Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a laparoscopic separation forceps with a suction function. Background Art

[0002] Separation forceps is an instrument used to separate tissues and organs, mainly used in minimally invasive surgery. During surgery, separation forceps are needed to separate the lesion tissue from the normal tissue. During the separation process, blood and flesh tissue will produce bleeding or exudate, which will cause great damage to the organs. It is necessary to use an aspirator to suck out the bleeding or exudate. In this way, secondary operations of separation and suction are required during the surgery, which causes certain pain to the patient.

[0003] In order to solve the above problems, Chinese patent CN215874837U discloses a medical negative pressure tissue separation forceps, including a left forceps body, a right forceps body and a connecting shaft, wherein the left forceps body and the right forceps body are connected through the connecting shaft, the lower end outer surface of the connecting shaft is covered with a fixing nut, the left end outer surface of the left forceps body is provided with a suction tube, the right end outer surface of the suction tube is fixedly installed with a connecting ring, the front end right side of the left forceps body is provided with a handle ring, the outer surface of the handle ring is covered with a rubber sleeve, the left end outer surface of the left forceps body is provided with a card slot, the front end side outer surface of the left forceps body is provided with a through hole, the front end outer surface of the left forceps body is connected with a forceps head, the right end outer surface of the forceps head is provided with a card bolt, the outer surface of the left forceps body is covered with a carbon steel layer, and the outer surface of the carbon steel layer is covered with an electroplating layer. The utility model is convenient for increasing the functionality of the negative pressure tissue separation forceps, and can improve the use effect of the separation forceps, and is practical.

[0004] When the utility model is used, bleeding or exudate may occur at the separation site of the human body, and the blood and flesh tissue mixed in the bleeding or exudate may be mistakenly sucked into the suction tube, causing the suction tube to be blocked, making it impossible for the separation forceps to use the suction function. Utility Model Content

[0005] The utility model provides a laparoscopic separation forceps with a suction function, which prevents blood and flesh tissue in bleeding or exudate from being sucked in by mistake, thereby preventing the suction tube from being blocked.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A laparoscopic separation forceps with a suction function comprises: a movable forceps handle and a fixed forceps handle, the movable forceps handle is hinged with the fixed forceps handle; a hollow forceps rod is fixedly connected to the upper part of the fixed forceps handle, a forceps clamp and a blood drainage hole are provided at one end of the hollow forceps rod away from the fixed forceps handle, the blood drainage hole is located behind the forceps clamp, the forceps clamp comprises a fixed forceps clamp and a movable forceps clamp, the fixed forceps clamp is fixedly connected to the hollow forceps rod, the movable forceps clamp is hinged with the hollow forceps rod, and the movable forceps clamp is fixedly connected to the movable forceps handle through a traction linkage assembly; a negative pressure channel is provided in the fixed forceps handle, a connecting hole is provided at the bottom end of the negative pressure channel, the connecting hole is connected with the negative pressure assembly, a blocking part is provided at the upper part of the negative pressure channel, the blocking part comprises a button, a support rod, a blocking block and an elastic member, the button is arranged on the outer side of the fixed forceps handle, one end of the support rod is fixedly connected to the button, the other end of the support rod is fixedly connected to the blocking block, an elastic member is provided between the blocking block and the fixed forceps handle, and the blocking part is slidably matched with the fixed forceps handle; an ultrasonic oscillator is fixedly connected to the middle part of the hollow forceps rod, and the button is also used as a button switch to turn on and off the ultrasonic oscillator.

[0008] The basic scheme principles and beneficial effects are as follows:

[0009] When using the separation forceps, first connect the connection hole of the negative pressure channel at the bottom of the fixed forceps handle to the negative pressure component, so that the subsequent bleeding or exudate can be collected by the negative pressure component. Then hold the two forceps handles and manually align the clamps with the blood and flesh tissue that needs surgery, press the movable forceps handle, and the traction linkage component hinged to the movable forceps handle drives the movable clamp to move toward the fixed clamp, so that the two clamps clamp the blood and flesh tissue, thereby separating or lifting the blood and flesh tissue.

[0010] When bleeding or exudate flows out of flesh and blood tissue and blocks the line of sight, the button located on the outside of the fixed clamp handle is pressed, and the button drives the support rod to apply pressure to the elastic part in the blocking part. The elastic part is compressed, and the blocking block is removed from the negative pressure channel. The negative pressure channel is connected to the hollow clamp rod, and under the attraction of negative pressure, the bleeding or exudate enters the hollow clamp rod through the blood inlet hole at one end of the hollow clamp rod, flows out from the connecting hole through the negative pressure channel, and is collected by the negative pressure component, thereby restoring the line of sight blocked by the bleeding or exudate.

[0011] When the button is pressed, the power supply of the ultrasonic oscillator is connected, the ultrasonic oscillator is turned on, and the high-frequency vibration of the ultrasonic wave is used to act on the tiny blood and flesh tissues accidentally inhaled into the pipeline, causing them to oscillate and relax in the pipeline, thereby eliminating the hidden danger of pipeline blockage.

[0012] In summary, the separation position of the human body will produce bleeding or exudate during the separation process, and the blood and flesh tissue mixed in the bleeding or exudate may be mistakenly sucked into the suction tube, causing the suction tube to be blocked, thereby improving the situation in which the separation forceps cannot use the suction function.

