Problems solved by technology

[0004] (1) For patients with sacral foramen stenosis, sacrococcygeal deformity, and sacral fracture, traditional methods are difficult to make accurate judgments on the sacral foramen;
[0005] (2) X-rays need repeated fluoroscopy to determine the direction and depth of the puncture needle. The puncture process takes too long, which increases the pain of the patient and causes more radiation to the patient and the operator.
[0007] (4) The nerve is not or weakly visualized under the X-ray, and it is impossible to judge whether the puncture needle inserted into the neural foramen is parallel to the nerve root, which is not conducive to placing the electrode at the best position, and may affect the postoperative test effect
This patent adopts an assembled structure and considers removing the guide plate while retaining the puncture needle. However, it adopts the form of a cylinder installed on the outer ring of the bottom plate. There is still a certain distance between the end of the guide hole and the skin puncture point, and the whole process of guidance cannot be realized. Puncture, may increase puncture error

Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0044] Such as figure 1 As shown, this embodiment provides a sacral nerve puncture guide for assisting clinical sacral nerve puncture. The sacral nerve puncture guide mainly includes a base plate, an outer guide tube 2 , an inner guide tube 3 and an outer ring 4 . The substrate is composed of one substrate block 1 , or is formed by riveting and connecting multiple substrate blocks 1 . There are multiple outer guide tubes 2, four are provided in this embodiment, and the outer guide tubes 2 are located on the outer side of the substrate; the inner guide tube 3 is coaxially arranged in the outer guide tube 2, and the two form a mating assembly relationship ; The outer ring 4 is used to fix the positional relationship between the inner guide tube 3 and the outer guide tube 2 ; the base plate is...

Abstract

The invention provides a sacral nerve puncture guide plate and a construction method thereof. It includes a base plate, an outer guide tube and an inner guide tube; the outer guide tube is set on the outer surface of the base plate, and the inner guide tube is coaxially set inside the outer guide tube; the inner guide tube runs through the base plate, and the inner guide tube runs through the end surface of one end of the base plate and the inner face of the base plate. The sides are flush. In the sacral nerve puncture guide plate provided by the present invention, one end surface of the inner guide tube that runs through the base plate is flush with the inner surface of the base plate, so that the end face of the inner guide tube directly touches the skin when in use, and can fit the skin surface to realize the whole process of guiding the puncture, avoiding Puncture error.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sacral nerve puncture guide plate and a construction method thereof. Background technique [0002] Sacral neuromodulation (SNM) is a minimally invasive neuromodulation technology that uses interventional technology to continuously apply low-frequency electrical pulses to specific sacral nerves to excite or inhibit neural pathways, thereby achieving the treatment of diseases of downstream effector organs innervated by sacral nerves. The key to sacral neuromodulation is to accurately place the puncture needle into the sacral nerve foramen. [0003] Traditional puncture methods mainly include: X-ray fluoroscopy cross positioning method, sciatic notch hand touch positioning method, transcoccyx tip measurement positioning method and real-time ultrasound-guided puncture positioning method. These puncture methods rely more on the doctor's experience, and often have the follow...
