Description
Technical field
The present utility model belongs to medical apparatus and instruments, relates to the zoom shock wave source for extra chock wave lithotriptor, its be a kind of to treatment wave source utilize physical principle change its treatment focal length machinery.
Background technology
Extra chock wave lithotriptor is very universal, is the prefered method for the treatment of now urinary system calculus.The shock wave source for the treatment of calculus is the critical component of lithotrite, and the focal spot size of shock wave source concentration of energy, focusing, focal length length are major parameters, and national sector standard has requirement to this.For example, YY0001-2008 " external initiation rock crushing plant technical requirement " regulation, the focal length of lithotrite can not be less than 110mm.
The focal length of lithotrite refers to: pressure pulse generation source port plane focuses on the distance of maximum any to pressure.Conventionally, the focal length of lithotrite design is fixed, and in the time for the treatment of, focal length is divided into two parts, and the one, the distance from patient's epidermis to calculi in vivo, another section is exactly the degree of depth of the WATER AS FLOW MEDIUM (being isolated by water pocket) that produces shock wave.And at human body, because treatment position difference, people's fat or thin difference, this focal length variations is just very large, for example people of 70 kg body weight, the vesical calculus degree of depth (ventricumbent position) approximately only has 30mm, and ureter stage casing calculus may be exactly 100mm; The about 80mm of people's ureter stage casing calculus degree of depth of 50 kg body weight and 100 kg body weight and 150mm (not considering height differences), the focal length of existing lithotrite is fixed, and need to change by water pocket harmomegathus the different treatment degree of depth.
Conventionally a fixing long focus of lithotrite design, most of producers are in 130mm left and right, and part is 150mm, is individually 110mm, utilizes water pocket harmomegathus to change focal length.Be suitable for crowd by long-focus in theory wider, but long-focus can run into water pocket harmomegathus while being used in compared with short distance and keep the difficulty of shape; The uncared-for problem of another one is that long-focus is while being used in short distance, the larger problem of meeting produce power density, at distance focal point 60mm place, the incident area of 150mm focal length wave source is 1.5 times of 110mm, like this, long-focus wave source is used for treating short distance calculus and just easily causes skin injury than short focal length wave source, so being lithotrite, desirable situation can select easily suitable focal length according to different patients, namely can change focal length, alleviate the epidermis injury that may cause, especially treating child more needs to consider as far as possible.
But focus is the pinpoint datum mark of lithotrite calculus on lithotrite, its position can not arbitrarily change.If change focal length on the machine of x-ray or B ultrasonic location, mean that focus also can change, this is unacceptable.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes lithotrite zoom shock wave source, by changing condenser lens and lens riding position, in the situation that keeping focus constant, realize multiple spot zoom, thereby solve the deficiency of prior art.
In order to solve the problems of the technologies described above, the technical scheme that this utility model adopts is, lithotrite zoom shock wave source, comprises shell, electromagnetic disc, B ultrasonic positioner, lens subassembly and water pocket, and B ultrasonic positioner is fixedly connected with shell; Described electromagnetic disc is located at outer casing bottom, and described lens subassembly is bolted on shell, and water pocket is dismountable to be located on lens subassembly.
As a kind of feasible scheme, described lens subassembly is 150mm condenser lens, realizes 150mm and focuses on.
As the feasible scheme of another kind, described lens subassembly comprises 130mm condenser lens and 130mm zoom support, and 130mm zoom support is bolted on shell, and 130mm condenser lens is located on 130mm zoom support, focuses on thereby realize 130mm.
As the feasible scheme of another kind, described lens subassembly comprises 130mm zoom support, 110mm condenser lens and 110mm zoom support, 130mm zoom support is bolted on shell, 110mm zoom props up and is set up on 130mm zoom support, and be bolted on shell, 110mm condenser lens is located on 110mm zoom support, focuses on thereby realize 110mm.
Further, between described shell and water pocket, be also provided with sealing ring, play the effect of sealing.
Further, B ultrasonic positioner comprises Ultrasonic-B probe, positioner, locating support and loose collar (or claiming rotating disk), described loose collar is sheathed on shell, locating support is fixedly connected with loose collar, positioner is located on locating support, Ultrasonic-B probe is by protruding in positioner, and in the time that Ultrasonic-B probe is flexible from positioner, the center extended line of this Ultrasonic-B probe meets at the rubble focus at wave source center all the time.
This utility model passes through such scheme, shock wave source is made to dismountable several assembly, in the time that it changes focal length, as long as change corresponding support and lens, without the position that changes former focus, avoid the variation of focus, just do not need again focus point, focusing yet, not needing to change positioner, is a kind of simpler, feasible, the practical scheme that changes focal length.Lithotrite zoom shock wave source of the present utility model is applicable to utilize the refraction type electromagnetic impact wave apparatus of lens focus.
