BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The drawings described herein are used to provide a further understanding of this specification and constitute a part of this specification. The illustrative embodiments and descriptions of this specification are used to explain this specification and do not constitute an improper limitation on this specification. In the drawings:

[0033] Figure 1 This is a schematic diagram of a structural cross-section of a multifunctional surgical tool in this manual. DETAILED DESCRIPTION

[0034] In a minimally invasive surgery environment, doctors or surgical robots need to use endoscopes to operate surgical tools to perform various surgical operations in the patient's body. Usually, the working cannula of the endoscope is narrow in diameter, and the space in the patient's body is generally narrow, so it is necessary to be very careful when changing surgical tools.

[0035] During various lumbar disc surgeries, the soft tissues at the surgical site need to be clamped and electrocoagulated frequently, so the surgical tools have to be frequently switched between the nucleus pulposus forceps and the electrocoagulation forceps. The process of changing surgical tools needs to be performed carefully and is usually very slow. Therefore, frequent changes of surgical tools will greatly increase the time of the operation, which in turn increases the possibility of errors during the operation and increases the risk of the operation.

[0036] In order to solve the above technical problems, this specification provides a multifunctional surgical tool to avoid frequent replacement of surgical tools during minimally invasive surgery.

[0037] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0039] Figure 1 is a schematic diagram of a cross-sectional structure of a multifunctional surgical tool in this specification, such as Figure 1As shown, the multifunctional surgical tool comprises: a forceps head 1, a cavity 2, a rotating shaft 3, a transmission rod 4, an operating rod 5, and a wire 6; the forceps head 1 is hinged at the head of the cavity 2 through the rotating shaft 3, one end of the rotating shaft 3 is fixed in the forceps head 1, and the other end is embedded in the cavity 2, the head of the transmission rod 4 is connected to the tail of the forceps head 1, and the tail of the transmission rod 4 is connected to the head of the operating rod 5, the wire 6 comprises a first wire 601 and a second wire 602, the head of the first wire 601 is connected to the forceps head 1, the head of the second wire 602 is connected to the transmission rod 4, and the tails of the first wire 601 and the second wire 602 are connected to an external power source;

[0040] The forceps head 1 is used to clamp the target tissue during surgery; the cavity 2 is used to accommodate other components in the multifunctional surgical tool; the rotating shaft 3 is used to connect the forceps head 1 and the cavity 2, and make the forceps head 1 rotate around the rotating shaft 3; the transmission rod 4 is used to drive the forceps head 1 to rotate around the rotating shaft 3 under the drive of the operating rod 5; the operating rod 5 is used to drive the transmission rod 4 to move in a straight line under the action of external force; the wire 6 is used to provide power to the forceps head 1 through the external power supply, so that the forceps head 1 electrocoagulates the target tissue.

[0041] like Figure 1 As shown, the "head" of each component involved in this specification is Figure 1 The leftmost part of the component; the "tail" of each component is Figure 1 In order to ensure the simplicity and understanding of the specification, in the subsequent description of this specification, unless otherwise specified, the "head" and "tail" of the component are distinguished according to the above description.

[0042] The multifunctional surgical tool provided by this function can be applied to a variety of different surgical scenarios. In order to make the explanation of this specification clearer, this specification uses the application scenario of lumbar disc surgery as an example to illustrate the multifunctional surgical tool provided by this specification.

[0043] like Figure 1 As shown, the forceps head 1 is located at the head of the multifunctional surgical tool, and its tail is connected to the head of the cavity 2, which can be used to clamp the soft tissue in the target area during surgery. Figure 1 In addition to the shape shown in the figure, the forceps head 1 can also be in many other different shapes, corresponding to various minimally invasive surgical forceps heads, such as the heads of various minimally invasive surgical forceps (straight nucleus pulposus forceps, 45° nucleus pulposus forceps, biting forceps, graspable curved forceps, etc.) used in lumbar disc surgery. It can be imagined that the forceps head 1 can be replaced at any time to cope with different application scenarios.

[0044] The cavity 2 is a hollow container that is closed on all sides and open at the head and tail. The head is hinged to the forceps head 1 through a rotating shaft 3, and the tail is open to provide a movable space for the transmission rod 4. The interior of the cavity 2 is used to carry other components in the multifunctional surgical tool, including but not limited to the transmission rod 4, the guide wire 6 and other components. Among them, the cavity 2 can have a variety of different shapes. In order to cooperate with the working channel of the endoscope used in minimally invasive surgery, the shape of the cavity 2 is usually an elongated cylinder or a rectangular parallelepiped, etc., and this specification does not make specific restrictions on this.

[0045] There is a rotating shaft 3 connecting the pliers head 1 and the cavity 2, and the tail of the pliers head 1 and the head of the cavity 2 are hinged through the rotating shaft 3. The function of the rotating shaft 3 is to enable the pliers head 1 to rotate around the rotating shaft 3, so as to realize the opening and closing of the pliers head 1. There are many ways for the rotating shaft 3 to connect the pliers head 1 and the cavity 2. For example, the tail of the pliers head 1 and the head of the cavity 2 may have grooves matching the rotating shaft 3, so that the rotating shaft 3 can be placed therein; for another example, the rotating shaft 3 may exist in the form of a protrusion at the tail of the pliers head 1, and the head of the cavity 2 may have a corresponding groove, and the protrusion and the groove match each other. Of course, the positions of the protrusion and the groove may also be interchanged, and this specification does not impose specific restrictions on this.

