Referring to fig. 1-6, an endoscope, in accordance with one embodiment of the present application, may include an endoscope tube and an operating handle 500. The endoscope comprises an endoscope body 100 and a camera module 200, wherein the endoscope body 100 is provided with an instrument channel 110 and a camera channel 120, and the instrument channel 110 is suitable for an external instrument to pass through so that medical staff can extend the external instrument into the human body without damaging internal tissues of the human body; the image capturing channel 120 is adapted to accommodate the image capturing module 200, and the image capturing module 200 can collect image information of the interior of the human body and transmit the image information to the image processing device for observation by medical staff, and the medical staff can perform operations such as physical examination and operation on the patient according to the image displayed on the image processing device. The operation handle 500 is disposed at the proximal end of the endoscope tube, and is held by medical staff, and the medical staff can push the endoscope tube through the operation handle 500 until the endoscope tube reaches a specified position. Referring to fig. 3 and 4, the image capturing channel 120 and the instrument channel 110 are both eccentrically disposed on the scope body 100, and the image capturing channel 120 and the instrument channel 110 are respectively located at two sides of the central axis of the scope body 100 in the radial direction. Of course, in actual production, the camera channel 120 may also be disposed on the central axis of the scope tube body 100, so that the central axis of the camera module 200 is collinear with the central axis of the scope tube body 100, and at this time, a protrusion is disposed on the outer side wall of the scope tube body 100, and the instrument channel 110 is disposed on the protrusion, so that an external instrument passing through the instrument channel 110 is in an external state.
Specifically, referring to fig. 2 and 3, the camera module 200 includes a camera 210 and a camera harness 220, the camera harness 220 is electrically connected to the camera 210 and an image processing device, and the camera 210 is configured to transmit acquired image information to the image processing device, which is used for imaging.
In actual production, referring to fig. 1 to 4, in order to avoid that the camera 210 is scratched to affect the imaging of the picture, a protective cover 130 is further disposed at a position corresponding to the image capturing channel 120 at the distal end of the lens tube body 100, so as to protect the camera 210.
In a preferred embodiment, at least the scope body 100 of the endoscope can rotate around the central axis of the camera module 200 relative to the operation handle 300, so that the rotation of the scope body 100 can no longer be limited by the operation handle 500, and the scope body 100 is in an eccentric position relative to the central axis of the camera module 200, that is, the central axis of the camera channel 120, because the instrument channel 110 is located at the eccentric position, when the scope body 100 rotates, the external instrument located in the instrument channel 110 must displace and rotate around the central axis of the camera module 200 along with the scope body 100. At this time, if the external apparatus is a rotary cutter, medical staff can rotate the endoscope body 100 to realize the rotary cutting of the rotary cutter to the internal tissues of the human body, and the operation is more convenient.
Specifically, the endoscope provided by the embodiment can be applied to hysteroscopic hysteromyoma cutting or similar scenes, medical staff can examine the conditions in the patient through the endoscope, and can guide external instruments into the patient through the instrument channel 110 to directly conduct rotary cutting operation, so that the operation flow is simplified, the rapid propulsion of the operation process is facilitated, and the practicability is strong.
In this embodiment, at least the endoscope body 100 can rotate around the central axis of the camera module 200 relative to the operation handle 300, and the rotation can be specifically divided into two cases:
1) Referring to fig. 1 to 4, the scope body 100 is rotatable about a central axis of the camera module 200 with respect to the operation handle 500, and the camera module 200 as a whole serves as a fixed axis of rotation of the scope body 100, and the camera module remains stationary while the endoscope is rotated. At this time, medical staff can drive the rotary cutter in the instrument channel 110 to rotate through rotating the lens tube body 100 to realize the rotary cutting of the rotary cutter to the internal tissue of the human body, simultaneously, in the rotary cutting process, the camera module 200 can not be driven by the lens tube body 100, the image information that it gathered can not rotate either, so that the observation of medical staff is facilitated, the promotion of the operation is more facilitated, and the practicability is strong.
