Problems solved by technology

This device is too simple and will encounter many inconveniences in use
The utility model with the patent number of 200920091668.6 provides a fixed suspension structure, which cannot adapt to the dynamic changes of doctors during operation
The common disadvantages of the above-mentioned existing technologies are that they emphasize static weight loss, and do not consider the dynamic weight loss needs of doctors during operation.

example 1

[0016] Such as figure 1 Shown, the present invention is made up of main frame, weight measurement mechanism and weight control mechanism.

[0017] The top of the main frame is a cantilever beam 1, the head end of the cantilever beam 1 is provided with a suspension ring, and the tail end is vertically connected with the lifting shaft 4. Below the lifting shaft 4 is a column 17, on which a linear module 11 is installed; the top of the linear module 11 is equipped with a bearing frame 6 and a linear bearing 7; the bottom of the lifting shaft 4 is installed in the linear bearing 7, and the linear The module 11 is slidingly fitted, and the bottom end of the lifting shaft 4 is connected with the slide bar 9 in the linear module 11 , and the bottom end of the slide bar 9 is installed on the slide bar seat 10 in the linear module 11 . The bottom end of the linear module 11 is connected with a stepper motor 13 through a coupling 12 . The stepper motor 13 drives the slide bar 9 and th...

example 2

[0021] This example is the operating principle of the present invention.

[0022] The weight measurement and control system of the present invention is actually a follow-up device with constant pulling force. The set pulling force of the device to the lead suit 5 is about the weight of the lead suit 5. In order to keep this pulling force constant, the height of the slide bar 9 is obviously Should be fixed. When lead clothing 5 moves up and down along with doctor's working position, the height of slide bar 9 also should be changed thereupon, otherwise, this device will lose balance to the pulling force of lead clothing 5. At this moment, the effect of the tension sensor 3 and the measurement and control circuit board 14 is to design the rising or falling height that the slide bar 9 should make in order to cooperate with the change of the doctor's body position.

[0023] The working principle of the present invention is: the electric signal value of the weight of the lifting pr...

Abstract

The invention discloses a lead clothes weight control mechanism, which consists of a main body frame and a weight measurement and control system. The main body frame comprises a slide rod with a cantilever beam, the lower section of the slide rod is mounted in a linear module via a bearing rack and a linear bearing, the bottom end of the linear module is fixed at the top of a semi-annular base, and universal wheels are mounted under the base. The lower end of a control wire is fixed at the bottom of the linear module while the upper end of the control wire is sleeved on a hanging wire of the head end of a crossbeam. A weight measurement mechanism comprises a weight reduction tension spring and a tension sensor, the upper end of the weight reduction tension spring is tied on the control wire, the tension sensor is hung at the bottom of the weight reduction tension spring, a lead clothes hanging hook is mounted at the bottom end of the tension sensor, and a weight control mechanism comprises a measurement and control circuit board connected with a stepping motor. The lead clothes weight control mechanism has the advantages that the lead clothes weight control mechanism is simple in structure and convenient in operation, the semi-annular base with the universal wheels brings convenience for doctors to walk, most of the weight of lead clothes can be loaded by the weight measurement and control system, when the body position of a doctor is changed, the lead clothes weight control mechanism also can track the doctor, and constant tension is kept.

Description

technical field [0001] The invention relates to a lead suit weight control mechanism. Background technique [0002] In the hospital sector, doctors have many medical operations that need to be performed under X-rays, especially in recent years, the use of minimally invasive interventional therapy instead of traditional surgery to treat diseases such as heart disease, cerebrovascular disease, and gallbladder has become more and more popular. Because this operation is carried out under the supervision of X-rays, in order to prevent damage, doctors must wear heavy lead clothing during operation to reduce the radiation of X-rays to the human body. Because the radiation protection effect of lead clothing is related to the lead content, and the lead content is related to the weight, so the general lead clothing is very heavy. Doctors not only have to bear the pressure brought by the operation, but also bear the gravity brought by wearing lead suits for a long time. The doctors ar...
