Description

Accurate-administration prostate syringe

Technical Field

The present application relates to the field of prostate injection technology, and more particularly, to a precise administration prostate syringe.

Background

The prostate injection therapy is to directly inject the medicine into the prostate, overcomes the blood prostate barrier, is less influenced by the pH value of the prostate liquid, increases the medicine concentration in the prostate and surrounding tissues by tens of times, has longer local residence time and avoids metabolism and inactivation, thus having maximum activity, and the injection is usually injected into the prostate through rectum.

The prior art publication CN202191549U provides a new type of prostate injector, which comprises a bottom cover, a face cover, a handle, a drive rod, a rack slider, a syringe and a needle. The transmission rod is sleeved in the handle in a gap manner, one end of the transmission rod is sleeved with the knob, the other end of the transmission rod is provided with the driving wheel, one end of the needle head is connected with the syringe, the other end of the needle head is fixedly connected with the rack sliding block, the middle part of the needle head is arranged in the handle in a penetrating manner, the rack sliding block is movably arranged in the guide groove of the face cover in a penetrating manner, and the longitudinal transmission teeth of the rack sliding block are meshed with the longitudinal transmission teeth on the driving wheel of the transmission rod. Because the injection needle is fixedly connected with the rack slide block, the longitudinal transmission teeth arranged on the inner side wall of the rack slide block are meshed with the longitudinal transmission teeth on the driving wheel of the transmission rod, and the injection needle can transversely extend out of the bottom cover to perform injection under the driving of the knob and the transmission rod.

The above prior art solution, though realizing the beneficial effects related to the prior art by the structure of the prior art, still has the following drawbacks:

the angle of the needle and the handle is fixed, the handle is inserted into the rectum along the anus, and the anus of a patient is contracted to clamp the handle, so that the angle and the position of the needle are difficult to adjust after the handle is inserted, the needle is not beneficial to adjusting the direction of the needle to the prostate, and the anus and the rectum of the patient are easily damaged due to strong adjustment.

In the related art, the inventor considers that the angle between the needle and the handle is fixed, and the handle is inserted into the rectum along the anus, and the anus of the patient contracts to clamp the handle, so that the angle and the position of the needle are difficult to adjust after the handle is inserted, the needle is not beneficial to adjusting the needle to the prostate, the anus and the rectum of the patient are easily damaged due to strong adjustment, and the accurate feeding of the medicine into the prostate is not beneficial.

In view of this, we propose a precisely dosed prostate syringe.
