Embodiment 1

[0047] The embodiment of the present invention provides a guide device for minimally invasive deep brain surgery. The guide device includes: a guide bracket 1, a mask guide plate, a guide needle and a retractor catheter; the guide bracket 1 is installed on the mask guide plate; the guide needle can Inserted into the retractor catheter, the retractor catheter is detachably fixedly connected with the guide bracket 1; the mask guide plate is fitted and fixed on the skin of the patient's head, and the guide needle and the retractor catheter can be inserted into the patient's brain. In actual use, the embodiment of the present invention also uses a guide clip and a positioning pin adapter tube, which can be fixed on the guide bracket 1 and used for relative fixing of the guide pin and the guide bracket 1 .

[0048] Such as figure 1As shown, the guide bracket 1 is a guide bracket 1 for retracting catheters for brain minimally invasive surgery. The guide bracket 1 includes: a mountin...

Embodiment 2

[0081] An embodiment of the present invention provides a guiding method for deep brain minimally invasive surgery. The guiding method uses the guiding device for deep brain minimally invasive surgery in Embodiment 1.

[0082] The steps of the guided method include:

[0083] S1. Make a mask guide plate through 3D printing technology;

[0084] Input the patient's head CT image data into the 3D printing software. According to the details of the case, determine the designed surgical approach, that is, the insertion direction, target point and posture of the guide needle; design the head mask guide in the 3D printing software according to the set surgical approach, that is, determine the use of the frontal facial mask guide 2 or Go around the auricle mask guide 3 and the position of the mounting seat, and perform 3D printing to obtain the mask guide.

[0085] S2, the guide bracket (1) is installed on the mask guide plate;

[0086] Insert the guide clip and the positioning pin adap...

Abstract

The invention relates to a guide device and guide method used for minimally-invasive deep brain surgery, and belongs to the technical field of minimally-invasive brain surgery equipment. The problem that existing devices are liable to cause damage to brain tissue of patients is solved. The guide device comprises a mask guide board, a guide support, a guide needle and a retraction catheter, whereinthe mask guide board can be fixedly attached to skin of the head of a patient, the guide support is installed on the mask guide board, and the mask guide board and the guide support are detachably and fixedly connected; the guide needle can enter the brain in a guide direction of the guide support; and the retraction catheter can reach a preset position in the brain along the guide needle. According to the guide device and guide method used for the minimally-invasive deep brain surgery, shaking of the retraction catheter in a process of entering the brain is prevented so that not only can thedegree of damage to the brain tissue in an insertion process of the retraction catheter be reduced, but also the accuracy of an insertion position of the retraction catheter in the brain can be further improved. Meanwhile, by means of conical design of the front end of a core of the retraction catheter, damage to the brain tissue in the entering process of the retraction catheter is further reduced, and the position is more accurate.

Description

technical field [0001] The invention relates to the technical field of deep brain minimally invasive surgery equipment, in particular to a guiding device and guiding method for deep brain minimally invasive surgery. Background technique [0002] Brain retractors are often required for minimally invasive surgery in the deep brain. There are two main types of existing deep brain retractors. [0003] A class is called a disposable tissue expander (for example: produced by Beijing Tianxinfu). Double-chamber design, the endoscope used in the operation is relatively fixed (limiting the flexible use of the endoscope), and the catheter is straight (the depth and diameter are the same) design (and the diameter of the tube is tapered from shallow to deep, which is more convenient than this design for both sides of the operation. Use the instrument together), the cross-section is circular (compared with the oval design to push away more brain tissue that does not need to be pushed awa...
