Problems solved by technology

Domestically developed directional instruments are mainly imitations of foreign directional instruments. The common problems of these stereotaxic instruments are: 1. Large volume, complex structure, and high cost; 2. The display and calculation methods for invisible intracranial targets It is complicated and not suitable for critical patients; 3. The frame structure is complicated and the exposure range of the head is small, so it is not suitable for open stereotaxic surgery; 4. It cannot be connected with electric drills and intracranial hematoma crushing needles, etc., and the function is relatively single; 5. After the directional instrument is fixed on the patient's head, it is difficult for the patient to take a lateral or prone position, and the puncture site is in danger, so it is not suitable for operations in various positions
6. There is trauma during the installation of the directional device

Embodiment Construction

[0014] The structure of the present invention is as figure 1 As shown: it is composed of a bow-shaped frame 1, light-emitting heads 2 installed at both ends of the bow-shaped frame, and an electric drill 4 with a puncture needle 3. The puncture needle 3 and the light source head 2 are on a straight line. The above-mentioned light-emitting head 2 is a laser head or other light source heads. The electric drill 4 is socketed with the ring buckle 5 at one end of the bow frame, and the ring buckle 5 is provided with a hanging ear type locking mechanism 6 . The bow frame 1 is made of light material with good stability (strength), and its side length is 19cm×50cm×16cm. (The bow frame can also be made into "C" type)

[0015] Installation of the present invention:

[0016] Fix the micro-laser lamp 2 on one end of the bow frame 1, and connect the other end of the bow frame 1 with the electric drill, and the light and the drill are opposite to each other, so that the laser beam and th...

Abstract

The invention discloses an intracranial piercing laser locator which comprises an arch rack, a light-emitting head arranged on the two ends of the arch rack, and an electric drill with a puncturing needle, the puncturing needle and the light-emitting head are on a same straight line. The device provided by the invention can be connected with electric drills and intracranial hemotoncus suction spindle for piercing treatment for any positions of human body.

Description

technical field [0001] The invention relates to a surgical operation auxiliary tool, in particular to a light locator for intracranial puncture stimulation. Background technique [0002] In recent years, the rapid development of minimally invasive technology and the continuous improvement of puncture needles have made the scope of application of intracranial puncture (drainage) wider and wider, thus replacing many craniotomy operations. But the blindness and deviation of puncture have always troubled doctors. For small lesions, complex lesions or special parts, it is very difficult to achieve accurate puncture. The emergence of stereotaxic technology is one of the important development directions of modern neurosurgery. This technique has the advantages of precise positioning, small additional damage, safety and reliability, etc. It is an essential and important tool for the treatment of functional neurosurgical diseases such as Parkinson's disease, torsion spasm, psychosi...
