Description

Technical Field

[0001] The utility model relates to the technical field of arthroscopic treatment equipment, and particularly relates to a multifunctional arthroscopic access guide rod. Background Technique

[0002] The hip joint is composed of the femoral head and the acetabulum, belonging to a ball-and-socket joint. The lunate surface in the acetabulum is covered with articular cartilage, and the acetabular fossa is filled with fat, also known as the Haversian gland, which can be extruded or inhaled with the increase or decrease of the intra-articular pressure to maintain the balance of the intra-articular pressure. There is an attachment of the glenoid labrum at the edge of the acetabulum, which deepens the wrapping and stability of the acetabulum to the femoral head. There is an acetabular transverse ligament straddling the acetabular notch, and together with the notch, it forms a hole through which nerves, blood vessels, etc. pass. The functional lesions of the hip joint mainly include femoroacetabular impingement syndrome, acetabular labral injury, osteoarthritis, aseptic osteonecrosis (such as femoral head necrosis, etc.), certain hip fractures (such as femoral neck fractures), rheumatoid arthritis, traumatic arthritis, benign and malignant bone tumors, ankylosing spondylitis, etc. When arthroscopic surgery technology can be used to minimally treat hip joint diseases, the surgical trauma is small and the recovery is fast, but the technology is complex and the requirements for surgical instruments are high.

[0003] An arthroscope consists of a lens, a light source, a monitor, arthroscopic surgical instruments, etc. During the operation, the doctor makes multiple incisions at the corresponding parts of the joint, inserts the arthroscope into the joint through one of the incisions, and the arthroscope is connected to the monitor through a wire. In this way, the situation inside the joint can be clearly displayed, and the impact of the lesion on the joint can also be dynamically observed. The doctor can make a clear diagnosis of the condition inside the joint, and at the same time insert surgical instruments through other incisions and then perform the operation.

[0004] Hip arthroscopic surgery uses an arthroscope and surgical instruments to enter the joint cavity through a minimally invasive small incision on the skin to treat damaged structures within the joint cavity. Since the hip joint is surrounded by thick muscle and fat tissue, it is very difficult to find the correct direction and path from the skin surface into the hip joint space. Therefore, the surgeon needs to use X-ray fluoroscopy to determine the position of the hip joint space, then use a puncture needle to puncture in the general direction of the hip joint space, and perform fluoroscopy again to confirm whether the position of the puncture needle is correct, so as to find the correct direction and path to enter the joint cavity. However, since the hip joint space is very narrow, about 1 cm, and is often interfered by soft tissues such as muscles around the hip joint during puncture, this process is often not smooth and requires repeated fluoroscopy and puncture processes to finally find the correct path. This not only increases the radiation exposure of medical staff and patients, but repeated punctures may also damage the neurovascular structures around the patient's hip joint, causing corresponding iatrogenic complications. Therefore, there is an urgent need for a device that can find the correct direction and path to enter the joint cavity without the aid of X-ray fluoroscopy and has the function of bluntly separating the tissues around the hip joint. Therefore, this device provides a multi-functional arthroscopic access guide rod. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-functional arthroscopic access guide rod for the deficiencies of the prior art to solve the above-mentioned technical problems.

[0006] The embodiment of the present invention adopts the following technical solutions: It includes an access guide rod for pathfinding and tissue separation in arthroscopic treatment. The access guide rod is hollow and the hollow is used to insert a guide wire or a puncture needle required for treatment. An open chute is provided on the side wall of the hollow of the access guide rod from the head end to the tail end, and the head end of the access guide rod is provided in a tongue depressor shape.

[0007] Further, the outer surface of the tongue depressor shape at the head end of the access guide rod is arc-shaped.

[0008] Further, the width of the tongue depressor shape at the head end of the access guide rod gradually decreases from large to small with reference to the width close to the tail end of the access guide rod.

[0009] Further, the tail end of the access guide rod is provided in a conical shape.

[0013] Further, the thickness of the tongue depressor shape at the head end of the access guide rod gradually becomes thinner closer to the tail end.

[0014] The above at least one technical solution adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0015] When medical staff treat patients with hip joint diseases, first insert the head end of the access guide rod into the surface of the hip joint capsule, and move the access guide rod to bluntly separate the tissues around and on the surface of the hip joint capsule through the tongue-shaped head end, and feel for the "soft spot feeling", that is, find the joint capsule area on the surface of the joint space. After finding the "soft spot", the puncture needle punctures the joint capsule in the "soft spot" area through the semi-open sliding groove of the access guide rod and enters the joint space. It realizes finding the correct direction and path to enter the joint cavity without the aid of X-ray fluoroscopy. After the puncture needle extends into the joint space, subsequent operations such as expanding the access channel and treatment can be carried out. BRIEF DESCRIPTION OF THE DRAWINGS
