Description

Technical Field

[0001] The present invention relates to the technical field of laparoscopic puncture, and more specifically, to a filtering type laparoscopic trocar. Background Art

[0002] A laparoscopic trocar is a device for providing an instrument channel for minimally invasive abdominal and pelvic surgeries. It is a surgical instrument that cooperates with minimally invasive devices to provide an instrument channel for minimally invasive abdominal and pelvic surgeries and can be used in various minimally invasive surgical procedures. The laparoscopic trocar has an ergonomic holding handle, which is comfortable to hold and has excellent puncture controllability. However, the existing laparoscopic trocars have the following deficiencies: when the laparoscopic trocar punctures a patient, the trocar will expel the gas in the patient's body after piercing into the patient's body. And when the trocar is removed from the patient's body, it is easy to carry germs out and cause pollution to the surrounding area. At the same time, during the process of the trocar piercing into the patient's body, it is exposed to the air and is easily contaminated to a certain extent, reducing the cleanliness of the trocar when piercing into the patient's body, resulting in infection at the puncture site of the patient and reducing the safety of the patient during puncture. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a filtering type laparoscopic trocar, the structure of which includes a puncture blade, an auxiliary device, and a socket seat. The puncture blade vertically penetrates through a filter box and a disinfection mechanism provided on the auxiliary device, and the lower end of the filter box is inserted and installed inside the socket seat. Inside the filter box, there are a positioning ring, a filter cylinder, and a filter plate. The positioning ring communicates with the top of the filter box, and the upper end of the filter cylinder is inserted and installed inside the positioning ring. The sleeve pipe in the middle of the upper end of the filter plate is sleeved and installed at the lower end of the filter cylinder. The puncture blade vertically penetrates through the positioning ring, the filter cylinder, and the sleeve pipe. The filter cylinder is located at the center position inside the filter box and the filter plate is laid flat at the bottom of the filter box, so as to comprehensively filter the gas discharged when the puncture blade pierces into the patient's body.

[0004] As a further improvement of the present invention, a wiping mechanism is provided at the lower end of the sleeve pipe. The wiping mechanism includes a rotating pipe, rotating pieces, a sponge ring, and a clamping rod. The rotating pipe is inserted and installed inside the sleeve pipe, and rotating pieces are provided on both sides of the lower end of the rotating pipe. The sponge ring is fitted and installed inside the rotating pipe. A clamping rod is provided at the top of the rotating pipe, and the clamping rod is clamped inside a clamping rotating groove at the upper end of the sleeve pipe and rotates to fix the rotating pipe inside the sleeve pipe. There are two clamping rods and two clamping rotating grooves, and the two clamping rotating grooves are embedded in the front side of the upper end of the sleeve pipe and are in a reverse state. After the two clamping rods are clamped inside the clamping rotating grooves, they rotate clockwise and are hidden inside the clamping rotating grooves for positioning, so as to clamp and fix the rotating pipe inside the sleeve pipe on the same axis.

[0005] As a further improvement of the present invention, a clamping mechanism is further provided inside the filter box. The clamping mechanism is composed of a spring tube sleeve, a pressing rod and a clamping piece. The spring tube sleeve is fixed on the inner wall of the lower end of the filter box, and the outer end of the pressing rod is elastically pressed inside the spring tube sleeve. A clamping piece is provided at the inner end of the pressing rod to clamp the outside of the sleeve pipe. There are two spring tube sleeves, pressing rods and clamping pieces, and they are symmetrically installed on both sides inside the filter box.

[0006] As a further improvement of the present invention, a telescopic hose and a suction cup are further provided at the lower end of the socket seat, and the inside of the telescopic hose is connected to the inside of the filter box in a through manner. The puncture blade penetrates through the centers of the socket seat, the telescopic hose and the suction cup. The airflow generated by the elastic expansion and contraction of the telescopic hose is discharged through the air outlet holes at the top of the filter box, so that the suction cup adsorbs on the patient's skin surface.

[0007] As a further improvement of the present invention, a disinfection mechanism is further provided at the top of the filter box. The disinfection mechanism is composed of a liquid storage tank and an outer sleeve. A liquid filling port is embedded at the upper end of the liquid storage tank, and the liquid storage tank is connected to the transmission groove inside the outer sleeve in a through manner. The lower end of the outer sleeve is installed in the middle of the top of the filter box, and an inner abutting block is provided inside the outer sleeve. There is a liquid outlet groove between the inner abutting block and the transmission groove, and a top spring and a pressure ball are arranged inside the liquid outlet groove. Under the elastic force applied by the top spring, the pressure ball moves by extrusion at the inner end of the liquid outlet groove. There are four inner abutting blocks, liquid outlet grooves, top springs and pressure balls, and they are distributed in four directions inside the outer sleeve. When the puncture blade penetrates into the inside of the outer sleeve, the puncture blade squeezes the pressure ball inward. At this time, a gap is generated between the pressure ball and the liquid outlet groove, so that the iodophor stored inside the liquid storage tank flows along the transmission groove to the inside of the liquid outlet groove and is discharged.

