Description

Technical Field

[0001] This utility model belongs to the field of ventricular puncture stents, specifically a ventricular puncture auxiliary stent. Background Technology

[0002] Hydrocephalus is a common neurosurgical disease. Ventriculoperitoneal shunt is the standard treatment for hydrocephalus. There are three approaches for ventricular catheter insertion: frontal horn, trigone, and occipital horn. Frontal horn puncture offers advantages such as convenient surgical positioning; the ability to extend the existing incision during frontal craniotomy; clearer anatomical landmarks of the coronal and sagittal sutures; larger frontal horns of the lateral ventricles without choroid plexus; no compression of the incision and drainage tube after surgery; the incision is located behind the hairline, which does not affect aesthetics; and the transverse incision behind the hairline in the frontal region can be extended to the opposite side, making it easier to choose the opposite side for puncture when it is difficult to puncture on one side.

[0003] During the puncture procedure, the patient should be in a supine position. The puncture point is 1 cm anterior to the coronal suture and 2.5 cm lateral to the midline. The puncture direction is parallel to the sagittal plane, aligned with the line connecting the two external auditory canals. The puncture depth is 4-6 cm. However, during the puncture, the line connecting the two external auditory canals usually depends on the experience of the puncturist, making it difficult to guarantee the puncture direction. If the direction is incorrect, the puncture will fail, thus affecting the puncture treatment.

[0004] In summary, this utility model provides a ventricular puncture auxiliary stent to solve the above problems. Utility Model Content

[0021] Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a ventriculoperitoneal puncture auxiliary stent, including a locking component 1. A puncture needle guide groove 2 is fixedly connected to the top of the locking component 1. The puncture needle guide groove 2 is used to guide the puncture needle. A positioning component 3 is also installed on the surface of the locking component 1. There are three positioning components 3, which are used for positioning the bilateral ear canals and the brow ridge, respectively. The locking component 1 includes a fixing block 101, a first guide hole 102, a second guide hole 103, a first threaded hole 104, and a first fastening bolt 105. The first guide hole 102 and the second guide hole 103 are used to guide the positioning component 3. The first threaded hole 104 and the first fastening bolt 105 are used to fix the positioning component 3. The positioning component 3 includes a guide rail 301, a positioning block 302, a sliding groove 303, a second threaded hole 304, and a second fastening bolt 305. The guide rail 301 is used to provide support for the positioning block 302. The second threaded hole 304 and the second fastening bolt 305 are used to fix the positioning block 302.

[0023] like Figure 1-4As shown, the two sets of positioning components 3 can be used to locate and connect the left and right ear canals, thereby ensuring the puncture position. The two ear canals are positioned using the positioning components 3 on both sides. The guide rails 301 are pulled in opposite directions, causing them to slide along the inner cavity of the second guide hole 103, bringing the positioning block 302 into contact with the head. Then, the first fastening bolt 105 is rotated, causing it to move downwards along the inner cavity of the first threaded hole 104, thus fixing the guide rails 301 on both sides. Pull the positioning block 302 up or down to adjust its position so that the positioning blocks 302 on both sides are located in the left and right ear canals respectively. Then rotate the second fastening bolt 305 so that the second fastening bolt 305 rotates along the inner cavity of the second threaded hole 304 into the inner cavity of the slide groove 303 and fits tightly with the guide rail 301, thereby fixing the positioning block 302 and connecting the left and right ear canals. The eyebrow arch position can be positioned by another set of positioning components 3, thereby avoiding errors in the puncture position.

The second guide hole 103 is used to guide the guide rail 301 for positioning the left and right ear canals, and the first guide hole 102 is used to guide the guide rail 301 for positioning the brow ridge. The positioning component 3 can be fixed after positioning by the cooperation of the first threaded hole 104 and the first fastening bolt 105, thereby avoiding the situation where puncture failure occurs due to incorrect puncture direction.

[0032] In use, first, the two ear canals are positioned using the positioning components 3 on both sides. Then, the guide rails 301 are pulled in opposite directions to slide along the inner cavity of the second guide hole 103, bringing the positioning block 302 into contact with the head. Next, the first fastening bolt 105 is rotated, moving downwards along the inner cavity of the first threaded hole 104 to fix the guide rails 301 on both sides. Then, the positioning block 302 is pulled up or down to adjust its position, positioning it in the left and right ear canals respectively. Finally, the second guide rail 302 is rotated... Tighten bolt 305 so that the second fastening bolt 305 rotates along the inner cavity of the second threaded hole 304 into the inner cavity of the slide groove 303 and fits tightly with the guide rail 301, thereby fixing the positioning block 302 and connecting the left and right ear canals. Then, the inner corner of the eyebrow arch is positioned by another positioning component 3. Pull the guide rail 301 so that the guide rail 301 slides along the inner cavity of the first guide hole 102. After adjusting the positioning block 302 to the position of the inner corner of the eyebrow arch, fix it by the above steps, thereby enabling puncture positioning and avoiding puncture failure due to incorrect puncture direction.
