Description

Technical Field

[0001] The invention relates to a laparoscopic surgery auxiliary device. Background Art

[0002] Laparoscopic surgery is a minimally invasive treatment method in which instruments are inserted through a tiny incision in the patient's abdominal wall for observation and cutting. Large pieces of diseased tissue or solid organs removed from the abdominal cavity are usually cut into pieces and removed using an electric tissue morcellator. Due to the tiny incision in the abdominal wall, small-caliber tissue morcellator tubes are currently used for morcellation. The small-caliber tissue morcellator tube is inserted into the small-caliber outer tube of the matching electric base, and the lock coaxially rotates to play the role of cutting diseased tissues and organs. It is widely used in clinical practice. This method effectively ensures the minimally invasive and beautiful appearance of the patient's abdominal wall. The small-caliber electric base is light and convenient to use, but it takes a long time for the small-caliber knife tube to cut and morcellate large pieces of tissue. With the development of laparoscopic technology, vaginal-assisted laparoscopic surgery uses a large-caliber incision deep in the vagina, which provides the possibility for the clinical application of large-caliber tissue morcellator tubes, and is expected to achieve rapid morcellation and removal. However, large-caliber rapid tissue morcellator tubes are not compatible with the small-caliber standard electric base currently widely used in clinical practice, which limits clinical application.

[0003] Since small-caliber electric bases are light and convenient for clinical use and are purchased in large quantities by hospitals, in order to make full use of the existing small-caliber electric bases, the innovative development of large-caliber tissue fragmentation and rotary cutting knife tubes that are compatible with small-caliber electric bases has clinical application value. Summary of the invention

[0004] The present invention is to avoid the deficiencies of the above-mentioned prior art and invent a laparoscopic compatible reverse-button rapid tissue fragmentation and rotary cutting tool. A large-caliber knife tube is used at one end to meet the clinical demand for fragmenting large pieces of diseased tissue, and a unified small-caliber pipe is used at the other end to reversely insert and connect with a small-caliber electric base, and a protective device is added to prevent the rapidly rotating knife from falling off and damaging normal organs. The large-caliber knife tube is compatible with tumor-free protection bags, sealed protection channels, knife rotary cutting protection sheaths and expansion sealing plugs, thereby realizing minimally invasive tumor-free defense and efficient tissue removal function.

[0005] The present invention adopts the following technical solutions to solve the technical problems: 1. The laparoscopic compatible reverse-button rapid tissue shredding and rotary cutting tool is characterized by being composed of a large-caliber knife tube, a support ring, a standard connecting pipe, a drive base, an anti-slip ring and a sealing cap. The wide-mouth end of the support ring is connected to the large-caliber knife tube, and the other end is connected to the standard connecting pipe. A drive base is installed at one end of the standard connecting pipe, and an anti-slip ring and a sealing cap are provided on the drive base.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: Make full use of the existing small-caliber standard electric tissue pulverizer base to achieve clinical application compatible with large-caliber blade tubes; The large-caliber blade tube passes through the incision of natural cavities such as the vagina, and is equipped with a matching compatible tumor-free protection bag, a sealed protection channel, a knife rotary cutting protection sheath and an expansion sealing plug, achieving minimally invasive tumor-free defense, improving the efficiency of diseased tissue and organ fragmentation and removal, shortening the operation time, and making the patient safer.

[0011] The small-caliber electric tissue pulverizer base is light and flexible, is favored by surgeons and is widely used.

[0015] This case takes laparoscopic vaginal hysterectomy as an example.

[0016] After the patient is anesthetized and disinfected, and the whole uterus is removed under laparoscopy, the vagina is disinfected with iodine and a tightly sealed protective channel (3) with a self-sealing airtight sealing integrated device sealing cap is inserted. The tumor-free protective bag (5) is installed with an expansion sealing plug (3) and then inserted into the sealed protective channel (3). The bag opening is unfolded, and the auxiliary channel enters the instrument to grab the tissue and put it into the bag. The bag opening is pulled to 2 cm outside the tube opening of the sealed protective channel (3). The bag opening is unfolded and a tightly sealed tool rotary cutting protective sheath (2) with a self-sealing airtight sealing integrated device sealing cap is inserted. The 5 mm auxiliary sheath (541) and 10 mm endoscope sheath (542) of the tumor-free protective bag are pulled to the outside of the abdominal wall through the abdominal puncture channel respectively. After the sheath cap is removed, the puncture base (9) is replaced, and the tumor-free protective bag is inflated to form an intra-abdominal artificial isolation and protection of the small abdominal cavity (54). The channel is inserted with an endoscope and auxiliary instruments respectively.

[0017] After the sealing cap (16) is installed on the sealing cap holder (145), the front end of the electric motor handle (7) is inserted into the driving hole until the driving handle latch reaches the limit surface (143) of the driving base (14), and the large-caliber knife tube is rotated by fine adjustment until the latch is engaged in the driving slot (142). The outer thread (141) of the anti-slip ring of the driving base and the inner thread (151) of the anti-slip ring are rotated and tightened, and the tissue grasping forceps (8) are inserted into the large knife tube (1) with the sealing cap (16).

[0018] The large cutter tube (1) is inserted into the cutter rotary cutting protective sheath (2) together with the instrument, the instrument grabs and stretches the tissue (6) and drags it to the incision (111) of the large cutter tube, the auxiliary instrument enters from the base (541) to grab the tissue to prevent it from spinning, the motor drive switch is pressed, the large cutter tube (1) rotates to remove the tissue into the excision storage tube (113), the large cutter tube (1) and the tissue grasping forceps (8) are pulled out of the cutter rotary cutting protective sheath (2), at this time, the sealing cap of the self-sealing air-blocking sealing integrated device of the cutter rotary cutting protective sheath (2) is tightly sealed and air-blocked, the tissue grasping forceps (8) are pushed outside the abdominal cavity to push the tissue in the excision storage tube (113) out of the large cutter tube (1), and this step can be repeated to efficiently remove the tissue in the bag.

[0019] The above embodiments are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the spirit and essence of the design of the present invention, any equivalent changes or modifications made to the present invention should be included in the protection scope of the present invention.
