DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, a pistol-type rotator cuff balloon delivery device in one embodiment of the present invention includes a pistol-type gripping handle 1, a delivery outer tube 2, a delivery inner tube 3, a Luer connector tube 4, and a control assembly 5. The pistol-type gripping handle 1 has a transversely extending accommodating portion 11 and a downwardly extending gripping portion 12, and the interiors of the accommodating portion 11 and the gripping portion 12 together form an accommodating space 13. One end of the delivery outer tube 2 is fixedly connected to one end of the accommodating portion 11; the delivery inner tube 3 is inserted into the delivery outer tube 2 and can move axially within the delivery outer tube 2. One end of the delivery inner tube 3 is arranged in the gripping portion 12 and the other end extends out of the delivery outer tube 2. The other end of the delivery inner tube 3 is provided with a rotator cuff balloon. The Luer connector tube 4 is at least partially arranged in the accommodating portion 11 and fixedly connected to the one end of the delivery inner tube 3. The Luer connector tube 4 is configured to be able to move axially along the accommodating portion 11 and drive the delivery inner tube 3 to move. The control assembly 5 is at least partially disposed in the gripping portion 12 . One end of the control assembly 5 is connected to the Luer connector tube 4 for controlling the axial movement of the Luer connector tube 4 along the accommodating portion 11 .

[0024] The working principle of the pistol-type rotator cuff balloon delivery device is as follows: one end of the delivery inner tube 3, which is provided with the rotator cuff balloon, extends into the area to be filled. Physiological saline is injected into the rotator cuff balloon through the Luer connector tube 4 via the delivery inner tube 3 to inflate the rotator cuff balloon. After the rotator cuff balloon has inflated to the desired size, the injection of physiological saline is stopped. The control component 5 drives the Luer connector tube 4 to cause the delivery inner tube 3 to retreat relative to the delivery outer tube 2. The rotator cuff balloon provided at one end of the delivery inner tube 3 is held against the delivery outer tube 2 and, as the delivery inner tube 3 continues to retreat, eventually detaches from one end of the delivery inner tube 3 and enters the area to be filled, thereby completing the delivery process of the rotator cuff balloon.

[0025] The pistol-type rotator cuff balloon delivery device of the above embodiment is provided with a pistol-type gripping handle 1, which is easier to hold than the straight tube or pen-shaped handles in the prior art, making the pistol-type rotator cuff balloon delivery device easy to operate, thereby improving the accuracy of the surgical operation.

[0026] In one embodiment, if Figure 2 and Figure 3 As shown, the control assembly 5 includes a trigger 51 and a linkage 52. The trigger 51 is rotatably connected to the grip portion 12. For example, a hole 514 may be formed in the lower portion of the trigger 51, and a fixed shaft 123 is disposed within the grip portion 12. The hole 514 in the lower portion of the trigger 51 is sleeved onto the fixed shaft 123, allowing the trigger 51 to rotate clockwise or counterclockwise about the fixed shaft 123. The grip portion 12 has an opening 121 formed vertically therein, and at least a portion of the trigger 51 is disposed outside the grip portion 12 through the opening 121.

[0027] One end of the linkage member 52 is connected to the Luer connector tube 4, and the other end is rotatably connected to the grip portion 12. For example, a fixed shaft 523 is provided at the lower portion of the linkage member 52, and a corresponding hole 122 is also provided in the grip portion 12. The fixed shaft 523 at the lower portion of the linkage member 52 is inserted into the hole 122 and can rotate relative to the hole 122. In one embodiment, the lower middle portion of the linkage member 52 is connected to the trigger 51 and is configured to move the Luer connector tube 4 when actuated by the trigger 51.

[0028] like Figure 3 As shown, the upper portion of the linkage member 52 defines a first sliding groove 521 along its length. The first sliding portion 41 is disposed within the first sliding groove 521 and is configured to move along the first sliding groove 521. For example, in the initial state of the linkage member 52 and the Luer connector tube 4, the upper end of the first sliding groove 521 abuts against the first sliding portion 41. As the trigger 51 drives the linkage member 52 to rotate, relative sliding occurs between the first sliding portion 41 and the first sliding groove 521. The first sliding portion 41 can move from the upper end of the first sliding groove 521 to the lower end of the first sliding groove 521, thereby driving the Luer connector tube 4 and the inner delivery tube 3 to move backward, thereby disengaging the rotator cuff balloon.

