Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of this utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, term " on ", D score, " top ", " bottom ", the orientation of the instruction such as " longitudinal direction " or state relation be based on orientation shown in the drawings or state relation, only this utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in this utility model can be understood.
This utility model embodiment provides a kind of inserter, it is a kind of auxiliary device fujinon electronic video endoscope is placed to along digestive tract in biliary tract, this inserter comprises flexible pipe 1, seal wire 2 and anchoring 3, the front end of flexible pipe has outlet, fujinon electronic video endoscope is inserted into the front end of flexible pipe 1, and is leant out by the front end of flexible pipe and observe sufferer; It should be noted that this inserter and be incessantly confined to be implanted into fujinon electronic video endoscope to biliary tract, can also be placed in other organs of human body by other equipment to be inserted.
The sidewall of the front end near described flexible pipe 1 is provided with opening 13; Described seal wire 2 part is located in described flexible pipe 1, and the front end of described seal wire 2 is passed by described opening 13 and is connected with the front end of described flexible pipe 1; Described anchoring 3 is arranged on the rear end of described flexible pipe 1, and is connected with the rear end of described seal wire 2, for pulling described seal wire 2.When driving anchoring 3 to pull seal wire 2, seal wire 2 moves backward in flexible pipe 1, the seal wire 2 passing described opening 13 is returned in flexible pipe 1 gradually, namely the distance wearing out the seal wire 2 of described opening 13 shortens gradually, this forces the pipeline section be positioned at before opening 13 to bend, the front end of flexible pipe 1 bends to the side of opening 13, makes the front end of flexible pipe 1 that the change of angle occur, realizes thus fujinon electronic video endoscope is manipulated according to certain angle.
The structure of described anchoring 3 comprises rotating shaft 31 and knob 32; Described rotating shaft 31 is arranged on the rear end of described flexible pipe 1, and be provided with the first through hole laterally running through both sides sidewall in the rear end of flexible pipe 1, rotating shaft 31 is located in this first through hole rotationally; Described knob 32 is connected to one end of rotating shaft 31, rotates for driving described rotating shaft 31; Seal wire 2 volume, in described rotating shaft 31, when rotating shaft 31 rotates, can be set in rotating shaft 31 by the rear end solderless wrapped connection of described seal wire 2.Thus, the pulling to seal wire 2 can be realized by turning knob 32.
Knob 32 entirety, in gear-like, is circumferentially with multiple turning gear, the convenient rotation to knob 32.Anchoring 3 also comprises spacer pin 33 in addition, in the rear end of flexible pipe 1, and the rear being positioned at described first through hole is provided with the second through hole laterally running through both sides sidewall, described spacer pin 33 is telescopic to be located in described second through hole, described spacer pin 33 is positioned at the side of described knob 32, the axial location of spacer pin 33 is between the tooth top and tooth root of described knob 32, and namely spacer pin 33 can be located between two turning gears.Spacer pin 33 is for being formed the circumference of described knob 32 spacing with turning gear snap-fit engagement, when making the front end of flexible pipe 1 reach predetermined angular to the manipulation of knob 32, control spacer pin 33 to stretch out to the side of knob 32, be plugged between two turning gears on knob 32 under corresponding orientation, spacing circumferentially to knob-shaped, can prevent turning gear from being retracted by seal wire 2 under the effect of flexible pipe 1 runback power thus.
The interior separation of described flexible pipe 1 is formed with silk guide passage 11 and inserts passage 12, silk guide passage 11 and insert all respective side along flexible pipe 1 of passage 12 and extend; Described silk guide passage 11 is for wearing described seal wire 2; Described passage 12 of inserting is for passing into fujinon electronic video endoscope, and silk guide passage 11 and insert passage 12 and seal wire 2 can be separated with fujinon electronic video endoscope, does not form interference both making each other.
The sidewall of described flexible pipe 1 be provided with described insert that passage 12 is communicated with insert pipe 4, inserting pipe 4 is the manifold extended along the side of flexible pipe 1, insert pipe 4 preferably to tilt to the rear end of described flexible pipe 1, after the front end of flexible pipe 1 is inserted into assigned address, fujinon electronic video endoscope can be inserted into insert in passage 12 along insert pipe 4, until fujinon electronic video endoscope to be sent to the front end of flexible pipe 1, finally leant out by the outlet of the front end inserting passage, carry out the observation of the state of an illness in gallbladder.
Preferably, the tube wall of described flexible pipe 1 is axially arranged with the rib of multiple tracks projection, many ribs circumference on the tube wall of flexible pipe 1 is uniformly distributed, the rib arranged vertically can strengthen the runback ability of flexible pipe 1, when oppositely going back to knob 32, the front end of flexible pipe 1 is formed seal wire 2 and pulls under the effect of runback power, thus can utilize the double-direction control of runback power realization to the angle of flexible pipe 1 front end of knob 32 and flexible pipe 1 front end.
In addition, rib also can strengthen the anti-torsional strength of flexible pipe 1, thus, by reversing the rear end of flexible pipe 1, the leading portion of flexible pipe 1 also twists thereupon, thus the direction of opening 13 is also changed, namely convertible flexible pipe 1 front end towards, thus realize the comprehensive observation of fujinon electronic video endoscope.Described rib is preferably arranged on the inwall of described flexible pipe 1, does not affect the flatness of outer wall.
Described flexible pipe 1 be provided with scale, scale is the interval that a series of line or point section out, and is used for metering flexible pipe 1 to insert gastral distance, and this inserter structure is simple, and easy to operate, cost is low, is suitable for promoting the use of as medical disposable material.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
