Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a ligation clamp applicator with a blade and continuous firing function. Background Technology

[0002] In current surgical procedures, vascular ligation and dissection are crucial and essential steps. Most commercially available vascular ligation procedures utilize a single instrument. During ligation, clamps are applied and removed to secure the blood vessel or tissue. After the procedure, a cutting tool is inserted to cut the vessel or tissue. This process is repeated gradually, requiring considerable time for instrument changes. As surgical complexity increases, shortening surgical time and improving efficiency become critical challenges for instrument manufacturers. Therefore, the intelligent and integrated development of surgical instruments is a current research and development direction for surgical instruments.

[0003] In other words, in actual operation, after ligation of blood vessels or tissues, it is often necessary to cut the ligated blood vessels or tissues. Under the current technological background, especially in endoscopic minimally invasive surgery, the required incision size is getting smaller and smaller, and the requirements for the size and precision of instruments are also becoming more and more stringent. Due to space constraints, the ligation instruments and cutting instruments on the market are currently independent devices, so they must be operated separately and gradually unfolded, making it difficult to optimize in terms of time saving.

[0025] like Figure 1-6 As shown: A ligation clamp applicator with a blade, the main body of which is a ligation clamp applicator, the ligation clamp applicator is divided into an applicating part 1 and a firing part 2. The firing part 2 controls the back-and-forth movement of the push rod 11 in the applicating part 1 to realize the actions of clamping, slightly closing the clamp head 13, and closing the clamp head 13; characterized in that:

[0026] It also includes a cutting assembly, which includes a blade 31, a solenoid valve 32, a main control board 33, a power supply 34, and a cutting button 35;

[0027] The main control board 33 and the power supply 34 are both installed inside the firing part 2 and are electrically connected to each other; the cutting button 35 is installed on the outer wall of the firing part 2 and is electrically connected to the main control board 33.

[0028] The solenoid valve 32 is installed on the inner wall of the front end of the sleeve 12 of the clamping part 1 and is electrically connected to the main control board 33; the cutting tool 31 is connected to the solenoid valve 32 and is arranged on the side of the clamp head 13 of the clamping part 1.

[0029] The clamp head 13 is closed vertically, and the cutter 31 is positioned on the left or right side of the clamp head 13. This ensures that after the ligation clip completes the ligation, the tissue on the side of the ligation clip is cut.

[0030] like Figure 5 As shown: An electric drive structure is installed inside the firing section 2;

[0031] The electric drive structure includes a motor 41, a rack 42, and a control button 43; the motor 41 is connected to a power supply 34, and a gear 44 is provided on the output shaft of the motor 41. The rack 42 is limited and installed in the firing part 2 and can slide back and forth in the firing part 2. The gear 44 meshes with the rack 42; the control button 43 is connected to the motor 41 through the main control board 33.

[0032] Furthermore, the control button 43 is divided into a micro-closing switch 431 and a closing switch 432. The micro-closing switch 431 controls the travel distance of the push rod 11 to achieve micro-closing of the pliers 13, and the closing switch 432 controls the travel distance of the push rod 11 to achieve closing of the pliers 13.

[0033] The electric drive structure also includes a limit switch 45, and a protrusion 451 corresponding to the limit switch 45 is provided on the rack 42. The position of the protrusion 451 is such that when the rack 42 drives the clamp head 13 to close, the protrusion 451 contacts the limit switch 45. Here, the limit switch 45 also sends a signal to the main control board 33, so that when the rack resets, it will automatically allow the rack to travel a certain distance to achieve one clamping operation.

[0034] It also includes a mode switch 36, which is mounted on the outer wall of the firing section 2 and electrically connected to the main control board 33; it is used to control the on or off of the cutting button 35. This enables two modes: single clamping and ligation mode, and clamping and ligation + cutting mode.

[0035] The clamping part 1 and the firing part 2 are detachably connected;

[0036] The firing part 2 has a limiting tube 22 at its front end, and the limiting tube 22 has a limiting ring groove at its front end. The front end of the rack 42 passes into the limiting tube 22.

[0037] The sleeve 12 of the clamping part 1 is provided with a rotating handle 14 on its outer periphery, and the rotating handle 14 is provided with a locking switch 15 that cooperates with the limiting ring groove.