[0008] As a further improvement of the present invention, a support rod is further welded to the top of the outer sleeve. The puncture blade penetrates through the inside of the guide ring provided at the top of the support rod, and ball bearings are arranged inside the guide ring to assist the lifting of the puncture blade.

[0009] The beneficial effects of the present invention are as follows: 1. The filter cartridge is located at the central position inside the filter box and the filter plate is laid flat at the bottom of the filter box, so as to comprehensively filter the gas discharged by piercing the patient's body, avoiding the pollution caused by the gas carrying germs to the surrounding. The filter cartridge and the filter plate are connected by a plug-in method, and can be quickly removed from the filter box for cleaning, disinfection or replacement, ensuring that the filter cartridge and the filter plate can efficiently filter the gas; 2. After the two clamping rods are clamped inside the clamping rotating groove, they rotate clockwise and hide inside the clamping rotating groove for positioning, so as to clamp and fix the rotating tube inside the sleeve tube on the same axis. At this time, the sponge ring and the sleeve tube are on the same axis, which can wipe the surface of the puncture blade penetrating inside the sleeve tube, improve the cleanliness of the surface of the puncture blade after piercing and moving out of the patient's body, avoid medical staff from touching the germs on the surface of the puncture blade, and the overall wiping mechanism can be quickly disassembled and assembled from the lower end of the sleeve tube, which is convenient for later cleaning and disinfection work; 3. The puncture blade squeezes the pressure ball inward. At this time, a gap is generated between the pressure ball and the liquid outlet groove, so that the iodophor stored in the liquid storage tank flows along the transmission groove to the inside of the liquid outlet groove and is discharged, contacts the surface of the puncture blade, and disinfects the surface of the puncture blade. The puncture blade will rotate during the puncture process, so that the iodophor is covered on the whole surface of the puncture blade through the four distributed liquid outlet grooves, avoiding infection at the puncture site when the patient is punctured and ensuring the safety of the patient during puncture.

The wiping mechanism 214 includes a rotating pipe 2141, a rotating piece 2142, a sponge ring 2143, and an engaging rod 2144. The rotating pipe 2141 is inserted and installed inside the sleeve pipe 2131, and rotating pieces 2142 are provided on both sides of the lower end of the rotating pipe 2141. The sponge ring 2143 is fitted and installed inside the rotating pipe 2141. An engaging rod 2144 is provided at the top of the rotating pipe 2141, and the engaging rod 2144 is engaged inside the engaging rotation groove 1311 at the upper end of the sleeve pipe 2131 and rotates to fix the rotating pipe 2141 inside the sleeve pipe 2131.

[0021] As a further improvement of the present invention, a clamping mechanism 215 is further provided inside the filter box 21. The clamping mechanism 215 is composed of a spring tube sleeve 2151, a pressing rod 2152 and a clamping piece 2153. The spring tube sleeve 2151 is fixed on the inner wall of the lower end of the filter box 21, and the outer end of the pressing rod 2152 is elastically pressed inside the spring tube sleeve 2151. A clamping piece 2153 is provided at the inner end of the pressing rod 2152 to clamp the outer side of the sleeve connecting pipe 2131.

[0022] As a further improvement of the present invention, a telescopic hose 4 and a suction cup 5 are further provided at the lower end of the socket seat 3, and the inside of the telescopic hose 4 is connected to the inside of the filter box 21 in a through manner. The puncture blade 1 penetrates through the centers of the socket seat 3, the telescopic hose 4 and the suction cup 5.

[0023] As a further improvement of the present invention, a disinfection mechanism 22 is further provided at the top of the filter box 21. The disinfection mechanism 22 is composed of a liquid storage tank 221 and an outer sleeve pipe 222. A liquid filling port 2211 is embedded at the upper end of the liquid storage tank 221, and the liquid storage tank 221 is connected to a transmission groove 2221 inside the outer sleeve pipe 222 in a through manner. The lower end of the outer sleeve pipe 222 is installed at the middle of the top of the filter box 21, and an inner abutting block 2222 is provided inside the outer sleeve pipe 222. An outlet groove 2223 is provided between the inner abutting block 2222 and the transmission groove 2221, and a top spring 2224 and a pressing ball 2225 are arranged inside the outlet groove 2223. Under the elastic force applied by the top spring 2224, the pressing ball 2225 moves by extrusion at the inner end of the outlet groove 2223.

