Medullary cavity focus scraping and washing device

Abstract

The invention discloses a medullary cavity focus scraping and washing device. The medullary cavity focus scraping and washing device comprises a scraping and washing pipe body, a first operating rod and a second operating rod; a guide end is connected to the lower portion of the scraping and washing pipe body; furthermore, a scraping and washing window is formed in the position, close to the guide end, of the scraping and washing pipe body; a central partition plate is arranged in the scraping and washing pipe body to equally divide the inner cavity into a first cavity and a second cavity; furthermore, a gap is formed between the central partition plate and the guide end; the first cavity is connected with an aspirator; an aspiration channel is formed in the first cavity; and an eccentric partition plate is arranged in the second cavity to divide the second cavity into a water injection channel and a camera shooting channel. The medullary cavity focus scraping and washing device disclosed by the invention has the advantages that: by means of the scraping and washing device, the focus position in a medullary cavity and whether scraping is thorough or not can be observed conveniently; due to the fact that the two sides of the medullary cavity are wide and the middle of the medullary cavity is narrow, the device in the prior art extends into the medullary cavity and is not prone to swinging, so that some focuses cannot be scraped; the scraping and washing device in the invention can conveniently extend into the medullary cavity; and a scraping and washing plate can extend out of the scraping and washing window and scrape the positions which cannot be scraped by an existing tool.

Description

technical field [0001] The invention relates to the field of orthopedics, in particular to a device for scraping and cleaning medullary cavity lesions. Background technique [0002] Patients with intramedullary cavity infection of the long bones of the extremities are often encountered clinically, especially after the long bone fractures of the extremities undergo intramedullary nailing. In these patients, the intramedullary cavity infection is relatively long, and even diffuses the entire bone marrow cavity. For the treatment of osteomyelitis, the treatment method is as follows: first, the specific medullary cavity drill bit is reamed along the bone marrow cavity, and enters the necrotic site, the lesion is completely removed, washed repeatedly, and the lesion is extracted with a suction device, which is currently the most commonly used method. Treatment methods to achieve the purpose of controlling infection and improving the quality of life of patients. [0003] At prese...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the lesions in the bone marrow cavity are removed by blind scraping with a spatula, and then the pus and scrapings are sucked out with an aspirator. The scraping action can easily cause inflammation to spread up and down in the bone marrow cavity, resulting in incomplete removal of necrotic tissue, and the limited length of the curette, rigid objects, and limited cleaning range, resulting in poor infection control, increased treatment cycles, repeated recurrences, and various The rise of the treatment cost will not achieve a good treatment effect

Moreover, when the current lesion curettage device reaches the lesion position, because the middle of the bone marrow cavity is narrow and the two ends are wide, it is difficult to scrape some lesions.
