Abstract

The utility model belongs to the technical field of medical instruments, and particularly discloses an endoscope system having an early warning function. The endoscope having the early warning function comprises an endoscope work end portion and an endoscope body, wherein an instrument passage, a water inlet passage and a water outlet passage are arranged inside the endoscope body and extend to the endoscope work end portion in a penetrating mode, a water inlet passage valve, a water outlet passage valve, an instrument passage valve, a light source input end and an image data output end are arranged on the surface of the endoscope body, and an early warning module and an optical lens are arranged at a pilot end portion of the endoscope work end portion. Due to the fact that the early warning module is arranged at the pilot end portion, blood vessels under the surface layer are recognized by utilizing the principle of infrared ray thermal scanning, when a square preset position of the pilot end portion of the endoscope has great vessels and other tissue likely to cause great injuries, an alarm in an image and voice mode is given out to an operator in advance, a doctor is helped to well control the situation in the process of an operation, occurrence of unnecessary bleeding and accidents is effectively prevented, and operation safety of a patient is guaranteed.

Description

A kind of endoscope with warning function

Technical field

This utility model belongs to field of medical appliances, is specifically related to a kind of novel medical instrument that modern medicine is carried out operation on biliary tract, the endoscope that namely has warning function.

Prior art

Endoscope is widely used in each section's Minimally Invasive Surgery, because its superior Wicresoft's effect obtains paying attention to for the patient palliates the agonizing sufferings.Though endoscope can enter in the human body easily and perform a surgical operation, the image that optical lens by endoscope elder generation end obtains inside of human body is presented at the eyes that monitor replaces the doctor, but but generally lack doctor's three-dimensional perception, so under a lot of situations, the doctor can since can not fine judgement scope front end with the tissue nothing between distance, perhaps enter the apparatus of human body and the distance between the tissue by the endoscopic instruments passage, and the blood vessel under the top layer is organized in accidental injury, cause accidental haemorrhage, even malpractice, cause bigger actual bodily harm to patient.

A kind of endoscope that has the early warning module that this utility model proposes, diastimeter by endoscope elder generation end and infrared heat scanheads obtain distance between first end and the tissue substance and the size diameter of blood vessel, thereby the identification by system, to making alarm in advance near the behavior of dangerous blood vessel

The utility model content

The purpose of this utility model is to propose a kind of endoscope with warning function; make the doctor when the operation scope enters the human body operation by this endoscope with warning function; may injure tissue blood vessel or alarm is in advance carried out in the behavior that damages for some; thereby reach the purpose that improves the operation quality, thereby reach the effect of protection operation well.。

In order to reach above-mentioned technical purpose, this utility model is achieved by the following technical programs:

A kind of endoscope with warning function described in the utility model, comprise scope work end, scope main body, to scope work end, penetratingly be provided with instrument channel, intake tunnel, exhalant canal in the described scope main body, the surface of described scope main body is provided with intake tunnel valve, exhalant canal valve, instrument channel valve, light source input, view data outfan, and the first end of described scope work end is provided with early warning module and optical lens.

Further improvement as above-mentioned technology, described early warning module comprises be used to the diastimeter of the first end air line distance of obtaining the place ahead tissue and scope work end, is used for obtaining the infrared heat scanheads that the place ahead is organized the infra-red thermal imaging figure under the top layer and identified blood vessel in the tissue, and the alarm unit that is connected with diastimeter and infra-red heat scanheads.

Described infrared heat scanheads utilizes the temperature difference imaging between blood vessel and the tissue, for the blood vessel of diameter in the imaging more than or equal to 0.5mm, system's identification meets the warning requirement, equals 10mm when the distance of the first end of scope work end and tissue is less than, and will trigger one-level and report to the police; Equal 5mm when the distance of the first end of scope work end and tissue is less than, will trigger secondary and report to the police; Equal 2mm when the distance of the first end of scope work end and tissue is less than, will trigger three grades of warnings, namely in advance to the operator with multi-form warnings such as image and sound.

In this utility model, described scope work end is done smooth and water-proofing treatment, the length range 150～250mm of described scope work end, and its external diameter is smaller or equal to 8mm.

In this utility model, the diameter of described optical lens is more than or equal to 2.8mm, its optical system adopts conventional prism system or electronic CCD imaging system, the internal diameter of described instrument channel is smaller or equal to 3.0mm, described intake tunnel and exhalant canal respectively with the axis of scope main body angle at 45, the diameter of described intake tunnel and exhalant canal is smaller or equal to 1.0mm.

Compared with prior art, the beneficial effects of the utility model are:

Characteristics of the present utility model are in the early warning module of endoscope elder generation end the doctor to be operated some accident behaviors that endoscope does and carry out early warning by designing, the malpractice that may occur because sensation is wrong with the restriction doctor further improves safety and the quality of operation.
