Power, the pump housing 11 transmit the liquid of predetermined pressure to water knife assembly 2 by pressure piping 12.Also, one end of pressure piping 12 leads to
Cross high pressure connection 13 and connect liquid outlet, pressure piping 12 connects the pump housing 11 quickly, stable connection, transmits the liquid of predetermined pressure not
Easily leakage.Pump assembly 1 is connected detachably with water knife assembly 2, after the completion of operation, dismounting pump assembly 1 and water knife assembly 2, and pump
Body component 1 can sterilize reuse, reduce operation cost.
Refer to Fig. 6 in the lump again, it is the schematic diagram of the water knife assembly 2 of the embodiment of the present invention one.As illustrated, water knife assembly
2 include return duct 21, adapter 22, water knife outer tube 23, feed tube 24 and scraper 25.Return duct 21 is located in handle 6, return duct
The other end of 21 one end connection pressure piping 12, adapter 22 are arranged at return duct 21, and adapter 22 is located in handle 6, turns
Joint 22 connects the other end of pressure piping 12, and water knife outer tube 23 runs through first passage 311 and the connecting adapter of laryngoscope component 4
22, water knife outer tube 23 is run through in one end of feed tube 24, and one end of feed tube 24 connects the another of pressure piping 12 by filter 26
One end, the connection insertion outer tube 31 of scraper 25, scraper 25 connect the other end of feed tube 24, the corresponding water knife outer tube 23 of scraper 25.Again
Fig. 7 is referred in the lump, and it is the schematic diagram of the scraper 25 of the embodiment of the present invention one.As illustrated, scraper 25 has a fluid passage
251, fluid passage 251 connects feed tube 23, and the outlet of fluid passage 251 corresponds to water knife outer tube 23.External workstation is passed through liquid
Liquid pressing to predetermined pressure, the pump housing 11 are transmitted the liquid of predetermined pressure by pressure piping 12 by body to the pump housing 11, the pump housing 11
To feed tube 23, feed tube 23 transmits the liquid of predetermined pressure to scraper 25, and it is thin to patient's polyp of vocal cord that doctor operates scraper 25
Born of the same parents' tissue is cut, and after the liquid cutting that scraper 25 sprays, liquid turns into waste liquid, and waste liquid is sent to back by water knife outer tube 23
Flow tube 21, the transmission waste liquid of return duct 21 to devil liquor recovery station, without single liquid output pipe, reduces the financial burden of patient,
Reduce the risk of successive patients' infection.Also, water knife assembly 2 uses water knife, and the incising cell Tissue velocity of water knife assembly 2 is fast, right
Each position polyp of vocal cord more comprehensively, more thoroughly remove, and surgery, operating time substantially shortens, and water knife assembly 2 is cut off
Polyp of vocal cord will not cause secondary fire damage without thermal response to unexpected cutting tissue around, and water knife assembly 2 is disposable,
Prevent secondary cross-infection after corrective surgery.
Refer to Fig. 8 in the lump again, it inserts the schematic diagram of outer tube 31 for the connection of scraper 25 of the embodiment of the present invention one.As schemed
Show, in the embodiment of the present invention one, the connected mode of the connection insertion outer tube 31 of scraper 25 is laser welding.Using laser welding,
The connection insertion outer tube 31 of scraper 25 is firm, reduces production time and the production cost of polyp of vocal cord resectoscope, is cut in polyp of vocal cord
