Description

Elbow bone hook

Technical Field

The utility model relates to the technical field of surgical instruments, in particular to an elbow bone hook.

Background

Fractures are classified into stable fractures and surgical fractures; bone hooks are common surgical tools in surgical fractures, and function to pull the fractured bone for reduction. At present, the bone hook structure is different in size and comprises a holding shaft, one end of the holding shaft is a hook body which is bent, and the other end of the holding shaft is a holding part, which is described in the texts of Chinese patent publication No. CN216603048U named as an orthopedic clinical hook and the like. When in use, an operator holds the holding part, the hook body is hooked on the broken bone, the broken bone is pulled to a required direction for reduction, and then the subsequent operation is carried out. The bone hook is simple in structure and use mode, and can cope with normal fracture operation; however, when the fracture degree is severe and the fracture fit degree is high, stable fit points and larger pulling force are often needed to realize fracture pulling, so that the phenomenon that a relatively thin hook body cannot be reset due to excessive deformation of a hook body or a hook head is easily caused, and even the hook head is likely to be directly broken is likely to occur. For such cases, only the new bone hook can be replaced on site and reused; even if the hook body is slightly deformed, the whole bone hook must be discarded as medical waste in the later period so as to avoid influencing the actual use and intangibly causing medical waste. At present, how to maximally utilize the residual value of the current instrument, reduce medical waste and medical operation cost, and have been limited by more and more current standards of hospitals; then, it is considered to develop a continuous use effect of the bone hook by replacing the hook head when the hook head is deformed or even damaged and cannot be used continuously. In addition, clinical operation conditions suddenly change, the function of the existing bone hook is single, the hook head of one type is only suitable for one use condition, and whether the hook head of the corresponding type can be adaptively replaced according to different field operation conditions so as to enlarge the applicable occasion of a single bone hook is also a technical problem to be solved in recent years.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Specific implementations of the utility model are described in detail below in connection with specific embodiments.

Referring to fig. 1 to 3, an elbow bone hook according to an embodiment of the present utility model includes:

a handle 1;

a hook body 2;

the connecting assembly 3, the connecting assembly 3 includes a fixed cylinder 31, a connecting block 32, a fixture 33, and a first spring 34. The fixed cylinder 31 is installed on the end face of the handle 1, and the connecting block 32 is connected with the hook body 2. The inside of the connecting block 32 is provided with a guide hole 321, a clamping block 33 is arranged in the guide hole 321, a first spring 34 is connected between the two groups of clamping blocks 33, and two sides of the fixed cylinder 31 are provided with operation holes matched with the clamping blocks 33;

the first spring 34 is compressed by pressing the block 33 on the side wall of the connection block 32 into the guide hole 321, and then the connection block 32 on the hook body 2 can be inserted into the fixing cylinder 31. When the connecting block 32 slides in the fixed cylinder 31, the clamping block 33 and the operation Kong Xiangji on the side wall of the fixed cylinder 31 are normally operated, the first spring 34 ejects the clamping block 33, and the connecting block 32 is clamped in the fixed cylinder 31 through the operation hole, so that the hook body 2 and the handle 1 can be quickly connected. The clamping block 33 is pressed back into the guide hole 321 and is separated from the operation hole on the fixed barrel 31, and at the moment, the connecting block 32 can be taken out from the fixed barrel 31 again, so that the hook body 2 can be quickly installed, the hook body 2 can be quickly disassembled, and the hook body 2 can be conveniently maintained and replaced. Of course, the precision of the fit between the fixture block 33 and the guide hole 321 and the operation hole needs to be ensured to ensure the stability of use.

In the embodiment of the present utility model, referring to fig. 3, the flicking assembly 4 includes a flick block 41 and a second spring 42, the flick block 41 is slidably connected to the inner side wall of the fixed cylinder 31, and the second spring 42 is connected between the flick block 41 and the bottom surface of the fixed cylinder 31. When the connection block 32 is inserted into the fixed cylinder 31 to mount the hook body 2, the connection block 32 presses the elastic block 41 to slide toward the inside of the fixed cylinder 31 and compresses the second spring 42. At this time, the second spring 42 always has a force for driving the elastic block 41 to rebound, but when the clamping block 33 clamps the connecting block 32 in the fixed cylinder 31, the second spring 42 cannot drive the elastic block 41 to rebound. When the hook body 2 needs to be disassembled, the clamping block 33 is pressed back into the guide hole 321 again, the second spring 42 can be stressed to release the rebound and reset of the driving spring block 41, and the connecting block 32 can be rapidly ejected out of the fixed cylinder 31, so that the hook body 2 can be rapidly and automatically separated from the fixed cylinder 31. At this time, even the connection block 32 and the spring block 41 may be made of magnet materials; the connecting block 32 can be attracted with the elastic block 41, so that the connecting block can be more smoothly and accurately attracted and inserted into the fixed cylinder 31, and the actual installation is convenient.

In the embodiment of the present utility model, referring to fig. 2, the hook body 2 includes a hook cylinder 21 and a hook head 22, the hook cylinder 21 is connected with a connection block 32, and the hook head 22 is screwed inside the hook cylinder 21. In actual operation, the front end of the hook head 22 is a round head or a pointed head, and the hook cylinder 21 and the hook head 22 are made of stainless steel so as to ensure the use effect. Meanwhile, when the hook head 22 is rotated, the aim of adjusting the length of the hook body 2 can be fulfilled by adjusting the relative hook cylinder 21, so that the hook bodies 2 with different lengths can be conveniently adjusted according to different conditions, and the adaptability of the hook bodies 2 is improved; even if necessary, the hook head 22 can also be used for adaptively replacing the bone hook required by the current or subsequent operation at any time according to the field condition, so that the purpose of matching different operation environments can be achieved by independently changing the model of the hook head 22, and the use is very flexible.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
