Abstract
本实用新型公开了一种微创脑室穿刺套管针，其技术方案的要点是，其包括针管体，针管体内设有通孔，在通孔内插设有针芯体，在针管体外套设有可使针管体前端伸出其外的柔性引流管。本实用新型目的是克服了现有技术中术器械复杂，创伤大，并发症较多，技术条件要求高的不足，提供一种手术操作容易、费时少、创伤小、并发症少、创口愈合快的脑室穿刺套管针。
The utility model discloses a minimally invasive ventricular puncture trocar, the key points of the technical solution are that it comprises a needle tube body, a through hole is provided in the needle tube body, a needle core body is inserted in the through hole, and a flexible drainage tube is provided on the outer sleeve of the needle tube body so that the front end of the needle tube body can extend out of it. The purpose of the utility model is to overcome the shortcomings of the prior art, such as complex surgical instruments, large trauma, many complications, and high technical requirements, and to provide a ventricular puncture trocar that is easy to operate, less time-consuming, less traumatic, less complicated, and faster wound healing.
Description
[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.

Fig. 3 is a front view of the present utility model;
Fig. 4 is a cutaway view of the present utility model.
[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.
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.
