Description

Technical Field

[0001] The present utility model application relates to the technical field of separating forceps, and specifically relates to a long straight separating forceps convenient for operation in a narrow space. Background Art

[0002] The forceps for basic surgery refer to medical devices for surgical operations such as ordinary hemostatic forceps, tissue forceps, hard alloy inlaid needle holders, ordinary needle holders, etc. There are usually two types of separating forceps: composed of two pieces connected in the middle, with the head being the forceps beak; or composed of a head, a rod part and a handle, and the head being a pair of blades with forceps beaks, generally made of stainless steel material, used for separating tissues. Common ones include separating forceps, peeling forceps, abdominal cavity separating forceps, laryngeal separating forceps, etc.

[0003] Currently, the connecting shaft of the separating forceps is usually close to the forceps head. With this design, when the separating forceps are opened, the handle part usually needs to be separated by a large distance. When the separating forceps are in a narrow space, there is usually not enough space to separate the handle part, which makes it very inconvenient to use the separating forceps in a narrow space. Summary of the Invention

[0004] In order to solve the problem that when the separating forceps are opened, the handle part usually needs to be separated by a large distance, and when the separating forceps are in a narrow space, there is usually not enough space to separate the handle part, which makes it very inconvenient to use the separating forceps in a narrow space, the present utility model provides a long straight separating forceps convenient for operation in a narrow space to solve the above problems.

[0005] To achieve the above object, the present utility model provides the following technical solutions:

[0006] A long straight separating forceps convenient for operation in a narrow space, including a separating forceps head main body, a first separating forceps body and a second separating forceps body. The first separating forceps body is arranged inside the second separating forceps body. One side of both the first separating forceps body and the second separating forceps body is provided with a separating forceps head main body. A fixing block is fixed at one end of the second separating forceps body close to the separating forceps head main body. Two first forceps head extension rods are symmetrically and slidably connected inside the fixing block above and below. One end of each first forceps head extension rod is fixedly connected to the separating forceps head main body. A number of limiting grooves are formed inside the first forceps head extension rod. A second forceps head extension rod is slidably connected inside the first separating forceps body. One end of the second forceps head extension rod is fixedly connected to the other separating forceps head main body. A fixing screw hole is formed on the side of the second forceps head extension rod away from the first forceps head extension rod. The first forceps head extension rod and the fixing screw hole are fixed to the second separating forceps body and the first separating forceps body through a fixing structure.

[0007] Further, a first separating forceps handle is fixed to one end of the first separating forceps body away from the separating forceps head body. A first separating forceps extension rod is slidably connected inside the first separating forceps handle. A second separating forceps handle is fixed to one end of the second separating forceps body away from the separating forceps head body. A second separating forceps extension rod is slidably connected inside the second separating forceps handle. The first separating forceps extension rod and the second separating forceps extension rod are fixed inside the first separating forceps handle and the second separating forceps handle by fixing screws.

[0008] Further, the fixing structure includes a fixing block. A limiting rod is rotatably connected inside the fixing block. One end of the limiting rod away from the fixing block is engaged with a limiting groove. The fixing screw hole is fixed inside the first separating forceps body by a fixing screw.

[0009] Further, the bottom surface of the limiting groove is in contact with the top surface and the bottom surface of the second separating forceps body. The top surface and the bottom surface of the second separating forceps body are in contact with the first jaw extension rod.

[0010] Further, the first separating forceps extension rod and the second separating forceps extension rod have the same length. The shapes of the first separating forceps extension rod and the second separating forceps extension rod are both "convex" shaped. The shapes of the inner sliding grooves of the first separating forceps handle and the second separating forceps handle are both matched with the shapes of the first separating forceps extension rod and the second separating forceps extension rod.

[0011] Further, the number of the limiting grooves and the fixing screw holes opened is the same, and the positions where the limiting grooves and the fixing screw holes are opened correspond to each other.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, by respectively fixing a first jaw extension rod and a second jaw extension rod on one side of the two separating forceps head bodies close to the first separating forceps body, and fixing the two separating forceps head bodies to the first separating forceps body and the second separating forceps body respectively through the limiting rod and the fixing screw, the distance between the two separating forceps head bodies and the connecting shaft is increased, solving the problem that when the separating forceps are separated, the handle part usually needs to be separated by a large distance. When the separating forceps are in a narrow space, there is usually not enough space to separate the handle part, which makes it very inconvenient to use the separating forceps in a narrow space.

