Abstract
The utility model relates to a magnetic puncture housing with helixes of an abdominal cavity, applied with a puncture needle, wherein, a sheath body (8) is arranged at the middle of the housing, the side of the sheath body is communicated with a fluid valve (9), and a sheath tube (10) is arranged at the lower part, which is characterized in that: the outside wall of the sheath tube is provided with helixes (10-1); a helical tooth section is saw-shaped. The utility model has the advantages of simple and reasonable structure, being easily controlled when inserting the body cavity, and being hard to slide out after inserting, improving the safety in operation, higher seal performance, favorable for opening and closing the seal-capping and protecting the mirror surface.
Description
Technical field
This utility model relates to a kind of abdominal paracentesis apparatus, specifically is a kind of abdominal cavity magnetic recording tape spiral puncture cover, and it and puncture needle are used.
Background technology
Straight tube puncture cover in the prior art because the sheath pipe is very smooth, has the possibility that skids off behind the insertion body cavity, stays accident potential easily.
Summary of the invention
This utility model technical issues that need to address are, overcome the deficiency of prior art, provide a kind of simple and reasonable, insert body cavity time ratio and are easier to control, are difficult for the abdominal cavity magnetic recording tape spiral puncture cover that skids off after the insertion.
Magnetic recording tape spiral puncture cover in abdominal cavity of the present utility model has the sheath body in the middle of it, and the sheath pipe is arranged at the bottom, and sheath body one side is communicated with the liquid valve, it is characterized in that described sheath pipe outer wall is provided with spiral, helical tooth cross section toothing.Because sheath pipe outer wall is provided with spiral, the frictional force between puncture cover and the human body increases, and makes the probability that skids off reduce greatly.
This utility model can also adopt and rely on the technology of magnetic attraction sealing puncturing hole to improve usability.Be connected with joint on the sheath body described in the utility model, both have O-ring seals on the connecting portion, and Capsule is arranged at joint top, have on the Capsule and the close-fitting hole of puncture needle external diameter; The bottom is with the magnetic lid, is provided with Magnet in the lid and respectively becomes semi-round ring shape with aluminium block.The bottom is fluted, and magnetic has the irony capping in the groove, and all there is pit on the two sides of irony capping, and groove and irony capping have smooth flat, with the through hole sealing of joint.By above measure, the seal request of the cover that can guarantee to puncture helps the breakthrough that capping is opened, and can also play a protective role to minute surface.
This utility model is simple and reasonable, inserts body cavity time ratio and is easier to control, is difficult for after the insertion skidding off, and has improved processing safety; Also improved sealing, helped that capping is opened and the protective effect of minute surface.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing this utility model is done and to be described in further detail.
Embodiment 1.This routine abdominal cavity magnetic recording tape spiral puncture cover has sheath body 8 in the middle of it, and sheath body one side is communicated with liquid valve 9, and sheath pipe 10 is arranged at the bottom, and sheath pipe outer wall is provided with spiral 10-1, helical tooth cross section toothing.After the body cavity puncture, will overlap and be screwed into puncturing hole by the hand of spiral, reach the precalculated position after, can carry out next step operation.
In the middle of this routine abdominal cavity magnetic puncture cover sheath body 8 is arranged, be connected with joint 2 on the sheath body, both have O-ring seals 7 on the connecting portion.Sheath body one side is communicated with liquid valve 9, and sheath pipe 10 is arranged at the bottom.Capsule 1 is arranged at joint top, has on the Capsule and the close-fitting hole 1-1 of puncture needle external diameter; The bottom is with magnetic lid 3, and permanent magnet 4 respectively becomes semi-round ring shape with aluminium block 6 in the lid.The fluted 2-1 in joint bottom, magnetic has irony capping 5 in the groove, and all there is pit 5-1 on the two sides of capping, and groove and irony capping have smooth flat, with the through hole 2-2 sealing of joint.
After the puncture cover is retained in body cavity, do not having apparatus fashionable from the passage interpolation, capping 5 is attracted to be close to joint 2 by the magnetic force of permanent magnet 4, has realized channel lumen and extraneous sealing.When having apparatus to insert in the passage, apparatus promotes capping 5, and capping 5 is opened by shown position, and operating apparatus can be passed through smoothly.When apparatus was extracted, capping 5 was got back to original position again under magneticaction, seal.
Claims (2)
