Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a rotary mechanism of a gastroenteric DR bull head cross arm which is convenient for disassembly and maintenance. Background Art

[0002] Digital gastrointestinal DR is an X-ray examination device used to examine gastrointestinal diseases. Its core function is to perform contrast diagnosis on various diseases of the pharynx, esophagus, stomach, duodenum, jejunum and ileum, and colon. It is one of the main examination methods for examining various ulcers, tumors, foreign bodies and other diseases. At the same time, digital gastrointestinal DR also has a fluoroscopy function and supports the operation of some vascular and non-vascular interventional therapies. Digital gastrointestinal DR makes the traditional gastrointestinal examination convenient and fast. During the examination process, patient information can be digitally stored, played back and imaged. Its advantages are that it does not require anesthesia and intubation, reduces the discomfort of patients, and can comprehensively observe the gastric structure, which is convenient for initially and efficiently identifying the nature of lesions.

[0003] In the existing digital gastrointestinal DR, the treatment bed is usually rotated and adjusted to meet the shooting requirements at multiple angles. However, there may be shooting dead angles due to angle limitations in some specific examination areas, resulting in incomplete image acquisition, which in turn affects the comprehensiveness and accuracy of contrast diagnosis. Moreover, limited by the structure of the existing gastrointestinal DR, it cannot achieve the bull head rotation function, which to a certain extent limits the flexibility during the use of the gastrointestinal DR and the comprehensiveness of the shooting angle, and it is also difficult to form a good contrast imaging effect.

[0023] The inventor found through the analysis of the prior art that: the digital gastroenterology DR of the prior art cannot achieve the bull head slewing function during use. In specific examination areas, due to the inability to flexibly adjust the shooting angle, there are shooting dead angles, resulting in incomplete acquisition of image information and affecting the comprehensiveness and accuracy of contrast diagnosis, thus making it difficult to provide more reliable and accurate medical image support for clinical practice. In this case, a device that can make the gastroenterology DR bull head rotate in all directions has become a new demand.

[0024] Refer to Figure 1 , which shows a schematic structural diagram of a slewing mechanism of a gastroenterology DR bull head cross arm that is convenient for disassembly and maintenance of the utility model.

Based on the existing gastrointestinal machine, the present application provides a rotary mechanism for the bull's head cross arm of a gastrointestinal DR that is convenient for disassembly and maintenance, enabling all-round rotation control of the bull's head during the diagnosis using the gastrointestinal DR, so as to flexibly adjust the shooting angle, ensure that all shooting dead angles are covered without omission, thereby improving the comprehensiveness and accuracy of the diagnosis. Moreover, when maintenance or repair is required, only some components of the rotary mechanism need to be simply disassembled, facilitating subsequent equipment maintenance work.

[0026] Next, a rotary mechanism for the bull's head cross arm of a gastrointestinal DR that is convenient for disassembly and maintenance in this exemplary embodiment will be further described.

[0027] It should be noted that the X-ray tube assembly 1, the X-ray tube connecting plate 2, the support seat 3, the driving device 4, and the coupling 5 are arranged in a straight line. When an angle adjustment is required, the driving device 4 is powered on, and the driving device 4 drives the rotation through the coupling 5. The coupling 5 transmits the power to the X-ray tube assembly 1 through the support seat 3 and the X-ray tube connecting plate 2, driving the X-ray tube assembly 1 to rotate coaxially, thereby completing the overall rotation of the rotary mechanism.

[0028] In an embodiment of the present application, the driving device 4 includes a motor 6 and a speed reducer 7; the motor 6 and the speed reducer 7 are connected in cooperation.

[0029] It should be noted that the motor 6 and the speed reducer 7 can be connected in cooperation by means of direct connection or a coupling 5, etc.; when the motor 6 is started, the speed reducer 7 plays a role in reducing speed and increasing the output torque.

[0030] In an embodiment of the present application, the motor 6 and the speed reducer 7 are integrally and detachably installed on the support seat 3.

[0031] It should be noted that the speed reducer 7 is fixed on the support base 3 by a plurality of screws, and the motor 6 is not directly connected to the support base 3. When it is necessary to install or disassemble the driving device 4, only the two need to be disassembled as a whole, and the operation is simple; further, the projections of the motor 6 and the support frame 3 during operation do not overlap each other, and it is also convenient and fast when only the motor 6 needs to be installed or disassembled.

[0032] In an embodiment of the present application, the speed reducer 7 and the support base 3 are respectively provided with a connecting shaft (not shown in the figure) connected to the coupling 5.

[0033] It should be noted that the speed reducer 7 and the support base 3 are connected by the connecting shaft and the coupling 5 to achieve reliable transmission of motion and torque.

[0034] In an embodiment of the present application, the support base 3 is of a U-shaped structure.

[0035] It should be noted that the support base 3 is of a U-shaped structure, with a hollow part formed in the middle. The driving device 4 is installed in the hollow part formed by the support base 3, and the speed reducer 7 is fixedly connected to both sides of the support base 3 respectively, so that both sides are evenly stressed during rotation.

[0036] In an embodiment of the present application, the tube assembly 1 includes a tube, a tube clamp and a collimator 10; the tube clamp is sleeved on the tube; the collimator 10 is arranged on the side of the tube.

[0037] It should be noted that the tube is used to generate X-rays, the collimator 10 is used to control the radiation range and direction of the X-rays, and the X-rays generated by the tube pass through the collimator 10 and then irradiate the part to be detected, so as to improve the image quality and reduce the radiation dose.

[0038] In an embodiment of the present application, the support base 3 is fixedly installed with an encoder 11; the encoder 11 is connected with a gear disk 12; a transmission gear 13 matching with the gear disk 12 is arranged between the coupling 5 and the driving device 4.

[0039] It should be noted that the driving device 4 drives the transmission gear 13 to transmit power, the transmission gear 13 meshes with the gear disk 12, and the encoder 11 can record the movement of the slewing mechanism and measure the rotation angle of the slewing mechanism.

[0040] In an embodiment of the present application, the rotation angle of the slewing mechanism is 360°.

[0041] It should be noted that the slewing mechanism can realize omnidirectional free rotation to achieve multi-angle imaging.

[0042] In one embodiment of the present application, it further includes a slewing limit device 14 for limiting the rotation angle of the slewing mechanism.

[0043] It should be noted that the slewing limit device 14 can achieve the mechanical limit of the slewing mechanism of the bull cross arm, thereby playing a role in rotating mechanical protection.

[0044] In one embodiment of the present application, the slewing limit device 14 is arranged between the support base 3 and the tube connecting plate 2.

[0045] It should be noted that when the driving device 4 is started, the support base 3 and the tube connecting plate 2 rotate, and the 360-degree rotation of the slewing mechanism is limited by the slewing limit device 14 installed between the two.
