[0037] The utility model discloses an endoscope which is mainly used in orthopedic surgery and integrates a lighting device, a camera device, a water outlet device and an instrument channel for puncture devices and other diagnostic and treatment instruments.

[0038] like Figures 1 to 3As shown, the endoscope of the utility model comprises a handle 1, on which a tubular endoscope rod 2 is provided, and on one end of the endoscope rod 2 away from the handle 1, an illumination unit 5 and a camera unit 6 are provided, wherein the illumination unit 5 adopts an LED light source in this embodiment, and the camera unit 6 adopts an electronic camera in this embodiment. At the same time, in order to facilitate the endoscope rod 2 to enter the patient's body, the endoscope rod 2 is tilted and opened away from the handle 1. An electrical interface 104 is provided on the handle 1, and the illumination unit 5 and the camera unit 6 are both electrically connected to one end of the electrical interface 104, and the other end of the electrical interface 104 is detachably connected to an external power source.

[0039] like Figures 4 to 6 As shown, the endoscope rod 2 is provided with a first operating channel 201 arranged along the axial direction of the endoscope rod 2, the first operating channel 201 is tubular and the first operating channel 201 passes through the endoscope rod 2. The handle 1 is provided with a second operating channel 102, the second operating channel 102 is also tubular, the first end of the second operating channel 102 is connected to the outer surface of the handle 1, and the connection between the second operating channel 102 and the outer surface of the handle 1 is provided with an opening chamfer, and the setting of the opening chamfer facilitates the entry of diagnostic and treatment equipment such as a puncture device into the second operating channel 102 from the first end of the second operating channel 102, and the second end of the second operating channel 102 is connected to the first operating channel 201. In detail, the second end of the second operating channel 102 is inserted into the endoscope rod 2, and the second operating channel 102 and the first operating channel 201 are connected to form an integral channel. The surgeon can insert the puncture device and other diagnostic and treatment equipment into the second operating channel 102 from the first end of the second operating channel 102, and pass the puncture device and other diagnostic and treatment equipment out from the end of the first operating channel 201 away from the handle 1. When the surgeon finds the surgical position, the puncture device and other diagnostic and treatment equipment can be operated close to one end of the handle 1, thereby realizing the operation of the diagnostic and treatment equipment and performing the surgical operation.

[0040] like Figure 1 , Figures 5 to 10 As shown, the endoscope of the present invention includes a fixing member 3 on the handle 1, the fixing member 3 is tubular and sleeved outside the endoscope rod 2, and a gap is provided between the fixing member 3 and the endoscope rod 2. Figure 1As shown, the handle 1 is provided with a fixing hole 101 that matches the fixing member 3; during assembly, the fixing member 3 is inserted into the fixing hole 101 together with the endoscope rod 2, so that the handle 1, the endoscope rod 2 and the fixing member 3 form a whole. Fig.10 As shown, the handle 1 is provided with a water tank, and the water tank cooperates with the fixing member 3 to form a first water storage chamber 4. Specifically, the side wall of the fixing member 3 closes the opening of the water tank, and the side wall of the fixing member 3 and the water tank are combined to form a closed cavity. The fixing member 3 is provided with a water inlet 301, and the water inlet is in the shape of a hole. The water inlet 301 is connected to the first water storage chamber 4, and the gap between the fixing member 3 and the endoscope rod 2 is connected to the water inlet 301. The handle 1 is provided with a water interface 103, one end of the water interface 103 is connected to the first water storage chamber 4, and the other end of the water interface 103 is detachably connected to an external water supply device. A first sealing member 7 is provided between the endoscope rod 2 and the fixing member 3 , and the first sealing member 7 is a rubber sealing ring. The first sealing member 7 is arranged around the endoscope rod 2 , and the first sealing member 7 is arranged at one end of the endoscope rod 2 close to the handle 1 , and the water inlet 301 is arranged on the side of the first sealing member 7 facing away from the handle 1 .

[0041] like Figure 6 As shown, when the endoscope of the utility model is in use, an external water supply device is connected to the water interface 103, and the external water supply device is used to provide physiological saline. The physiological saline enters the first water storage chamber 4 through the water interface 103, and then the physiological saline in the first water storage chamber 4 enters the gap between the fixing member 3 and the endoscope rod 2 through the water inlet 301. Due to the obstruction of the first sealing member 7, the physiological saline can only flow toward the side away from the handle 1, and finally the physiological saline flows out from the gap between the fixing member 3 and the endoscope rod 2 near the camera 6.

[0042] The utility model arranges the tubular fixing part 3 on the handle 1, arranges the water inlet 301 on the fixing part 3, and arranges the endoscope rod 2 in the fixing part 3, so that the endoscope of the utility model has the function of discharging water around the endoscope rod, and at the same time makes the structures of the fixing part 3 and the handle 1 simpler, the assembly between the endoscope rod 2, the fixing part 3 and the handle 1 is more convenient, and the production cost of the endoscope of the utility model is low.

