Description

Technical Field

[0001] This utility model relates to the technical field of accessories for pneumatic ballistic extracorporeal shock wave therapy devices, and in particular to a shock wave handle with a retractable treatment head. Background Technology

[0002] Pneumatic ballistic extracorporeal shock wave therapy utilizes the energy generated by high-pressure gas to drive a projectile within a handle. This projectile impacts the treatment head in a pulsed manner, allowing energy waves to penetrate the body tissue for treatment. However, the projectile's impact on the treatment head also reflects off the handle. If the treatment session is prolonged, this recoil can cause numbness and tingling in the user's hand, making it difficult to aim at the treatment area. Existing shock wave handles do not overcome this recoil issue. Therefore, existing shock wave handles all suffer from the weakness of not being able to sustain prolonged treatment.

[0009] Furthermore, a buffer pad is provided inside the vertical sliding hole to cushion the bullet.

[0010] Furthermore, the upper end of the outer sleeve is connected to the lower end of the solenoid valve seat, and the middle and lower parts are vertically slidably engaged with the lower inner sleeve.

After the bullet exceeds the side hole A, the high-pressure airflow below the bullet slowly leaks out from the gap between the treatment head and the lower end of the outer tube through the connecting cavity and the side hole B, so that the bullet can achieve reciprocating impact.

[0029] The lower end of the solenoid valve seat 3 is provided with an upper limit spring groove 32 that matches the buffer spring 6; the upper end of the outer sleeve 7 is provided with a lower limit spring groove 71 that matches the buffer spring 6; the upper end of the buffer spring 6 abuts against the bottom of the upper limit spring groove 32; the lower end of the buffer spring 6 abuts against the bottom of the lower limit spring groove 71; the upper limit spring groove 32 and the lower limit spring groove 71 provide horizontal limits for the buffer spring 6 to prevent the buffer spring 6 from being misaligned.

[0030] The retractable shockwave handle of the treatment head also includes an inner sleeve; the inner sleeve includes an upper inner sleeve 81 and a lower inner sleeve 82 that are threaded together; the upper end of the upper inner sleeve 81 is slidably engaged with the vertical sliding hole 31, and the lower end is provided with a protruding ring 811 that abuts against the lower end of the buffer spring 6; the lower inner sleeve 82 is slidably engaged with the outer sleeve 7; the lower end of the lower inner sleeve 82 is connected to the treatment head 5; the inner sleeve forms a detachable structure, which is convenient for on-site assembly.

[0031] A buffer pad 311 is provided inside the vertical sliding hole 31 to buffer the bullet body 1.

[0032] The buffer pad 311 is attached to the bottom of the vertical sliding hole 31 to ensure that the buffer pad 311 is in a fixed position in the vertical sliding hole 31 and stabilize the buffering effect of the buffer pad 311.

[0033] The upper end of the outer sleeve 7 is connected to the lower end of the solenoid valve seat 3, and the middle and lower parts are vertically slidably engaged with the lower inner sleeve 82. The lower end is provided with a sliding hole 72 that is vertically slidably engaged with the treatment head 5. The sliding hole 72 is slidably engaged with the treatment head 5 to provide guidance for the vertical sliding of the treatment head 5.

[0034] The retractable shockwave handle of the treatment head also includes a two-way connector 9; the main body of the two-way connector 9 is tubular, with a partition 91 in the middle; the partition 91 has a through hole 911 in the center that matches the trajectory 4; the lower end of the lower inner sleeve 82 and the lower end of the trajectory 4 are both inserted into the upper end of the two-way connector 9; the trajectory 4 communicates with the through hole 911; the treatment head 5 is connected to the lower end of the two-way connector 9; the lower end of the lower inner sleeve 82 has a connecting cavity 821 in the center; the partition 91 has a connecting hole 912; the connecting hole 912 is located between the trajectory 4 and the lower inner sleeve 82; the lower end of the trajectory 4 has a side hole A 41 that communicates with the connecting cavity 821; the lower end of the connecting hole 912 has a vent groove 913 that intersects with the through hole 911; when the bullet 1 falls onto the treatment head 5, the high-pressure airflow passes through sequentially. Side hole A 41, connecting cavity 821, and connecting hole 912 reach below partition 91; from below partition 91, through ventilation groove 913, it enters through hole 911, pushing bullet 1 to rebound; the lower end of the inner sleeve 82 is provided with side hole B 822 communicating with connecting cavity 821; the diameter of side hole A 41 is greater than the diameter of side hole B 822; in the initial stage of bullet 1 rebound, before bullet 1 exceeds side hole A 41, the high-pressure airflow above bullet 1 is squeezed to below through hole 911, increasing the rebound power of bullet 1; after bullet 1 exceeds side hole A 41, the high-pressure airflow below bullet 1 slowly leaks out from the gap between treatment head 5 and lower end of outer sleeve 7 through connecting cavity 821 and side hole B 822, so that bullet 1 can achieve reciprocating impact.

[0035] There are several connecting holes 912, which are distributed circumferentially around the connecting hole 911, so that the high-pressure gas can reach the bottom of the partition 91 evenly.

[0036] The lower end of the connecting cavity 821 is flared to allow the high-pressure airflow from the side hole A 41 to enter the upper end of the bidirectional connector 9 evenly.

[0037] The working process of this embodiment is as follows: The treatment head 5 is placed against the treatment site on the human body, and the buffer spring 6 is appropriately extended and retracted; then, the solenoid valve 2 intermittently delivers high-pressure gas to the ballistic trajectory 4 through the solenoid valve seat 3; the high-pressure gas pushes the bullet 1 in the ballistic trajectory 4 and impacts downward; the bullet 1 impacts the treatment head 5 along the ballistic trajectory 4; the recoil force generated by the impact acts on the solenoid valve seat 3 through the buffer spring 6; the buffer spring 6 can alleviate the recoil force; the side hole A 41 on the ballistic trajectory 4 is too small, when the bullet 1 continues to fall beyond the side hole A 41, the amount of high-pressure gas pushing the bullet 1 downward is greater than the amount of high-pressure gas entering the connecting cavity 821 through the side hole A 41; when the bullet 1 hits the treatment head 5, the high-pressure gas cannot continue to push the bullet 1 downward, and all the high-pressure gas rushes into the connecting cavity 821 through the side hole A 41. At this time, solenoid valve 2 stops supplying high-pressure gas to solenoid valve seat 3 and connects to the outside; bullet 1 rebounds and moves upward along trajectory 4; the remaining high-pressure gas in the connecting cavity 821 reaches below partition 91 through connecting hole 912, and then pushes bullet 1 back through through hole 911; assisting the upward movement of bullet 1; during the upward movement of bullet 1 and approaching side hole A 41, some of the high-pressure gas in trajectory 4 is squeezed into the connecting cavity 821, which in turn becomes an assist to push bullet 1 upward; after bullet 1 moves upward past side hole A 41, the high-pressure gas above bullet 1 in trajectory 4 enters the outside air through solenoid valve 2; the high-pressure gas below bullet 1 in the connecting cavity 821 and trajectory 4 slowly leaks out from the gap between treatment head 5 and lower end of outer tube 7 through the connecting cavity 821 and side hole B 822.
