Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to a calcaneal shaping and reduction forceps. Background Art

[0002] After a fracture, it is generally necessary to perform bone reduction treatment. In the prior art, bone holding forceps are often used to reduce the broken bones and fix them with steel plates, screws, etc. Commonly used reduction forceps are mainly composed of two X-shaped forceps arms hinged together, with the front end as a clamp and the rear end as a handle. Calcaneus fracture is the most common tarsal fracture and is prone to occur in middle-aged men. Since calcaneal fracture can seriously damage the talocalcaneal joint, cause adhesion and stiffness, as well as bone spur formation and calcaneal malformation, it can leave pain and motor dysfunction in the affected foot. Therefore, in addition to clarifying the fracture type, functional treatment should be emphasized during treatment, that is, early movement of the affected foot and gradual weight-bearing walking to achieve satisfactory functional recovery, and it is not appropriate to overemphasize the anatomical reduction and strong fixation of the fracture fragments. At present, open reduction and plate internal fixation of calcaneal fractures are prone to complications such as skin necrosis, plate exposure, and osteomyelitis, leading to treatment failure.

The number of the first tooth grooves is multiple so that first claw teeth are formed between adjacent first tooth grooves.

[0006] As an improvement, the bottom surface of the first tooth groove is an arc-shaped groove bottom that is concave inwards.

[0007] As an improvement, the distance between the first tooth groove and the two ends of the first clamping jaw is smaller than the distance between the second tooth groove and the two ends of the second clamping jaw.

[0008] As an improvement, the right clamp handle includes an upper clamp handle connected to the first clamp jaw and a lower clamp handle connected to the right handle. The connection between the end of the upper clamp handle and the upper end of the lower clamp handle is an arc transition connection so that the angle between the upper clamp handle and the lower clamp handle is an obtuse angle.

[0009] As an improvement, the left clamp handle includes a connecting handle connected to the second clamp jaw and a left main handle connected to the left handle, and the connecting handle is used to be connected to the left clamp handle mounting groove.

[0010] As an improvement, the right spring plate includes a main spring plate connected to the right clamp handle and a movable plate connected to the roller, the main spring plate is an arc-shaped plate, and the movable plate is a straight plate. An angle is provided between the movable plate and the arc-shaped plate so that when the roller moves to the top of the long slide, the straight plate is parallel to the long slide and can be accommodated in the long slide.

[0011] As an improvement, the length from the top of the right clamp handle to the mother-and-child pin is greater than the length from the top of the left clamp handle to the mother-and-child pin.

[0012] As an improvement, the bottom of the left and right pliers handles are also provided with left and right pin handles connected to the left and right handles, and the left and right handles are provided with pins fixedly connected to the left and right pin handles.

[0013] After adopting the above structure, the present invention has the following advantages: the present invention has a simple structure and is easy to use. Through the first clamp and the second clamp that are adapted to the shape of the human calcaneus, surgical treatment can be performed in a short time when the swelling of the calcaneal fracture has not subsided. By using the calcaneal shaping and reduction forceps of the present invention, the first clamp and the second clamp can clamp the calcaneus to restore the length, width and inversion angle of the calcaneus, which can effectively treat calcaneal fractures at an early stage and reduce the complications of traditional open surgery.
