Background technology
At present, the kidney puncture needle that general hospital uses structurally only contains needle handle and shank, shank is used for thrusting kidney, needle handle is used for allowing doctor's hands hold, the defect of this common kidney puncture needle is the length of shank is fixing, because everyone skin surface is different from the distance of kidney, therefore, the length of these common kidney puncture needlies is longer with regard to what arrange, so that the kidney of different patient can be thrust, but kidney puncture needle will be caused like this when puncture, in the process being punctured to kidney, bending phenomenon is there will be because length is long, after there is bending phenomenon in kidney puncture needle, predetermined puncture position will be departed from, cause puncture failure, and need again to puncture after puncture failure, damage the health of patient, and the treatment time of patient can be incured loss through delay, practical application effect is poor.
Utility model content
This utility model will solve above-mentioned prior art Problems existing, a kind of kidney puncture needle is provided, rational in infrastructure, easy to use, the adjustable length of kidney puncture needle can be realized, the different length of kidney puncture needle can be used according to the demand of different patient, ensure that kidney puncture needle there will not be buckling phenomenon in the process of puncture, can ensure to puncture successfully, be beneficial to patient treatment, meet the demand of people.
This utility model solves the technical scheme that its technical problem adopts: this kidney puncture needle, comprise a syringe for allowing doctor hold, the front end of syringe is connected with one for thrusting kidney from human skin and length-adjustable shank, shank comprises front shank and rear shank, the rear end of front shank is connected with the front end of rear shank, the rear end of rear shank is connected with syringe, the rear end of front shank is connected with the pull bar for driving the movement in rear shank of front shank, shank before pull bar one end connects, the other end of pull bar is connected with the plectrum extended to outside rear shank, rear shank have for allowing the groove one of plectrum movement on rear shank, groove one being connected with one group allows plectrum be embedded into groove two on rear shank, arrange in vertical state between groove two and groove one, groove two is arranged on rear shank in ordered state, the front end of front shank is connected with the syringe needle for thrusting human body.After arranging like this, rational in infrastructure, easy to use, during use, according to the penetration length of needs of patients, plectrum is mobile in groove one, then the pull bar on plectrum drives front shank to move in rear shank, now, the length of shank just starts to occur change, elongated or shorten, when the length of shank reaches the length of needs, stop mobile plectrum, then plectrum is embedded in the groove two of relevant position, now, the length of shank no longer changes, reach the effect of metering needle pole length, such kidney puncture needle would not cause buckling phenomenon because length is long when thrusting patient body, therefore kidney puncture needle can puncture according to predetermined puncture position, there will not be off-set phenomenon, also can not bend, reach the successful object of puncture, can not the health of injured patient, the treatment time of patient can not be incured loss through delay, practical application effect is good.
The junction of front shank and rear shank is provided with for thrusting the arc-like sheet preventing scratch human body in human body process at shank, and arc-like sheet is connected on rear shank.After arranging like this, the setting of arc-like sheet is that result of use is good in order to shank scratch human body after preventing shank from preventing in the process of thrusting human body.
The piston core bar for driving seal wire to enter kidney in shank is provided with in syringe.After arranging like this, piston core bar enters kidney for driving seal wire in shank, facilitate seal wire to enter kidney by piston core bar and carry out sampling or other treatment, and piston core bar can move in syringe, is convenient to doctor's operation, easy to use.
The effect that this utility model is useful is: kidney puncture needle of the present utility model, rational in infrastructure, easy to use, the length of kidney puncture needle can be regulated, realize the adjustable length of kidney puncture needle, the different length of kidney puncture needle can be used according to the demand of different patient, ensure that kidney puncture needle there will not be buckling phenomenon in the process of puncture, can ensure to puncture successfully, can puncture according to predetermined puncture position, there will not be off-set phenomenon, also can not bend, can not the health of injured patient, the treatment time of patient can not be incured loss through delay, practical application effect is good, be beneficial to popularization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: syringe 1, shank 2, front shank 3, rear shank 4, pull bar 5, plectrum 6, groove 1, groove 28, syringe needle 9, arc-like sheet 10, piston core bar 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: this kidney puncture needle in the present embodiment, comprise a syringe 1 for allowing doctor hold, the front end of syringe 1 is connected with one for thrusting kidney from human skin and length-adjustable shank 2, shank 2 comprises front shank 3 and rear shank 4, the rear end of front shank 3 is connected with the front end of rear shank 4, the rear end of rear shank 4 is connected with syringe 1, the rear end of front shank 3 is connected with the pull bar 5 for driving the movement in rear shank 4 of front shank 3, shank 3 before pull bar 5 one end connects, the other end of pull bar 5 is connected with the plectrum 6 extended to outside rear shank 4, rear shank 4 have for allowing the groove 1 of plectrum 6 movement on rear shank 4, groove 1 is connected with one group and is embedded into groove 28 on rear shank 4 for allowing plectrum 6, arrange in vertical state between groove 28 and groove 1, groove 28 is arranged on rear shank 4 in ordered state, the front end of front shank 3 is connected with the syringe needle 9 for thrusting human body.
