Lotus-root-shaped guide locator

Abstract

The invention provides a lotus-root-shaped guide locator and belongs to a medical instrument. The lotus-root-shaped guide locator mainly solves the technical problems that radiation injures operators and the amount of radiation on patients is excessively large in the existing guide pin location technology. According to the technical scheme, the lotus-root-shaped guide locator is characterized by comprising a cylindrical body (1). One end of the cylindrical body (1) is the holding end, and the other end of the cylindrical body (1) is the locating end extending into a human body. The portion, at the port of the locating end, of a through hole is provided with a locating ring (3). The lotus-root-shaped guide locator is mainly applied to guide and location of percutaneous puncture of a guide pin.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a guide needle positioning instrument in an operation. Background technique [0002] The guide needle positioning instrument is a commonly used instrument in the current operation. It is generally a cylindrical body with a through hole. After the positioning end is positioned for a specific point, the guide needle is inserted through the through hole, in order to reach the predetermined value along the through hole. Location. In open surgery, although the above-mentioned positioning operation can be performed in a visible state, the bony surface of the positioning point may not be able to carry the above-mentioned positioning instruments due to various reasons, or during the insertion of the guide needle tip along the only through hole, due to slip and cannot be accurately fixed at the anchor point. [0003] The more important aspect is that with the rapid development of medical minimall...

Problems solved by technology

However, in percutaneous puncture, because it is impossible to see directly, after the positioning of the guide pin device, it is necessary to confirm whether the positioning is correct by X-ray fluoroscopy. Multiple punctures with positioning instruments, multiple X-ray fluoroscopy confirmations, and repeated operations

Even if it is accurately positioned on the skin surface with the help of surface X-ray positioning devices (such as positioning film, etc.), because there is a certain distance between the bony surface of the positioning site and the skin surface, even if the guide pin positioning device in the prior art can accurately position on the skin surface , also due to errors in X-ray fluoroscopy, it is difficult to insert the guide pin on the bone surface through the skin surface and position it accurately at one time. Often, it is necessary to repeatedly adjust the operation under X-ray, or even under continuous X-ray fluoroscopy. operate

Therefore, there is blindness in the guide pin positioning operation carried out by using the above-mentioned guide pin positioning apparatus, and the success rate of one positioning is not high, which wastes precious time in the operation, and the operator and the patient cannot be avoided in the process. Long-term exposure to low-dose radiation can cause fatigue, fatigue, hair loss, insomnia, oral ulcers, leukopenia, and thrombocytopenia, and even low immune function, carcinogenicity, and teratogenicity, which restrict minimally invasive surgery to a certain extent. Rapid development and application of technology
