Abstract

The invention relates to a shunt pipe enterocoelia end implant device, comprising a sleeve and a puncture needle, wherein the sleeve is internally provided with a blunt stylet or a sharp-pointed puncture needle. By using the implant device, the abdominal incision of a patient can be reduced to 0.5cm from 6-8cm in a traditional surgery, thus reducing the injury surface of the patient, relieving pain for the patient and speeding up the incision healing. When the implant device is used, the operation can be simple, safe and reliable, and the operation time is shortened to be no more than 5min from 20min in the traditional surgery, thus improving the operation efficiency; the operation which is finished by requiring the cooperation of two people or even more currently can be finished easily by one surgeon independently, thus lowering the labor cost; and the sleeve structure design is reasonable, thus facilitating the sleeve structure to be separated from the shunt pipe.

Description

Shunt pipe enterocoelia end implant device

Technical field

The invention belongs to medical instruments field, relate to a kind of shunt pipe enterocoelia end implant device.

Background technology

At present, in the operation of the clinical implementation ventricles of the brain one peritoneal shunt or other similar shunt operation processes, when the abdominal end of isocon is inserted this step of intraperitoneal, usually need two doctors to cooperate, after six layers of structure such as sheath behind skin, subcutaneous fat, theca of rectus abdominis muscle, rectus abdominis m., the rectus abdominis m., peritoneum are cut in layering, the isocon abdominal end could be inserted the abdominal cavity, and then sew up said structure respectively, also need nurse's positive cooperation; Need 20 minutes as this step 1, if patients abdomen fat is more, required time also can be longer, and the patients abdomen otch is about 6-8cm, damages bigger.

Summary of the invention

The object of the present invention is to provide a kind of shunt pipe enterocoelia end implant device, be convenient to operation, simple and efficient, otch is Wicresoft more, and is safe and reliable, and the operation cost is low.

The technical solution used in the present invention:

The positive beneficial effect that the present invention had:

1. adopt embedded devices such as sleeve pipe, blunt nosed nook closing member, tip puncture needle, the abdominal incision that makes patient is reduced into 0.5cm by the 6-8cm of traditional art, and patient's damage surface is very little, Wicresoft more alleviates patient's misery of performing the operation greatly, and wound healing is fast, insert effectively, meet the theory of minimally invasive surgery;

2. use this embedded device to make operation technique easy, quick, safe and reliable, operating time foreshortens to from 20 minutes of traditional art and is no more than 5 minutes, improves operation efficient greatly;

3. use this embedded device to improve the operation technique program that the isocon abdominal end is inserted the abdominal cavity, make present needs two people even many people cooperate the operation of finishing, by operative doctor one people just can be independently light complete operation, reduce the cost of labor of operation greatly;

4. sleeve pipe is two semi-circular opposite openeds, and is simple in structure, reasonable in design, unscrews screw sleeve pipe is separated with isocon easily.

The specific embodiment

With reference to Fig. 1, Fig. 2, shown in Figure 3, a kind of shunt pipe enterocoelia end implant device mainly comprises sleeve pipe 1, blunt nosed nook closing member 2, protection card 3, tip puncture needle 4 etc.; Its sleeve pipe 1 be two semi-circular can be to the elongate cavity pipe of folding, both internal diameters equate, external diameter does not wait, the external diameter of one of them is greater than another external diameter, and be provided with the bound edge 101 that is about 3mm, be that the big cavity pipe of external diameter contains the little cavity pipe of external diameter after both are involutory, each contains about 3mm both sides; Can place blunt nosed nook closing member 2 or tip puncture needle 4 in the cavity of sleeve pipe 1, the about 3mm in sleeve pipe 1 top is stretched out at the top of general blunt nosed nook closing member 2 or tip puncture needle 4; Described blunt nosed nook closing member 2 is a solid slim stock, and the bottom is provided with semi-circular handle 201, is against the effect that sleeve pipe 1 end can play stop bit when blunt nosed nook closing member 2 inserts sleeve pipe 1 back handle 201; Described tip puncture needle 4 is a solid slim stock, and the bottom is provided with semi-circular handle 401.

With reference to shown in Figure 4, described tip puncture needle 4 also can be a hollow thin stock, and the bottom is provided with pintle 403, can external syringe; The top 402 of tip puncture needle 4 is oblique tip type, and angle of inclination a is 15-30 °, the lumbar puncture needle of the present clinical use of its similar.

With reference to shown in Figure 5, described blunt nosed nook closing member 2 tops 202 are pyramid type, and its cone angle is 30-45 °, and needle point is the garden arcuation slightly.

With reference to shown in Figure 6, described tip puncture needle 4 tops 402 are oblique tip type, and angle of inclination a is 15-30 °.

With reference to shown in Figure 7, described sleeve pipe 1 outer wall is provided with protection card 3, and protection card 3 can slide up and down the degree of depth of regulating puncture along sleeve pipe 1 outer wall, and by screw blunt nosed nook closing member 2 or tip puncture needle 4 is locked, and protection card 3 is selected prior art clamping hoop type, buyable for use.

With reference to shown in Figure 8, described protection card 3 also can be bite type, is enclosed within sleeve pipe 1 outer wall and slides up and down the location, and is fastening by screw.

Sleeve pipe 1 of the present invention, blunt nosed nook closing member 2, tip puncture needle 4 are metal or duroplasts material, and its length, diameter can be made the tandem product of different specification size according to the human body site of puncture.

Use embedded device of the present invention to implement the operating procedure of ventriculo-peritoneal shunt operation:

1. the otch that abdominal incision one 0.5cm is long is adjusted protection card 3 positions on the sleeve pipe 1 according to the fat thickness of patients abdomen, and blunt nosed nook closing member 2 is inserted steel sleeve pipes 1, and vertically puncture makes blunt nosed nook closing member 2 enter the extraperitoneal space crack together with localized sleeve pipe 1 then;

2. extract blunt nosed nook closing member 2, pintle 403 external syringes with tip puncture needle 4, contain an amount of normal saline in the syringe, send into gently along sleeve pipe 1, cut peritoneums by the oblique tips in top 402, enter the abdominal cavity, can the phenomenon that normal saline in the syringe is inhaled into the abdominal cavity occur this moment because of the intraperitoneal negative pressure, for preventing to damage abdominal viscera, stop inserting needle; Extract tip puncture needle 4, insert again and extract after blunt nosed nook closing member 2 enlarges the peritoneum opening;

3. the isocon abdominal end is inserted the abdominal cavity from sleeve pipe 1 top, can soak into tube chamber by normal saline in case of necessity;

4. extract sleeve pipe 1, the separable characteristic of utilizing sleeve pipe 1 to split is separated with isocon, and skin incisions takes the circumstances into consideration to sew up the 1-2 pin, and operation finishes.
