Background

Fracture refers to complete or partial fracture of bone structure, which is often seen in children and the elderly, and sometimes occurs in young and middle-aged people due to external force. Screw-steel plate internal fixation is a common surgical procedure in fracture surgery, which utilizes a steel plate to be fixed on the bone surface and the traction reduction of screws to achieve the purposes of fixation and promotion of bone growth. The existing steel plate sleeve does not have a resetting function, when in screw-steel plate internal fixation, an operator needs to fix a steel plate on the bone surface of a fracture part, then the steel plate sleeve is in threaded connection with the steel plate, then a drill bit is inserted into the fracture part along the steel plate sleeve to drill a fixing screw hole, then a fracture resetting drag hook is needed to be matched with an independent positioning and guiding device to be inserted into the fracture part to pull a fracture block for resetting, the operation mode needs to carry out secondary positioning and guiding operation, and the operation mode is complicated; meanwhile, the existing fracture reduction draw hook is difficult to be suitable for the conditions of deeper fracture part and narrow operation incision.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model designs a steel plate sleeve with an auxiliary reset function, which solves the problem that the traditional steel plate sleeve needs to be positioned and guided for the second time after drilling, and can be positioned and guided for the first time, thereby simplifying the operation steps; meanwhile, the reduction draw hook provided by the sleeve can be used for the situations of narrow operation incision and deeper operation position.

In order to solve the above technical problem and achieve the above technical effect, the utility model discloses a following technical content realizes:

a steel plate sleeve with an auxiliary reset function is characterized by comprising a sleeve body and reset hooks, wherein reset hook guides are fixedly connected to two sides of the sleeve body, a through reset channel is formed in each reset hook guide, the reset hooks are inserted into the reset channels of the reset hook guides, and the reset hooks can slide and rotate along the reset channels;

the top of the sleeve body is provided with a rotating part, the bottom of the sleeve body is provided with a threaded connecting part, and the center of the sleeve body is provided with a through long drilling channel;

the reset hook guider is of a cylindrical structure, and the reset channel penetrates through the reset hook guider and is eccentrically arranged on one side of the reset hook guider;

the top of the reset hook is a thread screwing part, the bottom of the reset hook is a hook tip, and an included angle between the hook tip and the reset hook is an acute angle.

Preferably, the sleeve body and the reset hook are made of stainless steel materials.

The utility model has the advantages that: the sleeve solves the problem that the traditional steel plate sleeve needs to be subjected to secondary positioning and guiding operation after drilling, and can be completed by primary positioning and guiding, so that the operation steps are simplified; meanwhile, the reduction draw hook provided by the sleeve can be used for the situations of narrow operation incision and deeper operation position.
