Embodiment 1

[0036] Such as figure 1 , 2 , 3, a coaxial prostate expansion device, including a catheter 1, the front of the catheter 1 is provided with a balloon 3, the balloon 3 is a high-pressure balloon, driven by pressure can form a predetermined shape and Dimensions, with little or no deformation due to flared objects.

[0037] Such as figure 1 , 2 As shown, the catheter 1 is also covered with a sleeve 7, and when the sleeve 7 slides to the front of the catheter 1, the balloon 3 is completely covered by the sleeve 7; the sleeve 7 slides to the catheter 1 When the rear portion of the balloon 3 is fully exposed.

[0038] Such as figure 1 As shown, the catheter 1 is provided with two marks 10, which respectively correspond to the rear end of the sleeve 7 when the balloon 3 is completely covered and the rear end of the sleeve 7 when the balloon 3 is completely exposed.

[0039] Such as figure 1 As shown, the rear end of the casing 7 is provided with a casing handle 8, and the casin...

Embodiment 2

[0055] This embodiment is an optimization and improvement carried out on the basis of Embodiment 1, specifically as follows:

[0056] Such as Figure 6 , 7 , 8. In this embodiment, the endoscope is used as the sleeve 7 of the first embodiment, and the corresponding size of the endoscope is customized. The endoscope includes an endoscope sleeve 7.1 and an endoscope handle 7.2, and the endoscope handle 7.2 is provided with an endoscope cold light source interface 7.3 and an endoscope eyepiece port 7.4; the inner diameters of the endoscope sleeve 7.1 and the endoscope handle 7.2 need to match the outer diameter of the catheter 1; and the endoscope handle 7.2 The end of the tube is provided with a sleeve lock nut 9, wherein the cooperation mode of the endoscope handle 7.2 and the sleeve lock nut 9 can be the same as that of the sleeve handle 8 and the sleeve lock nut 9 in Embodiment 1 ( Such as Figure 5 ).

[0057] Moreover, the catheter locking bolt 5 provided in the cathete...

Abstract

The invention belongs to the technical field of medical treatment instruments, and specifically relates to a coaxial prostate dilating device. The coaxial prostate dilating device comprises a catheter, wherein a saccule is arranged at the front part of the catheter, and the catheter is further sleeved with a cannula; the saccule is completely coated with the cannula when the cannula slides to thefront part of the catheter; and the saccule is completely exposed outside when the cannula slides to the rear part of the catheter. By virtue of a coaxial catheter design, the coaxial prostate dilating device is formed through coaxial nesting combination of the outer-layer cannula and the catheter, the cannula sleeves the saccule, and the head end of the catheter is integrally linked with the cannula in a smooth transition manner, so that a tube body structure is smooth and is easy to insert.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a coaxial prostate expansion device. Background technique [0002] The prostate is a male-specific gonad organ, an unpaired substantive organ composed of glandular tissue and muscular tissue. The prostate is shaped like a chestnut, with the bottom facing up and close to the bladder, the tip facing down, touching the urogenital diaphragm, the front sticking to the pubic symphysis, and the back sticking to the rectum. The urethra passes through the middle of the prostate gland, guarding the upper opening of the urethra. Therefore, with benign prostatic hyperplasia, urination is first affected. In addition, the prostate is a sex secretion gland that is very rare in the human body and has dual secretion functions of internal and external. As an exocrine gland, the prostate secretes about 2 ml of prostatic fluid every day, which is the main component of semen; as...
