[0002] Puncture refers to a diagnostic and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for imaging examination, or inject drugs into the body cavity.
[0003] Most of the existing puncture devices use a needle to pierce the human body cavity, and the accumulated fluid in the body cavity is extracted out of the body through a hose or drainage tube connected to the needle and collected in a liquid storage bottle; however, during the drainage process of the accumulated fluid, as the accumulated fluid is discharged, the internal muscles of the body cavity will contract, and the muscles are easily in contact with the needle during contraction, causing the needle to damage the body, which has certain disadvantages. Therefore, there is an urgent need for a puncture device that is easy to operate to solve the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, the utility model discloses a puncture device that is easy to operate. The technical solution adopted is that it includes a grip rod and a needle. The needle is connected to the bottom of the grip rod, and an inner tube is also provided inside the grip rod. The inner tube is slidably connected to the grip rod and the needle. A rotating wheel for driving the inner tube is also provided on the top of the grip rod. The inner tube is connected to a liquid storage bottle through a connecting tube. The needle is arranged on the grip rod. Medical staff can perform puncture operations on patients through the grip rod and the needle to discharge the accumulated fluid in the patient's body.
[0005] As a preferred technical solution of the utility model, the inner tube includes a threaded section, a sliding section and a liquid collection section. The threaded section, the sliding section and the liquid collection section are connected in sequence and are internally connected. The inner tube is arranged in the grip rod and the needle and is driven by a rotating wheel. After the puncture operation is completed, the inner tube can be protruded from the needle through the rotating wheel to drain the accumulated fluid, thereby avoiding the problem of the patient's muscles tightening and contacting with the needle, which may cause injury to the patient.
[0006] As a preferred technical solution of the utility model, the outer diameter of the liquid collection section matches the inner diameter of the needle.
[0007] As a preferred technical solution of the utility model, a threaded hole meshing with the threaded section is provided at the center of the rotating wheel, a sliding groove for the sliding section to slide is provided inside the grip rod, and a limiting mechanism for the rotating wheel is also provided on the grip rod. The limiting mechanism for the rotating wheel is provided on the grip rod, and the grip rod can be limited by a pin in the limiting mechanism to prevent the rotating wheel from rotating during the puncture process, causing the needle tip to protrude from the inner tube and affecting the puncture operation.
[0008] As a preferred technical solution of the utility model, the limiting mechanism includes a pin and a spring, a slideway is provided on the handle, the pin is slidably connected in the slideway, the spring is further provided between the pin and the handle, and a slot matching the size of the pin is further provided on the rotating wheel.
[0009] The beneficial effects of the utility model are as follows: by arranging a needle on the grip, the medical staff can perform puncture operations on the patient through the grip and the needle to discharge the accumulated fluid in the patient's body; an inner tube is arranged in the grip and the needle and is driven by a rotating wheel. After the puncture operation is completed, the rotating wheel can be used to make the inner tube protrude from the needle to drain the accumulated fluid, thereby avoiding the problem that the patient's muscles tighten and contact with the needle, causing injury to the patient; a limiting mechanism for the rotating wheel is arranged on the grip, and the grip can be limited by a pin in the limiting mechanism, thereby avoiding the rotation of the rotating wheel during the puncture process, causing the inner tube to protrude from the needle and affecting the puncture operation.

[0016] Example 1
[0017] like Figures 1 to 4As shown, the utility model discloses a puncture device that is easy to operate. The technical solution adopted is that it includes a grip rod 2 and a needle 3. The bottom of the grip rod 2 is connected to the needle 3. In order to avoid the problem that the needle 3 contacts the patient due to the reduction of fluid accumulation in the patient's body, causing damage to the patient, an inner tube 8 is also provided inside the grip rod 2. The inner tube 8 includes a threaded section 81, a sliding section 82 and a liquid collection section 83. The threaded section 81, the sliding section 82 and the liquid collection section 83 are connected in sequence and are internally connected. The inner tube 8 is slidably connected to the grip rod 2 and the needle 3. The outer diameter of the liquid collection section 83 matches the inner diameter of the needle 3. The inner tube 8 is connected to a liquid storage bottle through a connecting tube 7.
[0018] In order to smoothly perform the puncture operation on the patient, a rotating wheel 1 for driving the inner tube 8 is also provided on the top of the handle 2. A threaded hole 9 engaged with the threaded section 81 is provided at the center of the wheel 1. A sliding groove 11 for the sliding section 82 to slide is provided inside the handle 2. The cross section of the damaged sliding section 82 is rectangular.
[0019] In order to avoid accidental touching of the rotating wheel 1 and causing the inner tube 8 to protrude from the needle 3, the handle 2 is further provided with a limiting mechanism for the rotating wheel 1. The limiting mechanism comprises a bayonet 4 and a spring 6. A slideway 5 is provided on the handle 2, in which the bayonet 4 is slidably connected. The spring 6 is further provided between the bayonet 4 and the handle 2. The rotating wheel 1 is further provided with a slot 10 matching the size of the bayonet 4.
[0020] The working principle of the utility model is as follows: when in use, the medical staff holds the grip 2, directs the needle 3 toward the patient, performs the puncture operation, inserts the end of the needle 3 into the accumulation of fluid in the patient's body, pushes the latch 4 downward to make it slide in the slide 5, the spring 6 is compressed, and the latch 4 slides out of the latch groove 10 on the rotating wheel 1, releasing the limit on the rotating wheel 1, and the medical staff can rotate the rotating wheel 1, and the threaded hole 9 is engaged with the threaded section 81 on the inner tube 8 to drive the inner tube 8 to move downward, and the sliding section 82 of the inner tube 8 slides in the slide groove 11 in the grip 2, so that it will not drive the inner tube 8 to rotate with the rotation of the rotating wheel 1, so that the liquid collection section 83 of the inner tube 8 protrudes from the needle 3, and the accumulated fluid in the patient's body is drained, and collected in the fluid collection bottle through the connecting tube 7. The end of the liquid collection section 83 is a flat end, and a flexible material (rubber, latex) is selected, even if it is released from the patient's body, it will not cause damage to the patient.
[0021] The mechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.
[0022] Components not described in detail herein are prior art.
