Abstract
The utility model provides an auxiliary device of a neuroendoscopic operation channel for double-needle core brain puncture, which adopts a double-needle core telescopic novel design, during brain puncture, a fine needle core is removed firstly, and a thick needle core is removed, so that no negative pressure suction force is generated. The auxiliary device comprises an external pin and needle cores mounted inside the external pin, the needle cores comprises a fine needle core and a thick needle core, the fine needle core is mounted in the thick needle core, and both the two needle cores are mounted in the external pin. A needle sewing hole is formed on the external pin. An external pin fixing arm is arranged at one end of the external pin. Two brain tissue traction plates are mounted on the external pin, and internal pins are mounted in the brain tissue traction plates. The brain tissue traction plates form a U-shaped opening, and the other end of the external pin is connected with a ring-shaped bracket. Scale marks are arranged on the surface of the external pin. The auxiliary device is used in cranial nerves surgical operation.
Description
Technical field:
This utility model relates to the auxiliary sleeve pipe that cerebral surgery operation is used, and exactly is a kind of crosspointer core brain puncture nerve endoscope operation path auxiliary device.
Background technology:
Neurosurgery such as deep intracerebral hematoma, intraventricular hematoma adopt evacuation of hematoma under the nerve endoscope, need row cerebral tissue piercing method to set up operation path and operate in passage for nerve endoscope and operating theater instruments and reach therapeutic purposes.Present stage carries out this type of operation and solving the following method of the normal employing of operation path problem: (1) is passed through the hematoma of suction certain volume and is interrupted the normal saline washing brain essence inner chamber of using certain pressure, form narrow and small lacuna, realize the operation of nerve endoscope light source, surgical field of view there is certain help, but this method effect is undesirable, usually cause drainage channel obstruction, nerve endoscope light source camera lens easily to stain, the consequence that camera lens can't accurately be treated focus, bring very big inconvenience to operation technique, influence therapeutic effect.(2) the duroplasts syringe epitheca pruning of interim employing aseptic packaging is made in operation, but because of it belongs to non-special product, is difficult to well satisfy the operation technique needs, influence operation quality, and the brain tissue impairment that causes in the use is bigger.(3) the existing Related product of application market: structure is the simple designs of bodkin core retainer plate epitheca, the brain of being expert at puncture, when extracting the bodkin core, because the bigger negative pressure-pumping power of airtight generation, easily cause brain tissue impairment or bring out angiorrhexis hemorrhage, lack fixed structure and matching used other adnexa, need hold with hand steered all the time by surgical staff, influence operation technique, increased the difficulty of operation.The patent that a kind of name is called " the auxiliary sleeve pipe of a kind of brain surgical endoscope treatment " is disclosed as China Patent No. " 200720172667.5 ", it is made up of trocar sheath, bracing frame, sound-pipe, tube core, drainage tube and drainage bag, bracing frame is provided with the elastic guard plate of fixing support rack, wherein trocar sheath is fixedlyed connected with bracing frame, bracing frame and sound-pipe constitute axially displaceable flexible connection, drainage tube and tube core can be separately positioned in the sound-pipe by application target, drainage tube and trocar sheath constitute axially displaceable flexible connection, and drainage tube is communicated with drainage bag.Though have certain effect, also be difficult to solve tube core and take out the negative pressure-pumping power problem that the back produces, be difficult to well satisfy the action need of brain hematoma operation.
Summary of the invention
The purpose of this utility model provides a kind of crosspointer core brain thorn with nerve endoscope operation path auxiliary device and adnexa, has good fixed structure, solves the deficiencies in the prior art.Well satisfy the action need of brain hematoma operation.
The technical scheme that this utility model technical solution problem is adopted is: crosspointer core brain puncture nerve endoscope operation path auxiliary device, it comprises export trade and is contained in inner nook closing member, nook closing member and is made up of bodkin core and fine needle core, the fine needle core is contained in the bodkin in-core, and they are contained in the export trade together.Have the suture needle hole on the epitheca.Epitheca one end has the epitheca fixed arm.Epitheca is equipped with two cerebral tissue drawing plates, and interior sheath is housed in the cerebral tissue drawing plate.Two cerebral tissue drawing plates are formed the U-shaped opening, and the other end links to each other with ring support.There is scale marker on the epitheca surface.
The utility model has the advantages that
(1) adopts crosspointer core telescopiform new design, during the brain of being expert at puncture, can pull out the fine needle core earlier, extract the bodkin core again, no longer produce negative pressure-pumping power;
(2) fine needle core hole can connect syringe and finish operations such as experiment suction, a small amount of tapping;
(3) have good fixed structure, promptly epitheca fixed arm card is pressed on the lamina externa cranii on every side of bone hole, temporarily is sutured in stationary conduit epitheca in the surrounding soft tissue by the suture needle hole, uses more convenient operation.
(4) this install all members once the operation in can repeatedly use repeatedly
(5) special-purpose cerebral tissue drawing plate, be to adopt high-tension, hypermnesia to recall foil and make, insert in the intermediary passage of epitheca after the available hands bending, after inserting fully, front end opens automatically by metal self elastic force, interior sheath is inserted fix again, can reach the outwards effect of tractive cerebral tissue of appropriateness by lifting epitheca, thereby enlarge the visible space of nerve endoscope and working place, the raising operation quality of operating theater instruments, make the cerebral tissue tractive be easy to pull out by passage.
