Description

Surgical instrument matched with arthroscope for use
Technical Field
The invention relates to the technical field of medical instruments, in particular to a surgical instrument matched with an arthroscope.
Background
In recent years, arthroscopic surgery has been widely used in the field of orthopedics and sports medicine. The arthroscope which is commonly used in clinic at present controls capillary hemorrhage in the joint cavity through physiological saline perfusion, so that a satisfactory scope view is obtained. Continuous saline infusion requires that the joint cavity be a relatively tight space, which is often easily achieved in simple single or dual channel arthroscopic surgery. However, complex arthroscopic surgery often requires multiple arthroscopic channels to be established, and frequent switching between the viewing channel and the operative channel is required during surgery, where extravasation of saline perfusate becomes a "rate limiting" element that limits the smooth progress of the surgery.
In theory, the extravasation of saline perfusate can lead to several problems including 1. Reduced perfusion pressure in the joint cavity, increased capillary hemorrhage, blurred vision under the scope, 2. Reduced volume of the joint cavity, reduced operating space, 3. Swelling of the interstitial spaces outside the joint cavity, increased incidence of postoperative osteofascial syndrome, 4. Separation of the epidermis incision and the joint capsule incision due to extravasation of perfusate into the interstitial spaces, reduced patency of arthroscope channels, 5. Massive extravasation of joint perfusate, contamination of the operating table, and easy iatrogenic infection.
In order to reduce the extravasation of normal saline perfusate, capillary hemorrhage can be clinically reduced by using a tourniquet, but the method is only suitable for arthroscopy operation of distal limbs such as knee, ankle, elbow and wrist, and the use time of the tourniquet is strictly limited, usually not more than 1.5 hours, otherwise, the bleeding complications of the limb after operation are easily caused. In addition, for operations such as hip and shoulder, which cannot use tourniquets, a method of controlling blood pressure reduction in general anesthesia is generally used clinically to reduce capillary osmotic pressure, but the method can cause the craniocerebral blood pressure of a patient to be reduced, so that the operation time is also severely limited.
In order to solve the problems, a special matched instrument for arthroscopic surgery, which is convenient to use, simple in structure, safe and practical, needs to be developed, and is one of the tasks to be completed in the current field.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 9, the working principle of the present invention is described below with reference to the accompanying drawings:
In the initial state (see fig. 1), the sleeve core rod 17 is positioned in the sleeve 16, and the straight-line-shaped strip on the base circular plate 3 is matched with the straight-line-shaped groove arranged in the annular boss 20 to complete seamless connection. The outer sheath 7 is initially closed and the valve 5 is likewise in a closed condition.
Secondly, the instrument of the invention is put in (see fig. 8 and 9), a surgical knife 19 is firstly cut on the skin of a patient by using a surgical knife, then the instrument of the invention in an initial state is penetrated into the skin by the surgical knife 19, and the joint capsule is penetrated into the joint cavity by using the conical tip 10. Next, the position and depth of the instrument of the present invention is determined under arthroscopic monitoring. The adjusting handle 14 is pushed rightwards to enable the compression folding area 8 positioned in the surgical knife edge 19 to be in an unfolding state, at the moment, the length of the outer sheath tube 7 is shortened, the curve end face 15 of the adjusting handle 14 is kept in contact with the branch pipe 4, and the curve end face 15 is stably propped against. Next, the stop collar 13 is slid to the right along the outer sheath tube 7 until it is confirmed that the stop collar 13 compresses the patient cortical tissue 18 with the compressed fold 8 in the expanded state, preventing extravasation of perfusate outside the body or tissue space during arthroscopic surgery. Finally, the core rod 17 is pulled out of the sleeve 16,
Third, during the surgical operation (see fig. 7), other arthroscopic instruments may directly enter the joint cavity via the unidirectional opening and closing piston disposed inside the cannula 16. When the pressure in the joint cavity is too high, part of joint perfusate can be released through the valve 5 to regulate the pressure. In addition, because the instrument is directly communicated with the inside and the outside of the joint cavity, the external knot can be smoothly sent into the joint cavity through the center of the sleeve 16, thereby effectively avoiding the incarceration effect caused by the possible knot of soft tissues around the arthroscope channel, greatly simplifying the operation steps and saving the operation time.
Fourth, after the operation is finished, the sleeve rod 17 is firstly replaced in the sleeve 16, and the adjusting handle 14 is pulled leftwards under the monitoring of the arthroscope, so that the transverse slit 11 of the outer sheath tube 7 is closed. And simultaneously, the limit ring 13 is moved leftwards, the tissue gap between the joint capsule and the skin is loosened, and the instrument is slowly pulled out of the body. Finally, the skin is sutured, and the operation is completed.
Those skilled in the art can also make appropriate changes and modifications to the above-described embodiments in light of the disclosure and teachings of the above specification. Therefore, the invention is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the invention should be also included in the scope of the claims of the invention. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not limit the present invention in any way.
