Technical Field

The utility model relates to a bone grafting device, in particular to an arthroscopic intra-articular bone grafting device, which belongs to the field of bone grafting devices for orthopedics department.

Background

Intra-articular fractures are a common type of fracture in the clinic. In the past, when an intra-articular fracture is treated, a joint capsule needs to be cut in order to expose a fracture end, and the tissue structure of the joint is greatly damaged. With the popularization and application of arthroscopic technology in clinic in recent years, a part of intra-articular fracture can be restored and fixed under the arthroscope, so that the damage to the joint tissue structure is greatly reduced. However, for a part of intra-articular fractures needing bone grafting, due to the limitation of arthroscopic surgical instruments, simple and efficient bone grafting cannot be performed under minimally invasive conditions, and an incision needs to be enlarged or a new large incision needs to be made at other positions so as to expose a fractured end for bone grafting. Therefore, not only are surgical trauma, intraoperative hemorrhage and surgical time increased, but also the recovery time is prolonged, the treatment cost of a patient is increased due to a new incision, and the purpose of violating the minimally invasive arthroscopic surgery is achieved.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses an articular implanter under arthroscope can carry out the articular implantation bone under the arthroscope portably, the efficient. The operation hole of the arthroscope is used for bone grafting, and the purpose of minimally invasive arthroscope operation is achieved. Not only reduces the operation trauma, reduces the bleeding during the operation, shortens the operation time, promotes the faster recovery of the patient after the operation, but also reduces the treatment cost and lightens the economic burden of the patient and the society.

The technical scheme of the utility model is that:

the arthroscopic intra-articular bone grafting device comprises a bone grafting device body, wherein the bone grafting device body consists of a sleeve and a push core; one end of the push core is inserted into the sleeve; the other end of the push core is provided with a depth limiting clamping support; the other end of the depth limiting clamp support is provided with a core pushing ring, the sleeve is provided with a bone grafting groove, and the bone grafting groove is communicated with the interior of the sleeve; one end of the sleeve is provided with two sleeve finger rings, and the two sleeve finger rings are arranged on two sides of the sleeve. The bone grafting device has uniform thickness and smooth surface, the push core and the sleeve are tightly jointed and smoothly pushed and pulled, and the cross section of the bone grafting device is oval.

One end of the sleeve is a horizontal cross section, and the other end of the sleeve is an oblique section.

The bone grafting groove is a funnel arranged on the sleeve, is elliptical and is used for containing bone grafting, and the bottom of the bone grafting groove is continuously communicated with the sleeve; the push core is arranged below the bone grafting groove, the opening size of the bottom of the funnel and the sleeve connecting port is adjusted through the movement of the push core, and the amount of the grafted bone entering the sleeve is controlled.

The sleeve ring is oval, and is used for placing an indication finger and a middle finger of an operator and operating the sleeve.

The core pushing ring is used for placing the thumb of an operator and is used for operating the advance and retreat of the core pushing.

The core pushing ring is continuous with the core pushing ring through the depth limiting clamping support.

The depth limiting clamping support corresponds to the sleeve in size and shape and can prevent the push core from excessively penetrating.

The other end of the push core is also an oblique section and is solid. The length of the sleeve is slightly longer than that of the sleeve, so that the waste caused by the fact that the transplanted bone is remained in the sleeve due to the fact that the push core is short and small can be avoided, and the pressure bone grafting is also facilitated when the bone is grafted.

The utility model has the advantages that: can implant bones in joints simply and efficiently under an arthroscope. The operation hole of the arthroscope is used for bone grafting, and the purpose of minimally invasive arthroscope operation is achieved. Not only reduces the operation trauma, reduces the bleeding during the operation, shortens the operation time, promotes the faster recovery of the patient after the operation, but also reduces the treatment cost and lightens the economic burden of the patient and the society. The utility model has novel structure, convenient and efficient use, exact effect and standardized operation rules, and achieves the purpose of the invention.

The present invention will be further explained with reference to the drawings and examples.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

Example 1

As shown in fig. 1-3, an arthroscopic intra-articular bone grafting device comprises a bone grafting device body, wherein the bone grafting device body is composed of a sleeve 1 and a push core 2; one end of the push core 2 is inserted into the sleeve 1; the other end of the push core 2 is provided with one end of a depth limiting clamping support 3, the other end of the depth limiting clamping support 3 is provided with a push core finger ring 4, the sleeve 1 is provided with a bone grafting groove 5, and the bone grafting groove 5 is communicated with the interior of the sleeve 1; one end of the sleeve 1 is provided with two sleeve finger rings 6, and the two sleeve finger rings 6 are arranged on two sides of the sleeve 1.

The bone grafting instrument body is made of stainless steel and has a total length of 13.1cm, wherein the upper edge of the sleeve is 10cm long, and the lower edge of the sleeve is 9cm long; the upper edge of the push core is 10.1cm long, and the lower edge of the push core is 9.1cm long; the depth limiting card support is 1.5cm long. The bone grafting device has uniform thickness and smooth surface, the push core and the sleeve are tightly jointed and smoothly pushed and pulled, and the cross section of the bone grafting device is oval.
