Description

Technical Field

[0001] This invention relates to the field of microsurgical technology, specifically to a microscopic electromagnetic needle holder. Background Technology

[0002] Microsurgery, a highly refined medical technique, is widely used in various clinical fields. It utilizes microscopes and precision surgical instruments, allowing surgeons to perform precise operations within an extremely small surgical field. This surgical approach is particularly suitable for the repair and reconstruction of delicate structures such as blood vessels, nerves, and lymphatic vessels, greatly improving the success rate of surgery and patient recovery. A commonly used tool in microsurgery is the needle holder.

[0003] Currently, the needle holders used in microsurgery have limited functionality. When the surgical area is magnified under a microscope, the surgical field of view becomes smaller. This makes it difficult to locate the needle during suturing if the field of view is slightly changed or the needle position is adjusted. Furthermore, when the needle is in tissue, the microsurgical needle holder can easily puncture or clamp the tissue, causing tissue damage. Therefore, its practical effectiveness is not ideal. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a microscopic electromagnetic needle holder, solving related problems associated with needle holders used in microsurgery. When the surgical area is magnified under a microscope, the surgical field of view becomes smaller. This makes it difficult to locate the needle during suturing operations if the field of view or needle position is slightly changed. Furthermore, when the needle is in tissue, the microscopic needle holder can easily puncture or clamp the tissue, causing tissue damage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a microscopic electromagnetic needle holder, comprising an upper arm of the needle holder and a lower arm of the needle holder disposed at its bottom end, wherein the needle holding ends of the upper arm and the lower arm of the needle holder are respectively integrally formed with a first needle holder front end and a second needle holder front end, and the first needle holder front end and the second needle holder front end are hingedly connected by a pin, and a connecting mechanism is installed on the upper arm of the needle holder;

[0006] The connection mechanism includes a power connector fixed to the outer wall of the upper arm of the needle holder. A solenoid is wound around the outer periphery of the upper arm of the needle holder. An electric wire is wrapped inside the solenoid, and the two ends of the electric wire are connected to the power connector.

[0007] Preferably, a limiting post is fixed to the outer side of the front end face of the upper arm of the needle holder.

[0008] Preferably, the tail end of the upper arm of the needle holder is integrally formed with a first connecting edge.

[0009] Preferably, the lower arm of the needle holder is integrally formed with a second connecting edge at its tail end.

[0010] Preferably, the wire and the power connector form a closed circuit.

[0011] Beneficial effects

[0012] This invention provides a microscopic electromagnetic needle holder, which has the following beneficial effects:

[0013] A power connector can be fabricated on the upper arm of the needle holder. A solenoid is wound around the upper arm of the needle holder, and the two ends of the wire inside the solenoid are connected to the positive and negative terminals of the power connector. When the doctor uses this device, the power connector can be connected to an external low-voltage power source, allowing current to flow through the wire. As the current passes through the solenoid wire, a uniform magnetic field is created within the solenoid, magnetizing the upper arm of the needle holder. During suturing, when the surgical area is magnified under a microscope, the surgical field of view becomes smaller. Due to the magnetic effect of the upper arm of the needle holder, the needle will automatically adhere to it, preventing it from being lost. Even if the needle is outside the field of view, the magnetic field strength can be increased by increasing the current to attract the needle to the needle holder, allowing for quick location of the needle. Once the needle is attracted to the micro-electromagnetic needle holder and removed from the tissue, the position and angle of the needle can be adjusted for suturing. This reduces the risk of tissue damage due to puncture or clamping, resulting in better practical performance. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 and 2The present invention provides a technical solution: a microscopic electromagnetic needle holder, including an upper arm 1 and a lower arm 2 disposed at its bottom. The needle holding ends of the upper arm 1 and the lower arm 2 are respectively integrally formed with a first needle holder front end 3 and a second needle holder front end 4, and the first needle holder front end 3 and the second needle holder front end 4 are hingedly connected by a pin 5. A connecting mechanism is installed on the upper arm 1.

[0020] The connecting mechanism includes a power connector 6 fixedly connected to the outer wall of the top end of the upper arm 1 of the needle holder. A solenoid 7 is wound around the outer periphery of the upper arm 1 of the needle holder. An electric wire 8 is wrapped inside the solenoid 7. The two ends of the electric wire 8 are connected to the power connector 6.

[0021] The upper arm 1 of the needle holder can be made of silicon steel or permalloy, which allows for faster magnetization when energized. It also features high toughness, a strong electromagnetic field when energized, rapid demagnetization upon power failure, resistance to corrosion, and is harmless to the human body. Direct current (DC) is recommended over alternating current (AC) for a more stable magnetic field and to prevent noise. The solenoid 7 is made of insulating material for added safety. After the solenoid 7 is wound around the upper arm 1 of the needle holder, its end can be bent back to near the initial winding point. The two ends of the wire 8 are then connected to the positive and negative terminals of the power connector 6. The ends can be secured with adhesive to prevent the solenoid 7 from loosening. The power connector 6 can be designed similarly to those used for laparoscopic dissecting forceps, prioritizing its ease of use during surgery.

[0022] In this embodiment, a limiting post 9 is fixedly attached to the outer side of the front end face of the upper arm 1 of the needle holder.

[0023] In this embodiment, the tail end of the upper arm 1 of the needle holder is integrally formed with a first connecting edge 10.

[0024] In this embodiment, the lower arm 2 of the needle holder is further configured to have a second connecting edge 11 integrally formed at its tail end.

[0025] In this embodiment, the wire 8 is configured to form a closed circuit with the power connector 6.

[0026] In this way, the current only passes through wire 8, and no current passes through the area where the micro electromagnetic needle holder comes into contact with the surgeon and the patient, so it will not cause damage to human tissue.

[0027] It is worth noting that all standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The models of electrical structures and equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. Furthermore, the circuit connections adopt conventional connection methods in the prior art, and the control, current detection, position feedback, predicted voltage synchronization, and parameter adjustment of the electrical equipment are all existing technologies and will not be described in detail here. All content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0028] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0029] Example: When this device is needed, a power connector 6 can be machined at the upper arm 1 of the needle holder. A solenoid 7 is wound around the upper arm 1 of the needle holder, and the two ends of the wire 8 inside the solenoid 7 are connected to the positive and negative terminals of the power connector 6. When the doctor uses this device, the power connector 6 can be connected to an external low-voltage power source, allowing the wire 8 to be energized. When the current passes through the solenoid wire 8, a uniform magnetic field is created within the solenoid 7, thus magnetizing the upper arm 1 of the needle holder. During the suturing operation, when the surgical area is magnified under a microscope, the surgical field of view becomes smaller. Due to the magnetic effect of the upper arm 1 of the needle holder, the needle will automatically adhere to the upper arm 1 of the needle holder, making it less likely to be lost. Even if the needle is outside the field of view, the current can be increased to increase the magnetic field strength, attracting the needle to the needle holder for quick location. Once the needle is attracted to the micro-electromagnetic needle holder and removed from the tissue, the position of the clamped needle can be adjusted for suturing, reducing the risk of puncturing or clamping the tissue and causing tissue damage. Therefore, the actual usage effect is better.
