Problems solved by technology

The rongeur is generally used in the joint treatment of the human body. The purpose of the rongeur in the prior art is single, and the operating efficiency and operating flexibility are very poor, which affects the therapeutic effect of the operation.
Due to the special purpose of the rongeur, the steel requirements for making it are particularly high and the price is high. Each operation requires a variety of different rongeurs to complete successfully. The number of instruments used increases, the cost of the operation is high, and the preparation tasks before the operation are cumbersome.
The strength of general rongeurs is difficult to grasp. Different types of rongeurs are required for different bones to complete a surgery, which makes the original simple surgery complicated.

Abstract

The invention discloses a pair of rongeurs with rongeur heads replaceable. The pair of rongeurs comprises upper supports and lower supports, wherein a rotary shaft is arranged between the upper supports and the lower supports, a spring sheet is arranged between the lower supports, and a handheld handle and a free handle are arranged between the upper supports. First pulleys are symmetrically arranged on the two sides of the handheld handle, second pulleys and third pulleys are symmetrically arranged at the upper ends and the lower ends of the two sides of the upper supports, and one end of the free handle is connected with a pull wire which sequentially passes by the first pulleys, the second pulleys and the third pulley, penetrates through the spring sheet and intersects to be fixed to the lower supports. Rongeur connection heads are arranged at the ends of the lower supports far away from the handheld handle and connected with double-joint rongeur heads or vertebral plate rongeur heads or olecranon rongeur heads. The rongeur connection heads are provided with threads and are in threaded connection with the double-joint rongeur heads or the vertebral plate rongeur heads or the olecranon rongeur heads. The pair of rongeurs with the rongeur heads replaceable has the advantages of being convenient to use and controllable in strength, and the rongeur heads are replaceable.

Description

technical field [0001] The invention relates to the field of medical accessories, in particular to a rongeur with replaceable pliers heads. Background technique [0002] Medical accessories are generally used alone or in combination during the treatment process. They are used on the surface of the human body or inside the body, and play a certain auxiliary role in the treatment process. The rongeur is generally used in the joint treatment of the human body. In the prior art, the purpose of the rongeur is single, and the operation efficiency and flexibility are poor, which affects the therapeutic effect of the operation. Due to the special purpose of the rongeur, the steel requirements for making it are particularly high and the price is high. Each operation requires a variety of different rongeurs to complete successfully. The number of instruments used increases, the cost of the operation is high, and the preparation tasks before the operation are cumbersome. The strength ...
