Description

Technical Field

[0001] The utility model relates to the field of electronic endoscope design, in particular to an easy-to-operate electronic endoscope. Background Art

[0002] Endoscopes are common medical devices that allow doctors to observe internal structures and assess pathological tissues, leading to better diagnosis and treatment. Common endoscopes include fiberscopes and electronic endoscopes. Compared to fiberscopes, electronic endoscopes have higher imaging resolution.

[0003] In common electronic endoscopes, the portion connected to the camera fiber is often located above the portion connected to the operating tube. The portion connected to the camera fiber is larger than the portion connected to the operating tube. The portion connected to the camera fiber may block the portion connected to the operating tube, affecting the user's operation.

[0004] If the user rotates the electronic endoscope so that the part connected to the operating tube faces upward, since common electronic endoscopes are different from fiber endoscopes, the scope of the electronic endoscope will become integrated after being connected to the camera fiber and is difficult to adjust independently. Therefore, after the scope body is rotated, the image it captures will rotate synchronously, affecting observation and easily misleading subsequent user operations. Utility Model Content

[0005] The purpose of the present utility model is to provide an easy-to-operate electronic endoscope that can solve one or more of the above problems.

[0006] According to one aspect of the present invention, an easy-to-operate electronic endoscope is provided, comprising an endoscope body, an insertion tube, a scope holding ring, a camera connection mechanism, and an operation connection mechanism.

[0011] In some embodiments, the camera connection mechanism includes a sealing cover that is detachably mounted on the other end of the lens housing. The sealing cover can seal the connection position with the camera fiber when the camera connection mechanism is not connected to the camera fiber to prevent it from being contaminated and damaged by the outside world.

[0012] In some embodiments, the protrusion is arranged obliquely to the endoscope body. In this arrangement, the protrusion can adapt to the user's grip and increase the contact area between the protrusion and the user's hand when gripping, thereby improving the grip reliability of the protrusion.

[0013] In some embodiments, the operational connection mechanism includes a connecting tube, a hard tube connector, and a soft tube connector. One end of the connecting tube is connected to the endoscope body, and the other end is connected to the hard tube connector. The soft tube connector is connected to the side of the connecting tube, and the soft tube connector is provided with a first valve seat. The hard tube connector facilitates connection to a hard tube such as a lithotomy forceps inlet tube, while the soft tube connector facilitates connection to a soft tube such as a catheter or optical fiber.

[0023] The operating connection mechanism 5 includes a connecting tube 51, a hard tube connector 52, and a soft tube connector 53. The other end of the endoscope body 1 is provided with a groove. One end of the connecting tube 51 is fixedly connected to the groove of the endoscope body 1 by threaded engagement, while the other end of the connecting tube 51 is fixedly connected to the hard tube connector 52 by threaded engagement. The side of the connecting tube 51 is obliquely convex, and the soft tube connector 53 is fixedly connected by threaded engagement and obliquely convex. The soft tube connector 53 is provided with a first valve seat 531.

[0024] The operating connection mechanism 5 also includes a water pipe connector 54, which can preferably be two. The two water pipe connectors 54 are fixedly connected to the connecting pipe 54 through threaded cooperation. After setting, the two water pipe connectors 54 are symmetrically arranged, and a second valve seat 541 is also provided on the water pipe connector 54.

[0025] The camera connection mechanism 4 includes a connecting sleeve 41, a lens sleeve 42, and a connector 43. A protrusion 11 is provided on the bottom side of the endoscope body 1. The protrusion 11 is arranged obliquely to the endoscope body 1. The protrusion 11 is fixedly sleeved on one end of the connecting sleeve 41 through a threaded fit, and one end of the lens sleeve 42 is fixedly sleeved on the other end of the connecting sleeve 41 through a threaded fit. The cross-section of the connecting portion between the connecting sleeve 41 and the lens sleeve 42 is larger than the connecting portion between the connecting sleeve 41 and the protrusion 11, so that the connecting sleeve 41 can play a certain light-guiding role. A sealing ring can be provided at the connection between the lens sleeve 42 and the connecting sleeve 41 to improve the sealing of the connection between them. The connector 43 is fixedly embedded in the lens sleeve 42. After connection, the camera connection mechanism 4 is arranged obliquely on the bottom side of the endoscope body 1.

