Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to endoscope device.
Background
Endoscopes have gained widespread acceptance in the medical community because they provide a means for performing surgery with minimal trauma to the patient while allowing the physician to view the internal anatomy of the patient. Over the years, many endoscopes have been developed and classified according to specific applications, such as cystoscopes, colonoscopes, laparoscopes, upper gastrointestinal endoscopes, and the like. The endoscope may be inserted into a natural opening in the body, or through an incision in the skin.
Endoscopes are typically elongated tubular shafts, rigid or flexible, having a camera or fiber optic lens assembly at their distal end. The shaft is connected to a handle, which sometimes includes an eyepiece for direct viewing. Viewing via an external screen is also generally possible. Various surgical tools may be inserted through the working channel in the endoscope for performing different surgical procedures.
Since the endoscope is used in a body having a high humidity and a temperature higher than room temperature, when the distal end portion of the insertion portion is inserted into the body, optical elements such as a lens cover and an objective lens disposed at the distal end portion may be fogged, and a clear image may not be obtained. In addition, the optical element inevitably has impurities or pollutants, so that the endoscope can rapidly achieve the self-cleaning effect, which is also a technical problem to be solved in the prior art.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a technical scheme realizes as follows:
an endoscope apparatus including an endoscope having an insertion portion to be inserted into a subject, an operation portion located at a rear end of the insertion portion, a universal cable extending from the operation portion, and a control device provided at an end portion of the universal cable, the endoscope apparatus including:
an inner tube that houses an image forming unit having an optical element at a distal end of an endoscope;
an outer sleeve accommodating a hot air pipe capable of ejecting hot air to heat the optical element;
and the air exhaust pipe is of a cylindrical structure, surrounds the periphery of the inner sleeve, and sucks hot air and impurities so as to keep the optical element clear.
Further, a front end portion of the insertion portion has a seal cover.
Further, the operation part comprises a switch of a hot air pipe and a switch of an air exhaust pipe.
Further, the operation portion includes a bending knob capable of bending the insertion portion in the up-down direction and the left-right direction.
Further, the operation unit includes a treatment instrument insertion unit into which the living body forceps and/or the laser scalpel are inserted into the body cavity of the subject.
Further, a first temperature sensor is arranged in the outer sleeve, so that the temperature in the hot air pipe is measured.
Further, a second temperature sensor is arranged in the outer sleeve, so that the temperature of the optical element is measured.
Further, the control device includes an arithmetic unit that calculates a temperature of the hot air from information of the first temperature sensor and calculates a temperature of the optical element from information of the second temperature sensor, an alarm unit that determines whether or not an abnormality occurs from the temperature of the hot air measured by the first temperature sensor and the temperature of the optical element measured by the second temperature sensor based on a set temperature, and outputs the abnormality to the control unit, so that the control unit adjusts the temperature in real time.
Compared with the prior art, the beneficial effects of the utility model are that: through the injection of hot air pipe to optical element, can carry out instant heating to optical element, prevent optical element's fogging, can clean possible impurity or pollutant of optical element through the air again, to the impurity or the pollutant that blow up, the utility model discloses an exhaust tube pumps to reach optical element's antifog and automatically cleaning effect.
