Description

Technical Field

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

[0002] Endoscope is a common medical device. It can help doctors observe the internal structure of the patient and evaluate the condition of the diseased tissue to better diagnose and treat the disease. Common endoscopes mainly include fiber endoscopes and electronic endoscopes. Compared with fiber endoscopes, electronic endoscopes have higher imaging resolution.

[0003] In common electronic endoscopes, the portion connected to the optical fiber for imaging is often located above the portion connected to the operating tube. The portion connected to the optical fiber for imaging is larger than the portion connected to the operating tube. The portion connected to the optical fiber for imaging may block the portion connected to the operating tube, thus 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 body of the electronic endoscope will become integrated after being connected to the camera optical 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. Summary of the invention

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

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

[0007] One end of the insertion tube is connected to one end of the endoscope body, the other end of the endoscope body is connected to the operating connection mechanism, the camera connection mechanism is connected to the bottom side of the endoscope body, the scope holding ring is connected to the top side of the endoscope body, and the operating connection mechanism is arranged above the camera connection mechanism.

[0008] The beneficial effects of the present invention are as follows: in the present invention, the camera connection mechanism can be used to connect the camera optical fiber, and the operating connection mechanism can be used to connect operating tubes such as water pipes or catheters. The operating connection mechanism is arranged above the camera connection mechanism, which can avoid the camera connection mechanism and the camera optical fiber connected thereto blocking the operating tube when the present invention is in use, and facilitates the doctor to perform water delivery, use lithotripsy and other operations without having to specially rotate the endoscope. Also, because the size of the camera connection mechanism is larger than that of the operating connection mechanism, this arrangement can also better facilitate the user to hold the endoscope when using the endoscope. A mirror holding ring is also provided, so that when the user holds the endoscope, the mirror holding ring can facilitate the user's finger insertion, improve the user's holding reliability of the endoscope, and reduce the probability of the endoscope accidentally falling. At the same time, the mirror holding ring can effectively remind the user of the swing direction of the present invention when in use, and avoid the user mistaking the endoscope for a conventional endoscope and using the endoscope upside down.

[0009] In some embodiments, the lens holding ring is arranged perpendicular to the endoscope body, and a through hole is arranged on the side of the lens holding ring. Under this arrangement, when the user holds the endoscope, the user's fingers can effectively pass through the through hole to better hold the endoscope.

The bottom side of the endoscope body is provided with a convex block, the convex block is sleeved on one end of the connection sleeve, one end of the lens sleeve is sleeved on the other end of the connection sleeve, and the connector is embedded in the lens sleeve. When the camera connection mechanism is connected to the camera optical fiber, the connector can be docked with the connector, and the lens sleeve can be sleeved on the camera optical fiber, thereby increasing the contact area with the camera optical fiber and improving the connection reliability with the camera optical fiber.

[0011] In some embodiments, the camera connection mechanism includes a sealing cover, which is detachably mounted on the other end of the lens sleeve. The sealing cover can seal the connection position with the camera optical fiber when the camera connection mechanism is not connected to the camera optical 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. Under 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 holding, thereby improving the grip reliability of the protrusion.

[0013] In some embodiments, the operation 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 can be easily connected to a hard tube such as a lithotomy forceps input tube, while the soft tube connector can be easily connected to a soft tube such as a catheter and an optical fiber, and the provision of the first valve seat can facilitate the installation of a valve, so as to control the flow rate of the fluid transported in the connected soft tube.

[0014] In some embodiments, the operation connection mechanism includes a water pipe connector, the water pipe connector is connected to the connecting pipe, and the water pipe connector is provided with a second valve seat. The water pipe connector can be used to connect to an external water pipe, so that when the present invention is used, water can be added to the user's body through the water pipe or part of the water in the user's body can be discharged, and the second valve seat can facilitate the installation of the valve, thereby facilitating the control of the water flow in the water pipe.

The camera 24 is fixedly embedded in the illumination optical fiber 23.

[0023] The operation connection mechanism 5 includes a connection tube 51, a hard tube connector 52 and a soft tube connector 53. A groove is provided at the other end of the endoscope body 1, one end of the connection tube 51 is fixedly connected to the groove of the end of the endoscope body 1 by threaded fit, and the other end of the connection tube 51 is fixedly connected to the hard tube connector 52 by threaded fit, the side of the connection tube 51 is obliquely convex, and the soft tube connector 53 is fixedly connected by threaded fit and oblique convex by threaded fit, and a first valve seat 531 is provided on the soft tube connector 53.

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

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

[0027] The camera connection mechanism 4 can also include a sealing cover 44, which can be 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 set 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 thereof 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 display device to facilitate the display of subsequent images.

[0030] In addition, compared with the traditional endoscope, for the operating connection mechanism 5 and the camera connection mechanism 4, the endoscope can be regarded as an inverted setting of the traditional endoscope, 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 meet 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 be used as a water outlet pipe and the other water pipe can be used as a water inlet pipe, and 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 rate flowing 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 imaging fiber, the imaging 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 imaging 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 the 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 be prevented from obstructing the doctor's medical operations when the present invention is in use, making it convenient for the doctor to perform water infusion, use lithotripsy, etc. 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 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 creative concept of the present invention, which all belong to the protection scope of the present invention.
