[0027] The operating room needle finder provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0028] This embodiment specifically discloses an operating room needle finder, such as... Figure 1-3 As shown, the device includes a housing 1, a handle 2, a power supply, a controller, a metal detector 3, a first electric telescopic rod 4, an alarm 5, an electromagnet 6, and a first control button 7. The handle 2 is fixed to the side of the housing 1. In this embodiment, the housing 1 can be cylindrical, and the handle 2 is positioned perpendicular to the axis of the housing 1, making the operating room needle finder a handheld device that is small and portable. Medical staff can easily pick it up to find needles, improving needle finding efficiency. It can be used not only to find needles on the operating room floor but also when sutures fall onto a patient or bed, making it widely applicable.

[0029] Optionally, the handle 2 is covered with a protective cover 21, which has anti-slip texture to facilitate the handling and use by medical staff.

[0030] The power supply is fixed inside the outer casing 1. The power supply is electrically connected to the controller, metal detector 3, first electric telescopic rod 4, alarm 5 and electromagnet 6 respectively. The power supply is used to supply power to the controller, metal detector 3, first electric telescopic rod 4, alarm 5 and electromagnet 6. The power supply is connected to the above-mentioned electrical components through wires. A switch button 30 can also be embedded on the top surface of the outer casing 1 for controlling the on / off of the operating room needle finder.

[0031] Optionally, the power source is a dry cell battery or a rechargeable battery, and a battery compartment may be provided on the top, side or bottom of the housing 1, and the battery compartment is sealed by a sealing cover.

[0032] The controller is fixed inside the housing 1, which protects the controller. The controller is electrically connected to the metal detector 3, the first electric telescopic pole 4, the alarm 5, and the first control button 7. The metal detector 3 and the first control button 7 are connected to the controller's input interface, and the first electric telescopic pole 4 and the alarm 5 are connected to the controller's output interface. The first control button 7 controls the extension and retraction of the first electric telescopic pole 4. Through the control of the first control button 7 and the processing of the controller, the extension length of the first electric telescopic pole 4 can be precisely controlled. The controller can be a microprocessor.

[0033] After detecting the needle, the metal detector 3 transmits a signal to the controller, which then activates the alarm 5 to alert medical staff immediately upon detection of the needle, thus alleviating their anxiety.

[0034] Medical staff input control information by operating the first control button 7. The first control button 7 transmits the control information to the controller. After processing, the controller controls the first electric telescopic rod 4 to extend and retract, and to adjust the extension length accordingly.

[0035] The metal detector 3 and the first electric telescopic rod 4 are fixed to the bottom of the outer casing 1. The fixed end of the first electric telescopic rod 4 is fixedly connected to the outer casing 1, and the movable end of the first electric telescopic rod 4 is fixedly connected to the electromagnet 6. Preferably, the first electric telescopic rod 4 is fixed at the bottom center of the outer casing 1, and the extension line of the first electric telescopic rod 4 coincides with the central axis extension line of the outer casing 1. By controlling the extension length of the first electric telescopic rod 4, the distance of the electromagnet 6 relative to the outer casing 1 can be controlled, thereby allowing the electromagnet 6 to penetrate into narrow spaces or relatively deep cuts for needle searching.

[0036] Optionally, multiple metal detectors 3 can be provided to improve detection accuracy and speed up needle finding efficiency. The first electric telescopic rod 4 is fixed to the bottom center of the housing 1, and multiple metal detectors 3 are arranged around the first electric telescopic rod 4. Preferably, the multiple metal detectors 3 are evenly arranged around the first electric telescopic rod 4 to increase the detection area and improve detection efficiency.

[0037] When the operating room needle finder is activated, the metal detector 3 turns on to perform detection. Alternatively, a separate control button can be provided to control the switching on and off of the metal detector 3; the control button is embedded in the top of the housing 1.

