Background

With the wide development of endoscopic treatment, endoscopic high-frequency electrosection and electrocoagulation become more popular. Local bleeding is a common complication of endoscopic treatment. The high-frequency hemostatic forceps clamp bleeding blood vessels or focus under the direct view of an endoscope, and can achieve the purpose of hemostasis by supplying high-frequency current, so that the high-frequency hemostatic forceps are common instruments for hemostasis under the direct view of the endoscope, and have strong practical value clinically; electric polypectomy is a common operation in clinic, and usually involves biting the polyp with hot biopsy forceps and applying a high-frequency current for electric excision.

When a doctor carries out the electric excision and the electric coagulation under an endoscope, the forceps cup is a main action part, so that the forceps cup at the front end of the instrument is electrified. The head ends of products (such as thermal biopsy forceps, thermal hemostatic forceps and the like) on the market are usually designed by all metals, the electrified part is too long, and human tissues and the surface of an endoscope are easily touched by mistake during operation, so that a patient or the endoscope is scalded. And the products on the market are only used for the hemostasis operation of blood vessels, and can not perform hemostasis on wound surface bleeding of mucous membrane tissues.

Patent document with publication number CN102626335 discloses a hemostatic clamp with a four-bar structure, which comprises a chuck part, an outer tube part, a pulling cable and a handle, wherein the pulling cable is connected with the handle through a sliding ring, the outer tube part is fixedly connected with the handle, the chuck part is composed of two chucks and two connecting bars, the chuck handles of the chucks and the connecting bars form a four-bar structure, the two chucks are pinned on a chuck seat, the chuck seat is connected with the outer tube part, the two connecting bars are pinned on a pulling rod arranged at the front end of the pulling cable, the hemostatic clamp pulls the pulling cable to move back and forth through the sliding of the sliding ring on the handle, and the four-bar structure is driven by the pulling rod to move, so as to realize the closing and opening of the chucks. The outer pipe part consists of an outer pipe, a connecting sleeve, a connecting core and a connecting seat, wherein the connecting sleeve, the connecting core and the connecting seat are arranged in the outer pipe, the connecting sleeve is arranged at the front end, the assembling part of the chuck seat is arranged in the connecting sleeve, the connecting sleeve and the connecting seat are tightly connected together through the connecting core, and the connecting core is suitable for being pushed by a backward pull rod to be separated from the connecting sleeve. In the structure, the chuck component can not rotate, and the operation difficulty of the clamping hemostasis operation is high; moreover, the clipping and locking are not firm enough, and the tissue is easy to slip off.

Disclosure of Invention

In the preferred embodiment, the connecting rod 27 is a steel wire hook, and the connecting hook 2701 is integrally formed at the front end thereof; the rear ends of the two connecting rods 27 are fixed to the distal end of the mandrel 13 by a connecting tube 26.

In this embodiment, as shown in fig. 20, 22 and 23, a rotary hook hole a2002 is provided on the rotary cylinder 20, a rotary hook hole B2103 is provided on the cup holder 21, the hook 17 has a central hook hole 1701 and a hook 1702, a rotary connector 25 is fixed to the distal end of the mandrel 13, the hook 17 is disposed in the rotary cylinder 20 and is sleeved on the rotary connector 25 through the central hook hole 1701, the rotary connector 25 is matched with the central hook hole 1701 in shape so as to drive the hook 17 to rotate, and the hook 1702 of the hook 17 passes through the rotary hook hole a2002 and the rotary hook hole B2103 so as to connect the rotary cylinder 20 and the cup holder 21 for synchronous motion; when the mandrel 13 and the connecting rod 27 bring the hook 17 to move backward relative to the cup holder 21, the hook 1702 of the hook 17 is disengaged from the rotary hook hole B2103 to separate the rotary cylinder 20 from the cup holder 21.

In the preferred embodiment, the distal end of the mandrel 13 passes through the central hole 1701 of the hook 17, and the central hole 1701 of the hook 17 is fixed in a rectangular position-limiting manner with the rotation connector 25 pressed onto the mandrel 13, so that the mandrel 13 rotates to drive the hook rotation-limiting tube 25, the hook 17, the rotary cylinder 20, the cup holder 21 and the forceps cup 24 to rotate synchronously.

Other structures of this embodiment are the same as those of embodiment 1.

As shown in fig. 26, 27, 28 and 29, when the electrocoagulation hemostasis is performed, the pin 23 is located at the opening and closing position of the pin mounting hole 2102 on the cup seat 21, the forceps cup 24 can be operated to repeatedly open, close and rotate through the handle, the sliding handle 3, the rotating wheel 8 and the mandrel 13, and an external power supply can be connected through the electrode 4 on the sliding handle 3 to perform the electrocoagulation hemostasis for multiple times. After the electro-coagulation hemostasis of the wound surface is finished, if the wound needs to be sutured, the wound can be clamped and closed by using the claw ends 2401 on the forceps cup 24, after the wound is clamped and closed, the sliding handle 3 is pulled backwards continuously until the pin 23 props and deforms the pin mounting hole 2102 on the cup seat 21, as shown in fig. 30 and 31, the pin 23 is pulled to the locking position, and at the moment, the locking protrusions 2404 on the forceps cup 24 are just clamped in the releasing locking grooves 2101 of the cup seat 21 (the clicking sound can be heard in the process). The sliding handle 3 is pulled backward until the coupling hook 2701 of the coupling lever 27 is pulled and deformed to come out of the coupling hook hole 2403 of the forceps cup 24 and simultaneously the hook 17 is pulled backward, so that the hook 1702 of the hook comes out of the rotation hook hole a2002 of the rotary cylinder 20 and the rotation hook hole B2103 of the cup holder 21, as shown in fig. 32 and 33, the cup holder 21 is separated from the rotary cylinder 20, and the release is completed.
