Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a surgical tool. Background Technology

[0002] Currently, with the continuous development of medical technology, nucleus pulposus clamps are gradually being applied in orthopedic clinical surgery, and have a crucial impact on the surgical outcome.

[0003] For example, during lumbar disc herniation surgery, a puncture needle can be inserted to the designated location (the herniated disc), and then a sleeve can be inserted along the puncture needle to create a channel. Then, a nucleus pulposus clamp can be inserted into the channel to partially or completely remove the diseased tissue (i.e., the herniated nucleus pulposus tissue), thereby relieving the patient's symptoms.

[0004] The forceps used in existing nucleus pulposus clamps are often quite sharp. When the forceps are used to grasp the diseased tissue, the sharp teeth on the forceps may scratch the nerve tissue around the diseased tissue, thereby damaging the nerve tissue and resulting in poor surgical outcomes. Utility Model Content

[0005] This invention provides a surgical tool to partially solve the aforementioned problems existing in the prior art.

[0006] The present invention adopts the following technical solution:

[0007] This utility model provides a surgical tool, which includes: a forceps head, a tube, and a protective net;

[0008] The bottom end of the rod tube is provided with a forceps head for gripping diseased tissue;

[0009] The clamps include a first clamp and a second clamp, the second clamp is fixedly connected to the rod tube, the first clamp and the second clamp are rotatably connected, and the clamps are located inside the space supported by the isolation net;

[0010] The isolation net has mesh openings that allow the diseased tissue to pass through and enter the space supported by the isolation net.

[0011] Optionally, a limiting component is provided on the rod tube near the clamp head.

[0012] Optionally, the limiting assembly consists of two protruding limiting rings fixed to the rod tube.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Currently, with the continuous development of medical technology, nucleus pulposus clamps are increasingly being used in orthopedic clinical surgery, and they have a crucial impact on surgical outcomes. For example, in lumbar disc herniation surgery, a puncture needle is first inserted to the designated location (the herniated disc), then a sleeve is inserted along the puncture needle, and after the sleeve is fixed in place, the puncture needle is withdrawn to establish a channel. The diseased tissue is then removed through this channel. Specific methods for removing the diseased tissue are as follows. Figure 1 .

[0030] Figure 1 This is a schematic diagram of an existing method for removing diseased tissue, which is provided by this utility model.

[0031] Depend on Figure 1 As can be seen, the nucleus pulposus forceps can be inserted into the channel created by the sleeve, and then the diseased tissue (i.e., the protruding nucleus pulposus) can be partially or completely removed through the forceps head, thereby relieving the patient's symptoms. However, it can also be seen that the forceps heads of existing nucleus pulposus forceps are often quite sharp. When grasping the diseased tissue, the sharp teeth on the forceps head may scratch the nerve tissue surrounding the diseased tissue, causing damage to the nerve tissue and resulting in poor surgical outcomes.

[0032] To address the problems in the prior art, this utility model provides a surgical tool, comprising: a forceps head, a tube, and an isolation net, as detailed below. Figure 2 .

[0033] Figure 2 This is a schematic diagram of a surgical tool provided by this utility model.

[0034] Depend on Figure 2As can be seen, the surgical tools may include: a forceps head 201, a rod tube 202, and an isolation net 203. The bottom end of the rod tube 202 is provided with a forceps head 201 for gripping lesion tissue. The forceps head 201 includes a first forceps head 204 and a second forceps head 205. The second forceps head 205 is fixedly connected to the rod tube 202 (for example, it can be connected to the rod tube 202 by welding), while the first forceps head 204 and the second forceps head 205 are rotatably connected (i.e., they can be rotatably connected via a pivot between them). Furthermore, the forceps head 201 is located inside the space supported by the isolation net 203, which has mesh openings that allow lesion tissue to pass through and enter the space supported by the isolation net 203.

[0035] To prevent the isolation net from detaching from the pole tube, a limiting component can be installed on the pole tube near the clamp head. This limiting component can consist of two protruding limiting rings fixed to the pole tube, as shown below. Figure 3 .

