Detailed ways

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Fig. 1 to Fig. 12, it is the nail delivery system for ankle joint fusion surgery of the present invention, which includes a casing 1, a fixing casing 2, a plurality of discharging units 3 and a feeding device 4, and the casing has a cavity for accommodating the fixing casing 5. The fixed shell is detachably placed in the cavity, and a plurality of discharge unit accommodation chambers 6 are arranged side by side in the fixed shell, and the discharge units are placed in the discharge unit accommodation chambers one by one. Specifically, the discharge unit includes The storage hopper 7, the discharge hopper 8 and the rotary pulling mechanism 9 are arranged in sequence from top to bottom. Any storage hopper can store multiple fixing nails of the same specification in the same direction, that is, the same storage hopper can only store fixing nails of one specification. Different storage hoppers store the fixing nails of different specifications. In this way, in specific use, according to the specific conditions, the fixing nails of various specifications can be stored to meet different needs. The output hopper of this embodiment has the same size as the storage hopper outlet The nail inlets connected together can form a seamless connection with the storage hopper, without leakage, and the material receiving is accurate and reliable. At the same time, there is also a nail outlet through which the fixing nails can only pass one by one. In order to achieve this goal, this implementation The discharge hopper of the example is set as a tapered transition section 10 in the area between the nail inlet and the nail outlet, the large end of the tapered transition section can accommodate multiple fixing nails, and the small end can only accommodate one fixing nail. For example, the large end of the tapered transition section is set to: the length is the same as or slightly longer than the length of the fixing nail, and the width is much larger than the diameter of the fixing nail, while the small end is set to: the length is the same as or slightly longer than the fixing nail, The size of the width is almost the same as the diameter of the fixed nail; the rotary pulling mechanism of this embodiment includes a pulling shaft 11 arranged below the nail outlet, a pulling wheel 12 set on the pulling shaft and one end fixed on the pulling shaft. The driving motor 13, the outer circumference of the pulling wheel is evenly distributed with a plurality of pulling through grooves 14, the pulling through grooves are arc-shaped gaps that are adapted to the shape of the fixing nails, and the bottom of the fixing shell is provided with a discharge port 15 , the top of the discharge port is provided with a collection space 16 for receiving all the fixed nails from the rotating puller mechanism, and all the fixed nails are collected through the collection space. This embodiment also includes a feeding device, which includes a The conveyor belt 17 and the guide mechanism, the guide mechanism includes two guide plates 18 symmetrically arranged on the longitudinal sides of the conveyor belt, one end of the two guide plates is rotatably fixed below the cavity through the hinge 19, and the other end is adjustable through the telescopic mechanism 25 Fixed in the place ahead of the conveyor belt, the telescoping mechanism 25 can be an existing technology such as an air cylinder or an oil cylinder, so that the two guide plates and the conveying direction have a taper that is far smaller and near larger, guides the fixing nails entering the conveyor belt, and sends the fixing nails into the conveyor belt. The shell is on the discharge channel 20 provided at the output end of the conveyor belt, thereby realizing sorting and conveying.

The specific sorting process:

When the fixing nail falls into the arc-shaped gap under the action of gravity, the driving motor starts to drive the pulling shaft and the pulling wheel to rotate, and at the same time drives the fixing nail to rotate. When the rotation reaches a certain angle, the fixing nail slides out of the arc-shaped gap under the action of gravity Fall into the collection space to realize sorting.

Specific delivery process:

The fixed nails in the collection space come to the conveyor belt through the discharge port, and the movement of the conveyor belt drives the fixed nails to move together. While moving, the guiding mechanism starts to work, because the two guide plates are in the direction of the conveying direction. The taper is used to guide the fixing nails, and accurately send the fixing nails into the discharge channel, so as to realize the delivery.

In this embodiment, the specified fixing nails of different specifications can be sorted out through a plurality of discharging units, and then the selected fixing nails can be sent out one by one through the feeding device, realizing the automatic feeding of the fixing nails. Automated surgery laid the groundwork.

In order to reduce the impact force of the fixing nail falling down and reduce the damage to the fixing nail, a buffer channel 21 is provided between the nail outlet and the arc-shaped gap in this embodiment, and the buffer channel and the nail outlet form an angle of 20- The 80° setting can reduce the descending speed and protect the fixing nails. Even better, when the included angle is in the range of 30-60°, it can form a good protection for the fixing nails without affecting the free fall of the fixing nails.

In this embodiment, a protective cover 22 is provided at the entrance of the housing, a closure lock 23 is provided between the protective cover and the housing, and a handle 24 is provided on its outer surface to facilitate opening or closing operations.

In actual use, this embodiment can also be used as a storage and delivery system for knives that may be used in fusion surgery.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that it can be described in terms of form and Various changes may be made in the details without departing from the scope of the invention defined by the claims.