[0038] The push rod 11 has a first conductive plate at its rear end and a second conductive plate at its front end. The first conductive plate is electrically connected to the solenoid valve 32 and the second conductive plate is electrically connected to the main control board 33.

[0039] Its working principle is as follows:

[0040] The steps for the clip ligation method are as follows:

[0041] Step 1: Power On: Connect to a power source or install a power source. The power source here is usually a replaceable battery. An independent power source that is connected by a clip can replace the battery, ensuring the smooth completion of the surgery. The installation is also very convenient.

[0042] Step 2, Install the clip application unit 1: Select the appropriate clip application unit 1 according to the specific blood vessel size, such as size S, size M, size L, etc., and directly insert the rotating mechanism 2 of the clip application unit 1 into the limiting tube 22. This is very convenient and fast, and meets the switching needs of different blood vessels or tissues. The firing unit 2 can also be equipped with an identification device to identify the clip application unit 1.

[0043] Step 3, clamping the ligation clip: This patent uses a motor-driven gear 44 to move, which in turn drives the rack 42 forward, pushing the ligation clip in the clamping part 1 forward, and further pushing the ligation clip to the clamp head to achieve clamping; the entire process is driven by the motor 41, which is very convenient. It should be noted that the clamping process here can be achieved by pressing the micro-closing switch.

[0044] Step 4: Inserting the ligation clip into the body: This step is mainly used in endoscopic minimally invasive surgery. By pressing the micro-closing button 431, the motor is started to rotate, causing the rack 42 to continue moving forward, thereby pushing the push rod 11 forward and thus micro-closing the ligation clip. The purpose of micro-closing the ligation clip and clamp head is to allow the cannula of the clamping part to pass smoothly through the trocar; after the cannula enters the body, the micro-closing button 432 needs to be activated to make the motor rotate in the opposite direction, causing the rack to move backward, thereby moving the push rod 5 backward, thus reopening the ligation clip.

[0045] Step 5, Clamping process: When the opened ligation clip has wrapped around the blood vessel or tissue and is ready to clamp the blood vessel, press the closing switch 432 to start the motor to rotate, so that the rack continues to move forward to a specific position, thereby pushing the push rod forward to a specific position, so that the ligation clip is completely closed.

[0046] Step 6, Continuous clamping: After the ligation clamp is closed, the limit switch 45 will send a signal back to the main control board, repeating the clamping process of step 3; when it is necessary to clamp again at an appropriate position, follow step 6.

[0047] Step 7, retracting the clamping device front lever: When the clamping is completed and the instrument needs to be retracted from the body, press the micro-closing switch to make the ligation clamp slightly close and then withdraw it from the body.

[0048] The main body of this product is reusable. When using it, only the clamping part 1 needs to be replaced. The firing part 2 can be reused by disinfection or by adding a protective shell when using it.

[0049] Clamping and ligation + cutting mode

[0050] The specific steps are as follows:

[0051] The steps from startup to entry into the human body to prepare for ligation are the same as steps 1-4 in the clamping ligation mode. When it is confirmed that this segment of blood vessel or tissue needs to be cut, the mode switch 36 needs to be switched to the clamping ligation + cutting mode. At this time, the electronic control system will automatically switch the action mode.

[0052] Step 5, Clamping process: When the opened ligation clip has wrapped around the blood vessel or tissue and is ready to clamp the blood vessel, press the closing switch 432 to start the motor to rotate, so that the rack continues to move forward to a specific position, thereby pushing the push rod forward to a specific position, so that the ligation clip is completely closed.

[0053] Step 6: Cutting Process: After the ligation clip is fully closed, the instrument will remain closed. Activate the cutting button to actuate the solenoid valve 32, which will push out the blade 31 to cut the blood vessel or tissue.

[0054] Step 7, Continuous clamping: After the ligation clamp is closed, the limit switch 45 will send a signal back to the main control board, repeating the clamping process of step 3; when it is necessary to clamp again at an appropriate position, follow step 7.

[0055] Step 8: Retract the front lever of the clamping device: When the clamping is completed and the instrument needs to be retracted from the body, press the micro-closing switch to make the ligation clamp slightly close and then withdraw it from the body.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
