Abstract
The utility model provides a minimally invasive abdominal puncture needle of ventricular peritoneal shunt. The puncture needle comprises an inner core puncture needle and a puncture needle sheath, wherein a cavity of the puncture needle sheath is of a semi-closed groove structure; and the inner core puncture needle is inserted into the cavity of the puncture needle sheath to form a sliding pair. The minimally invasive abdominal puncture needle of the ventricular peritoneal shunt is characterized in that the tail part of the puncture needle sheath is provided with a locking pin hole, wherein the tail end of the needle body of the inner core puncture needle is provided with a convex locking pin which is matched with the locking pin hole in the puncture needle sheath. When the minimally invasive abdominal puncture needle is used for a puncture abdominal surgery, peritoneum, muscle and subcutaneous tissues are not required to be sutured; and the skin cut is only 0.5 cm, so that the injury caused to a patient is greatly reduced, and minimal invasion of the ventricular peritoneal shunt is realized. The aims of relieving the injury of the patient and realizing minimal invasion are fulfilled to the greatest extent; and meanwhile, the puncture needle has the advantages that the operation difficulty is reduced, the operation time is saved and postoperative complications are reduced.
Description
Technical field
This utility model discloses a kind of ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle, particularly can be applicable to the semi-enclosed puncture needle of Wicresoft of ventriculoperitoneal shunt midriff operation, belongs to the medical surgical instrument technical field.
Background technology
Ventriculoperitoneal shunt is a kind of hydrocephalic art formula commonly used for the treatment of, and surgical effect is definite.Need open abdomen when previously ventricles of the brain peritoneal shunt pipe is inserted the abdominal cavity and place (abdominal incision is general more than 5 centimetres), this pipe mode of putting, wound is large, operating time is long (approximately 1 ~ 2 hour), and post-operative complication is many, exposes to increase such as intestinal tube and infects probability, the hemorrhage infiltration of edge of wound abdominal cavity increasing plugging probability.In recent years, the auxiliary lower ventricles of the brain peritoneal shunt pipe abdominal end of placing of peritoneoscope has avoided opening the shortcomings such as abdomen placement isocon abdominal end wound is large, but, the isocon abdominal end needs first after the trocar is inserted the abdominal cavity, again that near-end is subcutaneous to head through abdomen, breast, neck, through the one-way distributing pump, be connected with isocon ventricles of the brain end, otherwise the trocar is difficult to break away from isocon.And the auxiliary pipe mode of putting of peritoneoscope can not be in place completely and check under the unobstructed prerequisite in confirmation isocon all fronts at isocon, places the isocon abdominal end by predetermined scheme.
Summary of the invention
This utility model provides a kind of ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle, reaches to alleviate patient's damage, reduce operating difficulty, save operating time, reduce the purpose of post-operative complication.
The ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle that this utility model provides, adopt following technical scheme:
Comprise inner core puncture needle and Puncture needle sleeve sheath, the cavity of Puncture needle sleeve sheath is semiclosed groove structure, and the cavity that the inner core puncture needle inserts the Puncture needle sleeve sheath consists of sliding pair.
Described ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle, it is characterized in that: Puncture needle sleeve sheath afterbody is provided with the pin-and-hole of locking; The needle body end of inner core puncture needle is provided with the convex lock pin and matches with the pin-and-hole of locking of Puncture needle sleeve sheath.
Described ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle is characterized in that described ventricles of the brain peritoneal shunt Wicresoft abdominal puncture needle, and it is characterized in that: inner core puncture needle end is provided with hand rest, and the Puncture needle sleeve sheath is provided with handle.
Good effect of the present utility model is: when perform the operation in the puncture abdominal cavity, without peritoneal suture, muscle, subcutaneous tissue, skin incision is 0.5cm only, has greatly reduced the damage that the patient is caused, and has realized the Wicresoft of ventriculoperitoneal shunt.Alleviate to greatest extent patient's damage, realize Wicresoft's purpose, also have the advantage that reduces operating difficulty, saving operating time, reduces post-operative complication simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model inner core puncture needle;
Fig. 3 is the structural representation of this utility model sheath cover;
Among the figure, 1, the inner core puncture needle; 2, Puncture needle sleeve sheath; 3, cavity; 4, hands handle; 5, lockpin hole; 6, lock pin; 7, hand rest.
The specific embodiment:
According to shown in Figure 1, this utility model is comprised of inner core puncture needle 1 and Puncture needle sleeve sheath 2, and wherein, inner core puncture needle 1 is solid construction (referring to Fig. 2), and is slightly long than Puncture needle sleeve sheath 2, and front end is the passivity tip; The cavity 3 of Puncture needle sleeve sheath 2 is semiclosed groove structure (referring to Fig. 3), and the cavity 3 that inner core puncture needle 1 inserts Puncture needle sleeve sheath 2 consists of sliding pair; Puncture needle sleeve sheath 2 afterbodys are provided with the pin-and-hole 5 of locking; The end of inner core puncture needle 1 also is provided with hand rest 7, is convenient to hold, and inner core puncture needle 1 proximal end place is provided with convex lock pin 6, can match with Puncture needle sleeve sheath 2 pin-and-hole 5 of locking.
As shown in Figure 3, Figure 4, have the handle 4 of one on the Puncture needle sleeve sheath 2 with handled easily, the needle body end is provided with hand rest 7, is convenient to hold, and needle body proximal end place is provided with convex lock pin 6, can match with Puncture needle sleeve sheath 2 pin-and-hole 5 of locking.
During use, other about 5 centimetres of the left abdominal part umbilicus of patient, approximately 0.5 centimetre of skin incisions is got this utility model Wicresoft abdominal paracentesis and is needled into.At this moment abdominal puncture needle is in the state shown in Fig. 1: the needle body of inner core puncture needle 1 is positioned at Puncture needle sleeve sheath 2, and lock pin 6 is positioned at lockpin hole 5 and is in the lock state.Because the needle point of inner core puncture needle 1 is blunt nosed, thrusts intraperitoneal and has obvious breakthrough sense.After clearly entering the abdominal cavity, rotate inner core puncture needle 1, lock pin 6 is produced in the lockpin hole enter in the cavity 3, inner core puncture needle 1 is extracted out from Puncture needle sleeve sheath 2 cavitys 3.Isocon is imported the abdominal cavity, after isocon imports fully, rely on " C " shape semi-enclosed cavity 3, isocon is separated with Puncture needle sleeve sheath 2.