[0046] The transmission rod 4 is arranged inside the cavity 2, and its head is connected to the tail of the forceps head 1, and the tail is connected to the head of the operating rod 5. During the movement of the cavity 2, the forceps head 1 can be pushed to rotate around the rotating shaft 3. The operating rod 5 is close to the tail of the cavity 2, arranged outside the cavity 2, and its head is connected to the tail of the transmission rod 4. In the actual use of the multifunctional surgical tool provided in this specification, the user can apply external force to the operating rod 5 to move the operating rod 5 and drive the transmission rod 4 to move, thereby causing the transmission rod 4 to drive the forceps head 1 to open and close.

[0047] Part of the wire 6 is arranged in the cavity 2, and part of it is arranged outside the cavity 2. The wire 6 is a conductive connecting wire. Generally, when providing power to an energized device, it is necessary to connect the live wire and the neutral wire to the energized device at the same time. Based on this, the wire 6 includes a first wire 601 and a second wire 602. Among them, the first wire 601 can be the live wire and the second wire 602 can be the neutral wire; or the second wire 602 can be the live wire and the first wire 601 can be the neutral wire. This specification does not make specific restrictions on this. Among them, the head of the first wire 601 is connected to the clamp head 1, and the head of the second wire 602 is connected to the transmission rod 4; the tails of the first wire 601 and the second wire 602 are extended to the outside and connected to the external power supply. A small opening is provided on the lower wall of the cavity 2 for the first wire 601 and the second wire 602 to pass through. Since the transmission rod 4 is connected to the clamp head 1, the second wire 602 can still conduct electricity to the clamp head 1 through the transmission rod 4.

[0048] When the forceps head 1 is powered on, the electrocoagulation function can be realized, and the soft tissue that is difficult to be removed from the patient's body can be electrolyzed and ablated by power. At the same time, the electrocoagulation can also be used to stop bleeding for the patient.

[0049] The multifunctional surgical tool provided in this specification can easily control the opening and closing of the clamp head 1 through the linkage structure between the clamp head 1, the rotating shaft 3, the transmission rod 4, and the operating rod 5 through the operating rod 5; at the same time, the clamp head 1 can be energized through the wire 6 to enable the clamp head 1 to achieve the electrocoagulation function. When the multifunctional surgical tool provided in this specification is used, two different surgical operations of clamping and electrocoagulation can be achieved simultaneously without switching surgical tools, eliminating the tedious steps of frequently changing surgical tools during the operation, saving a lot of time for the operation, and effectively reducing the probability of surgical errors.

[0050] Preferably, in the actual application process, since the pliers head 1 needs to be opened and closed continuously, the structure of the pliers head 1 can be optimized to make the pliers head 1 more convenient to open and close. Specifically, the pliers head 1 may include: an upper pliers head 101 and a lower pliers head 102; the upper pliers head 101 is hinged to the upper wall of the head of the cavity 2 through the rotating shaft 3; the lower pliers head 102 is connected to the lower wall of the head of the cavity 2; the upper pliers head 101 is used to rotate around the rotating shaft 3 to realize the opening and closing of the pliers head 1.

[0051] In the multifunctional surgery provided in this manual, Figure 1 As shown, the structure of the pliers head 1 is separated into an upper pliers head 101 and a lower pliers head 102 which are not connected to each other, wherein the tail of the upper pliers head 101 is hinged to the upper wall of the head of the cavity 2 via the rotating shaft 3, and the lower pliers head 102 is connected to the lower wall of the head of the cavity 2. Under the above structure, the upper pliers head 101 can rotate around the rotating shaft 3, while the lower pliers head 102 is fixed and the two are separated from each other. Thus, the pliers head 1 can be opened and closed more flexibly.

[0052] Preferably, the head of the transmission rod 4 is connected to the tail of the upper clamp head 101, and the head of the first wire 601 is connected to the tail of the lower clamp head 102. When the structure of the clamp head 1 is separated into the upper clamp head 101 and the lower clamp head 102, since the upper clamp head 101 can rotate, the transmission rod 4 should be connected to the upper clamp head 101 to drive the upper clamp head 101 to rotate. When the transmission rod 4 is connected to the second wire 602, the first wire 601 needs to be connected to the lower clamp head 102 so that the upper clamp head 101 and the lower clamp head 102 can be powered when they are closed. Figure 1 As shown, the first wire 601 can pass through the cavity 2 and be connected to the lower clamp head 102 .

