Description
The application divides an application, and the application number of original bill application is 200580008859.6, and international application no is PCT/JP2005/004534, and the applying date is on March 15th, 2005, and denomination of invention is " endoscope balloon control device ".
Technical field
The present invention relates to endoscope balloon control device, and relate to the endoscope balloon control device of the pressure in sacculus and the sacculus of insertion section front end peripheral part that is arranged on trocar sheath of insertion section front end peripheral part that may command is arranged on endoscope.
Background technology
Generally speaking, in the digestive tube inspection, use splanchnoscopy mostly.In this splanchnoscopy; Be inserted into the deep digestive tube to the insertion section of endoscope, under the for example enteral situation, only when being pressed into above-mentioned insertion section; Exert all one's strength and be difficult to be delivered to above-mentioned insertion section front end owing to the bending of complicated intestinal tube, it is difficult being inserted into the deep.For example, above-mentioned endoscope is in the time will making unnecessary bending or the deflection of inserting the above-mentioned endoscope produces through the deep stretch out to retract, because above-mentioned insertion section front end also breaks away from, thereby can not eliminate bending or deflection, the deep is inserted and become difficult.
Therefore; Proposed a kind of endoscope apparatus, this device is temporarily fixed on the above-mentioned intestinal tube this inflation because of the front end peripheral part installation sacculus in the above-mentioned insertion section of above-mentioned endoscope; Thereby when the unnecessary bending that makes above-mentioned endoscope or deflection are stretched out, prevent that the front end of above-mentioned insertion section breaks away from.
And; In the prior art; A kind of endoscope apparatus has also been proposed; This device is provided with the trocar sheath of inserting the above-mentioned insertion section be connected with above-mentioned endoscope, and at the front end peripheral part of this trocar sheath sacculus is installed, and makes the flat raising that comes to realize to above-mentioned endoscope apparatus the operation performance of suitably expanding or contract of the sacculus of sacculus and the above-mentioned endoscope of this trocar sheath.For example; In the open 2002-301019 communique of Japan's patent; A kind of endoscope apparatus is disclosed; This device is to the sacculus of above-mentioned endoscope and the sacculus of above-mentioned trocar sheath, when using control unit to measure air pressure in each sacculus to control the pressure in above-mentioned each sacculus, from pump installation to these sacculus air supplies.
The disclosed endoscope apparatus of above-mentioned communique is under the material condition of different of the sacculus of the sacculus of above-mentioned endoscope and above-mentioned trocar sheath, and perhaps when sacculus is changed at every turn under the material condition of different, even flow is identical, the expansion appearance of sacculus is also different.Therefore, even the material of sacculus/kind is different,, also be necessary to control gas supply flow to above-mentioned each sacculus according to the material of sacculus in order to keep constant expansion appearance.And, in order to control the gas supply flow or the air feed of above-mentioned each sacculus are pressed, be necessary to measure service life to above-mentioned each sacculus.
Yet, in the prior art that the open 2002-301019 communique of above-mentioned Japan patent is put down in writing,, yet can not control the gas supply flow of above-mentioned each sacculus although control in the sacculus of above-mentioned endoscope the air pressure in the sacculus with above-mentioned trocar sheath.And, in said apparatus, have following problem: can not to measure in order controlling the gas supply flow or the air feed of above-mentioned each sacculus to be pressed needed service life or inspiratory duration to above-mentioned each sacculus.
Summary of the invention
The present invention In view of the foregoing makes, and the purpose of this invention is to provide air feed or the endoscope balloon control device of inspiratory duration of the sacculus of measurable sacculus and trocar sheath to endoscope.
In order to achieve the above object, endoscope balloon control device of the present invention has: pump, and it is to being installed in the fixing sacculus supply gas of use that makes endoscope insert the leading section peripheral part of logical trocar sheath, and from above-mentioned sacculus discharge above-mentioned gas; Time detecting portion, it detects air feed and inspiratory duration to above-mentioned sacculus; Control part, the gas pressure that it is measured in the above-mentioned sacculus moves said pump according to this mensuration result and controls; Make when air feed, if the pressure in the above-mentioned sacculus then stops said pump greater than predefined upper limit force value; When air-breathing, if the pressure in the above-mentioned sacculus then stops said pump less than predefined threshold pression value; And, control the pressure in the above-mentioned sacculus according to the testing result of above-mentioned time detecting portion, make when above-mentioned air feed; If above-mentioned service life has surpassed predefined maximum service life, then stop said pump, above-mentioned when air-breathing; If above-mentioned inspiratory duration has surpassed the predefined maximum inhale time, then stop said pump; And flow backwards and to prevent use case, it has the case that above-mentioned sacculus is used, and through the control of above-mentioned control part, to above-mentioned sacculus gas is provided via said pump, and the case that above-mentioned sacculus is used constitutes that possessing flows backwards prevents locking mechanism, in case the refluence of solution stopping body.
