Tophus positioning and melting surgery method based on endoscope

Abstract

The invention provides a tophus positioning and melting surgery method based on an endoscope. The tophus positioning and melting surgery method comprises the following steps of firstly guaranteeing that a patient does not take uric acid reducing medicines and does not gout acute attack within 1 month before a surgery; determining surgery positions through conferring with the patient before surgery, and performing marking before the surgery, wherein the number of the surgery positions of the patient is at least 3 and at most 6; selecting nerve block anaesthesia or epidural anesthesia, and performing anaesthesia on the surgery positions, including brachial plexus anaesthesia, lumbar anesthesia and general anaesthesia; based on the endoscope, adopting a straight, curved or S-shaped notch at the center of a longitudinal axis of an enclosed mass, cutting off and scrapping off tophus and crystals deposited at a surgery region, eliminating fallen cartilage slices and other free bodies, trimming degraded tissue, treating residual cartilage and bone defects, flushing the surgery region with a 5% sodium bicarbonate solution, and placing a drainage device; and during dressing change after 48-72h after surgery, drawing out the draining device, and performing extrusion to remove a peripheral remaining slurry mixture of urate and hematocele. The whole surgery is small in wound, few postoperative complications exist, and joint functions are quick to recover.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an endoscope-based tophi localization and ablation operation method. Background technique [0002] Gouty arthritis is a common disease, which is caused by the excessive production or insufficient excretion of uric acid in the body, which leads to the deposition of uric acid in the form of sodium salt in the articular cartilage in the body, thereby causing an inflammatory reaction of tissue foreign bodies. In recent years, with the improvement of quality of life, the incidence of gouty arthritis has been on the rise. For patients with a short course of disease and mild symptoms, medical treatment can achieve good curative effect, while for patients with a long course of disease and obvious gout stone formation, surgical treatment can only be used. [0003] Traditional surgical treatment includes open tophus resection, cleaning, irrigation, curettage and other methods, and the su...

AI Technical Summary

Problems solved by technology

[0003] Traditional surgical treatment includes open tophi resection, cleaning, irrigation, curettage and other methods, the surgical trauma is large

In addition, even if the tophi is removed very thoroughly, there will still be urate residues in varying degrees, especially in surgical treatment, through observation of a large number of patients, it is found that the tophi of patients with severe gout has infiltrated into the tissue, as in The cream seeps into the cake, and unless the tissue is completely removed, this part of the gout stone cannot be removed by surgery

Therefore, the surgical treatment plan in the prior art is usually better for gout stones with less adhesion to surrounding tissues, but for gout stones with more infiltration into the surrounding tissues and more adhesion with the surrounding tissues, the surgical effect is not good. Moreover, due to the large incision and easy infection, patients have many postoperative complications and slow recovery of joint function.
