Description

Disposable flexible ureteroscope with suction function

This invention is a disposable flexible ureteroscope with suction function, particularly a ureteroscope that can be used in urological surgery.

During urological surgery, in order to accurately examine the affected part of the patient's body and use surgical instruments to perform visualized surgical treatment, an endoscope is now inserted into the patient's body through a channel, and the endoscope is used to capture and transmit images of the affected part, so that the doctor can perform more accurate diagnosis and treatment through the images transmitted by the endoscope.

Among them, taking the endoscope used in urological surgery as an example, the endoscope includes a body and a tube portion extending from one end of the body, and a working channel for instruments to pass through is formed inside the body, and the working channel is connected to the tube portion. When performing urological surgery, before operating the endoscope, the doctor must first insert the supply equipment of the physiological saline perfusion system and medical instruments such as laser fibers into the working channel and extend them into the tube portion.

However, the working channel of the endoscope currently on the market is not a straight structure, but has a bent section. Therefore, when inserting an instrument, the end of the instrument is likely to hit the inner wall surface of the bent section of the working channel, causing the instrument to be stuck or damaged, or even the working channel to be damaged. In addition, the bent section of the working channel is likely to press the supply instrument pipeline of the physiological saline perfusion system, thereby causing a water supply problem.

The main purpose of this invention is to provide a disposable soft ureteroscope with suction function, hoping to improve the problem that current endoscopes are difficult to penetrate related medical instruments and easily affect the infusion of physiological saline.

To achieve the above-mentioned purpose, the disposable soft ureteroscope with suction function of the present invention comprises: A body, which comprises a connecting part, an extension tube part and a gripping part, the rear end of the connecting part forms a connecting hole, the extension tube part is arranged at the front end of the connecting part, a working channel is formed inside the connecting part, the working channel is connected to the connecting hole and extends straight to the front end of the extension tube part, the gripping part is arranged at the bottom of the connecting part and extends toward the rear end of the connecting part; A control mechanism, which comprises a control wheel and a plurality of control cables, the control wheel is pivoted on the gripping part of the body, the plurality of control cables are connected to the control wheel and the front end of the extension tube part, the control wheel can pivot and control the bending direction of the front end of the extension tube part through the plurality of control cables; and A drainage mechanism includes a drainage channel, a drainage switch and a drainage pipe. The drainage channel is connected to the working channel and extends toward the rear end of the grip. The drainage switch is arranged at the rear end of the grip and connected to the drainage channel. The drainage pipe is connected to the drainage switch. The drainage switch can control whether the drainage pipe is connected to the drainage channel.

A filling hole is formed on one side of the assembly portion, and the filling hole is connected to the working channel; in addition, the gripping portion is in an arc shape.

The disposable flexible ureteroscope with suction function can be applied to urological surgery, wherein the working channel of the disposable flexible ureteroscope with suction function extends straightly from the set of connection holes to the extension tube portion, so that instruments such as laser fibers can pass through the working channel smoothly, and the irrigation water flow of physiological saline can be kept smooth, so that the treatment process is smooth and more efficient, the operation time is reduced, and multiple protection effects are achieved for patients.

In addition, the drainage tube of the drainage mechanism of the disposable soft ureteroscope with suction function can be connected to an external suction device, whereby the doctor can press and switch the drainage switch so that the suction device can pass through the drainage mechanism to suction water inside the kidney or stone fragments produced during the laser lithotripsy process, thereby reducing the patient's renal internal pressure and expelling stones from the kidney of the lithotripsy patient, thereby protecting the kidney.
