The technical solution of the utility model is:
A kind of multi-functional surgery of nasal cavity rotary-cut cutter, it is characterized in that it comprises inner sleeve 1 and trocar sheath 2, inner sleeve 1 is actively plugged in the trocar sheath 2, have cutter head 3 in the zigzag on one end of inner sleeve 1 insertion trocar sheath 2, the perforate that interior cutter head 3 forms communicates with the channel of chip removal 4 of inner sleeve 1, the other end of inner sleeve 1 is equipped with and drives chuck 5, drives chuck 5 and is provided with the zigzag motor interface 6 that links to each other with drive motors, and channel of chip removal 4 communicates with vacuum extractor; Shape has the outer cutter head 7 of the zigzag that matches with interior cutter head 3 on one end of described trocar sheath 2, the other end of trocar sheath 2 is connected with irrigation sleeve 8, irrigation sleeve 8 is provided with water filling port 9, thereby water filling port 9 communicates with the inner chamber of trocar sheath 2 flushing liquor is delivered to interior cutter head 3 places, the high temperature resistant inner seal ring 10 that the flushing liquor that prevents in the trocar sheath 2 leaks is installed in irrigation sleeve 8, high temperature resistant inner seal ring 10 is positioned in the irrigation sleeve 8 by opening trim ring 11, on inner sleeve 1, be set with exterior seal ring 12, the one side of exterior seal ring 12 offsets with driving chuck 5, and the interior step surface of another side and irrigation sleeve 8 offsets.
Described inner sleeve 1 is the rustless steel inner sleeve, and trocar sheath 2 is the stainless steel outer sleeve pipe, drives chuck 5 and drives chuck for rustless steel, and irrigation sleeve 8 is the rustless steel irrigation sleeve, and water filling port 9 is the rustless steel water filling port.
Described trocar sheath 1 is straight tube, bend pipe or folding tubular construction, and when described trocar sheath 1 was bend pipe or folding tubular construction, described inner sleeve 2 was made up of two straight lengths and the spiral type section of flexibly connecting.
The beneficial effects of the utility model:
This utility model is simple in structure, easily manufactured, can adopt difform rotary-cut cutter to excise lesions position fast according to lesions position, can not stay any cicatrix in face, help improving operation efficient, provide the operating theater instruments of reason phase for eradicating the nasal cavity stubborn disease.
This utility model all adopts the rustless steel manufacturing, and is reusable after high temperature is eliminated, and helps reducing patient's financial burden, reduces surgery cost.
Description of drawings
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is two of a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
Embodiment one
As shown in Figure 1.
A kind of multi-functional surgery of nasal cavity rotary-cut cutter, it comprises rustless steel inner sleeve 1 and stainless steel outer sleeve pipe 2, inner sleeve 1 is actively plugged in the trocar sheath 2, have cutter head 3 in the zigzag on one end of inner sleeve 1 insertion trocar sheath 2, the perforate that interior cutter head 3 forms communicates with the channel of chip removal 4 of inner sleeve 1, the other end of inner sleeve 1 is equipped with rustless steel and drives chuck 5, drives chuck 5 and is provided with the zigzag motor interface 6 that links to each other with drive motors, and channel of chip removal 4 communicates with vacuum extractor; Shape has the outer cutter head 7 of the zigzag that matches with interior cutter head 3 on one end of described trocar sheath 2, the other end of trocar sheath 2 is connected with rustless steel irrigation sleeve 8, irrigation sleeve 8 is provided with water filling port 9, thereby water filling port 9 communicates with the inner chamber of trocar sheath 2 flushing liquor is delivered to interior cutter head 3 places, the high temperature resistant inner seal ring 10 that the flushing liquor that prevents in the trocar sheath 2 leaks is installed in irrigation sleeve 8, high temperature resistant inner seal ring 10 is positioned in the irrigation sleeve 8 by opening trim ring 11, on inner sleeve 1, be set with exterior seal ring 12, the one side of exterior seal ring 12 offsets with driving chuck 5, the interior step surface of another side and irrigation sleeve 8 offsets, as shown in Figure 1.In addition, for the ease of the location of trocar sheath 2, prevent its rotation, also be connected with centring ring 13 on irrigation sleeve 8, it can realize engagement with the positioning sleeve on the casing of drive motors.
Can earlier the drive sub 5 of inner sleeve 1 of the present utility model be inserted on the output shaft of motor during use, sawtooth on the motor output shaft is meshed with sawtooth in the drive sub 5, will drive drive sub 5 when motor rotates like this rotates, driving connects 5 and drives inner sleeve 1 rotation again, and the suction catheter with the negative pressure straw device communicates with the inner chamber of inner sleeve 1 simultaneously; Then trocar sheath 2 is sleeved on the inner sleeve 1, simultaneously normal saline (flushing liquor) outlet tube is linked to each other with water filling port 9, when motor rotates, the inner cutter high speed rotating excises lesions position, excise parts simultaneously and further pulverize under the effect of outer cut, siphon away from inner sleeve together with flushing liquor, the tissue that the flushing liquor that water filling port injects not only will excise sweeps away, simultaneously cutter head is played cooling effect, prevent the high temperature tissue of burning.
Embodiment two.
As shown in Figure 2.
The difference of present embodiment and embodiment one is, trocar sheath is not a straight tube, also be bend pipe or folding pipe, at this moment, in order to guarantee that inner sleeve can drive interior cutter head high speed rotating, inner sleeve 2 can be designed to be made up of two straight lengths and the spiral type section of flexibly connecting, the spiral type section of flexibly connecting 14 not only is convenient to stretch into the bending section of trocar sheath, and can transmit cutter head high speed rotating in the moment of torsion drive.
This utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
