Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an electrocoagulation forceps with a detachable and replaceable forceps head. Background Technology

[0002] Electrocoagulation has a long history of use in surgical hemostasis, employing high-frequency currents (frequency ranging from thousands to over 2 megacycles per second). High-frequency currents, even at voltages of several thousand volts, can safely pass through the human body without causing nerve or muscle reactions. The thermal effect of the high-frequency current dehydrates and shrinks the blood vessel walls, causing the blood to coagulate and fuse the vessel and blood clot together, achieving effective hemostasis. During surgery, electrocoagulation forceps clamp the conductive electrodes to achieve hemostasis.

[0003] However, when using existing electrocoagulation forceps, after electrocoagulation, it is often necessary to use scissors or other instruments to cut the coagulated blood vessel for the next surgical procedure. In short, existing electrocoagulation forceps only perform the function of clamping and electrocoagulation, and do not have the function of cutting human tissue. Their function is relatively simple and cannot meet the needs of surgery. Furthermore, the main function of existing electrocoagulation forceps is to electrocoagulate and close and cut blood vessels. The forceps head is particularly prone to damage, causing electrocoagulation failure. Moreover, the forceps head and the forceps bar of existing electrocoagulation forceps are integrated, which causes a lot of waste in clinical surgery. It is necessary to have a forceps head that can be quickly replaced. Utility Model Content

[0004] The purpose of this invention is to provide an electrocoagulation forceps with a detachable and replaceable forceps head. This invention can simultaneously close and cut blood vessels, and has the advantage of a detachable and replaceable forceps head.

[0005] The technical solution of this utility model is: an electrocautery pliers with detachable and replaceable pliers heads, including a pliers head assembly, a pliers bar connected to the pliers head assembly and driving the pliers head to open and close by axial movement, a pliers bar sleeve connected to the pliers bar and driving the pliers bar to move axially, and a handle.

[0006] In the aforementioned electrocautery pliers with detachable and replaceable pliers heads, the pliers head assembly includes an upper pliers head and a lower pliers head. An insulating connector is installed between the upper pliers head and the lower pliers head. The lower pliers head passes through the insulating connector and is connected to a pliers head rod. The end of the pliers head rod is threadedly connected to a pliers bar. A pliers bar sleeve is fitted on the outside of the pliers bar. One end of the pliers bar sleeve is connected to the upper pliers head, and the other end is connected to a rotating wheel and a handle. The rotating wheel is used to control the rotation of the pliers bar. The handle includes a fixed handle and a movable handle that is rotatably connected around the fixed handle.

[0007] In the aforementioned electrocautery pliers with detachable and replaceable pliers heads, one end of the lower pliers head is provided with a narrow and long biting surface, and the other end is provided with a mounting ear. The mounting ear is rotatably connected to one end of the pliers head rod by a short pin.

[0008] In the aforementioned electrocautery pliers with detachable and replaceable pliers heads, one end of the upper pliers head is provided with a biting surface, and the inner side of the biting surface is provided with serrated gripping teeth; the other end is provided with a mounting groove, and the insulating connector is embedded in the mounting groove.

[0009] In the aforementioned electrocautery pliers with detachable and replaceable pliers heads, the upper pliers head and the pliers bar are threadedly fixedly connected; the pliers head bar is threadedly fixedly connected to the pliers bar.

[0010] In the aforementioned electrocautery pliers with detachable and replaceable pliers heads, the upper pliers head, the lower pliers head, and the insulating connector are all provided with pin holes, and the upper pliers head, the lower pliers head, and the insulating connector are rotatably connected through the pin holes using long pins.

[0011] Compared with the prior art, this utility model designs the lower clamp head biting surface as narrow and long, and the upper clamp head biting surface is provided with gripping teeth, so that during the electrocoagulation process, it can both grasp and clamp the blood vessel tissue, and cut the blood vessel tissue by the lower clamp head biting surface after electrocoagulation.

[0012] Meanwhile, the jaws are connected to the jaw bar via a threaded connection in the jaw assembly, and the upper jaw is connected to the jaw bar sleeve via a threaded connection. The jaw bar drives the lower jaw to swing, and the jaw bar sleeve pulls the upper jaw. Through the cooperation of the upper and lower jaws, the opening and closing action of the jaws is completed, ensuring the reliability of the instrument. Furthermore, the jaw assembly can be completely disassembled via the threaded connection. When the jaw assembly is unusable, it can be quickly replaced, saving resources. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example 1.

[0019] A type of electrocautery pliers with detachable and replaceable pliers heads, such as Figure 1-3As shown, the pliers include a pliers head assembly 1, which includes an upper pliers head 11 and a lower pliers head 12. An insulating connector 13 is installed between the upper pliers head 11 and the lower pliers head 12. The lower pliers head 12 passes through the insulating connector 13 and is connected to a pliers head rod 14. The end of the pliers head rod 14 is threadedly connected to a pliers rod 2. A pliers rod sleeve 3 is fitted on the outside of the pliers rod 2. One end of the pliers rod sleeve 3 is threadedly connected to the upper pliers head 11, and the other end is connected to a rotating wheel 4 and a handle. The rotating wheel 4 is used to control the rotation of the pliers rod 2, and the pliers rod 2 drives the pliers head assembly 1 to rotate.

[0020] The lower jaw 12 has a narrow and long biting surface at one end and a mounting ear 121 at the other end. The mounting ear 121 is rotatably connected to one end of the jaw bar 14 via a short pin 16.

[0021] One end of the upper clamp head 11 is provided with a biting surface, and the inner side of the biting surface is provided with serrated gripping teeth; the other end is provided with a mounting groove 111, and the insulating connector 13 is embedded in the mounting groove 111.

[0022] The clamp head bar 14 and the clamp bar 2 are fixedly connected by threads.

[0023] The upper clamp head 11, the lower clamp head 12, and the insulating connector 13 are all provided with pin holes, and the three are rotatably connected by a long pin 15 through the pin holes.

[0024] The handle includes a fixed handle 51 and a movable handle 52 rotatably connected around the fixed handle 51. By pushing or pulling the movable handle 52, the pliers assembly 1 can complete the opening and closing action.

[0025] By pushing the movable handle 52 forward, the clamp bar 2 and the clamp head bar 14 move forward together. The clamp head bar 14 causes the lower clamp head 12 to swing downward. At the same time, the fixed handle 51 remains stationary, ensuring that the clamp bar sleeve 3 pulls the upper clamp head 11, thus completing the opening action of the clamp head assembly 1.

[0026] By pulling the movable handle 52 backward, the clamp bar 2 and the clamp head bar 14 move backward. The clamp head bar 14 causes the lower clamp head 12 to swing upward, while the fixed handle 51 remains stationary, ensuring that the clamp bar sleeve 3 presses against the upper clamp head 11, thus completing the closing action of the clamp head assembly 1.

[0027] When cleaning, disinfection, or replacement of the pliers head assembly 1 is required, first press button A, gently pull the pliers head assembly 1, so that the pull rod 2 disengages from the installation position of the fixed handle 51, the upper pliers head 11 in the pliers head assembly is unscrewed and separated from the pliers bar sleeve 3, pull out the pull rod 2 along with the pliers head assembly 1, and unscrew the pliers head bar 14 from the pull rod 2.
