Abstract
The invention provides a high-elasticity channel valve. The high-elasticity channel valve is characterized in that a crack film and a hole film are arranged in a shell, a tightening pipe clamp is arranged outside the shell, the shell, the crack film and the hole film and the tightening pipe clamp are all made by a high-elasticity, high-resilience and high-tear-resistance material, and the surface of the valve is lubricated. By the high-elasticity channel valve, sealability is improved effectively, the requirement that operating instruments different in side share one valve can be met, and convenience in operation is realized. The high-elasticity channel valve can be used for improving a stabbing clamp, a single-hole multichannel puncture device and the like.
Description
Technical field:
The invention belongs to medical operating articles for use, be specifically related to high resiliency channel valve, for endoscope-assistant surgery apparatus and channel seal.
Technical background:
In recent years, rapidly, single-hole laparoscopic surgery is also universal gradually for Wicresoft's endoscope-assistant surgery development.Special surgical instrument stamp card (Trocars) and multi-passage puncture outfit (abbreviation perforator) are that operation is essential.Stamp card and perforator are all provided with channel valve, can make operating theater instruments enter people, taking-up, operation by channel valve, and overall process requires sealing.Existing stamp card and perforator valve are all and in duricrust, are provided with pore membrane and crack membrane structure.Be subject to housing rigidity to limit the corresponding size of each specification.If meet different size size dimension instrumentation requirement, need standby series stamp card; Perforator also will be established the multiple-way valve of correspondingly-sized, also will replace by standby stamp card.Can transition with little change greatly, little and can not to change greatly.In existing product, the safety of channel valve sealing is also lower.
Summary of the invention:
The object of the invention is to overcome the deficiency of prior art, a kind of new-type high resiliency channel valve of innovation, can meet many sizes apparatus and share, and better tightness, can be used for improving stamp card and perforator.
New-type channel valve of the present invention solves the technical scheme that its technical problem adopts:
This channel valve consists of housing, crack film, pore membrane and pipe collar, it is characterized in that: all of high resiliency, high resilience, high anti tear material, make, add the pipe collar that can apply constrictive force outside crack mould, pore membrane, housing.When surgical device enters people through valve, first wash crack open, then expand the mesopore of pore membrane, with mesopore, shrink lock ring apparatus and seal.The minimum dimension that is applicable to sealing should be a bit larger tham mesopore, and sealable full-size should be bordering on mesopore and tear the limit.For example, median pore diameter is 2 millimeters, and Materials Fracture percentage elongation is 600%, and its dimension limit should be less than 12 millimeters, selects 10 millimeters to be advisable.This channel valve can operate the apparatus of 3,5,10 millimeters.When material percentage elongation strengthens, dimension limit can strengthen thereupon.The crack of crack film can be a shape, ten shapes or Y shape, and while entering people's apparatus, crack is expanded, and after removal equipment, closing seam should be able to be replied in crack.Its applicable full-size should can be replied closing seam and is advisable not torn.In the time of meeting full-size, little size is all applicable.When crack is overextended by over dimensioning, material can produce residual deformation, and after removal equipment, crack may incomplete closing seam.For obtaining positiver sealing, at channel valve housing, add elastic tube hoop outward, with pipe collar contractility, tighten housing and crack, can strengthen closing of fracture, enhanced leaktightness.Thereby can expand apparatus suitable dimensions scope.0 also obviously increases sealing effectively and reliability.
Channel valve high resiliency used, high resilience, high tear resistance material, can select medical heat cure rubber (as High tear resistance silicon rubber), the thermoplastic elastomer (TPE) (as SEBS, SES etc.) of high elongation at tear.In housing, establishing crack film, pore membrane structural entity can be with molding or injection mo(u)lding, and pipe collar is with binding agent and the bonding location of housing.High resiliency channel valve also can be designed to outside pore membrane puts, and crack film is interior.
Channel valve surface is lubricated or chemistry painting lubricant processing through physical method vacuum coating, has self-lubricating property and can reduce to operate resistance.
Channel valve is stamp card (Trocars), multi-passage puncture outfit core component, if substitute with high resiliency channel valve, monocoque channel valve improves stamp card or multi-passage puncture outfit can significantly improve its sealing reliability and using adaptability.Stamp after improvement is arranged with channel valve and puncture tube; Single-hole multi-channel after improvement punctures, and it is provided with the outer snap ring of channel valve, multichannel, common-use tunnel, locating ring, vent line and incision protective sleeve, pipeline, interior snap ring.Interior snap ring strain embedding otch inwall sealing instrument that this single-hole multi-passage puncture outfit retracts cover with incision protection can pass through multiple-way valve seal operation.，
The following beneficial effect of tool of the present invention:
The applicable many specifications different size of 1 high resiliency channel valve apparatus.
2 high resiliency channel valve housings are provided with tightening tube hoop outward and strengthen closing of fracture sealing, can expand applicable apparatus size range and improve sealing reliability.
3 high resiliency channel valves can be used for improving stamp card, multi-passage puncture outfit.
Accompanying drawing explanation:
Fig. 1 channel valve structure cross-sectional schematic.
Fig. 2 channel valve is for improvement of stamp card schematic diagram
Fig. 3 channel valve is for improvement of multi-passage puncture outfit schematic diagram.
The specific embodiment:
Embodiment 1
High resiliency channel valve 1, by housing 1-1, is inside established crack mould 1-2, pore membrane 1-3 as shown in Figure 1, and peripheral hardware pipe collar 1-4 forms passage 1-5 and forms in housing.This design all adopts high resiliency, high resilience, high anti-tear material, establishes crack film, pore membrane in housing, whole with molding or injection molded, binding agent positioning housing periphery for pipe collar, and the inside and outside surface of channel valve is through vacuum coating lubricated.
Embodiment 2
Improve stamp and block high resiliency channel valve 1 and puncture tube 2 combinations as shown in Figure 2, puncture body forms improved stamp card with breather 2-1..After improving, stamp card can adapt to many sizes apparatus seal operation.
Embodiment 3
Improve multi-passage puncture outfit high resiliency channel valve 1 and the bonding location of multi-passage puncture outfit multichannel 2 as shown in Figure 3; perforator is also provided with flexible common-use tunnel 3, locating ring 4, its vent line 5, the outer snap ring of incision protection retractor, fexible film pipeline, interior snap ring.After improving, multi-passage puncture outfit can be avoided the mutual interference of apparatus phase, can adapt to different size apparatus positiver sealing by same channel valve.
