Description

Three-stage puncture cannula assembly for trigeminal semilunar ganglion balloon compression

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a three-stage puncture cannula assembly for trigeminal semilunar ganglion balloon compression surgery.

Background

The trigeminal semilunar ganglion balloon compression operation is completed through a puncture cannula assembly, and comprises the first step of puncturing into a foramen ovale; secondly, finding the trigeminal semilunar ganglion in the oval hole; and thirdly, pressing the semilunar ganglion to ensure that the semilunar ganglion of the trigeminal nerve is subjected to ischemic necrosis, thereby realizing the aim of treatment.

The puncture cannula tool used for clinical treatment at present uses a puncture trocar with a thicker inner diameter ratio to penetrate into a foramen ovale, and has the main defects that: (1) when the puncture cannula is used for operation, general anesthesia is needed, and the operation risk and cost are increased; (2) the puncture needle is thicker, the tip is more round and blunt, the pain of a patient is larger, and the injury is larger; (3) is not favorable for puncturing the Mylar sac (with the semilunar junction of the trigeminal nerve inside), so that the saccule is difficult to enter the Mylar sac and press the semilunar junction, which causes the unsatisfactory operation effect! Therefore, a puncture cannula assembly with small trauma and ideal effect is needed to be used for trigeminal semilunar ganglion saccule compression surgery.

Disclosure of Invention

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a tertiary puncture thimble assembly for trigeminal nerve semilunar ganglion sacculus oppression art, this subassembly include the puncture needle core, prevent stifled needle core, sacculus pipe and outer tube, the puncture needle core is cavity column structure to its front end is sharp-pointed, and the tail end can be dismantled and is equipped with the connecting seat, prevent that the interlude that stifled needle core can be pulled out sets up in the inside of puncture needle core, the front end of sacculus pipe is equipped with the sacculus, the outer tube is cavity column structure to the smooth circle of front end of outer tube is blunt, and the internal diameter of outer tube is greater than the external diameter of puncture needle core and sacculus pipe.

Furthermore, the assembly also comprises an extension guide wire, an annular boss is arranged at the front end close to the extension guide wire, the diameter of the annular boss is the same as that of the puncture needle core or the diameter of the annular boss is larger than that of the puncture needle core and smaller than the inner diameter of the outer sleeve.

Furthermore, the front end of the connecting seat is inserted at the tail part of the puncture needle core in an interference fit mode, an anti-leakage sealing area is arranged on the inner wall of the insertion part, and the rear end of the connecting seat is used for being connected with a syringe for injecting anesthetic.

Furthermore, the anti-blocking needle core is of a solid structure, and a handheld operation end convenient for plugging and unplugging is arranged at the tail of the anti-blocking needle core.

Furthermore, the sacculus pipe is made of soft transparent materials, and the sacculus at the front end of the sacculus pipe expands when liquid is injected or inflated.

Furthermore, the outer walls of the sacculus tube and the outer sleeve are provided with marking lines.

The invention has the following beneficial effects:

(1) the front end of the puncture needle core is arranged into a tangent plane, so that the front end of the puncture needle core is sharper, the puncture needle core is favorable for puncturing the Mycosphaeredema, the saccule of the saccule tube at the back can enter the Mycosphaeredema, and compared with the existing method of directly puncturing the saccule by using a sleeve, the puncture needle core has the advantages of smaller diameter, smaller injury and less pain for patients.

(2) The invention not only reduces the wound surface in the puncture process, but also greatly reduces the difficulty of the puncture needle in puncturing the Mycosphaeremia sac, and improves the success rate of the operation.

(3) The puncture needle core is internally of a hollow structure, a connecting seat at the tail part of the puncture needle core can be connected with an injector for injecting the anesthetic, and the puncture needle core can be taken down after the anesthetic is injected, so that the later operation is not influenced; therefore, local anesthesia can be performed on the semilunar ganglion by using anesthetic inside the stylet, so that a good local anesthesia effect can be achieved, general anesthesia is avoided, and the cost and risk of the operation are greatly reduced.

(4) The anti-blocking needle core is arranged in the invention, so that the puncture needle core can be prevented from being internally blocked in the puncture process, and further the anesthesia injection operation carried out later is influenced.

(5) The tail end connecting seat of the puncture needle core is detachably designed, can be used as a guide wire for guiding the outer sleeve after being detached, simultaneously considers the problem that the guide length is not enough and the operation is inconvenient, and also adds an extension guide wire, the front end of the extension guide wire can be inserted into the tail end of the puncture needle core, and the annular boss can play a role of limiting, so that the length of the guide wire can conveniently reach 2-3 times of the length of the outer sleeve, and the convenience of the operation of the outer sleeve is greatly improved.