2) Referring to fig. 5 to 8, the scope body 100 may rotate about the central axis of the camera module 200 with respect to the operation handle 500, and at the same time, the camera module 200 may rotate together with the scope body 100. At this time, in order to further facilitate the observation of medical staff, the image processing apparatus may perform rotation processing on the image information collected by the image capturing module 200, and display the image information after the image information is adjusted to a suitable angle. Specifically, if the camera module 200 rotates 90 ° counterclockwise, the image processing device will rotate the received image information collected by the camera module 200 by 90 ° clockwise, so as to ensure that the image information observed by the medical staff will not rotate, and facilitate the operation of the medical staff.
In both cases, the angle range in which the scope body 100 can rotate with respect to the operation handle 500 is preferably 300 ° to 340 °. Specifically, in the initial state, the angle of the endoscope body 100 relative to the operation handle 500 is set to be 0 °, and in the use process, the medical staff can rotate the endoscope body 100 clockwise along the circumferential direction of the endoscope body 100, and the rotation range is 150 ° -170 °; in contrast, medical personnel can rotate the scope body 100 counterclockwise along the circumference of the scope body 100, with a range of rotation of 150-170. Therefore, the surgical operation device can meet the clinical operation requirements of most rotary cutting operations, especially hysteroscopic cutting hysteromyoma, and has strong practicability.
Specifically, referring to fig. 4, when the lens body 100 can rotate around the central axis of the camera module 200 relative to the operation handle 500 and the camera module remains stationary relative to the operation handle 500, an indication mark 131 can be disposed on the protective cover 130 to identify the relative rotation angle of the lens body 100 and the camera module 200. In this way, when the lens body 100 and the camera module 200 rotate relatively, the position of the indication mark 131 in the image information collected by the camera module 200 is also changed. Because the camera module 200 does not rotate, the collected image information does not rotate, so that medical staff can directly observe the rotation angle of the lens tube body 100 from the imaging of the image processing equipment.
Specifically, referring to fig. 4, the angle is marked as a short line extending along the radial direction of the lens body 100, and of course, in actual production, the extending angle of the short line may slightly deviate, and does not necessarily extend strictly along the radial direction of the lens body 100, which is within the scope of the present embodiment.
In this embodiment, the angle sensor 401 may be further disposed at the distal end of the endoscope tube body 100 to obtain more accurate rotation information (such as rotation angle and rotation speed), and the rotation information may be directly displayed on the image processing device for viewing by medical staff.
Of course, in actual production, if the camera module 200 and the endoscope body 100 rotate together, that is, if the endoscope is in the second condition, the angle sensor 401 may be disposed at the distal end of the endoscope body 100 to obtain rotation information (such as rotation angle and rotation speed) of the camera module 200 and the endoscope body 100, and the rotation information may be displayed on the image processing apparatus directly for viewing by medical staff.
Further, referring to fig. 2 and 5-8, the endoscope tube further includes a knob 300. Specifically, referring to fig. 2, if the endoscope is the first case, the knob 300 is disposed at the proximal end of the endoscope body 100 and adapted to drive the endoscope body 100 to rotate relative to the operating handle 500. Referring to fig. 5 to 8, if the endoscope tube is the second case, the rotation handle 300 should be disposed at the proximal end of the camera module 200, and adapted to drive the camera module 200 and the endoscope tube body 100 to rotate synchronously around the central axis of the camera module 200 relative to the operation handle 500.
Specifically, the operating handle 500 includes a housing 510, and the proximal end of the lens tube body 100 and the proximal end of the camera module 200 are both installed in the housing 510, meanwhile, a first avoiding hole 511 is formed in the housing 510, the edge of the rotary handle 300 extends to the outside of the housing 510 through the first avoiding hole 511, and medical staff can use the left hand holding the operating handle 500 to toggle the rotary handle 300, so as to realize one-hand operation, thereby driving the lens tube body 100, or the camera module 200 and the lens tube body 100 to rotate, and the right hand can be vacated to operate external instruments.
Specifically, referring to fig. 1, 5, 7 and 8, the rotary handle 300 is in a dial wheel or roller structure, and the rotary handle 300 is provided with a plurality of grooves 320 along the circumferential direction, which is convenient for the medical staff to dial. Of course, in actual production, a plurality of anti-slip bumps or raised strips may be disposed on the side wall of the knob 300, which are not described in detail herein, and are all within the scope of the present application.
Referring to fig. 6, an angle encoder 402 or an angle sensor 401 (e.g. a potentiometer) or an inertial navigation unit is disposed at the proximal end of the rotation handle 300, so as to collect rotation information of the rotation handle 300, thereby obtaining rotation information of the lens body 100 or the camera module 200, and the rotation information can be transmitted to an image processing device for obtaining by medical staff.
