Instrument for treating cyst of tendon sheath

Abstract

The invention relates to the technical field of medical instruments, in particular to an instrument for treating the cyst of the tendon sheath. The instrument comprises a suction tube and a dosing tube, the suction tube and the dosing tube are fixedly connected in parallel, and a cannula is arranged at the head end of the suction tube; a liquid discharging tube is arranged on the side wall of the head end of the suction tube, open-close structures are arranged in the cannula and the liquid discharging tube, and a sealing cover is in screw joint to the tail end of the dosing tube. According to the instrument, a dual-channel puncture needle is arranged at the free end of a liquid suction tube, a connection tube is communicated with a channel in the dual-channel puncture needle, the head ends of a first piston rod and a second piston rod are correspondingly located in the suction tube and the dosing tube respectively, and the first piston rod is provided with a first rubber plug; a second piston rod is provided with a second rubber plug, the other end of the first piston rod is located outside the suction tube, the other end of the second piston rod penetrates through the sealing cover and extends to the exterior of the dosing tube, and the other end of the first piston rod and the other end of the second piston rod are provided with the same handle. According to the instrument, the area of a wound is greatly reduced, infection is avoided, and the surgery efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an appliance for treating ganglion cysts. Background technique [0002] Ganglion cyst is a cystic mass that occurs in the tendon sheath of a joint, a condition caused by degeneration of connective tissue around the joint capsule. Cysts contain colorless transparent or orange, light yellow thick mucus, mostly in the dorsum of the wrist and dorsum of the foot. Using puncture to extract the cystic fluid, and then injecting adjuvant therapy drugs, such as corticosteroids or hyaluronidase, has a certain effect on the treatment of ganglion cysts, and the trauma is small. However, since the existing apparatus generally adopts the method of extracting the cystic fluid first, and then injecting the medicine for auxiliary treatment, it is impossible to inject the medicine for auxiliary treatment or the soluble medicinal liquid for ablation of the cystic fluid while pumping the ...

Problems solved by technology

However, since the existing apparatus generally adopts the method of extracting the cystic fluid first, and then injecting the medicine for adjuvant treatment, it is impossible to inject the medicine for adjuvant treatment or the soluble medicinal liquid for ablation of the cystic fluid while pumping the fluid, thus resulting in the need for multiple injections. Step operation, low treatment efficiency
