Abstract

The utility model discloses a V-P shunting pipe enterocoelia end cathetering puncture needle. The V-P shunting pipe enterocoelia end cathetering puncture needle is composed of a puncture needle with a passivity inner core and a sheath pipe which can be avulsed and prolapse in a splitting mode. The head end of the passivity inner core is obtuse, a baffle is arranged on the one-quarter position of the top end of the passivity inner core, and the puncture needle is sleeved below the baffle of the passivity inner core. The tip end of the puncture needle does not exceed the head end of the passivity inner core, a spring is sleeved above the baffle, a bolt is sleeved on the periphery of the spring, an inner core clamping groove and a buckling platform are arranged on the outer wall of the bolt, the inner core clamping groove is connected with a bolt cap, the buckling platform corresponds to the baffle, and a connection joint is arranged at the tail end of the passivity inner core. The sheath pipe which can be avulsed and prolapsed in the splitting mode is composed of two symmetric semicanalis with handles, the semicanalis are made of hardness polyvinyl chloride (PVC) materials, the semicanalis are connected through multiple point-shaped structures, and under the effect of external force, the two semicanalis can be easily separated. Compared with the prior art, the V-P shunting pipe enterocoelia end cathetering puncture needle has the advantages of being simple in structure, convenient to operate, accurate in judging, small in damage and the like.

Description

V-P isocon abdominal end is put the pipe puncture needle

Technical field

This utility model relates to medical medical instruments field, and the V-P isocon abdominal end that is specifically related to a kind of usefulness that punctures is clinically put the pipe puncture needle.

Background technology

The hydrocephalic, the modus operandi of the most often using is ventriculo-peritoneal shunt (V-P bypass), after in the operation V-P isocon head end being inserted the ventricles of the brain, connecting split flow pump, isocon is caused the surgical operation steps such as abdominal skin otch through subcutaneous tunnel and successively finish, next step requirement dissociates the isocon abdominal end and inserts the abdominal cavity, sews up the incision and namely finishes operation; Tradition V-P isocon abdominal end is inserted adopt of abdominal cavity mode more and is opened the abdomen mode, exists operating time long, and wound is large, and incision of abdominal wall and the abdominal complications shortcoming more than relatively runs into obesity, patient that stomach wall is thicker, and operating difficulty is larger.

The utility model content

The purpose of this utility model is in order to address the above problem, and the modus operandi that traditional needs are opened abdomen changes the puncture mode into and the V-P isocon abdominal end that designs is put the pipe puncture needle.

V-P isocon abdominal end is put the pipe puncture needle, but mainly form by deviating from the sheath pipe with the puncture needle avulsion split of passivity inner core, passivity inner core head end circle is blunt, 1/4 place, top is provided with baffle plate, and Puncture needle sleeve is in passivity inner core baffle plate below, and the tip does not exceed the head end of passivity inner core, square set has spring on the baffle plate, the spring outer race has bolt, and the outer wall of bolt is provided with the inner core draw-in groove that is connected with nut and the buckle platform corresponding with baffle plate, and passivity inner core tail end is provided with jointing;

Above-mentioned V-P isocon abdominal end is put the pipe puncture needle, it is characterized in that passivity inner core and puncture needle are hollow structure;

Above-mentioned V-P isocon abdominal end is put the pipe puncture needle, it is characterized in that being provided with the rectangle side opening apart from passivity inner core head end 2mm place;

Above-mentioned V-P isocon abdominal end is put the pipe puncture needle, and the length that it is characterized in that the rectangle side opening is 3mm, and wide is 2mm;

Above-mentioned V-P isocon abdominal end is put the pipe puncture needle, it is characterized in that but the avulsion split deviates from the sheath pipe and be comprised of the semicanal of two symmetries with handle, semicanal adopts hard PVC material to form, and two semicanals connect by several dots structures, can delamination become two semicanals under the External Force Acting.

This utility model compared with prior art has simple in structure, easy to operate, accuracy of judgement, the damaging advantage such as little.

The specific embodiment

V-P isocon abdominal end is put the pipe puncture needle, main by the puncture needle 1 with the passivity inner core, but the avulsion split is deviate from sheath pipe 2 and is formed, passivity inner core 3 head ends circle is blunt, 1/4 place, top is provided with baffle plate 4, puncture needle 1 is placed in passivity inner core 3 baffle plates 4 belows, the most advanced and sophisticated head end that does not exceed passivity inner core 3, square set has spring 5 on the baffle plate 4, spring 5 outer race have bolt 6, the outer wall of bolt 6 is provided with the inner core draw-in groove 8 that is connected with nut 7 and the buckle platform 9 corresponding with baffle plate 4, and passivity inner core 3 tail ends are provided with jointing 10, and passivity inner core 3 and puncture needle 1 are hollow structure, 3 head end 2mm places are provided with long 3mm apart from the passivity inner core, the rectangle side opening 11 of wide 2mm; But the avulsion split is deviate from sheath pipe 2 and is comprised of the semicanal 13 of two symmetries with handle 12, and semicanal adopts hard PVC material to form, and two semicanals 13 connect by several dots structures 14, can delamination become two semicanals 13 under the External Force Acting.

During concrete operations, after finishing isocon ventricles of the brain end and putting pipe, insert the isocon position at abdominal part, cutting the long little otch of 1cm at skin is deep to subcutaneous, the isocon abdominal end is caused the abdominal cavity by hypodermic tunnel put the pipe position, mention stomach wall with towel clamp towel forceps from the otch two ends, at the cutting part vertical abdomen wall puncture of V-P isocon abdominal puncture needle, after puncture needle 1 is broken through stomach wall, because the resistance of abdominal wall tissue promotes, passivity inner core 3 ejects puncture needle 1 in the 5 lower very first times of effect of spring with limited length, thereby the effect of blocking is played at the tip of puncture needle 1 avoids puncture needle 1 tip to the damage of internal organs under the stomach wall, after puncture breaks through stomach wall, under passivity inner core 3 bullets, be connected with joint 10 with the 5ml syringe that is full of normal saline with syringe needle not, as seen normal saline enters the abdominal cavity under action of gravity, confirm that further puncture needle 1 has entered the abdominal cavity, pull out band inner core puncture needle 1, but sheath pipe 2 is deviate from the avulsion split to be kept somewhere in stomach wall, but the isocon abdominal end is deviate from sheath pipe 2 along the avulsion split insert the abdominal cavity, then the two handss handle 12 that pinches respectively both sides spurs to both sides, make two dots structure 14 complete ruptures between the semicanal 13, at this moment two semicanals 13 are separated fully and deviate from stomach wall, V-P isocon abdominal end is kept somewhere and intraperitoneal, sew up incision of abdominal wall, finish operation technique.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that produces does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
