Abstract
The invention discloses a fragment aspirator of a hematoma remover. The fragment aspirator comprises a knife head, a rotating type inner tube and a relatively stationary outer tube, wherein the rotating type inner tube is fixedly connected with the knife head; and the relatively stationary outer tube is used for sleeving the inner tube. The fragment aspirator is characterized in that the knife head comprises a conical head located in the front and a blade head located in the back; a plurality of liquid outlets communicated with a tube cavity of the inner tube are arranged on the conical head; the blade head is inserted into the front end of the outer tube; an axial knife edge groove is arranged on the blade head; a knife edge is arranged on a wall of the knife edge groove; a plurality of cutting edges are arranged on the blade head; the cutting edges are distributed along the circumferential direction of the outer tube; and when the knife head rotates, a shearing action for shearing hematoma can be formed between the blade and the knife edge. The fragment aspirator of the hematoma remover has the characteristics of simplicity in structure, easiness for processing, high cutting efficiency, small occupation space and the like.
Description
Technical field
The present invention relates to a kind of hematoma clearance device, especially a kind of crushing aspirating device of hematoma clearance device use.
Background technology
In cerebral hemorrhage treatment, use the hematoma clearance device clinically usually at present.Above-mentioned hematoma clearance device comprises crushing aspirating device and the balance lavage apparatus that links to each other with crushing aspirating device.Broken suction nozzle through on the crushing aspirating device cuts into tiny fragment with hematoma, through liquid flow tiny hematoma fragment is excreted then.The broken suction nozzle of existing crushing aspirating device adopts Archimedian screw structure cutter head, though can realize above-mentioned cutting function, exist product processing difficulties, stock-removing efficiency low, take shortcomings such as tube chamber is big.
This shows the crushing aspirating device of the prior art improvement further that awaits.
Summary of the invention
Task of the present invention is to solve the technological deficiency of the crushing aspirating device existence of hematoma clearance device in the prior art, and a kind of crushing aspirating device of hematoma clearance device is provided.
Its technical solution is:
A kind of crushing aspirating device of hematoma clearance device, comprise cutter head, be fixedly connected with cutter head rotary in pipe and be used to be nested with in guarantee and hold immobilized relatively outer tube; Above-mentioned cutter head comprises the blade head that is positioned at forward nose cone and is positioned at the rear portion; Nose cone is provided with some liquid outlets that are communicated with the tube chamber of interior pipe; Above-mentioned blade head inserts the front end of outer tube, and the blade head is provided with axial edge of a knife groove, and the cell wall of edge of a knife groove is provided with blade; Front end at outer tube is provided with the cutting edge that at least one cooperates with blade, when cutter head rotates, can form the shear action that hematoma is shredded between blade and the cutting edge.
Pipe was along the driving device of its axial rotation in the other end of pipe was connected with and can makes in above-mentioned.
The tube chamber of pipe forms back sap cavity as admission chamber in above-mentioned between outer tube and interior pipe, above-mentioned cutting edge, or sap cavity is connected back in the gap between cutting edge and blade head and the outer tube.
The cutting edge line of above-mentioned blade is a curved line.
Above-mentioned liquid outlet equiblibrium mass distribution on nose cone.
Above-mentioned blade has several, arranges along the circumferential equilibrium of blade head.
The present invention has following useful technique effect:
Characteristics such as the present invention has simple in structure, is easy to processing, and stock-removing efficiency is high, and it is little to take up room.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is illustrated further:
Fig. 1 is the structural principle sketch map of one embodiment of the present invention.
Fig. 2 shows a kind of decomposing state of Fig. 1 mode.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2, a kind of crushing aspirating device of hematoma clearance device comprises cutter head 1, interior pipe 2 and outer tube 3.On the end of pipe, manage along the driving device of its axial rotation in the other end of interior pipe is connected with and can makes in above-mentioned cutter head is fixedly connected on, manage in driving by driving device and rotate, carry the corresponding rotation of cutter head by interior pipe; Outer tube is nested with interior pipe, and promptly interior pipe is positioned at outer tube, and outer tube keeps relative transfixion; The tube chamber 4 of pipe forms back sap cavity 5 as admission chamber in above-mentioned between outer tube and interior pipe.Above-mentioned cutter head comprises the blade head 102 that is positioned at forward nose cone 101 and is positioned at the rear portion; Nose cone is provided with some liquid outlets 6 that are communicated with the tube chamber of interior pipe; More concrete mode can be that promptly above-mentioned liquid outlet equiblibrium mass distribution on nose cone is used so that flushing is more balanced; Above-mentioned blade head inserts the front end of outer tube, and the blade head is provided with axial edge of a knife groove 9, and the cell wall of edge of a knife groove is provided with blade 7, and above-mentioned blade can have several, and these blades can be arranged along the circumferential equilibrium of blade head; Front end at outer tube is provided with several cutting edges that cooperates with blade 8, and cutting edge can be arranged along the circumferential equilibrium of outer tube, and a cutting edge can certainly be arranged, and when cutter head rotates, can form the shear action that hematoma is shredded between blade and the cutting edge.Above-mentioned cutting edge, or sap cavity is connected back in the gap between cutting edge and blade head and the outer tube.
In the aforesaid way, the cutting edge line of blade is preferably curved line, in order to realize along sliding shearing.
Operation principle of the present invention is roughly following:
Drive interior pipe rotation by driving device, carry the corresponding rotation of cutter head by interior pipe; Blade on the cutter head and the cutting edge on the outer tube are sheared mutually, and hematoma is shredded, and the hematoma fragment can get into back sap cavity by cutting edge.Meanwhile, spray the liquid outlet of working solution from cutter head by the admission chamber entering, and be able to, or the gap between cutting edge and blade head and the outer tube is back to back sap cavity from above-mentioned cutting edge.Flowing liquid drives the hematoma fragment and excretes.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this description, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection scope of the present invention.
