The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.
As Figure 1-5, a kind of stent in esophagus with visual function is placed withdrawing device, comprises trocar sheath 5 and inner sleeve 4, and the upper end of described trocar sheath 5 and inner sleeve 4 is provided with horn-like handle 6; Described inner sleeve 4 lower end outer walls are provided with latex ring 3, and inner chamber has the bar 7 of placement to pass; Described placement bar 7 upper ends are provided with sample pickup tongs 2 and place, take out joystick, and lower end is provided with sample pickup tongs 2; Described sample pickup tongs 2 is divided into left binding clip 14 and right binding clip 8; Described right binding clip 8 belows are provided with minisize pick-up head 10 and miniature LED lamp 11, and minisize pick-up head 10 is connected with power supply with display by optic fibre wire 12 respectively with miniature LED lamp 11.
Embodiment 1
Ultimum Ti stent in esophagus routine is placed, taking-up surgical operation step is as follows:
1) as shown in Figure 2, first inner sleeve 4 is inserted in trocar sheath 5, allow and expose from trocar sheath 5 with one end of latex ring 3, the upper end of Ultimum Ti stent in esophagus 1 freezing after shrinking is enclosed within on the latex ring 3 of inner sleeve 4 lower end outer walls, again Ultimum Ti stent in esophagus 1 is together filled among trocar sheath 5 together with latex ring 3, the horn-like handle 6 of then pulling back on inner sleeve 4, latex ring 3 traction Ultimum Ti stent in esophagus 1 all enter among trocar sheath 5 standby;
2) as Figure 1-5, during use, minisize pick-up head 10 is connected with power supply with display by optic fibre wire 12 respectively with miniature LED lamp 11, utilizes and places the outside graduation mark display scale of bar 7, can be used as esophagus measuring device and uses; Measure complete, select correct stent in esophagus model, under the supervision of minisize pick-up head 10, the placement withdrawing device that Ultimum Ti stent in esophagus is housed is sent Ultimum Ti stent in esophagus 1 into esophagostenosis position from patient oral cavity, then with the latex ring 3 on inner sleeve 4 lower end outer walls, Ultimum Ti stent in esophagus 1 is released from trocar sheath 5.Ultimum Ti stent in esophagus 1 is left after trocar sheath 5, and the bulk expansion of being heated is returned freezing front shape esophagostenosis place is strutted, and extracts trocar sheath 5 and inner sleeve 4, and it is complete that Ultimum Ti stent in esophagus is laid operation.While implementing to take out stent in esophagus, this utility model is inserted in esophagus, turn on minisize pick-up head 10 and miniature LED lamp 11 makes its work, illuminate esophagus, in the situation that having illumination, on display, observed the position of stent in esophagus like this, sample pickup tongs 2 is vised to the tight mouth of metallization annular line 1-1 from middle insertion of trocar sheath 5, be drawn among trocar sheath 5, then extracted trocar sheath 5, taken out Ultimum Ti stent in esophagus 1.Avoided, in blind all drawbacks depending on by virtue of experience performing the operation with sense of touch under state, greatly having increased safety, suitability and the effectiveness of placing stent in esophagus operation, reduced operation receiveing person's painful and worry, reduced medical personnel's labor intensity.
