Universal mechanical instrument support with screwing and locking function

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a universal mechanical instrument support with a screwing and locking function. The support comprises a first cannula and a second cannula, and a first sleeve is fixed to the first cannula; a second sleeve is fixed to the second cannula; cylindrical head screws are arranged in the first sleeve and the second sleeve in a penetrating mode, and screwing handles are connected to the cylindrical head screws; second threaded holes are formed in the cylindrical head screws, and locating screws are connected to the second threaded holes; second shaft rods are arranged in the second cannula in a penetrating mode, first wedge-shaped surfaces are arranged on the second shaft rods, second wedge-shaped surfaces are arranged on the cylindrical head screws, and the second wedge-shaped surfaces are attached to the first wedge-shaped surfaces; a second ball head joint is arranged on the second cannula, and the second shaft rods abut against a ball head of the second ball head joint; an instrument chuck is fixedly arranged on the ball head. The universal mechanical instrument support with the screwing and locking function has the advantages that the workload of a doctor is reduced, the work efficiency of the doctor is improved, the shake caused when all instruments are manually supported is avoided, and the stability and precision of an operation are improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a universal medical equipment bracket with screwing and locking functions. Background technique [0002] In the process of modern medical surgery, many advanced medical devices and related equipment have been added. For example, endoscopic equipment in minimally invasive surgery, intraoperative irrigation tubes, retractors and other instruments, the fixation of these devices has always troubled doctors. Hand-held by the doctor. For long-term operations, the assistant doctor needs to hold one or more devices with his hands and maintain a posture for a long time. This is especially true for the endoscopic system in fixed minimally invasive surgery. Many difficulties have also increased the workload of doctors, and more importantly, they have taken up the resources of an auxiliary doctor. It is impossible to allow one doctor to fully play its role, and often requires m...

Problems solved by technology

For example, endoscopic equipment in minimally invasive surgery, intraoperative irrigation tubes, retractors and other instruments, the fixation of these devices has always troubled doctors. Hand-held by the doctor. For long-term operations, the assistant doctor needs to hold one or more devices with his hands and maintain a posture for a long time. This is especially true for the endoscopic system in fixed minimally invasive surgery. Many difficulties have also increased the workload of doctors, and more importantly, they have taken up the resources of an auxiliary doctor

It is impossible to allow one doctor to fully play its role, and often requires multiple doctors to assist, which reduces the doctor's work efficiency, and manual hand support cannot avoid shaking, which brings a negative impact on the clarity of the auxiliary imaging system in the entire operation, especially in minimally invasive surgery. Great influence, unable to improve the stability and precision of the operation