Of course, if the angle sensor 401 is already disposed at the distal end of the lens tube body 100, the rotation handle 300 does not need to be further provided with the angle encoder 402 or the angle sensor 401 or the inertial navigation unit to measure the rotation angle.
It should be noted that, when the camera module 200 and the endoscope body 100 rotate together, that is, the endoscope is in the second condition, the image processing apparatus can rotate the image information collected by the camera module 200 according to the rotation information after obtaining the rotation information of the camera module 200 or the endoscope body 100, so that the image displayed by the image processing apparatus cannot rotate due to the rotation of the camera module 200, which is convenient for the medical staff to observe.
In one embodiment, referring to fig. 3, the outer diameter of the camera harness 220 is smaller than the inner diameter of the camera channel 120, there is a gap between them, and the distal end of the lens body 100 is provided with an opening 140, which communicates with the camera channel 120. At this point, the gap between the camera harness 220 and the camera channel 120, and the aperture 140 in the scope body 100, may be used to feed or drain fluid out of the surgical site. Specifically, if instrument channel 110 is used to feed fluid to the surgical site, then the gap between camera harness 220 and camera channel 120, and aperture 140 in scope body 100, are used to drain fluid outwardly; conversely, the gap between the camera harness 220 and the camera channel 120, and the opening 140 in the scope body 100, is used to feed fluid into the surgical site, and the instrument channel 110 is used to drain fluid out. In this embodiment, the instrument channel 110 and the image capturing channel 120 on the scope body 100 are all connected with a water pipe, and the water pipe is subjected to flexible overstocking.
At this time, if the camera module 200 rotates together with the endoscope body 100, that is, when the endoscope is in the second condition, the second avoidance hole 310 needs to be formed in the rotation handle 300 disposed at the proximal end of the camera module 200, so as to avoid the water pipe and other components or the wire harness in the housing 510 of the operation handle 500, so that the water pipe is prevented from being entangled with other components or the wire harness in the housing 510 when the camera module 200 rotates relative to the operation handle 500, which is inconvenient to use.
It should be noted that, in the above embodiment in which all the lens bodies 100 can rotate around the central axis of the camera module 200 relative to the operation handle 500 and the camera module 200 does not rotate, the camera module 200 is fixed in the housing 510 of the operation handle 500 like a cantilever structure, and if the camera module 200 is required to support the lens bodies 100 for rotation, a tube (not shown) with higher rigidity needs to be sleeved outside the camera harness 220.
In a specific embodiment, the tube body may be a double-layer hollow tube with a certain rigidity, that is, the tube body includes an inner tube and an outer tube sleeved outside the inner tube, the proximal end of the inner tube is connected with the proximal end of the outer tube, and the distal end of the inner tube is connected with the distal end of the outer tube. At this time, a fluid passage through which fluid can flow is formed between the inner tube and the outer tube. Specifically, the distal end of the double-layered hollow tube is provided with an opening, and the water pipe is connected to the fluid channel on the double-layered hollow tube, so that the opening 140 on the scope tube body 100 is matched with the double-layered hollow tube, and can also feed liquid into or discharge liquid out of the operation site.
Specifically, referring to fig. 1 and 2, since the lens body 100 can rotate around the central axis of the camera module 200 relative to the operation handle 500, in consideration of most cases, the lens body 100 has an asymmetric structure along the central axis of the camera module 200, and the boss 150 can be disposed at the proximal end of the lens body 100, so that at least the proximal end of the lens body 100 has a symmetric circular structure along the central axis of the camera module 200. At this time, the third avoidance hole for avoiding the lens tube body 100 is formed in the casing 510 of the operating handle 500, and is a circular hole, so that the third avoidance hole can be well attached to the outer contour of the proximal end of the lens tube body 100, and the structural arrangement is reasonable and attractive.
The application also provides an endoscope system comprising the image processing device and the endoscope provided by any one of the embodiments. The camera module 200 includes a camera 210 and a camera harness 220, the camera harness 220 is electrically connected to the camera 210 and an image processing device, the camera 210 is configured to transmit collected image information to the image processing device, and the image processing device is used for imaging.
