Articular head separating hook

Abstract

The invention discloses an articular head separating hook, which comprises a nail abutting seat and a separating hook body; the separating hook body is composed of a tip hooking part, a connecting part and an inserting block; a clamping groove is formed in the bottom end of the nail abutting seat; and the clamping groove is matched with the inserting block. The articular head separating hook disclosed by the invention has two states when one surgical instrument is used; furthermore, the two states can be freely switched back and forth; for a surgical target needing the separating hook, a doctor can directly align the cross-shaped inserting block at the tail of the separating hook body to the bottom end of the nail abutting seat; the separating hook body is installed at the bottom end of the nail abutting seat; for a surgical target which does not need the separating hook, the doctor can directly pull out the separating hook body from the nail abutting seat; the instrument can be directly used continuously; the operation can be directly continued without switching the instrument; the design is reasonable; the conception is ingenious; the application range of the instrument can be expanded on the premise that the basic functions of the instrument are guaranteed; and the practicability of the instrument is improved.

Description

technical field [0001] The invention relates to the technical field of laparoscopic surgical instruments, in particular to a joint head separation hook. Background technique [0002] Due to the particularity of the surgery, when certain parts need to be sutured and cut, it is difficult for the front end of the endoscopic component to pass through certain parts, so a separation hook is needed for traction. [0003] However, in the prior art, the separation hooks are generally welded to the nail abutment. Once the instrument is used, it cannot be switched to an instrument without separation hooks. It is necessary to switch to an anvil device without a separation hook to continue the operation, which makes the existing separation hook less applicable and less practical. Contents of the invention [0004] The present invention provides a joint head detachment hook to solve the prior art proposed in the above-mentioned background technology. Generally, the detachment hook is w...