[0026] The rear operation connection mechanism 5 is provided above the camera connection mechanism 4 .

[0027] The camera connection mechanism 4 can also include a sealing cover 44, which is detachably mounted on the other end of the lens case 42. After being set, the sealing cover 44 can close the end of the lens case 42 to seal the lens case 42, and a sealing ring can be provided on the sealing cover 44. After the sealing cover 44 and the lens case 42 are connected, the sealing ring can be set at the connection position to improve the sealing between them.

[0028] The bottom of the lens holding ring 3 is fixedly connected to the top side of the endoscope body 1 by welding, and the lens holding ring 3 is arranged perpendicular to the endoscope body 1. The side of the lens holding ring 3 is provided with a through hole allowing the user's fingers to pass through.

[0029] When the present invention is in use, the camera connection mechanism 4 can be connected to the camera optical fiber. Specifically, the sealing cover 44 can be removed from the lens sleeve 42 first, and then the lens sleeve 42 can be put on the camera optical fiber, and the camera optical fiber and the connector can be connected, and the camera optical fiber can be connected to an external imaging device to facilitate the display of subsequent images.

[0030] In addition, compared with traditional endoscopes, this endoscope can be regarded as an inverted setting of the traditional endoscope for the operating connection mechanism 5 and the camera connection mechanism 4, so that the external display device can pre-set the displayed image to be inverted from the image taken by the traditional endoscope, ensuring that the final display can conform to the user's observation habits.

[0031] For the operating connection mechanism 5, the external hard tube can be sleeved on the hard tube connector 52 so that the hard tube connector 52 is connected to the hard tube. In this embodiment, it is preferred that the hard tube connector 52 is connected to the lithotomy forceps input tube, and the lithotomy forceps input tube can be used for the insertion of the lithotomy forceps, and the external soft tube can be sleeved on the soft tube connector 53 so that the soft tube connector 53 is connected to the soft tube. In this embodiment, it is preferred that the soft tube connector 53 is connected to a catheter, and fluids such as medical solutions can be transported in the catheter, and a valve is connected to the first valve seat 531, which can control the flow rate of the fluid flowing into the connecting tube 51 through the soft tube connector 53.

[0032] The two external water pipes can be respectively mounted on the two water pipe connectors 54 so that the two water pipe connectors 54 are respectively connected to water pipes, and one water pipe can serve as a water outlet pipe and the other water pipe can serve as a water inlet pipe. The second valve seat 541 on the water pipe connector 54 can be respectively connected to a valve, which can be used to control the water flow through the water pipe connector 54.

[0033] After the insertion tube 2 is inserted into the patient's body, since it is connected to the camera fiber, the camera fiber can provide a certain amount of illumination light through the illumination fiber 23 of the insertion tube 2, and the image captured by the camera 24 can be output to an external imaging device through the camera fiber for display.

[0034] And when necessary, the user can use the water pipe connected to the water pipe connector 54 to allow water to enter and exit the patient's body through the instrument channel 221. The user can also use the soft tube connected to the soft tube connector 53 to transport fluids such as liquid medicine, and the fluid can enter the patient's body through the instrument channel 221. The user can also input lithotomy forceps through the hard tube so that a part of the lithotomy forceps extends through the instrument channel 221, so that the user can directly operate the lithotomy forceps inside the patient's body.

[0035] In the present invention, since the operating connection mechanism 5 is arranged above the camera connection mechanism 4, the camera connection mechanism 5 and the camera optical fiber connected thereto can avoid obstructing the doctor's medical operations when the present invention is in use, making it convenient for the doctor to perform operations such as water infusion and lithotomy without having to specially rotate the endoscope.

[0036] Since the size of the camera connection mechanism 4 is larger than the operating connection mechanism 5, this arrangement can better facilitate the user to hold the endoscope when using the endoscope. In addition, the present invention is also provided with a lens holding ring 3. When the user holds the present invention, the fingers other than the index finger can hold the camera connection mechanism 4, and the index finger can pass through the through hole on the lens holding ring 3, thereby effectively improving the user's grip reliability on the endoscope and reducing the probability of the endoscope accidentally falling.

[0037] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
