[0024] like Figures 1-4 The present invention provides a disposable gallbladder visualization rigid catheter, including a handle 1 and a scope body 2 connected to one end of the handle 1. The handle 1 includes a hand-held section 3 and a front section 4. The scope body 2 is connected to the front section 3. A tip seat 5 is provided at the end of the scope body 2 away from the handle 1. The tip seat 5 is used to place a camera and a light source. A photo button 6 is provided on the side of the hand-held section 3 near the front section 4, and the photo button 6 is communicatively connected to the camera.
[0025] The operator holds the handpiece of the disposable rigid gallbladder catheter, accurately controlling the orientation of the handle towards the endoscope. The catheter is then inserted into the gallbladder cavity through the puncture needle channel to observe for gallstones, polyps, or tumors. Direct visualization allows for the diagnosis of benign and malignant gallbladder diseases, avoiding the limitations and misdiagnosis rates of examinations such as ultrasound.
[0026] Meanwhile, since the photo button is connected to the camera, medical staff can take photos in real time by pressing the photo button, which improves the convenience of controlling the camera. There is no need to hold the handle with one hand and control the camera with the other, which can help the surgeon to operate with one hand and free up the other hand to perform other diagnostic and treatment operations.
[0027] The lens body is made of stainless steel capillary tube; the camera is a CMOS camera; the illumination is provided by a beam guide; and the CMOS camera is either TA10 or OVM6946.
[0028] In one embodiment of this solution, a cholangioscope bone can be provided at the end of the endpiece away from the front section of the handle, and the tip seat is installed at the end of the bone. At this time, a control lever is rotatably provided at the head end of the handpiece. The control lever is used to control the bending and turning of the bone. Since the control lever is located between the handpiece and the front section of the handle, the thumb can be placed on the control lever to accurately adjust the bending of the bone. The control structure and method of the bone are existing technologies and will not be described in detail here.
[0029] Preferably, the tip seat 5 is connected to the end of the mirror body 2, and the tip seat 5 is provided with a camera hole 7 and an illumination hole 8, so that the camera is placed in the camera hole 7 and the illumination is placed in the illumination hole 8.
[0030] Specifically, the camera and lighting are respectively fixed and limited by the camera hole and the lighting hole, which improves the stability of use during the operation and prevents the camera or lighting from falling off the tip seat.
[0031] The tip and the lens body are connected by adhesive, and the shutter button can communicate with the camera via wired or wireless means.
[0032] In one embodiment of this solution, at least two illumination holes 8 are provided at the tip seat 5, and the at least two illumination holes 8 are located on both sides of the camera hole 7, thereby ensuring that both sides of the camera have illumination sources and improving the clarity of the camera's shooting.
[0033] Preferably, there is a corner structure 9 between the handheld section 3 and the front section 4 of the handle, and the corner structure 9 adopts a 75°-85° angle.
[0034] Specifically, when the surgeon holds the handle, the handle is held vertically when the hand is raised. The corner structure makes the front of the handle horizontal, which in turn makes the scope horizontal, ensuring that the scope can be smoothly inserted into the gallbladder cavity.
[0035] It is worth mentioning that, since the hand does not remain completely vertical when it is raised normally, but is tilted to a certain degree relative to the vertical position, in order to ensure the stability of the scope and the comfort of the hand angle, this solution sets the corner structure to 75°-85°. Compared with a 90° right angle, this angle is more in line with the normal use state of the human hand, which can help improve the comfort of holding the handle for a long time during the operation.
[0036] Preferably, the hand-held segment 3 has a raised structure 10 on the side opposite to the corner structure 9 so that the raised structure 10 matches the center of the palm.
[0037] Specifically, when holding the handle, the raised structure can support the center of the palm, preventing the center of the palm from being loosely gripped. This is beneficial for comfort during long-term use and avoids unstable force caused by prolonged loose gripping, which can lead to hand soreness or instability of the lens.
[0038] It is worth mentioning that the overall handle is shaped like a "woodpecker" through the combined use of the hand grip section, the front section of the handle, the corner structure, and the protruding structure, which can effectively provide stability to the lens body.
[0039] Preferably, an arc-shaped groove 11 is provided between the front part 4 of the handle and the shutter button 6 so that the index finger can be placed in the arc-shaped groove 11.
[0040] Specifically, the curved groove design allows the index finger to rest stably on it. When the shutter button is not in use, the curved groove supports the index finger, preventing it from becoming sore or swollen from prolonged pressure and also preventing accidental presses of the shutter button.
[0041] Preferably, the end of the handheld section 3 away from the front section 4 of the handle is inclined to the side away from the lens body 2, and the end of the handheld section 3 away from the front section 4 of the handle has an opening, so that the tube 12 passes through the handheld section 3 and the front section 4 of the handle in sequence from the opening and enters the inside of the lens body 2.
[0042] Specifically, the tubing is connected to the inside of the endoscope through the opening, allowing the camera and lighting at the tip to be connected to the tubing to ensure the stability of the camera and lighting. At the same time, because the end of the handpiece away from the handle is tilted away from the endoscope, the tubing extends away from the endoscope as it extends outward from the opening, ensuring that the tubing does not affect the side of the endoscope and improving stability during the operation.
[0043] Pipelines refer to various types of lines such as cables and wires.
[0044] Preferably, the end of the hand-held section 3 away from the front section 4 of the handle has a protruding arc-shaped transition section 13 between it and the corner structure 9, so that the fingers can be placed at the arc-shaped transition section 13.
[0045] Specifically, when holding the handle, the index finger is placed in the curved groove and the palm is on the raised structure. At this time, the other fingers can be gripped in the curved transition section, so that the other fingers fit against the outside of the hand grip section, increasing grip stability and comfort.
[0046] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
