Fixing clamp and aligning device

Abstract

The invention relates to a fixing clamp (2) for an aligning device (1) for the fixing clamping of a bodily extremity, comprising a first clamp arm (14a) and a second clamp arm (14b), and comprising a frame device (12) having an attaching section (10) for attaching to an adjustment rod, as well as a first rotary joint (16a) and a second rotary joint (16b), at which the respective corresponding first clamp arm (14a) is rotatably attached about a first axis of rotation (D1) and the second clamp arm (14b) is rotatably connected about a second axis of rotation (D2), and comprising a locking mechanism which interlockingly locks the first clamp arm (14a) and / or the second clamp arm (14b) relative to the frame device (12) in at least one position, and which blocks a movement of the first or second clamp arm (14a, 14b) about the respective rotary joint (16a, 16b) in an open rotational direction. The invention also relates to an aligning device (1) comprising a fixing clamp (2) according to the invention, according to the associated claim.

Description

technical field [0001] The present invention relates to a fixation clamp / forceps for orienting devices, in particular for tibial resections, for fixation and clamping of a patient's body extremity, such as the tibia or tibia's ankle, malleolus, leg, ankle joint, so The fixing clamp / fixing pliers has a first clamp arm and a second clamp arm and has a frame device with a connecting section for connecting to the adjusting rod and a first adapter and a second adapter, corresponding to the first The clamp arm and the second clamp arm are rotatably coupled thereto about respective first and second axes of rotation. Furthermore, the invention relates to an orientation device / adjustment guide device for tibial resection guidance according to the preambles of the co-claims. Background technique [0002] Precise resection of the patient's bone, especially the tibia, is of great importance for the success of the procedure for implanting the joint prosthesis. In this case, the resecti...

AI Technical Summary

Problems solved by technology

However, the disadvantage is that for the fixation the bone is unnecessarily removed due to screwing into the calcaneus and the healthy bone tissue is damaged

The spring pretension results in a non-positive fixation, which however has the disadvantage that hematomas can be produced on the relevant body part of the patient due to the clamping force

[0011] However, the problem of the prior art is that the fixation on the patient's ankle bone is only force-locked or the clamp arms are pre-tensioned force-lockingly but not form-fittingly held in place (due to the resulting inherent elasticity of the clamp arms by This results in only insufficient positionability), or the screw has to be screwed into the (healthy) bone for fixation (this places an additional strain on the patient and also increases the risk of infection)

Furthermore, the clamping arms, which are elastically pretensioned by the clamping force, can produce hematomas on the patient's body parts

Furthermore, the fastening clamp according to the prior art does not cover all anatomy sizes, since the clamping force depends on the corresponding anatomy of the patient
