Description

A kind of medical tweezers with large clamping force

technical field

The utility model belongs to the technical field of surgical instruments, devices or methods, and in particular relates to a medical tweezers with a large clamping force.

Background technique

Tweezers are the most commonly used surgical medical instruments. They are used to hold objects or tissues. The tweezers of existing tweezers mostly thicken from front to back. The centerlines of the tweezers head and tweezers are on the same straight line. Two tweezers heads of the same size grip the object through the grip force of the hand, the grip force is limited, and the grip force will be further weakened when the hand is loose.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the above-mentioned shortcomings of the existing tweezers, and provide a medical tweezers with a large clamping force, which has a reasonable design, a simple structure, low cost, a large clamping force, and the clamped object is not easy to fall.

The technical solution adopted to solve the above-mentioned technical problems is: comprising elastic tweezers tails, the two ends of the elastic tweezers tails are respectively provided with an upper tweezers rod and a lower tweezers rod, and a thrust force is provided between the upper tweezers rod and the lower tweezers rod. spring, the tail end of the upper tweezers rod is provided with an upper tweezers head, the upper tweezers head is provided with a through hole, the tail end of the lower tweezers rod is provided with a lower tweezers head, and the lower tweezers head A pressing block is arranged on the top, and the position and quantity of the pressing block are adapted to the through holes provided on the upper tweezers head.

Both the upper tweezers head and the lower tweezers head of the utility model are of circular structure.

The upper tweezers head of the utility model has the same structure as the lower tweezers head.

The upper tweezers head and the upper tweezers rod of the utility model are in the same plane, and the lower tweezers head and the lower tweezers rod are in the same plane.

The compacting block of the utility model is a circular truncated compacting block.

The diameter of the bottom circle of the frustum-shaped pressing block of the utility model is smaller than the diameter of the through hole.

The lower tweezers head of the utility model is evenly arranged with 1 to 6 pressing blocks.

Because the utility model adopts that the upper tweezers head and the lower tweezers head are provided with corresponding pressing blocks and through holes respectively, when objects such as gauze are clamped, the pressing blocks act on the gauze to make the gauze sag in the through holes, Not easy to fall, there is a thrust spring between the upper tweezers rod and the lower tweezers rod, when the operator releases his hand, because the pressing block is trapped in the through hole when clamping the object, the upper tweezers rod and the lower tweezers rod are not easy to separate, The upper tweezers rod and the lower tweezers rod are separated under the action of the thrust spring. The utility model has the advantages of simple structure, low cost, large clamping force, and the clamped object is not easy to drop, and is easy to use, and can be extended and applied to the technical field of medical devices.

In the figure: 1. elastic tweezers tail; 2. upper tweezers rod; 3. thrust spring; 4. upper tweezers head; 5. lower tweezers rod; 6. lower tweezers head; 7. pressing block.

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment, but the utility model is not limited to these embodiments.

Example 1

In Fig. 1, 2, the utility model is a kind of large-grip medical tweezers, including elastic tweezers tail 1, and the two ends of elastic tweezers tail 1 are respectively connected as a whole to be provided with upper tweezers rod 2, lower tweezers rod 5, upper tweezers rod 2, upper tweezers rod A thrust spring 3 is installed between the rod 2 and the lower tweezers rod 5. When the operator releases his hand, the upper tweezers rod 2 and the lower tweezers rod 5 are not easy to separate because the pressing block 7 is trapped in the through hole when clamping the object. The upper tweezers rod 2 and the lower tweezers rod 5 are separated under the action of the thrust spring 3, and the upper tweezers head 4 is installed on the tail end of the upper tweezers rod 2. In this embodiment, the upper tweezers head 4 is a circular structure and the upper tweezers head 4 and The upper tweezers bar 2 is arranged in the same horizontal plane, the upper tweezers head 4 is provided with a through hole, and the tail end of the lower tweezers bar 5 is equipped with a lower tweezers head 6. In this embodiment, the lower tweezers head 6 is a circular structure and the lower tweezers head 6 The head 6 and the lower tweezers rod 5 are arranged in the same plane, and the lower tweezers head 6 is equipped with a pressing block 7. In this embodiment, the position and quantity of the pressing blocks 7 are adapted to the through holes provided on the upper tweezers head 4, Further, the pressing block 7 is a frustum-shaped pressing block, and the diameter of the bottom surface of the frustum-shaped pressing block is smaller than the diameter of the through hole provided on the upper tweezers head 4. In order to make the clamping more stable, in this embodiment Three pressing blocks 7 are evenly distributed on the lower tweezers head 6 , and the upper tweezers head 4 and the lower tweezers head 6 in this embodiment have the same structure.
