Novel vertebral functional forceps
[01] The utility model relates to a medical device, in particular to a novel vertebral functional forceps.
[02] Osteoporosis is a systemic and metabolic disease of the skeletal system, with pathological features of decreased bone mass, damaged bone microstructure, increased bone fragility and decreased bone strength. Vertebral osteoporotic compression fracture is the most common form of fracture caused by osteoporosis. With the aging of China's population, senile osteoporosis and its fractures have become an important factor to reduce the living quality of the elderly. In addition, the incidence of tumor in the elderly is relatively high, and pathological vertebral compression fractures caused by some tumor metastases to the vertebral body also occur from time to time. When the problem of vertebral compression fracture is found, we need to identify whether it is vertebral osteoporotic compression fracture or pathological vertebral compression fracture, so as to take different treatment plans.
[03] For pathological vertebral compression fractures, pathological biopsy is the gold standard to determine whether tumor metastasis. Conventional aspiration biopsy usually requires repeated introduction of the puncture needle into the lesion. However, due to the complex anatomical structure of vertebral body and abundant blood supply of tumor lesions, aspiration biopsy can easily lead to complications such as pneumothorax, hematoma, nerve root damage and implantation metastasis. Although reducing the number of needle biopsy can reduce the occurrence of complications, it may also reduce the accuracy of biopsy, leading to the inability to determine the real cause of fracture. Therefore, at present, there is a lack of an instrument that can not only reduce the complications during sampling, but also obtain materials with high efficiency and high quality.
[04] The purpose of the utility model is to provide a new type of vertebral functional forceps to solve the problems of pneumothorax, hematoma, nerve root damage and other complications easily caused by the existing needle biopsy method.
[05] The utility model achieves the purpose as follows:
[06] A new type of vertebral functional forceps is comprised of a forceps jaw, a forceps rod and a handle. Wherein, the forceps jaw is composed of a hinged fixed forceps holder and a movable holder; the forceps rod is a hollow forceps tube with a pull rod inside; the handle is composed of a hinged fixed handle and a movable handle.
[07] The front part of the fixed forceps holder is the forceps mouth and the back part is the connecting part with a hollow tube cavity whose end is connected with one end of the forceps tube; the lower end of the fixed handle is the handheld part and the upper end is the connecting part with a hollow tube cavity, which is connected with the other end of the forceps tube; the pull rod is arranged through the hollow tube cavities of the fixed forceps holder, the forceps tube and the fixed handle, and its end is connected with the upper end of the movable handle, and its front end is hinged with the rear end of the movable forceps holder.
[08] A new type of vertebral functional forceps is provided with a groove on the occlusal surface of the forceps mouth of the fixed and movable forceps holders, designed for grasping and containing tissue material.
[09] For the new type of vertebral functional forceps, on both sides of the hinged shaft of the fixed handle and the movable handle, a first limit stop and a second limit stop are arranged on the fixed handle. Wherein, the height of the first limit stop makes the occlusal surface completely closed when the fixed forceps holder and the movable forceps holder are engaged; the height of the second limit stop makes the maximum opening angle of the occlusal surface to be 90 degrees, when the fixed forceps holder and the movable forceps holder are opened.
[010] The utility model has the advantages as follows:
[011] In the operation of minimally invasive surgery (percutaneous vertebroplasty) for the treatment of vertebral osteolytic bone tumor and vertebral osteoporotic compression fracture, the functional forceps of the utility model can smoothly pass through the working cannula used in the operation process, and take vertebral body during minimally invasive operation.
[012] In the internal operation of the vertebral body, the opened forceps jaw can rotate 3600to clamp the tissues in all directions, so that the pathological material can be taken more fully to obtain pathological materials with higher quality.
[013] Moreover, the pathological sampling with functional forceps is carried out in the working cannula so as to avoid the related complications such as injury of spinal cord, blood vessel and peripheral nerve and implantation metastasis caused by repeated puncture.
[014] In addition, the new type creates a cavity while obtaining the vertebral body specimen. The bone cement is first filled into the small cavity made by the functional forceps. With push, the bone cement slowly disperses from the cavity to the surrounding and evenly distributes.
[015] The artificial cavity can reduce the internal pressure of vertebral body to reduce the injection pressure of bone cement and make its dispersion distribution more uniform, so as to effectively reduce the serious complications such as bone cement leakage.

[018] Figure. 3 is the structural diagram of the handle of the utility model.
[019] Figure. 4 is the structural diagram of the forceps mouth of the fixed forceps and the movable forceps of the utility model.
[020] In figures, 1- fixed handle, 2- movable handle, 3- pull rod, 4- bold section, - contraction section, 6- fixed forceps holder, 7- movable forceps holder, 8- occlusal surface, 9-groove,10- the first limit stop, 11- the second limit stop.
[021] As shown in Figure 1, a new type of vertebral functional forceps is comprised of a forceps jaw, a forceps rod and a handle.
[022] Wherein, the angle between the handle and the forceps rod is 90°~180°, preferably 120°~150°. The forceps rod is a hollow forceps tube with a pull rod (3) inside, and the forceps tube can be a hollow tubular body with the same thickness at the front and the back. For the convenience of operation and observation, it can also with a second half of bold section (4) and a first half of finer contraction section (5), as shown in Figure 1. The forceps jaw is composed of a hinged fixed forceps holder and a movable holder; he handle is composed of a hinged fixed handle (6) and a movable handle (7), as shown in Fig.2.
[023] The front part of the fixed forceps holder (6) is the forceps mouth and the back part is a tubular body with a hollow tube cavity whose end is connected with the front end of the forceps tube. A groove (9) similar to a triangular vertebral body is arranged on the occlusal surface (8) of the forceps mouth of the fixed forceps (6) (and the forceps mouth of the movable forceps (7)), which is used to grasp and contain tissue materials.
[024] The front end of the pull rod (3) extends into the tubular body of the fixed forceps (6) and is hinged with the rear end of the movable forceps (7).
[025] As shown in Figure 3, the structure of the handle part is composed of a shaped movable handle (2) and a fixed handle (1), which are hinged and fixed at the bending point.
[026] The lower end of the fixed handle (1) is the handheld part and the upper end is provided with a hollow tube cavity, which is connected with the end of the forceps tube. The back end of pull rod (3) extends into the upper tubular body of the fixed handle (1) and is hinged with the upper end of the movable handle (2).
[027] According to the above design, the relatively open and close to the fixed forceps (6) of movable forceps (7) can be achieved by controlling the movable handle (2).
[028] Furthermore, as shown in Figure 3, the first limit stop (10) and the second limit stop (11) are respectively arranged on both sides of the hinged shaft on the fixed handle (1). The first limit stop (10) makes the movable forceps (7) and the fixed forceps (6) completely close when the fixed handle (1) and the movable handle (2) are closed, and the second limit stop (11) enables the maximum opening angle of the movable forceps (7) and the fixed forceps (6) to reach 900 when the fixed handle (1) and the movable handle (2) are opened.
[029] The working length (i.e. the horizontal distance between the top end of the forceps and the end of the handle) of the utility model is generally 190 mm ~ 200 mm.
[030] The hardness of the material at the forceps jaw is more than 45HRC, and the outer surface of it should be smooth, straight, symmetrical, without sharp edge, sand hole, crack, incomplete and other defects. The clamping force at the forceps jaw is not less than 20N.
[031] The use method of the utility model is that during the operation, inserting the new model into the used working cannula to make the forceps jaw into the vertebral tissue for sampling. During the internal operation of the vertebral body, the tissues in all directions of the vertebral body can be clamped according to the need to obtain pathological materials.
