Embodiment Construction

[0037] The use of the present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0038] Such as figure 2 and image 3 As shown, a ganglion cyst therapeutic apparatus based on the principle of impact dynamics includes a casing 20, a striking device 23, and a launching device 22. The casing 20 and the striking device 23 are coaxially arranged from the outside to the inside. The casing 20 It is set as a hollow cylindrical structure, the outside of the shell 20 is coaxially arranged and sleeved with sleeves 25, the striking device 23 is set as a solid cylindrical structure, the outer diameter of the shell 20 is larger than the inner diameter of the striking device 23, and the rod 26 The striking device 23 and the housing 20 are controlled to move relative to each other, and the initial position of the rear end of the striking device 23 is embedded in the front end of the housing 20 under the action of tension to form impact kinetic ...

Abstract

The invention discloses a tendon sheath cyst treatment instrument based on the principle of impact dynamics, which comprises a shell, a striking device, a launching device, a fixed calibration device, a spring, a sleeve, a pull rod, and an impact head. The hitting device is set as a solid cylinder structure, the outer side of the hitting device is coaxially arranged and covered with a casing, the outer side of the rear end of the central axis of the casing is provided with a sleeve, and the rear end of the hitting device is sleeved along the inner side of the casing. Spring, the rear end of the spring is connected to the rear end of the housing, the front end of the spring is connected to the inner rear end of the striking device; the free end of the pull rod is inserted through the sleeve, the housing and the striking device is connected, and the free end of the striking device An impact head is provided, and the impact head is brought into contact with the ganglion cyst, and the impact kinetic energy is released through the striking device to perform impact crushing treatment. It can better release the impact force and shock wave generated by the striking device. Portable and easy to operate, it can be easily treated even if the ganglion cyst recurs.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a treatment instrument for ganglion cyst based on the principle of impact dynamics. Background technique [0002] Wrist ganglion cyst is a common benign soft tissue mass in the hand. The traditional view is that ganglion cyst is a hand tumor, but in fact it is not a real tumor. Ganglion cyst is composed of cyst wall, pedicle and cyst fluid. The cyst on the back of the wrist is mainly located in the capsule of the dorsal wrist joint in the degenerative lesion area of ​​the scapholunate ligament. There are no true endothelial cells in the cyst, but there are varying numbers of tiny walled cysts. There will be a slight soreness in the affected area, and at the same time, there will be wrist weakness, discomfort or soreness, radiating pain in the affected area, and in severe cases, it will also cause certain dysfunction to the patient. Superficial ganglion cys...
