Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the perforator that particularly relates to the sealing ring of the perforator used and used the sealing circle in laparoscopic surgery.
Background technology
Laparoscopic surgery has obtained application more and more widely, for fear of nosocomial infection, the consumption of the disposable puncture device used in laparoscopic surgery (Trocar) is also increasing, on the basis that guarantees serviceability, simplified structure, reduce costs, improve performance, this trend has become the improved direction of perforator.
The hermetically-sealed construction of the perforator of prior art is comprised of radial direction seal ring and check valve.
Common check valve, axial sealer, have two kinds.One is spring pressuring plate formula structure, promotes baffle plate compressing silica gel sealing ring by spring leaf and forms sealing.Spring leaf, baffle plate, silica gel sealing ring, consist of, spring leaf, baffle plate adopt the rustless steel manufacture usually, in the perforator that the sealing ring of this form is manufactured at nonexpondable metal, often use, and this perforator price is more expensive, and weight is heavier.It two is in recent years in order to adapt to the needs of disposable puncture device development, developed the 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, the carbon dioxide pneumoperitoneum forms, reach the effect of sealing, the infundibulate silica gel sealing ring of a this word otch is extensively used as check valve usually in disposable puncture device.
Radial direction seal ring of the prior art normally adopts the sealing ring of the funnel structure of the V-shape with centre bore of medical silica-gel manufacture, and there is following problem in the sealing ring of this prior art:
If have sealing effectiveness preferably during 1 insertion 5mm operating theater instruments,, when inserting the 12mm operating theater instruments, resistance during apparatus work is excessive, affects doctor's operation.
If, during 2 insertion 12mm operating theater instruments, the resistance of motion of apparatus is low, require the centre bore of V-shape funnel structure to increase, when inserting the 5mm operating theater instruments, sealing effectiveness is poor, and carbon dioxide leaks serious.
3, when inserting titanium clamp pincers, especially easily the sealing ring of V-shape funnel structure is punctured, form and damage, cause gas leakage, can not use.
For this reason, many improvement are arranged.One, be to adopt the conversion sheath, has the conversion sheath of the sealing ring of different-diameter by changing centre bore, reaches the purpose of using different apparatuses, increased like this operation in doctor's operation, and this technology is eliminated at present.
Another is that elastic network(s) is compounded in medical silica-gel, and the anti-apparatus that strengthens silica gel inserts ability, although this structure good sealing effect, while inserting the 12mm apparatus, resistance is very large, uses inconvenient.Particularly, when inserting titanium clamp pincers, the binding clip opened of titanium clamp pincers is easy to pierce through layer of silica gel, is stuck on elastic network(s), and apparatus can not insert.
The third is the structure that adopts similar photography shutter formula, by several diaphragms, superposes successively, forms the V-shape funnel structure, can facilitate like this insertion and the motion of the apparatus of different-diameter, has particularly avoided the damage entered of titanium clamp pincers; But, owing between each diaphragm, space being arranged, can not form sealing.Can only rely on the increasing of pneumoperitoneum apparatus to supplement carbon dioxide to intraperitoneal, make the supplementary carbon dioxide gas scale of construction be greater than the carbon dioxide gas scale of construction of leakage, maintain pneumoperitoneum and press, this hermetically-sealed construction gas leakage is more serious.
Obviously, the apex combustion seal that needs the perforator of improvement prior art, take on the perforator that to reach at diameter be 12mm and not only can use the apparatus of 12mm, and can use the operating theater instruments of any diameter between 5mm～12mm, not only can use the apparatus of 10mm on the same perforator that is 10mm at diameter, and can use the operating theater instruments of any diameter between 5mm～10mm, reach general purpose.Simultaneously, 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, and motion is smooth, and sealing property will be got well simultaneously; Particularly titanium clamp pincers can pass through, and can not cause damage to sealing ring.
Summary of the invention
The purpose of this utility model has been to provide a kind of all-purpose sealed circle of perforator use and the perforator that has used this sealing ring, can use the apparatus of any diameter between 5mm～12mm, realizes its versatility; Not only require good sealing effect, and the lower resistance will realize that operating theater instruments moves back and forth thereon the time.
