Abstract

The invention discloses a microscopic needle holder, mainly including an upper tong head and a lower tong head. The inner side surface of the upper tong head is designed with cross reticulation. The inner side surface of the lower tong head is designed with transverse reticulation. The rear end of the upper tong head is provided with a vertical groove. The rear end of the upper tong head is also provided with a hole B. The front end of the driving rod is vertically flat and transversely perforated. The front end of the driving rod is inserted into the vertical groove of the rear end of the upper tong head and riveted with rivets. The surrounding gap is ground and leveled by laser welding. The needle holder reliably clamps the sewing needle, ensures the precision of sewing, reduces the operation difficulty of the doctor, and improves the operation quality. The driving connection point of the invention is firm, the failure rate is reduced, the service period is prolonged. User use cost is reduced. China has long relied on imported products for such fine instruments. And the needle holder can not only realize domestic substitution for import in response to the call of the state, but also save a large amount of procurement cost for the state.

Description

technical field [0001] The invention relates to the field of laryngology microsurgical wound suturing, in particular to a microneedle holding forceps. Background technique [0002] Existing products of the same kind have jaws with a horizontal tooth structure, and the jaws of the jaws are connected to the drive rod by welding, which has disadvantages such as unstable and unstable clamping of sewing needles, easy desoldering of welding points, and short service life. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a microscopic needle holder. [0004] The purpose of the present invention is accomplished through the following technical solutions: the microscopic needle-holding forceps mainly includes an upper forceps head, a lower forceps head, a throat needle-holding forceps tube, a front handle, a rear handle, a front spring leaf, and a rear spring leaf , lock, drive rod, hole A, cros...
