Intracranial hematoma positioning membrane and positioning device

Abstract

The invention discloses an intracranial hematoma positioning membrane and a positioning device. The positioning device comprises a base layer, multiple labeled holes are formed in the base layer regularly, CT labels are arranged on the labeled holes, and the density of the labeled holes in the base layer is larger than 0.7 per cm<2>. According to the intracranial hematoma positioning membrane and the positioning device, the base layer is attached to the surface skin, corresponding to hematoma, of a patient, an accurate relative position of the hematoma and the base layer is obtained through CT, and accordingly a suitable target labeled hole is selected in the base layer through the relative position and marked on the scalp of the patient, so that the obtained target label hole is the puncture hole. The positioning device is simple in structure and easy to operate and can be positioned precisely.

Description

technical field [0001] The invention relates to intracranial puncture technology, in particular to an intracranial hematoma positioning membrane and a positioning device. Background technique [0002] For intracranial hematoma, the current main treatment methods include microsurgical removal, ventriculoscopic hematoma removal, and puncture drainage. Among them, puncture drainage is the most widely used because of its small trauma, quick recovery, and definite curative effect. In puncture and drainage, the location of the puncture point during puncture is one of the key factors that determine the success of the operation. [0003] The puncture positioning of puncture and drainage in the prior art mainly has the following methods: [0004] 1. Stereotaxic instrument, for example, the application number is 201610335720.2, the publication date is 2016.08.10, and the invention patent application named "a three-dimensional stereotaxic numerical control surgical device" provides su...

AI Technical Summary

Problems solved by technology

[0007] The disadvantages of the prior art are that the stereotaxic instrument is expensive, the structure is complex, and the operation is cumbersome; the positioning frame is difficult to locate accurately, and the probability of large errors is too high; The center of the hematoma cannot be accurately located if it is tilted, and even if the marking is accurate, the metal marker needs to be torn off and then marked with a marker pen, which cannot be marked in real time