[0043] At the same time, if Figure 5 and Figure 6As shown, a water supply pipe 105 is provided in the handle 1, one end of the water supply pipe 105 is connected to the water interface 103, and the other end of the water supply pipe 105 is connected to the water storage tank, that is, the other end of the water supply pipe 105 is connected to the first water storage chamber 4. If the first water storage chamber 4 is not provided, the water supply pipe 105 needs to be directly connected to the water inlet 301. If the water supply pipe 105 is directly connected to the water inlet 301, when the fixing member 3 and the handle 1 are assembled, it is difficult to ensure the alignment between the water supply pipe 105 and the water inlet 301, and it is difficult to ensure that the water supply pipe 105 and the water inlet 301 are kept sealed. Therefore, in the utility model, a water storage tank is provided on the handle 1, and a second sealing member 9 is provided on both sides of the water storage tank. When the fixing member 3 is assembled to the handle 1, the fixing member 3 and the water tank cooperate to form the first water storage chamber 4. The second sealing member 9 is arranged on both sides of the water storage chamber. The second sealing member 9 is also arranged between the fixing member 3 and the handle 1 to ensure the sealing of the first water storage chamber 4. In this embodiment, the water storage chamber is annular, so after the opening of the water storage chamber is closed by the fixing member 3, the first water storage chamber 4 is also annular. The second sealing member 9 is two sealing rings arranged on both sides of the water storage chamber. The second sealing member 9 is also sleeved on the outside of the fixing member 3, and the second sealing member 9 fills the gap between the fixing member 3 and the handle 1. Therefore, when the fixing member 3 is assembled into the fixing hole 101, there is no need to consider the problem that the water supply pipe 105 is difficult to align and seal with the water inlet 301. Due to the provision of the water tank, the endoscope of the utility model is convenient for assembling the fixing member 3 on the one hand; on the other hand, the first water storage chamber 4 forms a water storage chamber, which also plays a role in stabilizing the water pressure of the water outlet, thereby reducing the impact of water pressure fluctuations of an external water supply device on the water pressure of the endoscope.

[0044] In this embodiment, Figures 6 to 10As shown, in this embodiment, the fixing member 3 includes a first pipe member 302 and a second pipe member 303. The first pipe member 302 and the second pipe member 303 are both in the shape of a circular tube and are coaxially arranged. One end of the first pipe member 302 is connected to one end of the second pipe member 303. The water inlet 301 is arranged on the first pipe member 302. The endoscope rod 2 is arranged in the first pipe member 302 and the second pipe member 303. In order to facilitate the insertion of the fixing member 3 into the fixing hole 101, the outer diameter of the first pipe member 302 is larger than the outer diameter of the second pipe member 303. During the assembly process of the fixing member 3 and the handle 1, the first pipe member 302 is inserted into the fixing hole 101. The larger outer diameter of the first pipe member 302 facilitates the assembly of the first pipe member 302 during assembly. In other embodiments, in order to facilitate faster insertion of the first pipe 302 into the fixing hole 101 , the first pipe 302 may also be a pipe with a square exterior and a circular interior, and the fixing hole 101 may be in a square shape matching the first pipe 302 .

[0045] like Fig.11 As shown, in other embodiments, the cross section of the second pipe 303 is located in the cross section of the first pipe 302 on the plane where the second pipe 303 is connected to the first pipe 302. The cross section of the second pipe 303 is set away from the axis of the first pipe 302, and the water inlet 301 is set on the wall of the first pipe 302 away from the connection between the second pipe 303 and the first pipe 302. Fig.11 In the embodiment, the axis direction of the first pipe 302 is arranged along the horizontal direction, the first pipe 302 is divided into an upper pipe wall and a lower pipe wall along the gravity direction, the connection between the second pipe 303 and the first pipe 302 is arranged close to the lower pipe wall of the first pipe 302, and the water inlet 301 is arranged on the upper pipe wall of the first pipe 302, that is, the water inlet 301 is arranged away from the connection between the second pipe 303 and the first pipe 302. In the gravity direction, the connection between the second pipe 303 and the first pipe 302 is located below the water inlet 301. Therefore, when the first pipe 302 is filled with physiological saline, due to the gravity of water, the water pressure at the connection between the second pipe 303 and the first pipe 302 is larger than the water pressure near the water inlet 301, which is conducive to the flow of physiological saline from the second pipe 303, and the water pressure of the external water supply device can be reduced, thereby reducing the energy consumption of the external water supply device.

[0046] like Figure 2 and Figure 3As shown, in this embodiment, a tongue-shaped piece 304 is provided on the side of the fixing member 3 away from the handle 1. Since the endoscope of the utility model is used for orthopedic surgery, the tongue-shaped piece 304 can be passed through the gap between the bone and the nerve near the bone during the orthopedic surgery, and the nerve near the bone is located on the side of the tongue-shaped piece 304 away from the endoscope rod 2, and the bone is located on the side of the tongue-shaped piece 304 close to the endoscope rod 2. By setting the tongue-shaped piece 304, the diagnostic and treatment instruments in the first operating channel 201 can avoid accidental injury to the nerve near the bone when performing surgical operations on the bone.

