Abstract
A scalpel with double spray holes and water jet cutting and a device thereof. The medical water jet surgical instrument consists of a water jet knife with double jet holes, a pressure hose, an energy converter, a pressure reducing valve, an oxygen cylinder, etc. The jet cutting is carried out by directly pressing sterile water with high-pressure oxygen. The water flow cutter head consists of a conical spray head core, a spray head body, a nut and a ball head body. The outer conic surface of the nozzle core is provided with two symmetrical grooves and two spray holes are formed in the nozzle body, and the ball head body is arranged in the nut by a ball cushion and connected with the nozzle body to enable the cutter head to rotate around the direction of X, Y. The device has simple structure, flexible use and convenient disinfection, and can greatly reduce the operation difficulty.
Description
A kind of sterilized water that utilizes goes from micropore high speed ejection, soft tissue such as cutting liver, spleen or brain and do not damage the two spray orifice jet water stream cutting surgical knifes and the device of diameter 〉=0.2mm blood vessel, and it belongs to medical jet water stream cutter operating theater instruments.
At present both at home and abroad the jet water stream operation device that uses has two kinds, and a kind of is use the motor-driven oil pump, generation high pressure oil stream, and setting-out again makes water eject from the micropore high speed of current cutter and cuts.Another kind be with air pump to air tank filling compressed air, remove setting-out again with compressed air, water ingoing stream cutter is again realized.All there is the power source complex structure in above-mentioned two kinds of devices, volume is big, noise is big, because power source is one, be not easy to very much sterilization, and the current cutter of above-mentioned two kinds of devices are the single hole injection, and cutting speed is lower, make the operating time lengthening.
Provide a kind of simple in structure, two spray orifices, jet water stream cutting surgical knife and device that the cutter head jet angle is adjustable in order to overcome above-mentioned defective this utility model.
It is a kind of air pressure ability of swimming structure, is to adopt the high pressure oxygen in the oxygen cylinder to be used as power, directly remove to press sterilized water after reducing pressure, and sterilized water is pressed into the current cutter again and cuts and realize.It is mainly by the current cutter, compositions such as gas one liquid transducer (abbreviation transducer) and oxygen cylinder, air relief valve, pressure hose, and oxygen cylinder directly is connected by pressure hose, air relief valve with transducer, and separates and be provided with.Thereby save air pump and gas tank, make apparatus structure simple, volume is little, noiselessness.The current cutter changes single hole and sprays for diplopore sprays, and promptly under the identical situation of jet diameter, cutting speed can double, and the ball-type joint is housed on cutter head, cutter head is rotated, so jet angle is adjustable at random around X, Y direction.Because transducer separates setting with pneumatic source, therefore move flexibly, carry, sterilize conveniently.
Specific embodiment of the utility model will elaborate in conjunction with the following drawings.
The two spray orifices of Fig. 1, jet water stream cutting surgical knife and schematic diagram of device.
The structure chart of the two spray orifices of Fig. 2, jet water stream scalpel.
Fig. 3 gas one liquid transducer schematic diagram.
This utility model is by negative pressure straw 1, current cutter 2, pressure hose 3,7, transducer 6, compositions such as air relief valve 8 and gas cylinder 9, gas cylinder 9 is an oxygen cylinder, it directly is connected with transducer 6 by air relief valve 8 and pressure hose 7, provides 0.5～2MPa oxygen to transducer 6, and described transducer 6 its tops are provided with filler 21, vent valve 23 and air inlet 24, hanging ring 22 its underparts are provided with water outlet stop valve 25.Described current cutter 2 is by cutter head 10, shelves water cover 11, the knife bar 19 of band water flow switch valve 20 is formed, wherein cutter head 10 is made up of the tapered sprinkler core 12 in the garden of cavity, sprayer body 14, nut 16, bulb body 18, ball pad 17, sealing ring 15, sprinkler core 12 outer garden poppet surfaces have two the 180 ° of symmetric grooves 13 that communicate with its inner chamber, and it is contained in and forms two axis angles of cut in the sprayer body 14 and become 11 ° spray orifice.And bulb one end of bulb body 18 is contained in the nut 16 by ball pad 17 and sealing ring 15, and nut 16 is connected with screw thread on the sprayer body 14 and is one.So cutter head 10 can rotate around X, Y direction by bulb body 18; The other end of bulb body 18 links to each other with the knife bar 19 of band cavity, and knife bar 19 tail ends are connected with the water outlet stop valve 25 of transducer 6 by pressure hose 3.Current cutter 2 and transducer 6 are non-corrosive material and make, and above-mentioned pressure hose 3,7 and sealing ring, ball pad are nontoxic resin material and make.
In use in the transducer 6 sterilized water is housed, in order to survey the water consumption of seeing in the transducer 6 at any time, dress is hung spring balance 5 on transducer 6 hanging rings 22, and is hung in together on the drip stand 4.
Its work process: open oxygen cylinder 9, high pressure oxygen is through air relief valve 8, reduce to 0.5～2.0MPa, sterilized water in the transducer 6 is extruded, and by the consumption of spring balance 5 monitoring sterilized water, current are through water outlet stop valve 25, pressure hose 3 ingoing stream cuttves 2, open the water flow switch 20 on the knife bar 19 of current cutter 2, sterilized water is sprayed from current cutter 2 cut, the mixed liquor after negative pressure straw 1 suction is simultaneously sprayed can be finished the whole surgery work process.
What the jet flow flow of current cutter 2 depended on sprinkler core 12 offers groove 13 degree of depth, its degree of depth preferably is located at 0.04～0.1mm, the length of its groove 13 is preferably 10～15 with dark ratio, in use can as required bell glass 11 be enclosed within the cutter head oppositely to splash to prevent that the water jet flow from impacting.This device can be sent into disinfection in the autoclave with current cutter 2 with transducer 6.
