Description

Technical Field

[0001] The present invention relates to the technical field of laparoscopic puncture instruments, and in particular to a protective device for a laparoscopic puncture instrument and a laparoscopic puncture instrument. Background Art

[0002] At present, more and more surgeries can be completed with the help of laparoscopes. Laparoscopic puncture devices provide instrument channels for minimally invasive abdominal and pelvic surgeries. Laparoscopic puncture devices are suitable for various minimally invasive surgical operations. Laparoscopic puncture devices are mainly composed of a puncture sheath and a puncture needle. The surgeon first puts the puncture needle on the puncture sheath, then applies a certain force to the tail of the puncture device, uses the sharp tip of the puncture needle to pierce the abdominal wall to allow the entire puncture device to enter the abdominal cavity, and then pulls out the puncture needle, leaving the puncture sheath as a surgical channel.

[0003] The disposable laparoscopic puncture core is transparent and conical, and adopts a knifeless blunt separation method, which replaces cutting tissue with separating tissue. When the puncture core enters the abdominal wall, the puncture core pushes the tissue and blood vessels along the tissue fibers, minimizing the damage to the abdominal wall and blood vessels. Compared with the puncture core with a knife, it can reduce fascia damage by about 40% and reduce the formation of puncture hole hernia by more than 80%. The whole process of abdominal wall puncture can be directly controlled through the endoscope to avoid damaging the abdominal cavity tissue, save operation time and reduce operation pain. The problem of the existing technology is that the laparoscopic puncture core has no puncture distance during use. The laparoscopic puncture device has no positioning function and is operated entirely by the doctor's experience, which may easily lead to the phenomenon that the laparoscopic puncture device penetrates too far and damages human tissue. In addition, it does not have the function of fixing the puncture rod. During operation, if the puncture rod is not stably fixed in the inner cavity of the transparent catheter, the puncture rod will move. In severe cases, it will directly retreat into the inner cavity of the transparent catheter, causing the transparent catheter to directly contact human tissue, causing pain to the patient. At the same time, the existing laparoscopic puncture device placement instrument does not have the function of disinfection and needs to be disinfected again with a specific disinfection tool before use, wasting operation time. Summary of the invention

[0038] Working principle: First, the user rotates the threaded protective cover 2 to separate the threaded protective cover 2 from the pretreatment protective shell 1, and the threaded protective cover 2 drives the flexible rubber block 6 to separate from the inner cavity of the pretreatment protective shell 1, and takes the puncture device body 7 out of the inner cavity of the pretreatment protective shell 1, and the puncture rod 9 is separated from the inner cavity of the disinfection sleeve 4, and the alcohol disinfection cotton 5 performs pretreatment and disinfection on the puncture rod 9, which does not need to be disinfected again when used. The user rotates the handheld adjustment rotating block 1205, and the handheld adjustment rotating block 1205 drives the threaded rod 1203 to rotate in the inner cavity of the threaded hole 1204, and the threaded rod 1203 moves and drives the bearing 1202 to rotate and move synchronously, and the bearing 1202 drives the positioning ring plate 1201 to move, thereby realizing the adjustment of the positioning ring plate 120 1 is used for positioning puncture. Before use, the user controls the movement of the moving ring 1302, and the moving ring 1302 drives the threaded clamping ring 1303 to insert into the thread groove 1304, and rotates the moving ring 1302, so that the moving ring 1302 drives the threaded clamping ring 1303 to be threadedly connected with the thread groove 1304, so that the moving ring 1302 conflicts with the limiting ring 1301. Since the limiting ring 1301 is fixedly connected with the puncture rod handle 8, the purpose of fixing the puncture rod handle 8 and the puncture rod 9 is achieved, the stability of the puncture rod 9 during the puncture process is improved, and the transparent catheter 11 is prevented from directly contacting with human tissue and causing pain to the patient. After the puncture is completed, the puncture rod 9 is pulled out, and the doctor performs minimally invasive surgery.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
