Embodiment 1

[0029] like figure 1 and image 3 As shown, the present invention provides a puncture device for positioning intracranial lesions, which includes a support frame 100, three positioning blocks 200 slidingly connected to the support frame 100, a puncture mechanism 300 movably connected to the support frame 100, a movable and detachable The positioning reference needle 500 disposed on the positioning block 200 and the first locking component that locks the positioning block 200 on the support frame 100 . The support frame 100 is semicircular. When the support frame 100 is fixed on the patient's head through the positioning block 200, the semicircular support block can be adapted to the concave and convex of the patient's head, so that the support frame 100 is more secure when fixed on the patient's head. Stablize. When the support frame 100 needs to be fixed on the patient's head, the positioning reference pin 500 can be removed from the positioning block 200, and when position...

Embodiment 2

[0040] like figure 1 , image 3 and Figure 5 As shown, the present invention provides a skull drilling positioning device, which includes the intracranial lesion positioning and puncture device described in Embodiment 1, and also includes a head covering 400, the head covering 400 A plurality of marking lines 430 parallel to each other are provided on the outer wall, and the marking lines 430 are coated with a reflective coating; each of the marking lines 430 is provided with at least three positioning holes 440 for accommodating the skull pin 700 . The head wrap 400 is used to be sleeved on the patient's head, and the skull pin 700 is inserted into the patient's skull through the positioning hole 440 for fixation. The spacing between each marking line 430 is approximately equal to the spacing of the CT scan, and the marking line 430 is used as a reference line during the CT scanning.

[0041] In order to facilitate removing the head cover 400 from the patient's head witho...

Abstract

The invention relates to the technical field of medical instruments, in particular to an intracranial lesion positioning and puncture device. The device comprises a supporting frame, at least three positioning blocks slidably connected to the supporting frame, a puncture mechanism movably connected to the supporting frame, positioning reference pins movably and separably arranged on the positioning blocks and a first locking assembly fixedly locking the positioning blocks on the supporting frame. The intracranial lesion positioning and puncture device has the advantages that the puncture angleand puncture distance of the puncture mechanism are determined through the relative positions of the positioning blocks and lesion point, the operation is simple, complicated calculation is not required when the intracranial lesion of a patient is positioned, and the positioning accuracy is higher. The invention also provides a skull drilling and positioning device. The device comprises the intracranial lesion positioning and puncture device and a head circumference sleeve, wherein the outer wall of the head circumference sleeve is provided with a plurality of marking lines which are parallelto one another, and the marking lines are coated with reflective coatings; each marking line is provided with at least three positioning holes used for containing skull nails. The skull drilling andpositioning device is simple to operate and high in positioning precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracranial lesion positioning and puncture device and a skull drilling positioning device. Background technique [0002] With the improvement of people's living standards and the gradual aging of the people in our country, the number of patients with hypertension and intracranial hemorrhage is increasing year by year, especially severe intracranial hemorrhage, which directly endangers the lives of patients. One of the key points of minimally invasive debridement of intracranial lesions is the accurate positioning of lesions, and the positioning method is also a difficulty in minimally invasive surgery. At present, there is no device on the market that can easily and accurately locate intracranial lesions. Contents of the invention [0003] The purpose of the present invention is to provide a puncture device for positioning intracranial lesions. The device has the c...
