Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
A kind of sealing element for puncture outfit of the invention, as shown in Figs. 1-2, including the deformation being fabricated from a flexible material
Gas access way 1 is arranged on deformable body for body, and gas access way includes air inlet and exhaust outlet, by inflating to deformable body
Either exhaust makes it expand or shrink；Air inlet and exhaust outlet can be realized by valve and be opened and closed, so realize into
Gas and degassing function.It is of course possible to it is readily comprehensible, a stomata, the compatible air inlet of the stomata can be only set on deformable body
And degassing function, external two valves (air intake valve 11 and drain tap 12) of the stomata, as shown in fig. 7, gas access way 1
Air valve 11 and drain tap 12 are tapped into respectively, is controlled by valve, realize air inlet and degassing function.
Through-hole 3 is set on deformable body, and surgical instrument is entered intraperitoneal by the through-hole 3.The center of circle of through-hole 3 and puncture cannula
4 central axis is on the same line；Work as air inlet open, gas enters in deformable body, and deformable body expansion reduces through-hole, will
Surgical instrument package, realizes sealing function；If without placing surgical instrument, the expansion of deformable body inner inflatable, through-hole in through-hole 3
3 shrink until closing.When closing air inlet, exhaust outlet is opened, when the gas inside deformable body is discharged, deformable body is shunk, and is led to
Hole 3 is expanded, and surgical instrument is enable to facilitate taking-up；In addition, being evacuated by exhaust outlet to deformable body inner body gas, due to becoming
Body is fabricated from a flexible material, and the diameter of through-hole 3 is opened to maximum to the peripheral expansion of deformable body, will not influence hand by through-hole 3
The placement and taking-up of art instrument.The section of deformable body is symmetrically arranged vertebra shape structure.Be conducive to the contraction of through-hole 3.
In one embodiment, deformable body split settings are made up of at least two parts.Splice composition deformation by two parts
Body；It can be improved the leakproofness of through-hole 3 in this way.When by deformable body around through-hole 3 center around limitless defense right at several
Part, it is envisioned that when inflating to each section, each section is expanded to the center of circle, can achieve a better sealing effect.Such as figure
Shown in 10, the section of deformable body 31 is vertebra shape structure, because deformable body is made up of two parts, being equivalent at connecting sewing makes hand
The through-hole 311 that art instrument passes through therefore, there is no need to that through-hole 311 additionally is arranged, also be able to satisfy the effect of sealing.
In one embodiment, in a ring, and the center of deformable body is arranged in through-hole 3 to deformable body.In this way, deformable body and logical
Hole 3 is concentric circles, guarantees deformable body uniform force in inflation, avoids generation portion from excessively expanding, expand deformable body
Deformity influences the leakproofness of through-hole 3.
In one embodiment, flexible material can be in rubber, plastics, thermoplastic elastomer (TPE) and fabric with sealant
It is a kind of, wherein rubber is high resiliency high-molecular compound, has elasticity, and have good leakproofness, when inflated,
It can be fitted closely with surgical instrument.Certainly, flexible material can also be the fabric with sealant.
In one embodiment, as in Figure 3-5, deformable body is swollen to upper and lower both direction in inflation in order to prevent
It is swollen, the waste of gas is caused, and the deformation efficiency of deformable body is low, extruding force dispersion, the sealing effect of through-hole 3 substantially reduces.
Therefore, deformable body periphery is arranged for limiting and guiding deformable body to the guide housing 5 of 3 center swell of through-hole.Wherein, guide housing 5
Including guide plate 51 and support plate 52, guide plate 51 is mounted in support plate 52, and section is concave, deformable body setting
Between guide plate 51 and support plate 52, that is, it is arranged in the groove of concave, restrained deformation body is expanded with lower section upwards,
Deform it to the center swell of through-hole 3.In one embodiment, guide plate 51 and the contact surface setting of support plate 52 are several
A positioning column 511, and 511 matched location holes 521 are set with positioning in the setting of the corresponding position of support plate 52, in order to make to be oriented to
Plate 51 and support plate 52 can be securely attached to together, and location hole 521 and positioning column 511 are interference fitted；In addition, for convenience
Guide housing 5 is mounted in puncture outfit, by the prominent location hole 521 of positioning column 511, is fixed protrusion with puncture outfit, can be kept away
Exempt from that more installing components are arranged.
On the basis of in the above-described embodiments, fixed edge 6 is arranged in the periphery of deformable body, solid by fixed edge 6 and guide housing 5
It is fixed, it prevents deformable body to be displaced, influences the sealing effect of through-hole 3.Preferably, can be arranged and positioning column on positioning side 6
511 corresponding fixation holes 61.
In order to keep the sealing effect of sealing element more preferable, multiple deformable bodys can be superposed.Two changes are usually arranged in parallel
Body.
The invention also discloses a kind of puncture outfits, as seen in figs. 6 and 8, including the sealing element in above-described embodiment, further include
Inlet channel 7, gas are inflated to abdominal cavity by inlet channel 7, are allowed to form pneumoperitoneum；Sealing element is arranged in puncture outfit,
It is connected to or disconnects with inlet channel 7 by the air inlet that valve controls deformable body.Gas outlet passes through valve direct emission.Work as pass
The valve for closing gas outlet opens the valve of air inlet, is inflated by the gas in inlet channel 7 to deformable body, makes to deform
Body dilatancy.When the valve for opening gas outlet, the valve of air inlet is closed, intracorporal gas is deformed and is exhausted directly to operating room
Interior, through-hole 3 is expanded.Deformable body is controlled by the gas that pneumoperitoneum is filled, external gas source is not necessarily to, keeps structure simple, is reduced
Cost.
The invention also discloses another puncture outfits, and as shown in figs. 2 and 9, the sealing element including above-described embodiment further includes
Inlet channel 7 and discharge flue 8, gas are inflated by inlet channel 7 to abdominal cavity, are allowed to form pneumoperitoneum, then pass through row
Cigarette leads to the smog generated during 8 pairs of operations and vapor discharge abdominal cavity.Sealing element is arranged in puncture outfit, passes through valve control
The air inlet of deformable body processed is connected to or disconnects with inlet channel 7, and exhaust outlet and the smoke evacuation of deformable body are controlled by valve
The connection of channel 8 disconnects.When the valve for closing gas outlet, the valve of air inlet is opened, by the gas pair in inlet channel 7
Deformable body is inflated, and makes deformable body dilatancy.When the valve for opening gas outlet, the valve of air inlet, deformable body row are closed
Gas, through-hole 3 are expanded.By the negative pressure of discharge flue, can cracking discharge deform intracorporal gas, through-hole 3 is to deformable body
Peripheral expansion opens the diameter of through-hole 3 to maximum, will not influence the placement and taking-up of surgical instrument.By 7 He of inlet channel
Discharge flue 8 cooperates valve to control deformable body, is not necessarily to external equipment, can be achieved with the control to deformable body, make structure
Simply, cost is reduced.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
