A taper cover is fixed on the lower end mouth of the internal tube, internal tube through holes are arranged on the taper cover. External tube through holes are arranged on the lower end of the tube wall. Length scale is arranged on the external side wall of the external tube. A movable metal puncture needle is arranged between the external tube internal wall and the internal tube external wall. The utility model has no accurate position requirement; the utility model does not interfere with the CT image and damage the brain issue during the puncture operation.

Description

Improved bicavate cranium brain puncture irrigation and drainage pin

Affiliated technical field

This utility model relates to a kind of improved medical apparatus and instruments, is meant a kind of improved bicavate cranium brain puncture irrigation and drainage pin especially.

Background technology

At present, existing bicavate cranium brain puncture irrigation and drainage pin is metal, it in use exists the defective high to the positioning accuracy request of site of puncture, in case be positioned with deviation on skull, then must relocate on skull again, boring and puncture more again; And the outer tube lower ending opening of existing bicavate cranium brain puncture irrigation and drainage pin with the metal manufacturing is a straight-opening type, so it can carry out the destruction of cutting type to cerebral tissue in the puncture cerebral tissue arrives at the process of focus; In addition, the bicavate cranium brain puncture irrigation and drainage pin that metal is made can produce radial pseudo-shadow, the readability of serious image CT image on the CT image.

Summary of the invention

It is a kind of not high to positioning accuracy request, less and can not produce interferential improved bicavate cranium brain puncture irrigation and drainage pin to the CT image to brain tissue impairment in piercing process that the purpose of this utility model is to provide.

The purpose of this utility model is to realize like this, a kind of improved bicavate cranium brain puncture irrigation and drainage pin, comprise interior pipe, outer tube, interior pipe outlet connection and outer tube outlet connection, wherein the lower end tube wall of the interior pipe made from flexible nonmetal material links together with the lower end tube wall closure of the outer tube made from flexible nonmetal material; On the mouth of pipe of the lower end of interior pipe, be set with a cone-shaped hood, on cone-shaped hood, scatter and be provided with interior pipe through-hole; Pipe through-hole outside distribution is provided with on the tube wall of outer tube lower end; On the tube wall of the outside of outer tube, be provided with the length graduation mark; Activity is inserted with a metal puncture spicule between the outer wall of the inwall of outer tube and interior pipe.

Because pipe and outer tube are made with flexible nonmetal material in of the present utility model, its puncture rigidity is to be provided by the metal puncture spicule that activity is plugged in the outer tube tube chamber, can change the direction of puncture by the bending metals spicule that punctures during puncture, so when skull location and perforate have deviation slightly, only need readjust the degree of crook of metal puncture spicule, promptly can in same perforate, reach the purpose of revising deviation, thereby can alleviate infringement and misery patient; And, because the outer pipe through-hole and the interior pipe through-hole of this utility model leading section all are laterally disposed, and have set up the cone-shaped hood with good puncture effect in the end, so during with this utility model puncture cerebral tissue, only can produce penetrability and damage, and can not cause machinability to damage cerebral tissue; In addition, because this utility model can take out at the puncture metal puncture spicule of back in it that put in place, an only remaining interior pipe and an outer tube made from nonmetallic materials stayed intracranial, so it can not produce pseudo-shadow interference in the CT image.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described, a kind of improved bicavate cranium brain puncture irrigation and drainage pin, pipe 2, outer tube 6, interior pipe outlet connection 3 and outer tube outlet connection 5 in comprising, wherein the lower end tube wall of the interior pipe made from flexible nonmetal material 2 links together with the lower end tube wall closure of the outer tube made from flexible nonmetal material 6; On the mouth of pipe of the lower end of interior pipe 2, be set with a cone-shaped hood 9, pipe through-hole 1 in distribution is provided with on cone-shaped hood 9; The tapering point that cone-shaped hood 9 forms can improve puncture ability of the present utility model, is dispersed in interior pipe through-hole 1 on the cone-shaped hood 9 and the medicinal liquid in the interior pipe 2 can be scattered and be injected among the focus, and can form in a big way souring; Pipe through-hole 8 outside distribution is provided with on the tube wall of outer tube 6 lower ends; Be provided with length graduation mark 7 on the tube wall of the outside of outer tube 6, the doctor promptly can know clearly insertion depth of the present utility model by observing length graduation mark 7; Activity is inserted with a metal puncture spicule 4 between the outer wall of the inwall of outer tube 6 and interior pipe 2, metal puncture spicule 4 can equally support softish interior pipe 2 and outer tube 6 by the Os Elephatis frame, make it have certain rigidity and finish the puncture operation, promptly can change puncture direction of the present utility model by bending metals puncture spicule 4 simultaneously, thereby can revise deviations easily.

Can clearly explain concrete structure of the present utility model in order to make accompanying drawing, accompanying drawing has adopted the technique of painting of exaggeration, promptly fully proportionally do not draw, in fact the thickness and the soft or hard of the thickness of outer tube 6 and soft or hard and the tube for transfusion that uses when beating garter are similar, so behind the pipe 2, its last slit is very little in being provided with in outer tube 6, and this slit is used to derive the hematoma solute and uses, so in order to make it more unobstructed, interior pipe 2 can be to be arranged among the tube chamber of outer tube 6 in eccentric mode.

Flexible nonmetal material described in the utility model is meant plastics, carbon fiber and/or rubber; Other material with similar performance also can.

Using method of the present utility model is as follows:

A. the site of puncture perforate of on skull, determining with drill bit;

B. puncture meninges at tapping, then from the meninges breakage insert this utility model to cerebral tissue puncture make bottom of the present utility model arrive at focus after, extract metal puncture spicule 4, and this utility model is fixed in wrapping;

C., the syringe that liquefaction or hemostatic agent will be housed is plugged on the interior pipe outlet connection 3, an empty syringe is plugged on the outer tube outlet connection 5, inject medicament by interior pipe 2 to affected area on one side then, extract mixing material by outer tube 6 out from affected area on one side, carry out continuously being eliminated until hematoma;

D. carry out the CT check, if find that the position after the puncture of hematoma position and this utility model is not good, this utility model can be withdrawed from, then behind the degree of crook according to deviation size adjustment metal puncture spicule 4, again after from former perforate, puncturing, repeating step B; Clean out if find hematoma, then carry out follow-up routine operation.
