Abstract
The utility model relates to an aspirator head for orthopedics, which comprises an aspirator pipe and a connecting part. The suction pipe is arranged at the front end of the connecting part, and the front end of the connecting part is of a cylindrical structure with the diameter larger than that of the suction pipe; the suction tube is inserted into the connecting part, and the part of the suction tube in the connecting part is provided with a filtering device. The tractor head is provided with a corresponding filtering device to filter the sucked bone debris, osteophyte and other tissues so as to prevent the tractor from being blocked; meanwhile, the spiral lines are arranged in the aspirator head, so that the aspirator head generates a certain vortex in the imbibition process, and the effect of preventing congestion can be achieved by generating a certain scouring on the congestion object through the vortex effect.
Description
Technical Field
The utility model relates to an aspirator medical apparatus, in particular to an aspirator head used for orthopedics.
Background
The aspirator is used for aspirating and removing the contents of hemorrhage, exudate, pus and thoracic organs in the operation, so that the operation is clear, and the pollution chance is reduced. The suction apparatus is used with the suction head in the application process, the principle is very simple, namely the negative pressure state of the suction head is manufactured by a certain method, so that substances outside the suction head can be extruded to the suction head by the atmospheric pressure, and the suction effect is achieved.
The aspirator head of the current aspirator for orthopedics is generally disposable and is arranged at the end part of the aspirator connecting pipe; when in use, the suction device is arranged at the end part of the connecting pipe of the suction device, but the suction device head is often blocked by bone fragments, osteophytes and other tissues in the orthopedic surgery process, so that the suction device head needs to be replaced, certain time is consumed in the surgery, and inconvenience is brought to the surgery process.
Disclosure of Invention
The utility model relates to an aspirator head used in orthopedics department, which is provided with a corresponding filtering device to filter the sucked bone debris, osteophyte and other tissues to prevent the aspirator from being blocked; meanwhile, the spiral lines are arranged in the aspirator head, so that the aspirator head generates a certain vortex in the imbibition process, and the effect of preventing congestion can be achieved by generating a certain scouring on the congestion object through the vortex effect.
The utility model discloses realize above-mentioned purpose and adopt following technical scheme:
an aspirator head for orthopedics comprises an aspirator tube and a connecting part.
The suction pipe is arranged at the front end of the connecting part, and the front end of the connecting part is of a cylindrical structure with the diameter larger than that of the suction pipe; the suction tube is inserted into the connecting part, and the part of the suction tube in the connecting part is provided with a filtering device.
The aspirator tube is a conical structure with a narrow front part and a wide tail part.
The filtering device comprises filtering holes arranged around the tail part of the suction apparatus pipe, and the filtering holes are uniformly distributed on the suction apparatus pipe; the tail end port of the aspirator tube is of a closed structure.
The inside of the aspirator tube is provided with spiral grains which are raised spiral grains or sunken spiral grains.
The tail part of the aspirator pipe is provided with a one-way valve which is of a one-way forward structure.
The utility model adopts the above technical scheme following beneficial effect has:
the filter device arranged on the suction apparatus tube can realize effective filtration of the washing liquid, and prevent the suction apparatus tube from being blocked by the sucked bone debris and other substances; meanwhile, the spiral lines in the suction device tube generate certain eddy in the process of absorbing the liquid, and the eddy can flush impurities in the suction device tube, so that blockage is further prevented.
The suction apparatus tube is designed to be narrow in front and wide in back, so that excessive bone fragments are prevented from entering the suction apparatus tube, and the bone fragments and impurities sucked into the suction apparatus tube have large moving space, so that accumulation type blockage is prevented.
The tail end port of the aspirator pipe is provided with a one-way valve which is one-way towards the front part and can not affect the work of the aspirator pipe, and in addition, an operator can conveniently clean the inside of the aspirator pipe by adopting a poker from the rear part of the aspirator pipe.
Drawings
Fig. 1 is a schematic view of the present invention.
In the figure, 1, an aspirator tube; 2, a connecting part; 3, a filtering device; 101, a filtration pore; 102, spiral texture; 103, a one-way valve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
An aspirator head for orthopedics, as shown in fig. 1, comprises an aspirator tube 1 and a connecting part 2.
The aspirator tube 1 is arranged at the front end of the connecting part 2, and the front end of the connecting part 2 is a cylindrical structure with the diameter larger than that of the aspirator tube 1; the suction tube 1 is inserted into the connecting part 2, and the part of the suction tube 1 positioned in the connecting part 2 is provided with a filtering device 3.
The aspirator tube 1 is a conical structure with a narrow front part and a wide tail part.
The filtering device 3 comprises filtering holes 101 arranged around the tail part of the aspirator tube 1, and the filtering holes 101 are uniformly distributed on the aspirator tube 1; the end port of the aspirator tube 1 is of a closed structure.
The aspirator tube 1 is internally provided with a spiral line 102, and the spiral line 102 is a convex spiral line or a concave spiral line.
The tail part of the aspirator pipe 1 is provided with a one-way valve 103, and the one-way valve 103 is of a one-way forward type structure.
During use, the suction head is arranged at the end part of the suction apparatus connecting pipe of the negative pressure suction device, then suction operation is carried out, and the lotion enters the connecting part along the suction apparatus pipe under the action of negative pressure and then enters the negative pressure suction device through the connecting pipe for collection.
Because the end diameter of the aspirator tube is smaller than the diameter of the rear portion, some larger bone debris substances are not sucked into the interior of the suction head during the suction process, and the space at the rear portion of the aspirator tube is relatively large, so that a certain degree of freedom is provided for the substances in the lotion, and the risk of blockage is reduced.
The imbibition is filtered by the filtration pore at the back of the aspirator tube, meanwhile, the spiral line arranged on the inner wall of the aspirator tube can provide a certain vortex for imbibition, so that the imbibition can wash the inside of the aspirator tube; the one-way valve arranged at the tail part of the suction apparatus tube can only be opened forwards, the one-way valve is closed when the liquid suction operation is carried out, the liquid suction with sundries can not enter the connecting part, and when the suction apparatus head is taken down, the suction apparatus head can be inserted into the suction apparatus tube from the rear part of the connecting part by adopting a poker to carry out cleaning operation.
