Problems solved by technology

However, the collet part also has a long stump and the collet part cannot rotate
[0010] Moreover, in the prior art, tubular parts are used to gather clips or clips to realize clamping and locking, which is easy to clamp and lock not firm enough, and the tissue is easy to slip off. Using hooks to realize the release of chuck parts has complicated structure, inconvenient operation, and easy release failed

Embodiment 1

[0056] Such as figure 1 A hemostatic clip shown includes a handle, a sliding handle, a mandrel, a spring hose 80, a chuck and a chuck seat 50, the mandrel is passed through the spring hose 80, and the proximal end of the spring hose 80 is connected to the handle , the far end of the spring hose 80 is connected to the chuck seat 50, the proximal end of the mandrel is connected to the sliding handle, the far end of the mandrel is connected to the two clamp arms 20 through the connector, and the two clamp arms 20 are hingedly arranged on the chuck seat 50 and releasably connected with the collet.

[0057] In this embodiment, the chuck adopts a releasable structure: the chuck includes two clamping arms for clamping tissue and an elastic connecting portion for endowing the two clamping arms with a tendency to clamp. The front end of the arm is a claw end, the elastic connection part is arranged between the two clamping arms, and the rear end of the clamping arm can be clamped by t...

Embodiment 2

[0076] Such as Figure 13 The hemostatic clip shown is only different from Embodiment 1 in that in this embodiment, the two clip arms adopt a parallel connection structure, and the parallel structure uses two pins 21 to respectively set two clip arms 20, so that the two clip arms Arm 20 can do relative or reverse circular motion; Figure 14 , Figure 15 , Figure 16 and Figure 21 As shown, there are two pins 21, and the two clamping arms 20 are respectively hinged with the chuck seat 50 through respective pins 21, and the two mounting arms opposite to the chuck seat 50 are respectively provided with two pin mounting holes, and the pins 21 After passing through the pin hole on the clamp arm 20, the two ends of the pin 21 are installed in the pin mounting hole on the chuck seat 50, so that the two clamp arms 20 are arranged in parallel and facing each other. Other structures are the same as in Embodiment 1.

[0077] In this embodiment, the process of opening, closing, rele...

Abstract

The invention discloses a hemostatic clip and a clip head thereof, the clip head comprises two clamping arm parts used for clamping tissues and an elastic connecting part used for endowing the two clamping arm parts with a clipping trend, the front ends of the clamping arm parts are claw ends, the elastic connecting part is arranged between the two clamping arm parts, and the rear ends of the clamping arm parts can be clamped by the two clamping arms. The clamping heads of the hemostatic clip are in a clamping state in a conventional state, a tubular component is not needed to fold and lock the clip, residual components are few, the size is small, a hook is not needed during releasing, the structure is simpler, operation is more convenient, clamping and locking are firm and reliable, and tissue is prevented from loosening or slipping after being clamped and closed.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a hemostatic clip with a releasable link structure and a clip head thereof. Background technique [0002] With the development of endoscopic technology and other related technologies, endoscopic hemostasis has become the first choice for the treatment of gastrointestinal bleeding. Currently commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of drugs to stop bleeding, drug spraying and hemostatic clips. Among them, the hemostatic clip method has become the most effective non-surgical treatment of gastrointestinal bleeding due to its characteristics of less trauma, faster hemostasis, lower incidence of rebleeding, fewer complications, and definite curative effect. [0003] The hemostatic clip device commonly used in the prior art mainly has two clips to realize the closing function through the hook str...
