As shown in fig. 1 and fig. 2, the medical forceps according to the embodiment of the first aspect of the present invention includes a forceps main body 100, a swinging piece 200 and a reading unit 300, the forceps main body 100 is of an existing structure and includes a first forceps piece 110 and a second forceps piece 120, a root of the first forceps piece 110 is connected to a root of the second forceps piece 120, and a head of the first forceps piece 110 is freely opened to a certain distance from a head of the second forceps piece 120. For convenience of description below, the side of the first forceps piece 110 opposite to the second forceps piece 120 is taken as an inner side, and the outer side of the first forceps piece 110 and the outer side of the second forceps piece 120 are arranged oppositely. The first forceps piece 110 and the second forceps piece 120 can be made of spring steel, so that the first forceps piece 110 and the second forceps piece 120 can be elastically opened and closed, and a medical worker can clamp the forceps pieces by pressing the two forceps pieces.

In addition, the outer side of the first forceps piece 110 is welded with a pin 111, the middle of the swinging piece 200 is provided with a pin hole matched with the pin 111, so that the swinging piece 200 can be rotatably connected to the outer side of the first forceps piece 110, and at the moment, the rotating plane of the swinging piece 200 and the clamping plane of the forceps main body 100 form an included angle.

In order to measure the relevant parameters of the wound, the swing sheet 200 is provided with a depth gauge 210 along the length direction thereof, and the medical staff can directly use the depth gauge 210 on the swing sheet 200 to measure the depth of the wound. The reading unit 300 is respectively connected to the root of the first forceps piece 110 and the root of the swinging piece 200, and since the swinging piece 200 can be unfolded relative to the first forceps piece 110, when a medical worker needs to measure the length or the width of a wound, the swinging piece 200 can be rotated, so that the head of the swinging piece 200 and the head of the first forceps piece 110 respectively correspond to two ends of the wound, and at this time, the reading unit 300 is used for reading the size of an opening between the swinging piece 200 and the first forceps piece 110, thereby completing the measurement of the length or the width of the wound. Compared with the prior art, the utility model discloses but the relevant parameter of direct measurement wound when handling the wound to medical personnel's use, and because swing piece 200 with the expansion of first tweezers piece 110 can not receive the influence that tweezers main part 100 elasticity opened and shut, consequently the utility model discloses a measured data is more accurate.

It is understood that the swinging piece 200 can be rotatably connected to the outer side of the second forceps piece 120, but is not limited to the above embodiment, and when the swinging piece 200 is rotatably connected to the outer side of the second forceps piece 120, the reading units 300 are respectively connected to the root of the second forceps piece 120 and the root of the swinging piece 200.

Specifically, the reading unit 300 comprises an arc dial 310, a connecting rod 320 and a pointer 330, the arc dial 310 is fixedly connected to the root of the first forceps piece 110, the arc dial 310 is provided with curved scales, the pointer 330 is rotated along the scale direction of the arc dial 310, and two ends of the connecting rod 320 are respectively hinged to the root of the swinging piece 200 and the middle of the pointer 330. When the swinging piece 200 rotates relative to the first forceps piece 110, the swinging piece 200 drives the pointer 330 to rotate through the link 320, and the position of the pointer 330 on the arc scale 310 changes accordingly, so that the purpose of reading is achieved. It should be noted that, although the reading unit 300 is essentially used for measuring the opening included angle between the swinging piece 200 and the first forceps piece 110, the value of the opening included angle can be converted into the value of the opening size according to the rule of similar triangle, so as to facilitate the reading of the medical staff.

In other embodiments, the reading unit 300 includes a linear dial fixedly connected to the root of the first tweezer blade 110, a link 320 and a pointer 330, the linear dial is provided with linear scales, the pointer 330 slides along the scale direction of the linear dial, the root of the swinging blade 200 is provided with a kidney-shaped hole, one end of the link 320 is fixedly connected to the middle of the pointer 330, and the other end of the link 320 is slidably hinged to the kidney-shaped hole. When the swinging piece 200 rotates relative to the first forceps piece 110, the swinging piece 200 drives the pointer 330 to slide linearly through the connecting rod 320, and the position of the pointer 330 on the linear scale is changed accordingly, so that the purpose of reading is achieved. It should be noted that, although the reading unit 300 is essentially used for measuring the opening included angle between the swinging piece 200 and the first forceps piece 110, the value of the opening included angle can be converted into the value of the opening size according to the rule of similar triangle, so as to facilitate the reading of the medical staff.

In other embodiments, the reading unit 300 comprises a tape measure, which may be a tape measure, the tape measure is fixedly connected to the root of the first forceps blade 110, the tape measure is provided with a retractable tape, and the head end of the tape is hinged to the root of the swinging blade 200. When the swinging piece 200 rotates relative to the first forceps piece 110, the swinging piece 200 can pull out a tape with a corresponding length, so as to achieve the purpose of reading. It should be noted that, since the real length of the tape only reflects the distance between the root of the swinging piece 200 and the root of the first forceps piece 110, according to the rule of similar triangles, the scale on the tape needs to be converted to display the size of the opening between the swinging piece 200 and the first forceps piece 110.

It can be understood that, the present invention does not limit the specific structure of the reading unit 300, as long as the reading unit 300 can read the opening size between the swinging piece 200 and the first forceps piece 110, no matter what structure the reading unit 300 has, all belong to the protection scope of the present invention.

As shown in fig. 3 and 4, the size of the swinging piece 200 is not larger than that of the first forceps piece 110, so that when the swinging piece 200 is folded in the first forceps piece 110, the swinging piece 200 does not exceed the first forceps piece 110, so as to prevent the swinging piece 200 from causing additional damage when the forceps body is used for clamping.

In some embodiments of the present invention, in order to avoid interference, the swinging piece 200 is reserved with a clearance avoiding position 220 avoiding the reading unit 300, so that the swinging piece 200 can be smoothly collected, and the clearance avoiding position 220 can also be used as a finger position, so as to facilitate the expansion of the swinging piece 200.

In some embodiments of the present invention, the head of the second forceps piece 120 is bent inward, so that the head of the second forceps piece 120 is parallel to the head of the first forceps piece 110, so that the forceps body can be clamped.

In some embodiments of the present invention, since the swinging piece 200 is folded in the first forceps piece 110 when the forceps body is used for holding, the outer side of the swinging piece 200 and the outer side of the second forceps piece 120 are respectively holding surfaces for medical personnel. In order to improve the holding hand feeling of the medical forceps, an anti-slip strip (not shown in the drawings) is arranged on the outer side surface of the second forceps piece 120, and the depth gauge 210 on the swinging piece 200 is also arranged to be of an anti-slip strip structure, so that the friction coefficient of the holding surface is increased, and the anti-slip function is achieved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
