Abstract
A kind of perforator radial direction seal ring of the present utility model, there is sealing ring body, described sealing ring body has an end face and a bottom surface, a side and a through hole is formed between described end face and bottom surface, described side inner walls has internal strain groove, and the bottom margin of described internal strain groove is not connected with through hole.Sealing ring of the present utility model is when performing the operation, when operating theater instruments is through sealing circle, the internal strain groove of side can play the effect of tightly coated operating theater instruments, and when operating theater instruments withdraws, can cause the inside skull patch in side owing to withdrawing, and utilize the projection of internal strain trench bottom, can give side counteracting force, it can oppositely draw this side, thus operating theater instruments can't occur skull patch phenomenon in side when extracting out, thus the effect of movable sealing can be improved, avoid malpractice.
Description
Technical field
This utility model relates to technical field of medical instruments, in the perforator especially used in peritoneoscope micro-wound surgical operation, uses a kind of radial direction seal ring in this perforator.
Background technology
Single use microtrauma puncture device is the important apparatus in endoscope-assistant surgery, and it is that a kind of breast is outer, abdomen external cavity mirror instrument, is applicable to the apparatus setting up thoracic cavity, abdominal operation service aisle in thoracic cavity, chamber, abdominal cavity spectroscopy and operation process.When laparoscopic surgery starts, epiderm skin is cut at the puncture position chosen with scalpel, then with thread a needle part and the puncture casing transdermal enter body cavity of perforator, in order to avoid missing penetration damage abdominal visceral browser in this piercing process, need companion puncture in endoscope embedded puncture needle, because puncture needle head is transparent plastic material, in piercing process, so just can be observed the situation of puncture at any time by sight glass.
In modern medicine, peritoneoscope micro-wound surgical operation obtains to be applied more and more widely, in order to avoid nosocomial infection, the consumption of the disposable puncture device used in laparoscopic surgery is also increasing, on the basis ensureing serviceability, simplify structure, reduce costs the direction becoming perforator and improve.
The hermetically-sealed construction of the perforator of prior art is made up of radial direction seal ring and check valve.Wherein check valve has two kinds, and 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 the needs that suitable disposable puncture device develops, develop funnel type silica gel sealing ring, this funnel type silica gel sealing ring has a through otch of straight line in the bottom of funnel type, utilize the pressure that in the contractility of silica gel itself and use procedure, CO2 pneumoperitonium is formed, reach the effect of sealing, this funnel type silica gel sealing ring widely uses usually in disposable puncture device.Radial direction seal ring adopts the cirque structure of band centre bore, and to adopt be thick by outer rim and to the progressively thinning structure of centre bore, the thick sealing ring progressively thinning to centre bore of this outer rim is especially easily revealed when operating theater instruments is rocked, movable sealing weak effect.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the deficiencies in the prior art, improves sealing ring movable sealing effect in use, provides a kind of perforator radial direction seal ring, and it has delicate structure, reliability is high and cost is low feature.
This utility model solves the technical scheme that its technical problem adopts: have sealing ring body, described sealing ring body has an end face and a bottom surface, a side and a through hole is formed between described end face and bottom surface, described side inner walls has internal strain groove, and the bottom margin of described internal strain groove is not connected with through hole.The side of sealing ring body is offered internal strain groove, after fluting, the wall thickness at this place obviously can be thinning, when operating theater instruments penetrates through hole, distortion groove will preferentially deform, thus surround operating theater instruments, reach the object of sealing, and when operating theater instruments is rocked, after offering distortion groove, side has just been divided into multiple part by reality, these divided parts will along with rocking together, thus still can surround operating theater instruments, remain sealing state, thus improve the movable sealing effect of sealing ring, on the other hand, when operating theater instruments withdraws, due to the bottom margin of internal strain groove with via design for not to be connected, i.e. disconnected state, on the one hand can the intensity of reinforced bottom, the skull patch phenomenon bottom sealing ring can be prevented on the other hand, because the bottom of internal strain groove is not directly communicated with through hole, so when operating theater instruments withdraws, power when place can resist operating theater instruments pull bottom this, give counteracting force, thus prevent bottom from occurring skull patch, and then stop the skull patch phenomenon of whole sealing ring, thus sealing effectiveness is provided.
Further, for realizing internal strain groove and through hole not connected state, the groove bottom of internal strain trench bottom is provided with projection, this projection serves the effect strengthening bottom thickness proof strength, block the connected state of internal strain trench bottom and through hole simultaneously, thus the anti-skull patch function bottom sealing ring can have been realized.
Further, described internal strain groove is around being distributed in described side.
A kind of perforator, it has above-mentioned perforator radial direction seal ring.
The beneficial effects of the utility model are, sealing ring of the present utility model is when performing the operation, when operating theater instruments is through sealing circle, the internal strain groove of side can play the effect of tightly coated operating theater instruments, and when operating theater instruments withdraws, the inside skull patch in side can be caused owing to withdrawing, and utilize the projection of internal strain trench bottom, side counteracting force can be given, it can oppositely draw this side, thus operating theater instruments can't occur skull patch phenomenon in side when extracting out, thus the effect of movable sealing can be improved, avoiding malpractice.
