Technical Field
[0001] The invention relates to the technical field of surgical instruments and provides a hemostatic forceps for surgical dressing changes. Background Art
[0002] Surgical dressing change, also known as dressing exchange, includes wound inspection, wound cleaning, removal of pus, secretions and necrotic tissue, and dressing covering, which plays an important role in preventing and controlling wound infection and promoting wound healing. When cleaning a wound, it is necessary to remove foreign matter, necrotic tissue, and secretions from the wound, keep the wound drainage unobstructed, prevent or reduce bacterial reproduction and the absorption of harmful decomposition products and the stimulation of secretions, and when applying local medication to the wound, the inflammation is limited, the growth of granulation tissue and epithelium is promoted, and wound healing is promoted. It requires the coordinated operation of a variety of different surgical instruments, and in order to ensure the cleanliness of the wound and the complete removal of necrotic tissue, multiple disinfection and cleaning are required. However, in order to prevent and control wound infection, it is necessary to minimize the surgical instruments in contact with the wound and the exposure time of the wound. Prior art CN218684588U provides a dressing change forceps, comprising two sets of medical forceps handles, the ends of which are marked with longitudinal scales, the end faces of the rotating swing arms are marked with transverse scales, one of the two sets of medical forceps handles has a flushing tunnel running through the inside of the handles, and the other set of the two sets of medical forceps handles has a sewage tunnel running through the inside of the handles. The prior art can improve the speed of cleaning and disinfecting patient tissue wounds. The inventor believes that the prior art still has a large room for improvement. Summary of the invention
[0003] The purpose of the present invention is to trim the wound, remove the necrotic tissue, wound secretions and residual medicines around the wound, and be able to clamp alcohol cotton balls, wound dressings and other medical supplies to re-dress the wound. Secondly, when the necrotic tissue and wound secretions around the wound are removed, the removed necrotic tissue and wound secretions are drained and cleaned to avoid repeated dumping of medicines and delaying the wound dressing work; a small amount of continuous medication is administered to the wound to reduce drug waste, ensure that the wound is fully disinfected, and the wound is evenly coated with medicines. To this end, the present invention provides a surgical dressing change hemostatic forceps, including a gripping portion, an extension portion and a clamping portion, the extension portion connecting the gripping portion and the clamping portion, the surgical dressing change hemostatic forceps also includes a cleaning mechanism and a cutting mechanism, the side of the clamping portion is provided with a cutting mechanism, one end of the cleaning mechanism is connected to the cutting mechanism, and the other end of the cleaning mechanism is connected to the extension portion. A cutting mechanism is provided on the side of the clamping part, which can scrape and clean a small amount of necrotic tissue, wound secretions and residual medicines at the wound, so as to facilitate the subsequent re-application of medicines and improve the efficiency of wound dressing changes; the cleaning mechanism drains and cleans the necrotic tissue, wound secretions and residual medicines scraped by the cutting mechanism, so as to reduce the workload of wound cleaning; the cleaning mechanism always keeps a clear field of vision at the wound, which is conducive to judging whether the necrotic tissue has been trimmed, avoiding secondary trimming of the wound after wound cleaning, avoiding repeated wound cleaning work and delaying wound dressing changes; the cleaning mechanism continuously administers medicines in small amounts, so as to reduce the waste of cleaning and disinfection drugs.
[0004] Preferably, the surgical dressing-changing hemostatic forceps further comprises a first clamp body and a second clamp body, the first clamp body and the second clamp body are hingedly connected, the excision mechanism comprises a cutting part, the side of the clamping part of the first clamp body is provided with a cutting part, the cutting part is provided with at least one inclined blade, one end of the blade is fixed to the first clamp body as a fixed end, and the other end of the blade is inclined toward the second clamp body. Since the first clamp body and the second clamp body are hingedly connected, the operator scrapes the necrotic tissue, wound secretions and residual medicine at the wound by rotating the inclined blade of the first clamp body; and the other end of the blade is inclined toward the second clamp body, the necrotic tissue, wound secretions and residual medicine scraped by the blade are squeezed by the second clamp body and there is a gap behind the blade, and they will move backward along the shape of the blade to avoid staying at the wound, resulting in the operator being unable to judge whether the necrotic tissue at the wound has been cleaned. Further, when the first clamp body is the surgical dressing-changing hemostatic forceps and the excision mechanism is at the bottom, the clamp body located on the left side is conducive to the operation of the surgical dressing-changing hemostatic forceps, the first clamp body is the active part, and the excision mechanism on the first clamp body trims the wound.
