[0021] Embodiment one

[0022] With reference to Figures 1-4 A digestive tract soft tissue fixing clamp, comprising two opposite clamp bodies 1, a crossbar 2 is slidably arranged in the clamp body 1, the two ends of the crossbar 2 are fixed with fixing frames 3, a spring 1 4 is sleeved on the outer surface of the crossbar 2, the two ends of the spring 1 4 are fixedly connected with the clamp body 1 and the fixing frame 3 respectively, a locking mechanism for locking the two clamp bodies 1 is arranged in the clamp body 1, the locking mechanism comprises a sliding rod 91 fixed on the left clamp body 1, an L-shaped locking rod 92 is fixed on the sliding rod 91, and a buffer assembly is further arranged on the clamp body 1.

[0023] Further, a pull rod 5 is slidably arranged on the fixing frame 3, the bottom end of the pull rod 5 is fixed with a lifting strip 6, the bottom of the lifting strip 6 is fixed with a limiting rod 7, and the top of the clamp body 1 is provided with a limiting hole 8, when the limiting rod 7 slides out of the limiting hole 8, the two clamp bodies 1 are close to each other to fix the soft tissue.

[0024] Further, the locking mechanism further comprises a locking channel 93 arranged on the right clamp body 1, an installation groove 94 is further arranged in the right clamp body 1, the locking channel 93 and the installation groove 94 are in communication, and the sliding rod 91 is slidably connected with the L-shaped locking rod 92 and the locking channel 93.

[0025] Further, an extrusion rod 95 is slidably arranged in the installation groove 94, the bottom end of the extrusion rod 95 is fixed with an arc-shaped block 96, a spring 2 97 is sleeved on the outer surface of the extrusion rod 95, and the two ends of the spring 2 97 are fixedly connected with the arc-shaped block 96 and the clamp body 1 respectively.

[0026] Before using the soft tissue fixation clamp of the digestive tract, in the initial state, the clamp body 1 is in the open state, the L-shaped locking rod 92 on the slide rod 91 is not in contact with the locking hole 98 on the arc block 96, when the fixed position is determined, the endoscopic tool is operated to pull the pull rod 5, the pull rod 5 drives the lifting bar 6 to rise, so that the limiting rod 7 slides out of the limiting hole 8 of the clamp body 1, at this time, under the elastic force of the spring one 4, the two clamp bodies 1 begin to close to the middle, with the closing of the clamp body 1, the slide rod 91 drives the L-shaped locking rod 92 to move along the locking channel 93 to the mounting groove 94 direction, when the L-shaped locking rod 92 contacts the arc block 96, because the arc block 96 is supported by the elastic force of the spring two 97, the L-shaped locking rod 92 will extrude the arc block 96 and make the spring two 97 compressed, until the L-shaped locking rod 92 slides into the locking hole 98 of the arc block 96, at this time, the two clamp bodies 1 are stably locked, the fixation of the soft tissue is completed, if it is needed to take out the fixation clamp later, a certain external force can be applied to the arc block 96 through the endoscopic tool, so that the L-shaped locking rod 92 is detached from the locking hole 98, the locking state is released, and the clamp body 1 can be opened and taken out.

[0027] Further benefits are: through the setting of the locking mechanism, located at the connecting part of the clamp body 1, a buckle type locking structure is adopted, when the clamp body 1 is closed, the two buckles are locked with each other to ensure the stability of the clamp body 1 in the closed state, the buckle has a certain elasticity and can be unlocked when a certain external force is applied, which is convenient for taking out the clamp body 1 when needed.

[0028] Based on example one, example two is proposed:

[0029] Refer to Figures 1-4 ,

[0030] Further, the arc block 96 is provided with a locking hole 98, and the L-shaped locking rod 92 is in sliding connection with the locking hole 98, when the L-shaped locking rod 92 slides into the locking hole 98, the two clamp bodies 1 are locked with each other.

[0031] Further, the buffer assembly includes an elastic silica gel 101 fixed on the clamp body 1, and the elastic silica gel 101 is provided with anti-skid tooth patterns 102.

[0032] When the fixed clamp is closed to fix the soft tissue in the digestive tract, the elastic silica gel 101 on the clamp body 1 first contacts the soft tissue. Since the elastic silica gel 101 has good elasticity and flexibility, during the process of the clamp body 1 applying clamping force, the elastic silica gel 101 will be elastically deformed to a certain extent, thereby absorbing part of the pressure transmitted by the clamp body 1, avoiding damage to the soft tissue caused by excessive impact force. At the same time, the anti-skid tooth pattern 102 on the elastic silica gel 101 is in close contact with the surface of the soft tissue. The shape and distribution of the anti-skid tooth pattern 102 are designed to effectively increase the friction between the anti-skid tooth pattern 102 and the soft tissue without damaging the soft tissue. For example, during physiological activities such as gastrointestinal peristalsis, even if there is a certain external force, due to the friction of the anti-skid tooth pattern 102, the fixed clamp can be stably fixed on the soft tissue and will not easily displace or fall off. Moreover, when the soft tissue is slightly displaced or deformed due to physiological activities, the elastic silica gel 101 can be elastically deformed accordingly, thereby maintaining good contact with the soft tissue and stable clamping force, further improving the stability and safety of the fixed clamp.

[0033] Further benefits are: by the arrangement of the buffer assembly, when the clamp body 1 is closed to clamp the soft tissue, the buffer assembly can play a buffering role to avoid damage to the tissue caused by excessive pressure of the clamp body 1, and can adapt to the slight displacement and deformation of the tissue during physiological activities, further improving the stability and safety of the fixed clamp. Moreover, by the arrangement of the anti-skid tooth pattern 102, the shape and distribution of the anti-skid tooth pattern 102 are optimized and designed to effectively increase the friction between the anti-skid tooth pattern 102 and the soft tissue, prevent the clamp body 1 from falling off, and not excessively damage the tissue.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
