Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of sleeve puncture outfit.
Background technology
Sleeve puncture outfit is a kind of surgical operating instrument, and its main uses is to carry gas for the backward intraperitoneal in the abdominal cavity of puncturing in laparoscopic surgery, and as the passage in endoscope and operating theater instruments turnover abdominal cavity.
Sleeve puncture outfit mainly comprises sleeve pipe and perforator two parts, and both cooperation realize its puncture function.During operation, when perforator enters in the sleeve pipe being retained in stomach wall, sealing due to sleeve pipe, Intraabdominal air pressure is kept, yet the sleeve pipe in sleeve puncture outfit only contains a sealing ring in the market, easily cause gas leakage, and it can only be used in conjunction with a kind of apparatus of dimensions.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sleeve puncture outfit that contains multi-sealing structure, and this sleeve puncture outfit can also be used in conjunction with the apparatus of sizes specification.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is:
A kind of sleeve puncture outfit, comprise sleeve pipe and perforator, described perforator is divided into top and point, described perforator point inserts in described sleeve pipe, between described top and described sleeve pipe, be provided with cover plate, the first black box, gland and the second black box, described cover plate, the first black box, gland and the second black box are fixedly connected sequentially and are all fixed on described sleeve pipe, the lower edge at described perforator top is provided with projection, the top of described cover plate is provided with hole, and described projection cooperatively interacts and is connected with hole.
As preferably, described the first black box is connected to form successively by upper tabletting, the first sealing ring, the second sealing ring, the 3rd sealing ring and lower sheeting.
As preferably, described the 3rd sealing ring is divided into interior annulus and outer toroid two parts, is equipped with 2 or 2 above fixing holes in interior annulus and outer toroid.
As preferably, described upper tabletting is provided with 2 or 2 above Kong Zhu, on described the first sealing ring, the second sealing ring and lower sheeting, be equipped with the fixing hole matching with upper tabletting hole post, the number of described the first sealing ring, the second sealing ring and fixing hole on lower sheeting is consistent with the number of Kong Zhu on upper tabletting.
Beneficial effect: compare the single hermetically-sealed construction with prior art middle sleeve perforator, sleeve puncture outfit of the present invention adopts multi-sealing structure, add the uniqueness of every this body structure of resealing structure, thereby not only can make perforator or apparatus turnover sleeve pipe there is no very large resistance, can make again black box be close to perforator or apparatus, air pressure in operation process midfield is not revealed, and sleeve puncture outfit of the present invention can also be used in conjunction with the apparatus of sizes specification simultaneously.

The specific embodiment
According to following embodiment, the present invention may be better understood.Yet, those skilled in the art will readily understand, the described content of embodiment is only for the present invention is described, and should also can not limit the present invention described in detail in claims.
As shown in Fig. 1～10, a kind of sleeve puncture outfit, comprise sleeve pipe 24 and perforator 18, described perforator 18 is divided into top 21 and point 20, described perforator 18 points 20 insert in described sleeve pipe 24, between described top 21 and described sleeve pipe 24, be provided with cover plate 16, the first black box 22, gland 14 and the second black box 23, described cover plate 16, the first black box 22, gland 14 and the second black box 23 are fixedly connected sequentially and are all fixed on described sleeve pipe 24, the lower edge at described perforator 18 tops 21 is provided with anti-skidding protruding 19, the top of cover plate 16 is provided with anti-slide opening 17, anti-skidding protruding 19 cooperatively interact and are connected with anti-slide opening 17, this anti-skid structure can prevent when puncture perforator 18 and sleeve pipe 24 between mutual slip, and then raising puncture efficiency.
The first black box 22 is connected to form successively by upper tabletting 10, the first sealing ring 1, the second sealing ring 4, the 3rd sealing ring 7 and lower sheeting 12.The first sealing ring 1 adopts silicone rubber or elastomeric material (TPE or TPU) to make, adopt the first sealing ring 1 that this material is made not only can protect assembly to be below difficult for being punctured, and then play the effect of enhanced leaktightness, but also the intensity that can improve whole sealing system makes it be difficult for the apparatus crimp or the reversion that are passed in and out, the second sealing ring 4 adopts silicone rubber material to make, and surrounding is annular, because the second sealing ring 4 is by good scalability, can allow any apparatus larger than they apertures own pass through, the 3rd sealing ring 7 adopts silicone rubber to make, it is divided into interior annulus and outer toroid two parts, in interior annulus and outer toroid, be equipped with 2 or 2 above fixing holes, in the middle of interior annulus and outer toroid, be provided with V font fold in addition, fold number is more than 1 or 1, V-type fold can easily be stretched under external force, the first black box 22 can horizontal direction be free to slide with gland 14 is middle at cover plate 16, the hole post 11 of upper tabletting 10 is by the fixing hole 2 of the first sealing ring 1, the fixing hole 5 of the second sealing ring 4, the fixing hole 9 of the interior annulus of the 3rd sealing ring 7 links together the first black box 22, finally the fixing hole 13 by lower sheeting 12 compresses.
