Description

Bendable nucleus pulposus forceps with liquid introduction function

technical field

The utility model relates to a nucleus pulposus forceps, in particular to a bendable nucleus pulposus forceps with the function of introducing liquid.

Background technique

In the treatment of lumbar disc herniation, nucleus pulposus surgery is required, and the nucleus pulposus tissue needs to be taken out with nucleus pulposus forceps. The head and the body of the nucleus pulposus forceps in the prior art are integrated. The working angle of this nucleus pulposus forceps is limited, and it is very difficult to clamp the nucleus pulposus tissue behind the vertebral body, and it is very easy to injure the spinal cord.

When performing nucleus pulposus surgery, it needs to be performed in a liquid environment, and the nucleus pulposus forceps in the prior art are mostly composed of inlays, forceps heads, clamps, connecting guide wires and handles. At present, there is no pulposus forceps with liquid introduction function. For nuclear forceps, it is necessary to introduce liquid through the liquid introduction tube separately during the operation.

Because the nucleus pulposus removal operation requires the doctor to be highly concentrated, otherwise the nerve may be injured due to a slight shaking of the doctor's hand. When using traditional nucleus pulposus forceps for surgery, because the handles of traditional nucleus pulposus forceps are straight, the doctor will feel soreness in the index finger and middle finger when holding the forceps for a long time, and the hanging state of the little finger will also affect the stability of the doctor's grip forceps .

Utility model content

The purpose of the utility model is to provide a bendable nucleus pulposus forceps with the function of liquid introduction, which has the function of liquid introduction, and the head of the forceps can be bent arbitrarily, so as to solve the problem that the traditional nucleus pulposus forceps has an operation dead angle, and has The advantage of being comfortable to use and enhancing the stability of the gripper.

The technical scheme of the utility model: a bendable nucleus pulposus forceps with the function of introducing liquid, including a fixed handle, a movable handle, a nucleus pulposus forceps sheath rod, a connecting seat, a wire drawing, a bendable deformation tube, a forceps head, and an upper forceps Clamp and lower jaw, the fixed handle and the movable handle are movably connected through the rotating shaft A, the fixed handle is fixedly connected with one end of the sheath rod of the nucleus pulposus forceps through the connecting seat, and the other end of the sheath rod of the nucleus pulposus forceps is connected to the forceps head through a bendable deformation tube Fixed connection, the clamp head is fixedly connected with the lower jaw, the lower jaw is movably connected with the upper jaw through the rotating shaft B, the bottom of the upper jaw is connected with one end of the wire drawn inside the sheath rod of the nucleus pulposus forceps, and the other end of the wire is connected with the The movable handle is connected; a flushing channel is provided in the sheath rod of the nucleus pulposus forceps, and a flushing channel connection port is provided on the side of the connecting seat.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, the flushing channel connection port is provided with a flushing channel cap, and the flushing channel connection port and the flushing channel cap are connected by threads. Since the tools used for surgery must be strictly sterilized, a flushing channel cap is provided to prevent bacteria from entering the flushing channel.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, the flushing channel cap is cylindrical, and the outer wall of the flushing channel cap is provided with anti-slip protrusions. The purpose of setting the anti-slip protrusion is to increase the friction force between the hand and the flushing channel cap, so that the doctor can easily unscrew it.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, the bendable deformation tube is made of memory alloy. The purpose of adopting the memory alloy is to ensure that the bendable deformable tube can keep the angle when it is bent to a certain angle.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, a scale is provided on the outer wall of the end of the sheath rod of the nucleus pulposus forceps connected to the connecting seat. Setting the scale can reduce the risk of surgery and increase the accuracy of surgery.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, grooves are arranged on the outside of the movable handle. The groove on the outside of the movable handle is designed according to the shape of the human hand, which can accommodate the index finger and middle finger, which solves the problem of soreness in the index finger and middle finger caused by long-term use of traditional nucleus pulposus forceps without grooves.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, the bottom of the movable handle is provided with a finger bar. The purpose of setting the finger stop lever is to support the little finger, so as to prevent hand shaking caused by the little finger hanging in the air for a long time. In addition, the addition of the finger support bar is also conducive to the release of hand strength when the doctor holds the forceps in reverse.

In the aforementioned bendable nucleus pulposus forceps with the function of introducing liquid, both the upper jaw and the lower jaw are provided with locking teeth. The purpose of setting the locking teeth is to prevent the nucleus pulposus tissue from falling off when the nucleus pulposus forceps clamps the nucleus pulposus tissue.

Compared with the prior art, the utility model is provided with a bendable deformation tube, so that the forceps head can be bent into a required angle at will, which completely solves the problem of the dead angle of operation in the traditional nucleus pulposus forceps. Since the flushing channel is set, the liquid can be introduced at any time, and there is no need to set a catheter separately. Because there is a groove on the outside of the movable handle, the index finger and middle finger can be placed in the groove, which can effectively prevent finger fatigue. In addition, because there is a finger stop bar at the bottom of the movable handle, it can effectively prevent hand shaking caused by the little finger hanging in the air. Can effectively reduce the risk of surgery. .
