear transmission, chain transmission, etc. Most of the compression devices on the market have an unlocking function, and the unlocking mechanism generally includes a flip-type compression plate, electric drive, or manual adjustment of a two-way backstop. [0004] Although the use of gear transmission or chain transmission can obtain more precise transmission accuracy, it has a relatively large weight, and the structure of the whole system is also relatively complicated, which will inevit...

Problems solved by technology

[0004] Although the use of gear transmission or chain transmission can obtain more precise transmission accuracy, it has a large weight and the structure of the whole system is also relatively complicated, which will inevitably increase the burden on the main shaft rotation drive device

In addition, although the reversible compression plate can be manually unlocked when the power is cut off, it is cumbersome to operate, and skilled clinical operators need to be trained; the electric drive is driven by a pulse generator to unlock the drive device, and it needs to be equipped with a special battery to prevent When the power is off, it cannot be unlocked, which will cause damage to the user; the cost of the two-way backstop is relatively high, and it relies on wedge-shaped locking, so the reliability is poor
