Technical Field

The utility model relates to the technical field of medical instruments, in particular to medical tweezers.

Background

The most common medical forceps are stainless steel straight forceps with pointed heads, and when the forceps are used for clamping instruments, the contact area between the forceps heads and the instruments is small, so that the forceps are only suitable for clamping instruments with small volume. When the tip tweezers are used for clamping instruments or objects with large volumes, especially round and conical instruments, the tip tweezers are easy to slide off, so that the instruments fall back into the box. If the device falls on a table or the ground, the device can be damaged and can be polluted, and the device needs to be disinfected and sterilized again. Therefore, the workload of nurses is increased, the clinical use is influenced, and the waiting time and the treatment time of patients are prolonged. Therefore, in order to conveniently grip articles with specific shapes (such as round pipes and conical pipes), the structure of the existing tweezers needs to be improved.

In view of the above problems in the prior art, there is a need in the art for a forceps that can easily grip round or conical instruments with less effort.

Detailed Description

The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.

It should be noted that all expressions of "first", "second", "third", and the like in the embodiments of the present invention are used for distinguishing a plurality of entities with the same name but different names or different parameters, and it should be understood that "first", "second", "third", and the like are only for convenience of description and should not be construed as limiting the embodiments of the present invention, and the descriptions of the following embodiments are omitted.

In view of the above, the embodiment of the present invention provides an embodiment of medical forceps. Fig. 1 is a schematic view of the medical forceps of this embodiment, and fig. 2 is a side schematic view of the medical forceps of fig. 1. As shown in figures 1 and 2, the medical forceps mainly comprise two forceps handles 1 arranged in a V shape and two forceps heads 2 respectively arranged at the front ends of the forceps handles 1, the tail ends of the two forceps handles 1 are configured into arc-shaped connecting sections 3 for connecting the two forceps handles together, and preferably, the two forceps handles 1 are of an integrally formed structure, so that the external force applied by a user when the forceps are used is smaller.

In order to make the medical forceps adapt to a round or conical instrument, the forceps handle 1 and the forceps head 2 are combined together in a movable connection mode. Specifically, as shown in fig. 3 and 4, fig. 3 shows the connection condition of the front end of the medical forceps, fig. 4 shows the structure of the forceps head of the medical forceps, a connecting block 7 is fixedly arranged at the front end of each forceps handle 1, a circular hole (not shown) is formed in the connecting block 7 and is perpendicular to the bottom of the connecting block 7, an orifice of the circular hole is located at the bottom of the connecting block 7, an upward connecting rod 8 is arranged at the top of each forceps head 2, the connecting rod 8 is inserted into the circular hole, a threaded hole (not shown) penetrating through the circular hole is further formed in the side of the connecting block 7, and a screwing screw 9 (shown in fig. 5) is screwed into the threaded hole. The two forceps heads 2 are arc-shaped, and the arc openings are opposite to each other.

In order to ensure that the contact area between the forceps head 2 and an instrument is larger, the forceps are clamped more stably, and the instrument is prevented from falling off to damage the instrument, the arc-shaped forceps head 2 is semi-arc-shaped, the arc-shaped diameter of the arc-shaped forceps head 2 is 2-2.2cm, and the width of the forceps head 2 is at least larger than that of the forceps handle 1.

Preferably, as shown in figure 2, each forceps handle 1 of the medical forceps is provided with a transverse anti-slip line 5 on the outer pinching surface. The lines of the transverse anti-slip lines 5 are in waveform and linear staggered arrangement, and the design increases the friction force between the transverse anti-slip lines 5 and the hands, so that the medical forceps have better anti-slip capability, and the medical forceps are prevented from slipping when being held by medical staff.

Preferably, as shown in fig. 3, an anti-slip pad 4 is fixedly arranged on the concave arc surface on the inner side of each forceps head 2, the size of the anti-slip pad 4 is matched with that of the arc forceps head 2, the thickness of the anti-slip pad 4 can be 1-3mm, the anti-slip pad 4 has elasticity, and can be made of an elastic material such as rubber or silica gel, for example, so that when an external force is applied to the forceps to clamp an object, the anti-slip pad 4 can be greatly deformed, and after the external force is removed, the deformation can be recovered, thereby preventing the clamped object from being damaged due to improper force application. Further, the contact surface of the object on the inner side of the non-slip mat 4 is provided with the transverse grains 6, and the transverse grains 6 increase the non-slip capacity of the non-slip mat 4, so that the clamped instrument is not easy to slip.

As shown in fig. 4, the side portion of the connecting rod 8 is provided with an annular connecting rod groove 81 which is matched with the screwing screw 9, and after the connecting rod 8 is inserted into the circular hole, the annular connecting rod groove 81 is opposite to the threaded hole, so that the screwing screw 9 can be clamped in the annular connecting rod groove 81.

It will be appreciated by those skilled in the art that the above numerical limitations should not limit the scope of the present invention, which is merely a preferred embodiment of the present invention. Those skilled in the art can make modifications as needed, as long as they can solve the technical problems described above.

In conclusion, the medical forceps provided by the utility model can clamp round or conical instruments, and has the advantages of small volume, low cost, firmness, durability, strong practicability and high safety. The whole tweezers are made of stainless steel materials, cleaning, disinfecting and sterilizing are convenient, the head of the tweezers is shaped into an arc shape with the left side and the right side symmetrical, the head of the arc tweezers can be fixed after rotating to an expected angle, and therefore an operator can conveniently and labor-saving clamp instruments or articles which are slightly large in size and circular or conical in shape. The tweezers are provided with anti-slip designs at the stress positions (the outer side of the tweezers handle is pinched to the holding surface and the inner side of the tweezers head is provided with the concave arc surface), so that the friction force can be increased, and the instruments taken by the tweezers are not easy to slip.

When the forceps is used, the arc forceps heads are rotated to a proper angle according to the shape of the clamped instrument, the screwing screw is unscrewed, the connecting rods on the arc forceps heads can rotate in the connecting blocks at the moment, the rotation of the arc forceps heads is further realized, and when the arc forceps heads rotate to a required angle, the screwing screw is screwed, and the arc forceps heads are fixed. Then, the user holds the anti-slip thread position of the forceps handle, the circular or conical instrument is clamped through the arc-shaped forceps head, the clamping is more labor-saving and stable due to the fact that the arc-shaped forceps head is matched with the circular or conical instrument in shape, the circular or conical instrument cannot easily fall off in the clamping process, and damage to the forceps head is avoided.

Although the utility model has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
