Self-suction type sac cavity flusher

Abstract

The invention relates to the field of medical instruments and particularly discloses a self-suction type sac cavity flusher which comprises a flushing suction head part and a handheld part. The handheld part comprises a pushing mechanism, a bottle body and a suction mechanism; the bottle body is provided with a variable-volume flushing chamber and a suction chamber, and the side wall of the flushing chamber is provided with a closable liquid inlet; the flushing suction head part is connected with the bottle body, the flushing suction head part comprises a suction channel communicated with thesuction cavity and a flushing channel communicated with the flushing cavity, the pushing mechanism changes the volume of the flushing cavity by relying on an external force, and a flushing valve onlyallowing liquid to enter the flushing channel from the flushing cavity is fixed in the flushing channel; the suction mechanism changes the volume of the suction chamber by relying on the external force. The self-suction type sac cavity flusher can discharge flushing liquid, food residues, keratoses and the like at the deep part of the sac cavity and promote rehabilitation of affected parts.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of dental medical instruments. Background technique [0002] Clinically common large-scale cystic lesions of the jaw include odontogenic keratocyst, cystic ameloblastoma, odontogenic cyst, etc. Since they are asymptomatic at the beginning of their onset, it is difficult to detect them in time. To a certain extent, or when X-rays are required due to dental disease, it is discovered. The lesion often causes obvious expansion of the mandible, severe absorption and deformation of the cortical bone, serious destruction of the jaw bone, and displacement and rotation of the teeth, resulting in disordered occlusal relationship. At present, for large cystic lesions of the jaw, fenestration decompression combined with cyst plug (denture type) is often selected for treatment. [0003] Fenestration decompression is to open a window on the surface of the cystic lesion of the jaw,...

AI Technical Summary

Problems solved by technology

However, after the patient eats after the operation, food residues are still easy to enter the cyst cavity from the gap between the cyst plug and the cyst cavity, resulting in contamination, infection and even oral mucosal diseases, so the patient needs to remove the cyst plug 2 to 3 times a day , and flush the cyst cavity, flush out food residues and keratinization, and keep the cyst cavity clean to avoid infection

[0004] At present, it is generally recommended that patients use syringes (without sharp needles) or ear washing balls to flush the cyst cavity in clinical practice. However, because the cyst cavity is deep, and it is easy to leave solution and food residues in the deep part, it is difficult to discharge, even if the patient lowers the head sideways as much as possible. All drained, causing residual solution and food debris to pool in cavity

Residual food residues, keratin and solutions that are not completely discharged will become a "hotbed" for bacterial growth, causing local infection, and will also affect the growth of epithelial cells on the surface of the cyst cavity, which may eventually delay the growth of jaw bone, which is not conducive to the recovery of the affected area
