Abstract
Description
Technical Field
[0001] The invention belongs to the field of extracorporeal lithotripsy, and in particular relates to a painless lithotripsy device for urethral stones. Background Art
[0002] When medical staff examine and treat patients' urethral stones, they need to use urethral stone treatment instruments. At present, medical staff generally use ordinary urethral stone treatment instruments, which are mainly operated by medical staff. When medical staff examine and treat patients' urethral stones, they use extracorporeal shock wave lithotripsy to break up stones. Extracorporeal shock wave lithotripsy is to generate shock waves through the urethral stone treatment instrument, which are focused by the machine and aimed at the stones. After multiple releases of energy, the stones in the body are broken up and discharged from the body with urine. The existing common urethral stone treatment device cannot adjust its position according to the actual needs of the patient during use. It has simple functions, cumbersome operation, and is prone to errors. It cannot meet the various necessary requirements of medical staff well, causing many inconveniences in the treatment of urethral stones, thereby bringing great difficulty to the work of medical staff.
[0003] In view of this, the present invention is proposed. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a painless lithotripsy device for urethral stones, thereby solving the problems raised in the above-mentioned background technology.
[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: A painless lithotripsy device for urethral stones comprises: a bed, a bottom pad is arranged on the upper side of the bed, and a movable protective cover is slidably matched on the upper side of the bed; An airbag is arranged inside the movable protective cover, an air inflation and deflation assembly connected to the airbag is arranged on the upper side of the movable protective cover, a recess is arranged below the airbag, a stone crushing assembly fixedly connected to the recess is arranged inside the airbag, and a tension spring is arranged between the stone crushing assembly and the movable protective cover; A placement groove is provided at the bottom of the bed, a touch display controller electrically connected to the stone crushing assembly is arranged in the placement groove, a rotating rod is rotatably connected between the touch display controller and the placement groove, a ratchet check assembly matching the rotating rod is arranged in the bed, and a pressing plate corresponding to the ratchet check assembly is provided on one side of the bed.
[0006] Optionally, the inflation and deflation assembly includes an air pipe disposed on the movable protective cover and connected to the airbag, and a valve core disposed in the air pipe.
[0007] Optionally, the stone crushing assembly includes an arc box, a battery arranged in the arc box, a shock wave generator and a shock wave setter, and a plurality of shock wave emission heads arranged below the arc box and electrically connected to the shock wave generator; the battery, the shock wave generator and the shock wave setter are electrically connected to each other, and the tension spring is located between the arc box and the movable protective cover.
[0008] When it is necessary to crush the patient's affected part, first move the movable protective cover to the patient's affected part, then inflate the airbag through the inflation and deflation assembly, the airbag expands and fits the patient's affected part through the recessed portion, and the recessed portion drives the arc box to contact the patient's affected part. At this time, start the shock wave generator, and the shock wave emitted by the shock wave generator is irradiated to the human body through multiple shock wave emission heads. The shock wave penetrates the human body and focuses on the urinary stones in the body, releasing energy to crush the stones, and the stone fragments are naturally discharged.
[0009] Optionally, two slide grooves are provided on the upper side of the bed body, and a slider which slides with the two slide grooves respectively is installed on the lower side of the movable protective cover, and a limiting assembly is arranged between the slide groove and the slider; the limiting assembly includes a plurality of limiting grooves provided on one side of the slide groove, a groove provided on one side of the slider, a limiting block located in the groove and corresponding to the limiting groove, and a spring installed between the limiting block and the groove; the limiting groove is a hemispherical structure, and the limiting block is a spherical structure.
[0010] Optionally, a chamber connected to the placement groove is provided on the lower side of the bed, and the ratchet check assembly is located in the chamber; the ratchet check assembly includes a ratchet that is interference fit on the circumferential side of the rotating rod located in the chamber, and a check pawl that rotates and elastically fits in the chamber and engages with the ratchet; a movable shaft is rotatably fitted in the chamber, the check pawl is fixedly connected to the end of the movable shaft, a torsion spring is fixedly connected between the check pawl and the chamber, the torsion spring is located on the circumferential side of the movable shaft, and one side of the pressing plate is fixedly connected to the circumferential side of the movable shaft.
[0011] When the pressing plate is pressed, the pressing plate moves downward and drives the non-return pawl to move. The non-return pawl releases the lock on the ratchet by rotating the movable shaft. The non-return pawl releases the lock on the ratchet and also releases the fixation of the rotating rod. When the touch display controller is rotated out of the placement slot, the non-return pawl locks the ratchet through the elastic force of the torsion spring. The non-return pawl locks the ratchet and fixes the rotating rod at the same time. The rotating rod can fix the touch display controller and can be fixed when the touch display controller is rotated out of or into the placement slot, thereby facilitating the use or folding of the touch display controller.
[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below at the same time: By setting a movable protective cover on the bed body, the position of the movable protective cover can be moved according to the affected part of the patient, which can drive the stone crushing assembly to move, so that the position of the stone crushing assembly can be adjusted according to the actual needs of the patient; Through the airbag arranged inside the movable protective cover, when the patient's affected part needs to be lithotripped, the airbag is inflated through the inflation and deflation assembly, so that the airbag can be expanded and fit the patient's affected part through the recessed part, and the recessed part drives the lithotripsy to fit the patient's affected part. The lithotripsy can be started to lithotripsy the patient's affected part. On the one hand, the expansion of the airbag and the fit with the abdomen are convenient for keeping the patient's affected part warm, reducing the situation of the patient catching a cold during the lithotripsy process. On the other hand, it is convenient to lithotripsy the patient's affected part, thereby increasing the application range of the device. The ratchet non-return assembly arranged at the bottom of the bed body can fix the touch display controller when it is rotated out of or into the placement slot, thereby facilitating the use or folding of the touch display controller.
