Description
Technical field:
This utility model relates to medical apparatus and instruments, and the shape face guide rail that vertically punctures is lost in specifically a kind of head center of the arrival rate that can improve the intracerebral hematoma puncture and intubation.
Background technology:
As everyone knows, intracerebral hematoma puncture operation is neurosurgery operation commonly used, in the hypertensive cerebral hemorrhage patient, often adopt especially, the diagnosis of intracerebral hematoma is many to be finished by head CT, and transverse axis position CT image is main operation reference picture, behind definite hematoma puncture point, the most requirement puncture is perpendicular to median sagittal plane, but carry out the difficult control of free-hand puncture to center sagittal plane vertical direction, often cause the drainage tube position not good, influence drainage effect.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of body surface center sagittal line sign of utilizing is provided, by guiding, guarantee the vertical median sagittal plane of direction of free-hand cranium brain puncture, the shape face guide rail that vertically punctures is lost in the head center of improving the arrival rate of intracerebral hematoma puncture and intubation.
This utility model can reach by following measure:
The shape face guide rail that vertically punctures is lost in a kind of head center, it is characterized in that forming by head location-plate, horizontal guide rail and vertical guide rail, head location-plate middle part is provided with horizontal guide rail mating hole and dog screw, head location-plate two ends are provided with the sagittal line locating hole, horizontal guide rail and horizontal guide rail mating hole match to merge and are located by dog screw, horizontal guide rail is provided with vertical guide rail mating hole and dog screw, vertical guide rail and vertical guide rail mating hole match and merge by the dog screw location, and it is the guiding puncture groove that vertical guide rail is provided with open top.
Head location-plate in this utility model is curved with the inner surface that patient's head contacts, so that head location-plate good positioning effect.
Head location-plate and horizontal guide rail are 90 ° of cross-like in this utility model, to improve the locating effect of puncture needle, improve success rate of operation.
The top of the guiding puncture groove on this utility model vertical guide rail is semicircular arc, and to coincide with 14F conduit external diameter, puncture needle is close to the groove top when puncture, improve success rate of operation.
When this utility model uses, elder generation is labelling operation puncturing point and center sagittal line on patient skin, do center sagittal line vertical line through point of puncture, labelling vertical line and center sagittal line intersection point, routine operation is operated to the cortex point of puncture and exposes, ready, again head location-plate bottom center is aimed at above-mentioned vertical line and the intersection point that hits exactly sagittal line, and make the head location-plate pass through the sagittal line locating hole at two ends simultaneously, and by the fixing head location-plate of assistant, then horizontal guide rail is inserted in the horizontal guide rail mating hole and by dog screw and locate, vertical guide rail is inserted in the vertical guide rail mating hole on the horizontal guide rail, make the centrally aligned cortex point of puncture of the cambered top end of guiding puncture groove, by the dog screw location, brain is threaded a needle be adjacent to guiding puncture groove cambered top end inserting needle, have good positioning effect, the success rate of operation advantages of higher.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
As shown in drawings, the shape face guide rail that vertically punctures is lost in a kind of head center, it is characterized in that by head location-plate 1, horizontal guide rail 2 and vertical guide rail 3 are formed, head location-plate 1 middle part is provided with the adaptive and dog screw 4 of horizontal guide rail, head location-plate 1 two ends are provided with the sagittal line locating hole, head location-plate 1 is curved with the inner surface that patient's head contacts, so that head location-plate good positioning effect, horizontal guide rail 2 matches with the horizontal guide rail mating hole and merges by dog screw 4 location, head location-plate 1 is 90 ° of cross-like with horizontal guide rail 2, to improve the locating effect of puncture needle, improve success rate of operation, horizontal guide rail 2 is provided with vertical guide rail mating hole and dog screw 5, vertical guide rail 3 matches with the vertical guide rail mating hole and merges by dog screw 5 location, it is the guiding puncture groove that vertical guide rail 3 is provided with open top, the top semicircular in shape of guiding puncture groove, to coincide with 14F conduit external diameter, puncture needle is when puncture, be close to the groove top, improve success rate of operation, when this utility model uses, elder generation is labelling operation puncturing point and center sagittal line on patient skin, do center sagittal line vertical line through point of puncture, labelling vertical line and center sagittal line intersection point, routine operation is operated to the cortex point of puncture and exposes, ready, again head location-plate bottom center is aimed at above-mentioned vertical line and the intersection point that hits exactly sagittal line, and make the head location-plate pass through the sagittal line locating hole at two ends simultaneously, and by the fixing head location-plate of assistant, then horizontal guide rail is inserted in the horizontal guide rail mating hole and by dog screw and locate, vertical guide rail is inserted in the vertical guide rail mating hole on the horizontal guide rail, make the centrally aligned cortex point of puncture of the cambered top end of guiding puncture groove, locate by dog screw, brain is threaded a needle be adjacent to guiding puncture groove cambered top end inserting needle, have good positioning effect, the success rate of operation advantages of higher.
