Description

Technical Field

[0001] The invention relates to the technical field of bone marrow puncture, and in particular to a handle-type electric drive device for bone marrow puncture. Background Art

[0002] The handle-type electric drive device for bone marrow puncture is an innovation and breakthrough based on the traditional manual bone marrow puncture technology. Traditional bone marrow puncture relies on the doctor's wrist strength and experience. The operation is time-consuming and laborious, and it is difficult to control the depth of insertion, which increases the patient's pain and the risk of operational errors. With the advancement of medical technology, electric drive devices have come into being. Their design cleverly combines electric power assistance with handle operation, greatly simplifying the bone marrow puncture process. The device controls the electric drive system through the handle to stably and quickly push the puncture needle into the bone marrow cavity, which not only improves the accuracy and efficiency of the puncture, but also significantly reduces the patient's discomfort and the doctor's operating burden. It is another important achievement in the humanized and precise development of modern medical technology.

[0003] For example, the Chinese utility model (CN212755731 U) discloses a bone marrow puncture and extraction device for hematology, which solves the following problems: the above patents all adopt manual operation, which not only has low accuracy, but also requires manual labor for puncture, and the uneven puncture force applied to the patient can easily cause pain to the patient.

[0004] The device includes a shell, a handle and a fixed column. The handle is arranged at the bottom of the shell, and the fixed seat is arranged at the top of the shell. A battery and a control mainboard are arranged inside the handle, and the battery is electrically connected to the control mainboard. A bottom cover is arranged at the bottom of the handle, and a charging interface and a control switch are arranged at the bottom of the bottom cover. A hand grip groove is arranged on the right side of the handle, and a motor control gear switch and a water pump control gear switch are arranged on the handle above the hand grip groove. An operation button and an operation display screen are arranged on the left side of the front outer surface of the shell. A slide groove is arranged inside the shell, and a sampling barrel is arranged in the slide groove. A water pump is arranged in the sampling barrel, a needle is arranged on the right side of the sampling barrel, a connecting rod is arranged on the left side of the sampling barrel, and a forward and reverse motor is arranged on the left side of the fixed column. A screw nut is sleeved on the screw rod, and the bottom of the screw nut is fixed to the connecting rod. It not only has high precision but also greatly reduces the pain of patients.

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: the device has no speed regulation function, which results in the device only being able to move forward at a fixed speed during the puncture process. The doctor cannot adjust the puncture speed in real time according to the patient's specific situation. If the device still maintains high-speed advancement when encountering hard bones, it will cause excessive puncture force, increasing the patient's pain and discomfort. For this reason, we designed a handle-type electric drive device for bone marrow puncture to provide another technical solution to the above technical problems. Summary of the invention

[0064] The use process of a handle-type electric drive device for bone marrow puncture provided by the present invention is as follows: when in use, the doctor installs the puncture needle through the installation shaft 4, and the user presses the switch 2 to energize the second motor 26, thereby energizing the second motor 26 to rotate, and the output end of the second motor 26 drives the rotating column 10 to rotate, and the rotation of the rotating column 10 drives the first gear 11 to rotate. Since one side of the first gear 11 is meshed and connected to the fourth gear 17, the rotation of the fourth gear 17 drives the rotating rod 20 to rotate, and the rotation of the rotating rod 20 drives the first bevel gear 22 to rotate. One side of the first bevel gear 22 is meshed and connected to the second bevel gear 23, so that the rotation of the first bevel gear 22 drives the second bevel gear 23 to rotate, thereby driving The mounting shaft 4 and the puncture needle rotate, and the doctor aims the puncture needle at the patient for puncture treatment. When speed regulation treatment is needed, the user energizes the first motor 6 to rotate, and the output end of the first motor 6 drives the screw 7 to rotate. Since a screw sleeve 8 is threadedly connected to one side of the screw 7, the rotation of the screw 7 drives the screw sleeve 8 to move, thereby pushing the rotating column 10 to move, thereby causing the third gear 13 to disengage from the meshing connection with the fourth gear 17. When the sixth gear 19 slides and contacts the limiting column 15, the third gear 13 disengages from the meshing connection with the fourth gear 17, and the second gear 12 resumes the meshing connection with the fifth gear 18, and at the same time, the first gear 11 is not meshed with the sixth gear 19. When it is necessary to continue speed regulation, the user Continue to press the switch 2 to adjust the rotation speed of the first motor 6, so that the slider 9 overcomes the elastic force of the first spring 16 and continues to move forward, thereby driving the sixth gear 19 to engage with the first gear 11, thereby disengaging the fifth gear 18 from the meshing connection with the second gear 12, and the third gear 13 also disengages from the meshing connection with the fourth gear 17, so that the speed of the device is adjusted. When puncturing the patient, the user pulls the handle 35, and then pulls the slide column 33 and the third spring 36, so that the friction rubber 34 can slide inside the first slide rail sleeve 30, and at the same time, the friction rubber 34 is disengaged from the fitting connection with the second slide rail sleeve 31, and the user pulls the first slide rail sleeve 30 and the second slide rail sleeve 31. The user releases the handle 35. Under the elastic force of the third spring 36, the friction rubber 34 resumes the fitting connection with the first slide rail sleeve 30, so that the second slide rail sleeve 31 and the first slide rail sleeve 30 can remain in an extended state, so that the first slide rail sleeve 30 can fit the patient's skin at a ninety-degree state, and at the same time, the first slide rail sleeve 30 can provide support for the rotation of the mounting shaft 4, so that the mounting shaft 4 does not swing left and right during puncture, thereby preventing the rescue medicine from leaking out after puncture. In summary, the present invention can significantly improve the convenience and safety of operation, optimize time management, improve patient comfort, and improve the maintenance efficiency of equipment, bringing a better user experience to doctors and patients.
