Abstract

An abdominal cavity catheter puncture needle comprises a needle tubing, a rod core and an outer catheter. The front end of the outer catheter is fixedly connected with the rear end of the needle tubing. The front end of the needle tubing is a slant surface, a hollow rod core is arranged inside the needle tubing, the outer end of the rod core is a blunt head and a needle tubing end head is exposed from the blunt head, and a side of the exposed part is provided with an open pore. The other end of the rod core is fixedly connected with an inner catheter, an inner nut, and a spring and a compression screw are arranged between the outer catheter and the inner catheter. A sleeve catheter is further arranged outside the needle tubing, the internal diameter of the sleeve catheter is slightly bigger than the external diameter of the needle tubing, the sleeve catheter can slide on the needle tubing, and the sleeve catheter is shorter than the needle tubing. According to the abdominal cavity catheter puncture needle, the abdominal cavity catheter intubation surgery does not need to perform an operation and can be finished by direct puncture. Therefore, the abdominal cavity catheter puncture needle has the advantages of minimal invasion, in addition, the abdominal cavity catheter puncture needle does not need to open abdomen, and to look steadily at a lower-disposed catheter.

Description

The abdominal cavity conduit puncture needle

Technical field

This utility model relates to a kind of surgical operating instrument, particularly the abdominal cavity conduit puncture needle.

Background technology

Hydrocephalus is common, the multiple disease of present neurosurgery, and ventriculoperitoneal shunt has become its standard care art formula.At present neurosurgeon is main to the selection of ventricles of the brain end point of puncture with cornu frontale ventriculi lateralis and cornu occipitale, and puncture technique is ripe, also has certain difficulty but insert at the drainage tube of abdominal end, must possess certain general outer basis.Traditional operation mode ventricles of the brain abdominal end is that the side hits exactly or the other 3cm otch of doing of lower abdomen rectus abdominis m. under right xiphoid-process, under direct-view, inserts, and need open abdomen, and is relatively complicated, has intestinal to stick company, incisional hernia etc. and opens abdomen common complication generation possibility.In recent years; Also have to be reported in a large number and insert ventricles of the brain abdominal cavity pipe under laparoscopically the assisting, the advantage that has Wicresoft, need not open abdomen, look at the underlying pipe straight, this technology need under the doctor who grasps laparoscopic technique help, be accomplished; Expense is big, is difficult for carrying out at basic hospital.。

Summary of the invention

The purpose of this utility model is to provide the abdominal cavity conduit puncture needle, to remedy the deficiency of prior art.

The purpose of this utility model is achieved in that the abdominal cavity conduit puncture needle, comprises needle tubing, excellent core, outer tube, and the outer tube front end is fixedly connected with the needle tubing tail end; The needle tubing front end is the inclined-plane, and the hollow bar core is housed in the pipe, and excellent core outer end is blunt nosed and exposes the needle tubing termination; There is perforate the exposed portions serve side, and pipe in the other end of excellent core is fixedly connected is provided with inner nut, spring and clamping screw between outer tube and the interior pipe; Outside needle tubing, also has sleeve pipe; Casing inner diameter is slightly larger than the needle tubing external diameter, and sleeve pipe can slide on needle tubing, and sleeve pipe is shorter than needle tubing.

As preferably, the sleeve pipe front end is the inclined-plane.

Through implementing this utility model, make abdominal cavity intubation catheter operation need not to operate on, directly puncture is accomplished, the advantage that has Wicresoft, need not open abdomen, look at the underlying pipe straight.

This utility model is further described through embodiment below in conjunction with accompanying drawing.

1 is excellent core among the figure, the 2nd, and perforate, the 3rd, needle tubing, the 4th, sleeve pipe, the 5th, outer tube, the 6th, spring, the 7th, interior pipe, the 8th, air pipe interface, the 9th, clamping screw.

The specific embodiment

The abdominal cavity conduit puncture needle comprises needle tubing 3, excellent core 1, outer tube 5, and the front end of outer tube 5 is fixedly connected with the tail end of needle tubing 3; The front end of needle tubing 3 is the inclined-plane, and hollow excellent core 1 is housed in the pipe, and the outer end of excellent core 1 is blunt nosed and exposes needle tubing 3 terminations; There is perforate 2 the exposed portions serve side, and pipe 7 in the other end of excellent core 1 is fixedly connected is provided with inner nut, spring 6 and clamping screw 9 between outer tube 5 and the interior pipe 7; Interior pipe 7 tail ends have air pipe interface 8, outside needle tubing 3, also have sleeve pipe 4, and the internal diameter of sleeve pipe 4 is slightly larger than the external diameter of needle tubing 3; Sleeve pipe 4 can slide on needle tubing 3, and sleeve pipe 4 is shorter than needle tubing 3, and sleeve pipe 4 front ends are the inclined-plane.

During use, be connected with the carbon dioxide carrier pipe at air pipe interface 8, with excellent core 1 blunt nosed contact skin of abdomen, suitably firmly thorn is pressed; Rod core 1 blunt nosed pressurized retraction needle tubing 3, while holddown spring 6, meanwhile, into abdominal part is pricked on the front end inclined-plane of needle tubing 3; Sleeve pipe 4 also gets into abdominal part in company with needle tubing 3, and behind needle tubing 3 entering abdominal cavities, the blunt nosed of excellent core 1 exposes needle tubing 1 automatically with the resilience of spring 6, and carbon dioxide is through the perforate 2 entering abdominal cavities of excellent core 1; After gas reaches requirement, extract needle tubing 3, stay sleeve pipe 4; From sleeve pipe 4 insertion abdominal cavities, extract drainage catheter out sleeve pipe 4 then, accomplish the abdominal cavity of drainage catheter and insert.
