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 puncture outfit, particularly relate to a kind of floating seal modular construction of puncture outfit.
Background technology
Puncture outfit a kind ofly pierces through stomach wall and provide the operating theater instruments entering lumenal passageway for other operating theater instruments, belongs to a kind of Minimally Invasive Surgery apparatus.Puncture outfit generally includes as the sleeve assembly of other operating theater instruments admission passages with through the puncturing lever in described sleeve assembly.In order to transdermal, first cut epiderm skin with scalpel, then puncturing lever transdermal enter body cavity; By applying pressure to described puncturing lever, and promote the tip of described puncturing lever through skin, until puncturing lever and sleeve assembly all enter body cavity; Then, extract puncturing lever out, sleeve assembly just can as the mis instruments passage performing endo-surgical and endoscopy operation.
At present, puncture outfit uses a kind of floating seal usually, and this floating seal can be surrounded on the operating theater instruments be inserted in described sleeve assembly, thus stops fluid and be blown into endoceliac gas by described sleeve assembly.As shown in Chinese patent CN200510130187.8, floating seal comprises: multiple diaphragm seal, each diaphragm seal comprises neighboring and a seam edge of an arc, each diaphragm seal also comprises the angled section of an extension, this angled section has the shape and size that can be connected with adjacent diaphragm seal, wherein said angled section is taper, to facilitate the connection with adjacent seals sheet; At least the first diaphragm seal and the second diaphragm seal link together along their respective neighboring, and to form jointed 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 3rd diaphragm seal and one the 4th diaphragm seal link together along their respective neighboring, and to form jointed 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 relative to the second longitudinal axis.
When puncturing lever or other apparatuses are by sleeve assembly, floating seal is opened and seals the surface of puncturing lever or other apparatuses.But the floating seal preparation technology more complicated of prior art, is difficult to the effect reaching sealing.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of structure simple puncture outfit floating seal assembly.
Object of the present invention, will be achieved by the following technical programs:
A kind of floating seal assembly, comprise the sealing upper cover and sealing lower cover that interfix, a sealing device is provided with in the described receiving space formed by sealing upper cover and sealing lower cover, described sealing device comprises the upper retainer ring, sealing ring, the lower retainer ring that are mutually tightly fixed successively, described sealing ring is provided with the circular hole that can pass through for apparatus, described sealing device and sealing upper cover and/or seal between lower cover and be connected with at least two elastic strips.
Preferably, described elastic strip is extended in the periphery of 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, and described sealing lower cover is convexly equipped with locating dowel, and annular ring is sheathed in described locating dowel.
Preferably, described sealing ring, elastic strip and annular ring are integrally manufactured.
Preferably, fixed ring is provided with the opening for making described elastic strip pass through.
Preferably, be buckle structure between described sealing upper cover and sealing lower cover.
Beneficial effect of the present invention is mainly reflected in: structure is simple, and good sealing effect, cost is low.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view of floating seal assembly of the present invention.
Fig. 2 is the sectional view of floating seal assembly of the present invention.
Detailed description of the invention
As shown in Figure 1-2, the invention provides a kind of floating seal assembly of puncture outfit, comprise the sealing upper cover 1 and sealing lower cover 5 that interfix.Preferably, be buckle structure, seal upper cover 1 and be provided with buckle 11 in this preferred embodiment between described sealing upper cover 1 and sealing lower cover 5, accordingly, sealing lower cover 5 is provided with through hole 51.
A sealing device is provided with in the described receiving space formed by sealing upper cover 1 and sealing lower cover 5, described sealing device comprises the upper retainer ring 2, sealing ring 3, the lower retainer ring 4 that are mutually tightly fixed successively, and described sealing ring 3 is provided with the circular hole 31 that can pass through for medicine equipment.In this preferred embodiment, upper retainer ring 2 and sealing ring 3 include the space of an indent, play and guide medicine equipment smoothly by the effect of circular hole 31.Sealing ring 3 is also elastomeric material, and circular hole 31 can pass through for different-diameter medicine equipment 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, seal between upper retainer ring 2, sealing ring 3, lower retainer ring 4 three completely.
In this preferred embodiment, the periphery of described sealing ring 3 is provided with 4 symmetrical elastic strips 32.Described elastic strip 32 is extended in the periphery of described sealing ring 3.The far-end of described elastic strip 32 is provided with annular ring 33, and described sealing lower cover 5 is convexly equipped with locating dowel 53, and annular ring 33 is sheathed in described locating dowel 53.Preferably, described sealing ring 3, elastic strip 32 and annular ring 33 are integrally manufactured, and be namely all that elastomeric material obtains, such as rubber strip, existing sealing function is flexible function again.When institute's medicine equipment is by described sealing ring 3, because operation demand, apparatus can swing with sealing ring, because the elastic deformation that elastic strip is good, sealing ring can be made to follow medicine equipment to swing, but the place of sealing ring and device contacts keeps close contact with apparatus all the time, realize good airtight effect.Fixed ring 2 being also provided with the opening 22 for making described elastic strip 32 pass through, ensureing that elastic strip can be stretched from the space of the indent of upper retainer ring 2 like this.
The present invention in use, when medicine equipment swings after the circular hole 31 passing sealing ring, realizes floating by the pulling force effect of elastic strip 32 and waves, ensure airtight.
The present invention still has numerous embodiments; such as sealing covers and be provided with locating dowel; namely the elastic strip of described sealing device is connected with sealing upper cover, all employing equivalents or equivalent transformation and all technical schemes of being formed, all drops within protection scope of the present invention.
