WX-shaped hard endoscopic forceps

Abstract

The invention relates to a medical device-a pair of WX-shaped hard endoscopic forceps, which is used for treating diseases such as lithangiuria, and for treating a children ureteral calculus patient. The diameter of a pair of lithotomy forceps is processed to be about 1.0MM; a calculus can be directly removed by a 4 / 6.5FR children ureteroscope; the surgical calculus removal time is shortened; and the probability of infecting and damaging a ureter is reduced. The outer surface of the pair of WX-shaped hard endoscopic forceps is smooth and round; a rod part is straight; defects such as sharp edges, burrs and cracks are not allowed; opening and closing of forceps heads can be easy, flexible, non-resistance and light, and are not clamped; a forceps petal hardness value of the forceps heads is (400-530)HV0.2; a roughness parameter Ra of the surfaces of the forceps heads is not greater than 0.2 micrometers; the forceps heads, a tube body and a handle are made of materials meeting a requirement of GB / T 1220-2007 Stainless Steel Rod; and the materials can meet a requirement of biocompatibility.

Description

Technical field: [0001] The invention relates to a medical device for treating urinary calculus diseases. Background technique: [0002] Seminal vesiculoscopic minimally invasive technology is the latest international medical achievement in the treatment of blood sperm, azoospermia, infertility and other male difficult diseases. The seminal vesicle can enter the seminal vesicle through the ejaculatory duct, and check the seminal vesicle and ejaculatory duct retrogradely along the normal anatomical path of the seminal tract. If any lesion is found, it can be treated under the laparoscope at the same time. If it is a calculus, it can be taken out with lithotripsy forceps under the seminal vesicle microscope. It has the characteristics of convenient operation, direct observation, and sure effect, and has become a new weapon for diagnosis and treatment. [0003] Ureteroscopic lithotripsy is a very mature minimally invasive procedure in adult urology. Most clinically, holmium l...

AI Technical Summary

Problems solved by technology

Most clinically, holmium laser or pneumatic lithotripsy is used. At present, this technology is rarely used in children with ureteral calculi in China. The main reason is that children’s urinary system is extremely small, and their kidneys and ureters are very fragile. , and children have weak constitutions, high incidence of metabolic diseases, and poor tolerance to surgery. This type of surgery is very risky for children and urologists. Stones with a diameter of less than 1cm and a smooth shape are often There is a possibility of self-discharge, but stones with a diameter greater than 1 cm or less round shape tend to stay in the ureter, causing hydronephrosis and even affecting renal function