[0047] like Figure 7 As shown, in this embodiment, the fixing member 3 further includes a blocking portion 305, which is annular and is disposed at the connection between the first tube member 302 and the second tube member 303. When the first tube member 302 and the fixing hole 101 are assembled with each other, it can be arranged that when the blocking portion 305 abuts against the handle 1, the first tube member 302 and the fixing hole 101 are installed in place.

[0048] The utility model further facilitates the assembly of the endoscope by disposing the blocking portion 305 .

[0049] like Figure 4 As shown, in this embodiment, a reinforcing member 8 is provided on the fixing member 3, and the reinforcing member 8 is arranged to abut against the handle 1. Specifically, the blocking portion 305 and the second pipe 303 are both connected to the reinforcing member 8. Since the second pipe 303 is relatively long, the reinforcing member 8 is arranged to prevent the second pipe 303 from being bent and deformed by force.

[0050] like Fig.12 and Fig.13 As shown, the utility model also provides an endoscope kit, including the endoscope and the external operation kit 10 described above, and the external operation kit 10 includes a first sleeve 1001 and a second sleeve 1002. The tube wall of the first sleeve 1001 and the tube wall of the second sleeve 1002 are connected to each other, and the first sleeve 1001 is sleeved on the outside of the fixing member 3. Specifically, the first sleeve 1001 is sleeved on the outside of the second pipe 303, and the second sleeve 1002 can be used for diagnostic and therapeutic instruments such as tissue clamps to pass through. The utility model is provided with the external operation kit 10 sleeved on the outside of the second pipe 303, so that in orthopedic surgery, two diagnostic and therapeutic instruments can be respectively inserted into the second sleeve 1002 and the first operation channel 201 at the same time, and then two diagnostic and therapeutic instruments such as tissue clamps can be operated simultaneously during the operation, which is convenient for surgical operation.

[0051] In this embodiment, Fig.12 and Fig.13As shown, the first sleeve 1001 and the second sleeve 1002 are tilted, and the acute angle direction of the first sleeve 1001 and the second sleeve 1002 is set towards the direction away from the handle 1, so that the ends of the two diagnostic and treatment instruments away from the handle 1 can be close to each other, which is convenient for surgical operations.

[0052] In this embodiment, Fig.13 As shown, the first sleeve 1001 can rotate around the fixing member 3. Specifically, a rotation groove can be provided on the inner wall of the second sleeve 1002, and the plane where the rotation groove is located is parallel to the plane perpendicular to the axis of the second sleeve 1002; a rotation ring matching the rotation groove is provided on the outer wall of the second pipe 303. The utility model allows the first sleeve 1001 to rotate around the axis of the second pipe 303, so that the surgeon can adjust the relative position of the diagnostic and treatment instruments in the first sleeve 1001 and the diagnostic and treatment instruments in the first operating channel 201 during the surgical operation, which is convenient for the surgeon to perform the surgical operation.

[0053] In this embodiment, a rotating handle 1003 is provided on the first sleeve 1001. In detail, the rotating handle 1003 is arranged at one end of the first sleeve 1001 close to the handle 1. When the first sleeve 1001 needs to rotate around the fixing member 3, the rotating handle 1003 can be operated to realize the rotation of the first sleeve 1001.

[0054] In summary, the utility model provides the tubular fixing member 3 on the handle 1, and provides the water inlet 301 on the fixing member 3, and at the same time, the endoscope rod 2 is provided in the fixing member 3, so that the endoscope of the utility model has the function of discharging water around the endoscope rod, and at the same time, the structure of the fixing member 3 and the handle 1 is relatively simple, the assembly between the endoscope rod 2, the fixing member 3 and the handle 1 is relatively convenient, and the production cost of the endoscope of the utility model is low. And the setting of the first water storage chamber 4 reduces the influence of the water pressure fluctuation of the external water supply device on the water pressure of the endoscope. And the setting of the tongue-shaped piece 304 can prevent the diagnosis and treatment instruments in the first operating channel 201 from accidentally injuring the nerves near the bone when performing surgery on the bone. The setting of the blocking part 305 further facilitates the assembly of the endoscope. And the setting of the reinforcing member 8 makes the second pipe 303 less likely to bend and deform under force. By setting the first pipe 302 away from the axis of the first pipe 302, and setting the water inlet 301 on the wall of the first pipe 302 away from the connection between the first pipe 302 and the second pipe 303, the water pressure of the external water supply device can be reduced. By setting the external operation kit 10 on the outside of the second pipe 303, two diagnostic and treatment instruments can be respectively inserted into the second sleeve 1002 and the first operation channel 201 during orthopedic surgery, so that two diagnostic and treatment instruments such as tissue clips can be operated simultaneously during surgery, which is convenient for surgical operation. By setting the first sleeve 1001 and the second sleeve 1002 at an angle, surgical operation is convenient. By setting the first sleeve 1001 to rotate around the fixing member 3, it is convenient for the surgeon to perform surgical operations.

[0055] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention.
