Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional traction aspirator. Background Art

[0002] The suction device, also known as the flushing and suction device, is the most basic instrument in laparoscopic surgery. Its main operations are flushing and suction. It is mainly responsible for sucking away the liquid in the operating cavity and flushing a large amount of fluid during surgery.

[0003] In open surgery, due to the wide field of vision, clear local exposure, large operating space, and wide operating space for various instruments, it is easy to handle. However, with the development of the times, people's pursuit of aesthetics, rehabilitation, and minimally invasive surgery has led to an increasing proportion of various laparoscopic surgeries, but there are very few retractors that can be used for tissue traction in minimally invasive surgery. At the same time, as more requirements are placed on the function of the aspirator, improvements to the aspirator are also urgently needed.

[0004] Based on this, the inventor hopes to design an aspirator with a pulling function, mainly to be able to expose the operating field as much as possible in the limited field of view and limited operating hole of laparoscopic surgery. The aspirator can assume part of the function of a retractor. Summary of the invention

[0012] Furthermore, in the above-mentioned multifunctional traction suction device, the upper part of the inner cavity of the connecting tube portion serves as a communication area for communicating with the diversion channel, and the lower part of the inner cavity of the connecting tube portion is provided with an internal thread groove for connecting with the external thread end in the suction tube.

[0013] Furthermore, in the above-mentioned multifunctional pulling suction device, the filtering assembly is composed of a supporting frame, a filtering frame and a pressing frame. The supporting frame is arranged in the lower layer, a plurality of filtering frames are provided and stacked in the middle layer, and the pressing frame is arranged in the upper layer.

[0014] Furthermore, in the above-mentioned multifunctional pulling suction device, the thickness of the support frame is equal to the inlet height of the guide channel, and the support frame is provided with a notch that matches the inlet length of the guide channel.

[0015] Furthermore, in the above-mentioned multifunctional pulling suction device, the filtering frame is composed of a frame body and a filtering grid located therein.

[0016] Furthermore, in the above-mentioned multifunctional pulling suction device, a convex buckle is provided on the outer side of the pressing frame, and a buckle groove cooperating with the convex block is opened on the side wall of the installation groove of the hook body.

[0017] Furthermore, in the above-mentioned multifunctional pulling suction device, the hook body, the supporting frame, the filtering frame and the pressing frame are all made by 3D printing of biological materials.

[0020] Pull, pull the strap muscle. In thyroid surgery, pulling the strap muscle can effectively expose the resection field;

[0021] Block, block blood vessels. When exposing iliac vessels during lymph node dissection, using a suction device to block veins can replace the role of separation forceps; block the bladder. When removing the uterus and suturing the vaginal stump, use a suction device to block the bladder to assist the surgeon in better suturing the vaginal stump.

[0022] When removing a large uterus, press down on the uterus to help expose the bladder peritoneal reflection; press down to block the intestine to help expose it; press the ureter to the side to keep it away from the hot electric instrument, and flush the ureter if necessary to reduce the risk of ureteral injury;

[0023] Lifting the uterus or appendages upward can expose the rectouterine pouch; lifting the obturator nerve upward can help remove the lymphatic tissue below the obturator nerve plane; lifting the lateral umbilical ligament upward can expose the iliopectine ligament, obturator fossa and deep inguinal lymph nodes.

[0024] 2. The retractor and suction tube of the present invention can be assembled in vivo, effectively reducing unnecessary body surface openings and trauma, and can be used for tissue traction under laparoscopic surgery; it can simultaneously perform blood flushing while traction of tissue during surgery without interrupting the surgical field of view.

[0025] 3. The retractor and filter assembly of the present invention are prepared by biomaterial 3D printing technology. The retractor has a smooth edge, which is helpful for tissue protection, especially in thyroid surgery. Compared with the needle-shaped design of the existing retractor, the plate-shaped hook design can avoid causing damage to the body.

[0026] 4. The handle of the present invention is equipped with a ventilating tube, and the suction function can be controlled by pressing with the thumb, which is convenient to operate.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