[0014] 2. In the present utility model, by respectively fixing a first separating forceps handle and a second separating forceps handle at one end of the first separating forceps body and the second separating forceps body away from the separating forceps head main body, and sliding a first separating forceps extension rod and a second separating forceps extension rod inside the first separating forceps handle and the second separating forceps handle, the length of the handle part can be conveniently adjusted, so that the length of the handle part matches the length of the forceps head part, thereby enhancing the adjustment space of the separating forceps.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the application purpose, features, and advantages of the present application more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the embodiments described below are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] Refer to Figure 1 、Figure 2 , Figure 3 and Figure 4 , a long straight separating forceps convenient for operation in a narrow space, comprising a separating forceps head body 1, a first separating forceps body 2 and a second separating forceps body 3. The first separating forceps body 2 is arranged inside the second separating forceps body 3. One side of the first separating forceps body 2 and the second separating forceps body 3 is provided with the separating forceps head body 1. A fixing block 4 is fixed at one end of the second separating forceps body 3 close to the separating forceps head body 1. Two first jaw extension rods 5 are symmetrically and slidably connected inside the fixing block 4 above and below. One end of each first jaw extension rod 5 is fixedly connected to the separating forceps head body 1. A plurality of limiting grooves 13 are formed inside the first jaw extension rod 5. A second jaw extension rod 11 is slidably connected inside the first separating forceps body 2. One end of the second jaw extension rod 11 is fixedly connected to the other separating forceps head body 1. A fixing screw hole 14 is formed on one side of the second jaw extension rod 11 far from the first jaw extension rod 5. The first jaw extension rod 5 and the fixing screw hole 14 are fixed on the second separating forceps body 3 and the first separating forceps body 2 through a fixing structure, so that the distance between the separating forceps head body 1 and the connecting shaft can be adjusted.

[0023] Specifically, the fixing structure includes the fixing block 4. A limiting rod 6 is rotatably connected inside the fixing block 4. One end of the limiting rod 6 far from the fixing block 4 is engaged with the limiting groove 13. The fixing screw hole 14 is fixed inside the first separating forceps body 2 through a fixing screw 12. The bottom surface of the limiting groove 13 is attached to the top surface and the bottom surface of the second separating forceps body 3. The top surface and the bottom surface of the second separating forceps body 3 are attached to the first jaw extension rod 5. The number of the limiting grooves 13 and the fixing screw holes 14 formed is the same, and the positions where the limiting grooves 13 and the fixing screw holes 14 are formed correspond to each other, which is convenient for controlling the positions between the two separating forceps head bodies 1.

[0024] As an optimized scheme, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a first separating forceps handle 7 is fixed at one end of the first separating forceps body 2 far from the separating forceps head body 1. A first separating forceps extension rod 8 is slidably connected inside the first separating forceps handle 7. A second separating forceps handle 9 is fixed at one end of the second separating forceps body 3 far from the separating forceps head body 1. A second separating forceps extension rod 10 is slidably connected inside the second separating forceps handle 9. The first separating forceps extension rod 8 and the second separating forceps extension rod 10 are fixed inside the first separating forceps handle 7 and the second separating forceps handle 9 through a fixing screw 12, so that the first separating forceps extension rod 8 and the second separating forceps extension rod 10 cooperate with the separating forceps head body 1 to control the length.

[0025] Specifically, the first separating pliers extension rod 8 and the second separating pliers extension rod 10 have the same length, and the shapes of the first separating pliers extension rod 8 and the second separating pliers extension rod 10 are both "convex" shaped. The shapes of the internal slide grooves of the first separating pliers handle 7 and the second separating pliers handle 9 are matched with the shapes of the first separating pliers extension rod 8 and the second separating pliers extension rod 10, which facilitates the first separating pliers extension rod 8 and the second separating pliers extension rod 10 to be fixed inside the first separating pliers handle 7 and the second separating pliers handle 9.

[0026] Working principle: According to the required length of the separation forceps in the surgical scenario, the limit rod 6 is toggled to release the limit of the first forceps head extension rod 5 by the limit rod 6, and at the same time, the fixing screw 12 on one side of the first separation forceps body 2 is turned to release the limit of the second forceps head extension rod 11 by the fixing screw 12. At this time, the staff can pull the separation forceps head body 1 outward, so that the distance between the separation forceps head body 1 and the connecting shaft becomes farther. When it is pulled to a suitable position, the limit rod 6 is toggled to make the limit rod 6 engage into the limit groove 13, so that the limit rod 6 can separate the separation forceps head body 1. The fixing screw 12 on the first separating pliers body 2 is limited and fixed, and at the same time, the fixing screw 12 is rotated so that the fixing screw 12 is engaged with the fixing screw hole 14, so that the other separating pliers head body 1 is fixed by the fixing screw 12. When the adjustment length of the first pliers head extension rod 5 and the second pliers head extension rod 11 is insufficient, the fixing screw 12 on the first separating pliers handle 7 and the second separating pliers handle 9 is opened, so that the first separating pliers extension rod 8 and the second separating pliers extension rod 10 slide inside the first separating pliers handle 7 and the second separating pliers handle 9, so that the separating pliers handle part can be conveniently adjusted with the pliers head.
