Description

Curved pliers for animal experiments

technical field

The utility model relates to a medical experiment appliance, in particular to an arc-shaped pliers for animal experiments.

Background technique

At present, there is no special body wall spreader in the existing animal experiment operation. First, the animal body wall (such as the mouse body wall) is cut open, and then the four corners of the incision are clamped and pulled outward with curved forceps. After being pulled apart, the clamps can be fixed separately; or the metal wire can be bent into a hook shape, and a rubber strip is fixed behind it, and after the animal body wall is cut, the hook-shaped wires are used to hook the parts of the body wall respectively. Pull the corners outward, and secure the rubber strip behind the wire. The operation of the two methods is very troublesome. The bending forceps pulling needs to use multiple bending forceps and fix each bending forceps, while the wire pulling needs to bend the wire and fix the rubber strip before the experiment; It is also troublesome to clean the bending pliers and wire after the end. In addition, since the curved forceps are relatively troublesome to fix after clamping the animal body wall, another curved forceps is needed for fixation, so generally at most four curved forceps are used to pull the incision during the experiment, resulting in the inability to fully stretch the animal body wall , the ideal stretching effect cannot be achieved; and the use of wire pulling will damage the animal body wall, resulting in a longer recovery time for the animal after the experiment, which has a great impact on subsequent observations and subsequent experiments.

Contents of the invention

The purpose of the utility model is to provide a pliers for animal experiments with simple structure and easy operation.

In order to achieve the above object, the utility model can take the following technical solutions:

The arc-shaped pliers for animal experiments described in the utility model includes a pliers body hinged by left and right pliers bodies, and the left pliers body is composed of a first pliers head, a first pliers arm and a first finger. The right pliers body is composed of a second pliers head, a second pliers arm and a second finger ring; inside the first pliers arm is provided with locking teeth extending toward the second pliers arm A locking bar, a locking buckle matching the locking bar is arranged on the inner side of the second pliers arm; inwardly curved arcs are fixed horizontally at the front ends of the first and second pliers heads shaped clamping arm, the outer end of the arc-shaped clamping arm is screwed with a detachable end cap, and a body wall clamping piece is slidably arranged on the arc-shaped clamping arm; the body wall clamping piece includes Slidingly fit the cylindrical slider on the arc-shaped clamping arm and the body wall clip fixed on the bottom of the cylindrical slider vertically downwards, set screws on the cylindrical slider, so The outer peripheral surface of the handle portion at the outer end of the positioning screw is a rough surface.

The front ends of the first and second pliers are bent downward to form a bent portion.

The utility model has the advantages of simple structure, only needs a supporting pliers to complete the operation, and does not need to be manually processed in advance, easy to operate, and very convenient to clean and disinfect before and after the experiment; adapt to the body wall according to the shape of the animal incision The number of clamping parts, so that the body wall clamping parts evenly clamp the edge of the animal incision, pull in multiple directions when stretching, multi-point clamping makes the force more uniform, the incision stretching effect is good, and the arc clamp The holding arm can be adapted to a variety of incision shapes, such as "cross", "u", "n", etc., to meet different experimental requirements and have a wide range of applications; the body wall clamp is used for clamping, and there is no damage to the animal body wall , which is conducive to the healing of the postoperative incision and improves the speed of subsequent experiments.

Detailed ways

As shown in Figures 1 and 2, the arc-shaped supporting jaw pliers for animal experiments described in the utility model comprises a left pliers body composed of a first pliers head 1.1, a first pliers arm 1.2 and a first finger ring 1.3, and is composed of a first pliers head 1.1, a first pliers arm 1.2 and a first finger ring 1.3 Two pliers heads 2.1, the second pliers arm 2.2 and the second finger ring 2.3 form the right pliers body, and the left and right pliers bodies are hinged to form the supporting jaw pliers body; for convenience, the opening angles of the left and right pliers bodies are fixed. A locking bar 3 with locking teeth extending to the second pliers arm 2.2 is provided on the inner side of the first pliers arm 1.2, and a locking buckle 4 matching the locking bar 3 is arranged on the inner side of the second pliers arm 2.2, for Make the locking angle as large as possible, and the locking bar 3 is an arc-shaped structure that bends toward the front end of the brace body; the front ends of the first pliers head 1.1 and the second pliers head 2.1 are respectively horizontally fixed with an inward-curved arc Clamping arm 5, the outer end of the arc-shaped clamping arm 5 is screwed with a detachable end cap 6, when the body of the pliers is closed, the end faces of the two detachable end caps 6 fit together, so that the two arc-shaped clamping The arms 5 are surrounded by a circular or elliptical structure with a good supporting effect; a body wall clamping piece is slidably arranged on the arc clamping arm 5, and the body wall clamping piece includes a sliding sleeve on the arc clamping arm 5. The cylindrical slider 7 and the body wall clamp 8 fixed to the bottom of the cylindrical slider 7 and vertically downward, for reducing the damage to the animal body wall when the body wall clamp 8 clamps as much as possible, the lower end of the body wall clamp 8 The clamping part is two clamping planes that fit together, rough surfaces can also be set on the two clamping planes of the clamping part to improve the clamping force; the body wall can be easily installed or disassembled by unscrewing the detachable end cap 6 Clamping parts, the number of body wall clamping parts depends on the size and shape of the incision; set screws 9 are pierced on the cylindrical slider 7, and when the body wall clamping parts slide in place, tighten the set screws 9, The inner end of the set screw 9 is pressed against the arc-shaped clamping arm 5, thereby fixing the position of the body wall clamp; for the convenience of screwing the set screw 9, the outer peripheral surface of the handle 10 at the outer end of the set screw 9 is a rough surface. In addition, in order to keep the spreader body away from the animal body and avoid the influence of the spreader body on the experimental operation, as shown in Figure 3, the front ends of the first clamp head 1.1 and the second clamp head 2.1 are bent downward to form a curved part, and the arc clamp The holding arm 5 is connected to the lower end of the curved part of the first pincer head 1.1 and the second pincer head 2.1, so that the position of holding the pliers is as far away as possible from the position of clamping the animal body wall, and at the same time, the body of the pliers can be fixed. More convenient.

When in use, first unscrew the detachable end cap 6 according to the size and shape of the incision and set the number of suitable body wall clamps, and then evenly clamp the body wall clip 8 at the lower part of the body wall clamp At the edge of the incision on the animal body wall, then open the left and right pliers, so that the two arc-shaped clamping arms 5 are opened to a suitable position (as shown in Figure 4); finally, through the locking bar 3 and the locking buckle 4 The fastening of the incision makes the opening angle fixed, and the opening operation of the incision is completed; after that, the subsequent experimental operation can be carried out.
