[0001]This disclosure relates to the field of medical instruments, in particular to a locking mechanism of morcellator.
BACKGROUND OF INVENTION
Description of the Related Art
[00021 Traditional surgery is an open surgery, and common surgical methods include incision, puncture, insertion, etc. However, the traditional surgery not just has a large surgical wound only, but also requires a long recovery time. With the advancement and innovation of technology, minimally invasive surgeries have been proposed and applied in surgeries, giving doctors and patients more options for treatment.
[0003]In more detail, the minimally invasive surgeries are often used in abdominal surgery and thoracic surgery. In the minimally invasive surgeries, a small incision is made on a patient's body, a puncture unit of a trocar is passed through the small incision, and a trocar sleeve on the trocar is fixed to the patient's body at a proper angle.
Then, the puncture unit is pulled out, so that the trocar sleeve can be used as a passage for other surgical instruments. Further, surgeries such as tissue removal or burning can be done by endoscope, electric cautery and other medical instruments, and thus the minimally invasive surgery has the advantages of small wounds, shortened recovery time, and reduced pain.
[0004]With reference to FIG. 2 for a conventional surgical instrument as disclosed in European Patent Publication No. EP3545893A I, this conventional surgical instrument was clinically found that an end of the surgical instrument is often pushed out of the housing of the surgical instrument during operations due to the reaction force of the patient's tissue on the surgical instrument. For example, when a doctor operates a surgical instrument with a puncture unit and the front end of the puncture unit touches the patient's tissue, the trocar receives a reaction force, which causes parts of the surgical instrument to be pushed out of the trocar housing by the reaction force.
[0005]In practical experience, the doctor has to hold the surgical instrument with a hand, and press the rear end of the housing with the other hand, which causes inconvenience and difficulty in the surgical operation. Obviously, the conventional surgical instrument requires further improvements. In view of the aforementioned drawback of the prior art, the discloser of this disclosure based on years of experience in the related industry to conduct extensive research and experiment, and finally developed a locking mechanism of morcellator in accordance with this disclosure.
SUMMARY OF THE INVENTION
[0006]Therefore, it is a primary objective of this disclosure to provide a locking mechanism of morcellator including a main body, a puncture unit and a fixing unit. Wherein, the main body includes a grip portion and a passage, and the passage has a first port and a second port. The puncture unit is installed in the passage, and an end of the puncture unit is extended out from the first port of the passage. It is noteworthy that the fixing unit is coupled to the other end of the puncture unit, and the fixing unit can be engaged with the second port. By the design of the fixing unit, the puncture unit can be securely installed in the passage to improve the convenience and efficiency of the surgical operation.
[0007] To achieve the aforementioned and other objectives, this disclosure discloses an embodiment of a locking mechanism of morcellator, and the morcellator includes: a main body having a gip portion and a passage, wherein the passage has a first port and a second port; a puncture unit, installed in the passage, and having an end extended out from the first port; and a fixing unit, coupled to the other end of the puncture unit; wherein, when the puncture unit is set in the passage, the fixing unit is rotated in a first direction to switch the fixing unit from an unengaged status into an engaged status, so as to the engage the fixing unit with the inside of the main body; when the fixing unit is rotated in a second direction which is opposite to the first direction, the fixing unit is switched from the engaged status into the unengaged status to disengage the fixing unit from the main body.
[0008] To achieve the primary objective of this disclosure, the fixing unit includes a cover; a plurality of engaging members, disposed on a lower surface of the cover, for engaging the plurality of engaging slots of the main body respectively; and a grip portion, formed on the cover.
