Embodiment 1
[0063] like figure 1 A hemostatic clamp with rotation shown includes a handle, a slide handle 3, a mandrel 13, a spring tube 14, a cup holder 21, a connector, a pin 23 and two pliers cups 24, and the mandrel 13 passes through the spring In the tube 14, the proximal end of the spring tube 14 is connected to the handle, the far end of the spring tube 14 is connected to the cup holder 21, the proximal end of the mandrel 13 is connected to the sliding handle 3, and the far end of the mandrel 13 is connected to the two pliers cups 24 through the connector. Connected, two pliers cups 24 are hinged and arranged on the front portion of the cup holder 21.
[0064] like figure 1 As shown, in this embodiment, the sliding handle 3 is provided with an electrode 4 for connecting to an external power source, and the electrode 4 is electrically connected to the proximal end of the mandrel 13 . Preferably in this embodiment, the electrode 4 is connected to the mandrel 13 through the electrod...
Embodiment 2
[0079] Such as Figure 20 A hemostatic clamp with rotation shown differs from Embodiment 1 only in that:
[0080] In this example, if Figure 20 , Figure 21 , Figure 24 and Figure 25 As shown, the connector includes two connecting rods 27, the front ends of the connecting rods 27 are connected to the connecting hook holes 2403 at the rear end of the pliers cup 24 through the connecting hook 2701, and the rear ends of the connecting rods 27 are fixedly connected to the distal end of the mandrel 13.
[0081] Preferably in this embodiment, the connecting rod 27 is a wire hook, and the connecting hook 2701 is integrally formed at its front end;
[0082] In this example, if Figure 20 , Figure 22 and Figure 23 As shown, the rotating cylinder 20 is provided with a rotating hook hole A2002, the cup holder 21 is provided with a rotating hook hole B2103, the hook 17 has a hook center hole 1701 and a hook 1702, and the distal end of the mandrel 13 is fixed with a rotating co...

Abstract
The invention discloses a hemostatic forceps clip and a clip head component thereof, the clip head component comprises a cup base, a pin and two forceps cups, the two forceps cups are hinged through the pin, two oppositely arranged mounting arms of the cup base are provided with a release locking groove and a pin mounting hole, and two ends of the pin are mounted in the pin mounting hole. The pin has an opening and closing position and a locking position in the pin mounting hole, and the pin mounting hole is provided with a bulge between the opening and closing position and the locking position; a locking bulge is arranged at the rear end of the pliers cup; the release locking groove comprises a locking groove section and a release groove section which are communicated with each other; when the pin is located at the locking position, the two pliers cups are closed and locked, and the locking protrusions on the pliers cups are located on the locking groove sections of the release locking grooves. When the pin is located at the opening and closing position, the two pliers cups can be opened or closed, and the locking protrusions on the pliers cups are located at the releasing groove sections of the releasing locking grooves. According to the scheme, the chuck part is firm in clamping and reliable in locking, tissue is prevented from loosening or slipping after being clamped, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a hemostatic forceps and its chuck parts. Background technique [0002] With the extensive development of endoscopic treatment, endoscopic high-frequency resection and electrocoagulation are becoming more and more popular. Local bleeding is a common complication of endoscopic treatment. The high-frequency hemostatic clamp clamps the bleeding vessel or lesion under direct vision of the endoscope, and the purpose of hemostasis can be achieved by passing a high-frequency current. Electrocution of polyps is a common intraoperative operation in clinical practice. Hot biopsyforceps are often used to bite polyps, and high-frequency currents are used to perform electrocution. [0003] When the doctor is performing endoscopic resection and electrocoagulation, the clamp cup is the main active part, so it is only necessary to energize the clamp cup at the front en...
