技术领域technical field
本发明涉及医疗设备领域，具体的说是一种直视下膀胱局部化疗灌药装置。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.
背景技术Background technique
膀胱癌患者进行经尿道膀胱肿瘤电切除术后，大部分病人需要常规进行术后化疗药物的局部灌注治疗，根据不同的化疗方案，需要进行8次以上的化疗，患者在行膀胱局部灌注化疗过程中，需定期行膀胱镜检查，判断化疗疗效，及时发现可能存在的复发病变。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.
目前临床上无专用的直视下膀胱局部化疗灌药装置，使用常规导尿管，患者行尿道插管后从输入化疗药，有相当插管失败率，易造成尿道损伤，患者需要在膀胱化疗灌注过程中，需另外选择时间到医院行膀胱镜检查，判断膀胱灌注化疗效果及发现可能存在的复发病变，目前临床上无专用的直视下膀胱局部化疗灌药装置，使用常规导尿管，仅具有输注化疗药物的作用，且有无法直视下插管、不能观察膀胱内部情况、易损伤膀胱壁等缺点，因化疗药物的刺激作用，大部分患者在数次化疗过后，出现尿道瘢痕形成，尿道狭窄，导致常规插管困难，甚至无法继续进行膀胱局部灌注化疗，在行化疗药物局部灌注化疗过程中，医护人员无法观察到膀胱内部情况，无法判断化疗疗效和及时发现可能存在的复发病变，既不能做检查前后对比，也无法留存影像资料作教学等通途，患者在行膀胱局部灌注局部化疗过程中，需要额外到医院行膀胱镜检查，膀胱镜普遍较常规尿管粗，且目前我国大部分医院均使用硬质膀胱镜，易加重尿道损伤。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.
因此设计一种可以直视下进行尿道插管，避免尿管盲插所造成的尿道损伤，增加尿道插管的成功率，镜头在进入膀胱后可继续观察到膀胱内部情况，在撤出软性可调镜头后，可自行根据材料记忆卷曲，避免直接刺激膀胱壁造成损伤的局部化疗灌药装置，正是发明人要解决的问题。Therefore, design a urethral catheter that can be performed under direct vision to avoid urethral damage caused by blind catheter insertion and increase the success rate of urethral catheterization. After the lens enters the bladder, it can continue to observe the internal conditions of the bladder. After the lens is adjustable, it can automatically curl according to the material memory and avoid direct stimulation of the bladder wall to cause damage to the local chemotherapy drug delivery device, which is exactly the problem that the inventor wants to solve.
