Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3 and Fig. 4,1, a kind of negative-pressure double-sleeve drainage tube, including Trocar sheath 1 and drain inner sleeve 2, it is characterised in that: in internal section 3 of described trocar sheath 1 Sidewall is circumferentially uniformly distributed some raised lines 4, and the center of described raised line 4 has hole 5, The hole 5 of described raised line 4 and a passage 6 being arranged in external section of 7 sidewalls of trocar sheath 1 Converging connection, external section of 7 inwalls of described trocar sheath 1 are along the circumferential direction provided with a circle groove 8, In described groove 8, the input 31 of respective channel 6 arranges opening 9, and described opening 9 is with logical Road 6 connects, and the sidewall of internal section 11 of described drain inner sleeve 2 is uniformly arranged several sides Hole 12, is provided with in external section of 13 sidewalls of described drain inner sleeve 2 and connects with outside input thing Input thing passage 14, the outfan 15 of described input thing passage 14 is opened in drain inner sleeve 2 Lateral wall and position corresponding with groove 8, the inwall of described trocar sheath 1 is in the left and right of groove 8 Two side positions are in sealing contact with the outer wall of the correspondence position of drain inner sleeve 2, described drain inner sleeve The external end 16 of pipe 2 connects with negative pressure device.
Interpretation further optimizes for all parts of the present invention:
1, seeing Fig. 1, the middle part excircle of described drain inner sleeve 2 is provided with a circle inflatable ball Capsule 17, described inflating balloon 17 charges the maximum cross-section diameter after gas more than or equal to overcoat The internal diameter of pipe 1, described inflating balloon 17 and one are arranged in drain inner sleeve 2 sidewall Inlet channel 18 connects, and described inlet channel 18 is connected in drain from drain inner sleeve 2 sidewall The source of the gas 19 of sleeve pipe 2 external end 16 side, will isolate in trocar sheath after aerating gasbag 17 inflation One-tenth drainage lumens 39 and cleaning chamber 38, the i.e. body fluid of outer casing tube body inner segment will not be from drainage lumens 39 Flow back to clean chamber 38.
2, seeing Fig. 3, the input 20 of described input thing passage 14 uses three-way pipe structure, One input 21 of described input thing passage 14 and fluid connection, described input thing passage Another input 22 and atmosphere of 14, introducing gas is to serve Pressure behaviour in pipe Balanced action.
3, seeing Fig. 1, the end face of the internal end 23 of described trocar sheath 1 has central draft hole 24, the circumferential side wall of internal section 3 of described trocar sheath 1 has several side conduction holes 26, The side of the internal end 27 of described drain inner sleeve 2 is provided with time conduction hole 28, central draft hole The 24 internal body fluid of behaviour carry out drain, and time conduction hole 28 and side conduction hole 26 also function to simultaneously The effect of drain.
4, seeing Fig. 2, described trocar sheath 1, with centre position as boundary, is spelled by silica gel and rubber Connecing and form, external section 7 of trocar sheath 1 is silica gel, and internal section 3 of trocar sheath 1 is rubber.
5, the longitudinal section of the hole 5 of described raised line 4 is fan-shaped, outside sector structure enables to Portion's input thing overflows with sector format.
6, seeing Fig. 1, described trocar sheath 1 and drain inner sleeve 2 tube wall stringer are provided with metal Development bar, and scale marker.
7, seeing Fig. 1, described drain inner sleeve 2 is in the position of the left and right sides of respective slot 8 The place of putting is respectively equipped with a sealing block 29, and the present invention is here by sealing block, it is achieved in drain Sleeve pipe 2 is tightly connected with trocar sheath 1 groove 8, i.e. the outside input of input thing passage 14 Thing can only enter groove 8, then passes sequentially through opening 9 and enters into passage 6, then arrives The raised line 4 of trocar sheath 1, finally exports from the hole of raised line 4.
8, see Fig. 4, be provided with one in trocar sheath 1 for replacing dredging of drain inner sleeve 2 Logical inner sleeve 32, external section 33 of described dredging inner sleeve 32 is provided with a circle outside covering The covering sealing block 34 of the groove 8 of sleeve pipe 1, the outfan 35 of described dredging inner sleeve 32 Use unidirectional three-way pipe structure, of the outfan 35 of described dredging inner sleeve 32 time input End 36 and fluid connection, another two secondary input end 37 of described dredging inner sleeve 14 is with big Gas connects, and dredging inner sleeve is stretched in trocar sheath, it is ensured that do not move outer casing tube body intracavitary locations, Dredging inner sleeve is used simply, effectively to remove various such as blood clot, fragment of tissue and albumen Mix tamper.
The design principle of the present invention: negative pressure can be strengthened drain and promote that tissue centration is assembled Growing, this, after coeliac cavity internal organs generation fistula, is even more important, and drain inner sleeve is exactly this work Core;Trocar sheath then plays isolation, it is to avoid inner sleeve directly contacts internal organs, causes two Secondary damage and the situation such as hemorrhage.Details therein is: trocar sheath internal channel and internal hop count The design of raised line makes flushing liquid may be uniformly distributed in drain inner chamber so that drain is more logical Freely, efficiently;Inner sleeve one terminates negative pressure, and the other end is designed as unidirectional three-port structure so that liquid Body and gas can independently enter tube chamber, the pressure between dynamic equilibrium turnover thing, last one end Communicate with the air bag in the middle part of drain inner sleeve, after airbag aeration, isolation trocar sheath for cleaning chamber with And drainage lumens, it is to avoid retrograde infection.
Beneficial effects of the present invention: the positions, thoracic cavity such as lungs, heart, vertical diaphragm and gastrointestinal, Liver and gall, recurrence complexity infects the abdominal part such as hernia and stomach wall is postoperative, operation technique position or near list Solely indwelling trocar sheath, this trocar sheath can be considered general drainage pipe, and routine connects drainage bag.If going out The most such as a large amount of hydrops in thoracic cavity, abdominal cavity, hematocele, leak, intestinal fistula, fistula of operative incision, lacuna sense Dye, abscess;And because blood clot, histiocyte fragment and albumen mix tamper blocking overcoat Pipe, causes the most unobstructed, even in the case of plugging, it is ensured that do not move outer casing tube body intracavity position Put, simple, be efficiently used dredging inner sleeve remove various such as blood clots, fragment of tissue and Albumen mixes tamper, easily recovers adequate drainage, and method is as follows, connects negative by dredging inner sleeve After pressure, stretch in trocar sheath, after dredging inner sleeve head end contacts tamper, operator's thumb Close another opening opening at air, thus tamper is sucked out under suction function;Special In the case of as fistula drain inner sleeve can be used safe efficient actively draw passively upgrading to Stream, it is achieved optimal drainage effect is it is possible to avoid second operation, and method is as follows, by drain Inner sleeve inserts in trocar sheath, owing to the inwall of trocar sheath is in the left and right sides of groove and inner tube Correspondence position outer wall is in sealing contact, and the input thing of drain inner sleeve can only from input thing passage input Enter in groove, thus be input to outer casing tube body inner segment by the opening of the passage of outer sleeve inner wall Inwall fixes the hole of projection, and then drain inner sleeve is connected with negative pressure device, carries out negative pressure master Dynamic attraction drain, drain inner sleeve middle section position is provided with inflating balloon simultaneously, and inflating balloon exists After inflation, the inner chamber of trocar sheath is isolated into drainage lumens and cleaning chamber, i.e. in drainage lumens Mixing dirt will not flow backwards and be accumulated in cleaning chamber, thus avoid endoceliac retrograde infection
