Description
Technical field:
This utility model provides a kind of attraction mucosa cartilage knife, belongs to medical instruments field.
Background technology:
The doctor will use operating equipment one mucosa cartilage knife and suction catheter (being connected suction pump thereafter) in doing surgery of nasal cavity.The mucosa cartilage knife is used for cutting and peels off the bronchia mucosal cartilage, and suction catheter then is used for effusive blood on the sucking-off wound surface.Existing mucosa cartilage knife and suction catheter are different independent operating theater instruments, need doctor and assistant to operate respectively when performing an operation, it generally is doctor's one hand-held nasal sinuses mirror, one hand-held mucosa cartilage knife operation, the assistant holds suction catheter, the doctor is cutting or is separating when needing the blood of sucking-off wound surface in the mucosa cartilage operation, the doctor withdraws from the mucosa cartilage knife from nasal cavity, stretching into suction catheter by the assistant attracts, during no assistant, the doctor wants oneself to change by suction catheter to attract, its major defect is no matter to be two people operation or one man operation, can only have an apparatus one mucosa cartilage knife or suction catheter to operate at nasal cavity at every turn, several seconds of change of equipment in the gap wound surface have blood to flow out again, very easily cause the art open country unintelligible, directly influence operative speed and operation quality.
Summary of the invention:
The purpose of this utility model is intended to overcome the weak point of above-mentioned prior art, and provide a kind of with the mucosa cartilage knife, peel off son and suction catheter close three be one, attraction mucosa cartilage knife simple in structure, easy to use.
This utility model is achieved through the following technical solutions: a kind of attraction mucosa cartilage knife, the flat tube shape handle of a knife that comprises cutter hub, links into an integrated entity with cutter hub with blade and release surface, the cutter hub outer rim is circular arc, its second circular arc is a blade, first circular arc is a release surface, cutter hub has the inner chamber that is communicated with the handle of a knife tube chamber, the release surface of cutter hub, blade are provided with the attraction mouth that is communicated with its inner chamber with the joint portion of handle of a knife, the front end of handle and cutter hub release surface are the passivity structure, have the vent of control suction pressure on the handle, the tail end of handle is equipped with the interface that connects suction catheter.
This utility model blade is fit to cutting bronchia mucosal, cartilage, handle of a knife front end and cutter hub release surface are the passivity structure, be fit to separate the bronchia mucosal cartilage, attract mouthful suitable sucking-off cutting with separate bronchia mucosal cartilage process in the blood that produces, the flat tube shape handle of a knife especially flat-shaped structure of vent leading portion helps exposing the visual field, art district.In operating process, doctor one people just can be implemented in the sucking-off of the cutting, separation and the blood that carry out the bronchia mucosal cartilage under the situation of not changing apparatus, compared with prior art, has both improved operative speed, the quality of performing the operation can be guaranteed again, the patient suffering can be reduced simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing:
A kind of attraction mucosa cartilage knife is made up of cutter hub 1, handle of a knife 2, lever 3, vent 4, interface 5, attraction mouth 6, blade 7, release surface 8, and cutter hub 1 outer rim is circular arc, and its second circular arc is a blade 7, and first circular arc is a release surface 8, and cutter hub 1 has inner chamber; Lever 3 is housed on the handle of a knife 2, has the vent 4 of control suction pressure on the lever 3, its tail end is equipped with the interface 5 that connects suction catheter, and handle of a knife 2 is the tubular body structure, and especially a section to handle of a knife 2 front ends is flat tubulose body structure from lever 3.Cutter hub 1 is structure as a whole with handle of a knife 2, and cutter hub 1 inner chamber and handle of a knife 2 tube chambers are interconnected, and the release surface 8 of cutter hub 1, blade 7 are provided with the attraction mouth 6 that is communicated with its inner chamber with the joint portion of handle of a knife 2, and the front end of handle of a knife 2 and cutter hub release surface 8 are the passivity structure.
In the operation technique, suction catheter interface 5 communicates with suction pump by conduit, the doctor holds handle of a knife 2 operations, use the cutting operation that mucosa cartilage blade 7 carries out the mucosa cartilage, use release surface 8 and carry out the strip operation of mucosa cartilage, when the blood and slime that in the aforesaid operations process, needs to remove in the operative region, only need applying finger to pin vent 4, blood and slime will flow out from attraction interface 7 through cutter hub 1 inner chamber and handle of a knife 2 tube chambers from attracting mouthful 6 blood and slime that suck by attracting mouth 6 to suck.