[0038] The alarm 5 and the first control button 7 are embedded in the top of the housing 1. The alarm 5 is prominently positioned on the top of the housing 1 and can optionally be an alarm indicator light. The number of alarm indicator lights can be the same as the number of metal detectors 3, and they are configured in a one-to-one correspondence. When the metal detector 3 detects a suture needle, its corresponding alarm indicator light illuminates to sound an alarm. Medical personnel can then move the electromagnet 6 towards the metal detector 3 to retrieve the suture needle, improving needle retrieval efficiency. The first control button 7 is located on the top of the housing 1 for easy operation by medical personnel.

[0039] In some embodiments, such as Figure 2 and 3 As shown, a protective sleeve 8 is fitted around the first electric telescopic rod 4. The protective sleeve 8 is detachably connected to the movable end of the first electric telescopic rod 4, and the bottom end of the protective sleeve 8 is closed. The electromagnet 6 is fixed to the bottom end face of the protective sleeve 8. The protective sleeve 8 protects the first electric telescopic rod 4, especially when searching for needles inside the patient's incision, preventing the first electric telescopic rod 4 from coming into contact with the patient's body fluids and tissues, and preventing body fluids from adhering to the first electric telescopic rod 4 and affecting its performance. The protective sleeve 8 is detachably connected to the first electric telescopic rod 4. After the protective sleeve 8 comes into contact with human tissue or body fluids, it can be removed for cleaning and disinfection to ensure cleanliness and safety for subsequent use.

[0040] Optionally, such as Figure 4 As shown, a groove for placing the electromagnet 6 is provided on the bottom surface of the protective cylinder 8. The electromagnet 6 is embedded in the groove. The wire connected to the electromagnet 6 can pass through the bottom of the protective cylinder 8 and enter the outer casing 1 from inside the protective cylinder 8 to be electrically connected to the power supply and the controller respectively. The wire is set long enough not to affect the extension of the first electric telescopic rod 4. The bottom surface of the electromagnet 6 can be flush with the bottom surface of the protective cylinder 8 or protrude from the bottom surface of the protective cylinder 8.

[0041] To facilitate the connection between the protective cylinder 8 and the first electric telescopic rod 4, such as Figure 2 As shown, the movable end of the first electric telescopic rod 4 is fixed with an adapter block 9, and the protective cylinder 8 is threadedly connected to the adapter block 9. Figure 2 As shown, the adapter block 9 has an external thread, such as Figure 4 As shown, the inner wall of the protective cylinder 8 is provided with a thread that matches the external thread on the adapter block 9, and the thread on the protective cylinder 8 is close to the bottom end of the protective cylinder 8. The number of turns of the thread can be set to 1.5-5 turns to avoid excessive rotation of the protective cylinder 8 when disassembling it, which could affect the wires of the electromagnet 6.

[0042] Optionally, such as Figure 2 and 3As shown, a connecting block 11 is fixed to the bottom of the outer casing 1. The fixed end of the first electric telescopic rod 4 is fixedly connected to the connecting block 11. A receiving groove for accommodating the protective cylinder 8 is provided on the connecting block 11, and the groove wall is in contact with the protective cylinder 8. The depth of the receiving groove is greater than the extension stroke of the first electric telescopic rod 4, ensuring that even when the first electric telescopic rod 4 is extended to its maximum length, the upper edge of the protective cylinder 8 is still within the receiving groove, and the protective cylinder 8 can completely protect the first electric telescopic rod 4. The two side walls of the receiving groove are in contact with the inner and outer walls of the protective cylinder 8, preventing bodily fluids from entering the protective cylinder 8 when searching for the needle in the incision.

