Description
Technical Field
The invention relates to the field of medical equipment, in particular to an endoscope system.
Background
Endoscope apparatuses are widely used in the medical field, and are configured to have an elongated access portion, and to be inserted into a body to observe the digestive tract, organs, and the like of a human body, or to deliver surgical instruments into the body through forceps tracts to perform a surgery. One end of an access part (namely a lens body) of the endoscope device is inserted into a human body, the other end of the access part is divided into a light guide part, an air supply pipeline and an image signal wire harness, wherein the light guide part and the air supply pipeline are respectively connected with a light outlet hole and/or an air outlet of a cold light source of a host machine, the image signal wire harness transmits an image signal to an image processing device of the host machine, and the image processing device processes image information and outputs a processing result to a display. When the operator finishes the operation of the electronic endoscope or replaces the electronic endoscope, the light guide, the air supply line, and the image signal harness need to be removed.
In order to avoid injury to human eyes due to insertion and removal of an endoscope body in a lamp-on state, a light shielding plate is generally provided on a light emitting path of a light source device, and is opened when the endoscope is inserted and closed when the endoscope is removed. Such a light shielding structure generally further includes an elastic member to automatically return to an original light shielding position when pulled out, and since the elastic force of the elastic member is reduced after a plurality of uses, the light shielding plate may not be returned to the original light shielding position, and thus light shielding may not be effectively performed.
In order to overcome the above disadvantages, a technical scheme of adding a sensing module near a light outlet of a cold light source to detect whether the mirror is pulled out or not and turning off the light source when the pulling out of the mirror is detected is disclosed in chinese patent publication No. CN205979370U in the prior art. The mode is more reliable than adding a light blocking sheet on a light path, and because the space near the light outlet of the cold light source case is small, and the light source irradiates on the light guide part of the mirror body after passing through the collimation optical system, the temperature of the light guide part of the mirror body is increased, the highest temperature is higher than 100 ℃, and devices around the light guide part of the mirror body can be damaged due to the high temperature. The addition of a sensing module near the light outlet of the cold light source chassis is structurally difficult to achieve and risks of damage from high temperatures.
In the prior art, the level change of the in-place detection pin is generally used to judge whether two connectors are connected or disconnected, for example, chinese patent publication No. CN103399254B discloses a method for detecting the in-place of a board card, wherein a first board card is connected with a second board card through the connectors, and the method comprises the steps that when the connection between the second board card and a 2-level in-place signal pin on the first board card is in a stable state, an in-place detection module judges whether the second board card is in place or judges whether the first board card is in place according to the acquisition condition of 1-level and 2-level in-place signals; when the connection between the second board card and the 2-level on-site signal pin on the first board card is in an unstable state, the on-site detection module judges whether the second board card is on site or judges whether the first board card is on site according to the acquisition condition of the 1-level on-site signal. The method uses the level states of at least two 1-level in-place signal pins and 2-level in-place signal pins with the same detection principle to judge the connection state, has a complex structure, and needs to be in a common ground state when the connection of a first board card and a second board card is stable or unstable, and in an endoscope system, the connection of a light guide part in a scope body and an air supply pipeline and a cold light source does not involve electric signals, so the patent is not applicable to the detection of the connection state of a non-electric connector.

The fourth circuit comprises a third contact pin of the host connector, a fourth resistor and a NOT gate, wherein the first end of the fourth resistor is connected with the power end, the second end of the fourth resistor is respectively connected with the third contact pin of the host connector and the input end of the NOT gate, and the output end of the NOT gate is respectively connected with the light source switch end and/or the air pump switch end;
When the mirror body is connected with the host, the third contact pin of the host connector is matched and connected with the third contact pin of the mirror body connector; the resistance ratio of the second resistor to the first resistor is more than or equal to 10:1; the resistance ratio of the fourth resistor to the third resistor is more than or equal to 10:1;
When the first circuit and the second circuit are in fault, the third circuit and the fourth circuit are used as a standby scheme for detecting the connection state of the mirror connector and the host connector;
When the third circuit and the fourth circuit are used together with the first circuit and the second circuit, the in-place detection results of the third circuit and the fourth circuit are combined with the in-place detection results of the first circuit and the second circuit to be used as final in-place detection results, and if the in-place detection results of the third circuit and the fourth circuit are consistent with the in-place detection results of the first circuit and the second circuit, the in-place detection results of the first circuit and the second circuit are considered to be final in-place detection results.
2. The endoscope system of claim 1, wherein the in-situ detection circuit is disposed on an image signal harness connector or a light guide connector or an air supply line connector of the scope and the host.
3. The endoscope system of claim 1, wherein the host computer includes a light source and an image processing device disposed separately or integrally.
4. The endoscope system of claim 1, wherein the host computer further comprises a controller, a signal input of the controller is connected to an output of the in-situ detection circuit, and a signal output of the controller is connected to the light source switch and/or the air pump switch.