[0053] Preferably, the cavity 2 is a cylindrical hollow cavity, and the cavity 2 is made of insulating material. Usually, the working channel of the endoscope used in minimally invasive surgery is a cylinder, so the cavity 2 can be set as a cylindrical hollow cavity to match the working channel of the endoscope to the greatest extent, so that the space inside the cavity 2 is larger and can better accommodate other components of the multifunctional surgical tool. At the same time, since the multifunctional surgical tool provided in this specification needs to be powered, in order to prevent current leakage, the cavity 2 can be made of insulating material to ensure safety when using the multifunctional surgical tool.

[0054] Preferably, the transmission rod 4 and the wire 6 are made of conductive metal material, and the outermost layers of the transmission rod 4 and the wire 6 are provided with an insulating layer. It can be imagined that the space in the cavity 2 is actually small, and the components carried in the cavity 2 are likely to come into contact with each other. When the conductive transmission rod 4 and the wire 6 directly contact other components or each other during the power-on process, it is likely to cause problems such as short circuit of the components. Therefore, an insulating layer made of insulating material can be added to the outermost layers of the transmission rod 4 and the wire 6 to prevent direct contact with other components.

[0055] More preferably, the multifunctional surgical tool further comprises a piston 7. Figure 1 As shown, the piston 7 is connected to the tail of the transmission rod 4 on one side and to the head of the operating rod 5 on the other side; the piston 7 is used to connect the transmission rod 4 and the operating rod 5. In practical applications, since the transmission rod 4 and the operating rod 5 are both in the shape of thin and long strips, it is difficult to connect the two more firmly. Therefore, a piston 7 can be added between the two, and the piston 7 can fix the transmission rod 4 and the operating rod 5 more stably, making the connection between the two more firm.

[0056] Preferably, the multifunctional surgical tool further comprises a spring 8. Figure 1 As shown, one end of the spring 8 is connected to the tail of the cavity 2, and the other end is connected to one side of the piston 7; the spring 8 is used to provide elastic force to move the piston 7 away from the cavity 2 when released from the compressed state. When the multifunctional surgical tool is actually used, its angle is usually placed vertically, that is, it is used with the head down and the tail up. In this case, when there is no external force, the transmission rod 4 and the operating rod 5 may cause the forceps head 1 to be in an open state due to the natural fall of gravity. This operation method requires continuous adjustment of the operating rod 5 when clamping soft tissue, which is very laborious, so a spring 8 can be added between the piston 7 and the cavity 2. In the natural state, the spring 8 naturally stretches and ensures that the forceps head 1 is in a closed state, thereby making the operation of the multifunctional surgical tool simpler and more efficient.

[0057] More preferably, the spring 8 includes: a first spring 801 and a second spring 802; the first spring 801 and the second spring 802 are respectively arranged on both sides of the tail of the transmission rod 4, the head of the first spring 801 is connected to the upper wall of the tail of the cavity 2, the head of the second spring 802 is connected to the lower wall of the tail of the cavity 2, and the tails of the first spring 801 and the second spring 802 are connected to one side of the piston 7. The spring 8 may further include a first spring 801 and a second spring 802, which are respectively arranged on both sides of the tail of the transmission rod 4. The above arrangement can further improve the manipulability of the multifunctional surgical tool.

[0058] Preferably, the multifunctional surgical tool further comprises: a sleeve 9; the head of the sleeve 9 is sleeved on the tail of the cavity 2, the tail of the sleeve 9 is provided with an opening, and the operating rod 5 passes through the opening; the sleeve 9 is used to limit the range of motion of the operating rod 5. It can be imagined that in the process of actual application, it is necessary to control the opening and closing angle of the pliers head 1 to a certain extent, so the opening and closing angle of the pliers head 1 can be controlled by limiting the range of motion of the operating rod 5. An opening is provided at the center of the tail of the sleeve 9, and the size of the opening is wider than the width of the operating rod 5 and smaller than the width of the piston 7, so that only the operating rod 5 can pass through. The width of the sleeve 9 can be similar to the width of the piston 7 and slightly wider than the piston 7, so that the operating rod 5 maintains a linear motion along the horizontal midline direction of the cavity 2. At the same time, the height of the sleeve 9 from the head to the tail can be set according to demand, and the set height is the range of length in which the operating rod 5 can move, and this specification does not make specific restrictions on this.

[0059] Preferably, the multifunctional surgical tool further comprises: a plug 10; the plug 10 is connected to the tail of the first wire 601 and to the tail of the second wire 602; the plug 10 is used to connect to an external power source so that the first wire 601 and the second wire 602 provide power for the multifunctional surgical tool. In actual application, when the first wire 601 and the second wire 602 are connected to an external power source, the connection relationship between the multifunctional surgical tool and the external power source is fixed and difficult to replace, which will cause a certain degree of inconvenience to the use of the multifunctional surgical tool. Therefore, the tails of the first wire 601 and the second wire 602 can be encapsulated in the plug 10, and the external power source can be connected through the plug 10 when in use. When the use is finished, the connection between the multifunctional surgical tool and the external power source can be released by simply unplugging the plug 10 from the external power source, making the use of the multifunctional surgical tool more convenient.

[0060] The above description is only an embodiment of this specification and is not intended to limit this specification. For those skilled in the art, this specification may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this specification should be included in the scope of the claims of this application.
