Improved skull traction frame for neurosurgery

Abstract

The invention provides the improved skull traction frame for neurosurgery. The improved skull traction frame comprises a connecting frame, a laser baffle, an adjusting device, a sickbed fixing frame,a tension displayer, a traction rope, a fixing hook, a laser limiting device, a traction device, a power supply and a buzzer, wherein the connecting frame is clamped in the middle of the sickbed fixing frame. Due to the arrangement of the tension displayer, the metering is accurate, and the traction force borne by the skull of a patient can be directly known. The magnitude of the traction force can be adjusted according to the actual situation by referring to the tension display. Due to the arrangement of the adjusting device, the complex program in the prior art is simplified. The traction force on the skull of a patient can be adjusted through a nut and a screw rod. The laser limiting device and the buzzer are arranged, whether the traction force of the patient is in a straight line or not is determined through laser reflection, and the skull of the patient can be effectively prevented from being injured due to unbalanced traction force borne by the skull.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an improved neurosurgery skull traction frame. Background technique [0002] The cranial distractor is an instrument used for preoperative reduction and stabilization in the treatment of cervical trauma and cervical deformity, but the traditional cranial distractor has the following defects: the retractor has one traction buckle, which is set on the top of the traction bow or the symmetrical bow body Therefore, it only relies on a single point to pull and apply force, which does not have a clamping effect, and there is a problem that the traction rope is easy to deviate, and the deflection of the traction rope will directly affect the fixed pins that have been symmetrically positioned and perforated on the cranial parietal bone. This uneven force is the main reason for retractor slippage, and the direct consequence of retractor slippage is to induce complications such as ...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an improved skull distraction frame for neurosurgery, to solve the problem that the traction force is not visible in the existing combined skull distractor with a positioning frame, and the size of the force on the patient's skull The budget is inaccurate, and it is more troublesome to solve the problem of uneven traction force of the skull tractor. It also needs to occupy a person to observe whether the traction force is uniform, and the adjustment of the traction force is also troublesome. The problem of complex structure
