Wherein the chip may be a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS).
In the present embodiment, the field angle of the image capturing unit refers to the field range in which the image capturing unit can capture an image. In actual use, the electronic endoscope operator holds the proximal end 102 of the electronic endoscope. Since the angle of view of the imaging unit is biased toward the proximal end 102 of the catheter 1, the electronic endoscope operator can be positioned on one side of the patient to operate the electronic endoscope to observe the lesion of the patient, and can acquire an image of the lesion of the patient toward the other side. Specifically, the camera of the camera unit can collect light reflected by the target object towards the other side, the collected light is transmitted to the chip, and the collected light is converted into a corresponding digital signal through the chip to obtain an image of the focus of the patient towards the other side.
The electronic endoscope provided by the embodiment of the application comprises a catheter 1, wherein the catheter 1 comprises a distal end part 101 and a proximal end part 102; the camera unit is mounted at the distal end 101 of the catheter 1 and the field angle of the camera unit is biased towards the proximal end 102 of the catheter 1. In actual use, the electronic endoscope operator holds the proximal end 102 of the electronic endoscope. Therefore, the angle of view of the imaging unit is biased toward the electronic endoscope operator, and thus the electronic endoscope operator can operate the electronic endoscope to acquire an image of a lesion of the patient even if the electronic endoscope operator is located on a different side of the patient from the surgical instrument operator. Therefore, the endoscope operator and the surgical instrument operator can be positioned on different sides of the patient, the electronic endoscope operator is prevented from influencing the normal operation of the surgical instrument operator, and the multi-person cooperation can be conveniently completed.

The slope is a side surface connecting the opening edge of the groove with the bottom edge of the groove 1012 on the same side, the side surface being inclined toward the opening of the groove, and thus the image pickup unit mounting section 2 provided at the slope is also inclined toward the opening of the groove. Further, since the slope of the distal groove 1012 away from the proximal portion 102 is inclined toward the opening of the groove, the view angle of the imaging unit in the imaging unit mounting portion 2 can be biased toward the proximal portion 102 of the catheter 1, thereby acquiring an image of the lesion of the patient toward the other side.
In one embodiment, the slope is at an angle of 30-50 degrees relative to the bottom of the groove.
In one embodiment, the ramp surface is angled at 30 degrees relative to the bottom of the groove. In another embodiment, the slope is at an angle of 45 degrees relative to the bottom of the groove.
