Abstract
The utility model discloses a novel multifunctional microdissection knife comprising a needle, a barrel and a piston rod. The needle comprises a needle point and a needle guard integrated with the needle point, a 150-degree inclination angle is formed between the needle point and the needle guard, two corresponding protruding tenons are arranged inside the needle guard, the needle sleeves a mouth head at the front end of the barrel, tenon grooves corresponding to the protruding tenons in position are formed in the outer wall of the mouth head, and the bottom of a plastic rod body of the piston rod is wrapped with a rubber piston closely attached to the wall of the barrel. The needle is made of high-carbon steel, so that bending and inclination angle change are avoided; the needle can be prevented from rotation since the tenons are fixed; dissection experiments can be carried out conveniently since the needle point and the needle guard are designed with the inclination angle; in addition the needle can be changed into a common syringe needle to complete histocyte extraction so as to bring convenience to experimenters.
Description
Technical field
This utility model relates to biotechnology research experiment technique with the apparatus field, relates in particular to the micro-separation dissecting knife of a kind of Multifunction.
Background technology
The research fields such as modern biomedical, animal medicine, herding, clinical medicine, great majority are all using mice as object of study, the a lot of situations of separation of the embryonal tissue of mice all will operate under the microscope, but common ophthalmology separation cutter cannot be realized the object of anatomical isolation at all, and normal anatomy also needs to adopt in addition syringe to extract histiocyte later, seems cumbersome.
Utility model content
(1) technical problem that will solve
For addressing the above problem, the utility model proposes the micro-separation dissecting knife of a kind of Multifunction, it not only can carry out the dissection of experiment mouse very easily, syringe needle both can be used for extracting histiocyte with changing ordinary syringe syringe needle into simultaneously.
(2) technical scheme
The micro-separation dissecting knife of this Multifunction, it comprises syringe needle, cylindrical shell and piston rod, it is characterized in that: described syringe needle comprises needle point and the needle guard with needle point one, described needle guard inside is provided with two corresponding protruding tenons, described syringe needle is placed on the mouth of barrel front end, the outer wall of described mouth is provided with the tenon groove corresponding with a described protruding falcon position, and described piston rod plastics body of rod bottom is enclosed with the rubber piston fitting tightly with barrel wall.
Further, described needle point diameter is 0.3-0.4mm, and needle point and needle guard are 150 ° of angles of inclination, and needle point is solid rod-like, and described needle point top is provided with declivous cutting edge.
Further, described cylindrical shell length is 13cm-15cm.
Further, described syringe needle entirety is that high-carbon steel is made.
(3) beneficial effect
It has following beneficial effect this utility model: this utility model Multifunctional display differential improves according to 1ml syringe from dissecting knife, syringe length has lengthened person easy to use and has held, syringe needle adopts high-carbon steel made, good rigidly, there will not be buckling phenomenon, needle point and syringe entirety are 150 ° of inclinations, conveniently dissect, syringe needle is connected with the tenon that syringe is provided with cooperation, there will not be rotation phenomenon, when dissected is more stable, and needle head replacing is that ordinary syringe syringe needle both can complete histiocytic extraction work by the pull of piston rod later.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-syringe needle; 2-cylindrical shell; 3-piston rod; 11-needle point; 12-needle guard; 21-mouth; 31-rubber piston; 121-projection tenon; 211-tenon groove.
The specific embodiment
The micro-separation dissecting knife of a kind of Multifunction as shown in Figure 1, it comprises syringe needle (1), cylindrical shell (2) and piston rod (3), described syringe needle (1) comprises needle point (11) and the needle guard (12) with needle point one, described needle guard (12) inside is provided with two corresponding protruding tenons (121), described syringe needle (1) is placed on the mouth (21) of cylindrical shell (2) front end, the outer wall of described mouth (21) is provided with the tenon groove (211) corresponding with described protruding falcon head (121) position, described piston rod (3) plastics body of rod bottom is enclosed with the rubber piston (31) fitting tightly with barrel wall.
Wherein, described needle point (11) diameter is 0.3-0.4mm, and needle point (11) is 150 ° of angles of inclination with needle guard (12), and needle point (11) is solid rod-like, and described needle point (11) top is provided with declivous cutting edge; Described cylindrical shell (2) length is 13cm-15cm; Described syringe needle (1) entirety is that high-carbon steel is made.
This utility model Multifunctional display differential improves according to 1ml syringe from dissecting knife, be provided with the made syringe needle of high-carbon steel as the cutlery of dissecting, needle point with hold syringe and be 150 ° of inclinations, conveniently dissect, syringe needle and syringe adopt fixing tenon to fix, there will not be rotation, the relative 1ml syringe of syringe has lengthened, and handled easily person hold, and syringe needle can be replaced with ordinary syringe syringe needle and carries out histiocytic extraction in addition, be at one stroke dual-purpose, brought convenience to experimenter.
Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of this utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents of this utility model request protection, has all been documented in claims.
