Abstract

The utility model discloses a minimally invasive ventricular puncture trocar. The key points of the technical scheme of the utility model are that the minimally invasive ventricular puncture trocar comprises a needle tube body a through hole inside which is disposed, a needle core body is inserted in the through hole and a flexible drainage tube is disposed on the outer sleeve of the needle tube body and enables the front end of the needle tube body to project outside the outer sleeve of the needle tube body. The purpose of the utility model is to overcome the shortcomings that the operation apparatus in prior art is complex, the wound is big, the complications are comparatively large in amount and the demands of the technical condition are high, thereby providing a ventricular puncture trocar with easy operation, short term, small wound, few complications and soon healed wound.

Description

A kind of Wicresoft ventricular puncture trocar

[technical field]

This utility model relates to a kind of medical apparatus and instruments, a kind of ventricular puncture trocar of saying so more specifically.

[background technology]

Brain is positioned at the cranial cavity of sealing, and cerebral tissue edema, cerebrospinal fluid supersecretion, circulation or malabsorption, cerebral hemorrhage and intracranial space-occupying lesion can make intracranial pressure raise, and cause central nervous system dysfunction even death.Therefore, lateral cerebral ventricle puncture drainage of cerebrospinal fluid and monitoring intracranial pressure be an important content of Intensive Care Therapy and first aid, its key point is to need to place a drainage tube at lateral cerebral ventricle puncture.The tradition tricorn is put drainage tube and need be cut scalp, and the cranium of diameter 1.0～1.5cm bores and opens skull, enters the ventricles of the brain with ventricles of the brain lancet puncture then, extracts the brain pin again, inserts diameter 3～5mm ventricular drainage tube separately along puncture path and finishes.Penetrate the ventricles of the brain whether because of observing, the brain pin repeatedly must be extracted, increase patient's pain of injury.Need in the art with the specific process hemostasis, wound need be sewed up.The operating theater instruments complexity, wound is big, and complication is more, and technical conditions require high, need have certain operating room condition, thereby cause this technology to be used in the emergency treatment first aid being restricted.

[utility model content]

This utility model purpose is to have overcome art apparatus complexity in the prior art, and wound is big, and complication is more, and the demanding deficiency of technical conditions provides the ventricular puncture trocar that a kind of operation technique is easy, time-consuming less, wound is little, complication is few, wound healing is fast.

This utility model is achieved through the following technical solutions:

A kind of Wicresoft ventricular puncture trocar, it is characterized in that: it comprises needle tube body, is provided with through hole in the needle tube body, is inserted with the nook closing member body in through hole, is arranged with to make the needle tube body front end stretch out flexible drainage tube outside it outside needle tube body.

Aforesaid a kind of Wicresoft ventricular puncture trocar is characterized in that the rear end of described needle tube body is provided with the Handheld Division.

Aforesaid a kind of Wicresoft ventricular puncture trocar is characterized in that the rear end of described nook closing member body is provided with the Handheld Division, and front end is provided with hemisphere face, and described hemisphere face stretches out outside the needle tube body.

Compared with prior art, this utility model has following advantage:

1, this utility model is simple in structure at self-control ventricular puncture trocar equipment, only is made up of nook closing member body, needle tube body, drainage tube;

2, this utility model reaches the Minimally Invasive Surgery requirement, and surgical wound is very little, and postoperative wound need not special handling; Time-consuming less, wound is little, complication is few, wound healing is fast, the security performance height.

3, this utility model constitutes an integral body with puncture needle and drainage tube in the mode of the trocar, can insert drainage tube in the time of ventricular puncture, and therefore simple to operate, it is comparatively safe to perform the operation, and complication is few, and bedside can be operated.

[specific embodiment]

A kind of Wicresoft ventricular puncture trocar, it comprises needle tube body 1, is provided with through hole 101 in the needle tube body 1, is inserted with nook closing member body 2 in through hole 101, is arranged with to make needle tube body 1 front end stretch out flexible drainage tube 3 outside it outside needle tube body 1.The rear end of needle tube body 1 is provided with Handheld Division 102, and the rear end of nook closing member body 2 is provided with Handheld Division 201, and front end is provided with hemisphere face 202, can avoid stabbing cerebral vessels, and described hemisphere face 202 stretches out outside the needle tube body 1.

Needle tube body 1, nook closing member body 2, drainage tube 3 are set on together, and drainage tube 3 overall diameters can be as small as 1.6mm.Drill bit with diameter 2.5mm; install the simple and easy protector of a scalable controlling depth additional; during clinical practice; directly pierce through the scalp sphenotresia with drill bit; then paracentesis trocar is punctured into the ventricles of the brain by the sphenotresia place; observe and have or not cerebrospinal fluid to flow out to determine whether to penetrate the ventricles of the brain by extracting nook closing member body 2 in the piercing process, in case determine to enter the ventricles of the brain, extract thread a needle body 1 and nook closing member body 2 indwelling drainage tubes 3 in Intraventricular for drainage of cerebrospinal fluid or monitoring intracranial pressure.Operation has only diameter 2.5mm point-like penetration damage at scalp skull wound surface, need not to sew up hemostasis.

This utility model is simple and practical, only is made up of nook closing member body 2, needle tube body 1, drainage tube 3, and auxiliary facilities only needs a skull drill bit, can reach the Minimally Invasive Surgery requirement, wherein the thickest is drill bit, and diameter only is 2.5mm, therefore surgical wound is very little, and postoperative wound need not special handling.Brain puncture needle and drainage tube are constituted an integral body in the mode of the trocar, can insert drainage tube 3 in the time of ventricular puncture, therefore simple to operate, it is comparatively safe to perform the operation, and complication is few, and bedside can be operated.
