Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to the sealing device of the perforator used in laparoscopic surgery and employ the perforator of sealing device.
Background technology
Laparoscopic surgery obtains to be applied more and more widely, in order to avoid nosocomial infection, the consumption of the disposable puncture device (Trocar) used in laparoscopic surgery is also increasing, on the basis ensureing serviceability, simplify structure, reduce costs, improve performance, this trend has become the direction that perforator improves.
The hermetically-sealed construction of the perforator of prior art is made up of radial direction seal ring and check valve.Wherein common check valve, i.e. axial sealer, have two kinds.One is spring pressuring plate formula structure, promotes baffle plate compressing silica gel sealing ring form sealing by spring leaf.Be made up of spring leaf, baffle plate, silica gel sealing ring, spring leaf, baffle plate adopt rustless steel manufacture usually, and often use in the perforator that the sealing ring of this form manufactures at nonexpondable metal, this perforator price is more expensive, heavier-weight.In recent years, in order to adapt to the needs of disposable puncture device development, develop infundibulate silica gel sealing ring, this infundibulate silica gel sealing ring has a through otch of straight line in funnel shaped bottom, utilize the pressure that in the contractility of silica gel itself and use procedure, CO2 pneumoperitonium is formed, reach the effect of sealing, this infundibulate silica gel sealing ring widely uses usually in disposable puncture device.Radial direction seal ring adopts the funnel-shaped structure of band centre bore usually, and this sealing ring especially easily leaks when operating theater instruments is rocked, and dynamic sealing effect is poor.In addition, when in the medical silica-gel sealing ring at 4mm, when inserting the operating theater instruments of 10mm or 12mm, the reciprocating resistance of operating theater instruments is also large, and this brings inconvenience to surgical operation.
In addition, the head of operating theater instruments has various different shape, is particularly similar to the operating theater instruments that titanium clamp pincers is this kind of, when sending to intraperitoneal through perforator, its binding clip is the V-shaped of opening, and the infundibulate silica gel sealing ring of prior art often cannot pass through this kind of operating forceps.The another one shortcoming of V word infundibulate silica gel sealing ring is operating theater instruments that is fluted to heads such as ultrasound knifes or raised step, easily blocks operating theater instruments when exiting, and moves not smooth.
Thus the apex combustion seal improving existing perforator is needed, to reach the apparatus that not only can use 10mm on the perforator of diameter for 10mm, and the operating theater instruments of any diameter between 5mm ~ 10mm can be used, the same apparatus that not only can use 12mm on the perforator that diameter is 12mm, and the operating theater instruments of any diameter between 5mm ~ 12mm can be used, reach general object.Meanwhile, the apex combustion seal of the perforator after this improvement can adapt to various difform operating theater instruments, facilitate entering and exiting of apparatus, and resistance is low, fluent motion.Obviously, the sealing device of prior art and perforator, still can not meet this requirement, thus needs to improve.
Summary of the invention
The object of the present invention is to provide the sealing device that a kind of perforator uses and the perforator employing this sealing device, the operating theater instruments of any diameter between 5mm ~ 12mm can have been used, realize its versatility; Not only require good sealing effect, and lower resistance when operating theater instruments moves back and forth will be realized thereon.
