Description

Technical Field

[0001] This application relates to the field of laparoscopic surgical instruments, and more particularly to a laparoscopic surgical tool and laparoscopic scissors. Background Technology

[0002] During laparoscopic surgery, tissues need to be heated to coagulate or cut. This heating process generates a lot of smoke. Without additional smoke extraction equipment, the smoke will adhere to the camera used in laparoscopic surgery, causing the image to become blurry and affecting the operation. Furthermore, the protective sleeves of existing laparoscopic surgical tools do not cover the metal parts at the head and tail of the tool. During laparoscopic surgery, these parts often come into contact with internal tissues, leading to secondary injuries. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a laparoscopic surgical tool and laparoscopic scissors.

[0004] The technical solution of this application is implemented as follows:

[0005] In a first aspect, this application provides a laparoscopic surgical tool, the tool comprising:

[0006] Pliers handle;

[0007] A clamp bar body, one end of which is mounted on the clamp handle;

[0008] The working head is installed at the end of the clamp bar body away from the clamp handle;

[0009] The clamp bar has a hollow structure so that a smoke channel is formed in its middle. Several smoke holes are opened on the outer periphery of the part of the clamp bar near the working head. Several smoke holes are evenly distributed along the circumference of the clamp bar and are connected to the smoke channel.

[0010] The clamp rod body is also provided with a smoke exhaust channel, which is connected to the smoke extraction channel and connected to the smoke exhaust machine;

[0011] The smoke exhaust duct has opening and closing components for opening and closing the smoke exhaust duct.

[0012] Secondly, this application also provides a laparoscopic scissor, including the laparoscopic surgical tool described above, wherein the working head is a scissor assembly.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following:

[0014] The smoke exhaust channel creates negative pressure within the suction duct of the forceps body, allowing smoke near the forceps body to enter the suction duct through the smoke inlet. This absorbs and removes smoke from the vicinity of the forceps body, preventing smoke from spreading near the surgical area and adhering to the camera used in laparoscopic surgery, thus avoiding blurring the image. At the same time, the extension effectively covers the exposed metal parts at the rear of the working head, exposing the parts used for cutting or scalding, ensuring the working head can function normally and preventing the metal parts from contacting internal tissues during laparoscopic surgery, thus avoiding secondary injury.

[0028] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0029] Reference Figure 1 and Figure 2 A laparoscopic surgical tool, comprising: a handle 10 on which an electrode connector 13 is mounted; a lever body 20 on which one end is mounted on the handle 10; and a working head 21 mounted on the end of the lever body 20 away from the handle 10.

[0030] The clamp bar body 20 has a hollow structure to form a smoke passage 22 in its middle. Several smoke holes 23 are opened on the outer periphery of the part of the clamp bar body 20 near the working head 21. Several smoke holes 23 are evenly distributed along the circumference of the clamp bar body 20, and several groups of smoke holes 23 are evenly distributed along the axial direction of the clamp bar body 20. The smoke holes 23 are connected to the smoke passage 22. Then, a smoke exhaust passage 11 is also provided on the clamp bar body 20. The smoke exhaust passage 11 is connected to the smoke passage 22. An external smoke exhaust fan is connected to the smoke exhaust passage 11. A negative pressure is formed in the smoke passage 22 through the smoke exhaust passage 11, so that the smoke generated near the working head 21 enters the smoke passage 22 through the smoke holes 23 for smoke exhaust.

[0031] As a further improvement to the above structure, the tool further includes: a smoke baffle 12, which is installed inside the clamp handle 10, such as... Figure 7 As shown, this can prevent smoke from entering other parts of the handle 10, ensuring smoke extraction efficiency.

[0032] In addition, the smoke exhaust duct 11 has an opening and closing component 111 for opening and closing the smoke exhaust duct 11. The opening and closing component 111 includes an opening and closing valve 1111, which is slidably installed in the handle 10. The opening and closing of the smoke exhaust duct 11 is achieved by the misalignment and overlap between the opening and closing valve 1111 and the smoke exhaust duct 11.

[0033] The opening and closing component 111 also includes a handle 1113, which is installed on the side wall of the opening and closing valve 1111, and the end of the handle 1113 extends out of the outside of the clamp 10. The handle 1113 is slidably connected to the smoke exhaust channel 11 through the slide groove 112. The user can move the opening and closing valve 1111 by the handle 1113 so that it overlaps or is misaligned with the smoke exhaust channel 11.

[0034] The opening and closing component 111 also includes a spring 1112, which is installed between the opening and closing valve 1111 and the smoke baffle plate 12. One end of the spring 1112 abuts against the opening and closing valve 1111, and the other end abuts against the smoke baffle plate 12. The spring 1112 is a compression spring 1112. When the user moves the opening and closing valve 1111 to make it misalign with the smoke exhaust channel 11, the spring 1112 will be compressed. When the user releases the hand, the spring 1112 will push the opening and closing valve 1111 to make it coincide with the smoke exhaust channel 11, so that the smoke exhaust channel 11 is in the closed state under normal conditions.

[0035] Based on the further improvement of the above structure, an extension plate 1114 is installed at the end of the opening and closing valve 1111 away from the spring 1112. The extension plate 1114 is used to block the slide groove 112 so that the slide groove 112 is always closed no matter where the opening and closing valve 1111 is, to prevent smoke from flowing out of the slide groove 112 or outside air from entering the smoke exhaust channel 11 through the slide groove 112.

[0036] As a further improvement to the above structure, the tool further includes a protective sleeve 30, which is fitted around the outer periphery of the clamp bar 20; a protective mesh area 31 is formed at the position corresponding to the smoke hole 23 on the protective sleeve 30, and the hollow protective mesh area 31 can effectively prevent tissue fluid or blood and other debris from entering the smoke channel 22 during the working process.

[0037] Based on further improvements to the existing technology, the protective sleeve 30 has an extension 32 near the working head 21. The extension 32 wraps around the part of the working head 21 near the clamp body 20, and the end of the working head 21 extends out of the extension 32, so that there is a distance L between the end of the working head 21 and the extension 32, wherein the length of the distance L is 5mm. The extension 32 can effectively wrap around the exposed metal parts at the rear end of the working head 21 and expose the part used for cutting or scalding, ensuring that the working head 21 can work normally and avoiding the metal parts from touching the tissues inside the human body during laparoscopic surgery, thus preventing secondary damage.

[0038] An embodiment of this utility model also provides a laparoscopic scissor, including the laparoscopic surgical tool as described above. The working head 21 is a scissor assembly. The extension 32 wraps around the pivot of the scissor assembly and exposes the blade of the scissor, ensuring that the scissor can work normally and preventing the metal parts from contacting the tissues inside the human body during laparoscopic surgery, thus avoiding secondary injury.
