Operation principle
The puncture casing of One-time-use Perforator supports the use with One-time-use Perforator, One-time-use Perforator
Pneumoperitoneum should be initially set up as peritoneoscope instrument, then cut a little otch at abdominal part correct position, will puncture
Device is fixed on pneumoperitoneum with hands at an appropriate angle and raises on your abdominal part, and together with puncture awl, the puncture casing of perforator is inserted little cutting
In mouthful, with hands pin the puncture taper shank block of perforator encase upper cover position down by, when perforator meets obstructions bigger
Time firing button automatically open up stab knife and just go out sheath, along with puncture awl, stab knife puncture soft tissue lower floor with puncture casing
The oblique section of lower bands tapering enters soft tissue together, and at stab knife cone through patients abdomen soft tissue until abdominal cavity, this punctures
Sleeve pipe inserts abdominal cavity until in the middle part of puncture casing along with puncture awl.
When meeting obstructions smaller when, stab knife is with regard to automatic retracted, thus can ensure that and will not accidentally injure any of abdominal cavity
Internal organs.Guarantee that abdominal operation is normally carried out by disposable puncture device gas injection valve, safe and reliable.
One-time-use Perforator is owing to arranging hemispherical sealing ring, sealing plain washer, one-way seal valve and play one-way sealing
Envelope effect, when on the puncture conehead of puncture awl assembly, puncture awl setting of casing, puncture awl, sleeve pipe is transferred to, when wearing from puncture casing
Thorn cone assembly transfers to from puncture casing, open the valve switch on gas injection valve top, gas pass through gas injection valve air inlet, spool,
Valve body injects patient abdominal cavity from puncture casing, makes patient abdominal cavity heave, and closes valve switch, and abdominal operation apparatus can be from one
The positioning and guiding lid of secondary property perforator, hemispherical sealing ring, sealing plain washer, one-way seal valve enter puncture casing, and pass through
Puncture casing is inserted in abdominal cavity, due to be provided with hemispherical sealing ring, seal plain washer, one-way seal valve etc. multi-sealed,
Sealing abdominal operation apparatus performance good, injecting gas in abdominal cavity will not leak, operation terminate after by operating theater instruments from disposable wearing
Thorn device is transferred to, opens valve switch, excrete patient abdominal cavity injects gas from the air vent of gas injection valve, gas to be implanted
After body is discharged, disposable puncture device can be transferred to from patients abdomen.
The thorn sleeve design of One-time-use Perforator is reasonable, compact conformation, uses safely, effectively, in clinical operation
Can greatly reduce wound area, be greatly shortened operating time, reduce the hemorrhage and postoperative infection of patient, improve operation matter simultaneously
Amount.Owing to puncture awl assembly is provided with sleeve pipe on stab knife, puncture handle of a knife, puncture conehead, puncture awl setting of casing, puncture awl, wears
Thorn taper shank, percussion stop button and puncture taper shank block, can penetrate abdominal tissue easily and will not scratch its hetero-organization of intraperitoneal,
Owing to using hemispherical sealing ring, sealing the multiple-sealed device sealing property such as plain washer, one-way seal valve reliably, operation process
In the gas that is injected in abdominal cavity by disposable puncture device gas injection valve do not leak out in operation process, such that it is able to really
Guarantor's abdominal operation is normally carried out, safe and reliable.
Owing to the studded shape of puncture casing outer surface is protruding, increase frictional force, can effectively prevent puncture casing at stomach wall
Upper slip.The graininess of described puncture casing outer surface is protruding in flat, smooth surface, to tissue injury's I in case
Sliding, postoperative pain is light, and healing is fast.Owing to the graininess of puncture casing outer surface is protruding in flat, it is not required to during dial-out rotate, can
Directly transfer to, time-consuming, easy to operate.
