Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a concealed edge strip installation structure. Background Art
[0002] The breast lesion rotary cutting biopsy system is an active medical device. The main work of the breast lesion rotary cutting biopsy system is to match consumables (the cutter head) and perform pathological examinations on the obtained tissue samples. During clinical use, the phenomenon of replacing the cutter head will occur, and after replacing the cutter head, the driving handle and the cutter head need to be self-checked and confirmed to prevent affecting the surgical effect during use. The conventional breast lesion rotary cutting biopsy system determines whether the replacement has been made by means of negative pressure loss or screen clicking to replace the cutter head. This operation method will cause problems such as misjudgment or contamination of the doctor's gloves. Therefore, a rotary handle for placing a rotary cutting biopsy needle is designed to overcome the above problems. Summary of the Utility Model

The clamping handle is strip-shaped, with a concave and a convex clamping edge respectively arranged on both sides of the strip shape, and a surrounding edge is arranged below. A driving motor and a control board are installed at the bottom of the clamping handle within the surrounding edge. A through hole is opened at the bottom of the clamping handle, and the cable passes through the through hole and is connected to the control board at the bottom. The control board controls the driving motor to rotate to drive the biopsy needle to perform rotary cutting operations.
[0005] Preferably: The control board is installed on the side wall near the lower part within the surrounding edge and fixed by screws. A driving motor and a cable are installed on the control board. Among them, there are 2 driving motors, which are independently controlled respectively. One is connected to the rotary head on the biopsy needle to drive the rotation for cutting operations, and the other is connected to the lifting screw mechanism on the biopsy needle to drive the screw mechanism to lift the cutter head through rotation. A layer of surrounding edge is wrapped outside the driving motor.
[0006] Preferably: The 2 driving motors are respectively installed inside the motor housing and arranged side by side on the left and right. One side of their rotating shafts faces upward, and a cylindrical card slot is installed at the end of the rotating shaft. Multiple protruding limiting edges are arranged on the inner wall of the card slot to limit its movement through the limiting edges.
[0007] Preferably, the peripheral edge is fixed below the clamping handle by screws, enclosing the control board and the driving motor, and extending upward to the middle position of the clamping handle, forming an inwardly recessed clamping groove. And a limiting notch is provided on the outer side of the peripheral edge, and opposite clamping ports are provided above the notch. The rotary cutting knife can be inserted and fixed in the formed clamping groove to prevent movement during operation.

[0022] The control board 4 is installed on the side wall near the lower part inside the surrounding edge 6 and fixed by screws. A driving motor 3 and a cable 8 are installed on the control board 4. There are 2 driving motors 3, which are independently controlled respectively. One is connected to a rotary cutting head (not shown in the figure) on the biopsy needle to drive rotation for cutting operations, and the other is connected to a lifting screw mechanism (not shown in the figure) on the biopsy needle to drive the screw mechanism to lift the cutter head by rotation. A layer of surrounding edge 6 is wrapped outside the driving motor 3.
[0023] The 2 driving motors 3 are respectively installed inside the motor housing 22 and arranged on the left and right sides. One side of its rotating shaft 9 faces upward. A cylindrical card slot 10 is installed at the end of the rotating shaft 9. A plurality of protruding limiting edges 11 are provided on the inner wall of the card slot 10 to limit its movement through the limiting edges 11. The surrounding edge 6 is fixed below the clamping handle 2 by screws to wrap the control board 4 and the driving motor 3 inside.

When the infrared sensor 16 detects that the cutter head is misaligned, it sends an instruction to the control unit MCU20, and the control unit MCU20 sends a shutdown instruction to the drive motor 3 to stop rotating, preventing accidents.
[0028] In the present utility model, the infrared sensor is provided to detect whether the cutter head is inserted in place. When the infrared sensor detects that the cutter head is misaligned, it sends an instruction to the control unit MCU, and the control unit MCU sends a shutdown instruction to the drive motor to stop rotating, preventing accidents, thereby greatly improving the convenience and safety of the overall operation procedure.
[0029] The working principle of the infrared sensor in the present utility model is as follows:
[0030] An infrared emitter that cooperates with the infrared sensor is also provided on the rotary cutting head cutter head. When the position of the rotary cutting head cutter head is accurate after it is installed on the clamping handle, the infrared sensor can receive the infrared light emitted by the infrared emitter. When the position of the rotary cutting head cutter head installed on the clamping handle is inaccurate or the rotary cutting head is not installed, the infrared sensor does not receive the infrared light, then it sends an instruction to the control unit MCU, and the control unit MCU sends a shutdown instruction to the drive motor to stop rotating, preventing accidents, thereby ensuring the normal operation of the entire device.
