Abstract
The utility model belongs to a surgical diagnosis and treatment device in the medical field and particularly relates to a device for automatically maintaining frontal imaging during rotary imaging of a surgical endoscope. The device solves the problems in the prior art that a surgeon identifies a corrective frontal position in an image displayed by a display device according to the real-time rotation angle of a lens during use of the existing surgical endoscope, which adds difficulty to the endoscopic surgery which is complicated. The key points of the technical scheme are as follows: the optical lens of the endoscope is integrally connected with a rotation position sensor, the rotation position sensor is connected with a microprocessor through a wire, the microprocessor reads a rotation position signal and sends a command to a stepping motor, the microprocessor is connected with the stepping motor through a wire, a driving gear connected with the output shaft of the stepping motor is meshed with a driven gear arranged on an electrooptical signal sensor, and the electrooptical signal sensor is connected with an output wire. The device can be applied to surgical diagnosis and treatment and has the advantages of being convenient to operate, increasing the efficiency and reducing the errors.
Description
Technical field: this utility model belongs to the operation diagnosing and treating apparatus of medical field, particularly automatically keeps the device of normotopia imaging in a kind of Surgical cavity mirror rotation shooting.
Background technology: the basic structure of existing surgical operation chamber used mirror is: chamber lens head and photoelectric signal sensor connect into the one of closure state, and the chamber lens head mostly is 30 and spends the inclination angle, in order to broaden one's vision.In operation, according to the operator needs, rotating lens can obtain the large Radix Rumicis surgical field of view of different directions.But along with the rotation of camera lens, in display, shown image rotates along with rotation, makes operator must distinguish according to instant rotation of lens angle the correct orientation of image in display, makes like this this complicated endoscope-assistant surgery more difficult.
The utility model content: the purpose of this utility model is exactly to propose automatically to keep the technical scheme of the device of normotopia imaging in a kind of Surgical cavity mirror rotation shooting, background technology exists to solve: existing Surgical cavity mirror with the time operator must distinguish according to instant rotation of lens angle the correct orientation of image in display, endoscope-assistant surgery of complexity is more difficult to make like this this.Solving this technical problem the technical scheme that adopts is: automatically keep the device of normotopia imaging in a kind of Surgical cavity mirror rotation shooting, it is characterized in that chamber mirror optical lens and rotational position sensor are connected as a single entity, rotational position sensor connects the microprocessor that reads rotating position signal and send instruction to stepper motor by wire, microprocessor connects stepper motor by wire, the driving gear that the stepper motor output shaft connects and the engagement of the driven gear on photoelectric signal sensor, photoelectric signal sensor connects output lead.Wherein, chamber mirror optical lens and the photoelectric signal sensor with rotational position sensor forms closure state.
the beneficial effect that this utility model has compared with the prior art is: owing to adopting technique scheme, utilize the rotational position sensor that is arranged on the mirror optical lens of chamber in operation, lens location rotational angle information is sent to microprocessor immediately, microprocessor reads the rotation of lens angle information, and send according to this pulse command to stepper motor, stepper motor is made the corresponding anglec of rotation thereupon, and make same angle number rotation with the rotation of lens opposite direction by the gear driven photoelectric imaging sensor, make that in display, shown picture position remains the normotopia imaging, operator can be observed the imaging under any rotation of lens state easily, be of value to and facilitate diagnosis and treatment, raise the efficiency, reduce error.
Description of drawings: Fig. 1 is overall structure schematic diagram of the present utility model.
the specific embodiment: with reference to figure 1, automatically keep the device of normotopia imaging in a kind of Surgical cavity mirror rotation shooting, it is characterized in that chamber mirror optical lens 7 and rotational position sensor 3 are connected as a single entity, rotational position sensor 3 connects the microprocessor 8 that reads rotating position signal and send instruction to stepper motor by wire, microprocessor 8 connects stepper motor 6 by wire, the driving gear 5 that stepper motor 6 output shafts connect and 4 engagements of the driven gear on photoelectric signal sensor 2, photoelectric signal sensor 2 connects output lead 1, chamber mirror optical lens 7 with rotational position sensor 3 forms closure state with photoelectric signal sensor 2.
