Medical auxiliary robot

Abstract

The invention provides a medical auxiliary robot, which comprises: a fixed connecting device for fixing a structure connected with the tail end of the fixed connecting device; a position adjusting device, wherein the position adjusting device comprises a base, a power structure and at least two sets of moving assemblies, each set of the moving assembly comprises two parts capable of moving relatively, and the power structure can promote the two parts to move relatively; a control device used for regulating the power structure and being in communication connection with the outside; and a guidedevice for limiting the movement path of a surgical instrument, wherein the position adjusting device is connected with the tail end of the fixed connecting device, and the guiding device is hinged tothe two sets of the moving assemblies of the position adjusting device through connecting members, so that the guiding device changes the spatial position according to movement of the two sets of themoving assemblies so as to achieve the positioning of the guiding device in the three-dimensional space. The medical auxiliary robot is small in size, flexible in structure and suitable for being used in cooperation with the existing navigation system, the existing ultrasonic system and the like.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical assistant robot. Background technique [0002] Puncture surgery is one of the common types of surgery in clinical surgery, and its specific applications include but not limited to hematoma aspiration, cyst aspiration, tissue biopsy, drug delivery, etc. [0003] In traditional puncture surgery, the location of the puncture needle is generally confirmed based on the patient's CT image to confirm the location of the lesion, and then the doctor will roughly determine the puncture path according to the location of the lesion and perform the puncture. One CT scan is used to correct the direction of travel of the puncture needle. Therefore, the patient needs to receive multiple CT scans during the entire operation, and the radiation is relatively large. The design of the puncture path in this method relies heavily on the doctor's experience and judgment, and there a...

Problems solved by technology

However, the existing technology has the problem of long preparation time. For operations such as aspiration and biopsy, the use of stereotaxic technology will greatly increase the preparation time for the operation, and is not suitable for emergency operations such as hemorrhagic stroke. Marker scan CT, increasing patient radiation exposure; additional trauma during headgear installation

In addition, stereotaxic surgical robots are expensive and difficult to promote and use in ordinary hospitals, and cannot benefit the majority of patients
