Problems solved by technology

However, one expansion operation needs to use dilators of different specifications for multiple repeated expansions. The operation is cumbersome, time-consuming and laborious, which greatly increases the operation time and increases the work pressure of medical staff. Therefore, how to solve the above problems has become the focus of research by personnel in this field.

Embodiment 1

[0018] Please refer to Figure 1 to Figure 2 As shown, the present embodiment provides a continuous expansion type fascial dilator for percutaneous nephroscopic surgery, including an expansion tube 1 and a guide 4, and the expansion tube 1 is composed of several tube segments 3 whose diameters are increased accordingly. Sliding connection between adjacent pipe sections 3 forms a telescopic tube structure, and the length of the pipe section 3 gradually increases from the outside to the inside, so that after the puncture is completed, the inner pipe section 3 can be taken out of the puncture channel, and the pipe section described in each section The front end of the section 3 is provided with a tip 2, the tip 2 is a cone shape, and the tip 2 of each subsequent tube section 3 fits with the outer peripheral wall of the previous tube section 3, so that the gap between the tube section 3 and the tube section 3 Swipe each other.

Abstract

The invention relates to the technical field of medical instruments, and discloses a continuous expanding type fascia dilator for percutaneous nephroscope surgery, which comprises a dilation guider and a dilation tube, the dilation tube is composed of a plurality of tube sections with the tube diameters increased in sequence, the adjacent tube sections are connected in a sliding manner to form a telescopic tube structure, the front end of each tube section is provided with a tip, and a through channel convenient for the dilation guider to penetrate through is arranged along the central axis of each tube section. A plurality of tube sections are adopted to form the dilation tube of the telescopic structure, during expansion, a puncture channel is punctured section by section until a channel with a proper diameter is achieved, multiple groups of dilation tubes with different specifications do not need to be prepared for repeated expansion in the whole operation process, the operation is convenient, the operation time is greatly saved, and the working pressure of medical personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a fascia dilator for continuous expansion type percutaneous nephroscopic surgery. Background technique [0002] Percutaneous nephroscopic surgery is an important method for the treatment of modern urinary stones, which can crush and remove stones accurately and restore the smoothness of the urinary system. It is the ultimate means to deal with stones and the main method to deal with complex stones. It can also be used to treat other diseases such as ureteropelvic junction obstruction and renal pelvis tumors. At present, percutaneous nephrolithotripsy is widely carried out clinically, and the key to the operation is the establishment of the puncture channel. Generally speaking, the general steps of percutaneous nephrocentesis are as follows: 1. Ultrasound or X-ray examination is performed, and the puncture channel is scheduled; 2. Kidney puncture is performed with a renal...
