Description

A spiral cutter head mechanism

technical field

The utility model relates to the technical field of medical instruments, in particular to a spiral cutter head mechanism.

Background technique

When orthopedic surgeons obtain autologous bone during surgery, they need to remove soft tissues such as muscle and fascia on the bone surface. Most of them use a scalpel to remove the bone and flesh. This method is labor-intensive and inefficient.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a spiral cutter head mechanism with a reasonable structure and good peeling effect.

In order to achieve the above purpose, the technical solution provided by the utility model is: a spiral cutter head mechanism, which includes a bottom plate, a side plate, and a shovel seat. The bottom plate is rectangular, and the bottom of one end of the length direction is provided with an inclined guide , the higher end of the guide surface is located at the end of the bottom plate, two side plates are fixed on both sides of the top of the bottom plate in the length direction, the shovel seat is fixed at the other end of the bottom plate in the length direction, and the two sides of the shovel seat are connected and fixed with the corresponding side plates. The shovel seat on the side of the guide surface is inclined forward and downward to form a curved shovel surface. A knife shaft is movably hinged between the two side plates above the guide surface. One end of the knife shaft passes through the side plate and is connected to the motor. The surface of the knife shaft Spiral convex ribs are provided, concave-convex cutting edges are provided on the surface of the convex ribs, a shoveling passage is reserved between the cutting edge and the surface of the bottom plate, and the lowest part of the shovel surface extends into the shoveling passage.

The top of the side plate is inclined, and the higher end of the inclined surface is connected to the shovel seat, and the lower end of the inclined surface is arc-shaped and smoothly transitioned, and the cutter shaft is located between the two transition ends.

The cutter shaft, convex rib and cutting edge are integrally formed.

The bottom of the shovel surface and the surface of the bottom plate are sealed and connected, and the inner arc of the shovel surface is upward.

The top of the shovel base is provided with a concave collection chamber.

After the utility model adopts the above scheme, the guide surface is used to guide the advancing direction of the bottom plate, and at the same time reduce the resistance of the bottom plate to advance, the knife shaft is driven by the motor to rotate, and the meat fiber on the bone is peeled off through the convex rib and the cutting edge, and the bone is peeled off. The removed meat fibers are sent to the collection chamber of the shovel seat through the shovel channel and the shovel surface. The small front and large rear side plates are conducive to reducing the weight of the entire structure, and the smooth transition end can also effectively reduce the propulsion of the entire device. Resistance, after adopting this scheme, the structure is reasonable and the effect of peeling meat is good.

Detailed ways

Below in conjunction with all accompanying drawings the utility model is further described, the preferred embodiment of the utility model is: referring to accompanying drawing 1, a kind of spiral cutter head mechanism described in the present embodiment includes bottom plate 1, side plate 2, shovel Seat 3, the base plate 1 is rectangular, the bottom of one end in the length direction is provided with an inclined guide surface, the higher end of the guide surface is located at the end of the base plate 1, and the side plates 2 are two pieces, which are respectively fixed on both sides of the top of the base plate 1 in the length direction. The shovel seat 3 is fixed on the other end of the bottom plate 1 in the length direction. The top of the shovel seat 3 is provided with a concave collection chamber. The two sides of the shovel seat 3 are connected and fixed with the corresponding side plates 2. The shovel surface 4 extends obliquely below to form an arc surface. The bottom of the shovel surface 4 and the surface of the bottom plate 1 are sealed and connected, and the inner arc surface of the shovel surface 4 is upward, and the knife shaft is movably hinged between the two side plates 2 above the guide surface. 5. One end of the cutter shaft 5 passes through the side plate 2 and is connected to the motor. The top of the side plate 2 is inclined, and the higher end of the inclined surface is connected to the shovel seat 3. The shaft 5 is located between the two transition ends, the surface of the knife shaft 5 is provided with a spiral convex rib 6, and the surface of the convex rib 6 is provided with a concave-convex cutting edge 7, and the knife shaft 5, the convex rib 6, and the cutting edge 7 are integrally formed A shovel channel is reserved between the cutting edge 7 and the surface of the bottom plate 1, and the lowest point of the shovel surface 4 extends into the shovel channel. The guide surface of this embodiment is used to guide the advancing direction of the base plate, and at the same time reduce the resistance of the base plate to advance. The knife shaft is driven by the motor to rotate, and the meat fibers on the bone are stripped through the convex ribs and cutting edges, and the meat fibers after stripping The material is sent to the collection room of the shovel seat through the shovel channel and the shovel surface. The small front and large rear side plates are conducive to reducing the weight of the entire structure, and the smooth transition end can also effectively reduce the propulsion resistance of the entire device. Adopting this implementation The structure after the example is reasonable, and the peeling effect is good.
