Non-shielding fracture reduction forceps

Abstract

The invention discloses non-shielding fracture reduction forceps. The non-shielding fracture reduction forceps comprise a right forceps piece (1) and a left forceps piece (2) hinged to the right forceps piece (2) through a pin (3). A left clamping arm is formed at the front end of the right forceps piece (1), and a right handle is formed at the rear end of the right forceps piece (1). A right clamping arm is formed at the front end of the left forceps piece (2), and a left handle is formed at the rear end of the left forceps piece (2). The non-shielding fracture reduction forceps are characterized in that the left clamping arm is divided into a left bent arm (5) and a left clamping section (10), the left bent arm (5) is bent continuously in the horizontal direction to form an arc shape and is bent continuously by an alpha angle in the perpendicular direction; the right clamping arm is divided into a right bent arm (4) and a right clamping section (11), the right bent arm (4) is bent continuously in the horizontal direction to form an arc shape and is bent continuously by an alpha angle in the perpendicular direction; an operation cavity (12) is formed between the left clamping arm and the right clamping arm; the inner side of the left clamping section (10) and the inner side of the right clamping section (11) are each one third of a circular arc face, a clamping cavity (13) is formed between the left clamping section (10) and the right clamping section (11), and the longitudinal section of the clamping cavity (13) is two thirds of the circular arc shape.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to orthopedic surgery, and is particularly suitable for fracture reduction and fixation tools for tubular bones of extremities. Background technique [0002] In fracture surgery, fracture reduction is the first step in the treatment, and it is also the most important step in the whole treatment. How to fix the restored fractured bones under stable conditions often requires the use of fracture reduction forceps. However, all kinds of reduction forceps we have been using, as well as all documents including patents that have not yet been converted into products, all have the obstruction of the fracture site or the operation space after the reduction forceps themselves are fixed. Although some instruments can avoid occlusion to a certain extent, there is a phenomenon that the bone slips toward the root when pressurized, and the meaning of using the reduction forceps is lost. Although s...
