Description

Technical Field

[0001] The present application relates to the field of hernia forceps, and in particular to a novel negative pressure hernia forceps. Background Art

[0002] Hernia forceps, also known as forceps-type hernia needles or abdominal wall suture forceps, consist of a handle and a forceps body. Medical staff can insert the hernia forceps into the avascular area of ​​the abdominal wall to puncture into the abdominal cavity. After the hernia forceps are removed, only a small pinhole is left in the abdominal wall of the human body, which does not need to be sutured and will not bleed. The length of the needle tube of the hernia forceps can meet the distance for pelvic surgery in the human body, thus reducing the increase in incisions. If necessary, medical staff can operate the hernia forceps to puncture other parts for surgical operations.

[0003] However, the existing hernia forceps are not conducive to entering the patient's abdominal cavity due to the shape and structure of the front end forceps. At the same time, during the surgical operation, due to the flexible movement of human tissue, the puncture process is prone to deviation, and even affects the progress of the operation.

[0023] As the instruction manual Figure 1-4 As shown: a new type of negative pressure hernia forceps, including: a handle 210, a push rod 120, a needle rod 220, a negative pressure connecting part 300, a micro air compressor 320, a vent 230, and a clamping part 130; the needle rod 220 is installed at the top of the handle 210; the push rod 120 passes through the inside of the handle 210 and is sleeved inside the needle rod 220; the negative pressure connecting part 300 is arranged on the bottom side of the needle rod 220, and the micro air compressor 320 is connected to the negative pressure connecting part 300; the vent 230 is arranged on the top side of the needle rod 220, when the vent 230 is facing the needle rod 220 side with negative pressure, the vent 230 can absorb human tissue on the outside side; the clamping part 130 is arranged at the top of the push rod 120, during the operation, the clamping part 130 is tightly connected to the top of the push rod 120, and the medical staff operates the push rod 120 to push out / retract, driving the clamping part 130 to extend / retract at the top of the needle rod 220.

[0024] A novel negative pressure hernia forceps working principle: when the clamping part 130 extends from the top of the needle rod 220, the clamping part 130 is in an open state, and then the clamping part 130 retracts from the top of the needle rod 220, and the clamping part 130 gradually closes to clamp the suture needle, suture or a small amount of human tissue. When the clamping part 130 closes and clamps a small amount of human tissue, it can assist in exposing and separating the surgical site. When the clamping part 130 shrinks in the push rod 120, the bevel needle tip formed by the needle at the top of the push rod 120 is convenient for penetrating human tissue; the micro air compressor 320 draws away the air at one end of the vent 230 to form a negative pressure. At this time, the other end of the vent 230 tightly absorbs the surrounding human tissue, and medical staff can operate the needle rod 220 of the hernia clamp to puncture the human tissue.

[0025] In this embodiment, the clamping head structure and its transmission control are used to clamp suture needles, sutures and other human tissues and items required for surgery that need to be clamped during surgery. It can also be used to deliver suture needles and sutures into the abdominal cavity, and can also take suture needles and sutures out of the abdominal cavity, thereby improving the convenience of abdominal surgery. The vents tightly absorb the mucous membrane of human tissue, making it in close contact with the outer periphery of the top of the needle rod, reducing the flexible movement of human tissue at the corresponding position, and making it convenient for the needle at the front end of the needle rod to pierce human tissue during abdominal surgery.

[0026] Specifically, a push ring 110 is provided at the bottom end of the push rod 120, and a fixing ring 215 is provided on the side of the handle 210. The thumb of the medical staff can pass through the push ring 110 to push out / retract the push rod 120, and the fingers can pass through the fixing ring 215 to fix the handle 210. The setting of the push ring 110 and the handle 210 facilitates the medical staff to operate the hernia forceps during surgery.

[0027] Specifically, the handle 210 is provided with an exhaust button 330 and an inflation button 335, and the exhaust button 330 and the inflation button 335 are communicated with the micro air compressor 320 to realize the control of the working state of the micro air compressor 320. Medical staff control the exhaust / inflation working state of the micro air compressor 320 through the exhaust button 330 and the inflation button 335.

[0028] Specifically, the negative pressure connection part 300 and the micro air compressor 320 are connected through the negative pressure tube 310; the needle rod 220 is provided with a needle rod negative pressure cavity top 232 and a push rod cavity wall 125, and the outer wall of the needle rod 220 and the needle rod negative pressure cavity top 232 and the push rod cavity wall 125 constitute a needle rod negative pressure cavity 231; the push rod 120 and the clamping part 130 can be accommodated in the push rod cavity wall 125.

[0029] Specifically, the clamping portion 130 includes: a first clamping portion 131, a second clamping portion 132, and a clamping bottom end 133; the first clamping portion 131 and the second clamping portion 132 are arranged at the top of the clamping bottom end 133, and the bottom of the clamping bottom end 133 is installed at the top of the push rod 120; the clamping bottom end 133 of the clamping portion 130 is made of tough material, and in the absence of external space constraints, the first clamping portion 131 and the second clamping portion 132 are opened at a certain angle. When the push rod 120 pulls the clamping bottom end 133 into the push rod cavity wall 125, the angle between the first clamping portion 131 and the second clamping portion 132 is reduced, and the clamping portion 130 gradually closes to clamp the suture needle, suture or human tissue, or other surgical items.

[0030] Specifically, the needle rod 220 is detachably mounted on the top of the handle 210 , so that medical personnel can remove the needle rod 220 from the handle 210 , thereby cleaning and disinfecting the needle rod 220 and the inside of the handle 210 .

[0031] Specifically, the micro air compressor 320 is any type of a micro piston compressor, a micro screw compressor, or a micro vane compressor.

[0032] Specifically, the bottom end 133 of the chuck is made of any one of silicone rubber, polyurethane, medical-grade polyethylene, polymer materials, and composite materials, and has a certain elasticity. If there is no external restraint, it will automatically restore the initial design shape.
