Problems solved by technology
[0003] However, the existing orthopedic surgery reduction forceps are large in size and difficult to meet the needs of minimally invasive, and manual clamping and reduction are required. The fracture end is held by tools such as bone forceps, and the assistant assists in traction to correct the fracture displacement. There is a lot of manpower; there is a need for a fracture reduction forceps that is easy to operate and stable in clamping, and is specially used for minimally invasive surgery

Embodiment 1
[0019] Example 1: Figure 1-Figure 3 A fracture reduction forceps for minimally invasive surgery is shown. The fracture reduction forceps for minimally invasive surgery is mainly composed of a frame body 1, a fixing clip 2, a lifting mechanism 3 and a reduction forceps 4. The fixing clip 2 is arranged on the At the bottom end of the frame body 1, the lifting mechanism 3 is arranged on the frame body 1, and the reset clamp 4 is arranged on the lifting mechanism 3; the fixing clip 2 is mainly composed of: a fixing plate 22, a movable The plate 21 and the fastening bolts 23 are combined, the fixed plate 22 is arranged at the bottom of the frame body 1, and the movable plate 21 is sleeved on the frame body 1 and connected by the fastening bolts 23; The lifting mechanism 3 is mainly composed of a slider 31, a screw 32 and a drive motor 33. One end of the screw 32 is slidably connected to the frame body 1 through the slider 31, and the other end of the screw 32 is connected to the f...

The invention discloses fracture reduction forceps for minimally invasive surgery, the fracture reduction forceps for minimally invasive surgery are mainly formed by combining a frame body, a fixing clamp, a lifting mechanism and reduction forceps, the fixing clamp is arranged at the bottom end of the frame body, the lifting mechanism is arranged on the frame body, and the reduction forceps are arranged on the lifting mechanism; the bone reposition forceps are simple in structure, convenient to operate, safe, effective, small in wound, capable of effectively protecting soft tissue, capable of achieving minimally invasive accurate reposition by means of fluoroscopy and suitable for reposition of long tubular bones of all parts, clamping of the forceps portions is firm and labor-saving, clamping force does not need to be exerted by holding the forceps for a long time, the reposition forceps can be partially installed on a lifting mechanism when needed, and the operation is convenient. The reduction forceps can stably move and reset at a constant speed, surrounding soft tissue injury is reduced, and the reduction forceps are safer and more reliable.
Description
technical field [0001] The invention relates to the field of orthopedic surgical appliances, in particular to a fracture reduction forceps for minimally invasive surgery. Background technique [0002] The basic principles of fracture treatment are fracture reduction, fixation and rehabilitation. Modern minimally invasive orthopedics advocates that fracture patients have less iatrogenic injury, faster healing and fewer complications. With minimal trauma and docile, stable reduction and internal fixation is a good start for fracture healing, so that patients can exercise as soon as possible, recover as soon as possible, and return to their original life and work. [0003] However, the existing reduction forceps for orthopaedic surgery are relatively bulky and difficult to achieve minimally invasive requirements. They also need to be manually clamped and reduced. The fracture ends are held by tools such as bone forceps, and assistants assist in traction to correct the fracture ...
