Abstract
The invention provides a sealing part of a puncture outfit. The sealing part comprises a floating airtight portion and a static airtight portion which are fixedly connected mutually. The floating airtight portion comprises at least one drape portion and a through hole arranged at center of the drape portion. The static airtight portion comprises at least one duckbilled airtight valve, and the front end of the duckbilled airtight valve is a sealing nozzle for keeping sealing under air pressure. The sealing part has the advantages that a structure is simple, the whole sealing part is conveniently connected with the puncture outfit, and a puncture outfit body is simplified in structure.
Description
Technical field
The present invention relates to a kind of perforator, relate in particular to a kind of new type sealing element for perforator.
Background technology
Later 1980s, the advantage of comparing tradition (open) operation along with laparoscopic cholecystectomy becomes day by day obvious, and laparoscopically surgical operation comes into vogue.The advantage that laparoscopic surgery is generally acknowledged is rehabilitation duration after desmopyknosis, significantly alleviates postoperative pain and wound infection and improve appearance, and this is mainly can utilize the less otch of body lumen wall and carry out operation due to laparoscopic surgeon.
Many laparoscopic surgeries relate to by to Intraperitoneal injection CO
2Gas makes pressure reach about 15mm Hg, increases and carries out operating inner space.Pierce through abdominal wall, then insert perforator in the abdominal cavity, for example US Patent No. 5628732 discloses.Perforator is a kind ofly to pierce through stomach wall and for other shell operating theater instruments provide the operating theater instruments that enters the body cavity passage, belong to a kind of Minimally Invasive Surgery apparatus.Perforator must be with respect to outside seal, so that in a single day it be placed in and just can complete gas injection in tissue and with its maintenance.Therefore, multiple potted component is used in perforator, so that before surgical operating instrument inserts and afterwards with its service aisle sealing.
At present, perforator uses a kind of " duckbill " black box usually.A kind of " duckbill " black box is disclosed as Chinese patent CN200410092185, comprise a pair of relative valve member, it is closed when being subject to intra-abdominal pressure, specifically comprise: seal, be suitable for mobile optionally to open and to close fully described black box, described black box is included in the longitudinal axis that wherein extends, and the described longitudinal axis is with vertical with it transverse plane; Described seal comprises a near-end and a far-end, and described near-end forms the first angle with respect to described transverse plane, and described far-end forms the second angle with respect to described transverse plane, described the first angle less than the second angle and described the second angle less than 90 degree.
After the sleeve assembly of perforator entered body cavity, due to the effect of abdominal pressure, it was sealing state that " duckbill " black box keeps closing; When having medical apparatus and instruments to be undertaken operating in body cavity by sleeve assembly, " duckbill " thus black box is subject to the thrust sector of medical apparatus and instruments to be opened and allows medical apparatus and instruments to pass through.
Because " duckbill " black box of prior art can only be with its service aisle sealing before surgical operating instrument inserts, so generally also need separately to establish a potted component, the surgical operating instrument insertion also can be sealed its service aisle afterwards, and 2 road potted components are individually fixed on the fixture that connects separately, when having cut organization need to be taken out, aforementioned two fixtures need separate, and make tissue can pass " duckbill " black box and are taken out.Like this also can show slightly trouble in assembling and Element Design.
The present invention quotes the content that this patent is put down in writing as prior art.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of novel puncture device sealing member simple in structure.
Purpose of the present invention will be achieved by the following technical programs:
A kind of sealing member for puncture outfit, comprise unsteady airtight and Static Gas compact part being mutually permanently connected, the described airtight section of floating comprises that at least a pleated portions and is placed in the through hole of described pleated portions central authorities, described Static Gas compact part comprises a duckbilled airtight valve at least, and the front end of described duckbilled airtight valve is to keep the sealed mouth of sealing when gas pressure is arranged.
Preferably, described outermost of floating airtight section is the broadside that is connected with described pleated portions, and described floating airtight fixed by syndeton and the described Static Gas compact part be located on described broadside.
Preferably, described floating airtight is connected an Access Division with the Static Gas compact part and connected.
Preferably, described Static Gas compact part comprises the annular flange that equates with the external diameter of the broadside of the described airtight section of floating, and described annular flange is provided with the extension, and the front end of described extension is the duckbilled airtight valve.
Preferably, described duckbilled airtight valve is two lobe formulas or fFour piece type structure.
Beneficial effect of the present invention is mainly reflected in: simple in structure, whole easy to connect with perforator, and perforator itself is also simplified the structure.

The specific embodiment
The first embodiment as shown in Figure 1 the invention provides a kind of novel puncture device sealing member 10, comprises unsteady airtight 1 and Static Gas compact part 2 being mutually permanently connected.
In conjunction with Fig. 2 and shown in Figure 3, described floating comprises that at least a pleated portions 12 and is placed in the through hole 13 of described pleated portions 12 central authorities for airtight 1, and described outermost of floating airtight section is the broadside 11 that is connected with described pleated portions 13.
Described Static Gas compact part 2 comprises the annular flange 21 that equates with the external diameter of the broadside 11 of the described airtight section of floating, described annular flange 21 is provided with extension 22, the front end of described extension 22 is duckbilled airtight valve 23, and the front end of described duckbilled airtight valve 23 is to keep the sealed mouth 24 of sealing when gas pressure is arranged.
Described floating fixed by syndeton and the described Static Gas compact part 2 be located on described broadside 11 for airtight 1.Preferably, described floating airtight is connected an Access Division 3 and connected with the Static Gas compact part.Certainly the connected mode of not getting rid of other, for example bonding, ultrasonic bonding etc.
In the present embodiment, described duckbilled airtight valve is two lobe formula structures.Fig. 4-the second embodiment shown in Figure 6 and the difference of the first embodiment are that described duckbilled airtight valve is the fFour piece type structure.
Before surgical operating instrument inserted described perforator, Static Gas compact part 2 was with its service aisle sealing; After surgical operating instrument inserts described perforator, namely by the through hole 13 of described unsteady airtight 1, float airtight 1 with its service aisle sealing.In the time need to taking out cut organizing from the passage of perforator, described hermetically-sealed construction integral body can be removed, after then tissue takes out, more rapidly described hermetically-sealed construction is installed back original position.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
