[0031] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.
[0032] The release damper device of the utility model comprises a special-shaped pointed head, a damping member, an operating rod, an advance and retreat handle and a rotation fixer. The device also comprises a flat plate, a left fixed leg and a right fixed leg. The fixed leg and the right fixed leg are respectively fixed on the left and right sides of the flat plate. The special-shaped pointed head has left and right channels. The left fixed leg of the rotation fixer is inserted into the left channel so that the left fixed leg is fixed to the left channel, and the right fixed leg is inserted into the right channel. The operating rod is connected to the right fixed leg, and the advance and retreat handle is connected to the operating rod. The rotation fixer is fixed on the working channel opening of the endoscope, and the device is fixed on the special-shaped pointed head. The advance and retreat handle is used to control the operating rod.
[0033] As a preferred embodiment of the present invention, the connection between the left and right fixed legs of the rotating fixture and the flat plate is a thin plastic structure, and the thin plastic structure supports left and right swinging of bending deformation.
[0034] As a preferred embodiment of the utility model, the upper part of the left fixed leg is a cross-shaped structure, which divides the left channel into four spaces, and the four spaces are used for ventilation, liquid perfusion or suction.
[0035] As a preferred embodiment of the present utility model, the advance and retreat handle is provided with a scale mark.
[0036] As a preferred embodiment of the utility model, the operating rod supports lifting and lowering with a controllable distance within a scale range when the damper is detached.
[0037] As a preferred embodiment of the utility model, the left channel of the special-shaped pointed head is used for releasing lubricating water or cleaning and disinfecting the cavity, and the right channel is used for releasing the damping device.
[0038] As a preferred embodiment of the utility model, the operating rod supports the extension of the working channel opening of the endoscope handle, and the operating rod and the working channel opening are locked by rotating the fixture, and the scale marking of the operating rod is exposed to the outside.
[0039] As a preferred embodiment of the utility model, after the endoscope finds the position where the stent needs to be released and injects hot water to combine with the stent to expand, the operating rod is rotated to release and pushed forward, and the damper is pushed forward.
[0040] The utility model involves an incision-type dual-channel tip device, which is designed to fully utilize the visualization of the endoscope to accurately position and control the entry into the cavity, and combined with the modified design on the tip of the endoscope, to achieve the intended purpose of use.
[0041] This utility model is designed to achieve a new purpose of positioning and releasing the urethral stent based on the visualization and precise positioning and control of the endoscope. On the basis of the dual channels of the endoscope, one working channel is used to place and release the damping device, and one channel is used for lubricating water before releasing the damper, or for the cleaning and disinfection cycle of the cavity. The damper is cleverly fixed on the pointed head with an anisotropic incision to prevent the stent from entering the cavity due to inaccurate positioning or reduce the risk of failure in releasing the stent. It is indeed a good utility model design.
[0042] In a specific embodiment of the utility model, it relates to a damping device for fixing a release bracket on a pointed tip, comprising a matching special-shaped pointed tip, a damping member that can be prevented and detached, an operating rod with an extension scale at the rear end for controlling the damping member to fall off, an advance and retreat handle for controlling the operating rod, and a rotating fixture on the opening of an endoscope working channel.
[0043] The release bracket damper includes a fixed special-shaped tip, a damping member that can be blocked and removed, an operating rod connected to the damping member that can be blocked and removed, a forward and backward handle for operating the operating rod with a scale mark, and a rotating fixture fixed to the endoscope working channel. The damping member is a small structure in the damper. The operating rod is connected to the right fixed leg.
[0044] The damper is an injection-molded part that can withstand water temperatures of 55 degrees without deformation.
[0045] The damper fixed on the special-shaped pointed head is an irregular object, which is raised and lowered by an operating rod at a controlled distance within a scale range when being removed.
[0046] After the rotatable structural part is inserted into a working channel of the tip, the contact part forms a fixing effect.
[0047] The other part of the damper is fixed to the second working channel and is also inserted into the working channel with a release operating rod.
[0048] The damper of the device is used to fix the bracket and release the bracket. The damper has multiple rotatable structures for fixing and releasing the bracket, and is operated from the outside through a connecting mechanism. At the same time, it has a blocking mechanism for the working channel, which can control the flow direction of water injected into the working channel of the tip from the outside.
[0049] The fixed bracket on the left is a cross-shaped structure. When it is inserted into the left channel and fixed, it does not completely block the channel, but only divides the channel outlet part (equivalent to the length of the fixed bracket) into four spaces. The part divided into four spaces can still be used as a channel to release lubricating water or clean and disinfect the cavity.
[0050] The connection between the bracket and the plate is a very thin plastic structure. Due to the toughness of plastic, the thin plastic wall can bend and deform and swing left and right without breaking, which is equivalent to the effect of a rotating shaft.
[0051] The damper structure can be used as a baffle, because the damper is designed to be placed right in front of the two channels, and when liquid is injected into the channels, the baffle can block the direct injection of liquid from the channel outlets.
[0052] The bracket is in the shape of a spring structure. When it comes into contact with hot water, the diameter of the front end part increases and the axial length changes slightly, but not significantly.
[0053] After the operating rod of the damper is extended out of the working channel opening of the endoscope handle, the operating rod and the working channel opening are locked by rotating the fixing device. This prevents the operating rod from loosening and affecting the fixing of the damper at the front end. The scale mark of the operating rod is exposed on the outside. Figure 4 As shown in the figure, the front end shows the damper in the open state, and the rear end shows the operating rod being pushed in, with only one scale left on the scale. Figure 5 As shown, the front end is the damper in the unopened state, the rear end is the operating lever in the original state, and the schematic scale shows three scales.
[0054] When the endoscope with the stent enters the human body cavity and finds the position where the stent needs to be released, 55-degree hot water is injected into the outer sheath injection port of the endoscope insertion tube. When the hot water combines with the stent and expands, the operating lever is rotated to release it and pushed forward. At this time, the other end of the damper is rotated due to its fixation, and the damper is partially pushed forward.
[0055] After the damper is pushed out by the operating rod and tilted, the endoscope and the outer sheath of the endoscope insertion tube are withdrawn at the same time. After the stent with the front end expanded by hot water is fixed to the body cavity, the damper has an outer diameter smaller than the endoscope of the stent, so the endoscope can be smoothly withdrawn from the body cavity, completing the process of releasing the stent. Among them, the diameter of the damper is smaller than that of the stent after expansion. After the stent is exposed to hot water, the diameter will increase and the length will change slightly, but the change in length will not affect the withdrawal of the damper. The diameter of the damper is larger than that of the stent before expansion, and smaller than that of the stent after expansion.