[0029] Furthermore, a second sliding groove 522 is defined in the lower middle portion of the linkage member 52, and a second sliding portion 511 is provided on the trigger 51. The second sliding portion 511 is disposed within the second sliding groove 522 and is capable of sliding along the second sliding groove 522. In the initial state of the linkage member 52 and the trigger 51, the second sliding portion 511 abuts against the lower end of the second sliding groove 522, thereby driving the linkage member 52 to rotate when the trigger 51 is rotated. When the trigger 51 is pulled, the second sliding portion 511 abuts against the upper end of the second sliding groove 522, thereby driving the linkage member 52 to move in the opposite direction to when the trigger 51 was pulled when the trigger 51 is reset.

[0030] In one embodiment, a side of the trigger 51 away from the grip portion 12 extends away from the grip portion 12 to form a protrusion 512. The protrusion on the trigger 51 can further improve the grip of the grip portion 12 and prevent the user's hand from moving between the trigger 51 and the grip portion 12 during gripping.

[0031] Furthermore, a limiting wall 513 is provided along the edge of the trigger 51 away from the grip portion 12. The width of the limiting wall 513 is configured to be greater than the width of the opening 121 to ensure that the trigger 51 does not completely enter the grip portion 12 during rotation.

[0032] In one embodiment, if Figure 2As shown, in order to prevent the operator from accidentally depressing the trigger 51 during operation, the upper end of the trigger 51 is provided with a safety pin 6 that can slide relative to the accommodating portion 11. The safety pin 6 is inserted into the accommodating portion 11 and abuts against the upper end of the trigger 51. The safety pin 6 is configured to fix the trigger 51 relative to the holding portion 12.

[0033] Specifically, the safety latch 6 can be positioned so that it is inserted into and slidable within the receiving portion 11. A notch is provided on the safety latch 6. When the trigger 51 is not released, the upper end of the trigger 51 abuts against the safety latch 6, preventing the trigger 51 from being pulled. When the safety latch 6 is released and the safety latch 6 slides within the receiving portion 11, the notch moves to the upper end of the trigger 51, allowing the upper end of the trigger 51 to pass through the notch, allowing the trigger 51 to be pulled.

[0034] The safety latch 6 is further provided with a clamping member 61, which fixes the safety latch 6 to the accommodating portion 11. When the clamping member 61 is removed from the safety latch 6, the safety latch 6 can slide relative to the accommodating portion 11.

[0035] In one embodiment, a balloon protector 7 is provided on one end of the outer delivery tube 2 near the rotator cuff balloon. The balloon protector 7 covers the rotator cuff balloon and is movable along the outer delivery tube 2. During use, the balloon protector 7 and the rotator cuff balloon are introduced together into the area to be filled. The balloon protector 7 then slides along the outer delivery tube 2 to expose the rotator cuff balloon for subsequent filling operations.

[0036] A stopper 8 is disposed between the balloon protector 7 and the receiving portion 11. The stopper 8 is positioned over the outer delivery tube 2 and is configured to be at least partially detachable from the outer delivery tube 2. Specifically, the stopper 8 engages the balloon protector 7 and the outer delivery tube 2, thereby securing the balloon protector 7 relative to the outer delivery tube 2 and preventing unwanted movement of the balloon protector 7 during operation. When the stopper 8 partially detaches from the outer delivery tube 2, it creates space for the balloon protector 7 to move along the outer delivery tube 2.

[0037] In summary, the pistol-style gripping handle 1 of the present invention makes the rotator cuff balloon delivery device easier to operate, thereby improving surgical accuracy. The trigger 51 facilitates controlled detachment of the rotator cuff balloon, while the safety latch 6 prevents accidental operation. The protrusion 512 on the trigger 51 further enhances grip and reduces slippage in the gripping handle 1. Furthermore, the balloon protector 7 effectively prevents damage to the rotator cuff balloon during transportation or use.
