Description

Wound curettage device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to wound curettage device.

Background

The sinus wound is a common wound in clinic, generally refers to infection and necrosis of body tissues, and is discharged from the body surface to form a latent blind tube which is opened on the body surface and is not communicated with hollow organs in the body, and can occur in soft tissues, fat, muscles, even bones and the like; the formation of sinus wounds is mainly related to infection, wound infection caused by various reasons is not effectively treated in time, and the surrounding fibrous connective tissue gradually grows and thickens under the stimulation of chronic inflammation, abscess or foreign bodies to form the sinus. If the sinus is not completely removed or foreign bodies and necrotic tissues remain, the sinus can be not healed for a long time or can be repeatedly attacked; the common wounds are abdominal wall sinus wounds caused by poor drainage after infection of abdominal wall incisions or foreign matters left in the incisions, chronic sinus wounds formed by osteonecrosis caused by bone fracture or other reasons, chronic sinus wounds formed by trauma or foreign matter residues after operations, and the like.

In clinic, in the process of treating sinus wounds, the wound surfaces of the sinus wounds are usually cleaned regularly to scrape, such as to scrape infection, secretion, necrotic tissues and the like in deep tissues so as to promote the regeneration of granulation; in the prior art, a curette is usually used as a curette tool, and some curettees are disclosed in the prior art, for example, a tissue debridement curette with scales and capable of being washed disclosed in chinese patent CN 202942478U can measure the depth of a wound surface (i.e. can measure the depth of a sinus wound) in the process of curettage of the wound surface; the multifunctional visible curette disclosed in the Chinese patent CN209996415U has the advantages that a camera is arranged on a key rod, the camera is connected with a display through a wire, a lighting lamp is arranged on one side of a key handle facing to a key head, and the key rod can be folded and stretched to adjust the length of the key rod, so that the curette process can be visible; although the existing curettage key has various functions, the curettage key head serving as a core component of the curettage operation generally adopts a spoon-shaped structure (namely, a curettage groove is arranged), and in the actual use process, because the curettage key head has a certain width, the curettage key head can not rotate in a sinus wound to change the curettage direction, especially when the sinus wound is flat, or a plurality of wound surfaces or the circumferential direction of the sinus wound need to be curetted, the existing curettage key can only be used for curettage of one wound surface, and after one wound surface is curetted, the wound surface can be continuously curetted only after the orientation is readjusted, so that the curettage key is complex in operation, inconvenient to use and low in efficiency, and is not very suitable for comprehensively and uniformly curettage the circumferential direction of the sinus wound, and the healing of the wound is influenced; in addition, the curette head of current curette, owing to adopt spoon column structure, at the in-process of scraping the surface of a wound, be usually at medical personnel's pulling down along direction removal from inside to outside, so that harass from inside to outside and scrape, but in actual operation, because the structure reason of curette head, along with the removal of curette head, the secretion that piles up between curette head and the surface of a wound and necrotic tissue etc. increase gradually, force the interval change of curette head and the surface of a wound, can lead to the scram degree of depth to appear increasing earlier the problem that reduces afterwards usually, lead to harassing and scrape the depth and differ, reach the purpose that does not harass and scrape, treat urgent need to improve.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to improve the not enough that exists among the prior art, provide a compact structure, reasonable in design's wound is scratched and is scraped the ware, not only can effectively harass scrape the intraoral surface of a wound of sinus wound, can follow the comprehensive, even harassment of circumferencial direction moreover and scrape the surface of a wound, and scratch efficiently, can effectively ensure to harass and scrape the degree of depth unanimous basically to effectively solve the not enough that prior art exists.
