Same-plane and equal-angle swinging orthopaedic guide reset pliers

Abstract

The invention relates to a pair of same-plane and equal-angle swinging orthopaedic guide reset pliers, which belongs to the field of orthopaedic medical appliances. The pair of orthopaedic guide reset pliers comprises two plier arms and a guide sleeve (1), wherein a same-plane and equal-angle swinging mechanism which is used for realizing the equal-angle opening and closing of the pliers is arranged between the two plier arms. The pair of orthopaedic guide reset pliers is characterized in that the same-plane and equal-angle swinging mechanism is connected with a fixed limiting piece (8) which makes the plier arms swing on the same horizontal plane, the guide sleeve (1) is installed on the upper end of one plier arm through a parallel keeping mechanism, and measurement clamping mechanisms which is used for realizing the clamping of the plier arms are arranged on the lower ends of the two plier arms. According to the pair of same-plane and equal-angle swinging orthopaedic guide reset pliers, the parallel keeping mechanism and the same-plane and equal-angle swinging mechanism which makes the plier arms swing on the same swinging plane are arranged, so that the effects of accuracy in drilling and easiness in operation during fixing are achieved, the reset and guide of an internal fixture are simultaneously completed, the guide accuracy is increased, and the operation time is saved.

Description

technical field [0001] The utility model relates to an orthopedic guiding reduction forceps that swings at the same plane and at an equal angle, belonging to the field of orthopedic medical devices. Background technique [0002] In the treatment of humeral intercondylar fractures, humeral supracondylar fractures, humeral medial condyle fractures, and lateral condyle fractures, the ulnar nerve travels in the ulnar nerve groove on the posterior side of the medial epicondyle and the radial nerve is close to the bone surface at the crest of the lateral epicondyle of the humerus The reason for this is that the traditional approach in performing medial and lateral needle fixation is the conventional combined medial and lateral approach, fracture reduction under direct vision, blind needle puncture, and then fluoroscopy to confirm whether the entry and exit points of the drill bit and the length of the opposite side are ideal. When threading the needle, because a point cannot deter...

AI Technical Summary

Problems solved by technology

1. In this patent, the structure of the fixed plate that restricts the movement of the two pliers is also relatively complicated. The left and right guide grooves and the left and right sliders also have poor sliding during operation. Once the fixed plate and the slider are deformed or not smooth, they will Unsmooth sliding will lead to the failure of the implementation of the reset forceps, which will increase the difficulty of the operation and even cause the failure of the operation. This is a serious disadvantage

2. This patent needs to rely on another large fixed plate mechanism that restricts the movement of the left and right pliers body, and restricts the movement of the two pliers bodies and the two pliers tips in the same plane. During operation, the fixed plate will occupy a large surgical operation space on the inner side of the forceps arm , it may compress the soft tissue around the fracture, affect fracture reduction and operation

3. Although there are meshing clamping surface teeth between the fixed plate and the two pliers bodies, which can be automatically clamped after the reset is completed, but the clamping mechanism is not released, which makes unlocking difficult and inconvenient for the surgeon.
