Specific embodiment

The utility model is described in detail with reference to specific embodiment and Figure of description.

As depicted in figs. 1 and 2, hand-held medical mincer provided by the utility model, including inner cylinder 10 and outer barrel 20. The outer circumference surface of inner cylinder 10 is equipped with import 13, and one end is equipped with rocking handle 30, and the other end is equipped with the outer cover 11 for opening up delivery outlet.It rubs Part 40 is removably disposed in inner cylinder 10, and tooth assembly, rocking handle 30 and spiral shell are ground including helical worm, helical cut knife and spiral Revolve worm screw, helical cut knife or spiral grinding tooth assembly linkage.Outer barrel 20 is set on the outer circumference surface of inner cylinder 10.Wherein, spiral shell It is respectively shown in Fig. 5,6 and Fig. 7 to revolve worm screw, helical cut knife or spiral grinding tooth assembly.

The utility model can crush requirement, to determine to cut using helical worm, spiral according to soft tissue or the specific of cartilage Cutter or spiral grinding tooth assembly, these three crush strengths for rubbing part 40 step up, and granularity continuously decreases, therefore can meet The different demands of different application occasion, and rocking handle 30 can be carried out hand or be driven using motor as needed, it is easy to use.

As shown in Fig. 2, import 13 is equipped with clamping block 14, outer barrel and 14 corresponding position of clamping block close to one end of rocking handle 30 Equipped with bayonet 21.Using the structure of bayonet 21 and clamping block 14, outer barrel 20 covers import 13, and is remained fixed with inner cylinder 10, Will not occur sliding and crushed material being caused to splash out in crushing process.

As shown in Figure 3 and Figure 4, the inner end of rocking handle is equipped with socket 32, and the one end for rubbing part 40 is equipped with what is be adapted to socket 32 Pitching pile 41, a fixing piece 31 is inserted into along the vertical direction of the axis with socket 32 along socket 32, and is offseted fixation with pitching pile 41.It inserts Mouth 32 and pitching pile 41 keep plugged and fixed, and human hand, which can directly carry out replacing, rubs part 40, and fixed, easy to disassemble, also very square Just it cleans.

Delivery outlet is circumferentially evenly distributed, a diameter of 1mm, 2mm or 3mm.The diameter of different delivery outlets can meet not With the output demand of crushed material.

One end of inner cylinder 10 is equipped with inner cover 12, and inner cover 12 is equipped with the through-hole passed through for rocking handle 30.Inner cover 12 can carry The leakproofness of high inner cylinder 10, and convenient for rocking handle 30 is fixed and is limited.

Inner cover 12 and outer cover 11 are used with inner cylinder 10 to be screwed, and the mode easy disassembly being screwed facilitates conscientious It replaces and rubs part 40 and cleaned.

As shown in fig. 7, spiral grinding tooth assembly is included with the screw rod of grinding head 42 and grinding base 43, screw rod and rocking handle 30 Linkage, the inner wall of the excircle and inner cylinder 10 of grinding base 43 are fixed, and one end far from grinding head 42 is communicated with outer cover 11, are ground in seat Tooth lapping and the tooth lapping of 42 periphery of grinding head it is cross-shaped.The teeth directional of grinding head 42 and grinding base 43 interlocks so that grinding Efficiency is substantially improved.

As shown in Fig. 5,6 and Fig. 7, the cross section of socket 32 is triangle, and triangle is simplest polygon, compared to circle For shape, positioning action can be played, prevents that failure mode occurs between rubbing part 40 and rocking handle 30.

As shown in fig. 7, the internal cavity of grinding base 43 is in coniform, and grinding head 42 is stretched into cavity, and grinding head 42 Outer be made of lower concave segment peace straight section.Tissue or cartilage to be treated first have to enter the cavity in grinding base 43, and Lower concave segment can play the role of receiving so that the accommodating chamber that tissue or cartilage are continuously formed from lower concave segment enters 43 He of grinding base Gap before grinding head 42 carries out continuously grinding and final output.

The tooth socket of grinding head 42 is gradually deepened and is widened with the increase of its radius so that and graft can comparatively fast enter, But grinding precision reaches highest when reaching the head end of grinding head 42 so that the particle size reduction of graft to expection so that graft It can continuously be exported voluntarily.

The utility model be hand-held hand-rail type (can use electronic), hand low speed does not have Wen Sheng, using it is electronic when can Graft is cooled down, and blended using low speed in advance, tissue is notheated denaturation.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn that under the enlightenment of the utility model The structure change made, it is every that there is same or similar technical solution with the utility model, each fall within the guarantor of the utility model Within the scope of shield.
