Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of puncture trocar sealing gasket.
Background technology
In Wicresoft's medical-therapeutic treatment of human body operation, once find focus in body, need operation or excision, in operation process, what first need application is perforator, perforator is a kind ofly to pierce through stomach wall and for other operating theater instruments provide the operating theater instruments that enters body cavity passage, belong to a kind of Minimally Invasive Surgery apparatus.Perforator generally includes as the sleeve assembly of other operating theater instruments admission passages with through the puncturing lever in described sleeve assembly.First, for transdermal, first with scalpel, cut epiderm skin, then utilize puncturing lever transdermal and enter body cavity together with sleeve assembly, then extract puncturing lever out, sleeve assembly just can be used as various apparatuses and instrument is introduced intraperitoneal and provide aeration to make stomach wall be elevated to the passage of organ top, intraperitoneal Leakage Gas when preventing that various apparatuses and instrument insert abdominal cavity in operation process, need on the mount pad in sleeve assembly, the sealing gasket that a plurality of braiding shapes distribute be set, during use, apparatus is through the black box center being comprised of a plurality of sealing gaskets, thereby reach the effect of sealing.But the sealing gasket of the perforator sleeve assembly often having exists many deficiencies, for example, install firmly not, in use, due to the passing by force of apparatus, sealing gasket is easily torn, and easily from mount pad, departs from, and sealing is poor, and gas leak phenomenon easily occurs.
The problem existing in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of multi-functional outer sealing device [application number: 201310204885.2] that is exclusively used in medical operating perforator, comprise upper press cover, lower cover, base, supporting seat, footstock, sealing membrane modules, support chip assembly and sealing gasket assembly, upper press cover and lower cover are fixed, sealing membrane modules is arranged between base and supporting seat, support chip assembly is arranged between supporting seat and sealing gasket assembly, and sealing gasket assembly is arranged between support chip assembly and footstock; Base, supporting seat, footstock, sealing membrane modules, support chip assembly and sealing gasket assembly are arranged in upper press cover and lower cover, and sealing gasket assembly and lower cover are fixed.
Such scheme has solved the poor problem of sealing gasket sealing effectiveness in existing perforator to a certain extent, but this scheme still exists: inconvenience is installed, and structural strength is low, in use passing by force due to apparatus, sealing gasket is easily torn, easily from problems such as mount pad depart from.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple in structure, the puncture trocar sealing gasket of good sealing effect during use.
For achieving the above object, this utility model has adopted following technical proposal: this puncture trocar sealing gasket, comprise the sealing of making and be half-conical tubular by flexible sheet material, it is characterized in that, the bottom of described sealing be provided with that side is horizontally outward extended and with the be connected as a single entity installation shirt rim of formula of sealing, the two ends that described installation shirt rim is circular arc and installation shirt rim exceed respectively both sides, sealing bottom and form the protrusion sheet that is symmetricly set on sealing both sides, the outer end of described protrusion sheet is triangular in shape, the top of described sealing is provided with arc gap, and described arc gap is towards the middle part of two tabs.This structure, arranges by some sealing gasket circumferential misalignment, thereby surround, is conical, good sealing effect during use, and arc gap can prevent the damage of sealing top.
In above-mentioned puncture trocar sealing gasket, the size that described sealing is projected in the central angle of conical bottom surface is 170 °-180 °.
In above-mentioned puncture trocar sealing gasket, described sealing is provided with enhancement Layer.
In above-mentioned puncture trocar sealing gasket, described installation shirt rim be provided with some in circular arc direction equally distributed installing hole, and the circumferential edge of described installation shirt rim and the outside that is positioned at installing hole are provided with at least one arc convex.Arc convex has the effect of reinforcement, and when apparatus is passed, sealing gasket is difficult for departing from from mount pad.
In above-mentioned puncture trocar sealing gasket, the quantity of described arc convex is one, and described arc convex is arranged on the end of protrusion sheet and is positioned at installation shirt rim away from the one side of sealing.While making a plurality of sealing gasket stack, arc convex can circumferentially be uniformly distributed.
In above-mentioned puncture trocar sealing gasket, the height of described arc convex for install shirt rim the thick end 2-4 doubly, and described arc convex with shirt rim be installed be connected as a single entity structure.Guaranteed that arc convex has enough intensity.
In above-mentioned puncture trocar sealing gasket, described installing hole comprises some installation macropores and aperture is installed, and described installation macropore with the aperture setting that is interspersed is one by one installed.
Compared with prior art, the advantage of this puncture trocar sealing gasket is: simple and reasonable, easy for installation, intensity is high, and stability is strong, is in use difficult for tearing, and is difficult for departing from from mount pad, and good sealing effect, is difficult for occurring gas leak phenomenon.
