Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical auxiliary instruments, and in particular to a probe hook for medical arthroscopic surgery. Background Art
[0002] With the aging of the population, the incidence of joint diseases such as osteoarthritis is gradually increasing. Arthroscopy, as an important diagnostic and therapeutic method, plays an increasingly important role in the treatment of joint diseases. Among them, the arthroscopic probe is a commonly used tool in knee arthroscopy. It can be used to feel the articular cartilage and evaluate the hardness of the cartilage or the degree of meniscus tear. It can also be used to detect the extent of cartilage defects, cruciate ligaments or other abnormal structures in the joint.
[0003] At present, a plurality of scale lines are arranged at intervals on the detection part at the front end of the arthroscopic probe hook, which facilitates the physician to make accurate observations. However, during arthroscopic surgery, the joint cavity often contains accumulated fluid, and the existing probe hook cannot remove the accumulated fluid or has a poor removal effect. The surgeon needs to change the operating instrument, and then switch back to the probe hook to continue observation after draining the accumulated fluid. Frequent replacement of instruments leads to cumbersome operation and low efficiency. Utility Model Content
[0004] In order to improve the efficiency of the probe hook in draining the accumulated fluid, the present application provides a probe hook for medical arthroscopic surgery.
[0005] The present application provides a probe hook for medical arthroscopic surgery, which adopts the following technical solution:
[0006] A probe hook for medical arthroscopic surgery includes a detection part and a rod body. The detection part is provided with multiple groups of scale lines at intervals and is used to detect the damage condition of the damaged position. The rod body is connected to the detection part and is convenient for the doctor to operate the probe hook. The detection part and the rod body are provided with drainage channels for discharging the accumulated fluid at the detection part.
[0007] By adopting the above technical scheme, the damage condition of the damaged position can be easily detected through multiple sets of scales on the detection part. At the same time, the accumulated fluid in the joint cavity enters the drainage channel through the detection part, and the accumulated fluid inside the detection part is discharged from the tail end of the rod body through the drainage channel, thereby improving the drainage efficiency of the probe hook for the accumulated fluid.
[0008] Furthermore, the detection part is composed of a first measuring rod and a second measuring rod, the first measuring rod and the second measuring rod are connected to each other and form an angle, the first measuring rod and the second measuring rod are provided with a plurality of scale lines at intervals, the scale lines are annular structures, and the second measuring rod is provided with numbers for marking distances.
[0009] By adopting the above technical solution, the multiple scale lines spaced apart on the first measuring rod and the second measuring rod facilitate measurement of the damaged position, and the measurement accuracy is improved by the annular scale lines and the numbers marking the distances. At the same time, the first measuring rod and the second measuring rod that are connected to each other and have a certain angle facilitate measurement in two directions, thereby improving the detection effect of the detection unit.
[0010] Furthermore, one end of the first measuring rod away from the axis of the second measuring rod is in a spherical structure, the first measuring rod and the second measuring rod are vertically connected to each other, and the length of the second measuring rod is greater than that of the first measuring rod.
[0011] By adopting the above technical solution, the first measuring rod mainly measures the width of the damaged position, and the second measuring rod mainly measures the depth of the damaged position. The tip of the first measuring rod is a spherical structure, which reduces the damage of the first measuring rod to the patient's body tissue and thus reduces the patient's pain.
[0012] Furthermore, the interior of the second measuring rod is hollow, and a plurality of rows of water absorption holes are arranged in a circular array along the axial direction of the second measuring rod, and the water absorption holes are connected to the interior of the second measuring rod.
[0013] By adopting the above technical solution, the multiple groups of water absorption holes on the side wall of the second measuring rod can absorb the accumulated liquid on the side wall of the second measuring rod into the interior of the second measuring rod in time, so as to improve the drainage efficiency of the probe hook for the accumulated liquid.
[0014] Furthermore, the multiple groups of water absorption holes in the same row on the side wall of the second measuring rod are arranged at intervals, and the water absorption holes in different rows are staggered.
[0015] By adopting the above technical solution, different rows of water absorption holes are staggered to effectively discharge the accumulated liquid at the measuring part, while ensuring the carrying capacity of the probe hook.
[0016] Furthermore, a circular through hole is opened inside the rod body along the axis, and the circular through hole is connected to the inside of the second measuring rod. The diameter of the circular through hole is equal to the diameter of the hollow inside the second measuring rod. A drainage port for discharging the accumulated liquid in the circular through hole is opened on the side wall of the rod body away from one end of the second measuring rod. The water absorption hole, the internal channel of the second measuring rod, the circular through hole and the drainage port together constitute a drainage channel.
[0017] By adopting the above technical solution, the water absorption hole absorbs the accumulated fluid in the joint cavity into the internal channel of the second measuring rod, and then flows into the circular through hole, and finally is discharged through the drain port, thereby forming a drainage channel for discharging the accumulated fluid at the second measuring rod.
[0018] Furthermore, a handle is sleeved on one end of the rod body away from the second measuring rod, which facilitates the doctor to operate the probe hook.
[0019] By adopting the above technical solution and installing a handle on the rod body, it is convenient for doctors to operate the probe hook.
[0020] Furthermore, a tail cap for closing the circular through hole and the drain outlet is clamped on the tail of the rod body away from the second measuring rod. The tail cap can rotate along the axis of the rod body, and an adjustment hole for discharging the accumulated liquid out of the drain outlet is provided on the side wall of the tail cap. The tail cap is rotated to adjust the overlap between the drain outlet and the adjustment hole.
[0021] By adopting the above technical solution, when in use, rotate the tail cap, and when the drain outlet and the adjusting hole completely overlap, the accumulated liquid discharged from the drain outlet is all discharged through the adjusting hole. At this time, the amount of accumulated liquid discharged from the drain outlet is the largest. When the overlap degree of the drain outlet and the adjusting hole is zero, the accumulated liquid discharged from the drain outlet is blocked by the side wall of the tail cap, thereby closing the drain outlet, and then realizing the adjustment of the liquid discharge amount of the drain outlet.
[0022] Furthermore, an anti-slip layer is provided on the outer sides of the handle and the tail cap.
[0023] By adopting the above technical solution, the anti-slip layer is a knurled layer opened on the surface of the handle and the tail cap. The anti-slip layer reduces the probability of slipping when the operator holds the device, and also improves the doctor's operating feel.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] The multiple sets of scales on the first measuring rod and the second measuring rod facilitate detection of the damage condition of the damaged position. At the same time, the multiple sets of water absorption holes absorb the accumulated fluid in the joint cavity into the internal channel of the second measuring rod, and then flow into the circular through hole, and finally discharged through the drain port and the adjustment hole, thereby improving the drainage efficiency of the probe hook for the accumulated fluid.

The second measuring rod 22 is also There are multiple scale lines 23 at intervals, and the scale lines 23 on the second measuring rod 22 also surround the second measuring rod 22. The length of the second measuring rod 22 is greater than the length of the first measuring rod 21. There are more scale lines 23 on the second measuring rod 22. In order to facilitate reading, numbers for marking distances are engraved on the second measuring rod 22. The first measuring rod 21 and the second measuring rod 22 of this embodiment are perpendicular to each other. In order to improve the verticality of the first measuring rod 21 and the second measuring rod 22, the first measuring rod 21 is welded and installed on the side wall of the second measuring rod 22 near the top.
