Body surface positioning and puncture guide instrument used in neurosurgery department

Abstract

The invention discloses a body surface positioning and puncture guide instrument used in a neurosurgery department. The instrument comprises bases, wherein the bases are connected with an operating table through screws; two bases are provided; the two bases are arranged parallel to each other; the bases are connected with joints A in a sliding manner; the adjusting joints A are connected with upper and lower scale range poles through rotating shafts; middle parts of upper and lower scale range poles are connected with adjusting joints B in a sliding manner; rear end surfaces of the adjusting joints B are fixed at one ends of reference rods A; adjusting joints C are arranged at the other ends of the reference rods A; the adjusting joints C are connected with one ends of adjusting line rodsA through rotating shafts; the other ends of the adjusting line rods A are connected with limiting transverse rods through screws; the limiting transverse rods are sleeved by guide sleeves; and upperends of the upper and lower scale range poles are connected with adjusting joints D in a sliding manner. The instrument is applied to body surface positioning of intracranial hematoma and swelling pain, and is capable of correctly guiding directions and depths of puncture needles, ensuring that catheters can puncture to hematomae or swelling pain, and achieving precise body surface positioning onintracranial hematoma.

Description

technical field [0001] The invention relates to the technical field of neurosurgery medical instruments, in particular to a neurosurgery body surface positioning and puncture guide. Background technique [0002] At present, commonly used brain stereotaxic instruments all need to first install a frame outside the head, and then carry out CT or MRI scanning with this frame and the patient, and then obtain the CT or MRI image of the patient's brain with frame coordinate parameters , each image anatomical structure in the patient's brain will have a corresponding coordinate value in this coordinate system, and then reach the coordinate point through the mechanical data defined by the stereotaxic instrument, so as to realize the stereotaxic brain, which has the advantage of high precision , the disadvantage is that the operation is cumbersome and time-consuming. First, it takes a long time to install the invasive head frame. Second, after the head frame is installed, the patient...

AI Technical Summary

Problems solved by technology

[0002] At present, commonly used brain stereotaxic instruments all need to first install a frame outside the head, and then carry out CT or MRI scanning with this frame and the patient, and then obtain the CT or MRI image of the patient's brain with frame coordinate parameters , each image anatomical structure in the patient's brain will have a corresponding coordinate value in this coordinate system, and then reach the coordinate point through the mechanical data defined by the stereotaxic instrument, so as to realize the stereotaxic brain, which has the advantage of high precision , the disadvantage is that the operation is cumbersome and time-consuming

First, it takes a long time to install the invasive head frame. Second, after the head frame is installed, the patient needs to be transferred again to the imaging department for CT or MRI examination. Third, it is not easy to adjust the target at any time during the operation. , Fourth, it is difficult to sterilize and spread towels, and it is not easy to ensure sterility

Fifth, the price is expensive

In addition, there are frameless stereotaxic systems, that is, neuronavigation systems. At present, most products on the market are optical surgical navigation systems. The main disadvantages are that they are very expensive, and they need to be marked and rescanned before surgery. In addition, the accuracy is not as good as that with frames. stereotaxic system

[0003] At present, there are many deficiencies in the frame-based stereotaxic system, which cannot correctly guide the direction and depth of various punctures, cannot guarantee that the catheter can puncture hematoma or swelling pain, cannot realize accurate body surface positioning of intracranial hematoma, and cannot correctly guide various puncture catheters The correct intracranial walking, unable to achieve multi-point positioning selection of external puncture, complex equipment, inconvenient selection of clinical use
