However, it is usually found during the resection operation that there are residual stones with a large particle size, which cannot be successfully separated out or that untreated stones need to be treated again. Surgery on the urethra, which requires repeated operations in special cases
The biggest disadvantage of this operation method is:

Embodiment Construction

[0017] Such as figure 1 As shown, the tissue pulverization and lithotripsy mirror of this embodiment includes an operation tube 2 with an operation channel arranged in the axial direction, an endoscope 1 and a lighting channel 3 arranged on the operation tube, and also includes a detachable sleeve The mirror sheath 4, which is located in the front section of the operation tube and can be used in conjunction with the resectoscope, especially the interface part of the mirror sheath, can be used in conjunction with the operation tube of the present invention, and can also be used in conjunction with the port of the existing resectoscope; Of course, the structure of the mirror sheath can also be the same as that of the existing resectoscope, specifically, it can be connected by means of threads or buckles. It is convenient to assemble, disassemble and replace. A water passage 6 is formed between the outer wall of the operating tube and the inner wall of the mirror sheath. The radi...

Abstract

The invention discloses a tissue morcellation lithotriptoscope which comprises an operation pipe, an endoscope, a lighting channel and a scope sheath, an operation channel is axially arranged on the operation pipe, the endoscope and the lighting channel are arranged on the operation pipe, the scope sheath is detachably sleeved on the front section of the operation pipe and can be matched with a resectoscope, a water passing channel is formed between the outer wall of the operation pipe and the inner wall of the scope sheath, and a water inlet channel communicated with the water passing channel is axially arranged on the wall of the operation pipe. Firstly, by the aid of the tissue morcellation lithotriptoscope, only the scope sheath needs to be inserted into a urethra once in the whole surgery process, multiple injuries of the urethra due to the fact that instruments such as the resectoscope and the lithotriptoscope repeatedly enter the urethra are avoided, and the amount of bleeding is greatly reduced. Secondly, 1/3-1/2 surgical time can be saved in the whole surgery process, the labor intensity of doctors is greatly relieved, and the risk and the pain of a patient are greatly reduced. Thirdly, morcellated tissues and broken stones can be simultaneously exenterated by the aid of different water circulation, and a novel surgical operation mode is developed.

Description

technical field [0001] The invention relates to a medical device, in particular to a multi-tissue comminution and lithotripsy mirror for urinary system surgery. Background technique [0002] Urinary system stones, prostatic hypertrophy and hyperplasia are common diseases with high incidence in middle-aged and elderly men. One of the effective methods of processing calculi in the prior art is to adopt a lithotripsy machine (also known as a pulverizer) to pulverize the calculus and suck them out. Surgical resection for prostatic hypertrophy and hyperplasia is the most effective treatment method. The multi-functional prostate surgical mirror, which was invented by the inventor in 2010 and obtained patent protection with the patent number 201010000543.5, is widely used clinically due to its advantages of high efficiency. [0003] For patients with stones, prostatic hypertrophy and hyperplasia at the same time, it usually needs to be managed and treated in one operation. The tr...