[0024] As a further improvement of the present invention, a support rod 23 is also welded to the top of the outer sleeve 222. The puncture blade 1 passes through the inside of a guide ring 24 provided at the top of the support rod 23. A ball is provided inside the guide ring 24 to assist the lifting of the puncture blade 1, ensuring that the puncture blade 1 is more smooth and stable when puncturing a patient. In the present invention, the suction cup 5 is placed at the position where the patient is to be punctured. Then, by pressing the socket 3, the telescopic hose 4 is contracted to discharge the gas from the air outlet hole at the top of the filter box 21, so that the suction cup 5 is vacuum adsorbed on the patient's skin surface, improving the effect of stably positioning the puncture blade 1 at the puncture position of the patient. Then, the puncture blade 1 is passed through the inside of the guide ring 24 and penetrates into the inside of the outer sleeve 222. At this time, the pressure ball 2225 inside the inner abutting block 2222 is extruded outwards, so that the iodophor in the liquid storage tank 221 is discharged from the liquid outlet groove 2223 and contacts the surface of the puncture blade 1 to disinfect and sterilize the surface of the puncture blade 1. Then, the puncture blade 1 continues to penetrate through the inside of the filter cylinder 212 and the sleeve 2131, and at the same time contacts the sponge ring 2143 to wipe off the excess iodophor and the iodophor is adsorbed inside the sponge ring 2143. Finally, the puncture work is carried out on the patient. During the puncture process, the gas discharged from the patient's body flows upwards and contacts the filter cylinder 212 and the filter plate 213. The filter cylinder 212 and the filter plate 213 filter the germs carried in the gas comprehensively. Finally, after the puncture is completed, the puncture blade 1 is pulled out from the patient's body, and the iodophor in the sponge ring 2143 is used again to wipe and disinfect the germs carried on the surface of the puncture blade 1.

[0025] In a preferred technical solution, the filter cylinder 212 is located at the central position inside the filter box 21 and the filter plate 213 is laid flat at the bottom of the filter box 21, so as to comprehensively filter the gas discharged when the puncture blade 1 pierces into the patient, avoiding the pollution caused by the gas carrying germs to the surroundings. The filter cylinder 212 and the filter plate 213 are connected by a plug-in method, and can be quickly removed from the inside of the filter box 21 for cleaning, disinfection or replacement, ensuring that the filter cylinder 212 and the filter plate 213 can filter the gas efficiently; A preferred technical solution is that there are two engaging rods 2144 and two engaging rotating grooves 1311. The two engaging rotating grooves 1311 are embedded in the front side of the upper end of the sleeve pipe 2131 and are in reverse states. After the two engaging rods 2144 are engaged in the engaging rotating grooves 1311, they rotate clockwise and are hidden inside the engaging rotating grooves 1311 for positioning. Thus, the rotating pipe 2141 is engaged and fixed inside the sleeve pipe 2131 on the same axis. At this time, the sponge ring 2143 and the sleeve pipe 2131 are on the same axis, and can wipe the surface of the puncture blade 1 penetrating inside the sleeve pipe 2131, improving the cleanliness of the surface of the puncture blade 1 when it is removed from the patient's body after puncture, avoiding medical staff from touching the germs on the surface of the puncture blade 1, and the wiping mechanism 214 as a whole can be quickly disassembled and assembled from the lower end of the sleeve pipe 2131, facilitating the later cleaning and disinfection work; A preferred technical solution is that there are two spring tube sleeves 2151, two extrusion rods 2152 and two clamping pieces 2153, and they are symmetrically installed on both sides inside the filter box 21. Under the elastic cooperation of the spring tube sleeve 2151 and the extrusion rod 2152, the two arc-shaped clamping pieces 2153 on both sides can elastically clamp the outer ends of the sleeve pipe 2131, thereby improving the firmness of the engaging connection between the filter cartridge 212 and the filter plate 213; A preferred technical solution is that the airflow generated by the elastic expansion and contraction of the telescopic hose 4 is discharged through the air outlet holes at the top of the filter box 21, so that the suction cup 5 adsorbs on the patient's skin surface, improving the effect of stably positioning the puncture blade 1 at the puncture position of the patient; A preferred technical solution is that there are four inner abutting blocks 2222, four liquid discharge grooves 2223, four top springs 2224 and four pressure balls 2225, and they are distributed in four directions on the inner side of the outer sleeve 222. When the puncture blade 1 penetrates into the outer sleeve 222, the puncture blade 1 squeezes the pressure ball 2225 inward. At this time, a gap is generated between the pressure ball 2225 and the liquid discharge groove 2223, so that the iodophor stored in the liquid storage tank 221 flows along the transmission groove 2221 into the liquid discharge groove 2223 and is discharged, contacting the surface of the puncture blade 1 and disinfecting the surface of the puncture blade 1. The puncture blade 1 will rotate during the puncture process, so that the iodophor is covered on the whole surface of the puncture blade 1 through the four distributed liquid discharge grooves 2223, avoiding infection at the puncture site when the patient is punctured and improving the safety of the patient during puncture. Using the technical solution of the present invention, or those skilled in the art inspired by the technical solution of the present invention to design similar technical solutions and achieving the above technical effects shall fall within the protection scope of the present invention.
