Abstract
A kind of sacral nerve percutaneous puncture guide, is related to medical equipment technical field, and the solution is to improve the technical issues of puncturing accuracy.The guide includes substrate, multiple positioning through hole are offered on the substrate, the front of substrate is formed with multiple guide posts protruding upward, the axle center of the guide post is formed with the puncture guide hole for axially penetrating through guide post and substrate along guide post, it is formed with a linear for axially penetrating through guide post and substrate along guide post on the guide post and moves needle breach, the cylinder that extends radially to guide post of the shifting needle breach from the one lateral edge guide post of hole wall for puncturing guide hole.Guide provided by the utility model, the clinical application for sacral nerve puncturing operation.
Description
Technical field
The utility model relates to medical equipment technologies, more particularly to a kind of technology of sacral nerve percutaneous puncture guide.
Background technique
In traditional sacral nerve puncturing operation, doctor sacrum hole site is all confirmed in art using C arm machine come determine to puncture into
Pin mark, traditional surgical approaches are all hand operations, found by experience puncture direction and skin in a manner of 60 degree of inclinations angle into
Row puncturing operation.Therefore it generally requires to determine point of puncture repeatedly using C arm machine and punctures direction, delay operating time and cause
Patient or operator absorb extra radiation, and also lack accuracy by empirically determined puncture direction.
Summary of the invention
For above-mentioned defect existing in the prior art, the technical problem to be solved by the utility model is to provide one kind to wear
It is high to pierce accuracy, and sacral nerve percutaneous puncture guide easy to use.
In order to solve the above-mentioned technical problem, a kind of sacral nerve percutaneous puncture guide provided by the utility model, it is special
Sign is: including substrate, multiple positioning through hole is offered on the substrate, the front of substrate is formed with multiple protruding upward lead
Column, the axle center of the guide post are formed with the puncture guide hole for axially penetrating through guide post and substrate along guide post；
It is formed with a linear for axially penetrating through guide post and substrate along guide post on the guide post and moves needle breach, the shifting needle
The cylinder that extends radially to guide post of the breach from the one lateral edge guide post of hole wall for puncturing guide hole.
Further, multiple shifting needle through-holes are offered on the substrate, each shifting needle through-hole is split with the shifting needle on each guide post
The one-to-one connection of mouth enables and punctures the puncture needle in guide hole along the radial direction of guide post, by moving needle breach, shifting needle through-hole
Remove guide post.
Sacral nerve percutaneous puncture guide provided by the utility model carries out puncture needle using the puncture guide hole on guide post
Guiding punctures accuracy height, and the cooperation by moving needle breach, moving needle through-hole, can easily divide puncture needle and guide
From very easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the sacral nerve percutaneous puncture guide of the utility model embodiment.
Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As shown in Figure 1, a kind of sacral nerve percutaneous puncture guide provided by the utility model embodiment, including substrate 1,
Multiple positioning through hole 2 are offered on the substrate 1, the front of substrate 1 is formed with multiple guide posts 3 protruding upward, the guide post 3
Axle center be formed with the puncture guide hole 31 for axially penetrating through guide post 3 and substrate 1 along guide post；
It is formed with a linear for axially penetrating through guide post 3 and substrate 1 along guide post on the guide post 3 and moves needle breach 32,
The shifting needle breach 32 offers on substrate 1 more from the cylinder for extending radially to guide post for the one lateral edge guide post of hole wall for puncturing guide hole
A shifting needle through-hole 4, each shifting needle through-hole 4 are connected to correspondingly with the shifting needle breach 32 on each guide post, so that puncturing in guide hole
Puncture needle can pass through and move needle breach, move needle through-hole and remove guide post along the radial direction of guide post.
The utility model embodiment is used for the clinical application of sacral nerve puncturing operation, its working principles are as follows:
According to the patient CT and MRI of preoperative shooting, design sets the path and direction of puncture needle, reuses 3D printing technique and set
It counts and makes guide；Substrate is fixed on the patient's body surface, the back side of substrate and patient body using each positioning through hole 2 when operation
Surface Mount closes, and each puncture needle used in art is passed through from the puncture guide hole 31 of each guide post 3, is inserted into human body sacrum hole, as
Implant electrode open circuit uses in art, after the needle track accurate positioning of puncture needle, by the cooperation for moving needle breach, moving needle through-hole, makes to wear
Pricker removes guide post, can remove guide.
Claims (2)
