Description

Technical Field

[0001] The utility model belongs to a medical bone crushing instrument, in particular to a bone crushing forceps. Background Art

[0002] Bone crushing technology is a technique that needs to be applied in many surgeries. It mainly involves crushing bones and then stuffing them back together, which is called bone crushing backfilling. The purpose of bone crushing backfilling is to, on the one hand, form bone induction, inducing the adjacent tissues to secrete collagen through some components in the bone, accelerating bone healing; on the other hand, form bone conduction, and the crushed bones provide a scaffold for bone healing, allowing bone tissue to crawl and replace, making it heal faster. The more broken the bones are, the more conducive it is to play the above roles.

[0003] The existing method of bone crushing is to use bone crushing forceps, whose structural design and operating principle are similar to scissors. In essence, it is a manual "cutting and breaking" method, so it is impossible to break the bones into an ideal state, and only one bone can be cut and broken at a time. It takes multiple operations to bite and break, which is inefficient. In addition, because bones are very hard, the existing operation method of similar bone crushing forceps is very laborious, and smaller bones need to be scissors held by hand. Medical staff are prone to rubbing the skin on their hands during operation, and even the flesh on their hands is bitten off by the bone crushing forceps, which makes medical staff very easy to get injured. Moreover, the existing bone crushing forceps are operated by fingers. Medical staff who use this type of bone crushing forceps for a long time are prone to excessive strain on the fingers and wrist joints, causing tenosynovitis and damaging their health.

[0022] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides a bone crushing forceps, comprising a supporting component, a hammer tail, a hammer head component, a force transmission component and a pressing component; wherein:

[0024] The support assembly includes a base, a bracket arranged parallel to the base, and a force transmission assembly is arranged on the bracket;

[0025] One end of the hammer tail is held by the operator, who applies force to the hammer tail;

[0026] The hammer assembly includes a hammer arm and a hammer barrel, one end of the hammer arm is fixed to the side wall of the hammer barrel, and the other end is fixed to the bracket through a force transmission assembly and connected to the other end of the hammer tail, and the force is transmitted to the hammer barrel through the hammer arm;

[0027] The pressing assembly comprises an upper grinding disc arranged at the bottom of the hammer head barrel, and a grinding bowl placed on the base, wherein the grinding bowl is located directly below the upper grinding disc.

[0028] The utility model can isolate the operator from the bone crushing area by arranging the hammer head arm, and the structural design of the hammer tail is convenient for medical personnel to hold and apply force with the palm, which is different from the conventional finger clamping method and is not easy to cause injuries to the fingers and wrists. Moreover, the bone crushing area is far away from the operator, so the force application effect is good, the bone crushing effect is good and the safety is high.

[0029] Embodiment 1

[0030] like Figures 1 to 3 The bone crushing forceps shown include a supporting component and a pressing component.

[0031] The support assembly includes a support base 001, a hammer assembly and a hammer tail 003. Two support seats 002 are provided in the middle of the support base 001 to form a bracket for installing the force transmission assembly. The support seats 002 are respectively connected to the hammer assembly and the hammer tail 003. The hammer assembly includes a hammer arm 004 and a hammer barrel 005. The hammer arm 004 includes a hammer main arm and a hammer auxiliary arm, both of which are horizontal columnar structures and are connected to the hammer barrel 005. The hammer tail 003 is provided with a handle for easy gripping. The hammer tail 003 and the hammer main arm, as well as the hammer main arm and the hammer auxiliary arm are connected through a gear structure to transmit the force.

[0032] The pressing assembly is divided into an upper grinding part and a lower grinding part. The upper grinding part is composed of a grinding rod and an upper grinding disc 0062. The grinding rod is fixed to the hammer barrel 005. That is, the grinding rod includes a grinding rod body (not shown in the figure) that passes through the hammer barrel and a rotating block 0061 located at the top of the grinding rod body. The rotating block 0061 is provided with a pair of holding rods 0065 parallel to the base. The upper grinding disc 0062 is installed at the end of the grinding rod body. The rotating block 0061 is provided with slots. The holding rod 0065 is at Figure 3 As shown in the figure, the rotation of the rotating block 0061 can be manually realized by holding the rod 0065, and the rotation angle can be set by the slot structure, such as 90° rotation, to achieve a better grinding effect. The lower grinding part is composed of a grinding bowl 0063 and a lower grinding disc 0064. The lower grinding part is fixed on the support base 001. The grinding bowl 0063 plays the role of placing the bone block to prevent the bone block from splashing when pressing.

[0033] The contact surfaces of the upper grinding disc 0061 and the lower grinding disc 0062 are both set to a triangular needle-shaped structure, and can be fixed and disassembled by screws to facilitate postoperative cleaning. The grinding bowl 0063 serves to place bone blocks to prevent bone blocks from splashing during pressing.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
