Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a marking buckle for marking a clinical care position in an operation process and a fixing method thereof.
Background
During surgery, a physician typically marks the site of clinical interest with a titanium clip. Particularly after removal of the tumor, the resection cavity (i.e., the tumor bed) needs to be marked for accurate delivery of subsequent treatments (e.g., radiation therapy). During marking, the titanium clip is placed into the site of interest using a dedicated titanium clip, and then clipped to the adjacent tissue.
For example, breast cancer, breast protection surgery and postoperative radiotherapy become the standard treatment mode of early breast cancer, and in a breast cancer postoperative radiotherapy scheme, accurate delineation of a tumor bed and a target region thereof is of great importance. At present, the tumor bed is mainly drawn according to a metal titanium clip arranged at the edge of an operation cavity, postoperative seroma, postoperative scar and preoperative diagnosis images. The tumor bed target area is mainly obtained by placing a boundary outside the tumor bed.
Post-operative seromas are beneficial to reduce inter-observer variability, but their formation is closely related to the mode of operation and changes dynamically over time, and thus vary widely. The postoperative scar can indicate the tumor bed position, but it is difficult to ensure that the surgical incision is just in the center of the tumor bed in clinic, and the position depth cannot be determined, so the postoperative scar is only a rough indication. The preoperative diagnostic image can provide information of preoperative tumors, and the matching of the preoperative diagnostic image and radiotherapy positioning images is beneficial to delineating a tumor bed, but the matching of the preoperative diagnostic image and the radiotherapy positioning images has certain difficulty due to large difference of the images. The titanium clip mark in the operation cavity is clear and visual, the consistency among observers can be obviously improved, and the titanium clip mark is still considered as a main reference for delineating the tumor bed at present although research reports that the titanium clip mark has the problems of displacement, placement which is not standardized, variability of point-defined three-dimensional boundaries and the like.
While existing titanium clip markers may assist in locating a site of clinical interest (i.e., the tumor bed), several problems remain. Firstly, artifacts exist in postoperative CT and MRI scanning, and particularly, imaging of surrounding normal tissues is obviously interfered in MRI scanning; secondly, the patient exists in the body for a long time after the treatment is finished, so that the tissue fibrosis is easily caused, the recovery and the beauty effect of the patient are influenced, the MRI image which can be reviewed is interfered, and the curative effect judgment is influenced; in addition, because the titanium clip is fixed on the tissue by clipping, the titanium clip can be displaced under the comprehensive action of various factors such as operation traction, postoperative change and the like, so that the positioning is inaccurate. In addition, the titanium clip is made of titanium alloy material, has low rejection with biological tissues, has ductility and elasticity, and can be conveniently fixed at a clinical concerned position, so that no substitute exists in the prior art at present.

The buckle body 10 is also provided with a normally closed elastic clamp body 24 for clamping tissues at a concerned position, and the position of the buckle body 10 can be fixed more conveniently and accurately by matching with the fixation of the threading hole 21 and a suture line. The normally closed elastic clamp body 24 may be provided with a positioning hole or a limiting block, so as to facilitate the normally closed elastic clamp body 24 to be opened and closed by using a surgical instrument.
The threading hole 21 may also be disposed on the clamping arm of the normally closed elastic clamp 24, which is convenient for fixing surgical instruments, and is convenient for fixing with surrounding tissues through suture after the buckle 10 is in place, so as to avoid the possibility of the normally closed elastic clamp 24 being clamped firmly.
The buckle body 10 is made of a biodegradable material which does not generate or has small artifacts, and may be a metal material, a non-metal material, or a composite material which is subjected to special treatment and can reduce or eliminate the artifacts. In actual use, the material types can be selected, compounded or processed in other forms according to requirements.
The button body 10 is preferably a non-metal material to eliminate the influence of metal artifacts, and may be one or more of biodegradable materials such as polyesters, polyurethanes, polyamides, polylactic acids or polyacetic acids, and may be prepared by mixing in proportion in specific applications.
The invention provides a method for fixing a marker buckle for marking a clinical concerned position in an operation process, which fixes the marker buckle for marking the clinical concerned position in the operation process, and comprises the following steps:
the marker buckle is placed at a clinical site of interest, and a surgical needle is used to thread a suture through the threading hole 21, thereby suturing and fixing the marker buckle at the site of interest.
