Direct viewing bladder local chemotherapy medicine injection device

Abstract

The invention discloses a direct viewing bladder local chemotherapy medicine injection device. The direct viewing bladder local chemotherapy medicine injection device includes an operation device and a specially-made catheter; the operation device includes a light source, a signal cable, a flexible video shot, a host, a display screen, and a direction adjustment knob; the specially-made catheter includes a catheter outer opening and a memory material; the display screen is connected to the host and arranged above the host; the host is connected to the direction adjustment knob through the signal cable; the direction adjustment knob is connected to the flexible video shot through the signal cable; the host is connected to the light source; and the light source is connected to the direction adjustment knob. Direct viewing urethral catheterization can be achieved, urethral damage due to blind insertion of the catheter can be avoided, and the successful rate of urethral catheterization can be improved; the condition of an internal part of a bladder can be continuously observed after the catheter enters the bladder, and a chemotherapy medicine cure effect and possible relapse pathological changes can be determined; after the flexible adjustable shot is pulled out, the specially-made catheter can curl over automatically according to material memory, and damage to a bladder wall due to direct stimulation can be avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a drug filling device for local chemotherapy of the bladder under direct vision. Background technique [0002] After transurethral resection of bladder tumors in patients with bladder cancer, most patients need routine local infusion of chemotherapy drugs after surgery. According to different chemotherapy regimens, more than 8 times of chemotherapy are required. Periodic cystoscopy is required to judge the efficacy of chemotherapy and detect possible recurrent lesions in time. [0003] At present, there is no special direct-view bladder local chemotherapy injection device in clinical practice. A conventional urinary catheter is used. After the patient is intubated into the urethra, chemotherapy drugs are injected from the patient. There is a considerable failure rate of the intubation, which is likely to cause urethral damage. During the perfusion process, it is necessary to cho...

Problems solved by technology

[0003] At present, there is no special direct-view bladder local chemotherapy injection device in clinical practice. A conventional urinary catheter is used. After the patient is intubated into the urethra, chemotherapy drugs are injected from the patient. There is a considerable failure rate of the intubation, which is likely to cause urethral damage. During the perfusion process, it is necessary to choose another time to go to the hospital for cystoscopy to judge the effect of intravesical infusion chemotherapy and find possible recurrent lesions. At present, there is no dedicated device for local chemotherapy infusion of bladder under direct vision in clinical practice. Conventional catheters are used. It only has the effect of infusing chemotherapy drugs, and has the disadvantages of intubation under direct vision, observation of the internal conditions of the bladder, and easy damage to the bladder wall. Due to the stimulating effect of chemotherapy drugs, most patients develop urethral scars after several chemotherapy sessions Formation, urethral stricture, leading to difficulty in routine intubation, and even inability to continue local infusion chemotherapy of the bladder. During the local infusion chemotherapy of chemotherapy drugs, medical staff cannot observe the internal conditions of the bladder, and cannot judge the efficacy of chemotherapy and detect possible recurrence in time The lesion can neither be compared before and after the examination, nor can the image data be retained for teaching and other channels. Patients need to go to the hospital for cystoscopy during the local chemotherapy of local bladder infusion. Cystoscopy is generally thicker than conventional urinary catheters, and currently Most hospitals in China use rigid cystoscopes, which can easily aggravate urethral injury
