Charged hook irrigating sleeveTechnical field
This utility model belongs to surgical operating instrument field, relates in particular to a kind of charged hook irrigating sleeve that is applicable to Minimally Invasive Surgery.
Background technology
Minimally Invasive Surgery because wound is little, the advantage such as few of losing blood used more and more widely.Operation need to be opened some passages at human body, and all kinds of operating theater instruments are from these passage turnover human bodies.Irrigating sleeve is exactly a kind of apparatus often using in operation, is specifically designed to toward passing into liquid in body and cleans or sterilize and operation be created in to bloodstain, the waste liquid in body or the little bits meat the like waste that cuts down takes out.The most of function of existing irrigating sleeve is all more single, namely only can pass into liquid and suction garbage.If irrigating sleeve and other operating theater instruments can be combined, not only can reduce the passage of opening on human body, reduce patient's the pain of injury, and simplify, facilitated doctor's operation technique, saved operating time.TURP and coagulation are the functions of relatively commonly using in Minimally Invasive Surgery, and the structure that realizes its function is not very complicated yet, are therefore necessary these functions to focus on irrigating sleeve.
Summary of the invention
The purpose of this utility model is, provides that a kind of current collection is cut, coagulation, passes into liquid and suction garbage function charged hook irrigating sleeve.
To achieve these goals, the technical solution adopted in the utility model is: a kind of charged hook irrigating sleeve, comprise main body, extension, feed tube and suction tube, in main body, there is feed pathway and suction channel, extension is connected with main body, and be communicated with feed pathway and suction channel, feed tube is connected and is communicated with feed pathway with main body, suction tube is connected and is communicated with suction channel with main body, main body is provided with liquid feed valve and suction valve, liquid feed valve is in feed pathway, be used for controlling feed pathway, suction valve is in suction channel, be used for control and suck passage, it is characterized in that, also comprise the electric hook being arranged in extension, the outer end that electricity hook stretches out extension.
This utility model has been set up electric hook in extension, electricity hook provides radio-frequency current by connected external high frequency generator, electricity hook can be realized TURP and coagulation function, traditional passing on liquid and suction garbage function basis, increase TURP and coagulation function, can reduce the passage of opening on human body, reduced patient's the pain of injury, and simplify, facilitated doctor's operation technique, saved operating time.
Further, described electric hook is fixedly mounted in main body, and extension can axially movably be arranged in main body, and main body is provided with and can makes orthokinetic push button with extension, and push button is connected with extension, and push button is for controlling the flexible of extension.Extension adopts flexible design; the length that electricity hook stretches out extension can need to regulate according to operation; in order to avoid encounter patient's non-operative site by mistake; reduce patient trauma, while not making, electricity hook can be retracted in extension, and electric hook is played a protective role; and electric hook is fixedly mounted in main body; guaranteed that electric hook connects reliable, in operation process, can not produce movement, improved operation precision.
Further, in described extension, be provided with stainless steel tube, stainless steel tube is fixedly mounted in main body, and electric hook is welded on steel pipe.This scheme has facilitated the installation of electric hook, makes electric hook more firm with being connected of main body.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the charged hook irrigating sleeve of this utility model.
Below in conjunction with accompanying drawing, this utility model is described in detail.
The specific embodiment
Referring to Fig. 1, charged hook irrigating sleeve comprises main body 1, extension 2, feed tube 3 and suction tube 4, in main body 1, there is feed pathway and suction channel, extension 2 is connected with one end of main body 1, and be communicated with feed pathway and the suction channel of main body 1 inside, feed tube 3 is connected with the other end of main body 1 with suction tube 4, feed tube 3 is communicated with the feed pathway of main body 1 inside, suction tube 4 is communicated with the suction channel of main body 1 inside, main body 1 is provided with liquid feed valve 5 and suction valve 6, liquid feed valve 5 is in feed pathway, be used for controlling feed pathway, suction valve 6 is in suction channel, be used for control and suck passage.Extension 2 is rigid pipe, and material can be the insulant such as plastics.Feed tube 3 and suction tube 4 are flexible pipe, and material is plastics or rubber etc.Feed tube 3 is connected with the external instrument (such as syringe, saline bottle etc.) of certain pressure liquid can be provided, when needs pass into liquid and clean, open liquid feed valve 5, liquid will enter from feed tube 3 feed pathway of main body 1 inside, then flows out from extension 2.Suction tube 4 for example, is connected with the external instrument (vacuum extractor) of certain negative pressure can be provided, and in the time the garbage in body need to being aspirated, opens suction valve 6, and garbage is just drawn out of through extension 2, suction channel and suction tube 4 successively.
Electricity hook 7 is arranged in extension 2, and head stretches out the outer end of extension 2, and head is L-shaped, can also be other shapes that are applicable to operation technique.In extension 2, be provided with stainless steel tube, stainless steel tube is fixedly mounted in main body 1, and electric hook 7 is welded on steel pipe, and electric hook 7 is fixedly mounted in main body 1 by stainless steel tube.Because electric hook 7 is thinner, be poorly directly fixedly mounted in main body 1, by stainless steel tube, the installation of electric hook is just very simple and convenient, and electric hook is more firm with being connected of main body.Extension 2 can axially movably be arranged in main body 1, and main body 1 is provided with and can makes orthokinetic push button 11 with extension 2, and push button 11 is connected with extension 2, and push button 11 is for controlling the flexible of extension 2.Extension 2 adopts flexible design; the length that electricity hook 7 stretches out extension can need to regulate according to operation; in order to avoid encounter patient's non-operative site by mistake; reduce patient trauma, while not making, electricity hook can be retracted in extension, and electric hook is played a protective role; and electric hook is fixedly mounted in main body; guaranteed that electric hook connects reliable, in operation process, can not produce movement, improved operation precision.Electricity hook 7 is connected with electric wire 10, and electric wire 10 is connected with outside high frequency generator again, and high frequency generator provides radio-frequency current for electric hook 7, and controls electric hook 7.The button of circuit board and the electric hook 7 of control also can be set in main body 1.
Main body 1 is provided with grasping part, and grasping part comprises bent plate part 8 and cylindrical section 9, bent plate part 8 be middle part to the thin plate of main body inside bend, cylindrical section 9 is cylindrical shape in the inner side of bent plate part and substantially.The design of grasping part meets ergonomic structure, and doctor in use takes up comfortable labor-saving more.Between extension 2 and grasping part, become 90 degree angles, use more smoothly, laborsaving and comfortable.Extension 2, feed tube 3, suction tube 4, liquid feed valve 5 and suction valve 6, all in the same side of grasping part, make structure compacter, orderly, and in using, manual free space is larger.
