Abstract
The invention discloses a floating sealing assembly which comprises a sealing upper cover and a sealing lower cover which are mutually fixed. A sealing device is arranged in a containing space formed by the sealing upper cover and the sealing lower cover. The sealing device comprises an upper fixed ring, a sealing ring and a lower fixed ring which are mutually matched in a close mode, a round hole for an instrument to pass through is arranged on the sealing ring, and at least two elastic strips are connected between the sealing device, the sealing upper cover and/ or the sealing lower cover. The floating sealing assembly has the advantages of being simple in structure, good in sealing effect and low in cost.
Description
Technical field
The present invention relates to a kind of perforator, relate in particular to a kind of floating seal modular construction of perforator.
Background technology
Perforator is a kind ofly to pierce through stomach wall and the operating theater instruments that enters the body cavity passage is provided for other operating theater instruments, belongs to a kind of Minimally Invasive Surgery apparatus.Perforator generally includes as the sleeve assembly of other operating theater instruments admission passages and the puncturing lever in the described sleeve assembly.For transdermal, first cut epiderm skin with scalpel, then puncturing lever transdermal and enter body cavity; By exerting pressure to described puncturing lever, and the tip that promotes described puncturing lever passes skin, until puncturing lever and sleeve assembly all enter body cavity; Then, extract puncturing lever out, sleeve assembly just can be used as the mis instruments passage of carrying out endo-surgical and splanchnoscopy operation.
At present, perforator uses a kind of floating seal usually, and this floating seal can be surrounded on the operating theater instruments that is inserted in described sleeve assembly, thereby stops fluid and be blown into endoceliac gas by described sleeve assembly.As shown in Chinese patent CN200510130187.8, floating seal comprises: a plurality of diaphragm seals, each diaphragm seal comprises neighboring and a seam edge of an arc, each diaphragm seal also comprises a horn shape part of extending, this horn shape partly has the shape and size that can be connected with adjacent diaphragm seal, wherein said horn shape is partly for taper, with being connected of convenient and adjacent seals sheet; At least the first diaphragm seal and the second diaphragm seal link together along their neighboring separately, and to form jointed the first sealant of a tool, this seam is limited by the seam edge of the first diaphragm seal and the seam edge of the second diaphragm seal; At least one the 3rd diaphragm seal and one the 4th diaphragm seal link together along their neighboring separately, and to form jointed the second sealant of a tool, this seam is limited by the seam edge of the 3rd diaphragm seal and the seam edge of the 4th diaphragm seal; Wherein the seam of the first sealant has the first longitudinal axis, and the seam of the second sealant has the second longitudinal axis, and the first longitudinal axis becomes angle directed with respect to the second longitudinal axis.
When puncturing lever or other apparatuses during by sleeve assembly, floating seal is opened and the surface of puncturing lever or other apparatuses is sealed.But the floating seal preparation technology more complicated of prior art is difficult to reach the effect of sealing.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of perforator floating seal assembly simple in structure.
Purpose of the present invention will be achieved by the following technical programs:
A kind of floating seal assembly, comprise the sealing upper cover and the sealing lower cover that interfix, described by being provided with a sealing device in sealing upper cover and the receiving space that forms of sealing lower cover, described sealing device comprises upper retainer ring, sealing ring, the lower retainer ring that mutually is tightly fixed successively, described sealing ring is provided with the circular hole that can supply apparatus to pass through, and is connected with at least two elastic strips between described sealing device and sealing upper cover and/or sealing lower cover.
Preferably, described elastic strip extends the periphery that is arranged at described sealing ring.
Preferably, the periphery of described sealing ring is provided with 4 symmetrical elastic strips.
Preferably, the far-end of described elastic strip is provided with annular ring, convexes with locating dowel on described sealing lower cover, and annular ring is sheathed on described locating dowel.
Preferably, described sealing ring, elastic strip and annular ring are integrally manufactured.
Preferably, the fixed ring is provided be used to the opening that described elastic strip is passed through.
Preferably, be buckle structure between described sealing upper cover and sealing lower cover.
Beneficial effect of the present invention is mainly reflected in: simple in structure, and good sealing effect, cost is low.
Description of drawings
Fig. 1 is the exploded perspective view of floating seal assembly of the present invention.
Fig. 2 is the cutaway view of floating seal assembly of the present invention.
The specific embodiment
As shown in Fig. 1-2, the invention provides a kind of floating seal assembly of perforator, comprise the sealing upper cover 1 and the sealing lower cover 5 that interfix.Preferably, be buckle structure between described sealing upper cover 1 and sealing lower cover 5, in this preferred embodiment, sealing upper cover 1 is provided with buckle 11, and is corresponding, and sealing lower cover 5 is provided with through hole 51.
Be provided with a sealing device in the described receiving space that is formed by sealing upper cover 1 and sealing lower cover 5, described sealing device comprises upper retainer ring 2, sealing ring 3, the lower retainer ring 4 that mutually is tightly fixed successively, and described sealing ring 3 is provided with the circular hole 31 that can supply medical apparatus and instruments to pass through.In this preferred embodiment, upper retainer ring 2 and sealing ring 3 include the space of an indent, play the guiding medical apparatus and instruments and pass through smoothly the effect of circular hole 31.Sealing ring 3 is also elastomeric material, and circular hole 31 can pass through for the different-diameter medical apparatus and instruments in its regime of elastic deformation.The periphery of sealing ring 3 and upper retainer ring 2 interference fit, the periphery of lower retainer ring 4 and sealing ring 3 interference fit, like this, sealing fully between upper retainer ring 2, sealing ring 3, lower retainer ring 4 threes.
In this preferred embodiment, the periphery of described sealing ring 3 is provided with 4 symmetrical elastic strips 32.Described elastic strip 32 extends the periphery that is arranged at described sealing ring 3.The far-end of described elastic strip 32 is provided with annular ring 33, convexes with locating dowel 53 on described sealing lower cover 5, and annular ring 33 is sheathed on described locating dowel 53.Preferably, described sealing ring 3, elastic strip 32 and annular ring 33 are integrally manufactured, are all namely that elastomeric material makes, rubber strip for example, and existing sealing function is flexible function again.When institute's medical apparatus and instruments passes through described sealing ring 3, because operation demand, apparatus can swing with sealing ring, because the strain that elastic strip is good, can make sealing ring follow medical apparatus and instruments to swing, but the place that sealing ring contacts with apparatus keeps close contact with apparatus all the time, realizes good airtight effect.Also be provided with on fixed ring 2 be used to the opening 22 that described elastic strip 32 is passed through, guarantee that like this elastic strip can stretch from the space of the indent of upper retainer ring 2.
The present invention when medical apparatus and instruments swings after the circular hole 31 that passes sealing ring, floats by the pulling force effect realization of elastic strip 32 and waves in use, guarantees airtight.
The present invention still has numerous embodiments; for example cover in the sealing and be provided with locating dowel; the elastic strip of described sealing device namely is connected with the sealing upper cover, and all employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