[0036] Figure 3 This is a schematic diagram of a surgical tool provided by this utility model.

[0037] Depend on Figure 3 As can be seen, there are two protruding limiting rings 306 on the pole tube 302, and correspondingly, a circular ring 307 can be provided at the top of the isolation net 303. Furthermore, the outer diameter of the circular ring 307 is smaller than the outer diameter of the limiting rings 306, thus the circular ring 307 can be confined between the two limiting rings 306 to prevent it from detaching from the pole tube 302. The distance between the two limiting rings 306 can be set to a preset value (e.g., 2 cm).

[0038] In addition, in this utility model, the isolation net can be directly fixed to the pole tube. Correspondingly, the limiting component on the pole tube can be set as a slot type, and then the ring on the isolation net can be fixed to the limiting component by a snap-fit ​​connection, so as to prevent the isolation net from detaching from the pole tube.

[0039] In addition, the surgical tools mentioned in this invention can be connected to a surgical robot to perform clinical surgeries such as lumbar disc herniation.

[0040] Specifically, the top end of the tube can be equipped with an interface component for connecting to a surgical robot. There are several ways to connect the interface component and the surgical robot. For example, the interface component can have external threads, and the corresponding connection point on the surgical robot can have internal threads, allowing the interface component to connect to the surgical robot via a threaded structure. Alternatively, the interface component can have multiple locating pins, and the corresponding connection point on the surgical robot can have multiple locating holes, allowing for a direct docking connection with the surgical robot.

[0041] In this invention, the inside of the tube may contain a steel wire with a stretching function. When the steel wire is stretched, the clamp head is in an open state; when the steel wire is contracted, the clamp head is in a closed state. For example, the steel wire inside the tube can be controlled by a connected surgical robot to control the opening or closing state of the clamp head, thereby grasping the diseased tissue.

[0042] Of course, in addition to using a surgical robot to control the surgical tools, a handle can also be provided at the tail of the surgical tools (i.e. the other end of the forceps head), so that doctors can perform clinical surgery by manipulating the handle.

[0043] In this invention, to enhance the holding force and stability of the nucleus pulposus forceps, the first and second forceps heads can be serrated. Furthermore, to ensure the surgical instruments have good corrosion resistance and biocompatibility, the isolation mesh can be made of titanium alloy; alternatively, it can also be made of stainless steel.

[0044] In summary, the overall working principle of the surgical tool provided by this utility model is as follows: first, a puncture needle is inserted to the designated location (the herniated lumbar disc), and a sleeve is inserted along the puncture needle. After the sleeve is fixed in place, the puncture needle is withdrawn to create a channel. Then, the surgical tool provided by this utility model can be inserted into the channel created by the sleeve to remove the diseased tissue (i.e., the herniated nucleus pulposus). For details, please refer to the following: Figure 4 .

[0045] Figure 4 This is a schematic diagram illustrating the removal of diseased tissue according to the present invention.

[0046] Depend on Figure 4 As can be seen, after a channel is established through the sleeve, surgical instruments can be inserted into the sleeve. The diseased tissue can pass through the mesh of the isolation net on the surgical instrument and enter the space supported by the isolation net. Then, the surgical robot can control the steel wire inside the tube to control the opening and closing of the forceps head, thereby clamping and removing the diseased tissue.

[0047] As can be seen from the above, the forceps head of the surgical tool provided by this utility model is located inside the space supported by the isolation net. During clinical surgery, due to the presence of the isolation net, the forceps head will be completely surrounded inside the isolation net, thus preventing damage to the nerve tissue around the lesion tissue, thereby greatly improving the surgical effect.

[0048] Furthermore, since the structure of the nerve tissue surrounding the lesion is often relatively regular (e.g., cylindrical), the nerve tissue usually does not enter the isolation net. That is, the nerve tissue can be isolated on the outside of the isolation net to avoid contact with the forceps inside the isolation net, reducing the risk of nerve damage during clinical surgery and greatly improving the surgical outcome.

[0049] The various embodiments in this utility model are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.

[0050] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this application.
