Description

Technical Field

[0001] The present application relates to the technical field of shock wave therapy apparatus, and more specifically, to an adjustable flow shock wave ballistic body tube. Background Art

[0002] Shock waves were first used in extracorporeal shock wave lithotripsy in clinical medicine. In the late 1980s, extracorporeal shock wave lithotripsy began to be used in orthopedics and rehabilitation therapy. After more than ten years of clinical research, shock wave therapy has been increasingly improved and its application scope has been expanding. As a new treatment method between conservative therapy and surgical therapy, shock waves are popular in Europe and the United States.

[0003] The shock wave ballistic body therapy device is currently used to treat various lesions. The ballistic body tube is an important component of the device and has a decisive influence on the treatment effect. During the use of the existing shock wave ballistic body tube, the side wall of the bullet body and the inner wall of the tube body fit together. During the high-speed reciprocating motion of the bullet body in the tube body, a positive or negative pressure cavity will be formed on both sides. The traditional ballistic body structure will open a small circular hole at the front end of the tube, that is, near the air inlet. When the bullet body moves backward, the gas will enter the tube body from the small circular hole. The position and size of the small circular hole need to be repeatedly verified and debugged to achieve the best impact effect. The existing tube structure cannot adjust the air intake according to the needs of different scenarios during use, and there are certain limitations in use. Utility Model Content

[0004] In order to solve the above problems, the present application provides an adjustable flow shock wave ballistic body tube.

[0007] Furthermore, the length of the air hole adjustment groove is 3-5 times the inner diameter of the air inlet hole, and the width is 0.5-0.1 times the inner diameter of the air inlet hole.

[0008] Furthermore, the length of the adjusting nut is greater than the length of the air hole adjusting slot.

[0019] Embodiment 1:

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The embodiment of the present application discloses an adjustable flow shock wave trajectory body tube, comprising a pipe body 1, a bullet body 2 is slidably connected inside the pipe body 1, an air inlet 3 for connecting high-pressure gas and a pipe mounting thread 4 for connecting to a shock wave transmission body are provided at the rear end of the pipe body 1, an adjusting thread section 5 is provided on the front end outer wall of the pipe body 1, an air hole adjusting groove 6 is penetrated through the middle of the adjusting thread section 5, and a matching adjusting nut 7 is threadedly connected to the adjusting thread section 5.

[0022] See also Figure 1-2 The length of the air hole adjustment groove 6 is 3-5 times the inner diameter of the air inlet hole 3, and the width is 0.5-0.1 times the inner diameter of the air inlet hole 3.

[0023] See also Figure 1-2 , the length of the adjusting nut 7 is greater than the length of the pore adjusting slot 6.

[0024] As a further preference of this embodiment, the pitch of the adjusting thread segment 5 is 0.3-0.8 mm, and the thread depth is 0.3-0.8 mm, which can effectively improve the adjustment accuracy and connection sealing.

[0025] The implementation principle of an adjustable flow shock wave ballistic body tube in the embodiment of the present application is:

[0026] High-pressure gas enters the pipe body 1 through the air inlet 3, thereby driving the bullet body 2 to make high-speed reciprocating motion in the pipe body 1. The bullet body 2 hits the shock wave transmission body at the rear end of the pipe body 1, thereby continuously releasing medium and high frequency shock waves to the human body to achieve a therapeutic effect.

[0027] The side wall of the bullet body 2 fits with the inner wall of the pipe body 1. During the high-speed reciprocating motion of the bullet body 2 in the pipe body 1, a positive pressure or negative pressure cavity will be formed on both sides. The present application designs a long strip of air hole adjustment groove 6 at the front end of the pipe, and is equipped with an adjusting threaded section 5 on the outside. An adjusting nut 7 with a matching internal thread can be rotatably fixed to the front end of the pipe body 1. By rotating the adjusting nut 7, the long strip of air hole can be covered to different degrees. Through this principle, the position of the air inlet point relative to the pipe body 1, the air inlet area and other parameters can be quickly adjusted to meet the needs of different scenarios, thereby realizing the rapid control of the output power, movement speed and other parameters of the bullet body 2 by the shock wave therapy device body.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