[0013] Furthermore, both the fixed clamp and the movable clamp are provided with clamping teeth, and the clamping teeth can mesh with each other.

[0014] Beneficial effect: The clamp with teeth can grasp the flesh and blood tissue more firmly, preventing the separation forceps from slipping during surgery.

[0015] Furthermore, the fixed clamp handle and the movable clamp handle are scissor-shaped, and circular holes are provided at the bottom of the two clamp handles.

[0016] Good for tissue: The round holes at the bottom of the two pliers handles make it easier for users to grip and prevent the separation pliers from slipping out of their hands.

[0017] Furthermore, the traction linkage assembly includes a traction rope and a pulley fixed on the fixed clamp handle, one end of the traction rope is fixedly connected to the movable clamp, and the other end of the traction rope passes around the pulley and is fixedly connected to the movable clamp handle.

[0018] Beneficial effect: The movable clamp handle drives the movable clamp through the traction rope, so that the movable clamp handle can control the movable clamp more conveniently and the movable clamp can react more quickly.

[0019] Further, the push button switch electrically connects the power supply and the ultrasonic oscillator.

[0020] Beneficial effect: When the suction tube is blocked, the ultrasonic oscillator can be quickly turned on by pressing the button switch, so that the fine blood and flesh tissue blocked in the pipe can be vibrated and loosened, thus clearing the pipe. The button switch, power supply and ultrasonic oscillator are connected in series, and the simple electrical connection method makes the ultrasonic oscillator more convenient to open and close.

[0021] Furthermore, both the movable clamp handle and the fixed clamp handle are wrapped with an anti-slip layer.

[0022] Beneficial effect: The anti-skid layer increases the friction of the handle of the separation pliers, which can prevent the separation pliers from slipping out of the hand.

[0023] Furthermore, the fixed clamp handle and the movable clamp handle are hinged via a rotating shaft, a torsion spring is arranged between the fixed clamp handle and the movable clamp handle, and two swing arms of the torsion spring are respectively fixed on the movable clamp handle and the fixed clamp handle.

[0024] Beneficial effect: the torsion spring forms a certain pressing resistance, so that the operator can better control the strength when using the separation pliers, and the force of the torsion spring itself can automatically reset the separation pliers, eliminating the need for the operator to exert extra force.

[0025] Furthermore, a rod seat is provided on the upper portion of the fixed clamp handle, a rotating handle is mounted on the rod seat, a connecting cap is fixed to the front end of the rotating handle, and the hollow clamp rod is fixed on the connecting cap.

[0026] Beneficial effects: The rotating handle can drive the hollow clamp rod to rotate, and the hollow clamp rod drives the clamp to rotate. When in use, the user can adjust the direction of the clamp according to needs, which is more convenient for the user to perform surgery on flesh and blood tissues in different positions.

[0027] Furthermore, a buckle is provided between the button of the blocking part and the fixed clamp handle.

[0028] Beneficial effect: The buckle prevents the button from automatically popping up after being pressed down, so that the negative pressure channel and the ultrasonic oscillator can be opened for a long time, making it easier to use the separation forceps.

[0029] Furthermore, a rubber ring is provided at the connection portion between the blocking portion and the negative pressure channel.

[0030] Beneficial effect: The rubber ring prevents the possibility of blood or liquid seepage from the connection part between the blocking part and the negative pressure channel when the blocking part is pressed down and the negative pressure channel is opened. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed button 5 is welded to one end of the rod 122, and a fixed blocking block 123 is welded to the other end of the support rod 122. An elastic member 121 is provided between the blocking block 123 and the fixed clamp handle 1, and the blocking portion 12 is slidably matched with the fixed clamp handle 1; an ultrasonic oscillator 9 is fixed with a screw in the middle part of the hollow clamp rod 3, and the button 5 is also used as a button switch to turn on and off the ultrasonic oscillator 9, specifically: the button 5, the power supply and the ultrasonic oscillator 9 are a series circuit, the positive pole of the ultrasonic oscillator 9 is electrically connected to the first conductive wire 92, and the first conductive wire 92 is installed on the button 5, the negative pole of the ultrasonic oscillator 9 is connected to the negative pole of the power supply 91, and the positive pole of the power supply 91 is electrically connected to the second conductive wire 93, and the second conductive wire 92 is installed on the fixed clamp handle 1. When the button 5 is pressed or released, the first conductive wire 92 and the second conductive wire 93 are turned on or off, so that the ultrasonic oscillator 9 can be turned on and off, and the simple electrical connection method makes the opening and closing of the ultrasonic oscillator more convenient.

[0040] Specifically, the fixed clamp handle 1 and the movable clamp handle 2 are scissor-shaped and are both wrapped with an anti-skid layer. The bottom of the two clamp handles are provided with a circular hole. Such a design can increase the friction of the separation clamp handle, facilitate the user's grip, and prevent the separation clamp from slipping. A rotating device 8 is welded and fixed on the upper part of the fixed clamp handle 1. The rotating device 8 includes a rod seat 81. The bearing on the rod seat 81 is connected to a rotating handle 82. The front end of the rotating handle 82 is welded and fixed with a connecting cap 83, and the hollow clamp rod 3 is welded and fixed on the connecting cap 83. The rotating handle 82 drives the hollow clamp rod 3 to rotate, and the hollow clamp rod 3 drives the clamp 4 to rotate.
