[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5 , a puncture device for thoracic surgery, including a liquid extraction cylinder 1. A liquid extraction rod 2 is slidably connected to the inner wall of the liquid extraction cylinder 1. A liquid suction needle 3 is movably sleeved at the bottom of the liquid extraction cylinder 1. A connection sleeve 5 is movably sleeved on the outer wall of the bottom of the liquid extraction cylinder 1. An adjustment ring 10 is provided on the outer edge of the connection sleeve 5. A connecting rod 12 is fixedly assembled at the bottom of the adjustment ring 10. A round rod 13 is fixedly assembled at the bottom of the connecting rod 12. When in use, at this time, the adjustment ring 10 and the tip of the liquid suction needle 3 are in the same plane. By rotating the adjustment ring 10, the connecting rod 12 and the round rod 13 are rotated on the connection sleeve 5, so that the distance between the adjustment ring 10 and the tip of the liquid suction needle 3 can be adjusted. When there is a distance between the adjustment ring 10 and the liquid suction needle 3, the liquid suction needle 3 can be inserted into the accumulated liquid in the patient's chest. Then, by pulling the liquid extraction cylinder 1, the accumulated liquid is sucked into the liquid extraction cylinder 1 through the liquid suction needle 3. During extraction, at this time, the round rod 13 is in contact with the patient's skin, so that the round rod 13 can reduce the shaking of the liquid suction needle 3 and relieve the patient's pain.

[0022] In a preferred embodiment, an anti-rotation groove 4 is opened on the outer wall of the bottom of the liquid extraction cylinder 1. A slider 6 is slidably connected to the inner wall of the anti-rotation groove 4. The slider 6 is installed on the inner wall of the connection sleeve 5. By the cooperation of the slider 6 and the anti-rotation groove 4, when the adjustment ring 10 rotates, the adjustment ring 10 will not drive the connection sleeve 5 to rotate. By the movable connection between the liquid extraction cylinder 1 and the connection sleeve 5, after the liquid extraction cylinder 1 is used, by pulling the connection sleeve 5 off the liquid extraction cylinder 1, the liquid extraction cylinder 1 can be discarded, and the connection sleeve 5, the adjustment ring 10, the connecting rod 12, the round rod 13 and the contact plate 15 can be used continuously.

[0023] In a preferred embodiment, a thread ring 7 is provided on the outer edge of the connection sleeve 5. The inner wall of the adjustment ring 10 is threadedly connected to the outer edge of the thread ring 7. By the threaded connection between the connection sleeve 5 and the adjustment ring 10, the adjustment ring 10 can rotate on the connection sleeve 5. By positioning the adjustment ring 10 through the thread ring 7, the adjustment ring 10 can be adjusted to a suitable position.

[0024] In a preferred embodiment, anti-slip grooves 11 are formed on the outer edge of the adjusting ring 10. A plurality of anti-slip grooves 11 are provided, and the plurality of anti-slip grooves 11 are evenly distributed on the adjusting ring 10. Through the arrangement of the anti-slip grooves 11, when the user rotates the adjusting ring 10, the user's hand can be inserted into the anti-slip grooves 11 to increase the friction force, so that the adjusting ring 10 can be rotated better.

[0025] In a preferred embodiment, vertical grooves 8 are formed on the outer edges of the connecting sleeve 5 and the threaded ring 7. Scale lines 9 are engraved on the outer edge of the vertical grooves 8. By means of the arrangement of the vertical grooves 8, the shape of the vertical grooves 8 is quite different from that of the threaded ring 7 when viewed from the outside, which is convenient for the user to observe the scale lines 9 on the vertical grooves 8. When the bottom of the adjusting ring 10 corresponds to the numbers on the scale lines 9, this is the distance between the round rod 13 and the tip of the liquid suction needle 3 at this time, so that the liquid suction needle 3 can be inserted into the appropriate effusion position of the patient.

[0026] In a preferred embodiment, a clamping ring 14 is clamped on the outer wall of the round rod 13. A contact plate 15 is fixedly assembled at the bottom of the clamping ring 14. The diameter of the contact plate 15 is larger than that of the round rod 13. Through the arrangement of the contact plate 15, the contact plate 15 can be in contact with the patient's skin, so that the contact area between the contact plate 15 and the patient's skin is relatively large, and no pain will occur at the contact area between the contact plate 15 and the patient's skin. The contact plate 15 is connected to the round rod 13 through the clamping ring 14, so that the contact plate 15 can be removed from the round rod 13, which is convenient for the disinfection treatment of the contact plate 15.

[0027] Working principle: When in use, at this time, the positions of the round rod 13 and the tip of the liquid suction needle 3 are in a parallel state. Then, by rotating the adjusting ring 10, the adjusting ring 10 rotates in the threaded ring 7 on the connecting sleeve 5. The adjusting ring 10 drives the connecting rod 12, the round rod 13 and the contact plate 15 to move upward. By observing the position of the scale line 9 corresponding to the bottom of the adjusting ring 10 and adjusting to the appropriate position, at this time, the distance between the round rod 13 and the tip of the liquid suction needle 3 is the position required to be inserted into the patient's effusion area. The liquid suction needle 3 is inserted into the patient's effusion area, so that the contact plate 15 will be in contact with the patient's skin. The contact plate 15 plays a limiting role and can prevent the liquid suction needle 3 from shaking. Then, by pulling the pumping cylinder 1, the effusion is sucked into the pumping cylinder 1 through the liquid suction needle 3. Then, the liquid suction needle 3 is pulled out. By pulling the connecting sleeve 5 off the pumping cylinder 1, then a new pumping cylinder 1 is inserted into the connecting sleeve 5, and at the same time, the contact plate 15 is removed from the round rod 13 for disinfection treatment.

[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
