Description

Hook forceps

Technical Field

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

Background

In the otitis media operation, instruments such as ear hooks, crocodile forceps, strippers and the like are needed to separate, hook and clamp different tissues. The space in the ear is small, and the continuous operation of replacing instruments in the operation is very inconvenient, so that an instrument with the functions of separation, hooking and clamping is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a collude tweezers, can separate, hook in the ear, the different tissue of centre gripping.

Based on the above problem, the utility model provides a technical scheme is:

collude tweezers, including two elastic arms and two tweezers points, two elastic arm one end interconnect, the other end interval arrangement of two elastic arms makes two elastic arms are the V type, the tweezers point sets up the tip of elastic arm, the tweezers point with the elastic arm is the obtuse angle and connects, the medial surface of tweezers point is equipped with a plurality of centre gripping tooth portion.

In one embodiment, the elastic arm comprises a V-shaped forceps handle and a forceps arm arranged at the end of the forceps handle, and the width of the forceps arm is smaller than that of the forceps handle.

In one embodiment, a limiting block is arranged on the inner side face of at least one forceps handle.

In one embodiment, the width of the forceps arm gradually decreases from the forceps handle to the forceps tip.

In one embodiment, the width of the forceps tips is gradually reduced towards the outer end by the resilient arms.

In one embodiment, the width of the inner end part of the forceps tip is 0.3-0.8 mm.

In one embodiment, the outer end of the forceps tip is a circular arc surface.

In one embodiment, the diameter of the outer end part of the forceps tip is 0.05-0.08 mm.

In one embodiment, the included angle between the forceps tips and the elastic arms is 120-150 degrees.

In one embodiment, when the two forceps tips are close to fit, the inner side surfaces of the two forceps tips are engaged with each other.

Compared with the prior art, the utility model has the advantages that:

adopt the technical scheme of the utility model, the function that has stripper and ear hook when should colluding tweezers's tweezers point to be mediated has the function of separation when tweezers point is separately, should collude peeling off, separation and snatching that tweezers can be used to the interior tissue of ear, need not to change the apparatus, and convenient operation has improved the smoothness nature of operation.

Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

Referring to fig. 1-4, for the structural schematic diagram of the embodiment of the present invention, a pair of forceps is provided, including two elastic arms 1 and two forceps tips 2, one end of each of the two elastic arms 1 is connected to each other, the other end of each of the two elastic arms 1 is arranged at an interval to make the two elastic arms 1 in a V shape, the forceps tips 2 are disposed at the end of the elastic arms 1, wherein the forceps tips 2 are connected to the elastic arms 1 at an obtuse angle, and a plurality of clamping teeth 2-1 are disposed on the inner side of the forceps tips 2.

The clamping tooth part 2-1 can adopt various shapes, in this example, when the two forceps tips 2 are close to and attached, the inner side surfaces of the two forceps tips 2 are meshed with each other, and the clamping tooth part 2-1 is arranged to enable the forceps tips 1 to firmly clamp tissues in ears.

The included angle between the forceps tips 2 and the elastic arms 1 is 120-150 degrees, and preferably 135 degrees. The length of the forceps tip is 2.4-2.6 mm.

In this example, the elastic arm 1 comprises a V-shaped forceps handle 1-1 and a forceps arm 1-2 arranged at the end of the forceps handle 1-1, and the width of the forceps arm 1-2 is smaller than that of the forceps handle 1-1.

The width of the forceps arm 1-2 is gradually reduced from the forceps handle 1-1 to the forceps tip 2, and the outer side surface of the forceps arm 1-2 is a cambered surface. The inner side surface of one forceps handle 1-1 is provided with a limiting block 3 to control the clamping distance.

The outer side surface of the forceps handle 1-1 is provided with anti-slip lines 4 so as to facilitate operation in ear surgery and avoid slipping.

The width of the forceps tip 2 is gradually reduced from the forceps arms 1-2 to the outer end, and the width of the inner end of the forceps tip 2 is 0.3-0.8 mm, preferably 0.5 mm. The outer end part of the forceps tip 2 is arc-shaped, and the diameter of the outer end part is 0.05-0.08 mm, preferably 0.06 mm. The shape and structure of the forceps tip 2 are convenient for stripping and hooking tissues in the ear, and the forceps tip has the functions of a stripper and an ear hook.

The above examples are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable one skilled in the art to understand the contents of the present invention and to implement the present invention, which should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
