Description

A magnetic bar for cleaning magnetic foreign bodies after surgery

technical field

The invention relates to a medical magnetic bar, in particular to a magnetic bar for cleaning magnetic foreign objects after an operation site.

Background technique

Medical magnetic rods are commonly used instruments in surgical operations. They are used for surgical openings of patients. Since surgical instruments are mostly metal products, metal fragments on some instruments will inevitably be peeled off after the operation, and even screws and nuts will fall off. If larger metal fittings such as these are placed at the surgical site, these substances left in the patient's body are likely to cause secondary disease.

At present, the commonly used medical magnetic rod is generally a rod-shaped structure with a magnetic suction head. Due to the different sensitivity of the human body to the magnetic field, an excessively strong magnetic field will destroy the original biological magnetic field in the human body after a certain period of time, and induce a micro-current. It will change the permeability of the cell membrane, seriously destroy the activity of some enzymes, and the human body will also experience dizziness and vomiting. In addition, for some special groups, such as fracture patients, metal fixation may be applied to the affected part. Needle, too strong magnetic field for too long can easily loosen the fixed needle, which is not conducive to the recovery of the bone. Another example is a patient with a cardiac pacemaker implanted in the body, too strong magnetic field for too long may interfere with the positioning of the pacemaker . Therefore, the magnetism of conventional magnetic rods should not be too strong. When in use, only some relatively light metal fragments can usually be absorbed. For relatively large metal accessories such as screws and nuts, the current magnetic rods can only play a "sensing" function. It is difficult to suck it out directly, and more often, auxiliary tools such as tweezers are needed to clamp it out after finding the position; in addition, due to the poor regularity of the muscle tissue at the surgical site after the operation, it will be accompanied by human tissues such as fascia and membrane. , which increases the difficulty of absorbing relatively large metal accessories such as screws and nuts, and also makes the movement of the magnetic rod in the surgical site more inconvenient.

Therefore, the existing medical magnetic rods have the problems that it is not easy to take out relatively large metal fittings such as screws and nuts that fall off the surgical site at one time, the movement in the surgical site is inconvenient, and it is easy to cause physical damage to special groups.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a magnetic bar for cleaning magnetic foreign bodies after surgery. It has the advantages of being able to take out relatively large metal accessories such as screws and nuts falling off the surgical site at one time, flexibly moving on the surgical site, and causing less physical damage to special groups.

The technical solution of the present invention is as follows: a magnetic rod for cleaning magnetic foreign objects after an operation site, comprising a rod body, one end of the rod body is connected with a handle, and the other end of the rod body is connected with a magnetic suction head, and the magnetic suction head is a columnar structure as a whole, Its outer end is a rounded blunt head, and the outer wall of the magnetic suction head is connected with a stripping head extending in the direction of the central axis of the magnetic suction head; the stripping head includes a plane part connected with the outer wall of the magnetic suction head, and one end of the plane part is connected with a directional magnetic head. The magnetic arc surface is bent at the central axis of the suction head; the magnetic suction head is provided with an electromagnet, the handle is provided with a power supply, and the handle is provided with a switch outside, and the electromagnet is connected with the power supply through a cable running through the inside of the rod body.

In the aforementioned magnetic rod for cleaning magnetic foreign bodies after surgery, the magnetic arc surface is a sheet-like structure, and the center of the sheet-shaped magnetic arc surface is hollowed out to form a ring.

In the aforesaid magnetic rod for cleaning magnetic foreign objects after operation, the width of the magnetic arc surface gradually narrows from one end connected to the flat surface to the other end.

In the aforementioned magnetic rod for cleaning magnetic foreign bodies after surgery, the magnetic field strength of the electromagnet is 2-5 times the magnetic field strength of the magnetic arc face.

In the aforesaid magnetic rod for cleaning magnetic foreign bodies after surgery, the rod body and the handle are threadedly connected.

In the aforesaid magnetic rod for cleaning magnetic foreign bodies after surgery, the rod body and the magnetic suction head are threadedly connected.

Compared with the prior art, the present invention has two parts that can generate magnetism. Among them, the magnetic suction head has a built-in electromagnet, which is energized to generate magnetism after pressing the switch, and the peeling head connected to the outer wall of the magnetic suction head includes a curved magnetic arc. The face, the magnetic arc surface is a permanent magnet, and there is no need to press the switch on the handle during normal use, that is, the electromagnetic part does not work, and some relatively light metal fragments can be absorbed and taken out only by the magnetic arc surface. At the same time, it can also sense some relatively large metal accessories such as screws and nuts. Although the large metal accessories cannot be sucked out only by the magnetic arc surface, after sensing these accessories, you can move the magnetic suction head to the position of the accessories, press the handle After the electromagnet attracts the relatively large metal fittings, the magnetic bar is immediately removed. After using this method, the relatively large metal fittings such as screws and nuts that fall off the surgical site can be taken out at one time. After being electrified, a large magnetic field will be generated, but taking out the magnetic rod immediately makes the strong magnetic field stay in the body for a short time, causing less physical damage even to such special populations with cardiac pacemakers implanted in the body.

The peeling head of the present invention is arranged in a structure in which a plane part and a magnetic arc surface are connected. The plane part makes the peeling head easy to be integrally connected with the magnetic suction head. In addition to attracting metal fragments, the magnetic arc surface can also open the surgical site, which is convenient for the magnetic rod. In the movement of the surgical site, further, the magnetic arc surface is a sheet-like structure, and the middle of the sheet-shaped magnetic arc surface is hollowed out to form a ring body. Fascia, membranes and other sundries are easy to move, and when the surgical site moves, the hollow structure produces less resistance, which is also beneficial to movement; further, the magnetic arc surface is connected to the flat part from one end to the other. The tapered width allows the invention to be inserted and aligned quickly even with narrow surgical site openings.

In addition, the magnetic field strength of the electromagnet is 2-5 times of the magnetic field strength of the magnetic arc face, which ensures that the electromagnet has enough time to be taken out from the surgical site after being energized; They are all threaded connections, and the three can be recycled and reused, and can be replaced individually after damage, reducing the cost of surgical instruments.

To sum up, the present invention has the advantages that relatively large metal fittings such as screws and nuts that fall off the surgical site can be taken out at one time, can be flexibly moved on the surgical site, and cause less physical damage to special populations.
