Frameless locator for minimally invasive surgery in neurosurgery department

Abstract

The invention discloses a frameless locator for a minimally invasive surgery in the neurosurgery department, and relates to the field of the neurosurgery department. The frameless locator for the minimally invasive surgery in the neurosurgery department comprises a bed body; the bottom of the bed body is fixedly connected with a first standing plate and a second standing plate; the first standingplate and the second standing plate are located on the head side and the tail side of the bottom of the bed body respectively; a lead screw is rotationally connected between the first standing plate and the second standing plate through a bearing; the lead screw is sleeved with a horizontal positioning block; a threaded hole is formed in the horizontal positioning block; the horizontal positioningblock is in threaded connection with the lead screw through the threaded hole; a transverse supporting plate is fixedly connected to the side wall of the horizontal positioning block; and a supporting block is fixedly connected to the bottom of the bed body. According to the frameless locator for the minimally invasive surgery in the neurosurgery department, before a puncture needle is inserted into a cannula, the puncture angle, position and height of the cannula can be adjusted in advance, so that a beginner can operate conveniently, the phenomenon of surgical failure caused by incorrect insertion position and angle of the puncture needle is prevented, and the pain of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of neurosurgery, in particular to a frameless locator for minimally invasive neurosurgery. Background technique [0002] Puncture surgery is a relatively common operation in clinical surgery. Usually, the main reason for the failure of puncture surgery is the wrong puncture position and direction. The realization is that after the doctor measures the relative positional relationship between the lesion position in the patient's medical image and the marker on the patient's head, and then performs a corresponding comparative measurement on the patient's head in the real environment, the patient's needle insertion point and direction are determined. [0003] In the prior art, doctors mostly rely on experience and feeling when performing puncture, and use the puncture needle cylinder to puncture the puncture position and angle. This heavily depends on the doctor's experience and level, which makes it easy for no...

Problems solved by technology

[0003] In the prior art, doctors mostly rely on experience and feeling when performing puncture, and use the puncture needle cylinder to puncture the puncture position and angle. This heavily depends on the doctor's experience and level, which makes it easy for novices to puncture failure, and after puncture, The doctor's arm may shake, and the position of the puncture needle cannot be stably fixed, so that the puncture needle may be displaced, which increases the pain of the patient. Aiming at the deficiencies in the prior art, the present invention discloses a neurosurgery minimally invasive Surgical frameless locator to solve the problems raised in the above background technology