[0043] In some embodiments, such as Figure 2-4 As shown, the operating room needle finder also includes an incision dilation assembly 10. The incision dilation assembly 10 includes a dipping plate 101 and a second electric telescopic rod 102. Multiple dipping plates 101 are arranged around the protective cylinder 8. This application does not impose a special limitation on the number of dipping plates 101. Figure 3 As shown, in this embodiment, there are four deflecting pieces 101. Preferably, the deflecting pieces 101 are evenly arranged around the protective cylinder 8. The deflecting pieces 101 are connected to the protective cylinder 8 via second electric telescopic rods 102. Each deflecting piece 101 can be connected to one or more second electric telescopic rods 102. The number of second electric telescopic rods 102 corresponding to each deflecting piece 101 is adjusted according to the size of the deflecting piece 101. The fixed end of the second electric telescopic rod 102 is fixedly connected to the protective cylinder 8, and the movable end of the second electric telescopic rod 102 is fixedly connected to the deflecting piece 101. In this embodiment, the protective cylinder is cylindrical, and the second electric telescopic rod 102 is arranged radially along the protective cylinder. When the second electric telescopic rod 102 extends, the deflecting pieces 101 move away from the protective cylinder 8, at which time the cut opening assembly 10 gradually opens the cut. When the second electric telescopic rod 102 retracts, the deflecting pieces 101 move closer to the protective cylinder 8. The second electric telescopic rod 102 is electrically connected to both the power supply and the controller. The power supply provides power to the second electric telescopic rod 102. A second control button 20 is embedded in the top of the outer casing 1. The second control button 20 is electrically connected to the controller and is used to control the extension and retraction of the second electric telescopic rod 102. The second control button 20 is connected to the input interface of the controller, and the output interface of the controller is electrically connected to the second electric telescopic rod 102. Medical personnel operate the second control button 20 to input control signals, which are then transmitted to the controller. After processing, the controller precisely controls the extension and retraction of the second electric telescopic rod 102 and its extension length.

[0044] The second electric telescopic rod 102 is electrically connected to the power supply and controller via a wire. The wire extends into the inside of the protective cylinder 8 and is attached to the inner wall of the protective cylinder 8.

[0045] In this embodiment, the bottom end of the prying piece 101 is flush with or slightly lower than the bottom end of the protective tube 8, ensuring that the opening of the cut is not affected by the magnetic attraction of the electromagnet 6 to the suture needle.

[0046] The incision opening component 10 opens the patient's incision, which can reduce the contact between the sharp end of the suture needle and the patient's wound when removing the needle, thus reducing the patient's pain.

[0047] Optionally, such as Figure 2-4 As shown, the opening piece 101 includes a first part 1011 parallel to the outer wall of the protective cylinder 8 and a second part 1012 located below the first part 1011 and inclined towards the protective cylinder 8. That is, the lower part of the entire opening opening assembly 10 is conical, which facilitates the second part 1012 to first extend into the smaller opening and then gradually open the opening. The first part 1011 is parallel to the outer wall of the protective cylinder 8, which can ensure the stability of the opening and prevent human tissue from slipping down.

[0048] Optionally, the prying piece 101 can be a silicone sheet or a rubber sheet, made of a smooth and elastic material with a certain degree of hardness to avoid scratching human tissue and improve patient comfort.

[0049] Optionally, the bottom corners of the prying piece 101 are rounded to further avoid scratching human tissue and prevent secondary damage.

[0050] The operating room needle finder of this application is used as follows: When a metal suture needle is found to be missing, medical staff can hold the operating room needle finder, turn on the needle finder, and multiple metal detectors 3 are used to detect possible metal foreign objects in the surgical area to find the suture needle. After the suture needle is found, the alarm will sound. At the same time, the electromagnet 6 will attract the fallen suture needle. If a relatively narrow space is encountered, the first electric telescopic rod 4 can be extended to push out the electromagnet 6 and extend it into the narrow space to attract the suture needle. If a suture needle is found embedded in a patient's surgical incision, medical staff can insert the protective sleeve 8 along with the incision opening assembly 10 into the incision. When inserted, the incision opening assembly 10 can be in a closed state, slightly widening the incision. Alternatively, the second electric telescopic rod 102 can be extended to open the incision before insertion, depending on the specific situation. If the incision is deep, the first electric telescopic rod 4 can be extended, driving the protective sleeve 8 and the incision opening assembly 10 deeper into the incision. The suture needle is attracted by the electromagnet 6. When removing the suture needle, the second electric telescopic rod 102 can be extended to open the incision, allowing the needle to be removed. The incision opening assembly 10's ability to open the incision during needle removal reduces contact between the sharp end of the needle and the patient's wound, minimizing patient discomfort.

[0051] This utility model's operating room needle finder is small in size, and can be easily found even if a suture needle falls on the patient or the bed, making it widely applicable.
