Description
Technical field
The utility model is related to medical suction apparatus, particularly a kind of detachable orthopaedics attractor attachment structure.
Background technology
During bone surgery, medical worker will generally use attractor to attract the hematocele that operation is produced, and carry out
Often there are bone scraps and other tissues for easily blocking pipeline to produce during bone surgery, such as bone cement chip, spur and bone tumour group
Knit.The attractor that most of hospital uses is made up of vacuum suction pump and suction tube, is sucked hematocele by principle of negative pressure,
However, because bone surgery can usually produce some broken bone bits, therefore, during hematocele is attracted, it is easy to which broken bone is considered to be worth doing
Suction, so that suction tube be blocked, medical worker needs to dredge suction tube with elongated thing, could consider broken bone to be worth doing and take out,
This adds difficulty to the work of medical worker.
In order to anti-clogging typically can connection attractor and negative pressure source bellows pipeline on connection filter will be above-mentioned
The composition for easily blocking pipeline is filtered out, but filter is generally connected to the position close to attractor, and capacity is smaller, carry out compared with
Repeatedly cleaning filtrate is needed during complicated operation, operation progress is influenceed, using effect is undesirable.
Patent name is " bone surgery attractor ", the U of Authorization Notice No. CN 203169805, application number
201320224481.5, a kind of orthopaedics attractor, including suction pump and suction tube are disclosed, is provided with and expands in suction tube stage casing
Pipe, the front end for expanding pipe is provided with filtering cloth jar, expands pipe root provided with screen pack.The technical scheme does not disclose the fixation of screen pack
How mode, prevent leakage problem during use upon connection, while the device volume is larger, is unfavorable for actual use.
Lack effectively fixed screen pack in the prior art, be conveniently replaceable, prevent from using process gas leakage, small volume is convenient real
The orthopaedics attractor that border is used.
Utility model content
The purpose of this utility model is to provide a kind of effective fixed screen pack, is conveniently replaceable, and prevents from using process gas leakage, body
Product is small, the detachable orthopaedics attractor attachment structure of convenient actual use.
Detachable orthopaedics attractor attachment structure, including：
First connecting tube and the second connecting tube, first connecting tube are connected by screw thread with the second connecting tube, and described
One connecting tube presses close at connectivity port to be provided with external diameter at boss, the boss and is more than external diameter at connectivity port, second connection
Groove is set at pipe connectivity port, the groove internal diameter is more than away from the internal diameter at connectivity port；
Packing ring, the packing ring is placed between boss and the second connecting tube connectivity port；
Screen pack, the screen pack is placed in bottom portion of groove, one end away from connectivity port；
When the screen pack is pressed on bottom portion of groove by the connectivity port of the first connecting tube, packing ring is pressed in boss and
Two connecting tube connectivity ports.
The packing ring is flexible circular hollow thin slice.
The screen pack is circular shape sheet.
The internal diameter of first connecting tube is 2mm~5mm, and the internal diameter of the second connecting tube is 2mm~5mm.
Length after first connecting tube and the second connecting tube connection is 15cm~25cm.
First connecting tube or the second connecting tube are provided with the through hole of decompression.
The connecting tube of the utility model first is connected by screw thread with the second connecting tube, and the first connecting tube is pressed close at connectivity port
Provided with boss, at boss, external diameter, which is more than at external diameter at connectivity port, the second connecting tube connectivity port, is set to groove, groove internal diameter
More than away from the internal diameter at connectivity port, packing ring is placed between boss and the second connecting tube connectivity port, and screen pack is placed in groove
Bottom, one end away from connectivity port, compact conformation, small volume；Screen pack is pressed on recessed by the connectivity port of the first connecting tube
During trench bottom, packing ring is pressed in boss and the second connecting tube connectivity port, and now screen pack and packing ring are compacted, screen pack mistake
Filter extravasated blood and bone bits.When there is stopping state, screen pack is unclamped in the threaded connection of the first connecting tube of rotation and the second connecting tube
And packing ring, changed.The utility model effectively fixes screen pack, is conveniently replaceable, and prevents from using process gas leakage, small volume, side
Just it is Shi Jishiyong.
