Abstract
The utility model discloses a manually -operated on cranium drill bushing spare, including an axostylus axostyle, the pilot pin of connection tip under the axostylus axostyle to and cup joint the drill bit on the axostylus axostyle, light -case bore a section of thick bamboo to the drill bit and a body coupling has the brill tooth in the drillstock that bores section of thick bamboo upper portion, the lower tip shaping of boring a section of thick bamboo including annular, and the shaping has and rotates the through -hole of being connected with the axostylus axostyle cooperation in the middle of the drillstock. Axostylus axostyle, drill bit are respectively by stainless steel integrated into one piece, and axostylus axostyle upper end shaping has a handle, cup joint one on the axostylus axostyle and are used for the drill bit spring on top downwards, and the both ends of spring are fixedly connected with magnet respectively, fixes through the magnetic force actuation between magnet and drill bit, the handle. Fix through the pilot pin and treat the drilling position on the skull, only need on the other hand fixed axostylus axostyle, another hand rotates the drill bit, can bore on the skull and open a round hole. Because the experimental animals skull is thinner, only need rotate a plurality of circles of drill bit and can bore the skull, rapid operation and dynamics are easily controlled.
Description
Technical field
This utility model belongs to medical instruments field, the manual drill for craniotomy external member used when being specifically related to a kind of medical experiment.
Background technology
Current use laboratory animal generally needs to use electric drill to bore on laboratory animal skull and opens a hole when carrying out brain related experiment, because laboratory animal (experimental mouse, experimental rabbit etc.) skull is thinner, dynamics bad grasp when using electric drill to punch, firmly during deficiency, drill bit easily skids, firmly spend after then drill bit breaks through skull more and easily insert in cerebral tissue, make laboratory animal directly dead, impact experiment is carried out smoothly.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of structure simple, can punch easily, be beneficial to the manual drill for craniotomy external member that experiment is carried out smoothly on laboratory animal skull.
For realizing the object of this utility model, be achieved by the following technical solutions: a kind of manual drill for craniotomy external member, includes an axostylus axostyle, be connected to the positioning needle of axostylus axostyle bottom, and be socketed in the drill bit on axostylus axostyle; Described drill bit includes the drilling pipe of an annular thin wall and is integrally connected to the drillstock on drilling pipe top, and the bottom of drilling pipe forms brill tooth, and drillstock intermediary form has the through hole coordinating with axostylus axostyle and be rotationally connected.
Preferably: described axostylus axostyle, drill bit are one-body molded by rustless steel respectively, axostylus axostyle upper end forms a handles, shaft rod upper sleeve is connected to a spring in order to be pushed up by drill bit downwards, and the two ends of spring are fixedly connected with Magnet respectively, is fixed between Magnet and drill bit, handle by magnetic attraction.
Preferably: the drillstock outer wall of described drill bit is circumferentially evenly connected with multiple outer raised line.
Preferably: described positioning needle is threaded connection the bottom at axostylus axostyle.
Compared with prior art, the beneficial effects of the utility model are: be fixed on position hole to be drilled on skull by positioning needle, and only need fixed axostyle on the other hand, another hands rotary drill bit, can bore and open a circular hole on skull.Because laboratory animal skull is thinner, only need the some circles of rotary drill bit to bore skull, rapid operation and dynamics are easy to control.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
embodiment 1
As shown in Figures 1 to 4, the present embodiment is a kind of manual drill for craniotomy external member, includes an axostylus axostyle 1, is connected to the positioning needle 4 of axostylus axostyle bottom, and is socketed in the drill bit 3 on axostylus axostyle; Described drill bit includes the drilling pipe 31 of an annular thin wall and is integrally connected to the drillstock 32 on drilling pipe top, and the bottom of drilling pipe forms bores tooth 311, and drillstock intermediary form has the through hole coordinating with axostylus axostyle and be rotationally connected; The drillstock outer wall of described drill bit is circumferentially evenly connected with multiple outer raised line 33.
Described axostylus axostyle, drill bit are one-body molded by rustless steel respectively, axostylus axostyle upper end forms a handles 11, shaft rod upper sleeve is connected to a spring 2 in order to be pushed up by drill bit downwards, and the two ends of spring are fixedly connected with Magnet respectively, is fixed between Magnet and drill bit, handle by magnetic attraction.Magnet comprises the upper Magnet 21 being connected to spring upper end and the lower magnet 22 being connected to lower spring end.
Described positioning needle is threaded connection the bottom at axostylus axostyle.
During use, positioning needle is inserted into position to be punctured, drill bit is pressed on skull under spring pressure effect, and only need fixed axostyle on the other hand, another hands rotary drill bit, can cut a circular hole on skull.
Described drill bit can be furnished with multiple size (namely the bore of drilling pipe is different), so that get out the opening of different size as required.
Claims (4)
