Description
本發明係關於一種自動施夾器，尤指一種施夾單元可旋轉以調整手術時的施夾方向之自動施夾器。The present invention relates to an automatic clip applier, and more particularly to an automatic clip applier that can be rotated to adjust the direction of application of the clip during surgery.
於手術進行中，時常需要對血管施予暫時閉合，以避免血液由手術部位的切口流失。為此，至今已發展有許多用於閉合血管之外科用器具，其中，最常見之閉合血管方法為，使用一施夾器(clip applier)夾取一血管夾(ligating clip)，再藉由施夾器，鉗壓血管夾，俾使血管夾變形而得以閉合血管。因此，為節省夾取血管夾之步驟，目前市面上已有可提供複數個血管夾之自動施夾器。During the operation, it is often necessary to temporarily close the blood vessel to avoid blood loss from the incision in the surgical site. To this end, many instruments for closing blood vessels have been developed to date, and the most common method of closing blood vessels is to use a clip applier to grasp a ligating clip and then apply it. The clamp clamps the blood vessel clamp and deforms the blood vessel clip to close the blood vessel. Therefore, in order to save the step of clamping the blood vessel clip, an automatic clip applier that can provide a plurality of blood vessel clips is currently available on the market.
所謂之自動施夾器，即為已貯放有複數個血管夾之施夾器，其可依序將血管夾傳送至夾持部(鉗口)。因此，當外科醫師夾閉血管時，可直接使用自動施夾器夾閉血管，而無需經過夾取血管夾之步驟。更具體而言，於夾閉欲截切處之血管的過程中，當位於夾持部之血管夾因鉗壓變形而夾閉血管一端後，另一血管夾會被自動傳送至夾持部，故外科醫師無須重新夾取血管夾，即可使用同一自動施夾器直接鉗壓以夾閉血管之另一端。The so-called automatic clip applier is a clip applier that has stored a plurality of blood vessel clips, which can sequentially transfer the blood vessel clip to the clamping portion (clamp). Therefore, when the surgeon clamps the blood vessel, the blood vessel can be directly clamped using the automatic clip applier without the step of gripping the blood vessel clip. More specifically, in the process of clamping the blood vessel to be cut, when the blood vessel clip located at the clamping portion clamps one end of the blood vessel due to the clamping deformation, the other blood vessel clip is automatically transmitted to the clamping portion. Therefore, the surgeon does not need to re-clamp the blood vessel clamp, and can directly clamp the other end of the blood vessel using the same automatic clip applier.
然而，由於手術時目標物的角度不同，外科醫師必須改變施夾器之操作方向，以夾閉血管；但施夾器之操作方向改變時，可能造成外科醫師施力不便。有鑑於此，若能發展出一種施夾單元可旋轉的施夾器，則能改善前述之缺陷，而幫助外科醫師手術過程之操作便利性。However, due to the different angles of the target during surgery, the surgeon must change the direction of operation of the clip applier to clamp the blood vessel; however, the direction of operation of the clip applier may cause inconvenience to the surgeon. In view of this, if a clip applier capable of rotating the clip unit can be developed, the aforementioned defects can be improved, and the operation convenience of the surgeon's surgical procedure can be improved.
