Background

When a surgeon needs to connect remaining good tissues after performing surgical excision of a lesion of a tissue of a human body or perform a cutting anastomosis, the surgeon generally uses an anastomat. The principle is as follows: good physiological tissues are kept, and the pathological change part tissues are circularly cut off and simultaneously are instantaneously anastomosed. Not only blocks the blood supply of the operation part, but also suspends and fixes the slipped tissue, and restores the physiological tissue of the pathological state to the normal anatomical state; a common anastomat rod body needs to be sleeved with a silica gel sleeve to prevent a sharp part on the surface from scratching human tissues, the silica gel sleeve needs to be sleeved with an aluminum ring to fix the anastomat rod body through a pipe reducing process, common pipe reducing equipment can impress the anastomat rod body, and the pipe reducing precision is too low to cause the deviation of the sleeved position.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figures 1-4: a clamping chuck structure of an anastomat comprises a chuck body 1, a buffer column 2, a clamping jaw 3 and a limiting push block; a clamping hole is formed in the center of the chuck body 1, and the buffer column 2 is arranged in the clamping hole; the buffer column 2 is of a hollow structure, the top of the buffer column 2 is provided with a yielding hole 21, the bottom of the buffer column 2 is a through hole, a spring 22 is arranged inside the buffer column 2, and the spring 22 extends out of the bottom of the buffer column 2 from the inside of the buffer column 2 along the height direction of the buffer column 2; the plurality of clamping jaws 3 are arranged on the slideway 11 of the chuck body 1 along the circumferential direction of the chuck body 1; the plurality of limiting push blocks are annularly distributed at the top of the chuck body 1; firstly, one end of the anastomat, which is sleeved with the silica gel sleeve, extends into a yielding hole 21, then a limiting push block is manually pushed to limit the distance between aluminum rings at two ends of the silica gel sleeve, a motor is started after the fixing work of the anastomat is completed, the motor drives a thread groove of a chuck body 1 to rotate, a plurality of clamping jaws 3 on the ring side are drawn close to the circle center of the chuck body 1, the clamping jaws 3 contact the aluminum rings and contract the aluminum rings, and the aluminum rings enable the silica gel sleeve to be tightly held on an anastomat rod body; the buffer column 2 is jacked up by the spring 22 at the bottom, so that the top end of the buffer column 2 is contacted with the bottom of the clamping end 311 of the clamping jaw 3, a certain supporting buffer is provided for the clamping end 311, and the phenomenon that the clamping end 311 sags due to factors such as gravity when being tightened to cause the aluminum ring to deviate from a set position is avoided.

The jaw 3 comprises a clamping block 31; the two ends of the clamping block 31 along the height direction are respectively provided with a clamping end 311; the clamping end 311 is in an arc structure, the diameter of the arc of the clamping end 311 is the same as that of the anastomat rod, and the thickness of the clamping end 311 is equal to that of the anastomat aluminum ring; the two sides of the clamping end 311 in the horizontal direction are provided with relief areas 312; due to the fact that a gap exists between the clamping ends 311 due to machining tolerance, the clamped anastomat rod body can generate indentation, and when the yielding area 312 is arranged, the yielding position of the joint of the adjacent clamping ends 311 can be generated, and damage to the anastomat rod body is avoided.

The limiting push block comprises a fixed seat 41, a push handle 42 and a limiting block 43; the fixing seat 41 is fixedly connected to the chuck body 1, the limiting block 43 is slidably connected to the fixing seat 41, and the limiting end 431 faces to the direction of the center of the chuck body 1; the pushing handle 42 is connected to the pushing end 432 of the limiting block 43; the height of the limiting end 431 is equal to that of a silica gel sleeve between aluminum rings at two ends of the anastomat; the pushing handle 42 is pushed to push the limiting end 431 to the anastomat rod body, and as the height of the limiting end 431 is equal to that of the silica gel sleeve between the aluminum rings, the limiting end 431 can be pressed into the silica gel sleeve to be embedded between the aluminum rings at two ends, so that the effect of limiting the aluminum rings is achieved, and the position accuracy of clamping the silica gel sleeve by the aluminum rings is ensured.
