Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a flushable endoscopic minimally invasive surgical instrument. Background Art

[0002] Mammoplasty is one of the common cosmetic surgeries. Secondary deformity and fibrous capsule contracture after mammoplasty are common complications of mammoplasty. Surgical treatment is the main method and means to treat the above common complications. The operation techniques involve fibrous capsule release, fibrous capsule incision, partial or complete fibrous capsule resection and fibrous capsule suturing, etc. Existing minimally invasive instruments used for chest surgery are not equipped with flushing devices, which makes the instrument smaller in size, can effectively reduce the size of the wound caused by the instrument, and reduce the patient's pain, but at the same time it also faces the problem of being unable to clean the removed muscle fibers or blood clots during surgery. Currently, they are scraped by a stripping knife. The sharp blade of the stripping knife is easy to cause new wounds, increase the patient's pain, affect the treatment effect, and give the patient a poor experience. Therefore, it is very necessary to design a surgical instrument that does not increase the wound and has a flushing function. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a flushable endoscopic minimally invasive surgical instrument that combines surgical stripping and flushing into one by flushing through a flushing and stripping head. The flushing function can be achieved without increasing the volume of the instrument, thereby achieving better surgical effects and avoiding new wounds, thereby improving the patient's experience.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0020] A flushable endoscopic minimally invasive surgical instrument comprises a handle 1 and a long-axis tube body 2, one end of the handle 1 is connected to the long-axis tube body 2, an endoscope mechanism is arranged in the long-axis tube body 2, and the endoscope mechanism can move along the axial direction of the long-axis tube body 2. When in use, the endoscope mechanism is extended from the long-axis tube body 2, and when not in use, the endoscope mechanism is retracted into the long-axis tube body 2, which protects the endoscope mechanism from damage or scratches. A flushing and stripping device is also arranged in the long-axis tube body 2, and the flushing and stripping device comprises a flushing and stripping head 3 and a flushing tube 4, the flushing tube 4 is located in the long-axis tube body 2 and fixedly connected to the handle 1, and the flushing and stripping head 3 is provided with a flushing cavity, and the flushing One end of the tube 4 away from the handle 1 is connected to the flushing and stripping head 3 and is connected to the flushing cavity. The end of the flushing and stripping head 3 away from the flushing tube 4 is located outside the long-axis tube body 2. The end of the flushing and stripping head 3 away from the flushing tube 4 is provided with a flushing port 5 communicated with the flushing cavity. The wound is flushed through the flushing port 5 on the flushing and stripping head 3. The flushing function is added on the basis of the cutting function of the flushing and stripping head 3. During surgery, flushing can be performed directly through minimally invasive surgical instruments. Flushing is performed through the flushing and stripping head 3, and surgical stripping and flushing are combined into one. The flushing function can be achieved without increasing the volume of the instrument, thereby improving the surgical effect, avoiding the creation of new wounds, and improving the patient's experience.

[0021] Furthermore, the flushing and stripping head 3 includes a scraper body 6, a scraper 7 and a stripping knife 8. One end of the scraper body 6 is connected to the flushing tube 4, and the other end is connected to the scraper 7 in an L shape. The end of the scraper 7 away from the scraper body 6 is connected to the stripping knife 8, and the end of the stripping knife 8 away from the scraper 7 is provided with a cutting edge. Both sides of the scraper 7 are blunt. The flushing port 5 is opened at the top of the scraper 7. The width of the scraper 7 is greater than the width of the stripping knife 8. The stripping knife 8 is connected to the middle of the scraper 7. During the operation, the tissue is cut by the stripping knife 8 on the flushing and stripping head 3. The two sides of the stripping knife 8 are blunt, and its head is a cutting edge to avoid the situation where the two sides of the stripping knife 8 contact with the tissue and cause trauma. At the same time, when it is necessary to clean blood stains or scrape off the cut tissue, the two sides of the scraper 7 are used to clean the tissue and blood stains. Since the scraper has a blunt edge, new trauma to the patient can be avoided, reducing the patient's surgical pain.

[0022] Furthermore, a connector 9 is fixed to one end of the handle 1 away from the long-axis tube body 2, and the endoscope mechanism includes an endoscopic probe 10, a wiring tube body 11 and a sliding cap 12. The wiring tube body 11 is slidably inserted into the handle 1 and the connector 9, and the sliding cap 12 is slidably sleeved on the connector 9. One end of the wiring tube body 11 is connected to the middle part of the sliding cap 12, and the other end is provided with the endoscopic probe 10. The sliding cap 12 is used to drive the endoscopic probe 10 to extend out of the long-axis tube body 2 or retract into the long-axis tube body 2. The connector 9 is provided with an external thread, and the sliding cap 12 is provided with an internal thread. The sliding cap 12 is connected to the connector 9 by threads. The endoscopic probe 10 is connected to a wire head and wired through a wiring tube body 11, which protects the line. The sliding cap 12 is rotated outward or inward along the connector 9 to move along the axis of the connector 9, thereby driving the endoscopic probe 10 to move in the long-axis tube body 2 through the wiring tube body 11, so that the endoscopic probe 10 can be extended out of the long-axis tube body 2 or retracted into the long-axis tube body 2 as needed, thereby protecting the endoscopic probe 10.

[0023] Furthermore, the handle 1 includes a finger clamping portion 13 and a palm clamping portion 14. One end of the finger clamping portion 13 is connected to the long axis tube body 2, and the other end is connected to the palm clamping portion 14 by an arc transition. The palm clamping portion 14 is provided with a concave arc surface structure, which is convenient for the palm to hold the handle 1 to prevent sliding from affecting the surgical process. The finger clamping portion 13 is provided with anti-slip grooves, which increase the friction between the fingers and the finger clamping portion 13 through the anti-slip grooves, further preventing sliding from affecting the surgical process.

[0024] The finger gripping portion 13 is provided with a water inlet pipe 15 , which is connected to the flushing pipe 4 , and is connected to an external water source pipe through the water inlet pipe 15 , and is sprayed through the flushing pipe 4 and the flushing port 5 to clean the cut part.
