Abstract

The utility model discloses a pair of medical expansion forceps. The medical expansion forceps comprise forceps jaws, forceps handles, a rotating shaft, a limiting ring, a fixing screw, finger rings, a fixed meshing rack I and a fixed meshing rack II. The rotating shaft is arranged at the joints between the forceps jaws and the forceps handles. The limiting ring is arranged on the outer side of the forceps handles. The limiting ring is connected with the forceps handles through the fixing screw. The finger rings are arranged at the bottom ends of the forceps handles. The fixed meshing rack I is arranged at the joint between one finger ring and the corresponding forceps handle. The fixed meshing rack II is arranged at the joint between the other finger ring and the corresponding forceps handle. The fixed meshing rack I can be meshed with the fixed meshing rack II in a one-way mode. The medical expansion forceps are reasonable in structure and convenient to operate by one hand, and can be expanded freely and effectively ensure smooth performing of operations, and meanwhile the fixed state of the medical expansion forceps can not be unlocked because of misoperation after the medical expansion forceps are fixed.

Description

Medical spreading forceps

Technical field

This utility model relates to field of medical device, relates in particular to a kind of Medical spreading forceps.

Background technology

Medically, when performing the operation to patient, often need with stretching pliers, the skin soft tissue in affected part to be strutted, at present, the stretching pliers using is clinically hook, utilize two single both hands of hook or double both hands to continue firmly operation, bothersome effort, position is fixing unstable, easily causes patient's pain, increase the difficulty of operation, had a strong impact on the process of operation.

Medical spreading forceps of the present utility model, has overcome the problems referred to above, and one-handed performance is convenient, and expansion freely, can be because of maloperation release stationary state after fixing, and can effectively guarantee the smooth enforcement of operation.

Utility model content

The purpose of this utility model is to provide a kind of Medical spreading forceps.

The purpose of this utility model is achieved through the following technical solutions:

Medical spreading forceps of the present utility model, comprises jaw, clamp handle, rotating shaft, spacing collar, hold-down screw, finger ring, fixed engagement tooth bar I and fixed engagement tooth bar II.Rotating shaft is located at the junction of jaw and clamp handle, spacing collar is located at the outside of clamp handle, spacing collar is connected by hold-down screw with clamp handle, finger ring is located at the bottom of clamp handle, fixed engagement tooth bar I is located at the junction of finger ring and clamp handle, fixed engagement tooth bar II is located at the junction of finger ring and clamp handle, and fixed engagement tooth bar I and fixed engagement tooth bar II can one way engagement.

By above-mentioned the technical solution of the utility model, can be found out, Medical spreading forceps described in the utility model, rational in infrastructure, one-handed performance is convenient, and expansion freely, can be because of maloperation release stationary state after fixing, and can effectively guarantee the smooth enforcement of operation.
