Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The present embodiment provides a bone forceps for reduction, as shown in fig. 1, 2 and 3, the bone forceps for reduction comprises a first forceps rod 1, a second forceps rod 2, a rotating shaft 4, a plate holding rod 11, a plate holding foot 12, a bone holding rod 21 and a bone holding member 22; the first clamp rod 1 and the second clamp rod 2 are hinged through a rotating shaft 4 and are formed into an X shape; the two plate holding rods 11 are connected to the front end of the first clamp rod 1 in a V-shaped manner, the coplanar of the two axes of the two plate holding rods 11 is parallel to the axial direction of the rotating shaft 4, one side of each plate holding rod 11, which is close to the second clamp rod 2, is connected with two plate clamping feet 12 at intervals, and a clamping area 13 for clamping a fixing plate is formed between the plate clamping feet 12 of each plate holding rod 11; the two bone clamping rods 21 are connected to the front end of the second forceps rod 2 in a V-shaped manner, the coplanar of the two axes of the two bone clamping rods 21 is parallel to the axial direction of the rotating shaft 4, the front end of each bone clamping rod 21 is connected with one bone clamping piece 22, and each bone clamping piece 22 is crescent-shaped and has an opening facing the clamping area 13.

Fig. 1 is a schematic view of a first forceps rod 1 and a second forceps rod 2 in a separated state, which can also be said to be a schematic view of a reduction forceps in a separated state; fig. 2 is a schematic view showing a state where the first forceps lever 1 and the second forceps lever 2 are connected by the rotation shaft 4, and may be said to be a schematic view showing a state where the reduction forceps is assembled. When the reduction bone-holding forceps of the present embodiment are used, the first forceps rod 1 and the second forceps rod 2 can be hinged by the rotating shaft 4 to adjust the distance between the clamping feet 12 and the bone clamping member 22. Firstly, the first clamping bar 1 and the second clamping bar 2 are rotated through the rotating shaft 4 to adjust the distance between the plate clamping foot 12 and the bone clamping piece 22 so as to simultaneously accommodate the bone to be reset and the fixing plate; then, the bamboo tube-shaped bone to be restored is accommodated in the two bone clamping pieces 22, and the fixing plate is limited in the clamping area 13 by the two sets of plate clamping feet 12; furthermore, the bone to be restored and the fixing plate are firmly fixed between the bone clamping member 22 and the clamping area 13 by adjusting the angle between the first clamping bar 1 and the second clamping bar 2, and then the bone to be restored and the fixing plate are fixed by steel nails and the like. When the bone holding forceps for resetting fixes the fixed plate and the broken bone through the embodiment, only one hand is needed to complete the operation, the number of operators and the operation time are saved, and the fixed plates such as the steel plate can be clamped and fixed more firmly through the two sets of relatively arranged plate clamping feet 12, so that the positioning in the operation process is more accurate, the auxiliary damage can be effectively avoided, and the treatment of patients is facilitated.

Example 2

According to the bone forceps for reduction in embodiment 1, as shown in fig. 1, 2 and 3, the distance between the centers of the two clamping areas 13 (referring to the geometric centers) or the distance between the midpoints of the two bone clamping pieces 22 (referring to the midpoints between the two ends) is 6cm, or can be 4-8 cm; the distance between the two plate clamping feet 12 of each plate holding rod 11 and the distance between the two ends of each bone clamping member 22 are the same and are 2.5cm, 4cm or 4.5 cm. As described above, the distance between the two plate holding legs 12 and the distance between the two ends of each bone holding member 22 are 2.5cm, which is suitable for the treatment of the fracture of the diaphysis of the ulna, clavicle, or fibula, 4.0cm for the treatment of the fracture of the diaphysis of the tibia or humerus, and 4.5cm for the treatment of the fracture of the diaphysis of the femur.

Example 3

According to the reduction forceps of embodiment 1, as shown in fig. 1, 2 and 3, the finger ring 5 for inserting a finger is connected to the rear ends of the first forceps rod 1 and the second forceps rod 2. The rear ends of the first clamp rod 1 and the second clamp rod 2 are oppositely provided with limiting pieces 6. When the reduction bone-holding forceps of the embodiment is used, the angle between the first forceps rod 1 and the second forceps rod 2 can be conveniently adjusted by hooking the fingers of an operator, such as a thumb and a middle finger, on the two finger rings 5 respectively, so that the distance between the plate clamping foot 12 and the bone clamping piece 22 can be more conveniently adjusted; the first clamping bar 1 and the second clamping bar 2 can rotate around the rotating shaft 4 more stably through the limiting sheet 6, so that dislocation is avoided.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
