The utility model discloses a pair of ultramicro wound operating
forceps with an adjustable force arm, which comprises a
forceps head, a puncture component, a locking sleeve, a support rod and a
handle which are structurally separated from each other, the
forceps head and the front end of the puncture component can be separated and connected through threads, and the locking sleeve can be annularly sleeved on the puncture component and axially slide along the puncture component. The
tail end of the puncture
assembly can penetrate through the supporting rod to be connected with and separated from the
handle, the front end of the supporting rod can be connected with and separated from the locking sleeve, and the
tail end of the supporting rod can be connected with and separated from the
handle. According to the scheme, a locking structure is moved forwards, the structure of an existing instrument is simplified, and rapid assembling of the instrument is facilitated; according to the scheme, the locking structure is improved, the locking sleeve is used for guiding, and jamming between the needle tube and the supporting rod is avoided; according to the structural design of the scheme, the problem that
assembly cannot be achieved due to the fact that the puncture
assembly is uneven in stress after puncture is completed can be solved.
