Abstract

The utility model relates to a bird brain solid locator, belonging to an instrument for the scientific experiment. The bird brain solid locator is composed of a microinjector (or a cutting knife frame), a micrometer head, a support frame, etc. The bird brain solid locator is characterized in that a monocular upright optical microscope for detaching an eye lens, an objective lens, a changeover panel, a light collector and an objective table is adopted to be served as a main frame. The propelling scales (4, 5, 6, 7) of the microscope are fixed on the bottom of the lens barrel via a mounting panel. The front edges of the propelling scales are fixed with a microinjector support frame (3) which can be used for fixing a micrometer head (1) and a microinjector (2), and moreover, the micrometer head and the microinjector are ensured being on a vertical line. A fixing frame (10) is provided with a right ear bar and a left ear bar (13) which are symmetrical and are used for fixing the outer ears of the experimental animal. Beak rods (11) are arranged on the beak rod moving slots (12) of the right side plate and the left side plate of the fixing frame. The bird brain solid locator has the advantages of simple structure, and accurate injection and cutting. The manufacturing cost is only 1/5 manufacturing cost of the stainless steel structure. The bird brain solid locator is suitable for the research in the general laboratory in China.

Description

Brain solid postioner

This utility model belongs to a kind of scientific experiments instrument.

Existing birds brain solid positioner is stepped on ［ Karten, D.J.and W. Hodos. (1967) A sterotaric Atlas of the Brain of the pigeon (Columba Livia) .Baltimore by card; Johns Hophins University Press.) ］ the rustless steel manufacturing is adopted in invention, though the accurate advantage in location is arranged, higher to the required precision of processing and fabricating, cost an arm and a leg, and inconvenient operation.

The purpose of this utility model is to utilize the accuracy of optical microscope, and a kind of improved birds brain solid positioner is provided, and accurately make simply the location, cheap, and multipurpose (cutting of brain location and locating injection) is flexible and convenient to use.

This utility model is finished as follows: with the upright optical microscope of a monotubular, unload eyepiece, object lens and changeover panel thereof, condenser and object stage, as the body frame of birds brain solid positioner, in the bottom of lens barrel the propelling chi is installed, advance microinjection apparatus or cutting knife are installed on the chi.Microinjection apparatus comprises microsyringe, micrometer head and support.Slowly accurately advance the nook closing member of microsyringe to reach the purpose of slow micro-injection with micrometer head.Can be according to the needs flexible conversion cutter sweep and the microinjection apparatus of cutting and injection.The one fixing device of laboratory animal (birds) head is installed on Microscope base.This device is provided with a movable beak rod, according to the size of laboratory animal, adjusts the position of beak rod, and guarantees the unchanged direction (being that external ear-bicker line becomes 45 ℃ of angles with horizontal plane) of head.

Below with reference to accompanying drawing this utility model is described in further detail.

Figure one is the side view of this utility model when being used for locating injection.

Figure two is this utility model side views when the cutting of location.

Among the figure one: the 1-micrometer head; The 2-microsyringe; 3-microsyringe support; The 4-left and right horizontal moves adjustable screw; Move horizontally adjustable screw before and after the 6-; Horizontal scale before and after the 7-; The vertical inserting needle spiral of 8-; The vertical inserting needle scale of 9-; The 10-fixed mount; 11-beak rod; The 12-beak bar moving slot; 13-ear rod; 14-ear rod fixed screw; The 17-operation window.

Among Fig. 2: the 5-left and right horizontal moves scale;

The 15-cutting knife;

The 16-cutting blade.

With reference to figure one, advance chi (comprising 4,5,6 and 7) to be fixed on the lens barrel bottom microscope by support plate.At the fixing microsyringe support (3) of the leading edge that advances chi, this support is micrometer head (1) and microsyringe (2) fixedly, and assurance micrometer head and microsyringe are on a vertical line.The nook closing member of microsyringe is with spring outward, sucks injection when being convenient to be rotated counterclockwise micrometer head.Two symmetrical ear rods (13) were used for fixing the laboratory animal external ear about fixed mount (10) was provided with, and beak rod (11) is arranged on the beak bar moving slot (12) of fixed mount left and right sides plate, and the extensions of this groove are by ear rod and 45 ℃ of angles of horizontal plane.Therefore can be according to the position of the size adjustment beak rod of laboratory animal, when the beak rod compressed the animal bicker, the position of brain and direction must be in fixing.Can position injection with reference to using the brain stereotaxic atlas both at home and abroad always by this orientation fixing head.

With reference to figure two, cutting knife (15) is fixed on the preceding beak of propelling chi, made the brain coronal section and bicker-external ear is wired to 45 ℃ of angles with this cutter sweep, can be carried out with reference to brain stereotaxic atlas commonly used both at home and abroad with the recognition that is brain section that benchmark is done of this coronal section.

This utility model system is converted by microscope, does not damage microscopical any parts.Therefore, when needs were observed section, also detachable optional feature down assembled the original parts of microscope and gets final product.So being particularly suitable for domestic common laboratory scientific research, uses this utility model.

Claims

1, a kind of birds brain solid positioner, by microsyringe (or cutting knife), composition such as micrometer head and support, it is characterized in that adopting and unload eyepiece, object lens, changeover panel, the upright optical microscope of the monotubular of condenser and object stage is a body frame, microscope advances chi (to comprise 4,5,6 and 7) be fixed on the lens barrel bottom by support plate, at the fixing microsyringe support (3) of the leading edge that advances chi, this support is micrometer head (1) and microsyringe (2) fixedly, and guarantee that micrometer head and microsyringe are on a vertical line, two symmetrical ear rods (13) were used for fixing the laboratory animal external ear about fixed mount (10) was provided with, and beak rod (11) is arranged on the beak bar moving slot (12) of fixed mount left and right sides plate.
