Description

Capsule endoscope PCB fixing support, fixing method and endoscope capsule

Technical Field

The invention relates to a medical apparatus, in particular to a fixing bracket and a fixing method for a wireless capsule endoscope PCB.

Background

The wireless capsule endoscope is widely applied to the aspect of examining digestive tract diseases of patients, and the structure of the wireless capsule endoscope is that an image acquisition module, a signal processing module, a battery, a radio frequency module and an antenna are integrated into a capsule core through a bracket and then are installed in a capsule shell, for example, the wireless capsule endoscope disclosed in CN 208659309U. As a simple assembling mode, electronic components such as the image acquisition module, the signal processing module and the radio frequency module are arranged on at least two PCBs, and the PCBs are connected through flexible parts such as FPC. The battery is arranged between the two PCBs through the spring and provides power for the PCBs.

However, in the existing assembly structure, the power supply of the PCB is poor due to the failure of the spring or the insufficient preset elastic force, or the assembly is wrong, so that the capsule is not used, but the battery is not charged. More importantly, as the FPC is made of soft material, the FPC needs to be carefully prevented from being squeezed or twisted during the assembly process, which causes poor contact or short circuit and disconnection, and thus causes extremely low production efficiency.

On the other hand, an adhesive will be used during assembly, thereby complicating the assembly process and further reducing production efficiency.

Those skilled in the art have therefore endeavored to develop an apparatus and method for more easily assembling a PCB board into a capsule shell.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

a capsule endoscope PCB fixing method, the PCB includes the first PCB 300 and the second PCB 400 connected by the flexible component FPC 200; the method comprises the following steps:

2) a battery 5 is arranged in the fixed bracket; both end surfaces of the battery are provided with springs 6;

As shown in fig. 1 to 5, the above method is implemented by a capsule endoscope PCB fixing bracket, which includes a cylindrical body 100, an X-direction gear and a Y-direction gear 110 are provided at one end of the body 100, and a first Z-direction gear 108 is integrally provided at the Y-direction gear of the end.

In other specific embodiments, the first Z-direction gear can be set on the X-direction gear to achieve substantially the same technical effect.

When the PBC is installed on the support, the FPC (flexible) can be bent in the Z-axis direction and the diameter direction, and in order to protect the FPC from being broken or cracked, avoidance notches 7 are formed in the two ends of the body 100 along the Z direction. The avoiding gap 7 is in a trapezoidal shape, and the opening close to the end part is larger than the opening close to the waist part. If the maintenance is needed to be disassembled, the operation is convenient and fast.

The X-direction gears at one end of the body 100 include a first X-direction gear 101, a second X-direction gear 102, and a third X-direction gear 103. The first X-direction gear 101 and the second X-direction gear 102 are located on both sides of the avoidance gap 7; the third X-direction gear 103 is located on the other side of the opposing escape notch 7.

The Z-direction height of the third X-direction gear 103 is greater than the Z-direction heights of the first X-direction gear 101 and the second X-direction gear 102.

The other end of the body 100 is provided with a fourth X-direction gear 104, a fifth X-direction gear 105, a sixth X-direction gear 106, and a seventh X-direction gear 107. The fourth X-direction gear 104 and the fifth X-direction gear 105 are located on both sides of the avoidance gap 7; the sixth X-range 106 and the seventh X-range 107 are located on the other side of the relative escape notch 7. A second Z-direction shift 109 is integrally provided in the X-direction shift of this end. The other end can be fixed left and right in the X direction and the Z direction, the Y direction can be omitted, but in order to fix the other end more firmly, a Y-direction gear can be arranged to achieve the required effect.

Because the Z-direction gear is of a barb structure, when the PCB is clamped downwards, in order to prevent the first Z-direction gear from being deformed or broken, abdicating notches 4 are arranged on two sides of the Y-direction gear.

The outer surface of the body 100 is provided with a fool-proof rib 8 along the Z direction. Therefore, after the capsule core is placed in the capsule shell, the capsule core cannot rotate, and once the capsule core rotates, the capsule performance can be affected due to the power failure.

Obviously, as shown in fig. 6, the capsule endoscope using the fixing bracket can increase reliability, improve production efficiency and reduce production cost.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
