Description

Technical Field

[0001] The present invention relates to a medical device, specifically an aspirator for aspirating tissue fluid during arthroscopic operations. Background Art

[0002] During arthroscopic operations, in order to keep the intraoperative field of view clear, the water outlet system is very important. Currently, the water outlet methods mainly include water outlet from the shaver system (operation access) and water outlet from the sheath tube system (observation access). However, both water outlet systems have their own advantages and disadvantages: 1. When the water outlet from the sheath tube system, the operation field of view is poor after water outlet and the effect is not good, because only a short water flow cycle is formed with its own water inlet system, and there is no water flow cycle at the joint operation site, and the field of view is not clear. 2. When the water outlet from the shaver system, the operation field of view is clear after water outlet and the effect is better, because it forms a long water flow cycle with the water inlet system, and the joint operation site can maintain a clear field of view. However, it can only perform a single shaving operation and cannot perform other joint operations such as vaporization, positioning, grinding, suturing, etc., which is inconvenient for surgical operations. During the operation, the shaver system needs to enter and exit the joint cavity multiple times, seriously affecting the operation time and causing possible multiple soft tissue injuries.

[0003] In deep tissues such as the posterior joint capsule of the knee joint, the glenohumeral joint cavity of the shoulder, and the hip joint cavity, etc., often due to surgical operations or increased blood pressure, bleeding in the joint cavity causes blood staining or turbidity, seriously affecting the field of view. Usually, the shaver system is used for water outlet. During the operation, the shaver system needs to penetrate into the deep tissue repeatedly multiple times to aspirate until the field of view is clear and then perform secondary operations. Such repeated operations may significantly prolong the examination or operation time, increase the risks of anesthesia, wound infection, etc., and also increase the operation time and cost.

The puncture end of the auxiliary puncture needle 2 extends beyond the inner end of the semi-circular suction tube 11. The other end of the auxiliary puncture needle 2 extends to the tail handle 12.

[0023] Since the suction device 1 needs to be left on the human body and the suction device 1 realizes the operation of introducing operating instruments during arthroscopic surgery, the miniaturized design of the tail handle 12 of the suction device 1 is beneficial to the operation of the surgical instruments. However, the miniaturized design of the tail handle 12 causes inconvenience in holding during the puncture operation. To solve the above technical contradiction, in this specific embodiment, a detachable handheld operating handle 3 is adopted. The handheld operating handle 3 has a suction device positioning and mounting portion 31 for detachably fixing the tail handle 12, a needle holder 32 for fixing the auxiliary puncture needle 2, and a handheld handle body 33 for handheld operation. The handheld operating handle 3 fixedly connects the auxiliary puncture needle 2 and the suction device 1 into a whole, realizes the detachable installation of the auxiliary puncture needle 2 on the suction device 1, and at the same time facilitates handheld puncture operation; after the puncture is completed, the handheld operating handle 3 is detached and the auxiliary puncture needle 2 is pulled out; the handheld operating handle 3 provides a handheld part during the puncture operation, and the tail handle 12 facilitates the subsequent operation of pulling out the suction device 1, and the volume of the tail handle 12 can be miniaturized, and there is no problem of operation interference for the reserved suction device 1.

[0024] Further, the suction device positioning and mounting portion 31 includes a sleeve pipe 311. The tail handle 12 of the suction device 1 is axially inserted and fitted with the sleeve pipe 311, and a hand-tightening locking bolt 312 for locking the tail handle 12 is provided on the sleeve pipe 311. The tail handle 12 of the suction device 1 is inserted into the sleeve pipe 311 and locked by the hand-tightening locking bolt 312, which has the advantages of firm and reliable connection. Moreover, the insertion direction of the tail handle 12 is the same as the disassembly and assembly direction of the auxiliary puncture needle 2, so that the auxiliary puncture needle 2 can be pulled out and assembled on the suction device 1 by holding the operation handle 3, which has the advantage of convenient operation. Moreover, the auxiliary puncture needle 2 and the tail handle 12 cooperate to achieve a positioning function.

The plug mounting piece 42 has a holding ring 421, and the positioning piece 43 has a clearance space 44 corresponding to the position of the self-closing plug. The plug mounting piece 42 and the positioning piece 43 are both provided with positioning bayonet a that are positioned and matched at the two lateral edges of the guide recess 111. Under this structural design, the saddle seat is positioned at the edge of the half-moon suction tube 11 to achieve installation and guidance, which has the advantages of simple and compact structure, and the double-piece (plug mounting piece 42 and positioning piece 43) positioning and guiding is more stable and reliable.

[0029] A hand-held piece 46 for hand-holding operation is extended obliquely upward from the connecting portion 45 toward the tail handle 12, so that the occluder 4 can be held by hand for moving operation, and the operation is more convenient.

[0030] The operation method of the aspiration kit for arthroscopic surgery of the present invention is as follows: Adjust the auxiliary puncture needle 2 to an appropriate length and fix it on the handheld operating handle 3. Insert the auxiliary puncture needle 2 into the guiding recess 111 until it is fully inserted. At this time, the sleeve tube 311 is sleeved on the tail handle 12, and the hand-tightening locking bolt 312 is tightened to achieve the puncture operation. After the puncture is completed, loosen the hand-tightening locking bolt 312, remove the handheld operating handle 3 with the auxiliary puncture needle 2, and the guiding recess 111 of the semi-circular aspiration tube 11 forms a guiding path. The plug 4 can be pre-installed on the aspirator 1 or assembled on the aspirator 1 after removing the auxiliary puncture needle 2, and move the plug 4 to seal the human puncture opening. Then, corresponding surgical operations can be performed according to the actual surgical needs. The aspirator 1 provides the function of instantaneously controllable water output to keep the visual field clear during various arthroscopic operations, providing a good surgical visual field for the surgeon, and also facilitating the surgeon to operate the water output and other various operations, such as drilling tunnels, implanting rivets, vaporization, positioning, suturing, grinding, etc. with one hand at the same time, thereby avoiding the time waste caused by repeatedly entering and exiting the shaver system due to the inability to operate under a clear visual field, achieving the purpose of shortening the surgical time, simplifying the operation of the surgeon, and reducing the risk of soft tissue injury and infection caused by multiple operations.
