Embodiment 1

[0036] like figure 1 As shown, the urethral dilator for urological surgery provided by the embodiment of the present invention is provided with a ventilation valve 1, a balloon 2, a straight tube 3, an expansion tube 4, a guide wire 5, a syringe 6, a catheter 7, and an expansion rubber plug 8 , the second pressure detector 9, the third pressure detector 10, the first pressure detector 11, the controller 12, and the connecting joint 13.

[0037] The left end of the straight tube 3 is connected to the air bag 2, the guide wire 5 and the catheter tube 7 pass through the middle part, and the right end is fixedly connected with the expansion tube 4; One end of 7 is connected with a syringe 6, and the other end is fixedly arranged on the head of the guide wire 5; the top of the guide wire 5 is fixedly connected with an expansion rubber plug 8, and the expansion rubber plug 8 is fixed on the top of the expansion tube 4 at the same time; the inside of the expansion tube A second pres...

Embodiment 2

[0046] like figure 2 As shown, the urethral dilating system for the urological surgery comprises:

[0047] The pressure detection module 14 is connected with the main control module 15 and includes a pressure detection unit for detecting the pressure inside the air bag 2 and outside the expansion tube 4, and transmits the real-time detection data to the main control module.

[0048] The data processing module 16 is connected with the main control module 15 and includes a built-in computing chip and ancillary devices, which are used to convert the front and rear pressures in the airbag 2, calculate the amount of gas entering the expansion tube 4, and calculate the expansion tube 4 according to the The volume expanded by the amount of gas, and calculate the amount of anti-infection agent that needs to be injected.

[0049] The alarm module 17 is connected with the main control module 15 and includes an indicator light and an accessory device for alarming when the pressure dete...

Embodiment 3

[0054] like image 3 As shown, the use method of the urethral dilating system for the urological surgery specifically includes:

[0055] S101: The main control module controls the external air source to inflate the airbag, the pressure detection module detects the pressure in the airbag in real time, and transmits the result to the central control module, and the central control module transmits the transmitted data to the display module in real time, and the display module will The data is shown on the display.

[0056] S102: When the air pressure of the airbag detected by the pressure detection module reaches the standard value, the alarm module controls the indicator light to emit a red light alarm, and the main control module controls the external air source to stop the inflation operation of the airbag.

[0057] S103: Manually squeeze the air bag so that the gas in the air bag enters the expansion tube, and the pressure detection module detects the external pressure of t...

Abstract

The invention belongs to the technical field of medical equipment and discloses a urethral dilator for urological surgery, a control system and a method. The left end of a straight tube is connected to an air bag, the middle part is passed through by a guide wire and a catheter, and the right end is fixedly connected with an expansion tube; the air bag The first pressure sensor is built-in, and the left end is fixedly connected with a ventilation valve; one end of the catheter is connected with a syringe, and the other end is fixedly arranged on the head of the guide wire; the top of the guide wire is fixedly connected with an expansion rubber plug, and the expansion rubber plug simultaneously It is fixed on the top of the expansion tube; the inside of the expansion tube is respectively provided with a second pressure sensor and a third pressure sensor at the highest point of inflation; the first pressure sensor, the second pressure sensor and the third pressure sensor are respectively connected to the controller through built-in wires. The invention is reasonable in structure, easy to operate, and has flexibility, can not only realize urethral expansion but also reduce urethral injury and patient pain, can apply medicine in time after urethral expansion, avoid causing urethral inflammation, and is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a urethral dilator for urological surgery, a control system and a method. Background technique [0002] At present, the closest existing technology is: urethral stricture is a common disease in urology, and the causes of the disease are usually divided into three categories: traumatic factors, inflammatory factors, and congenital factors. The lesions mainly manifest as scars of different depths and densities, accompanied by urothelial defects and contractures of the tube wall, which finally affect normal urination. The simplest and most commonly used method for treating urethral stricture is urethral dilatation. The structure design of the existing urethral dilation equipment is unreasonable. Usually, stainless steel tubes are used to gradually dilate from thin to thick. Because the stainless steel body is hard, it will bring more pain to the patient during ...
