Fig. 1-3 is please referred to, the utility model provides a kind of technical solution:

A kind of Medical orthopedic hammer, including hammer body 1, the first hammer handle 2 and percussion body 4, first hammer handle 2 are mounted on hammer body 1 side, the bottom for tapping body 4 and being mounted on hammer body 1, first hammer handle 2 is open-ended hollow tube, hollow at this It is equipped with the second hammer handle 3 in tube body, is being equipped with mounting hole 11, second hammer handle with the side of the relatively described hammer body 1 of the first hammer handle 2 3 install with the disassembly of mounting hole 11, and the top of the hammer body 1 offers interior hexagonal counterbore 10, offers on 4 side of percussion body Several groups counterweight tank 41 taps body 4 and hammers to steel nail.

One end of second hammer handle 3 is spiral head 30, and the other end is offering external screw thread 31 near its end, described 30 diameter of spiral head is less than hollow tube internal diameter, and is threadedly coupled with mounting hole 11, is equipped in the open end of the hollow tube The internal screw thread 20 being threadedly engaged with external screw thread 31, in this way when the second hammer handle 3 can be inserted into hollow tube by spiral head 30, And it can be cooperated by external screw thread 31 and internal screw thread 20 thus will by rotating the other end (i.e. exposed end portion) of the second hammer handle 3 Second hammer handle 3 and the first hammer handle 2 are fixed, are incorporated in the second hammer handle 3 in first hammer handle 2, convenient to need to use the Two hammer handles 3 are drawn off.

The bottom of the hammer body 1 offers tapped blind hole 12, and the percussion body 4 is equipped with and is threadedly coupled with tapped blind hole 12 Bolt 40, can quickly carry out that installation is fixed and disassembly to it.

The counterweight tank 41 is set as five groups, and activity is inserted with breeding block 6 in counterweight tank 41, and block 6 of breeding is by setting Tapping, the bandage 5 on 4 side of body is fixed, and 41 size of counterweight tank is set according to breeding 6 weight of block according to actual use situation, such as The breeding block 6 of 0.5Kg can be stored, i.e. percussion 4 weight of body can be incremented by it by quality standard of 500g by entirely tapping body 4 in this way Weight basis itself increases separately 0.5kg, 1kg, 1.5kg, 2kg, 2.5kg, can be needed conveniently according to different when in use Quickly increase the weight of hammer body 1, different patients or position tap that dynamics is different, improve patient to the good of the satisfaction of surgical instrument Good effect；For bandage 5 as shown in Figure 1, one end is fixed on counterweight tank 41 on one side, other end movable button is tapping body 4 to cover The opening of counterweight tank 41 is fixed to the block 6 that makes to breed.

The sleeve 100 with interior hexagonal counterbore is movably installed on the interior hexagonal counterbore 10, sleeve 100 and interior hexagonal are heavy 10 size of hole is different, can be greater than interior 10 size of hexagonal counterbore according to actual use situation or be less than interior 10 ruler of hexagonal counterbore It is very little, adapt to the nut of different size steel nails.

6 edge of breeding block be equipped with recess 60, recess 60 facilitate doctor's finger pinch take breeding block 6 be put into counterweight tank 41 Interior or taking-up.

It needs to be driven into steel nail completely in patient bone and cannot reach fine by tapping body 4 as shown in Fig. 2, working as Effect when, the second hammer handle 3 can be taken out from the first hammer handle 2, then keep it solid by spiral head 30 and the cooperation of mounting hole 11 It is scheduled on hammer body 1, then interior hexagonal counterbore 10 is inserted on steel nail nut, make entire orthopedic mallet as the spanner for twisting hexagonal (hexagon)nut It uses, is driven into steel nail in patient bone completely to realize, it is both practical and convenient.
